Improve the technical realization elements of the handle

Technical implementation elements:

3. In view of the problems existing in the prior art, the present invention provides a lifting handle, which solves the problem that the lifting handle is easy to loosen in the prior art.

4. In order to achieve the above purpose, the present utility model provides the following technical solutions: a lifting handle, comprising a handle body, a connecting sleeve, a square steel, a handle seat and a shell, and the handle body is in cooperation with the handle seat. A first square groove is opened inwardly on the end face of the socket, the first square groove is provided with a connecting sleeve that is inserted and matched with it, and the part where the connecting sleeve is matched with the first square groove is set in a square shape, and the relative square part is The other end is provided with a boss, and a connecting piece connecting the boss and the square part, the connecting sleeve is provided with a second square groove inwardly on the end face of one side of the boss, which can be inserted and matched with the square steel. The hand seat corresponds to the connecting sleeve with a matching hole through which the connecting piece and the square part can pass. The size of the matching hole is smaller than that of the boss. The bottom of the first square groove is provided with a first connecting hole. The first connecting hole There is an internal thread in the middle, the bottom of the second square groove is provided with a second connection hole corresponding to the first connection hole and a nut accommodating groove, the first connection hole, the second connection hole and the nut accommodating groove are A connecting screw is assembled, a locking piece is arranged in the handle seat, and a mounting hole that can be matched with the boss and a locking groove communicated with the mounting hole are opened on the locking piece, and the locking groove is provided with The two are respectively arranged on both sides of the locking piece in the length direction and are symmetrically arranged. The locking groove is provided with a limit spring and a steel ball, and the steel ball is squeezed by the limit spring at the position where the locking groove and the installation hole communicate with each other. , and a part of the boss extends into the installation hole, and the boss is provided with a card slot corresponding to the part where the steel ball extends into the installation hole.

5. Using the above technical solution, the handle body and the handle seat are connected together by a connecting sleeve, and one end of the connecting sleeve is inserted into the first square groove on the handle body to connect with the handle body. , the other end is axially limited by the boss to the handle seat, so that the handle body and the handle seat can be rotatably connected, so that the rotation of the handle body can drive the connecting sleeve and the square steel to rotate, and the connecting sleeve is inserted into the first The square part in the square groove is fixed with the handle body through the connection of the connecting screw, and the connecting screw is arranged in the first connecting hole, the second connecting hole and the nut accommodating groove, so as to avoid the loosening of the handle due to the loosening of the screw, and the locking The steel ball can be pushed by the limit spring to make a part of it extend into the installation hole and cooperate with the card slot to lock the boss, which can effectively avoid the loosening of the handle, and solve the problem of easy loosening of the lifting handle in the prior art. , and the assembly is simple and the disassembly is convenient.

6. Further, a dust cover is provided between the handle body and the handle seat, and the dust cover is provided with four symmetrically arranged connection blocks on the end face of the side facing the handle seat. The handle seat is provided with a connection hole corresponding to the connection block, a first dust ring is provided on one side of the dust cover corresponding to the handle body, and a second dust ring is provided on one side corresponding to the handle seat. Place

The second dustproof ring is arranged between the matching hole and the connecting piece.

7. Using the above technical solution, the dust cover can be installed to prevent dust from entering the installation gap between the handle body and the handle seat, and the connection block can be matched with the connection hole to play a positioning role, so that the dust cover is fixed in the handle. On the hand seat, the first dustproof ring seals the gap between the dust cover and the handle body, and the second dustproof ring seals the gap between the matching hole and the connecting piece, and replaces the matching hole and the connecting piece. make contact.

8. Further, the outer casing is sleeved outside the handle seat, and a corresponding gap is formed corresponding to the dust cover, and the side surface of the handle seat is provided with several clamping blocks along the circumferential direction.

9. With the above technical solution, the arrangement of the clamping block enables the handle seat to have an interference fit with the housing, so that the fit between the housing and the handle seat is tighter and avoids loosening of the housing.

10. Further, the two ends of the locking member corresponding to the length direction are respectively provided with positioning grooves, the handle seat is provided with a positioning block corresponding to the positioning groove, and the locking member is on the end face where the positioning groove is located. There are fixed blocks on the other two sides of the neighbor.

11. With the above technical solution, the locking member can be fitted with the handle seat through the cooperation between the positioning groove and the positioning block, and embedded in the handle seat, and the setting of the fixing block makes the locking member and the handle seat. The interference fit between the hand seat plays a fixed role on the locking piece.

12. Further, the handle seat is provided with screw holes for mounting screws, and the positions of the screw holes are provided with mounting sleeves extending in the axial direction, and the mounting sleeves are integrally formed with the handle seat.

13. Using the above technical solution, the installation of the installation sleeve can play the role of positioning and dustproof. On the one hand, it can make the installation of the screw more firm and reliable, and on the other hand, it can prevent the dust from contacting the screw and protect the screw.
