Referring to fig. 1 to 4, in this embodiment, the handle assembly includes a handle 2, a reversing block 1, and a fixed cylinder 3. The handle 2 is a hollow shell, which is formed by buckling a handle main body 21 and an outer cover 22, the handle main body 21 and the outer cover are clamped or bolted together, and a cavity for accommodating the replaceable guide block 1 is formed in the middle. The handle main body 21 is positioned at one side close to the fixed cylinder 3 and is used for being connected with the reversing block 1 and the fixed cylinder 3 at the side; the outer cover 22 is located on the side away from the fixed cylinder 3 as a decorative housing for concealing the structure in the handle 2. In other embodiments, the handle body 21 and the cover 22 may be provided as a single piece.

The inner side of the handle 2 is also provided with a mounting hole 23 for connecting the handle with the fixed cylinder 3, wherein one end of the handle main body 21 is semicircular, and the outer cover 22 is provided with a semicircular structure opposite to the semicircular structure to form the mounting hole 23. One end of the fixed cylinder 3, which is close to the handle 2, is arranged in the mounting hole 23, the periphery of the fixed cylinder is provided with a limiting clamping table 31 protruding outwards, meanwhile, the inner wall of the mounting hole 23 is provided with a limiting baffle 28, and the side surface of the limiting clamping table 31 is abutted against the inner side of the limiting baffle 28, so that the handle 2 can be prevented from falling off from the fixed cylinder 3. The other end of the fixed cylinder 3 is fixedly connected with the door lock and the door when in use, and can play a role of fixing the handle. When the fixed cylinder 3 is used, a linkage structure which connects the handle 2 with the square core of the door lock is arranged in the fixed cylinder, one end of the linkage structure is connected with the square core, and the other end of the linkage structure is connected with the handle, and the square core can be driven to rotate by rotating or pushing and pulling the handle, so that unlocking is realized.

Specifically, in this embodiment, the handle 2 is connected to the other end of the interlocking structure through a connecting portion 4 provided in the fixed cylinder 3. The connecting part 4 is arranged in the fixed cylinder 3 in a sliding way, can slide along the axial direction of the fixed cylinder 3, and one end of the connecting part 4 is inserted in the handle 2 and can synchronously rotate with the handle 2. When the handle 2 is required to be reversed, the connecting part 4 is pushed into the fixed cylinder 3, the assembly relation between the connecting part and the handle 2 is released, and the handle 2 can be independently rotated to realize reversing. Therefore, only the connection relationship between the connecting portion 4 and the handle 2 is described in the present disclosure, and the connection relationship between the connecting portion 4 and the linkage structure is not an innovation point of the present disclosure, so that no further description is provided.

The reversing block 1 is arranged between a handle main body 21 and an outer cover 22, one end of the reversing block 1 is provided with a shifting block 11 opposite to a mounting hole 23, the other end of the reversing block is provided with a pressing part 12, and the middle part of the reversing block is provided with a hinge shaft 13 and is hinged on the shell. One end of the handle body 21, which is far from the mounting hole 23, is opened, and after being engaged with the housing 22, a reversing hole 24 is formed. The pressing portion 12 is a rectangular frame, and is disposed in the reversing hole 24, and a user can press the pressing portion 12 from the outside of the handle 2. The shifting block 11 is a strip-shaped plate body, and the front end of the shifting block is arranged in the mounting hole 23. The housing 22 is provided with a shaft hole 25 for accommodating the hinge shaft 13. When the pressing part 12 is pressed into the handle 2, the shifting block 11 moves to the outer side of the mounting hole 23, so that the linkage structure in the fixed cylinder moves to the side far away from the handle 2, the connection with the handle 2 is released, and the handle 2 is conveniently rotated to change the direction.

Since the hinge shaft 13 is rotatably connected in the shaft hole 25 on the outer cover 22, and one side of the reversing block 1 is close to the handle body 21, in order to ensure that the reversing block 1 is not affected by the handle body 21 during rotation, a second limiting groove 26 for the reversing block 1 to pass through is further formed in the handle body 21.

In this embodiment, four first limiting grooves 41 are symmetrically provided on the end face angle of the connecting portion 4 in the mounting hole 23, the first limiting grooves 41 are grooves, and the dial 11 is disposed in the first limiting grooves 41. An inward concave clearance groove 42 is arranged in the center of the end face of the first limit groove 41, which is close to the connecting part 4, and as shown in fig. 3, the side wall of the clearance groove 42 is an inclined surface which is arranged on one side of the first limit groove 41 and is inclined towards the inside of the connecting part 4, so that the first limit groove 41 can be prevented from being contacted with the shifting block 11 when the handle reversing operation is performed. In other embodiments, the clearance groove 42 may be a circular groove recessed toward the inside of the connecting portion 4, which can also serve the above-mentioned purpose. Specifically, when the handle assembly works normally, the handle 2 is rotated, and the shifting block 11 contacts with the first limiting groove 41, so that the connecting part 4 can be driven to rotate simultaneously; when the handle reversing operation is performed, the front end of the shifting block 11 moves towards the center of the connecting part 4, and the shifting block 11 is not positioned in the first limiting groove 41 due to the existence of the clearance groove 42 while the connecting part 4 is pushed to move, and the handle 2 is rotated at the moment, so that the connecting part 4 is not rotated at the same time, and the reversing of the handle is realized.

In this embodiment, four first limiting grooves 41 are provided in angular symmetry, so that in the reversing process of the handle, after each 90 ° rotation of the handle, the shifting block 11 can be opposite to the first limiting grooves 41 again, so as to facilitate the orientation of the handle. In other embodiments, the number of the first limiting grooves 41 may be changed to adjust the minimum rotation angle when the handle is turned, but the number of the first limiting grooves 41 should be ensured to be not less than 2.

In still another embodiment, the end surface of the connecting portion 4 located in the mounting hole 23 is formed in a regular polygon or ellipse, and accordingly, an assembly groove 27 of the same shape is provided in the mounting hole 23, and one end of the connecting portion 4 is inserted into the assembly groove 27, so that the connecting portion 4 can be rotated as well when the handle 2 is rotated. One side of the shifting block 11 is abutted against the inner wall of the housing 22, and the other side is abutted against the end face of the connecting portion 4. When the handle reversing operation is performed, the front end of the shifting block 11 moves towards the center of the connecting part 4, the connecting part 4 can be pushed out of the assembly groove 27, the connection relationship between the connecting part and the handle 2 is released, and at the moment, the handle 2 is rotated, and the connecting part 4 cannot be simultaneously rotated, so that the reversing of the handle is realized.

In this embodiment, the end face of the connecting portion 4 located in the mounting hole 23 is square, so that the end face of the connecting portion 4 can be opposite to the fitting groove 27 again after every 90 ° rotation of the handle during the handle reversing process, so that the handle can be oriented. In other embodiments, when the end surface of the connecting portion 4 located in the mounting hole 23 is elliptical, the end surface of the connecting portion 4 may be opposite to the fitting groove 27 again after each 180 ° rotation of the handle during the reversing of the handle; when the end surface of the connecting portion 4 located in the mounting hole 23 is in the shape of a regular octagon, the end surface of the connecting portion 4 may be opposite to the fitting groove 27 again after each 45 ° rotation of the handle during the reversing process of the handle. Therefore, the user can set the end surface shape of the connecting part 4 according to the actual requirement, thereby adjusting the minimum rotation angle when the handle is reversed.

Further, in this embodiment, the dial 11 is disposed at an obtuse angle to the pressing portion 12, the dial 11 is abutted against the inner wall of the housing 22 in the initial state, the pressing portion 12 is abutted against the inclined surface in the handle body 21, and one end is located outside the reversing hole 24. When the handle is operated in reverse, the pressing portion 12 moves away from the handle body 21 toward the inside of the handle 2, and the dial 11 moves away from the inner wall of the housing 22 toward the connection portion 4. Under this kind of structure, reversing block 1 rotates less angle, can accomplish handle switching-over operation, can reduce the thickness of handle 2.

In this embodiment, a return spring 5 is further provided in the fixed cylinder 3, and one end of the return spring 5 is fixed and the other end thereof abuts against the connecting portion 4, so that a force toward the mounting hole 23 is applied to the connecting portion 4. Therefore, after the handle 2 finishes the steering, the return spring 5 can push the connecting portion toward the mounting hole 23, and the connecting relationship is realized with the handle again, so as to realize the unlocking function.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
