In this embodiment, a handle assembly is shown, and fig. 1 shows a cross-sectional structure of the handle assembly; FIGS. 2a and 2b illustrate exploded configurations of the handle assembly at two different viewing angles; FIG. 3 shows the structure of the fixing seat in the handle assembly; fig. 4a and 4b show the structure of the handle in the handle assembly at two different viewing angles.

Referring to fig. 1 to 4b, the handle assembly includes: handle 1, fixing base 2, spacing slider 3, reset spring 4 and switching-over piece 5. The fixing seat 2 is provided with a first limiting hole 21 and a second limiting hole 22, and the first limiting hole 21 is of a circular structure and is used for being connected with the handle 1. One end of the fixing base 2 is provided with a mounting panel 23 for mounting the handle assembly on a door lock. In this embodiment, a lock core hole 24 is further provided on the mounting panel 23, and when the handle is mounted, the lock core hole 24 is opposite to the lock core of the door lock, so that a user can unlock the door by using a mechanical key. In other embodiments, the lock core hole 24 may be provided on a panel of the door lock, so long as the handle 1 can form a shield for the door lock.

The handle 1 has a hollow holding portion 11, the holding portion 11 is formed by buckling two half-shells, a cavity capable of accommodating other structures is formed in the middle, and in the drawings of this embodiment, only the shell on one side of the holding portion 11 is shown to show the internal structure thereof. A rotating shaft 12 rotatably connected in the first limiting hole 21 is arranged on one side of the holding part 11 close to the fixed seat 2, and the rotating shaft 12 has a circular structure and can only rotate in the first limiting hole 21. A first through hole 13 and a second through hole 14 facing the second limiting hole 22 are further arranged on one side of the holding part 11 close to the fixed seat 2 and used for installing the reversing block 5.

The limit slider 3 is slidably disposed in the second limit hole 22, and one end of the limit slider, which is close to the holding portion 11, is provided with a clamping connector 6 extending into the second through hole 14. The external dimension of the clamping connector 6 is smaller than that of the limit slider 3, so that when the limit slider 3 moves to the holding part 11 side, only the clamping connector 6 can be inserted into the second through hole 14. After the bayonet connector 6 is inserted into the second through hole 14, the rotation shaft 12 can be limited to rotate around the first limiting hole 21, in other words, the handle 1 cannot rotate on the fixing seat 2. The cross section of the limit sliding block 3 and the cross section of the second limit hole 22 are rectangular, so that the limit sliding block 3 can be prevented from rotating.

The return spring 4 is disposed in the second limiting hole 22, and one end thereof is fixed, and the other end thereof abuts against the limiting slider 3, and applies a force to the limiting slider 3 toward the second through hole 14, so that the bayonet joint 6 can be positioned in the second through hole 14 to limit the rotation of the handle 1.

The reversing block 5 is arranged in the holding part 11, the middle part of the reversing block is hinged on the handle 1, one end of the reversing block faces the first through hole 13, and the other end of the reversing block is abutted on the end face of the clamping connector 6. As shown in fig. 1, 2b and 4b, an assembly groove 15 communicating with the inner cavity of the holding part 11 is provided at one end of the rotating shaft 12 near the holding part 11, a shaft hole is provided in the assembly groove 15, a connecting part 51 extending into the assembly groove 15 is provided at the middle part of the reversing block 5, and a shaft hole is also provided at the connecting part 51, and the middle part of the reversing block 5 is hinged in the assembly groove 15 by inserting a pin shaft into the shaft hole. The structure can realize that the reversing block 5 is rotatably arranged in the handle 1, and can also reduce the thickness of the handle 1. The user can press the reversing block 5 to the inside of the handle 1 through the first through hole 13, and the other end of the reversing block 5 can move toward the outside of the second through hole 14.

When the handle assembly is used, the handle 1 is limited by the clamping connector 6, cannot rotate in the first limiting hole 21, and can shield the lock cylinder hole 24 on the inner side of the handle 1; when the mechanical key is needed, one end of the reversing block 5 is pressed into the handle 1 through the first through hole 13, the other end of the reversing block 5 can push the clamping head 6 to move into the second limiting hole 22, the limitation on the handle 1 is relieved, the handle 1 can be rotated at the moment, and the lock cylinder hole 24 is exposed. While the above description has been made with respect to the function of shielding the handle assembly by taking the cylinder hole as an example, it goes without saying that this structure can also be used for shielding a part of the structure provided on the mounting panel 23 or the door lock panel, such as other power supply insertion holes.

In order to improve the stability of the handle 1, the cross-sectional shape of the clamping connector 6 is the same as that of the second through hole 14, for example, the clamping connector 6 is rectangular or circular, and when the clamping connector 6 is arranged in the second through hole 14 in a penetrating manner, the shaking amplitude of the handle 1 in the use process can be reduced.

In this embodiment, in order to further improve stability of the handle 1, shaking of the handle 1 during use is prevented, and the rotation shaft 12 is further limited by the limiting slider 3. Specifically, the side surfaces of the first limiting hole 21 and the second limiting hole 22 are configured to be communicated, a first limiting surface 16 is provided on one side of the rotating shaft 12 close to the second limiting hole 22, and as shown in fig. 1, one end of the first limiting surface 16 close to the handle 1 is inclined to one side of the second limiting hole 22, that is, the right side is inclined downward; a second limiting surface 31 parallel to the first limiting surface 16 is arranged on one side of the limiting slider 3 close to the first limiting hole 21.

In use, the return spring 4 pushes the limit slider 3 to the right in fig. 1, so that the clamping head 6 is inserted into the second through hole 14, and the second limit surface 31 abuts against the first limit surface 16. Because the second limiting surface 31 and the first limiting surface 16 are both inclined towards the lower right side in fig. 1, the acting force between the limiting slider 3 and the rotating shaft 12 is gradually increased in the process of moving towards one side of the handle 1, so that the limiting slider 3 can be simultaneously abutted against the inner wall of the second limiting hole 22, and the rotating shaft 12 can be simultaneously abutted against the inner wall of the first limiting hole 21, thereby ensuring that the handle 1 does not shake in the use process. In this embodiment, the first limiting surface 16 and the second limiting surface 31 are a plane, and in other embodiments, they may be curved or bent with a downward right side, which may also serve to fix the rotating shaft 12. The contact length of the first limiting surface 16 and the second limiting surface 31 is not more than the insertion length of the clamping connector 6 into the second through hole 14. Therefore, when the handle 1 needs to be rotated, after the reversing block 5 pushes the clamping connector 6 out of the second through hole 14, the first limiting surface 16 and the second limiting surface 31 can be prevented from contacting each other, so that the rotation restriction on the rotating shaft 12 is released.

In yet another embodiment, the first limiting surface 16 may be disposed outside the first limiting hole 21, and at this time, even if the side surfaces of the first limiting hole 21 and the second limiting hole 22 are not communicated, the first limiting surface 16 and the second limiting surface 31 may abut against each other, so as to limit rotation of the rotating shaft 12.

The rotation shaft 12 is rotatably disposed in the first limiting hole 21, and its displacement in the axial direction of the first limiting hole 21 is limited. The left end of the rotating shaft 12 passes through the first limiting hole 21 and is positioned at the left side of the fixed seat 2, and a positioning structure 7 is arranged at the left end so as to limit the handle 1 to move to the side far away from the fixed seat 2. Specifically, in this embodiment, an external thread is provided at the left end of the rotation shaft 12, and the positioning structure 7 is a fastening nut that is sleeved on the external thread. In other embodiments, other fasteners such as pins may be used to limit the handle 1.

In this embodiment, in order to prevent the return spring 4 from shaking during use, the movement of the limit slider 3 is affected. A spring positioning column 8 fixedly connected to the fixed seat 2 is arranged in the second limiting hole 22, and the left end of the return spring 4 is sleeved on the spring positioning column 8. An inward-sinking spring positioning groove 9 is formed in the left end of the limiting sliding block 3, and one end, far away from the fixed seat 2, of the reset spring 4 is inserted into the spring positioning groove 9. By fixing both sides of the return spring 4, it is enabled to operate stably.

Fig. 5 shows the structure of the fixing base 2 in a further embodiment of the present invention, in this embodiment, a protection cover 25 is further disposed on the fixing base 2 opposite to the lock cylinder hole 24, and the protection cover 25 is disposed outside the lock cylinder hole 24, so as to prevent dust from entering the lock cylinder hole 24.

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.
