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. Be equipped with first spacing hole 21 and the spacing hole of second 22 on the fixing base 2, first spacing hole 21 is circular structure for be connected with handle 1. One end of fixing base 2 is equipped with installation panel 23, can be used to install this handle subassembly on the lock. In this embodiment, a lock cylinder hole 24 is further provided on the mounting panel 23, and when the handle is mounted, the lock cylinder hole 24 is opposite to the lock cylinder of the door lock, so that a user can unlock the door lock conveniently by using a mechanical key. In other embodiments, the lock cylinder hole 24 may be provided on the panel of the door lock, so as to ensure that the handle 1 can shield the lock cylinder hole.

The handle 1 has a hollow holding portion 11, the holding portion 11 is formed by two half shells fastened together, a cavity capable of accommodating other structures is formed in the middle, in the drawings of the embodiment, only the shell on one side of the holding portion 11 is shown to show the internal structure. 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 is also of 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 formed in one side, close to the fixed seat 2, of the holding portion 11, and used for installing and arranging the reversing block 5.

The limiting slide block 3 is arranged in the second limiting hole 22 in a sliding manner, and one end of the limiting slide block, which is close to the holding part 11, is provided with a clamping joint 6 extending into the second through hole 14. The outer dimension of the card connector 6 is smaller than the outer dimension of the position limiting slide block 3, so that only the card connector 6 can be inserted into the second through hole 14 when the position limiting slide block 3 moves towards the holding part 11 side. After the bayonet joint 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 fixed seat 2 at this time. The cross section of the limiting slide block 3 and the cross section of the second limiting hole 22 are rectangular, so that the limiting slide block 3 can be prevented from rotating.

The return spring 4 is disposed in the second limit hole 22, and one end thereof is fixed while the other end thereof abuts against the limit slider 3, and applies an acting force toward the second through hole 14 to the limit slider 3, so that the latch 6 can be positioned in the second through hole 14 to restrict 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 abuts against 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 portion 11 is provided at one end of the rotating shaft 12 close to the holding portion 11, a shaft hole is provided in the assembly groove 15, a connecting portion 51 extending into the assembly groove 15 is provided at the middle portion of the reversing block 5, and the connecting portion 51 is also provided with a shaft hole, and a pin shaft is inserted into the shaft hole to hinge the middle portion of the reversing block 5 in the assembly groove 15. This kind of structure can realize that switching-over piece 5 rotates and sets up in handle 1, can also reduce handle 1's thickness. The user can press switching-over piece 5 to handle 1 inside through first through-hole 13, and the other end of switching-over piece 5 can move towards the outside of second through-hole 14.

When the handle assembly is used, the handle 1 is limited by the clamping joint 6 and cannot rotate in the first limiting hole 21, so that the lock cylinder hole 24 in the inner side of the handle 1 can be shielded; when needing to use mechanical key, press the one end of switching-over piece 5 in to handle 1 through first through-hole 13, the other end of switching-over piece 5 can push joint 6 and remove in the spacing hole 22 of second, removes the restriction to handle 1, can rotate handle 1 this moment, makes lock core hole 24 expose. The shielding function of the handle assembly is described above by taking the lock cylinder hole as an example, and it goes without saying that this structure can also be used to shield other partial structures such as power jacks provided on the mounting panel 23 or the door lock panel.

In order to improve handle 1's stability, establish the cross sectional shape of joint 6 and be the same with the cross sectional shape of second through-hole 14, for example all set up to rectangle or circular, wear to establish behind second through-hole 14 when joint 6, can reduce the range of rocking of handle 1 in the use.

In this embodiment, for further improve handle 1's stability, stop handle 1 and appear rocking in the use, still utilize spacing slider 3 to carry on spacingly to axis of rotation 12. Specifically, the first stopper hole 21 and the second stopper hole 22 are configured to communicate with each other in side surfaces, and the first stopper surface 16 is provided on the side of the rotating shaft 12 close to the second stopper hole 22, as shown in fig. 1, one end of the first stopper surface 16 close to the handle 1 is inclined toward the second stopper 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 slide block 3 close to the first limiting hole 21.

Because the second spacing face 31 and the first spacing face 16 all incline to the right side below in fig. 1, consequently, limiting slide 3 is moving the in-process to handle 1 one side, and the effort between limiting slide 3 and the axis of rotation 12 increases gradually for limiting slide 3 can tightly support on the inner wall of the spacing hole 22 of second simultaneously, makes axis of rotation 12 tightly support on the inner wall of first spacing hole 21 simultaneously, thereby ensures that handle 1 can not appear the phenomenon of rocking in the use. In this embodiment, the first position-limiting surface 16 and the second position-limiting surface 31 are flat surfaces, and in other embodiments, they may be curved surfaces or bent surfaces inclined downward from the right side, and may also serve to fix the rotating shaft 12. The length of the contact between the first stopper surface 16 and the second stopper surface 31 does not exceed the length of the insertion of the card connector 6 into the second through hole 14. Therefore, when the handle 1 needs to be rotated, the reversing block 5 pushes the clamping head 6 out of the second through hole 14, so that the first limiting surface 16 and the second limiting surface 31 can not contact with each other, and the rotation limitation on the rotating shaft 12 is removed.

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

The rotating shaft 12 is rotatably disposed in the first stopper hole 21, and displacement thereof in the axial direction of the first stopper hole 21 is restricted. The left end of axis of rotation 12 passes behind first spacing hole 21 and is in the left side of fixing base 2 to be equipped with location structure 7 at this end, move to the one side of keeping away from fixing base 2 with the restriction handle 1. Specifically, in this embodiment, an external thread is provided at the left end of the rotating 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 can 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 fixing 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. The left end of the limiting slide block 3 is provided with an inwards-sunken spring positioning groove 9, and one end of the reset spring 4, which is far away from the fixed seat 2, is inserted into the spring positioning groove 9. By fixing both sides of the return spring 4, it can be stably operated.
