Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0029] Embodiment 1:

[0030] This embodiment provides a door lock with an easily detachable handle, comprising:

[0031] Two installation panels 1, the two installation panels 1 are facing each other;

[0032] A lock core 2 is installed between two installation panels 1;

[0033] Two limiting members 3 are respectively arranged on the two mounting panels 1, and the limiting members 3 include a connecting rod 31 rotatably connected to the mounting panel 1 and a limiting rod axially arranged at one end of the connecting rod 31;

[0034] Two handles 4 are respectively mounted on the two limit rods;

[0035] Among them, the handle 4 includes a first clamping portion 41 and a second clamping portion 42, one end of the first clamping portion 41 and the second clamping portion 42 are hinged to each other, and a clamping groove 5 is provided on the other end, the two clamping grooves 5 are opposite to each other, and a clamping hole 6 adapted to the shape of the limiting rod is formed between the two clamping grooves 5, the handle 4 is clamped on the limiting rod through the clamping hole 6, and the first clamping portion 41 and the second clamping portion 42 are connected to each other at one end close to the clamping hole 6 by a fastening assembly 7, an elastic member 8 for opening the clamping hole 6 is provided between the first clamping portion 41 and the second clamping portion 42, and limiting portions 9 for limiting the handle 4 are respectively provided at both ends of the limiting rod.

[0036] In the technical solution, the lock core 2 can be a conventional lock core 2, for example, a lock core 2 that is inserted with a key to open and lock the door. The lock core 2 is installed inside the door panel, and the two mounting panels 1 are respectively installed on the front and rear sides of the door panel using screws. By turning the handle 4, the lock tongue on the lock core 2 can be extended and retracted, thereby closing and opening the door.

[0037] The connecting rod 31 can keep a certain distance between the handle 4 and the door panel, so that the fingers can grasp the handle 4. The connecting rod 31 of the limiter 3 is rotatably connected to the mounting panel 1. The connecting rod 31 of the limiter 3 can be provided with a square hole so that the rod-shaped square core on the lock core 2 can be inserted into the square hole. When the handle 4 is turned, the connecting rod 31 is driven to rotate, thereby driving the lock tongue of the lock core 2 to extend and retract, so as to close and open the door.

[0038] The middle part of the handle 4 is used for gripping, that is, the middle part and gripping of the first clamping part 41 and the second clamping part 42. The cross section of the handle 4 can be circular to facilitate gripping. Therefore, the cross sections of the first clamping part 41 and the second clamping part 42 can both be semicircular, and therefore, a plane can be set on each of the first clamping part 41 and the second clamping part 42, and the two planes conflict with each other.

[0039] The first clamping portion 41 and one end of the second clamping portion 42 can be hinged by setting a hinge rod, so that the first clamping portion 41 can rotate relative to the second clamping portion 42, thereby realizing the opening and closing of the handle 4, and when the door lock is installed on the door panel, the steps of assembling the handle 4 can be reduced.

[0040] The limiting rod on the limiting member 3 can be welded to the connecting rod 31 , and the cross section of the limiting rod can be square, triangular or hexagonal. The limiting rod is used to prevent the handle 4 from rotating on the limiting member 3 .

[0041] The two clamping grooves 5 are opposite to each other, and the clamping grooves 5 pass through both sides of the first clamping portion 41 and the second clamping portion 42, and a clamping hole 6 adapted to the shape of the limiting rod is formed between the two clamping grooves 5. After the handle 4 is clamped on the limiting rod through the clamping hole 6, the handle 4 is prevented from rotating on the limiting member 3.

[0042] After the handle 4 is clamped on the limit rod through the clamping hole 6, the first clamping part 41 and the second clamping part 42 are fastened by the fastening assembly 7 to prevent the handle 4 from opening. The fastening assembly 7 can be a screw to facilitate the installation and removal of the handle 4.

[0043] The elastic member 8 may be a spring or a spring disposed between the first clamping portion 41 and the second clamping portion 42. The elastic member 8 is elastic. After the fastening assembly 7 is removed, the handle 4 can be opened by the rebound effect of the elastic member 8, so that the limit rod is separated from the clamping hole 6. Therefore, after the fastening assembly 7 is removed, there is no need to manually open the handle 4 to separate the limit rod from the clamping hole 6, thereby further improving the removal speed.

[0044] The two limiting portions 9 respectively abut against the front and rear sides of the handle 4 to limit the first clamping portion 41 and the second clamping portion 42 of the handle 4 to prevent the first clamping portion 41 and the second clamping portion 42 from moving forward and backward.

[0045] To summarize, in this embodiment, the handle 4 is clamped on the limiting rod through the clamping hole 6 formed between the first clamping portion 41 and the second clamping portion 42, and the first clamping portion 41 and the second clamping portion 42 are fixed together by the fastening assembly 7, thereby achieving the effect of facilitating the installation and removal of the door lock handle 4, and improving the speed of installing and removing the handle 4. The handle 4 can be opened by the rebound effect of the elastic member 8. After removing the fastening assembly 7, there is no need to manually open the handle 4, which further improves the removal speed of the handle 4.

[0046] Conventional handles 4 are L-shaped, and are usually installed on the mounting panel 1 before being transported and sold, taking up space during storage. By clamping the handle 4 on the limit rod, in addition to facilitating installation and removal, the handle 4 is separated from the mounting panel 1, which is also conducive to reducing the space occupied during storage.
