DETAILED DESCRIPTION

[0023] See attached Figures 1 to 6 The utility model is further described in detail for a door lock that is easy to install.

[0024] A door lock that is easy to install, comprising a base 1 and a cover plate 3, wherein a door lock handle 4 is installed on the base 1, and the cover plate 3 is sleeved on the handle head 41 of the door lock handle 4, and is provided with a cavity 31 adapted to the base 1; at least two hooks 32 are arranged at intervals on the lower end surface of the cover plate 3, and a buckle matching the hooks 32 is arranged on the bottom of the base 1, and at least two through holes 12 for the hooks 32 to penetrate the bottom of the base 1 are provided on the base 1; the hooks 32 pass from the corresponding through holes 12 to the bottom of the base 1 and are hooked on the buckle, thereby locking the cover plate 3 on the base 1;

[0025] When installing the door lock, after completing the installation of the base 1, you only need to press down the cover plate 3 so that the hook 32 on the lower end surface of the cover plate 3 passes through the corresponding hole 12 to the bottom of the base 1, and cooperates with the buckle at the bottom of the base 1 to firmly lock the cover plate 3 on the base 1; the base 1 is built into the cavity 31 of the cover plate 3 as a whole, and there is no need to fix the cover plate 3 with a top screw, which makes the appearance of the door lock more beautiful; at the same time, it simplifies the installation operation of the door lock and improves the installation efficiency.

[0026] The buckle member is a buckle ring 2 installed at the bottom of the base 1, and at least two buckle parts 21 are protruding outward on the buckle ring 2. The buckle parts 21 are arranged below the corresponding holes 12 and can be matched one by one with the hooks 32 after passing through. The inner side surface of the lower end of the hook 32 is obliquely provided with a first guide surface 321, and the inner side surface of the upper end thereof is obliquely provided with a second guide surface 322.

[0027] When installing the cover plate 3, the cover plate 3 is pressed down, and the first guide surface 321 of the hook 32 will press the corresponding buckle portion 21 inwardly, and the hook 32 will slowly move downward under the guidance of the first guide surface 321, and after the hook 32 is passed down, the buckle portion 21 will cooperate with the hook portion of the hook 32 to prevent the hook 32 from detaching from the snap ring 2, and the cover plate 3 is firmly locked on the base 1; wherein the buckle portion 21 of the snap ring 2 has a certain elasticity, and during the process of the hook 32 passing down, the buckle portion 21 will be elastically deformed;

[0028] When the cover plate 3 needs to be removed, it is only necessary to pry the cover plate 3 upward with force, and the hook 32 moves upward under the guidance of the second guide surface 322 and separates from the buckle portion 21, so that the cover plate 3 can be opened. The operation is simple and convenient.

[0029] In order to better lock the cover plate 3 on the base 1 , there are three hooks 32 on the cover plate 3 , and the three hooks 32 are arranged at intervals on the lower end surface of the cover plate 3 ; the three hooks 32 will cooperate with the buckle parts 21 on the snap ring 2 one by one.

[0030] In order to facilitate the installation of the snap ring 2 on the base 1, a mounting portion for installing the snap ring 2 is provided at the bottom of the base 1, and three pairs of limit blocks 13 are provided on the edge of the mounting portion, and each pair of limit blocks 13 is provided at both ends of the corresponding penetration hole 12; the snap ring 2 is placed on the inner side of the three pairs of limit blocks 13, and the buckle portion 21 passes through between each pair of limit blocks 13 and is placed below the penetration hole 12; the inner side of the limit block 13 is provided with a limit groove 131 adapted to the snap ring 2, so that the outer side wall of the snap ring 2 can abut against the limit The snap ring 2 is preferably mounted in the positioning groove 131; when assembling the snap ring 2, it is only necessary to clamp the snap ring 2 in the limiting block 13 and place the buckle portion 21 on the snap ring 2 between each pair of limiting blocks 13, so that the snap ring 2 can be firmly installed in the bottom of the base 1; this simplifies the assembly operation of the snap ring 2 and improves production efficiency; at the same time, placing each buckle portion 21 on the snap ring 2 between each pair of limiting blocks 13 can better limit the buckle portion 21, avoid serious deformation of the buckle portion 21 under the extrusion of the hook 32, and improve the structural strength of the snap ring 2.

[0031] The upper and lower ends of the base 1 are both provided with mounting lugs 11, and two mounting holes 111 are spaced apart on the mounting lugs 11. When installing the base 1, it is only necessary to pass fasteners through the mounting holes 111 and install it on the door panel, so that the base 1 can be firmly fixed on the door panel.

[0032] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
