Description

Technical Field

[0001] The utility model relates to the technical field of door locks, and more specifically, to an installation structure of a handle lock. Background Art

[0002] A door lock is a commonly used door protection device to prevent unauthorized entry of people outside the door. A handle lock drives a square shaft to rotate to drive the lock tongue in the lock body to contract, so as to realize the opening of the door lock; generally, a handle lock includes a mounting base, a split ring covering the mounting base, and a handle, wherein the handle is rotatably arranged on the mounting base to realize the opening operation of the door lock.

[0003] For example, the Chinese patent with the publication number of CN205976741U discloses a split lock, including a lock body, at least two fasteners, a handle assembly and a lock core assembly.

The fastening post passes through the lock body, and the screw can be screwed into the internal threaded hole. The handle assembly includes a handle, a handle outer retaining ring and a handle inner retaining ring. The number of the handle, the handle outer retaining ring and the handle inner retaining ring is two. The two handles are respectively arranged on both sides of the lock body. One handle corresponds to one handle outer retaining ring and one handle inner retaining ring; the handle outer retaining ring covers the handle inner retaining ring, and the lock core outer retaining ring covers the lock core inner retaining ring to prevent the screw from being exposed; however, the handle of this door lock is installed through the inner retaining ring and the outer retaining ring, and the inner retaining ring and the outer retaining ring protrude from the door panel, so that the overall structure of the door lock is relatively complex, resulting in the appearance of the door lock not being concise enough.

Specific embodiments

[0023] Refer to the attached Figures 1 to 6 A further detailed description is given to an installation structure of a handle lock of the present utility model.

[0024] An installation structure of a handle lock includes a base 1 and a decorative plate 2 embedded in a door panel, wherein the color pattern on the outer surface of the decorative plate 2 is consistent with that of the door panel, making the door lock more adaptable to the door leaf; the decorative plate 2 is fixed to the base 1 through a mounting base 3, a through hole 31 for the square shaft sleeve 41 on the handle 4 to pass through is provided in the middle of the mounting base 3, one end of the square shaft sleeve 41 is connected to the handle head of the handle 4, and the other end passes through the through hole 31 and is connected to the square shaft 5;

[0025] A mounting hole 11 adapted to the mounting base 3 is opened in the middle of the base 1, and a first card slot 111 is provided on the inner side wall of the mounting hole 11; a block 32 adapted to the first card slot 111 is provided on the outer side wall of the mounting base 3, and a flange 33 protrudes outward from its upper end; an assembly hole 21 adapted to the mounting base 3 is opened in the middle of the decorative plate 2, and a groove 23 adapted to the block 32 is provided on the hole wall of the assembly hole 21; the decorative plate 2 is sleeved on the mounting base 3 through the assembly hole 21, and the upper end surface of the decorative plate 2 abuts against the flange 33; the mounting base 3 assembled with the decorative plate 2 is fixedly installed in the mounting hole 11 of the base 1 through the cooperation of the block 32 and the first card slot 111;

[0026] When installing the decorative plate 2, only need to align the clamping block 32 sleeved with the base 1 of the decorative plate 2 with the corresponding first card slot 111, and then insert it into the mounting hole 11. The clamping block 32 and the first card slot 111 cooperate to fix the mounting seat 3 sleeved with the decorative plate 2 on the mounting hole 11 of the base 1. The lower end surface of the decorative plate 2 is closely attached to the door panel, and the base 1 for installing the handle 4 is hidden inside the door panel. After the installation of the base 1 and the decorative plate 2 is completed, only need to pass the handle 4 connected with the square shaft 5 through the through hole 31 and connect it with the handle 4 on the other side of the door panel. Only the thin decorative plate 2 and the handle 4 are visible outside the door panel, making the appearance of the door lock more simple and generous. At the same time, the structure of the door lock is simpler, reducing the production cost.

[0027] The upper end surface of the decorative plate 2 is recessed downward with a second card slot 22 adapted to the flange 33. The flange 33 is placed in the groove 23, so that the mounting seat 3 and the decorative plate 2 are better matched, avoiding the flange 33 of the mounting seat 3 protruding outside the decorative plate 2 and making the appearance of the door lock more beautiful.

[0028] In order to make the mounting seat 3 sleeved with the decorative plate 2 better cooperate with the base 1, the number of the first card slots 111 is two, and the two first card slots 111 are arranged at intervals on the inner side wall of the mounting hole 11. The two clamping blocks 32 arranged at intervals on the outer side wall of the mounting seat 3 are arranged corresponding to the two first card slots 111 one by one. The cooperation of the two clamping blocks 32 and the first card slots 111 fixes the mounting seat 3 on the base 1 more firmly. At the same time, the decorative plate 2 is provided with second card slots 22 corresponding to the two clamping blocks 32, so that the decorative plate 2 is clamped on the mounting seat 3.

[0029] Two screw holes 12 are provided at both ends of the base 1. The base 1 is fixed on the door panel by fasteners passing through the screw holes 12, so that the base 1 can be firmly embedded in the door panel.
