Referring to fig. 1-7, a screwless mounting case for a building intercom includes a suspension bracket 1 and a main frame case 2 fixed to each other, wherein the suspension bracket 1 is fixedly mounted on a wall surface. The bottom of the suspension bracket 1 is fixedly provided with a buckle 11, a driving gear 21 and a rack slider 22 which are meshed with each other are arranged in the host casing 2 and used for mounting a mounting hole 23 of the buckle 11, and a return spring 24 is arranged at two ends of the host casing 2 and one side of the rack slider 22 respectively, and the other side of the rack slider 22 is opposite to the buckle 11. The driving gear 21 is rotatably connected to the main housing 2 through a driving shaft 25, and one end of the driving shaft 25 is communicated with the outer side wall of the main housing 2.

Further, a pressing block 26 for fixing the driving shaft 25 and the driving gear 21 is fixedly arranged in the main machine housing 2, and the pressing block 26 is locked on the main machine housing 2 through a bolt. A pressing groove 261 is formed in the side wall of the pressing block 26, and the driving shaft 25 and the driving gear 21 are disposed in the pressing groove 261. The top of the indent 261 abuts against the driving shaft 25, so that two ends of the driving shaft 25 are limited by the host casing 2 and the indent 261 respectively, and the fixed axial direction of the driving shaft 25 is realized.

Specifically, the driving shaft 25 includes a fixing portion 251, a gear connecting portion 252, and a limiting portion 253, which are connected in sequence, and the cross-sectional areas of the fixing portion 251, the gear connecting portion 252, and the limiting portion 253 are sequentially reduced. The fixing portion 251 is rotatably connected to the main housing 2, specifically, a positioning member 29 corresponding to a side wall of the fixing portion 251 is disposed on the main housing 2, and the fixing portion 251 of the driving shaft 25 is rotatably disposed in the positioning member 29. The driving gear 21 is fixedly connected to the gear connecting portion 252, and the gear connecting portion 252 may be formed in a non-circular cross-section so that the driving gear 21 does not rotate relative to the gear connecting portion. A shaft shoulder 254 is formed at the joint of the gear connecting portion 252 and the limiting portion 253, and the press groove 261 is abutted to the shaft shoulder 254. At this time, the fixing portion 251 of the driving shaft 25 is restricted by the positioning member 29 and the inner side surface of the main body casing 2, the restricting portion 253 of the driving shaft 25 is restricted by the pressing block 26, and the driving shaft 25 can rotate only in the casing.

In this embodiment, the main housing 2 is provided with a sliding groove 27, and the rack slider 22 is movably disposed in the sliding groove 27 to guide and limit the moving direction of the rack slider 22.

Preferably, the sliding groove 27 is further provided with a first limiting groove 271 corresponding to the limiting portion 253, the pressing block 26 is further provided with a second limiting groove 262 corresponding to the limiting portion 253, the first limiting groove 271 and the second limiting groove 262 are oppositely opened, and the limiting portion 253 is circumferentially limited from two sides, so that the positioning is more reliable, and the deviation of the middle shaft during installation and use is avoided.

Preferably, a limiting block 221 extends downwards from the bottom of the rack slider 22, when the limiting block 221 abuts against the side wall of the positioning member 29, the rack slider 22 is engaged with the buckle 11, and the rack slider 22 is limited. In this scheme, in order to guarantee the connection reliability, return spring 24 is compression state all the time, and in order to avoid when fixed state rack slide 22 right buckle 11 forms too big pressure and causes wearing and tearing, it can just to guarantee the block state through stopper 221 and setting element 29's cooperation messenger.

Further, the buckle 11 includes an abutting portion 111 and a first clamping portion 112 circumferentially extending from the abutting portion 111, and the rack slider 22 is provided with a second clamping portion 222 opposite to the first clamping portion 112. When the suspension bracket is fixed, the side wall of the rack slider 22 abuts against the abutting part 111, the bottom surface of the first clamping part 112 abuts against the top surface of the second clamping part 222, and at this time, the suspension bracket 1 is fixedly connected with the host casing 2. In this embodiment, the buckle 11 is a pin.

Preferably, the first clamping portion 112 is in a circular truncated cone shape, and the diameter of the top of the first clamping portion 112 is smaller than that of the bottom of the first clamping portion to form an inclined side wall; the side wall of the second clamping portion 222 close to the buckle 11 is provided with an inclined surface corresponding to the side wall of the circular truncated cone.

Preferably, referring to fig. 4-5, an adjusting hole 2511 is disposed at one end of the fixing portion 251 connected to the main machine housing 2, the adjusting hole 2511 has a non-circular cross-section, and a through hole 28 corresponding to the adjusting hole 2511 is disposed on the main machine housing 2. When the suspension bracket is used, a corresponding tool can penetrate through the through hole 28 to be matched with the adjusting hole 2511, so that the driving shaft 25 and the driving gear 21 can be rotated, the rack sliding block 22 is driven to horizontally move, and the suspension bracket 1 and the host machine shell 2 can be conveniently detached and installed.

The working principle is as follows:

during installation, the buckle 11 penetrates through the installation hole 23, at this time, the side wall of the first clamping portion 112 abuts against the side wall of the second clamping portion 222, and along with the upward movement of the first clamping portion 112, the rack slider 22 forms horizontal linear movement through the inclined plane matching, so that the rack slider 22 is driven to horizontally move in the direction away from the installation hole 23, and the return spring 24 is in a compressed state; when the first clamping portion 112 continuously moves upward to be separated from the second clamping portion 222, the rack slider 22 moves toward the direction close to the mounting hole 23 under the action of the return spring 24 until being clamped with the buckle 11, and the suspension bracket 1 and the host casing 2 are fixed.

During disassembly, an adjusting tool corresponding to the adjusting hole 2511 penetrates through the through hole 28 to rotate the driving gear 21, so that the rack slider 22 is driven to move towards the direction far away from the buckle 11, and at the moment, the suspension bracket 1 and the host machine shell 2 can be separated.

According to the scheme, an external bolt is not needed for connection, disassembly and assembly can be realized only by the hidden gear rack structure and the corresponding reset spring, and compared with the traditional screw fixation, the novel screw fixing device is more convenient to use, convenient to install, simple to operate and capable of improving the machining efficiency; meanwhile, the safety performance can be effectively improved, and malicious disassembly by other people is prevented.

Referring to fig. 6-7, an installation piece 12 for installing the buckle 11 is arranged on the suspension bracket 1, a buffer piece 13 is arranged on the installation piece 12, and after installation, the buffer piece 13 is positioned between the connection part of the suspension bracket 1 and the host casing 2, so that the structural buffer performance of the connection part is improved, and the structural safety is improved; meanwhile, in this embodiment, the buffer sheet 13 is made of foam, which effectively improves the waterproof performance and connection reliability of the joint between the suspension bracket 1 and the host casing 2.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
