Description

Technical Field

[0001] The utility model relates to the technical field of intelligent intercom equipment, in particular to an intelligent intercom terminal which is easy to install and disassemble and can be prevented from being disassembled. Background Art

[0002] Smart home products are one of the fastest growing fields in recent years. With the continuous improvement and popularization of technology, people have higher and higher requirements for smart home devices and smart building equipment (such as building intercom terminals), and product design is more aesthetic and fashionable. In an era of soaring labor costs, it is particularly important to require building intercom terminals to be easy to install, disassemble and maintain, and the product is required to have a certain anti-dismantling function. There are two common ways to install building intercom terminals on the market: 1. Set 2 to 4 gourd-shaped holes / hooks on the bracket, slide down into the "T" screw / hook slot on the back shell of the host, and there is a 90° bent tongue at the bottom of the bracket (with a screw hole in the middle) that fits the screw hole at the bottom of the host, and then lock the anti-dismantling screws to prevent the host from moving upward and falling or detaching; 2. The two hooks at the top of the bracket are inserted into the two hook slots on the top of the host. The host uses these two hooks as the rotation center and rotates downward to the wall. There is a 90° bent tongue at the bottom of the bracket (with a screw hole in the middle) that fits the screw hole at the bottom of the host, and then the anti-dismantling screws are locked to prevent the host from flipping over and falling or detaching.

[0003] The above two installation methods have one thing in common, that is, they both require screwing. Their disadvantages are: 1. In concentrated residential areas or office buildings, there are many installations, and some entrance areas are small, with little space for movement. In addition, the screw position is usually set at the bottom (not visible from the front), and the installer must bend down and turn his head 180 degrees to align the screw hole to screw the screw, which brings great work intensity and difficulty to the installer; 2. The anti-disassembly relies on the "hexagonal" or "torx with column" shape of the bottom screw head, that is, a conventional screwdriver ("one" or "cross") may not be able to unscrew it, but there is still a problem of low anti-disassembly difficulty, because it is very easy to obtain "hexagonal" or "torx with column" screwdrivers on the market; 3. The locking structure of existing products is designed on the back shell, so the device can only be installed by floating it on the wall but cannot be embedded in the wall (if the back shell is embedded in the wall, it cannot be unlocked), and the installation scenario is limited.

[0004] In view of this, it is urgent to study a smart intercom device that can be easily installed, easy to disassemble and anti-theft. Utility Model Content

[0057] Preferably, the hanger 2 is fixed to the wall-embedded box 3 by a second fixing screw.

[0058] The working principle of the utility model is as follows:

[0059] The process of locking the host 1 on the wall is as follows: install the bracket 2 into the wall box 3 in advance, and install the rear shell 15 of the host 1 into the front shell 11. Then, the trumpet-shaped groove 112 on the back of the front shell 11 of the host 1 is buckled into the hooks 25 of the tongues 21 extending on the left and right sides of the top of the bracket 2 at a certain angle, and the host 1 is pressed downward to rotate (or naturally lower) the host 1 to the two bent inserts 23 in the middle of the bottom of the bracket 2. After the bent bevel contacts the end of the telescopic shaft 143, as the host 1 is pressed, the bent bevel pushes the telescopic shaft 143 to move outward, and the compression spring 144 is compressed. When the host 1 rotates to a position close to the wall (i.e., the pin hole 22 moves to a position aligned with the telescopic shaft 143), the telescopic shaft 143 is inserted into the pin holes 22 of the two bent inserts 23 in the middle of the bottom end of the bracket 2 under the action of the compression spring 144. At this time, the upper end of the host 1 is hung on the bracket 2, and the telescopic shaft 143 at the lower end is inserted into the pin hole 22 of the bracket 2. At the same time, the raised bridge rib 24 in the upper and middle part of the bracket 2 just hits the silicone button 16 on the rear shell 15 of the host 1, triggering the on-state of the travel switch 121 on the mainboard 12. The mainboard 12 sends a signal, and the host 1 is in a safe state for wall hanging, and the fixation is completed.

[0060] Host 1 disassembled and unlocked status:

[0061] The first disassembly method: insert the straight rod head 41 of the Y-shaped disassembly key 4 into the V-shaped lock hole 113 at the bottom of the host 1 and move upward, driving the slider 142 and the telescopic shaft 143 to move outward, and the telescopic shaft 143 is disengaged from the pin hole 22 of the bracket 2. At this time, the host 1 is rotated and flipped up, and moved upward. The host 1 is disengaged from the protruding tongues 21 on the left and right sides of the top of the bracket 2 and the hooks 25. At the same time, the raised bridge ribs 24 in the upper and middle part of the bracket 2 are disengaged from the silicone button 16 on the rear shell 15 of the host 1, and the travel switch 121 of the mainboard 12 is triggered to turn to the closed state. The mainboard 12 sends a signal, and the host 1 is in a wall-mounted detached state, and the disassembly is completed.

[0062] The second disassembly method: insert the double fork tail 42 of the Y-shaped disassembly key 4 into the two square lock holes 114 at the bottom of the host 1 and move upward, driving the slider 142 and the telescopic shaft 143 to move outward. The telescopic shaft 143 is disengaged from the pin hole 22 of the bracket 2. At this time, the host 1 is rotated and flipped up, and moved upward. The host 1 is disengaged from the tongue pieces 21 on the left and right sides of the top of the bracket 2 and the hooks 25. At the same time, the raised bridge ribs 24 in the upper middle part of the bracket 2 are disengaged from the silicone button 16 on the rear shell 15 of the host 1, triggering the mainboard 12 travel switch 121 to the closed state, and the mainboard 12 sends a signal. The host 1 is in the wall-mounted detached state, and the disassembly is completed.

[0063] The entire installation and disassembly operation mechanism of the utility model is designed on the front shell 11, and it can be realized whether it is embedded in the wall or floating on the wall, without being limited by the scene. The utility model device does not need to screw in and out when installing the host 1, especially when the installation space is limited, outdoor batch installation, and the installation strength is high, it can greatly improve the installation efficiency and reduce the work intensity and difficulty. When installing the host 1, you only need to hang it, rotate it naturally, press the bottom, hear a click, and the installation is complete. The whole process does not require external screws to cooperate, which is convenient and fast. In addition, the utility model adopts a "Y"-shaped key, which is not available on the market, and the host 1 has a wall-mounted mechanical induction push-button travel switch that is superimposed and used to feedback the status of the host 1, further enhancing the anti-disassembly and anti-theft properties and avoiding the problem of weak anti-theft.
