[0005] To achieve the above-mentioned purpose, the utility model provides a door opening alarm device for communication equipment, comprising: a communication box body with an open front surface; a box door movably connected to the front surface of the communication box body by hinges, and the box door is limited to its open state by a support mechanism arranged in the communication box body; two cylindrical locks symmetrically arranged at the bottom of one side of the box door; a buzzer installed through the top of one side of the box door; a terminal block fixedly installed at the top of one side of the inner wall of the communication box; and two micro switches symmetrically fixedly installed at the bottom of one side of the inner wall of the communication box and cooperating with the lock tongues of the cylindrical locks; the buzzer, the terminal block and the micro switch are electrically connected by wires.

[0006] Furthermore, the support mechanism includes two support rods symmetrically and movably connected on both sides of the inner wall of the communication box, two brackets symmetrically fixedly installed on the other side of the box door and in an inverted L shape, and a locking component provided on the bracket for locking the position of the support rods.

[0007] The locking component includes a limit rod rotatably connected to the surface of one end of the support rod, a boss block fixedly connected to the end surface of the limit rod, a sliding groove opened on the surface of the vertical section of the bracket and slidably connected to the limit rod, and a limiting notch opened on one side of the inner wall of the sliding groove and clamped with the limit rod.

[0022] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0023] Example 1

[0024] Reference Figure 1-6 As shown, a door opening alarm device for communication equipment includes: a communication box 1 with an open front surface; a box door 2 movably connected to the front surface of the communication box 1 by a hinge, and the box door 2 is limited to its open state by a supporting mechanism arranged in the communication box 1; two cylindrical locks 3 symmetrically arranged at the bottom of one side of the box door 2; a buzzer 4 installed through the top of one side of the box door 2; a terminal block 5 fixedly installed at the top of one side of the inner wall of the communication box 1; and two micro switches 6 symmetrically fixedly installed at the bottom of one side of the inner wall of the communication box 1 and cooperating with the lock tongues of the cylindrical lock 3; the buzzer 4, the terminal block 5 and the micro switch 6 are electrically connected by wires.

[0025] The technical solution provided by this embodiment is as follows: when in use, by installing the communication box body 1 in the designated use position, when the communication box body 1 is maintained and constructed, the power to the communication box body 1 is cut off, and then the cylinder lock 3 is rotated to rotate the lock tongue to open the box door 2. At this time, the lock tongue of the cylinder lock 3 is separated from the roller of the micro switch 6, so that the contacts of the micro switch 6 are closed and in the original state (unpowered operating state). After the construction and maintenance are completed and the power is turned on, the box door 2 is in the open state, and the contacts of the micro switch 6 are closed, and the buzzer 4 works to issue an alarm reminder. When the personnel closes the box door 2, the lock tongues of the two cylindrical locks 3 rotate into place, so that the lock tongues press the rollers of the microswitch 6, and the contacts are disconnected to stop the buzzer 4. Therefore, the cylindrical lock 3 is used to control the on and off of the microswitch 6, thereby controlling the opening and closing state (ON / OFF) of the buzzer 4 to achieve real-time feedback on the opening and closing state of the box door 2, so as to remind workers to close the door, thereby reducing the phenomenon of missing the door during construction, ensuring the sealing performance and safety performance of the communication box body 1, and effectively improving the safety and service life of the communication box body 1.

[0026] Preferably: the support mechanism includes two support rods 7 symmetrically and movably connected on both sides of the inner wall of the communication box 1, two brackets 8 symmetrically fixedly installed on the other side of the box door 2 and in an inverted L shape, and a locking component provided on the bracket 8 for locking the position of the support rod 7.

[0027] The locking component includes a limit rod 9 rotatably connected to the surface of one end of the support rod 7, a boss block 10 fixedly connected to one end surface of the limit rod 9, a slide groove 11 opened on the surface of the vertical section of the bracket 8 and slidingly connected to the limit rod 9, and a limit groove 12 opened on one side of the inner wall of the slide groove 11 and clamped with the limit rod 9, wherein the diameter of the boss block 10 is larger than the diameter of the limit rod 9 to prevent the limit rod 9 from detaching from the slide groove 11.

[0028] Specifically, when opening the door 2, the cylindrical lock 3 is opened and then rotated upward to open the door 2. During the process, the support rod 7 can rotate with the rotation of the door 2 and drive the limit rod 9 to slide along the slide groove 11. When the door 2 is opened, the limit rod 9 is aligned with the limit slot 12 by adjusting the position, and at the same time, it is inserted into the limit slot 12 to limit and lock the support rod 7, so that the support rod 7 supports the door 2 in an inclined state. When closing the door 2, it can be rotated to close by separating the limit rod 9 from the limit slot 12, and the door 2 can be locked by the cylindrical lock 3.

[0029] Preferably, two groups of cable glands 13 are fixedly installed on the bottom of the communication box 1 , and each group of cable glands 13 is evenly distributed in a linear array. A sealing gasket 14 is fixedly installed on a side of the box door 2 close to the communication box 1 .

[0030] Specifically, by setting the gland head 13, the cable is facilitated to access the inside of the communication box 1, the fastening of the cable is facilitated, the friction and wear of the cable at the access hole are reduced, and the sealing and waterproof performance between the cable and the access hole are improved. By setting the sealing gasket 14, the sealing effect between the box door 2 and the communication box 1 is improved, and the safety hazard caused by the moisture entering the inside of the communication box 1 is avoided.

[0031] Embodiment two

[0032] Based on the embodiment one, in the embodiment, the inside of the communication box 1 is provided with a heat dissipation mechanism, and the heat dissipation mechanism is used for cooling the inside of the communication box 1.

[0033] The heat dissipation mechanism comprises a heat dissipation fan 15 fixedly installed at the top of the communication box 1, a ventilation slot opening in one side surface of the communication box 1, and a dust screen 16 fixedly installed in the ventilation slot. In order to prevent rainwater from entering the inside of the communication box 1 through the dust screen 16, a rain cover can be installed outside the dust screen 16, or a waterproof and breathable film is installed in the ventilation slot, and then the dust screen 16 is installed. The specific protection measures are the prior art known in the art, and will not be described in detail here.

[0034] The technical scheme provided in the embodiment is that: in the running process of the communication box 1, the heat dissipation fan 15 is started to make the heat in the communication box 1 discharged outward, and the air is inhaled through the ventilation slot, so that the air in the communication box 1 is circulated to achieve the effect of heat dissipation and cooling. At the same time, the dust and impurities in the air are filtered by the ventilation slot cooperating with the dust screen 16, so that the dust and impurities are prevented from entering the communication box 1 to affect the use of the internal electrical elements, and the use effect of the communication box 1 is improved.

[0035] The above only discloses the preferred embodiments of the utility model, and of course cannot limit the scope of the utility model, so equivalent changes made according to the utility model claims still belong to the scope covered by the utility model.
