This eliminates the cumbersome operation of fixing with screws and improves the efficiency of maintenance and repair of the signal transmission box.

Description

Technical Field

[0001] The utility model relates to the technical field of fire signal transmission, and in particular to an Internet of Things signal transmission device for a fire system. Background Art

[0002] "IoT Intelligent Firefighting" utilizes IoT high-tech + new chemical materials to digitally collect and monitor information such as firefighting equipment in real time, realizing centralized and unified management of firefighting resources, and using the "IoT Intelligent Firefighting System" to integrate relevant resource data such as fire risk hazard investigation and automatic alarm system and firefighting IoT management platform data, real-time monitoring of firefighting facility status, and real-time perception and status visualization intelligent monitoring of firefighting facilities, achieving the intelligent management goal of dynamic monitoring, analysis, and active early warning of fire hazards.

[0003] During use, the IoT signal transmission box needs to be regularly maintained and inspected to ensure the normal operation of the IoT signal transmission device. The IoT signal transmission box in the prior art is usually fixed at a higher position by screws and other fixings to facilitate signal transmission. During disassembly and maintenance, the staff needs to install or disassemble by screwing multiple screws, which is cumbersome and inconvenient, reducing the inspection efficiency of the IoT signal transmission box. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an Internet of Things signal transmission device for a fire protection system.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A fire protection system Internet of Things signal transmission device, including a fixing plate fixed to a wall, a support base fixed to the side wall of the fixing plate away from the wall, a signal transmission box arranged on the upper surface of the support base, a slot arranged at the intersection between the upper surface of the support base and the side wall of the support base, an insert block plug-inly matched with the slot fixed to the bottom of the signal transmission box, and a limit assembly for limiting the position of the insert block installed on the support base.

[0007] By adopting the above technical solution, the plug-in block is inserted into the slot and the plug-in block is limited by the limiting component, so that the plug-in block and the signal transmission box are fixed on the support seat. When the signal transmission box needs to be disassembled, the staff only needs to release the limiting effect of the limiting component on the plug-in block, thereby removing the plug-in block from the slot, eliminating the tedious operation of fixing with screws, and improving the efficiency of maintenance and repair of the signal transmission box.

[0008] Furthermore, a fixing groove is provided at the bottom of the support seat, and a limiting groove is provided at the bottom of the insertion block. The limiting assembly includes a limiting rod that passes through the bottom of the support seat and is slidably connected, a pulling block fixed to the lower end of the limiting rod, and a clamping spring that is arranged in the fixing groove and sleeved on the limiting rod. The upper end of the clamping spring is fixed to the top wall in the fixing groove, and the lower end of the clamping spring is fixed to the upper surface of the pulling block, and the limiting rod is plugged into and matched with the limiting groove.

[0009] By adopting the above technical solution, the pulling block drives the limit rod to maintain the plug-in state with the limit slot under the elastic force of the clamping spring, thereby limiting the plug-in block in the slot. When the signal transmission box needs to be disassembled, the staff pulls the limit rod downward through the pulling block to make the limit rod disengage from the limit slot and enter the support seat, thereby removing the plug-in block from the slot, making it easier to install or disassemble the signal transmission box.

[0010] Furthermore, the cross-sections of the insert block and the slot are both dovetail-shaped.

[0011] By adopting the above technical solution, the dovetail-shaped cross-section of the plug-in block and the slot prevents the plug-in block from escaping upward from the slot, thereby improving the stability of the fit between the plug-in block and the slot.

[0012] Furthermore, the side wall of the limiting rod is provided with a yielding inclined surface which cooperates with the side wall of the insert block.

[0013] By adopting the above technical solution and opening the inclined surface, the plug block can be inserted into the slot by the inclined surface to squeeze the limit rod downward into the support seat. After the plug block is fully inserted into the slot, the limit rod is upwardly engaged with the limit groove under the elastic force of the clamping spring, thereby limiting the plug block, eliminating the tedious operation of the staff to manually pull the limit rod, and facilitating the rapid installation of the signal transmission box.

[0014] Furthermore, an extension rope is fixed to the bottom of the pulling block.

[0015] By adopting the above technical solution and setting the extension rope, it is convenient for the staff to pull the pulling block through the extension rope, so as to facilitate the disassembly of the signal transmission box.

[0016] Furthermore, a rubber pad is fixed to the bottom of the signal transmission box.

[0017] By adopting the above technical solution, the rubber pad is made of rubber material, and its surface has a large friction coefficient. The bottom of the signal transmission box cooperates with and presses against the rubber pad on the upper surface of the support seat, thereby increasing the friction between the bottom of the signal transmission box and the upper surface of the support seat and enhancing the stability of the signal transmission box.

[0018] Furthermore, an oblique support rod is fixed to the side wall of the fixing plate, and the upper end of the oblique support rod is fixed to the bottom of the support seat.

[0019] By adopting the above technical solution, the oblique support rod supports and reinforces the bottom of the support seat, thereby enhancing the stability of the support seat.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In the present application, the plug-in block is inserted into the slot and the plug-in block is limited by the limit assembly, so that the plug-in block and the signal transmission box are fixed on the support seat. When the signal transmission box needs to be disassembled, the staff only needs to release the limit effect of the limit assembly on the plug-in block, so as to remove the plug-in block from the slot, eliminating the tedious operation of fixing with screws, thereby improving the efficiency of maintenance and repair of the signal transmission box;

[0022] 2. In the present application, the pull block drives the limit rod to maintain the plug-in state with the limit slot under the elastic force of the tightening spring, so that the plug block is limited in the slot. When the signal transmission box needs to be disassembled, the staff pulls the limit rod downward through the pull block, so that the limit rod is separated from the limit slot and enters the support seat, so that the plug block is taken out of the slot, which is convenient for installing or disassembling the signal transmission box.

[0023] 3. In the present application, the opening of the inclined surface allows the block to press the limit rod downward into the support seat through the inclined surface during the insertion of the block into the slot. After the block is fully inserted into the slot, the limit rod is inserted and matched with the limit groove under the elastic force of the clamping spring, thereby limiting the block, eliminating the tedious operation of the staff to manually pull the limit rod, and facilitating the rapid installation of the signal transmission box.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0028] like Figure 1 and Figure 2 As shown, an embodiment of the present application discloses an Internet of Things signal transmission device for a fire protection system, including a fixing plate 1, a support seat 2, a signal transmission box 3, an insert block 4 and a limit assembly 5.

[0029] The fixing plate 1 is a rectangular plate-like structure, and the fixing plate 1 is fixed on the wall. The support seat 2 is a rectangular parallelepiped structure, and the support seat 2 is fixed on the side wall of the fixing plate 1 away from the wall. A slot 21 is provided at the intersection between the upper surface of the support seat 2 and the side wall of the support seat 2, and a fixing slot 22 is provided at the bottom of the support seat 2, and the cross section of the slot 21 is dovetail-shaped. The signal transmission box 3 is a signal transmission box 3 commonly used in the prior art and suitable for this embodiment, and the signal transmission box 3 is arranged on the upper surface of the support seat 2. The plug block 4 is a block structure with a dovetail-shaped cross section, and the plug block 4 is fixed to the bottom of the signal transmission box 3. The plug block 4 is plugged into and matched with the slot 21, and a limiting slot 41 is provided at the bottom of the plug block 4.

[0030] The limit assembly 5 is installed on the support seat 2 and is used to limit the insertion block 4. The limit assembly 5 includes a limit rod 51, a pulling block 52 and a tightening spring 53. The limit rod 51 is a vertically arranged rectangular rod-shaped structure. The limit rod 51 is arranged through the bottom of the support seat 2 and is slidably connected. The limit rod 51 is plugged into the limit groove 41. The pulling block 52 is a round block-shaped structure. The pulling block 52 is fixed to the lower end of the limit rod 51. The tightening spring 53 is arranged in the fixing groove 22. The tightening spring 53 is sleeved on the limit rod 51. The upper end of the tightening spring 53 is fixed to the inner top wall of the fixing groove 22, and the lower end of the tightening spring 53 is fixed to the upper surface of the pulling block 52.

[0031] The dovetail-shaped cross-section of the plug block 4 and the slot 21 prevents the plug block 4 from escaping from the slot 21 upwards, thereby improving the stability of the cooperation between the plug block 4 and the slot 21. The plug block 4 is inserted into the slot 21, and the pulling block 52 drives the limit rod 51 to maintain the plug-in state with the limit groove 41 under the elastic force of the tightening spring 53, so that the plug block 4 is limited in the slot 21, thereby fixing the plug block 4 and the signal transmission box 3 on the support seat 2. When the signal transmission box 3 needs to be disassembled, the staff only needs to pull the limit rod 51 downward by pulling the block 52, so that the limit rod 51 is separated from the limit groove 41 and enters the support seat 2, thereby removing the plug block 4 from the slot 21, eliminating the tedious operation of fixing with screws, and improving the efficiency of maintenance and repair of the signal transmission box 3.

[0032] In order to facilitate the rapid installation of the signal transmission box 3, the side wall of the limit rod 51 is provided with a yielding inclined surface 511 which cooperates with the side wall of the plug block 4. The provision of the yielding inclined surface 511 allows the plug block 4 to press the limit rod 51 downward into the support seat 2 through the yielding inclined surface 511 during the process of inserting the plug block 4 into the slot 21. After the plug block 4 is fully inserted into the slot 21, the limit rod 51 is upwardly plugged into the limit groove 41 under the elastic force of the clamping spring 53, thereby limiting the plug block 4, eliminating the tedious operation of the staff manually pulling the limit rod 51, thereby facilitating the rapid installation of the signal transmission box 3.

[0033] In order to facilitate the disassembly of the signal transmission box 3, an extension rope 6 is fixed to the bottom of the pulling block 52. The provision of the extension rope 6 makes it convenient for the staff to pull the pulling block 52 through the extension rope 6, thereby facilitating the disassembly of the signal transmission box 3.

[0034] In order to enhance the stability of the signal transmission box 3, a rubber pad 7 is fixed to the bottom of the signal transmission box 3. The rubber pad 7 is made of rubber material and its surface has a large friction coefficient. The bottom of the signal transmission box 3 cooperates with the upper surface of the support seat 2 and presses against the rubber pad 7, which increases the friction between the bottom of the signal transmission box 3 and the upper surface of the support seat 2, thereby enhancing the stability of the signal transmission box 3.

[0035] In order to enhance the stability of the support seat 2, an oblique support rod 8 is fixed to the side wall of the fixed plate 1, and the upper end of the oblique support rod 8 is fixed to the bottom of the support seat 2. The oblique support rod 8 supports and reinforces the bottom of the support seat 2, thereby enhancing the stability of the support seat 2.

[0036] The use principle of a fire protection system IoT signal transmission device in this embodiment is as follows:

[0037] The dovetail-shaped cross-section of the plug block 4 and the slot 21 prevents the plug block 4 from escaping from the slot 21 upwards, thereby improving the stability of the cooperation between the plug block 4 and the slot 21. The plug block 4 is inserted into the slot 21, and the pulling block 52 drives the limit rod 51 to maintain the plug-in state with the limit groove 41 under the elastic force of the tightening spring 53, so that the plug block 4 is limited in the slot 21, thereby fixing the plug block 4 and the signal transmission box 3 on the support seat 2. When the signal transmission box 3 needs to be disassembled, the staff only needs to pull the limit rod 51 downward by pulling the block 52, so that the limit rod 51 is separated from the limit groove 41 and enters the support seat 2, thereby removing the plug block 4 from the slot 21, eliminating the tedious operation of fixing with screws, and improving the efficiency of maintenance and repair of the signal transmission box 3.

[0038] 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.
