Description

Technical Field

[0001] This utility model belongs to the field of security system technology, and in particular relates to an early warning device for security. Background Technology

[0002] A security system is a system that uses security products and other related products to form an intrusion alarm system, video security monitoring system, access control system, explosion-proof security inspection system, etc.; or an electronic system or network that combines or integrates these systems as subsystems. In a security system, early warning devices are important early warning equipment that can play a role in security prevention.

[0003] A search revealed that publication number CN210515588U, filed on October 29, 2019, discloses an intelligent security early warning device, including a base plate and a gas alarm controller. A support plate is fixedly connected to the side wall of the base plate near the bottom. A groove adapted to the gas alarm controller is formed on the side wall of the base plate near the support plate. The bottom of the gas alarm controller abuts against the upper surface of the support plate, and the side of the gas alarm controller is engaged with the groove. A rotating plate is rotatably connected to the side of the support plate away from the base plate via a rotating shaft. The rotating plate and the gas alarm controller are fitted together, and the rotating plate and the support plate are connected by a positioning mechanism. The positioning mechanism includes a sliding cavity formed in the support plate, and a matching slider is slidably connected in the sliding cavity.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. Existing early warning devices for security use fix the gas alarm controller (i.e., the early warning box) with a positioning mechanism. This method cannot be adjusted according to the size of the early warning box, which limits its applicability.

[0006] 2. Existing early warning devices for security use complex positioning mechanisms, increasing manufacturing costs and hindering assembly and disassembly, thus affecting operational efficiency. Furthermore, the gas alarm controller (i.e., the early warning box) is mounted flush against the inside of the base plate, which impedes heat dissipation and reduces its effectiveness. Therefore, we provide an early warning device for security to address these issues. Utility Model Content

[0007] The purpose of this utility model is to provide an early warning device for security purposes. By setting an adjustment component, it can be adjusted according to the size of the early warning box, and has a wide range of applications. With the use of heat dissipation slots and installation components, it is easy for staff to quickly assemble and disassemble the early warning box. The structure is simple, the operation is labor-saving, and the work efficiency is improved. At the same time, the heat dissipation effect is effectively improved by the heat dissipation slots.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is an early warning device for security, including a first hollow plate and a second hollow plate disposed in front of it. The surface of the second hollow plate is provided with heat dissipation grooves, the rear end face of the second hollow plate is provided with adjustment components, and the four corners in front of the second hollow plate are provided with mounting components.

[0010] The adjustment assembly includes a knob located at the corner of the second hollow plate and a screw fixed at the center of one side wall of the knob, with a moving block spirally sleeved on the outer wall of the screw.

[0011] The mounting assembly includes a connecting seat located in front of the second hollow plate, and a rotating shaft rotatably mounted at the center of the front end face of the connecting seat, with a fixed cylinder fixed to the front end of the rotating shaft.

[0012] The present invention is further configured such that connecting plates are fixedly provided around the front end face of the first hollow plate, and the front end of the connecting plates is fixedly provided on the rear end face of the second hollow plate.

[0013] The present invention is further configured such that the corners of the surface of the first hollow panel are connected to the wall by bolts, and an early warning box is installed on the front of the second hollow panel.

[0014] The present invention is further configured such that the other end of the screw passes through the bearing on the first mounting base and the bearing on the second mounting base in sequence and is connected to the conical wheel, and the top of the first mounting base and the second mounting base are mounted on the rear end face of the second hollow plate.

[0015] The present invention is further configured such that a guide rod is fixed at the center of the front end face of the movable block, and the front end of the guide rod passes through the limiting hole in the second hollow plate and is connected to the connecting seat.

[0016] The present invention is further configured such that a limiting plate is slidably installed on the inner wall of the fixed cylinder, and a connecting rod is fixedly provided at the center of the front end face of the limiting plate.

[0017] The present invention is further configured such that the other end of the connecting rod passes through the through hole on the fixed cylinder and is connected to one end of the moving plate, and a spring is sleeved on the outer wall of the connecting rod.

[0018] The present invention is further configured such that the spring is located between the limiting plate and the inner wall of the fixed cylinder, and the other end of the rear end face of the moving plate is fixedly provided with an insert post.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, by setting an adjustment component, uses four sets of intermeshing conical wheels to drive four screws to rotate synchronously, causing four sets of moving blocks to expand outward or contract inward synchronously. This allows for corresponding adjustments based on the size of the warning box, significantly expanding its applicability. It solves the problem that existing security warning devices use a positioning mechanism to fix the gas alarm controller (i.e., the warning box), which cannot be adjusted according to the size of the warning box, thus limiting its applicability.

[0021] 2. This utility model, by setting up heat dissipation grooves and mounting components, utilizes a rotating shaft to achieve angle adjustment and uses the elastic force of a spring to drive the insertion post to quickly insert or remove from the mounting hole on the warning box, enabling workers to quickly assemble and disassemble the warning box. This structure is simple, easy to operate, and greatly improves work efficiency. At the same time, the design of the heat dissipation grooves effectively improves the heat dissipation effect of the warning box during operation, solving the problem that the positioning mechanism used in existing security warning devices is relatively cumbersome, increases manufacturing costs, and is inconvenient to assemble and disassemble, affecting work efficiency; in addition, the gas alarm controller (i.e., the warning box) is installed close to the inside of the base plate, which is not conducive to heat dissipation and affects the heat dissipation effect.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figures 1 to 4 This utility model is an early warning device for security purposes, including a first hollow plate 100 and a second hollow plate 103 disposed in front of it. An adjustment component 200 is disposed on the rear end face of the second hollow plate 103. The adjustment component 200 includes a knob 201 disposed at the corner of the second hollow plate 103 and a screw 201a fixed at the center of one side wall of the knob 201. A moving block 204 is spirally sleeved on the outer wall of the screw 201a.

[0033] Specifically, connecting plates 101 are fixed around the front end face of the first hollow plate 100, and the front end of the connecting plates 101 is fixed to the rear end face of the second hollow plate 103; the corners of the surface of the first hollow plate 100 are connected to the wall by bolts 102, and a warning box 104 is installed at the front of the second hollow plate 103; the other end of the screw 201a passes through the bearings on the first mounting base 202 and the second mounting base 203 in sequence and is connected to the conical wheel 206; the tops of the first mounting base 202 and the second mounting base 203 are installed on the rear end face of the second hollow plate 103; a guide rod 205 is fixed at the center of the front end face of the moving block 204, and the front end of the guide rod 205 passes through the limiting hole on the second hollow plate 103 and is connected to the connecting seat 301.

[0034] Furthermore, the first hollow plate 100 and the second hollow plate 103 adopt a hollow structure, which helps to reduce costs and improve heat dissipation performance. The moving block 204 is slidably installed on the rear end face of the second hollow plate 103, playing a role in assisting movement and guidance. The warning box 104 is existing technology, so it will not be described in detail here. The knob 201, screw 201a, moving block 204, and conical wheel 206 are all provided in four sets. Among them, the external threads on the outer walls of the two diagonally opposite screws 201a are arranged in opposite directions. Therefore, when the two diagonally opposite screws 201a rotate, they will drive the diagonally opposite moving block 204 to move in opposite directions.

[0035] The operation process of this embodiment is as follows: When the staff needs to install the warning box 104, the warning box 104 is first placed on the surface of the second hollow plate 103. Then, one of the knobs 201 is rotated. The knob 201 is forced to rotate the corresponding screw 201a, and the rotation of the screw 201a will drive the corresponding conical wheel 206 to rotate. There are four sets of knobs 201, screws 201a, conical wheels 206 and moving blocks 204. The outer walls of the four sets of conical wheels 206 are meshed. Therefore, when a certain screw 201a rotates, the four sets of conical wheels 206 are driven by the rotation of the screws 201a. Under its action, it will drive the other three sets of screws 201a to rotate. The two sets of screws 201a set diagonally opposite each other have opposite external threads on their outer walls. The screws 201a are screwed into the threaded holes on the moving blocks 204. Therefore, when the four sets of screws 201a rotate, the diagonally opposite screws 201a will drive the diagonally opposite moving blocks 204 to move in opposite directions. This allows the four sets of moving blocks 204 to expand outward or contract inward synchronously. It can be adjusted according to the size of the warning box 104 and has a wide range of applications.

[0036] Example 2

[0037] Please see Figure 4 and Figure 5 Based on Embodiment 1, the difference from the first embodiment is that a heat dissipation groove 103a and a mounting assembly 300 are provided. The mounting assembly 300 includes a connecting seat 301 disposed in front of the second hollow plate 103, and a rotating shaft 301a rotatably mounted at the center of the front end face of the connecting seat 301. A fixing cylinder 302 is fixedly provided at the front end of the rotating shaft 301a. This solves the problem that the existing positioning mechanism used in security early warning devices has a relatively cumbersome structure, increases manufacturing costs, and is inconvenient to disassemble and assemble, thus affecting work efficiency. In addition, the gas alarm controller (i.e., the early warning box) is attached to the inside of the substrate, which is not conducive to heat dissipation and affects the heat dissipation effect.

[0038] Specifically, a limiting plate 303 is slidably installed on the inner wall of the fixed cylinder 302, and a connecting rod 304 is fixedly provided at the center of the front end face of the limiting plate 303; the other end of the connecting rod 304 passes through the through hole on the fixed cylinder 302 and is connected to one end of the moving plate 305; a spring 304a is sleeved on the outer wall of the connecting rod 304; the spring 304a is located between the limiting plate 303 and the inner wall of the fixed cylinder 302, and an insert post 305a is fixedly provided at the other end of the rear end face of the moving plate 305.

[0039] Furthermore, the angles of the fixed cylinder 302 and the movable plate 305 can be adjusted using the rotating shaft 301a to achieve the purpose of adjusting the position of the insert 305a. The connecting rod 304 connects the movable plate 305 and the limiting plate 303, playing a role in connecting and transmitting power. Under the action of the spring 304a, the movable plate 305 can be moved.

[0040] The operation process of this embodiment is as follows: After adjusting the positions of the four sets of moving blocks 204, the moving plate 305 is pulled outward first. The moving plate 305 moves outward under the force. The inner wall of the moving plate 305 is connected to the limiting plate 303 through the connecting rod 304. Therefore, the outward movement of the moving plate 305 will drive the limiting plate 303 to move under the action of the connecting rod 304, and squeeze the spring 304a. At this time, the moving plate 305 and the insert 305a will be pulled out a certain distance. Then the fixed cylinder 302 applies force to make it rotate around the shaft 3 01a is a circular rotation, rotating the insertion post 305a to the outside of the mounting hole on the warning box 104, and then stopping the force applied to the moving plate 305. At this time, under the elastic action of the spring 304a, the moving plate 305 is bounced back, and the insertion post 305a is inserted into the corresponding mounting hole on the warning box 104, which plays a limiting role, making it easy for staff to quickly disassemble and assemble the warning box 104, saving time and effort, with high work efficiency and simple structure. In addition, when the warning box 104 is in use, the heat dissipation groove 103a can be used to improve the heat dissipation effect.
