Description

Technical Field

[0001] The utility model is applicable to the technical field of security monitoring, and particularly relates to a security monitoring device for a weak current project which is convenient to install. Background Technique

[0002] At present, for a weak current project, this kind of project mainly provides electrical energy for people and converts electrical energy into other forms of energy, such as the electricity consumption of household appliances such as air conditioners and refrigerators, and the lighting electricity of electric lights. In order to improve the control and protection of the weak current control cabinet, corresponding monitoring facilities are often set in the centralized placement room of the weak current control cabinet for security monitoring.

[0003] However, the security monitoring mechanisms currently in use are often composed of a monitoring camera and a signal transmission line. The monitoring camera is often set on the top of the ceiling for monitoring in a large range from the top. In this process, the monitoring camera is often integrally formed with a corresponding installation base, and the installation base and the monitoring camera can be assembled by the structural action of expansion bolts. In this process, the monitoring camera cannot be directly disassembled and separated from the installation base. As a result, once the monitoring camera is damaged, maintenance personnel need to re-dismantle the installation base to repair the camera and then reinstall it, which makes the overall operation process too cumbersome and affects the normal use of the monitoring camera. Therefore, we propose a security monitoring device for a weak current project which is convenient to install. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a security monitoring device for a weak current project which is convenient to install, and can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A security monitoring device for a weak current project which is convenient to install, including a fixed base, an expansion bolt is inserted through the side of the fixed base in an activity manner, a bearing base is detachably installed on the top of the fixed base, and a monitoring camera is fixedly installed on the top surface of the bearing base;

[0007] A limiting mechanism is arranged inside the fixed base, fixing mechanisms are fixedly installed on the surfaces of the four corners at the bottom of the bearing base, and the fixing mechanisms are inserted into the inside of the fixed base in an activity manner. Guide grooves are opened at both ends of one side of the fixed base close to the hand-pulling plate, and a movable rod is inserted through and slidably inserted into the inside of the guide groove.

[0008] By adopting the above technical solution, under the structural action of the limiting mechanism and the fixing mechanism, the carrying base and the monitoring camera can be conveniently and quickly installed and used with the fixed base, which is convenient for the maintenance of the monitoring camera and the use of security monitoring.

[0009] As an alternative solution of the technical solution of the present application, the limiting mechanism includes a limiting block and a return spring. On both sides of the inner part of the fixed base, activity grooves are horizontally opened. In each activity groove, a pressing plate is slidably installed. On both sides of each pressing plate, transmission plates are fixedly installed. Between the sides of the two groups of transmission plates, they are fixedly connected to the outside of the limiting block. In the middle of the side of each pressing plate away from the limiting block, an activity rod is horizontally fixedly installed. On the outer surface of each activity rod, a return spring is movably sleeved, and the return spring is movably arranged inside the activity groove.

[0010] By adopting the above technical solution, under the mutual transmission structural action of the return spring and the limiting block, the limiting block can cause a reaction force on the pushing block so that the pushing block will not be removed from the inside of the fixed base arbitrarily, thereby realizing the rapid installation of the monitoring camera and the fixed base, which is convenient for the maintenance of the monitoring camera and the use of security monitoring.

[0011] As an alternative solution of the technical solution of the present application, on the surface of the side of each activity rod away from the pressing plate, an activity plate is fixedly installed, and the outside of the activity plate is movably attached to the outside of the fixed base. Between the outside of the two groups of activity plates, a hand-pulling plate is fixedly installed, and the hand-pulling plate is movably arranged outside the fixed base.

[0012] By adopting the above technical solution, under the structural action of the hand-pulling plate, it is further convenient for the operator to disassemble and separate the monitoring camera and the fixed base.

[0013] As an alternative solution of the technical solution of the present application, the fixing mechanism includes a pushing block. Vertically fixed installation rods are installed on the surfaces of the four corners of the bottom of the carrying base, and the bottom of the connecting rod and the top surface of the pushing block are fixedly connected. The pushing block is slidably inserted between the outside of the transmission plates.

[0014] By adopting the above technical solution, through the structural action of the connecting rod, the pushing block and the carrying base are driven and connected, so as to ensure that under the reaction force and limiting action of the limiting block on the pushing block, the carrying base and the monitoring camera will not fall off arbitrarily and affect the subsequent normal use.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] 1. A security monitoring device for weak current engineering that is easy to install in the technical solution of the present application. By arranging an extrusion plate inside the fixed base, and arranging a transmission plate on the side of the extrusion plate, a limiting block that can move horizontally inside the fixed base is provided. Combined with a push block in the shape of a right-angled triangle that is adapted to the limiting block arranged at the bottom of the bearing base, when it is necessary to assemble and install the bearing base, the monitoring camera and the fixed base, only by continuously pushing the bearing base, the push block can be driven to synchronously insert into the movable groove. After the inclined surface of the push block presses against the inclined surface of the limiting block, the extrusion plate and the movable rod are driven to move rightward synchronously. Until the inclined surface of the push block disengages from the inclined surface of the limiting block, under the reverse pushing action of the return spring, the extrusion plate and the push block can be synchronously restored and moved leftward. After the right-angled side of the bottom surface of the limiting block fits with the right-angled side of the top surface of the push block, the limiting block can press against the push block so that the push block will not be arbitrarily removed from the fixed base, thereby realizing the rapid installation of the monitoring camera and the fixed base, facilitating the maintenance of the monitoring camera and the use of security monitoring.

[0017] 2. A security monitoring device for weak current engineering that is easy to install in the technical solution of the present application. By arranging a hand-pulling plate between two groups of movable plates on the side of the fixed base, when disassembling and separating the bearing base and the monitoring camera, the maintenance personnel only need to pull the hand-pulling plate outward, and then the movable rods and the limiting blocks located on both sides inside the fixed base can be driven to move synchronously. Furthermore, the limiting block can be moved away from the top surface of the push block below it, so that the push block loses the anti-moving and limiting effect of the limiting block on it, thereby facilitating the maintenance personnel to disassemble and separate the bearing base and the monitoring camera, and further improving the maintenance efficiency of the maintenance personnel for the monitoring camera.

Detailed implementation mode

[0022] As Figures 1-3 shown, the utility model provides a technical solution: a weak current engineering security monitoring device convenient for installation. An expansion bolt 11 is inserted through the side of a fixed base 1 in an activity manner. A bearing base 12 is detachably installed on the top of the fixed base 1. A monitoring camera 13 is fixedly installed on the top surface of the bearing base 12. A corresponding data connection line is arranged on the side of the monitoring camera 13 to facilitate the transmission of the image signal monitored by it for subsequent viewing and use.

[0023] In this technical solution (as shown by Figure 1 , Figure 2 and Figure 3 ), a limiting mechanism is arranged inside the fixed base 1. The limiting mechanism includes a limiting block 23 and a return spring 26. Activity grooves 2 are horizontally opened on both sides inside the fixed base 1. An extrusion plate 21 is slidably installed in each activity groove 2. Transmission plates 22 are fixedly installed on both side surfaces of each extrusion plate 21. The outer sides between the two groups of transmission plates 22 are fixedly connected to the outer side of the limiting block 23. An activity rod 27 is horizontally fixedly installed at the middle end of one side of each extrusion plate 21 away from the limiting block 23. A return spring 26 is movably sleeved on the outer surface of each activity rod 27, and the return spring 26 is movably arranged inside the activity groove 2.

[0024] In this technical solution (as shown by Figure 1 , Figure 2 and Figure 3 ), fixing mechanisms are fixedly installed on the surfaces of the four corners at the bottom of the bearing base 12, and the fixing mechanisms are inserted into the inside of the fixed base 1 in an activity manner. The fixing mechanism includes a pushing block 25. Connecting rods 24 are vertically fixedly installed on the surfaces of the four corners at the bottom of the bearing base 12, and the bottom of the connecting rod 24 and the top surface of the pushing block 25 are fixedly connected. The pushing block 25 is slidably inserted between the outer sides of the transmission plates 22.

[0025] In this technical solution (as shown by Figure 1 , Figure 2 and Figure 3 ), an activity plate 28 is fixedly installed on the surface of one side of each activity rod 27 away from the extrusion plate 21, and the outer side of the activity plate 28 is movably attached to the outer side of the fixed base 1. A pulling plate 3 is fixedly installed between the outer sides of the two groups of activity plates 28, and the pulling plate 3 is movably arranged on the outer side of the fixed base 1.

[0026] In some technical solutions (as shown by Figure 1 , Figure 2 and Figure 3 ), guiding grooves 4 are opened at both ends of one side of the fixed base 1 close to the pulling plate 3, and the activity rod 27 is inserted through and slidably inserted into the inside of the guiding groove 4.

[0027] During operation, after placing the bearing base 12 and the monitoring camera 13 to be installed and used on the surface of the fixed base 1, align the pushing block 25 provided on the side of the bearing base 12 with the insertion slot opened at the top of the fixed base 1 and insert it into the movable slot 2. After the inclined surface of the pushing block 25 is fitted with the inclined surface of the limiting block 23, continuously press the bearing base 12. When the pushing block 25 moves vertically, it presses against the limiting block 23, causing it to drive the transmission plate 22 and the extrusion plate 21 to move horizontally to the right synchronously under the transmission action of the transmission plate 22. After the return spring 26 is compressed and deformed, until the inclined surfaces of the pushing block 25 and the limiting block 23 are separated, the pushing force of the pushing block 25 on the limiting block 23 is lost. Under the reverse pushing action of the return spring 26, the limiting block 23 can move to the left synchronously to restore its position. Then, the limiting block 23 is located on the top surface of the pushing block 25, that is, the right-angled side of the bottom surface of the limiting block 23 is in contact with the right-angled side of the top surface of the pushing block 25 to perform anti-movement limiting treatment. Thus, the bearing base 12 and the monitoring camera 13 can be set on the surface of the fixed base 1. Then, the bottom surface of the fixed base 1 is attached to the surface of the ceiling to be installed, so that the monitoring camera 13 is below the ceiling to perform security monitoring on its lower side. When it is necessary to disassemble and repair the monitoring camera 13, pull the hand-pulling plate 3 to the right. Then, under the transmission action of the movable rod 27 and the transmission plate 22, the limiting block 23 can be driven to move to the right synchronously inside the movable slot 2. After the limiting block 23 is separated from the top surface of the pushing block 25, the anti-movement limiting force of the limiting block 23 on the pushing block 25 is lost, and the bearing base 12 and the fixed base 1 are separated, which is convenient for disassembling the monitoring camera 13 to facilitate subsequent repair treatment.
