Description

Technical Field

[0001] This utility model belongs to the field of security terminal technology, specifically a security terminal fixing device. Background Technology

[0002] With the rapid development of smart cities, smart parks, smart transportation and other fields, security systems have been upgraded from the traditional "passive defense" to "active early warning and intelligent linkage". As the "nerve node" of the system, the security terminal box undertakes core functions such as power supply, signal transmission and equipment control. The reliability of its installation and fixation directly determines the stable operation of the security system.

[0003] Meanwhile, a smart city security terminal fixing device with application number CN202021832612.4 includes a mounting block embedded in a wall and a mounting plate outside the wall. The mounting blocks are symmetrically arranged at the upper and lower ends of the wall, with the right side of the mounting block embedded in the wall in an L-shape and the left side extending outward in a T-shape. The upper and lower ends of the right side of the mounting plate are provided with T-shaped grooves, and the left side of the mounting block is inserted into the T-shaped grooves and fixed to the mounting plate. A fixing plate is provided on the left side of the mounting plate, and a slot is provided on the fixing plate. The lower end of an inner insert plate is inserted into the slot, and the upper end of the inner insert plate is connected to the outer insert plate through a connecting plate. The outer insert plate is located on the left side outside the fixing plate, and the center of the outer insert plate is... The mounting plate is provided with a fixing recess and a mounting hole in the center. The second fixing screw is fixed to the mounting plate through the recess and the mounting hole. The top plate is symmetrically provided at the upper and lower ends of the left side of the outer insert plate, and the top plates are connected to each other through the front and rear side plates. The right side of the side plate is fixed to the outer insert plate. The lower end of the upper top plate is connected to the extrusion plate through multiple first elastic elements. The front and rear sides of the extrusion plate are connected to the side plates through a sliding mechanism. The sliding mechanism includes a sliding groove provided on the inner side of the side plate and a slider provided at the front and rear ends of the extrusion plate. The slider is inserted into the sliding groove and slidably connected to the sliding groove. A spring buckle is provided at the lower right end of the extrusion plate. A bottom plate is provided above the lower top plate.

[0004] However, the following problems were found in the implementation of the relevant technology: It lacks a reference positioning structure. During installation, it relies solely on manual visual observation or simple level calibration. It is easy for the cabinet to shift due to hand tremors or uneven wall surfaces. In addition, in order to deal with outdoor dust and insect intrusion, most terminal boxes are equipped with dust filters, but no independent filter replacement channel is designed. During maintenance, the power supply of the terminal box must be disconnected (to avoid electric shock), the cabinet door screws must be unscrewed, and the cabinet must be opened before the filter can be taken out for replacement, resulting in a long replacement time.

[0005] Therefore, we propose a security terminal fixing device. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a security terminal fixing device, which has the advantages of allowing the bracket to be installed first, and then the housing to be installed by positioning and sliding in, thereby improving the alignment accuracy. At the same time, the filter can be replaced without disassembling the housing, thus improving convenience.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a security terminal fixing device, including a wall, an installation bracket fixedly connected to the outer surface of the wall, a base plate fixedly connected to the bottom of the installation bracket, a positioning groove provided on the base plate, a terminal box body installed on the installation bracket, a positioning block fixedly connected to the lower surface of the terminal box body, a slot provided on the terminal box body, a filter plate detachably connected to the slot, an insertion block fixedly connected to the lower surface of the top plate of the filter plate, a locking hole provided on the insertion block, an insertion hole provided on the terminal box body, an installation plate fixedly connected to the inner surface of the insertion hole, a spring fixedly connected to the outer surface of the installation plate, and a locking block fixedly connected to the other end of the spring.

[0008] Preferably, the positioning block is slidably connected to the positioning groove, and the positioning block and the positioning groove are provided with a second threaded hole.

[0014] Preferably, the top plate of the filter plate is provided with a sealing layer, and a handle is fixedly connected to the upper surface of the filter plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the cooperation of the mounting bracket, base plate, positioning groove, terminal box body and positioning block, allows the bracket to be installed first, and then the box body to be installed by positioning and sliding in. This improves the accuracy of alignment, reduces the need for secondary drilling and correction, shortens the installation time, reduces repetitive work, and allows operators to complete the sliding and locking on a stable structure, reducing the risk of falling due to suspension and shaking.

[0016] 2. This utility model, through the cooperation of slots, filter plates, inserts, locking holes, mounting plates, springs, and locking blocks, allows filter replacement without disassembling the box, significantly shortening on-site maintenance time, reducing system downtime, simplifying operation steps, and reducing the risk of accidental contact, electric shock, or falling due to opening the box and exposing internal components. It also reduces the wear and aging of internal instruments by not frequently opening the box, maintaining dustproof and waterproof performance, reducing the need for professional tools and training, and allowing on-site personnel to complete filter replacement, thus reducing labor costs.
