Description

Technical Field

[0001] This application relates to the field of security gates, and more specifically, to a movable security gate. Background Technology

[0002] Security gates are devices that use the principle of electromagnetic induction to detect metal objects carried by people. They emit alternating electromagnetic fields, and when a metal object causes an eddy current effect that changes the magnetic field distribution, an alarm is triggered. They can detect metal objects as small as paperclips and are mainly used for security checks in public places such as airports, train stations, and large events, as well as for corporate theft prevention and industrial metal control.

[0003] Most existing security gates are fixed installations, or although they are equipped with rollers at the bottom, they lack an effective stable support mechanism. After being moved to the designated position, they are only fixed by the simple locking device on the rollers, which has poor stability. They are prone to displacement when people pass through or when they are hit by external forces, affecting the detection accuracy and even posing a risk of tipping over. Therefore, we have proposed a movable security gate. Summary of the Invention

[0004] To overcome the above shortcomings, this application provides a movable security gate, which aims to improve the problem of low stability of existing security gates.

[0005] This application provides a movable security gate, including a security gate body. Two support plates are installed at the bottom of the security gate body. Lifting components are installed on both support plates. Roller sets are installed at the bottom of both lifting components. Support frames are installed at the bottom of both support plates. The two roller sets are located in the two support frames respectively. Retractable counterweight components are installed on the side walls of both support frames.

[0006] In one specific implementation, the lifting assembly includes a threaded rod that is threaded through the support plate, a lifting plate that is rotatably connected to the bottom of the threaded rod, the lifting plate that is slidably disposed within the support frame, and a roller assembly that is installed at the bottom of the lifting plate.

[0007] In one specific implementation, a positioning plate is fixedly installed on the top of the support plate, the threaded rod rotates through the positioning plate, and a positioning block is fixedly sleeved on it, with the positioning block in contact with the positioning plate.

[0008] In one specific implementation, the support plate and the security gate body are equipped with the same protective cover, the protective cover is placed on the threaded rod, and the gate body is installed on the protective cover.

[0009] In one specific implementation, the roller assembly includes directional wheels and omnidirectional wheels, both of which are mounted on the bottom of the lifting plate.

[0010] In one specific implementation, the counterweight assembly includes a plurality of cylinders, all of which are mounted on the support frame. The output shafts of the plurality of cylinders slide through one end sidewall of the support frame, and the output shafts of the plurality of cylinders are connected to the same counterweight.

[0011] In one specific implementation, the counterweight includes a connecting seat, on one side wall of the connecting seat are fixedly installed a plurality of telescopic rods, one end of the plurality of telescopic rods is fixedly connected to the same first counterweight block, and a plurality of second counterweight blocks are slidably sleeved on the plurality of telescopic rods.

[0012] In one specific implementation, a fixing rod is installed on the side wall of the support plate, and an L-shaped plate is slidably sleeved on the fixing rod, the L-shaped plate being hooked onto one end side wall of the first counterweight.

[0013] The beneficial effects of this application are as follows: By installing two support blocks at the bottom of the security gate body, and installing lifting components on the two support blocks, and installing roller sets at the bottom of the lifting components, and simultaneously installing support frames at the bottom of both support plates, the roller sets can be stored in the support frames through the lifting components, so that the support frames are placed on the ground and support the security gate body. In addition, several cylinders are installed on the support frames, and the output shafts of the several cylinders are connected to the same counterweight. The counterweight is placed on the ground, and the cylinders can adjust the position of the counterweight on the ground to increase the overall counterweight and floor space, thereby improving the stability of the security gate body.

Detailed Implementation

[0017] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0018] Please see Figure 1-5 This application provides a movable security gate, including a gate body 10. Two support plates 20 are mounted on the bottom of the gate body 10, and each support plate 20 is equipped with a lifting assembly 30. Each lifting assembly 30 has a roller assembly 40 mounted on its bottom. Specifically, the roller assembly 40 is placed on the ground to facilitate moving the gate body 10. Each support plate 20 has a support frame 50 mounted on its bottom. When the gate body 10 is pushed to the desired position, the lifting assembly 30 drives the roller assembly 40 to move, thus... The roller assembly 40 is housed within the support frame 50. The two roller assemblies 40 are located within the two support frames 50 respectively. The roller assembly 40 is housed within the support frame 50 and supports the security gate body 10 through the two support frames 50. A retractable counterweight assembly 60 is installed on the side wall of each of the two support frames 50. The bottom of the counterweight assembly 60 is flush with the bottom of the support frame 50. Thus, when the support frame 50 is placed on the ground, the counterweight assembly 60 is placed on the ground, thereby improving the stability of the security gate body 10.

[0019] See Figure 4 and 5 The lifting assembly 30 includes a threaded rod 310, which is threaded through the support plate 20. Specifically, the support plate 20 has a threaded hole, and the threaded rod 310 is adapted to the threaded hole. The bottom of the threaded rod 310 is rotatably connected to a lifting plate 320. Rotating the threaded rod 310 causes the lifting plate 320 to rise and fall. The lifting plate 320 is slidably disposed within the support frame 50. A roller assembly 40 is installed at the bottom of the lifting plate 320, and the lifting plate 320 causes the roller assembly 40 to rise and fall.

[0020] See Figure 5 A positioning plate 210 is fixedly installed on the top of the support plate 20. Specifically, the positioning plate 210 is U-shaped. The threaded rod 310 rotates through the positioning plate 210. When set, the cylindrical part of the threaded rod 310 rotates through the positioning plate 210. A positioning block 330 is fixedly sleeved on the threaded rod 310. The positioning block 330 is in contact with the positioning plate 210. By installing the positioning block 330 on the threaded rod 310, the downward height of the threaded rod 310 can be fixed so that the two roller groups 40 on both sides descend to the same height. The positioning block 330 is then lowered onto the positioning plate 210.

[0021] See Figure 1 and 2 The same protective cover 70 is installed on the support plate 20 and the security gate body 10. The protective cover 70 covers the threaded rod 310, and the door body 710 is installed on the protective cover 70. The specific installation structure of the door body 710 is the existing technology. The threaded rod 310 can be used by opening the door body 710. Furthermore, the roller assembly 40 includes a directional wheel 410 and a universal wheel 420. The directional wheel 410 and the universal wheel 420 are both installed at the bottom of the lifting plate 320. The directional wheel 410 and the universal wheel 420 are respectively installed on both sides of the bottom of the lifting plate 320.

[0022] See Figure 3 and 4 The counterweight assembly 60 includes several cylinders 610. Specifically, the several cylinders 610 move synchronously and are all mounted on the support frame 50. The output shafts of the several cylinders 610 slide through one side wall of the support frame 50. The output shafts of the several cylinders 610 are connected to the same counterweight 620. The several cylinders 610 drive the counterweight 620 to move, so that the counterweight 620 slides on the ground to adjust the footprint of the security gate body 10. This allows for adjustment of the footprint according to actual conditions, thereby improving the overall stability of the security gate body 10.

[0023] See Figure 4The counterweight 620 includes a connecting seat 6210. Several telescopic rods 6220 are fixedly installed on one side wall of the connecting seat 6210. One end of each telescopic rod 6220 is fixedly connected to the same first counterweight block 6230. Several second counterweight blocks 6240 are slidably sleeved on the telescopic rods 6220. Specifically, the second counterweight blocks 6240 have through holes adapted to the telescopic rods 6220. By setting the telescopic rods 6220, the floor space can be further adjusted. Furthermore, a fixing rod 220 is installed on the side wall of the support plate 20. An L-shaped plate 230 is slidably sleeved on the fixing rod 220. The L-shaped plate 230 hooks onto one side wall of the first counterweight block 6230. When the counterweight 620 is in the retracted state, it is hooked onto one side of the first counterweight block 6230 by the L-shaped plate 230 to achieve the purpose of limiting the position of the counterweight 620.

[0024] When using this movable security gate: rotating the threaded rod 310 causes the lifting plate 320 to move downwards, simultaneously causing the positioning block 330 to move downwards. This causes the lifting plate 320 to move the roller assembly 40 downwards, supporting the security gate body 10. The positioning block 330 then moves onto the positioning plate 210, allowing the roller assemblies 40 on both sides to support the security gate body 10. Afterwards, the security gate body 10 can be pushed to the desired position and stopped. Rotating the threaded rod 310 causes the roller assembly 40 to retract into the support frame 50. With the support frames 50 on both sides supporting the security gate body 10, the cylinder 610 can be activated to move the counterweight 620, thereby improving the overall stability of the security gate body 10.

[0025] It should be noted that the specific model and specifications of the security gate body 10 and cylinder 610 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0026] The power supply and operating principle of the security gate body 10 and cylinder 610 are clear to those skilled in the art and will not be described in detail here.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
