Description

Technical Field

[0001] This utility model relates to the field of bracket technology, specifically an adjustable bracket for an infrared beam-emitting device. Background Technology

[0002] Infrared beam detectors typically consist of an infrared transmitter and an infrared receiver. The transmitter emits a beam of infrared light, which the receiver receives. When an object blocks the beam, the receiver cannot detect the signal, thus triggering an alarm. Infrared beam alarms are widely used in airports for security. In airports, infrared beam intrusion alarm systems can be integrated with video surveillance to effectively enhance anti-tailgating, anti-missed detection, and anti-intrusion capabilities.

[0003] When installing infrared beam detectors inside airports, the existing trusses within the airport are often used as the installation base, such as... Figure 1 As shown, in some installation locations, the axis of the gantry is not horizontal. If an infrared beam detector is installed in these locations, it will be difficult to align the infrared transmitter and receiver after installation, making the installation difficult. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adjustable bracket for an infrared beam-and-beam device, which can better align the infrared transmitter and the infrared receiver.

A connecting post is provided on the mounting plate, and first connecting plates are vertically arranged on both sides of the connecting post. An arc plate is provided above each first connecting plate, and a second connecting plate is vertically arranged above each arc plate. The second connecting plate is provided with a first connecting hole. A first screw passes through two first connecting holes in sequence and is connected to a first nut. A second connecting hole is provided on the connecting post, and the axis of the second connecting hole is perpendicular to the axis of the connecting post. An elongated hole is provided on the first connecting plate to cooperate with the second connecting hole. The extension direction of the elongated hole is the same as the extension direction of the first connecting plate. A second screw passes through the second connecting hole and the elongated hole and is connected to a second nut.

[0006] Furthermore, a third connecting hole is provided on the top of the first connecting plate, and the third screw passes through two third connecting holes in sequence and is connected to the third nut.

[0007] Furthermore, the inner surface of the arc plate is provided with an anti-slip structure.

[0008] Furthermore, the anti-slip structure is a rubber strip, and the surface of the rubber strip has interlaced raised stripes or dot matrix pits.

[0009] Furthermore, both the ends of the first screw and the second screw are fitted with elastic damping sleeves.

[0010] Furthermore, a positioning plate is provided at the bottom of the mounting plate, and a level bubble is provided on the positioning plate.

[0011] The beneficial effects of this utility model are: an installation space is formed between the two arc plates for connection with the frame; the relative position of the connecting column and the first connecting plate can be adjusted through the elongated hole, and the installation height of the mounting plate can be adjusted; at the same time, the connecting column can also rotate around the second screw, and when it rotates to the appropriate position, it is locked by the second nut, which can better ensure that the infrared transmitter and the infrared receiver are aligned after installation.

Detailed Implementation

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] like Figures 2-4As shown, this utility model discloses an adjustable bracket for an infrared beam-emitting device, comprising a mounting plate 1, on which a plurality of mounting holes 2 are evenly distributed, a connecting post 3 is provided on the mounting plate 1, and first connecting plates 4 are vertically arranged on both sides of the connecting post 3. An arc plate 5 is provided above each first connecting plate 4, and a second connecting plate 6 is vertically arranged above each arc plate 5. The second connecting plate 6 is provided with a first connecting hole, and a first screw 7 passes through two first connecting holes in sequence and is connected to a first nut 8. The connecting post 3 is provided with a second connecting hole, the axis of which is perpendicular to the axis of the connecting post 3. The first connecting plate 4 is provided with an elongated hole 9 that cooperates with the second connecting hole, the extension direction of the elongated hole 9 being the same as the extension direction of the first connecting plate 4. The second screw 9 passes through the second connecting hole and the elongated hole 9 and is connected to a second nut 11.

[0019] The mounting plate 1 is a rectangular metal plate with multiple mounting holes 2 evenly distributed on its surface for connecting an infrared transmitter or receiver to the mounting plate 1 via bolts. The connecting column 3 is a rectangular metal rod with a flattened end that connects to the mounting plate 1, allowing the mounting plate 1 and the connecting column 3 to be connected by welding. The first connecting plate 4 is a long strip of metal plate with an arc plate 5 connected to its upper end. The arc plate 5 is an arc-shaped metal sheet with a central arc angle of 120°-150°. A second connecting plate 6 is vertically welded above the arc plate 5. The second connecting plate 6 has a first connecting hole. A first screw 7 passes through the first connecting holes of the two second connecting plates 6 and is locked by a first nut 8, thus forming an adjustable clamping space. During use, the frame is clamped between the two arc plates 5. By adjusting the position of the second screw 9 in the elongated hole 9, the relative height between the connecting post 3 and the first connecting plate 4 can be adjusted, thereby adjusting the overall installation height of the mounting plate 1. At the same time, the connecting post 3 can also rotate around the second screw 9. When it rotates to a suitable position, it is locked by the second nut 11, which can adjust the installation angle of the mounting plate 1.

[0020] To accommodate trusses of different sizes, the top of the first connecting plate 4 is further provided with a third connecting hole. The third screw 11 passes through two third connecting holes in sequence and is connected to the third nut 13. By loosening the third nut 13, the distance between the two arc plates 5 can be adjusted to accommodate trusses of different diameters; after tightening, the truss can be securely clamped.

[0021] To improve stability after connection with the truss, the inner surface of the arc plate 5 is further provided with an anti-slip structure 14. The anti-slip structure 14 can be a rubber strip, which can be connected to the inner surface of the arc plate 5 by adhesive bonding. Preferably, the anti-slip structure 14 is a rubber strip with alternating raised stripes or dot matrix pits on its surface.

[0022] To prevent the first nut 8 from slipping off the first screw 7, and to prevent the second nut 11 from slipping off the second screw 9, the ends of both the first screw 7 and the second screw 9 are fitted with elastic damping sleeves 15.

[0023] Furthermore, a positioning plate 16 is provided at the bottom of the mounting plate 1, and a spirit level 17 is provided on the positioning plate 16. The positioning plate 16 is welded to the bottom of the mounting plate 1. The positioning plate 16 is an L-shaped metal plate, and a spirit level 17 is embedded in its horizontal section. During installation, the levelness of the mounting plate 1 can be quickly adjusted by observing the position of the bubble in the spirit level 17, ensuring the alignment accuracy between the infrared transmitter and the receiver.

[0024] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
