Description

Technical Field

[0001] This utility model relates to the field of safety engineering technology, specifically a safety engineering publicity bracket. Background Technology

[0002] The purpose of safety engineering publicity is to prevent and mitigate the losses to people and property caused by accidents, disasters and criminal activities. The main method is to publicize technical content such as risk assessment, safety planning, safety management and emergency response, so as to improve individuals, organizations and society's timely understanding of the causes of various safety threats, and thus make self-awareness and preventive measures.

[0003] However, the existing promotional devices used in supporting safety engineering publicity activities are mostly large display board structures. Although they provide a large display area, their large footprint and inconvenience in moving them limit their scope of use and make them unsuitable for use in actual construction site environments. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a safety engineering publicity bracket, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a safety engineering publicity bracket, including a base, and two support frames are provided on both sides of the top of the base. The two support frames can be staggered and fitted on the top surface of the base. The front and rear ends of the two support frames are fixed to the top of the base by a bearing seat through a pin. The publicity board is movably installed on the surface of the two support frames.

[0006] The base has two transmission gears, two opposing straight tooth plates, and a double cam transmission assembly in its middle. The two opposing straight tooth plates are slidably mounted on both sides of the top of the base and can be pushed and driven by the double cam transmission assembly. Limiting springs are installed on one end surface of each of the two straight tooth plates, and one end of the limiting spring is fixedly connected to a limiting seat installed on the top of the base. The middle parts of the two transmission gears are respectively fitted into the bottom of the two support frames and respectively mesh with the other end of the two straight tooth plates.

[0007] The two straight toothed plates are designed with a semi-circular structure at one end to facilitate subsequent pressure application, and both straight toothed plates have a slide rail installed on the top of the base that is engaged with the inner bottom side of the plate.

[0008] The preferred embodiment of the dual cam transmission assembly includes an adjusting shaft. One end of the adjusting shaft is mounted in the top structure of the base via a bearing. A dual cam plate, capable of pressing and driving the other ends of two straight gear plates respectively, is installed in the middle of the adjusting shaft. A threaded hole is provided on the top of the base. An arc-shaped clearance groove is provided inside the dual cam plate to align with the threaded hole. The dual cam plate and the base can be limited and installed by means of screws passing through the arc-shaped clearance groove and being threaded to the threaded hole. In addition to pressing and driving the two straight gear plates synchronously, the dual cam transmission assembly can also lock itself to the base to ensure the stability of the two straight gear plates and the two transmission gears after adjustment.

[0009] Preferably, the top of the adjusting shaft is equipped with a limiting frame plate and a torsion plate. The two sides of the bottom of the limiting frame plate can be respectively connected to the top of one end of two straight toothed plates. The number of torsion plates is not less than two and they are evenly distributed along the circumference of the adjusting shaft, thereby facilitating the application of force to the adjusting shaft.

[0010] In particular, the advertising board has composite clearance grooves in both the front and rear ends, and the support frame has limit rods installed on the surfaces of both the front and rear ends. During the installation of the advertising board on the surface of the support frame, the composite grooves first fit with the limit rods to make clearance and then fit with the sliding limit rods to make clearance.

[0011] The composite groove is composed of a strip groove and a circular hole groove that communicates with its own space. The limiting rod is a T-shaped structure, and the end of the limiting rod away from the support frame can be movably connected with the circular hole groove and snapped with the strip groove. The combined use of the limiting rod and the composite groove can ensure that the advertising board is stably installed on the surface of the support frame and maintain the conditions for flexible disassembly.

The publicity board 6 is movably installed on the surface of the two support frames 2. The front and rear ends of the publicity board 6 are provided with composite clearance grooves. The front and rear ends of the support frame 2 are installed with limit rods 9. During the installation of the publicity board 6 on the surface of the support frame 2, the composite groove 10 first fits with the limit rod 9 to make clearance and then fits with the limit rod 9 to slide and limit. The composite groove 10 is composed of a strip groove and a round hole groove that communicates with its own space. The limit rod 9 has a T-shaped structure, and the end of the limit rod 9 away from the support frame 2 can be movably fitted with the round hole groove and snapped with the strip groove. The combined use of the limit rod 9 and the composite groove 10 can ensure that the publicity board 6 is stably installed on the surface of the support frame 2 and maintain the condition of flexible disassembly.

[0029] The base 1 has two transmission gears 3, two opposing straight gear plates 4, and a double cam transmission assembly 5 in its middle. The two opposing straight gear plates 4 are slidably mounted on both sides of the top of the base 1 and can be driven by the double cam transmission assembly 5. The double cam transmission assembly 5 includes an adjusting shaft 51. One end of the adjusting shaft 51 is fitted into the top structure of the base 1 through a bearing. The middle of the adjusting shaft 51 is equipped with a double cam plate 52 that can be driven by the other end of the two straight gear plates 4. The top of the base 1 has a threaded hole. The double cam plate 52 has an arc-shaped clearance groove inside that can be aligned with the threaded hole. The double cam plate 52 and the base 1 are connected by a threaded hole. The base 1 can be limited and installed by means of screws passing through the arc-shaped clearance groove and threaded to the threaded hole. The double cam transmission assembly 5 can not only push and drive the two straight tooth plates 4 synchronously, but also lock and limit the base 1 to ensure the stability of the two straight tooth plates 4 and the two transmission gears 3 after adjustment. The top of the adjusting shaft 51 is equipped with a limit frame plate 53 and a torsion plate 54. The two sides of the bottom of the limit frame plate 53 can respectively fit and connect to the top of one end of the two straight tooth plates 4. The number of torsion plates 54 is not less than two and they are evenly distributed along the circumference of the adjusting shaft 51, which facilitates the application of force to the adjusting shaft 51.

[0030] Limiting springs 7 are installed on one end of each of the two straight toothed plates 4, and one end of the limiting springs 7 is fixedly connected to a limiting seat installed on the top of the base 1.

One end of the two straight toothed plates 4 is a semi-circular structure to facilitate subsequent top pressure. The bottom inner side of the two straight toothed plates 4 is respectively engaged with a slide rail 12 installed on the top of the base 1.

[0031] In this specific embodiment: when it is needed, the screws between the double cam plate 52 and the base 1 can be unscrewed first. Then, the adjusting shaft 51 is twisted by multiple torsion plates 54 and the double cam plate 52 is driven to press the two straight tooth plates 4 simultaneously. The limiting frame plate 53 can press down and constrain the two straight tooth plates 4.

[0032] After being pressed and moved, the two straight toothed plates 4 will synchronously mesh with their respective transmission gears 3, and the limiting springs 7 associated with the two straight toothed plates 4 will be compressed and deformed, thereby causing the two support frames 2 to rotate and rise under the support of the base 1. After the two support frames 2 have rotated and risen to the specified angle, the turning force on the adjusting shaft 51 is maintained, the locking screw is reset, and then the two ends of the reinforcing crank 11 are respectively fitted to the top structure of the two support frames 2 to ensure the stability of the two tilted support frames 2.

[0033] After the two support frames 2 are stable, install the two advertising boards 6 on the surfaces of the two support frames 2 respectively. Specifically, the composite groove 10 inside the advertising board 6 is first movably connected to the limiting rod 9 on the surface of the corresponding support frame 2. Then, move the advertising board 6 down so that the composite groove 10 and the limiting rod 9 are engaged, which can ensure that the advertising board 6 is stably installed on the surface of the support frame 2. Similarly, the remaining advertising board 6 is installed with the corresponding support frame 2 in the same way. After completion, the two advertising boards 6 will provide advertising support surfaces for writing or pasting promotional materials.

[0034] When the entire device needs to be moved, the reinforcing crank 11 can be separated first. Then, the screws between the double cam plate 52 and the base 1 can be removed. After that, the two advertising plates 6 are pressed together, so that the two support frames 2 are staggered and rotated on the top of the base 1 until they can no longer rotate. The two straight tooth plates 4 are pressed against the double cam transmission assembly 5 under the passive meshing of the corresponding transmission gears 3 to reset. Then, the locking screws are reset, so that the entire device can be partially stored, making it convenient to unfold and use again. Example
