Description

Technical fields:

[0001] This utility model relates to the field of a novel wind resistance testing device for street light heads. Background technology:

[0002] Chinese utility model patent specification CN216524719U discloses a street lamp head wind resistance testing device, including a base plate, an adjusting plate, and a suspension arm for fixed installation on a wall. One end of the suspension arm is a fixed end welded to the front of the adjusting plate, and the other end is a free end extending away from the adjusting plate for suspending the street lamp head under test. The base plate has a base plate hinge, and the back of the adjusting plate has an adjusting plate hinge, which is hinged to the base plate hinge. The adjusting plate also has a set screw threadedly connected to the adjusting plate, the end of which passes through the adjusting plate and presses tightly against the base plate. The adjusting plate hinge is located above the fixed end of the suspension arm, while the set screw is located below the fixed end of the suspension arm. However, the suspension arm disclosed in the above patent only adjusts the angle of the suspension arm by changing the forward and backward rotation of the adjusting plate according to the set screw, and cannot rotate left and right to meet the simulation test of the real use environment. Utility model content:

[0003] The purpose of this utility model is to provide a new type of street light head wind resistance testing device to solve the problem in the above-mentioned background art where the adjustment plate of the street light head wind resistance testing device can only rotate forward and backward, but cannot rotate left and right to meet the simulation test of real use environment.

[0004] The objective of this utility model is achieved through the following technical solution.

[0005] The purpose of this utility model is to provide a novel wind resistance testing device for street light heads, including a base plate, a rotating disk, and an adjusting plate. The rotating disk has a first hinge portion, and the adjusting plate has a second hinge portion at its rear side. The first hinge portion and the second hinge portion are hinged together. A sleeve is provided on the adjusting plate, and a first through hole is provided at the bottom of the sleeve. An adjustable screw is installed in the first through hole. The rotating disk is mounted on the base plate and rotates on the base plate. A first gear tooth is provided around the periphery of the rotating disk. A limiting mechanism is fixed on the base plate. The limiting mechanism includes a housing, a sliding member, and a spring. The sliding member slides inside the housing, and its end extends outside the housing. The spring is located between the sliding member and the housing. A second gear tooth is provided at the end of the sliding member. The spring pushes the sliding member to extend, causing the first gear tooth to engage with the second gear tooth to restrict the rotation of the rotating disk. A push rod is provided on the sliding member, extending from inside the housing.

[0006] Furthermore, a convex circle is provided on the base plate, and the rotating disk is fitted onto the convex circle.

[0009] Furthermore, a bearing is provided between the second through hole and the protrusion.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] 1) This utility model describes a novel wind resistance testing device for street light heads, comprising a base plate, a rotating disk, and an adjusting plate. The rotating disk has a first hinge portion, and the adjusting plate has a second hinge portion at its rear side. The first hinge portion and the second hinge portion are hinged together. A sleeve is provided on the adjusting plate, and a first through hole is provided at the bottom of the sleeve. An adjustable, protruding screw is installed in the first through hole. The rotating disk is mounted on the base plate and rotates on the base plate. A first gear tooth is provided around the periphery of the rotating disk.

[0020] like Figures 1 to 4As shown, this embodiment provides a novel wind resistance testing device for street light heads, including a base plate 1, a rotating disk 2, and an adjusting plate 3. The base plate 1 is mounted and fixed to a wall. The rotating disk 2 is provided with a first hinge part 21, and the adjusting plate 3 is provided with a second hinge part 31 at its rear side. The first hinge part 21 and the second hinge part 31 are hinged together, allowing for front-to-back angle adjustment. The adjusting plate 3 is provided with a sleeve 32, on which the street light head is mounted. The bottom of the sleeve of the adjusting plate 3 is provided with a first through hole 33, in which an adjustable screw 34 is installed. The screw 34 extends and retracts within the first through hole 33, supporting the rotating disk 2, thus enabling front-to-back angle adjustment. The rotating disk 2 is mounted on the base plate 1 and rotates on the base plate 1. The outer periphery of the rotating disk 2 is provided with a first gear tooth 22. A limiting mechanism 4 is fixed on the base plate 1. The device includes a housing 41, a slider 42, and a spring 43. The slider 42 slides inside the housing 41, with its end extending outside the housing 41. The spring 43 is located between the slider 42 and the housing 41. The end of the slider 42 is provided with a second gear tooth 421. The spring 43 pushes the slider 42 to extend, causing the first gear tooth 22 to mesh with the second gear tooth 421, restricting the rotation of the rotating disk 2. A push rod 422 is provided on the slider 42, extending from inside the housing 41. During use, the first gear tooth 22 meshes with the second gear tooth 421, restricting the rotation of the rotating disk 2. When the slider 42 moves downward, the spring 43 is compressed, causing the first gear tooth 22 and the second gear tooth 421 to move away, allowing the rotating disk 2 to rotate freely. This allows for rotation not only forward and backward but also left and right, meeting the requirements of simulated real-world usage environments.

[0021] As an optional embodiment, the base plate 1 is provided with a convex circle 11, and the rotating disk 2 is fitted on the convex circle 11, so that the rotating disk 2 will not wobble and has better stability.

[0022] As an optional embodiment, the end of the screw 34 is provided with a rubber sleeve 341, which presses against the rotating disk 2. When the rubber sleeve 341 contacts the rotating disk 2, it can avoid frictional contact between metals, which can easily cause noise.

[0023] As an optional embodiment, a second through hole 12 is provided on the convex circle 11 of the base plate 1, and a protruding post 23 is provided in the rotating disk 2. The protruding post 23 is inserted into the second through hole 12 for locking. It can be riveted or fixed with screws.

[0024] As an optional embodiment, a bearing is provided between the second through hole 12 and the protrusion 23, and the bearing can improve the rotation.

[0025] The existing street light head wind resistance testing device has an adjustment plate that rotates forward and backward but cannot rotate left and right to meet the simulation test requirements of real-world usage environments. This paper provides a new type of street light head wind resistance testing device. A rotating disk 2 is mounted on a base plate 1 and rotates on the base plate 1. The rotating disk 2 has a first gear tooth 22 on its periphery. A limit mechanism 4 is fixed on the base plate 1. A second gear tooth 421 is provided at the end of a sliding member 42. A spring 43 pushes the sliding member 42 to extend, causing the first gear tooth 22 to mesh with the second gear tooth 421, restricting the rotation of the rotating disk 2. When the sliding member 42 moves downward, the spring 43 compresses, causing the first gear tooth 22 and the second gear tooth 421 to move away, allowing the rotating disk 2 to rotate freely. This allows for not only forward and backward rotation but also left and right rotation to meet the simulation test requirements of real-world usage environments.

[0026] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
