Description

Technical Field

[0001] This invention relates to the field of damping shock absorber technology, and particularly to a shock absorber with a cylinder made of zinc-aluminum-magnesium steel. Background Technology

[0002] In the photovoltaic industry, the use of photovoltaic tracking brackets has become the norm in order to improve the light-gathering efficiency of photovoltaic panels. In order to improve the wind resistance of photovoltaic tracking brackets, shock absorbers are configured to dampen and reduce vibration. When subjected to wind vibration, the damping force of the shock absorber itself provides damping for the photovoltaic tracking bracket, thereby reducing the vibration of the bracket.

[0003] Currently, most damping shock absorbers used are made of ordinary carbon steel. When in use, anti-rust paint is sprayed on the surface of the damping shock absorber. However, the anti-rust paint has limited rust prevention effect and cannot fully cover the damper cylinder. In high temperature, high humidity and coastal areas, the shock absorber will still rust.

[0004] Zinc-aluminum-magnesium steel has excellent rust-proof properties, so using zinc-aluminum-magnesium steel to protect shock absorbers can achieve a very good rust-proof effect. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems by providing a shock absorber with a cylinder made of zinc-aluminum-magnesium steel.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a shock absorber with a cylinder made of zinc-aluminum-magnesium steel, including a shock absorber body and a zinc-aluminum-magnesium steel protective cylinder. The protective cylinder includes a first cylinder and a second cylinder that are fitted together. The two ends of the first cylinder and the second cylinder are detachably and fixedly connected to the two ends of the shock absorber body, respectively.

[0007] Furthermore, both ends of the shock absorber body are coaxially provided with connecting parts. One of the connecting parts and the shock absorber body is coaxially provided with a threaded hole, and the other is provided with a screw. The ends of the first cylinder and the second cylinder that are far apart from each other are provided with end plates, and the end plates are provided with mating holes for the screw to pass through.

[0008] Furthermore, both the first cylinder and the second cylinder, at their ends that are far apart from each other, are provided with positioning sections that fit and engage with the shock absorber body.

[0009] Furthermore, the connector includes a limiting surface facing the shock absorber body; when the connector is fixedly connected to the shock absorber body, the limiting surface engages with the end plate through a pressing and limiting fit.

[0010] Furthermore, the limiting surface is sealed to the surface of the end plate.

[0011] Furthermore, the first cylinder includes a first mating section connected to the end of the positioning section, and the second cylinder includes a second mating section sleeved outside the first mating section. An annular scraper is provided on the outer circumferential surface of the first mating section, and the annular scraper includes an elastic scraping end that mates with the inner circumferential surface of the second mating section.

[0012] Furthermore, the outer peripheral surface of the first mating section is provided with an annular positioning groove, and the scraping component is sleeved in the positioning groove.

[0013] This utility model discloses a shock absorber with a cylinder made of zinc-aluminum-magnesium steel, which has the following advantages compared with the prior art in the field of damping shock absorber technology: the shock absorber body can be protected by the zinc-aluminum-magnesium steel protective sleeve, thereby achieving the effect of rust prevention. The shock absorber body includes a zinc-aluminum-magnesium steel protective sleeve. The protective sleeve includes a first cylinder and a second cylinder that are fitted together.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] Example 1

[0025] Please refer to Figure 1-5 As a specific implementation method, the technical solution of this utility model is as follows: a shock absorber with a cylinder made of zinc-aluminum-magnesium steel, including a shock absorber body 2 and a zinc-aluminum-magnesium steel protective cylinder 1. The protective cylinder 1 includes a first cylinder 11 and a second cylinder 10 that are fitted together. The two ends of the first cylinder 11 and the second cylinder 10 are respectively detachably and fixedly connected to the two ends of the shock absorber body 2.

[0026] Specifically, by fitting a first cylinder 11 and a second cylinder 10 around the outside of the shock absorber body 2, the first cylinder 11 and the second cylinder 10 are made of zinc-aluminum-magnesium steel. In this way, the shock absorber body 2 can be protected by the protective cylinder, thereby achieving the effect of rust prevention.

[0027] As a preferred embodiment, in some embodiments, the cylinder of the shock absorber is also made of zinc-aluminum-magnesium steel, which can achieve better protection.

[0028] Furthermore, as a specific implementation method, refer to Figure 1 - Figure 3Both ends of the shock absorber body 2 are coaxially provided with connecting parts 21. One of the connecting parts 21 and the shock absorber body 2 is coaxially provided with a threaded hole, and the other is provided with a screw 20. The ends of the first cylinder 11 and the second cylinder 10 that are far apart from each other are provided with end plates, and the end plates are provided with mating holes for the screw 20 to pass through. Specifically, the screw 20 is provided at both ends of the shock absorber body 2. The mating holes include a first mating hole 104 provided on the end plate of the first cylinder 11 and a second mating hole 112 provided on the end plate of the second cylinder 10. When installing the first cylinder 11 and the second cylinder 10, the screws 20 at both ends are passed through the first mating hole 104 and the second mating hole 112 respectively, and then the connecting parts 21 are threaded onto the screws 20. The connecting parts 21 limit the positioning of the first cylinder 11 and the second cylinder 10.

[0029] Furthermore, as a specific implementation, each of the first cylinder 11 and the second cylinder 10, at their ends furthest from each other, is provided with a positioning section that engages with and positions the shock absorber body 2. To better ensure the positioning accuracy of the first cylinder 11 and the second cylinder 10 relative to the shock absorber body 2, refer to... Figure 6 - Figure 8 The first cylinder 11 includes a first positioning section 111 and a first mating section 113 disposed at the end of the first positioning section 111. The second cylinder 10 includes a second positioning section 106 and a second mating section 105. The shock absorber body 2 includes a first body 22 and a second body 23. During assembly, the first cylinder 11 is fitted onto the end of the second body 23. The cylindrical inner circumferential surface of the first mating section 113 is guided and positioned to engage with the outer circumferential surface of the second body 23. The first mating section 113 can be fitted onto the outer circumferential surface of the second body 23, and the inner circumferential surface of the first mating section 113 is slidably engaged with the outer circumferential surface of the second body 23. The second positioning section 106 of the second cylinder 10 can be fitted onto the end of the second body 23 and positioned to engage. The second mating section 105 partially overlaps with the first mating section 113 and wraps around the periphery of the first mating section 113. During use, the first body 22 faces upward and the second body 23 faces downward to prevent rainwater from entering the second mating section 105.

[0030] Furthermore, as a specific implementation method, refer to Figure 2 The connector 21 includes a limiting surface 210 facing the shock absorber body 2; when the connector 21 is fixedly connected to the shock absorber body 2, the limiting surface 210 presses and limits the end plate.

[0031] Further, refer to Figure 2The limiting surface 210 is in a sealing fit with the surface of the end plate. When the connector 21 is threaded onto the screw 20, the pressure of the threaded connection forces the limiting surface 210 into contact with the end face of the end plate, thereby forming a sealing fit. In some embodiments, an aluminum or copper sealing gasket can also be fitted between the end plate and the limiting surface 210 to improve the sealing performance.

[0032] Example 2

[0033] Reference Figure 6 - Figure 8 As a specific implementation method, the technical solution of this utility model is as follows: Further, as a preferred implementation method, the difference from Embodiment 1 is that: the first cylinder 11 includes a first mating section 113 connected to the end of the positioning section, the second cylinder 10 includes a second mating section 105 sleeved outside the first mating section 113, and an annular scraping member 12 is provided on the outer peripheral surface of the first mating section 113. The annular scraping member 12 includes an elastic scraping end 121 that mates with the inner peripheral surface of the second mating section 105.

[0034] Specifically, the wiping component 12 is made of rubber or plastic and is an umbrella-shaped annular component. The end of the umbrella-shaped annular component is the wiping end 121. The annular component is elastic. (Refer to...) Figure 5 In its free state, the scraping end 121 can contact the inner circumferential surface of the second mating section 105 of the second cylinder 10 under its own elastic force. With this arrangement, when the shock absorber is squeezed and extended, the first cylinder 11 and the second cylinder 10 move relative to each other in the axial direction. When they move closer to each other, the air inside the second cylinder 10 is squeezed out from between the scraping end 121 and the second mating section 105. When rainwater splashes into the area below the scraping end 121 in rainy weather, the airflow can blow the rainwater outward, reducing the probability of rainwater entering the interior of the second mating section 105 and achieving a better protective effect. When they move away from each other, the scraping end 121 is in contact with the inner circumferential surface of the second mating section 105 to scrape it.

[0035] Furthermore, as a preferred embodiment, refer to Figure 4A vent hole 102 is provided on the side wall of the second mating section 105 near the first positioning section 111. A one-way valve plate 103 is provided at the vent hole 102. The one-way valve plate 103 is made of rubber. A blocking member 101 is provided on the outer peripheral surface of the second mating section 105 to block the vent hole 102. With this arrangement, when the first cylinder 11 and the second cylinder 10 move relative to each other in the axial direction and move closer to each other, the one-way valve plate 103 blocks the vent hole 102, and the gas cannot flow out from the vent hole 102. At this time, the air inside the second cylinder 10 is squeezed out from between the scraping end 121 and the second mating section 105. In rainy weather, the scraping end... When rainwater splashes into the area below 121, the airflow can blow the rainwater outward, reducing the probability of rainwater entering the interior of the second mating section 105. As the scraping end 121 moves away from the second mating section 105, it scrapes against the inner circumferential surface of the second mating section 105, creating a certain negative pressure inside the second mating section 105. At this time, the one-way valve plate 103 opens the vent hole 102, allowing external air to flow into the second mating section 105. The baffle plate can block the rainwater from entering through the vent hole 102, thereby preventing airflow from entering through the gap between the scraping end 121 and the second mating section 105. It can also prevent the scraping end 121 from flipping over due to airflow impact, thus losing its protective effect.

[0036] For details, please refer to Figure 4 The upper end of the one-way valve plate 103 is bonded and fixed to the inner wall of the second cylinder 10, while the lower end is not fixed, thereby achieving the purpose of one-way restriction of airflow through the vent hole 102. This structure is a common technical means in the field of one-way valves, and those skilled in the art should understand it.

[0037] Furthermore, the outer peripheral surface of the first mating section 113 is provided with an annular positioning groove 110, and the scraper 12 is fitted into the positioning groove 110. This arrangement facilitates the installation and removal of the scraper 12, and makes it easy to replace.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
