DETAILED DESCRIPTION

[0025] In the following, the application will be further described in conjunction with specific embodiments, and it should be noted that the following described embodiments or technical features can be combined to form new embodiments without conflict.

[0026] In the description of the application, it should be noted that for orientation words, such as terms "center", "transverse", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. The orientation and positional relationship shown in the drawing is based on the orientation or positional relationship shown in the drawing, and is only for the convenience of describing the application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and cannot be understood as limiting the specific protection scope of the application.

[0027] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0028] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0029] One of the preferred embodiments of this application is as follows: Figures 1 to 6 As shown, a dust cover durability test device includes a frame 1, a first telescopic device 2, and a second telescopic device 3. A placement plate 10 is provided in the middle of the frame 1, with the first telescopic device 2 and the second telescopic device 3 mounted above and below the placement plate 10, respectively. The second telescopic device 2 can be extended upward through the placement plate 10 to position and fit the dust cover 6 to be tested. The first telescopic device 2 can press down on the top of the positioned dust cover 6 and, through reciprocating motion, drive the dust cover 6 to repeatedly compress and deform relative to the placement plate 10.

[0030] It should be noted that the primary function of the dust cover 6 is to prevent foreign matter such as dust and metal shavings from entering the interior of the device, protecting the device's delicate components from damage. It also protects the surface of the item from corrosion and damage, thereby extending the item's service life. Most commercially available experimental devices for the dust cover 6 test its use in extreme weather conditions, neglecting factors such as the dust cover's folding resistance. However, these factors are also crucial.

[0031] Therefore, in this embodiment, a first telescopic device 2 and a second telescopic device 3 are disposed opposite to each other on the frame 1. The first telescopic device 2 and the second telescopic device 3 can use different driving modes to compress the dust cover 6. The first telescopic device 2 and the second telescopic device 3 are used to perform a high-strength compression test on the dust cover 6.

[0032] It should be known that the first telescopic device 2 and the second telescopic device 3 are arranged relative to the frame 1 along the height direction of the frame 1, and the dust cover 6 is compressed by the first telescopic device 2 and the second telescopic device 3 being driven synchronously or relatively. Based on the different compression methods of the first telescopic device 2 and the second telescopic device 3 being driven synchronously or relatively, the specific structures of the first telescopic device 2 and the second telescopic device 3 are also different. For the sake of ease of understanding, the following can be explained through two specific embodiments.

[0033] Example 1:

[0034] like Figure 1 and Figure 2 As shown, a placement plate 10 is provided in the middle of the frame 1. A first telescopic device 2 and a second telescopic device 3 are mounted relative to the placement plate 10 along its height. The second telescopic device 2 can pass through the placement plate 10 and engage with dust covers 6 of different sizes. The first telescopic device 2 can counteract the first telescopic device 3 to synchronize movement along the height of the placement plate 10, thereby repeatedly compressing dust covers 6 of different sizes.

[0035] It will be appreciated that one of the essential features of this embodiment is that the first and second telescopic devices 2, 3 are mounted relative to the placement plate 10 along its height, and that the second telescopic device 2 can be inserted through the placement plate 10 and the dust cover 6. As can be seen from the above, the second telescopic device 2 can be inserted through the placement plate 10 and can be inserted into dust covers 6 of different sizes. Therefore, the placement plate 10 must be provided with an opening 100 to allow the second telescopic device 2 to pass smoothly through the placement plate 10.

[0036] Therefore, in this embodiment, Figure 1 As shown, the first and second telescopic devices 2 and 3 are mounted relative to each other above and below the placement plate 10, along its height. The placement plate 10 is provided with an open slot 100, through which the second telescopic device 3 can pass and engage with the dust cover 6, with the bottom of the dust cover 6 abutting against the top of the placement plate 10. The second telescopic device 3 can move vertically upward, abutting against the first telescopic device 2. Consequently, the first and second telescopic devices 2 and 3 repeatedly compress the dust cover 6 through their synchronized vertical motion.

[0037] Specifically, such as Figures 1 to 5 As shown, the first telescopic device 2 includes a first driving member 20 and a first pressing plate 21 installed at the driving end of the first driving member 20, and the second telescopic device 3 includes a second driving member 30, a second pressing plate 31, and a positioning column 32 detachably mounted on the top of the second pressing plate 31. The bottom of the second pressing plate 31 is fixedly connected to the driving end of the second driving member 30, and the positioning column 32 extends out of the open slot 100 away from the end connected to the second pressing plate 31 and is sleeved on the dust cover 6, and the bottom end of the dust cover 6 and the top of the placement plate 10 are abutted. Under the drive of the second driving member 30, the second pressing plate 31 can carry the positioning column 32 to move vertically upward until the positioning column 32 is away from the end connected to the second pressing plate 31 and abuts against the first pressing plate 21, so that the top of the dust cover 6 and the first pressing plate 21 abut against each other. The first driving member 20 and the second driving member 30 can repeatedly compress the dust cover 6 by synchronously driving the first pressing plate 21 and the second pressing plate 31 in the vertical direction after abutment.

[0038] It should be noted that in this embodiment, the second telescopic device 2 can be connected to dust covers 6 of different sizes, that is, the positioning post 32 can be connected to dust covers 6 of different sizes, and therefore the size of the positioning post 32 must also be set in a variety of ways. However, in this embodiment, the positioning post 32 is connected to the dust cover 6 by extending one end through the open slot 100, so the size of the open slot 100 is also a necessary condition. Therefore, in this embodiment, the size of the open slot 100 corresponds to the largest size model of the positioning post 32.

[0039] It should also be noted that, as can be seen from the above, there is at least one positioning column 32, that is, the first telescopic device 2 and the second telescopic device 3 can perform a compression test on at least one dust cover 6; however, considering its work efficiency and other reasons, the work efficiency of the equipment operation to perform a compression test on only a single dust cover 6 is too low, and may even not be able to bear the cost of its equipment operation. Considering the above problems, Figure 1 As shown, in this embodiment, four positioning posts 32 are provided. The number of the positioning posts 32 is limited only in this embodiment, and the specific number of the positioning posts 32 can be set according to the actual needs of those skilled in the art.

[0040] In this embodiment, due to the provision of the opening slot 100, the dust cover 6 cannot abut against the placement plate 10, and thus compression cannot be completed. Therefore, in this embodiment, the opening of the opening slot 100 needs to be controlled. There are multiple specific control methods, including but not limited to the following two.

[0041] Method 1: A blocking plate is provided on the placement plate 10. Multiple blocking plates are provided, each with slots adapted to accommodate positioning posts 32 of varying sizes. The minimum dimension of the blocking plate is larger than the size of the opening 100, ensuring that the bottom of the dust cover 6 abuts the top of the blocking plate.

[0042] Method 2: If Figure 1 As shown, an adjustment assembly 4 is also mounted on the placement plate 10. This adjustment assembly 4 can adjust the opening of the opening slot 100 according to different types of positioning posts 32, and the lower end of the dust cover 6 abuts against the adjustment assembly 4. The adjustment assembly 4 includes a pair of backing plates 40 positioned relative to the opening slot 100. Each backing plate 40 is provided with a notch 400 corresponding to the opening slot 100. The relative distance between the two backing plates 40 is adjusted to adjust the opening of the notch 400 relative to the opening slot 100.

[0043] It should be noted that both of the above-mentioned two setting methods can meet the requirements of this application, and those skilled in the art can make their own choices based on actual needs; in this embodiment, the above-mentioned method 2 is preferably adopted.

[0044] It is understandable that the two methods mentioned above actually have the same principle. Both can be fitted with positioning posts 32 of different sizes to limit the opening of the opening slot 100 so that the dust cover 6 can offset it. The difference is that the blocking plate described in method one needs to be replaced according to the different sizes of its positioning posts 32, which may be relatively troublesome in a high-intensity working environment, and the independent blocking plate may be lost. Method two, on the other hand, is to adjust the opening of the opening slot 100 by adjusting the adjustment component 4. In essence, it is still fixed on the placement plate 10. Compared with method one, its structure is relatively more stable, so the above-mentioned method two is preferably adopted in this embodiment. At the same time, in order to allow the positioning post 32 to smoothly pass through the adjustment component 4, the shape of its notch 400 is also a key factor. In this embodiment, the shape of the notch 400 is set to be semicircular or V-shaped.

[0045] In this embodiment, Figure 1 As shown, to stabilize the mounting structure of the second telescopic device 3, a base plate 11 is provided at the bottom of the frame 1, and the second driving member 30 is fixedly mounted on the base plate 11. At the same time, to prevent the first and second telescopic devices 2, 3 from over-compressing the dust cover 6, a limit post 5 is provided on the first pressure plate 21 to limit the range of motion of the first pressure plate 21 in the vertical direction.

[0046] Example 2:

[0047] Compared with the first embodiment, the difference of the second embodiment is that: Figure 6 As shown, a through hole is provided on the first pressure plate 21. After the second pressure plate 21 moves vertically upward and abuts against the placement plate 10, it remains stationary, while the first pressure plate 21 moves vertically downward, and at the same time completes the penetration through its through hole and the positioning column 32, and then the first pressure plate 21 moves back and forth in the vertical direction to compress its dust cover 6.

[0048] It will be appreciated that in this embodiment, the second telescopic device 3 similarly passes through the open slot 100 and engages with the dust cover 6. The second telescopic device 3 also moves vertically upward, but remains stationary after contacting the placement plate 10. The first telescopic device 2 can move vertically downward, intersecting the second telescopic device 3. The dust cover 6 is repeatedly compressed by the vertical reciprocating motion of the first telescopic device 2 relative to the second telescopic device 3.

[0049] Specifically, in this embodiment, the first telescopic device 2 includes a first driving member 20 and a first pressure plate 21 mounted on the driving end of the first driving member 20. The second telescopic device 3 includes a second driving member 30, a second pressure plate 31, and a positioning post 32 detachably mounted on the top of the second pressure plate 31. The bottom of the second pressure plate 31 is fixedly connected to the driving end of the second driving member 30. The positioning post 32 extends out of the open slot 100 at the end away from the second pressure plate 31 and is engaged with the dust cover 6. The second pressure plate 31 can be driven by the second driving member 30 to move vertically upward with the positioning post 32 until the second pressure plate 31 and the placement plate 100 abut against each other and then remain stationary. The first pressure plate 21 is provided with a through-hole. Under the drive of the first driving member 20, the first pressure plate 21 can move vertically downward, allowing the positioning post 32 to pass through the through-hole, thereby abutting the top of the dust cover 6 against the first pressure plate 21. The first driving member 20 can drive the first pressure plate 21, after passing through the positioning post 32, to reciprocate vertically relative to the second pressure plate 31.

[0050] It is understood that the principle is the same as in the first embodiment, but in this embodiment, the positioning post 32 also needs to pass through the first pressure plate 21, so a through-hole is provided in the first pressure plate 21. The principle of providing the through-hole is the same as that of providing the opening 100 in the first embodiment. The bottom end of the dust cover 6 abuts against the second pressure plate 31, but in order to complete the compression, the top end of the dust cover 6 also needs to abut against the first pressure plate 21.

[0051] Therefore, in this embodiment, the first pressure plate 21 is also provided with an adjustment assembly 4. The adjustment assembly 4 includes a pair of pads 40 positioned relative to the through-hole. Each pad 40 is provided with a notch 400 corresponding to the through-hole. The operating principle is the same as that described in the first embodiment. Furthermore, the shape of the notch 400 in this embodiment is the same as that in the first embodiment.

[0052] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. These changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
