[0044] The terms "including," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, which includes not only the listed elements but also other elements not expressly listed. (Specific combination) Figures 1 to 5 The following describes an oil splash prevention device for a test bench according to this application.

[0045] like Figure 1 As shown, this application provides an oil splash prevention device for a test bench, comprising: a guiding device including a first guide rail 11 and a second guide rail 12 that are vertically and parallel to each other on the test bench; and a protective cover 2 having a first slider 51 and a second slider 52 that cooperate with the first guide rail 11 and the second guide rail 12. A first limiting mechanism is provided between the first slider 51 and the first guide rail 11 to limit the relative position between the first slider 51 and the first guide rail 11, and a second limiting mechanism is provided between the second slider 52 and the second guide rail 12 to limit the relative position between the second slider 52 and the second guide rail 12.

[0046] In actual use, the protective cover 2 slides on the first guide rail 11 and the second guide rail 12. When the protective cover 2 moves to the set position, the first limit mechanism and the second limit mechanism limit the position of the protective cover 2 on the first guide rail 11 and the second guide rail 12, which can prevent oil from splashing out in the working area of ​​the test bench and protect the personal safety of the operator.

[0047] like Figures 1 to 3As shown in the specific example provided in this application, the protective cover 2 includes a cover plate 21 and an upper side plate 22, a lower side plate, a left side plate 24, and a right side plate 23 arranged around the cover plate 21 and connected in sequence. The cover plate 21, the upper side plate 22, the lower side plate, the left side plate 24, and the right side plate 23 form a rectangular cover structure with an opening on one side. In this embodiment, the opening of the cover structure faces the side of the first guide rail 11 and the second guide rail 12, and the cover plate 21 and the opening side of the cover are opposite sides. It should be noted that the above is a specific structural example of the protective cover 2 provided in this application. In other embodiments, the protective cover 2 may have only one protective plate to block oil splashes in the working area of ​​the test bench. Therefore, this application does not limit the specific structure of the protective cover 2. Any specific structure of the protective cover 2 that can be moved to the test area of ​​the test bench via the first guide rail 11 and the second guide rail 12 to block oil splashes is within the protection scope of this application.

[0048] like Figures 2 to 5 As shown in a specific example provided in this application, the first guide rail 11 and the second guide rail 12 are each provided with a groove 9 on the side facing the protective cover 2; the first slider 51 and the second slider 52 are each provided with a slider 7, which slides within the corresponding groove 9. Specifically, in this embodiment, the first slider 51 and the second slider 52 are respectively disposed on the left side plate 24 and the right side plate 23. The sliders 7 on the first slider 51 and the second slider 52 slide within the grooves 9 on the corresponding first guide rail 11 and the second guide rail 12, respectively, and the two sliders 7 on the protective cover 2 enable the protective cover 2 to operate stably.

[0049] like Figures 3 to 5 As shown in the specific example provided in this application, the first guide rail 11 and the second guide rail 12 are respectively provided with a vertical and parallel first baffle 61 and a second baffle 62; a slide 902 connecting the first baffle 61 and the second baffle 62 to the slide groove 9 is provided, and a limiting space 901 is provided between the first baffle 61 and the second baffle 62 and the opposite slide groove 9 to limit the movement of the slider 7 in a direction perpendicular to the first guide rail 11 or the second guide rail 12; the slider 7 has a connecting member 72 for sliding within the slide 902. The first limiting mechanism includes a plurality of limiting holes 8 vertically and evenly distributed at the bottom of the slide groove 9 and at least one limiting rod 71 provided on the slider 7; when the protective cover 2 is moved to the desired position, the limiting rod 71 is located in the corresponding limiting hole 8. It should be noted that in this embodiment, the second limiting mechanism is the same as the first limiting mechanism.

[0050] In actual use, firstly, pull the protective cover 2 outward, so that the protective cover 2 moves away from the first guide rail 11 and the second guide rail 12, that is, the slider 7 moves within the limiting space 901, so that the limiting rod 71 disengages from the limiting hole 8. Then, the operator moves the protective cover 2, that is, the slider 7 on the protective cover 2 slides within the groove 9 on the first guide rail 11 and the second guide rail 12 until the moving cover moves to the desired position. Push the protective cover 2 closer to the first guide rail 11 and the second guide rail 12, so that the limiting rod 71 enters the limiting hole 8, which is used to limit the movement of the protective cover 2 and ensure that the protective cover 2 blocks the oil splash in the working area of ​​the test bench.

[0051] During the use of the aforementioned oil splash prevention device, the operator moves the protective cover 2. Due to the large weight of the protective cover 2, actual operation is often inconvenient and poses a safety hazard. Therefore, if... Figures 1 to 3 As shown, the oil splash prevention device for the test bench of this application also includes a balancer assembly 31. The balancer assembly 31 includes a mounting base 32 and a balancer 31. The mounting base 32 is installed on the top of the protective cover 2. The balancer 31 is installed on a fixing member above the protective cover 2, and the steel cable 311 of the balancer 31 is hooked to the mounting base 32. Specifically, in this embodiment, the mounting base 32 is a lifting ring, which facilitates the connection of the steel cable 311 of the balancer 31. The balancer 31 is installed on the ceiling above the protective cover 2 to ensure the stable operation of the balancer 31. It should also be noted that in other embodiments, the test bench located above the protective cover 2 has a fixing rod, and the balancer 31 is installed on the fixing rod. Therefore, this application does not limit the installation position of the balancer 31, as long as the balancer 31 can balance the weight of the protective cover 2 itself above the protective cover 2. In actual use, the balancer 31 can balance the weight of the protective cover 2, making it easy for operators to move the protective cover 2 and avoiding safety hazards caused by the weight of the protective cover 2 itself.

[0052] Furthermore, the oil splash prevention device for the test bench in this application also includes an alignment mechanism, which includes a stop block disposed on the first guide rail 11 and / or the second guide rail 12. In actual use, when the protective cover 2 is moved to the set position, the stop block limits the continued movement of the protective cover 2, preventing excessive movement and ensuring that the protective cover 2 blocks oil splashes within the working area of ​​the test bench. It should be noted that the protective cover 2 is equipped with a warning light to remind the operator that the protective cover 2 has moved to the desired position. It is also worth mentioning that in other embodiments, a stepper motor drives the protective cover 2 to slide on the first guide rail 11 and the second guide rail 12. When the protective cover 2 moves to the set area, a distance sensor ensures accurate movement of the protective cover 2.

[0053] like Figure 1 and Figure 2As shown in a specific example provided in this application, the oil splash prevention device of the test bench also includes a handle 4, which is disposed on the outer side of the protective cover 2. Specifically, in this embodiment, the handle 4 is disposed on the cover plate 21, facilitating the operator to move the protective cover 2 on the first guide rail 11 and the second guide rail 12. In other embodiments, the handle 4 can be disposed on any one of the upper side plate 22, lower side plate, left side plate 24, and right side plate 23, depending on the actual situation, and is not limited here.

[0054] like Figure 1 and Figure 2 As shown in a specific example provided in this application, the protective cover 2 is provided with a glass observation window 211. Specifically, in this embodiment, the glass observation window 211 is disposed on the cover plate 21, which facilitates the operator to observe the testing status of the testing fixture inside the test bench. In other embodiments, the glass observation window 211 can be disposed on any one of the upper side plate 22, lower side plate, left side plate 24, and right side plate 23, depending on the actual situation, and is not limited here.

[0058] It should be noted that the balancer is a commonly used device in manufacturing processes. It contains a coiled spring and a steel cable of a certain length for connecting to external components. During use, the coiled spring balances the connected steel cable. This is a conventional technique in the field, and those skilled in the art will readily understand its working principle upon seeing the balancer's design in this application. Therefore, the balancer will not be described in detail here. It should still be noted that this application does not limit the specific model of the balancer; selection should be based on actual needs.
