A protective cover is provided on the test platform. Multiple first connecting plates connected to the protective cover are located on the rotating shaft. A proximity switch is located below the front end of the protective cover. An arcuate groove penetrating into the circular tube is located on the upper front end surface of each circular tube, and a limiting bolt connected to the rotating shaft is located on the arcuate groove.

[0007] Furthermore, the rotating shaft is a hollow tube.

[0008] Furthermore, the protective cover has a semi-circular structure.

[0009] Furthermore, a second connecting plate is provided on the support plate below the circular tube, and a circular bar is provided on the second connecting plate.

[0010] Furthermore, the protective cover is provided with a handle at the front.

[0011] Furthermore, the protective cover is provided with a transparent window.

[0012] The beneficial effects of this utility model are:

[0013] By adopting the above technical solution, the use of a first support platform and a second support platform raises the operating position, facilitating operator operation. A rotating shaft at the rear of the protective cover allows the cover to be rotated, precisely covering the working part of the test bench. The cooperation of the arc groove and the limit bolt allows the protective cover to rotate within a specified range. A proximity switch is located below the front of the protective cover to prevent the machine from starting and causing injury to the operator if the protective cover is not in place, thereby improving safety performance.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Reference Figures 1 to 5This utility model provides a coupling torque testing bench, including a frame 3, a test bench 5 on the frame, a first support platform 1 at the lower left end of the frame 3, a second support platform 2 at the lower right end of the frame 3, a plurality of support plates 9 at the rear of the frame 3, a circular tube 10 on the same axis at the upper end of each support plate 9, the plurality of circular tubes 10 being connected by a rotating shaft 11 passing through the plurality of circular tubes 10, a protective cover 6 on the test bench 3, a plurality of first connecting plates 16 connected to the protective cover 6 on the rotating shaft 11, a proximity switch 4 at the lower front end of the protective cover 6, an arc groove 14 penetrating into the circular tube 10 on the upper front end surface of the circular tube 10, and a limiting bolt 15 connected to the rotating shaft 11 on the arc groove 14.

[0023] This technical solution employs a first support platform 1 and a second support platform 2, which raises the operating position for easier operator operation. A rotating shaft 11 is provided at the rear end of the protective cover 6, allowing the protective cover 6 to rotate and precisely cover the working part 3 of the test bench. The cooperation between the arc groove 14 and the limit bolt 15 allows the protective cover 6 to rotate within a specified range. A proximity switch 4 is provided below the front end of the protective cover 6, which can prevent the machine from starting and causing injury to the operator if the protective cover 6 is not in position, thereby improving safety performance.

[0024] During operation, the equipment will only start working normally after the proximity switch 4 detects that the protective cover 6 is in place. The test bench 3 can be used for multiple purposes, such as coupling limit rotation testing and precise measurement of coupling torque values; this is existing technology and will not be described in detail here. The housing 8 on the left side of the test bench is used for control testing; this is existing technology and will not be described in detail here.

[0025] For example, in some embodiments, the rotating shaft 11 is a hollow tube. Of course, a solid tube can also be used instead.

[0026] For example, in some embodiments, the protective cover 6 has a semi-circular structure. The specific shape of the protective cover 6 can be adjusted according to the usage requirements.

[0027] For example, in some embodiments, a second connecting plate 12 is provided on the support plate 6 below the circular tube 10, and a circular rod 13 is provided on the second connecting plate 12. The circular rod 13 is a steel rod. When the protective cover 6 is lowered, the circular rod contacts the first connecting plate 9, so that the circular rod 9 achieves the limiting and supporting functions.

[0028] For example, in some embodiments, the protective cover 6 is provided with a handle 7 at the front. This facilitates the opening and lowering of the protective cover 6.

[0029] For example, in some embodiments, the protective cover 6 is provided with a transparent window. This facilitates observation of the operation of the test bench 3.

[0030] In summary, this utility model, by employing a first support platform and a second support platform, elevates the operating position, facilitating operator operation. A rotating shaft at the rear of the protective cover allows for rotation, precisely covering the working portion of the test bench. The combination of an arc groove and a limiting bolt allows the protective cover to rotate within a specified range. A proximity switch is located below the front of the protective cover to prevent injury to the operator if the machine starts when the protective cover is not in position, thus improving safety performance.

[0031] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
