DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The present utility model will be specifically described below with reference to the accompanying drawings. As shown in the Figure 1 drawing, a snow pressure resistance tester includes a top plate 1. The lower four corners of the top plate 1 are respectively fixedly connected with support legs 2, and the lower ends of the support legs 2 are respectively fixedly connected with a fixed plate 3. Among them, bolt holes are respectively formed in the peripheral parts of the interior of the fixed plate 3; a control panel 4 is fixedly connected to the lower side of the outer wall of any one of the support legs 2.

[0015] One of the snow pressure resistance testers further includes a profiling pressure application component 5, and the profiling pressure application component 5 is fixedly connected to the top plate 1; the profiling pressure application component 5 is electrically connected to the control panel 4, which is beneficial to achieving the effect of profiling pressure application, so that the snow pressure resistance tester can be applicable to various models of vehicles without replacing the tested components, thereby effectively improving the test efficiency and making it more convenient to use.

[0016] In this embodiment, in combination with the Figure 2 drawing and the Figure 3As shown, the imitation form pressing assembly 5 includes a water bag 51. Around the upper end of the water bag 51, inverted U-shaped fixing strips 52 are respectively sewn. And an annular bracket 53 is arranged inside between the inverted U-shaped fixing strips 52. Among them, at the peripheral parts on the upper side of the annular bracket 53, first rope loops 54 are respectively fixedly connected; a second rope loop 55 is arranged on the upper side of the water bag 51; one ends of connecting ropes 56 are respectively tied inside the first rope loops 54, and the other ends of the connecting ropes 56 are respectively tied inside the second rope loop 55; a weighing sensor 57 is fixedly connected to the upper end of the second rope loop 55, and an electric push rod 58 is arranged on the upper side of the weighing sensor 57. Among them, the lower end of the output rod of the electric push rod 58 is fixedly connected to the upper end of the weighing sensor 57.

[0017] In this implementation scheme, specifically, the electric push rod 58 is fixedly connected to the middle part of the upper part of the top plate 1, and the lower end of the output rod of the electric push rod 58 penetrates through the middle part of the inside of the top plate 1.

[0018] In this implementation scheme, specifically, a rotation prevention assembly is fixedly connected to the lower right side of the water bag 51.

[0019] In this implementation scheme, in combination with the attached Figure 4 As shown, the rotation prevention assembly includes a fixing ring 6. The fixing ring 6 is fixedly connected to the lower right side of the water bag 51, and a traction rope 7 is tied inside the fixing ring 6. An operator can apply a traction force to the water bag 51 through the traction rope 7 and the fixing ring 6, thereby avoiding the problem of rotation when the water bag 51 descends.

[0020] In this implementation scheme, specifically, the water bag 51 is a rubber water bag with a circular upper end and a rectangular lower end.

[0021] In this implementation scheme, specifically, the inverted U-shaped fixing strips 52 are inverted U-shaped rubber strips.

[0022] In this implementation scheme, specifically, the fixing ring 6 is a rubber ring.

[0023] In this implementation scheme, specifically, the control panel 4 is a digital display panel embedded with an FX2N-48 type PLC.

[0024] In this implementation scheme, specifically, the weighing sensor 57 and the electric push rod 58 are respectively electrically connected to the control panel 4.

[0025] In this implementation scheme, when conducting a snow pressure resistance test on an automobile, first, clear water is injected into the water bag 51 from its upper end. Subsequently, the control panel 4 will detect the total weight of the components below the load cell 57 through the load cell 57 and display it. Then, the automobile is placed on the lower side of the water bag 51, and the electric push rod 58 is controlled to start through the control panel 4, so that the output rod of the electric push rod 58 extends. At this time, the water bag 51 will move downward until the bottom of the water bag 51 contacts the top of the automobile. Since the water bag 51 is a rubber water bag, the bottom of the water bag 51 will deform according to the shape of the top of the automobile, thereby achieving the purpose of profiling pressure application. When the water bag 51 contacts the top of the automobile, the weight displayed on the control panel 4 will decrease. It should be noted here that the total weight of the components below the load cell 57 minus the weight displayed on the control panel 4 is the weight borne by the top of the automobile. Thus, through the control panel 4 and the load cell 57, it is convenient for the operator to control the gravity applied to the top of the automobile and achieve the effect of profiling pressure application. Therefore, the snow pressure resistance tester can be applicable to various vehicle models without replacing the detected components, thereby effectively improving the test efficiency and being more convenient to use.

[0026] Using the technical solution described in the present utility model, or a person skilled in the art being inspired by the technical solution of the present utility model to design a similar technical solution and achieving the above technical effects shall fall within the protection scope of the present utility model.
