[0016] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0018] In the description of the embodiments of the present utility model, it should be noted that if the terms "upper", "lower", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the utility model product is usually placed when in use. It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, if the terms "first", "second", etc. appear in the description of the present utility model, they are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0019] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] As shown in the accompanying drawings, the utility model comprises a base plate 1 and a pair of cover plate imitation fixing seats 2 symmetrically mounted on the base plate 1. During testing, the left and right reinforced cover plates of the rear door of the vehicle are placed on the corresponding cover plate imitation fixing seats 2 respectively.

[0021] Both ends of the cover plate imitation fixing seat 2 are respectively provided with positioning columns 3 corresponding to the cover plate mounting holes, and a quick clamp 4 is provided on the base plate 1 located on one side of the positioning columns 3. The top surface of the cover plate imitation fixing seat 2 is provided with a circle of detection grooves 5 corresponding to the outer periphery of the cover plate, and a group of detection pens 6 used in conjunction with the detection grooves 5 are provided on the base plate 1.

[0022] The positioning column 3 is used to position the mounting holes at both ends of the cover plate. After positioning, it is tightened by the quick clamp 4. Each cover plate is fixed by two quick clamps 4. During inspection, the cover plate is compared with the inspection groove 5 to see if there are major defects, and then the inspection pen 6 is moved in the inspection groove 5. If there are burrs or uneven areas on the edge of the cover plate, the inspection pen 6 will feel a sense of frustration during the movement, so as to determine whether the cover plate is qualified.

[0023] Furthermore, the cover plate profile fixing seat 2 is inclined with one end higher than the other end, which is conducive to quickly cleaning dust and debris on its surface.

[0024] Preferably, the positioning column 3 is a cylindrical column, and a group of cutouts are provided on the side wall of the cylindrical column, and a tightening rod 8 which can move up and down in the cylindrical column is provided on the cover plate imitation fixing seat 2, and the diameter of the tightening rod 8 is the same as the inner diameter of the cylindrical column.

[0025] That is, the positioning column 3 is an expansion sleeve structure with a certain degree of elasticity. When the tensioning rod 8 is retracted to the bottom of the positioning column 3, the positioning column 3 can shrink inward when subjected to external force, and the mounting hole of the cover plate can be smoothly inserted into or pulled out of the positioning column 3. When the tensioning rod 8 is extended into the positioning column 3, the positioning column 3 is kept in a vertical state, and the mounting hole of the cover plate can fit closely with the positioning column 3 to maintain its positioning accuracy.

[0026] One end of the top of the cylindrical column is provided with a chamfer, so that the mounting hole of the cover plate can be smoothly inserted into the positioning column 3 when the cover plate is installed.

[0027] Furthermore, both ends of the cover plate imitation fixing seat 2 are provided with pressure plates 9 for controlling the up and down movement of the tensioning rod 8. The cover plate imitation fixing seat 2 is provided with a pressure plate mounting hole. The pressure plate 9 can be rotatably installed in the pressure plate mounting hole through a pin shaft. One end of the pressure plate 9 extends out of the pressure plate mounting hole, and the tensioning rod 8 is movably connected to the pressure plate 9 located at one end of the pressure plate mounting hole.

[0028] A tensioning spring 10 is provided below one end of the bottom of the tensioning rod 8 .

[0029] In the default state, the tensioning rod 8 is tensioned upward in the positioning column 3 by the tensioning spring 10. When the cover is installed or removed, one end of the pressure plate 9 is pushed upward, and the tensioning rod 8 is moved out from the positioning column 3. The positioning column 3 has a certain elasticity, and the cover can be smoothly installed or removed from the positioning column 3. Conversely, the pressure plate 9 is released or pressed downward to move the tensioning rod 8 into the positioning column 3. At this time, the positioning column 3 remains tensioned, and the cover can be effectively fixed.

[0030] Furthermore, a group of detection pen mounting seats 11 are provided on the base plate 1, and the detection pen 6 is movably plugged into the mounting seats 11 for quick removal and placement. A spring wire can be connected between the detection pen 6 and the mounting seats 11 to prevent the detection pen 6 from falling and being lost.
