[0021] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

[0022] like Figures 1 to 5 As shown, a detection fixture for a car seat headrest frame 1 includes a base plate 2 and a detection component. The base plate 2 is provided with multiple groups of detection components, and the detection component includes a length limit block 3, an angle detection block 7 and a slot detection mechanism. Length limit blocks 3 are respectively provided at both ends of the base plate 2, and a groove matching the frame 1 is provided on the length limit block 3. The frame 1 includes a slot and a corner 12. The base plate 2 is provided with a slot detection mechanism corresponding to the slot, and an angle detection block 7 is provided corresponding to the corner 12. The angle detection block 7 is provided with an oblique groove 72 matching the corner 12. If the corner 12 can be smoothly embedded in the angle detection block 7, it means that the angle of the corner 12 is qualified, otherwise it is unqualified. The angle detection block 7 and the length limit block 3 are both provided with a rounded corner 71 matching the frame 1. The rounded corner 71 can not only prevent the frame 1 from being scratched during the assembly process of the frame 1, but also facilitate the assembly of the frame 1 into the groove or oblique groove 72.

[0023] Through multiple groups of detection components, multiple skeletons 1 can be detected at the same time, which improves work efficiency. The length limit block 3 and the angle detection block 7 respectively detect the length and angle of the skeleton 1, which is simple and convenient to operate. The slot detection mechanism includes a first slot detection mechanism 4 and a second slot detection mechanism 5. The first slot detection mechanism 4 and the second slot detection mechanism 5 correspond to the first slot 11 and the second slot 13 on the skeleton 1 respectively, and perform a comprehensive detection on the skeleton 1.

[0024] The card slot detection mechanism includes a moving block 55, a rectangular guide rod 53 and a spring 54. The moving block 55 is provided with a tooth 551 matching the card slot on one side close to the skeleton 1, and the bottom plate 2 is provided with a fixed platform 52 corresponding to the rectangular guide rod 53, and the fixed platform 52 is provided with a rectangular hole matching the rectangular guide rod 53. One end of the rectangular guide rod 53 is fixedly connected to the moving block 55, and the other end is provided with a spherical handle. A spring 54 is provided on the circumference of the rectangular guide rod 53, and one end of the spring 54 is in contact with the fixed platform 52, and the other end is in contact with the spherical handle. When an external force is applied to the spherical handle, if the moving plate can be smoothly moved to the top of the skeleton 1, it means that the size of the card slot is qualified, otherwise it is unqualified. When the moving block 55 is pushed out and the external force is stopped, the moving block 55 automatically returns to its original position under the action of the spring 54. The bottom plate 2 is provided with a first shape reference block 41 corresponding to the first card slot detection mechanism 4, and a second shape reference block 51 corresponding to the second card slot detection mechanism 5. The straightness of the middle section of the skeleton 1 can be detected by the first shape reference block 41 and the second shape reference block 51 .

[0025] The bottom plate 2 is provided with a positioning mechanism 6 corresponding to the card slot detection mechanism, and the positioning mechanism 6 includes a fixed tube 61, a positioning pin 62 and a soft rope 63, and the positioning pin 62 can be inserted into the fixed tube 61. The fixed tube 61 is fixedly connected to the bottom plate 2, and the card slot detection mechanism is provided with a positioning hole 521 that matches the positioning pin 62, and one end of the positioning pin 62 is connected to the fixed tube 61 through a soft rope 63. The positioning pin 62 is inserted into the positioning hole 521 to prevent the rectangular guide rod 53 from moving, so as to partially fix the skeleton 1 and prevent errors caused by the loosening of the skeleton 1 during the detection process. When the positioning pin 62 is not used, the positioning pin 62 can be placed in the fixed tube 61, and the soft rope 63 can prevent the positioning pin 62 from falling and being lost.

[0026] The working principle of the specific implementation of the utility model is: the automobile headrest frame 1 is assembled into the groove of the length limit block 3 and the inclined groove 72 of the angle detection block 7 to detect the length and angle. If the automobile headrest frame 1 can be smoothly assembled into the length limit block 3 and the angle detection block 7, it means that the length and angle of the automobile headrest frame 1 meet the standards. Push the spherical push handle to move the moving block 55 to the top of the automobile headrest frame 1. If the latching teeth 551 of the moving block 55 just fit the latching groove, it means that the size of the latching groove is qualified.
