A cross-sectional profile of one convex portion is in an L shape, and a cross-sectional profile of the other convex portion is in a V shape.

[0049] The working principle of the functional headrest skeleton assembly inspection tool of the present utility model is as follows:

[0050] See Figure 1 , the functional headrest skeleton assembly has two vertical tubes 91 (in a vertical state when installed on an automobile seat). The top ends of the two vertical tubes 91 are connected by a cross tube 92. A connecting plate 93 is fixedly connected to the rear sides of the two vertical tubes 91. The cross tube 92 is connected with a swing plate 94, and the swing angle of the swing plate 94 is adjustable.

[0051] The process of installing the functional headrest skeleton assembly onto the inspection tool is as follows:

[0052] First, place the swing plate 94 on the reference pad 1, so that the bottom wall of the swing plate 94 is close to the reference plane of the top wall of the reference pad 1, and insert the positioning pin 11 of the reference pad 1 into the positioning hole 941 provided on the swing plate 94, and place the two vertical pipes 91 on the pipe section placement blocks 21 and the pipe end placement blocks 22 on both sides, so that the ends of the vertical pipes 91 are close to the ends of the placement grooves of the pipe end placement blocks 22 (such as Figure 6 shown).

[0053] Then, the rear swing arm 34 is swung forward, thereby driving the rear pressure arm 32 to swing forward through the connecting rod 33 until the positioning pressure block 321 presses the hinge seat 942 of the swing plate 94 downward, so that the bottom wall of the connecting plate 93 is closely attached to the top wall reference plane of the reference pad 1 (such as Figure 6 As shown in FIG. 1 ), the functional headrest frame assembly is positioned. At this time, the rear swing arm 34 and the connecting rod 33 are in a collinear state and are both in a vertical state (as shown in FIG. Figure 8 The rear pressure arm 32 is vertically upwards under the reaction force of the swing plate 94, and is in line with the rear swing arm 34 and the connecting rod 33. Therefore, the rear pressure arm 32 is in a self-locking state, so that the bottom wall of the connecting plate 93 remains close to the top wall reference plane of the reference pad 1.

[0054] Then, push each anti-slip strip 52 inward in turn, and use the detection notch 521 as a reference to detect the four planes on both sides of the top wall of the connecting plate 93: if the right angle of the detection notch 521 is just stuck in the edge of the plane, the height of the plane meets the requirements; if the right angle of the detection notch 521 cannot be stuck in the edge of the plane, or exceeds the edge of the plane, the height of the plane does not meet the requirements.

[0055] After completing the inspection of the four planes, drag out each anti-slip strip 52, then swing the front swing arm 42 backward, so that the rod mounting seat 43 swings to above the top wall of the connecting plate 93, and then, insert the positioning pin rod 402 into the positioning pin hole 401 provided on the front swing arm 42 and the positioning pin hole 401 provided on the front hinge seat 41, so that the rod mounting seat 43 is in a horizontal position, thereby making each hole measuring rod 44 in a vertical position, and then, push each hole measuring rod 44 downward in turn, and detect it by cooperating with the lower end of the hole measuring rod 44 with the hole provided on the connecting plate 93.

[0056] The pin seat 61 is provided with a pin hole for the detection pin 62 to pass through. The detection pin 62 penetrates into the rear end of the vertical pipe 91 to detect the rear end.

[0057] The outer slot detection block 73 is used to detect the outer slot spacing of the vertical pipe 91. The inner slot detection block 83 is used to detect the inner slot of the vertical pipe 91.

[0058] The inspection fixture of the utility model can detect multiple items at one time, such as the distance between the two vertical tubes 91 of the functional headrest frame assembly, the hole diameter at the end of the vertical tube 91, the position and size of the holes provided in the connecting plate 93, the position accuracy of four planes on both sides of the top wall of the connecting plate 93, etc., thereby greatly improving the inspection efficiency and inspection accuracy of the functional headrest frame assembly.

[0059] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
