[0025] See Figure 1This is a specific embodiment of the clamping structure of the present utility model. The clamping structure includes a housing 1 and a swing arm 2. The housing 1 includes a housing body 11 and a first connecting member 12 provided on the housing body 11; the swing arm 2 includes a swing arm body 21 and a second connecting member 22 provided on the swing arm body 21; the first connecting member 12 and the second connecting member 22 are used to connect the housing 1 and the swing arm 2. The first connecting member 12 includes a first cavity 121, and a clamping groove 122 is provided on the outer periphery of the first cavity 121. The second connecting member 22 includes a second cavity 221, and a clamping buckle 222 is provided on the inner periphery of the second cavity 221; the clamping buckle 222 is snapped into the clamping groove 122 by interference fit to form a clamping structure.

[0026] Further, the first cavity 121 of the first connecting member 12 is cylindrical, and a clamping groove 122 is circumferentially provided along the outer wall circumference of the first cavity 121. The clamping groove 122 is a through groove. The second cavity 221 of the second connecting member 22 is cylindrical, and a circular clamping buckle 222 is circumferentially provided along the inner wall circumference of the second cavity 221. The clamping groove 122 and the clamping buckle 222 can be matched to form a circular clamping buckle structure.

[0027] Further, the housing body 11 and the first connecting member 12 are arranged perpendicular to each other. The second connecting member 22 is located at one end of the swing arm body 21 and is perpendicular to the swing arm body 21. The second connecting member 22 further includes a shaft structure 223, and the shaft structure 223 is cylindrical and is formed in the second cavity 221. The shaft structure 223 extends axially outward and extends out of the second cavity 221. The diameter of the shaft structure 223 is smaller than the diameters of the first cavity 122 and the second cavity 221. When the clamping buckle 222 and the clamping groove 122 form a clamping structure, the first cavity 121 is used to accommodate the shaft structure 223.

[0028] Further, a handle member 23 is provided at the other end of the swing arm body 21, and the handle member 23 is used to control the free rotation of the swing arm.

[0029] See Figure 2 As shown, after the clamping buckle 222 and the clamping groove 122 form a clamping structure, there is a gap between the shaft structure 223 and the first cavity 121. After the clamping buckle 222 and the clamping groove 122 form a clamping structure, the swing arm 2 rotates 360 degrees around the housing 1 with the shaft structure 223 as the axis.

[0030] Refer to Figure 3This is a schematic diagram of the installation principle of the circular clamping structure of the present utility model. Apply a certain force to snap the circular buckle 222 of the swing arm 2 into the circular slot 122 of the housing 11. During the snapping process, the circular buckle 222 of the swing arm 2, due to its thin wall and easy deformation, is first deformed and opened outward by the axial supporting force of the housing 11, and then returns to its original size and shape after being snapped into the slot 122, forming an interference fit clamping form with reverse buckle, thereby preventing the swing arm 2 from loosening from the housing 11. After being snapped in, the swing arm 2 can freely rotate around the housing 1 through the shaft structure 223. Through this interference fit clamping structure, it is not easy to loosen after being assembled in place. At the same time, a suitable gap is reserved for the matching part between the shaft structure 223 and the first cavity 121 to enable the swing arm 2 to freely rotate around the housing 1 without jamming. In order to prevent noise generated during the rotation of the swing arm, an appropriate amount of grease is applied at the clamping joint and the bottom where the swing arm matches the housing.

[0031] Further, a third cavity 13 is provided at the upper end of the housing 11. The third cavity 13 is used to accommodate a non-contact PCB board, and the housing 1 can also be connected to a connecting member. Thus, the circular clamping structure of the present utility model can be applied to a vehicle height sensor.

[0032] At the same time, this structure can also be widely applied to other similar rotating structures, and the present application does not limit this here.

[0033] It should be noted that the embodiments of the present disclosure have good implementability and do not impose any form of limitation on the present disclosure. Any person skilled in the art may use the disclosed technical content to modify or transform it into equivalent effective embodiments. However, as long as it does not depart from the technical solution of the present disclosure, any modification, equivalent change or modification made to the above embodiments based on the technical essence of the present disclosure still falls within the scope of the technical solution of the present disclosure.
