Preferably, the bottom of the clamping groove extends downwards to form a positioning portion, and a positioning bolt hole for locking is formed in the middle of the positioning portion.

Preferably, a plurality of lightening holes for reducing weight are arranged upwards on the bottom of the clamping groove.

Preferably, the bottom of the clamping groove is provided with more than two arc-shaped strip grooves, and the nylon sheet is provided with strip protrusions which are clamped with the strip grooves in a matching manner.

Preferably, a platform body is arranged at the position, outside the circumference of the through hole, on the upper end of the arc-shaped concave surface.

Preferably, the lower end face of the nylon sheet is a rough face.

The technical scheme has the following beneficial effects:

1. set up a bead in this scheme, and the up end of bead is the arc convex surface, can realize better stress stability, and the body up end is located the width direction's of bead both sides undercut respectively and forms the arc concave surface in addition, also is the stability in order to improve the atress equally, especially after locking, can realize stable purpose better. The setting of groove and nylon piece is put to the card, can be so that the nylon piece provides certain shock attenuation purpose, the effective absorption impact force, moreover the lower extreme of nylon piece stretches out terminal surface under the body, and extension length is less than 1mm and is greater than 0.2mm, can be so that absorbing effect is better.

2. The positioning part and the positioning bolt hole are arranged, so that the positioning effect is better;

3. the weight of the body can be effectively reduced due to the arrangement of the plurality of lightening holes, and in order to improve the strength, the holes adopted by the lightening holes from inside to outside are different in form, and the lightening holes respectively adopt a round hole, more than two flat holes and a larger hole, so that the bearing capacity of the body can be effectively improved.

4. The arrangement of the strip-shaped groove and the strip-shaped protrusion can greatly improve the clamping effect of the nylon sheet and the clamping groove, and particularly, the clamping can be realized in an interference fit mode, so that better locking can be realized.

5. The arrangement of the table body can enable the bolt to form a bearing surface during locking, and effectively improves the locking effect.

6. The setting of rough surface can effectively promote frictional force to make the shock attenuation effect promote, cooperation stability promotes.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 6, this embodiment provides a plate spring briquetting accessory for vehicle, including body 1, the middle part department of the width direction of body 1 up end upwards protrudes and forms bead 2, the up end of bead 2 becomes arc convex surface 21, the both sides that body 1 up end is located the width direction of bead 2 are undercut respectively and form arc concave surface 3, it is equipped with wear-to-establish hole 4 that runs through from top to bottom to lie in arc concave surface 3 department on body 1, the circumference outside department that lies in wear-to-establish hole 4 on the arc concave surface 3 is equipped with stage body 5. The middle part department of the width direction of terminal surface upwards caves in and forms clamping groove 11 under body 1, clamping groove 11 penetrates out 1 length direction's of body both ends, the clamping has nylon sheet 6 in the clamping groove 11, the lower extreme of nylon sheet 6 stretches out terminal surface under the body 1, and extension length is less than 1mm and is greater than 0.2mm, and preferred in this scheme is 0.5 mm. The lower end face of the nylon sheet 6 is a rough face, and the rough face can be in conventional structures such as stripes and grids. More than two arc-shaped strip grooves 12 are arranged at the bottom of the clamping groove 11, and strip protrusions 61 matched with the strip grooves 12 and clamped are arranged on the nylon sheet 6.
