Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the utility model provides a new energy automobile is plastics buckle for automobile body, including the

joint body

1, 1 top of the joint body is provided with

inserts chamfer

2, 1 inside fretwork passageway 3 that is provided with of the joint body, just the joint body 1 has four sides, just open jack catch 4 is all installed to 1 every side of the joint body.

In specific practical use, the clamping body 1 is fixed on a ground disc wrapping piece, a buckling groove is formed in the ground disc, and the clamping body 1 is embedded in the buckling groove and tightly occluded in the buckling groove to enable the wrapping piece to be tightly attached to an automobile chassis; and the position that corresponds fretwork passageway 3 on car parcel piece is provided with the through-hole, and the operating personnel of being convenient for can get into the fretwork passageway 3 in the joint body 1 from the outside and operate after parcel piece installation is good.

Smooth tip is formed when reducing the volume of the top end of the clamping body 1 through inserting the chamfer 2, and the clamping body 1 is favorably inserted into a catching groove on an automobile chassis.

As shown in fig. 2, the open type claw 4 includes a movable channel 401 disposed at a side of the clamping body 1 and a floating claw body 402 disposed at an outer side of the movable channel 401, a top end of the floating claw body 402 is connected with an inner portion of the movable channel 401 through an inclined elastic branch 403, and a bottom end of the floating claw body 402 is connected with an inner portion of the movable channel 401 through a Z-shaped elastic branch 404.

The jack catch on the original joint body 1 is the enclosed construction with joint body 1 integrated into one piece, when joint body 1 inserted the chassis catching groove, the jack catch can take place the extrusion with the cell wall of chassis catching groove, and jack catch and joint body 1 zonulae occludens lead to joint body 1 to obstruct the inboard shrink of jack catch.

An adjusting gap 405 is formed between the floating claw body 402 and the movable channel 401, and an included angle formed by the inclined elastic supporting strip 403 and the clamping body 1 is an acute angle.

The advantages of this example are:

(1) through setting up fretwork passageway 3 with the internal portion of joint 1 hollows out to reduce the weight of the joint body 1, and make the elastic deformation ability of the joint body 1 than original solid joint body stronger, and through the installation dismantlement subassembly in fretwork passageway 3, can easily take off the joint body 1 from the vehicle chassis catching groove when the car parcel spare needs maintenance or change.

(2) Remove to change original closed claw body through open claw body 4, traditional closed claw body can produce great hindrance when the joint body 1 inserts, and open claw body 4 has strengthened the ability that prevents joint body 1 and deviate from the catching groove when having reduced and inserted the hindrance.

The outside of the hollow channel 3 is communicated through the movable channel 401, and Z-shaped elastic supporting strips 404 and inclined elastic supporting strips 403 are arranged at two ends of the floating claw body 402; connect Z shape elasticity branch 404 and slope elasticity branch 403 right-hand member in movable channel 401, erect the floating claw body 402 through both, when floating claw body 402 receives the extrusion in the inboard, through the elasticity of Z shape elasticity branch 404 and slope elasticity branch 403, can make floating claw body 402 remove to adjusting clearance 405 to reduce floating claw body 402 at the surperficial bulge degree of joint body 1, reduce the joint body and insert the degree of difficulty.

The adjustment gap 405 is a reserved space formed between the movable duct 401 and the floating pawl body 402, and the floating pawl body 402 can be retracted inward through the reserved space.

Because the area of the movable channel 401 is larger than that of the floating claw body 402, the purpose of this is that the part of the floating claw body 402 can be accommodated in the movable channel 401, so the bottom of the floating claw body 402 needs the Z-shaped elastic branch 404 to be connected with the movable channel 401 in a special shape, and by utilizing the unique acute angle of the middle part of the Z-shaped elastic branch 404 and the inclined elastic branch 403 which are downward outside, when the clamping body 1 is inserted, the resistance generated by the Z-shaped elastic branch 404 and the inclined elastic branch 403 is smaller, and when the clamping body 1 has a tendency of being pulled out from the chassis catching groove, the Z-shaped elastic branch 404 and the inclined elastic branch 403 can rotate to both sides after being stressed, so that the generated resistance is larger.

As shown in fig. 3, a detaching assembly is arranged in the hollow channel 3, the detaching assembly includes four plastic strips 5, the plastic strips 5 are in one-to-one correspondence with the inner sides of the floating claws 402 and are hinged to each other, the other ends of the plastic strips 5 penetrate through the movable channel 401 and extend into the hollow channel 3, and the other ends of the four plastic strips 5 are connected through a detaching pull ring 6.

Through set up the through-hole the same with fretwork passageway 3 on car parcel piece, can dismantle pulling of pull ring 6 through instruments such as finger or drag hook in the external world, when dismantling pulling of pull ring 6, the pulling plastic strip 5 downstream makes and receives the power of syncline inboard with the unsteady claw body 402 of plastic strip 5, makes unsteady claw body 402 contract, is convenient for dismantle joint body 1 from the catching groove.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
