[0003] This type of automobile body and chassis connecting bolts has the following disadvantages:

[0004] The position needs to be selected according to the actual situation of the chassis. The U-shaped structure is installed through the chassis beam and the subframe as a whole. Especially for models with relatively compact arrangements of existing chassis beam brackets, gas cylinders, lines, drive shafts, suspensions, etc., the middle space is relatively small. The installation space of the existing automobile body and chassis connecting bolts is relatively small, and the position cannot be selected for installation at will. Now a kind of automobile body and chassis connecting bolt is proposed. Utility Model Content

[0005] The main purpose of the utility model is to provide a connecting bolt between a car body and a chassis, so as to solve the problem that the installation space of the connecting bolt between a car body and a chassis is relatively small and the installation position cannot be selected arbitrarily.

[0006] In order to achieve the above-mentioned object, according to one aspect of the utility model, a bolt for connecting a car body and a chassis is provided, comprising a connecting mechanism, a chassis beam and a subframe, wherein the connecting mechanism comprises a stud, and the stud can be adjusted in position between the chassis beam and the subframe;

[0007] The connection mechanism also includes two groups of symmetrical fastening mechanisms, one group of fastening mechanisms is used for fixed connection between one end of the stud and the chassis beam, and the other group of fastening mechanisms is used for fixed connection between the other end of the stud and the subframe;

[0008] A group of the fastening mechanisms includes a bolt pressure plate, which is used to hook the flange of the chassis beam.

[0009] Furthermore, the bolt pressing plate is slidably connected to the surface of the stud, and one end of the bolt pressing plate is configured to be J-shaped.

[0010] Furthermore, the fastening mechanism also includes a group of flat washers, a group of spring washers and two groups of hexagonal nuts, the flat washers and the spring washers are slidably connected to the surface of the studs, and the hexagonal nuts are threadedly connected to the surface of the studs.

[0011] Furthermore, the spring washer is located above the flat washer, and the two hexagonal nuts are located above the spring washer.

[0012] Furthermore, a pull cord is detachably provided on the surface of the sub-frame, and the pull cord is fixedly connected to the surface of the sub-frame via a fastening mechanism.

[0013] Furthermore, the sub-frame and the pull code surface are threadedly connected with a hexagonal bolt, the surface of the hexagonal bolt is slidably connected with a group of flat washers and a group of spring washers, and the surface of the hexagonal bolt is threadedly connected with two groups of hexagonal nuts.

[0014] Furthermore, a fixing block is fixedly mounted on the lower surface of the sub-frame, and the fixing block is movably fitted to the surface of the chassis beam.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] When the internal space is small when the body and chassis are installed, the studs can be set to select a suitable position between the chassis beam and the subframe. The two fastening mechanisms are screwed close to each other on the surface of the studs, so that the connecting bolts between the body and chassis of the car can be quickly positioned and installed, simplifying the installation process and working hours, solving the problem of small installation space, reducing work difficulty and improving production efficiency.
