Abstract
The utility model provides a toothed stopper ring for vehicle fastening bolts. The integral structure of the toothed stopper ring is of a hollow circular thin plate. Teeth are evenly arranged at the middle of the hollow circular thin plate. A round hold is formed by the tips of the teeth. The middle portion of the tip of each tooth protrudes upwards at an angle of 140 degrees to 150 degrees and at a height of 1.1mm to 1.3mm. Protrusions on the tips of the teeth extend elastically to ensure the toothed stopper ring to disperse stress evenly when the toothed stopper ring is stressed. In this way, the looseness of the fastening bolts is prevented. Compared with conventional paper stopper rings, the toothed stopper ring has the advantages that the strength binding force of the toothed stopper ring for the vehicle fastening bolts is increased by 25-30%. The percentage of looseness prevention is reduced by 15-20%. Meanwhile, the effectiveness and the safety are greatly improved.
Description
Technical field
The utility model belongs to field of machining, specifically a kind of profile of tooth stopper ring for the fastening automobile bolt.
Background technique
The profile of tooth stopper ring cooperates through bolt and is connected with automotive body, can prevent that bolt looseness is to reach the purpose of clamping bolt.Traditional profile of tooth stopper ring is by papery stopper ring and bolted, and the crown of papery stopper ring is level, and fastening force is relatively poor, comes off easily.
The model utility content
The utility model provides a kind of profile of tooth stopper ring for the fastening automobile bolt, and it is relatively poor to have overcome traditional stopper ring fastening force, holds caducous shortcoming.
Profile of tooth stopper ring overall structure for the fastening automobile bolt described in the utility model is a stainless steel open circles thin plate, the middle part is uniform-distribution with tooth, and the crown end forms circular port, and the crown middle part raises up, angle is 140 °～150 °, highly is 1.1mm～1.3mm.
The beneficial effects of the utility model are: the projection of crown has kept elastic stretch, can Uniform Dispersion stress when guaranteeing that the profile of tooth stopper ring is stressed, play the effect that prevents that clamping bolt is loosening.Compare with original usefulness papery stopper ring, this techniques intensity fastening force has improved 25-30%, prevents the ratio of the becoming flexible 15-20% that descended, and validity and Security improve greatly.

Fig. 3 is for making the used press tool schematic representation of stopper ring.
Embodiment
Fig. 1 is the utility model plan view, and the profile of tooth stopper ring overall structure for the fastening automobile bolt described in the utility model is the open circles thin plate that stainless steel is made, and the middle part is uniform-distribution with tooth, and the crown end forms circular port.
Fig. 2 is side view of the present utility model.The crown middle part raises up, and angle is 140 °～150 °, highly is 1.1mm～1.3mm.
Working principle of the present utility model is: when clamping bolt and profile of tooth stopper ring are fastenedly connected when the vehicle body effect is stressed, the profile of tooth stopper ring plays a bullet top and eliminates the effect of tension force, simultaneously clamping bolt there is the effect of individual pretightening force, after guaranteeing both secure fit, clamping bolt can not become flexible, and then has played the effect of effective use.
The projection of crown has kept elastic stretch, can Uniform Dispersion stress when guaranteeing that the profile of tooth stopper ring is stressed, and play clamping bolt and prevent the effect of becoming flexible.Cooperate the clamping bolt technology to compare with original usefulness papery packing ring, this techniques intensity fastening force has improved 25-30%, prevents the ratio of the becoming flexible 15-20% that descended, and validity and Security improve greatly.
Fig. 3 is for making the used press tool schematic representation of stopper ring.
Height of punch: 10mm ± 0.1mm;
Punch diameter: 2.55mm ± 0.05mm;
R angle: R10mm ± 0.1mm in the moulding.
The concrete application approach of the utility model is a lot; the above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
