Abstract
The utility model relates to and aims at providing a U-shaped steel plate bolt for a vehicle. The U-shaped steel plate bolt is better in anti-skidding and fastening effects so that stress at two end portions of a U-shaped steel plate bolt body is balanced and safety performance of the vehicle is improved. The U-shaped steel plate bolt comprises the U-shaped steel plate bolt body and two nuts, wherein each nut is connected with one end portion of the U-shaped steel plate bolt body in rotating mode. The U-shaped steel plate bolt for the vehicle is characterized by further comprising two locking washers with sawteeth, and each locking washer is sleeved on one end portion of the U-shaped steel plate bolt body and arranged between a vehicle lifting lug plate and one nut. Preferably, the locking washers with the sawteeth are internal sawtooth locking washers or external sawtooth locking washers. Two axial contact surfaces of each nut are both planes, and the nuts are hexagon nuts.
Description
Technical field
The utility model relates to a kind of threaded fastener, relates in particular to a kind of automobile-used U-shaped steel plate bolt.
Background technique
At present, in general fastening piece, automobile-used U-shaped steel plate bolt is a kind of general component, this U-shaped steel plate bolt is comprised of a U-shaped steel plate bolt body and two nuts usually, each nut is screwed into respectively on the threaded end of U bolt, and this U bolt is used for being installed in the shackle plate on the car body.Yet nut phenomenon loosening and that come off often can occur when sharp pounding and irregular fluctuation, cause vehicle normally to move.In order to address this problem, Anti-slip nut has appearred on the market, i.e. dapple integral type Anti-slip nut of impact forging forming strip, when yet this kind nut is applied on the automobile-used U-shaped steel plate bolt, surface of contact to shackle plate during locking nut can't reach complete closed, thereby in use occur to become flexible, thereby so that the distortion of U-shaped steel plate bolt body unequal power distribution fractures, can cause larger potential safety hazard.
The model utility content
For deficiency of the prior art, the utility model aims to provide a kind of automobile-used U-shaped steel plate bolt of anti-skidding and fastening better effects if, so that U-shaped steel plate bolt body two end part stress equilibrium improves vehicle safety performance.
In order to address the above problem, the utility model provides a kind of automobile-used U-shaped steel plate bolt, comprise U-shaped steel plate bolt body and two nuts, each nut spins with an end of this U-shaped steel plate bolt body, this automobile-used U-shaped steel plate bolt is characterised in that: also comprise two with the lock washer of sawtooth, each lock washer is set on the end of described U-shaped steel plate bolt body and is arranged between vehicle shackle plate and the nut.
Preferably, described lock washer with sawtooth is internal teeth serrated lock washer or external teeth serrated lock washer.
Preferably, described nut two surface of contact vertically are the plane.
Preferably, described nut is hexagon nut.
Be with serrate lock washer by use, these U-shaped steel plate bolt two ends are stressed evenly, and this tooth lock washer has certain elasticity, can strengthen the pre-tightness of nut.When using on the vehicle shackle plate, the nut on this U-shaped steel plate bolt and lock washer be the fastening shackle plate firmly, can not produce deviation in the using process, and be loosening, and the phenomenon such as come off.
Description of drawings
Fig. 1 is the decomposition texture schematic representation of the automobile-used U-shaped steel plate bolt in the utility model;
Fig. 2 is the scheme of installation of the automobile-used U-shaped steel plate bolt in the utility model when being installed on the vehicle shackle plate.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, automobile-used U-shaped steel plate bolt of the present utility model, comprise U-shaped steel plate bolt body 1, two nuts 2 and two lock washers 3 with sawtooth, this U-shaped steel plate bolt has a curved part and two threaded ends, and each nut spins with one of them end of this U-shaped steel plate bolt body 1.Each lock washer 3 is set on one of them end of described U-shaped steel plate bolt body 1, and under the use state, this lock washer 3 is arranged between vehicle shackle plate and the nut 2.Preferably, described lock washer 3 with sawtooth is internal teeth serrated lock washer or external teeth serrated lock washer.This internal teeth serrated lock washer is to form a circle sawtooth at packing ring annulus inner circumference, and external teeth serrated lock washer is to form a circle sawtooth at the packing ring excircle, and its concrete shape is known shape, no longer describes in detail here.According to different situations and environment, adopt two kinds of different lock washers, can make better firmly fastening shackle plate of nut on the U-shaped steel plate bolt and lock washer, improve the use flexibility ratio of this U-shaped steel plate bolt.
More preferably, described nut 2 two surface of contact vertically are the plane, namely the nut upper surface 21 of this nut does not adopt non slip surface, but employing plane, so that the surface of contact to shackle plate can reach complete closed during locking nut, thereby in use can not become flexible, and this nut processing is easier, has reduced cost of production.This nut is preferably hexagon nut.
Fig. 2 is the scheme of installation of the automobile-used U-shaped steel plate bolt in the utility model when being installed on the vehicle shackle plate.During use, pass in two through holes of end from the vehicle shackle plate with U-shaped steel plate bolt body first, be inserted in lock washer 3 in the end that passes and screw with nut, finish installation, these U-shaped steel plate bolt two ends are stressed evenly, and this tooth lock washer has certain elasticity, can strengthen the pre-tightness of nut.When using on the vehicle shackle plate, the nut on this U-shaped steel plate bolt and lock washer be the fastening shackle plate firmly, can not produce deviation in the using process, and be loosening, and the phenomenon such as come off.
