Detailed description of the invention
Below in conjunction with accompanying drawing and concrete embodiment, the utility model will be further described.
Fig. 1 and Fig. 2 is respectively the structural representation of cross-track tyre chain tightener described in the utility model and does not comprise the structural representation of cross-track tyre chain tightener of prevention cover and back-moving spring.Cross-track tyre chain tightener of the present utility model is connected with the anti-slipping chain of tire, is generally arranged on the joint location of anti-slipping chain, thus anti-slipping chain head and the tail can be coupled together.As depicted in figs. 1 and 2, described cross-track tyre chain tightener comprises base 1, tooth bar 2, lock dog 3 and prevention cover 4, and wherein, described lock dog 3 is connected with described base 1 by the first axle 3-1, and described lock dog 3 rotates around described first axle 3-1; Be formed with space in the middle of described lock dog 3 and described base 1, the head end of described tooth bar 2 inserts in space, and can move in space, and described lock dog 3 can block the tooth of described tooth bar 2, ensures that described tooth bar 2 can not move easily; Described prevention cover 4 to be connected with described base 1 by the second axle 4-1 and to be positioned at the top of described lock dog 3, described prevention cover 4 can be rotated around described second axle 4-1, when described prevention cover about 4 is rotated time, described prevention cover 4 can be withstood the tooth of described tooth bar 2 thus to described tooth bar 2 one power, described tooth bar 2 be moved right (as shown in Figure 1).
When described cross-track tyre chain tightener work, described prevention cover 4 is upwards rotated, the end of described prevention cover gives the power on the teeth directional right side of described tooth bar 2, thus described tooth bar 2 is moved right, described tooth bar 2 is dragged in the space of described lock dog 3 and described base 1 centre, as shown in Figure 2, the tapered end of described lock dog 3 and the tooth of right end and described tooth bar 2 fasten, when described tooth bar 2 moves right, the tapered end of described lock dog 3 and the tooth of described tooth bar 2 do not have resistance, thus can tighten up anti-slipping chain; When described tooth bar 2 is to left movement, the tapered end of described lock dog 3 can give the certain resistance of tooth of described tooth bar 2, and described tooth bar 2 can not be moved to the left; Need described cross-track tyre chain tightener detachable, press the left end of lock dog 3, the clamped position of the tooth of the tapered end of lock dog 3 and described tooth bar 2 is separated, thus pull out described tooth bar 2.
In cross-track tyre chain tightener described in the utility model, comprise back-moving spring 5 further, described back-moving spring 5 is connected with described base 1 by the 3rd axle 5-1.As shown in Figure 1, described cross-track tyre chain tightener comprises described back-moving spring 5 further and rotates around described 3rd axle 5-1.
In cross-track tyre chain tightener described in the utility model, the end of described tooth bar 2 is provided with hook 2-1, and described back-moving spring 5 can be stuck on described hook 2-1.As shown in Figure 1, the end of described tooth bar 2 and left end are provided with hook 2-1, described back-moving spring 5 can be stuck on described hook 2-1, for in vehicle traveling process, anti-slipping chain is if any loosening, and described back-moving spring 5 can shrink automatically, thus described tooth bar 2 is moved right, thus can anti-slipping chain be tightened up, make anti-slipping chain can be close to tire all the time, ensure that the safety of running car.
In cross-track tyre chain tightener described in the utility model, described prevention cover 4 both sides are provided with groove 4-2, for described back-moving spring 5 is embedded.As shown in Figure 1, described groove 4-2 is located at the both sides of described prevention cover 4, described back-moving spring 5 embeds described groove 4-2, make described back-moving spring 5 not yielding thus described base 1 can not be departed from, well ensure that stationarity and the stability of described back-moving spring 5, thus further ensure described anti-slipping chain tightener tighten up effect, make ride safety of automobile.
In cross-track tyre chain tightener described in the utility model, the material of described base 1 is metal, can be aluminium, also can be iron, also can be steel.Aluminium is argenteous light metal, has good ductility, can form the fire coat that one deck prevents metal corrosion in damp air.Iron is glossiness silvery white metal, and firmly have ductility, fusing point is 1535 DEG C, boiling point 2750 DEG C, has very strong ferrimagnetism, and has good plasticity and permeability of heat.Steel take iron as essential element, and the metallic material of carbon content generally also containing other elements below 2.0%, steel has better physics, chemistry, mechanical characteristics than the initial pig iron.Metab has good hardness, thus is unfavorable for damaging, and improves safety.
