Description

The test fixture of motorcycle direction handle locking anti-theft device

Technical field

The utility model relates to a kind of test fixture of motorcycle field, especially the test fixture of motorcycle direction handle locking anti-theft device.

Background technology

Existing anti-theft device for motorcycle is a lot, and wherein steering handle locking anti-theft device is more common a kind of, and its ultimate principle is by anti-theft device that direction column of motorcycle is locked, can not normally control motorcycle after making the thief steal car.Steering handle locking anti-theft device will carry out the test of maximal destruction power before dispatching from the factory, the test fixture of Shi Yonging is generally all simpler and easy in the past, as commonly used is the clamping part that is welded into test fixture at the two ends of hollow square steel respectively with two little round steel pipe, be connected into a square groove at the middle part of hollow square steel with the weld all around that is involutory of two angle bar.During use, the clamping part at test fixture two ends is clamped two steering handles about motorcycle, dial torque wrench is inserted in the square groove at hollow square steel middle part, and on dial torque wrench, load maximum permissible torque, see whether the locking anti-theft device can be destroyed, whether qualified to check it.Though this test fixture is simple in structure, and is easy to manufacture, its each position is that welding is fixing, and the clamping part location at two ends is more loosening, when test is exerted oneself, skids easily.According to the difference of type, need to make the test fixture of different size, type is more, and manufacturing cost is higher, brings difficulty to management, will ceaselessly change test fixture in the use, makes testing efficiency on the low side.

The utility model content

The purpose of this utility model provides a kind of test fixture of motorcycle direction handle locking anti-theft device, and the test fixture that solves existing motorcycle direction handle locking anti-theft device generally can only be suitable for a kind of type, and it is unreliable to locate, the problem that testing efficiency is low.

For this reason, the test fixture of motorcycle direction handle locking anti-theft device described in the utility model, comprise crossbeam, the middle part of crossbeam is provided with square hole, and two of crossbeam is provided with chute, dog screw is housed in the chute, this dog screw is installed in the chute by clamping seats, and the square column at dog screw middle part is spacing in chute, and a downward draw-in groove is arranged at the clamping seats bottom, top is provided with spacing stove bolt, and an end of this spacing stove bolt stretches in the connecting hole of clamping seats and contacts with dog screw.

Dog screw can drive clamping seats and horizontally slips on crossbeam in the utility model, and clamping seats can rotate in 360 ° of scopes with respect to dog screw.The square column type part at dog screw middle part is spacing in chute, so dog screw can not rotate with respect to crossbeam, clamping seats and dog screw on gyratory directions, then undertaken spacing by spacing stove bolt and releasing spacing.Therefore this test fixture can carry out accommodation to the length and the open angle of stretching out according to motorcycle, make this test fixture can be used for the motorcycle of various models, usable range is wide, join with the draw-in groove on the clamping seats, make this test fixture location more reliable.

The beneficial effects of the utility model are: can be used for the test of steering handle locking anti-theft device on the various model motorcycles, the location is reliable, and test accurately, and is easy to loading and unloading, improved work efficiency, reduced cost.

Embodiment

As shown in Figure 1 and Figure 2, the utility model is made up of crossbeam 1, dog screw 4, clamping seats 5 and spacing stove bolt 6.The middle part of crossbeam 1 is provided with square hole 2, and during test, an end of dial torque wrench inserts in this square hole 2 to transmit moment of torsion.Two of crossbeam 1 is provided with chute 3, and chute is equipped with dog screw 4 for 3 li, and chute 3 is equivalent to the dragging track of dog screw 4, be connected with clamping seats 5 on the dog screw 4, the middle part of dog screw 4 is square column 4a, and this square column 4a is spacing in chute 3, and dog screw 4 is not rotated with respect to crossbeam 1.One downward draw-in groove 5a is arranged at the bottom of clamping seats 5, and the left and right directions of motorcycle is being stuck among this draw-in groove 5a during test.The top of clamping seats 5 is provided with two spacing stove bolts 6, one end of spacing stove bolt 6 stretches into symmetrically among the connecting hole 5b of clamping seats 5 and contacts with dog screw 4, when needs rotate clamping seats 5, the spacing stove bolt 6 of turn, make it to move back outside the connecting hole 5b of clamping seats 5, releasing is spacing to dog screw 4; Otherwise after clamping seats 5 is rotated in place, screw spacing stove bolt 6 inward, the inner end of spacing stove bolt 6 is tightly leaned on dog screw 4, play the effect that prevents that clamping seats 5 from rotating with respect to dog screw 4.

Fig. 3, Fig. 4, Fig. 8 and Fig. 9 illustrate chute 3 outer end openings on the crossbeam 1, and are up-small and down-big ladder hole shape, and the square column 4a at dog screw 4 middle parts is spacing in bigger following hole 3a.The last hole 3b of chute 3 and the step surface between the following hole 3a play position-limiting action to the square column 4a upper surface at dog screw 4 middle parts, and hole 3b makes to being connected the effect of stepping down in addition of nut 7 on the dog screw 4 that nut 7 is easier to be revolved tightly on it.

Can find out from Fig. 5, Fig. 6 and Fig. 7: clamping seats 5 is " " shape, and the connecting hole 5b of it and dog screw 4 is square, and is positioned at the upper table surface of " ".The square column 4a at dog screw 4 middle parts is smoothly by connecting hole 5b when being convenient to load and unload like this, and connecting hole 5b that also it goes without doing is too big, help reducing the weight of whole frock.
