Description

The four-wheel position finder anchor clamps

Technical field

The utility model relates to a kind of anchor clamps, particularly a kind of four-wheel position finder anchor clamps.

Background technology

The four-wheel location is meant vehicle body, the certain mutual alignment relation that is had between wheel and the ground, the variation of the data that they are all is when being horizontal by car, tire shape and tire situation of living in reflects, this data owner will record by four-wheel position finder, four-wheel position finder is by sensor is clipped on the wheel by anchor clamps, sensor just can record the data of four-wheel location, and whether sensing data is accurate, depend on whether sensor axis is consistent with the tyre rim center of circle, and the sensor axis core interts in anchor clamps centre mount hole, therefore must reduce or reduce the variation in anchor clamps centre mount hole.

And existing four-wheel position finder anchor clamps mainly comprise as Fig. 1, tripod 1 shown in Figure 2 and chuck 2 two parts, this tripod 1 comprises the tripod main body 11 shown in the figure, tripod centre mount 12 is installed on tripod main body 11, tripod centre mount 12 tops are provided with thread bush 14, insert centre mount core retainer plate 15 in the middle of the tripod centre mount 12, the axle core of sensor is inserted in the described centre mount core retainer plate 15.The structure of described chuck 2 as shown in Figure 2, chuck mainly comprises the disk 21 of central authorities, the bending wheel hook assembly 23 that stretches out in the disk both sides, the length of wheel hook assembly 23 can be regulated, it is clipped on the wheel, 21 central authorities protrude upward axis screw 26 from disk, and this axis screw 26 upwards is connected with centre mount core retainer plate 15 on the tripod 1.

In use, when being fixed to tripod 1 on the chuck, axis screw on the chuck 26 to be screwed in the centre mount core retainer plate 15 of tripod 1 from below, the process that turns realizes by the thread bush 14 on the rotation tripod 1, because centre mount core retainer plate 15 on the tripod and the axis screw 26 on the chuck can not coincide flawlessly by rotation, always have some gaps, can strengthen the degree of eccentricity of centre mount core retainer plate 15, so can influence measurement result.

Simultaneously, in the centre mount hole of the centre mount core retainer plate 15 of axle core insertion tripod 1 upper end of sensor (not shown), suitably rotate thread bush 14 sometimes, make it reach firmly stable, this just makes and produces friction between sensor axis core and the seat hole, use the long period, gap between the two will increase, and also can influence measurement result.

And the parts explosion of the wheel hook assembly 23 on the chuck shown in Fig. 3, mainly comprise two sections, the inner segment side of being hook 231, its upper surface is provided with a row, and several stop groove 232, outer section is crooked wheel hook 233, the side that side's hook 231 inserts on wheel hook 233 the inners is overlapped in 238, and side's cover 238 upper surfaces have hole 236, the hinged hook enclosing cover 234 of taking turns on square hole, between wheel hook enclosing cover 234 and side's cover upper surface, spring 235 is set, at the opposite side of the jointed shaft relative with described spring, insert screw 237 trailing wheel hook enclosing covers 234 tops, and screw 237 is fixed on the wheel hook and covers outward, and the lower end extend into by hole 236 and stops in the groove 232, play position-limiting action, when needing the length of regulating wheel hook assembly, press an end of lower whorl hook enclosing cover 234 installing springs 235, compression spring 235, screw 237 1 ends have been lifted up, from stop groove 232, break away from, then can regulate its length, but it has only a row to stop groove 232, so a period of time is used in easily wearing and tearing, the time have card not live phenomenon.

Summary of the invention

The utility model has overcome the chuck of existing four-wheel position finder anchor clamps and centre mount core retainer plate that tripod makes sensor installation easily produces shortcoming eccentric, that influence measurement result, when a kind of installation chuck and tripod are provided, can not influence the four-wheel position finder anchor clamps of sensor.

In order to achieve the above object, four-wheel position finder anchor clamps of the present utility model, comprise tripod and chuck, described tripod comprises the tripod main body, the tripod centre mount is installed on the tripod main body, the sensor installation thread bush is set on the tripod centre mount, described chuck comprises the disk of central authorities, stretch out the bending wheel hook assembly that is used to clamp wheel in the disk both sides, disk central authorities protrude upward the axis screw, the adjusting circle wheel that is provided with bearing is installed in tripod main body upper end, described adjusting circle is taken turns central authorities and is shaped on threaded hole, described axis screw inserts from downside and matches with threaded hole, in the A-frame of regulating above the circle wheel, regulate between circle wheel and the A-frame being separated at tripod main body upper holder, described part is regulated the circle wheel and is exposed to outside the A-frame, thread bush is arranged at the upper end of described A-frame, is provided for the tripod stand fuse of sensor installation in described thread bush.

The described hook assembly side of the comprising hook of taking turns, the wheel hook, be shaped on several respectively in wheel hook two sides and stop groove, side's hook and wheel hook insert respectively F type wheel hook web member fasten form on, in following two slots, described side's hook is fixedlyed connected with wheel hook web member, side at two the wheel hook web members relative with the wheel hook has the hole, after the centre is shaped on the sheathed spring of bayonet lock of expansion section, in described hole, pass respectively, the button that bayonet lock outside external part and middle inboard are provided with outstanding fulcrum is hinged, spring is under state of nature, and the inner termination of bayonet lock can place described stopping in the groove.

Four-wheel position finder anchor clamps of the present utility model, when its tripod is connected with chuck, as long as the axis screw on the chuck is inserted in the threaded hole of regulating on the circle wheel, rotate again and regulate the circle wheel, being screwed to the appropriate location gets final product, and adjusting circle wheel does not contact with the thread bush of top, can not influence being connected of thread bush and sensor so rotate to regulate the circle wheel, that is: can not make sensor off-centre, thereby can reduce the wearing and tearing between fuse and the seat hole, prolonged serviceable life, sensor is fixing more firm simultaneously, and the data that record are more accurate.

Four-wheel position finder anchor clamps of the present utility model, it is taken turns and is hooked in when regulating length, uses both sides fastening respectively, and institute is so that card ends more firm, durable.
