Description

The anti-slipping chain fast assembling and disassembling device

Technical field

The utility model relates to a kind of parts of anti-slipping chain, especially relates to a kind of to the isostructural improvement of anti-slipping chain fast assembling and disassembling device.

Background technology

At present, known anti-slipping chain device is that a kind of purpose made chain is wrapped on the wheel, and then with iron wire or leather strap etc. it is tightened.Fixedly anti-slipping chain has many shortcomings in this way, the one, loading and unloading are inconvenient, moreover are the bad control of tightness, thus vehicle anti-slipping chain is loosening easily and come off in the process of moving.Chinese patent disclose a kind of vehicle skidproof chain link remover (Granted publication number: CN2137612Y), its by ratchet, ratchet, hinge silk axle, hinge silk hook, cut with scissors tight steel wire, the protection box is formed one, the anti-slipping chain interface connects with the hook form.Ratchet is made up of two parts symmetrical.Its inside is slotted.Tighten up with fixing screw.Connect equipped return spring on the ratchet, the subsidiary steel wire pressing plate of hook, the subsidiary jump ring of jump ring hook with the hank knotting axle key.Chinese patent also discloses a kind of cross-track tyre chain junction button (Granted publication number: CN 2449974Y), body is rectangle, two ends are provided with open-work, inlay card has the flexible rope button hook in this open-work, the middle part of this rectangular body outwards is convexly equipped with projection, offer through hole on the rectangular body body at projection two ends, root edge is convexly equipped with stop block.The flexible rope button hook is bending.The connecting buckle two ends are circular-arc, and appropriate location be arranged with one be beneficial to the flexible rope button hook chimeric or pull from groove.But the anti-slipping chain connecting device structure of these two kinds of structures is all comparatively complicated, makes comparatively difficult.And, cause loading and unloading to get stuck, influence use sometimes because its parts are too much.

Summary of the invention

The purpose of this utility model provides a kind of anti-slipping chain fast assembling and disassembling device, and it mainly is to solve comparatively complexity of existing in prior technology nonskid chain connector construction, makes the problem that comparatively is difficult for; The utility model also solved general adaptor union since its parts too much, cause sometimes loading and unloading get stuck, influence the use etc. technical matters.

Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:

Anti-slipping chain fast assembling and disassembling device of the present utility model comprises fixed plate and rotating plate, and fixed plate is respectively equipped with the connecting bore that is connected with the anti-slipping chain two ends with the outer end of rotating plate, it is characterized in that described fixed plate is provided with dog and pillar; The inner end of rotating plate is provided with the body that colludes that can insert in the dog, and the rotating plate middle part is provided with the arc notch that can rotate around pillar; One side of fixed plate and rotating plate is provided with mounting hole, and two mounting holes tilt to the outer end of fixed plate and rotating plate respectively.Dog colludes body on the spacing of pillar and the rotating plate and adapts to the spacing of arc notch on the fixed plate, and rotating plate colludes physical efficiency and accurately inserts in the dog on the fixed plate when pillar rotates to certain position like this, makes the chain two ends be fixed together.One skew back of fixed plate and rotating plate can be connected the link network of anti-slipping chain to the mounting hole that is provided with, and by the oblique link network of tearing, fixed plate and rotating plate can rotate round about, thereby make that colluding body deviates from dog.

As preferably, described dog side is "? " be provided with between the type, itself and fixed plate to allow and collude the cavity that body inserts.The front of dog is T-shape, the side be keep flat "? " type, the one end is affixed by attaching parts and fixed plate, forms cavity between the other end and the fixed plate.

As preferably, the angle α of the axis of described mounting hole and horizontal direction is 40～60 °, generally can be 50 °, when being convenient to tear anti-slipping chain like this, colluding body and can deviate from dog smoothly.

Therefore, it is comparatively simple to the utlity model has nonskid chain handler structure, the characteristics that manufacture craft is easy; Characteristics such as it is promptly detachable that the utility model also has the anti-slipping chain of tearing, easy to use.

Description of drawings

Accompanying drawing 1 is a kind of mounting structure scheme drawing of the present utility model;

Accompanying drawing 2 is a kind of structural representations of fixed plate;

Accompanying drawing 3 is side structure for amplifying scheme drawings of dog;

Accompanying drawing 4 is a kind of structural representations of rotating plate.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment: the anti-slipping chain fast assembling and disassembling device that this is routine, as Fig. 1, Fig. 2, Fig. 4, the fixed plate 1 and rotating plate 2 that match are arranged, fixed plate 1 is respectively equipped with the connecting bore 3 that is connected with the anti-slipping chain two ends with the outer end of rotating plate 2, is convenient to like this be connected with anti-slipping chain.As Fig. 3, fixed plate 1 be provided with a side for keep flat "? " the dog 4 of type, the one end is affixed by bolt and fixed plate, and the other end and fixed plate 1 form cavity.Also be connected with pillar 5 on the fixed plate 1.The inner end of rotating plate 2 is provided with to insert colludes body 6 in the cavity that dog 4 and fixed plate 1 form, and the rotating plate middle part is provided with can be around the arc notch 2-1 of pillar 5 rotations.The spacing of dog 4 and pillar 5 and the spacing of colluding body 6 and arc notch 2-1 adapt.Fixed plate 1 is provided with 7, two mounting holes of mounting hole respectively to the outer end inclination of fixed plate 1 with rotating plate 2 with the upper edge of rotating plate 2, and the angle α of the axis of mounting hole 7 and horizontal direction is 50 °.

During use, fixed plate 1 is installed in the two ends of anti-slipping chain respectively with rotating plate 2, and mounting hole 7 is connected near the chain of anti-slipping chain.At first anti-slipping chain is covered automobile tyre.Arc notch 2-1 blocks the pillar 5 on the fixed plate 1 on the rotating plate 2, and with the dog 4 that body 6 inserts on the fixed plate 1 that colludes on the rotating plate 2, anti-slipping chain promptly is fixed then.When wanting to dismantle, only need the chain at oblique pulling mounting hole 7 places, fixed plate 1 will be distinguished round about with rotating plate 2 and rotates, the colluding body 6 and promptly can deviate from dog 4 of rotating plate 2, thus finish dismounting.
