Springs are assembled on the stopping and retreating pawls; a rotary support is connected with the fixing support in rotation. Rotary pawls are connected with the rotary support in slide; springs are assembled among the rotary pawls and the rotary support. The utility model has the advantages of convenient and fast operation, firm binding, time and labor saving, and easy operation.

Description

Draw the car device

The utility model belongs to a kind of lorry and draws the car device, particularly a kind of easy to operate, draw the car device efficiently.

Be restraint of loads at transit industry at present, it is fixing to tie a knot after mostly adopting rope that goods is drawn, and this orthodox method effort is time-consuming, is difficult for simultaneously goods is bound, and rope is loosened and also will be tied a knot again in transit.

The purpose of this utility model provides a kind of stroke of car device, and is easy to operate, quick, bundle solid, time saving and energy saving, easy operating.

The purpose of this utility model is achieved in that it comprises the fixed support that is connected with hook, and its technical scheme main points are: rotate the two-semiaxle that interpolation slit is set in the middle of connecting on the fixed support.Ratchet is fixedly connected on the two-semiaxle; Be slidingly connected the retaining ratchet on the fixed support, assemble spring on the retaining ratchet; Swinging strut is rotatably connected on the fixed support, is slidingly connected rotary pawl on the swinging strut, assembles spring between rotary pawl and the swinging strut.

Principle of work a: side that tie one end of restraint of loads is fixed on the transportation lorry, the tie other end is inserted in the interpolation slit between the two-semiaxle, hook is hooked on the compartment, rotate swinging strut then, swinging strut driven rotary ratchet rotates together, the rotary pawl driving pawl clockwise rotates, and this moment, two-semiaxle also rotated thereupon.When ratchet forwarded certain circumference to, swinging strut returned the initial position, and this moment, the retaining ratchet stoped ratchet and two-semiaxle not to rotate by conter clockwise, rotary pawl slides along the domatic tooth of ratchet, repeat next action again, tie is wrapped on the two-semiaxle, is bound until goods.

The utility model has the advantages that: easy to operate, quick, bundle solid, time saving and energy saving, easy operating.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 7 is the fixed support scheme drawing.

See Fig. 1-7.Concrete structure is as follows: fixed support 4 one ends that metal sheet is made connect hook 1 by short nylon tape 2 and axle 3; Middle part sliding eye 18 and both sides sliding eye 19 are set on the fixed support 4, and the sliding handle of retaining ratchet 6 is inserted in the sliding eye 18 of middle part, and both sides are inserted in the both sides sliding eye 19 of fixed support 4; Pocketed springs 5 on the sliding handle, and the other end of fixed support 4 rotates and connects two-semiaxle 10, between the two-semiaxle 10 interpolation slit is set, and two-semiaxle 10 two ends are fixedly connected assembled washer 8 between fixed support 4 and the ratchet 7 with the ratchet 7 that is assembled in the fixed support outside; Swinging strut 14 turning sets that metallic sheet material is made are contained in two-semiaxle 10 two ends, and the outermost end of two-semiaxle 10 is installed and connected pin 9.Swinging strut 14 has two blocks of side plates, connects one by screw rod 12 and handle 15.See Fig. 6, have slide opening 17 on the biside plate, the two side ends of rotary pawl 13 is inserted into and realizes in the slide opening 17 sliding.Assembling dialing spring formula spring 11 between swinging strut 14 and rotary pawl 13.See Fig. 2,6,7, on fixed support 4 and swinging strut 14, be equipped with cam segment 16,, promptly broken away from ratchet 7, thereby the tie of binding is unclamped when retaining ratchet 6 and rotary pawl 13 are sliding when going up this section and going up.

Claims (3)
