Abstract

The utility model belongs to a locking device for a tarpaulin. The utility model adopts that a locking spring is arranged on a casing, a wheel drum which is wound with a rope is arranged outside the spring, and the rope is connected with a locking hook outside the casing through a pulley drum. A locking ratchet wheel and a driven wheel are arranged on the lower end of the wheel drum, the locking ratchet wheel is jointed with a locking ratchet pawl on a pulley shaft, and the driven wheel is meshed with a manual fastening gear; two ends of an annular rope sleeve are fixed on a shaft rod on the end of the casing, and the other end of the annular rope sleeve forms a locking ring outside the casing. Because the utility model adopts an anti-drop hook and a wire rope, the utility model can not loose and can not be cut off easily to cause safety and reliability to be improved.

Description

A kind of automobile-used tarpaulin locker

The utility model relates to a kind of other machinery, device or method of packaged or material, particularly a kind of automobile-used tarpaulin locker.

Train, automobile are in transportation, and a lot of goods need cover with tarpaulin, and to the locking of tarpaulin, use common rope (rope made of hemp, the nylon rope) bondage that manually knots for a long time.This method troublesome poeration is wasted time and energy, and the easy again loose or dislocation of sling.Cut off by the people easily again, cause tarpaulin, rope and loss of goods.Only with regard to Tiedaobu Transportation Bureau statistics, annual because tarpaulin rope gets loose to drift with car and breaks rail facility, and rope is cut off nearly 1,500 ten thousand yuan more than of the loss that causes.The loss that vehicular transport causes therefrom still can't be added up.For this reason, can Tiedaobu Transportation Bureau just propose several years ago and used rope is cancelled to address the above problem.The design of this locker is just at the problems referred to above and concept development.Be intended to make the locking problem of tarpaulin to become convenient and swift time saving and energy saving, safe and reliable.

The purpose of this utility model provides a kind of tarpaulin locker that is used for goods transport.

The utility model is achieved in that a kind of tarpaulin locker is to adopt a housing, has a case lid at the housing another side, has a locking main shaft in the centre of housing, an end of fixing spring on the locking main shaft, the other end is fixed in the wheel hub groove, on wheel hub, be wound with rope, one end of rope is fixed on the wheel hub, the other end is by the pulley drum, outside housing, be fixedly connected with the locking hook, lower end at the locking main shaft has a locking ratchet, lower end at the locking ratchet has a flower wheel, crescent locking ratchet interlock on locking ratchet and the sheave shaft, flower wheel is meshed with manual fastening teeth wheel on the manual fastening teeth wheel shaft, has a fixed axostyle at housing one end, the two ends of stationary annular noose on fixed axostyle, the other end constitutes lock ring outside housing, has a sheave shaft at the housing other end, on sheave shaft, have pulley drum and crescent locking ratchet, has a ratchet pressure position spring that touches mutually with the crescent locking ratchet in housing the inner, have a cam lock and protect groove on case lid, have a camshaft in cam lock protects groove, camshaft has a ratchet lock cam on enclosure interior.

This locker is fixed on the corresponding position of car body, with spanner camshaft is rotated during use, ratchet is thrown off, pulling locking is linked up with then, involve steel rope to needs length, to link up with and advance in the tarpaulin lockhole or goods other end respective fixation position, when affecting steel cable, by rope sheave spring is tightened automatically, make steel rope be in tensile state, enter lockhole or respective fixation position as long as will link up with like this, this locker enters mode of operation naturally, with spanner camshaft is gone to original position at last, promptly finish whole operating process.Use the back as long as hook is taken, under the effect of spring, in the steel cable automatic drawing back housing, be in stand-by state.

The utlity model has each intensity all above the intensity of now using the tarpaulin rope, satisfy fully and use needs.And it is very convenient to operate, and only needs the time in several seconds can finish whole operations.From security standpoint, owing to adopt anticreep hook and steel rope, neither can get loose, can't cut off easily again, this has improved safety and reliability greatly.Since the effect of spring, the control of reverse ratchet in addition, in transportation, when goods sinks to causing tarpaulin to relax, this locker energy auto lock, and can not loosen.

Concrete structure of the present utility model and embodiment are provided by the following drawings.

Fig. 1 is an external structure scheme drawing of the present utility model;

Fig. 2 is A～A sectional structure scheme drawing of Fig. 1;

Fig. 3 is B～B sectional structure scheme drawing of Fig. 2.

Below in conjunction with accompanying drawing overall structure of the present utility model and embodiment are done with further instruction.
