Abstract

The utility model provides a novel pry bar of a hand-operated winch. The utility model belongs to the field of mechanical technology and relates to the novel pry bar used on the hand-operated winch. The problem that the existing pry bar can be easily disengaged from pry bar holes in the process of utilization can be solved. The novel pry bar of a hand-operated winch comprises one strip-shaped bar body, wherein the front part of which is hinged with one hasp, wherein the head of which forms a hook shape. A spring is arranged between the hasp and the bar body. When the novel pry bar is used, the front end of the bar body is inserted into one pry bar hole. The head of the hasp is clamped into the other pry bar hole. Thus, the pry bar can not be disengaged from the pry bar holes in the process of wrenching a belt shaft. Therefore, convenience is provided for the operation of the hand-operated winch. The pry bar can be wrenched by one single hand for operation. Meanwhile, because the bar body can not be disengaged from the pry bar hole, bruise for a user due to bar body falling can be prevented. Therefore, the utility model can be safely utilized.

Description

The novel crow bar of Hand winch

Technical field

The utility model belongs to field of mechanical technique, relates to a kind of novel crow bar that uses on Hand winch.

Background technology

In automobile carried cargo process, goods needed binding usually.Though the mode that adopts rope directly to bundle is in daily use, wastes time and energy, and be difficult to goods is bound.Hand winch is a kind of advanced person's a binding tools, can make things convenient for and restraint of loads apace by it.

As shown in Figure 4, Hand winch comprises a support 6 and is loaded on a tape spool 7 on the support 6, tape spool 7 can rotate and on tape spool 7 volume winding is arranged.When restraint of loads, crow bar inserts the crow bar hole 71 on the tape spool 7, pulls crow bar and drives tape spool 7 rotations, thereby winding is tightened up, and goods is bundled on the automobile securely.

When using the Hand winch restraint of loads of existing structure, crow bar usually occurs and break away from the crow bar hole, make that the user must be very careful when operation.Simultaneously, crow bar breaks away from the crow bar hole and also may cause some potential safety hazards.

Summary of the invention

The purpose of this utility model is existing the problems referred to above of crow bar of using on the existing Hand winch, and a kind of novel crow bar of Hand winch is provided, and makes it can not break away from the crow bar hole when operation, thereby has easy to operate, safe and reliable characteristics.

The purpose of this utility model can realize by following technical proposal: the novel crow bar of this Hand winch comprises the barred body of a bar shaped, it is characterized in that, anterior hinged one of described barred body has contact with, and the head that has contact with is hook-type, have contact with and barred body between be provided with spring.

Match with this novel crow bar, the end of stretching out winch bracket at tape spool has four crow bar holes.This novel crow bar inserts in the barred body front end in one of them crow bar hole in use, and the head that has contact with is located to another crow bar hole along the surface sliding of tape spool simultaneously, and snaps under the effect of spring in this crow bar hole.At this moment, barred body just can't come off the crow bar hole.Like this, can pull crow bar very relievedly, winch is operated.

In the novel crow bar of above-mentioned Hand winch, described barred body and have contact with between a joint is arranged, joint and barred body are connected, the middle part of having contact with is hinged by bearing pin on the joint and barred body.

In the novel crow bar of above-mentioned Hand winch, described spring is a torsion spring.

In the novel crow bar of above-mentioned Hand winch, described spring is fixed on the joint, and the two ends of spring act on barred body respectively and have contact with.Under the effect of spring, make the head that has contact be affixed on the front end of barred body.

Compared with prior art, the mode of having contact with is set up in the utilization of this Hand winch, makes crow bar can not break away from the crow bar hole in pulling the tape spool process, brings convenience therefore for the operation of Hand winch.In fact, as long as just can pulling crow bar, operates one hand.Simultaneously,, avoided barred body to come off and injured the user by a crashing object, so safe and reliable in use because barred body can not break away from the crow bar hole.

Fig. 1 is the structural representation of novel crow bar hook on tape spool of this Hand winch.

Fig. 2 is that the novel crow bar of this Hand winch does not have the structural representation of hook when tape spool.

Fig. 3 is the structural representation with the corresponding Hand winch of the utility model.

Fig. 4 is the structural representation of common manual winch.

Among the figure, 1, barred body; 2, have contact with 21, head; 22, afterbody; 3, joint; 4, spring; 5, bearing pin; 6, support; 7, tape spool; 71, crow bar hole.

The specific embodiment

As depicted in figs. 1 and 2, the novel crow bar of this Hand winch comprise barred body 1, have contact with 2, joint 3, spring 4 and bearing pin 5.Barred body 1 is bar shaped, adopts metallic material to make.On barred body 1, be welded with joint 3.Have contact with 2 front portions that are positioned at barred body 1, its head 21 is hook-type, has contact with 2 middle part and is articulated on the joint 3 by bearing pin 5.Be provided with a spring 4 at barred body 1 and between having contact with 2, spring 4 is fixed on the joint 3, and the two ends of spring 4 act on barred body 1 respectively and have contact with on 2.In the present embodiment, what spring 4 adopted is torsion spring.

As shown in Figure 3, match with this novel crow bar, the external part of tape spool 7 has 71, four crow bar holes 71, four crow bar holes and is uniformly distributed on the tape spool 7 in winch.

As depicted in figs. 1 and 2, in use, barred body 1 front end is inserted in the crow bar hole 71, have contact with 2 hook head 21 surface sliding along tape spool 7.When another crow bar hole 71 is arrived in hook head 21 slippages, under the effect of spring 4 tension force, embed in the crow bar hole 71, and hook crow bar hole 71.Like this, barred body 1 can't come off from crow bar hole 71, pulls barred body 1 and just can operate Hand winch.

After pulling barred body 1 and driving tape spool 7 rotating certain angle, have contact with 2 afterbody 22 as long as push, make and have contact with 2 head 21 and break away from crow bar holes 71, just can extract barred body 1 out, insert in and continue to drive tape spools 7 rotations in another crow bar hole 71.Repeat aforesaid operations,, Goods binding is lived until winding is tightened up.
