Description

A load fixing clamp for a freight vehicle in which the drawn rope is automatically wound {Automatic rope clamp for truck}

The present invention relates to a load fixing clamp for a freight vehicle that firmly fixes luggage from a vehicle in order to prevent the luggage loaded in the freight compartment from falling and leaving, and more particularly, to the withdrawal of the rope, as well as tensioning or remaining The overall structure of the existing load fixing clamp, which was difficult to organize the rope, has been actively improved so that even unskilled people can use it easily and conveniently.In particular, due to the elastic force provided by the spring, the pulled rope is automatically retracted to bind the load and remain It relates not only to the arrangement of the rope, but also to the load fixing clamp for a freight vehicle in which the withdrawn rope is automatically wound, which is easy to organize and store after use, so that convenience and usability are actively guaranteed.

Usually, a load loaded in a cargo compartment of a vehicle is firmly bound to the vehicle using a rope to prevent problems such as falling or falling during driving. This rope binding method was first performed manually, and it was accompanied by a lot of effort and effort, such as fixing the knots firmly for solid support and applying tension to prevent the tied loads from shaking.

Accordingly, an automatic loading bar (aka kalkaliba) was developed, and it was possible to bind more conveniently and easily by using it. However, since the automatic loading bar is stored by winding a rope on the frame, there is a hassle of repeating unwinding and winding each time, and the withdrawal and tensioning of the rope are determined according to the direction in which the frame is bent. There was no means to present it, which sometimes caused confusion in use even by skilled workers.

On the other hand, as an example of the means for fixing the load, Registration Utility Model Publication No. 20-0479318, "Vehicle Load Fixing Device" is published, and the technology includes: a fixed belt and a variable belt having a clasp at one end of the belt belt; A fixed shaft to which the other end of the belt belt of the fixed belt is wound and coupled, a movable shaft having a slot through which the other end of the belt belt of the variable belt is inserted, and a ratchet wheel that rotates integrally with the movable shaft And, a belt fixing bracket provided with a pawl that rotates to prevent reversing of the ratchet wheel (逆轉). In the prior art, when the cargo fixing device is not provided by welding in the cargo vehicle loading box, or when it is intended to fix the cargo inside the wing body like a wing body vehicle, or when the loading box is made of aluminum alloy, or the welding attachment of the frame We propose a technology that can be used by installing the fixing device in various situations and conditions such as difficult cases.

However, the prior art is a technology that extends the installation range of the fixing device, and is a technology that deviates from the technical improvement with respect to the aforementioned withdrawal, pull-in, tension control, and arrangement and storage of the remaining rope.

As another example of the means for fixing the load, registration utility model publication No. 20-0276635 "The device for fixing the load of a cargo vehicle" is posted, and the technology includes a rope for preventing the separation of the load, and one end of the rope. A shaft to be fixed and wound, a ratchet gear integrally fixed with the shaft at one end of the shaft, and a claw supported by a bracket to be described later corresponding to the ratchet gear, and one end is fixed to one side of the shaft and the other end A configuration including a volute spring fixed to a bracket to be described later for rewinding the rope, a bracket supporting the shaft, accommodating the rope and the volute spring, and fixing the claws of the ratchet gear to a loading box. The prior art is a technology that facilitates storage and handling by automatically retracting a rope pulled out due to a volute spring.

However, the above technology is a passive structure in which the rope is pulled in and out only when the operator directly operates the handle provided on the claw, and has a cumbersome operation method of supporting the rope with one hand and operating the handle with the other hand.

In addition, since the above technology hooks the claw to a fast rotating gear, it is a natural problem that precise withdrawal of the rope is impossible.

As a result, it is not only accurate to withdraw the rope, but also to maintain the tension of the rope that combines the loads, and to arrange and fix the remaining ropes. Furthermore, after the use is completed, the pulled out rope is automatically retracted to provide convenience for use. Development is urgent.

As shown in Figure 1, the load fixing clamp of the present invention is installed by bolts or welding to the side guide of the cargo compartment, and it is natural that a plurality of the load fixing clamps are installed according to the type of the load and the user's judgment.

In particular, the load fixing clamp bears the overall weight by the bracket 400, and is firmly coupled with the cargo compartment and bolting to prevent sagging of the bracket due to such load.

As shown in Figure 2, the load fixing clamp of the present invention is made by pulling in and out of the rope 104 received in a state wound in the inner space of the case 100 due to the elastic force of the mainspring to bind the luggage loaded in the freight car, and the mainspring A structure and principle is proposed in which a rope withdrawal distance is arbitrarily controlled by a clutch 200 that selectively interferes with rotation, and a rope is automatically wound inside a case.

In more detail, the case 100 is accommodated in a wound state of the rope 104; And, the rope 104 that is accommodated in the case and is drawn in and withdrawn according to the operation of the operator; And, wound at one side of the case It is accommodated in the state, and the end portion is connected to the rope to transmit the elastic force; And, it is installed to be rotatable by the central shaft 130 at the other side of the case, and the rotation of the mainspring by the operator's arbitrary operation Clutch 300 for determining whether or not to wind the rope by interference; And, a bracket 400 that provides the height and direction of the case to be installed in the freight car; And, attached to the freight car, the binding of the luggage and fixing the remaining rope It consists of a; fixed member 500;

The case 100 is provided with a circular rope receiving unit 110 and a mainspring receiving unit 120 respectively accommodated in a state in which the rope 104 and the mainspring 200 are wound, respectively, the rope receiving unit and the mainspring The receptacle forms an outer shell along the periphery to block unwanted separation of the rope and the mainspring.

The case 100 is divided right and left with respect to the center in which the rope 104 is accommodated, and the mainspring receiving part 110 for winding and receiving the mainspring in the outer part of one divided case and the clutch assembling the outer part of the other case It is composed of a clutch receiving unit 120.

On the other hand, the central shaft 130 is installed in the center of the case 100 so that the rope is wound, and both ends of the central shaft are exposed through both sides of the case, that is, the spring receiving portion 110 and the clutch receiving portion 120, respectively. spring receiving portion, the winding is wound and accommodated, the sprinkler value receiving section is assembled, respectively, the clutch (300) according to.

Looking at the mechanism according to this coupling, when the operator pulls out the rope 104, the central axis 130 rotates with it, and as the mainspring 200 is further wound, an elastic force is formed in the mainspring, and when the withdrawn rope is placed, the wound mainspring While this is released, the rope is wound and stored in the rope receiving portion 110 together with the elastic force.

The rope 104 includes all means for stably binding the load, and the mainspring 200 includes all coil means that can be automatically wound by providing elastic force to the rope.

The rope 104 is a general component and a detailed description thereof will be omitted.

The mainspring 200 includes a rotating ring 210 that is closely disposed with the inner diameter of the mainspring receiving part 120, a spring 220 that is received in a wound state of the mainspring receiving part 120, and the outer diameter of the rotating ring. The strapping is composed of a fixing band 230, and the combination of the above-described configuration generates an elastic force that is the power of the pull-out and automatic pull-in of the rope 104.

The rotating ring 210 has a slightly enlarged diameter compared to the inner diameter of the mainspring receiving part 120, and as it is forcibly fitted to the mainspring receiving part when one area is cut and closed, the arrangement close to the inner diameter of the mainspring receiving part is It is made, and the spring receiving part is fixed by bolting the case.

The spring 220 is interconnected with the cut end of the rotating ring, and the other side is connected to the central shaft 130 exposed to the mainspring receiving unit 120, and according to the rotational movement of the central axis, the mainspring receiving unit 120 It is determined whether or not the elastic force is generated by repetitive winding and unwinding in the inner space of

The fixing band 230 encloses the outer periphery of the rotating ring to block the extension of the end of the rotating ring by the tension of the spring, and separates the rotating ring from the inner diameter of the case to reduce frictional force generated during rotation.

The fixing band 230 is provided with a fixing means of a clip fixing method at each end, so that it is possible to attempt to bind itself without a separate coupling member. The clip fixing method will be easy to understand with reference to the drawing shown in FIG. 7.

The clutch 300 is eccentrically installed at a position slightly spaced from the central axis 130, and rotates according to an operator's selective operation to interfere with the central axis, thereby stopping the rotational movement, and thus controlling and determining whether or not to withdraw the rope.

The clutch 300 includes a gear 301 that rotates concurrently with the central shaft 130, a locking member 302 that controls the rotational movement of the gear, and first and second springs 303 that select a position of the locking member. 304).

The gear 301 is installed on the upper end of the central shaft 130, and the accompanying rotation is performed according to the rotational motion of the central shaft. The gear 301 is made of a circular plate, and a plurality of protrusions are formed along the circumference at predetermined intervals, so as to have a shape of a gear as the name suggests.

The locking member 302 is installed on the side of the gear 301, and hooking with the protrusion is selectively determined according to an operator's operation to allow or control the rotational movement of the gear. The locking member 302 has one side installed so as to be rotatable in the case, and the other side has a shape corresponding to the projection of the gear 301, and when the locking member meshes with the gear, the rotation movement is blocked, and the locking member is the projection of the gear. If it deviates from, free rotational movement is allowed.
