Description

Towing shipping tester

The present invention relates to a toe-shipping tester, and more particularly, to a towing-shipping tester for adjusting the angle of the cylinder by a worm gear method by escaping the screw type angle adjusting method of the existing cylinder. Due to this feature, it is intended to improve the durability of the towing shipping tester device and to facilitate the adjustment of the angle to increase the working convenience.

In general, a hook is coupled to a back beam of a mass produced automobile bumper. These hooks are used to be combined with a tow vehicle in a vehicle accident, and also used to secure the vehicle to a ship when shipped by ship.

Towing combined with a tow truck is called towing, and shipping and fixing on a ship is called shipping.

In order to check whether the towing shifting function of the vehicle can be normally performed, a towing & shipping tester is used. The towing shipping tester connects the wire to the hook of the vehicle and couples it to the cylinder of the tester, and tests the strength and durability by applying a multi-directional force to the hook by adjusting the up and down angle of the cylinder.

1 is a perspective view of a conventional toe shipping tester, and FIG. 2 is an enlarged view of a screw portion of a conventional toe shipping tester. Hereinafter, referring to FIGS. 1 and 2, the angle adjusting method of the conventional toe shipping tester will be described, and the problem will be described.

The conventional toe-shipping tester includes a main body 1, a cylinder 2, a hook 3, a screw 4 and a screw coupler 5.

The cylinder 2 has a shape extending in the longitudinal direction and is rotatably coupled to the main body 1. In addition, the hook 3 is coupled to the end of the cylinder 2. Hook 3 is coupled to the connecting line not shown, it is connected to the hook formed in the vehicle. For this reason, when the cylinder 2 rotates upwards, the hook formed in the motor vehicle is forced upward by a connecting line having a predetermined angle with the ground. For example, it may be 15 degrees.

In addition, when the cylinder 2 rotates downward, the hook formed in the motor vehicle is forced downward by a connecting line having a predetermined angle with the ground.

With this angle adjustment, it is possible to apply strength to the hook in various directions to test the strength and durability.

At this time, conventionally, the screw thread formed in the screw coupler 5 and the screw thread of the screw 4 penetrating the screw coupler 5 are engaged with each other, and thus, the screw 4 according to the rotational direction of the screw 4 is engaged. A structure is formed in which elevates or descends. Therefore, the operator bites a separate jig on the head 6 formed at the tip of the screw 4, thereby applying a movement in the vertical direction to the screw 4, thereby allowing the cylinder 2 to be coupled with the screw 4. Angle adjustment can be performed.

However, in the conventional method, when the screw 4 is rotated, there is a problem that excessive force is generated in the screw coupling table 5 engaged with the screw 4. This is because a structure in which a hole formed in the screw coupler 5 is formed to surround the entire screw 4 is formed, so that the screw thread formed in the screw 4 and the screw coupler 5 is large in contact with each other. For this reason, a force is applied to the entire body 1 coupled to the screw coupler 5, and there is a problem that the angle of the cylinder 2 is not smoothly adjusted.

In addition, when fatigue due to rotation is accumulated, there is a problem in that the screw thread formed on the screw coupler 5 or the screw 4 is worn and the lifting and lowering of the screw 4 in the vertical direction is not performed smoothly.

The rotating shaft 111 passes through the first housing 110 and the cylinder part 200 extending in the longitudinal direction at the same time.

As a result, the cylinder part 200 is tilted in the vertical direction about the rotation axis 111. In the present invention, the tilting movement in the vertical direction means that the cylinder part 200 is parallel to the ground, and rotates upward while having a predetermined angle with the virtual line about an imaginary line passing through the rotation axis 111. Or it refers to the movement to rotate downward while having a predetermined angle with the virtual line.

The second housing 120 protrudes forward from the bottom of the first housing 110. The second housing 120 is formed with a space spaced apart by a predetermined length in the width direction, the guide portion 700 to be described later is located inside the space.

As will be described later, since the first connection portion 300 is not directly coupled to the cylinder 210, but coupled through the cover 220, the durability of the toe-shipping tester is increased.

The first connection part 300 is coupled to the lower part of the cover 220. The first connector 300 includes a support 310, a link 320, and a support shaft 330. The support 310 is formed with a space spaced apart at a predetermined interval in the width direction, the upper surface is directly coupled to the cover 220. The link 320 is inserted between the support 310, and the support shaft 330 passes through the support 310 and the link 320 simultaneously.

As a result, the link 320 can be rotated forward and backward with respect to the support shaft 330. In addition, since the link 320 is connected to the first worm gear part 400, the first connection part 300 and the first worm gear part 400 are hinged.

Therefore, the cylinder part 200 can rotate in response to the rising and falling of the first worm gear part 400 in the vertical direction. In more detail, when the first worm gear part 400 is elevated in the vertical direction, the cylinder part 200 rotates upwardly about the rotation axis 111, and the first worm gear part 400 is in the vertical direction. As it descends, the cylinder part 200 rotates downwardly about the rotation axis 111. Description thereof will be described later with reference to FIGS. 6 and 7.

As a result, the angle of the cylinder portion can be adjusted as much as the vertical movement of the first worm gear part 400 is performed, thereby setting and testing a desired angle.

FIG. 5 is an enlarged view of a portion in which a first worm gear part and a second worm gear part are engaged with each other in a towing shipping tester according to the present invention. Hereinafter, with reference to FIG. 5, the configuration and effects thereof of the first worm gear unit 400 and the second worm gear unit 500 will be described.

At this time, the first worm gear part 400 and the second worm gear part 500 are meshed to be orthogonal to each other. More specifically, the bar 420 of the first worm gear unit 400 and the handle shaft 520 of the second worm gear unit 500 are positioned to be orthogonal to each other, and the thread 421 of the first worm gear unit 400 is located. And teeth 511 of the second worm gear part 500 mesh with each other.

This structure is called the 'worm gear' method. When the operator rotates the handle 530, the bar 420 can be raised and lowered in the vertical direction. In addition, there is a direction, when the handle 530 is rotated in one direction, the bar 420 is elevated in the vertical direction, when the handle 530 is rotated in the opposite direction of the one direction, the bar 420 is vertical There is an advantage that the work convenience is increased by falling in the direction.

In addition, such a worm gear system can obtain a large reduction ratio, which has the advantage of allowing fine adjustment of the towing shipping tester.

In addition, in the case of the conventional toe-shipping tester, the entire screw 4 is wrapped around the screw coupler 5, so that excessive force is generated during the rotation process, thereby exerting excessive force on the entire tester. However, according to the present invention, the tooth 511 is in contact with the thread 421 formed on the bar 420 only a part of the surface can solve the conventional problem, it is seen through a separate handle rather than turning the screw 4 itself Since the bar 420 corresponding to the screw 4 of the present invention is moved in the vertical direction, there is an advantage in that work convenience and work efficiency are increased.

The second connection part 600 penetrates through the gear case 410 and the second housing 120 at the same time. At this time, the gear case 410, the axis of the second connecting portion 600, it is possible to rotate the front, rear.

Due to this configuration, when the cylinder part 200 rotates upward as shown in FIG. 7, the gear case 410 rotates forward, and the cylinder part 200 rotates backward as shown in FIG. 8. In this case, the gear case 410 rotates backward.

Therefore, the rotational movement of the cylinder part 200, the upward movement, the downward movement of the bar 420, and the rotational movement of the gear case 410 are all organically coupled. For this reason, any one component is not released during the test, thereby increasing the safety of the operator, and the force applied to the main body 100 is dispersed, thereby increasing the durability of the tester.
