Description

Technical Field

[0001] The utility model relates to the technical field of metal products, in particular to a high-wear-resistant metal product. Background Art

[0002] "Metal products" is a broad term that refers to various items and products made of metal materials. Metal products can include but are not limited to the following aspects: household items, building materials, transportation vehicles and equipment, industrial equipment and machinery, electronic equipment and medical devices, etc. Wrenches are also a type of metal products. A wrench is a tool used to tighten or loosen bolts and nuts. It is usually made of metal and has heads of different shapes and sizes to accommodate bolts and nuts of different specifications. The main function of a wrench is to provide a handle that allows the user to apply torque to rotate a bolt or nut.

[0003] In the field of locomotive maintenance, the most basic requirement is that the aviation plug connection is securely fastened. If the plug is not tightened in place, it will lead to a loose connection in the line, which is very easy to burn the locomotive electrical components and eventually cause the machine to break. Since there are many aviation plugs arranged side by side with very small gaps between them, it is difficult to circle the wrench after inserting it. It can only be twisted to a certain angle, removed and twisted again, which makes it troublesome to disassemble and tighten the plug.

[0004] Therefore, the utility model provides a highly wear-resistant metal product to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Example

[0034] Reference Figure 1-5 The utility model provides an embodiment: a highly wear-resistant metal product, including a first clamping part 1, a second clamping part 2, two detachable clamping plates 3 and a handle 4, a groove 18 is opened on one side of the first clamping part 1, a fixing rod 17 is fixedly arranged between the upper and lower inner walls of the groove 18, and a second sleeve 15 is fixedly arranged on one side of the handle 4.

[0035] The wrench is provided with a fixing rod 17 on one side of the first clamping part 1, and a handle 4 is movably mounted on the fixing rod 17. The handle 4 can be turned so as to form a right angle with the first clamping part 1. For a plug in the middle position of a row of plugs, the wrench can be directly inserted into the gap. The handle 4 can be directly held upright and turned for a circle to disassemble or tighten the plug. There is no need to repeatedly remove and reinstall the wrench, which is more convenient for disassembling and tightening the plug.

[0036] A first sleeve 11 is fixedly provided on one side of the upper end surface of the second clamping part 2, an inner groove 9 is opened at the upper part of one side inside the first clamping part 1, a through groove 12 is opened at the upper part of one side of the first clamping part 1, a screw 10 is rotatably provided between the inner wall on the opposite side of the through groove 12 and the inner groove 9, the first sleeve 11 and the screw 10 are threadedly sleeved, a slide groove 8 is opened on the opposite side of the first clamping part 1 and the second clamping part 2, a slider 6 is fixedly provided on one side of the detachable clamping plate 3, a plurality of convex teeth 5 are fixedly provided on the other side of the detachable clamping plate 3, and the slider 6 is slidably provided inside the slide groove 8.

[0037] By providing a detachable pliers plate 3, since a convex tooth 5 is provided on one side of the detachable pliers plate 3, the convex tooth 5 can increase the friction between the pliers plate and the plug, making the removal and tightening of the plug more convenient. Due to the provision of the convex tooth 5, the wrench is prone to wear after being used for a period of time. The detachable pliers plate 3 between the first clamping part 1 and the second clamping part 2 can be replaced, thereby increasing the service life of the wrench.

[0038] The first clamping part 1 includes a base layer 101, and wear-resistant layers 102 are fixedly provided on both the upper and lower sides of the base layer 101. The second sleeve 15 is movably sleeved with a fixed rod 17. A plurality of tooth blocks 16 are fixedly provided around the second sleeve 15. A clamping block 14 is fixedly provided on the inner wall of one side of the groove 18. Bolts 7 are provided on the opposite sides of the first clamping part 1 and the second clamping part 2. The opposite sides of the two bolts 7 respectively penetrate into the inside of the slide groove 8. A rotating block 13 is fixedly sleeved on one side of the screw rod 10. The front and rear sides of the rotating block 13 respectively penetrate into the front and rear sides of the through groove 12. The wear-resistant layer 102 is set to a tungsten carbon coating.

[0039] By providing the wear-resistant layer 102, the first clamping part 1 has high wear resistance and a longer service life. The materials used for the first clamping part 1 are the same as those used for the second clamping part 2, the detachable clamp plate 3 and the handle 4. By providing a plurality of tooth blocks 16 around the second sleeve 15 and providing a block 14 on the inner wall of one side of the groove 18, the handle 4 can be limited to a certain extent. By providing the bolt 7, the slider 6 can be limited by the bolt 7 when it slides into the inside of the slide groove 8. By fixing the rotating block 13 around the screw rod 10 and passing the through groove 12 at the front and rear ends of the rotating block 13, the size of the opening between the first clamping part 1 and the second clamping part 2 can be adjusted by rotating the rotating block 13. The tungsten carbon coating has excellent hardness and wear resistance and can maintain stability under high temperature and high pressure conditions. A through hole 19 is provided on one side of the front end surface of the handle 4. The through hole 19 is provided to facilitate the hanging of the wrench.

[0040] Working principle: When the wrench is in use, the screw 10 is rotated by rotating the rotating block 13 so that the openings of the first clamping part 1 and the second clamping part 2 are opened. After inserting it on the plug, the first clamping part 1 and the second clamping part 2 clamp the plug by rotating the rotating block 13, and then the plug is removed or tightened by rotating the handle 4. If the space is small, the handle 4 can be erected and bent for one circle to remove or tighten the plug. If the convex teeth 5 are worn after long-term use, the bolts 7 can be removed to remove the detachable clamp plate 3 and replace it with a new one.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
