Description

Technical Field

[0001] The utility model relates to the technical field of nuts, and belongs to a waterproof nut capable of preventing welding slag from entering. Background Art

[0002] A nut is a cap that is screwed together with a bolt or screw to act as a fastener. Existing nuts are divided into hexagonal nuts, square nuts, butterfly nuts, round nuts, etc. The materials of nuts include carbon steel, stainless steel, brass, aluminum alloy, etc. When in use, the nut is generally screwed onto the fixed bolt or screw to connect or fasten the parts that are inserted into the bolt or screw. In various mechanical equipment, nuts are used to connect and fasten different parts to ensure the normal operation of the equipment; nuts are widely used for connection in the engine, chassis, body and other parts of the car; in building structures, nuts are used to connect steel structures, steel bars, etc. to ensure the stability of the building; circuit boards, casings and other components in electronic equipment also need to be fixed with nuts.

[0003] Existing nuts usually have threaded holes machined into the block, which can then be put on the screw for use. For example, the nut with the prior art publication number CN217401406U includes a nut body, which is configured to have threads; and a unloading groove, which is arranged on the nut body. The groove structure changes the topological structure of the bottom of the nut to change the load transfer path, so that the load on the thread is evenly distributed.

[0004] However, the above-mentioned prior art still has the following problems when used: after the nut is fixed, in order to improve the firmness of the nut and the screw, the nut usually needs to be welded and reinforced. However, a large amount of welding slag will be generated during the welding process, and some of the welding slag will fall into the internal thread of the nut through the gap, which will affect the normal use of the nut. In addition, the nut has poor sealing performance, which will cause water to flow between the nut and the screw to cause corrosion, thereby reducing the service life of the nut. Based on this, the utility model provides a waterproof nut that can prevent the ingress of welding slag. Utility Model Content

[0031] Refer to the instruction manual Figure 1-6 The present invention provides a waterproof nut that can prevent welding slag from entering, including a nut body 1, the nut body 1 including a nut rotating portion 101 and a nut fixing portion 102, the nut fixing portion 102 being fixed to the front end of the nut rotating portion 101, the front end of the nut fixing portion 102 being fixedly provided with an annular protrusion 103, the nut rotating portion 101, the nut fixing portion 102 and the annular protrusion 103 being integrally formed, a threaded hole 104 being provided inside the nut rotating portion 101, a tapered hole 2 being provided at the center of the front end of the nut fixing portion 102, a tapered hole 2 being provided at the rear end of the nut rotating portion 101, the tapered hole 23 and the tapered hole 2 being connected to the threaded hole 104;

[0032] In addition, the cross-section of the annular protrusion 103 is set to be an isosceles trapezoid, and the bottom surface of the annular protrusion 103 is coated with red paint. When the nut fixing part 102 is in full contact with the object, the staff cannot see the red paint from the side, thereby ensuring that the nut body 1 is tightened into place. The inner wall surface of the tapered hole 1 2 and the inner wall surface of the tapered hole 2 3 are both fixed with a rubber sealing ring 4. The use of the rubber sealing ring 4 in the tapered hole 1 2 can improve the sealing performance of the nut fixing part 102, and the rubber sealing ring 4 in the tapered hole 2 3 can improve the sealing performance of the nut rotating part 101.

[0033] The waterproof nut consists of a nut rotating part 101 and a nut fixing part 102. When in use, align the tapered hole 102 on the nut fixing part 102 with the screw and screw it in until the annular protrusion 103 at the bottom of the nut fixing part 102 contacts the object. The staff judges that the nut body 1 is tightened into place by observing the appearance of the red paint. The annular protrusion 103 is used to seal the bottom of the nut fixing part 102, which can not only play a waterproof role, but also prevent welding slag from entering the inside of the nut body 1 and affecting the connection between the nut body 1 and the screw.

[0034] Refer to the instruction manual Figure 1-6 The outer wall of the nut rotating part 101 is provided with a rotating assembly 5, and the rotating assembly 5 includes a plurality of dial plates 501. The outer wall surface of the nut rotating part 101 is provided with a plurality of grooves 502. The plurality of grooves 502 are distributed in a ring array on the outer wall surface of the nut rotating part 101. The plurality of dial plates 501 are respectively rotated in the plurality of grooves 502. The plurality of dial plates 501 can be used to facilitate the staff to manually tighten the nut body 1 for fixing. When not in use, the dial plates 501 are flipped into the grooves 502, so as to avoid the protrusion of the dial plates 501 affecting the beauty of the nut body 1.

[0035] Furthermore, a plurality of clamping blocks 6 are fixedly provided on the outer wall of each dial plate 501, and a plurality of clamping slots 7 are provided on the inner wall of each groove 502 to match the clamping blocks 6.

[0036] By arranging multiple dial plates 501 on the outer wall of the nut rotating part 101, when the nut body 1 is rotated, the multiple dial plates 501 are flipped open in turn. The staff can manually rotate the nut body 1 with the help of the dial plates 501. After it is rotated into place, the multiple dial plates 501 can be flipped and reset.

[0037] Refer to the instruction manual Figure 1-6A plurality of circular holes 8 are provided on the outer wall surface of the nut fixing portion 102. The plurality of circular holes 8 are distributed in a circular array on the outer wall surface of the nut fixing portion 102. Two adjacent circular holes 8 are connected. By passing the shift rod through the circular hole 8, the staff can rotate the nut body 1 with the help of the shift rod, which is more time-saving and labor-saving to use. At the same time, it can also increase the force for rotating the nut body 1, thereby improving the stability of the nut body 1.

[0038] Two rubber sealing plugs 9 are inserted into each circular hole 8, and a shift block 10 is fixed on each rubber sealing plug 9 to facilitate the staff to take the rubber sealing plug 9.

The plurality of slots 11 are distributed in a circular array on the outer wall surface of the nut fixing part 102, and the plurality of slots 11 are spaced apart from the plurality of circular holes 8. When the circular hole 8 is used to install the shift rod, the staff can pull the rubber sealing plug 9 out of the circular hole 8 and then insert it into the slot 11, thereby avoiding the loss of the rubber sealing plug 9;

[0039] A plurality of circular holes 8 are provided on the outer wall surface of the nut fixing portion 102. The staff first grasps the shift block 10 to pull out the rubber sealing plug 9 in the circular hole 8, and inserts the taken-out rubber sealing plug 9 into the slot 11 at the same time, and then inserts the shift rod into the circular hole 8 to drive the nut body 1 to rotate, thereby assisting the staff in rotating the nut body 1. The structure is simple and it is more time-saving and labor-saving to use.

[0040] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention.
