Description

Technical Field

[0001] The utility model relates to the technical field of hole formation detection of squeezed branch piles, in particular to a bolt with an anti-loosening function. Background Art

[0002] Bolts are the most commonly used basic standard mechanical parts. Together with nuts, they can achieve the fastening connection between two parts with through holes. They are usually composed of a head and a screw. However, after the bolts fasten the two parts, they are prone to loosening or even falling off after long-term use, especially bolts on parts that are working dynamically or vibrating, causing the parts to be easily damaged. It is difficult for the bolts to have an anti-loosening function to achieve a long-term reliable connection. When connecting two parts with bolts, they need to be tightened several times and then tightened with tools such as wrenches. If the number of turns of manual tightening of the bolt can be increased and the number of turns of tightening using tools can be reduced, the work efficiency can be improved. Therefore, a bolt with an anti-loosening function is proposed to solve the above problem. Utility Model Content

[0003] The disclosed embodiment relates to a bolt with an anti-loosening function. When the inner rod is pulled, the push rod is driven to open and close. The retaining ring slides on the outside of the opening and closing rod, pushing the opening and closing rod to change its angle until the ranging probe rests against the inner wall of the telescopic shell and fits tightly against the inner wall of the hole formed by the squeezed branch pile to perform aperture detection.

[0004] In a first aspect of the present disclosure, a bolt with an anti-loosening function is provided, specifically comprising: a bolt body; the outer wall of the bolt body is provided with a thread, and is matched with an external hexagonal nut to be connected to the inside of the threaded holes of two workpieces to be connected, the external thread of the bolt body is connected to a washer, and the top of the bolt body is integrally formed with a bolt head; two anti-loosening blocks are clamped inside the bolt head; the anti-loosening blocks are clamped on the washer.

[0005] In at least some embodiments, an inner groove is provided inside the bolt head, and a circular rotating groove is provided at the outer end of the inner groove. When the anti-loosening block is slidably engaged inside the inner groove, it can move in a directional manner. If a rectangular groove is provided at the external connection, it can be inserted into the rectangular groove to achieve anti-loosening limitation for the bolt body.

[0006] In at least some embodiments, external clamping blocks are welded on both sides of the outside of the anti-loosening block, and the external clamping blocks are slidably clamped in the inner sliding groove, and the oblique length of the external clamping block is smaller than the inner diameter of the rotating groove. An internal clamping groove is provided inside the anti-loosening block, and the width of the internal clamping groove matches the limiting clamping block. When the anti-loosening block is in a horizontal state, the outer end of the anti-loosening block is a sloped structure. When the anti-loosening block is in a vertical state, the inner clamping groove is clamped on the outside of the limiting block, and the outer end surface of the anti-loosening block is in contact with the top surface of the gasket.

[0007] In at least some embodiments, a gasket ring is welded to the top surface of the gasket, a limiting block is integrally formed on the outer wall of the gasket ring, a thread is provided on the inner wall of the gasket and is connected to the bolt body, and six limiting blocks are evenly spaced.

[0008] The utility model provides a bolt with an anti-loosening function, which has the following beneficial effects:

[0009] When the utility model is in use, after completing the connection between the bolt body and the two workpieces, the anti-loosening block is pulled out, and after the outer block is located inside the rotation groove, the anti-loosening block is rotated to clamp it onto the limit block, so that the bolt body and the washer cannot rotate relative to each other, thereby achieving the anti-loosening function.

[0010] In addition, when the anti-loosening block is slidably engaged inside the inner slide groove, it can move in a directional manner. If a rectangular groove is provided at the external connection, it can be inserted into the rectangular groove to prevent the bolt body from loosening. It can also be used as an auxiliary rod to increase the force arm, thereby improving the tightening degree of manual tightening, reducing the number of turns using a wrench, and improving the efficiency of assembling or connecting workpieces.

[0025] The utility model proposes a bolt with an anti-loosening function, comprising: a bolt body 1; a thread is provided on the outer wall of the bolt body 1, and is connected to the inside of threaded holes of two workpieces to be connected in conjunction with an external hexagonal nut; a washer 2 is connected to the outer thread of the bolt body 1, and a bolt head 101 is integrally formed on the top of the bolt body 1; two anti-loosening blocks 3 are clamped inside the bolt head 101; the anti-loosening blocks 3 are clamped on the washer 2.

[0026] In the embodiment of the present disclosure, as shown in the attached Figure 1 and attached Figure 3 As shown, an inner groove 1011 is provided inside the bolt head 101, and a rotating groove 1012 with a circular structure is provided at the outer end of the inner groove 1011. When the anti-loosening block 3 is slidably connected to the inner groove 1011, it can be moved in a directional manner. If a rectangular groove is provided at the external connection, it can be inserted into the rectangular groove to prevent the bolt body 1 from loosening. It can also be used as an auxiliary rod to increase the force arm, thereby improving the tightening degree of manual screwing.

[0027] In the embodiment of the present disclosure, as shown in the attached Figure 4 and attached Figure 5When the bolt 1 is in the upright position, the cam 302 is in the upright position, and the cam 303 is in the upright position, so that the cam 303 can be locked in the upright position without being locked.

[0028] In the embodiment of the present disclosure, as shown in the attached Figure 5 As shown, a washer 201 is welded to the top surface of the washer 2, and a limiting block 2011 is integrally formed on the outer wall of the washer 2. A thread is provided on the inner wall of the washer 2 and is connected to the bolt body 1. There are six limiting blocks 2011 distributed at equal intervals. The washer 2 and the washer 201 can protect the joint between the bolt head 101 and the connected workpiece, thereby improving the connection tightening strength.

[0029] In the second embodiment, based on the first embodiment, there are six limit blocks 2011 distributed at equal intervals, but the number is not limited to six. When used for a relatively delicate bolt body 1, the number can be set to twelve or more to meet the use requirements.

[0031] In the present invention, the bolt body 1 is passed through the threaded holes of the two workpieces to be connected, the anti-loosening block 3 is pulled out to increase the force arm, and the hexagonal nut is screwed to tighten the connection. After the tightening connection is completed, the anti-loosening block 3 is rotated ninety degrees and clamped to the limit block 2011. The bolt body 1 and the washer 2 cannot rotate relative to each other, thereby achieving an anti-loosening effect.
