Description

Technical Field

[0001] The utility model relates to the technical field of nuts, in particular to a one-way anti-disassembly hexagonal nut. Background Art

[0002] Nuts are parts that are screwed together with bolts or screws to fasten them together. Nuts are parts that tightly connect mechanical equipment. Nuts and bolts of the same specifications can only be connected together through the inner threads.

[0003] The nuts on the market today have relatively simple functions. After the nuts are used to fix valuable equipment, they are difficult to disassemble, which makes them unable to prevent theft for the fixed equipment. In response to the above situation, technical innovation is carried out based on the existing nuts. Utility Model Content

[0004] The purpose of the utility model is to provide a one-way anti-disassembly hexagonal nut to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a one-way anti-disassembly hexagonal nut, comprising:

[0006] A hexagonal block, wherein a through hole is provided on the top of the hexagonal block, an annular groove is provided on the inner wall of the through hole, a one-way bearing is provided in the annular groove, a group of sealing rings are provided on the upper and lower sides of the one-way bearing, a thread is provided on the inner side wall of the one-way bearing, and two groups of identification grooves are evenly provided on the top of the hexagonal block.

[0007] Preferably, the outer side wall of the outer ring of the one-way bearing and the inner side wall of the annular groove of the hexagonal block are fixedly connected.

[0008] Preferably, the upper and lower sides of the outer ring of the one-way bearing are fixedly connected to the upper and lower sides of the inner sidewall of the annular groove of the hexagonal block.

[0009] Preferably, the height of the inner ring of the one-way bearing is lower than the height of the outer ring of the one-way bearing.

[0010] Preferably, the height of the inner ring of the one-way bearing and the total height of the two sets of sealing rings are the same as the height of the outer ring of the one-way bearing.

[0011] Preferably, the inner ring of the one-way bearing is rotatably arranged in the annular groove of the hexagonal block, and the opposite sides of the two groups of sealing rings are tightly fitted with the upper and lower sides of the inner side walls of the annular groove of the hexagonal block respectively.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model forms a one-way rotating nut by the mutual cooperation of the hexagonal block and the one-way bearing, which benefits from the counterclockwise one-way rotation of the one-way bearing. When the one-way rotating nut is disassembled, the counterclockwise rotation of the hexagonal block will drive the outer ring of the one-way bearing to rotate, but will not drive the inner ring of the one-way bearing to rotate, thereby achieving the counterclockwise non-removable effect of the one-way rotating nut.

[0014] The connecting gap between the inner ring of the one-way bearing and the annular groove of the hexagonal block is sealed by a sealing ring to prevent external contaminants from affecting the one-way rotating structure inside the one-way bearing, thereby ensuring the reliability of the one-way anti-disassembly device.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 3A one-way anti-disassembly hexagonal nut includes a hexagonal block 1, a through hole is opened on the top of the hexagonal block 1, an annular groove is opened on the inner wall of the through hole, and a one-way bearing 12 is fixedly arranged in the annular groove. The one-way bearing 12 is a more common mechanical accessory nowadays. Its working principle is now more mature. I will not go into details here. The outer ring of the one-way bearing 12 only supports one-way rotation. A set of sealing rings 11 are fixedly arranged on the upper and lower sides of the one-way bearing 12. The inner wall of the one-way bearing 12 is threaded. The top of the hexagonal block 1 is evenly opened. There are two groups of identification grooves 13, through which the counterclockwise rotation direction of the one-way bearing 12 is marked. The hexagonal block 1 and the one-way bearing 12 cooperate with each other to form a one-way rotating nut. When the one-way rotating nut is screwed clockwise with the external bolt using the thread opened on the inner wall of the one-way bearing 12, since the one-way bearing 12 can only rotate counterclockwise, when the hexagonal block 1 rotates clockwise, it can drive the one-way bearing 12 to rotate clockwise, thereby realizing the clockwise screw connection with the bolt. When the one-way rotating nut is disassembled, As the hexagonal block 1 rotates counterclockwise, the outer ring of the one-way bearing 12 will be driven to rotate, but the inner ring of the one-way bearing 12 will not be driven to rotate, thereby achieving the counterclockwise non-removable effect of the one-way rotating nut. The outer wall of the outer ring of the one-way bearing 12 is fixedly connected to the inner wall of the annular groove of the hexagonal block 1. The upper and lower sides of the outer ring of the one-way bearing 12 are fixedly connected to the upper and lower sides of the inner wall of the annular groove of the hexagonal block 1. The height of the inner ring of the one-way bearing 12 is lower than the height of the outer ring of the one-way bearing 12. The inner ring of the one-way bearing 12 The ring height and the total height of the two sets of sealing rings 11 are the same as the outer ring height of the one-way bearing 12. The inner ring of the one-way bearing 12 is rotatably arranged in the annular groove of the hexagonal block 1. The opposite sides of the two sets of sealing rings 11 are tightly fitted with the upper and lower sides of the inner side walls of the annular groove of the hexagonal block 1 respectively. The connecting gap between the inner ring of the one-way bearing 12 and the annular groove of the hexagonal block 1 is sealed by the sealing ring 11 to prevent external contaminants from affecting the one-way rotating structure inside the one-way bearing 12, thereby ensuring the reliability of the one-way anti-disassembly device.

[0021] Working principle: The counterclockwise rotation direction of the one-way bearing 12 is marked by the identification groove 13, and the one-way bearing 12 cooperates with each other to form a one-way rotating nut. When the one-way rotating nut is screwed clockwise with the external bolt using the thread opened on the inner wall of the one-way bearing 12, since the one-way bearing 12 can only rotate counterclockwise, when the hexagonal block 1 rotates clockwise, it can drive the one-way bearing 12 to rotate clockwise, thereby realizing the clockwise screw connection with the bolt. When the one-way rotating nut is disassembled, as the hexagonal block 1 rotates counterclockwise, the outer ring of the one-way bearing 12 will be driven to rotate, but the inner ring of the one-way bearing 12 will not be driven to rotate, thereby achieving the counterclockwise non-removable effect of the one-way rotating nut, and the connecting gap between the inner ring of the one-way bearing 12 and the annular groove of the hexagonal block 1 is sealed by the sealing ring 11 to prevent external contaminants from affecting the one-way rotating structure inside the one-way bearing 12, thereby ensuring the reliability of the one-way anti-disassembly device.
