Description

Technical Field

[0001] This utility model relates to the field of octagonal cap technology, specifically to an octagonal cap mounted on a stainless steel valve body. Background Technology

[0002] For four-corner nuts, rotating them 90° will cause the four corners to align. For hexagonal nuts, only a 60° rotation is needed for the hexagonal heads to align, allowing for further tightening with a wrench, suitable for tightening nuts in confined spaces. While a standard octagonal nut has a 45° rotation angle for alignment, its small octagonal shape makes it prone to slipping when tightening with a wrench. Utility Model Content

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an octagonal cap for mounting stainless steel valve bodies, which solves the problem that the existing octagonal outer edge dimensions are too small and easily slip when tightening with a wrench.

[0004] (II) Technical Solution To achieve the above, this utility model provides the following technical solution: an octagonal cap for mounting on a stainless steel valve body, comprising a base: The base has an octagonal cap on top, and the octagonal cap has a threaded groove inside; The inner wall of the threaded groove is provided with a sealing strip; An arc plate is provided between the threaded grooves; The outer wall of the octagonal cap has a groove; The groove is equipped with a retaining post; The octagonal cap has eight sides, and each side has a limiting post on both sides of its outer surface, which can effectively stabilize the octagonal cap and prevent it from becoming loose.

[0005] Optionally, the sealing strip may be made of rubber or other soft materials, and the shape of the sealing strip is consistent with the shape of the threaded groove, which can effectively achieve the sealing between the octagonal cap and its mating parts, and avoid the phenomenon of gaps between them that could lead to loosening.

[0006] Optionally, the arc plate can be made of rubber or other soft materials. The top of the arc plate is semi-circular, and the arc plate is tilted downward at 30 degrees. This can effectively achieve the stability between the octagonal cap and its mating parts, increase the friction between them, and make the connection between them tighter.

[0007] Optionally, the locking post includes: A fixed shaft is installed at the bottom inner side of the groove; A pivot is mounted on the top inner side of the groove; A rotating drum, which is mounted on a fixed shaft; Bearings, which are mounted on a rotating shaft; The movable shaft is installed at the bottom of the bearing, and the bottom of the movable shaft is connected to the top of the rotating drum. This effectively achieves stability between the shaft and the wrench, preventing slippage between the wrench and the octagonal cap when the wrench is engaged and rotated.

[0008] Optionally, the outer walls of the rotating shaft, rotating cylinder, and movable shaft are all surrounded by protrusions. The protrusions are rectangular in shape, which can effectively achieve stability with the inside of the wrench, so that friction is formed between the two and the slippage is avoided when the two come into contact.

[0009] Optionally, the limiting post is composed of a connecting shaft, a ratchet, and a limiting groove. The ratchet is connected through the connecting shaft and is rotatable. This effectively stabilizes the two sides inside the wrench, creating friction between them and the two sides inside the wrench, thus generating resistance and further preventing slippage when they come into contact.

[0010] Optionally, the outer wall of the ratchet is surrounded by protrusions, which are rectangular in shape, and a limiting groove is provided between the protrusions to effectively buffer the resistance generated when in contact with the inner sides of the wrench, thus preventing damage to the ratchet.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides an octagonal cap for mounting on a stainless steel valve body, which has the following advantages: 1. When the wrench is screwed in using the locking post and octagonal cap, it engages with the surface of the locking post through the opening of the wrench. At this time, the locking post is in contact with the inside of the wrench, and the inside of the hand is in contact with the outer wall of the locking post. At this time, the protrusions on the outer walls of the rotating shaft, rotating cylinder, and movable shaft are in contact with the inside of the wrench. The protrusions can further increase the friction between the wrench and the wrench. At the same time, when the wrench is in contact with the locking post, the rotating shaft, rotating cylinder, and movable shaft also rotate with each rotation of the wrench, thereby further preventing the wrench from slipping. 2. This utility model uses a limiting post. When the wrench is screwed into the octagonal cap, the two inner sides of the wrench are in contact with the limiting post. The ratchet also contacts the two inner sides of the wrench, further stabilizing the wrench. The protrusions on the outer wall of the ratchet further increase the friction between the ratchet and the two inner sides of the wrench, thus creating resistance and preventing slippage. The limiting groove between the protrusions effectively buffers the resistance generated when in contact with the two inner sides of the wrench, preventing damage to the ratchet. 3. This utility model utilizes a sealing strip and an arc plate. When the octagonal cap mates with its mating part, the mating part is embedded inside the octagonal cap. The octagonal cap is screwed into the mating part through a threaded groove. The sealing strip and the threaded groove embedded in the mating part create a sealed space between the octagonal cap and the mating part, filling the gap and preventing loosening. When the octagonal cap is screwed into the mating part, the arc plate contacts the inner wall of the mating part. The 30-degree inclined, rubber-made arc plate effectively creates friction with the inner wall of the mating part, further enhancing the tightness between the octagonal cap and the mating part and further preventing loosening.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Please refer to Figures 1 to 3The present invention provides a technical solution: an octagonal cap for mounting on a stainless steel valve body, comprising a base 1. The base 1 has an octagonal cap 2 on its top, and the octagonal cap 2 has a threaded groove 201 inside. A sealing strip 202 is provided on the inner wall of the threaded groove 201; An arc plate 203 is provided between the threaded grooves 201; The outer wall of the octagonal cap 2 has a groove 204; The groove 204 has a retaining post 3 inside; The octagonal cap 2 has eight sides, and each side has a limiting post 4 on both sides of its outer surface. When the octagonal cap 2 is installed, the symmetrical eight sides of the octagonal cap 2 can effectively increase the stability between the octagonal cap 2 and the mating parts, and prevent it from becoming loose.

[0016] Based on the above embodiments, in this embodiment, the sealing strip 202 can be made of rubber or other soft materials. The shape of the sealing strip 202 is consistent with the shape of the threaded groove 201. When the octagonal cap 2 is engaged with its mating part, the mating part is embedded inside the octagonal cap 2. The octagonal cap 2 is screwed into the mating part through the threaded groove 201. At this time, the sealing strip 202 and the threaded groove embedded in the mating part form a sealed space between the octagonal cap 2 and the mating part. The sealing strip 202 can fill the gap between the two and prevent the two from becoming loose.

[0017] Based on the above embodiments, in this embodiment, the arc plate 203 can be made of rubber or other soft materials. The top of the arc plate 203 is semi-circular, and the arc plate 203 is inclined downward at 30 degrees. When the octagonal cap 2 is screwed into the interior of the mating part, the arc plate 203 contacts the inner wall of the mating part. The arc plate 203, which is inclined at 30 degrees and is made of rubber, can effectively form friction with the inner wall of the mating part, thereby further achieving the fastening between the octagonal cap 2 and the mating part, and further preventing the phenomenon of loosening between the two.

[0018] Based on the above embodiments, the locking post 3 in this embodiment includes: A fixed shaft 301 is installed at the bottom inner side of the groove 204; The rotating shaft 302 is mounted on the top inner side of the groove 204; Rotary drum 303 is mounted on fixed shaft 301; Bearing 304 is mounted on rotating shaft 302; The movable shaft 305 is installed at the bottom of the bearing 304, and the bottom of the movable shaft 305 is connected to the top of the rotating drum 303. When the wrench is screwed into the octagonal cap 2, it is engaged with the surface of the retaining post 3 through the opening of the wrench. At this time, the retaining post 3 is in contact with the inside of the wrench. When the two are in contact, the retaining post 3 will generate a force on the inside of the wrench. The force generated can limit the wrench, thereby increasing the friction between the two and preventing the wrench from slipping when screwing into the octagonal cap 2.

[0019] Based on the above embodiments, in this embodiment, the outer walls of the rotating shaft 302, rotating cylinder 303, and movable shaft 305 are all surrounded by protrusions, which are rectangular in shape. When the inside of the wrench contacts the outer wall of the locking post 3, the protrusions on the outer walls of the rotating shaft 302, rotating cylinder 303, and movable shaft 305 also contact the inside of the wrench. The protrusions can further increase the friction between the wrench and the wrench. At the same time, when the wrench contacts the locking post 3, the rotating shaft 302, rotating cylinder 303, and movable shaft 305 also rotate with each rotation of the wrench, thereby further preventing the wrench from slipping.

[0020] Based on the above embodiments, in this embodiment, the limiting post 4 is composed of a connecting shaft 401, a ratchet 402, and a limiting groove 403. The ratchet 402 is connected through the connecting shaft 401 and is rotatable. The outer wall of the ratchet 402 is surrounded by a rectangular protrusion, and the limiting groove 403 is provided between the protrusions. When the wrench is screwed into the octagonal cap 2, the two inner sides of the wrench are in contact with the limiting post 4. The contact between the ratchet 402 and the two inner sides of the wrench can further achieve a stabilizing effect on the two sides of the wrench. The protrusion on the outer wall of the ratchet 402 can further increase the friction between the two inner sides of the wrench, thereby forming resistance on the two inner sides of the wrench and further preventing slippage when they are in contact. The limiting groove 403 between the protrusions can effectively buffer the resistance generated when in contact with the two inner sides of the wrench and prevent damage to the ratchet 402.
