Description

Technical Field

[0001] This utility model belongs to the field of fastening technology, specifically a high-performance fastener port connection structure. Background Technology

[0002] Fasteners are a widely used type of component in mechanical engineering, mainly used to fasten two or more parts together into a whole.

[0003] Bolts and nuts are among the most widely used fasteners in mechanical engineering. They are mainly used to fasten two parts with through holes. The friction between the threads on the outer surface of the bolt and the inner surface of the nut makes it difficult for the relative position between the bolt and the nut to change, thereby fixing and limiting the fastened parts. However, during long-term use, the threads on the bolt are easily damaged, making it difficult to turn the nut when disassembling it, thus making it difficult to remove and affecting the release of the fastener's restriction.

[0004] Therefore, this utility model provides a high-performance fastener port connection structure. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The high-performance fastener port connection structure of this utility model includes a pair of half-screw sleeves, a connecting shaft rotatably connected to the middle of the pair of half-screw sleeves, a threaded groove in the middle of one half-screw sleeve, and a connecting groove in the middle of the other half-screw sleeve. A connecting bolt is slidably installed in the middle of the connecting groove. The connecting bolt and the threaded groove are threadedly engaged. With the above structure, when the thread of the bolt is affected, making it difficult for the half-screw sleeves to rotate normally and remove, the pair of half-screw sleeves can be easily separated and removed to relieve the restriction on the fastener.

[0007] Preferably, each of the pair of semi-screw sleeves has a slot in the middle, and an I-beam can be detachably installed in the middle of the pair of slots. With the above structure, the occurrence of gaps due to deformation under stress at the connection between the pair of semi-screw sleeves can be reduced, thus reducing the occurrence of a decrease in the fastening effect.

[0008] Preferably, the I-beam has multiple through holes in its middle section, and a pry bar is fixed to the side wall of a pair of semi-screw sleeves. With the above structure, the ease of operation can be improved when removing the I-beam, and the inconvenience caused by excessive friction between the I-beam and the slot can be reduced.

[0009] Preferably, a sealing plug is installed in the middle of the connecting groove by means of a thread, and a lever is fixed to the side wall of the sealing plug. Through the above structure, external moisture can be isolated, reducing the occurrence of inconvenience in removal due to corrosion of the connecting bolts.

[0010] Preferably, the dial plate has a through groove in the middle and is made of a hard material. With the above structure, when the component size is small, the dial plate can be installed and removed using hook-like tools, which makes the dial plate more airtight after installation or easier to remove.

[0011] Preferably, a gasket is detachably installed in the middle of the connecting groove. The gasket has a certain elasticity. Through the above structure, the influence of vibration on the connecting bolt can be reduced, and the occurrence of a decrease in the fastening effect caused by the loose connection of the two half threaded sleeves due to vibration rotation of the connecting bolt can be reduced.

[0012] Preferably, the connecting shaft is made of titanium alloy, which has high hardness. The above structure can reduce the occurrence of the problem that the pair of threaded sleeves cannot rotate relative to each other due to deformation of the connecting shaft under stress.

[0013] The beneficial effects of this utility model are:

[0014] 1. The high-performance fastener port connection structure described in this utility model, through the arrangement of a half-screw sleeve, a connecting shaft, a threaded groove, a connecting groove, and a connecting bolt, allows for convenient separation and removal of a pair of half-screw sleeves when the bolt thread is affected, making it difficult for the half-screw sleeves to rotate normally and remove them, thus relieving the restriction on the fastener.

[0015] 2. The high-performance fastener port connection structure described in this utility model, through the setting of slots and I-beams, can reduce the occurrence of gaps caused by stress deformation at part of the connection between a pair of half-threaded sleeves, which leads to a decrease in the fastening effect.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 4 As shown, a high-performance fastener port connection structure according to an embodiment of this utility model includes a pair of half-screw sleeves 1. A connecting shaft 12 is rotatably connected to the middle of the pair of half-screw sleeves 1. A threaded groove 13 is formed in the middle of one half-screw sleeve 1, and a connecting groove 14 is formed in the middle of the other half-screw sleeve 1. A connecting bolt 15 is slidably installed in the middle of the connecting groove 14. The connecting bolt 15 and the threaded groove 13 are threadedly engaged. In operation, the pair of half-screw sleeves 1 are fitted onto the middle of the connecting bolt, and then the connecting bolt 15 is inserted into the inside of the connecting groove 14 and rotated so that the end of the connecting bolt 15 is threadedly engaged. Inside the threaded groove 13, through the continuous rotation of the connecting bolt 15, a pair of half-threaded sleeves 1 will approach each other and be tightly connected together. When it is necessary to disassemble the half-threaded sleeves 1 but the half-threaded sleeves 1 and the bolt are difficult to rotate and remove due to the influence of foreign objects, the connecting bolt 15 can be rotated to remove them, so that the pair of half-threaded sleeves 1 can be rotated and separated. This allows the pair of half-threaded sleeves 1 to be easily removed from the middle of the bolt, thus removing the restriction on the fastener. Through the above structure, when the bolt thread is affected, making it difficult for the half-threaded sleeves 1 to rotate and remove normally, the pair of half-threaded sleeves 1 can be easily separated and removed, thus removing the restriction on the fastener.

[0024] like Figures 1 to 4 As shown, each of the two half-threaded sleeves 1 has a slot 2 in the middle. An I-beam 21 is detachably installed in the middle of the two slots 2. During operation, after the two half-threaded sleeves 1 are closed and fitted onto the bolt, the two slots 2 are connected to form an I-beam groove. Then, the I-beam 21 is inserted into the two slots 2. This increases the connection force between the two half-threaded sleeves 1 when the closed half-threaded sleeves 1 are rotated to tighten the fastener. It also reduces the possibility of the two half-threaded sleeves 1 being deformed by the tool and separating at the two slots 2, which could lead to failure of the thread fit between the two half-threaded sleeves 1 and the bolt. Through the above structure, the occurrence of gaps due to deformation at the connection between the two half-threaded sleeves 1 can be reduced, thus reducing the possibility of a decrease in the tightening effect.

[0025] like Figures 1 to 4As shown, the H-beam 21 has multiple through holes 3 in its middle. A pair of half-threaded sleeves 1 are fixed to the side walls of a pry bar 31. When the pair of half-threaded sleeves 1 are used to press and tighten the object being fastened, the friction between the pair of slots 2 and the H-beam 21 will increase. Therefore, when it is necessary to disassemble the half-threaded sleeves 1, it is difficult to easily remove the H-beam 21. At this time, a pry bar can be inserted into the through hole 3 and the middle of the pry bar can be placed on the pry bar 31. The lever principle can be used to gradually pry out the H-beam 21. During this process, the multiple through holes 3 on the H-beam 21 will gradually leak out from the slot 2. Then, the pry bar can be inserted into different through holes 3 in sequence and the lever principle can be used to pry the H-beam 21 out of the slot 2. Through the above structure, the operation convenience can be improved when removing the H-beam 21, and the situation of inconvenience caused by excessive friction between the H-beam 21 and the slot 2 can be reduced.

[0026] like Figures 1 to 2 As shown, a sealing plug 4 is installed in the middle of the connecting groove 14 by means of threaded engagement. A lever plate 41 is fixed to the side wall of the sealing plug 4. During operation, after connecting a pair of half-threaded sleeves 1 with the connecting bolt 15, the lever plate 41 is pinched to rotate the sealing plug 4 into the connecting groove 14. The sealing plug 4 isolates external moisture and reduces the occurrence of inconvenience caused by corrosion of the connecting bolt 15.

[0027] like Figure 2 As shown, a through groove 5 is provided in the middle of the lever plate 41. The lever plate 41 is made of a hard material. When the component size is small, a hook can be inserted into the through groove 5 to hook the lever plate 41, so that the lever plate 41 can be easily adjusted. With the above structure, when the component size is small, hook-like tools can be used to install and remove the lever plate 41, so that the sealing performance of the lever plate 41 is better after installation, or it is easier to remove.

[0028] like Figure 2 As shown, a gasket 6 is detachably installed in the middle of the connecting groove 14. The gasket 6 has a certain elasticity. Through the above structure, the influence of vibration on the connecting bolt 15 can be reduced, and the occurrence of a decrease in the fastening effect caused by the loose connection of the pair of half threaded sleeves 1 due to vibration rotation of the connecting bolt 15 can be reduced.

[0029] like Figure 1 As shown, the connecting shaft 12 is made of titanium alloy, which has high hardness. Through the above structure, the situation where the pair of half-threaded sleeves 1 are difficult to rotate relative to each other due to the deformation of the connecting shaft 12 under stress can be reduced.

[0030] During operation, a pair of half-threaded sleeves 1 are fitted onto the middle of the connecting bolt. Then, the connecting bolt 15 is inserted into the connecting groove 14 and rotated, causing the end of the connecting bolt 15 to be threaded into the threaded groove 13. Through continuous rotation of the connecting bolt 15, the pair of half-threaded sleeves 1 will approach each other and connect tightly. When it is necessary to disassemble the half-threaded sleeves 1 but they are difficult to remove from the bolt due to external interference, the connecting bolt 15 can be rotated to remove them, allowing the pair of half-threaded sleeves 1 to rotate and separate. This facilitates the removal of the pair of half-threaded sleeves 1 from the middle of the bolt, releasing the restriction on the fastened component. After the pair of half-threaded sleeves 1 are closed and fitted onto the bolt, a pair of slots 2 are connected to form an I-beam groove. Then, an I-beam 21 is inserted into the pair of slots 2. This increases the connection strength between the pair of half-threaded sleeves 1 when the closed pair of half-threaded sleeves 1 are rotated to tighten the fastened component, reducing deformation of the pair of half-threaded sleeves 1 due to tool pressure and preventing damage to the slots 2. Separation leads to failure of the threaded fit between the pair of half-threaded sleeves 1 and the bolt. When the pair of half-threaded sleeves 1 are pressed and tightened on the fastened object, the friction between the pair of slots 2 and the I-beam 21 will increase, making it difficult to remove the I-beam 21 when the half-threaded sleeves 1 need to be disassembled. At this time, a pry bar can be inserted into the through hole 3 and the middle of the pry bar can be placed on the pry base 31. The I-beam 21 can be pried out gradually using the lever principle. During this process, multiple through holes 3 on the I-beam 21 will gradually leak out from the slot 2. Then, the pry bar can be inserted into different through holes 3 in sequence and the I-beam 21 can be pried out of the slot 2 by using the lever principle. After connecting the pair of half-threaded sleeves 1 with the connecting bolt 15, the sealing plug 4 is rotated and installed into the connecting groove 14 by pinching the lever 41. The sealing plug 4 isolates external moisture. When the component size is small, a hook can be inserted into the through groove 5 to hook the lever 41, so that the lever 41 can be adjusted easily.

[0031] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
