[0002] Aviation plug is a type of connector, originated from the military industry. The shell of the aviation plug plays a role in protecting the aviation plug body. The shell can reduce the damage caused by the internal plug body, thereby effectively extending the service life of the aviation plug body.

[0003] In the prior art, the Chinese patent with the authorization announcement number CN216214369U discloses an aviation head structure with stable connection, which aims to solve the technical problems that the aviation head connection structure in the prior art cannot be disassembled when it needs to be repaired and disassembled, and there is no corresponding anti-impact protection structure and insufficient plug-in stability when it is used. The aviation head structure includes an aviation joint body, a mounting sleeve module installed on the aviation joint body, a connecting sleeve module connected to the aviation joint body for mating connection, a threaded sleeve assembly connected to the connecting sleeve module for threaded connection, an insertion assembly arranged inside the connecting sleeve module for enabling insertion connection, and a protective outer ring assembly arranged outside the insertion assembly for connection protection. The aviation head structure can facilitate disassembly and assembly through the threaded sleeve assembly when it needs to be disassembled and repaired, and can achieve elastic locking effect by using the insertion assembly.

[0004] The above-mentioned mechanism can achieve the effect of easy disassembly and assembly by utilizing the threaded sleeve assembly, so that the aviation head can be easily disassembled for maintenance. However, in actual use, the outer shell of the aviation head is prone to broken columns in unconventional usage scenarios, causing the product to twist and break, affecting the stable use of the aviation head. Utility Model Content

[0005] The purpose of the utility model is to provide an aviation head shell with strong anti-twisting ability, so as to solve the problem that the aviation head shell mentioned in the above background technology is prone to broken columns in unconventional usage scenarios.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aviation head shell with strong anti-twisting ability, comprising an aviation head shell body and a threaded groove arranged on the outer side of the aviation head shell body, a clamping block is fixedly connected to the top of the aviation head shell body, and a PCB board is clamped and connected to the outer side of the clamping block;

[0007] The PCB board is arranged above the aviation head shell body, and an anti-twisting mechanism is arranged inside the PCB board to increase the anti-tilting and anti-twisting capabilities of the aviation head shell body and the PCB board, and the anti-twisting mechanism includes a partition plate, and the partition plate is fixedly connected to the inside of the PCB board;

[0008] A fixing groove is provided on one side of the PCB board, and a fixing block matching the fixing groove is fixedly connected to the top of the aviation head shell body, and a sealing mechanism for increasing the fit strength is provided on one side between the fixing groove and the fixing block.

[0009] Furthermore, a reinforcing rib is provided on one side between the partition plates, and an auxiliary rod is fixedly connected inside the reinforcing rib.

[0010] Furthermore, the cross section of the auxiliary rod is triangular, and the length of the auxiliary rod is equal to the length of the reinforcing rib.

[0011] Furthermore, the sealing mechanism includes a pressing block, and the pressing block is fixedly connected to the upper end of one side of the fixing block, a first airbag is arranged on the inner side of the fixing groove below the pressing block, and the bottom end of the first airbag is fixedly connected to the second airbag through a hose.

[0012] Furthermore, the second airbag is fixedly connected to one side between the fixing groove and the fixing block, and a sealing layer is provided on the inner side of the second airbag.

[0013] Furthermore, the cross section of the sealing layer is in a "C" shape, and the inner side of the sealing layer fits with the outer side of the fixing block.

[0014] Furthermore, the top of the card block passes through the card slot and extends above the PCB board, and the card block and the fixed block are on the same central axis:

[0015] 1. The overall appearance of the aviation head shell body is changed to a flat one, which increases the anti-twisting ability of the aviation head shell body. At the same time, the PCB board can limit the position of the PCB board through the engagement between the card block and the card slot, thereby achieving the fixation of the PCB board position. The anti-twisting mechanism inside the PCB board can increase the anti-twisting ability of the PCB board itself, thereby increasing the anti-twisting ability of the aviation head shell body itself during use. At the same time, the increase in anti-twisting force can also effectively avoid the break between the PCB board and the card block;

[0016] Furthermore, the anti-distortion mechanism inside the PCB divides and reinforces the interior of the PCB through the partition plate, so that the force required for bending the PCB is increased, and the space between the partition plates is used to increase the reinforcing ribs and auxiliary rods. The shape of the auxiliary rods can increase the anti-distortion ability inside the reinforcing ribs, effectively avoiding the problem of the partition plates being damaged due to the bending of the reinforcing ribs. At the same time, the reinforcing ribs can fill the divided space, thereby increasing the overall anti-distortion ability of the PCB.

[0017] Furthermore, an anti-tilting and anti-twisting fixing block is added to the bottom of the flange outside the aviation head shell body. The fixing block and the PCB board are fitted with high strength through the fixing groove to increase the torsion of the product. The position of the PCB board can be restricted twice through the fixing groove and the fixing block. At the same time, the PCB board and the flat surface of the aviation head shell body are more closely fitted, and the overall anti-twisting performance is increased through high-strength fit.

[0018] 2. When the PCB board is fitted between the fixing groove and the fixing block to increase the anti-twisting ability, the pressing block at one end of the fixing block will press the first airbag, so that the gas inside the first airbag is transported to the inside of the second airbag through the hose, so that the second airbag expands, thereby effectively preventing the fixing groove and the fixing block from loosening after being engaged;

[0019] Furthermore, the sealing layer fits with the outer side of the fixing block, so that the gap between the fixing groove and the fixing block is reduced, so that the fixing groove and the fixing block can be clamped more tightly, and the fixing groove and the fixing block fit firmly, effectively increasing the anti-twisting force of the PCB board when in use.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] like Figure 1-6 The technical solution shown is to solve the problem that the aviation head shell is prone to broken columns in unconventional usage scenarios: the aviation head shell with strong anti-twisting ability discloses an anti-twisting mechanism, including an aviation head shell body 1 and a threaded groove 2 arranged on the outside of the aviation head shell body 1, the top of the aviation head shell body 1 is fixedly connected with a card block 4, and the outside of the card block 4 is snap-connected with a PCB board 3, the PCB board 3 is arranged above the aviation head shell body 1, and the inside of the PCB board 3 is provided with an anti-twisting mechanism for increasing the anti-tilting and anti-twisting capabilities of the aviation head shell body 1 and the PCB board 3, the anti-twisting mechanism includes a partition plate 13, and the partition plate 13 is fixedly connected to the inside of the PCB board 3, a reinforcing rib 14 is arranged on one side between the partition plates 13, and an auxiliary rod 15 is fixedly connected to the inside of the reinforcing rib 14, the cross-section of the auxiliary rod 15 is triangular, and the length of the auxiliary rod 15 is equal to the length of the reinforcing rib 14.

[0031] In this example, the overall appearance of the aviation head shell body 1 is changed to be flat to increase the anti-twisting ability of the aviation head shell body 1. At the same time, the PCB board 3 can limit the position of the PCB board 3 through the engagement between the block 4 and the slot 5, thereby realizing the fixation of the position of the PCB board 3, and the anti-twisting mechanism inside the PCB board 3 can increase the anti-twisting ability of the PCB board 3 itself, so that the anti-twisting ability of the aviation head shell body 1 itself during use can also be increased. At the same time, after the anti-twisting force is increased, the fracture between the PCB board 3 and the block 4 can be effectively avoided. The anti-twisting mechanism inside the PCB board 3 divides and reinforces the interior of the PCB board 3 through the partition plate 13, so that the force required for the PCB board 3 to be bent is increased, and the space between the partition plates 13 is used to increase the reinforcing ribs 14 and the auxiliary rods 15. The shape of the auxiliary rods 15 can increase the anti-twisting ability inside the reinforcing ribs 14, effectively avoiding the problem of damage to the partition plate 13 caused by the bending of the reinforcing ribs 14. At the same time, the reinforcing ribs 14 can fill the divided space, thereby increasing the overall anti-twisting ability of the PCB board 3.

[0032] Embodiment 2:

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The technical solution shown is based on embodiment 1, in order to solve the problem that the PCB board 3 is easily displaced and causes distortion and the block 4 is broken during use: the aviation head shell with strong anti-twisting ability discloses a limiting mechanism, a fixing groove 6 is opened on one side of the PCB board 3, and the top of the aviation head shell body 1 is fixedly connected with a fixing block 7 matching the fixing groove 6, the top of the block 4 passes through the slot 5 and extends to the top of the PCB board 3, and the block 4 and the fixing block 7 are on the same central axis.

[0034] In this example, an anti-tilting and anti-twisting fixed block 7 is added to the bottom of the flange on the outside of the aviation head shell body 1. The high-strength fit between the fixed block 7 and the PCB board 3 is increased through the fixing groove 6 to increase the torque of the product. The position of the PCB board 3 can be secondary restricted by the fixing groove 6 and the fixing block 7. At the same time, the PCB board 3 and the flat surface of the aviation head shell body 1 are more closely fitted, and the overall anti-twisting property is increased through the high-strength fit.

[0035] Embodiment three:

[0036] like Figure 1 , Figure 6 and Figure 7The technical solution shown is based on Example 2, in order to solve the problem that the fixing groove 6 and the fixing block 7 are prone to loosening when they are engaged: the aviation head shell with strong anti-twisting ability discloses a sealing mechanism, and a sealing mechanism for increasing the fitting strength is arranged on one side between the fixing groove 6 and the fixing block 7, the sealing mechanism includes a pressing block 8, and the pressing block 8 is fixedly connected to the upper end of one side of the fixing block 7, a first airbag 9 is arranged on the inner side of the fixing groove 6 below the pressing block 8, and the bottom end of the first airbag 9 is fixedly connected to the second airbag 11 through a hose 10, the second airbag 11 is fixedly connected to one side between the fixing groove 6 and the fixing block 7, and a sealing layer 12 is arranged on the inner side of the second airbag 11, the cross-section of the sealing layer 12 is in the shape of a "C", and the inner side of the sealing layer 12 is in contact with the outer side of the fixing block 7.

[0037] In this example, when the PCB board 3 is fitted between the fixing groove 6 and the fixing block 7 to increase the anti-twisting ability, the pressing block 8 at one end of the fixing block 7 will press the first airbag 9, so that the gas inside the first airbag 9 is transported to the inside of the second airbag 11 through the hose 10, thereby expanding the second airbag 11. At the same time, the sealing layer 12 fits with the outer side of the fixing block 7, so that the gap between the fixing groove 6 and the fixing block 7 is reduced, so that the fixing groove 6 and the fixing block 7 can be more tightly engaged, thereby effectively avoiding the loosening of the fixing groove 6 and the fixing block 7 after engagement.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
