Description

Technical Field

[0001] The invention relates to the technical field of stainless steel connectors, and in particular to a fracture-resistant high-strength stainless steel connector. Background Art

[0002] Stainless steel connectors are components used to connect stainless steel pipes or other stainless steel parts. Because they are made of stainless steel, they have good corrosion resistance and can be used in a variety of environments. For example, they are not easy to rust or corrode in humid environments with chemical substances. They can effectively ensure the stability and service life of the connection structure. At the same time, they also have a certain strength and hardness, and can withstand certain external forces such as pressure and tension to ensure that the connection parts will not break or deform easily.

[0003] After searching, the Chinese invention patent with announcement number CN117948325B discloses a stainless steel anti-fracture high-strength connector, including a first connecting pipe, a second connecting pipe, an anti-fracture unit, a connecting unit, a disassembly unit, a steering unit, an adjustment unit and a positioning unit. The above device can install stainless steel at different angles through the connector, so that the connector can meet different installation conditions of stainless steel and adapt to different installation environments.

[0004] Based on the existing technology, the above patents still have the following shortcomings: when connecting steel pipes and other pipe fittings, it is necessary to open a threaded groove on the outer wall of the steel pipe to achieve the matching connection between the steel pipe and the connector. The entire installation process is time-consuming and laborious. At the same time, the docking fixation between the first connecting pipe and the second connecting pipe in the above patent is only achieved by the spring force to make the inclined surface press against the bottom of the arc-shaped fixing frame. The stability and strength are relatively poor and cannot meet people's anti-fracture needs. Therefore, an anti-fracture high-strength stainless steel connector is urgently needed to solve the above problems. Summary of the invention

[0013] Through the above technical scheme: the two groups of side grooves are in a fishtail shape, which can hook the lower clamping part, and the dovetail-shaped upper groove part has good rigidity and tightness when matched with the second clamping block, and can withstand large force and torque, and is not easy to loosen. At the same time, the dovetail-shaped upper groove part has a large connection area, which is conducive to dispersing force, increasing the connection strength, and further improving the stability and strength of the cooperation between the upper clamping part and the lower clamping part.

[0023] Through the above technical solution: since the first bevel gear is meshed with the second bevel gear, it can drive the second bevel gear and the threaded screw to rotate. Through the rotation of the threaded screw, the threaded sleeve meshed on its outer wall can drive the bent rod and the matching column to move horizontally, providing a power source for the rotation of the threaded screw.

[0024] The present invention is further configured such that a bent rod is fixedly connected to the circumferential outer wall of the threaded sleeve, and a matching column is fixedly connected to one end of the bent rod away from the threaded sleeve, and the cross-section of the matching column is semicircular, and a matching groove is provided on one side outer wall of one group of matching columns, and a matching block is fixedly connected to the one side outer wall of another matching column, and the matching block and the matching groove are clamped with each other.

[0025] Through the above technical solution: the two sets of second screws are effectively prevented from self-rotating and loosening, and the locking strength of the entire connecting piece is guaranteed.

[0026] The present invention is further configured such that a limiting groove is provided on the top outer wall of the fixed plate, a sliding rod is slidably connected inside the limiting groove, the bottom end of the sliding rod is fixedly connected to the circumferential outer wall of the threaded sleeve, a sliding block is fixedly connected to the top of the sliding rod, and the bottom outer wall of the sliding block is in contact with the top outer wall of the fixed plate.

[0027] Through the above technical solution: a good limiting and guiding effect can be played on the horizontal movement of the threaded sleeve, thereby ensuring the stability of the threaded sleeve during the horizontal movement.

[0028] The present invention is further configured as follows: the anti-loosening component includes a first gasket and a second gasket which are sleeved on the circumferential outer wall of the second screw, the first gasket, the second gasket and the nut are all pressed against each other, the top outer wall of the first gasket and the bottom outer wall of the second gasket are both provided with first wedge-shaped grooves which are equidistantly distributed in a circle, the bottom outer wall of the first gasket is provided with a second wedge-shaped groove, the top outer wall of the second gasket is fixedly connected with wedge-shaped teeth, the wedge-shaped teeth cooperate with the second wedge-shaped groove, and the inclination angle of the wedge-shaped teeth is greater than the pitch of the thread of the second screw.

[0029] Through the above technical solution: the vibration is offset by the tension between the wedge teeth and the second wedge groove. At the same time, because the inclination angle of the wedge teeth is greater than the pitch of the second screw thread, a wedge effect is generated at the nut, which effectively prevents the screw from loosening due to vibration.

[0030] The beneficial effects of the present invention are:

[0031] 1. The present invention effectively ensures the stability of the buckling of the upper clamping part and the lower clamping part through the mortise and tenon fixation between the first clamping groove, the second clamping groove and the first clamping block and the second clamping block. At the same time, the cross-section of the first clamping groove on both sides of the upper clamping part is T-shaped, so that it can provide lateral and longitudinal supporting forces after matching with the first clamping block, ensuring the stability of the clamping of the upper clamping part and the lower clamping part on both sides. The second clamping groove located in the middle is composed of side groove parts, upper groove parts and lower groove parts. The two groups of side groove parts are fishtail-shaped, which can hook the lower clamping part. The upper groove part in a dovetail shape has good rigidity and tightness when matching with the second clamping block, can withstand large force and torque, and is not easy to loosen. At the same time, the dovetail-shaped upper groove part has a large connection area, which is conducive to dispersing force, increasing connection strength, and further improving the stability and strength of the matching between the upper clamping part and the lower clamping part.

[0032] 2. The present invention can effectively prevent the two groups of second screws from self-rotating and loosening, and ensure the locking strength of the entire connecting piece. Specifically, the second screw, the long tooth column, the first bevel gear and the second bevel gear are provided. When the clamping hoop and the locking hoop are locked and fixed by the second screw, the rotation of the second screw can drive the gear plate to rotate together, and the gear plate and the long tooth column are meshed with each other. In the process of the gear plate rotating as the second screw descends, the long tooth column can still drive the long tooth column to rotate together. The rotation of the long tooth column can drive the first bevel gear to rotate, and the first bevel gear and the second bevel gear are engaged with each other. When the second set of second screws is locked, the mating block on one side of the other set of mating columns will be clamped in the mating groove of the mating column, thereby realizing the clamping and fixing of the two sets of mating columns. The two sets of mating columns can play a certain limiting role on the two sets of second screws.

[0033] 3. The present invention realizes the locking of the second screw by the tension generated when the second wedge-shaped grooves in the first gasket and the second gasket cooperate with the wedge-shaped teeth. During the use of the connecting piece after fixing and locking the first tube body and the second tube body, when a large vibration occurs at the connecting piece, the first gasket will mesh and lock with the second gasket to offset the vibration by tension. At the same time, the inclination angle of the wedge-shaped teeth is greater than the pitch of the second screw thread, so a wedge effect will be generated at the nut, which effectively avoids the loosening of the screw due to vibration and further improves the locking strength of the connecting piece.

DETAILED DESCRIPTION

[0044] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0045] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0046] Reference Figure 1-Figure 9 , a fracture-proof high-strength stainless steel connector, comprising a clamping hoop 1 and a locking hoop 2, the clamping hoop 1 comprising an upper clamping portion 1001 and a lower clamping portion 1002, the locking hoop 2 comprising an upper locking portion 2001 and a lower locking portion 2002, a mounting groove 3 is provided on the top outer wall of the upper locking portion 2001, a thread groove 21 is provided on the bottom of the mounting groove 3, a second screw 18 is connected to the inner thread of the thread groove 21, a nut 4 is fixedly connected to the top outer wall of the second screw 18, and an anti-loosening component is provided at the bottom of the nut 4;

[0047] The end of the second screw 18 away from the nut 4 is fixedly connected to the cylinder 13, and the bottom end of the cylinder 13 is fixedly connected to the first screw 15;

[0048] The diameters of the cylinder 13, the first screw 15 and the second screw 18 gradually increase. A circular groove 10 is provided at the bottom of the lower locking portion 2002. One end of the first screw 15 away from the cylinder 13 passes through the inside of the circular groove 10. One end of the first screw 15 is threadedly connected with a fixing nut 9. There are two sets of fixing nuts 9.

[0049] A reinforcing component 11 is provided inside the upper locking part 2001 and the lower locking part 2002, and the first tube body 19 and the second tube body 20 are respectively inserted into the inside of the clamping hoop 1 and the locking hoop 2, so as to realize the quick docking and fixation between the first tube body 19 and the second tube body 20. At the same time, by providing the reinforcing component 11 and the reinforcement part 27 at the connection between the clamping hoop 1 and the locking hoop 2, the strength of the entire connecting piece is effectively improved, and the connection piece is prevented from breaking at the connection between the clamping hoop 1 and the locking hoop 2 during use.

[0050] In order to ensure that the upper pressing part 1002 and the lower pressing part 1001 in the pressing hoop 1 fit more closely, refer to Figure 2-Figure 3The circumferential outer wall of the lower clamping part 1002 is respectively provided with a first clamping groove 5 and a second clamping groove 6. The number of the first clamping groove 5 is two groups, and the two groups of first clamping grooves 5 are respectively arranged on both sides of the second clamping groove 6. The cross section of the first clamping groove 5 is T-shaped. The second clamping groove 6 includes a side groove part 6001, an upper groove part 6002 and a lower groove part 6003. The number of the side groove parts 6001 is two groups, and the cross sections of the two groups of side groove parts 6001 are arc-shaped. The cross section of the upper groove part 6002 is dovetail-shaped. The circumferential outer wall of the upper clamping part 1001 is respectively fixedly connected with a first clamping block 7 and a second clamping block 8. The first clamping block 7 and the second clamping block 8 are respectively clamped with the first clamping groove 5 and the second clamping groove 6. The mortise and tenon fixation between the first clamping groove 5, the second clamping groove 6 and the first clamping block 7 and the second clamping block 8 effectively ensures that the upper clamping part 1002 and the lower clamping part 1001 are buckled. The first clamping groove 6002 is located on both sides of the upper clamping part 1002, and the cross section is T-shaped, so that it can provide lateral and longitudinal support force after cooperating with the first clamping block 7, ensuring the stability of the clamping of the upper clamping part 1002 and the lower clamping part 1001 on both sides. The second clamping groove 6 located in the middle is composed of a side groove part 6001, an upper groove part 6002, and a lower groove part 6003. The two groups of side groove parts 6001 are in a fishtail shape, which can hook the lower clamping part 1001, and the dovetail-shaped upper groove part 6002 has good rigidity and tightness when cooperating with the second clamping block 8, can withstand large forces and torques, and is not easy to loosen. At the same time, the dovetail-shaped upper groove part 6002 has a large connection area, which is conducive to dispersing force, increasing connection strength, and further improving the stability and strength of the cooperation between the upper clamping part 1002 and the lower clamping part 1001.

[0051] In order to prevent the connection between the clamping hoop 1 and the locking hoop 2 from breaking, refer to Figure 4 A reinforcement part 27 is fixedly connected to the circumferential inner wall of the locking hoop 2. The wall thickness of the reinforcement part 27 is greater than the wall thickness of the locking hoop 2. The reinforcement part 27 is located at one end of the locking hoop 2 close to the locking hoop 2. Since the wall thickness of the reinforcement part 27 is greater than the wall thickness of the locking hoop 2, it can play a role of reinforcing the connecting piece.

[0052] In order to ensure the strength of the entire connection, refer to Figure 4 The reinforcing component 11 includes a rod portion 1101 and a node portion 1102, and the number of the nodes 1102 is three groups. One group of rod portions 1101 is located in the middle of two groups of nodes 1102. The cross-section of the reinforcing component 11 is in the shape of a bamboo node. The reinforcing component 11 is fixedly connected to the circumferential inner wall of the reinforcement portion 27. Since the cross-section of the reinforcing component 11 is in the shape of a bamboo node, it can not only further improve the strength of the connection between the clamping hoop 1 and the locking hoop 2 to prevent the connecting piece from breaking during use, but also the interior of the reinforcing component 11 is a hollow structure, making the entire connecting piece more lightweight.

[0053] In order to ensure that the gear plate 14 can continue to provide a power source during the descent process, refer to Figure 3-Figure 4 The circumferential outer wall of the cylinder 13 is fixedly connected with a gear plate 14, and the gear plate 14 is meshed with a long tooth column 12. The top of the long tooth column 12 is rotatably connected to the circumferential inner wall of the rod portion 1101. The diameter of the gear plate 14 is smaller than the diameter of the second screw 18. When the staff locks and fixes the clamping hoop 1 and the locking hoop 2 through the second screw 18, the rotation of the second screw 18 can drive the gear plate 14 to rotate together. At the same time, the gear plate 14 and the long tooth column 12 are meshed with each other. In the process of the gear plate 14 descending and rotating with the second screw 18, the long tooth column 12 can still be driven to rotate together.

[0054] In order to ensure that the long tooth column 12 can rotate stably, refer to Figure 4 The circumferential inner wall of the rod portion 1101 is fixedly connected with a fixing plate 16, and the bottom end of the long tooth column 12 is rotatably connected to the fixing plate 16, thereby providing a certain rotation support for the bottom end of the long tooth column 12, thereby ensuring that the long tooth column 12 can rotate stably.

[0055] In order to provide a power source for the rotation of the threaded screw 17, refer to Figure 7-Figure 8 The bottom end of the long tooth column 12 is fixedly connected with a first bevel gear 24, and the first bevel gear 24 is meshed with a second bevel gear 25. The circumferential inner wall of the second bevel gear 25 is fixedly connected with a threaded screw 17. The two ends of the threaded screw 17 are rotatably connected with the circumferential inner wall of the rod part 1101 and the outer wall of one side of the fixed plate 16 respectively. The circumferential outer wall of the threaded screw 17 is meshed with a threaded sleeve 26. Since the first bevel gear 24 is meshed with the second bevel gear 25, it can drive the second bevel gear 25 and the threaded screw 17 to rotate. Through the rotation of the threaded screw 17, the threaded sleeve 26 meshed on its outer wall can drive the bent rod 30 and the matching column 28 to move horizontally.

[0056] In order to ensure the locking strength of the entire connector, refer to Figure 7-Figure 8 A bent rod 30 is fixedly connected to the circumferential outer wall of the threaded sleeve 26, and a matching column 28 is fixedly connected to the end of the bent rod 30 away from the threaded sleeve 26. The cross-section of the matching column 28 is semicircular. A matching groove is provided on the outer wall of one side of one group of matching columns 28, and a matching block 29 is fixedly connected to the outer wall of one side of the other matching column 28. The matching block 29 and the matching groove are clamped with each other, and the matching block 29 on one side of the other group of matching columns 28 will be clamped in the matching groove of the matching column 28, thereby realizing the clamping and fixing of the two groups of matching columns 28. Through the limiting effect of the two groups of matching columns 28, the two groups of second screws 18 are effectively prevented from self-rotation loosening, thereby ensuring the locking strength of the entire connecting piece.

[0057] In order to ensure that the threaded sleeve 26 can stably drive the bent rod 30 and the matching column 28 to move horizontally, refer to Figure 8A limiting groove 22 is provided on the top outer wall of the fixed plate 16, and a sliding rod is slidably connected inside the limiting groove 22. The bottom end of the sliding rod is fixedly connected to the circumferential outer wall of the threaded sleeve 26, and a slider 23 is fixedly connected to the top of the sliding rod. The bottom outer wall of the slider 23 contacts the top outer wall of the fixed plate 16. The slider 23 drives the sliding rod to slide inside the limiting groove 22, which can play a good limiting and guiding role in the horizontal movement of the threaded sleeve 26, thereby ensuring the stability of the threaded sleeve 26 during the horizontal movement.

[0058] In order to prevent the second screw rod 18 from loosening due to vibration, refer to Fig. 9 The anti-loosening assembly includes a first gasket 31 and a second gasket 32 ​​which are sleeved on the outer wall of the circumference of the second screw rod 18. The first gasket 31, the second gasket 32 ​​and the nut 4 are pressed against each other. The top outer wall of the first gasket 31 and the bottom outer wall of the second gasket 32 ​​are both provided with first wedge-shaped grooves 33 which are equidistantly distributed in a circle. The bottom outer wall of the first gasket 31 is provided with a second wedge-shaped groove 34. The top outer wall of the second gasket 32 ​​is fixedly connected with a wedge-shaped tooth 35. The wedge-shaped tooth 35 and the second wedge-shaped groove 34 are connected to each other. Correspondingly, the inclination angle of the wedge-shaped teeth 35 is greater than the pitch of the thread of the second screw 18. During the use of the connecting piece after fixing and locking the first tube body 19 and the second tube body 20, when a large vibration occurs at the connecting piece, the first gasket 31 will engage and lock with the second gasket 32 ​​to offset the vibration through tension. At the same time, the inclination angle of the wedge-shaped teeth 35 is greater than the pitch of the thread of the second screw 18, so a wedge effect will be generated at the nut 4, effectively preventing the screw from loosening due to vibration.

[0059] Working principle: When in use, the staff first places the lower clamping part 1001 and the lower locking part 2002 at the bottom of the first tube body 19, and then buckles the upper clamping part 1002, the upper locking part 2001 with the lower clamping part 1001, and the lower locking part 2002. In the process of buckling the upper clamping part 1002 with the lower clamping part 1001, the mortise and tenon fixation between the first clamping groove 5, the second clamping groove 6 and the first clamping block 7, the second clamping block 8 effectively ensures the stability of the buckling of the upper clamping part 1002 and the lower clamping part 1001. At the same time, the cross-section of the first clamping groove 5 on both sides of the upper clamping part 1002 is T-shaped, so that it can provide lateral and longitudinal support after cooperating with the first clamping block 7, ensuring the upper clamping part 1002 and the lower clamping part The stability of the clamping connection on both sides of 1001 is enhanced, and the second clamping groove 6 located in the middle is composed of a side groove portion 6001, an upper groove portion 6002, and a lower groove portion 6003. The two groups of side groove portions 6001 are in a fishtail shape, which can hook the lower clamping portion 1001, and the dovetail-shaped upper groove portion 6002 has good rigidity and tightness when matched with the second clamping block 8, can withstand large forces and torques, and is not easy to loosen. At the same time, the dovetail-shaped upper groove portion 6002 has a large connection area, which is conducive to dispersing force and increasing the connection strength, further improving the stability and strength of the cooperation between the upper clamping portion 1002 and the lower clamping portion 1001. Subsequently, when the staff locks and fixes the clamping hoop 1 and the locking hoop 2 through the second screw 18, the second screw 18 is rotated to The gear plate 14 can be driven to rotate together, and the gear plate 14 and the long tooth column 12 are meshed with each other. When the gear plate 14 rotates along with the second screw rod 18 descending, the long tooth column 12 can still be driven to rotate together. The rotation of the long tooth column 12 can drive the first bevel gear 24 to rotate, and the first bevel gear 24 is meshed with the second bevel gear 25, thereby driving the second bevel gear 25 and the threaded screw 17 to rotate. The rotation of the threaded screw 17 can make the threaded sleeve 26 meshed on its outer wall drive the bent rod 30 and the matching column 28 to move horizontally. When one set of the second screw rods 18 is fixed and locked, the matching column 28 will also stop moving. At this time, the staff rotates another set of the second screw rods 18, thereby driving another set of the matching columns 28 to move horizontally. When the two groups of second screw rods 18 are locked and fixed, the matching block 29 on one side of the other group of matching columns 28 will be clamped in the matching groove of the matching column 28, thereby realizing the clamping and fixing of the two groups of matching columns 28. Through the limiting effect of the two groups of matching columns 28, the two groups of second screw rods 18 are effectively prevented from self-rotation loosening, thereby ensuring the locking strength of the entire connecting piece. The second screw rod 18 is fixed and locked by the tension generated when the second wedge-shaped groove 34 in the first gasket 31 and the second gasket 32 ​​cooperates with the wedge-shaped teeth 35. During the process of using the connecting piece after fixing and locking the first tube body 19 and the second tube body 20, if a large vibration occurs at the connecting piece, the first gasket 31 will mesh and lock with the second gasket 32 ​​to offset the vibration through tension.At the same time, the inclination angle of the wedge-shaped teeth 35 is greater than the pitch of the second screw 18, so a wedge effect is generated at the nut 4, which effectively prevents the screw from loosening due to vibration.
