Description
Technical Field
[0001] The present application relates to the field of rigid connectors, and in particular to a highly leak-proof rigid card. Background Art
[0002] A rigid connector is a rigid connector that is usually used to achieve a connection and locking operation on a metal pipe and is a commonly used accessory in metal pipe connections in the prior art.
[0003] In the prior art, the steel clip is usually made of cast iron, and its structure is usually set as two symmetrical semicircular arcs. A groove is opened inside the steel clip to clamp and lock the pipe flange when the pipeline is connected. In order to ensure the sealing of the steel clip during the pipeline connection process, a sealing rubber ring is usually arranged in the groove. In the prior art, the sealing rubber ring of the steel clip is usually only arranged inside the groove. In actual use, the sealing rubber ring does not fully wrap the flange of the pipeline connection, and the sealing rubber ring has a small coverage area on the connection, which easily leads to poor sealing tightness of the connection and leakage, affecting the running stability after the pipeline is connected.
[0004] Therefore, a high-sealing leak-proof steel clamp is proposed to solve some problems existing in the prior art, so as to avoid leakage and water seepage of the pipeline after being connected by the steel clamp. Utility Model Content
[0005] The purpose of the present application is to solve the problem in the prior art that the sealing rubber ring does not fully wrap the pipe connection flange during the use of the steel clamp, which is prone to water seepage and leakage after the connection. Compared with the prior art, a high-sealing and leak-proof steel clamp is provided, including a clamp a and a clamp b symmetrically arranged front and back, the clamp a and the clamp b are both arranged in a semi-circular arc structure, the upper and lower ends of the clamp a are fixedly connected with symmetrically arranged fixing blocks a, the upper and lower ends of the clamp b are fixedly connected with symmetrically arranged fixing blocks b, the fixing blocks a and the fixing blocks b located on the same side are fitted with each other, the fixing blocks a and the fixing blocks b are each provided with corresponding through holes and grooves, the internal hole groove of the fixing block a is movably inserted with a bolt extending into the internal hole groove of the fixing block b, and the outer thread of the bolt is sleeved with a nut pressed on the outer side of the fixing block b.
[0006] The inner sides of clamp a and clamp b are provided with interconnected grooves, and sealing rubber rings are embedded and installed in the grooves. The left and right edge positions of the sealing rubber rings are fixedly connected with side rubber rings extending toward the center of the circle, and the side of the side rubber rings away from the sealing rubber rings extends to the outside of the grooves.
[0007] By fixing the side rubber ring on the left and right sides of the sealing rubber ring, and arranging the side rubber ring to extend to the outside of the groove away from the side of the sealing rubber ring, the sealing rubber ring and the side rubber ring can be more tightly fitted at the connection position after being locked and squeezed by the clamp a and the clamp b when wrapped around the outside of the pipe flange, thereby achieving a more comprehensive wrapping, thereby further improving the sealing of the pipe connection, and helping to reduce the probability of water seepage and leakage after the pipe is connected.
[0008] Furthermore, the inner end walls on the left and right sides of the groove are provided with card slots, and the outer end walls on the left and right sides of the sealing rubber ring are equipped with card blocks that match the card slots.
[0009] Furthermore, gaskets are fixedly embedded in the upper and lower ends of the groove opened in the clamp a, and one end of the gasket extends into the groove opened in the clamp b.
[0010] Optionally, the hole groove opened inside the fixing block a is set to a circular hole structure, and the hole groove opened inside the fixing block b is set to a U-shaped groove structure.
[0011] Furthermore, the side of the fixing block a away from the clamp a is configured as an outwardly inclined structure, and the side of the fixing block b away from the clamp b is also configured as an outwardly inclined structure.
[0012] Furthermore, a positioning cylinder movably mounted on the outside of the bolt is fixedly installed in the internal hole groove of the fixing block a, and the length of the positioning cylinder is twice the thickness of the fixing block a.
[0013] Compared with the prior art, the advantages of this application are:
[0014] (1) By fixing the side rubber rings on the left and right sides of the sealing rubber ring, and arranging the side rubber rings to extend to the outside of the groove away from the side of the sealing rubber ring, the sealing rubber ring and the side rubber rings can be more tightly fitted at the connection position after being locked and squeezed by the clamp a and the clamp b when they are wrapped around the outside of the pipe flange, thereby achieving a more comprehensive wrapping, thereby further improving the sealing of the pipe connection, which is beneficial to reducing the probability of water seepage and leakage after the pipe connection.
[0015] (2) By opening the card slots on the inner end walls on the left and right sides of the groove, and assembling the card blocks that match the card slots on the left and right sides of the sealing rubber ring, the workers can use the card slots and the card blocks to pre-position the positions of the clamps a and b when installing the clamps a and b, which is beneficial to improving the convenience of the device during installation and tightening.
[0016] (3) By fixing the gasket at the upper and lower ends of the inner groove of the clamp a, and arranging the gasket to extend into the inner groove of the clamp b, the gap between the clamp a and the clamp b can be covered with the gasket, so that the extrusion and wear of the sealing rubber ring caused by the locking of the gap during the locking process of the clamp a and the clamp b can be reduced, thereby ensuring the stability of the device during use.
[0017] (4) By setting the hole groove on the fixing block b as a U-shaped groove structure, it can be ensured that the clamp b can be efficiently and conveniently disassembled and assembled during use, avoiding the presence of bolts affecting the convenience of its disassembly and assembly.
[0018] (5) By setting the sides of the fixing block a and the fixing block b that are close to each other to be inclined outward at the outer ends, a certain degree of gap is generated at the joint position of the fixing block a and the fixing block b, which is beneficial for applying prying force to separate the clamp a and the clamp b through the gap during the disassembly process, thereby improving the convenience of separating the clamp a and the clamp b during disassembly to a certain extent.
[0019] (6) By fixing a positioning tube of a certain length on the fixing block a and sleeved on the outside of the bolt, the extension direction of the bolt can be restricted to prevent the bolt from deflecting outward during the installation process, which is beneficial to ensuring the firm and stable connection of the device.

[0028] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.
[0029] Embodiment 1:
[0030] The utility model provides a high-sealing leak-proof steel card. Figure 1 - Figure 6 , including a clamp a1 and a clamp b101 symmetrically arranged in front and back, the clamp a1 and the clamp b101 are both arranged in a semicircular arc structure, the upper and lower ends of the clamp a1 are fixedly connected with symmetrically arranged fixing blocks a102, the upper and lower ends of the clamp b101 are fixedly connected with symmetrically arranged fixing blocks b103, the fixing blocks a102 and b103 located on the same side are fitted with each other, the fixing blocks a102 and b103 are internally provided with corresponding through holes, the internal holes of the fixing block a102 are movably inserted with bolts 104 extending into the internal holes of the fixing block b103, and the outer side of the bolts 104 is threadedly sleeved with nuts 105 pressed on the outer side of the fixing block b103.
[0031] The inner sides of the clamp a1 and the clamp b101 are both provided with interconnected grooves 2, and a sealing rubber ring 201 is embedded and installed in the groove 2. The left and right edge positions of the sealing rubber ring 201 are fixedly connected with side rubber rings 202 extending toward the center position of the circle, and the side rubber ring 202 extends to the outside of the groove 2 away from the side of the sealing rubber ring 201.
[0032] During the use of the steel clamp, the staff selects a suitable steel clamp according to the size of the connected pipe, and then connects the pipes to be connected so that the flanges on the two pipes to be connected are assembled together. The staff sets the sealing rubber ring 201 on the outside of the assembled pipe flanges, so that the side rubber rings 202 on the left and right sides of the sealing rubber ring 201 are wrapped around the left and right end walls of the assembled flanges. Then the staff clamps the clamp a1 and the clamp b101 on the outside of the sealing rubber ring 201 one after the other, so that the sealing rubber ring 201 and the side rubber ring 202 are embedded in the inside of the groove 2, inserts the bolt 104 into the hole groove opened in the fixing block a102 and the fixing block b103 on the same side, and locks the clamp a1 and the clamp b101 by rotating the nut 105 to achieve the sleeve connection of the pipe.
[0033] In the present application, the side rubber ring 202 is fixedly connected to the left and right sides of the sealing rubber ring 201, and the side rubber ring 202 is arranged to extend to the outside of the groove 2 away from the side of the sealing rubber ring 201, so that when the sealing rubber ring 201 and the side rubber ring 202 are wrapped around the outside of the pipe flange, they can be more tightly fitted at the connection position after being locked and squeezed by the clamp a1 and the clamp b101, thereby achieving a more comprehensive wrapping, thereby further improving the sealing of the pipe connection, and helping to reduce the probability of water seepage and leakage after the pipe is connected. Since the side rubber ring 202 extends to its center position for a sufficiently long length, it can effectively and comprehensively wrap the side end wall of the pipe flange connection, whether it is facing the connection of two large-diameter pipes or the connection of a large-diameter pipe and a small-diameter pipe, thereby ensuring its high sealing effect.
[0034] See also Figure 1 and Figure 4 A card slot 203 is provided on the left and right inner end walls of the groove 2, and a card block 204 adapted to the card slot 203 is mounted on the left and right outer end walls of the sealing rubber ring 201. During the use of the steel card, the card slot 203 is provided on the left and right inner end walls of the groove 2, and the card block 204 adapted to the card slot 203 is assembled on the left and right sides of the sealing rubber ring 201. This allows the staff to pre-position the positions of the clamp a1 and the clamp b101 with the help of the engagement of the card slot 203 and the card block 204 when installing the clamp a1 and the clamp b101, which is beneficial to improving the convenience of the device during installation and tightening.
[0035] See also Figure 1 The upper and lower ends of the groove 2 opened in the clamp a1 are fixedly inlaid with gaskets 3, and one end of the gasket 3 extends to the groove 2 opened in the clamp b101. During the use of the clamp, by fixing the gasket 3 at the upper and lower ends of the groove 2 in the clamp a1, and arranging the gasket 3 to extend into the groove 2 in the clamp b101, the gap generated by the splicing between the clamp a1 and the clamp b101 is blocked by the gasket 3, which can reduce the extrusion and wear of the sealing rubber ring 201 caused by the locking of the gap during the locking process of the clamp a1 and the clamp b101, thereby ensuring the stability of the device during use.
[0036] Embodiment 2:
[0037] The utility model provides a high-sealing leak-proof steel card. Figure 1 - Figure 6, including a clamp a1 and a clamp b101 symmetrically arranged in front and back, the clamp a1 and the clamp b101 are both arranged in a semicircular arc structure, the upper and lower ends of the clamp a1 are fixedly connected with symmetrically arranged fixing blocks a102, the upper and lower ends of the clamp b101 are fixedly connected with symmetrically arranged fixing blocks b103, the fixing blocks a102 and b103 located on the same side are fitted with each other, the fixing blocks a102 and b103 are internally provided with corresponding through holes, the internal holes of the fixing block a102 are movably inserted with bolts 104 extending into the internal holes of the fixing block b103, and the outer side of the bolts 104 is threadedly sleeved with nuts 105 pressed on the outer side of the fixing block b103.
[0038] The hole groove opened inside the fixing block a102 is set to a circular hole structure, and the hole groove opened inside the fixing block b103 is set to a U-shaped groove structure. During the use of the rigid clamp, by setting the hole groove on the fixing block b103 to a U-shaped groove structure, it can ensure that the clamp b101 can be efficiently and conveniently disassembled and assembled during use, avoiding the presence of the bolt 104 affecting its disassembly and assembly convenience.
[0039] See also Figure 2 The side of the fixed block a102 away from the clamp a1 is set to an outward inclined structure, and the side of the fixed block b103 away from the clamp b101 is also set to an outward inclined structure. During the use of the rigid clamp, by setting the sides of the fixed block a102 and the fixed block b103 close to each other to an outer end inclined outward structure, a certain degree of gap is generated at the splicing position of the fixed block a102 and the fixed block b103, which is beneficial to apply prying force to separate the clamp a1 and the clamp b101 through the gap during the disassembly process, thereby improving the convenience of separation between the clamp a1 and the clamp b101 during disassembly to a certain extent.
[0040] See also Figure 1 and Figure 2 A positioning tube 106 movably mounted on the outside of the bolt 104 is also fixedly installed in the internal hole groove of the fixed block a102, and the length of the positioning tube 106 is twice the thickness of the fixed block a102. During the use of the steel card, by fixing the positioning tube 106 with a certain length on the fixed block a102 and sleeved on the outside of the bolt 104, the extension direction of the bolt 104 can be restricted to prevent the bolt 104 from deflecting outward during the installation process, which is beneficial to ensure the firm and stable connection of the device.
[0041] The above are only the best implementation methods adopted by this application in combination with current actual needs, but the protection scope of this application is not limited to this.
