Description

Technical Field

[0001] The present application relates to the field of operating tool technology, and in particular to a gas valve socket joint extractor. Background Art

[0002] The gas valve connector is a crucial component during gas installation and operation. It creates a clear path for the natural gas entering the gas stove. It also controls the amount of gas flowing through it. The gas valve connector connects to the gas pipe and the gas stove at both ends, so an interference fit is often used to prevent gas leaks at this location.

[0003] However, because the interference fit connection is too tight, and some kitchen fumes will adhere to the connection position through the blowing of air, it is very troublesome to replace or disassemble the valve joint, which brings great trouble to the operator during construction. Utility Model Content

[0004] In order to be able to quickly and conveniently remove the valve joint so that the gas valve joint can be easily replaced or disassembled, thereby reducing the operating difficulty and saving operating time for the operator, the present application provides a gas valve socket joint extractor.

[0005] The present application provides a gas valve socket joint extractor adopting the following technical solution:

[0006] A gas valve socket joint extractor comprises a fixed component abutting against the end of the valve on one side and an extrusion screw rotatably inserted into the fixed component along the axial direction, an extrusion screw hole is provided on the fixed component, the extrusion screw is rotatably inserted into the extrusion screw hole, a movable block is threadedly connected to the end of the extrusion screw away from the fixed component, a slide groove is provided in the middle of the movable block along the length direction, two clamping rods are symmetrically slidably arranged in the slide groove, the opposite sides of the middle of the two clamping rods are abutted against the side of the valve, and a driving component for controlling the sliding of the clamping rod is installed on the movable block.

[0007] By adopting the above technical solution, the movable block is adjusted to below the joint disassembly position. At this time, the fixed component abuts against the stepped position near the bottom of the valve joint, and the driving component drives the two clamping rods to move toward the middle together until they abut against the side of the joint. Then, the extrusion screw is rotated to move the movable block and the two clamping rods inside the movable block away from the fixed component, thereby generating an extrusion force on the joint and pushing the joint out. The operation is simple and the structure is stable, avoiding the use of one-side clamping method to cause uneven force on the joint and difficulty in extrusion.

[0008] Optionally, the driving assembly includes two mounting brackets symmetrically arranged on the movable block, a bidirectional screw rotatably passed through the two mounting brackets, and racks respectively fixedly mounted on the two clamping rods on one side away from the fixed assembly, the two racks are respectively threadedly connected to the two ends of opposite threads on the bidirectional screw, and the movable block is provided with a driving member for driving the bidirectional screw.

[0009] By adopting the above technical solution, the driving member drives the bidirectional screw to rotate on the mounting frame, so that the rack threadedly connected to the bidirectional screw and the clamping rod fixedly connected to the rack move in the slide groove along the width direction of the slide groove. This method can make the sliding process of the clamping rod smoother and facilitate the adjustment of the width between the two clamping rods to ensure that the clamping rod can always remain in close contact with the side of the joint during the rotation of the extrusion screw.

[0010] Optionally, the driving member is a toggle wheel fixedly sleeved on the middle part of the bidirectional screw, and a plurality of toggle teeth are integrally provided on the toggle wheel along the circumference for facilitating manual rotation of the toggle wheel.

[0011] By adopting the above technical solution, the operator can drive the bidirectional screw more conveniently, and the driving wheel is located in the middle of the bidirectional screw, which can make the force on the bidirectional screw more uniform and avoid excessive shear force on the bidirectional screw in the radial direction.

[0012] Optionally, the fixing assembly includes a fixing block rotatably connected to the end of the extrusion screw and two abutment clamping rods symmetrically slidably arranged on the fixing block. A mounting groove is opened on one side of the fixing block along the length direction. The two abutment clamping rods are slidably arranged side by side in the mounting groove. The two abutment clamping rods are jointly clamped on both sides of the valve, and the lower ends of the two abutment clamping rods are abutted against the stepped position of the valve.

[0013] By adopting the above technical solution, when installing the extractor device, it is only necessary to slide the abutting clamp rod to clamp the valve body, and then make the abutting clamp rod abut against the valve step position to complete the fixation of the extruder. The operation is simple, and there is no need to limit the size of the valve during the installation of the extruder, thereby improving the simplicity of extruder installation.

[0014] Optionally, a through hole is provided transversely at one end of the two abutting clamping rods away from the fixed block, and a long bolt is passed through the two through holes. A fixing nut is threadedly connected to the end of the long bolt, and the bolt head of the long bolt and the fixing nut respectively abut against the opposite outer sides of the two abutting clamping rods.

[0015] By adopting the above technical solution, the two adjusted abutment clamping rods are fixed so that the two abutment clamping rods can always abut against the side of the valve, avoiding the situation where the joint cannot be pushed due to the unstable clamping structure during the rotation of the extrusion screw. At the same time, it can also make the extrusion operation easier, and there is no need to hold the abutment clamping rod at all times to prevent it from loosening.

[0016] Optionally, one end of the extrusion screw extends out of the fixing component away from the movable block, and a rotating handle is fixedly provided on the end extending out of the fixing component for easy handholding.

[0017] By adopting the above technical solution, since the equipment is small, the extrusion stroke is also small. Installing a handle can facilitate manual operation of the extrusion process and improve the safety and simplicity of the operating steps.

[0018] Optionally, the middle portion of the clamping rod is an arc-shaped structure, and the inner sides of the arc-shaped structures on the two clamping rods are close to each other.

[0019] By adopting the above technical solution, there is a larger contact area between the clamping rod and the joint, which improves the clamping stability and prevents the joint from sliding along the length of the clamping rod during the clamping process, causing uneven force on the entire equipment.

[0020] Optionally, the side wall of the slide groove is provided with a plurality of mutually parallel limiting strips perpendicular to the extension direction of the slide groove, and the clamping rod is provided with a plurality of limiting grooves perpendicular to the extension direction, and the plurality of limiting grooves correspond one to one with the plurality of limiting strips.

[0021] By adopting the above technical solution, it is possible to avoid the clamping rod sliding along the length direction of the slide groove during the clamping process, causing the clamping center to shift and making the clamping operation impossible.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application designs a structure for removing the joint of the gas valve, which makes the structure more convenient to install and operate while ensuring that the structure can be used normally, and improves the convenience of the joint removal operation;

[0024] 2. This application provides a fixed component, a threaded extrusion structure between the movable blocks, and a clamping structure between the clamping rods, so that the structure of the removal device can remain stable during the overall operation to avoid accidents.

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] The embodiment of the present application discloses a gas valve socket joint extractor.

[0032] Reference Figure 1 , a gas valve socket joint extractor, comprising a fixed component 1 abutting against the end of the valve on one side and an extrusion screw 2 rotatably inserted through the fixed component 1 and extending out of the valve end position. The extrusion screw 2 is threadedly connected at the end away from the fixed component 1 with a movable block 3 for squeezing the joint so that the joint can be separated from the valve. A slide groove 31 is provided in the middle of the movable block 3 along the length direction of the movable block 3, and two clamping rods 4 arranged side by side are slidably inserted in the slide groove 31, and the clamping rods 4 can slide along the width direction of the slide groove 31. Two adjusting support rods 6 are symmetrically fixed on both sides of the fixed component 1, and a waist-shaped hole 61 is provided at the end of the adjusting support rod 6 away from the fixed component 1. Two limit screws 62 are detachably provided at both ends of the movable block 3, and the two limit screws 62 are respectively slidably provided in the two waist-shaped holes to limit the sliding of the movable block 3 along the axis direction of the extrusion screw 2.

[0033] Reference Figure 1 Furthermore, the lower end of the extrusion screw 2 extends out of the fixed assembly 1 and the fixed sleeve is provided with a rotating handle 21, so as to manually drive the extrusion screw 2 to rotate, so as to achieve stable operation and precise adjustment, and prevent the situation of applying excess kinetic energy to the joint.

[0034] Reference Figure 1 and Figure 2 Specifically, the middle part of the clamping rod 4 is an arc-shaped structure, and the inner middle parts of the arc-shaped structures on the two clamping rods 4 are close to each other, so as to increase the contact area between the valve and the clamping rod 4, improve the clamping stability, and avoid the valve and the clamping rod 4 from sliding during the clamping process, resulting in the separation of the extractor and the valve.

[0035] Reference Figure 1 and Figure 2 The two adjacent sides of the clamping rods 4 abut against the sides of the valve to clamp the valve. Simultaneously, the upper ends of the two clamping rods 4 abut against the lower end of the connector. The extrusion screw 2 drives the movable block 3 and the clamping rods 4 within it to move vertically, separating the connector from the valve.

[0036] Reference Figure 1 and Figure 3 The fixed assembly 1 includes a fixed block 11 that is arranged on one side of the valve and is arranged vertically parallel to the movable block 3, and two abutting clamping rods 15 that are slidably connected to the fixed block 11. Specifically, a mounting groove 111 is provided on the fixed block 11 on the side close to the valve along the length direction, and the two abutting clamping rods 15 are slidably arranged side by side in the mounting groove 111. The two abutting clamping rods 15 clamp the valve together, and the lower ends of the two ground clamping rods abut against the same cross-sectional step position on the valve, so that during the clamping process, the fixed assembly 1 will not move in the vertical direction. By rotating the extrusion screw 2, the distance between the movable block 3 and the fixed block 11 is continuously increased, thereby generating an extrusion force on the joint.

[0037] Reference Figure 3 The two abutting clamping rods 15, each with its axis aligned in the same vertical plane, are each provided with a through-hole 12 extending through the same end, distal from the drive assembly 5. These two through-holes 12 have equal diameters and are penetrated by a long bolt 13, the end of which is threadedly connected to a fixing nut 14. The fixing nut 14 and the long bolt 13 both abut against the opposing outer sides of the two abutting clamping rods 15, creating a clamping effect that prevents the two abutting clamping rods 15 from sliding along the length of the fixed block 11.

[0038] Reference Figure 1 and Figure 4 A limiting strip 311 is integrally provided on the bottom side of the slide groove 31 and arranged along the width direction of the slide groove 31. A limiting groove 41 corresponding to the limiting strip 311 and having the same size as the limiting strip 311 is provided on the clamping rod 4 to prevent the clamping rod 4 from sliding along the length direction of the slide groove 31, causing uneven force on the device and causing excessive pressure on local parts.

[0039] Reference Figure 1 and Figure 4The movable block 3 is equipped with a driving assembly 5 for controlling the two clamping rods 4 to move closer to or further away from each other along the width direction of the slide 31. The driving assembly 5 includes two mounting brackets 51 integrally mounted on one side of the movable block 3, and a bidirectional screw 52 that passes through the middle of the two mounting brackets 51. The ends of the bidirectional screw 52 are rotatably connected to the mounting brackets 51. The two mounting brackets 51 are coaxial and perpendicular to the clamping rods 4. The two mounting brackets 51 are symmetrically arranged on both sides of the slide 31 on the movable block 3 along the width direction. Racks 53 are installed on both clamping rods 4 along the width direction of the slide 31. The racks 53 are threadedly connected to the bidirectional screws 52. A driving member 54 for driving the bidirectional screws 52 to rotate is integrally mounted on the bidirectional screws 52.

[0040] Reference Figure 4 Specifically, the driving member 54 includes a toggle wheel 541 fixedly mounted on the middle part of the bidirectional screw 52. A plurality of toggle teeth 542 extending along the width direction are arranged circumferentially on the toggle wheel 541, so that the operator can drive the bidirectional screw 52 to rotate by toggle wheel 541.

[0041] The working principle of the gas valve socket joint extractor in the embodiment of the present application is as follows:

[0042] First, adjust the spacing between the clamping rods 4 to the maximum possible, position the movable block 3 over the outside of the valve, and ensure that the bottom of the fixed assembly 1 abuts the bottom of the valve. Next, rotate the toggle wheel 541, causing the bidirectional screw 52 to move the two clamping rods 4 closer together until the curved structures on the clamping rods 4 completely abut the side of the valve. At this point, ensure that the upper ends of the two clamping rods 4 abut the lower end of the connector.

[0043] Then, long bolts 13 are inserted into the through holes 12 and fixed with nuts 14 to secure the two clamping rods 4. Otherwise, the clamping rods 4 slide. Finally, the handle 21 is rotated, and driven by the extruded threads, the movable block 3 continuously moves away from the fixed assembly 1, pushing the connector and the valve apart.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
