Description

Technical Field

[0001] The utility model relates to the field of corrugated sealing pipes, in particular to a novel corrugated sealing pipe structure. Background Art

[0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and expansion direction. Bellows are widely used in instruments and meters. Their main purpose is to be used as a measuring element for pressure measuring instruments to convert pressure into displacement or force. The bellows has a thinner wall and higher sensitivity. The measuring range is from tens of Pa to tens of MPa. Its open end is fixed, the sealed end is in a free state, and an auxiliary coil spring or reed is used to increase elasticity.

[0003] A Chinese patent with announcement number CN208138465U provides a bellows for mechanical seals, which relates to the technical field of bellows and includes a bellows installed in a sealing seat. The bellows includes an outer trough and an outer crest. An anti-twist sleeve is provided on the outer sleeve of the bellows. The anti-twist sleeve is fixedly connected to the sealing seat. Several clips extend outward from the outer crests, and the length direction of the clips is parallel to the axis of the bellows. A slot is provided on the inner wall of the anti-twist sleeve for the clips to be embedded.

[0004] In summary, the above structure needs to add a sealing gasket in order to improve the tightness of the connection between the two during use, but it wastes too much manpower and material resources during the subsequent disassembly and assembly process, and the sealing gasket is easily damaged during disassembly, thereby reducing the overall service life. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a new type of corrugated sealing tube structure to solve the technical problem that the sealing gasket needs to be disassembled back and forth during use, which wastes too much manpower and material resources, and is very likely to cause damage to the sealing gasket during disassembly, thereby reducing the overall service life.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of corrugated sealing tube structure, including a tube body, both ends of the tube body are connected to a connecting head, a pressure plate is elastically and slidably arranged inside the connecting head, a clamping plate is arranged at the bottom of the pressure plate, a first plug rod is arranged in the clamping plate through the bottom of the pressure plate, a second plug rod cooperating with the first plug rod is connected to the clamping plate through an elastic component, and a sealing gasket is connected to the other end of the second plug rod through the clamping plate.

[0007] By adopting the above technical solution, the pressure plate is squeezed inwardly, so that the first plug rod at the bottom end of the pressure plate moves inward. During this process, the first plug rod squeezes the second plug rod, so that the second plug rod drives the sealing gasket to slide inward, thereby realizing automatic installation of the sealing gasket. When the connection is subsequently released, the second plug rod drives the sealing gasket to be recovered into the groove through the cooperation of the restoring force of the compression spring and the elastic component. In this process, the disassembly and assembly burden of the staff is greatly reduced, and at the same time, the sealing gasket is prevented from being damaged during disassembly, thereby increasing the overall service life of the sealing gasket.

[0008] The utility model is further configured that a compression spring is connected to the bottom of the pressure plate, and the compression spring is located in the clamping plate to wrap the first insertion rod thereof.

[0009] By adopting the above technical solution, when the pressure plate slides inward, the compression spring itself is in a compressed state. When the subsequent staff disassembles the connecting head and the pipe fitting, the limiting work on the pressure plate will be released. At this time, the restoring force of the compression spring itself will drive the pressure plate to reset and slide upward, thereby driving the first insertion rod to move.

[0010] The utility model is further configured that an inner groove is provided on the top of the clamping plate, and the depth of the inner groove itself is the same as the overall thickness of the pressing plate.

[0011] By adopting the above technical solution, when the pressure plate is squeezed during the connection between the pipe fitting and the connector, the pressure plate can be stuck in the inner groove of the clamping plate. In this process, close contact between the pipe fitting and its clamping plate is ensured, further improving the sealing of the pipe fitting connection.

[0012] The utility model is further configured that the side wall of the clamping plate is provided with a groove for the sealing gasket to be clamped into.

[0013] By adopting the above technical solution, the sealing gasket can be tightly combined with the side wall of the clamping plate through the groove. This process facilitates the subsequent disassembly of the pipe fitting to prevent the sealing gasket from blocking the edge of the pipe fitting, thereby reducing the possibility of damage to the sealing gasket during the disassembly process.

[0014] The utility model is further configured such that the bottom end of the first insert rod and the end of the second insert rod away from the sealing gasket are both configured in a conical frustum shape.

[0015] By adopting the above technical solution, when the pressure plate drives the first insertion rod to slide, one end of the pressure plate will contact the second insertion rod. Since the end faces of both are conical frustum, the two can be further prevented from getting stuck during the sliding process.

[0016] The utility model is further configured that the top of the pressing plate is configured to be rough.

[0017] By adopting the above technical solution, the rough setting makes it easy to improve the sliding friction between the pressure plate and the pipe fitting, and effectively prevents the pipe fitting from slipping during the insertion process.

[0018] The utility model is further configured such that the tube body and the connector are detachably arranged.

[0019] By adopting the above technical solution, the detachable setting makes it convenient for subsequent staff to regularly replace the sealing gasket inside the connector, thereby increasing the overall service life of the device.

[0020] The utility model is further configured that the connecting head is penetrated by an array of bolt holes.

[0021] By adopting the above technical solution, the tightness of the connection between the device and the pipe fitting is improved through the cooperation between the bolt hole and the bolt assembly.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model has a pressure plate slidably arranged in the connecting head. During installation, the pressure plate is pressed inwardly, so that the first plug rod at the bottom end of the pressure plate moves inward and the compression spring is compressed. During this process, the first plug rod will squeeze the second plug rod, so that the second plug rod drives the sealing gasket to slide inward, thereby realizing automatic installation of the sealing gasket. When the connection is subsequently released, the second plug rod drives the sealing gasket to be recovered into the groove through the cooperation of the restoring force of the compression spring and the elastic component. During this process, the disassembly and assembly burden of the staff is greatly reduced, and at the same time, the sealing gasket is prevented from being damaged during disassembly, thereby increasing the overall service life of the sealing gasket.

[0029] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1

[0031] A new type of corrugated sealing tube structure, such as Figure 1-Figure 4 As shown, it includes a tube body 1, a connector 2, a sealing mechanism, a reset mechanism and a clamping mechanism. A detachable arrangement is provided between the tube body 1 and the connector 2. The detachable arrangement is convenient for subsequent staff to regularly replace the sealing gasket 8 inside the connector, thereby improving the overall service life of the device. The tube is clamped into the interior of the connector 2. A pressure plate 10 is provided due to the elastic sliding inside the connector 2. During this process, the tube will drive the pressure plate 10 to slide inward. A clamping plate 3 is provided at the bottom of the pressure plate 10. A first plug rod 5 is provided in the bottom of the pressure plate 10 through the clamping plate 3. During this process, the pressure plate 10 will drive the first plug rod 5 to slide together. Since a second plug rod 7 cooperating with the first plug rod 5 is connected to the clamping plate 3 through an elastic component, and the other end of the second plug rod 7 passes through the clamping plate 3 and is connected to a sealing gasket 8, during this process, the first plug rod 5 will squeeze the second plug rod 7, so that the second plug rod 7 This drives the sealing gasket 8 to slide inward, thereby automatically installing the sealing gasket 8. At the same time, a compression spring 6 is connected to the bottom of the pressure plate 10, and the compression spring 6 is located in the card plate 3 and wraps its first plug rod 5. During the process of the pressure plate 10 sliding inward, the compression spring 6 itself is in a compressed state. When the subsequent staff disassembles the connecting head 2 and the pipe fitting, the limiting work on the pressure plate 10 will be released. At this time, the restoring force of the compression spring 6 itself will drive the pressure plate 10 to reset and slide upward, thereby driving the first plug rod 5 to move with it. Since an elastic component is also provided at the second plug rod 7, the second plug rod 7 is reset and slid together under the action of the elastic component, thereby completing the recovery of the sealing gasket 8. In this process, the disassembly and assembly burden of the staff is greatly reduced, and at the same time, the sealing gasket 8 is prevented from being damaged during disassembly, thereby improving the overall service life of the sealing gasket 8.

[0032] See also Figure 2 and Figure 4 The side wall of the clamping plate 3 is provided with a groove 4 for the sealing gasket 8 to be inserted into. The groove 4 facilitates the sealing gasket 8 to be tightly combined with the side wall of the clamping plate 3. This process facilitates the subsequent disassembly of the pipe fitting to prevent the sealing gasket 8 from blocking the edge of the pipe fitting, thereby reducing the possibility of damage to the sealing gasket 8 during the disassembly process.

[0033] See also Figure 4 The bottom end of the first plug rod 5 and the end of the second plug rod 7 away from the sealing gasket 8 are both arranged in a conical cone shape. When the pressure plate 10 drives the first plug rod 5 to slide, one end thereof will contact the second plug rod 7. Since the end faces of both are arranged in a conical cone shape, the two can be further prevented from getting stuck during the sliding process. Embodiment 2

[0034] like Figure 3 A new type of corrugated sealing tube structure is shown, and its overall structure is similar to that of Example 1, wherein an inner groove 9 is provided on the top of the clamping plate 3, and the depth of the inner groove 9 itself is the same as the overall thickness of the pressure plate 10. When the pressure plate 10 is squeezed during the connection between the pipe fitting and the connector 2, the pressure plate 10 can be inserted into the inner groove 9 of the clamping plate 3. In this process, close contact between the pipe fitting and its clamping plate 3 is ensured, thereby further improving the sealing of the pipe fitting connection.

[0035] The working principle of the utility model is as follows: when in use, the connecting head 2 and its pipe are clamped together, and the pipe will be clamped to the inside of the connecting head 2 to squeeze the pressure plate 10. During this process, the pressure plate 10 will drive the first plug rod 5 at the bottom to move, and the compression spring 6 at the bottom end is in a compressed state. During this process, the first plug rod 5 will cause the second plug rod 7 to move to one side, so as to push the sealing gasket to the outer wall of the pipe. During this process, the installation of the sealing gasket is realized. During subsequent disassembly, the first plug rod 5 is reset and slid by the reset force of the compression spring 6. At this time, the second plug rod 7 drives the sealing gasket 8 to be recovered into the groove 4 under the action of the elastic component, thereby completing the overall disassembly work. During this process, the disassembly and assembly burden of the staff is greatly reduced, and at the same time, the sealing gasket 8 is prevented from being damaged during disassembly.

[0036] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
