Description

Technical Field

[0001] This utility model relates to a sealing structure, specifically a convenient plug. Background Technology

[0002] A removable sealing structure is typically required at the port of a circular pipe to block or seal the pipe. However, the sealing structure must also be removed to open the pipe port when it is necessary to allow passage. Therefore, the ease of installation and removal, as well as the robustness of the sealing structure at the pipe port, are crucial. Current technology lacks a sealing structure that allows for easy installation and removal, hindering the rapid opening and sealing of circular pipe ports. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a convenient plug that can quickly open the port of the blocked pipe and is easy to operate.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A convenient plug includes a housing, control components, and several locking parts;

[0006] The control assembly includes a control lever and a linkage platform, with the control lever and the linkage platform being threaded together; the control lever is rotatably mounted on the housing, and the control end of the control lever extends out of the housing; the outer wall of the linkage platform is provided with a plurality of guide grooves, and each guide groove is inclined along the same axial direction;

[0007] The outer wall of the housing is provided with a plurality of through holes along the circumferential direction. One end of each of the plurality of clamping members is inserted into the plurality of through holes, and the other end of each of the plurality of clamping members is respectively engaged with a plurality of guide grooves on the linkage table.

[0008] The pipe port is provided with several slots, and each of the slots is connected to a clamping component.

[0009] The working principle of the aforementioned convenient head-covering device is:

[0010] When it is necessary to seal the pipe port, insert the convenient plug of this invention into the port, then rotate the control lever. The threaded engagement between the control lever and the linkage table causes the linkage table to move axially, guiding each clamping component radially outward under the guidance of the linkage table's guide groove. The clamping components then insert into the slots on the pipe port, completing the pipe port sealing. Similarly, when it is necessary to remove the plug, rotate the control lever in the opposite direction, causing the linkage table to move axially in the opposite direction and moving each clamping component radially inward, ultimately disengaging them from the slots on the pipe port, completing the plug removal.

[0011] In a preferred embodiment of this utility model, the housing includes an outer shell and an inner frame; the inner frame is connected to the side of the outer shell facing the port, and when the housing is assembled at the port, the inner frame is located inside the pipe, and the outer shell is adapted to the inner diameter of the port to achieve the sealing of the port.

[0012] Preferably, the control lever is rotatably connected to the outer shell and the inner frame, the control end of the control lever extends to the outside after passing through the outer shell, the linkage is located between the outer shell and the inner frame, and the control lever, the linkage, and the shell are coaxial.

[0013] Preferably, the inner frame is tapered, with its larger end connected to the outer shell and its smaller end extending inward, and a reinforcing part provided inside the inner frame.

[0014] In a preferred embodiment of this utility model, the linkage table is frustoconical in shape.

[0015] In a preferred embodiment of the present invention, the housing further includes a plurality of fixed brackets, one end of which is connected to the outer shell and the other end extends axially toward one side of the inner frame, and each fixed bracket is provided with a clearance hole; the clamping member passes through the clearance hole of the fixed bracket.

[0017] Preferably, the locking part includes a plurality of locking protrusions, which are spaced apart; the port has a plurality of slots, each slot being paired with each locking protrusion.

[0018] Preferably, a reinforcing gap is provided between the clamping portions of two adjacent clamping members; the housing is provided with a protrusion in the reinforcing gap, and a locking portion is provided at the port of the pipe corresponding to the protrusion; the protrusion and the locking portion are locked together by a locking structure.

[0019] In a preferred embodiment of this utility model, the slot is wedge-shaped; one end of the clamping member that engages with the slot matches the slot.

[0020] Compared with the prior art, the present invention has the following advantages;

[0021] This invention utilizes a rotating control lever and a linkage table to drive each clamping component, enabling the clamping component to engage or disengage with the slots on the pipe port. This allows for the sealing or removal of the end cap from the pipe port, making operation convenient and simple. Furthermore, the port has a slot that mates with the clamping component, and the clamping component is locked by the linkage table. The clamping component will not move as long as the linkage table remains stationary. Therefore, the clamping of the component and the slot provides excellent stability, enhancing the secure connection between the end cap and the port. Attached Figure Description

[0025] The present invention will be further described below with reference to the embodiments and accompanying drawings, but the implementation of the present invention is not limited thereto.

[0026] See Figures 1-3 This embodiment discloses a convenient plug, including a housing, a control component, and several locking components 7. The control component includes a control lever 6 and a linkage platform 8, with the control lever 6 and linkage platform 8 threaded together. The control lever 6 is rotatably mounted on the housing, and its control end extends outside the housing. The outer wall of the linkage platform 8 is provided with several guide grooves 9, each guide groove 9 being inclined along the same axial direction, meaning the distance between the guide groove 9 and the pipe axis gradually decreases or increases from the inside to the outside along the axial direction. Specifically, in this embodiment, the distance between the guide groove 9 and the pipe axis gradually decreases from the inside to the outside along the axial direction.

[0027] The outer wall of the shell is provided with several through holes 21 along the circumferential direction. One end of several clamping parts 7 is inserted into several through holes 21, and the other end of several clamping parts 7 is respectively engaged with several guide grooves 9 on the linkage table 8. The port of the pipe is provided with several slots 13, and several slots 13 are connected to several clamping parts 7.

[0028] Furthermore, the housing in this embodiment includes an outer shell 1 and an inner frame 2. The inner frame 2 is connected to the side of the outer shell 1 facing the port, and the inner frame 2 is located inside the pipe when the housing is assembled at the port. The inner diameter of the outer shell 1 is adapted to the inner diameter of the port to achieve the sealing of the port. Moreover, the side of the outer shell 1 facing the port of the pipe in this embodiment is provided with a first sealing ring 14, so that when the plug is locked at the port, the sealing treatment of the port can be improved.

[0029] Furthermore, to enable the rotation of the control lever 6, in this embodiment, the control lever 6 has rotatable connection positions with both the outer casing 1 and the inner frame 2. The control end of the control lever 6 extends to the outside after passing through the outer casing 1. The linkage platform 8 is located between the outer casing 1 and the inner frame 2, and the control lever 6, the linkage platform 8, and the casing are coaxial. To achieve the rotatable connection between the control lever 6 and the outer casing 1 and the inner frame 2, bearings 20 are provided between the control lever 6 and the outer casing 1, and between the control lever 6 and the inner frame 2 in this embodiment. The control end of the control lever 6 in this embodiment is specifically a handle, facilitating its rotational operation.

[0030] Furthermore, in this embodiment, the control lever 6 is provided with a threaded section, and the linkage 8 is provided with a threaded hole. The two work together to achieve a threaded engagement between the control lever 6 and the linkage 8. At the same time, a second sealing ring 15 is provided between the control lever 6 and the outer casing 1, and a third sealing ring 16 is provided between the control lever 6 and the linkage 8. These sealing rings can improve the sealing performance of the plug.

[0031] The inner frame 2 is conical, with its larger end connected to the outer shell 1 and its smaller end extending inward. The inner frame 2 also has a reinforcing section 3 inside. This conical structure of the inner frame 2 creates a gradually tapering structure, facilitating insertion into the port of the pipe and creating a accommodating space between the inner frame 2 and the outer shell 1, which is convenient for the installation of components such as the clamping element 7, the linkage platform 8, and the control lever 6.

[0032] The linkage table 8 is shaped like a frustum of a cone. Furthermore, the linkage table 8 in this embodiment can be configured as a frustum of a cone, a frustum of a pyramid, etc., and can be flexibly configured according to actual conditions. The frustum-shaped structure gives the outer wall of the linkage table 8 a certain angle of inclination, making it easier to machine the guide groove 9 on the linkage table 8. Combined with the structure of the linkage table 8 itself, it forms a radial extension and retraction drive for each clamping component 7.

[0033] The housing also includes several fixed brackets 4, one end of which is connected to the outer shell 1, and the other end extends axially toward one side of the inner frame 2. Each fixed bracket 4 is provided with a clearance hole 5. The clamping member 7 passes through the clearance hole 5 of the fixed bracket 4. The fixed brackets 4 further improve the stability of the clamping member 7 and provide support and limiting function for the clamping member 7.

[0034] The engagement between the clamping member 7 and the guide groove 9 on the linkage table 8 in this embodiment can be referred to in various linear guide structures in the prior art. For example, a guide block matching the guide groove 9 can be provided at the end of the clamping member 7. The guide block is limited in the guide groove 9 and can slide in the guide groove 9.

[0035] The clamping component 7 in this embodiment includes a linkage rod 17, a connecting plate 18, and a clamping part 19; the linkage rod 17 is connected to the connecting plate 18, and the linkage rod 17 extends radially toward the side close to the linkage table 8, and the linkage rod 17 is guided and engaged with the linkage table 8; the connecting plate 18 is fan-shaped, and the clamping part 19 is located at the outer diameter of the connecting plate 18.

[0036] In this embodiment, multiple clamping components 7 are provided. Since the connecting plate 18 of the clamping component 7 is arranged in a fan shape, the multiple clamping components 7 are arranged at equal intervals along the circumferential direction and are basically combined to form a complete circular structure. This allows the clamping part 19 on each clamping component 7 to form a basically complete circumferential clamping structure, thereby achieving a more reliable and secure clamping and sealing effect on the pipe port.

[0037] Furthermore, the locking part 19 includes multiple locking protrusions, which are spaced apart; multiple slots 13 are provided at the port, and each slot 13 is paired with each locking protrusion.

[0038] A reinforcing gap is provided between the clamping parts 19 of two adjacent clamping parts 7; the outer shell 1 of the housing has a protrusion 10 in the reinforcing gap, and a locking part 11 is provided at the port of the pipe corresponding to the protrusion 10; the protrusion 10 and the locking part 11 are locked together by a locking structure.

[0039] Furthermore, through holes can be provided on the protrusion 10 and the locking part 11, and the locking structure can be bolts 12 and nuts, so as to further reinforce and lock the shell and the port of the pipe, thereby improving the firmness.

[0040] In this embodiment, the slot 13 is wedge-shaped; the end of the clamping member 7 that mates with the slot 13 matches the slot 13.

[0041] See Figures 1-3 The working principle of the convenient head-covering device in this embodiment is as follows:

[0042] When it is necessary to seal the pipe port, insert the convenient plug of this invention into the port, then rotate the control lever 6. Utilizing the threaded engagement between the control lever 6 and the linkage 8, the linkage 8 moves axially, causing each clamping element 7 to extend radially outward under the guidance of the guide groove 9 of the linkage 8, and finally insert into the slot 13 on the pipe port, thus sealing the pipe port. Similarly, when it is necessary to remove the plug, rotate the control lever 6 in the opposite direction, causing the linkage 8 to move axially in the opposite direction, and causing each clamping element 7 to move radially inward, ultimately disengaging from the slot 13 on the pipe port, thus removing the plug.

[0043] The above are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
