Description

Technical Field

[0001] This utility model belongs to the field of pipe plug technology, and in particular relates to a quick-release pipe plug. Background Technology

[0002] The oil circuit system has pipelines for transporting oil and sealing mechanisms for sealing the ends of the pipelines. The sealing mechanism can prevent the oil circuit system from leaking during operation and causing accidents. The existing oil circuit system seals by blocking the oil circuit with plugs, installing nuts at the connection between the plug and the oil circuit, and then adding sealing rings to achieve the sealing effect.

[0003] Chinese utility model patent CN209325264U includes a pipe body and a rotating head. A fixing sleeve is provided on the outer wall of the pipe body, and slots are provided on both sides of the outer wall of the pipe body. A button auxiliary groove is provided on both sides of the outer wall of the fixing sleeve. A foolproof button is provided inside each button auxiliary groove. An upper pressure plate is provided at one end of the foolproof button, and a return spring is provided on the lower surface of the upper pressure plate. A lower pressure plate is provided at the other end of the return spring, and an insertion block is provided on the other side of the lower pressure plate. The other end of the insertion block passes through the button auxiliary groove and connects with the slot on the pipe body. A lead screw is provided on one side of the outer wall of the rotating head, and the other end of the lead screw passes through a threaded hole on the fixing sleeve and connects with a plug. This utility model, through a series of structural designs, allows the plug to be securely inserted into the pipe, and the plug can be easily removed for cleaning after prolonged use.

[0004] However, the above-mentioned device has the following technical problems in actual use:

[0005] 1. The above-mentioned device fixes the fixing sleeve by inserting the plug into the slot opened on the outer wall of the pipe. However, the above-mentioned device can only seal the end of specific pipes. During use, the outer wall of the pipe must have a slot to install the fixing sleeve, which limits the use of the above-mentioned device on the smooth outer side of the pipe.

[0006] Second, in addition, a sealing strip is provided on the outside of the plug of the above-mentioned device. The sealing strip is located on the inner wall of the pipe and fits against the inner circumferential wall of the pipe. The sealing strip is usually made of natural rubber. However, after natural rubber is soaked in oil for a long time, it will swell, soften and crack, resulting in poor sealing effect and oil leakage, thus failing to achieve the sealing effect. Summary of the Invention

[0007] This utility model provides a quick-release pipe plug, which aims to solve the problem that the above-mentioned device mentioned in the background art can only be used on specific pipes (for example, the pipe has a slot on the outer wall to accommodate the plug), and cannot be used on the smooth outer side of the pipe, which limits the application scenarios of the above device. At the same time, when the sealing strip is soaked in oil for a long time, the sealing strip will swell, soften and crack, resulting in poor sealing effect and oil leakage.

[0008] This utility model is implemented as follows: a quick-release pipe plug includes a pipe body with a plug cap at its end. The plug cap has a cover and a sealing element disposed within the cover. The cover is fitted onto the outside of the pipe body, and the sealing element is inserted into the end of the pipe body to seal the end of the pipe body. Furthermore, a leakage detection component is disposed inside the sealing element, which is connected to the cover and used to monitor oil leakage at the end of the pipe body. A connecting mechanism is disposed on the outside of the end of the pipe body, and the cover and the connecting mechanism are detachably connected. In this design, the connecting mechanism is fixedly installed on the outside of the pipe body via a detachable connection. The assembly of the connecting mechanism does not require specific fittings on the outer wall of the pipe body, reducing the installation difficulty of the connecting mechanism. It also allows for convenient installation of the connecting mechanism on the outside of a conventional pipe body, expanding the applicability of this device. Furthermore, when the plug cap is inserted into the inside of the end of the pipe body, it seals the end of the pipe body. The cover is installed on the connecting mechanism via a threaded connection, facilitating the quick removal of the plug cap.

[0009] In addition, a sealing strip is provided on the outside of the plug in this device. The sealing strip can effectively seal the gap between the plug and the inner wall of the pipe body to prevent oil leakage. At the same time, when the sealing strip swells, softens and cracks after long-term use, the seeping oil will enter the leakage hole and then enter the detection chamber. The operator can often observe the oil leakage through the transparent plate and choose whether to replace the plug cap according to the actual situation.

[0010] Preferably, the connecting mechanism includes: a fixing ring sleeved on the outside of the pipe body, and an annular sleeve provided on the side of the fixing ring near the plug cap; wherein the fixing ring has: two symmetrically arranged arc-shaped seats sleeved on the outside of the pipe body, each arc-shaped seat having an extension block integrally formed and fixedly installed at both ends; the extension block having a through hole; when the two arc-shaped seats are sleeved on the outside of the pipe body, the two extension blocks on the same side abut against each other, and the two through holes are concentrically aligned; a locking bolt, the threaded section of which passes through the two through holes respectively, and a locking nut threadedly connected to the threaded section of which; an arc-shaped plate is also fixedly installed on the side wall of each arc-shaped seat, the arc-shaped plate being sleeved on the outside of the pipe body; this solution In the assembly and connection mechanism, two arc-shaped seats are symmetrically fitted onto the outside of the pipe body at a certain distance from the end of the pipe body. Then, the two extension blocks at the same end of the two pipe bodies abut against each other, and the through holes on the two extension blocks are aligned concentrically. The threaded section of the locking bolt is inserted from one through hole, passes through the two through holes, and then the threaded section that comes out is threaded with a locking nut. The locking nut abuts against one extension block, thereby achieving the connection and fixation of the two arc-shaped seats on the outside of the pipe body. After the arc-shaped seats are installed, two arc-shaped plates are symmetrically fitted onto the outside of the pipe body, and the adjacent ends of the two arc-shaped plates abut against each other. The two arc-shaped plates enclose to form an annular sleeve fitted onto the outside of the pipe body. The annular sleeve is located on the side of the arc-shaped seat near the end (cap) of the pipe body.

[0011] Preferably, the cover is fitted outside the annular sleeve, and a first thread is provided on the inner peripheral wall of the end of the cover, and a second thread is provided on the outer wall of the two arc-shaped plates. The first thread and the second thread are threadedly connected. A connecting shaft is also fixedly installed on the end of the cover away from the pipe body, and a knob is fixedly connected to the end of the connecting shaft. In this scheme, after the connecting mechanism is assembled, the sealing element of the plug cap is inserted into the inner side of the end of the pipe body, so that the cover is fitted outside the pipe body. As the sealing element gradually moves towards the inner side of the end of the pipe body, the cover gradually moves closer to the connecting mechanism. When the end of the cover abuts against the annular sleeve, the connecting shaft can be manually controlled to rotate by the knob. The connecting shaft controls the rotation of the cover. The first thread on the inner wall of the cover and the second thread on the annular sleeve (on the outer wall of the two arc-shaped plates) are screwed together, thereby completing the assembly of the cover. After the cover is assembled, it can ensure that the sealing element is stably inserted into the inner side of the end of the pipe body to seal the end of the pipe body.

[0012] Preferably, the sealing element includes: a connecting seat fixedly installed on the inner side wall of the housing, and a plug is provided on the side wall of the connecting seat. The plug is inserted into the inner side of the end of the pipe body and transitionally fits with the inner diameter of the end of the pipe body. A sealing strip is also provided around the outer side of the plug, and the outer peripheral wall of the sealing strip abuts against the inner peripheral wall of the pipe body. In this embodiment, the sealing element has a plug and a connecting seat provided on one side of the plug and fixedly connected to the inner side wall of the housing. When the sealing element is inserted into the end of the pipe body, the plug first enters the inner side of the pipe body. Then, as the housing moves, the plug gradually penetrates deeper into the end of the pipe body. After the connecting seat enters the interior of the pipe body, a threaded connection can be made between the housing and the annular sleeve. At this time, the inner side of the end of the pipe body can be sealed by the plug and the sealing strip on its outer side, thereby preventing oil leakage.

[0013] Preferably, the leakage detection assembly includes: a detection cavity formed within the connector; a mounting base fixedly connected to the side wall of the plug near the connector; a mounting hole formed on the side wall of the connector; the mounting base fixedly connected to the mounting hole; and multiple leakage holes formed at equal angles on the mounting base, one end of each leakage hole being positioned between the connector and the plug, and the other end communicating with the detection cavity. In this embodiment, the mounting base is installed on the side wall of the plug near the connector, and the mounting base is partially inserted into the mounting hole formed on the side wall of the connector. Furthermore, the mounting base and the mounting hole are fixedly connected, and there is a seamless connection between the mounting base and the mounting hole. The mounting base creates a certain gap between the plug and the connecting base. At the same time, the diameter of the mounting base is smaller than the diameter of the plug, which allows leaking oil to quickly enter the leakage hole. The mounting base has several leakage holes. When the sealing strip (plug) can no longer seal the oil in the main body of the pipe, some oil will seep into the mounting base through the gap and enter the detection chamber through the leakage holes. The operator can frequently observe the oil condition in the detection chamber to determine if there is a leakage problem.

[0014] Preferably, the cover is further provided with at least one observation port, the observation port is connected to the detection chamber, and a transparent plate is fixedly installed inside the observation port; in this solution, the observation port connected to the detection chamber is provided on the cover, and the transparent plate installed inside the observation port allows the staff to easily observe from the outside of the cover whether there is oil in the detection chamber, thereby determining whether the block can detect the oil in the pipeline body.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a quick-release pipe plug:

[0016] 1. This device has a connecting mechanism fixedly installed on the outside of the pipe body via a detachable connection. The assembly of the connecting mechanism does not require the installation of specific fittings on the outer wall of the pipe body, reducing the installation difficulty of the connecting mechanism. At the same time, it can be easily installed on the outside of the conventional pipe body, which improves the applicability of this device. In addition, when the plug is inserted into the inside of the end of the pipe body, it can seal the end of the pipe body. The cover is installed on the connecting mechanism via a threaded connection, which can facilitate the quick removal of the plug in the future.

[0017] A sealing strip is installed on the outside of the plug. The sealing strip can effectively seal the gap between the plug and the inner wall of the pipe body to prevent oil leakage. At the same time, when the sealing strip swells, softens and cracks after long-term use, the seeping oil will enter the leakage hole and then enter the detection chamber. The operator can often observe the oil leakage through the transparent plate and choose whether to replace the plug cap according to the actual situation. Attached Figure Description

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0028] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Please see Figure 1-5 This utility model provides a technical solution: a quick-release pipe plug, comprising: a pipe body 1, with a plug cap 2 at its end, wherein the plug cap 2 has: a cover 21 and a sealing element 22 disposed inside the cover 21, the cover 21 is fitted on the outside of the pipe body 1, and the sealing element 22 is inserted into the end of the pipe body 1 to seal the end of the pipe body 1, and a leakage detection component 23 is disposed inside the sealing element 22, the leakage detection component 23 is connected to the cover 21 and is used to monitor the oil leakage at the end of the pipe body 1, and a connecting mechanism 3 is disposed on the outside of the end of the pipe body 1, and the cover 21 and the connecting mechanism 3 are detachably connected.

[0033] Furthermore, the connecting mechanism 3 includes: a fixing ring sleeved on the outside of the pipe body 1, and an annular sleeve provided on the side of the fixing ring near the plug cap 2. The fixing ring has: two symmetrically arranged arc-shaped seats 31 sleeved on the outside of the pipe body 1. Each arc-shaped seat 31 has an extension block 32 integrally formed and fixedly installed at both ends. The extension block 32 has a through hole. When the two arc-shaped seats 31 are sleeved on the outside of the pipe body 1, the two extension blocks 32 on the same side abut against each other, and the two through holes are concentrically aligned. A locking bolt 33 has a threaded section that passes through the two through holes respectively, and a locking nut 34 is threadedly connected to the threaded section. An arc-shaped plate 35 is also fixedly installed on the side wall of each arc-shaped seat 31, and the arc-shaped plate 35 is sleeved on the outside of the pipe body 1.

[0034] Specifically, after the connecting mechanism 3 is assembled, in order to prevent the two arc-shaped seats 31 from slipping or deviating on the outside of the pipe body 1, rubber strips can be fixedly installed on the inner arc surfaces of the two arc-shaped seats 31. The rubber strips are arc-shaped and fit the inner arc surfaces of the arc-shaped seats 31. Anti-slip textures are provided on the rubber strips. At the same time, after the arc-shaped seats 31 are assembled, the rubber strips are used to seal the gap between the inner arc surfaces of the arc-shaped seats 31 and the outer wall of the pipe body 1, thereby increasing the friction between the arc-shaped seats 31 and the pipe body 1 and preventing the arc-shaped seats 31 from shaking or moving.

[0035] Furthermore, the cover 21 is fitted onto the outside of the annular sleeve, and the inner circumferential wall of the end of the cover 21 is provided with a first thread 211, and the outer walls of the two arc-shaped plates 35 are provided with a second thread 212. The first thread 211 and the second thread 212 are threaded together. A connecting shaft 213 is also fixedly installed on the end of the cover 21 away from the pipe body 1, and a knob 214 is fixedly connected to the end of the connecting shaft 213.

[0036] Furthermore, the sealing element 22 includes: a connecting seat 221 fixedly installed on the inner side wall of the housing 21, and a blocking block 222 is provided on the side wall of the connecting seat 221. The blocking block 222 is inserted into the inner side of the end of the pipe body 1 and transitionally fits with the inner diameter of the end of the pipe body 1. A sealing strip 223 is also provided around the outer side of the blocking block 222, and the outer peripheral wall of the sealing strip 223 abuts against the inner peripheral wall of the pipe body 1.

[0037] Specifically, in other solutions, when the sealing strip 223 on the outside of the plug 222 swells, softens and cracks, it cannot seal the oil inside the main body of the pipe 1. At this time, the oil will leak and the sealing element 22 can no longer provide an effective sealing effect. At this time, the sealing element 22 needs to be replaced.

[0038] In other designs, the outer wall of the mounting base 232 away from the connecting base 221 is provided with an external thread, and the plug 222 is an annular block with a fixing hole on its side wall to accommodate the mounting base 232. The fixing hole is provided with an internal thread, and the external thread and the internal thread are threaded together. When leakage occurs, the plug 222 can be replaced, thereby reducing the maintenance cost of the device and improving the replacement efficiency of the device.

[0039] It should be explained that the sealing strip 223 in this device is made of rubber. When it is freely extended, its height is slightly greater than the distance between the plug 222 and the inner wall of the pipe body 1. When the plug 222 is inserted into the pipe body 1, the sealing strip 223 will undergo compression deformation, thereby better sealing the gap.

[0040] Furthermore, the leakage detection component 23 includes: a detection cavity 231 opened in the connecting seat 221; a mounting seat 232 fixedly connected to the side wall of the plug 222 near the connecting seat 221; a mounting hole opened on the side wall of the connecting seat 221; the mounting seat 232 fixedly connected in the mounting hole; and a plurality of leakage holes 233 opened at equal angles on the mounting seat 232. One end of each leakage hole 233 is located between the connecting seat 221 and the plug 222, and the other end is connected to the detection cavity 231.

[0041] Specifically, a sealing strip 223 may also be provided on the outside of the connecting seat 221 in this device. The sealing strip 223 has the same shape, size and function as the sealing strip 223 provided on the outside of the plug 222. When the sealing strip 223 on the outside of the plug 222 is damaged, the oil can be sealed again by the sealing strip 223 on the outside of the connecting seat 221, and the oil can be stably entered into the leakage hole 233.

[0042] Furthermore, at least one observation port 234 is provided on the cover 21, the observation port 234 is connected to the detection cavity 231, and a transparent plate 235 is fixedly installed inside the observation port 234.

[0043] Specifically, observation port 234 can be configured with two (e.g. Figure 3 As shown, two observation ports 234 are symmetrically arranged on both sides of the connecting shaft 213.

[0044] The working principle and usage process of this utility model: After this utility model is installed,

[0045] When it is necessary to seal the end of the pipe body 1, firstly, two arc-shaped seats 31 are symmetrically fitted on the outside of the pipe body 1 and at a certain distance from the port of the pipe body 1. Then, two extension blocks 32 on the same side abut against each other. After the threaded section of the locking bolt 33 passes through the two through holes on the two extension blocks 32 on the same side, the locking nut 34 is threaded onto the threaded section to complete the assembly of the connecting mechanism 3.

[0046] Insert the sealing element 22 in the plug cap 2 into the inner side of the end of the pipe body 1, while the cover 21 is fitted onto the outer side of the pipe body 1. As the sealing element 22 gradually moves into the pipe body 1, the cover 21 approaches the two arc plates 35. When the cover 21 contacts the two arc plates 35, rotate the plug cap 2. The cover 21 is threaded onto the connecting mechanism 3 through the threaded engagement of the first thread 211 and the second thread 212, thus preventing the plug cap 2 from detaching.

[0047] When the device is used for a long time, the sealing strip 223 will swell, soften and crack. The leaked oil will enter the detection chamber 231 through the leakage hole 233. The person can observe the leakage in the detection chamber 231 through the observation port 234 and then choose whether to replace the plug cap 2 according to the actual situation.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
