Description

Technical Field

[0001] This utility model relates to the field of pipeline protection technology, specifically to a pipeline outlet protection device. Background Technology

[0002] During pipeline construction, transition pipes need to be connected one by one. The pipe openings in the connection gaps are exposed to the outside for a long time, making them susceptible to collision damage, dust pollution, or water vapor erosion. Therefore, external protective devices are required for protection. In the pipeline protection device in utility model patent CN223609675U, it is a single rigid structure that can only fit the outer wall of pipes of a specific diameter. When dealing with transition pipes of different specifications, multiple sets of protective devices of different sizes need to be prepared. This not only increases the cost of equipment procurement and storage, but also requires frequent replacement of devices to adapt to different pipe openings, which seriously reduces construction efficiency. At the same time, when the rigid gasket fits the pipe with an incompatible diameter, the problem of "loose fixing of small-diameter pipes and inability to install on large-diameter pipes" is likely to occur, resulting in protection failure or pressure damage to the pipe surface. Summary of the Invention

[0003] The technical problem to be solved by this utility model is how to solve the problem of small diameter adaptation range and poor versatility of pipeline protection devices in the prior art.

[0004] The technical solution adopted by this utility model is as follows: a pipe opening protection device, including a fixing member, an adaptive gasket assembly, and a protective cover. The fixing member has a rotating boss at the end away from the pipe, and an adjusting through hole is provided inside the rotating boss. A pushing member and a pipe abutment are provided inside the adjusting through hole. The pushing member and the adjusting through hole are rotatably connected by a rotating shaft. The pushing member has a handle at the end away from the pipe abutment. A sliding groove is provided on the inner wall of the adjusting through hole. Sliding blocks are provided at both ends of the pipe abutment. The sliding blocks are slidably connected to the sliding groove. The pushing member abuts against the pipe abutment at the end near the pipe abutment. The adaptive gasket assembly is connected to the side of the fixing member facing the pipe. The adaptive gasket assembly includes an arc-shaped gasket and an adjusting elastic member. The fixing member and part of the arc-shaped gasket are provided with snap-fit ​​cavities. The protective cover is provided with an elastic pressing snap-fit ​​member, which snaps into the snap-fit ​​cavity.

[0005] The above structure has the following beneficial effects: (1) By rotating the pusher, the pipe abutment can be driven to slide along the groove, which can quickly adjust the fit between the device and pipes of different diameters. Furthermore, the pipe abutment is in close contact with the outer wall of the pipe, which enables the fastening of the fixing component.

[0006] (2) By using the arc-shaped gaskets of the adaptive gasket group and the adjusting elastic element to fit the outer wall of pipes of different specifications, the adaptability range of the device is effectively improved, avoiding the problem that the device can only protect pipes of a single specification due to the fixed specifications of the device.

[0007] (3) By setting elastic press-type snap-fit ​​parts on the protective cover and snapping them onto the fixing parts and arc-shaped gaskets, the process is convenient and the elastic press-type snap-fit ​​parts can also be adjusted according to different pipe diameters, which facilitates the installation of the protective cover.

[0008] Preferably, the end of the slide away from the pusher is provided with a reset cavity, and a sliding rod is provided in the reset cavity. A reset plate is provided on one side of the slider on the pipe abutment, and the reset plate is slidably connected to the sliding rod.

[0009] By setting a reset cavity and a sliding rod inside the reset cavity, the reset plate on the pipe abutment is slidably connected to the sliding rod. When the pushing component is rotated and the pipe abutment loses external force, the reset plate will slide along the sliding rod, thus preventing the movement path of the pipe abutment from deviating.

[0010] Preferably, a reset elastic element is sleeved on the sliding rod, one end of which abuts against the reset plate and the other end abuts against the inner wall of the reset cavity.

[0011] By setting a reset elastic element on the sliding rod and making the reset elastic element abut against the reset plate, when the pushing element rotates so that it no longer abuts against the reset plate, the reset elastic element can quickly reset the pipe abutment connected to the reset plate, avoiding manual reset.

[0012] Preferably, the cross-section of the end of the pusher near the pipe abutment is elliptical.

[0013] By setting the end of the pusher near the pipe abutment to an elliptical shape, the pipe abutment can be pushed with a small angle of rotation when the pusher is rotated, thereby allowing the pipe abutment to quickly abut against the pipe.

[0014] Preferably, multiple arc-shaped pads and multiple adjusting elastic elements are provided, and two adjacent arc-shaped pads are connected by the adjusting elastic elements.

[0015] By connecting multiple arc-shaped gaskets through an adjustable elastic element, it is possible to adapt to pipes of different specifications. The adjustable elastic element allows relative displacement between adjacent arc-shaped gaskets, which can compensate for minor deformations of the pipe, such as thermal expansion and contraction, and still maintain a good sealing effect under these conditions.

[0016] Preferably, the elastic press-type snap-fit ​​component has a limiting boss at one end facing the snap-fit ​​cavity, and the limiting boss abuts against the inner wall of the snap-fit ​​cavity.

[0017] By setting a limiting boss on the elastic pressing snap-fit ​​component, after the elastic pressing snap-fit ​​component is inserted into the snap-fit ​​cavity, the limiting boss abuts against the inner wall of the snap-fit ​​cavity under the elastic force of the elastic pressing snap-fit ​​component, thereby preventing the elastic pressing snap-fit ​​component from falling out of the snap-fit ​​cavity.

[0018] Preferably, the snap-fit ​​cavity is provided with an abutment plate, which abuts against the elastic press-type snap-fit ​​component.

[0019] By setting an abutment plate against a flexible press-fit connector, the connection stability between the protective cover and the fastener is ensured.

[0020] Preferably, the snap-fit ​​cavity is further provided with an abutting elastic member, one end of which abuts against the abutting plate and the other end of which abuts against the inner wall of the snap-fit ​​cavity.

[0021] By setting an abutting elastic element in the snap-fit ​​cavity and making the abutting elastic element abut against the abutting plate, the abutting elastic element provides elastic support for the abutting plate, so that the abutting plate abuts against the elastic pressing snap-fit ​​element inserted into the snap-fit ​​cavity and limits its movement, preventing the protective cover from moving during pipeline transportation.

Detailed Implementation

[0030] The following will be combined with the appendix Figure 1-6 The technical solution of this utility model is clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[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] Example The following description, in conjunction with specific embodiments, provides further details. Figure 1-6 As shown, this embodiment is a pipe opening protection device, including a fixing member 20, an adaptive gasket group 30 and a protective cover 40. The protective cover 40 is detachably snapped together with the fixing member 20 and the adaptive gasket group 30. The adaptive gasket group 30 includes an arc-shaped gasket 31 and an adjusting elastic member 32. The adaptive gasket group 30 is disposed on the side of the fixing member 20 facing the pipe 10. In this embodiment, the end of the fixing member 20 facing the pipe 10 is connected to the adjusting elastic member 32 in the adaptive gasket group 30. The adjusting elastic member 32 is made of soft material, and in this embodiment, it is made of rubber. The end of the fixing member 20 away from the pipe 10 is provided with a rotating boss 21. The rotating boss 21 is provided with an adjusting through hole 211. The inner wall of the adjusting through hole 211 is provided with a sliding groove 212 and a reset cavity 213. The reset cavity 213 is provided with a sliding rod 214. The adjusting through hole 211 is equipped with a pushing member 23 and a pipe abutment member 216. The pushing member 23 is a cam. The pushing member 23 is rotatably connected to the rotating boss 21 through a rotating shaft. The end of the pushing member away from the pipe abutment member is provided with a handle.

[0033] The pipe abutment 216 has sliders 2161 on both sides, and the sliders 2161 are slidably connected to the slide groove 212. The side of the slider 2161 away from the pipe abutment 216 has a reset plate 2162, which is slidably connected to the sliding rod 214. The sliding rod 214 is also fitted with a reset elastic element 215, which is a compression spring. One end of the reset elastic element 215 abuts against the reset plate 2162, and the other end abuts against the inner wall of the reset cavity 213.

[0034] The fastener 20 has a snap-fit ​​cavity 22 on the side facing the protective cover 40. The number of snap-fit ​​cavities 22 is the same as the number of elastic press-fit fasteners 41 provided on the protective cover 40. The snap-fit ​​cavity 22 has an abutting elastic member 221 and an abutting plate 222 inside. One end of the abutting elastic member 221 abuts against the abutting plate 222, and the other end abuts against the inner wall of the snap-fit ​​cavity 22. When the elastic press-fit fastener 41 on the protective cover 40 is inserted into the snap-fit ​​cavity 22, the elastic press-fit fastener 41 returns to its original position under its own elastic force. At this time, the limiting boss provided at the bottom of the elastic press-fit fastener 41 abuts against the inner wall of the snap-fit ​​cavity 22, and the abutting plate 222 abuts against the elastic press-fit fastener 41 under the action of the abutting elastic member 221, effectively preventing the protective cover 40 from shifting when it vibrates or moves with the pipeline 10.

[0035] Working principle: First, the staff puts the pipe opening protection device on the pipe opening of the pipe 10. Then, by turning the handle to push the pusher 23, the pipe abutment 216 set in the fixing part 20 moves towards the pipe 10 until the pipe abutment 216 abuts against the outer wall of the pipe 10, and ensures that the fixing part 20 will not move. During this process, multiple arc-shaped gaskets 31 in the self-adaptive gasket group 30 are tightly fitted to the outer wall of the pipe 10 under the action of the adjusting elastic element 32. Adjacent arc-shaped gaskets 31 form an annular fitting surface through the linkage of the adjusting elastic element 32, which adaptively adapts to the diameter difference of the pipe 10 to enhance the fixing stability. Then, align the protective cover 40 with the snap-fit ​​cavity 22 on the fixing member 20 and part of the arc-shaped gasket 31, press the elastic snap-fit ​​member 41 to make it retract and insert into the snap-fit ​​cavity 22. After releasing, the elastic snap-fit ​​member 41 resets under its own elastic force, and the limiting boss at its bottom end snaps into the inner wall of the snap-fit ​​cavity 22. At the same time, the elastic member 221 pushes the abutment plate 222 to press the elastic snap-fit ​​member 41, thereby achieving a stable fixation of the protective cover 40, and thus playing the role of preventing dust and foreign objects from entering the pipe opening of the pipe 10.

[0036] Similarly, during disassembly, press the elastic snap-fit ​​connector 41 to retract it inward, and then remove the protective cover 40 from the snap-fit ​​cavity 22. By rotating the handle, the pusher 23 is turned so that the pusher 23 no longer abuts against the pipe abutment 216. Under the action of the reset elastic member 215, the pipe abutment 216 moves away from the pipe 10 and no longer abuts against the pipe 10. Then it is easy to remove the pipe opening protection device from the pipe 10.
