Technical Field

[0001] The utility model relates to the technical field of water pipe components, and particularly relates to a quick plug for a boss water pipe orifice. Background Art

[0002] When the engine cooling water pipes are tested before leaving the factory, it is necessary to block the orifices of some water pipes. The traditional way to block the orifices is to cover the orifice with a rubber plug, and then use a clamp to lock the rubber plug to the boss of the orifice, so as to realize the sealing of the orifice. In the actual blocking process, it takes time to select a rubber plug suitable for the orifice size. At the same time, due to the high pressure in the engine water channel and the maximum water temperature of about 90°C, the rubber plug is easy to deform, and thus it is easy to break off during the test, affecting the safety of employees. At the same time, the short service life of the rigid clamp and the rubber plug affects the production cost, and the assembly and disassembly time affects the production efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide a quick plug for a boss water pipe orifice, which solves the problems of cumbersome plugging operation, poor plugging effect and low service life affecting the cost of the traditional rubber plug.

[0004] The utility model is realized by the following technical solutions: A quick plug for a boss water pipe orifice is arranged on the orifice and cooperates with a ring-shaped boss on the outer wall of the orifice to block the orifice, including a connecting sleeve, one end of the connecting sleeve is sleeved on the orifice and connected to the boss;

[0005] A plugging member, the plugging member includes a plug seat and a screw rod, the screw rod passes through the connecting sleeve and is in threaded cooperation with the connecting sleeve, the plug seat is slidably arranged in the connecting sleeve and connected to one end of the screw rod, and the plug seat is driven to move in the connecting sleeve by rotating the screw rod, so as to block the orifice with the plug seat.

[0006] Further, a plurality of pin holes are arranged in an annular array at one end of the connecting sleeve away from the screw rod, the pin holes are arranged radially, and locking pins are slidably arranged in the pin holes.

[0007] Further, an outer shell is slidably sleeved on the connecting sleeve, a driving ring is integrally arranged in the inner cavity of the outer shell, the pin holes are located on the moving path of the driving ring, when the driving ring is aligned with the pin holes, one end of the locking pin extends into the inner cavity of the connecting sleeve, and the inner diameter formed by the ends of a plurality of the locking pins away from the driving ring is smaller than the outer diameter of the boss.

[0008] Further, the locking pin is a steel ball.

[0009] Furthermore, the connecting sleeve is provided with a retaining spring on one end of the pin hole away from the screw rod, and the outer diameter of the retaining spring is larger than the inner diameter of the driving ring; when the driving ring abuts against the retaining spring, the driving ring is aligned with the pin hole.

[0010] Furthermore, an inclined surface is provided at one end of the drive ring close to the retaining spring.

[0011] Furthermore, it also includes a reset spring, which is sleeved on the connecting sleeve. The connecting sleeve is provided with an annular step near one end of the screw rod, and the two ends of the reset spring are respectively in contact with the step and the drive ring.

[0012] Furthermore, the blocking seat is rotatably connected to the screw rod.

[0013] Furthermore, it also includes a sealing gasket, which is arranged at an end of the blocking seat away from the screw rod.

[0014] Furthermore, a driving handle is provided at one end of the screw rod away from the blocking seat.

[0015] The technical solution of the utility model has at least the following advantages and beneficial effects:

[0016] 1. Before docking, the outer shell is moved to one side of the screw rod, and then the driving ring is separated from the several pin holes, and then does not abut against the steel ball. At this time, the reset spring will be compressed, and the connecting sleeve will be aligned with the pipe mouth until the boss of the pipe mouth passes over the several steel balls. In the process of the boss passing over the steel ball, the steel ball will be pushed outward, and the steel ball will be restricted by the outer shell and will not completely separate from the pin hole. Then the outer shell is loosened, and under the action of the reset spring, the outer shell is pushed to move away from the screw rod on the connecting seat, and then the driving ring pushes the steel ball back to the pin seat through the inclined surface until the driving ring abuts against the retaining spring. At this time, the inner wall of the driving ring is also aligned with the pin hole, so that the steel ball is located at the bottom of the pin hole, and the inner cavity diameter formed between the several steel balls is smaller than the outer diameter of the boss. Then, when the screw is rotated, after the plugging seat and the sealing gasket abut against the pipe mouth, the steel ball abuts against one end of the boss, so that the connecting seat does not separate from the pipe mouth, thereby providing a reaction force for the screw, which greatly improves the sealing efficiency and has a good sealing effect.

[0017] 2. The sealing gasket is made of rubber material and is arranged at the end of the plug seat away from the screw. The sealing gasket can better seal the gap between the plug seat and the end face of the pipe mouth, thereby making the sealing effect of the pipe mouth better. At the same time, even if the internal water temperature is high, it is squeezed and sealed here, and the plug seat will not rotate with the screw, so the service life of the sealing gasket and the plug seat is longer, and the sealing effect is good. It can be reused many times, reducing cost waste. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. Generally, the components of the embodiments of the present utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but only represents the selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Referring to Figure 1 As shown, this embodiment provides a quick plug for a boss water pipe orifice, which is arranged on the orifice 1 and cooperates with the annular boss 11 on the outer wall of the orifice 1 to seal the orifice 1. It includes a connecting sleeve 2 and a plugging member 3. One end of the connecting sleeve 2 is sleeved on the orifice 1 and connected to the boss 11;

[0024] The plugging member 3 includes a plug base 31 and a screw rod 32. The screw rod 32 passes through the connecting sleeve 2 and is in threaded cooperation with the connecting sleeve 2. The plug base 31 is slidably arranged in the connecting sleeve 2 and connected to one end of the screw rod 32. By rotating the screw rod 32, the plug base 31 is driven to move in the connecting sleeve 2, so as to seal the orifice 1 with the plug base 31; specifically, during implementation, the plug base 31 is rotatably connected to the screw rod 32; thus, when the plug base 31 is butted against the orifice 1, there will be no rotational friction with the orifice 1, and at the same time, it does not affect the rotation of the screw rod 32.

[0025] More specifically, as Figure 1 shown, it further includes a gasket 33. The gasket 33 is made of rubber material and is arranged at one end of the plug seat 31 away from the screw rod 32. Through the gasket 33, the gap between the plug seat 31 and the end face of the pipe orifice 1 can be better sealed, thereby making the sealing effect of the pipe orifice 1 better. At the same time, even if the water temperature inside is high, but here it is squeezed and sealed, and in addition, the plug seat 31 does not rotate with the screw rod 32. Therefore, the service life of the gasket 33 and the plug seat 31 is longer, and the sealing effect is good. When plugging the pipe orifice 1, after connecting the connecting sleeve 2 with the boss 11 of the pipe orifice 1, rotating the screw rod 32 can make the plug seat 31 and the gasket 33 cooperate to plug the pipe orifice 1. On the contrary, when removing, only need to rotate the screw rod 32 in the reverse direction, which improves the efficiency of the operation of plugging the pipe orifice 1.

[0026] At the same time, as Figure 1 shown, a driving handle 34 is arranged at one end of the screw rod 32 away from the plug seat 31. Through the driving handle 34, it is easier to drive the screw rod 32 to rotate forward and backward.

[0027] More specifically, a plurality of pin holes 21 are arranged in a circular array at one end of the connecting sleeve 2 away from the screw rod 32. The pin holes 21 are arranged along the radial direction, and a locking pin 22 is slidably arranged in the pin holes 21. After the connecting sleeve 2 is sleeved on the pipe orifice 1, make a plurality of locking pins 22 move towards the axis until they abut against one side of the boss 11 away from the pipe orifice 1. At this time, the connecting sleeve 2 is connected to the pipe orifice 1, and then rotating the screw rod 32 can make the plug seat 31 and the gasket 33 plug the pipe orifice 1, which is simple and fast.

[0028] During specific implementation, as Figure 1 shown, an outer shell 4 is slidably sleeved on the connecting sleeve 2. A driving ring 41 is integrally arranged in the inner cavity of the outer shell 4. The pin holes 21 are located on the moving path of the driving ring 41. When the driving ring 41 is aligned with the pin holes 21, one end of the locking pin 22 extends into the inner cavity of the connecting sleeve 2. The inner diameter formed by one ends of a plurality of locking pins 22 away from the driving ring 41 is smaller than the outer diameter of the boss 11. When the connecting sleeve 2 is connected to the pipe orifice 1, after the locking pins 22 move towards the axis and abut against one end of the boss 11, the driving ring 41 moves to the pin holes 21 to limit the return of the locking pins 22, so that a plurality of locking pins 22 maintain a fixed position. Even after the screw rod 32 drives the plug seat 31 to dock with the pipe orifice 1 subsequently, the locking pins 22 still always abut against the boss 11, thereby providing support for the driving of the screw rod 32.

[0029] More specifically, as Figure 1As shown in the figure, the locking pin 22 is a steel ball. One end of the pin hole 21 close to the axis is conical, which can make a part of the steel ball protrude from the pin hole 21. At the same time, when the steel ball is at the bottom of the pin hole 21, its upper end driving ring 41 abuts, and then restricts the separation of the connecting sleeve 2 from the pipe orifice 1 by abutting the steel ball against the boss 11. At the same time, a snap ring 23 is sleeved on the connecting sleeve 2 at one end of the pin hole 21 away from the screw 32. The outer diameter of the snap ring 23 is greater than the inner diameter of the driving ring 41, thereby preventing the driving ring 41 and the outer shell 4 from detaching from the connecting sleeve 2. When the driving ring 41 abuts against the snap ring 23, the driving ring 41 is aligned with the pin hole 21. Then, by abutting the driving ring 41 against the snap ring 23, the driving ring 41 can be quickly aligned with the pin hole 21 and at the same time abut against the steel ball. The efficiency of locking the boss 11 by several steel balls can be improved. A slope 42 is provided at one end of the driving ring 41 close to the snap ring 23. When the driving ring 41 moves towards the snap ring 23, the steel ball can be conveniently pushed deep into the pin hole 21 through the slope 42, which helps the steel ball to move towards the axis to lock the boss 11.

[0030] As Figure 1 shown, it further includes a return spring 24. The return spring 24 is sleeved on the connecting sleeve 2. A ring-shaped stepped platform 25 is provided at one end of the connecting sleeve 2 close to the screw 32. The two ends of the return spring 24 respectively abut against the stepped platform 25 and the driving ring 41. During specific implementation, before docking, first move the outer shell 4 towards the screw 32 side, so that the driving ring 41 is separated from several pin holes 21 and does not abut against the steel balls. At this time, the return spring 24 will be compressed. At the same time, align the connecting sleeve 2 with the pipe orifice 1. Until the boss 11 of the pipe orifice 1 passes over several steel balls, during the process of the boss 11 passing over the steel balls, the steel balls will be pushed outwards. The steel balls are restricted by the outer shell 4 and will not completely detach from the pin holes 21. Then release the outer shell 4. Under the action of the return spring 24, push the outer shell 4 to move away from the screw 32 side on the connecting seat. Subsequently, the driving ring 41 pushes the steel balls back into the pin seat through the slope 42 until the driving ring 41 abuts against the snap ring 23. At this time, the inner wall of the driving ring 41 is also aligned with the pin hole 21, and the steel balls are located at the bottom of the pin hole 21. The inner cavity diameter formed between several steel balls is smaller than the outer diameter of the boss 11. Then, when the screw 32 is rotated and the plug seat 31 and the sealing gasket 33 abut against the pipe orifice 1, the steel balls abut against one end of the boss 11, so that the connecting seat does not separate from the pipe orifice 1, thereby providing a reaction force for the screw 32 and making the plug seat 31 and the sealing gasket 33 closely dock with the pipe orifice 1. During subsequent separation, first loosen the screw 32 to separate the plug seat 31 and the sealing gasket 33 from the pipe orifice 1, and then drive the outer shell 4 towards the screw 32 side. When the driving ring 41 is separated from the steel balls, the steel balls move outwards and separate from the boss 11, thereby separating the connecting sleeve 2 from the pipe orifice 1. Through the above method, the pipe orifice 1 can be quickly blocked and loosened, greatly improving the blocking efficiency, with good blocking effect, less loss of the sealing gasket 33, and can be reused multiple times, reducing cost waste.

[0031] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
