Description

Technical Field

[0001] The invention relates to the technical field of building drainage and diversion, and in particular to a quick-install drainage pipe joint and a drainage and diversion device thereof. Background Art

[0002] As the name suggests, the diversion device separates the water flow and changes the amount and direction of the water flow. Diversion devices of different shapes have different functions and are located in different places.

[0003] The diversion device achieves the diversion effect by connecting a single main pipe to multiple branch pipes. When in use, the drain pipe needs to be connected to the main pipe. In the prior art, the two are generally connected by a flange and sealed with a gasket or glue. The tightening of the bolts is cumbersome and the disassembly and assembly are not convenient. Although a buckle-type joint is designed in the prior art, it realizes the clamping of the drain pipe and the main pipe through an elastic buckle. In order to make the clamping of the drain pipe and the main pipe firm, the buckle often has a certain rigidity. Since the joints in the prior art are all fixed at one end and the buckle on the other side is unidirectionally inserted into the fixed end, it is bound to lead to the need for manual labor to provide a large tightening force, and the installation is time-consuming and labor-intensive, which is still not inconvenient enough. Summary of the invention

[0004] In view of the deficiencies in the prior art, the first object of the present invention is to provide a quick-install drainage pipe connector, which solves the problem that the drainage connector in the prior art is still not convenient to install.

[0005] According to an embodiment of the present invention, a quick-install drainage pipe connector includes:

[0006] General Manager,

[0007] A connecting sleeve, the connecting sleeve is arranged on one end of the main pipe and the two are fixedly connected;

[0008] A locking rod, the locking rod is elastically connected to the inner wall of the connecting sleeve along the axial direction of the connecting sleeve, a locking groove is fixedly provided at one end of the locking rod located in the connecting sleeve, and an elastic buckle is also fixedly provided on the end, and the buckle matches the clamping hole on the inner wall of the drain pipe;

[0009] A locking block, wherein the locking block is elastically connected to the connecting sleeve along the radial direction of the connecting sleeve through a connecting module;

[0010] And a driving block, the driving block is opposite to the end face of the drain pipe, the driving block is movably connected to the connecting sleeve along the axial direction of the connecting sleeve, and the driving block has a wedge surface, and the wedge surface can move relative to the locking block to make the locking block disengage from the locking groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] Align the drain pipe and insert it into the connecting sleeve. During this process, the end face of the drain pipe drives the driving block to move axially along the connecting sleeve, so that its wedge-shaped surface moves relative to the locking block. During this process, the locking block moves axially away from the locking groove along the connecting sleeve until it disengages from the locking groove. At this time, the locking rod is unlocked, and under the drive of elastic force, the locking rod axially inserts into the drain pipe along the connecting sleeve until the buckle on the locking rod inserts into the preset card hole on the inner wall of the drain pipe; With the above solution, on the one hand, an external force drives the drain pipe to be inserted into the connecting sleeve, and on the other hand, the locking rod unlocked by the drain pipe inserts into the drain pipe, that is, the buckle and the card hole move towards each other, so that the buckle can be more conveniently and quickly clamped in the card hole, saving time and effort.

[0013] The second object of the present invention is to provide a drainage and diversion device, which solves the problem that the installation of the main pipe and the drain pipe in the existing drainage and diversion device is still not convenient enough.

[0014] According to an embodiment of the present invention, a drainage and diversion device includes: a main body, a branch pipe, and the quick-install water pipe joint as described above. Among them, the main body has a cavity, and the main pipe, the main body, and the branch pipe are communicated in sequence.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Since the drainage and diversion device adopts the above-mentioned quick-install water pipe joint, it can also quickly and conveniently connect the drain pipe firmly to the connecting sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0023] The technical solutions in the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] The present invention proposes an embodiment, such as Figure 1 and Figure 4 shown, a quick-installation drain pipe joint, comprising:

[0025] Main pipe 1,

[0026] Connecting sleeve 2, wherein, the connecting sleeve 2 is provided with a side wall, and the side wall of the connecting sleeve 2 is sleeved on one end of the main pipe 1 and the two are fixedly connected. If the connecting sleeve 2 and the main pipe 1 are made of PVC, they can be heated and welded. If they are made of metal, they can be directly welded. The connecting sleeve 2 and the main pipe 1 are coaxial and communicate with each other;

[0027] Locking rod 3, one end of the locking rod 3 passes through the baffle 16 of the connecting sleeve 2 along the axial direction of the connecting sleeve 2 and there is a clearance fit between them. Two limiting disks are fixedly arranged on the locking rod 3. The limiting disk located at the rightmost end of the locking rod 3 is used to prevent the locking rod 3 from sliding out to the left. An elastic element is arranged between the other limiting disk and the side wall of the connecting sleeve 2. In this embodiment, the elastic element is further described as a cylindrical spring. The cylindrical spring is sleeved on the locking rod 3, and the two ends of the cylindrical spring respectively abut against the side wall of the connecting sleeve 2 and one of the limiting disks to realize the elastic connection between the locking rod 3 and the connecting sleeve 2; A locking groove 301 is fixedly arranged at one end of the locking rod 3 located inside the connecting sleeve 2, and an elastic buckle 302 is also fixedly arranged on this end. The locking groove 301 in this embodiment is a semi-circular groove, and the buckle 302 is triangular and its inclined surface faces the drain pipe, so that the buckle 302 can be smoothly inserted into a preset hole (not shown in the figure) on the inner wall of the drain pipe;

[0028] Locking block 4, the locking block 4 is elastically connected to the connecting sleeve 2 along the radial direction ( Figure 4 the vertical direction) of the connecting sleeve 2 through a connecting module;

[0029] And a driving block 5, the end face of the driving block 5 facing the drain pipe, one end of the driving block 5 passes through the other inner wall of the connecting sleeve 2 along the axial direction of the connecting sleeve 2 and there is a clearance fit between them. A round table is fixedly arranged at the other end of the driving block 5 and the small end of the round table faces the drain pipe. A spring arranged along the axial direction of the connecting sleeve 2 is arranged between the large end of the round table and the inner wall of the connecting sleeve 2. The side wall of the round table forms a wedge surface, and the wedge surface can slide relative to the locking block 4 to make the locking block 4 disengage from the locking groove 301; Only the upper and lower two buckles 302 are shown in this embodiment. To ensure the connection stability between the drain pipe and the main pipe 1, it is of course possible to set more buckles 302.

[0030] Align the drain pipe and insert it rightward into the connecting sleeve 2. During this process, the end face of the drain pipe drives the driving block 5 to move rightward along the axial direction of the connecting sleeve 2, so that its wedge-shaped surface moves relative to the locking block 4, causing the locking block 4 to move upward until it disengages from the locking groove 301. At this time, the locking rod 3 is inserted into the drain pipe along the axial direction of the connecting sleeve 2 under the drive of the spring until the buckle 302 on the locking rod 3 is inserted into the preset card hole in the inner wall of the drain pipe; with the above solution, on the one hand, an external force drives the drain pipe to be inserted into the connecting sleeve 2, and on the other hand, the locking rod 3 unlocked by the drain pipe moves leftward under the action of the elastic force and is inserted into the drain pipe, that is, the buckle 302 and the card hole move towards each other, so that the buckle 302 can be more conveniently and quickly clamped in the card hole, saving time and effort.

[0031] Another embodiment of the present invention is proposed, as Figure 1 shown, further comprising:

[0032] An expansion adsorbent 6 fixedly arranged on the inner wall of the connecting sleeve 2, which can adsorb moisture and expand when heated. For example, it can be an existing water-absorbing expansion strip, and of course, it can also be other existing materials that can expand after being heated and absorbing water;

[0033] And a heating module, which is installed on the connecting sleeve 2 to heat the expansion adsorbent 6. In this embodiment, taking the condenser plate 7 as an example of the heating module, the condenser plate 7 is fixed on the outer wall of the connecting sleeve 2, and the condenser plate 7 faces the outer wall of the connecting sleeve 2 to refract light to the outer wall of the connecting sleeve 2. The condenser plate 7 can be selected from existing convex lenses or condensers.

[0034] The condenser plate 7 condenses and refracts light to the outer wall of the connecting sleeve 2 to heat the expansion adsorbent 6 inside it. The expansion adsorbent 6 expands when heated to seal the connection between the connecting sleeve 2 and the drain pipe. On the other hand, if water overflows at the above connection, the expansion adsorbent 6 absorbs water and expands to further seal the connection between the connecting sleeve 2 and the drain pipe, ensuring the sealing effect.

[0035] Another embodiment of the present invention is proposed, as Figure 1 and Figure 4As shown in the figure, the connection module includes a telescopic rod 8. The telescopic rod 8 includes a coaxial fixed cylinder and a telescopic part. One end of the telescopic part is inserted into the fixed cylinder, and the two are elastically connected by a spring. One end of the fixed cylinder is fixedly arranged on the inner wall of the connection sleeve 2. A roller 9 that can roll along the wedge surface is rotatably connected to the middle of the telescopic part. The lock block 4 is installed at the bottom end of the telescopic part. To reduce frictional losses, in this embodiment, the lock block 4 is set as a round wheel rotatably connected to the bottom end of the telescopic part. It should be understood that in order to enable the telescopic rod 8 to smoothly drive the lock block 4 to move upward, the telescopic rod 8 and the wedge surface are distributed in a front-back offset manner, while the roller 9 is rotatably connected to one side of the telescopic rod 8 to ensure that the roller 9 is always in rolling contact with the wedge surface. When the wedge surface moves to the right, the above setting enables the telescopic rod 8 to smoothly drive the lock block 4 to move upward until it disengages from the lock groove 301.

[0036] The present invention also proposes another embodiment. As Figures 1 to 3 shown, a drainage and diversion device includes: a main body 10, a branch pipe 11, and the above-mentioned quick-install water pipe joint. Among them, the main body 10 has a cavity. There are two branch pipes 11. The main pipe 1, the main body 10, and the branch pipes 11 are connected in sequence. In practice, in order to enable the branch pipes 11 to be conveniently connected to the branch pipes 11, the connection structure of the two branch pipes 11 is also set to be the same as that of the main pipe 1, and details thereof will not be elaborated here.

[0037] Since the drainage and diversion device adopts the above-mentioned quick-install water pipe joint, it can also quickly and conveniently connect the drain pipe firmly to the connection sleeve 2.

[0038] The present invention proposes another embodiment. As Figures 1 to 3 shown, it further includes: a filter screen 12 fixedly arranged in the main body 10. The filter screen 12 is opposite to the inlet of the main pipe 1 entering the main body 10 to filter impurities.

[0039] Two upper and lower cutters 13 that can be engaged with each other. One of the cutters 13 is movably connected in the main body 10 along the radial direction of the main pipe 1 and is in contact with the mesh surface of the filter screen 12.

[0040] And a driving module. The driving module is connected to one of the cutters 13 to drive the cutter 13 to move towards the other cutter 13. When the driving module drives one of the cutters 13 to move downward along the filter screen 12, the impurities on the filter screen 12 can be scraped off. When the two cutters 13 are engaged with each other, the impurities are cut off, and the small impurities are made convenient to pass through the filter screen 12 and will not block the pipeline.

[0041] The present invention proposes another embodiment. As Figures 1 to 3 shown, the driving module includes:

[0042] A screw rod 14 whose upper and lower ends are rotatably connected in the main body 10.

[0043] A plurality of blades 15 fixedly arranged on the screw rod 14, each blade 15 is distributed on the circumferential side of the screw rod 14, and the included angle between the blade 15 and the screw rod 14 should be set reasonably so that the fluid gushing out from the main pipe 1 or the branch pipe 11 can impact the blade 15 along the tangential direction of the screw rod 14, thereby driving the screw rod 14 to rotate by the blade 15. A nut is sleeved on and threadedly connected to the screw rod 14, and the nut is fixedly connected to one of the cutting tools 13 through a connecting rod. Of course, the nut should be sleeved on the vertical guide rod to prevent the nut from rotating with the screw rod 14. By switching the water inlet of the main pipe 1 or the branch pipe 11, on the one hand, the screw rod 14 can be rotated forward or backward, thereby driving one of the cutting tools 13 to move upward or downward; on the other hand, the impurities on the filter screen 12 can also be backwashed.

[0044] Another embodiment of the present invention is proposed, as Figure 3 and Figure 5 shown, one end of the branch pipe 11 is inserted into the main body 10 and a baffle 16 for closing the branch pipe 11 is movably connected to the end along its radial direction. A floating ball 17 for driving the baffle 16 to move is fixedly arranged on the baffle 16; as the liquid in the main body 10 increases, the floating ball 17 floats upward and pulls the baffle 16 to move together; the position of the baffle 16 can be adaptively adjusted by the floating ball 17 according to the liquid level height in the main body 10, so as to realize the adjustment of the flow rate of the branch pipe 11.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
