Description

Technical Field

[0001] The invention belongs to the technical field of water discharge, and relates to a pull-type water discharger and a water stopper for the pull-type water discharger. Background Art

[0002] A pull-up type water discharger is a type of water discharger, which opens or closes the water discharger by a pull-up action. For example, a water discharger disclosed in patent application number 201520232836.4 includes a water discharge pipe, a water discharge plug located at the upper end of the water discharge pipe, a connecting piece connected to the lower end of the water discharge plug, the connecting piece is connected to the pull-up device through a joint bearing, a transverse bearing tube is provided on one side of the water discharge pipe, and the joint bearing is located at the end of the bearing tube; wherein, the bearing joint is composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, the outer ring is threadedly sealed with the bearing tube, the pull-up device is composed of a connecting rod and a pull-up rod connected by a clamp and a positioning plate, one end of the connecting rod is movably connected to the connecting piece through a joint bearing, the upper end of the connecting piece is threadedly connected to the water discharge plug, the connecting piece has four blades connected to the inner wall of the water discharge pipe, and the lower end of the connecting piece is provided with a connecting hole through which the connecting rod can pass. When in use, the upper and lower pulling rods drive the connecting rod to drive the connecting piece to move up and down through the lever effect of the joint bearing, so that the drain plug can be closed or opened.

[0003] After long-term use, the lower end of the connector is prone to excessive wear and failure to fit the lifting device. In this case, the connector needs to be replaced. Since the connecting rod passes through the connector, in order to remove the connector from the sewer pipe for replacement, it is necessary to first remove the connecting rod from the connecting hole of the connecting rod, which means that the connection between the connecting rod and the lifting rod must be disconnected first, and then the outer ring must be unscrewed from the bearing tube to release the fixing of the connecting rod. It can be seen that the replacement involves the disassembly of multiple parts, among which the outer ring is not difficult to operate because it is threadedly connected to the bearing tube, but the connecting rod and the lifting rod are connected by a positioning plate and a clamping clamp, which makes the disassembly and reconnection here particularly complicated, resulting in the problem of inconvenient replacement of the above-mentioned drain.

[0004] Because the disassembly between the connecting rod and the lifting rod is relatively complicated and is the key factor causing the inconvenience in replacing the connecting parts, it is conventionally easier to think of improving the convenience of disassembly between the connecting rod and the lifting rod, just like a water discharger disclosed in patent application No. 201620346147.8, which simplifies the connection between the connecting rod and the lifting rod so that the two can be quickly disassembled. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems existing in the prior art, and to propose a pull-type drain and a water stopper for the pull-type drain, so as to solve the problem of inconvenient replacement.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A pull-type water discharger comprises a water discharge body, a water stop plug inserted in the water discharge body, a horizontal connecting rod with an inner end inserted into the water discharge body, and a vertical pull rod linked to the outer end of the horizontal connecting rod. The water stop plug comprises a connecting piece and a sealing head fixedly connected to the top end of the connecting piece. The connecting piece is characterized in that a bayonet is provided at the lower part of the connecting piece, the bayonet is vertically elongated and passes through the bottom of the connecting piece, a plurality of slots are vertically provided on the inner wall of the bayonet, the connecting piece is plugged onto the outside of the inner end of the horizontal connecting rod through the bayonet, and the inner end of the horizontal connecting rod is stuck in one of the slots.

[0008] The connecting piece is inserted into the inner end of the horizontal connecting rod through the bayonet and the inner end of the horizontal connecting rod is stuck in one of the slots, so that the water stop plug is connected to the inner end of the horizontal connecting rod. When the user pulls up the vertical pull rod, the inner end of the horizontal connecting rod will drive the water stop plug to move downward, so that the sealing head rests against the upper end of the drain body to form a seal, so that the basin can store water; when the user presses down the vertical pull rod, the inner end of the horizontal connecting rod will drive the water stop plug to move upward, so that the sealing head is separated from the upper end of the drain body, so that the basin can drain water. When the water stopper needs to be replaced after a long period of use, because the bayonet penetrates the bottom of the connecting piece, the user only needs to pull the old water stopper upwards. During this process, the cross-link rod will squeeze the inner wall of the bayonet to stretch it open, so that the old water stopper will eventually be disengaged from the cross-link rod. After that, the user only needs to insert the new water stopper into the main body of the water discharger. The bayonet of the connecting piece in the new water stopper will be stretched open by the cross-link rod and can be inserted outside the cross-link rod until the inner end of the cross-link rod is stuck in the slot provided on the inner wall of the bayonet. The bayonet setting allows the user to directly replace the water stopper without disassembling the cross-link rod, which greatly improves the convenience of replacement.

[0009] In addition, in practice, when installing on different wash basins, the vertical position of the horizontal connecting rod will vary. The bayonet is vertically strip-shaped, and the number of slots on the inner wall of the bayonet is several in the vertical direction. This arrangement allows the connector of the water stopper to form a reliable fit with the horizontal connecting rods at different positions in the vertical direction, ensuring stability, and also preventing eccentric wear between the connector and the horizontal connecting rod.

[0010] In the above-mentioned pull-up drain, the lower end of the bayonet is trumpet-shaped.

[0011] The inner end of the cross-linking rod is located inside the launch body and cannot be seen directly with the naked eye when the water stop plug is matched with the cross-linking rod. Therefore, the lower end of the bayonet is set to be trumpet-shaped. In this way, even if the bayonet and the side of the cross-linking rod are not directly facing each other when the water stop plug is inserted, the user only needs to slightly turn the water stop plug to directly slide the cross-linking rod into the lower end of the bayonet, further improving the convenience of replacement.

[0012] In the above-mentioned pull-type drain, the lower part of the connecting piece is in the shape of a flat long plate along the vertical direction, the thickness direction of the connecting piece is the axial direction of the horizontal connecting rod, and the bayonet is arranged along the thickness direction of the connecting piece.

[0013] The lower part of the connecting piece is in the shape of a long plate in the vertical direction, and combined with the setting of the long strip-shaped bayonet, the lower part of the entire connecting piece is like an elastic clip, which can firmly clamp the connecting piece when it is inserted into the inner end of the horizontal connecting rod through the bayonet.

[0014] In the above-mentioned pull-type drain, the width of the lower part of the connecting piece gradually decreases from top to bottom.

[0015] The lower width of the connecting piece gradually decreases from top to bottom, which means that when there is a bayonet, the closer to the bottom the position, the stronger the deformation ability is, making it easier for the cross-link to squeeze into or out of the bayonet, further improving the convenience of replacement.

[0016] In the above-mentioned pull-up drain, the pull-up drain also includes a filter screen in the shape of a cylinder with an open upper end, the upper part of the connecting piece has a plurality of guide blades, the filter screen is sleeved outside the upper part of the connecting piece, the bottom of the filter screen is provided with a clearance port, and the lower part of the connecting piece passes through the clearance port.

[0017] By sleeved a filter net in the shape of a cylinder with an upper opening on the outside of the upper part of the connecting piece, hair and the like can be filtered when the pull-type drain is in a discharge state.

[0018] However, as mentioned in the background technology, in the existing pull-up drain, the horizontal connecting rod and the water stop plug are matched by perforations, and the water stop plug is very inconvenient to disassemble, and the filter net needs to be taken out for cleaning every few days. If the filter net is to be taken out, the water stop plug must be removed. Therefore, it is not conventional to set a filter net in the pull-up drain for filtering. In the present pull-up drain, on the basis that the water stop plug can be directly pulled out for disassembly and installation, the filter net is put on the upper part of the connecting piece of the water stop plug, so that when the water stop plug is directly pulled out using the bayonet at the bottom of the connecting piece, the filter net can be taken out together, which greatly improves the convenience of users to remove and clean the filter net.

[0019] In the above-mentioned pull-type drain, there are two guide blades, which intersect in a cross shape, wherein the thickness of the lower part of one of the guide blades gradually increases and the bottom of the filter screen abuts against the lower part of the guide blade.

[0020] By setting the lower thickness of one of the guide blades to gradually increase, such a structure provides a position for the bottom of the filter to rest so that the bottom of the filter can rest on the lower part of the guide blade, so that when the water stop plug is directly pulled out, the filter can be taken out together to facilitate the user to clean the filter.

[0021] In the above-mentioned pull-type drain, the side of the filter screen is provided with a clearance gap corresponding to the guide blade along the circumferential direction, the clearance gap is vertically strip-shaped, and the guide blade passes through the clearance gap.

[0022] By setting the clearance gap, the guide blade can be free from the obstruction of the filter screen and can still form a normal guiding match with the launch body.

[0023] In the above-mentioned pull-type drain, the connecting part includes a main body and an insert, the main body is a plastic part, the insert is a thermoplastic elastic part, the lower part of the main body is an inverted U-shape, the insert is an inverted U-shape, the insert is fixedly connected to the inner side of the lower part of the main body, the lower end of the bayonet is located on the main body, and the rest of the bayonet is located on the insert.

[0024] In actual production, the main body is produced first, and then the main body is placed in a mold and an insert is formed on it, thereby obtaining a connector, and the lower end of the bayonet is on the main body, and the rest of the bayonet is on the insert. The main body of the connector is a plastic part, which has a certain hardness to ensure that the guide blades and the main body of the launch can form a reliable guide fit, and the insert is a thermoplastic elastomer, which has better elasticity than plastic. It cooperates with the cross-link to increase the damping feeling, ensure the connection stability between the water stop plug and the cross-link, and ensure that the water stop plug can be stably driven to move when the cross-link swings. At the same time, it can also maintain a good clamping force when the water stop plug is in a long-term open state or after repeated insertion and removal.

[0025] The water stopper of a pull-type drain comprises a connecting piece and a sealing head fixedly connected to the top of the connecting piece, wherein the upper part of the connecting piece has a plurality of guide blades along the circumferential direction, and is characterized in that a bayonet is provided at the lower part of the connecting piece, the bayonet is vertically elongated and passes through the bottom of the connecting piece, and the inner wall of the bayonet is vertically provided with a plurality of slots.

[0026] When connecting the water stop plug to the horizontal connecting rod of the pull-type water discharger, the user only needs to insert the water stop plug into the water discharge body, because the lower part of the connecting piece is provided with a bayonet and the bayonet runs through the bottom of the connecting piece, so that the connecting piece of the water stop plug can be directly plugged into the inner end of the horizontal connecting rod. During the plugging process, the outer wall of the inner end of the horizontal connecting rod will open the bayonet until the inner end of the horizontal connecting rod is stuck in the slot of the inner wall of the bayonet, so that the horizontal connecting rod and the water stop plug are firmly connected together. When the water stop plug needs to be replaced, the user only needs to pull the water stop plug upwards. During this process, the horizontal connecting rod will squeeze the inner wall of the bayonet to open it and finally disengage the water stop plug from the horizontal connecting rod. Through the setting of the bayonet, the user can directly replace the water stop plug without disassembling the horizontal connecting rod, which greatly improves the convenience of replacement.

[0027] In addition, in practice, when installing on different wash basins, the vertical position of the horizontal connecting rod will vary. The bayonet is vertically strip-shaped, and the number of slots on the inner wall of the bayonet is several in the vertical direction. This arrangement allows the connector of the water stopper to form a reliable fit with the horizontal connecting rods at different positions in the vertical direction, ensuring stability, and also preventing eccentric wear between the connector and the horizontal connecting rod.

[0028] Compared with the prior art, the present pull-up drain has a bayonet at the lower part of the connecting piece, the bayonet is vertically elongated and a slot is vertically arranged on the inner wall of the bayonet, so that the water stop plug and the cross-connecting rod are connected in such a way that the bayonet is inserted on the outside of the inner end of the cross-connecting rod and the inner end of the cross-connecting rod is stuck in one of the slots. Such a connection structure ensures that the user can directly replace the water stop plug by plugging and pulling without disassembling the cross-connecting rod, thereby greatly improving the convenience of replacement.

DETAILED DESCRIPTION

[0038] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0039] Embodiment 1

[0040] like Figure 1 , Figure 2 and Figure 3As shown, the pull-up water discharger comprises a water discharge body 1, a water stopper 2 inserted in the water discharge body 1, a horizontal connecting rod 3 with an inner end inserted into the water discharge body 1, and a vertical pull rod 4 linked with the outer end of the horizontal connecting rod 3. The water discharge body 1 comprises an upper connecting body 7 and a lower connecting body 8 both in a cylindrical shape, the lower connecting body 8 is threadedly connected to the lower end of the upper connecting body 7, and a port 8b is protrudingly provided on the side of the lower connecting body 8, and the horizontal connecting rod 3 penetrates into the lower connecting body 8 from the port 8b. An upper annular abutment portion 7a is provided on the outer side of the upper end of the upper connecting body 7, and a lower annular abutment portion 8a is provided on the outer side of the upper end of the lower connecting body 8. When installing, after the lower end of the upper connecting body 7 is passed through the hole at the bottom of the wash basin, the lower connecting body 8 is threadedly connected to the lower end of the upper connecting body 7, so that the upper annular abutment portion 7a will abut against the inner bottom wall of the wash basin and the lower annular abutment portion 8a will abut against the bottom of the wash basin, thereby making the water discharge body 1 installed and fixed on the wash basin. Furthermore, in order to ensure that there is no water leakage between the water discharge main body 1 and the wash basin after installation, an upper sealing gasket 9 can be connected to the outer sleeve of the upper connector 7 and the upper annular abutment portion 7a can press the upper sealing gasket 9 against the inner bottom wall of the wash basin, and a lower sealing gasket 10 can be connected to the outer sleeve of the lower connector 8 and the lower annular abutment portion 8a can press the lower sealing gasket 10 against the bottom of the wash basin. The horizontal connecting rod 3 has a spherical matching portion 3a near the inner end, and the matching portion 3a is located in the interface 8b. Two supporting rings 11 are arranged in the interface 8b. The two supporting rings 11 are located on both sides of the matching portion 3a and the matching portion 3a forms a spherical match with the two supporting rings 11. The interface 8b is externally threaded with a locking cap 12 to position the two supporting rings 11 in the locking cap 12 in the interface 8b. The spherical match enables the horizontal connecting rod 3 to swing up and down with this as the fulcrum. The water stopper 2 includes a connector 5 and a sealing head 6 fixedly connected to the top of the connector 5. The upper part of the connector 5 has a plurality of guide blades 5a along the circumferential direction. The connector 5 forms a guide match with the launch body 1 through each guide blade 5a. The number of guide blades 5a is two, and the two guide blades 5a intersect to form a cross shape. A locking block 13 is fixed to the outer end of the horizontal connecting rod 3. The locking block 13 is provided with a socket. The lower end of the vertical tie rod 4 passes through the socket. The side of the locking block 13 is threadedly connected with a locking screw 14. The end of the locking screw 14 presses against the side of the vertical tie rod 4, thereby fixing the vertical tie rod 4 and the horizontal connecting rod 3 together, so that the horizontal connecting rod 3 can be driven to swing when the vertical tie rod 4 moves up and down.

[0041] like Figure 2 , Figure 3 and Figure 4As shown, the lower part of the connecting member 5 is provided with a bayonet 5b, which is in the shape of a long strip in the vertical direction and runs through the bottom of the connecting member 5, and the lower end of the bayonet 5b is in the shape of a trumpet. The inner wall of the bayonet 5b is provided with a plurality of slots 5c in the vertical direction, and the connecting member 5 is plugged into the inner end of the horizontal connecting rod 3 through the bayonet 5b, and the inner end of the horizontal connecting rod 3 is stuck in one of the slots 5c. The slot 5c is an arc-shaped slot, and the slot wall of the slot 5c and the inner wall of the bayonet 5b are transitioned through an arc. The connecting piece 5 is inserted into the inner end of the transverse connecting rod 3 through the bayonet 5b and the inner end of the transverse connecting rod 3 is stuck in one of the slots 5c, so that the water stop plug 2 is connected to the inner end of the transverse connecting rod 3. When the user pulls up the vertical pull rod 4, the inner end of the transverse connecting rod 3 will drive the water stop plug 2 to move downward, so that the sealing head 6 abuts against the upper end of the water discharge body 1 to form a seal, so that the washbasin can store water; when the user presses down the vertical pull rod 4, the inner end of the transverse connecting rod 3 will drive the water stop plug 2 to move upward, so that the sealing head 6 is separated from the upper end of the water discharge body 1, so that the washbasin can drain water. When the water stopper 2 needs to be replaced after a long period of use, because the bayonet 5b runs through the bottom of the connecting piece 5, the user only needs to pull the old water stopper 2 upwards. In this process, the cross connecting rod 3 will squeeze the inner wall of the bayonet 5b to open it and finally disengage the old water stopper 2 from the cross connecting rod 3. After that, the user only needs to insert the new water stopper 2 into the main body 1. The bayonet 5b of the connecting piece 5 in the new water stopper 2 will be opened by the cross connecting rod 3 and inserted outside the cross connecting rod 3 until the inner end of the cross connecting rod 3 is stuck in the slot 5c provided on the inner wall of the bayonet 5b. The setting of the bayonet 5b allows the user to directly replace the water stopper 2 without disassembling the cross connecting rod 3, which greatly improves the convenience of replacement. The inner end of the cross-linking rod 3 is located inside the launching body 1 and cannot be seen directly with the naked eye when the water stop plug 2 is matched with the cross-linking rod 3. Therefore, the lower end of the bayonet 5b is set to be trumpet-shaped. In this way, even if the bayonet 5b and the side of the cross-linking rod 3 are not directly facing each other when the water stop plug 2 is inserted, the user only needs to slightly turn the water stop plug 2 to directly slide the cross-linking rod 3 into the lower end of the bayonet 5b, thereby further improving the convenience of replacement.

[0042] In addition, in practice, when installing on different wash basins, the vertical position of the horizontal connecting rod 3 will vary. The bayonet 5b is vertically long and the number of the slots 5c on the inner wall of the bayonet 5b is several in the vertical direction. Such a setting can make the connecting piece 5 of the water stopper 2 form a reliable match with the horizontal connecting rod 3 at different positions in the vertical direction, ensuring stability, and also preventing the eccentric wear between the connecting piece 5 and the horizontal connecting rod 3.

[0043] In this embodiment, if Figure 3 and Figure 4As shown, the lower part of the connecting member 5 is in the shape of a flat long plate in the vertical direction, the lower part of the connecting member 5 is connected to the bottom of one of the guide blades 5a, and the thickness direction of the lower part of the connecting member 5 is the same as the thickness direction of the guide blade 5a, the thickness direction of the connecting member 5 is the axial direction of the transverse connecting rod 3, and the bayonet 5b is arranged along the thickness direction of the connecting member 5, that is, the bayonet 5b penetrates both sides of the connecting member 5 along the thickness direction. The width of the lower part of the connecting member 5 decreases from top to bottom, and the gradually decreasing width means that the closer to the lower position in the case of the bayonet 5b, the stronger the deformation ability, so that the transverse connecting rod 3 can be squeezed into the bayonet 5b or disengaged from the bayonet 5b more easily, further improving the convenience of replacement.

[0044] Embodiment 2

[0045] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that: in this embodiment, Figure 5 , Figure 6 and Figure 7 As shown, the pull-up drain also includes a filter screen 15 in the shape of a cylinder with an upper opening, the filter screen 15 is sleeved outside the upper part of the connecting member 5, and a clearance port 15a is provided at the bottom of the filter screen 15, and the lower part of the connecting member 5 passes through the clearance port 15a. By sleeved the filter screen 15 in the shape of a cylinder with an upper opening outside the upper part of the connecting member 5, hair and the like can be filtered when the pull-up drain is in a discharge state. The thickness of the lower part of one of the guide blades 5a gradually increases (the guide blade 5a is the one connected to the lower part of the connecting member 5), and the bottom of the filter screen 15 abuts against the lower part of the guide blade 5a. By setting the thickness of the lower part of one of the guide blades 5a to gradually increase, such a structure provides a position for the bottom of the filter screen 15 to abut against, so that the bottom of the filter screen 15 can abut against the lower part of the guide blade 5a, so that when the water stopper 2 is directly pulled out, the filter screen 15 can be taken out together to facilitate the user to clean the filter screen 15.

[0046] Further, the side of the filter 15 is provided with a clearance notch 15b corresponding to the guide blade 5a along the circumferential direction, and the clearance notch 15b is strip-shaped along the vertical direction, and the guide blade 5a passes through the clearance notch 15b. The filter 15 gradually becomes smaller from top to bottom, and the filter 15 between two adjacent clearance notches 15b is in the shape of a spring sheet, and the upper port of the upper connector 7 in the water discharge main body 1 is in the shape of an outward expansion. When the present pull-up water discharger is in the open state, the upper part of the filter 15 is located in the upper port of the upper connector 7, and the upper outer wall of the filter 15 is against the inner wall of the upper port of the upper connector 7. When the user pulls up the vertical pull rod 4, the inner end of the horizontal connecting rod 3 will drive the water stopper 2 to move downward, and the filter 15 will move downward together with the water stopper 2. Since the filter 15 gradually becomes smaller from top to bottom and the filter 15 between two adjacent clearance notches 15b is in the shape of a spring sheet, the filter 15 will shrink under the action of the inner wall of the upper connector 7 during this process.

[0047] Embodiment 3

[0048] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that: Figure 8 As shown, in this embodiment, specifically, the connector 5 includes a body 5d and an insert 5e, the body 5d is a plastic part, the insert 5e is a thermoplastic elastic part, the lower part of the body 5d is inverted U-shaped, the insert 5e is inverted U-shaped, the insert 5e is fixedly connected to the inner side of the lower part of the body 5d, the lower end of the bayonet 5b is located on the body 5d, and the rest of the bayonet 5b is located on the insert 5e. In actual production, the body 5d is first produced, and then the body 5d is placed in a mold to mold the insert 5e thereon, thereby obtaining the connector 5, and the lower end of the bayonet 5b is on the body 5d, and the rest of the bayonet 5b is on the insert 5e. The main body 5d of the connecting piece 5 is a plastic part, which has a certain hardness and can ensure that the guide blade 5a can form a reliable guiding fit with the launching body 1, while the insert 5e is a thermoplastic elastomer, which has better elasticity than plastic. It cooperates with the cross-link 3 to increase the damping feeling, ensure the connection stability between the water stop plug 2 and the cross-link 3, and ensure that the cross-link 3 can stably drive the water stop plug 2 to move when it swings. At the same time, it can also maintain a good clamping force even when the water stop plug 2 is in a long-term open state or after repeated insertion and removal.

[0049] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
