Description

Technical Field

[0001] The utility model relates to the technical field of valve faucets, in particular to a joint for valve faucets which is easy to replace. Background Art

[0002] The valve faucet is the popular name for the gas valve, which is used to control the size of the gas flow switch and has the effect of saving gas. The valve faucet is updated very quickly, from the old cast iron process to the electroplated knob type, and then to the stainless steel single-temperature single-control valve faucet, stainless steel double-temperature double-control faucet, and kitchen semi-automatic faucet. The valve faucet joint is an important component on the valve faucet, which plays an important role in connecting the valve faucet and the gas pipe.

[0003] For example, Chinese patent authorization announcement No. CN 220151983 U discloses an exhaust valve joint, including a lower connecting seat, the upper end face of the lower connecting seat is fixedly connected to the upper connecting seat, the inner side wall of the upper connecting seat is provided with an internal thread, the lower end of the inner side wall of the upper connecting seat is fixedly connected to a fixing plate, the upper end face of the fixing plate is fixedly connected to a first spring, a side wall of the upper connecting seat is threadedly connected to a limit bolt, an internal thread is provided on the inner side wall of the upper connecting seat, a first spring is arranged at the upper end of the fixing plate, a third spring is arranged at the lower end face of the lower connecting seat, a pipeline is connected through the internal thread, and an exhaust valve is connected through the external thread, when the pipeline and the exhaust valve are tightened, the first spring and the third spring will exert an outward force on the pipeline and the exhaust valve, increase the friction between the threads of the pipeline, the exhaust valve and the joint, and thus ensure the stability of the connection between the pipeline, the exhaust valve and the joint;

[0004] By referring to the above comparative documents, it can be seen that the prior art still has the following deficiencies: after the joint is installed on the valve faucet, a filter is generally installed inside the joint to filter the gas; however, once the filter is clogged and needs to be replaced, the entire joint often needs to be replaced, resulting in a high replacement cost; and there is a lack of measures to adjust the exhaust angle of the joint, resulting in the exhaust angle of the valve faucet being fixed and unchanged, and therefore not flexible enough to use. Utility Model Content

[0005] The utility model provides a connector which is easy to replace for a valve faucet, which is conducive to conveniently replacing a filter screen, reducing replacement costs, and is conducive to adjusting the exhaust angle of the valve faucet at multiple angles.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A connector for a valve faucet that is easy to replace, comprising an internal thread connection sleeve and an external thread exhaust pipe, wherein the external thread exhaust pipe is arranged below the internal thread connection sleeve;

[0008] A filter is installed in the external thread exhaust pipe, and the upper end of the outer periphery of the external thread exhaust pipe is threadedly connected to an internal thread connecting pipe, the upper end of the inner periphery of the internal thread connecting pipe is rotatably connected to a ball shaft, a vent is passed through the middle of the ball shaft, a guide pipe extending upward from the ball shaft is fixed to the inner wall of the vent, an exhaust port is opened at the lower end of the internal thread connecting sleeve, and the upper end of the outer periphery of the guide pipe is fixed to the inner wall of the exhaust port;

[0009] A plurality of groups of damping and limiting components are arranged on the periphery of the ball shaft.

[0010] Furthermore, a first sealing ring is connected to the upper end of the externally threaded exhaust pipe, and a second sealing ring is provided at the inner lower end of the externally threaded exhaust pipe.

[0011] Furthermore, an inner sealing ring and an outer sealing ring are provided at the connection between the externally threaded exhaust pipe and the internally threaded connecting pipe, wherein the inner sealing ring is located at the upper end of the externally threaded exhaust pipe and the outer sealing ring is located at the lower end of the internally threaded connecting pipe.

[0012] Furthermore, a metal corrugated hose is connected between the internally threaded connecting sleeve and the internally threaded connecting pipe, and the guide tube and the ball shaft are both located in the metal corrugated hose.

[0013] Furthermore, the damping limit assembly is composed of a spring pressure rod and a damping ball, a plurality of contraction grooves are opened at the upper end of the inner wall of the internal threaded connecting tube, the spring pressure rods are connected to the contraction grooves, and the damping balls are connected to the ends of the spring pressure rods.

[0014] Furthermore, the damping ball contacts the outer surface of the ball shaft, and the damping ball is made of rubber material.

[0015] Beneficial effects of the utility model:

[0016] 1. The joint can be conveniently threaded with the valve faucet through the internal thread connection sleeve, and the external thread exhaust pipe is threaded with the internal thread connection pipe, so the external thread exhaust pipe and the filter can be easily disassembled and replaced, and only the external thread exhaust pipe and the filter need to be replaced, without replacing the entire joint, so the replacement cost is low;

[0017] 2. By twisting the internal threaded connecting pipe to swing in all directions along the ball shaft, it is convenient to adjust the exhaust angle of the joint, and also convenient to adjust the exhaust angle of the valve faucet. The elastic force of the spring pressure rod drives the damping ball to press on the outer surface of the ball shaft, which helps to prevent the internal threaded connecting pipe from twisting accidentally, effectively ensuring the stability of the use of the internal threaded connecting pipe after the angle is adjusted, and making the exhaust angle flexible and changeable.

DETAILED DESCRIPTION

[0025] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0026] like Figure 1 , 2 As shown in Figure 5, in this embodiment, it includes an internal threaded connecting sleeve 1 and an external threaded exhaust pipe 3, the external threaded exhaust pipe 3 is arranged below the internal threaded connecting sleeve 1, a filter screen 9 is installed in the external threaded exhaust pipe 3, and the upper end of the outer periphery of the external threaded exhaust pipe 3 is threadedly connected to the internal threaded connecting pipe 2, the upper end of the external threaded exhaust pipe 3 is connected to a first sealing ring 4, and the lower end of the external threaded exhaust pipe 3 is provided with a second sealing ring 5.

[0027] The joint can be conveniently threadedly connected to the externally threaded valve faucet through the internal threaded connecting sleeve 1. During the installation process, the lower end of the valve faucet is inserted into the internal threaded connecting sleeve 1 until the lower end of the valve faucet is pressed tightly against the second sealing ring 5, and the first sealing ring 4 will be sleeved on the outer periphery of the valve faucet. Therefore, through the cooperation of the second sealing ring 5 and the first sealing ring 4, the connection between the internal threaded connecting sleeve 1 and the valve faucet is double sealed, and the sealing performance of the connection between the joint and the valve faucet is improved.

[0028] like Figure 1 , 2As shown, in this embodiment, an inner sealing ring 10 and an outer sealing ring 11 are provided at the connection between the externally threaded exhaust pipe 3 and the internally threaded connecting pipe 2. The inner sealing ring 10 is located at the upper end of the externally threaded exhaust pipe 3, and the outer sealing ring 11 is located at the lower end of the internally threaded connecting pipe 2.

[0029] Moreover, the externally threaded exhaust pipe 3 is threadedly connected to the internally threaded connecting pipe 2. Since an inner sealing ring 10 and an outer sealing ring 11 are provided at the connection between the externally threaded exhaust pipe 3 and the internally threaded connecting pipe 2, it is beneficial to perform double sealing on the connection between the externally threaded exhaust pipe 3 and the internally threaded connecting pipe 2, and the sealing after the externally threaded exhaust pipe 3 and the internally threaded connecting pipe 2 are connected is effectively guaranteed. Moreover, the externally threaded exhaust pipe 3 can be conveniently loosened and disassembled from the internally threaded connecting pipe 2. When the filter screen 9 is clogged and needs to be replaced, the externally threaded exhaust pipe 3 and the filter screen 9 can be conveniently disassembled and replaced. Therefore, only the externally threaded exhaust pipe 3 and the filter screen 9 need to be replaced, and there is no need to replace the entire joint, so the replacement cost is low.

[0030] like Figure 1 , 5 As shown, in this embodiment, the upper end of the internal threaded connecting tube 2 is rotatably connected to a ball shaft 8, a vent 16 is passed through the middle of the ball shaft 8, a guide tube 6 extending upward from the ball shaft 8 is fixed to the inner wall of the vent 16, an exhaust port 15 is opened at the lower end of the internal threaded connecting sleeve 1, the upper end of the outer periphery of the guide tube 6 is fixed to the inner wall of the exhaust port 15, a metal corrugated hose 7 is connected between the internal threaded connecting sleeve 1 and the internal threaded connecting tube 2, and the guide tube 6 and the ball shaft 8 are both located in the metal corrugated hose 7.

[0031] When the exhaust angle of the joint needs to be adjusted, the internal threaded connecting tube 2 is twisted to swing in various directions along the ball shaft 8, and the internal threaded connecting tube 2 will cause the metal corrugated hose 7 to deform. When the gas enters the internal threaded connecting tube 2 through the guide tube 6 and the vent 16, the connection between the ball shaft 8 and the internal threaded connecting tube 2 is blocked by the metal corrugated hose 7, which helps prevent the gas in the internal threaded connecting tube 2 from leaking out of the joint. Therefore, it is convenient to adjust the exhaust angle of the joint, and also conveniently adjust the exhaust angle of the valve faucet.

[0032] like Figure 1 , 3 As shown in Figure 4, in this embodiment, a plurality of groups of damping limit assemblies are provided on the periphery of the ball shaft 8, and the damping limit assemblies are composed of a spring pressure rod 13 and a damping ball 14. A plurality of contraction grooves 12 are opened at the upper end of the inner wall of the internal threaded connecting tube 2, and the spring pressure rods 13 are connected to the contraction grooves 12, and the damping balls 14 are connected to the ends of the spring pressure rods 13. The damping balls 14 are in contact with the outer surface of the ball shaft 8, and the damping balls 14 are made of rubber material.

[0033] When the internal threaded connecting pipe 2 swings in various directions along the ball shaft 8, the spring pressure rod 13 is set to be in a compressed state, so the elastic force of the spring pressure rod 13 can drive the damping ball 14 to press on the outer surface of the ball shaft 8. When the damping ball 14 contacts the ball shaft 8, a damping force is generated, and a plurality of damping balls 14 are provided. When the angle of the internal threaded connecting pipe 2 is adjusted, it is helpful to prevent the internal threaded connecting pipe 2 from twisting accidentally, effectively ensuring the stability of use of the internal threaded connecting pipe 2 after the angle is adjusted, making the exhaust angle flexible and changeable, and the damping ball 14 is made of rubber material, which is helpful to reduce the wear on the ball shaft 8.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] The above embodiments are preferred implementation schemes of the present invention. In addition, other implementation schemes are also included. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
