Abstract
Description
Technical Field
[0001] This utility model relates to the field of buffer device technology, and in particular to a buffer device for a faucet handle. Background Technology
[0002] A faucet handle damper is a common protective device in faucets. When the faucet handle is closed, the damper contacts the countertop and absorbs the impact force through the elastic deformation of the rubber material, thereby extending the faucet's service life and improving operational stability.
[0003] When a faucet handle is turned on or off, the countertop will compress the rubber ring in the buffer device. Although the rubber ring has a relatively good deformation capacity, prolonged compression will reduce the deformation capacity of the rubber ring, which will lead to gaps between the buffer device and the countertop, thus reducing the buffering performance of the buffer device. Utility Model Content
[0004] This invention provides a faucet handle cushioning device to address the problem that prolonged compression can reduce the deformation capacity of the rubber ring, leading to gaps between the cushioning device and the tabletop, thus reducing the cushioning performance of the cushioning device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a buffer device for a faucet handle, comprising a plastic cylinder, a connecting ring fixedly installed on the outer surface of the plastic cylinder, and rubber rings provided on both sides of the connecting ring. Both rubber rings are fixedly installed on the outer surface of the plastic cylinder. The connecting ring and the rubber rings are hollow structures, and the inner walls of the connecting ring and the two rubber rings are connected. An adjustment device is provided inside the connecting ring. The adjustment device adjusts the expansion degree of the rubber rings by providing two circular rings on the inner wall of the connecting ring and respectively pushing gas into the interior of the two rubber rings.
[0006] The effect achieved by the above-mentioned components is as follows: by setting two rings, the rings are pushed to slide on the inner wall of the connecting ring. Since both air bladders are connected to the inner wall of the connecting ring, the gas will cause the rubber ring to expand. When the rubber ring and the faucet countertop are gapped due to long-term compression, the rubber ring can be inflated by inflating the inside of the rubber ring, causing the rubber ring to expand and then re-abut against the faucet countertop, thus filling the gap and preventing the buffering performance of the buffer device from deteriorating.
[0007] Preferably, the adjusting device includes two rings, both of which are slidably mounted on the inner wall of the connecting ring. A common rotating shaft is provided between the two rings, and support rods are symmetrically fixedly mounted on the outer surface of the rotating shaft. The rotating shaft is rotatably mounted on the inner wall of the connecting ring.
[0008] The effect achieved by the above components is as follows: when the shaft is rotated, the shaft will drive the two support rods to rotate. During the rotation of the two support rods, the angle between the support rods and the rings will gradually increase. One end of the support rod will push the two rings respectively, so that the two rings slide in opposite directions on the inner wall of the connecting ring. During the sliding process, the rings will push air into the interior of the rubber ring, causing the rubber ring to expand. Thus, the degree of deformation of the rubber ring can be adjusted according to actual needs.
[0009] Preferably, rubber rings are installed on both the inner and outer sides of the ring, and the outer surfaces of both rubber rings abut against the inner wall of the connecting ring.
[0010] The effect achieved by the above components is that by setting the rubber ring, the rubber ring can provide an auxiliary seal between the inner walls of the circular ring and the connecting ring, which helps to prevent the gas inside the rubber ring from escaping through the gap between the circular ring and the connecting ring.
[0011] Preferably, springs are symmetrically fixedly installed on the side of the two rings that are close to each other.
[0012] The effect achieved by the above components is as follows: by setting up a spring, when the spring is not subjected to other external forces, it will pull the two rings. When the two rings move away from each other, they will stretch the spring, causing the spring to deform. When the rotating shaft is rotated, the angle between the support rod and the ring gradually decreases, the tension on the spring decreases, it will reset, and drive the ring to move. Thus, the degree of shrinkage of the rubber ring can be adjusted by rotating the shaft, improving the controllability of the rubber ring adjustment.
[0013] Preferably, the spring has a round rod inside, and the two rings are slidably mounted on the outer surfaces of the two round rods. The two ends of the round rods are respectively fixedly mounted on the top and bottom of the inner wall of the connecting ring.
[0014] The effect achieved by the above-mentioned components is that by setting up the round rod, the round rod can limit and guide the spring, which helps to prevent the spring from bending easily.
[0015] Preferably, the connecting ring has symmetrical through holes in the middle of its outer surface, and the through hole groove is located on one side of the spring.
[0016] The effect achieved by the above-mentioned components is that by setting through holes, the inside and outside of the connecting ring are connected, which helps to prevent the problem of the connecting ring being difficult to adjust under air pressure due to the inside being closed.
[0017] Preferably, a fixing component is provided at one end of the rotating shaft. The fixing component includes an operating block, which is fixedly installed at one end of the rotating shaft. The outer surface of the connecting ring is symmetrically provided with auxiliary grooves. The operating block is disposed on the inner wall of the auxiliary groove, and bolts are symmetrically threaded into the inner wall of the operating block.
[0018] The effect achieved by the above components is as follows: by rotating the bolt, one end of the bolt abuts against one side of the inner wall of the auxiliary groove, the bolt can fix the operating block, thereby allowing the rotating shaft to rotate, which helps to prevent the rotating shaft and support rod from rotating and causing the ring to shift.
[0019] Preferably, a rubber pad is installed on one side of the inner wall of the auxiliary groove, and the rubber pad is sleeved on the outer surface of the rotating shaft.
[0020] The effect achieved by the above-mentioned components is that by setting a rubber pad to replace one side of the inner wall of the auxiliary groove in contact with one end of the bolt, the friction between the bolt and the auxiliary groove can be increased, making the bolt less likely to loosen.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, two rings are provided, which slide against the inner wall of the connecting ring. Since both air bladders are connected to the inner wall of the connecting ring, the gas causes the rubber ring to expand. When a gap forms between the rubber ring and the faucet countertop due to prolonged compression, the rubber ring can be inflated by filling it with air, causing it to expand and re-engage with the faucet countertop, thus filling the gap and preventing the buffering performance of the buffer device from deteriorating.

[0029] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a buffer device for a faucet handle, including a plastic cylinder 1. A connecting ring 2 is fixedly installed on the outer surface of the plastic cylinder 1. Rubber rings 3 are provided on both sides of the connecting ring 2. Both rubber rings 3 are fixedly installed on the outer surface of the plastic cylinder 1. The connecting ring 2 and the rubber rings 3 are hollow structures. The inner walls of the connecting ring 2 and the two rubber rings 3 are connected. An adjustment device 4 is provided inside the connecting ring 2. The adjustment device 4 provides two rings 41 on the inner wall of the connecting ring 2, and pushes gas into the interior of the two rubber rings 3 to adjust the expansion degree of the rubber rings 3. By providing two rings 41, the rings 41 are pushed to slide on the inner wall of the connecting ring 2. Since the two air bladders are connected to the inner wall of the connecting ring 2, the gas will cause the rubber rings 3 to expand. When the rubber rings 3 have gaps between them and the faucet countertop due to long-term compression, the rubber rings 3 can be inflated by inflating them, causing them to expand and re-engage with the faucet countertop, thus filling the gaps and preventing the buffer device from deteriorating.
[0030] Reference Figures 2-5 As shown, the adjusting device 4 includes two rings 41, both of which are slidably mounted on the inner wall of the connecting ring 2. A common rotating shaft 42 is provided between the two rings 41. Support rods 43 are symmetrically fixed to the outer surface of the rotating shaft 42. The rotating shaft 42 is rotatably mounted on the inner wall of the connecting ring 2. Rotating the rotating shaft 42 causes the two support rods 43 to rotate. During rotation, the angle between the support rods 43 and the rings 41 gradually increases, and one end of each support rod pushes the two rings 41, causing the two rings 41 to move within the inner wall of the connecting ring 2. The ring 41 slides in opposite directions, pushing air into the rubber ring 3 during the sliding process, causing the rubber ring 3 to expand. This allows for adjustment of the deformation of the rubber ring 3 as needed. Rubber rings 44 are installed on both the inner and outer sides of the ring 41. The outer surfaces of both rubber rings 44 abut against the inner wall of the connecting ring 2. By setting the rubber rings 44, they can provide auxiliary sealing between the inner walls of the ring 41 and the connecting ring 2, which helps prevent gas inside the rubber ring 3 from escaping through the gap between the ring 41 and the connecting ring 2.
[0031] Reference Figures 2-5As shown, springs 45 are symmetrically fixed on the side of the two rings 41 that are close to each other. By setting springs 45, when there is no other external force, springs 45 will pull the two rings 41. When the two rings 41 move away from each other, springs 45 will be stretched, causing springs 45 to deform. When the rotating shaft 42 is rotated, the angle between the support rod 43 and the rings 41 gradually decreases, the tension on springs 45 decreases, and they will reset and drive the rings 41 to move. Thus, the degree of shrinkage of the rubber ring 3 can also be adjusted by rotating shaft 42, improving the controllability of the rubber ring 3 adjustment. A round rod 46 is set inside the spring 45. The two rings 41 are slidably installed on the outer surface of the two round rods 46. The two ends of the round rods 46 are fixedly installed on the top and bottom of the inner wall of the connecting ring 2, respectively. By setting round rods 46, the round rods 46 can limit and guide the springs 45, which helps to prevent the springs 45 from bending easily.
[0032] Reference Figure 4 and Figure 5 As shown, through holes 47 are symmetrically opened in the middle of the outer surface of the connecting ring 2. The through hole 47 is located on one side of the spring 45. By setting the through hole 47, the inside and outside of the connecting ring 2 are connected, which helps to prevent the problem of the connecting ring 2 being closed and making it difficult to adjust the ring 41 under the action of air pressure.
[0033] Reference Figure 2 and Figure 3 As shown, a fixing component 5 is provided at one end of the rotating shaft 42. The fixing component 5 includes an operating block 52, which is fixedly installed at one end of the rotating shaft 42. An auxiliary groove 51 is symmetrically opened on the outer surface of the connecting ring 2. The operating block 52 is set on the inner wall of the auxiliary groove 51. Bolts 53 are symmetrically threaded into the inner wall of the operating block 52. By rotating the bolts 53, one end of the bolts 53 abuts against one side of the inner wall of the auxiliary groove 51, thus fixing the operating block 52 and allowing the rotating shaft 42 to rotate. This helps to prevent the rotating shaft 42 and the support rod 43 from rotating and causing the ring 41 to shift. A rubber pad 54 is installed on one side of the inner wall of the auxiliary groove 51. The rubber pad 54 is sleeved on the outer surface of the rotating shaft 42. By setting the rubber pad 54, instead of one side of the inner wall of the auxiliary groove 51 abutting against one end of the bolt 53, the friction between the bolt 53 and the auxiliary groove 51 can be increased, making the bolt 53 less likely to loosen.
[0034] Working principle: Rotating the operating block 52 drives the rotating shaft 42 to rotate, which in turn drives the two support rods 43 to rotate. During rotation, the angle between the support rods 43 and the rings 41 gradually increases, and one end of each support rod pushes the two rings 41, causing them to slide in opposite directions on the inner wall of the connecting ring 2. As the rings 41 slide, they stretch the spring 45, causing it to deform and push air into the rubber ring 3, causing it to expand. Simultaneously, rotating the operating block 52 in the opposite direction drives the rotating shaft and support rods 43 to rotate, thus increasing the angle between the support rods 43 and the rings 41. As the angle between rod 43 and ring 41 gradually decreases, the tension on spring 45 decreases, causing it to reset and move the two rings 41 toward each other. This draws out some of the gas in rubber ring 3, causing it to shrink. This allows the deformation of rubber ring 3 to be adjusted according to actual needs. After adjustment, bolt 53 is rotated so that one end of bolt 53 abuts against the rubber pad 54 on the inner wall of auxiliary groove 51. Bolt 53 can then fix operating block 52, thereby allowing the rotating shaft 42 to rotate. This helps prevent the rotating shaft 42 and support rod 43 from rotating and causing ring 41 to shift.
