Description

Technical Field

[0001] The utility model belongs to the technical field of pull-out faucet accessories, and particularly relates to a gravity ball for a pull-out faucet. Background Art

[0002] The nozzle of a pull-out faucet is often connected to the water inlet pipe through a hose. The user can hold the nozzle and pull it outward to the predetermined area to change the water outlet position of the nozzle. To ensure that the hose can be retracted in time when the nozzle is put back, a gravity ball will be installed on the hose under the countertop. The hose will be pulled back by the gravity ball, thereby achieving automatic resetting of the nozzle.

[0003] For example, a pull-out kitchen faucet with a pull-out shower head and a magnetic suction function disclosed in a Chinese patent with publication number CN217177576U includes a pull-out shower head, a pull-out cap, a pull-out tube and a hose. A pull-out plastic sleeve is installed at the upper end of the pull-out tube, and a second magnet is installed in the pull-out plastic sleeve through a plastic buckle; the pull-out cap is cylindrical, and the front end is provided with an internal thread that docks with the pull-out shower head, and the rear end is provided with a first magnet through a plastic compression cap; the front end of the hose is provided with a clamping edge that is clamped at the front end of the pull-out cap, and a sealing gasket is provided on the clamping edge. After the rear end of the hose passes through the pull-out cap, the pull-out plastic sleeve, and the pull-out tube in sequence, a counterweight ball is fixed at its rear end. The counterweight ball includes a left hemisphere and a right hemisphere, and the left hemisphere and the right hemisphere are fixed to the hose by screws. The pull-out shower head needs to leave the pull-out tube when in use. After the pull-out shower head is used, it is automatically recovered under the gravity of the counterweight ball, and the pull-out shower head is clamped and aligned with the pull-out tube.

[0004] The above-mentioned faucet is a common pull-out faucet on the market. Its counterweight ball (also called gravity ball) includes a left hemisphere and a right hemisphere, which are fixed to the hose by screws. In other words, when installing this type of gravity ball, additional tools such as screwdrivers are required, which is time-consuming. Moreover, the gravity ball is installed under the countertop, and the actual installation space is relatively small. In addition, the screws need to be tightened to stably clamp the left and right hemispheres on the hose, which makes installation inconvenient. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the prior art and to propose a gravity ball for a pull-out faucet. The technical problem to be solved by the utility model is: how to improve the convenience of installation of the gravity ball.

[0006] The above technical objectives of the utility model can be achieved through the following technical solutions:

[0007] A gravity ball for a pull-out faucet comprises a left hemisphere and a right hemisphere, wherein two sides of the left hemisphere are respectively provided with a side buckle 1 and a groove 1, the outer wall of the side buckle 1 is flush with the outer wall of the left hemisphere, and a boss 1 is arranged in the groove 1; two sides of the right hemisphere are respectively provided with a side buckle 2 and a groove 2, the outer wall of the side buckle 2 is flush with the outer wall of the right hemisphere, and a boss 2 adapted to the side buckle 1 is arranged in the groove 2; the side buckle 1 is clamped with the boss 2, and after the side buckle 2 is clamped with the boss 1, the left hemisphere is connected to the right hemisphere.

[0008] Through the above technical solution, side buckle one is flush with the outer wall of the left hemisphere, and side buckle two is flush with the outer wall of the right hemisphere. After the two hemispheres are connected, the outer walls of the left and right hemispheres are flush, and it is not easy to hook external debris. The installation process of this gravity ball does not require additional installation tools, and the installation is convenient. Even if it is installed in a small space, it can be installed quickly.

[0009] In the above-mentioned gravity ball for pull-out faucet, the left hemisphere and the right hemisphere have the same structure, which is convenient to produce, can significantly save mold opening and production costs, and reduce production costs.

[0010] In the above-mentioned gravity ball for pull-out faucet, the inner side of the side buckle 1 is provided with a limiting groove 1, and the side buckle 1 is clamped with the boss 2 through the limiting groove 1; the inner side of the side buckle 2 is provided with a limiting groove 2, and the side buckle 2 is clamped with the boss 1 through the limiting groove 2. The side buckle 1 is clamped with the boss 2 through the limiting groove 1, and the side buckle 2 is clamped with the boss 1 through the limiting groove 2. After the left hemisphere and the right hemisphere are connected, the connection effect is more stable.

[0011] In the above-mentioned gravity ball for pull-out faucet, the side buckle 1 has elastic deformation performance, and the end of the side buckle 1 is provided with a guide surface 1; the side buckle 2 has elastic deformation performance, and the end of the side buckle 2 is provided with a guide surface 2. When the left hemisphere and the right hemisphere are buckled together, the guide surface 1 can guide the limit groove 1 to the boss 2, and the guide surface 2 can guide the limit groove 2 to the boss 1, which saves more effort in installation.

[0012] In the above-mentioned gravity ball for pull-out faucet, the outer wall of the left hemisphere is provided with a deformation groove 1 close to the side buckle 1, and the outer wall of the right hemisphere is provided with a deformation groove 2 close to the side buckle 2. When the side buckle 1 is connected to the boss 2 and the side buckle 2 is connected to the boss 1, the side buckle 1 can be deformed toward the outer shape through the deformation groove 1, and the side buckle 2 can be deformed toward the outer shape through the deformation groove 2, so as to avoid damage to the side buckle 1 and the side buckle 2.

[0013] In the above-mentioned gravity ball for pull-out faucet, the side wall of the groove 1 can limit the side buckle 2, and the side wall of the groove 2 can limit the side buckle 1. The groove wall of the groove 1 limits the side buckle 1, and the groove wall of the groove 2 limits the side buckle 2, which can prevent shaking or abnormal displacement between the left hemisphere and the right hemisphere.

[0014] In the above-mentioned gravity ball for pull-out faucet, the left hemisphere has a cavity 1, a counterweight 1 is arranged in the cavity 1, the opening of the cavity 1 is limited by baffle 1, and the end face of baffle 1 is flush with the side wall of the left hemisphere; the right hemisphere has a cavity 2, a counterweight 2 is arranged in the cavity 2, the opening of the cavity 2 is limited by baffle 2, and the end face of baffle 2 is flush with the side wall of the right hemisphere. The left hemisphere and the right hemisphere are connected to the hose, and the two hemispheres provide gravity through counterweight 1 and counterweight 2, so that the hose can work normally.

[0015] In the above-mentioned gravity ball for pull-out faucet, the left hemisphere has a through hole 1, and the middle of the baffle plate 1 has a paving groove 1 connected to the through hole 1; the right hemisphere has a through hole 2, and the middle of the baffle plate 2 has a paving groove 2 connected to the through hole 2, and the paving groove 1 and the paving groove 2 can cooperate to clamp the hose. After the left hemisphere and the right hemisphere are connected, the baffle plate 1 contacts the baffle plate 2, and the paving groove 1 and the paving groove 2 are used for the installation of the hose.

[0016] In the above-mentioned gravity ball for pull-out faucet, the side wall of the first clearance groove is provided with a plurality of first contacts, and the side wall of the second clearance groove is provided with a plurality of second contacts, and the second contacts and the first contacts are symmetrically arranged, and both are used to press against the hose. The first clearance groove presses against the outer wall of the hose through the first contact, and the second clearance groove presses against the outer wall of the hose through the second contact, which can further increase the friction force of the two hemispheres on the hose and prevent the gravity ball from sliding on the hose; in addition, the arrangement of the first contact and the second contact ensures that the first clearance groove and the second clearance groove will not over-squeeze the hose, thereby affecting the flow rate of the hose.

[0017] In the above-mentioned gravity ball for pull-out faucet, at least one set of positioning grooves 1 and positioning blocks 1 are arranged at intervals on the end surface of baffle 1, and at least one set of positioning grooves 2 and positioning blocks 2 are arranged at intervals on the end surface of baffle 2. After the left hemisphere is connected to the right hemisphere, the first positioning groove limits the second positioning block, and the second positioning groove limits the first positioning block. After the left hemisphere and the right hemisphere are connected, the first positioning block is inserted into the second positioning groove, and the second positioning block is inserted into the first positioning groove, which can further prevent the two hemispheres from shaking and improve the connection stability between the left hemisphere and the right hemisphere.

[0018] In summary, the beneficial effects of the present invention compared with the prior art are as follows:

[0019] The side buckle 1 is connected to the boss 2 through the limiting groove 1, and the side buckle 2 is connected to the boss 1 through the limiting groove 2, so that the left hemisphere and the right hemisphere are connected into a whole and clamped on the hose. The installation process of this gravity ball does not require additional installation tools, and the installation is convenient. Even if it is installed in a small space, it can be quickly installed. Moreover, the left hemisphere and the right hemisphere have the same structure. In actual production, only one of the hemispheres needs to be produced, which is convenient for production and can significantly save mold opening costs; in addition, the side buckle 1 is flush with the outer wall of the left hemisphere, and the side buckle 2 is flush with the outer wall of the right hemisphere. After the two hemispheres are connected, the outer walls of the left hemisphere and the right hemisphere are flush, which is not easy to hook external debris and will not affect the normal operation of the hose; at the same time, the groove wall of the groove 1 is limited to the side buckle 1, and the groove wall of the groove 2 is limited to the side buckle 2, so that there will be no displacement between the two hemispheres, and the connection effect is more stable.

[0040] like Figure 4-Figure 7 As shown, the left hemisphere 100 has a cavity 140, a counterweight 141 is disposed in the cavity 140, the opening of the cavity 140 is limited by a baffle 1 300 to the counterweight 141, and the end surface of the baffle 1 300 is flush with the side wall of the left hemisphere 100; the right hemisphere 200 has a cavity 240, a counterweight 241 is disposed in the cavity 240, the opening of the cavity 240 is limited by a baffle 2 400 to the counterweight 241, and the end surface of the baffle 2 400 is flush with the side wall of the right hemisphere 200. In some embodiments, the counterweight 141 and the counterweight 241 are iron sand or other high-density, high-weight media.

[0041] The baffle plate 1 300 and the left hemisphere 100 may be connected by snapping, bolting or integrally formed, and correspondingly, the baffle plate 2 400 and the right hemisphere 200 may also be connected by snapping, bolting or integrally formed.

[0042] like Figure 4-Figure 7 As shown, the left hemisphere 100 has a through hole 150 penetrating through it, and the middle of the baffle 1 300 has a clearance groove 310 connected to the through hole 150; the right hemisphere 200 has a through hole 250 penetrating through it, and the middle of the baffle 2 400 has a clearance groove 410 connected to the through hole 250. After the left hemisphere 100 and the right hemisphere 200 are connected, the through hole 150 is connected to the through hole 250, and the clearance groove 1 310 is connected to the clearance groove 2 410 and can cooperate to clamp the hose 1.

[0043] Furthermore, a plurality of contacts 1 311 are arranged at intervals on the side wall of the first clearance groove 310 , and a plurality of contacts 2 411 are arranged at intervals on the side wall of the second clearance groove 410 . The contacts 2 411 and the contacts 1 311 are arranged symmetrically, and both are used to press against the outer wall of the hose 1 .

After the guide surface 112 passes over the boss 221, The boss 221 enters the limiting groove 111, and the connection between the side buckle 110 and the boss 221 is completed; at the same time, the side buckle 210 will be inserted into the groove 120 through the guide surface 212, and the side buckle 210 will contact the boss 121 and stretch outward and deform. After the guide surface 212 passes over the boss 121, the boss 121 enters the limiting groove 211, and the connection between the side buckle 210 and the boss 121 is completed.

[0048] At this time, the second positioning block 430 is inserted into the first positioning groove 320 , the first positioning block 330 is inserted into the second positioning groove 420 , and the first contact 311 and the second contact 411 jointly press the outer wall of the hose 1 .

[0049] When the right hemisphere 200 and the left hemisphere 100 need to be disassembled, it is only necessary to remove the side buckle 210 from the groove 1 120 and the side buckle 110 from the groove 220 .

[0050] The specific embodiments described in this article are merely examples of the spirit of the utility model; technicians in the technical field to which the utility model belongs can make various modifications or additions to the described specific embodiments or replace them in a similar manner, but will not deviate from the spirit of the utility model or exceed the scope defined by the attached claims.
