Description

Technical Field

[0001] The utility model relates to the technical field of sanitary ware devices, in particular to a locking mechanism for a shower arm. Background Art

[0002] A shower arm, also known as a shower rod or a shower bracket, is a part of a sanitary ware device. The shower arm itself is a water-passing component and can fix and adjust the position of a shower head (such as an overhead shower).

[0003] In the prior art, the two rods of the shower arm are mainly locked by a screw and a nut at the end positions. However, the threaded connection structure usually has the risk of thread slipping, and the two rods cannot be effectively locked after the product has been used for a long time. Moreover, when the user operates, a relatively large force is required to loosen or tighten, and the operation is rather laborious.

[0004] In addition, using a locking mechanism similar to a screw and a nut causes the two rods of the shower arm to be necessarily non-collinear, and they are respectively in two parallel planes, with unstable force. The screw, as the rotating shaft of the two rods, will also necessarily penetrate into the water path of the shower arm, which will not only reduce the flow rate of the shower arm and make it difficult to meet the user's needs, but also put forward higher requirements for the quality of the screw: if the screw is a plastic part, it may be difficult to meet the strength requirements of the product, and the service life of the shower arm will be shortened; if the screw is a metal part, it must be guaranteed to be rust-proof, otherwise it will affect the water quality in the shower arm and further affect the user experience. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a locking mechanism for a shower arm to solve the problems existing in the prior art, and enable the user to operate more labor-savingly.

[0006] To achieve the above object, the solution of the utility model is:

[0007] A locking mechanism for a shower arm includes a housing, a bushing, a locking member, and a limiting member; the two sides of the housing are respectively provided with a first rod and an opening; a rotating shaft is arranged inside the housing; the bushing is movably and sealingly sleeved on the circumferential surface of the rotating shaft, and two sides of the bushing are respectively provided with a second rod communicating with the first rod and a first concave-convex part; the second rod penetrates out of the opening of the housing; the locking member is slidably and radially fitted in the housing along the bushing and is provided with a second concave-convex part matching the first concave-convex part; the limiting member is movably fitted on the sliding path of the locking member under the operation of the user, so that the second concave-convex part meshes with the first concave-convex part to lock the bushing.

[0008] The first concave-convex part is a plurality of straight teeth with first inclined surfaces on both sides, and the second concave-convex part is a plurality of straight teeth with second inclined surfaces on both sides.

[0009] The locking mechanism of the shower arm further comprises an elastic member acting on the locking member, for providing elastic force to make the second concave-convex portion engage with the first concave-convex portion; one end of the locking member is provided with an axis groove for embedding the elastic member.

[0010] Preferably, the limiting member is provided with a giving opening for giving way to the elastic member, and giving steps are provided on both sides of the giving opening; when the limiting member is in the sliding path of the locking member, the giving step is misaligned with the locking member, and the locking member can slide; when the limiting member is out of the sliding path of the locking member, the giving step is opposite to the locking member, and the locking member can slide to embed into the giving step and compress the elastic member at the same time.

[0011] The locking mechanism of the shower arm also includes an operating member installed on the surface of the shell for user operation; the operating member is a button with two ends swingingly engaged on the shell, and one end of which is movably connected to the limiting member; the limiting member is provided with a hook that is hooked on the inner wall of the operating member.

[0012] Preferably, a latch for swinging engagement with the operating member is provided in the housing.

[0013] Preferably, the locking mechanism of the shower arm further comprises a latch seat installed in the housing, and the latch seat is provided with a claw for embedding the latch.

[0014] The rotating shaft is a hollow structure and is connected to the first rod. An annular water groove is arranged on its circumference. A plurality of water holes connected to the rotating shaft are arranged at the bottom of the water groove. The second rod is connected to the water groove.

[0015] Preferably, a rotating shaft seat, an adapter and a bottom cover are arranged in the shell; the rotating shaft and a connecting shaft parallel to the rotating shaft are arranged on the surface of the rotating shaft seat facing the interior of the shell, and a connecting groove is arranged on the surface of the rotating shaft seat facing away from the interior of the shell, and the two ends of the connecting groove are respectively connected with the rotating shaft and the connecting shaft; the adapter is statically and sealingly inserted into the end of the first rod, and the connecting shaft is statically and sealingly inserted into the side of the adapter; the bottom cover is statically and sealingly covered on the periphery of the connecting groove.

[0016] Preferably, a partition is provided inside the housing. A nut is embedded at the end of the rotating shaft. A screw passes through the partition and is threadedly connected to the nut to lock the rotating shaft on the partition. A slider and a slider slot are provided between the adapter and the partition. The slider slot has a flared opening for the slider to pass through and a constricted opening for preventing the slider from disengaging from the slider slot.

[0019] (2) When the limiting member is on the sliding path of the locking member, it abuts against the end of the locking member. When the shaft sleeve rotates, it cannot push the locking member to compress the elastic member through the first concave-convex part and the second concave-convex part, so the shaft sleeve cannot rotate. When the user drives the limiting member through the operating member, the limiting member disengages from the sliding path of the locking member and no longer blocks the end of the locking member. When the shaft sleeve rotates, it can push the locking member to compress the elastic member through the first concave-convex part and the second concave-convex part, so the shaft sleeve can rotate freely to adjust the relative angle between the second rod and the first rod.

[0020] (3) Due to the elastic force of the elastic member, the limiting member can maintain the state of locking the shaft sleeve. When the shaft sleeve rotates, it will be subject to resistance from the limiting member, and it will not shake or change the angle due to the gravity of the first rod or the second rod when the user does not apply force.

[0050] In order to further explain the technical solution of the present invention, the present invention will be elaborated in detail below through specific embodiments.

[0051] Reference Figures 1-5 As shown, the present invention discloses a locking mechanism for a shower arm, including a housing 1, a bushing 2, a locking member 30, an elastic member 40, a limiting member 50 and an operating member 60;

[0052] On both sides of the housing 1, a first rod 11 and an opening 12 are respectively provided; a rotating shaft 31 is arranged inside the housing 1, and an annular water trough 311 is arranged on the circumferential surface of the rotating shaft 31, and the water trough 311 communicates with the first rod 11;

[0053] The bushing 2 is movably and sealingly sleeved on the circumferential surface of the rotating shaft 31, and on both sides thereof, a second rod 21 communicating with the water trough 311 and a first concave-convex portion 22 are respectively provided; the second rod 21 passes through the opening 12 of the housing 1;

[0054] The locking member 30 is slidably fitted in the housing 1 along the radial direction of the bushing 2, and is provided with a second concave-convex portion 301 matching the first concave-convex portion 22;

[0055] The elastic member 40 is arranged inside the housing 1 and acts on the locking member 30 to enable the second concave-convex portion 301 to engage with the first concave-convex portion 22 to lock the bushing 2;

[0056] The limiting member 50 is movably fitted on the sliding path of the locking member 30 to prevent the locking member 30 from separating from the bushing 2;

[0057] The operating member 60 is exposed outside the housing 1 and is linked with the limiting member 50, and is used to drive the limiting member 50 to disengage from or enter the sliding path of the locking member 30.

[0058] Through the above solution, the utility model realizes the restriction or unlocking of the sliding of the locking member 30 by the linkage of the operating member 60 and the limiting member 50. The user only needs to apply force to the operating member 60 by pressing or other means, which is convenient and fast. Thus, when the limiting member 50 is on the sliding path of the locking member 30, it abuts against the end of the locking member 30. When the sleeve 2 rotates, it cannot push the locking member 30 to compress the elastic member 40 through the first concave-convex portion 22 and the second concave-convex portion 301, so the sleeve 2 cannot rotate. When the user drives the limiting member 50 through the operating member 60, the limiting member 50 disengages from the sliding path of the locking member 30 and no longer blocks the end of the locking member 30. When the sleeve 2 rotates, it can push the locking member 30 to compress the elastic member 40 through the first concave-convex portion 22 and the second concave-convex portion 301, so the sleeve 2 can rotate freely to adjust the relative angle between the second rod 21 and the first rod 11. At the same time, due to the elastic force of the elastic member 40, the limiting member 30 can maintain the state of locking the sleeve 2. When the sleeve 2 rotates, it will be subject to resistance from the limiting member 30 and will not shake or change the angle due to the gravity of the first rod 11 or the second rod 21 when the user does not apply force.

[0059] The following shows specific embodiments of the utility model.

[0060] The above first concave-convex portion 22 is a plurality of straight teeth with first inclined surfaces 221 on both sides, and the second concave-convex portion 301 is a plurality of straight teeth with second inclined surfaces 3011 on both sides. By designing the first inclined surface 221 and the second inclined surface 3011, the circumferential torsion when the sleeve 2 rotates can be more converted into the radial thrust for pushing the locking member 30 to slide, so as to push the locking member 30 more smoothly when the limiting member 50 does not block the locking member 30. It can be understood that the number of straight teeth of the above first concave-convex portion 22 is reasonably designed according to the rotation range of the sleeve 2 required by the product, and the number of straight teeth of the second concave-convex portion 301 is set to 3 to 5 to meet the requirements.

[0061] The above elastic member 40 is a spring; a shaft groove 302 for embedding the elastic member 40 is provided at one end of the locking member 30.

[0062] Further, the above limiting member 50 is provided with a relief opening 501 for the elastic member 40 to avoid moving the position and state of the elastic member 40 when the limiting member 50 moves, and relief steps 502 are provided on both sides of the relief opening 501; when the limiting member 50 is on the sliding path of the locking member 30, the relief step 502 is misaligned with the locking member 30, and the limiting surface 503 of the limiting member 50 faces the locking member 30, and the locking member 30 cannot slide; on the contrary, when the limiting member 50 disengages from the sliding path of the locking member 30, the limiting surface 503 is misaligned with the locking member 30, and the relief step 502 faces the locking member 30, and the locking member 30 can slide to be embedded in the relief step 502 and compress the elastic member 40 at the same time.

[0063] The operating member 60 is a button with two ends swingingly engaged on the housing 1, and one end of the operating member 60 is movably connected to the limiting member 50; the limiting member 50 is provided with a hook 504 hooked on the inner wall of the operating member 60. When the user presses the operating member 60 away from one end of the limiting member 50, the limiting member 50 at the other end can be driven to break away from the sliding path of the locking member 30 by the swing of the operating member 60, thereby unlocking the rotation of the shaft sleeve 2; when the user presses the operating member 60 close to one end of the limiting member 50, the limiting member 50 can be pressed back to the sliding path of the locking member 30 synchronously, thereby locking the shaft sleeve 2. Since the operating member 60 is press-driven and the shower arm usually extends in the up and down directions, the position of the limit member 50 can be maintained after the user presses it, and the limit member 50 will not reset automatically, so that the user only needs to press the operating member 60 once to arbitrarily adjust the relative angle between the second rod 21 and the first rod 11, and press the operating member 60 again after the adjustment is completed to drive the limit member 50 to reset. There is no need to press the operating member 60 for a long time, and the operation is more convenient and quick, which is especially suitable for shower arms with longer first rod 11 and second rod 21.

[0064] Furthermore, a latch 70 for the operating member 60 to swing with is disposed in the housing 1 .

[0065] Secondly, the utility model further comprises a latch seat 80 installed in the housing 1, and the latch seat 80 is provided with a claw 801 for the latch 70 to be embedded. The latch seat 80 can be fixed in the housing 1 by screw locking.

[0066] The rotating shaft 31 is a hollow structure, and the bottom of the water channel 311 is provided with a plurality of water holes 312 connected to the rotating shaft 31, so that the water channel 311 is connected to the first rod 11 through the rotating shaft 31. Thus, the first rod 11-rotating shaft 31-water holes 312-water channel 311-second rod 21 constitute a water path at the rotating shaft position of the shower arm, so that the first rod 11 is connected to the second rod 21, and the water path of the rotating shaft 31 is connected from the inside of the rotating shaft 31 to the water channel 311 on the circumference of the rotating shaft 31. When the sleeve 2 rotates to any angle on the circumference of the rotating shaft 31, the rotating shaft 31 can be connected to the second rod 21 through its water channel 311. There are no other parts or structures in the rotating shaft 31, and the water flow is not blocked. The flow rate of the shower arm depends on the number and diameter of the water channels 312, which is easy to design and not affected by other factors. Compared with the structure of the prior art, it can achieve a larger and more stable flow rate, and the water quality will not be affected.

[0067] Further, the above-mentioned rotating shaft 31 can be directly integrally formed in the housing 1 and communicate with the first rod 11 through the water channel in the housing 1. However, considering the risk that the water channel with multiple turns may cause difficulty in demolding and cost increase, the present utility model provides a rotating shaft seat 3, a connecting piece 4 and a bottom cover 5 in the housing 1; the surface of the rotating shaft seat 3 facing the inside of the housing 1 is provided with the above-mentioned rotating shaft 31 and a connecting shaft 32 parallel to the rotating shaft 31, and the surface of the rotating shaft seat 3 facing away from the inside of the housing 1 is provided with a communication groove 33, and both ends of the communication groove 33 communicate with the rotating shaft 31 and the connecting shaft 32 respectively; the connecting piece 4 is statically sealed and inserted at the end of the first rod 11, and the connecting shaft 32 is statically sealed and inserted at the side of the connecting piece 4; the bottom cover 5 is statically sealed and covers the periphery of the communication groove 33. Thus, the bottom cover 5 and the communication groove 33 enclose a closed water channel between the connecting shaft 32 and the rotating shaft 31, and the first rod 11 communicates with the rotating shaft 31 through the connecting piece 4, the connecting shaft 32 and the communication groove 33; during production, the rotating shaft seat 3, the connecting piece 4 and the bottom cover 5 can all be independently produced and demolded, and since the connecting shaft 32 and the rotating shaft 31 are parallel, they can be demolded in the same direction, realizing the reduction of demolding difficulty; in addition, since the connecting piece 4 is inserted into the first rod 11, the connecting shaft 32 is inserted into the connecting piece 4, the shaft sleeve 2 is sleeved on the rotating shaft 31 and the second rod 21 is limited by the opening 12 to prevent the shaft sleeve 2 from moving axially on the rotating shaft 31.

[0068] In some embodiments of the present utility model, a first sealing ring 6 is provided between the connecting shaft 32 and the connecting piece 4; a second sealing ring 7 is provided between the connecting piece 4 and the first rod 11, both of which are to improve the sealing performance and prevent water leakage.

[0069] In some embodiments of the present utility model, the bottom cover 5 and the rotating shaft seat 3 are assembled and connected into a whole by means of welding, glue bonding, etc. to ensure the sealing performance. The preferred method is ultrasonic welding. A step portion 331 for the bottom cover 5 to cooperate is provided on the periphery of the connecting groove 33, and a flange 332 for welding is provided on the step portion 331.

[0070] In some embodiments of the present utility model, in order to make the structure of the product more stable and prevent the rotation shaft seat 3 from shaking under water pressure, a partition 13 is provided inside the housing 1. A nut 8 is embedded at the end of the rotation shaft 31, and a screw 9 passes through the partition 13 and is threadedly connected to the nut 8 to lock the rotation shaft 31 on the partition 13, thereby fixing the rotation shaft seat 3. At the same time, a slider 43 and a slider slot 131 are provided between the adapter 4 and the partition 13 to realize the installation limit of the adapter 4. The slider slot 131 has a flared opening for the slider 43 to pass through and a constricted opening for preventing the slider 43 from disengaging from the slider slot 131. After the slider 43 is inserted into the slider slot 131 through the flared opening, it moves towards the constricted opening until the end of the adapter 4 is inserted into the first rod 11. A snap 44 and a snap groove 34 are provided between the adapter 4 and the rotation shaft seat 3 to strengthen the connection after connection.

[0071] In this embodiment, the above-mentioned pin seat 80 and the rotation shaft 31 are locked with the same screw 9, that is, the screw 9 passes through the pin seat 80 and the partition 13 in sequence and is threadedly connected to the nut 8 on the rotation shaft 31. Only one screw 9 is required to fix two components inside the housing 1, and the installation is simpler. A corresponding chute is also designed inside the housing 1 for the locking member 30 to cooperate with and guide the locking member 30. Specifically, a chute 41 for the locking member 30 to slide and cooperate is provided on the peripheral surface of the adapter 4. The chute 41 is parallel to the first rod 11, and a channel for the locking member 30 to slide and cooperate is formed between the chute 41 and the partition 13 to guide it. In addition, a guide groove 42 for the limiting member 50 to move and cooperate can be provided at the end of the chute 41 to guide the movement of the limiting member 50.

[0072] In some embodiments of the present utility model, the above-mentioned housing 1 is fitted with a decorative cover 10 for covering components such as the rotation shaft seat 3, the adapter 4, and the bottom cover 5 to achieve a clean appearance.

[0073] The above-mentioned rotation shaft 31 is provided with annular mounting grooves 313 on both axial sides of the water passing groove 311, and third sealing rings 20 are provided in both mounting grooves 313. The third sealing rings 20 are tightly fitted between the peripheral surface of the rotation shaft 31 and the inner wall of the shaft sleeve 2 to achieve the effect of dynamic sealing.

[0074] The installation steps of some structures of the present utility model are as follows: After the locking member 30 and the elastic member 40 are installed in the adapter 4, the whole is installed in the housing 1, and the whole is relatively fixed to the housing 1 through the sliding engagement of the slider 43 and the slider slot 131. Then, the shaft sleeve 2 is installed at the opening 12, and then the rotation shaft seat 3 is installed in the housing 1 to assemble it with the adapter 4 and the shaft sleeve 2, and the rotation shaft seat 3 is locked with screws. After that, the limiting member 50 is passed through the partition 13 to cooperate with the locking member 30. Finally, the decorative cover 10 is ultrasonically welded to the housing 1.

[0075] The main improvement of the present utility model lies in the rotating shaft structure between the first rod 11 and the second rod 21. In actual products, this rotating shaft structure can have various applications:

[0076] Referring to Figure 6 , the first rods 11, 11' of the two shells 1, 1' can be connected into one rod, thereby forming a support arm with shells 1 at both ends; Referring to Figure 7 , the first rod 11 of the shell 1 and the sleeve 2 and the second rod 21 can be connected into one rod, thereby forming a support arm with a shell 1 and a sleeve 2 at both ends respectively; Referring to Figure 8 , the second rod 21 of the sleeve 2 can be integrally connected with the joint 90 with an external thread for connecting a shower head, or the second rod 21 of the shaft head 2 can be integrally connected with a joint with an internal thread for connecting a water supply end. With the above parts and other parts of the rotating shaft structure disclosed in the present utility model, a two-stage or even more-stage shower support arm can be combined to meet the requirements of different scenarios and be more flexible in use.

[0077] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by those of ordinary skill in the relevant technical field shall be regarded as not departing from the patent scope of the present utility model.
