Description

Technical Field

[0001] The utility model belongs to the technical field of bathroom accessories, and in particular relates to a shower arm with adjustable angle. Background Art

[0002] A shower arm is a metal fitting or bracket that is mounted on the bathroom wall to support and secure the shower head. It allows the shower head to remain at the appropriate height and position for the user to use while showering.

[0003] Most traditional shower arms adopt an integral structure. In order to ensure that the shower is in an ideal water-discharging state, the water outlet end of the shower arm should be perpendicular to the ground after the shower arm is installed. The angle adjustment of the water outlet end of the traditional shower arm is controlled by the depth of the thread at the end of the shower arm. For example, when the water outlet end needs to be rotated to the left, the thread at the end of the shower arm needs to be rotated deeper. When the water outlet end needs to be rotated to the right, the thread at the end of the shower arm needs to be rotated shallower. In the process of rotating the thread at the end of the shower arm shallower, the shower arm as a whole is prone to tilt, which can easily cause the shower arm to leak. Therefore, the method of adjusting the water outlet end of the shower arm by the depth of the thread is defective. Utility Model Content

[0004] The purpose of the utility model is to address the above-mentioned technical problems and provide an angle-adjustable shower arm. The horizontal direction of the water outlet end of the shower arm can be easily adjusted after installation, and the water outlet end is always perpendicular to the ground during the adjustment process. The connection of the water inlet end of the shower arm will not loosen, and the sealing effect is good.

[0005] In view of this, the present invention provides an angle-adjustable shower arm, comprising:

[0006] A main rod, one end of the main rod having a water inlet end, and the other end of the main rod having a water outlet end perpendicular to the water inlet end;

[0007] A connector, one end of which is connected to the water inlet pipe, and the other end of which is for the water inlet end of the main rod to extend into, and a mounting groove is provided on the side wall of the connector near one end of the main rod;

[0008] A clamping piece, one end of which is connected to the bottom surface of the mounting groove, and the other end of which can swing in the mounting groove;

[0009] An extrusion block is located outside the clamping piece, and a side wall of the extrusion block close to the clamping piece is inclined, and the inclined side of the extrusion block contacts the outer wall of the clamping piece;

[0010] The displacement mechanism is used to drive the extrusion block to move, so that the contact point between the extrusion block and the clamping piece moves on the inclined surface of the extrusion block, thereby realizing the clamping piece clamping and loosening the main rod.

[0011] After the water outlet end is rotated to the appropriate position, the extrusion block is driven by the displacement mechanism to make the high point of the upper inclined surface of the extrusion block contact with the clamping piece. In this process, the clamping piece clamps the water inlet end of the main rod to complete the adjustment of the horizontal angle of the water outlet end.

[0012] In the above technical solution, further, two mounting grooves are provided, and the two mounting grooves are symmetrically provided on both sides of the connecting head near one end of the main rod. Clamping plates are provided in the two mounting grooves, and each clamping plate corresponds to an extrusion block. The displacement mechanism can drive the two extrusion blocks to move at the same time.

[0013] In the above technical solution, further, the displacement mechanism includes an adjusting sleeve, an inner wall of the adjusting sleeve is provided with an internal thread, an outer wall of the main rod located at the water inlet end is provided with an external thread, the adjusting sleeve is threadedly connected to the main rod, the adjusting sleeve is connected to the extrusion block, and the extrusion block can move circumferentially along the adjusting sleeve.

[0014] In the above technical solution, further, a plurality of anti-slip strips are provided on the outer wall of the adjustment sleeve along the circumferential direction.

[0015] In the above technical solution, further, a positioning ring groove is provided on the inner wall of the connector near one end of the main rod, and the water inlet end of the main rod can abut against the positioning ring groove.

[0016] In the above technical solution, further, a sealing ring is provided between the water inlet end of the main rod and the positioning ring groove.

[0017] In the above technical solution, further, a plurality of rubber particles are provided on the side wall of the clamping piece close to the main rod.

[0018] The beneficial effects of the utility model are:

[0019] 1. By designing the shower arm to be a combination of a main rod, a connector, a clamping piece, an extrusion block, and a displacement mechanism, the horizontal direction of the water outlet can be adjusted after the shower arm is installed. During the adjustment process, the water outlet is always perpendicular to the ground, and the water flow effect is good. Moreover, when used after adjustment, the combination of the extrusion block and the clamping piece can tightly fix the main rod and the connector to prevent the main rod from loosening, and the sealing effect is good.

[0020] 2. By opening two mounting grooves symmetrically on both sides of the end of the connector, and arranging clamping pieces and extrusion blocks in both mounting grooves, after the main rod is clamped, the resultant clamping force is toward the center of the main rod. In this way, the shower arm is not prone to tilting between the main rod and the connector during use, further improving the sealing effect of the shower arm during use.

[0021] 3. By designing the displacement mechanism into an adjusting sleeve and threading the adjusting sleeve to the outer wall of the main rod through threaded matching, the displacement of the extrusion block is achieved. The threaded connection itself has a certain self-locking property, which can improve the stability of the extrusion block pushing against the clamping piece, thereby improving the connection stability between the main rod and the connecting head.

It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0035] Example 1

[0036] like Figures 1-8 As shown, this embodiment provides an angle-adjustable shower arm, comprising: a main rod 1, a connector 2, a clamping piece 3, an extrusion block 4, a displacement mechanism,

[0037] See also Figure 1 The lower end of the main rod 1 has a water inlet end 101, which is arranged along the axial direction of the main rod 1. The upper end of the main rod 1 has a water outlet end 102 perpendicular to the water inlet end 101. The outer wall of the water outlet end 102 is provided with a thread for connecting with the shower head. Figure 4 The main rod 1 has a flow channel inside that connects the water inlet end 101 and the water outlet end 102;

[0038] See also Figure 6 One end of the connector 2 is connected to the water inlet pipe, and the other end of the connector 2 is for the water inlet end 101 of the main rod 1 to extend into. A mounting groove 201 is provided on the side wall of the connector 2 near one end of the main rod 1, and the mounting groove 201 passes through the inner and outer walls of the connecting sleeve;

[0039] See also Figure 7 The lower end of the clamping piece 3 is connected to the bottom surface of the mounting groove 201, and the upper end of the clamping piece 3 extends along the axial direction of the connector 2 and can swing at a small angle in the mounting groove 201;

[0040] See also Figure 5 , the extrusion block 4 is located outside the clamping piece 3, the side wall of the extrusion block 4 close to the clamping piece 3 is inclined, and the inclined side of the extrusion block 4 contacts the outer wall of the clamping piece 3;

[0041] The displacement mechanism is used to drive the extrusion block 4 to move. The movement direction of the extrusion block 4 is the same as the axial direction of the connector 2, so that the contact point between the extrusion block 4 and the clamping piece 3 moves on the inclined surface of the extrusion block 4, thereby achieving the clamping and loosening of the main rod 1 by the clamping piece 3;

[0042] In this embodiment, there are two mounting grooves 201, which are symmetrically arranged on both sides of the connector 2 near the end of the main rod 1. A clamping piece 3 is provided in each mounting groove 201, and each clamping piece 3 corresponds to an extrusion block 4. The displacement mechanism can simultaneously drive the two extrusion blocks 4 to move.

[0043] In this embodiment, the high point of the inclined surface on the extrusion block 4 is defined as the high point, and the low point of the inclined surface is defined as the low point. When the contact point between the extrusion block 4 and the clamping plate 3 moves from the high point to the low point, a gap appears between the free end of the clamping plate 3 and the extrusion block 4. At this time, applying force to the main rod 1 can rotate the main rod 1 or pull the free end of the main rod 1 out of the connecting head 2. When the contact point between the extrusion block 4 and the clamping plate 3 moves from the low point to the high point, the free end of the clamping plate 3 pushes the extrusion block 4 toward the main rod 1, so that the inner side wall of the extrusion plate clamps the outer wall of the main rod 1.

[0044] When assembling the shower arm, insert the water inlet end 101 of the main rod 1 into the end of the connector 2 near the mounting groove 201. Then, the displacement mechanism drives the extrusion block 4 to move, so that the extrusion block 4 pushes the free end of the clamping piece 3 toward the main rod 1, so that the inner side wall of the clamping piece 3 clamps the water inlet end 101 of the main rod 1. The shower arm is assembled. At this time, connect the end of the connector 2 away from the main rod 1 to the water inlet pipe, and connect the water outlet end 102 of the main rod 1 to the shower head, and it can be used normally.

[0045] When the horizontal direction of the water outlet end 102 needs to be adjusted, the extrusion block 4 is first driven by the displacement mechanism so that the low point of the upper inclined surface of the extrusion block 4 contacts the clamping piece 3. At this time, the water inlet end 101 of the main rod 1 is loosened, and the main rod 1 can be rotated to adjust the horizontal direction of the water outlet end 102. After the water outlet end 102 is rotated to a suitable position, the extrusion block 4 is driven by the displacement mechanism so that the high point of the upper inclined surface of the extrusion block 4 contacts the clamping piece 3. In this process, the clamping piece 3 clamps the water inlet end 101 of the main rod 1 to complete the adjustment of the horizontal angle of the water outlet end 102.

[0046] It should be noted that, in this embodiment, for the disassembly and assembly process of the shower arm and the process of rotating the main rod 1 to adjust the horizontal angle of the water outlet end 102, the distance between the free end of the clamping plate 3 and the main rod 1 can be different. The control of this distance can be achieved by the distance that the extrusion block 4 moves relative to the clamping plate 3.

[0047] Example 2

[0048] This embodiment provides an angle-adjustable shower arm. In addition to the technical solutions of the above embodiments, it also discloses a structure of a displacement mechanism.

[0049] In this embodiment, please refer to Figure 1 The displacement mechanism includes an adjusting sleeve 5, an inner wall of the adjusting sleeve 5 is provided with an internal thread, and an outer wall of the main rod 1 located at the water inlet end 101 is provided with an external thread. The adjusting sleeve 5 is threadedly connected to the main rod 1, and the adjusting sleeve 5 is connected to the extrusion block 4. The extrusion block 4 can move along the circumferential direction of the adjusting sleeve 5;

[0050] In this embodiment, the adjusting sleeve 5 is first threaded onto the end of the main rod 1 close to the water inlet end 101, and then the water inlet end 101 of the main rod 1 is extended into the connecting head 2, and the extrusion block 4 is allowed to enter the mounting groove 201. At this time, the mounting groove 201 can limit the circumferential movement of the extrusion block 4 along the adjusting sleeve 5. In this way, when the adjusting sleeve 5 rotates and moves axially relative to the main rod 1, the extrusion block 4 will only move axially along the connecting head 2, thereby squeezing and releasing the clamping piece 3, thereby clamping and releasing the main rod 1.

[0051] Example 3

[0052] This embodiment provides an angle-adjustable shower arm. In addition to the technical solutions of the above embodiments, the structure of the adjustment sleeve 5 is optimized.

[0053] In this embodiment, please refer to Figure 8 A plurality of anti-slip strips 6 are provided on the outer wall of the adjustment sleeve 5 along the circumferential direction, which can improve the anti-slip effect when the user applies a rotational force to the adjustment sleeve 5 and reduce the difficulty of rotating the adjustment sleeve 5.

[0054] Example 4

[0055] This embodiment provides an angle-adjustable shower arm. In addition to the technical solutions of the above embodiments, the structure of the connector 2 is optimized.

[0056] In this embodiment, please refer to Figure 6 A positioning ring groove 7 is provided on the inner wall of the connector 2 near the end of the main rod 1. The water inlet end 101 of the main rod 1 can abut against the positioning ring groove 7. In this way, the positions of the main rod 1 and the connector 2 can be positioned during the assembly of the shower arm, reducing the difficulty of assembling the shower arm.

[0057] Also, see Figure 5 A sealing ring 8 is provided between the water inlet end 101 of the main rod 1 and the positioning ring groove 7, which can prevent water from leaking out from between the connecting head 2 and the water inlet end 101 of the main rod 1 during use, thereby improving the sealing performance of the shower arm.

[0058] Example 5

[0059] This embodiment provides an angle-adjustable shower arm. In addition to the technical solutions of the above embodiments, the structure of the clamping piece 3 is optimized.

[0060] In this embodiment, please refer to Figure 6 A number of rubber particles 9 are provided on the side wall of the clamping piece 3 close to the main rod 1; the rubber particles 9 have a certain elasticity, so when the clamping piece 3 contacts the outer wall of the main rod 1, the friction between the clamping piece 3 and the outer wall of the main rod 1 can be increased, thereby improving the clamping effect of the clamping piece 3 on the connecting end of the main rod 1.

[0061] The embodiments of the present invention are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
