Description

Technical Field

[0001] The utility model belongs to the technical field of shower equipment and relates to a movable lifting seat for a handheld shower. Background Art

[0002] As a part of shower equipment, handheld showerheads are widely used in various places. When using a handheld showerhead, it can be plugged into a lifting seat, which is arranged on the outside of the shower body and can be locked in position after being lifted relative to the shower body, so as to adjust the height of the handheld showerhead to meet the needs of users of different heights.

[0003] For example, people have designed a dual-function showerhead slide and applied for a Chinese patent, with the application number: 201821153281.4; its announcement number: CN208757893U; the dual-function showerhead slide comprises a slide body, the middle of which is provided with a sleeve hole for the showerhead lifting rod to pass through, and sockets for placing a handheld showerhead or a spray gun are respectively arranged at both ends of the slide body; the slide body is provided with a locking mechanism, which is composed of a button, a pressure pad and a spring. A slot hole for accommodating a locking mechanism is provided on the slide seat body, and one side of the slot hole is communicated with the sleeve hole. An inclined guide surface and a spring fixing seat are provided in the slot hole. The button is movably arranged in the slot hole and moves vertically up and down along the inclined guide surface in the slot hole. The pressure pad is installed on the side of the button facing the sleeve hole. The pressure pad generates a lateral displacement while moving up and down with the button. The change of the lateral displacement is used to tighten or loosen the lifting rod. The spring is installed on the spring fixing seat, and the two ends of the spring act on the spring fixing seat and the button respectively.

[0004] When the dual-function shower slide needs to be raised or lowered, the button can be pressed to retract the pressure pad, thereby releasing the position lock between the slide body and the shower lift rod. After adjusting the position of the slide body up or down, the button is released, the pressure pad is reset, and is pressed tightly against one side of the shower lift rod to achieve positioning of the slide body.

[0005] However, the dual-function shower slide is locked in position by squeezing a pressure pad on one side of the shower lift rod. The one-sided squeezing method makes the positioning between the slide body and the shower lift rod unstable, and the slide body is easy to rotate or slide down relative to the shower lift rod, which brings inconvenience to users. Utility Model Content

[0006] The purpose of the utility model is to solve the above problems existing in the prior art and to propose a movable lifting seat for a handheld shower head, thereby solving the problem of poor positioning stability of the existing shower head sliding seat.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A hand-held shower movable lifting seat comprises a seat body, the seat body has a socket for inserting a hand-held shower and a cylindrical sliding sleeve for being sleeved on the outside of the shower lifting rod, and is characterized in that the hand-held shower movable lifting seat also includes a cylindrical adjusting sleeve and an annular clamping ring, one end of the adjusting sleeve is threadedly connected to the sliding sleeve, and the other end is located outside the sliding sleeve, the clamping ring has a notch and is located inside the adjusting sleeve and the sliding sleeve, the adjusting sleeve has a protruding shoulder 1 inside, and the sliding sleeve has a protruding shoulder 2 inside, when the adjusting sleeve and the sliding sleeve are screwed toward each other, the shoulder 1 and the shoulder 2 can apply force to the two ends of the clamping ring and cause the clamping ring to shrink.

[0009] When the hand-held showerhead movable lifting seat is used, the sliding sleeve, the adjustment sleeve and the clamping ring are all sleeved on the outside of the showerhead lifting rod. Here, the showerhead lifting rod is the main rod of the shower head, and the clamping ring is located on the inside of the sliding sleeve and the adjustment sleeve. When the hand-held showerhead movable lifting seat needs to be fixed, the adjustment sleeve is held on the outside of one end of the sliding sleeve and rotated circumferentially, so that the adjustment sleeve and the sliding sleeve are close to each other, and the convex shoulder 1 and the convex shoulder 2 on the two are also close to each other, and act on the two ends of the clamping ring respectively. Because there is a notch on the clamping ring, under the action of the conical surface, the force of the convex shoulder 1 and the convex shoulder 2 approaching each other is converted into a force driving the clamping ring to contract radially, so that the clamping ring circumferentially clamps the showerhead lifting rod, thereby fixing the hand-held showerhead movable lifting seat and the showerhead lifting rod. Conversely, the adjustment sleeve is rotated in the opposite direction, so that the convex shoulder 1 and the convex shoulder 2 are separated from each other, and the force applied to the clamping ring is cancelled, then the clamping ring is loosened, and the seat body can be raised and lowered relative to the showerhead lifting rod to adjust the height position. In the movable lifting seat of the hand-held shower, the shower lifting rod is clamped by relying on the radial contraction of the annular clamping ring, so that multi-angle clamping in the circumferential direction is achieved, the fixation is more firm, and the stability is better.

[0010] In the above-mentioned hand-held showerhead movable lifting seat, an annular sealing ring 1 is fixed in the adjustment sleeve, the sealing ring 1 is located on the other side of the convex shoulder 1 relative to the clamping ring, and the inner side of the sealing ring 1 is used to abut against the outer wall of the showerhead lifting rod, and an annular sealing ring 2 is fixed in the sliding sleeve, the sealing ring 2 is located on the other side of the convex shoulder 2 relative to the clamping ring, and the inner side of the sealing ring 2 is used to abut against the outer wall of the showerhead lifting rod. Seal rings 1 and 2 are additionally arranged on both sides of the clamping ring, which can not only prevent scratches, but also reduce gaps and increase friction, further ensuring the stability of fixation.

[0011] In the above-mentioned hand-held showerhead movable lifting seat, the outer side of the adjustment sleeve located at one end outside the sliding sleeve has a plurality of protruding long strip-shaped operating parts, the length direction of the plurality of the operating parts is consistent with the axial direction of the sliding sleeve, and the plurality of the operating parts are distributed around the axis of the sliding sleeve. The design of the protruding operating part facilitates the user's operation and avoids slipping.

[0012] In the above-mentioned hand-held showerhead movable lifting seat, the notch is in the shape of an elongated strip and its length direction is consistent with the axial direction of the clamping ring, and the two ends of the notch extend to the end faces of the two ends of the clamping ring respectively. The width of the elongated notch in the circumferential direction is small, so that when the clamping ring is contracted, the contact surface with the showerhead lifting rod is larger, and the fixation is more stable.

[0013] In the above-mentioned movable lifting seat for hand-held shower, a cylindrical protective sleeve is fixed in the socket, which can avoid scratches and provide auxiliary positioning for the hand-held shower.

[0014] In the above-mentioned hand-held showerhead movable lifting seat, both ends of the clamping ring have tapered surfaces on the outside, and the convex shoulder 1 and the convex shoulder 2 can respectively abut against the two tapered surfaces. The axial force of the convex shoulder 1 and the convex shoulder 2 moving toward each other is decomposed into a part of the radial force by the tapered surface to drive the clamping ring to contract and deform radially, thereby clamping the showerhead lifting rod.

[0015] In the above-mentioned movable lifting seat for hand-held shower, the corresponding parts of the conical surface of the clamping ring on the first and second convex shoulders are provided with conical surfaces which can abut against the corresponding conical surfaces. The abutment of the conical surfaces makes the relative positions of the first convex shoulder, the second convex shoulder and the clamping ring more stable, and the contraction of the clamping ring is more uniform when the first convex shoulder and the second convex shoulder act against each other.

[0016] Compared with the prior art, the hand-held showerhead movable lifting seat relies on the radial contraction of the annular clamping ring to clamp the showerhead lifting rod, thereby achieving multi-angle clamping in the circumferential direction, more firm fixation and better stability.

DETAILED DESCRIPTION

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] like Figure 1As shown, the hand-held shower movable lifting seat comprises a seat body 1, which has a socket 11 for inserting a hand-held shower head 2 and a cylindrical sliding sleeve 12 for sleeved outside the shower lifting rod 3, the socket 11 and the sliding sleeve 12 are both arranged in the vertical direction and are located at both ends of the seat body 1. A cylindrical protective sleeve 8 is fixed in the socket 11.

[0022] The hand-held showerhead movable lifting seat also includes a cylindrical adjustment sleeve 4 and an annular clamping ring 5. The upper end of the adjustment sleeve 4 is inserted into the lower end of the sliding sleeve 12 and is threadedly connected to the sliding sleeve 12. The lower end of the adjustment sleeve 4 extends from the lower end of the sliding sleeve 12. In this embodiment, the ratio of the axial length of the portion of the adjustment sleeve 4 located inside the sliding sleeve 12 to the axial length of the portion of the adjustment sleeve 4 located outside the sliding sleeve 12 is less than 1 / 2, preferably 1 / 3; the outer side of the lower end of the adjustment sleeve 4 has a plurality of protruding long strip-shaped operating parts 42, the length direction of the plurality of operating parts 42 is consistent with the axial direction of the sliding sleeve 12, and the plurality of operating parts 42 are distributed around the axis of the sliding sleeve 12. Here, the operating parts 42 are tooth-shaped.

[0023] The clamping ring 5 has a notch 51 and is located inside the adjusting sleeve 4 and the sliding sleeve 12. Figure 2 As shown, the notch 51 of the clamping ring 5 is in the shape of an elongated strip and its length direction is consistent with the axial direction of the clamping ring 5. Both ends of the notch 51 extend to the end faces of the two ends of the clamping ring 5. Both ends of the clamping ring 5 have tapered surfaces 52 on the outside, and the diameter reduction directions of the two tapered surfaces 52 are opposite. Specifically, the diameter of the tapered surface 52 at the upper end of the clamping ring 5 gradually decreases from bottom to top, while the diameter of the tapered surface 52 at the lower end of the clamping ring 5 gradually decreases from top to bottom.

[0024] The inner wall of the adjusting sleeve 4 is located at the lower side of the clamping ring 5 and has a protruding annular shoulder 1 41, and the shoulder 1 41 has a conical surface that can be abutted against the conical surface 52 at the lower end of the clamping ring 5 at a position corresponding to the conical surface 52 at the lower end of the clamping ring 5; the inner wall of the sliding sleeve 12 is located at the upper side of the clamping ring 5 and has a protruding annular shoulder 2 121, and the shoulder 2 121 has a conical surface that can be abutted against the conical surface 52 at a position corresponding to the conical surface 52 at the upper end of the clamping ring 5. Of course, the number of conical surfaces 52 and conical surfaces can be reduced according to actual production needs.

[0025] The inner wall of the lower end of the adjustment sleeve 4 has a concave annular sealing groove 1, in which an annular sealing ring 6 is fixed, and the inner side of the sealing ring 6 extends out of the sealing groove 1 and abuts against the outer wall of the shower lifting rod 3, and the boss 41 is located between the sealing ring 6 and the clamping ring 5.

[0026] Similarly, the inner wall of the upper end of the sliding sleeve 12 has a sealing groove 2 which is concave in a circular shape. A sealing ring 2 7 in a circular shape is fixed in the sealing groove 2. The inner side of the sealing ring 2 7 extends out of the sealing groove 2 and abuts against the outer wall of the shower lifting rod 3. The boss 2 121 is located between the sealing ring 2 7 and the clamping ring 5.

[0027] When the handheld showerhead movable lifting seat is used, the sliding sleeve 12 , the adjusting sleeve 4 and the clamping ring 5 are all sleeved on the outside of the showerhead lifting rod 3 , and the clamping ring 5 is located inside the sliding sleeve 12 and the adjusting sleeve 4 and between the first convex shoulder 41 and the second convex shoulder 121 .

[0028] When the hand-held showerhead movable lifting seat needs to be fixed, the operating part 42 on the outer side of the lower end of the adjustment sleeve 4 is held and rotated circumferentially, so that the adjustment sleeve 4 and the sliding sleeve 12 are screwed in along the thread, and the convex shoulder 1 41 and the convex shoulder 2 121 on the inner sides of the two are close to each other and act on the conical surfaces 52 at both ends of the clamping ring 5. Because the clamping ring 5 has a notch 51, under the guidance of the conical surface 52, the force of the convex shoulder 1 41 and the convex shoulder 2 121 approaching each other is converted into a force driving the clamping ring 5 to contract radially, so that the clamping ring 5 clamps the showerhead lifting rod 3 in the circumferential direction, and the hand-held showerhead movable lifting seat and the showerhead lifting rod 3 are fixed.

[0029] On the contrary, the adjusting sleeve 4 is rotated in the opposite direction, so that the convex shoulder 1 41 and the convex shoulder 2 121 are separated from each other, and the force applied to the clamping ring 5 is cancelled, and the clamping ring 5 is loosened. Here, to ensure the loosening of the clamping ring 5, the clamping ring 5 can be made of rubber or plastic material with a certain elastic restoring force. After the clamping ring 5 is loosened, the seat body 1 can be raised or lowered relative to the shower lifting rod 3 to adjust the height position.

[0030] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
