Description

SLIDABLE SLEEVE STRUCTURE

The present invention relates to the technical field of sanitary and bathroom equipments, in particular to a slidable sleeve structure.

In a common shower, a slidable sleeve is usually used in a shower head riser rail to fix a handheld shower head; the slidable sleeve can move longitudinally on the shower head riser rail to achieve height adjustment and can also rotate about the shower head riser rail, thereby adjusting a height and an orientation of the handheld shower head.

A commonly available slidable sleeve in the market usually achieves positional adjustment by pressing a button. For example, according to an adjustable shower head holder disclosed in CN2887456Y (Chinese utility model application No. CN200520121239.0), a button on a slidable sleeve is pressed to slide in an inclined chute to drive a clamping block to release the clamping effect against a shower head riser rail, so that the slidable sleeve can move up and down; and when the button is released, the slidable sleeve is fixed on the shower head riser rail and stops sliding. However, the existing slidable sleeve requires a greater pressing force, and is therefore inconvenient to operate. In addition, the slidable sleeve is provided with a sleeve hole in the middle to allow the shower head riser rail to pass through. During installation, the shower head rising rail can only be locked on a wall body through fixing seats after the slidable sleeve sleeves onto the shower head rising rail through the sleeve hole from one end of the shower head rising rail. Therefore, if the slidable sleeve is damaged and needs to be replaced, the fixing seat at one end of the shower head riser rail needs to be removed from the wall body first before the slidable sleeve can be withdrawn from said one end of the shower head rising rail. Therefore, it is inconvenient to remove and replace the slidable sleeve.

Therefore, in order to make the adjustment easier, an easy-to-slide sliding seat for a shower head riser rail is disclosed in CN 214738486 U, comprising a seat body; a through hole which the shower head riser rail can pass through is arranged on the seat body; a clamping element capable of clamping the shower head riser rail is further arranged in the seat body; the clamping element is similar to a clip structure; and when a user rotates a switching sleeve either upwardly or downwardly, the clamping element can release its clamping effect against the shower head riser rail. Accordingly, the sliding seat is slidably adjustable on the shower head riser rail, and the convenience of operation is greater improved. However, although the force required from user to achieve adjustment of the sliding seat is reduced due to the idea of leverage in this utility model, the clamping element, which is arranged inside the seat body, still requires the seat body to sleeve onto the shower head riser rail from one end thereof before fixing the shower head riser rail on a wall. Therefore, it is still inconvenient to remove and replace the sliding seat. Furthermore, during position adjustment, the seat body needs to be controlled to slide on the shower head riser rail for a certain distance, and during sliding, the seat body may be blocked from moving up or down due to interference and blocking by other protrusions on the wall, thereby limiting the actual range of application of the product.

There is also a slidable sleeve available in the market featuring convenient assembly and disassembly. For example, a shower head sliding seat disclosed in CN 218204736 U comprises a mounting seat and a locking sleeve, one end of the mounting seat is mounted on the shower head riser rail; another end of the mounting seat opposite to the shower head riser rail is provided with the locking sleeve; and the locking sleeve needs to be rotated to be withdrawn so as to remove the sliding seat, and such operation is troublesome and time consuming.

opening 112. The movable member 2 and the pressing member 3 are positioned on two sides of the side opening 112 of the mounting opening 11; the movable member 2 and the pressing member 3 are movable between a close position and an open position, and the movable member 2 and the pressing member 3 are biased to the close position by the elastic member 4; in said close position, the side opening 112 of the mounting opening 11 is narrowed compared to the side opening 112 when the movable member 2 and the pressing member 3 are at the open position, and in said close position, the shower head riser rail in the through hole 111 is clamped and fixed.

Specifically, as shown in FIG. 3 to FIG. 5, the movable member 2 is reciprocally slidable in a sliding slot 12 of the fixed member 1. One end of the movable member 2 facing towards the through hole 111 is provided with a first abutting portion 21. The first abutting portion 21 is recessed to form an arc-shaped first abutting surface 211. The movable member 2 further extends towards the pressing member 3 to form a first linkage portion 22. A horizontally arranged rack structure 221 is arranged on the first linkage portion 22.

The opening end 151 of the inner fixed member 1 a is inserted into the outer fixed member lb from the sleeve connection hole 142 and is limited and enclosed by the sleeve connection portion 152. The sleeve connection hole 142 encloses the connecting end 141 of the inner fixed member 1 a. At least one positioning protrusion 1411 is arranged on the connecting end 141 abutting and being limited at an inner side of a positioning flange 1421 of the sleeve connection hole 142.

The connecting portion 14 is cylindrical. An outer side surface of the fixed pressing portion 15 is an arc surface. One side of the fixed pressing portion 15 facing towards the pressing member 3 is an inclined surface, so that a tail part of the fixed pressing portion 15 is tapered to form a first pressing space 51 on the fixed pressing portion 15 the pressing portion 33 can be pressed towards the fixed pressing portion 15. The outer side surface of the fixed pressing portion 15 is further provided with a fixed concave surface 153, which is convenient for handheld to facilitate pressing.

In this embodiment, two connecting lugs 16 extending out of the outer fixed member lb and spaced apart from each other are convexly arranged on one side of the fixed pressing portion 15 of the fixed member 1 proximal to the mounting opening 11. The rotating shaft 13 is a pin, and the pin penetrates through two connecting holes 161 on the two connecting lugs 16 respectively. The outer fixed member lb is convexly provided with two shielding portions 162 corresponding to the two connecting lugs 16. The two shielding portions 162 are located on outer sides of the two connecting lugs 16 respectively. When the outer fixed member lb sleeves the inner fixed member 1 a, the two connecting holes 161 are partially or completely shielded by the two shielding portions 162 to limit and fix the pin in the connecting holes 161 of the two connecting lugs 16.

In this embodiment, referring to FIG. 6, the pressing member 3 comprises an inner pressing member 3a and an outer pressing member 3b, and a pressing cavity 36 is formed in the outer pressing member 3b, and the inner pressing member 3a is sleeved by the pressing cavity 36.

One end of the inner pressing member 3a is provided with the second abutting portion 31. The second abutting surface 311 is arranged at a position of the second abutting portion 31 adjacent to the mounting opening 11. The rotating portion 32 is arranged at a bottom side of a middle part of the inner pressing member 3a. The rotating portion 32 protrudes out of the outer pressing member 3b. Another side of the inner pressing member 3a is provided with a pressing interior portion 331 accomodated inside the pressing cavity 36; the pressing interior portion 331 and an outer end 332 of the outer pressing member 3b together define the pressing portion 33 One side of the pressing portion 33 facing towards the fixed member 1 is also an inclined surface, so that a tail part of the pressing portion 33 is tapered to form a second pressing space 52; the first pressing space 51 and the second pressing space 52 together define the pressing space 5, thereby ensuring a larger pressing space 5, so that the pressing portion 33 can greatly compress the pressing space 5 to bring itself close to the fixed pressing portion 15 and thus fully open the side opening 112. Therefore, an outer side surface of the pressing portion 33 is also an arc surface; the arc surface of the outer side surface of the pressing portion and the arc surface of the outer side surface of the fixed pressing portion 15 are parts of a perimeter of a same circle, so as to reduce the overall size of the fixing seat 10 and reduce the product size. Furthermore, a pressing concave surface 333 is formed on the outer side surface of the pressing portion 33 in cooperation with the fixed concave surface 153 of the fixed pressing portion 15 of the fixed member 1 to facilitate two fingers of a user to hold and press.

The rotating portion 32 of the pressing member 3 sleeves the rotating shaft 13, which is the pin, and the rotating portion 32 is located between the two connecting lugs 16; a mounting cavity 321 is arranged in a middle of the rotating portion 32 of the pressing member 3, so that the torsion spring body 411 is accommodated in the mounting cavity 321 and sleeves the rotating shaft 13.

The rack structure 221 of the first linkage portion 22 is provided in the sliding slot 12 and below the pin. The gear structure 341 of the second linkage portion 34 is arranged on the rotating portion 32. Specifically, the gear structure 341 comprises a plurality of teeth circumferentially distributed on the rotating portion 32. In this embodiment, four teeth are provided, and correspondingly, the rack structure 221 can be provided with four teeth horizontally distributed and parallel to one another. The gear structure 341 can rotate about the pin, so that the teeth circumferentially distributed on the gear structure 341 and the teeth horizontally distributed on the rack structure 221 are engagable to perform movements according to rack and pinion mechanism.

In this embodiment, said one end of the torsion spring 41 is inserted and thus limited in the pressing cavity 36 of the outer pressing member 3b of the pressing member 3, and said another end of the torsion spring 41 is inserted and thus limited in the sleeve connection cavity 1521 of the outer fixed member lb of the fixed member 1. An accommodating slot 25 corresponding to the torsion spring 41 is provided on the first linkage portion 22 of the movable member 2 and extends down to the sliding portion 24 of the movable member 2, so as to prevent the torsion spring 41 from blocking the reciprocating sliding of the movable member 2. In this embodiment, the torsion spring 41 provides elastic supporting force, so that the pressing member 3 and the movable member 2 are always biased to the close position where the shower head riser rail in the mounting opening 11 is always being pressed against by the pressing member and being abutted by the movable member 2. Alternatively, the torsion spring 41 can be replaced by other structures (not shown in the figures) such as a C-shaped elastic sheet, wherein two ends of the C-shaped elastic sheet also abut against the pressing portion 33 and the fixed pressing portion 15 on the two sides of the pressing space 5 respectively to achieve the same effect as that of the torsion spring 41.

As shown in FIG. 6, friction pads 6 are further arranged on the first abutting surface 211 and the second abutting surface 311 respectively. Bodies of the friction pads 6 are fitted in interior sides of the first abutting surface 211 and the second abutting surface 311 respectively. Outer sides of the friction pads 6 facing towards the mounting opening 11 are arc-shaped concave surfaces which are positioned in front of the first abutting surface 211 and the second abutting surface 311 respectively so as to be more proximal to the mounting opening 11 than the first abutting surface 211 and the second abutting surface 311. According, friction between the first abutting surface 211 as well as the second abutting surface 311 and the shower head riser rail which may be smooth and glossy is enhanced, thereby improving the clamping effect A rotary positioning mechanism 50 is arranged between the socket 20 and the connecting end 141 of the fixed member 1. The rotary positioning mechanism 50 comprises a rotary disc 501 fixedly arranged on an end surface of the socket 20 facing towards the fixed member 1, and a spring positioning member 502 arranged on an end surface of the connecting end 141 of the fixed member 1. A circle of positioning holes 5011 are circumferentially arranged on the rotary disc 501. The spring positioning member 502 is movably inserted in a mounting hole 1412 on an end surface of the connecting end 141; the spring positioning member 502 comprises a positioning member 5021 and a positioning spring 5022; the positioning member 5021 is pressed by the positioning spring 5022 so as to be biased out of the mounting hole 1412 towards the positioning holes 5011, so that the spring positioning member 502 can be inserted into a corresponding positioning hole 5011 and fix a position of the socket 20 when the socket 20 rotates to different positions.

Furthermore, a lateral opening 2011 of the socket hole 201 of the socket 20 opens towards a direction perpendicular to an opening direction of the side opening 112 of the mounting opening 11 of the fixing seat 10, so as to reduce an action force applied to the opening direction of the side opening 112 when the handheld shower head is taken out, and this further reduces the probability of the shower head riser rail sliding out of the side opening 112.

Further, the first opening end 23 and the second opening end 35 are arranged to narrow the side opening 112, so that the shower head riser rail can be effectively prevented from sliding out of the side opening 112 due to lateral forces created when the handheld shower head is rotated, placed in position, or taken out. Specifically, when the socket 20 which holds the handheld shower head rotates, the fixed member 1 is subject to a torque in a way that the shower head riser rail will tend to be disengaged from the side opening 112 of the fixed member due to the torque, but since the movable member 2 and the pressing member 3 are cooperatively movable at two sides of the side opening 112, and a sliding direction of the movable member 2 is in fact perpendicular to a direction which the shower head riser rail tends to be disengaged from the side opening 112, the first opening end 23 and the second opening end 35 will not be easily affected by the torque in a way to move away from each other. Accordingly, the side opening 112 is kept narrowed by the first opening end 23 and the second opening end 35, and the shower head riser rail is prevented from disengagement from the side opening 112, thereby fully ensuring the clamping effect of the fixing seat 10 and effectively avoiding the slidable sleeve structure from falling off from the shower head riser rail during use.

In summary, according to the slidable sleeve structure of the present invention, the socket 20 is arranged to hold the handheld shower head; the fixing seat 10 is provided with the mounting opening 11; the mounting opening 11 is configured to accommodate the shower head riser rail which is inserted into the mounting opening 11 from a lateral side of the mounting opening 11; two sides of the mounting opening 11 are provided with the movable member 2 and the pressing member 3 which move towards or away from each other by cooperative rack and pinion mechanism achieved by the gear structure 341 and the rack structure 221; the elastic member 4 is used to bias the first abutting surface 211 of the movable member 2 and the second abutting surface 311 of the pressing member 3 to the close position where a circumferential wall of the shower head riser rail is clamped tightly; the friction pads 6 are used to increase the friction to prevent slippage; and the first opening end 23 and the second opening end 35 are arranged to narrow the side opening 112 to prevent slippage of the shower head riser rail from the side opening 112.

To remove the slidable sleeve structure of the present invention from the shower head riser rail, the fixed pressing portion 15 of the fixed member 1 and the pressing portion 33 of the pressing member 3 are held and pressed against each other by a hand of a user to compress the pressing space 5 so that the pressing portion 33 is brought close to the fixed pressing portion 15, thereby driving the movable member 2 and the pressing member 3 to the open position where the movable member 2 and the pressing member 3 move away from each other, and as such, the first abutting surface 211 and the second abutting surface 311 no longer clamp the shower head riser rail; the first opening end 23 and the second opening end 35 also move away from each other, so that the side opening 112 is widened to facilitate withdrawal of the slidable sleeve structure from the shower head riser rail; and the removed slidable sleeve structure can be quickly moved to any other position on the shower head riser rail and being fixed in position again.
