DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The utility model relates to a sliding device, which comprises an adjusting seat 100, a roller 200 and an adjusting component 300.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the roller 200 is mounted on the adjustment seat 100, and the roller 200 can rotate relative to the adjustment seat 100. The shape of the roller 200 is not limited, and can be a disc wheel, or an 8-wheel shape with a cross section narrow in the middle and wide at both ends. The surface of the roller 200 can be sleeved with an anti-slip rubber ring 210. The inside of the roller 200 is provided with a first cavity 201 and a second cavity 202. The first cavity 201 and the second cavity 202 are opened and connected along the axial direction of the roller 200. The first cavity 201 and the second cavity 202 pass through the roller 200 along the central axis of the roller 200. The radial cross-section of the first cavity 201 and the second cavity 202 can be set to a circle. A clamping wall 203 is provided at the connecting position of the first cavity 201 and the second cavity 202. The clamping wall 203 extends out along the radial direction of the first cavity 201 / the second cavity 202, and the clamping wall 203 can be set to a circular ring shape, or a semi-ring shape, a protrusion distributed along the circumference, and the like. The center of the clamping wall 203 is hollow, and the first cavity 201 and the second cavity 202 are connected through the center of the clamping wall 203. The adjustment component 300 is arranged in the first cavity 201 and the second cavity 202. A part of the adjustment component 300 extends out of the first cavity 201 or the second cavity 202 and is connected to the adjustment seat 100. The adjustment component 300 and the adjustment seat 100 are relatively fixed in the rotation direction of the roller 200, that is, the adjustment component 300 cannot rotate relative to the adjustment seat 100. When the roller 200 rotates relative to the adjustment seat 100, the roller 200 will also rotate relative to the adjustment component 300. The part of the adjustment component 300 extending into the first cavity 201 and the second cavity 202 will pass through the central hollow position of the clamping wall 203. The adjustment component can clamp the axial two sides of the clamping wall 203, that is, the adjustment component 300 abuts on the two side sides of the clamping wall 203 facing the first cavity 201 and the second cavity 202 respectively. The adjusting assembly 300 has a clamping force on the clamping wall 203, and the adjusting assembly 300 can adjust the clamping force on the clamping wall 203. When the roller 200 is subjected to an external force, the roller 200 will rotate relative to the adjusting seat 100. During the rotation of the roller 200, the clamping force of the adjusting assembly 300 on the clamping wall 203 also generates sliding damping on the roller 200. Changing the magnitude of the clamping force can change the magnitude of the sliding damping on the roller 200, thereby changing the rotation speed of the roller 200 when subjected to an external force. In actual use, the sliding device can be applied to products such as shower equipment and shower heads. For example, the sliding device is installed on a lifting seat of the shower equipment, and the lifting seat is installed on a guide rod of the shower equipment, and the lifting seat can be lifted and lowered relative to the guide rod. The roller 200 of the sliding device abuts against the guide rod of the shower equipment. When the lifting seat is pushed by the user to lift and lower, the roller 200 rolls on the guide rod. After the lifting seat loses the external force, the lifting seat is positioned at the current height of the catheter by utilizing the friction between the roller 200 and the guide rod and the friction between the adjustment assembly 300 and the clamping wall 203 .By controlling the clamping force of the adjusting component 300 on the clamping wall 203, that is, changing the sliding damping of the roller 200, the external force required by the user to push the lifting seat can be controlled to meet the different usage requirements of the user. Different appliances can be hung on the lifting seat, such as a shower head. According to the total weight of the hanging appliances and the lifting seat, the clamping force is adjusted to ensure the stability of the lifting seat in the current position. The application of the sliding device makes the lifting process of the lifting seat very smooth. The same external force is used to push at any height, and no button operation is required, which is very convenient. After long-term use, the roller 200 will age. The clamping force of the adjusting component 300 on the clamping wall 203 can be readjusted to the appropriate sliding damping. It is easy to use, greatly reduces the impact of aging problems on the use of the roller 200, and increases the service life of the sliding device.

[0035] The adjustment component 300 may adopt an elastic pressure structure, for example, an elastic structure is used to cooperate with a pressure seat to elastically clamp the clamping wall 203, and the clamping force is adjusted by adjusting the elastic force of the elastic structure. The adjustment component 300 may also adopt a component that moves along the axial direction of the roller 200, and the clamping force on the clamping wall 203 is changed by controlling the opening and closing position. In some embodiments of the utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the adjustment assembly 300 includes a bushing 310, a washer 320, an elastic member 330 and a locking member 340. The circumferential profile of the bushing 310 can be set to a circle, and the radial cross-sections of the first cavity 201 and the second cavity 202 are set to a circle. The bushing 310 is installed in the first cavity 201, and the washer 320 is installed in the second cavity 202. The bushing 310 abuts against the end surface of the clamping wall 203 facing the first cavity 201, and the washer 320 abuts against the end surface of the clamping wall 203 facing the second cavity 202. The locking member 340 extends into the first cavity 201 and the second cavity 202, and passes through the bushing 310, the clamping wall 203 and the washer 320. The locking member 340 is connected to the elastic member 330, one end of the locking member 340 can be fixed on one of the bushing 310 and the washer 320, and the elastic member 330 abuts between the other of the bushing 310 and the washer 320 and the other end of the locking member 340. The locking member 340 rotates relative to the bushing 310 and the washer 320 to compress the elastic member 330 against the bushing 310 / waster 320 abutting therewith, thereby increasing the clamping force of the washer 320 and the bushing 310 on the clamping wall 203.

[0036] Specifically, the elastic member 330 may be a spring 331. The locking member 340 includes a screw 341 and a nut 342. The screw 341 extends from the end of the first cavity 201 into the first cavity 201, and the screw 341 passes through the bushing 310, the clamping wall 203 and the washer 320 in the axial direction. The nut of the screw 341 is retained in the first cavity 201, and the end of the screw 341 extending into the washer 320 is installed with the nut 342. The nut 342 is fixed in the washer 320, and the nut 342 may be fixed in the washer 320 by gluing, or the washer 320 may be provided with an inner hexagonal cavity matching the shape of the nut 342, and the nut 342 is fixed in the washer 320 by clamping, so that the nut 342 and the washer 320 will not rotate relative to each other. The end of the screw 341 is threadedly connected to the nut 342. The spring 331 is sleeved on the screw 341 and retained in the first cavity 201. One end of the spring 331 abuts on the nut, and the other end abuts on the bushing 310. When the screw 341 is turned, the screw 341 moves axially in the first cavity 201. The spring 331 is supported by the nut and presses the bushing 310 toward the clamping wall 203. The bushing 310 is pressed toward the clamping wall 203 by the nut 342, and the bushing 310 and the washer 320 clamp the clamping wall 203. The greater the compression deformation of the spring 331 by the screw 341, the greater the clamping force of the bushing 310 and the washer 320 on the clamping wall 203. Conversely, the smaller the compression deformation of the spring 331 by the screw 341, the smaller the clamping force of the bushing 310 and the washer 320 on the clamping wall 203. When the screw 341 needs to be adjusted, it is only necessary to use a tool to reach into the first cavity 201 and rotate the screw 341 to adjust it. The adjustment component 300 is concealedly installed in the roller 200, effectively reducing space occupation.

[0037] In some embodiments of the present invention, Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, when the roller 200 rotates, the bushing 310 and the washer 320 will not rotate relative to the adjustment seat 100. A sliding structure is provided between the bushing 310 and the washer 320. The sliding structure passes through the clamping wall 203, and the bushing 310 and the washer 320 are axially connected by the sliding structure. The bushing 310 and the washer 320 can move relative to each other in the axial direction by using the sliding structure. When the spring 331 is compressed or elastically reset, the bushing 310 and the washer 320 can be relatively close to or away from each other, thereby increasing or reducing the clamping force on the clamping wall 203. At the same time, the sliding mechanism limits the relative rotation between the bushing 310 and the washer 320.

[0038] The sliding connection structure can be that a slot is set in one of the bushing 310 and the washer 320, and the other is inserted into the slot for sliding connection. Alternatively, a sliding rod is set between the bushing 310 and the washer 320, and the radial cross section of the sliding rod is polygonal. The sliding rod passes through the bushing 310 and the washer 320, so that the washer 320 and the bushing 310 can move relative to each other in the axial direction but cannot rotate relative to each other. The link structure can also be other structural forms. In this embodiment, if Figure 7 and Figure 8 As shown, the bushing 310 is provided with a plurality of plug posts 311, which are sequentially distributed along the circumference of the bushing 310, and the plug posts 311 extend along the axial direction of the bushing 310, and the axial direction of the bushing 310 is consistent with the axial direction of the roller 200. The washer 320 is provided with a plurality of slide grooves 321, which are sequentially distributed along the circumference of the washer 320. Each slide groove 321 extends along the axial direction of the washer 320, and the axial direction of the washer 320 is consistent with the axial direction of the roller 200. The bushing 310 is placed in the first cavity 201, and the washer 320 is placed in the second cavity 202. The plug posts 311 can be passed through the clamping wall 203 and then matched with the slide grooves 321 one by one for axial insertion, or the washers 320 can be passed through the clamping wall 203 and matched with the plug posts 311 one by one for axial insertion. The insert column 311 and the slide groove 321 cooperate to form a sliding structure, so as to achieve relative adjustment of the axial positions of the bushing 310 and the washer 320 and restrict the relative rotation of the bushing 310 and the washer 320.

[0039] The adjustment assembly 300 cannot rotate relative to the adjustment seat 100. A limiting member may be provided on the adjustment seat 100. The limiting member extends from the first cavity 201 or the second cavity 202 and is then fixed to the adjustment seat 100 by plugging, clamping, locking, etc. In some embodiments of the present invention, Figure 4 , Figure 5 and Figure 7 As shown, the outer contour of the gasket 320 is a polygon, which can be a triangle, a quadrilateral, a pentagon, a hexagon, etc. The adjustment seat 100 is provided with a polygonal hole 101, which can be a triangle, a quadrilateral, a pentagon, a hexagon, etc. The gasket 320 is inserted into the polygonal hole 101 and the second cavity 202, that is, a part of the ring body of the gasket 320 extends into the second cavity 202, and a part of the ring body extends into the polygonal hole 101. The ring body of the gasket 320 extending into the second cavity 202 abuts against the end surface of the clamping wall 203, and at the same time cooperates with the adjustment component 300 to limit the axial movement of the gasket 320. The outer contour shape of the gasket 320 is adapted to the shape of the polygonal hole 101, and the polygonal hole 101 limits the rotation of the gasket 320 relative to the adjustment seat 100, thereby limiting the rotation of the adjustment component 300 relative to the adjustment seat 100. The maximum outer diameter of the gasket 320 is smaller than the inner diameter of the second cavity 202 . When the roller 200 rotates, the second cavity 202 can rotate relative to the gasket 320 .

[0040] In some specific embodiments of the present invention, Figure 6 and Figure 7 As shown, the clamping wall 203 extends in a circular shape. The interior of the roller 200 is separated into a first cavity 201 and a second cavity 202 by the clamping wall 203 as a boundary. A plurality of recesses 204 are provided on at least one end surface of the clamping wall 203. The plurality of recesses 204 may be provided on the end surface of the clamping wall 203 facing the first cavity 201, or on the end surface of the clamping wall 203 facing the second cavity 202, or on both side end surfaces of the clamping wall 203. Each recess 204 is sequentially distributed around the rotation axis of the roller 200. The recess 204 may be concave in an arc surface. A protrusion 301 is provided on the surface of the adjusting component 300 that contacts the clamping wall 203. When the recess 204 is provided on the end surface of the clamping wall 203 facing the first cavity 201, the protrusion 301 is provided on the end surface of the bushing 310 facing the clamping wall 203. When the recess 204 is arranged on the end surface of the clamping wall 203 facing the second cavity 202, the protrusion 301 is arranged on the end surface of the gasket 320 facing the clamping wall 203. The protrusion 301 faces the recess 204, and when the roller 200 rotates, the adjustment component 300 rotates relative to the roller 200. When the recess 204 rotates with the roller 200 to be opposite to the protrusion 301, the protrusion 301 will slide into the recess 204. Then, as the roller 200 continues to rotate, the recess 204 and the protrusion 301 will gradually be misaligned, and the protrusion 301 will slide out of the recess 204, and the protrusion 301 will abut on the end surface of the clamping wall 203 where the recess 204 is located. Then, it will continue to slide into the next recess 204 as the roller 200 rotates. Through the cooperation of the protrusion 301 and the recess 204, the friction between the adjustment component 300 and the clamping wall 203 is further increased. At the same time, when the roller 200 rotates, a "ticking" prompt sound will be heard during the process of the protrusion 301 sliding in and out of the recess 204.

[0041] In some specific embodiments of the present invention, Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, connecting parts 110 extend from opposite sides of the adjustment seat 100. Two connecting parts 110 are located at the axial ends of the roller 200. Circular grooves 111 are provided on the opposite surfaces of the connecting parts 110 on both sides. Convex shafts 205 are provided on both sides of the roller 200. The convex shafts 205 on both sides are coaxially arranged around the ends of the first cavity 201 and the second cavity 202 respectively. The convex shafts 205 are paired and inserted into the circular grooves 111 one by one. The connecting parts 110 on both sides limit the axial position of the roller 200, and the convex shafts 205 and the circular grooves 111 are rotated together to realize the rotation of the roller 200 on the adjustment seat 100. The adjustment assembly 300 mainly limits the axial position of the roller 200 and provides rotation damping. A through hole 112 is provided on the connecting portion 110, and the first cavity 201 and the second cavity 202 are connected to the outside through the through hole 112. When adjusting the adjustment assembly 300, a tool can pass through the through hole 112 and then extend into the first cavity 201 or the second cavity 202 for operation. The polygonal hole 101 is the through hole 112 relative to the second cavity 202.

[0042] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the sliding device also includes a sliding seat 410, a branch pipe 420 and a pusher 430. A sliding cavity 411 is provided inside the sliding seat 410. In this embodiment, the sliding cavity 411 can be vertically arranged and penetrate the sliding seat 410. The lifting seat in the above embodiment is one embodiment of the sliding seat 410. The branch pipe 420 is penetrated in the sliding cavity 411, and the guide rod in the above embodiment is one embodiment of the branch pipe 420. The sliding seat 410 slides relatively along the branch pipe 420. The adjustment seat 100 is mounted on the sliding seat 410. The roller 200 abuts against the branch pipe 420. When the adjustment seat 100 moves relative to the sliding seat 410, the roller 200 can be driven to move relative to the branch pipe 420 in a direction close to or away from the branch pipe 420. The pusher 430 is mounted on the sliding seat 410, and the pusher 430 can use the cooperation of the adjustment screw 431 and the connecting seat 432. The connecting seat 432 is slidably connected to the adjusting seat 100. A slide rail may be provided inside the connecting seat 432. The adjusting seat 100 is slidably connected to the slide rail. The adjusting seat 100 may move relative to the connecting seat 432, and then the adjusting seat 100 moves relative to the sliding seat 410. The adjusting screw 431 is rotatably mounted on the connecting seat 432. The adjusting screw 431 pushes the adjusting seat 100 to move, thereby controlling the pressure of the roller 200 against the branch pipe 420, and then controlling the friction between the roller 200 and the branch pipe 420. When the sliding seat 410 slides along the branch pipe 420, the roller 200 rolls on the branch pipe 420. When the roller 200 or the anti-skid rubber ring 210 sleeved on its surface ages after long-term use, the damping of the roller 200 relative to the branch pipe 420 when rolling is effectively adjusted through the cooperation of the pushing member 430 and the adjusting assembly 300.
