Description

Technical Field

[0001] The utility model relates to the field of household products, in particular to a pulley assembly, a sliding device and a shower room. Background Art

[0002] Existing shower rooms usually include a door body, a slide rail and a pulley assembly. During installation, the pulley assembly is usually installed on the slide rail first and then the door body is installed. The slide rail is provided with a slide groove and an inlet connected to the side wall of the slide groove. The pulley assembly includes a connector and a roller. The roller is inserted into the slide groove through the inlet, and most of the connector is located outside the slide groove. After the roller is installed, before the door body is installed, the operator usually needs to use his hands to keep the roller in a state. On the one hand, the reason is that the connector is a cantilever relative to the slide rail, and the gravity of the connector will cause the connector to rotate around the bottom of the slide groove to the outside of the inlet, thereby driving the roller to fall out of the inlet, and the roller needs to be reassembled, causing trouble. On the other hand, the operator uses at least one hand to keep the roller in a state, which is not conducive to lifting the door body to install the door body on the connector, making the installation efficiency low.

[0018] From the above description of the utility model and its preferred embodiments, it can be seen that, compared with the prior art, the technical solution of the utility model and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0019] 1. In the scheme 1 and its preferred embodiment, a pulley assembly is suitable for being installed on a slide rail, wherein the slide rail is provided with a slide groove and an insertion port communicating with the side wall of the slide groove; the pulley assembly comprises a connecting member, a roller and a rotation stopper. The connecting member is used to connect the door body. The roller is rotationally connected to the connecting member around an axis extending along a first direction; the roller is suitable for being inserted into the slide groove through the insertion port and rolling in the slide groove to reduce the friction force when the door body slides.

[0020] In the prior art, the above two accessories are usually provided. After the roller is installed, the operator usually needs to hold the roller in place with his hands. On the one hand, the connection piece is cantilevered relative to the slide rail, and the gravity of the connection piece will cause the connection piece to rotate, thereby driving the roller to fall out of the insertion opening, and the roller needs to be reassembled, causing trouble. On the other hand, the operator uses at least one hand to hold the roller in place, which is not conducive to lifting the door body to install the door body on the connection piece, making the installation efficiency low.

[0021] In this embodiment, the anti-rotation member includes a connecting portion and an abutting portion. The connecting portion is detachably connected to the connecting member, and the abutting portion extends along a first direction and toward the slide rail to be suitable for abutting against the slide rail. After the anti-rotation member is installed on the connecting member, if the connecting member rotates, the anti-rotation member will also rotate. However, since the abutting portion abuts against the slide rail, the anti-rotation member cannot rotate, and the connecting member cannot rotate either, thereby preventing the connecting member from rotating due to its own weight, causing the roller to escape from the insertion port. The operator can loosen the pulley assembly to operate the door body, which is convenient for operation and improves installation efficiency. After the installation is completed, the anti-rotation member will be removed from the connecting member to prevent excessive friction when the door body slides subsequently.

[0022] 2. In the second scheme and its preferred embodiment, the connecting portion and the connecting piece are plugged, snapped or screwed together to facilitate the installation and removal of the anti-rotation piece.

[0023] 3. In scheme three and its preferred embodiment, the connecting member is provided with a support platform, and the support platform is provided with a first surface and a second surface which are opposite to each other; the connecting part is provided with a slot, and the slot is suitable for being mounted on the support platform and making the slot wall of the slot abut against the first surface and the second surface, thereby completing the installation of the anti-rotation member and realizing the support of the anti-rotation member.

[0024] 4. In scheme 4 and its preferred embodiments, the slot is suitable for being plugged into the support table along a first direction and / or a direction perpendicular to the first direction and parallel to the horizontal plane, so as to be mounted on the support table; wherein, because the first direction is the direction pointing to the slide rail, a larger operating space may be required for plugging in, which makes installation inconvenient, while a direction perpendicular to the first direction and parallel to the horizontal plane requires a small operating space and is convenient for installation, and the operator can have a variety of installation options to improve installation efficiency.

[0025] 5. In scheme five and its preferred embodiments, the connecting member includes a first clamping member, a second clamping member and a locking member. The first clamping member is rotatably connected to the roller and is detachably connected to the connecting part; the locking member abuts against the second clamping member, and the locking member is suitable for passing through the second clamping member and being screwed to the first clamping member to adjust the distance between the first clamping member and the second clamping member. When the thickness of the door body is within a certain range, the first clamping member and the second clamping member can be close to both sides of the door body to complete the installation of the door body and prevent the installation from being impossible due to processing tolerances.

[0026] 6. In scheme six and its preferred embodiment, the first clamping member is provided with a resting surface and a supporting portion protruding from the resting surface. The resting surface is suitable for the door body to rest against, and the supporting portion is suitable for supporting the mounting hole sleeve on the door body. The supporting portion is provided with a threaded hole suitable for screwing with the locking member. The supporting portion is also used to lock with the locking member, and the structure is simpler.

[0027] 7. In scheme seven and its preferred embodiment, the anti-rotation member is made of a flexible material to allow deformation, so that the anti-rotation effect is better when abutting against the abutting surface, or at the same time, the abutting portion can be set to be longer, and abut against the slide rail after deformation, thereby reducing the situation where the abutting portion cannot touch the slide rail due to manufacturing tolerances.

[0028] 8. In scheme eight and its preferred embodiment, a sliding device includes a slide rail and the above-mentioned pulley assembly, the slide rail is provided with a slide groove and an inlet connected to the side wall of the slide groove, and the sliding device has the beneficial effects brought by the above-mentioned pulley assembly.

[0029] 9. In the ninth scheme and its preferred embodiment, after installation, the roller remains in a vertical state. Since the diameter of the roller is greater than the height of the insertion opening, when the door body is hit and jumps vertically upward, it cannot escape from the insertion opening, thus maintaining stability during use. Since the diameter of the roller is greater than the height of the insertion opening, the roller cannot enter the slide groove in a vertical state. Therefore, the height of the insertion opening should also be suitable for the roller to pass through the insertion opening in an inclined manner and be placed in the slide groove, thereby completing the installation of the roller.

[0030] 10. In scheme 10 and its preferred embodiment, a shower room includes a pulley assembly or a sliding device as described above, and the shower room has the beneficial effects brought by the pulley assembly or sliding device. BRIEF DESCRIPTION OF THE DRAWINGS

When the slot 411 can be inserted into the support platform 213 in both the first direction 6 and the second direction 7, the slot 411 is shown as having slots along the first direction 6 and the second direction 7. Figure 1 As shown. The abutting portion 42 extends along the first direction 6 and toward the slide rail 1 to be suitable for abutting against the abutting surface 13 of the slide rail 1, thereby preventing the connecting member 2 from rotating. The anti-rotation member 4 can be made of a flexible material to allow deformation, so that the anti-rotation effect is better when abutting against the abutting surface 13, or at the same time, the abutting portion 42 can be set longer, and abut against the slide rail 1 after deformation, thereby reducing the situation where the abutting portion 42 cannot touch the slide rail 1 due to manufacturing tolerance.

[0059] Then, the connector 2 and the roller 3 are installed under the door body 5, and they are matched with the slide rail 1 below, and the installation is completed. After the door body 5 is installed, the upper and lower rollers 3 both support the door body 5, and the door body 5 and the rollers are kept in a vertical state. At this time, the roller 3 cannot fall out of the insertion opening 12. Then, the anti-rotation member 4 is removed to prevent the door body 5 from having a large friction force when sliding.

The roller 3 is rotationally connected to the connecting member 2 around an axis extending along a first direction 6; the roller 3 is suitable for being inserted into the slide groove 11 through the insertion port 12 and rolling in the slide groove 11 to reduce the friction force when the door body 5 slides.

[0062] In this embodiment, the anti-rotation member 4 includes a connecting portion 41 and an abutting portion 42. The connecting portion 41 is detachably connected to the connecting member 2. The abutting portion 42 extends along the first direction 6 and toward the slide rail 1 to be suitable for abutting against the slide rail 1. After the anti-rotation member 4 is installed on the connecting member 2, if the connecting member 2 rotates, the anti-rotation member 4 will also rotate. However, since the abutting portion 42 abuts against the slide rail 1, the anti-rotation member 4 cannot rotate, and the connecting member 2 cannot rotate either, thereby preventing the connecting member 2 from rotating due to its own weight, causing the roller 3 to escape from the insertion port 12. The operator can loosen the pulley assembly to operate the door body 5, which is convenient for operation and improves installation efficiency. After the installation is completed, the anti-rotation member will be removed from the connecting member 2 to prevent excessive friction when the door body 5 slides subsequently.

[0063] In an exemplary embodiment, the connecting portion 41 is plug-connected, snap-connected, or screw-connected to the connecting member 2 to facilitate installation and removal of the anti-rotation member 4.

[0064] In an exemplary embodiment, the connecting member 2 is provided with a support platform 213, and the support platform 213 is provided with a first surface 2131 and a second surface 2132 which are opposite to each other; the connecting portion 41 is provided with a slot 411, and the slot 411 is suitable for being mounted on the support platform 213 and making the slot wall of the slot 411 abut against the first surface 2131 and the second surface 2132, thereby completing the installation of the anti-rotation member 4 and realizing the support of the anti-rotation member 4.

[0065] In an exemplary embodiment, the slot 411 is suitable for being plugged into the support platform 213 along the first direction 6 and / or the direction perpendicular to the first direction 6 and parallel to the horizontal plane, so as to be sleeved on the support platform 213; wherein, because the first direction 6 is the direction pointing to the slide rail 1, a larger operating space may be required during plugging, which makes installation inconvenient, while the direction perpendicular to the first direction 6 and parallel to the horizontal plane requires a small operating space and is convenient for installation, and the operator can have a variety of installation options to improve installation efficiency.

[0066] In an exemplary embodiment, the connecting member 2 includes a first clamping member 21, a second clamping member 22 and a locking member 23. The first clamping member 21 is rotatably connected to the roller 3 and is detachably connected to the connecting portion 41; the locking member 23 abuts against the second clamping member 22, and the locking member 23 is suitable for passing through the second clamping member 22 and being screwed to the first clamping member 21 to adjust the distance between the first clamping member 21 and the second clamping member 22. When the thickness of the door body 5 is within a certain range, the first clamping member 21 and the second clamping member 22 can be abutted against both sides of the door body 5 to complete the installation of the door body 5 and prevent the installation from being unable to be installed due to processing tolerances.

[0067] In an exemplary embodiment, the first clamping member 21 is provided with a resting surface 211 and a supporting portion 212 protruding from the resting surface 211. The resting surface 211 is suitable for the door body 5 to rest against, and the supporting portion 212 is suitable for supporting the mounting hole 51 on the door body 5.

[0068] In an exemplary embodiment, the anti-rotation member 4 is made of a flexible material to allow deformation, so that the anti-rotation effect is better when abutting against the abutting surface 13, or at the same time, the abutting portion 42 can be set to be longer, and abut against the slide rail 1 after deformation, thereby reducing the situation where the abutting portion 42 cannot touch the slide rail 1 due to manufacturing tolerances.

[0069] In an exemplary embodiment, a sliding device includes a slide rail 1 and the above-mentioned pulley assembly, the slide rail 1 is provided with a slide groove 11 and an inlet 12 connected to the side wall of the slide groove 11, and the sliding device has the beneficial effects brought by the above-mentioned pulley assembly.

[0070] In an exemplary embodiment, after installation, the roller 3 remains in a vertical state. Since the diameter of the roller 3 is greater than the height of the insertion opening 12, when the door body 5 is hit and jumps vertically upward, it cannot escape from the insertion opening 12, and the use process is kept stable. Since the diameter of the roller 3 is greater than the height of the insertion opening 12, the roller 3 cannot enter the slide groove 11 in a vertical state. Therefore, the height of the insertion opening 12 should also be suitable for the roller 3 to pass through the insertion opening 12 in an inclined manner and be placed in the slide groove 11, thereby completing the installation of the roller 3.
