Description

Technical Field

[0001] The invention belongs to the technical field of shower room pulley structures, and particularly relates to an adjustable pulley structure for a shower room. Background Art

[0002] Traditional shower rooms mainly have two ways of opening doors, namely sliding doors and swing doors. Sliding doors are more widely used. The installation of sliding doors is mainly achieved by installing pulleys on the movable door and installing guide rails in the shower room. The pulleys slide back and forth on the guide rails to achieve the sliding and pulling of the glass door. During the sliding process of the pulleys on the rails, there will be up and down vibrations, which will cause the sliding door to be unable to move normally. In order to solve this problem, it is generally necessary to install an anti-jump device separately after the pulleys are installed on the guide rails, which increases the installation cost and also affects the overall aesthetics of the sliding door. In addition, the disassembly and assembly operations are relatively inconvenient.

[0003] The Chinese patent publication number is: CN218716047U, which discloses the patent name: A hidden anti-jump pulley assembly for a shower room, which relates to the technical field of shower room pulleys, including a front end body that slides with the shower room guide rail, and a rear end body for fixing the pulley assembly on the glass door. The rear end body is arranged at an interval with the front end body, and a pressure plate is provided between the rear end body and the front end body; the front end body includes a wheel hub that rolls with the shower room guide rail, a front cover plate arranged on one side of the wheel hub and slides with the shower room guide rail, and a rear cover plate arranged on the other side of the wheel hub.

[0004] Although it can meet the general usage requirements to a certain extent, in actual application, due to the door frame guide rail or under the action of gravity, the pulley assembly sags slightly, causing the pulley assembly to be unable to slide effectively. Therefore, the pulley assembly needs to be adjusted to ensure the stability of the connection with the door frame guide rail. The above technology cannot achieve adjustment operation, so its applicability and practicality are limited. Summary of the Invention

DETAILED DESCRIPTION

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] Example 1

[0049] See Figures 1 to 6 As shown, an adjustable pulley structure for a shower room includes a mounting structure 2 and a pulley assembly 1. The mounting structure is fixed to the mounting hole of the door leaf and is fixedly connected to the door leaf, while the pulley assembly is connected to the mounting structure and cooperates with the slide rail of the door frame to achieve sliding adjustment.

[0050] The mounting structure 2 includes a mounting seat 21, a pressure cover 22, a door leaf clamping structure 23, a mounting column 24, a worm gear transmission structure 25 and an adjusting screw 26; in this embodiment, the door leaf clamping structure is mainly used to clamp on the symmetrical side of the door leaf, and at the same time, the pressure cover cooperates with the mounting seat to position and fix the door leaf clamping structure, thereby ensuring the stability and reliability of the installation position.

[0051] In this embodiment, the mounting post 24 comprises a square cylinder 241 and a circular ring 242. The square cylinder has a circular protrusion 243, which is fitted over the protrusion. The pulley seat is attached to the side of the circular ring, and a screw passes through the pulley seat and the circular ring and is screwed into the circular protrusion. The circular ring facilitates the normal use of the pulley assembly and reduces friction between the pulley assembly and the mounting post.

[0052] The end surface of the mounting base is integrally formed with a raised block 4 containing an adjustment strip cavity 3. In this embodiment, the adjustment strip cavity is primarily used for positioning the mounting post. The post can also be adjusted within the adjustment strip cavity, providing cushioning during use. The mounting post is square in shape; the width of the square column matches the width of the adjustment strip cavity, and the length of the square column is smaller than the length of the adjustment strip cavity. The transverse perforations are arranged along the length of the adjustment strip cavity.

[0053] The raised block is provided with a transverse through-hole 5, and the raised block is provided with a vertical through-hole 6 connected with the transverse through-hole, and the vertical through-hole is arranged in the same direction as the axis of the pulley assembly; in this embodiment, the transverse through-hole and the vertical through-hole are arranged perpendicularly, and the transverse through-hole is mainly used for installing the worm transmission structure, while the vertical through-hole is mainly used for installing the adjusting screw; the adjusting screw is mainly used to adjust the worm transmission structure, thereby realizing the adjustment of the pulley assembly, and can also effectively prevent the automatic rotation of the adjusting screw caused by vibration during use, thereby avoiding the loosening and sagging of the door leaf; it is conducive to improving the stability and reliability of use.

[0054] During installation, the mounting post is arranged in the adjusting strip-shaped cavity, and the worm transmission structure is penetrated in the transverse through-hole; the adjusting screw is threadedly connected to the vertical through-hole, and the worm transmission structure is connected to the adjusting screw; the pulley assembly is fixed on the mounting post, and the adjustment operation of the pulley assembly can be realized through the adjusting screw; it is conducive to improving the convenience of adjustment, and because the position of the pulley assembly can be adjusted through the worm transmission structure when the adjusting screw rotates, the effectiveness and stability of the adjustment are improved.

[0055] At the same time, the gland is fixed to the mounting base by screws 7, and the door leaf clamping structure is arranged between the gland and the mounting base, and the door leaf is positioned in the door leaf clamping structure. The door leaf clamping structure cooperates with the gland and the mounting base to ensure the stability and reliability of the door leaf installation.

[0056] The worm drive structure 25 includes a stud 251 and a locking gear 252 fixed to the end of the stud. The stud is inserted into the transverse perforation, and the rack of the locking gear meshes with the threads of the adjustment screw. Due to the meshing of the adjustment screw and the locking gear, the adjustment screw cannot rotate due to vibration during use. This prevents the adjustment screw from automatically rotating due to vibration and causing the door leaf to loosen or sag, ensuring smooth operation and reliability, as well as accurate installation position. The adjustment screw rotates and, through the locking gear, enables the installation column to move and adjust within the adjustment bar cavity. However, the locking gear always meshes with the threads of the adjustment screw, improving smooth operation.

[0057] In this embodiment, a circular cavity 8 is provided on the side of the mounting base facing away from the pulley assembly; an adjustment disc 9 is disposed within the circular cavity; a circular recess 10 is provided on the side of the adjustment disc, and tooth grooves 11 are evenly distributed on the inner wall of the circular recess; a transmission gear 12 is fixed to the adjustment screw, located within the circular recess and meshing with the tooth grooves. The diameter of the transmission gear is smaller than the inner diameter of the circular recess. When the adjustment disc is rotated for adjustment, the transmission gear enables fine adjustment of the adjustment screw. Since the adjustment screw only rotates a small range when the adjustment disc rotates a large range, the fine adjustment can be improved. The pulley assembly can be finely adjusted through the adjustment screw and worm drive structure, improving precision and stability. Moreover, since the locking gear of the worm drive structure meshes with the tooth pattern of the adjustment screw, a locked state is achieved. During normal use, the adjustment screw will not rotate, ensuring the precision, stability and reliability of the operating position.

[0058] A decorative cover 13 is provided on the side of the mounting seat, and the screw passes through the mounting seat and is fixed to the decorative cover; an adjustment hole 14 is provided on the decorative cover; an adjustment nut 15 is fixed in the middle of the side of the adjustment disc, and the adjustment hole cooperates with the adjustment nut.

[0059] In this embodiment, it can be achieved by using a tool such as a screwdriver to pass through the adjustment hole and connect it to the adjustment nut. The adjustment nut drives the adjustment disc to rotate, and the tooth groove drives the transmission gear to move, thereby realizing the knob adjustment of the adjustment screw, thereby realizing the depth adjustment of the installation column in the adjustment bar cavity, that is, realizing the distance adjustment between the pulley assembly and the installation structure to meet the usage requirements of different situations.

[0060] The door leaf clamping structure 23 includes an inner plate 231 and an outer plate 232. The inner and outer plates are provided with a through hole 233 in the middle thereof, which matches the shape of the protruding block. The sides of the inner and outer plates are provided with a retaining ridge 234. During installation, the retaining ridges of the inner and outer plates snap onto the inner wall of the hole in the door leaf. The inner and outer plates abut against the symmetrical sides of the door leaf, respectively, and are pressed into position by the gland and mounting seat. This structure ensures stable installation of the inner and outer plates and the door leaf. In actual application, the inner and outer plates can be made of either plastic or metal.

[0061] The pulley assembly 1 includes a pulley seat 1-1, a bearing 1-2, and a pulley body 1-3. The pulley seat is fixed to the side of the mounting post via screws, and the pulley body is fixed to the pulley seat via bearings. To enhance the overall decorative performance, a protective cover 16 is snapped onto the end face of the pulley seat.

[0062] The structure of the present invention is reasonably set up. It is equipped with an installation structure, and the installation structure includes a mounting seat, a pressure cover, a door leaf clamping structure, a mounting column, a worm transmission structure and an adjusting screw. It can not only quickly realize the installation positioning with the door leaf, but also quickly realize the installation positioning with the door leaf. It realizes the adjustment locking limit through the worm transmission structure and the adjusting screw, which can effectively prevent the automatic rotation of the adjusting screw caused by vibration during use, thereby avoiding the loosening and sagging of the door leaf; it is conducive to improving the stability and reliability of use, and has strong applicability and good practicality.

[0063] Moreover, the adjustment disc cooperates with the transmission gear on the adjusting screw to improve the adjustment precision. During adjustment, when the adjusting disc rotates a large angle, the adjusting screw only rotates a small range, thereby improving the fineness of adjustment. When the pulley assembly sags or becomes loose after long-term use, the position of the pulley assembly can be adjusted by rotating the adjusting screw, thereby ensuring the stability and reliability of the use of the pulley assembly, and also helping to improve the accuracy, stability and reliability of the adjustment position.

[0064] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0065] Obviously, the above embodiments of the present invention are merely examples for the purpose of illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
