Description

Technical Field

[0001] This utility model belongs to the field of bathroom clamp technology, specifically relating to a hydraulic three-hole large bathroom clamp. Background Technology

[0002] As the core connecting and opening / closing control component of glass bathroom doors, the performance of bathroom clamps directly determines the safety, comfort, and lifespan of the bathroom door. They are widely used in various scenarios such as home bathrooms, hotel bathrooms, and public bathhouses. With the development of the modern building decoration industry, consumers' demands for the aesthetics, transparency, and space utilization of bathroom spaces are constantly increasing. Large, heavy-duty glass doors, due to their advantages of visual openness and high-end texture, are increasingly used in various bathroom scenarios. Correspondingly, this places higher demands on the load-bearing capacity and opening / closing buffer performance of suitable bathroom clamps. Traditional bathroom clamps are mostly designed for small and medium-sized lightweight glass doors. Traditional bathroom clips typically employ a single small spring or simple damping component as their core buffer structure, resulting in limited buffering force and insufficient stability. When applied to large, heavy-duty glass doors, the traditional structure's buffering capacity is insufficient to effectively counteract the door's kinetic energy due to the door's heavy weight and strong inertia during opening and closing. This can easily lead to excessively fast closing speeds and violent collisions between the door and the frame. Such collisions not only generate harsh noises, affecting the user experience, but also cause structural damage to the door glass, frame, and the clip itself, shortening the product's lifespan. In severe cases, uneven stress on the glass door can even cause it to shatter, posing a significant safety hazard. Utility Model Content

[0003] The purpose of this utility model is to provide a hydraulic three-hole large bathroom clamp to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic three-hole bathroom clamp, comprising:

[0005] A first clamping plate, and a second clamping plate is provided on one side of the first clamping plate;

[0006] The main body is rotatably connected between the first clamping plate and the second clamping plate via a rotating shaft. One end of the main body is connected to a mounting plate. The main body contains a spring column and hydraulic buffers are located on both sides of the spring column. One end of the hydraulic buffer is connected to the mounting plate. When the rotating shaft rotates, it can drive the spring column to generate elastic deformation to store reset potential energy. At the same time, the hydraulic buffers on both sides synchronously play a damping buffering role to realize the slow closing of the bathroom clamp.

[0007] Preferably, a short rod is connected to the middle of the mounting plate, and one end of the short rod slides through the bottom of the spring column. One end of the short rod inside the spring column is connected to a spring, and the other end of the spring is connected to the spring column. Through the guidance of the short rod and its cooperation with the built-in spring, the deformation stability of the spring column is enhanced, and the reserve of reset potential energy and the reset reliability are improved.

[0008] Preferably, the middle part of the rotating shaft is connected to an arc-shaped protrusion for pushing the spring column to produce elastic deformation when rotating. Through the arc-shaped protrusion structure, the rotating shaft can smoothly push the spring column to deform when rotating, avoiding stress concentration and ensuring smooth potential energy storage.

[0009] Preferably, the two ends of the rotating shaft are connected to locking blocks, and one end of the locking block rotates through the main body. The locking blocks at both ends axially limit the rotating shaft to prevent axial movement when the rotating shaft rotates and ensure the stability of the rotating shaft center.

[0010] Preferably, a rolling bearing is provided at the rotation point between the locking block and the main body to convert sliding friction into rolling friction, reduce wear between the locking block and the main body, improve the smoothness of shaft rotation, and extend service life.

[0011] Preferably, the first clamping plate is connected to a mounting bracket, and the mounting bracket is provided with screw cylinders on both sides of the top of the mounting bracket. The mounting bracket provides a mounting base for the rotating shaft assembly, and the screw cylinders are used to achieve a firm connection with the second clamping plate.

[0012] Preferably, the second clamping plate is provided with two sets of mounting holes. The second clamping plate is screwed to the screw sleeve in the first clamping plate by screws passing through the mounting holes. The screw connection between the mounting holes and the screw sleeve realizes a detachable and firm connection between the two clamping plates, ensuring clamping stability.

[0013] Preferably, the mounting bracket has locking holes at both ends and locking blocks are rotatably connected to the locking holes. The locking holes and locking blocks cooperate to form a double radial limit, which further ensures the axial stability of the rotating shaft during long-term rotation and avoids deviation and jamming.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The dual hydraulic buffer symmetrical layout design is adopted. Compared with the traditional single buffer structure, the buffer force is significantly enhanced. The symmetrical arrangement ensures that the force on the door remains balanced during the closing process, avoiding problems such as tilting and jamming when the door is opened and closed due to excessive buffer force on one side. The damping force generated by the hydraulic buffer through the oil flow restriction is stable and controllable, which can continuously offset the inertial kinetic energy of the heavy door. It completely solves the problems of the door closing too fast and violent collision between the door and the door frame caused by insufficient buffering in traditional bathroom clamps. It effectively eliminates collision noise and avoids structural damage to the door glass, door frame and bathroom clamp itself caused by rigid impact, greatly improving the safety and comfort during use.

[0016] (2) The elastic reset structure with spring column and built-in spring can store more reset potential energy, ensuring that the door can obtain a stable reset driving force after opening regardless of the opening angle, and achieve complete closure. At the same time, the hydraulic buffer plays a damping role during the reset process, effectively suppressing the rapid rebound of the door caused by excessive elastic reset force, so that the reset process is also smooth and stable, avoiding secondary collision between the door and the door frame during reset. In addition, the precise guiding effect of the short rod on the spring column prevents the spring column from deflecting or jamming during deformation and reset, further improving the operational reliability of the reset structure.

[0017] (3) The locking blocks at both ends of the rotating shaft form a precise radial limiting fit with the locking holes of the mounting bracket, ensuring that the rotating shaft remains stable during long-term rotation and avoiding local force concentration caused by shaft offset. At the same time, rolling bearings are added at the rotating connection between the locking blocks and the main body, which transforms the easily worn sliding friction in the traditional structure into rolling friction, greatly reducing the wear of components during rotation and reducing the occurrence rate of failures such as rotation jamming and abnormal noise caused by wear.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0025] This utility model provides, for example Figure 1-4 The hydraulic three-hole bathroom clamp shown includes:

[0026] The first clamping plate 1 is used to clamp one side of the glass door to achieve the initial connection and positioning of the door body and the door frame. A second clamping plate 2 is provided on one side to clamp the other side of the glass door. The two clamping plates cooperate to form a stable clamping structure for the glass door.

[0027] The main body 3 serves as the core mounting and transmission carrier, and is rotatably connected between the first clamping plate 1 and the second clamping plate 2 via a rotating shaft 4, enabling the relative rotation of the two clamping plates around the rotating shaft to complete the opening and closing action of the door. One end of the main body 3 is fixedly connected to a mounting plate 5 for mounting buffer and reset components. The main body 3 is equipped with a spring column 6 for providing reset driving force, and hydraulic buffers 7 for providing damping buffer force are symmetrically arranged on both sides of the spring column 6. One end of the hydraulic buffer 7 is fixedly connected to the mounting plate 5 to achieve positioning support.

[0028] When the door opens and closes, it drives the pivot 4 to rotate. The pivot 4 synchronously drives the spring column 6 to generate axial compression deformation to store the elastic potential energy required for the door to reset. At the same time, the hydraulic buffers 7 on both sides generate damping effect under the action of the pivot 4. Through the oil flow restriction, a stable and controllable buffer force is formed. This works in conjunction with the elastic force of the spring column 6 to realize that the bathroom clamp drives the door to close slowly and smoothly, avoiding rigid collision between the door and the door frame.

[0029] A short rod 8 for guiding and limiting the spring column 6 is fixedly connected to the middle of the mounting plate 5. One end of the short rod 8 slides through the bottom of the spring column 6 along the axial direction, ensuring that the spring column 6 deforms only in the axial direction and does not shift laterally. A spring 9 is fixedly connected to one end of the short rod 8 inside the spring column 6. The other end of the spring 9 is fixedly connected to the inner wall of the spring column 6. The spring 9 and the spring column 6 form an elastic reset structure, which enhances the reserve of reset potential energy and improves the stability and reliability of the reset action.

[0030] The rotating shaft 4 has an integrally formed arc-shaped protrusion 10 in the middle. The curved surface profile of the arc-shaped protrusion 10 is adapted to the end face of the spring column 6. It is used to push the spring column 6 to produce axial elastic deformation in a progressive extrusion manner during the rotation of the rotating shaft 4. The curved surface contact reduces the stress concentration during the extrusion process, ensuring that the spring column 6 deforms uniformly and is subjected to stable force.

[0031] The two ends of the rotating shaft 4 are symmetrically fixedly connected with locking blocks 11. One end of the locking block 11 rotates through the main body 3 and extends into the first clamping plate 1 to limit the axial position of the rotating shaft 4 and prevent the rotating shaft 4 from moving axially during rotation. At the same time, the cooperation structure between the locking block 11 and the main body 3 forms radial support for the rotating shaft 4 to ensure the stability of the rotating shaft 4's rotation axis.

[0032] A rolling bearing 12 is nested at the rotatable connection between the locking block 11 and the main body 3. The inner ring of the rolling bearing 12 is interference-fitted with the locking block 11, and the outer ring is fixedly connected to the main body 3. This is used to convert the sliding friction between the locking block 11 and the main body 3 into rolling friction, which greatly reduces the rotational resistance and component wear, improves the smoothness of the rotation of the shaft 4, and extends its service life.

[0033] The first clamping plate 1 is internally fixedly connected to a mounting bracket 13 for mounting the rotating shaft assembly. The mounting bracket 13 serves as a support carrier for the rotating shaft 4. Screw cylinders 14 are symmetrically arranged on both sides of its top for fixing the two clamping plates. The inner wall of the screw cylinder 14 is provided with internal threads, which cooperate with the fixing screws to form a reliable threaded connection structure, ensuring that the first clamping plate 1 and the second clamping plate 2 are firmly connected.

[0034] The second clamping plate 2 has two sets of mounting holes 15 at the positions corresponding to the screw cylinder 14. The mounting holes 15 are through-hole structures with smooth inner walls for the screws to pass through. The second clamping plate 2 is screwed to the screw cylinder 14 in the first clamping plate 1 by screws passing through the mounting holes 15, so as to realize the detachable connection of the two clamping plates, which is convenient for installation, maintenance and replacement. At the same time, the symmetrical arrangement of the two sets of mounting holes 15 ensures that the connection is evenly stressed.

[0035] The mounting bracket 13 has locking holes 16 at both ends corresponding to the locking blocks 11. The diameter of the locking holes 16 is adapted to the outer diameter of the locking blocks 11. The locking blocks 11 are rotatably connected to the inside of the locking holes 16, forming a double radial limiting structure for the rotating shaft 4. This further ensures that the shaft center position of the rotating shaft 4 is stable during long-term rotation, avoiding door opening and closing jamming or component damage caused by shaft offset.

[0036] This hydraulic three-hole bathroom clamp relies on the synergistic linkage of a mechanical elastic structure and a hydraulic damping structure to achieve a smooth and controllable opening and closing process for the glass door. The entire operation process can be divided into a closing buffer stage and an opening reset stage. The synchronous cooperation of each component ensures operational stability. During the closing stage, when the user pushes the glass door to gradually close it, the first clamp 1 or the second clamp 2, which is fixedly connected to the door, will rotate accordingly, thereby driving the rotating shaft 4 that runs through the clamps to rotate synchronously. The arc-shaped protrusion 10 integrally formed in the middle of the rotating shaft 4 will gradually contact the end face of the spring column 6 inside the main body 3 and generate a squeezing effect as the rotating shaft rotates. Due to the arc-shaped protrusion 10 Due to the curved surface structure of the 0, the compression process generates a gradual pressure transmission, forcing the spring column 6 to undergo axial compression deformation along the axis of the short rod 8 fixed on the mounting plate 5. The short rod 8 plays a precise guiding role in this process, preventing the spring column 6 from shifting laterally. At the same time, the spring 9 nested inside the spring column 6 will contract synchronously with the compression of the spring column, converting the kinetic energy during the closing process into elastic potential energy for storage. While the spring column 6 is compressing and deforming, the hydraulic buffers 7 symmetrically arranged on both sides of it will be synchronously squeezed by the two ends of the rotating shaft 4. The piston inside the hydraulic buffer 7 begins to move under the pressure, and the hydraulic oil filled inside can only pass through the internally preset flow restriction under the squeezing action of the piston. The hydraulic oil flows slowly, and during this process, the friction between the hydraulic oil and the channel wall, as well as the internal friction between oil molecules, together form a stable and controllable damping force. This damping force, together with the elastic reaction force generated by the spring column 6 and the spring 9, works synergistically to continuously counteract the kinetic energy generated by the door's own weight and pushing inertia, causing the door's rotation speed to gradually decrease, ultimately achieving a slow, impact-free closure. During the opening phase, when the user pulls the door to open it, the external force causes the first clamping plate 1 or the second clamping plate 2 to rotate in the opposite direction. The rotating shaft 4 and the arc-shaped protrusion 10 also rotate in the opposite direction. The squeezing pressure of the arc-shaped protrusion 10 on the spring column 6 is gradually released. At this time, the elastic potential energy stored in the spring column 6 and the internal spring 9 begins to be released. The spring column 6 is pushed to return to its original position along the axis of the short rod 8, while the piston of the hydraulic damper 7 moves in the opposite direction. The hydraulic oil flows back to the initial position through the flow-limiting channel. The hydraulic damper 7 also plays a damping role in this process to prevent the door from opening too fast. In addition, the locking blocks 11 fixed at both ends of the rotating shaft 4 are always embedded in the locking holes 16 of the mounting bracket 13, forming a radial limit on the rotation trajectory of the rotating shaft. At the same time, the rolling bearing 12 set at the rotation connection between the locking block 11 and the main body 3 converts the sliding friction when the rotating shaft rotates into rolling friction, which greatly reduces the rotational resistance and avoids component wear, ensuring that the entire door opening process is also smooth and stable, and preparing the structure for the next door closing buffer.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
