Description

Technical Field

[0001] This utility model relates to the field of sliding door technology, specifically to a magnetic buffer guide wheel for sliding doors. Background Technology

[0002] During the movement of sliding doors, they are prone to colliding with the door frame due to inertia. Installing a buffer is the main way to solve the problem of inertial collisions. Since sliding doors need to slide in the track, the buffer needs to be small in size and needs to cooperate with the guide wheels to form a sliding buffer structure.

[0003] The invention disclosed in CN102536025A concerns a roller damper and gate assembly. The damper requires a complex structure, incorporating springs, hooks, and other components. Furthermore, springs are susceptible to metal fatigue and generate noise, resulting in a short service life for the damper.

[0004] Therefore, we propose a magnetic buffer guide wheel for sliding doors to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic buffer guide wheel for sliding doors to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnetic buffer guide wheel for sliding doors, comprising: a track, a hollow magnetic metal seat fixedly disposed at one end of the track, a linkage rod slidably disposed within the track, a guide wheel seat installed at one end of the linkage rod, and the guide wheel seat being fixedly connected to the sliding door;

[0007] A magnet head is installed at one end of the guide wheel seat, and the magnet head is magnetically inserted into the hollow magnetic metal seat.

[0008] The upper surface of the linkage rod is equipped with a buffer body, the buffer body is provided with a telescopic connecting rod, the end of the connecting rod is provided with a trigger head, and a toggle is fixedly installed at a predetermined position in the track, the toggle limiting the trigger head.

[0009] Preferably, the track is installed on the doorway, and the track has two symmetrical positioning track grooves and one trapezoidal groove.

[0010] Preferably, a secondary guide wheel is rotatably mounted at the other end of the linkage rod, and a primary guide wheel is mounted on the side of the guide wheel seat. The primary guide wheel and the secondary guide wheel are in rolling connection with the positioning track groove.

[0011] Preferably, a clip is installed on the upper surface of the hollow magnetic metal base, and a trapezoidal anti-detachment protrusion is integrally provided on the side of the clip, which is slidably embedded in the trapezoidal groove.

[0012] Preferably, the hollow magnetic metal base is further equipped with shaping supports at both ends, with the ends of the shaping supports abutting the four corners of the track.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When the gate needs to be closed, the gate pulls the main and auxiliary guide wheels towards the hollow magnetic metal base. The trigger head contacts the buffer actuator, and the connecting rod compresses the buffer body, starting the buffering process. At the same time, the magnet head approaches the hollow magnetic metal base, providing a magnetic attraction force opposite to the force of the buffer body. The buffer body plays a buffering role, while the magnet head plays an auxiliary closing role, maximizing the buffering performance, making it less prone to damage, and quieter.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a magnetic buffer guide wheel for sliding doors, comprising: a track 1, a hollow magnetic metal base 2 fixedly installed at one end of the track 1, a linkage rod 3 slidably installed inside the track 1, and the linkage rod 3 being fixedly connected to the sliding door.

[0022] Track 1 is installed on the door opening, and track 1 has two symmetrical positioning track grooves 11 and a trapezoidal groove 12.

[0023] A guide wheel seat 5 is installed at one end of the linkage rod 3, and a secondary guide wheel 4 is rotatably set at the other end of the linkage rod 3. A main guide wheel 51 is installed on the side of the guide wheel seat 5. The main guide wheel 51 and the secondary guide wheel 4 are rolledly connected to the positioning track groove 11 to realize the traction of the linkage rod 3 and the guide wheel seat 5 by the track 1.

[0024] A clip 21 is installed on the upper surface of the hollow magnetic metal base 2. The clip 21 has an integral trapezoidal anti-detachment protrusion on its side. The trapezoidal anti-detachment protrusion is embedded and slidably connected with the trapezoidal groove 12, so as to realize the anti-detachment function of the hollow magnetic metal base 2 and the track 1 at the same time.

[0025] Hollow magnetic metal base 2 is also equipped with shaping supports 22 at both ends. The ends of the shaping supports 22 abut against the four corners of the track 1 to position the hollow magnetic metal base 2 and stabilize it within the track 1.

[0026] A magnet head 53 is installed at one end of the guide wheel seat 5. The magnet head 53 is inserted into the hollow magnetic metal seat 2, and the magnet head 53 and the hollow magnetic metal seat 2 are magnetically connected.

[0027] A buffer body 6 is installed on the upper surface of the linkage rod 3. The buffer body 6 is provided with a telescopic connecting rod 61. A trigger head 62 is provided at the end of the connecting rod 61. A toggle 7 is fixedly installed at a predetermined position in the track 1. The toggle 7 limits the trigger head 62. The buffer is triggered by the buffer toggle 7 limiting the trigger head 62. The buffer is achieved by the connecting rod 61 pressing the buffer body 6.

[0028] Working principle: The buffer toggle 7 is installed on the predetermined position of the track 1, and then the shaping support 22 of the hollow magnetic metal seat 2 is inserted into the track 1. Then the trapezoidal anti-dislodgement protrusion of the clip 21 is embedded into the trapezoidal groove 12, and the hollow magnetic metal seat 2 is pushed to the appropriate position and fixed on the track 1 with screws.

[0029] Insert the guide wheel seat 5 into the track 1 from the other end of the track 1 to fix the track 1 on the door opening;

[0030] Then the swing gate is fixed on the guide wheel seat 5, so that the sliding of the swing gate can drive the guide wheel seat 5 to slide.

[0031] When the gate needs to be closed, the gate pulls the main and auxiliary guide wheels to move towards the hollow magnetic metal seat 2. The trigger head 62 contacts the buffer toggle 7, and the connecting rod 61 compresses the buffer body 6, starting the buffering. At the same time, the magnet head 53 approaches the hollow magnetic metal seat 2 and provides a magnetic attraction force opposite to the force of the buffer body 6. The buffer body 6 plays a buffering role, and the magnet head 53 plays an auxiliary closing role.

[0032] When the gate needs to be opened, the gate pulls the main and auxiliary guide wheels to move towards the auxiliary guide wheel 4. As the magnet head 53 moves away from the hollow magnetic metal seat 2, the magnetic force decreases, the buffer body 6 gradually gets rid of the restraint, and the buffer body pushes out the connecting rod 61 to assist the gate in opening.

[0033] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
