Abstract
Description
Technical Field
[0001] This utility model relates to the field of track wheel technology, specifically to a device with an anti-detachment structure. Background Technology
[0002] The sliding door track rollers are a key component for the movement of sliding doors. They typically occupy little space and can move laterally, making them widely used in various locations. The track rollers are usually installed on the bottom side of the door, where guide rails are installed for connection and coordination, allowing the door to move smoothly along the track. However, sliding door structures created using this method are susceptible to damage from the external environment and pebbles and dust on the guide rails, which can lead to roller damage and affect the subsequent use of the sliding door. Therefore, a nested structure has gradually emerged, where the track rollers are installed on the bottom side of the sliding door and connected to the ground. The nested structure on the bottom side of the sliding door then wraps around the track rollers, reducing their contact with the external environment and minimizing damage.
[0003] When a sliding door uses a nested structure to enclose the track wheels, the pulleys on both sides of the sliding door are easily damaged by the collision of the nested structure, which can cause the track wheels to detach from the sliding door.
[0004] Therefore, a device with an anti-detachment structure is proposed to solve the problem that the track wheels are easily damaged by collisions during use, causing them to detach from the sliding door. Utility Model Content
[0005] The technical problem to be solved by this utility model is that the track wheels are easily damaged by collisions during use, which leads to the track wheels detaching from the sliding door. Therefore, a device with an anti-detachment structure is proposed.
[0006] The technical solution adopted by this utility model to solve the technical problem is: a device with an anti-detachment structure, including a support plate, the support plate being fixedly connected to the contact surface by bolts, a support frame being welded to the upper end of the support plate, a connecting plate being rotatably connected to the upper side of the support frame via a rotating shaft, pulleys being rotatably connected to both sides of the upper end of the connecting plate, baffles being contacted on both sides of the pulleys, and ball bearings being rotatably embedded on both sides of the baffles, a positioning rod being threadedly connected to one side of the connecting plate, a protrusion being fixedly connected to one side of the positioning rod, and the positioning rod being sleeved on the baffle.
[0007] As a preferred technical solution of this utility model, cleaning brushes are fixedly connected to both sides of the baffle. The cleaning brushes are composed of bristles. By setting the cleaning brushes, the nested structure on the bottom side of the sliding door can be cleaned.
[0008] As a preferred technical solution of this utility model, a reinforcing rib is fixedly connected to one side of the baffle, and one side of the reinforcing rib contacts the connecting plate. By setting the reinforcing rib, the stability of the connection between the baffle and the connecting plate can be increased.
[0009] As a preferred technical solution of this utility model, a pad is fixedly connected to one side of the baffle. The pad is made of rubber material. The pad increases the buffer between the baffle and the two sides of the sliding door.
[0010] As a preferred technical solution of this utility model, a gasket is in contact with one side of the baffle, and the gasket is sleeved with the positioning rod. By setting the gasket, the stability of the connection between the positioning rod and the connecting plate is increased.
[0011] As a preferred technical solution of this utility model, a hidden groove is provided on one side of the baffle, and the protrusion of the positioning rod is located in the hidden groove. By setting the hidden groove, it is possible to prevent the nested structure at the bottom of the sliding door from directly colliding with the protrusion on one side of the positioning rod.
[0012] This utility model has the following advantages: by setting detachable and replaceable baffles on both sides of the pulley, and then installing sliding balls on both sides of the baffles, the contact surface with the nested structure at the bottom of the sliding door is increased. In addition, the pads are used to reduce collision buffering, which can prevent the connecting plate from separating from the track wheel and improve stability. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] Please refer to the following: Figure 1-4The device shown includes a support plate 1, a nested structure connected to a connecting plate 3, and a sliding door structure. The support plate 1 is fixedly connected to the contact surface by bolts. A support frame 2 is welded to the upper end of the support plate 1. The connecting plate 3 is rotatably connected to the upper side of the support frame 2 via a rotating shaft. Both sides of the upper end of the connecting plate 3 are rotatably connected to pulleys 4. Both sides of the pulleys 4 are in contact with baffles 5. By setting baffles 5, the direct collision between the connecting plate 3 and the nested structure can be reduced, and the damage to the connecting plate 3 and the pulleys 4 can be reduced. Both sides of the baffles 5 are rotatably embedded with ball bearings 6. A positioning rod 7 is threadedly connected to one side of the connecting plate 3. A protrusion is fixedly connected to one side of the positioning rod 7. The positioning rod 7 is sleeved on the baffle 5. The baffle 5 of appropriate size is replaced according to the nested structure on the bottom side of the sliding door structure, and then the positioning rod 7 is used for connection, which also prevents the sliding door from detaching from the pulleys 4.
[0020] Among them, the cleaning brush 8 is fixedly connected to both sides of the baffle 5. The cleaning brush 8 is composed of bristles. By setting the cleaning brush 8, the nested structure on the bottom side of the sliding door can be cleaned.
[0021] Among them, the connecting plate 3 is in contact with one side of the reinforcing rib 9, and the reinforcing rib 9 is fixedly connected to one side of the baffle 5. By setting the reinforcing rib 9, the stability of the connection between the connecting plate 3 and the baffle 5 is increased.
[0022] Among them, the pad 10 is fixedly connected to the baffle 5. The pad 10 is made of rubber material. By setting the pad 10, the buffering performance of the nested structure colliding with the baffle 5 can be increased.
[0023] The positioning rod 7 is fitted with a gasket 11, which contacts one side of the baffle 5. By setting the gasket 11, the stability of the connection between the positioning rod 7 and the baffle 5 is improved.
[0024] The hidden groove 12 is provided with a protrusion, which is fixedly connected to the positioning rod 7. The hidden groove 12 is located on one side of the baffle 5. By setting the hidden groove 12, the nested structure is prevented from contacting the protrusion on one side of the positioning rod 7, thus reducing collision damage.
[0025] Working principle: Select a suitable baffle 5 and connect it with positioning rod 7. At this time, the reinforcing rib 9 contacts the connecting plate 3 and blocks both sides of the connecting plate 3. At the same time, the pad 10 corresponds to both sides of the nested structure. Then, the protrusion of the positioning rod 7 is located in the hidden groove 12, which fits the nested structure on the bottom side of the sliding door onto the upper side of the pulley 4. When the sliding door moves, it can provide effective support and avoid direct contact between the pulley 4 and the nested structure, thus improving stability and anti-detachment.
