Description

A buffer for flat sliding doors with anti-jump wheel adjustment function

technical field

The utility model relates to a buffer for a flat sliding door, in particular to a buffer for a sliding door with the function of adjusting an anti-jumping wheel.

Background technique

At present, the buffer damper is generally used on the flat sliding door of the furniture, and the shift block of the toggle damper installed in the upper track of the flat sliding door, when the flat sliding door is pushed to the side, the shift block is stuck in the damper. On the movable part, the sliding door is driven to move slowly until it stops beside the frame of the door. Due to the buffering effect of the damper, the sliding door will not collide when it is close to the door frame, avoiding noise due to collision, and even protecting the flat sliding door. The sliding door will not be damaged by collision, so it is very popular among consumers. However, when people push the sliding door with excessive force or force, due to the large inertia of the sliding door at this time, the moment when the shifting block cooperates with the damper, the phenomenon of bouncing will appear on one side of the sliding door. Noise is generated, and when it is serious, the bottom wheel of the flat sliding door is easy to break away from the track.

In order to solve the above drawbacks, there is an urgent need to propose a buffer for flat sliding doors with an anti-jumping wheel adjustment function.

Utility model content

The purpose of this utility model is achieved in the following ways: a flat sliding door buffer with anti-jump wheel adjustment function, which includes a fixed main board, a sliding wheel installed on the top of the fixed main board and connected to the door body on one side of the fixed main board The foot fork is characterized in that: the above fixed main board is provided with an anti-jumping wheel group, and the described anti-jumping wheel group includes a movable plate hinged with the fixed main board and an anti-jumping wheel located on one side of the movable plate, and the movable plate The transmission plate is connected with the adjustment screw, and the transmission plate is pushed forward and backward by rotating the adjustment screw, so that the movable plate swings, thereby changing the relative distance between the anti-jumping wheel and the fixed main board.

The movable plate is respectively riveted with the anti-jumping wheel, the fixed main plate and the transmission plate through fixed rivets.

The transmission plate includes a lateral side plate and a vertical side plate, which are distributed in the shape of ""; the lateral side plate is riveted with the movable plate, and the vertical side plate is adjusted through the threaded hole on it. Screw on.

The fixed main board is also riveted with a positioning column, and the adjustment screw passes through the positioning column and is screwed to the transmission plate.

The cylinder surface of the adjustment screw is provided with a slot, the adjustment screw is installed in the through hole on the positioning column, and the circlip is placed on the slot of the adjustment screw to limit the axial movement of the adjustment screw and the positioning column .

The beneficial effects of the utility model are: 1) The structure is simple, the production cost is low, and the market competitiveness is improved. 2) The anti-jumping wheel set is installed on the buffer, and the anti-jumping wheel in the anti-jumping wheel set is used to push against the guide rail to limit the gap for the upward movement of the door body and play the role of anti-jumping. 3) It is convenient to adjust the working state of the anti-jumping wheel, which is beneficial to make the anti-jumping wheel achieve the best working effect, prevent the anti-jumping wheel from being too loose to play the anti-jumping effect, and also avoid the resistance of the door body switch if the anti-jumping wheel is too tight Large, short service life and other disadvantages.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is specifically further described. A flat sliding door buffer with anti-jump wheel adjustment function, which includes a fixed main board 1, a sliding wheel 2 installed above the fixed main board 1, and a foot fork 3 connected to the door body 4 on one side of the fixed main board 1. It is characterized in that an anti-jumping wheel set 5 is provided above the fixed main board 1, and the anti-jumping wheel set 5 includes a movable plate 51 hinged with the fixed main board 1 and an anti-jumping wheel 52 arranged on one side of the movable plate 51, The movable plate 51 is connected with the adjusting screw 7 through the transmission plate 6, and the driving plate 6 is moved forward and backward by rotating the adjusting screw 7, so that the movable plate 51 swings, thereby changing the relative distance between the anti-jumping wheel 52 and the fixed main board 1 .

The movable plate 51 is riveted with the anti-jumping wheel 52, the fixed main plate 1 and the transmission plate 6 respectively through the fixed rivets 8.

The transmission plate 6 includes a lateral side plate 61 and a longitudinal side plate 62, and the lateral side plate 61 and the longitudinal side plate 62 are distributed in a “7” shape; the lateral side plate 61 is riveted with the movable plate 51, and the 62 is screwed with the adjusting screw 7 through the threaded hole 9 thereon.

The fixed main board 1 is also riveted with a positioning column 10, and the adjusting screw 7 passes through the positioning column 10 and is screwed with the transmission plate 6.

The cylindrical surface of the adjusting screw 7 is provided with a draw-in groove 11. After the adjusting screw 7 is installed in the through hole 12 arranged on the positioning column 10, the jumper 13 is stuck on the draw-in groove 11 of the adjusting screw 7 to limit the adjustment. The axial movement of the screw 7 and the positioning column 10.

Working principle: When installing, after the buffer is connected to the door body through the fixed main board, the door body is put into the guide rail. Since there is a certain gap between the top of the door body and the bottom end of the guide rail 14, the door body has room for upward movement. As a result, the lower end of the door body is easily separated from the guide rail. In the utility model, the anti-jumping wheel group is installed on the buffer, and the anti-jumping wheel in the anti-jumping wheel group is used to push in the guide rail to limit the upward movable gap of the door body and play the role of anti-jumping.

When the door body is installed in the guide rail 14, by rotating the adjusting screw, the drive plate is pushed forward or backward, so that the movable plate rotates around its own fixed rivet, so that the anti-jump wheel is lifted upwards and contacts with the groove bottom of the guide rail. , to fill the gap between the door body and the bottom of the guide rail groove.

Since the anti-jumping wheel set adjusts the relative distance between the anti-jumping wheel and the fixed main board, and is adjusted in the guide rail used for its work, it can update the working state of the anti-jumping wheel in time, which is conducive to making the anti-jumping wheel To achieve the best working effect, prevent the anti-jumping wheel from being too loose to prevent the anti-jumping effect, and the anti-jumping wheel from being too tight, the door body switch resistance is large, and the service life is short.

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model The new model also has various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model.
