Buffer mechanism of slide return device

The present invention is a buffer mechanism for a slide return device, and particularly can greatly simplify the structural complexity of the buffer mechanism and speed up assembly, thereby achieving the effects of simplified structure, rapid assembly, and reduced cost.

The buffer mechanism generally used for the slide rail mechanism or the slide return device can be roughly classified into a hydraulic type or a pneumatic type according to the source of the internal cushioning resistance, that is, a fluid such as a liquid (ie, hydraulic type) or a gas (ie, Pneumatic type) to provide the effect of cushioning damping. In addition to the complicated structure, such conventional buffer rods are prone to oil leakage or air leakage, which leads to inconvenience in maintenance and cleaning.

In view of the above-mentioned shortcomings, the industry has also changed the way to make the rubber damping and the inner side wall surface of a hollow pipe body to provide the required cushioning force. For example, the Republic of China Patent Gazette No. M377463 "conveniently assembled buffer bar structure" Please refer to the first figure, which is composed of a hollow tube body 11, a shaft center 12, a mounting shaft 14 and a damping unit 13, wherein the shaft center 12 is movably mounted in the hollow body. The inside of the tube body 11 and the top end thereof are exposed to the hollow tube body, the front end of the mounting shaft 14 is mounted on the bottom end of the shaft core 12, and the damping unit 13 is composed of a cushioning material such as rubber or foam material. The front end of the damper unit 13 is sleeved on the front end of the mounting shaft 14. The damper unit 13 has a protruding sliding portion 131 at the rear end thereof, and the shaft center 12 is usually attached to the external sliding rail mechanism or the sliding rail return device. The connection is made so that the axis 12 can be interlocked with the slide rail mechanism or the slide return device, and the positioning of the slide rail is as claimed in the Republic of China Patent Application No. 100216920 filed by the creator of the present application. Regression device (2), which revealed a slip return The embodiment in which the device is combined with a conventional buffer rod can be buffered to reduce collision or noise when the slide return device is returned; the principle of the buffering effect of the "conveniently assembled buffer rod structure" is to utilize the axis 12 can slide outward relative to the hollow tube 11 as the rail device is opened, and when the rail device is folded, the shaft 12 slides inward relative to the hollow tube 11, and the shaft 12 The sliding portion 131 of the damper unit 13 rubs against the inner wall surface of the hollow tube body 11. The damper unit 13 is slightly compressed and deformed by the sliding portion 131 to be slightly expanded in the radial direction, so that the damper unit is slightly expanded. 13 can abut against the inner tube wall of the hollow tube body 11, and can generate and provide a buffering force, so that the rail device can achieve the buffering effect during the return, thereby making the "convenient assembly buffer rod structure" Can achieve the purpose of providing buffering effect.

The "conveniently assembled buffer rod structure" can achieve the purpose of providing a buffering effect, but it must be composed of a plurality of structures such as a hollow tube body 11, a shaft core 12, a mounting shaft 14, and a damping unit 13, and must be combined. The outer diameter of the sliding portion 131 of the damper unit 13 is controlled to be slightly larger than the inner diameter of the hollow tubular body 11 to generate a frictional effect in the action to achieve a buffering effect, so that the overall structure is very complicated, and the precision of the mold is made. The requirements are relatively high. If the mold manufacturing error is large, the product may be unsatisfactory or the ideal buffering effect may be achieved, which may result in assembly time, high process cost and low product reliability, so it is necessary to improve.

Therefore, how to eliminate the above-mentioned defects is the technical difficulty point that the creators of this case want to solve.

In view of the existing buffer mechanism for the slide return device, the purpose of the present invention is to provide a buffer mechanism for the slide return device, because of its complicated structure, time-consuming assembly, high process cost, and low product reliability. The buffer mechanism directly rubs against the slide return device to achieve a buffering effect, and the actuating mechanism of the buffer mechanism is integrated with the returning reset action of the slide return device, so the slide return device only needs to be increased in structure. The arrangement of the pressing portion can greatly simplify the structural complexity of the buffer mechanism and speed up the assembly speed, thereby enabling the creation to achieve the advantages of simplified structure, quick assembly and low cost.

In order to achieve the above object, the present invention provides a buffer mechanism for a slide return device, comprising: a slide return device, the slide return device is provided with a fixed seat, a sliding mechanism and a paddle, and the sliding mechanism is slidable The sliding mechanism further comprises a release claw, the release claw further comprising a pressing portion on the side of the release claw, the paddle overlapping the groove of the fixing seat; a buffer mechanism The buffer mechanism is sleeved with the sliding mechanism, and the buffer mechanism is slidably disposed on one side of the inner side wall of the accommodating space, and the buffer mechanism is located between the pressing portion and the inner side wall of the releasing claw The buffering effect is achieved by using the buffer mechanism to directly rub against the slide return device, and the actuating mechanism of the buffer mechanism is integrated with the returning reset action of the slide return device, and thus the slide return device The structure only needs to increase the setting of a pressing portion, which can greatly simplify the structural complexity of the buffer mechanism and speed up the assembly speed, thereby simplifying the structure of the creation. Assembly is quick and cost-effectiveness of reducing.
