When the drawer is opened and closed, the slide rail member 200 slides relative to the track base 100, and a buffer mechanism 300 can be provided at the inner end 110 of the track base 100, so that when the drawer is closed, the slide rail member 200 can be connected with the buffer mechanism 300, and the buffer mechanism 300 can buffer the sliding movement between the slide rail member 200 and the track base 100, so that the drawer can be buffered when it is closed, so that the drawer will not impact the tool cabinet body, and can reduce Less noise, reduced impact damage, and when the buffer track is assembled, the insertion structure 400 on the buffer mechanism 300 can enable the buffer mechanism 300 to be inserted into the opening of the inner end 110 of the track base 100. Since the opening at the end of the track base 100 is larger, there is no need for precise alignment during insertion, and it can be quickly inserted into the track base 100. The track base 100 and the buffer mechanism 300 are provided with a clamping structure 500. When the buffer mechanism 300 is inserted, the clamping structure 500 can be clamped at a predetermined position, so that the buffer mechanism 300 can be assembled while being inserted and clamped, which can make the assembly process more convenient, thereby improving the assembly efficiency of the buffer mechanism 300.

[0034] Reference Figures 1 to 5 In some embodiments of the present invention, the insertion structure 400 includes a stopper 410 and an insertion part 420, the clamping structure 500 includes at least one clamping member 510 and a clamping slot 520 of the same number as the clamping member 510, the clamping slot 520 is provided on the track base 100, the clamping member 510 is provided on the buffer mechanism 300, the clamping member 510 can be clamped with the corresponding clamping slot 520 to limit the buffer mechanism 300 from moving toward the inner end 110, the stopper 410 is provided at the end of the insertion part 420, the insertion part 420 can be slidably matched with the track base 100, and the stopper 410 can abut against the inner end 110 of the track base 100 to limit the buffer mechanism 300 from moving toward the outer end 120. The above structures cooperate together to realize the positioning and assembly of the buffer mechanism 300, and the assembly process is more convenient and fast.

[0035] Specifically, the plug-in structure 400 is arranged on the buffer mechanism 300, the plug-in portion can be set to match the shape of the track base 100, and is arranged on both sides of the buffer mechanism 300, the stopper 410 is arranged at the end of the plug-in portion, and the stopper 410 can be set larger than the end of the track base 100, so that the inner side wall of the stopper 410 can abut against the end of the track base 100, the clamping structure 500 can be set as a clamping member 510 and a clamping groove 520, the clamping groove 520 can be set on the track base 100, and the clamping member 510 can be set on the buffer mechanism 300. It can be understood that the clamping member 510 can be set as a triangular buckle position with an inclined surface, and the setting direction of the inclined surface matches the direction of insertion. The structure 300 can be inserted into the track base 100 through the plug-in portion, and the inclined surface of the latch 510 abuts against the track base 100 and deforms. When the latch 510 slides to the position of the slot 520, the latch 510 can be inserted into the slot 520. At this time, the stopper 410 also abuts against the end of the track base 100.

[0036] It should be noted that the snap-fit ​​structure 500 is not limited to the above embodiment, and other embodiments may also be adopted. For example, the buckle may be provided on the track base 100, and the slot 520 may be provided on the buffer mechanism 300, so as to achieve snap-fit.

[0037] Reference Figure 1 and Figure 5 In some embodiments of the present invention, the number of the buckle members 510 is three, and the three buckle members 510 are arranged in a triangle, which can improve the connection strength to meet the heavy load requirements.

[0038] Specifically, reinforced buffer slide rails are generally used on heavy-loaded cabinets, especially tool cabinets. Since many heavy tools are placed inside, the tool cabinet drawers need to be equipped with reinforced buffer devices when in use. Therefore, three snap members 510 can be provided to increase the clamping strength of the buffer mechanism 300 to increase the load-bearing weight, and the three snap members 510 can be arranged in a triangle, so that the snap members 510 and the track base 100 can be supported by two adjacent snap members 510 in the horizontal and vertical directions, which can maximize the impact resistance of the buffer mechanism 300.

[0039] It should be noted that the fastener 510 is not limited to the above embodiment, and other embodiments may also be adopted. For example, four or more fasteners 510 may be provided, and the fasteners 510 may be arranged in a square shape.

[0040] Reference Figures 2 to 4 In some embodiments of the present utility model, the buffer mechanism 300 includes a limiting slide member 310, a buffer slider 321 and a buffer damping assembly 330. The limiting slide member 310 is arranged on the track base 100, the buckle 510 is arranged on the limiting slide member 310, the buffer slider 321 is slidably connected to the limiting slide member 310, one end of the buffer damping assembly 330 is fixedly connected to the limiting slide member 310, and the other end is connected to the buffer slider 321. There is a The limiting structure, the buffer slider 321 has a first position. In the first position, the buffer slider 321 can be clamped in the limiting slide groove member 310 through the limiting structure, and the buffer damping assembly 330 can be stretched to form a buffer stroke. The slide rail member 200 has a second position. In the second position, the slide rail member 200 can cooperate with the buffer slider 321 and drive the buffer slider 321 to disengage from the limiting structure, so that the buffer slider 321 can buffer the relative movement between the slide rail member 200 and the track base 100.

[0041] Specifically, the limiting slide groove member 310 is located in the track base 100, and the buffer slider 321 is slidably connected to the limiting slide groove member 310, so that the buffer slider 321 can slide within the slide groove range of the limiting slide groove member 310, and the buffer damping component 330 is the main buffer component. The specific buffer structure is not specifically limited. One end of the buffer damping component 330 is fixedly connected to the limiting slide groove member 310, and the other end is connected to the buffer slider 321. The buffer damping component 330 can be stretched and compressed as the buffer slider 321 slides. The limiting structure between the limiting slide member 310 and the buffer slider 321 can make the buffer slider 321 clamped in the first position of the limiting slide member 310. In the first position, the buffer damping component 330 can be stretched to form a buffer stroke. In specific use, when the drawer is closed, the drawer is pushed toward the inner end 110, and the slide rail member 200 slides toward the inner end 110. At this time, the buffer slider 321 is in the first position. When the slide rail member 200 slides toward the inner end 110 to the second position, the slide rail member 200 cooperates with the buffer slider 321 located at the first position to connect. Then, at this time, the buffer slider 321 can be separated from the limiting structure under the action of the slide rail member 200, so that the buffer slider 321 can move, and the slide rail member 200 acts on the buffer stroke of the buffer slider 321 at this time, so that the slide rail member 200 can buffer the relative movement with the track base 100 under the buffering action provided by the buffer damping assembly 330, thereby achieving a buffering effect. When the drawer is opened, the slide rail member 200 slides toward the outer end 120, thereby driving the buffer slider 321 to slide toward the outer end 120. When the buffer slider 321 moves When sliding outward, the buffer damping assembly 330 is stretched again to form a buffer stroke. When the slide rail 200 slides to the second position, the buffer slider 321 slides to the first position at the same time. At this time, the buffer slider 321 is engaged with the limiting structure, and the slide rail 200 is disconnected from the buffer slider 321. The limiting structure can keep the buffer slider 321 fixed to maintain the buffer stroke. Through the mutual cooperation of the limiting structure, the buffer slider 321 and the slide rail 200, when used in a drawer, it can be pulled and reciprocated to achieve a circulating effect.

[0042] Reference Figure 3 to Figure 4 In some embodiments of the present invention, the buffer damping assembly 330 includes an elastic member 331 and a damper 332. One end of the elastic member 331 is connected to the buffer slider 321, and the other end is connected to the limiting slide member 310. One end of the damper 332 is connected to the buffer slider 321, and the other end is connected to the limiting slide member 310. Through the above structure, the buffering effect can be achieved, and the drawer can be automatically closed in place.

[0043] Specifically, the elastic member 331 can be a spring, the damper 332 can be a buffer cylinder, the buffer slider 321 can be fixedly connected to one end of the spring and to the movable rod of the buffer cylinder of the damper 332, and the other end of the elastic member 331 and the damper 332 are connected to the limiting slide rail member 200. When the buffer slider 321 slides, the elastic member 331 and the damper 332 can be stretched, and the damper 332 can form a buffer stroke after stretching, and the spring can form a certain elastic force after stretching. When the drawer is closed, the elastic force can provide the slide rail member 200 to slide toward the inner end 110, so that the user can close the drawer in place without applying external force, and the elastic force interacts with the damper 332 to slow down the movement speed of the slide rail member 200, thereby achieving a buffering effect.

[0044] It should be noted that the buffer damping assembly 330 is not limited to the above-mentioned embodiments, and other embodiments may also be adopted. For example, the buffer damping assembly 330 may only have a damper 332, or may have two elastic members 331 and one damper 332, and the two elastic members 331 may be arranged on both sides, and the damper 332 may be arranged in the middle.

The limiting structure can be realized without setting multiple components, and the structure is simple.

[0046] The first and second slide grooves 312 and 313 are preferably arranged in a staggered manner, and the length directions of the first and second slide grooves 312 and 313 are parallel to the length direction of the rail base 100. The transverse slide groove 314 connects the first and second slide grooves 312 and 313 so that the overall slide groove forms a Z shape. A movable sliding column 3211 can be arranged on the buffer slider 321. The sliding column 3211 can move laterally relative to the buffer slider 321 to match the staggered position of the first and second slide grooves 312 and the second slide grooves 313. When the buffer slider 321 is assembled, the sliding column 3211 can be installed with the open end of the second slide groove 313 to achieve sliding cooperation, which can facilitate assembly. After the sliding column 3211 slides through the transverse slide groove 314 and reaches the first slide groove 312, the sliding column 3211 can slide on the first slide groove 312 and drive the buffer damping assembly 330 to stretch. When the sliding column 3211 slides to When the slide rail 200 is pushed toward the inner end 110 and closed, the sliding post 3211 is still at the upper limit position of the horizontal slide groove 314, and the slide rail 200 is pushed toward the inner end 110 and closed. When the member 200 is connected to the sliding column 3211, the sliding column 3211 is driven to slide from the transverse sliding groove 314 to the first sliding groove 312 to fall off the limit, and when the slide rail member 200 is pulled toward the outer end 120 to open, the sliding column 3211 is clamped into the transverse sliding groove 314 by the slide rail member 200 from the first sliding groove 312, and the slide rail member 200 is disconnected from the sliding column 3211, and the limiting structure is realized through the cooperation between the sliding column 3211 and the transverse sliding groove 314.

[0047] It should be noted that the limiting sliding groove member 310 is not limited to the above-mentioned embodiment, and other embodiments may also be adopted. For example, only the first sliding groove 312 and the transverse sliding groove 314 may be provided to form an L-shaped sliding groove.

The inner wall of the guide groove 211 is provided with a clamping portion 212, and the clamping portion 212 is triangular in shape. The clamping portion 212 can guide the sliding column 3211 to be clamped into or out of the horizontal slide groove 314. The guide member 210 has a simple structure and is easy to assemble.

[0049] Specifically, the end of the guide member 210 can be provided with a guide groove 211 inwardly, and the clamping portion 212 can cooperate with the guide groove 211 to form a C-shaped groove body. In the specific use process, the sliding column 3211 needs to move between the first slide groove 312 and the transverse slide groove 314, so that the sliding column 3211 needs to move up and down, and the guide member 210 can guide the sliding column 3211 to move up and down. When the slide rail member 200 is closed toward the inner end 110, the buffer slider 321 is in the first position, and the guide groove 2 11 cooperates with the sliding column 3211, and the guide groove 211 guides the sliding column 3211 to move toward the bottom of the clamping block, so that the sliding column 3211 can be separated from the horizontal sliding groove 314. At the same time, the clamping block can be clamped with the sliding column 3211, so that the sliding column 3211 can drive the guide member 210 to move. When the slide rail member 200 is pulled out, the sliding column 3211 can cooperate with the horizontal sliding groove 314, and the horizontal sliding groove 314 can guide the sliding column 3211 to fall off the clamping block to achieve the above-mentioned clutch function.

The first connecting part 3212B and the second connecting part 3212C can be connected to the ends of the elastic member 331 and the damper 332 by snap-fitting, or connected by fasteners, and the specific connection direction is not specifically limited.

[0052] It should be noted that the positions of the first connection portion 3212B and the second connection portion 3212C are not limited to the above embodiment, and other embodiments may also be adopted. For example, the first connection portion 3212B and the second connection portion 3212C may be arranged in the middle of the buffer slider 321 .

[0053] Reference Figures 2 to 4In some embodiments of the present invention, the side wall of the first slide groove 312 is provided with an elastic portion 3121, and the elastic portion 3121 is arranged near one end of the inner end 110. Specifically, a hollow portion can be arranged on one side of the first slide groove 312 near the inner end 110, so that the side wall of the first slide groove 312 can be deformed toward the outer shape, thereby widening the width of the first slide groove 312. When used for the first time, the sliding column 3211 is located in the first slide groove 312, and the guide member 210 needs to cooperate with the sliding column 3211 to pull out the buffer slider 321, and the elastic portion 3121 can enable the sliding column 3211 to move in the width direction of the first slide groove 312, so that the sliding column 3211 can bypass the clamping portion 212 and enter the guide groove 211, and the clamping portion 212 can also drive the sliding column 3211 to slide outward.
