Description

Technical Field

[0001] This utility model belongs to the field of drawer slide technology, and in particular relates to a double-position push-in steel ball drawer slide structure. Background Technology

[0002] Drawer slides, also known as drawer slides or slide rails, are hardware connection components fixed to the cabinet body of furniture, allowing drawers or cabinet panels to move in and out. Drawer slides are suitable for connecting drawers in wooden and steel furniture such as cabinets, furniture, filing cabinets, and bathroom vanities.

[0003] Chinese patent (CN201821394722.X) discloses a double-position push-in ball bearing drawer slide structure, including a first slide section, a second slide section, a third slide section, a sub-piece, and a mother piece. The first slide section, the second slide section, and the third slide section are connected sequentially by rails. The sub-piece includes an A-position, a B-position, a sub-piece elastic edge, a first mounting slot, a second mounting slot, and a concave triangle. The sub-piece is directly engaged into the groove of the first slide section through the first mounting slot and the second mounting slot. The sub-piece elastic edge is located at one end of the sub-piece. The mother piece is installed on the second slide section and has A-position and B-position points.

[0004] Currently, drawer slides use latches to release the limits between the slides, which can cause children to accidentally trigger the latches, leading to drawers falling off and injuring children, thus reducing the safety of drawer slides. Utility Model Content

[0005] The purpose of this utility model is to provide a double-position push-in steel ball drawer slide structure in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a double-position push-in ball bearing drawer slide structure, comprising:

[0007] The outer track has plugs connected to both ends, and the plugs are provided with T-shaped grooves.

[0008] The middle track is slidably connected to the outer track via ball bearing blocks;

[0009] An elastic limiting mechanism is installed on the middle track and is located between the middle track and the outer track;

[0010] The inner track is slidably connected within the middle track by ball bearing blocks.

[0011] As a further description of the above technical solution:

[0012] Multiple mounting holes are provided on both the outer and inner tracks.

[0013] As a further description of the above technical solution:

[0014] The middle track is provided with a first bending limit piece at each of its opposite ends.

[0015] As a further description of the above technical solution:

[0016] A second bending limit piece is provided at one end of the middle track and one end of the inner track.

[0017] As a further description of the above technical solution:

[0018] The elastic limiting mechanism includes a T-block, a magnetic block, and a spring. A groove is provided on the central track. The T-block is slidably connected in the groove. The magnetic block is fixedly connected to the end of the T-block. The magnetic block is connected to the bottom wall of the groove through the spring.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1. In this utility model, a three-section drawer slide structure is formed by the sliding connection of the outer track, middle track and inner track using ball blocks. The elastic limiting mechanism is triggered by magnetic action, so that the elastic limiting mechanism can smoothly pass through the T-shaped groove on the end cap, thereby limiting the drawer slide and preventing children from accidentally touching the buckle and causing the drawer to fall off, thus improving the safety factor of the drawer slide.

[0021] 2. In this utility model, the T-block and T-slot are misaligned under the elastic action of the spring. An external magnet is used to align with the slide groove of the middle track. The magnet magnetically attracts or repels the magnetic block, thereby causing the T-block to slide in the slide groove, so that the T-block aligns with the T-slot. This completes the release of the limit between the outer track and the middle track, avoiding accidental contact. This ensures that the drawer slide has a quick-release function while maintaining a high safety factor. Attached Figure Description

[0030] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6 This utility model provides a technical solution: a double-position push-in ball bearing drawer slide structure, comprising:

[0032] The outer track 1 has plugs 2 connected to both ends, and the plugs 2 have T-shaped grooves 3.

[0033] The middle track 4 is slidably connected to the outer track 1 via ball bearing blocks 5;

[0034] An elastic limiting mechanism 6 is installed on the middle track 4, and the elastic limiting mechanism 6 is located between the middle track 4 and the outer track 1;

[0035] The inner track 7 is slidably connected to the middle track 4 via ball bearing blocks 5;

[0036] Multiple mounting holes 8 are provided on both the outer track 1 and the inner track 7. The mounting holes 8 on the outer track 1 are used to fix the outer track 1 to the cabinet with screws, and the mounting holes 8 on the inner track 7 are used to fix the outer track 1 to the drawer with screws.

[0037] Both ends of the middle track 4 are provided with first bending limiting pieces 9, which are used to limit the sliding of the ball block 5 in the middle track 4.

[0038] A second bending limiting piece 10 is provided at one end of the middle track 4 and one end of the inner track 7. The second limiting piece is used to limit the mutual movement between the middle track 4 and the inner track 7.

[0039] The elastic limiting mechanism 6 includes a T-shaped block 61, a magnetic block 62, and a spring 63. A groove 11 is provided on the middle track 4. The T-shaped block 61 is slidably connected in the groove 11, and the magnetic block 62 is fixedly connected to the end of the T-shaped block 61. The magnetic block 62 is connected to the bottom wall of the groove 11 through the spring 63. The T-shaped block 61 is made of non-magnetic material. Under the elastic action of the spring 63, the T-shaped block 61 and the T-groove 3 are misaligned. An external magnet is used to align with the groove 11 of the middle track 4. The magnet magnetically attracts or repels the magnetic block 62, thereby causing the T-shaped block 61 to slide in the groove 11, so that the T-shaped block 61 is aligned with the T-groove 3. This completes the release of the limiting between the outer track 1 and the middle track 4, avoiding accidental contact and ensuring that the drawer slide has a quick-release function while maintaining a high safety factor.

[0040] Working principle: First, when assembling the drawer slides, ball bearing blocks 5 are installed inside the outer slide 1. The elastic limiting mechanism 6 is pre-installed between the middle slide 4 and the outer slide 1. Specifically, a magnetic block 62 is fixedly connected to the end of a T-block 61, one end of a spring 63 is fixed to the bottom wall of the slide groove 11, and the other end of the magnetic block 62 is fixedly connected to the other end of the spring 63. Then, the middle slide 4 is inserted into the ball bearing blocks 5. The steel balls on the ball bearing blocks 5 roll and support the outer slide 1 and the middle slide 4. Two plugs 2 are fixed to the opposite ends of the outer slide 1 with bolts. At this time, the T-block 61 and the T-slot 3 are misaligned. Then, ball bearing blocks 5 are installed inside the middle slide 4, and the inner slide 7 is inserted into the ball bearing blocks 5. The steel balls on the ball bearing blocks 5 roll and support the middle slide 4 and the inner slide 7. The end of the middle slide 4 is bent... The two first bending limit pieces 9 and the second bending limit piece 10 of the inner rail 7 are bent to complete the assembly of the drawer slide. Next, the mounting holes 8 on the outer rail 1 are used to fix the outer rail 1 to the cabinet with screws, and the mounting holes 8 on the inner rail 7 are used to fix the outer rail 1 to the drawer with screws, thus completing the assembly of the drawer and the drawer slide. Finally, when the middle rail 4 and the outer rail 1 of the drawer slide need to be released from the limit, the external magnet is aligned with the slide groove 11 of the middle rail 4. The magnet magnetically attracts or magnetically repels the magnetic block 62, thereby causing the T-shaped block 61 to slide in the slide groove 11, so that the T-shaped block 61 is aligned with the T-shaped groove 3. Pushing the middle rail 4 can complete the release of the limit between the outer rail 1 and the middle rail 4, avoiding accidental contact.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
