Description

Technical Field

[0001] This utility model relates to the field of reciprocating guide rail technology, and in particular to a silent reciprocating sliding device. Background Technology

[0002] Reciprocating sliding devices are widely used in mechanical transmission, furniture manufacturing, and precision equipment, such as in functional furniture; while traditional structures mostly use the form of direct contact between guide rails and sliders to achieve guidance and movement.

[0003] However, most existing guide rail sliders generate mechanical noise due to the rigid contact between their metal components. In noise-sensitive environments such as medical operating rooms and high-end smart homes, traditional structures cannot meet the requirements for quiet operation. Furthermore, existing sound insulation measures (such as rubber damping pads and lubricants) can only reduce noise to a limited extent, and their effectiveness is easily diminished after long-term use. In addition, the sliding friction of direct contact can cause rapid wear of components. Under high-frequency use, the gap between the slider and the guide rail increases, leading to a decrease in motion accuracy or even jamming, and affecting the stability of its use, resulting in poor practicality. Utility Model Content

[0004] In view of the fact that the existing traditional reciprocating sliding device has high noise, fast wear and easy deterioration of motion accuracy due to the rigid metal contact between the guide rail and the slider, it is difficult to meet the requirements of quiet and high reliability scenarios, so this utility model is proposed.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a silent reciprocating sliding device, including a guide rail, both ends of which can be detachably installed with end caps, and a reciprocating sliding mechanism is slidably installed in the guide rail;

[0006] The reciprocating sliding mechanism includes a sliding component and a positioning component. The sliding component includes a connecting plate, which is disposed above the guide rail. A mounting plate is fixedly connected to the bottom of the connecting plate. Mounting holes are symmetrically opened on one side of the mounting plate. Mounting shafts are rotatably installed in the mounting holes. Rollers are respectively connected to both ends of the mounting shafts on the outside of the mounting plate.

[0007] As a preferred embodiment, the positioning component includes four mounting blocks, which are evenly distributed on both sides of the mounting plate, with two mounting blocks on the same side being symmetrically arranged. A limiting groove is formed on the side of the mounting block away from the mounting plate, and a ball bearing is movably installed in the limiting groove. The ball bearing contacts the inner wall and top wall of the guide rail.

[0008] As a preferred embodiment, the two mounting blocks on the same side are integrally formed, and each of the two mounting blocks has a mounting groove at one of its inner ends. A pre-installed hole is opened on one side of the mounting plate, and the pre-installed hole is located between the two mounting grooves. The mounting grooves are adapted to the rollers, and both the ball bearings and the rollers are made of soft material.

[0009] As a preferred embodiment, the mounting block has an arc groove at its bottom end near the mounting shaft that is adapted to the roller, and the mounting block is fixedly connected to the mounting plate.

[0010] As a preferred embodiment, the connection between the mounting plate and the connecting plate, and the connection between the mounting block and the mounting plate, are all chamfered.

[0011] As a preferred embodiment, the connecting plate has symmetrical connecting holes on its top, and the connecting plate and the mounting plate are combined in a T-shape, with the connecting plate and the mounting plate not in contact with the guide rail.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] 1. This utility model can prevent the connecting plate and mounting plate in the reciprocating sliding mechanism from contacting the guide rail, thereby avoiding metal-to-metal friction between them, generating noise, reducing wear, and improving service life.

[0014] 2. This utility model uses positioning components to support and limit the connecting plate and mounting plate, preventing them from contacting the guide rail while ensuring greater stability and thus making them more stable.

[0015] 3. The rollers and balls of this utility model are made of soft materials, which further reduces noise.

[0016] 4. The pre-installed holes and mounting grooves in this utility model are designed so that when the load is large, a set of rollers can be added to improve its load-bearing and support capacity. Attached Figure Description

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Reference Figures 1-4 As shown, a silent reciprocating sliding device is provided, including a guide rail 1. End caps 2 can be detachably installed at both ends of the guide rail 1. A reciprocating sliding mechanism 3 is slidably installed inside the guide rail 1. The reciprocating sliding mechanism 3 includes a sliding component 4 and a positioning component 5. The sliding component 4 includes a connecting plate 6, which is disposed above the guide rail 1. A mounting plate 7 is fixedly connected to the bottom of the connecting plate 6. Mounting holes 10 are symmetrically opened on one side of the mounting plate 7. Mounting shafts 8 are rotatably installed in the mounting holes 10. Rollers 9 are respectively connected to the two ends of the mounting shafts 8 on the outside of the mounting plate 7. The rolling friction of the rollers 9 replaces the sliding friction between the traditional slider and the guide rail 1, reducing noise and wear caused by direct metal contact and improving service life. In this example, the positioning component 5 includes four mounting blocks 12, which are evenly distributed on both sides of the mounting plate 7. Two mounting blocks 12 on the same side are symmetrically arranged. A limiting groove 14 is formed on the side of the mounting block 12 away from the mounting plate 7. A ball bearing 15 is movably installed in the limiting groove 14. The ball bearing 15 contacts the inner wall and top wall of the guide rail 1. The rolling contact between the ball bearing 15 and the inner wall of the guide rail 1 is used to achieve support and limiting, avoiding direct contact between the connecting plate 6, the mounting plate 7 and the guide rail 1. At the same time, the sliding stability is improved through multi-point support.

[0025] In this example, the two mounting blocks 12 on the same side are integrally formed. Each of the two mounting blocks 12 has a mounting groove 13 on one of their inner sides. A pre-installed hole 11 is opened on one side of the mounting plate 7, and the pre-installed hole 11 is located between the two mounting grooves 13. The mounting groove 13 is adapted to the roller 9. Both the ball bearing 15 and the roller 9 are made of soft material. The soft material of the ball bearing 15 and the roller 9 can further absorb vibration and reduce noise. At the same time, the combination design of the pre-installed hole 11 and the mounting groove 13 provides an interface for expanding the number of rollers 9, which makes it easy to flexibly enhance the support according to the load requirements.

[0026] In this example, the bottom of the mounting block 12 near the mounting shaft 8 has an arc groove that matches the roller 9. The mounting block 12 is fixedly connected to the mounting plate 7. The matching design of the arc groove and the roller 9 can optimize the rolling trajectory, reduce motion resistance, and enhance the structural synergy between the mounting block 12 and the roller 9, thereby improving the smoothness of sliding.

[0027] In this example, the connection between the mounting plate 7 and the connecting plate 6, and the connection between the mounting block 12 and the mounting plate 7 are both chamfered. Chamfering can reduce stress concentration at the connection, improve the fatigue strength of the structure, reduce the risk of interference during assembly, and facilitate quick installation and positioning.

[0028] In this example, the top of the connecting plate 6 is symmetrically provided with connecting holes 16. The connecting plate 6 and the mounting plate 7 are combined in a T-shape, and the connecting plate 6 and the mounting plate 7 do not contact the guide rail 1. The T-shaped structure ensures load-bearing capacity while eliminating metal friction noise through non-contact design. The connecting holes 16 facilitate quick assembly with external components, improving device compatibility.

[0029] The working principle of this utility model is as follows: When the reciprocating sliding mechanism 3 moves, the roller 9 at the bottom of the mounting plate 7 rotates within the guide rail 1 via the mounting shaft 8, replacing traditional sliding friction with rolling friction, thus avoiding direct contact between the connecting plate 6, the mounting plate 7, and the guide rail 1, reducing noise and wear; at the same time, the ball 15 in the upper limit groove 14 of the mounting block 12 contacts the inner side wall and top wall of the guide rail 1, achieving positioning and limiting of the sliding component 4 through rolling support, ensuring motion stability; the soft material roller 9 and ball 15 can further absorb vibration and reduce noise; the design of the pre-installed hole 11 and the mounting groove 13 allows for the addition of roller 9 according to load requirements, improving load-bearing capacity; the chamfering treatment optimizes the structural transition, reduces stress concentration, and improves assembly convenience. This device can prevent the reciprocating sliding mechanism 3 from contacting the guide rail 1, thus preventing noise caused by sliding friction between metals, and the setting of the positioning component 5 can support, limit, and guide the sliding component 4, improving its stability and making it more practical.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
