Description

Technical Field

[0001] This utility model relates to the field of slide rails, and in particular to a slide rail with a roller controller. Background Technology

[0002] Existing standard slide rails have limited functionality. Taking a three-section slide rail as an example, it is only used for reciprocating linear motion, serving to save space through extension and retraction. Its main drawbacks are evident in the following specific scenarios: for example, when the slide rail tilts forward, the middle and inner rails may slide out uncontrollably under gravity; when the slide rail tilts backward, the middle and inner rails may retract uncontrollably under gravity; and when the slide rail extends at excessive speed, the inner and middle rails may spring back under the reaction force. These abnormal situations can easily cause wear and tear on the mechanism and damage to the track's load-bearing components. Because existing slide rails lack control components, they cannot simultaneously meet the functional requirements of closed retention and pull-out locking. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a slide rail with a roller controller, which locks by rollers and prevents return by movable rod, effectively dealing with the problem of slide rail uncontrolled unfolding or automatic sliding back in working scenarios, improving the reliability of action and improving sliding efficiency.

[0004] To solve the above-mentioned technical problems, the present invention provides a sliding rail with a roller controller, comprising an inner rail, a middle rail, an outer rail, steel balls, a positioning steel plate, a movable rod, and rollers. The inner rail, middle rail, and outer rail are nested from the inside out. The gap walls of the inner rail, middle rail, and outer rail are all provided with raceways. The steel balls are arranged in rows and filled in the raceways. A slot is opened at the rear end of the top wall of the outer rail. A positioning steel plate is externally connected to the rear end of the side wall of the inner rail. The movable rod is installed on the positioning steel plate by screws. A roller is installed at the end of the movable rod through a rotating shaft. A spring is engaged at the top of the movable rod. The spring pushes upward against the positioning steel plate and locks the roller on the movable rod into the slot.

[0005] In a preferred embodiment of this utility model, the inner rail, middle rail, and outer rail are all equipped with steel ball limiting blocks that block the raceway at their rear ends by screws.

[0006] In a preferred embodiment of this utility model, the inner rail and the middle rail are aligned with the front end of the outer rail.

[0007] In a preferred embodiment of this utility model, the front ends of both the outer rail and the middle rail are equipped with limiting rivets, and the limiting rivets are matched one-to-one with the ends of the raceway.

[0008] In a preferred embodiment of this utility model, the heights of the inner rail, middle rail, and outer rail decrease progressively. When the middle rail is unfolded, it forms a step with the outer rail. The movable rod is a long wedge-shaped block, which is pressed against the step by the elastic force of a spring.

[0009] In a preferred embodiment of this utility model, the arrangement length of the steel balls does not exceed one-half the length of the inner rail.

[0010] In a preferred embodiment of this utility model, the slot is arc-shaped and its shape and size match the roller.

[0011] In a preferred embodiment of this utility model, the positioning steel sheet has an inverted L-shaped structure and extends upward to directly above the top wall of the outer rail.

[0012] In a preferred embodiment of this utility model, the spring is V-shaped, and the top wall of the movable rod is provided with a groove for accommodating the spring, the groove being parallel to the outer rail.

[0013] In a preferred embodiment of this utility model, the movable rod is divided into a control rod and an unlocking lever by the pivot. The control rod is used to press against the outer rail to prevent return and to press the roller to close and retain.

[0014] The beneficial effects of this utility model are: the slide rail with roller controller provided by this utility model can be locked by roller and prevented from sliding back by movable rod, which can effectively deal with the problem of slide rail uncontrolled unfolding or automatic sliding back in the working scene, improve the reliability of action and improve sliding efficiency.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1-4 As shown, the embodiments of this utility model include:

[0022] A slide rail with a roller controller includes an inner rail 1, a middle rail 2, an outer rail 3, steel balls 4, a positioning steel plate 5, a movable rod 6, and rollers 7. The inner rail 1, middle rail 2, and outer rail 3 are nested from the inside out. The gap walls of the inner rail 1, middle rail 2, and outer rail 3 are all provided with raceways. The steel balls 4 are arranged in rows and filled in the raceways. The rear end of the top wall of the outer rail 3 has a slot 8. The rear end of the side wall of the inner rail 1 is externally connected to the positioning steel plate 5. The movable rod 6 is installed on the positioning steel plate 5 by screws 9. The end of the movable rod 6 is connected to the roller 7 by a rotating shaft 10. The top of the movable rod 6 is engaged with a spring 11. The spring 11 pushes upward against the positioning steel plate 5 and locks the roller 7 on the movable rod 6 into the slot 8.

[0023] Among them, the inner rail 1, middle rail 2 and outer rail 3 are all equipped with steel ball limiting blocks 12 that block the raceway at the rear end by screws 9.

[0024] Furthermore, the inner rail 1 and the middle rail 2 are aligned with the front end of the outer rail 3.

[0025] Furthermore, the front ends of both the outer rail 3 and the middle rail 2 are equipped with limiting rivets 13, which are matched one-to-one with the ends of the raceway.

[0026] Furthermore, the heights of the inner rail 1, middle rail 2, and outer rail 3 decrease progressively. When the middle rail 2 is unfolded, it forms a step with the outer rail 3. The movable rod 6 is a long wedge-shaped block, which is pressed against the step by the elastic force of the spring 11.

[0027] Furthermore, the length of the steel balls 4 arranged does not exceed one-half the length of the inner rail 1.

[0028] Furthermore, the slot 8 is arc-shaped and its shape and size match the roller 7.

[0029] Furthermore, the positioning steel plate 5 has an inverted L-shaped structure, and the positioning steel plate 5 extends upward to the top wall of the outer rail 3.

[0030] Furthermore, the spring 11 is V-shaped, and the top wall of the movable rod 6 is provided with a groove to accommodate the spring 11, the groove being parallel to the outer rail 3.

[0031] Furthermore, the movable rod 6 is divided into a control rod and an unlocking lever with the rotating shaft 10 as the boundary. The control rod is used to press against the outer rail 3 to prevent backflow and to press the roller 7 to close and retain it.

[0032] The assembly steps of this product include the following process: Roller 7 is fixed to movable rod 6 via rotating shaft 10; spring 11 is fixed between movable rod 6 and positioning steel plate 5; movable rod 6 is connected to positioning steel plate 5 via screw 9; positioning steel plate 5 is connected to inner rail 1 via screw 9; steel ball limiting block 12 is fixed to inner rail 1 and middle rail 2 respectively via screw 9; inner rail 1 and steel ball 4 are fixed to middle rail 2 via limiting rivet 13; middle rail 2 and steel ball 4 are fixed to outer rail 3 via limiting rivet 13; limiting block is fixed to outer rail 3 via screw 9.

[0033] The method of using this product is as follows: When the slide rail is fully closed, the automatic cooperation between the roller 7 and the slot 8 can keep it closed and prevent the drawer from sliding out; the slot 8 can provide 10N of pulling force to the slide rail in the direction of the drawer being pulled out; when the slide rail is pulled out to its maximum stroke, the spring 11 releases its elasticity, so that the movable rod 6 cooperates with the step of the outer rail 3, which can lock the state and prevent the slide rail from retracting.

[0034] Apply 2N of force to the unlock lever of movable rod 6 to make movable rod 6 lift up, thereby releasing the locked state and retracting the slide rail;

[0035] The optional closed retaining function can be achieved by installing and removing the roller 7, rotating shaft 10, spring 11, movable rod 6, and positioning steel plate 5 on the basis of a non-functional ordinary slide rail. This optional component has a simple structure, is easy to install, and provides pull-out locking function and closed retaining function, enabling flexible switching between different slide rail configurations.

[0036] Since the roller 7 is fixed to the movable rod 6 via the rotating shaft 10, and the spring 11 is fixed between the movable rod 6 and the positioning steel plate 5, the control assembly consisting of the spring 11, the movable rod 6, and the roller 7 ensures that when the slide rail is fully closed, the roller 7 is locked in place, effectively preventing automatic slippage and reducing friction between metal parts. This enhances the locking control capability of the slide rail.

[0037] Since the movable rod 6 is connected to the positioning steel plate 5 by screws 9, and the positioning steel plate 5 is connected to the inner rail 1 by screws 9, when the slide rail is fully opened, the movable rod 6 flips down under the elastic force of the spring 11, achieving a check-back effect and effectively locking the slide rail, thus improving the overall stability of the slide rail. When it is necessary to reset, simply move the unlocking lever on the movable rod 6 to reset it.

[0038] The movable rod 6, spring 11, and positioning steel plate 5 can be completely removed by loosening screw 9 to restore the ordinary slide rail structure, thereby flexibly meeting the needs of high-end and low-end optional configurations, and facilitating installation and maintenance.

[0039] In summary, this utility model provides a slide rail with a controller and rollers 7. The rollers 7 are used for locking, and the movable rod 6 is used for anti-return. This can effectively deal with the problem of slide rail uncontrolled unfolding or automatic sliding back in the working scenario, improve the reliability of the action, and improve the sliding efficiency.

Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
