Description

Technical Field

[0001] This utility model relates to the field of monitor bracket technology, specifically to a slide rail limiting structure with two-phase obstruction point beaded nest. Background Technology

[0002] Monitor stands primarily serve as supports for the bottom of the monitor screen. Generally, besides supporting the monitor screen, they must also allow for height adjustment to ensure the screen is positioned at a comfortable viewing height. Currently, most monitor height adjustment slides on the market only have one stop on the beaded bracket, installed at the top and using the screw head on the inner frame for positioning. During installation, the orientation is crucial; incorrect installation with the non-stopped bracket facing upwards risks the inner frame detaching during subsequent vertical movement. Furthermore, the zeroing distance between the beaded bracket and the screw head on the inner frame is relatively short, easily leading to asynchrony and resulting in greater movement force at the top, causing a poor user experience.

[0003] Based on the above, this utility model proposes a slide rail limiting structure with a two-phase obstruction point bead nest, which can effectively solve the above problems. Utility Model Content

[0004] This utility model addresses the shortcomings of the existing technology by providing a slide rail limiting structure with a two-phase, different-point beaded nest.

[0005] This utility model is achieved through the following technical solution:

[0006] A slide rail limiting structure with a two-phase opposing stop bead nest includes an outer frame, an inner frame, steel balls, and a bead nest; the bead nest is disposed between the outer frame and the inner frame; the outer frame and the inner frame are slidably engaged by the steel balls and the bead nest; the upper and lower ends of the outer frame are respectively fixedly connected to outer frame stop points; the upper end of the bead nest is fixedly connected to an inwardly bent upper bead nest stop point, and the lower end of the bead nest is fixedly connected to a V-shaped lower bead nest stop point; the inner frame has multiple screw mounting holes, two of which are respectively fitted with an upper screw stop point and a lower screw stop point, and there is a safe distance between the upper screw stop point and the upper end of the inner frame.

[0007] According to the above technical solution, as a further preferred technical solution, multiple slots for installing steel balls are provided on both sides of the ball nest, and arc-shaped mounting surfaces that cooperate with and connect with the outer surface of the steel balls are respectively provided on both sides of the slots.

[0008] According to the above technical solution, as a further preferred technical solution, the inner side of the outer frame has a first groove that corresponds to and cooperates with the steel ball.

[0009] According to the above technical solution, as a further preferred technical solution, the outer side of the inner frame has a second sliding groove that corresponds to and cooperates with the steel ball.

[0010] According to the above technical solution, as a further preferred technical solution, the cross-sections of the first slide and the second slide are both arc-shaped.

[0011] According to the above technical solution, as a further preferred technical solution, the distance between the lower surface of the upper screw stop and the lower screw stop and the lower surface of the bead nest is less than the distance between the upper end of the upper screw stop and the lower surface of the bead nest.

[0012] According to the above technical solution, as a further preferred technical solution, the distance between the lower surface of the upper screw stop and the lower screw stop and the lower surface of the bead nest is less than the distance between the upper end of the lower screw stop and the lower surface of the bead nest.

[0014] According to the above technical solution, as a further preferred technical solution, the outer frame is provided with a plurality of first screw through holes, and the bead nest is provided with a plurality of second screw through holes.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0016] This utility model provides a slide rail limiting structure with two-phase non-stop bead nests. Through the interaction of the outer frame, inner frame, steel balls, and bead nests, the slide rail can slide smoothly, meeting the basic functional requirements of the slide rail. At the same time, the outer frame stop points at the top and bottom of the outer frame, the upper and lower bead nest stop points on the bead nest, and the upper and lower screw stop points on the inner frame form a multi-limiting structure through the cooperation of various stop points, effectively preventing the risk of the inner frame detaching due to the bead nest being installed backwards. Furthermore, there is a safe distance between the upper screw stop point and the upper end of the inner frame, making the force on the slide rail more reasonable during the sliding process, avoiding asynchronous phenomena, reducing the upper movement force, and improving the user experience. Meanwhile, setting the lower screw stop point as the main zeroing and reset point is more in line with ergonomics. When the device needs to be zeroed and reset, it can be pressed down, without having to lift it upwards and overcome the weight of the screen as in traditional structures.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0023] A sliding rail limiting structure with two-phase non-stopping bead nests includes an outer frame 1, an inner frame 2, steel balls 3, and bead nests 4; the bead nests 4 are disposed between the outer frame 1 and the inner frame 2; the outer frame 1 and the inner frame 2 are slidably engaged by the steel balls 3 and the bead nests 4; the upper and lower ends of the outer frame 1 are respectively fixedly connected to outer frame stop points 11; the upper end of the bead nest 4 is fixedly connected to an inwardly bent upper bead nest stop point 41, and the lower end of the bead nest 4 is fixedly connected to a V-shaped lower bead nest stop point 42; the inner frame 2 has multiple screw mounting holes 21, of which two screw mounting holes 21 are respectively installed with an upper screw stop point 5 and a lower screw stop point 6, and there is a safe distance between the upper screw stop point 5 and the upper end of the inner frame 2.

[0024] This invention utilizes the cooperative action of the outer frame 1, inner frame 2, steel balls 3, and bead nest 4 to enable the slide rail to slide smoothly, meeting basic slide rail functional requirements. Simultaneously, the outer frame stop points 11 at the top and bottom of the outer frame 1, the upper bead nest stop point 41 and lower bead nest stop point 42 on the bead nest 4, and the upper screw stop point 5 and lower screw stop point 6 on the inner frame 2 form a multi-limiting structure through the cooperation of these stop points, effectively preventing the risk of the inner frame 2 detaching due to the bead nest 4 being installed backwards. Furthermore, the upper screw stop point 5 has a safe distance from the upper end of the inner frame 2, making the force on the slide rail more reasonable during sliding, avoiding asynchronous phenomena, reducing the upper movement force, and improving the user experience. At the same time, setting the lower screw stop point 6 as the main zeroing and reset point is more ergonomic; when the device needs to be zeroed and reset, it can be pressed down, without needing to be pulled upwards and overcome the weight of the screen as in traditional structures.

[0025] Furthermore, in another embodiment, the two sides of the bead nest 4 are provided with a plurality of slots 43 for installing steel balls 3, and the two sides of the slots 43 are respectively provided with arc-shaped mounting surfaces 44 that are connected to the outer surface of the steel balls 3.

[0026] By setting the slot 43 and the arc-shaped mounting surface 44, the steel ball 3 can be installed more securely, ensuring that the steel ball 3 will not accidentally slide out of the slot 43 during the sliding process, thereby ensuring the stability and smoothness of the slide rail.

[0027] Furthermore, in another embodiment, the inner side of the outer frame 1 has a first groove 12 that corresponds to and engages with the steel ball 3. The outer side of the inner frame 2 has a second groove 22 that corresponds to and engages with the steel ball 3. The cross-sections of both the first groove 12 and the second groove 22 are arc-shaped.

[0028] By setting a first sliding groove 12 on the inner side of the outer frame 1 and a second sliding groove 22 on the outer side of the inner frame 2, both with arc-shaped cross sections, which correspond to and cooperate with the steel ball 3, the rolling of the steel ball 3 can be better guided, further improving the smoothness of the slide rail and reducing friction and jamming during the sliding process.

[0029] Furthermore, in another embodiment, the distance between the lower surfaces of the upper screw stop 5 and the lower screw stop 6 and the lower surface of the bead nest 4 is less than the distance between the upper end of the upper screw stop 41 and the lower surface of the bead nest 4. The distance between the lower surfaces of the upper screw stop 5 and the lower screw stop 6 and the lower surface of the bead nest 4 is less than the distance between the upper end of the lower screw stop 42 and the lower surface of the bead nest 4.

[0030] By setting the upper bead stop 41, and ensuring that the distance between the lower surfaces of the upper screw stop 5 and the lower screw stop 6 and the lower surface of the bead nest 4 is less than the distance between the upper end of the upper bead stop 41 and the lower surface of the bead nest 4, it is ensured that the upper bead stop 41 cooperates with the upper screw stop 5 and the lower screw stop 6 to achieve normal limiting in the normal installation direction; by setting the upper bead stop 41, and ensuring that the distance between the lower surfaces of the upper screw stop 5 and the lower screw stop 6 and the lower surface of the bead nest 4 is less than the distance between the upper end of the lower bead stop 42 and the lower surface of the bead nest 4, when the installer mistakenly installs the bead nest with the end that should be facing down facing up, the V-shaped lower bead stop 42 can also interact with the corresponding structure on the inner frame 2 to prevent the inner frame 2 from moving excessively and detaching from the frame.

[0031] Furthermore, in another embodiment, the outer frame 1 has a plurality of fixing holes 13.

[0032] By providing multiple mounting holes 13, it is easy to fix the outer frame 1 to other parts of the monitor stand, increasing the flexibility and stability of the installation.

[0033] Furthermore, in another embodiment, the outer frame 1 has a plurality of first screw through holes 14, and the bead nest 4 has a plurality of second screw through holes 45.

[0034] By opening multiple first screw through holes 14 on the outer frame 1 and multiple second screw through holes 45 on the bead nest 4, when the slide rail needs to be fixed, it is convenient for the screws to pass through the first screw through holes 14 or the second screw through holes 45 during installation, thereby making it convenient for the outer frame 1 and the inner frame 2 to be fixed to other parts of the monitor bracket by screws.
