Description

Technical Field

[0001] This utility model relates to the field of quick-release slide rail technology, and in particular to a slide rail quick-release mechanism. Background Technology

[0002] The way the slider is fixed in the groove often relies on the mechanical locking structure of screws and nuts (such as screws sliding along the groove and then tightening). Therefore, the slider position adjustment requires repeated disassembly and assembly of tools, which is cumbersome and inefficient.

[0003] Traditional bolt locking methods are cumbersome and time-consuming to operate, making it difficult to meet the efficiency requirements of frequent equipment disassembly and assembly. Furthermore, when the buckle is used on heavy objects and is subject to vibration and collision, it has poor resistance to vibration and impact, which can easily lead to insufficient locking force, causing equipment displacement and wear on connecting parts. Therefore, we propose a sliding groove quick-release mechanism for installation and fixing scenarios where heavy equipment requires rapid disassembly and assembly. Utility Model Content

[0004] In view of this, the embodiments of this utility model provide a sliding quick-release mechanism to solve the technical problem that the positioning methods of sliders and sliding grooves in the prior art mostly rely on bolts, nuts or snap-fit ​​structures for positioning, resulting in low efficiency.

[0005] An embodiment of this utility model provides a sliding quick-release mechanism, comprising:

[0006] A sliding frame has a sliding groove on its side, and a through hole that is vertical and communicates with the sliding groove is formed on the surface of the sliding frame;

[0007] The slider slides within the groove, and its surface has a limiting groove corresponding to the position of the through hole;

[0008] A locking rod rotates within the through hole, and the rod body of the locking rod is a semi-circular rod. The semi-circular rod corresponds to the shape of the limiting groove. By fitting the semi-circular rod and the limiting groove together, the sliding of the slider can be restricted. The arc surface of the semi-circular rod faces away from the sliding direction of the slider. The semi-circular rod can contact the slider in the groove and be rotated by the sliding and pressing of the slider.

[0009] The system includes a torsion spring and a torsion spring mounting base. The torsion spring is connected to the locking rod and slides within the groove via a slider. The slider slides and contacts and presses the semi-circular rod, causing the semi-circular rod to rotate within the through hole. This allows the semi-circular rod to be accommodated within the through hole, enabling the slider to continue sliding past the locking rod. When the limiting groove on the slider aligns with the position of the through hole, the locking rod rotates and resets under the torsion force of the torsion spring, causing the arcuate surface of the semi-circular rod to rotate and fit against the limiting groove, thus locking the slider.

[0010] Furthermore, a limiting block is fixedly connected to one end of the locking rod, and a protrusion is integrally provided on one side of the sliding frame corresponding to the limiting block. The limiting block abuts against the protrusion under the torsion force of the torsion spring.

[0011] Furthermore, the longitudinal section of the semicircular rod is semicircular, and the through hole is configured such that the portion communicating with the slide groove occupies half of the through hole, and the size of the communicating semicircular portion corresponds to that of the semicircular rod.

[0012] Furthermore, the outer wall of the slide frame is provided with a mounting box with an opening on one side, the through hole is connected to the inner cavity of the mounting box, and the torsion spring has two pins, one pin abuts against the inner wall of the mounting box, and the other pin is fixed to the torsion spring mounting seat.

[0013] Furthermore, a cross-shaped groove is provided on one side of the torsion spring mounting base, and one of the pins is embedded in the groove, so that one end of the torsion spring is fixed to the torsion spring mounting base.

[0014] Furthermore, one end of the locking rod is provided with a crescent block, and a crescent hole is passed through the torsion spring mounting seat, with the crescent block inserted into the crescent hole.

[0015] Furthermore, the locking rod is provided with an anti-reverse limiting block on its exterior. The anti-reverse limiting block rotates against the inner wall of the mounting box to prevent the locking rod from sliding out along the through hole toward the other side of the mounting box.

[0016] Furthermore, the mounting box is rectangular, and one of the pins abuts against any inner wall of the mounting box in a twisted state.

[0017] Furthermore, the opening surface of the mounting box is detachably sealed with an end cap by screws.

[0018] Furthermore, both ends of the slider are rounded, making the contact end between the slider and the semi-circular rod arc-shaped.

[0019] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: The sliding quick-release mechanism of this utility model achieves the function of quick assembly and disassembly through the ingenious cooperation of components such as the sliding frame, slider, locking rod, and torsion spring, making operation simple, time-saving, and labor-saving. When the slider slides, it presses the semi-circular rod of the locking rod, causing it to rotate and make room. When the slider limiting groove corresponds to the through hole, the torsion spring torque causes the locking rod to reset and lock the slider, ensuring a stable and reliable connection. The semi-circular rod and the semi-circular part of the through hole correspond in size, and after rotation, they fit tightly without loosening, enhancing the locking effect. The rounded corners at both ends of the slider reduce the contact stress with the semi-circular rod, reduce wear, make sliding smoother, avoid stress concentration, and improve service life. The structures of each component, such as the abutment of the limiting block and the protrusion, and the connection of the crescent block and the crescent hole, all enhance the stability and assembly efficiency of the mechanism. The overall structure is compact and reasonable, and can be widely used in scenarios with frequent assembly and disassembly, meeting the needs of convenience and having a long service life.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures. Also, it should be understood that, for ease of description, the dimensions of the various parts shown in the figures are not drawn to actual scale.

[0031] In the description of this utility model, it should be noted that the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0032] It should be further noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Please refer to Figures 1 to 4 The embodiments of this utility model provide a sliding quick-release mechanism mainly composed of a sliding frame 1, a slider 2, a locking rod 3, a torsion spring 4, a torsion spring mounting base 5, and a mounting box 6.

[0034] Example 1: The slide frame 1 is rectangular, and a long slide groove 12 is provided on its side along the length direction. A through hole 13 is provided on the surface of the slide frame 1 in a direction perpendicular to the slide groove 12. The through hole 13 is connected to the slide groove 12, and the shape of its connecting part is adapted to the semi-circular cross section of the semi-circular rod 32, occupying half of the space of the through hole 13.

[0035] Please see Figure 2 The slider 2 is a cuboid structure adapted to the slide groove 12. It can slide freely in the slide groove 12 along the length direction. A limiting groove 21 is opened on the surface of the slider 2. When the slider 2 slides to a specific position, the limiting groove 21 corresponds to the position of the through hole 13.

[0036] It should be noted that both ends of the slider 2 are rounded, so that the end that contacts the semi-circular rod 32 is arc-shaped. This allows the slider 2 to more smoothly compress the semi-circular rod 32 when it contacts it during sliding, reducing friction and wear, while avoiding stress concentration caused by sharp corners and extending the service life of the slider 2.

[0037] Please see Figures 4 to 5 In this embodiment, the locking rod 3 is rod-shaped in general, and the rod body in the middle position is a semi-circular rod 32. The arc surface of the semi-circular rod 32 faces the side away from the sliding direction of the slider 2.

[0038] One end of the locking rod 3 is fixedly connected to the limiting block 31, and the other end is provided with a crescent block 34. A protrusion 11 is integrally provided on one side of the slide frame 1 corresponding to the position of the limiting block 31. The shape of the protrusion 11 matches the limiting block 31 and is used to make the limiting block 31 abut against it when the locking rod 3 rotates and resets, thereby enhancing the stability of the mechanism.

[0039] It is understandable that when the limiting block 31 abuts against the protrusion 11, the horizontal plane of the semicircular rod 32 is perpendicular to the inner wall of the slide groove 12. At the same time, since the dimensions of the other semicircle of the semicircular rod 32 and the limiting block 31, which are not connected to the slide groove 12, are also compatible, when the semicircular rod 32 rotates into the limiting hole 12, its horizontal plane can be flush with the inner wall of the slide groove 12 to ensure that the slider 2 can slide smoothly.

[0040] Furthermore, the shape of the crescent block 34 is adapted to the crescent hole 51 on the torsion spring mounting base 5, and can be inserted into the crescent hole 51 to realize the connection between the locking rod 3 and the torsion spring mounting base 5.

[0041] Example 2, please refer to Figure 3 The difference from Embodiment 1 is that a rectangular mounting box 6 with an opening on one side is fixedly connected to the outer wall of the slide frame 1. The through hole 13 connects to the inner cavity of the mounting box 6. The opening surface of the mounting box 6 is detachably sealed with an end cap by screws, which facilitates maintenance operations on the internal components.

[0042] An anti-reverse limiting block 33 is also provided on the outside of the locking rod 3. When the locking rod 3 is installed in the through hole 13, the anti-reverse limiting block 33 is attached to the inner wall of the mounting box 6 and rotates, effectively preventing the locking rod 3 from sliding out along the through hole 13 toward the other side of the mounting box 6, and ensuring the stability of the mechanism during use.

[0043] Please see Figures 4 to 5The torsion spring 4 has two pins 41. One end of the torsion spring is connected to the locking rod 3 through the torsion spring mounting base 5. The other pin 41 of the torsion spring 4 abuts against the inner wall of the mounting box 6. When the locking rod 3 rotates, the torsion spring 4 generates torque, which allows the locking rod 3 to rotate when the slider 2 slides and squeezes the semi-circular rod 32. When the limiting groove 21 of the slider 2 corresponds to the position of the through hole 13, the torque of the torsion spring 4 pulls the locking rod 3 to rotate and reset, so that the arc surface of the semi-circular rod 32 fits against the limiting groove 21, locks the slider 2, and prevents it from sliding.

[0044] Specifically, a cross-shaped groove is provided on one side of the torsion spring mounting base 5, and one pin 41 of the torsion spring 4 is embedded in the groove, thereby realizing the fixed connection between the torsion spring 4 and the torsion spring mounting base 5.

[0045] When assembling the slide-type quick-release mechanism, firstly, insert the locking rod 3 entirely into the through hole 13 of the slide frame 1, ensuring that the semi-circular rod 32 is positioned where the through hole 13 connects to the slide 12. Then, restrict one end of the locking rod 3 within the mounting box 6 using the anti-reverse limiting block 33. Next, insert one pin 41 of the torsion spring 4 into the cross-shaped groove of the torsion spring mounting base 5. Then, by twisting the other pin 41 relative to the torsion spring mounting base 5, the torsion spring 4 acquires its initial torsional force. The other pin 41 of the torsion spring 4 is abutted against the inner wall of the mounting box 6. The torsion spring mounting seat 5 is housed in the mounting box 6 and inserted into the crescent hole 51 through it and the end of the locking rod 3 with the crescent block 34 is inserted, so that the crescent block 34 and the crescent hole 51 are tightly fitted, thereby realizing the connection between the locking rod 3 and the torsion spring mounting seat 5. At this time, the locking rod 3 rotates under the torque of the torsion spring 4. The initial position of the locking rod 3 is maintained by the limit block 31 at one end of the locking rod 3 abutting against the protrusion 11.

[0046] Connect the components to be connected to the slider 2, place the slider 2 into the slide groove 12 so that it can slide freely in the slide groove 12, and then slide the slider 2. During the sliding process of the slider 2, the end of the slider 2 will squeeze the semi-circular rod 32, causing the locking rod 3 to rotate against the torque of the torsion spring 4. The arc-shaped part of the semi-circular rod 32 rotates to fit against the inner wall of the through hole 13, so that the horizontal surface of the semi-circular rod 32 is flush with the inner wall of the slide groove 12, making room for the slider 2 to continue sliding. When the slider 2 slides to the position of the limiting groove 21 corresponding to the through hole 13, under the torque of the torsion spring 4, the locking rod 3 quickly rotates and resets, and the arc-shaped surface of the semi-circular rod 32 fits against the limiting groove 21, thereby locking the slider 2 firmly, realizing the quick connection and fixation between components;

[0047] If disassembly is required, simply rotate the limiting block 31 at one end of the locking rod 3 so that the semicircular rod 32 of the locking rod 3 rotates to release the locking state, and the slider 2 can slide out from the locked position to complete the disassembly.

[0048] In this document, the directional terms such as front, back, top, and bottom are defined based on the position of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.

[0049] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
