Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically a hinge that can be quickly disassembled and assembled. Background Technology

[0002] As is well known, a hinge, also known as a joint, is a mechanical device used to connect two solid objects and allow relative rotation between them. It is widely used in daily life and industrial production, playing a crucial role in the proper functioning of various equipment and furniture.

[0003] In existing hinge technology scenarios, there is a common problem of cumbersome disassembly operations. The installation structure of existing hinges is mostly a "fully bolted" mode: its base (corresponding to the mounting plate-like component of this utility model) needs to be rigidly connected to an external fixed object (such as a cabinet frame or equipment rack) by multiple bolts, and the movable block needs to be fixed to an external movable object (such as a cabinet door or equipment door) by bolts. Under this structure, when it is necessary to disassemble the hinge, the staff has to unscrew multiple bolts on the base and the movable block one by one, which wastes time and reduces work efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a hinge that can be quickly disassembled and assembled.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hinge that can be quickly disassembled and assembled, comprising a mounting plate, a hinge seat, a movable block, and a connecting mechanism. The hinge seat is connected to the mounting plate via the connecting mechanism. The movable block is hinged to the hinge seat and has a mounting hole. The connecting mechanism includes a limiting groove, a limiting block, a square groove, an electric push rod, a sliding groove, a slider, a locking block, and a through groove. The limiting groove is located on the mounting plate. One end of the electric push rod is connected to the hinge seat, and the other end of the electric push rod is connected to one end of the limiting block. The other end of the limiting block extends into the limiting groove. The sliding groove is located on the inner wall of the hinge seat. One end of the slider extends into the sliding groove. One end of the locking block is connected to the slider. The through groove is located at the bottom of the hinge seat. The other end of the locking block passes through the through groove and extends into the mounting plate. The mounting plate has a locking groove that matches the locking block. The square groove is located on the inner wall of the sliding groove, and one end of the slider extends into the square groove.

[0008] To improve stability, this utility model is improved by having two mounting holes, which are symmetrically arranged.

[0009] To improve stability, this invention is improved by matching the slider with the groove.

[0010] To improve stability, this utility model is improved by matching the limiting block with the square groove.

[0011] To improve the strength of the mounting plate, this utility model is improved by using alloy steel as the mounting plate material.

[0012] To improve the connection effect, the present invention is improved by fixing the card block to the slider.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a hinge that can be quickly disassembled and assembled, which has the following advantages:

[0015] This hinge, which can be quickly disassembled and assembled, greatly simplifies the disassembly and assembly process and improves operational efficiency: during installation, only the mounting plate and the movable block need to be fixed, and the limit block can be completed by driving the electric push rod; during disassembly, there is no need to remove the bolts on the mounting plate, only to remove the bolts on the movable block, control the electric push rod to reset and push the slider to separate the hinge seat from the mounting plate, avoiding the need to repeatedly tighten multiple bolts, reducing operation steps and time costs;

[0016] The structural design ensures high stability: the symmetrical double mounting holes make the connection of the moving blocks more stable; the matching design of the slider and the slide, the limit block and the square groove ensures that the movement of each component is precise and without deviation; the fixed connection between the locking block and the slider enables synchronous action; and the alloy steel mounting plate provides strong load-bearing capacity to avoid deformation and breakage after long-term use.

[0017] Balancing flexible rotation with reliable power supply: The "cylinder-hole" hinge structure allows the movable block to rotate smoothly. Combined with an electric actuator powered by external AC power, it not only meets the relative rotation requirements of the components but also provides stable power for the limit function, comprehensively improving the practicality and durability of the hinge.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 A hinge that can be quickly disassembled and assembled includes a mounting plate 1, a hinge seat 2, a movable block 3, and a connecting mechanism 5. The hinge seat 2 is connected to the mounting plate 1 via the connecting mechanism 5. The movable block 3 is hinged to the hinge seat 2. The movable block 3 has a mounting hole 4. The connecting mechanism 5 includes a limiting groove 6, a limiting block 7, a square groove 8, an electric push rod 9, a sliding groove 10, a slider 11, a locking block 12, and a through groove 13. The limiting groove 6 is formed on the mounting plate 1. One end of the electric push rod 9 is connected to the hinge seat 2, and the other end of the electric push rod 9... One end of the slider 11 is connected to one end of the limiting block 7, and the other end of the limiting block 7 extends into the limiting groove 6. The sliding groove 10 is formed in the inner wall of the hinge seat 2. One end of the slider 11 extends into the sliding groove 10. One end of the locking block 12 is connected to the slider 11. The through groove 13 is formed at the bottom of the hinge seat 2. The other end of the locking block 12 passes through the through groove 13 and extends into the mounting plate 1. The mounting plate 1 has a locking groove that matches the locking block 12. The square groove 8 is formed in the inner wall of the sliding groove 10, and one end of the slider 11 extends into the square groove 8.

[0025] Working principle

[0026] Installation procedure: as follows Figure 1As shown, the operator first uses bolts to fix the alloy steel mounting plate 1 to a designated fixed object (such as a cabinet side panel or equipment rack), ensuring that the mounting plate 1 is tightly fitted to the object surface without any looseness. Then, the entire hinge is powered on (it needs to be connected to external mains power through the equipment's preset wiring terminals, and equipped with an overload protection switch to prevent short circuits and provide stable power to the electric push rod 9). The electric push rod 9 is then activated to extend, causing the limit block 7 to move along the preset direction. Since the limit groove 6 on the mounting plate 1 has a reserved travel range to accommodate the movement of the limit block 7, the limit block 7 can smoothly extend into the limit groove 6 and move a certain distance, while simultaneously sliding along the square groove 8 on the inner wall of the hinge seat 2, finally passing through the square groove 8 and precisely abutting. At the top of slider 11—because the size of limit block 7 and square groove 8 are perfectly matched, they can form a stable longitudinal limit on slider 11, preventing slider 11 from sliding accidentally during subsequent use. Finally, the staff fixes movable block 3 to another movable object to be connected (such as cabinet door or equipment door) by bolts and two mounting holes 4 symmetrically set on movable block 3. At this point, the overall installation of the hinge is completed. It should be noted that the hinge seat 2 and movable block 3 are hinged through a "cylinder-circular hole" structure (the inner wall of hinge seat 2 is provided with a cylinder, and the movable block 3 is provided with a matching circular hole, which fits on the outer wall of the cylinder). After installation, movable block 3 can move flexibly around the cylinder to meet the relative rotation requirements of the components.

[0027] Disassembly procedure: When the hinge needs to be disassembled, the operator first uses a screwdriver to remove the connecting bolts on the movable block 3, so that the movable block 3 is completely separated from the corresponding moving object; then, the electric push rod 9 is retracted through the external control terminal, which drives the limit block 7 to disengage from the top of the slider 11 and gradually return to the initial position, so that the equipment returns to its original state. Figure 1 The disassembly preparation state is shown in the figure. Then, the operator pushes the slider 11 upward. Because the slider 11 matches the size of the slide groove 10, the slider 11 can slide smoothly along the slide groove 10, and simultaneously drive the locking block 12 fixedly connected to it to move upward. The locking block 12 first completely separates from the locking groove on the mounting plate 1, and then continues to move until it completely separates from the through groove 13 at the bottom of the hinge seat 2, releasing the lateral locking constraint between the hinge seat 2 and the mounting plate 1. Finally, the operator pulls the hinge seat 2 outward so that the limiting block 7 completely disengages from the limiting groove 6, and the hinge seat 2 and the movable block 3 can be removed together. The entire disassembly process only requires removing the bolts on the movable block 3, without removing the fixing bolts on the mounting plate 1, avoiding the operator from repeatedly tightening multiple bolts, greatly reducing the operation steps and significantly improving the disassembly efficiency.

[0028] In this embodiment, to effectively improve the stability of the connection between the movable block 3 and external moving objects (such as cabinet doors or equipment doors), and to prevent the movable block 3 from shifting or loosening due to uneven force during hinge rotation, thereby affecting the overall rotational accuracy and service life of the hinge, the installation structure of the movable block 3 is optimized in this embodiment: two mounting holes 4 are opened on the movable block 3, and the two mounting holes 4 are symmetrically distributed along the central axis of the movable block 3. This symmetrical double mounting hole design can fix the movable block 3 from both sides with two bolts, so that the weight of the external moving object and the force generated during rotation are evenly distributed to the two fixed points, effectively avoiding the problem of unilateral force and local deformation that is prone to occur with single mounting holes, providing a reliable guarantee for the stable connection between the movable block 3 and the external object, and also ensuring that the movable block 3 remains stable when rotating around the inner cylinder of the hinge seat 2, further improving the overall stability of the hinge.

[0029] In this embodiment, to effectively improve the stability and smoothness of the slider 11's movement and avoid jamming or offset due to insufficient fit between the slider 11 and the slide groove 10, which would affect the precise docking or separation of the locking block 12 and the mounting plate 1's slot, this embodiment is specifically designed so that the slider 11 and the slide groove 10 are perfectly matched in size and shape. The slider 11 can slide smoothly along the inner wall of the slide groove 10 without obvious gaps. This matching design can limit the movement trajectory of the slider 11 and prevent it from shifting or tilting to the left or right when sliding longitudinally. It ensures that when the slider 11 drives the locking block 12, the locking block 12 can be accurately aligned with the slot of the mounting plate 1 and the through groove 13 of the hinge seat 2. At the same time, it avoids wear caused by excessive friction between the slider 11 and the inner wall of the slide groove 10 due to shaking, providing reliable support for the stable operation of the connecting mechanism 5 and the overall assembly and disassembly efficiency of the hinge.

[0030] In this embodiment, to effectively improve the stability and positioning accuracy of the limiting block 7 during its movement, and to avoid deviation or jamming due to insufficient fit between the limiting block 7 and the square groove 8, thereby affecting the limiting effect on the slider 11, this embodiment is specifically designed so that the limiting block 7 and the square groove 8 are perfectly matched in size and shape. The limiting block 7 can slide smoothly along the inner wall of the square groove 8 without obvious gaps. This matching design can strictly limit the movement trajectory of the limiting block 7, preventing it from shifting up or down or tilting during lateral movement. It ensures that the limiting block 7 can accurately pass through the square groove 8 and stably abut against the top of the slider 11, forming a reliable longitudinal limit. At the same time, it avoids wear and tear caused by excessive friction between the limiting block 7 and the inner wall of the square groove 8 due to shaking, providing solid support for the stable operation of the connecting mechanism 5 and the overall assembly and disassembly efficiency of the hinge.

[0031] In this embodiment, the mounting plate 1, as the core load-bearing component connecting the hinge to external fixed objects (such as cabinet frames or equipment racks), needs to withstand the overall weight of the hinge, the force of the rotating block 3, and the external forces during assembly and disassembly for a long time. Its strength directly affects the overall connection stability and service life of the hinge. In order to effectively improve the strength and durability of the mounting plate 1 and avoid problems such as deformation and breakage after long-term use, this embodiment specifically selects alloy steel to make the mounting plate 1. Compared with ordinary steel, alloy steel has higher tensile strength, hardness, and fatigue resistance. It can stably bear various loads and resist minor collisions and friction wear during assembly and disassembly operations. At the same time, it can maintain structural stability for a long time, providing a reliable foundation for the hinge seat 2 to achieve precise docking through the connecting mechanism 5 and for the limit block 7 to move smoothly in the limit groove 6, further ensuring the stable use of the hinge throughout its entire life cycle.

[0032] In this embodiment, the locking block 12 and the slider 11 are the core linkage components of the connecting mechanism 5. They need to move synchronously to achieve precise engagement or disengagement of the hinge seat 2 and the mounting plate 1. The stability of their connection directly affects the hinge assembly and disassembly efficiency and the overall connection reliability. In order to effectively improve the connection effect of the two and avoid the locking block 12 and the slider 11 moving asynchronously due to loose connection, which would result in the locking block 12 not being able to accurately align with the mounting plate 1 slot or getting stuck when separating, this embodiment adopts a fixed connection method to assemble the locking block 12 and the slider 11 into one piece. This design can ensure that when the slider 11 slides along the slide groove 10, the locking block 12 always rises and falls synchronously with the slider 11, accurately completing the docking or disengagement with the mounting plate 1 slot. At the same time, it avoids the relative displacement and increased gap between the two during long-term use, providing a solid guarantee for the stable functioning of the connecting mechanism 5 and further improving the overall connection stability and durability of the hinge.
