Description

Technical Field

[0001] The present application relates to the field of mechanical research and development technology, and in particular to a hook assembly and device and a method for disassembling and assembling the same. Background Art

[0002] At present, when developing and designing mechanical equipment with more complex structures and more powerful functions, people usually pay more attention to the design of its internal structure reliability and performance, while ignoring the design of functional components such as hooks for installation and disassembly. This kind of design is generally ranked very low in the design priority of the whole set of equipment, and is rarely designed independently. Generally, it can only be designed using the remaining fragmented space after the completion of other structural designs. This will not only result in the function and reliability of the hook components not being guaranteed as a priority, but also lead to its complex structure, inconvenient operation, cumbersome and unclear operation steps, etc., and even when disassembling, it is necessary to remove other blocking components around it before using it to realize equipment disassembly. Not only is the operation cumbersome, but it is also time-consuming and labor-intensive, with low disassembly and assembly efficiency, and it is not convenient for subsequent improvement, maintenance, and replacement. Summary of the invention

[0003] The present application provides a hook assembly and device as well as a method for disassembling and assembling the same, so as to solve the problems of poor functional reliability, complex structure, and difficulty and inconvenience in realizing the installation and disassembly functions of the existing hook structure.

[0004] The first aspect of the present application provides a hook assembly for installation on a device frame, comprising:

[0005] A collision hook and a rotating hook installed on the equipment frame, and a supporting and fixing device arranged near the collision hook and the rotating hook and provided with a clamping ring;

[0006] The collision hook comprises: a shell formed by a first side plate and a second side plate arranged opposite to each other, a third side plate and a fourth side plate arranged opposite to each other, and a top plate and a bottom plate arranged opposite to each other, a first spring having one end arranged in contact with the inner wall of the first side plate, the other end of the first spring being arranged in contact with the first side wall of a sliding card, a second side wall of the sliding card arranged opposite to the first side wall thereof extending outwardly and provided with an inclined surface stopper passing through a first through hole of the second side plate, the inclined surface of which is exposed.

[0007] A top wall is connected between the first side wall and the second side wall, an L-shaped rotating hook is provided in the space between the first side wall and the second side wall, a first right-angled side of the L-shaped rotating hook is arranged in contact with the first side wall, and a second right-angled side of the L-shaped rotating hook is arranged in contact with the bottom plate, a first rotating pin is provided through the connection between the first right-angled side and the second right-angled side, two ends of the first rotating pin are rotatably connected to the third side plate and the fourth side plate respectively, and an exposed disassembly through hole is provided at the position where the bottom plate is in contact with the second right-angled side,

[0008] A first L-shaped hook is provided along the bottom end of the second side plate, which is connected by the first straight plate and the second straight plate. One end of the first straight plate is fixedly connected to the bottom end of the second side plate. The second straight plate is parallel to and opposite to the second side plate. The inclined surface stopper is in contact with the second straight plate. A spacing is left between the first straight plate and the inclined surface stopper.

[0009] The rotating hook comprises: a fixing seat, one end face of which is rotatably connected to a first end of a rotating clamp through a second rotating pin, a second end face of the rotating clamp opposite to the first end is fixedly connected to a side of a third straight plate of a second L-shaped hook that is away from a fourth straight plate connected thereto, and further comprises a U-shaped slot located on a side of the third straight plate away from the rotating clamp, the opening of which faces the fourth straight plate, and at least one end of the opening is arranged to be opposite to and in contact with the fourth straight plate, and the U-shaped slot can form a closed structure with the fourth straight plate,

[0010] It also includes a button and a second spring sleeved outside the first column, the end surface of the button is extended with the first column, the cross-sectional area of ​​the first column is smaller than the cross-sectional area of ​​the button, and the end of the first column away from the button is assembled and fixed with the third straight plate.

[0011] Compared with the prior art, the collision hook and the rotating hook of the hook assembly provided in the present application can be locked with the snap ring on the supporting fixing device respectively, and the outer shell wall of the collision hook and the fixing seat of the rotating hook can be fixedly installed with the equipment frame respectively. During installation, the button of the rotating hook can be pressed first, and the end of the first column connected to it pushes the third straight plate of the second L-shaped hook to move in the same direction as the movement direction of the first column, and at the same time compresses the second spring sleeved outside the first column to store elastic potential energy. At the same time, the movement of the third straight plate drives the fourth straight plate connected to it to move in the direction away from the U-shaped slot, so that the opening of the U-shaped slot is exposed. At this time, the snap ring is inserted into the U-shaped slot, and the button is released to release the elastic potential energy stored in the second spring, so that the fourth straight plate moves in the direction close to the U-shaped slot, so that at least one end of the U-shaped slot is relatively attached to the side of the fourth straight plate. At the same time, its opening is closed to lock it; then the edge of another snap ring is applied with force to collide with the inclined surface of the inclined surface block exposed on the collision hook, so that it automatically shrinks, and the force is transmitted to the first side wall in sequence through the second side wall connected to it and the top wall connected to the first side wall and the second side wall. The first side wall compresses the first spring arranged in contact with it to store elastic potential energy. After the aforementioned snap ring enters the gap between the first straight plate and the inclined surface block through the retracted inclined surface block, the inclined surface block automatically rebounds to the position abutting against the second straight plate to be locked because there is no external force applied by the snap ring and the first spring automatically releases its stored elastic potential energy.When disassembling, the user can first pass through the disassembly through hole and apply force to touch the second right-angled side of the L-shaped rotating hook arranged opposite to the disassembly through hole, and the second right-angled side drives the first right-angled side connected to it to rotate simultaneously through the first rotating pin, and the first right-angled side pushes the first side wall of the sliding card arranged in contact with it to move in the direction of compressing the first spring, so that the first spring stores elastic potential energy, and at the same time, the first side wall successively drives the top wall connected to it, the second side wall connected to the top wall, and the inclined surface block connected to the second side wall to move in the same direction, so that the inclined surface block retracts, and the snap ring locked in the spacing is pulled out and removed, and the user withdraws the external force applied to the second right-angled side, and the second right-angled side of the aforementioned L-shaped rotating hook has no force applied, and at the same time the aforementioned first spring is automatically released. The stored elastic potential energy causes the second right-angled side to automatically rotate to a position where it is in contact with the disassembly through hole of the bottom plate of the shell; then the button of the rotating hook is pressed, and the end of the first column connected to it pushes the third straight plate of the second L-shaped hook to move in the same direction as the movement direction of the first column, while compressing the aforementioned second spring and storing elastic potential energy. At the same time, the movement of the third straight plate drives the fourth straight plate connected to it to move in a direction away from the U-shaped slot, so that the opening of the U-shaped slot is exposed. At this time, the snap ring locked in the U-shaped slot is pulled out and disassembled, and the aforementioned button is released to release the elastic potential energy stored in the aforementioned second spring, so that the fourth straight plate moves in a direction close to the U-shaped slot, so that at least one end of the U-shaped slot is in contact with the side of the fourth straight plate, so that the opening is closed.

[0012] It can be seen from the above that, through the cooperation of the collision hook and the rotating hook of the hook assembly provided by the present application, the device can be firmly locked to ensure its locking reliability, and the collision hook and the rotating hook have a compact structure, strong force transmission capacity, simple user operation, clear process, and are convenient for users to disassemble, install and repair the device. In addition, the hook assembly can be directly disassembled from the equipment frame, and is an independent structure that can be separated from the equipment frame, which is convenient for the later improvement, maintenance, replacement, etc. of the hook assembly, and the buttons, inclined blocks and disassembly holes that need to be activated by the user are designed as a structure with the control surface exposed to the outside, which can be easily touched by the user, which is convenient for the user to operate directly without removing other shielding parts, and also because it is an independent structure that can be separated from the equipment frame, there is no need to use the remaining fragmented space after the design of other structures of the overall equipment is completed for design, but it is designed with the assembly reliability and disassembly convenience of its own structure as the priority to ensure its locking reliability.

[0013] Furthermore, a stop gasket is fixedly connected to the inner wall of the first side plate of the housing, and is penetrated by a cylindrical through hole with an opening toward the sliding clamp;

[0014] The first side wall of the sliding card extends toward the cylindrical through hole and is provided with a second column, the cross-sectional area of ​​the second column is smaller than the cross-sectional area of ​​the cylindrical through hole, the first spring is sleeved on the outer wall of the second column, and one end face of the first spring abuts against the stop gasket.

[0015] The anti-retraction gasket with a cylindrical through hole can determine the setting position of the first spring, which can better ensure the normal operation and stable function of the first spring. The second column can be inserted into the cylindrical through hole, and the first spring can be sleeved outside it, which can further determine the compression path of the first spring, ensure and maximize the function, and further ensure the accuracy of the direction of the transmitted force.

[0016] Furthermore, the cylindrical through hole is located at the center of the anti-retraction gasket; and / or

[0017] The orthographic projection of the first cylinder falls on the center position of the orthographic projection of the button.

[0018] In this way, when pressing the button, more effort is saved and the force transmitted is more uniform, and the effect achieved is better; similarly, the force transmitted to the anti-retraction gasket by the first spring is also more uniform, more effort is saved and the effect achieved is better.

[0019] Furthermore, a second through hole is provided at a position where the second straight plate of the first L-shaped hook is opposite to the inclined surface stopper, and the inclined surface stopper can partially pass through the second through hole.

[0020] In this way, the inclined surface stopper and the second straight plate can be more firmly abutted and locked, and are not easy to loosen, thereby further ensuring the safety of the equipment.

[0021] Furthermore, the disassembly through hole is arranged near the free end of the second right-angled side, and the free end is the end away from the connection between the first right-angled side and the said.

[0022] In this way, according to the principle of leverage, the same or greater transmission effect can be achieved with less force.

[0023] Furthermore, the supporting and fixing device comprises a first guide rail and a second guide rail respectively arranged near the collision hook and the rotating hook, and at least two clamping rings are evenly arranged on the assembly edges near the first guide rail and the second guide rail, respectively.

[0024] Correspondingly, at least two of the collision hooks and two of the rotating hooks are provided.

[0025] Arranging a plurality of snap rings allows the collision hook or the rotating hook to be hung at will, on the one hand, and can also ensure the stability of the hanging, on the other hand.

[0026] Furthermore, the assembly edge is an arc-shaped structure.

[0027] On the one hand, since the assembly edge is exposed and located in a position accessible to the user, setting it into an arc-shaped structure to reduce edges and corners can prevent users from being scratched and ensure their safety. On the other hand, the arc-shaped structure can reduce friction and is more conducive to locking with a collision hook or a rotating hook.

[0028] Furthermore, the first guide rail and the second guide rail are respectively arranged close to two opposite sides of the equipment frame, and each of the collision hooks and each of the rotating hooks are evenly arranged on two opposite sides of the equipment frame.

[0029] Locking the two opposite sides of the equipment frame and evenly hanging and arranging the collision hooks and the rotating hooks can further ensure the stability and locking firmness of the equipment, and further ensure its safety.

[0030] A second aspect of the present application provides a device, including a device frame, on which is installed any of the hook assemblies described above, and the collision hook and the rotating hook are respectively installed on opposite sides of the device frame.

[0031] This device can not only ensure the firmness and reliability of its locking, and can be disassembled, installed and repaired efficiently and conveniently, but also ensure its safety and stability.

[0032] The third aspect of the present application provides a disassembly and assembly method, including an installation method and a removal method, including the device, the installation method comprising: holding the device frame with one hand, pressing the button of the rotating hook with the other hand, clamping the clamp ring into the U-shaped clamping groove of the rotating hook, and then releasing the button; rotating the device frame around the rotating hook to the other clamp ring and applying force to collide with the inclined surface stopper to automatically retract it, so that the clamp ring is clamped into the gap between the first straight plate and the inclined surface stopper, and the inclined surface stopper automatically rebounds to a position abutting against the second straight plate;

[0033] The disassembly method includes: holding the device frame with one hand, and passing the other hand through the disassembly through hole and applying force to touch the second right-angled side of the L-shaped rotating hook, the inclined stopper retracts, and after the snap ring is removed from the gap between the first straight plate and the inclined stopper, the inclined stopper automatically rebounds to a position abutting against the second straight plate; holding the device and rotating it around the rotating hook to its natural hanging position, releasing the hand and then removing the cable connected to the device; pressing the button, pulling the snap ring out of the U-shaped slot and removing it, and then releasing the button.

[0034] The installation and removal by the disassembly and assembly method can not only ensure the firmness and reliability of the equipment locking, but also make good use of the rotatable function of the rotating hook, making the disassembly and assembly process more labor-saving and convenient. Since the weight of the general equipment itself is relatively large, the collision hook is removed first during disassembly. Due to the rotatable function of the rotating hook and the rotating hook is still in a locked state at this time, the equipment can be rotated and drooped naturally, such as rotating 90 degrees, and can withstand the weight of the equipment to ensure that it does not fall. At this time, the user can concentrate on efficiently removing the cables connected to the equipment, and the cable removal work can be completed by one person, without the need for one person to hold the equipment. This can ensure that the equipment is safer, improve work efficiency, save labor, and is not easy to damage the hook assembly, thereby extending the service life of the equipment and the hook assembly.

A first L-shaped hook 36 may extend along the bottom end of the aforementioned second side plate 312, and one end of the first straight plate 361 thereof is fixedly connected to the bottom end of the second side plate 312, and the other end thereof is fixedly connected to the bottom end of the second straight plate 362, and the second straight plate 362 is parallel to and opposite to the second side plate 312, so that the aforementioned bevel stopper 3321 may abut against the second straight plate 362, and a spacing is left between the first straight plate 361 and the bevel stopper 3321.

[0104] Preferably, a second through hole 3621 may be provided at a position where the second straight plate 362 of the first L-shaped hook 36 is opposite to the inclined surface stopper 3321, so that the inclined surface stopper 3321 can partially pass through the second through hole 3621. In this way, the inclined surface stopper 3321 and the second straight plate 362 can be more firmly locked and not easily loosened, thereby further ensuring the safety of the device.

[0105] like Figure 4-6 As shown, the aforementioned rotating hook 4 may include: a fixing seat 41 fixedly connected to the aforementioned equipment frame 1, specifically, the fixing seat can be fixed to the equipment frame 1 by a pin 38, one end face of the fixing seat 41 is rotatably connected to a first end 431 of a rotating clamp 43 by a second rotating pin 42, the second end face 432 of the rotating clamp 43 is fixedly connected to a side of a third straight plate 441 of a second L-shaped hook 44, the side of the third straight plate 441 is a side away from the fourth straight plate 442, the aforementioned first end 431 and the aforementioned second end face 432 are arranged opposite to each other, and the second L-shaped hook 44 is formed by connecting the aforementioned third straight plate 441 and the aforementioned fourth straight plate 442 to form an L-shaped structure.

[0106] The aforementioned rotating hook 4 may also include a U-shaped card slot 45 located on the side of the aforementioned third straight plate 441 away from the aforementioned rotating card member 43, the opening 451 of the U-shaped card slot 45 faces the aforementioned fourth straight plate 442, and the U-shaped card slot 45 may form a closed structure with the fourth straight plate 442.

[0107] Compared with the prior art, the collision hook 3 and the rotating hook 4 of the hook assembly provided in the embodiment of the present application can be respectively locked with the clamping ring 24 on the supporting fixing device 2, and the outer wall of the shell 31 of the collision hook 3 and the fixing seat 41 of the rotating hook 4 can be respectively fixedly installed with the equipment frame 1. During installation, the button 461 exposed outside the rotating hook 4 can be pressed first, and the end of the first column 462 connected thereto can push the third straight plate 441 of the second L-shaped hook 44 to move in the same direction as the movement direction of the first column 462, and at the same time, the second spring 47 sleeved outside the first column 462 can be compressed to store elastic potential energy. At the same time, the movement of the third straight plate 441 drives the fourth straight plate 442 connected thereto to move in a direction away from the U-shaped slot 45, so that the opening 451 of the U-shaped slot 45 is exposed. At this time, the aforementioned snap ring 24 is inserted into the U-shaped slot 45, and the aforementioned button 461 is released to release the elastic potential energy stored in the aforementioned second spring 47, so that the fourth straight plate 442 moves in a direction close to the U-shaped slot 45, so that at least one end 452 of the U-shaped slot 45 is relatively attached to the side surface of the fourth straight plate 442. At the same time, its opening 451 is closed to lock it; then the edge of another snap ring 24 is applied with force to collide with the exposed inclined surface of the inclined surface block 3321 of the collision hook 3, so that it automatically shrinks, and transmits force to the first side wall 331 through the second side wall 332 connected to it and the top wall 333 connected to the first side wall 331 and the second side wall 332 in sequence. The first side wall 331 compresses the first spring 32 set in contact with it to store elastic potential energy. After the aforementioned snap ring 24 enters the gap between the first straight plate 361 and the inclined surface block 3321 through the retracted inclined surface block 3321, the inclined surface block 3321 automatically rebounds to the position abutting against the second straight plate 362 to lock it.

The second right-angled side 342 of the aforementioned L-shaped rotating hook 34 has no force applied, and at the same time, the aforementioned first spring 32 automatically The elastic potential energy stored therein is released, so that the second right-angled side 342 automatically rotates to a position where it is in contact with the disassembly through hole 3151 of the bottom plate 315 of the housing 31; then the exposed button 461 of the rotating hook 4 is pressed, and the end of the first column 462 connected thereto pushes the third straight plate 441 of the second L-shaped hook 44 to move in the same direction as the movement direction of the first column 462, and at the same time compresses the aforementioned second spring 47 and stores elastic potential energy, and at the same time, the movement of the third straight plate 441 The fourth straight plate 442 connected thereto is moved in a direction away from the U-shaped slot 45, so that the opening 451 of the U-shaped slot 45 is exposed. At this time, the snap ring 24 locked in the U-shaped slot 45 is pulled out and disassembled, and the button 461 is released to release the elastic potential energy stored in the second spring 47, so that the fourth straight plate 442 moves in a direction close to the U-shaped slot 45, so that at least one end of the U-shaped slot 45 is relatively attached to the side surface of the fourth straight plate 442, so that the opening 451 is closed.

[0109] As can be seen from the above, through the cooperation of the collision hook 3 and the rotating hook 4 of the hook assembly provided in the embodiment of the present application, the device can be firmly locked to ensure its locking reliability, and the collision hook 3 and the rotating hook 4 have a compact structure, strong force transmission capacity, simple user operation, clear process, and are convenient for users to disassemble, install and repair the device. In addition, the hook assembly can be directly disassembled from the device skeleton 1, and is an independent structure that can be separated from the device skeleton 1, which is convenient for the later improvement, maintenance, replacement, etc. of the hook assembly, and the button 461, the inclined block 3321 and the disassembly through hole 3151 that need to be activated by the user are designed to be a structure with the control surface exposed to the outside, which can be easily touched by the user, which is convenient for the user to directly operate without removing other shielding parts, and also because it is an independent structure that can be separated from the device skeleton 1, there is no need to use the remaining fragmented space after the design of other structures of the overall device is completed for design, but it is designed with the assembly reliability and disassembly convenience of its own structure as the priority to ensure its locking reliability.

[0110] The embodiment of the present application also provides a device, including the aforementioned device frame 1, which is equipped with the aforementioned hook assembly, and the collision hook 3 and the rotating hook 4 are respectively installed on opposite sides of the device frame 1. This device can not only ensure the firmness and reliability of its locking, and can be disassembled, installed and repaired efficiently and conveniently, but also ensure its safety and stability.

[0111] The embodiment of the present application also provides a disassembly and assembly method, including an installation method and a removal method, including the aforementioned hook assembly and the aforementioned device, the installation method comprising: holding the device frame with one hand, pressing the button of the rotating hook with the other hand, inserting the clamping ring into the U-shaped clamping groove of the rotating hook, and then releasing the button; rotating the device frame around the rotating hook to another clamping ring and applying force to collide with the inclined surface stopper to automatically retract it, so that the clamping ring is inserted into the gap between the first straight plate and the inclined surface stopper, and the inclined surface stopper automatically rebounds to a position abutting against the second straight plate;

[0112] The disassembly method includes: holding the device frame with one hand, and passing the other hand through the disassembly hole and applying force to touch the second right-angled side of the L-shaped rotating hook, the inclined block retracts, and after the snap ring is removed from the gap between the first straight plate and the inclined block, the inclined block automatically rebounds to a position abutting against the second straight plate; holding the device and rotating it around the rotating hook to its natural hanging position, such as rotating 90 degrees, releasing the hand and then removing the cable connected to the device; pressing the button, pulling the snap ring out of the U-shaped slot and removing it, and then releasing the button.

[0113] The installation and removal by the disassembly and assembly method can not only ensure the firmness and reliability of the equipment locking, but also make good use of the rotatable function of the rotating hook, making the disassembly and assembly process more labor-saving and convenient. Since the weight of the general equipment itself is relatively large, the collision hook is removed first during disassembly. Due to the rotatable function of the rotating hook and the rotating hook is still in a locked state at this time, the equipment can be rotated and drooped naturally, such as rotating 90 degrees, and can withstand the weight of the equipment to ensure that it does not fall. At this time, the user can concentrate on efficiently removing the cables connected to the equipment, and the cable removal work can be completed by one person, without the need for one person to hold the equipment. This can ensure that the equipment is safer, improve work efficiency, save labor, and is not easy to damage the hook assembly, thereby extending the service life of the equipment and the hook assembly.

[0114] Further, a stop gasket 37 is fixedly connected to the inner wall of the first side plate 311 of the housing 31, which is penetrated by a cylindrical through hole 371 with an opening toward the sliding card 33, and the first side wall 331 of the sliding card 33 extends toward the cylindrical through hole 371 and is provided with a second column 3311, the cross-sectional area of ​​the second column 3311 is smaller than the cross-sectional area of ​​the cylindrical through hole 371, and the outer wall of the second column 3311 is sleeved with the first spring 32, and one end face of the first spring 32 abuts against the stop gasket 37. The stop gasket with a cylindrical through hole can determine the setting position of the first spring, which can better ensure the normal operation and stable function of the first spring. The second column is set and can be inserted into the cylindrical through hole, and the first spring can be sleeved outside it, which can further determine the compression path of the first spring, ensure and maximize the function, and further ensure the accuracy of the direction of the transmitted force.

[0115] In a preferred embodiment, the cylindrical through hole 371 is located at the center of the anti-retraction gasket 37. In another preferred embodiment, the orthographic projection of the first column 462 falls on the center of the orthographic projection of the button 461. In this way, when pressing the button, it is more labor-saving and the force transmitted is more uniform, and the effect is better; similarly, the force transmitted to the anti-retraction gasket by pushing the first spring is more uniform, which saves more labor and achieves better effect.

[0116] like Fig.10 and Fig.11 As shown, the assembly edge 23 of the first guide rail 21 and / or the second guide rail 22 may be an arc-shaped structure. On the one hand, since the assembly edge 23 is exposed and located at a position accessible to the user, setting it into an arc-shaped structure reduces the edges and corners, which can prevent the user from being scratched and ensure the user's safety; on the other hand, the arc-shaped structure can reduce friction and is more conducive to locking with the collision hook 3 or the rotating hook 4. In addition, the shape of the hole of the aforementioned snap ring is not specifically limited here, and can be a square hole, a round hole, an irregular hole, etc.
