Description

Technical Field

[0001] This utility model relates to the field of rubber tray disassembly and assembly technology, specifically to a structure for disassembling and assembling rubber trays. Background Technology

[0002] A reel is a special type of wire reel, mainly used for winding and storing wires, cables, etc., and can also be used for winding carrier tape. It is widely used in the electronics, power, and communications industries. The reel assembly and disassembly structure refers to the mechanical structure used to achieve quick installation and disassembly of the reel. Its design purpose is to improve the efficiency of reel replacement and reduce labor intensity. Current reel installation mainly relies on bolt limiting (bolts connect and fix the reel to the installation part of the equipment) and fixed buckle limiting (fixed buckle structure is set on the reel or equipment installation part, usually made of elastic materials, such as plastic and metal spring sheets, etc.).

[0003] However, existing structures for disassembling and assembling rubber trays lack the ability to balance secure installation with ease of disassembly. Traditional rubber trays are basically limited by bolts or fasteners. Bolts provide a secure fixation, but disassembly is time-consuming and laborious. Fasteners are easier to install and remove than bolts, but since fasteners mainly rely on their own deformation to function, and rubber trays need to be disassembled and reassembled frequently, fasteners are prone to aging and breakage under stress. Utility Model Content

[0004] The purpose of this invention is to provide a structure for disassembling and assembling rubber discs to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A structure for disassembling and assembling a rubber tray includes a rubber tray body, a rotating shaft inserted inside the rubber tray body, a limiting plate abutting the top of the rubber tray body, a limiting cylinder fixedly connected to the center of the limiting plate, a receiving groove formed inside the limiting cylinder near the bottom, a return spring fixedly connected inside the receiving groove, a locking block fixedly connected to the end of the return spring away from the receiving groove, a limiting block fixedly connected to the center of the top of the rotating shaft, the locking block abutting against the limiting block, a pull rope fixedly connected to the side of the locking block away from the limiting block, and a pressing block fixedly connected to the end of the pull rope away from the locking block.

[0007] Preferably, the push block is inserted into the limiting cylinder, and a plurality of damping springs are fixedly connected to the bottom of the push block. A support ring is fixedly connected to the bottom end of the damping spring. The support ring and the limiting cylinder are fixedly connected. A plurality of grooves adapted to the pull rope are opened inside the limiting cylinder.

[0008] Preferably, a plurality of positioning blocks are inserted into the bottom of the rubber disc body, a positioning disk is fixedly connected to the bottom of the positioning blocks, the positioning disk abuts against the rubber disc body, and the positioning disk is fixedly connected to the rotating shaft, and a rolling component is fixedly connected to the bottom of the positioning disk.

[0009] Preferably, the rolling assembly includes a mounting ring, with a plurality of balls inserted inside the mounting ring. The bottom of each ball abuts against a frame mounting base, and the frame mounting base is engaged with the positioning disc.

[0010] Preferably, a first gripping strip is fixedly connected to the outer surface of the pressing block, and a second gripping strip is fixedly connected to the outer surface of the limiting cylinder.

[0011] Preferably, the cross-section of the limiting block is approximately U-shaped, and the locking block radiates from the side closest to the limiting block to the side furthest from the limiting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This is a structure for disassembling and assembling a rubber disc. Through the arrangement of a push block, a limiting cylinder, a pull rope, a locking block, a return spring, and a limiting block, in use, the user holds the upper and lower grips close together, inserts the push block into the limiting cylinder, causing the pull rope to slide, the locking block compresses the return spring and retracts into the receiving groove, and all four locking blocks are pulled out from the bottom of the limiting block. Holding the grips and lifting, the limiting cylinder, push block, and limiting disc are removed from the rotating shaft as a whole, releasing the top limiting of the rubber disc body. The rubber disc body is then removed upwards, completing the disassembly. During installation, the rubber disc body is aligned with the positioning block and inserted into the rotating shaft. Holding the second grip, the limiting cylinder is aligned with the limiting block and pressed downwards. The locking block and the limiting block slide relative to each other, squeezing the locking block into the receiving groove until the limiting disc abuts against the rubber disc body. Under the action of the return spring, the locking block pops out and locks into the bottom of the limiting block, completing the fixing of the limiting disc and limiting the installation of the rubber disc body. With this structure, disassembly and assembly are convenient and the fixing is secure.

[0014] 2. This is a structure for disassembling and assembling rubber discs. By setting up a rolling component, when in use, the rotating shaft is passively rotated by traction, which drives the bearing to rotate and causes the balls to roll inside the bearing. This reduces the friction at the bottom of the positioning disc, which is amplified by the weight of the rubber disc, and makes the rotation between the positioning disc and the frame mounting base smoother.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0022] A structure for disassembling and assembling a rubber tray includes a rubber tray body 1, a rotating shaft 2 inserted inside the rubber tray body 1, a limiting plate 3 abutting the top of the rubber tray body 1, a limiting cylinder 4 fixedly connected to the center of the limiting plate 3, a receiving groove 5 formed inside the limiting cylinder 4 near its bottom, a return spring 6 fixedly connected inside the receiving groove 5, a locking block 7 fixedly connected to the end of the return spring 6 away from the receiving groove 5, a limiting block 8 fixedly connected to the top center of the rotating shaft 2, the locking block 7 abutting against the limiting block 8, a pull rope 9 fixedly connected to the side of the locking block 7 away from the limiting block 8, a pressing block 10 fixedly connected to the end of the pull rope 9 away from the locking block 7. In use, pressing the pressing block 10 inserts it into the limiting cylinder 4, causing the bent pull rope 9 to slide with its top moving downwards and its tail moving upwards, causing the locking block 7 to compress the return spring 6 and retract into the receiving groove 5. All four locking blocks 7 are then pulled out from the bottom of the limiting block 8. Holding the two grips and lifting, the limiting cylinder 4, the pressing block 10, and the limiting plate 3 are disassembled. The entire assembly is removed from the rotating shaft 2, releasing the top limit on the rubber disc body 1. Then, the rubber disc body 1 can be removed upwards to complete the disassembly. During installation, the rubber disc body 1 is inserted into the rotating shaft 2. Hold the grip bar 21, align the limiting cylinder 4 with the limiting block 8 and press down. The lower inclined surface of the locking block 7 and the upper inclined surface of the limiting block 8 slide relative to each other, squeezing the locking block 7 into the receiving groove 5 until the limiting disc 3 abuts against the rubber disc body 1. Under the action of the return spring 6, the locking block 7 pops out and locks into the bottom of the limiting block 8, completing the fixation of the limiting disc 3 and limiting the rubber disc body 1, thus completing the installation. With the above structure, disassembly and assembly are convenient and the fixation is firm. Among them, a small part of the push block 10 is inserted into the small tube, and its bottom is fixed to the four pull ropes 9. The pull ropes 9 pass through the groove 13 and are then fixed to the locking block 7. Since the bending path of the pull rope 9 is close to the lying U-shape, when the upper end moves down, the lower end is pulled and slides in the groove 13, causing the locking block 7 to slide in the receiving groove 5.

[0023] In this embodiment, preferably, the button 10 is inserted into the limiting cylinder 4. Several damping springs 11 are fixedly connected to the bottom of the button 10. A support ring 12 is fixedly connected to the bottom end of the damping spring 11. The support ring 12 and the limiting cylinder 4 are fixedly connected. Several grooves 13 adapted to the pull rope 9 are opened inside the limiting cylinder 4. When in use, the button 10 is pressed and inserted into the limiting cylinder 4. The damping springs 11 are compressed, which drives the pull rope 9 to slide, so that the locking block 7 compresses the reset spring 6 and retracts into the receiving groove 5. All four locking blocks 7 are pulled out from the bottom of the limiting block 8. The limiting cylinder 4, the button 10 and the limiting disc 3 are removed from the rotating shaft 2 as a whole, and the top of the rubber disc body 1 is released from the limitation. When the button 10 is pressed, the damping spring 11 is compressed and the reset spring 6 is also compressed. When the pressing is stopped, the button 10 returns to its position under the action of the damping spring 11 and the reset spring 6. The pull rope 9 and the locking block 7 return to their positions without pressing the button 10, which facilitates the next repeated disassembly and assembly operation.

[0024] In this embodiment, preferably, a plurality of positioning blocks 14 are inserted into the bottom of the rubber disc body 1, and a positioning disk 15 is fixedly connected to the bottom of the positioning blocks 14. The positioning disk 15 abuts against the rubber disc body 1 and is fixedly connected to the rotating shaft 2. A rolling component 16 is fixedly connected to the bottom of the positioning disk 15. In use, the rubber disc body 1 is inserted into the rotating shaft 2 and then inserted into the positioning blocks 14 to initially fix the rubber disc body 1. Subsequently, the rubber disc body 1 is limited by the push block 10, the limiting cylinder 4 and the limiting disk 3 to complete the installation. The bottom of the rubber disc body 1 needs to have a circular groove that matches the positioning block 14, and the depth is less than the thickness of the disc-shaped component at the bottom of the rubber disc body 1. This is prior art and will not be explained in detail.

[0025] In this embodiment, preferably, the rolling assembly 16 includes a mounting ring 17, with a plurality of balls 18 inserted inside the mounting ring 17. The bottom of the balls 18 abuts against a frame mounting base 19, which is engaged with the positioning disc 15. In use, the rotating shaft 2 is passively rotated by traction, causing the bearing to rotate and the balls 18 to roll inside the bearing, reducing the friction at the bottom of the positioning disc 15 amplified by the weight of the disc, making the rotation between the positioning disc 15 and the frame mounting base 19 smoother. The positioning disc 15 has a convex cross-section, and the frame mounting base 19 has a groove adapted to the positioning disc 15 and the ball 18 assembly. The groove also has a convex cross-section, and the overall depth of the groove is equal to the overall thickness of the positioning disc 15 and the ball 18 assembly after installation. The frame mounting base 19 is a basic support plate component on the equipment frame in the prior art used to support and position the disc system, and will not be explained in detail here.

[0026] In this embodiment, preferably, a grip strip 20 is fixedly connected to the outer surface of the press block 10, and a grip strip 21 is fixedly connected to the outer surface of the limiting cylinder 4. During use, both grip strips are simultaneously gripped and pressed together, the press block 10 is inserted into the limiting cylinder 4, causing the locking block 7 to compress the reset spring 6 and retract into the receiving groove 5. The limiting cylinder 4, press block 10, and limiting disc 3 are then removed from the rotating shaft 2, releasing the restriction on the top of the rubber disc body 1. The grip strips 20 and 21 are symmetrically arranged in pairs and correspond vertically. To facilitate workers applying force with both hands, when installing the limiting disc 3, the limiting cylinder 4 can be pressed separately. By pressing, the inclined surfaces of the locking block 7 and the limiting block 8 will contact and slide relative to each other, thereby locking the locking block 7 into the limiting block 8 to complete the installation. Alternatively, the upper and lower grips can be clamped together with both hands to bring the locking block 7 into the receiving groove 5 in advance. After placing the limiting disc 3, the grips can be released to lock the locking block 7 into the limiting block 8 to complete the installation. Alternatively, the pressing block 10 can be pressed directly to partially retract the locking block 7 into the receiving groove 5. As the pressing force continues to be applied, the locking block 7 and the limiting block 8 will slide relative to each other and continue to retract into the receiving groove 5. Then, under the action of the return spring 6, the locking block 7 will lock the limiting block 8. The specific operation method depends on the actual situation. Direct pressing is more labor-saving and easier to operate.

[0027] In this embodiment, preferably, the cross-section of the limiting block 8 is approximately U-shaped, and the locking blocks 7 are radially arranged from the side closest to the limiting block 8 to the side furthest from the limiting block 8. During use, as the limiting cylinder 4 is pressed, the bottom inclined surface of the locking block 7 contacts the top inclined surface of the limiting block 8. Continued pressing causes the two inclined surfaces to slide relative to each other. Since the position of the limiting block 8 is fixed, the four locking blocks 7 are respectively fixed to the four receiving grooves 5 by the return springs 6, allowing them to move. Therefore, the locking blocks 7 slide into the receiving grooves 5 until the bottom of the limiting plate 3 meets the body of the rubber plate. 1. The top abutment, the top plane of the locking block 7 and the bottom plane of the conical frustum of the limiting block 8 are on the same horizontal plane, the limiting block 8 no longer presses the locking block 7, and under the action of the return spring 6, the locking block 7 is locked into the bottom of the limiting block 8, avoiding relative movement between the limiting cylinder 4 and the limiting block 8, thereby preventing relative movement between the surface limiting disk 3 and the rotating shaft 2, and thus axially restricting the rubber disk body 1; wherein, the limiting block 8 is composed of a top conical frustum and a bottom cylindrical part, the locking block 7 is locked at the bottom of the conical frustum and abuts against the surface of the cylindrical part.

[0028] Working principle: In this embodiment, the structure for disassembling and assembling a rubber tray is used by simultaneously gripping the two handles with both hands and squeezing them together. The push block 10 is inserted into the limiting cylinder 4, causing the bent pull rope 9 to slide with the top moving downward and the tail moving upward. This causes the locking block 7 to compress the reset spring 6 and retract into the receiving groove 5. All four locking blocks 7 are pulled out from the bottom of the limiting block 8. Lifting up, the limiting cylinder 4, push block 10, and limiting plate 3 are removed from the rotating shaft 2 as a whole, releasing the limitation on the top of the rubber tray body 1. Then, it is lifted upward. Disassembly is completed by removing the main body 1 of the rubber disc. During installation, the main body 1 of the rubber disc is aligned with the positioning block 14 and inserted into the rotating shaft 2. The limiting cylinder 4 is aligned with the limiting block 8 and pressed down. The lower inclined surface of the locking block 7 and the upper inclined surface of the limiting block 8 slide relative to each other, squeezing the locking block 7 into the receiving groove 5 until the limiting plate 3 abuts against the main body 1 of the rubber disc. Under the action of the return spring 6, the locking block 7 pops out and locks into the bottom of the limiting block 8, completing the fixation of the limiting plate 3 and limiting the rubber disc 1, thus completing the installation. With the above structure, disassembly and assembly are convenient and the fixation is firm.
