Description

Technical Field

[0001] The utility model relates to the technical field of mining connectors, in particular to an adjustable mining connecting ring. Background Art

[0002] Mining connecting rings are a widely used connector in the mining industry and play a vital role. They are a connecting and fixing tool, usually made of high-strength steel or alloys such as steel, stainless steel and tin-plated aluminum alloy. They have the characteristics of strong load-bearing capacity and long service life. The main function of mining connecting rings is to connect and fix heavy equipment such as mine hoists, mine conveyors, mine elevators, as well as pipelines, rock drills, blasting equipment, winches, thumb levers and other various electrical equipment and box supports. In heavy industrial fields such as mines and quarries, the quality and reliability of mining connecting rings directly affect the safety and efficiency of the entire production process.

[0003] The existing Chinese patent with announcement number CN220523187U discloses a chain connecting ring for mining that is easy to disassemble, including a quick-release lock buckle. The quick-release lock buckle includes a connecting ring body, the outer surface of the connecting ring body is provided with a movable groove, and two pin shafts are rotatably connected between the inner walls of the movable groove. The outer surfaces of the two pin shafts are fixed with locking blocks, and the opposite sides of the two locking blocks are provided with a clamping groove. The two clamping grooves are clamped with each other, and the ends of the two locking blocks away from the clamping grooves are hook claws, and the sides of the two locking blocks close to the clamping grooves are both inclined surfaces.

[0004] Although the above solution can be quickly disassembled, in the complex and changeable environment of mining operations, there are many types of equipment with different specifications. The length of the connecting ring is fixed and cannot be adjusted. Due to the limitation of fixed length, these connecting rings often cannot adapt well to equipment components of different sizes and shapes, resulting in poor connection effect. Therefore, it does not meet existing needs. In this regard, we propose an adjustable mining connecting ring. Utility Model Content

[0005] The purpose of the utility model is to provide an adjustable mining connecting ring to solve the problem in the background art that the length of the mining connecting ring is fixed and cannot be adjusted, resulting in the inability to adapt well to equipment components of different sizes and shapes.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an adjustable mining connecting ring, comprising two connecting rings, one end of which is provided with an adjustment seat;

[0007] The first transmission chamber is provided inside the adjustment seat, a double-threaded transmission rod is rotatably provided on one side of the first transmission chamber, and a movable plate is threadedly connected to the upper and lower sides of the outer portion of the double-threaded transmission rod, and a plurality of equally spaced limit blocks are welded to the inner side of the movable plate, one end of each limit block passes through and extends to the outside of the first transmission chamber, and each limit block is slidably engaged with the first transmission chamber;

[0008] It also includes a second transmission cavity, which is opened on one side of the adjustment seat. A rotating shaft is arranged inside the second transmission cavity. One end of the rotating shaft passes through and extends into the interior of the first transmission cavity, and the end of the rotating shaft located inside the first transmission cavity is fixedly connected to the double-threaded transmission rod.

[0009] Preferably, a transmission worm is rotatably provided at the rear side of the second transmission cavity, and worm transmission is performed between the transmission worm and the transmission worm wheel.

[0010] Preferably, a rotating rod is welded to one end of the transmission worm, and one end of the rotating rod passes through and extends to the outside of the second transmission cavity, and the rotating rod is rotatably matched with the second transmission cavity, and a knob is installed at one end of the rotating rod located outside the second transmission cavity.

[0011] Preferably, a protective sliding cover is provided on the outer wall of the adjustment seat, and the protective sliding cover is in sliding cooperation with the adjustment seat.

[0012] Preferably, two spring seats are provided on one side of the protective sliding cover, and the spring seats are both adhered and fixed to the adjustment seat. Two sliding cavities are opened on one side of the interior of the protective sliding cover, and the sliding cavities and the spring seats are slidably matched. A spring is provided inside the spring seat, one end of the spring is connected to the spring seat, and the other end of the spring is connected to the sliding cavity.

[0013] Preferably, guide rods are welded to the upper and lower sides of one side inside the first transmission cavity, and the guide rods pass through the movable plate, and the guide rods are slidably engaged with the movable plate.

[0014] Preferably, a plurality of equally spaced limiting grooves are provided on the upper and lower sides of one end of the connecting ring, and the limiting grooves are adapted to one end of the limiting block located outside the first transmission cavity.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model provides an adjusting seat at one end of the connecting ring, and one end of the other connecting ring is inserted into the adjusting seat. By rotating the double-threaded transmission rod, the two movable plates can be moved toward each other, and then the limit blocks can be driven to insert into the limit grooves on the upper and lower sides of one end of the connecting ring, so that the two adjusting seats can be quickly docked. By controlling the distance at which the connecting ring is inserted into the adjusting seat, the overall length of the connecting ring can be adjusted. By adjusting the overall length of the connecting ring, it can well adapt to equipment components of different sizes and shapes, greatly improving the flexibility and versatility of the connection, and the best installation effect can be achieved through simple adjustment.

[0017] 2. The utility model opens a second transmission cavity on one side of the adjusting seat. When the operator needs to rotate the double-threaded transmission rod, he only needs to turn the knob, and the knob will rotate the transmission worm. Since the transmission worm wheel and the transmission worm are driven by a worm, the transmission worm wheel will drive the rotating shaft to rotate synchronously, and the rotating shaft will drive the double-threaded transmission rod to rotate. Since the worm drive has self-locking properties, when the knob is stopped, the double-threaded transmission rod itself will not rotate, thereby ensuring that the limit block is not easy to disengage after being stuck in the limit groove, thereby improving the firmness during use.

[0018] 3. The utility model provides a protective sliding cover on one side of the adjustment outer wall. When the knob is turned, the protective sliding cover will slide toward the knob under the elastic action of the spring. The protective sliding cover can shield the knob, thereby avoiding accidents that may cause accidental touching of the knob during use, further ensuring the stability after connection, simple operation, and easy to use.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-5 The utility model provides a technical solution: an adjustable mining connecting ring, comprising a connecting ring 1, wherein two connecting rings 1 are provided, and an adjusting seat 2 is provided at one end of the connecting ring 1;

[0027] It also includes a first transmission chamber 3, which is opened inside the adjustment seat 2. A double-threaded transmission rod 4 is rotatably provided on one side of the first transmission chamber 3. The upper and lower sides of the outer side of the double-threaded transmission rod 4 are threadedly connected to a movable plate 5. A plurality of equally spaced limit blocks 7 are welded to the inner side of the movable plate 5. One end of the limit block 7 passes through and extends to the outside of the first transmission chamber 3, and the limit blocks 7 are all slidably engaged with the first transmission chamber 3.

[0028] It also includes a second transmission chamber 10, which is opened on one side of the adjustment seat 2. A rotating shaft 9 is rotatably arranged inside the second transmission chamber 10. One end of the rotating shaft 9 passes through and extends to the inside of the first transmission chamber 3, and the end of the rotating shaft 9 located inside the first transmission chamber 3 is fixedly connected to the double-threaded transmission rod 4.

[0029] When in use, the two connecting rings 1 are docked, and one end of the connecting ring 1 is inserted into the interior of the adjusting seat 2, and then the protective sliding cover 14 is pulled to slide the spring seat 16 into the sliding cavity 15, and then the knob 13 is turned to drive the transmission worm 18 to rotate in the first transmission cavity 3 through the rotating rod 12. Due to the worm transmission between the transmission worm 18 and the transmission worm gear 11 located in the second transmission cavity 10, the transmission worm gear 11 will drive the rotating shaft 9 and the double-threaded transmission rod 4 to rotate. The rotation of the double-threaded transmission rod 4 causes the two movable plates 5 to move in opposite or opposite horizontal straight lines under the limit of the guide rod 6, and to be inserted into the limit groove 8 through the limit block 7 to achieve clamping and fixation of the connecting ring 1. By adjusting the overall length of the connecting ring 1, it can well adapt to equipment components of different sizes and shapes.

[0030] See also Figure 3 and Figure 4 A transmission worm 18 is provided at the rear side of the second transmission cavity 10, and a worm transmission is performed between the transmission worm 18 and the transmission worm wheel 11. The transmission worm 18 can stably drive the transmission worm wheel 11 to rotate, thereby achieving precise torque transmission and speed adjustment. At the same time, the worm transmission has a self-locking function, which effectively prevents accidental loosening after adjustment.

[0031] See also Figure 3 and Figure 4 , one end of the transmission worm 18 is welded with a rotating rod 12, one end of the rotating rod 12 passes through and extends to the outside of the second transmission cavity 10, and the rotating rod 12 rotates with the second transmission cavity 10. A knob 13 is installed at one end of the rotating rod 12 located outside the second transmission cavity 10. The rotating rod 12 can be easily operated by the knob 13, thereby driving the transmission worm 18 to rotate, thereby realizing rapid adjustment of the length of the connecting ring, and the operation is simple and intuitive;

[0032] See also Figure 1 、 Figure 3 and Figure 4 The outer wall of the adjustment seat 2 is provided with a protective sliding cover 14, and the protective sliding cover 14 is slidably matched with the adjustment seat 2. The protective sliding cover 14 can effectively block the knob 13 to prevent misoperation, thereby improving the safety and reliability of the equipment;

[0033] See also Figure 1 、 Figure 3 and Figure 5 , two spring seats 16 are provided on one side of the protective sliding cover 14, and the spring seats 16 are both adhered and fixed to the adjustment seat 2, two sliding cavities 15 are opened on one side of the interior of the protective sliding cover 14, and the sliding cavity 15 and the spring seat 16 are slidably matched, and a spring 17 is provided inside the spring seat 16, one end of the spring 17 is connected to the spring seat 16, and the other end of the spring 17 is connected to the sliding cavity 15, and the spring 17 can provide continuous elastic force, so that the protective sliding cover 14 is automatically reset when not subject to external force, ensuring that the knob 13 is always in a protected state;

[0034] See also Figure 4 Guide rods 6 are welded on the upper and lower sides of one side inside the first transmission cavity 3. The guide rods 6 pass through the movable plate 5 and slide with the movable plate 5. The guide rods 6 can ensure that the movable plate 5 moves stably in the horizontal direction, avoiding deviation and shaking during the movement, and improving the adjustment accuracy and stability.

[0035] See also Figure 4A number of equally spaced limit grooves 8 are provided on the upper and lower sides of one end of the connecting ring 1, and the limit groove 8 is adapted to the end of the limit block 7 located outside the first transmission cavity 3. The limit block 7 can be accurately inserted into the limit groove 8 to achieve a firm fixation of the connecting ring 1. At the same time, multiple equally spaced limit grooves 8 provide a variety of adjustment positions to meet the connection requirements of equipment components of different sizes and shapes.

[0036] Working principle: When in use, when the two connecting rings 1 are docked, one end of the connecting ring 1 is inserted into the inside of the adjusting seat 2. After one end of the connecting ring 1 moves into the adjusting seat 2, first pull the protective sliding cover 14 to make the spring seat 16 slide into the inside of the sliding cavity 15. At this time, the spring 17 will be compressed, and then turn the knob 13. The knob 13 will drive the rotating rod 12 to rotate synchronously, and the rotating rod 12 will drive the transmission worm 18 to rotate. Due to the worm transmission between the transmission worm 18 and the transmission worm gear 11, the transmission worm gear 11 will drive the rotating shaft 9 to rotate synchronously, and the rotating shaft 9 will drive the double-threaded transmission rod 4 to rotate. The double-threaded transmission rod 4 will drive the two movable plates 5 to rotate synchronously. Since one end of the movable plate 5 slides with the guide rod 6, the movable plates 5 will be subject to axial limitation, and the rotation of the two movable plates 5 will be converted into horizontal straight lines in opposite directions. When the lever 1 is in the unlocked position, the movable plate 5 drives the limit block 7 to move synchronously, and the limit block 7 is stuck in the limit groove 8, so that the end of the connecting ring 1 that is stuck in the adjusting seat 2 can be clamped and fixed. The operator can adjust the length of the connecting ring 1 after connection and assembly by controlling the distance at which the connecting ring 1 is stuck, which can well adapt to equipment components of different sizes and shapes. When the adjustment is completed, due to the worm transmission between the transmission worm 18 and the transmission worm wheel 11, the stability of the double-threaded transmission rod 4 after adjustment is guaranteed, and the limit block 7 is prevented from being led out of the limit groove 8. At the same time, when the protective slide cover 14 is loosened, under the elastic action of the spring 17, the protective slide cover 14 will move toward the direction of the limit knob 13, thereby protecting the knob 13 and avoiding accidental touching of the knob 13, thereby further ensuring the stability after connection.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
