Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of sprocket storage devices, and in particular relates to a sprocket suspension bracket. Background Technology
[0002] A sprocket, or chain wheel with interlocking teeth, is used in bicycle manufacturing. When workers grind and finish sprockets, many sprockets need to be simultaneously moved to the grinding position via a suspension bracket. A search revealed a patent application (application number 201822161728.9) disclosing a suspension bracket for sprocket production, comprising a base and a sprocket isolation mechanism. A counterweight is mounted on the upper side of the base, and a suspension bracket body is fixedly mounted on the upper side of the counterweight. Sprocket hangers are welded to both sides of the suspension bracket body, and the hangers are perpendicular to the bracket body. Multiple sprockets pass through the hangers via the sprocket isolation mechanism. The base has an inverted concave cross-section.
[0003] However, in actual use, the applicant found that when limiting the sprockets attached to the sprocket hangers, multiple end fixing nuts were used to limit multiple sprocket hangers one by one. When it was necessary to release the sprockets, multiple fixing nuts had to be unscrewed from the sprocket hangers one by one, which was not convenient to operate. Therefore, we propose a sprocket suspension bracket. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model relates to a sprocket suspension bracket, comprising a base, a support fixedly mounted on the top of the base, sprocket suspension rods fixedly connected in a rectangular array on both sides of the support, a top plate above the support, a connecting plate at the bottom of the top plate, a screw rotatably connected to the inside of the support via a bearing, the thread of the screw penetrating the connecting plate, a first bevel gear sleeved and fixed at the lower end of the screw, a rotating rod rotatably connected to the inside of the base via a bearing, a second bevel gear sleeved and fixed at one end of the rotating rod, the second bevel gear being drively connected to the first bevel gear, one end of the rotating rod extending to the outside of the base and sleeved and fixedly mounted on an adjusting disc, limit stops fixedly connected at equal intervals at the bottom of the top plates on both sides of the support, columns fixedly connected at the four corners of the bottom of the top plates, and storage slots provided at the four corners of the bottom of the base, with connecting seats movably mounted inside the storage slots, and wheels fixedly mounted at the bottom of the connecting seats.
[0006] Preferably, the upper part of the connecting seat extends to the outside of the base and is provided with a limiting circular plate.
[0007] Preferably, the four columns are located directly above the four connecting seats.
[0008] Preferably, guide rods are fixedly provided at the bottom of both ends of the top plate, and the lower ends of the two guide rods are fixedly connected by a connecting plate.
[0009] Preferably, the connecting plate slides along the inner wall of the stand, the upper end of the screw is rotatably connected to the stand through a bearing, and the lower end of the screw is rotatably connected to the base through a bearing.
[0010] Preferably, the limiting stop bar has a clearance groove for avoiding the sprocket suspension rod.
[0011] This utility model has the following beneficial effects:
[0012] This utility model discloses a sprocket suspension bracket. By driving the screw to rotate, the top plate and the limiting stop bar move downwards. The limiting stop bar can limit the sprocket suspended on the sprocket suspension rod, preventing the sprocket from slipping off the sprocket suspension rod during movement. This eliminates the need to use multiple nuts to limit the sprockets suspended on the sprocket suspension rod one by one, making it more convenient. During the process of limiting the sprockets suspended on the sprocket suspension rod, the column can press the connecting seat, causing the traveling wheel to move out of the storage slot and lifting the bottom of the base off the ground, making it easier for personnel to move the sprocket suspension bracket. When the driving limiting stop bar moves upwards to release the sprocket, the column moves upwards simultaneously, allowing the traveling wheel to gradually move into the storage slot, so that the bottom of the base contacts the ground, thereby ensuring the sprocket suspension bracket is placed stably and has a better performance.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 As shown, this utility model provides a technical solution:
[0022] A sprocket suspension bracket includes a base 1, a support 2 fixedly mounted on the top of the base 1, sprocket suspension rods 5 fixedly connected in a rectangular array on both sides of the support 2, a top plate 3 above the support 2, a connecting plate 32 at the bottom of the top plate 3, guide rods 31 fixedly mounted at the bottom of both ends of the top plate 3, the lower ends of the two guide rods 31 being fixedly connected by the connecting plate 32, the connecting plate 32 sliding along the inner side wall of the support 2, a screw 9 rotatably connected to the inside of the support 2 via a bearing, the thread of the screw 9 penetrating the connecting plate 32, the upper end of the screw 9 rotatably connected to the support 2 via a bearing, and the lower end of the screw 9 rotatably connected to the base 1 via a bearing, a first bevel gear 91 sleeved and fixed to the lower end of the screw 9, and a rotating rod 10 rotatably connected to the inside of the base 1 via a bearing, one end of the rotating rod 10 sleeved and fixed with a second bevel gear. The first bevel gear 91 is connected to the second bevel gear 101. One end of the rotating rod 10 extends to the outside of the base 1 and is fitted with an adjusting disc 102. Limiting stops 4 are fixedly connected at equal intervals to the bottom of the top plates 3 on both sides of the stand 2. The limiting stops 4 are used to limit the sprockets suspended on the sprocket suspension rod 5 to prevent the sprockets from slipping off the sprocket suspension rod 5. The limiting stops 4 are provided with clearance grooves 41 to avoid the sprocket suspension rod 5. By rotating the drive screw 9, the top plate 3 and the limiting stops 4 move downward. The limiting stops 4 can limit the sprockets suspended on the sprocket suspension rod 5 to prevent the sprockets from slipping off the sprocket suspension rod 5 during the movement. It is more convenient than using multiple nuts to limit the sprockets suspended on the sprocket suspension rod 5 one by one.
[0023] Each of the four corners of the bottom of the top plate 3 is fixedly connected with a column 6, and each of the four corners of the bottom of the base 1 is provided with a storage slot 11. A connecting seat 7 is movably installed inside the storage slot 11. The connecting seat 7 can move up and down. A traveling wheel 8 is fixedly installed at the bottom of the connecting seat 7. The upper part of the connecting seat 7 extends to the outside of the base 1 and is provided with a limiting circular plate. The four columns 6 are located directly above the four connecting seats 7. During the process of limiting the sprocket suspended on the sprocket suspension rod 5, the columns 6 can squeeze the connecting seat 7, causing the traveling wheel 8 to move out of the storage slot 11 and lifting the bottom of the base 1 off the ground. This makes it easier for personnel to move the sprocket suspension bracket. During the process of driving the limiting stop bar 4 to move upward to release the sprocket, the columns 6 move upward simultaneously, allowing the traveling wheel 8 to gradually move into the storage slot 11, so that the bottom of the base 1 contacts the ground. This allows the sprocket suspension bracket to be placed stably and has a better performance.
[0024] Working principle: In use, a suitable number of sprockets can be suspended one by one on each sprocket suspension rod 5. The adjusting disc 102 is manually rotated clockwise to drive the rotating rod 10 to rotate. The rotation of the rotating rod 10 drives the second bevel gear 101 to rotate. The rotation of the second bevel gear 101 drives the first bevel gear 91 and the screw 9 to rotate. The rotation of the screw 9 drives the connecting plate 32, the guide rod 31 and the top plate 3 to move downward together. At this time, the downward movement of the top plate 3 drives the limiting stop 4 to move downward, so that the limiting stop 4 moves to the front end of the sprocket suspension rod 5. The limiting stop 4 can limit the sprockets suspended on the sprocket suspension rod 5. At the same time, the top plate 3 moves downward. The downward movement of plate 3 can drive column 6 to move downward, and column 6 can press down on connecting seat 7. At this time, base 1 can move upward and lift off the ground, so that the sprocket suspension bracket can be moved by the traveling wheel 8. When it is necessary to release the sprocket, manually turn the adjusting plate 102 counterclockwise, which can drive the top plate 3 together with the limit stop 4 and column 6 to move upward. At this time, the limit stop 4 moves away from the front end of the sprocket suspension rod 5 to release the sprocket. After the connecting seat 7 gradually loses the pressure of column 6, it can drive the traveling wheel 8 to move into the storage groove 11, so that the bottom of base 1 contacts the ground, and the sprocket suspension bracket can be placed stably.
