Description

Technical Field

[0001] The utility model relates to the technical field of crab binding, in particular to a device for assisting crab binding. Background Art

[0002] Crabs are a household delicacy because of their rich nutrition and delicious taste. In order to facilitate the transportation of crabs and improve the survival rate and safety, almost all sellers will use the cross-binding method to bundle crabs, or use crab quick-packing boxes to pack crabs. Using quick-packing boxes to pack crabs also requires manual packaging costs, and the cost of the quick-packing boxes themselves is also relatively high, which is not suitable for small companies.

[0003] In small companies, most of them use manual cross-binding of crabs. In the process of tying crabs, one hand is required to hold the crab tightly and the other hand to take the rope to tie the crab. This is not only cumbersome, but also there is a risk of being injured by the crab. Utility Model Content

[0024] The side wall of the arc-shaped plate 103 is fixedly connected with an elastic component 2, the end of the elastic component 2 is fixedly connected with a fixed block 201, and a square pit 202 is provided on the surface of the fixed block 201, the top of the bottom plate 1 is fixedly connected with a top plate 203, the top of the top plate 203 is fixedly connected with a first connecting plate 204, the side wall of the first connecting plate 204 is rotatably connected with a connecting column 205, and the outer wall of the connecting column 205 is provided with a rope body 206;

[0025] The inner walls of both sides of the top plate 203 below the rope body 206 are slidably connected with sliding blocks 207, and a first spring 208 is fixedly connected between the sliding block 207 and the inner wall of the top plate 203;

[0026] There are four sets of arc plates 103 and fixed blocks 201, and they are symmetrical about the central axis of the rotating disk 102;

[0027] It should be noted that: the crab to be tied is placed in the inner cavity of the square pit 202 set in the fixed block 201, and the elastic force of the elastic component 2 is used to drive the fixed block 201 to move closer to the middle, so as to fix the crab, and then the rope body 206 is pulled, and the rope body 206 passes through the middle of the sliding block 207, and the elastic force of the first spring 208 is used to drive the sliding block 207 to move closer to the middle, clamping the rope body 206 in the middle to prevent the rope body 206 from shaking, which is not conducive to subsequent bundling, and then the rope body 206 is pulled to tie one side of the crab, and then the turntable 102 is rotated by the rotating column 101 to tie the other side of the crab. In the above, the fixed block 201 is used to fix the crab first, and then the rope body 206 is used to tie the crab. There is no need for the staff to directly hold the crab by hand for tying, thereby avoiding the risk of being injured by the crab.

[0028] Reference Figure 1-4 The bottom of the top plate 203 is fixedly connected with the second connecting plate 3, and the side wall of the second connecting plate 3 is slidably connected with the first sliding column 301;

[0029] A cutter 302 is fixedly connected to the end of the first sliding column 301 located on the inner side of the second connecting plate 3, and a second spring 303 is fixedly connected between the first sliding column 301 and the second connecting plate 3;

[0030] The elastic component 2 includes a sleeve 304, a second sliding column 305 and a third spring 306. The sleeve 304 is fixedly mounted on the side wall of the arc plate 103. The second sliding column 305 is slidably connected to the inner wall of the sleeve 304. The second sliding column 305 is fixedly connected to the fixed block 201. The third spring 306 is fixedly connected between the second sliding column 305 and the sleeve 304.

[0031] It should be noted that after the crab is tied up, the first sliding column 301 is pressed toward the rope body 206. At this time, the first sliding column 301 will drive the cutter 302 to move toward the rope body 206, and the second spring 303 will be compressed to generate a rebound force. After the cutter 302 cuts the rope body 206, the first sliding column 301 is released. Under the rebound force of the second spring 303, the first sliding column 301 drives the cutter 302 to return to its original position, which is convenient for cutting the rope body 206. The third spring 306 drives the second sliding column 305 to move toward the outside of the sleeve 304, and drives the fixed block 201 at its end to slide, thereby clamping the crab in the inner cavity of the fixed block 201.

[0032] Reference Figure 1-4 The side wall of the bottom plate 1 is fixedly connected with a side plate 307, and the side wall of the side plate 307 is slidably connected with a third sliding column 308;

[0033] A locking hole 309 is formed on the side wall of the rotating column 101, and the third sliding column 308 can extend into the inner cavity of the locking hole 309. A fourth spring 310 is fixedly connected between the third sliding column 308 and the side plate 307.

[0034] It should be noted that: when it is necessary to rotate the turntable 102, the third sliding column 308 is stretched outward, at this time the fourth spring 310 is stretched to generate a rebound force, the third sliding column 308 slides to the outside of the clamping hole 309 opened on the side wall of the rotating column 101, and then the turntable 102 is rotated to adjust the binding position of the crab. After the adjustment is completed, the third sliding column 308 is released. Under the rebound force of the fourth spring 310, the third sliding column 308 slides to its original position and extends to the inner cavity of the clamping hole 309 opened on the side wall of the rotating column 101, completing the clamping, which is convenient for bundling crabs.

[0035] Operation method: Place the crab to be tied up in the inner cavity of the square pit 202 set in the fixed block 201, and use the elastic force of the third spring 306 to drive the second sliding column 305 to move to the outside of the sleeve 304, and drive the fixed block 201 at its end to slide, so as to clamp the crab in the inner cavity of the fixed block 201, and then pull the rope 206, and the rope 206 passes through the middle of the sliding block 207. Use the elastic force of the first spring 208 to drive the sliding block 207 to move closer to the middle, clamping the rope 206 in the middle to prevent the rope 206 from shaking, which is not conducive to subsequent tying The third sliding post 308 is stretched outward, and the fourth spring 310 is stretched to generate a rebound force, and the third sliding post 308 slides to the outside of the clamping hole 309 opened on the side wall of the rotating post 101. The rotating disk 102 is rotated to adjust the binding position of the crab. After the adjustment is completed, the third sliding post 308 is released. Under the rebound force of the fourth spring 310, the third sliding post 308 slides to the original position and extends to the inner cavity of the clamping hole 309 opened on the side wall of the rotating post 101. The clamping is completed, which is convenient for binding the other side of the crab.

[0036] After the crab is tied up, the first sliding column 301 is pressed in the direction of the rope body 206. At this time, the first sliding column 301 will drive the cutter 302 to move in the direction of the rope body 206, and the second spring 303 will be compressed to generate a rebound force. After the cutter 302 cuts the rope body 206, the first sliding column 301 is released. Under the rebound force of the second spring 303, the first sliding column 301 drives the cutter 302 to return to its original position, which is convenient for cutting the rope body 206. The above completes the tying of the crab, and the staff does not need to directly hold the crab by hand to tie it up, avoiding the risk of being injured by the crab.
