[0018] 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 scope of protection of the present utility model.

[0019] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail. This application discloses a retractable conveyor roller. (Refer to...) Figures 1-5A retractable conveying roller includes a first roller 1, a second roller 11 slidably contacting the side wall of the first roller 1, a limit block 12 fixedly connected to the inner side wall of the second roller 11, a plurality of positioning holes 13 formed at the bottom of the inner side wall of the second roller 11, a support platform 14 fixedly connected to the side wall of the first roller 1, a support frame 15 fixedly connected to the top of the outer side wall of the support platform 14, a first spring 16 fixedly connected to the top of the outer side wall of the first spring 16, a first connecting plate 17 fixedly connected to the top of the outer side wall of the first connecting plate 17, a positioning pin 18 fixedly connected to the support platform 14, the positioning pin 18 contacting the positioning holes 13, a second spring 19 fixedly connected to the top of the outer side wall of the first connecting plate 17, a support frame 15 fixedly connected to the top of the outer side wall of the second spring 19, a hanging ring 10 fixedly connected to the outer side wall of the first connecting plate 17, and a groove 101 formed on the outer side wall of the second roller 11, the groove 101 being positioned above the first connecting plate 17.

[0020] Before the equipment starts working, the first roller 1 and the second roller 11 are installed in their respective positions. An external hook is inserted through the slot 101 and contacts the hanging ring 10. At this time, the hanging ring 10 is pulled, causing the first connecting plate 17 to move. The positioning pin 18 will then disengage from the positioning hole 13, pulling the second roller 11 to the other side. When the second roller 11 and the first roller 1 are separated to a suitable position, the tension applied to the hanging ring 10 is released, and the position of the positioning hole 13 is adjusted. The second spring 19 will push the first connecting plate 17, and the first spring 16 will pull the first connecting plate 17, thereby causing the positioning pin 18 to re-enter the positioning hole 13. Under the restriction of the limiting block 12 and the support platform 14, when the first roller 1 rotates, the second roller 11 will rotate accordingly. The support platform 14 and the positioning pin 18 can extend the overall length of the equipment, allowing it to adapt to different working scenarios and making it easier for staff to adjust the equipment according to the actual situation, thus reducing the difficulty of changing the equipment.

[0021] Reference Figure 5 and Figure 6 The positioning pin 18 has a second connecting plate 2 fixedly connected to its side wall. The second connecting plate 2 contacts the support platform 14. The inner side wall of the second connecting plate 2 contacts a fixing post 21. The top of the outer side wall of the first connecting plate 17 has a third spring 22 fixedly connected to it. The top of the outer side wall of the third spring 22 has a connecting disc 23 fixedly connected to it. The connecting disc 23 is located below the fixing post 21. The bottom of the outer side wall of the fixing post 21 has a threaded post 24 fixedly connected to it. The second connecting plate 2 is threadedly connected to the fixing post 21 through the threaded post 24. The threaded post 24 is threadedly connected to the support platform 14.

[0022] After the equipment is adjusted, the operator can use a screwdriver to contact the fixing post 21 and press it down until the threaded post 24 contacts the second connecting plate 2. At this time, rotate the fixing post 21, and the threaded post 24 will enter the second connecting plate 2. Continue to rotate the fixing post 21 until the threaded post 24 and the support platform 14 are also threadedly connected. When the equipment needs to be adjusted, turn the fixing post 21 in the opposite direction. When the threaded post 24 disengages from the second connecting plate 2, the second connecting plate 2 and the connecting plate 23 will lift the fixing post 21, making the threaded post 24 away from the second connecting plate 2. At this time, the positioning pin 18 can slide normally. By setting the second connecting plate 2 and the fixing post 21, the stability of the connection between the positioning pin 18 and the positioning hole 13 is increased when the equipment is working, the probability of the positioning pin 18 sliding during equipment operation is reduced, the situation of equipment failure caused by the sliding of the positioning pin 18 is reduced, and the stability of the equipment during operation is increased.

[0023] Reference Figure 5 The inner sidewall of the support platform 14 has a limiting groove 3, the inner sidewall of the limiting groove 3 slides in contact with the limiting disk 31, the top of the outer sidewall of the limiting disk 31 is fixedly connected to the limiting rod 32, the outer sidewall of the limiting rod 32 is fixedly connected to the first connecting plate 17, and the outer sidewall of the limiting rod 32 slides in contact with the support platform 14.

[0024] When the equipment is working, when the first connecting plate 17 slides, the first connecting plate 17 will drive the limiting rod 32 to slide. The limiting rod 32 will slide under the restriction of the support platform 14. The limiting groove 3 and the limiting plate 31 will limit the maximum range of movement of the limiting rod 32. By setting the limiting rod 32, the stability of the first connecting plate 17 when sliding up and down is increased, the bending of the first connecting plate 17 when sliding during long-term operation is reduced, and the failure rate of the equipment is reduced.

[0025] Reference Figure 3 The inner wall of the second roller 11 is fixed with a first fixing block 4, and the side wall of the first roller 1 is fixed with a second fixing block 41. The first fixing block 4 and the support frame 15 are at the same height.

[0026] When the equipment is working, the first fixing block 4 and the second fixing block 41 will restrict the space for the support frame 15 to move. By setting the first fixing block 4 and the second fixing block 41, the situation where the second roller 11 disengages from the first roller 1 when the first roller 1 and the second roller 11 are pulled excessively is reduced, which makes it easier for the staff to use the equipment.

[0027] Reference Figure 6 A sleeve 5 is fixedly connected to the bottom of the outer side wall of the first connecting plate 17, and a fixed post 21 is slidably contacted on the inner side wall of the sleeve 5.

[0028] When the equipment is working, the sleeve 5 restricts the direction of movement of the fixed column 21. The sleeve 5 increases the stability of the fixed column 21 when it moves, making it easier for the staff to use the equipment.

[0029] Reference Figure 5 An auxiliary nut 6 is fixed to the top of the outer side wall of the hanging ring 10.

[0030] When the equipment is working, the operator can also connect some long bolts to the auxiliary nut 6. When the bolt is pulled, the auxiliary nut 6 and the first connecting plate 17 will move accordingly. By setting the auxiliary nut 6, the operator can increase the number of ways to pull the first connecting plate 17.

[0031] Reference Figure 5 The positioning pin 18 is made of a rigid material.

[0032] When the equipment is working, the positioning pin 18 plays an important limiting role. By setting the positioning pin 18 to a rigid material, the bending or breakage of the positioning pin 18 during long-term operation is reduced, thereby reducing the possibility of malfunctions in the equipment due to bending or breakage of the positioning pin 18.

[0033] Working principle: Before the equipment starts working, the first roller 1 and the second roller 11 are installed in their respective positions. An external hook-like object is inserted through the slot 101 and contacts the hanging ring 10. At this time, the hanging ring 10 is pulled, causing the first connecting plate 17 to move. The positioning pin 18 will then disengage from the positioning hole 13, pulling the second roller 11 to the other side. When the second roller 11 and the first roller 1 are separated to a suitable position, the tension applied to the hanging ring 10 is released, and the position of the positioning hole 13 is adjusted. The second spring 19 pushes the first connecting plate 17, and the first spring 16 pulls the first connecting plate 17, thereby causing the positioning pin 18 to re-enter the positioning hole 13. Under the constraint of the limiting block 12 and the support platform 14, when the first roller 1 rotates, the second roller 11... The cylinder 11 will rotate accordingly. Through the support platform 14 and positioning pin 18, the overall length of the equipment can be extended, allowing it to adapt to different working scenarios. This facilitates adjustments by the operator based on actual conditions, reducing the difficulty of equipment replacement. After adjustment, the operator can use a screwdriver to contact the fixing post 21 and press it down until the threaded post 24 contacts the second connecting plate 2. Rotating the fixing post 21 at this point will cause the threaded post 24 to enter the second connecting plate 2. Continue rotating the fixing post 21 until the threaded post 24 and support platform 14 are also threadedly connected. When adjustments are needed, reverse the rotation of the fixing post 21. When the threaded post 24 disengages from the second connecting plate 2, the second connecting plate 2 and connecting disc 23 will... The fixed column 21 is lifted, causing the threaded column 24 to move away from the second connecting plate 2. At this time, the positioning pin 18 can slide normally. The second connecting plate 2 and the fixed column 21 increase the stability of the connection between the positioning pin 18 and the positioning hole 13 during equipment operation, reduce the probability of the positioning pin 18 sliding during equipment operation, reduce the possibility of equipment failure due to the sliding of the positioning pin 18, and increase the stability of the equipment during operation. When the first connecting plate 17 slides during equipment operation, the first connecting plate 17 will drive the limiting roller 32 to slide. The limiting roller 32 will slide under the restriction of the support platform 14. The limiting groove 3 and the limiting plate 31 will limit the maximum range of movement of the limiting roller 32. The first connecting plate 32 and the limiting plate 31 increase the stability of the connection between the positioning pin 18 and the positioning hole 13 during equipment operation. The stability of the connecting plate 17 during its up-and-down sliding is improved, reducing the likelihood of bending during prolonged operation and lowering the equipment failure rate. During operation, the first fixing block 4 and the second fixing block 41 restrict the movement of the support frame 15. These blocks also reduce the risk of the second roller 11 detaching from the first roller 1 when excessively pulled, facilitating equipment operation. Furthermore, the sleeve 5 restricts the direction of movement of the fixed column 21, increasing its stability and further enhancing equipment usability. Additionally, long bolts can be connected to the auxiliary nut 6 during operation.When the bolt is pulled, the auxiliary nut 6 and the first connecting plate 17 will move accordingly. The auxiliary nut 6 provides an additional way for the operator to pull the first connecting plate 17. During equipment operation, the positioning pin 18 plays a crucial limiting role. By making the positioning pin 18 a rigid material, the likelihood of bending or breaking during prolonged operation is reduced, thus minimizing the possibility of malfunctions in the equipment's fit due to bending or breakage of the positioning pin 18.
