[0018] Advantageous Effects

[0019] The present invention provides a split rubber crawler. Compared with the prior art, the following advantageous effects are achieved:

[0020] 1. For this split rubber crawler, by passing a pin through the connecting ear and fixing both ends with a locking nut and a threaded post, at this time, the reinforcing sleeve is rotatably arranged inside the connecting ear. During operation, the arc-shaped caps are installed inside the reinforcing grooves, with multiple groups arranged in a circle around the reinforcing sleeve and multiple layers arranged vertically. It has high-strength radial anti-pull-out performance, does not affect the movement between multiple groups of skeleton bodies, ensures the connection strength during the use of the product, guarantees the integrity of the crawler, and compared with the integral rubber crawler structure, it can reduce the processing procedures, reduce the scrap rate, and is convenient to assemble and can be quickly disassembled and replaced.

[0021] 2. For this split rubber crawler, it is positioned by inserting the positioning strip into the positioning hole, and glue is applied avoiding the positions of the connecting ear, the groove, the discharge groove and the limiting block. The rubber main body is adhered to the upper surface of the metal plate. The limiting block passes through the corresponding limiting opening, and under the connection of the inserting block, the movable block slides inside the metal plate and compresses the compression pad, that is, the rubber main body can provide a buffer space through the movable block and the compression pad when being squeezed, thereby improving the elastic force.

[0022] 3. For this split rubber track, by turning the adjusting stud, the position of the ejector rod can be adjusted through the docking block, thereby adjusting the protruding length of the ejector rod and the ejector block. The anti-sticking convex block enters the inside of the groove. Under the ejection action of the ejector block, the anti-sticking convex block can be switched between a slightly bulging state and a flat state. Refer to the attached Figure 1 , the existing rubber sheets are all provided with convex patterns to prevent slipping. The anti-slip convex blocks cooperate with the convex patterns to strengthen the support. Coupled with the state switching of the anti-sticking convex blocks, the adhesion such as silt on the surface of the rubber main body can be cleaned, and slipping can be further prevented.

The bottom of the groove 122 is communicated with a storage groove 126, a docking groove 127 and an adjustment groove 128. The docking groove 127 is communicated between the storage groove 126 and the adjustment groove 128, and the adjustment groove 128 is located at the bottom of the docking groove 127. The top of the metal plate 12 is also fixedly provided with anti-slip bumps 125, and the limit block 124 is arranged in a staggered manner with the anti-slip bumps 125. The surface of the rubber main body 2 is fixedly provided with convex stripes, and several groups of convex stripes are correspondingly arranged between the convex stripes and the anti-slip bumps 125. Several groups of positioning strips 211 are correspondingly arranged for the positioning holes 111, and the positioning strips 211 movably penetrate through the corresponding positioning holes 111. The groove 122 corresponds to the anti-sticking bump 22. By turning the adjustment stud 14, the position of the ejector rod 13 can be adjusted through the docking block 15, so as to adjust the extending length of the ejector rod 13 and the ejector block 16. The anti-sticking bump 22 enters the groove 122. Under the ejecting action of the ejector block 16, the anti-sticking bump 22 can be in a slightly bulging and flat state switching. The existing rubber sheets are all provided with convex stripes to prevent slipping. The anti-slip bumps 125 cooperate with the convex stripes to strengthen the support. Coupled with the state switching of the anti-sticking bumps 22, the adhesion such as silt on the surface of the rubber main body 2 can be cleaned.

[0037] Please refer to Figures 6-8 Both ends of the pin rod 3 are fixedly provided with threaded posts 33. One end of the threaded post 33 is threadedly connected with a locking nut 31. The outer circumference of the pin rod 3 is fixedly provided with a reinforcing sleeve 32. The outer circumference of the reinforcing sleeve 32 is provided with a reinforcing groove 321. A reinforcing column 322 is fixedly arranged inside the reinforcing groove 321. One end of the reinforcing column 322 is fixedly connected with an arc-shaped cap 323. The pin rod 3 is passed through the connecting ear 121 and fixed at both ends through the locking nut 31 and the threaded post 33. At this time, the reinforcing sleeve 32 is rotatably arranged inside the connecting ear 121. During work, the arc-shaped cap 323 is installed inside the reinforcing groove 321, and several groups are arranged in a circle around the reinforcing sleeve 32 and multiple layers are arranged vertically, having high-strength radial tensile and pulling properties and not affecting the activities between multiple groups of skeleton bodies 1.

An adjusting stud 14 is connected to the interior of the adjusting groove 128 by means of threads, and the bottom end of the adjusting stud 14 is hidden inside the metal plate 12. A docking block 15 is slidably arranged inside the docking groove 127, and the docking block 15 is fixedly arranged at the bottom end of the ejector rod 13. A top block 16 is fixedly arranged at one end of the ejector rod 13 away from the docking block 15, and the top block 16 is movably arranged inside the groove 122. The positioning piece 21 is inserted into the interior of the positioning hole 111 through the positioning strip 211 for positioning. Glue is applied while avoiding the positions of the connecting ear 121, the groove 122, the discharge groove 123, and the limiting block 124. The rubber main body 2 is adhered to the upper surface of the metal plate 12. The limiting block 124 passes through the corresponding limiting opening 23.

A plurality of groups are arranged in a circle around the reinforcing sleeve 32 and multiple layers are arranged vertically, having high-strength radial tensile and pulling-out performance, not affecting the movement between multiple groups of skeleton bodies 1, ensuring the connection strength during the use of the product, guaranteeing the integrity of the crawler. Compared with the integral rubber crawler structure, it can reduce the processing procedures, reduce the rejection rate, and is convenient for assembly, can be quickly disassembled and replaced. The positioning piece 21 is inserted into the interior of the positioning hole 111 through the positioning strip 211 for positioning. Glue is applied while avoiding the positions of the connecting ear 121, the groove 122, the discharge groove 123, and the limiting block 124. The rubber main body 2 is adhered to the upper surface of the metal plate 12. The limiting block 124 passes through the corresponding limiting opening 23. Under the connection of the insertion block 1241, the movable block 1242 slides inside the metal plate 12 and compresses the compression pad 1243. That is, when the rubber main body 2 is squeezed, a buffer space can be provided through the movable block 1242 and the compression pad 1243, thereby increasing the elastic force. The groove 122 corresponds to the anti-sticking convex block 22. By turning the adjusting stud 14, the position of the ejector rod 13 can be adjusted through the docking block 15, thereby adjusting the protruding length of the ejector rod 13 and the top block 16. The anti-sticking convex block 22 enters the interior of the groove 122. Under the ejection action of the top block 16, the anti-sticking convex block 22 can be in a state of slightly bulging and flat state switching. Refer to the appendix Figure 1 , the existing rubber sheets are all provided with convex stripes to prevent slipping. The anti-slip convex blocks 125 cooperate with the convex stripes to strengthen the support. Coupled with the state switching of the anti-sticking convex blocks 22, the adhesion such as silt on the surface of the rubber main body 2 can be cleaned, further preventing slipping.
