Utility Model Content

[0005] The utility model aims to solve or at least alleviate an existing anti-derailment track iron tooth. After a positioning column is inserted into a positioning hole of a rubber track, an iron tooth body is knocked to insert a steel cone into the inside of the rubber track, and then an adhesive is poured into a connection between the iron tooth body and the rubber track, so that the iron tooth body and the rubber track are connected. However, when debonding occurs between the iron tooth body and the rubber track, during use, the steel cone inserted into the rubber track and the positioning column plugged into the positioning hole may be passively pulled out, resulting in a derailment problem between the iron tooth body and the rubber track.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] By adopting the above technical scheme, when in use, the insert tube is inserted into the positioning hole of the rubber track, and then the bolt is moved downward in the insert tube by rotating the bolt, so that the pressure block squeezes the pressure plate, and the pressure plate is moved close to the inner wall of the insert tube, and the fixing nail is pushed out of the insert tube and inserted into the side wall of the positioning hole, and the insert tube is fixed in the positioning hole to prevent it from being pulled out, thereby avoiding as much as possible the problem that the steel cone inserted into the rubber track and the positioning column plugged into the positioning hole may be passively pulled out, resulting in the derailment of the iron tooth body and the rubber track.

[0009] Optionally, the fixing pins are sleeved with springs, and two ends of the springs are fixedly connected to the slider and the insert tube respectively.

[0010] By adopting the above technical solution, the spring can prevent the fixing nail from sliding out of the cannula when the cannula is inserted into the positioning hole, thereby making it difficult to insert the cannula.

[0011] Optionally, an accommodating groove is provided on the upper surface of the iron tooth body at the location of the bolt.

[0012] By adopting the above technical solution, the bolt can be received in the receiving groove when it moves downward, so as to prevent the bolt from being exposed and the bolt from being rotated and screwed out due to collision during use.

[0013] Optionally, triangular support plates are fixedly connected to both sides of the upper surface of the iron tooth body.

[0014] By adopting the above technical solution, the rigidity of the tooth block on the iron tooth body can be enhanced through the triangular support plate.

[0015] Optionally, a plurality of grooves are provided on the upper surface of the iron tooth body.

[0016] By adopting the above technical solution, when the adhesive is poured into the connection between the iron tooth body and the rubber track for connection, the contact area between the rubber track and the iron tooth body can be increased through the groove, thereby improving the stability of the connection.

[0017] Optionally, a reinforcement plate is fixedly connected to the lower surface of the iron tooth body, and a plurality of equidistantly distributed steel nails are fixedly connected to the lower surface of the reinforcement plate.

[0018] By adopting the above technical solution, after the insert tube is inserted into the positioning hole, the steel nail is inserted into the rubber track by knocking the iron tooth body, which can improve the stability of the connection between the iron tooth body and the rubber track.

[0019] Optionally, the height of the pressing block is greater than the length of the pressing plate.

[0020] By adopting the above technical solution, through the pressure block that is longer than the pressure plate, when the bolt contacts the pressure plate and cannot move downward, the pressure block can completely squeeze the pressure plate, so that the pressure plate fits against the inner wall of the insert tube and the fixing nail is completely pushed out.

[0021] In summary, the beneficial effects of this application are as follows:

[0022] 1. The present application is provided with coordination between structures such as bolts, pressure plates and fixing nails. When in use, the insert tube is inserted into the positioning hole of the rubber track, and then the bolt is moved downward in the insert tube by rotating the bolt, so that the pressure block squeezes the pressure plate, the pressure plate is brought close to the inner wall of the insert tube, the fixing nail is pushed out of the insert tube, and inserted into the side wall of the positioning hole, the insert tube is fixed in the positioning hole to prevent it from being pulled out, and the steel cone inserted into the rubber track and the positioning column plugged into the positioning hole may be passively pulled out, which may cause the iron tooth body and the rubber track to derail;

[0023] 2. The receiving groove allows the bolt to be received in the receiving groove when it moves downward, thereby preventing the bolt from being exposed and causing the bolt to collide during use and be screwed out. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] When in use, insert the insert tube 2 into the positioning hole of the rubber track, and then move the bolt 3 downward in the insert tube 2 by rotating the bolt 3, so that the pressure block 13 squeezes the pressure plate 4, and the pressure plate 4 is close to the inner wall of the insert tube 2, and the fixing nail 6 is pushed out of the insert tube 2 and inserted into the side wall of the positioning hole, and the insert tube 2 is fixed in the positioning hole to prevent it from being pulled out, thereby avoiding the problem that the steel cone inserted into the rubber track and the positioning column plugged into the positioning hole may be passively pulled out, causing the iron tooth body and the rubber track to derail.

[0031] Reference Figure 3 The fixing nails 6 are sleeved with springs 7, and the two ends of the springs 7 are fixedly connected to the slider 5 and the cannula 2 respectively. The springs 7 can prevent the fixing nails 6 from sliding out of the cannula 2 when the cannula 2 is inserted into the positioning hole, making it difficult to insert the cannula 2.

[0032] Reference Figure 1 The upper surface of the iron tooth body 1 is provided with a receiving groove 8 at the bolt 3. When the bolt 3 moves downward, it can be accommodated in the receiving groove 8 to prevent the bolt 3 from being exposed and causing the bolt 3 to be rotated and screwed out due to collision during use.

[0033] Reference Figure 1 Triangular support plates 9 are fixedly connected to both sides of the upper surface of the iron tooth body 1, and the triangular support plates 9 can enhance the rigidity of the tooth block on the iron tooth body 1.
