Technical Field
[0001] This utility model relates to the field of anti-skid chain technology, specifically an anti-skid chain with anti-skid studs for forestry equipment. Background Technology
[0002] Forest equipment anti-slip chain with anti-slip studs is an anti-slip chain with anti-slip studs that is installed on the bottom of equipment that is moved in the forest.
[0003] Based on the above, the inventors have discovered that: Currently, there are many anti-skid chains for forestry equipment on the market, but generally, the anti-skid chains for forestry equipment are directly fixed to the bottom of the equipment by workers. This results in poor grip on the forest ground, easily causing the equipment to slip during movement and affecting its normal movement on forest surfaces, thus reducing the effectiveness of the anti-skid chains. Therefore, in view of this, the inventors have researched and improved the existing structure to provide an anti-skid chain with studs for forestry equipment, aiming to achieve a more practical purpose. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] The anti-slip mechanism includes:
[0007] Two elastic plates are provided, the inner walls of which are matched with the outer wall of the chain body. Several anti-slip nails are fixed at the bottom of the two elastic plates, and two recesses are provided at the top of the two elastic plates. All four recesses are provided on the outer wall of the chain body.
[0008] As a preferred technical solution of this utility model, the outer wall of the chain body is provided with two cover plates, the bottom end of each of the two cover plates is fixed with a locking block, the top end of each of the two elastic plates is provided with a locking groove, and the inner wall of each locking groove is matched with the outer wall of the locking block.
[0009] As a preferred technical solution of this utility model, each of the two elastic plates has four square grooves at its top, and the inner walls of the eight square grooves are provided with square blocks, and the top of each of the eight square blocks is fixed to the bottom of the concave block.
[0010] As a preferred embodiment of this utility model, horizontal columns are fitted on both sides of the two elastic plates, and the outer walls of the four horizontal columns are matched with the inner walls of the block.
[0011] As a preferred technical solution of this utility model, the bottom ends of the four horizontal columns are provided with two groove plates, the top ends of the two groove plates are fixed to the bottom ends of the elastic plate, the inner walls of the two groove plates are matched with two limiting posts, and the outer walls of the four limiting posts are sleeved with the inner walls of the horizontal columns.
[0012] As a preferred embodiment of this utility model, the fixing mechanism includes:
[0013] Two concave plates, one side of each concave plate is fixed to one side of the connecting block, and the inner wall of each of the two concave plates is threaded with two screws.
[0014] As a preferred embodiment of this utility model, each of the two concave plates has two cover plates at its bottom end, the inner walls of the four cover plates are fitted with the outer walls of the screws, the top ends of the four cover plates are fixed with two inserts, and the outer walls of the eight inserts are matched with the inner walls of the concave plates.
[0015] The beneficial effects of this utility model are:
[0016] 1. This solution involves engaging the inner wall of the elastic plate with anti-slip studs to the outer wall of the chain body. The inner wall of the recessed block slides against the outer wall of the chain body until its bottom contactes the top of the elastic plate, allowing the square block fixed at its bottom to insert into the inner wall of the square groove. The outer wall of the horizontal column is fitted onto one side of the elastic plate, matching the inner wall of the square block. The outer wall of the limiting post is fitted onto the inner wall of the horizontal column until its bottom engages with the inner wall of the groove plate. This securely installs the elastic plate with anti-slip studs on the outer wall of the chain body, effectively increasing the grip between the anti-slip chain and the forest ground. It also allows workers to periodically remove and reinstall the elastic plate with anti-slip studs from the chain body, preventing wear and tear on the studs over time and effectively improving the device's practicality.
[0017] 2. This solution uses the inner wall of the cover plate to engage with the outer wall of the chain body, allowing the locking block at the bottom of the cover plate to insert into the inner wall of the slot. This further secures the chain body and the elastic plate, enhancing the stability of the installation between them and preventing the elastic plate from easily detaching from the chain body under stress. Therefore, it effectively improves the performance of the anti-skid chain. Attached Figure Description
