Description

Technical Field

[0001] The utility model relates to the technical field of sports equipment, and particularly relates to a new - structured judo mat. Background Art

[0002] The structure of a judo mat is generally from top to bottom: judo cloth + upper inner tube + fiber board + lower inner tube + anti - slip layer, as Figure 1 shown. Among them, the fiber board plays the functions of preventing the formed mat from being too soft and having a middle depression. At the same time, the fiber board can prevent the phenomenon of thermal expansion and contraction of the inner tube.

[0003] At present, most of the judo mats on the market adopt the above - mentioned structure. The structure of the fiber board has the following disadvantages:

[0004] 1. The fiber board is processed by a process of mixing shredded wood chips and adhesive, and its materials are not environmentally friendly;

[0005] 2. The fiber board is greatly affected by temperature and humidity, and it is easy to cause deformation of the mat.

[0006] In view of this, in - depth research has been carried out on the above - mentioned disadvantages, and improvements have been made one by one. Content of the Utility Model

[0007] Aiming at the deficiencies of the prior art, the utility model provides a new - structured judo mat, which adopts a new structure to replace the existing fiber board, improves the strength, can avoid being affected by temperature and humidity, and at the same time achieves the purpose of cost saving.

[0008] The utility model is realized by the following technical solutions:

[0009] A new - structured judo mat is provided, which includes an inner tube and a judo cloth wrapped outside the inner tube. A sandwich layer is arranged in the inner tube to divide the inner tube into upper and lower parts. The sandwich layer includes an upper plate, a lower plate and a net - shaped framework body connected between the two plates.

[0010] Furthermore, the shape of the upper surface of the net - shaped framework body is the same as that of the upper plate, the shape of the lower surface of the net - shaped framework body is the same as that of the lower plate, and the thickness of the net - shaped framework body is greater than the thickness of the upper plate or the lower plate.

[0011] The thickness of the net - shaped framework body is greater than the thicknesses of the upper plate and the lower plate. The net - shaped framework body can deform and has a certain restoring force, which can be used to resist deformation, making the judo mat not easy to deform.

[0012] Furthermore, the upper plate is adhesively fixed to the bottom surface of the upper inner tube, and the lower plate is adhesively fixed to the top surface of the lower inner tube.

[0013] The upper plate and the lower plate are adhesively fixed to the upper inner tube and the lower inner tube respectively, which is convenient for connection and fixation.

[0014] Furthermore, the upper layer board, the lower layer board, and the net-shaped framework body are all made of the same material, which can be one of plastic, paper guard board, or metal guard board.

[0015] Compared with fiber board, plastic board has better high-temperature and low-temperature resistance performance and is not easy to deform. Compared with fiber board, cardboard can ensure the strength of the sandwich layer and has good low-temperature and high-temperature resistance performance. At the same time, due to the waterproof performance of the judo cloth's leather, it can also maintain a good waterproof effect. Compared with fiber board, metal guard board has better strength and is less affected by temperature and humidity than fiber board. At the same time, it is more environmentally friendly.

[0016] Furthermore, the cross-sectional shape of the mesh of the net-shaped framework body is one of triangle, circle, or polygon.

[0017] The shape of the mesh of the net-shaped framework body is not limited, and any one of triangle, circle, or polygon can be selected for use.

[0018] Preferably, an anti-slip layer is provided on the bottom surface of the judo cloth.

[0019] By providing the anti-slip layer, the stability of the judo mat can be enhanced, so that it can maintain the stability of its position during use, is not easy to move, and ensures the safety of athletes.

[0020] The beneficial effects of the present utility model:

[0021] The present utility model changes the sandwich layer into a three-dimensional structure of a net-shaped framework body cooperating with an upper layer board and a lower layer board. By connecting the upper layer board with the upper inner tube and the lower layer board with the lower inner tube, and cooperating with the deformation maintaining effect of the middle net-shaped framework body, the anti-deformation ability of the judo mat can be greatly improved. At the same time, replacing the fiber board with one of plastic, paper guard board, and metal guard board can effectively solve the problems of warping and deformation of the judo mat caused by temperature and humidity changes, improve the overall strength, and the structural performance is more stable. The upper layer board and the lower layer board can be strongly bonded to the upper and lower layers of the inner tube through an adhesive, which can inhibit the phenomenon of thermal expansion and contraction of the inner tube, significantly improve the product quality, save raw materials, reduce the corresponding cost, help expand the market share, and improve customer satisfaction.
