Description

Technical Field

[0001] The invention relates to the field of sports stadium facilities and equipment, and more specifically to a side-insertion type composite sports floor pad. Background Art

[0002] At present, the overall structural level adjustment schemes of sports floors involved in the domestic and foreign sports flooring industry basically use wood materials such as solid wood and artificial boards as height adjustment pads, and all of them are randomly purchased solid wood square materials and artificial boards (mostly plywood) to make pads (sheets) of different specifications. During the assembly and construction of sports floors, if there is a large height difference in height adjustment, multiple blocks or sheets need to be stacked and placed, and adhesives need to be used as a medium between the stacked layers. It is impossible to accurately adjust the overall structure of the sports floor. The appearance quality is extremely poor, which seriously affects the continuous realization and guarantee of the functional technical indicators of the sports floor.

[0003] Moreover, the current use of leveling pads (sheets) for sports floor construction is mostly in the form of stacking multiple blocks or sheets together with latex glue (polyvinyl acetate emulsion) as a bonding medium. Although this method is low-cost, it cannot achieve the elastic properties of the pads. In addition, due to the stacking of multiple groups of pads (sheets), the center of gravity is inconsistent and the stability is poor. At the same time, height-adjusting pads (sheets) are usually used in natural environments with poor ventilation, long-term unconventional temperature and humidity. The latex glue (polyvinyl acetate adhesive) has defects such as its own use period being shorter than the same period. It is easy to cause the pads (sheets) themselves to weaken and the adhesive to fail after 2-3 years of use, resulting in the overall structural performance of the sports floor failing to meet the requirements of relevant level competitions, which greatly affects the high-value utilization of this high-value-added product.

[0004] In addition, the existing technology for adjusting the overall level of sports floors has no unified technical standards and normative document requirements. The level and height adjustment methods and pad structure are simple, the products are rough, the service life is short, and the quality is poor. They basically cannot meet the technical requirements of sports floors. Even if they meet the requirements of relevant standards in the short term, they cannot continuously guarantee the functional performance of sports floors, and they decrease linearly with the frequency of use of the venue, affecting the demand for sports floors for bidding and competitions. The existing level and height adjustment of sports floors is in the state of non-standard products. Although the pads currently used are low-cost, there is a serious waste of materials during their application. The existing sports floor pads have a single structure, no fixed products, great difficulty in adjusting the level and height, low precision, no technical standards and specifications, and the construction quality cannot be guaranteed.

[0005] Therefore, how to develop a floor pad product to effectively solve the above-mentioned key technical problems has become an important research topic for those skilled in the art. Summary of the invention

[0032] Example:

[0033] The invention discloses a side-insertion composite sports floor pad, which comprises an elastic block unit 1 and a height-adjusting card 2.

[0034] Specifically,

[0035] like Figure 1 , Figure 2 As shown, the elastic block unit 1 is a cubic structure as a whole, the upper surface of which is a support surface structure 3, and the lower surface is divided into four symmetrical base feet 5 by two cross-shaped guide slots 4.

[0036] Furthermore, the elastic block unit 1 is a cube having elastic properties molded from natural rubber or synthetic rubber.

[0037] Moreover, a plurality of triangular holes 12 are evenly arranged on the support surface structure 3 of the elastomeric block unit 1, that is, the upper surface of the elastomeric block unit 1 is designed as a multi-triangular hole-shaped support structure. The design of the plurality of triangular holes 12 not only saves materials for the production of the elastomeric block unit 1, but also achieves the required support effect. Moreover, the holes are designed to be triangular in order to cooperate with the square holes 6 on the lower surface, so that the elastomeric block unit 1 as a whole can be subjected to uniform and stable force up and down.

[0038] The guide slot 4 is a V-shaped slot structure with a flat bottom surface; three square holes 6 are designed on the lower surface of each base foot 5, and the three square holes 6 are arranged at the two outer sides of the corresponding base foot 5, so that the height adjustment card 2 can be inserted from any two convenient insertion end faces of the elastomer card block unit 1 to adjust the height of the overall structure.

[0039] At the same time, in addition to the three square holes 6 designed on the lower surface of each base foot 5, a triangular hole 15 is designed on the inner side of the three square holes 6. The design of three square holes 6 and one triangular hole 15 also makes the supporting structure of the four base feet 5 more stable.

[0040] In addition, a plurality of square guide slot holes are also provided on the bottom surface of the guide slot 4. The triangular hole 15 and the square guide slot holes are provided to save the material for making the elastic block unit 1.

[0041] A positioning hole 7 penetrating the upper and lower surfaces is designed at the center of the elastic block unit 1 for connection with the keel structure of the sports floor.

[0042] It should be noted that the triangular hole 12, the square hole 6, the triangular hole 15 and the guide slot square hole in the present invention are not through holes.

[0043] In the present invention, each guide slot 4 is divided into two short slots by the positioning hole 7, and the left and right sides at both ends of each short slot are designed as an inwardly expanded inclined wall surface 13, and the groove bottom surface located at the upper end of each short slot is designed as an upwardly inclined inclined bottom surface 14. The design of the inclined wall surface 13 and the inclined bottom surface 14 is to facilitate the smooth insertion of the guide positioning body 9 in the height adjustment card 2 into the guide slot 4.

[0044] Furthermore, the inclined wall surface 13 and the corresponding inner wall of the guide slot 4 form an angle of 5° to 10°; the inclined bottom surface 14 and the corresponding groove bottom surface of the guide slot 4 form an angle of 5° to 10°.

[0045] like Figure 3 As shown, the height adjustment card 2 is flat as a whole, and includes a plane base 8, a guide positioning body 9, a non-return lock 10 and a limit stop 11. There are two plane bases 8, and the guide positioning body 9 is connected between the two plane bases 8, and it is in a V-shape that can be matched with the guide slot 4.

[0046] Furthermore, the height adjustment card 2 is made of a high molecular thermoplastic material by compression molding.

[0047] In the present invention, the plane base 8 is a plane grid porous structure, and at the same time, a plurality of openings are also provided on the side wall of the guide positioning body 9 to save materials for the production of the height adjustment card 2.

[0048] A non-return lock 10 is designed on the upper surface of the flat base 8 and can be adapted to be snapped into the square hole 6 .

[0049] With the direction of the height adjustment card 2 being inserted into the elastic block unit 1 as the front, the limit latch 11 is designed to be vertical as a whole and is located at the rear side of the two planar bases 8, and is connected to the rear end of the guide positioning body 9. When the guide positioning body 9 is fully inserted into the guide slot 4, the limit latch 11 will be against the side surface of the elastic block unit 1, and the two non-return latches 10 will be inserted into the corresponding square holes 6 on the lower surface of the elastic block unit 1.

[0050] In the present invention, the front end face of the guide positioning body 9 is an inclined end face 16 which is gradually inclined backward from bottom to top, that is, the front end face has a certain inclination angle. The inclined end face 16 has the same design concept as the inclined wall surface 13 and the inclined bottom surface 14 on the elastomer block unit 1, and is also for the convenience of the guide positioning body 9 to be smoothly inserted into the guide slot 4.

[0051] In the present invention, the depth of the guide slot 4 is slightly greater than the height of the guide positioning body 9, generally 0.5 mm to 1 mm, so that the upper surface of the plane base 8 and the lower surface of the elastic block unit 1 can be in close contact during installation.

[0052] Meanwhile, the height adjustment card 2 of the present invention is designed with multiple specifications, and the thickness of each specification is different, and the usual thickness range is 1mm to 15mm. When necessary, multiple height adjustment cards 2 of suitable specifications can be used to adjust the height of the overall structure of the sports floor.

[0053] like Figure 4As shown, if multiple height adjustment cards 2 are needed to adjust the height of the overall structure, the multiple height adjustment cards 2 will be inserted in sequence from the guide slot 4 of the elastomeric card block unit 1 and the bottom slot of the guide positioning body 9 corresponding to the previous height adjustment card 2, and their respective limit card blocks 11 will also be in contact with the side surface of the elastomeric card block unit 1 or the side surface of the limit card block 11 corresponding to the previous height adjustment card 2.

[0054] The present invention is a composite sports floor pad composed of a brand-new side-insertion height adjustment card 2 and an elastomeric card block unit 1. The pad is positioned and supported between a guide positioning body 9 and a guide card slot 4 that correspond to each other and have a certain inclination angle, thereby adjusting the overall structural height of the sports floor, ensuring the overall structural stability and functionality of the sports floor. It has a series of advantages such as convenient construction, durability, good elasticity, and the ability to accurately adjust the overall structural horizontal height of the sports floor. It is mainly used for leveling the overall structural height of indoor and outdoor sports floors, thereby ensuring the technical, performance and safety requirements for holding related sports competitions, cultural and entertainment activities.

The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
