Description

Technical Field

[0001] The utility model relates to the technical field of bases of vertical poles of sports equipment, in particular to a pole insertion base which is convenient for storage. Background Art

[0002] Some sports require the use of vertical auxiliary equipment, such as signboards, scoreboards, target boards or midfield blocks. These devices are often placed on the sports field with poles to facilitate participants in the sports to obtain sports information.

[0003] Traditional sports venues are made of sandy soil, and the poles used in such venues are mostly equipped with a pointed tip at the lower end of the pole body. When in use, the staff directly inserts the pole body vertically into the sand layer so that the pole body can stand upright at the sports venue. Now with the advancement of technology, in order to better protect athletes and improve their sports experience, modern sports venues mostly have ground paving layers, such as plastic venues, EPDM floors, PVC indoor courts or acrylic courts. The surface of such venues cannot be equipped with pointed poles. For this reason, a sleeve pole base that can be equipped with pole bodies has been derived. The sleeve pole base is divided into two application methods: fixed and movable. The fixed sleeve pole base is often fixed to a certain place on the surface by pouring or bolting structure; the movable sleeve pole base is often equipped with a counterweight block and sits on the ground when in use, and its position is relatively free.

[0004] The sleeve rod insertion base usually includes a base plate for assembly and a sleeve for inserting the rod. When in use, the base plate's reference surface and the sleeve's axis need to be in a vertical relative position, and the sleeve usually has a certain height: the fixed sleeve rod insertion base is left in the sports field during non-sports time, and the sleeve is relatively high, which easily interferes with the sports field's activity space; although the movable sleeve rod insertion base can be dismantled as needed, the vertical arrangement of the sleeve causes the storage space to be too large. Therefore, some sleeve rod insertion bases consider setting the sleeve into a hinged structure that can be folded and stored when not in use, thereby reducing the vertical space occupied by the sleeve seat. However, the inventor believes that this type of sleeve rod insertion base in which the sleeve is hinged to the base makes the sleeve's vertical positioning less stable. The hinged connection method inevitably has a large margin of motion, and therefore cannot guarantee the upright quality of the rod. The rod body may have an inclination angle, and in severe cases, there may be shaking, which is particularly obvious when the rod body is long. Utility Model Content
