As shown in fig. 1, the telescopic support rods 2 are horizontal rods parallel to the horizontal plane, three telescopic support rods 2 are provided, the three telescopic support rods 2 are installed at the rear section of the support containing seat 1 and are in a shape like a Chinese character 'pin', the middle position of each telescopic support rod 2 is stabilized in a structure like a Chinese character 'pin', one telescopic support rod 2 in the middle is also located between two net support rods 3, the telescopic support rod 2 in the middle facilitates the user to lift the whole set of device, and the net support rod 3 is a vertical rod which can rotate and then stand up as shown in fig. 2.

The supporting and accommodating seat 1 is provided with a mounting position of a rotary positioning angle adjusting assembly 2, the rotary positioning angle adjusting assembly 2 comprises a rotating shaft 111 and an adjusting piece, the adjusting piece is arranged on the rotating shaft 111, and the rotating shaft 111 is adjustably mounted at the mounting position of the rotary positioning angle adjusting assembly 2; the rotating shaft 111 is provided with a stand mounting position 112 for mounting the net support stick 3. After the rotational positioning angle adjusting assembly 2 is installed at the installation position of the rotational positioning angle adjusting assembly 2, the positioning member 115 supports the lock of the rotating shaft 111 to the storage seat 1, the positioning member 115 is provided with a fixing hole 1151 and a limiting groove 1152, the limiting groove 1152 is a curved groove, the curved surface of the limiting groove 1152 is connected with the rotating shaft 11, and a screw passes through the fixing hole 1151 to lock the positioning member 115 and the rotating shaft 111 to the storage seat 1.

As shown in fig. 12 and 13, the rotational positioning angle adjusting assembly 2 is essentially a structure of rotation, positioning, and snap-fixing, wherein the rotational positioning angle adjusting assembly 2 may be the following structure.

As one embodiment, the adjusting member of the rotational positioning angle adjusting assembly 2 is composed of a rotating gear 113 and a positioning plate 116, that is, the rotating gear 113 and the rotating member, and the positioning plate 116 is a positioning member for positioning the rotation angle of the rotating gear 113.

The rotary gear 113 is fixedly mounted on the rotating shaft 111 of the rotational positioning angle adjusting assembly 2, the positioning plate 116 is mounted on the positioning control block 114, the positioning control block 114 is used for limiting the rotation of the rotary gear 113 by controlling the contact between the positioning plate 116 and the rotary gear 113, one end of the positioning control block 114 is mounted on the supporting and receiving seat 1 through a shaft (i.e., one section of the positioning control block 114 can rotate around the shaft), the other end of the positioning control block 114 is connected with a spring, and when the spring is in a static state, the positioning plate 116 is located right below the rotating shaft 111. The above-described structure of the positioning piece 116 and the rotary gear 113 is only one example of the rotational positioning angle adjusting assembly 2, and in practice, the opening direction of the rotary gear 113 and the positioning piece 116 is opposite when the net support stick 3 is rotated inward. The reverse design of spacer 116 and rotatory gear 113 is the rotation angle that is used for fixing rotatory location angle adjusting part 2, makes things convenient for the angle modulation of actual product, and actual spacer 116 and rotatory gear 113 are mounting and rotating member, and the effect of mounting is used for fixed rotating member pivoted angle, and convenience of customers fixes actually required angle.

Such a rotary positioning angle adjustment assembly 2 described above is only one of the typical, simple and convenient ways of operating the present invention, but not the only way. As a simple modification of this patent, the rotational positioning angle adjusting unit 2 may be a relatively simple latch (see fig. 19 and 20), may be a manner in which two gears used in other fields press a rotational latch, or may have a circular concave-convex disk structure as shown in fig. 21 and 22. Meanwhile, in actual production, the pure mechanical structure in the scheme can be replaced by an intelligent control mechanical structure according to the selection of actual use conditions and the existing control modes such as electric control, magnetic control, oil control or pneumatic control. When a football gate with a larger supporting frame or a supporting frame for temporary large posters is manufactured, the rotation and the rotated angle positioning of the electric control, magnetic control, oil control or pneumatic control bracket are more suitable for the use of actual scenes.

The support storage 1 is provided with a limit protrusion 14 for limiting the maximum rotation angle of the net support stick 3.

For better use of the matching limiting protrusions 14, the ball net supporting rod 3 in the scheme adopts a triangular ball net supporting rod with a triangular cross section.

As shown in fig. 1 to 8, the number of the telescopic support rods 2 in the present scheme is three, and the three telescopic support rods 2 are spatially parallel, the cross section formed after the three telescopic support rods 2 are installed on the support containing seat 1 is in a delta-shaped structure, wherein one telescopic support rod 2 in the middle has the effect of stabilizing the base.

The connecting sleeve comprises a supporting connecting sleeve 5 connected with the telescopic supporting rods 2 positioned at two sides of the supporting and containing seat 1 and a stable connecting sleeve 43 connected with the telescopic supporting rods 2 positioned at the middle part of the supporting and containing seat 1.

The telescopic positioning component comprises a limiting clamping groove 45 arranged on the connecting sleeve and a limiting part 46 arranged corresponding to the limiting clamping groove 45, corresponding positioning grooves are arranged on the telescopic supporting rod 2, and during positioning, the limiting part 46 sequentially penetrates through the limiting clamping groove 45 and the positioning grooves to fix the length of the telescopic supporting rod 2. The position-limiting member 46 may be a knife switch as shown in fig. 11, and when the knife switch is used, the telescopic supporting rod 2 pulled up by the knife switch can be extended towards two ends, and the telescopic supporting rod 2 is extended to increase the stability of the whole support. The nonadjustable support of base interval on the existing market, so general base interval all is far less than the support and opens the back completely (see fig. 2 after the support is opened completely, similar structure of fig. 2) net length of upper end for convenient outdoor use, when support weight is the same, the interval of base is the littleer whole stability of whole support more, so the above-mentioned scheme that can carry out base interval regulation has been proposed in this scheme, with the problem of the inconvenient regulation of present base interval in solving this trade, the on the other hand that the bracing piece can be adjusted also makes things convenient for accomodating of device, the space that the product occupied when not using is less.

Above scheme also can be used in portable tent support in practical application, makes things convenient for the buildding and accomodating of tent. The scheme of the invention meets the requirements of consumers on portability, easiness in collection, convenience in construction and the like of the bracket in the construction of the bracket, so that the scheme of the invention is greatly popularized in the field of bracket production and manufacturing, and products in the field can better meet the market demands.

The above embodiments are only for illustrating the invention and are not to be construed as limiting the invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention, therefore, all equivalent technical solutions also belong to the scope of the invention, and the scope of the invention is defined by the claims.
