[0030] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-Figure 8 , the utility model provides a technical solution:

[0032] A portable telescopic tripod steel frame includes a tripod body 1, which is composed of three telescopic rods 10 with the same structure and radial distribution. The same size maintains the stability of the tripod body 1, and the telescopic rods 10 are composed of a plurality of steel rods 100 with diameters decreasing from the outside to the inside, which are slidably connected to facilitate telescoping. The same snap plate 2 is arranged at the center of the three telescopic rods 10, and the three telescopic rods 10 are hinged to the edge of the snap plate 2 through the clamping hook located at the top end of the steel rod 100 at the innermost end, so that the telescopic rods 10 can be rotated outward. The top end of the snap plate 2 is fixed with a support 20 by bolts, and the top end of the support 20 is fixedly clamped with a magnetic ball 21, and the magnetic ball 21 is fixedly clamped. The outer wall ball joint is sleeved with a ball sleeve 22, and the support 20, the magnetic ball 21 and the ball sleeve 22 constitute a universal joint mechanism. A support plate 3 is provided between the three telescopic rods 10 directly below the snap plate 2. When the tripod body 1 is unfolded, the support plate 3 provides a supporting force. The center of the top surface of the support plate 3 is connected with a lower snap plate 31 through a cylinder. The outer wall of the steel rod 100 at the outermost end of the three telescopic rods 10 is fixedly sleeved with a connecting ring 30. The three connecting rings 30 are connected to the lower snap plate 31 through two connected branch chains 32. Through the mutual connection and cooperation of the lower snap plate 31, the connecting ring 30 and the branch chain 32, the tripod body 1 can be stably erected when unfolded.

[0033] In this embodiment, the bottom end surfaces of several steel rods 100 of different diameters are fixedly sleeved with magnetic blocking plates 101, so that the tripod body 1 is simple and easy to operate when folding and unfolding. The diameter of the blocking plates 101 is larger than the diameter of the steel rods 100 connected thereto. The blocking plates 101 are used to prevent the steel rods 100 from leaving their positions when the telescopic rods 100 are extended. At the same time, because of the magnetism, when the telescopic rods 100 are fully extended, they can absorb the inner wall of the upper end of the steel rods 100 to enhance stability. The edge of the blocking plate 101 contacts the inner wall of the steel rods 100 sleeved on the adjacent outer side, so that the telescopic rods 10 are not easy to leave the original track when they are extended, and the extension is convenient.

[0034] In this embodiment, circular holes are formed on the top surfaces of several steel rods 100 of different diameters, and magnets 102 are fixedly connected to the side walls of several steel rods 100 near the top ends. The diameter of the circular holes on the top surfaces of the steel rods 100 is the same as the diameter of the steel rods 100 inserted on the adjacent inner sides, so that the telescopic rod 10 is not easy to deviate or slide obliquely when sliding up and down.

[0035] In this embodiment, a circular groove is formed on the bottom surface of the ball sleeve 22, and the ball sleeve 22 is rolled and sleeved on the outer wall of the magnetic ball 21 through the circular groove. This device constitutes a simple universal joint mechanism, which can be better installed and disassembled by magnetic attraction and can rotate flexibly.

[0036] In this embodiment, one end of the two branch chains 32 is hinged by a pin shaft, and the end of the branch chain 32 away from the hinge is fixed with a clamping hook by a screw. The two branch chains 32 are respectively hinged to the edges of the corresponding connecting ring 30 and the lower snap plate 31 through their clamping hooks. The branch chains 32 are used to connect the corresponding connecting ring 30 and the lower snap plate 31. At the same time, when the telescopic rod 10 is in use, it protects the tripod body 1 so that the tripod body 1 is not easily separated from the original position.

[0037] In this embodiment, an arc groove matching the size of the steel rod 100 located at the outermost end is opened at the edge of the support plate 3 in the direction corresponding to the three telescopic rods 10. When the telescopic rods 10 are retracted, the telescopic rods 10 will be engaged in the arc groove, making the telescopic rods 10 not easy to bend, while also protecting the support plate 3 from being squeezed.

[0038] In this embodiment, the bottom surfaces of the three outermost steel rods 100 are fixedly connected with pointed feet 11 for enhancing stability, and the tips of the pointed feet 11 are facing downward, so that the tripod body 1 can be placed on the ground more stably.

[0039] In this embodiment, a storage plate 23 for mounting external instruments is fixed to the top of the ball sleeve 22 by bolts, and a handle 230 for adjusting the position of the storage plate 23 is fixed to one side wall of the storage plate 23 by bolts, so that the position of the storage plate 23 can be easily adjusted by the handle 230.

[0040] When the portable telescopic tripod steel frame of the utility model is in use, the telescopic rods 10 are firstly unfolded outwards respectively, and the telescopic rods 10 are stretched. When the telescopic rods 10 are stretched and reach the inner wall of the upper end of the steel rod 100, the blocking plate 101 can prevent the steel rod 100 from deviating from its track because its diameter is larger than the diameter of the steel rod 100 connected to its outer side. At the same time, the blocking plate 101 will be stuck at the inner wall of the upper end of the adjacent steel rod 100, and the blocking plate 101 and the inner wall of the upper end of the steel rod 100 are both provided with magnets, and the adjacent blocking plates 101 and magnets 102 will be adsorbed to enhance the firmness. In addition, the bottom surface is sleeved with a pointed support foot 11 with a pointed end downward, so that the tripod body 1 can be placed on the ground more stably, and the support 20, the magnetic ball 21 and the ball sleeve 22 constitute a universal joint mechanism, which is convenient for adjusting the position of the storage plate 23; this portable telescopic tripod steel frame is easy to fold up, has a simple structure and is low in cost.

[0041] The above shows and describes the basic principle, main features and advantages of the present embodiment of the utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiment. The above embodiment and description are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present embodiment may have various changes and improvements, which fall within the scope of the present utility model to be protected. The scope of protection claimed by the present utility model is defined by the attached claims and their equivalents.
