According to
In the embodiment, the rotation of the handle 85 can drive the positioning block 82 to move and keep close or far away from the positioning rack 81. When the positioning block 82 is close to the rack and the fixing tooth 821 is meshed with the contacting surface of the positioning rack 81, the positioning block 82 is fixed in a certain position of the stand column 1, so that the sliding block positioning mechanism 8 and the sliding block shell 21 can be fixed in a certain position of the stand column 1; when the positioning block 82 is far away from the rack, the fixing tooth 821 is separated from the positioning rack 81, and the sliding block shell 21 can move along the stand column 1 and adjust the position. Since the fixing tooth 821 is meshed with the positioning rack 81 through contacting surface and the number of the fixing tooth 821 is more than two, the structure stress points can disperse onto the positioning rack 81, which ensures appropriate supporting strength and stable installation of the umbrella tent 4, and the umbrella tent 4 cannot be damaged easily by the wind.
As shown in
The sliding block positioning mechanism 8 also comprises an elastic reset part 83 connected with the sliding block shell 21 and other end 82b of the positioning block 82, so that the positioning block 82 can move toward the positioning rack 81. As shown in
Further, the elastic reset part 83 is a compression spring, with both ends pressing against the positioning block 82 and the sliding block shell 21, so that the positioning block 82 can move toward the positioning rack 81, and the fixing tooth 821 and the positioning rack 81 can be meshed firmly.
As shown in
As shown in
A rotating boss 851 is arranged at one end of the handle 85 and installed on the sliding block shell 21 in a rotating mode, also referred to as a rotating configuration. The rotating boss 851 is simple in structure and convenient to use, not only fixing one end of the handle 85, but also realizing the rotation of the handle 85.
In one embodiment, a columnar bulge is arranged at one end 85a of the handle 85. The positioning block 82 is provided with a groove 825, and a columnar bulge 852 is inserted in the assembly groove 825 to connect with the positioning block 82. The embodiment is simple in structure, easy to assemble and very convenient just by inserting the columnar bulge 852 of the handle 85 into the assembly groove 825 of the positioning block 82. In other embodiments, but not restricted to, the other end 85b end of the handle 85 can be connected with the positioning block 82 through pins or rivets, so as to facilitate use.
Further, the fixing tooth 821 are square teeth, and the tooth form of the positioning rack 81 adapts to that of the fixing tooth 821. Due to the large contacting area of the square teeth, the stress points are concentrated in a one point, so that the sliding block shell 21 can be fixed in a certain position of the stand column 1 stably.
The more the fixing tooth 821, the firm meshing between the fixing tooth 821 and the positioning rack 81. That is, the more stable the sliding block shell 21 fixing on the stand column 1, the stronger bearing capacity of the umbrella tent 4 installed on the cantilever 3. Preferentially, the number of the fixing tooth 821 is three, but not restricted to, two or four or five, which is not limited in the utility model. The utility model can limit the umbrella tent from rotating to a large elevation through the positioning part 5, so as to avoid tilting under the large external force. In addition, the positioning part 5 is simple in structure, convenient to install, firm and favorable for prolonging the service life of the umbrella.
