DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0025] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0026] See also Figures 1 to 5 As shown, a corrosion-resistant triangular bracket includes a bracket body, the bracket body includes a large connecting plate 1, and three supporting feet 2 are rotatably connected to the side of the large connecting plate 1. Both ends of the supporting feet 2 are curved, and matching connecting grooves a are provided on the side of the large connecting plate 1 corresponding to the top of the supporting feet 2. The supporting feet 2 are rotatably connected to the large connecting plate 1 via the connecting groove a, and the bottom ends of the supporting feet 2 are provided with anti-slip foot covers 201.
[0027] According to the above scheme, the bracket body serves as the main structure of the triangular bracket of the utility model, and the anti-skid foot cover 201 provided at the bottom end of the supporting foot 2 can improve the anti-skid property and stability of the triangular bracket when it is deployed and supported.
[0028] like Figure 1 and Figure 2 An adjustment structure is provided at the bottom of the bracket body, and the adjustment structure includes a small connecting plate 3. Corresponding to the supporting foot 2, three adjustment rods 4 are rotatably connected on the side of the small connecting plate 3. The top end of the adjustment rod 4 is curved toward the side of the small connecting plate 3, and the bottom end is curved. Corresponding to the top end of the adjustment rod 4, a matching connection groove b301 is provided on the side of the small connecting plate 3. The adjustment rod 4 is rotatably connected to the small connecting plate 3 via the connection groove b301, and the other end of the adjustment rod 4 is rotatably connected to the corresponding side of the supporting foot 2.
[0029] According to the above scheme, the structural shape of the adjustment structure is in the same proportion as the structural shape of the bracket body (the structural size of the adjustment structure is reduced in the same proportion as the structural size of the bracket body), and the end of the adjustment rod 4 in the adjustment structure is rotatably connected to the side of the supporting foot 3, so that the adjustment structure can be driven to be synchronously expanded and collapsed with the expansion and collapse of the bracket body: when the bottom of the bracket body (three supporting feet 2) is expanded, the adjustment structure (three adjustment rods 4) at the bottom of the bracket body will be synchronously expanded with the expansion of the supporting feet 2; when the bottom of the bracket body (three supporting feet 2) is collapsed inward, the adjustment structure (three adjustment rods 4) at the bottom of the bracket body will be synchronously collapsed with the collapse of the supporting feet 2, and finally folded and collapsed inside the bracket body.
[0030] At the same time, the top of the adjusting rod 4 is arranged in a curved surface only toward one side of the small connecting plate 3, which can limit the maximum rotation angle of the adjusting rod 4 to 180°, so that the adjusting structure can be flattened at the bottom of the bracket body at a maximum expansion angle.
[0031] like Figures 3 to 5 The adjusting rod 4 includes a sleeve rod, the top end of the sleeve rod is rotatably connected to the small connecting plate 3, the bottom end of the sleeve rod is slidably connected to an inner slide rod 5, a matching slide groove is provided in the sleeve rod corresponding to the inner slide rod 5, a plurality of adjusting holes 502 are provided on the inner slide rod 5, a matching limiting screw hole 401 is provided on one side of the top of the sleeve rod corresponding to the adjusting holes 502, a fixing nut 7 is detachably connected between the adjusting hole 502 and the limiting screw hole 401, and a matching connecting screw hole 302 is provided on the small connecting plate 3 corresponding to the fixing nut 7.
[0032] like Figure 4 As shown, the fixing nut 7 includes a fixing rod, the length of the fixing rod = the length of the adjustment hole 502 + the length of the limiting screw hole 401, a rotating handle is provided at the top of the fixing rod, and a matching thread is provided at the top end side of the fixing rod corresponding to the limiting screw hole 401.
[0033] like Figure 5 As shown, the inner sliding rod 5 is provided with a connecting end 501 at one end facing the supporting foot 2, and a connecting seat 6 is provided on one side of the supporting foot 2 corresponding to the connecting end 501, and the connecting seat 6 includes two fixed plates 601, and the two fixed plates 601 are fixedly connected to one side of the supporting foot 2 at both sides corresponding to the connecting end 501, and a rotating shaft 602 is connected between the two fixed plates 601, and a matching rotating groove 5011 is provided on the connecting end 501 corresponding to the rotating shaft 602, and the connecting end 501 is rotatably connected to the supporting foot 2 via the connecting seat 6.
[0034] According to the above solution, the adjustment structure controls and adjusts the size of the unfolding range by rotating the adjustment rod 4 connected to the peripheral side of the small connecting plate 3.
[0035] When the support leg 2 is opened for expansion and support and needs to be fixed, it is necessary to screw and remove the (three) fixing nuts 7 screwed on the top of the small connecting plate 3, and screw the fixing nuts 7 again in the limiting screw holes 401 at the top of the sleeve rod in the adjusting rod 4. When screwing and fixing, the adjusting holes 502 (on the inner sliding rod 5) at the bottom of the corresponding limiting screw holes 401 can be selectively slidably adjusted. When a certain adjusting hole 502 (on the inner sliding rod 5) corresponds to the limiting screw hole 401 up and down, the fixing nut 7 is used to insert and connect the two (the limiting screw hole 401 and the certain adjusting hole 502), and the fixing nut 7 is screwed and fixed between the two (the limiting screw hole 401 and the certain adjusting hole 502) through the thread on the top side of the fixing rod to fix the use length of the adjusting rod 4. After the use lengths of the three adjusting rods 4 are matched and adjusted, the support body can be stably and fixedly supported for expansion via the adjusting rod 4.
[0036] The surfaces of the bracket body and the adjustment structure are sprayed with a corrosion-resistant coating, and the spraying of the corrosion-resistant coating can effectively improve the corrosion resistance of the triangular bracket of the utility model.
[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
