Description

Technical Field

[0001] The invention relates to the technical field of clamps, and in particular to a gravity-type adaptive clamp. Background Art

[0002] With the development of the city, the demand for road poles is becoming increasingly obvious; the demand for temporary addition of monitoring facilities, lighting facilities, etc. is also becoming increasingly apparent.

[0003] In the prior art, the equipment in the above-mentioned monitoring facilities and lighting facilities are usually fixed on the enclosed objects (tree trunks, road poles, etc.) by using clamps, and conventional clamps usually have relatively fixed sizes corresponding to enclosed objects of fixed sizes. Square clamps can only be installed on square enclosed objects of fixed sizes, and round clamps can only be installed on round enclosed objects of fixed sizes. The size of the clamps cannot be adjusted and cannot adapt to enclosed objects of different sizes, and the versatility is poor. Especially when the clamps are installed on growing tree trunks, it will affect the growth of plants. In the long run, the clamps will cause damage to the bark of the plants and affect the survival of the plants.

[0004] Moreover, conventional clamps use fasteners such as bolts and screws to fix the clamp structures and the clamps to the enclosed objects, which is not convenient for disassembly and assembly; especially after the installed clamps have been exposed to the sun and rain for a long time, the fasteners of the clamps will produce a certain amount of rust, which will further cause certain damage and trouble to the disassembly, making it inconvenient for the maintenance work of disassembly and assembly of the clamps at a later stage.

[0005] Therefore, technicians in this technical field are committed to developing a gravity-type adaptive clamp to facilitate disassembly while being able to adapt to enclosed objects of different sizes. Summary of the invention

[0006] In view of the above-mentioned defects of the prior art, the technical purpose of the present invention is to provide a gravity-type adaptive clamp to solve the problems that the existing clamp has poor versatility and is inconvenient to disassemble and assemble.

[0007] In order to achieve the above technical objectives, the present invention provides a gravity-type adaptive clamp, comprising a fixed structure, on which at least three unequal-diameter sector pieces are arranged;

[0008] The radius of each of the unequal diameter sector pieces gradually changes from the minimum radius r to the maximum radius R from top to bottom; the radius change trajectory of each of the unequal diameter sector pieces forms a respective arc portion;

[0009] Each of the unequal diameter sector pieces is provided with a pivoting component at the intersection of the minimum radius r and the maximum radius R; each of the unequal diameter sector pieces is rotatably arranged on the inner side of the fixed structure through the pivoting component;

[0010] When the fixed structure is sleeved from top to bottom on the periphery of the enclosed object, the initial friction force between the arc-shaped portion and the outer wall of the enclosed object is used to cause each of the unequal-diameter sector-shaped pieces to rotate counterclockwise to gradually increase the working radius of the unequal-diameter sector-shaped pieces, until the final friction force between each of the arc-shaped portions and the outer wall of the enclosed object is sufficient to support the deadweight of the gravity-type adaptive clamp, so that the gravity-type adaptive clamp automatically adapts to the outer diameter of the enclosed object and is fixed on the periphery of the enclosed object.

[0011] Preferably, the pivotal component comprises a pivot rotatably arranged on the fixed structure, and the pivot is fixedly arranged at the intersection of the minimum radius r and the maximum radius R on the unequal diameter sector-shaped piece.

[0012] Preferably, the fixing structure is provided with openings for passing through each pivot at two end positions corresponding to each pivot; and each of the unequal diameter sector pieces is also provided with openings for passing through each pivot at the intersection of the minimum radius r and the maximum radius R.

[0013] Preferably, the plurality of unequal diameter sector-shaped pieces are arranged at equal intervals.

[0014] Preferably, each of the unequal diameter sector-shaped pieces is provided with wing plates on the outer sides of each of the arc-shaped portions, which are consistent with the curvature of each of the arc-shaped portions and extend laterally to both sides of each of the unequal diameter sector-shaped pieces.

[0015] Beneficial effects of the present invention:

[0016] Due to the above-mentioned structural design, the present invention has a rotatable unequal diameter fan-shaped piece, which can fall by its own gravity and finally be fixed on the enclosed object when it is sleeved from top to bottom on the periphery of the enclosed object of different sizes and shapes. It has stronger versatility. When used on plant branches, the clamping tightness of the unequal diameter fan-shaped piece on the tree trunk can also be regularly adjusted to reduce the impact on the growth of the plant branches.

[0017] The unequal diameter sector pieces connected by the pivotal parts can be easily disassembled and assembled, thereby facilitating maintenance work on the later disassembly and assembly of the unequal diameter sector pieces. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.

[0024] Example:

[0025] like Figure 1-Figure 4 As shown, a gravity-type adaptive clamp comprises a square ring-shaped fixed structure 1, on which four unequal-diameter sector pieces 2 arranged at equal intervals are arranged;

[0026] The radius of each unequal-diameter sector piece 2 gradually changes from the minimum radius r to the maximum radius R from top to bottom; the radius change trajectory of each unequal-diameter sector piece 2 forms a respective arc portion;

[0027] Each unequal diameter sector-shaped piece 2 is provided with a pivoting component at the intersection of the minimum radius r and the maximum radius R; each unequal diameter sector-shaped piece 2 is rotatably arranged on the inner side of the fixed structure 1 through the pivoting component.

[0028] In other embodiments, according to actual needs, each clamp may include three, six, or other positive integer number of sector-shaped pieces of unequal diameters.

[0029] According to the specific construction environment, the spacing between the unequal diameter sector pieces can also be adaptively adjusted and is not strictly limited to equal spacing.

[0030] The main innovation of the present invention is that the gravity-type adaptive clamp can automatically adapt to the outer diameter or shape of the enclosed object and be fixed on the outer surface of the enclosed object by its own gravity without external force or manual adjustment. The requirements for the shape of the enclosed object are greatly reduced, which greatly expands the applicability of the present invention.

[0031] More specifically, when the fixing structure 1 is sleeved from top to bottom on the periphery of the enclosed object 3, the initial friction force between the arc-shaped portion on the unequal-diameter sector-shaped piece 2 and the outer wall of the enclosed object 3 is used to cause each unequal-diameter sector-shaped piece 2 to rotate counterclockwise to gradually increase the working radius of the unequal-diameter sector-shaped piece 2, until the final friction force between each arc-shaped portion and the outer wall of the enclosed object 3 is sufficient to support the deadweight of the gravity-type adaptive clamp, so that the gravity-type adaptive clamp automatically adapts to the outer diameter of the enclosed object 3 and is fixed on the periphery of the enclosed object 3.

[0032] Furthermore, in order to facilitate the disassembly and assembly of the unequal diameter sector piece 2 and the pivot 4, the pivot component includes a pivot 4 rotatably arranged on the fixed structure 1, and the pivot 4 is fixedly arranged at the intersection of the minimum radius r and the maximum radius R on the unequal diameter sector piece 2.

[0033] The pivot 4 can be fixed to the unequal diameter sector piece 2 as a whole.

[0034] In some other embodiments, the pivot 4 can also be inserted into the through hole on the unequal diameter sector piece 2, and is not fixed as a whole. Specifically, at the two ends of the fixed structure 1 corresponding to each pivot 4, openings for inserting each pivot 4 are respectively opened; each unequal diameter sector piece 2 is also respectively opened at the intersection of the minimum radius r and the maximum radius R for inserting each pivot 4; the fixed structure 1 and the unequal diameter sector piece 2 can be pre-reserved with openings in advance during prefabrication, and when the unequal diameter sector piece 2 is installed, the opening of the unequal diameter sector piece 2 is first matched with the two openings of the fixed structure, and then a pivot 4 is inserted into the three openings, so that the unequal diameter sector piece 2 can be rotatably fixedly installed relative to the fixed structure.

[0035] When disassembling the unequal diameter sector pieces 2, it is only necessary to pull out the corresponding pivot 4; thus, it is more convenient to replace the unequal diameter sector pieces 2 of different specifications to adapt to the enclosed objects 3 of different sizes, and to replace the individually damaged unequal diameter sector pieces 2.

[0036] In this embodiment, the unequal diameter sector-shaped pieces 2 are formed by a quarter of an elliptical block, but are not limited to a quarter of an elliptical block.

[0037] In some embodiments, the fixing structure 1 may be any polygonal frame. The shape of the fixing structure is not limited to a square ring, but may also be a circular ring, a polygon, or other applicable shapes.

[0038] In other embodiments, in order to increase the friction between the unequal diameter sector pieces 2 and the enclosed object 3, each unequal diameter sector piece 2 is provided with wing plates 5 on the outer side of each arc portion, which are consistent with the curvature of each arc portion and extend laterally to both sides of each unequal diameter sector piece 2.

[0039] The working principle and use process of the present invention:

[0040] When fixing, first fix the equipment 6 to be installed on the fixed structure 1, and then put the fixed structure 1 on the outer periphery of the enclosed object 3 from top to bottom. After the arc-shaped portion of each unequal diameter sector-shaped piece 2 contacts the enclosed object 3, under the action of friction, each unequal diameter sector-shaped piece 2 rotates counterclockwise gradually from the minimum radius r to the maximum radius R, until the friction between each arc-shaped portion and the enclosed object 3 is sufficient to support the dead weight of the gravity-type adaptive clamp and the equipment 6, and the gravity-type adaptive clamp and the enclosed object 3 are locked with each other.

[0041] During disassembly, it is only necessary to apply a reverse force below the fixed structure 1, that is, to push the fixed structure 1 upward, so that each unequal diameter sector piece 2 rotates clockwise and each unequal diameter sector piece 2 gradually changes from the maximum radius R to the minimum radius r, until the gravity-type adaptive clamp and the enclosed object 3 are separated.

[0042] In particular, when the gravity-type adaptive clamp is fixed on the tree trunk, in order to avoid the unequal-diameter sector-shaped pieces 2 from clamping the outer periphery of the trunk too tightly and restricting the normal growth of the trunk; the disassembly process of the above-mentioned gravity-type adaptive clamp can be referred to to adjust the clamping tightness of the unequal-diameter sector-shaped pieces 2. Unlike the disassembly process, there is no need to adjust the gravity-type adaptive clamp and the enclosed object 3 to separate. It is only necessary to slightly push the fixed structure 1 upward for a certain distance to ensure that the unequal-diameter sector-shaped pieces 2 do not clamp the trunk too tightly and at the same time ensure that the gravity-type adaptive clamp is firmly fixed; by regularly adjusting the gravity-type adaptive clamp, the impact on the plant branches and trunks at the clamp is reduced.

[0043] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
