[0001] The invention relates to a fence support which can be conveniently and quickly placed and stored and a method for using the fence support. Background Art

[0002] At present, the fence supports on the market include pier type and umbrella type. Among them, the umbrella type is widely used in power construction because it can be folded and stored when not in use, which saves space and is convenient for carrying and placing. However, the existing umbrella type fence supports have some disadvantages during use. Because its closure and expansion rely on the up and down movement of the sliding sleeve on the support rod to achieve the closure and expansion of the support legs, the staff needs to manually press the collar downward to expand the support legs and pull the collar upward to close the support legs every time during use. In the process of pressing the collar downward to expand the support legs, because the support legs in the closed state are in a straight line with the connecting rod, a dead angle of force is formed, and they often cannot be smoothly opened outward, which causes certain difficulties in expansion, and it is still somewhat inconvenient and laborious to use. The above reasons combined make the current umbrella type fence supports inconvenient in use, and the efficiency of installation and storage is low. Summary of the invention

The spring element is arranged so that the connecting rod and the supporting legs always have an elastic force to close inward. When the inner tube is to be inserted inwardly into the supporting outer tube, the connecting rod and the supporting legs can be smoothly opened outward, avoiding the problem of jamming caused by the connecting rod and the supporting legs being in a straight line and forming a dead angle of force, which will cause the connecting rod and the supporting legs to be unable to open outward smoothly. By pressing the elastic ring relatively inward Hooks A and B of the body are used to form a gap between the elastic ring body and the supporting outer cylinder. The elastic ring body can move to any position along the length direction of the supporting outer cylinder. Loosen the hooks A and B of the elastic ring body, and tighten the elastic ring body and the supporting outer cylinder again. Hooks A and B are used to fix the fence rope. When the fence bracket needs to be stored, untie the fence rope on hooks A and B, directly lift the supporting outer cylinder upward, and the inner cylinder moves downward along the length direction of the supporting outer cylinder under the action of gravity, automatically moving downward, driving the connecting rod and the supporting feet to close inward, and the connecting rod and the supporting feet form a straight line, thereby completing the storage of the fence bracket, and then the fence bracket can be placed on the tool cart or in the tool room. In addition, in the storage state, if the side with the needle of the dual-purpose counterweight is outward, just unscrew it and screw the side with the needle inward into the inner cylinder to avoid sharp outwards that may cause injuries. The device increases the weight of the lower part by arranging an inner cylinder and supporting an outer cylinder, making it convenient to retract and release, and lowering the center of gravity, so that it is more stable after being placed.

DETAILED DESCRIPTION

[0016] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Example: Figure 1-7 As shown, a fence support that can be easily and quickly placed and stored is provided, including a supporting outer cylinder 1 and an inner cylinder 2 which is sleeved on the lower part of the supporting outer cylinder and can slide along the inner cavity of the supporting outer cylinder, the outer diameter of the inner cylinder is smaller than the outer diameter of the supporting outer cylinder, an outer cylinder connecting base 6 is installed on the outside of the supporting outer cylinder, an inner cylinder connecting base 5 is arranged at the bottom of the inner cylinder, a plurality of supporting feet 3 and a plurality of connecting rods 4 are arranged between the outer cylinder connecting base and the inner cylinder connecting base, the number of the connecting rods is the same as that of the supporting feet, one side of the supporting foot is hinged to the outer cylinder connecting base, the other side of the supporting foot is hinged to one side of the connecting rod, and the other side of the connecting rod is hinged to the inner cylinder connecting base.

[0018] In the embodiment of the present invention, in order to avoid the connecting rod and the supporting legs being in a straight line when the two are in a closed state, when the inner cylinder is to be inserted inward to support the outer cylinder after the bottom end of the inner cylinder touches the ground, sometimes the connecting rod and the supporting legs are in a straight line, forming a dead angle of force and causing jamming, which will make the connecting rod and the supporting legs unable to open outwards smoothly.

[0019] Therefore, an elastic element 8 is provided between the connection of the connecting rod and the supporting foot to assist the connecting rod and the supporting foot to not be in the same straight line in the closed state. The provided spring element makes the connecting rod and the supporting foot always have an elastic force to close inward. When the inner cylinder is to be inserted inward to support the outer cylinder, the connecting rod and the supporting foot can be smoothly opened outward. At the same time, the elastic force set by the spring element does not need to be too large, otherwise the connecting rod and the supporting foot will form a too large angle due to the action of the spring force when they are in the closed state, resulting in occupied space.

[0020] The elastic element mentioned above is a spring.

[0021] In the embodiment of the present invention, the outer cylinder connection base and the supporting foot are hinged via a connecting bolt A9, the supporting foot and the connecting rod are hinged via a connecting bolt B11, and the connecting rod and the inner cylinder connection base are hinged via a connecting bolt C10.

[0022] In the embodiment of the present invention, a dual-purpose counterweight block 7 is arranged below the inner cylinder connection base, and the upper and lower parts of the dual-purpose counterweight block are both threadedly connected to the lower part of the inner cylinder connection base.

[0023] One side of the dual-purpose counterweight block is flat, and the other side is provided with a fixing steel pin 13 .

[0024] A relief hole is arranged in the middle of the threaded hole, and the relief hole is communicated with the cavity of the inner cylinder.

[0025] When the ground is soil, the side of the dual-purpose counterweight with the fixed steel needle can be faced downward, and the side with the flat surface can be screwed into the bottom threaded hole of the inner tube for fixation. At this time, there is a fixed steel needle at the bottom of the fence bracket, which can be inserted into the ground to prevent it from being blown down by the wind; when the ground is hard, the side of the dual-purpose counterweight with the fixed steel needle can be screwed into the bottom threaded hole of the inner tube, and the fixed steel needle extends through the avoidance hole in the threaded hole to the cavity of the inner tube. The dual-purpose counterweight with the flat surface on the side contacts the hard bottom surface, increasing the bottom weight, and the fence bracket can be stably placed on the ground.

[0026] In an embodiment of the present invention, threaded columns are provided on the upper and lower parts of the dual-purpose counterweight block, a threaded hole is provided at the lower part of the inner tube connected to the base, and the threaded column is threadedly matched with the threaded hole; an external thread is provided on the outside of the threaded column, and an internal thread matching the external thread is provided on the inside of the threaded hole.

[0027] In the embodiment of the present invention, an adjustable spring buckle 12 is provided on the exterior.

[0028] The above-mentioned adjustable spring buckle includes an elastic ring body 123, one end of the elastic ring body extends beyond the other end of the elastic ring body, and one end of the elastic ring body is higher than the other end of the elastic ring body, and a dislocation space 124 is formed between the upper and lower ends of the elastic ring body. A hook A122 is provided at one end of the elastic ring body, and a hook B121 is provided at the other end of the elastic ring body. The hook A and hook B are used to hang the fence; the bending directions of the hook A and the hook B are opposite, the hook A is bent downward, and the hook B is bent upward.

[0029] The adjustable spring-type buckle forms a circle and tightly embraces the supporting outer tube to form a fixation; when the worker pinches hook A and hook B in the closing direction with his fingers, the spring of the adjustable spring-type buckle becomes loose, and the adjustable spring-type buckle can move up and down along the supporting outer tube. After adjusting to a suitable position for hanging the fence, the hook A and hook B are released, and the adjustable spring-type buckle can be fixed at the corresponding position of the supporting outer tube. This design allows the staff to conveniently adjust the height of the buckle at any time.

[0030] Hook A and hook B are a pair of hooks bent in opposite directions, hook A is bent downward, and hook B is bent upward. This design makes it easy for the rope body of the fence to be installed in the hooks A and B without falling off easily.

[0031] In the embodiment of the present invention, when in use: (1) when using the fence support, the inner tube of the fence support is connected to the base and placed on the ground, the inner tube slides relative to the supporting outer tube and moves to the inside of the supporting outer tube, and the supporting legs are driven to fully open through the connecting rod to form a stable support; the spring element is set so that the connecting rod and the supporting legs always have an elastic force to close inward, and when the inner tube is to be inserted into the supporting outer tube, the connecting rod and the supporting legs can be smoothly opened outward, avoiding the dead angle of force caused by the connecting rod and the supporting legs being in a straight line, which will cause the connecting rod and the supporting legs to be unable to open outward smoothly; (2) the hooks A and B of the elastic ring body are pressed inwardly, so that A gap is formed between the elastic ring body and the supporting outer cylinder. The elastic ring body can be moved to any position along the length direction of the supporting outer cylinder. The hooks A and B of the elastic ring body are loosened, and the elastic ring body and the supporting outer cylinder are tightened again. The hooks A and B are used to fix the fence rope; (3) When the fence bracket needs to be stored, the fence rope on the hooks A and B is untied, and the supporting outer cylinder is directly lifted upward. The inner cylinder moves downward along the length direction of the supporting outer cylinder under the action of gravity, and moves downward automatically, driving the connecting rod and the supporting feet to retract inward, and the connecting rod and the supporting feet form a straight line, thereby completing the storage of the fence bracket, and then the fence bracket can be placed on the tool cart or in the tool room. In addition, in the storage state, if the side with the needle of the dual-purpose counterweight is outward, just unscrew it and screw the side with the needle inward into the inner cylinder to avoid sharp outwards that may cause injury.

[0032] In an embodiment of the present invention, when in the storage state, the connecting rod and the supporting feet are retracted inward, and the inner cylinder moves downward along the supporting outer cylinder, but a small section of the inner cylinder is still inside the supporting outer cylinder, which will not cause the inner cylinder to escape from the supporting outer cylinder; for example, a positioning protrusion can be provided at the upper end of the inner cylinder, and a through hole through which the inner cylinder passes inward can be provided at the bottom of the supporting outer cylinder, and the diameter of the positioning protrusion is larger than the diameter of the through hole and the inner cylinder.
