Description

Technical Field

[0001] The present invention relates to the technical field of safety work fences, in particular to a field work fence with a base folding and detaching function. Background Art

[0002] Before power technicians begin maintenance work, they typically install safety fences to isolate the equipment being repaired from live equipment. They also hang an appropriate number of "Stop, High Voltage Danger" signs to prevent workers from accidentally entering live compartments and risking personal injury. Safety fences define the work area for maintenance personnel during maintenance work and safeguard their personal safety. The stability and compliance of safety fence installation are directly related to the safety of maintenance personnel.

[0003] The existing safety work fence has the following problems during use:

[0004] First, the fences take up a lot of space when stacked during transportation, which is inconvenient to transport and carry; and the base of the safety fence currently used is an integrated structure with the fence, which makes it easy for the fence and the base to cross each other, causing the fences to be entangled with each other. During on-site work, it is easy to damage the fences in order to dismantle the entangled fences.

[0005] Second, fences are prone to collapse in windy weather, and workers are prone to committing violations such as crossing over fences when tidying them. Summary of the Invention

[0006] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide a field work fence with a base folding and detaching function. After the folding hinge is folded, the column and the base can be changed from a vertical state to a parallel state, reducing the space occupied by the fence during transportation, and the fence and the base will not be cross-entangled with each other; the detachable connection between the column and the fixing sleeve makes it possible to replace the base of different lengths, thereby solving the problem of the fence easily tipping over in windy weather.

[0007] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0008] A field work fence with a foldable and detachable base comprises a fence connecting rod and a base, wherein both ends of the fence connecting rod are hinged to a column; a folding hinge is provided at the top of the base, the outer side surface of the movable end of the folding hinge is connected to a fixed sleeve, and the bottom end of the column is used to be inserted into the fixed sleeve to achieve a detachable connection with the fixed sleeve.

[0009] As a further implementation method, the folding hinge is a 90° folding hinge, which has a fixed end and a movable end that rotate with each other. The outer side surface of the fixed end is fixedly connected to the top surface of the base. After the movable end is unfolded, it can be relatively locked with the fixed end, and the outer side surface of the movable end is perpendicular to the top surface of the base.

[0010] As a further implementation, the cross-sectional shape of the fixing sleeve is adapted to the cross-sectional shape of the bottom end of the column.

[0011] As a further implementation, a set of opposite side surfaces of the fixing sleeve are provided with through holes, and a limiting member is slidably provided at the through holes, and the front end of the limiting member is used to extend into the through holes and lock the bottom end of the column.

[0012] As a further implementation method, the limiting member includes a limiting plate and a limiting pin, the limiting pin is vertically connected to the limiting plate, the limiting plate is located on the outside of the fixed sleeve, the limiting pin extends through the through hole to the inside of the fixed sleeve, the inner side of the limiting plate and the outer side of the fixed sleeve are connected by a spring, and the spring is sleeved on the limiting pin.

[0013] As a further implementation method, when the spring is in a natural state, the front end of the limit pin is located inside the fixing sleeve, and the bottom end of the column is correspondingly provided with a fixing hole that cooperates with the limit pin.

[0014] As a further implementation method, the column includes a first column and a second column at both ends of the fence connecting rod, and the bottom ends of the first column and the second column are both matched with the fixing sleeve.

[0015] As a further implementation method, the first column is hollow, and a through hole is provided on the side wall. A chain is provided at the through hole, and the chain is used for tying the working fence after it is folded up.

[0016] As a further implementation method, one end of the chain is connected to a limit ring and the other end is connected to a lock buckle. The outer diameter of the limit ring is larger than the outer diameter of the through hole, and the limit ring is located inside the column; the lock buckle is larger than the through hole and is located outside the column, and a U-shaped plate is provided on the outside of the base.

[0017] As a further implementation, a lug plate is provided in the middle of the column, the through hole is located in the middle of the column, and the lock buckle is used to bypass the second column and lock with the lug plate.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The two ends of the fence connecting rod of the present invention are hinged to the column; a folding hinge is provided on the top of the base, the outer side surface of the movable end of the folding hinge is connected to the fixing sleeve, and the bottom end of the column is used to be inserted into the fixing sleeve to achieve a detachable connection with the fixing sleeve.

[0030] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0031] Example 1

[0032] In a typical embodiment of the present invention, referring to Figure 1-Figure 5 As shown, a field work fence with a base folding and detaching function includes a fence connecting rod 5 and a base 3, and both ends of the fence connecting rod 5 are hinged to the column; a folding hinge is provided on the top of the base 3, and the outer side surface of the movable end of the folding hinge 8 is connected to the fixed sleeve 4, and the bottom end of the column is used to be inserted into the fixed sleeve 4 to achieve a detachable connection with the fixed sleeve 4.

[0033] like Figure 1 As shown, each group of posts of the on-site work fence includes a first post 1 and a second post 2. The fence connecting rod 5 is the existing technology, and its two ends are hinged to the first post 1 and the second post 2 respectively. By changing the distance between the first post 1 and the second post 2, the fence connecting rod 5 can be extended and contracted, thereby realizing the adjustment of the length of the working fence.

[0034] The bottom ends of the first column 1 and the second column 2 are detachably connected to the base 3. When transportation is required, the base 3 can be removed from the column for easy transportation.

[0035] like Figure 1 and Figure 2 As shown, a folding hinge is provided in the middle position of the top of the base 3, and the outer side surface of the movable end of the folding hinge 8 is connected to the fixed sleeve 4. Specifically, the folding hinge 8 is a 90° folding hinge, which has a fixed end and a movable end 81 that rotate with each other. The movable end 81 can rotate relative to the fixed end. When the rotation angle is 90°, the fixed end and the movable end can be locked by the locking structure of the folding hinge 8. When unlocking is required, the folding hinge 8 can be unlocked by pressing the corresponding unlocking part.

[0036] In this embodiment, the outer side surface of the fixed end is fixedly connected to the top surface of the base 3, and the movable end 81 can be relatively locked with the fixed end after being unfolded, and the outer side surface of the movable end 81 is perpendicular to the top surface of the base.

[0037] like Figure 2 The figure shows the extended state of the movable end 81 when it is rotated 90 degrees relative to the fixed end. At this time, the fixed end and the movable end are locked. The outer side of the movable end 81 is connected to the fixed sleeve 4. The fixed sleeve 4 has an open top and a hollow interior. The opening is facing upward, which facilitates the insertion of the bottom end of the column into the fixed sleeve 4.

[0038] In order to achieve a good fit between the fixing sleeve 4 and the bottom end of the column, the cross-sectional shape of the fixing sleeve 4 is adapted to the cross-sectional shape of the bottom end of the column, both are rectangular, and the sizes are adapted.

[0039] like Figure 3As shown, after the folding hinge 8 is folded, the first column 1 and the base 3 change from the original vertical state to a parallel state. After the folding hinge is folded, the volume occupied by the column and the base 3 during transportation can be reduced, and the fence and the base will not cross and entangle with each other, making transportation convenient.

[0040] A pair of opposite side surfaces of the fixed sleeve 4 are provided with through holes, and a limiter is slidably provided at the through holes. The front end of the limiter is used to extend into the through holes and lock the bottom end of the column. The two ends of the side surface connected to the movable end of the fixed sleeve 4 are connected to the side surface provided with the through holes.

[0041] like Figure 4 As shown, the limiting member includes a limiting plate 41 and a limiting pin 42. The limiting pin 42 is vertically connected to the limiting plate 41. The limiting plate 41 is located outside the fixing sleeve 4. The limiting pin 42 extends through the through hole into the fixing sleeve 4. The inner side of the limiting plate 41 and the outer side of the fixing sleeve 4 are connected by a spring 43, which is sleeved on the limiting pin 42. When the spring 43 is in the natural state, the front end of the limiting pin 42 is located inside the fixing sleeve 4. The bottom ends of the first column 1 and the second column 2 are correspondingly provided with fixing holes that cooperate with the limiting pin 42.

[0042] When it is necessary to install a work fence, the limit pin 42 is pulled outward through the limit plate 41, so that the front end of the limit pin 42 slides along the through hole and exits the interior of the solid sleeve 4, and the spring 43 is stretched. Then, the bottom end of the column is inserted into the fixed sleeve 4, and the limit pin 42 and the fixed hole are aligned. The limit plate 41 is loosened, and under the action of the spring, the front end of the limit pin 42 is inserted into the fixed hole, thereby realizing the locking of the fixed sleeve on the column.

[0043] When disassembly is required, the post can be separated from the base 3 by pulling out the limit pin 42. The detachable connection between the post and the base 3 allows for flexible transportation. The folding hinge can be folded or the base 3 can be removed, which reduces the space required for transportation and prevents the fence post and base 3 from becoming entangled with each other. When not in use, the base and post can be folded into a compact state, which greatly reduces the space occupied.

[0044] The detachable connection between the uprights and the base 3 allows for replacement of bases of different lengths. In windy weather, a longer base can be replaced to improve the stability of the fence and prevent it from being blown down. It can also be quickly assembled according to actual needs, using a weighted base to prevent the fence from toppling over and causing violations in windy weather.

[0045] In other examples, reflective strips are attached to the posts to improve nighttime visibility, with the words "Stop, High Voltage Danger" printed on them. All fencing materials are insulated and treated with anti-corrosion treatments to ensure long-term use in harsh outdoor environments without damage.

[0046] In order to facilitate transportation after the fence is folded up, Figure 1 and Figure 2 As shown, the first column is hollow, and a through hole 6 is provided on the side wall. A chain 7 is provided at the through hole 6. The chain 7 is used to tie up the working fence after the working fence is folded up.

[0047] like Figure 2 As shown, one end of the chain 7 is connected to a limiting ring 71 and the other end is connected to a lock buckle 72. The outer diameter of the limiting ring 71 is larger than the outer diameter of the through hole 6, and the limiting ring 71 is located inside the column; the size of the lock buckle 72 is larger than the through hole 6, and the lock buckle 72 is located outside the column.

[0048] An ear plate 73 is provided in the middle of the outer side of the column, the through hole 6 is located in the middle of the column, the ear plate 73 and the through hole 6 are located on opposite sides of the first column 1, and the lock buckle is used to bypass the second column 2 and lock with the ear plate.

[0049] When the fence is folded up, the first and second posts 1 and 2 are pushed toward each other, causing the fence link 5 to retract and bring the first and second posts 1 and 2 closer together. The chain 7 is then pulled outward using the lock buckle. The chain 7 passes around the second post and engages with the locking hole on the ear plate 73, thereby folding the entire fence together. When transporting the fence, one can lift a group of fences by simply holding the chain, making it easy to carry.

[0050] In a preferred example, Figure 5 As shown, a U-shaped plate 9 is provided in the middle position of the outer side of the base 3, with the opening of the U-shaped plate facing outward, and the ground of the U-shaped plate 9 is flush with the base. On the one hand, the U-shaped plate 9 can play a supporting role and serve as the supporting base of the fence together with the base 3 to improve the supporting strength of the fence. On the other hand, after the base and the column are disassembled, the base 3 is set parallel to the column, and the chain is passed around the U-shaped plate 9 to tie the two groups of columns and the two groups of bases 3 together. The length of the chain is determined according to the specific size requirements, so that after the chain passes around the U-shaped plate 9 to tie and fix the fence, when the chain is lifted, the chain will not detach from the opening of the U-shaped plate 9. In this way, all the structures of the fence can be tied together, which is convenient for transportation and can also be quickly assembled.

[0051] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
