Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction protection devices, in particular to a telescopic fence. Background Art

[0002] Retractable fence is a kind of fence that is retractable and suitable for public places with many people. It is flexible and convenient to deploy and is widely used in public places.

[0003] For example, the Chinese utility model patent with publication number CN220014730U provides an insulated telescopic fence, including a fence frame and a telescopic bar. The fence frame includes a first fence frame and a second fence frame. An intermediate post is provided between the first fence frame and the second fence frame. A first telescopic bar is installed between the first fence frame and the intermediate post. A second telescopic bar is installed between the second fence frame and the intermediate post. One end of the first telescopic bar is connected to the first fence frame, and the other end is connected to a first connecting member and a fourth connecting member sleeved on the intermediate post; one end of the second telescopic bar is connected to the second fence frame, and the other end is connected to a second connecting member and a third connecting member sleeved on the intermediate post. The utility model uses the first connecting member, the second connecting member, the third connecting member and the fourth connecting member to enable the fence to achieve a 0°-180° turning and changing direction during use. The fence frame and the intermediate post are filled with cement or insulating board, which can improve the overall wind resistance of the fence.

[0004] However, the first fence frame and the second fence frame in the above patent are fixedly connected to the base. When more fences are needed, a transport device is needed to carry them. Since the first fence and the second fence are fixedly connected on the base, the fence has an inverted T-shaped structure, and there will be large gaps between the multiple fences when they are placed, which takes up a large space of the transport device, reduces the space utilization of the transport device, and increases the cost of transportation. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a telescopic fence. By releasing the card plate (the card plate has a certain elasticity) on the sliding sleeve from the card slot, the first rotating plate can be connected by a hinge and refolded to be parallel to the length direction of the column, and the second rotating plate is rotated again to be parallel to the first rotating plate through the rotating shaft, and then the sliding sleeve is pulled upward to realize that the entire first rotating plate and the second rotating plate are completely on one side of the column, so that the entire device can be rotated and folded into a long strip.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The top end of the lifting link is installed in the lifting link, and the extension socket is installed in the lifting link, and the extension socket is provided with a new type of post.

[0008] Preferably, the clockwork spring is a coil spring, which is sleeved on the top end of the rotating rod, with one end inside the coil spring connected to the rotating rod and one end outside the coil spring connected to the inner wall of the housing.

[0009] Preferably, the shell is detachably connected to the top of the column, and the two ends of the coil spring are detachably connected to the rotating rod and the inner wall of the shell respectively.

[0010] Preferably, grooves are provided at the bottom end of the cavity and the top end of the shell, and both ends of the rotating rod are respectively installed in the corresponding grooves, and the pull rod is detachably connected to the end of the isolation belt.

[0011] Preferably, the surface array of the isolation belt is provided with ventilation holes, and the isolation belt is made of high-strength polyester material.

[0012] Preferably, threaded holes with the same tooth specifications are provided on the support blocks at the bottom of both ends of the first rotating plate and the second rotating plate. When the first rotating plate and the second rotating plate overlap, the threaded holes at their bottoms can overlap, and a threaded rod is installed in the threaded hole on the support block at the bottom of the first rotating plate.

[0013] Preferably, a limiting protrusion is provided at the bottom end of the column, and the sliding sleeve is sleeved on the column between the limiting protrusion and the limiting hook.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model has a simple structure. The operator takes out the pull rod from the limit hook on the adjacent telescopic fence. Under the action of the spring inside the shell, the rotating rod itself can be driven to rotate, ensuring that the pulled out isolation belt is re-entered into the cavity and re-wound on the rotating rod. Then the operator releases the card plate (the card plate has a certain elasticity) on the sliding sleeve from the card slot. The first rotating plate can be connected by a hinge and folded back to be parallel to the length direction of the column, and the second rotating plate is rotated back to be parallel to the first rotating plate through the rotating shaft. Then the sliding sleeve is pulled upward to realize that the entire first rotating plate and the second rotating plate are completely on one side of the column (the length of the first rotating plate is less than the length of the column), so that the entire device can be rotated and folded into a long strip, which is convenient for reducing the space occupancy rate of the transportation of the device and reducing the transportation cost of the device.

[0016] 2. The device can be easily exposed by removing the housing from the top of the column, and the top of the coil spring and the rotating rod can be removed from the housing and the rotating rod for replacement, which is convenient for quick maintenance of the device and ensures the service life of the device.

[0017] 3. This device is equipped with ventilation holes on the isolation belt to ensure that wind can pass through the isolation belt freely, thus preventing the entire device from being blown by the wind and causing the isolation belt to fall over, and effectively preventing the device from being damaged by bumps. The isolation belt made of high-strength polyester can ensure that it can be stretched multiple times without deformation, thereby increasing the service life of the device.

[0018] 4. This device can fix the second rotating plate to the bottom of the first rotating plate by rotating the threaded rod on the support block at the bottom of the first rotating plate, so as to prevent the second rotating plate from rotating freely at the bottom of the first rotating plate due to the rotating shaft when transporting the device, thereby ensuring the stability between the first rotating plate and the second rotating plate.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] A telescopic fence, the structure of which is as follows Figure 1-Figure 4 As shown, it includes a column 1, the upper part of the column 1 has a cavity 2, the column 1 has an opening on one side of the cavity 2, a rotating rod 5 is installed in the cavity 2, an isolation belt 6 is wrapped around the rotating rod 5, one end of the isolation belt 6 is passed through the opening, and a pull rod 8 is installed on the end of the isolation belt 6 passing through the opening, the column 1 has a limit hook 10 on the other side of the cavity 2, a shell 3 is installed on the top of the column 1, the rotating rod 5 is deeply set in the shell 3, and a connecting rod 10 connected to the rotating rod 5 is provided in the shell 3. A clockwork spring, a sliding sleeve 9 is provided on the lower end of the column 1, a first rotating plate 14 is installed on one side of the sliding sleeve 9 through a hinge 11, and a clamping plate 13 is provided on the other side of the sliding sleeve 9, and a clamping groove 12 is provided on the first rotating plate 14 to cooperate with the clamping plate 13, and a second rotating plate 16 is installed on the bottom of the first rotating plate 14 through a rotating shaft 15, and the length of the second rotating plate 16 is smaller than the first rotating plate 14, and support blocks that can abut against the ground are installed on both sides of the bottom of the first rotating plate 14 and the second rotating plate 16.

[0027] When the telescopic fence needs to be used, multiple telescopic fences are taken out in turn, and then the sliding sleeve 9 on each telescopic fence is slid from the middle of the column 1 to the bottom end of the column 1 until the sliding sleeve 9 slides to the bottom end of the column 1. Since the first rotating plate 14 is connected to the side of the sliding sleeve 9 by the hinge 11, the operator can rotate the first rotating plate 14 from the state of abutting the side of the sliding sleeve 9 to abutting the sliding sleeve 9 and the bottom end of the column 1, ensuring that the first rotating plate 14 is changed from the original state of being parallel to the column 1 to being perpendicular to the column 1, so that the first rotating plate 14 and the column 1 form a T-shaped structure. Since a card plate 13 is provided on the side opposite to the sliding sleeve 9 and the hinge 11, and a card slot 12 adapted to the card plate 13 is provided on the top of the first rotating plate 14, when the first rotating plate 14 is rotated to be perpendicular to the column 1, the card plate 1 on the sliding sleeve 9 3 can be inserted into the slot 12 at the upper end of the first rotating plate 14 to ensure that the first rotating plate 14 is fixed to the bottom end of the column 1, and then the second rotating plate 16 is rotated to form a cross-shaped structure with the first rotating plate 14. Since the length of the first rotating plate 14 is greater than that of the second rotating plate 16, the support blocks at the bottom of both ends of the first rotating plate 14 and the second rotating plate 16 can be abutted against the ground, ensuring that the column 1 can be placed vertically on the ground. Then the operator places multiple telescopic fences at a certain distance, and by pulling the pull rod 8, the isolation belt 6 can be pulled out from the inside of the cavity 2. Then the pull rod 8 is clamped in the limit hook 10 on another nearby telescopic fence. By combining multiple telescopic fences, the power construction area can be isolated from the outside, preventing outsiders from entering the construction area.

[0028] When the construction is completed and the device needs to be transported to another place, the operator takes out the pull rod 8 from the limit hook 10 on the adjacent telescopic fence. Under the action of the spring inside the shell 3, the rotating rod 5 can be driven to rotate itself, ensuring that the pulled out isolation belt 6 is re-entered into the cavity 2 and re-wound around the rotating rod 5. Then the operator releases the card plate 13 (the card plate 13 has a certain elasticity) on the sliding sleeve 9 from the card slot 12, and the first rotating plate 14 can be connected by the hinge 11 and folded back to be parallel to the length direction of the column 1, and the second rotating plate 16 is rotated back to be parallel to the first rotating plate 14 through the rotating shaft 15. Then the sliding sleeve 9 is pulled upward to achieve the entire first rotating plate 14 and the second rotating plate 16 being completely on one side of the column 1 (the length of the first rotating plate 14 is less than the length of the column 1), so that the entire device can be rotated and folded into a long strip, which is convenient for reducing the space occupancy rate of the transportation of the device and reducing the transportation cost of the device.

[0029] The winding spring is a coil spring 4 , which is sleeved on the top of the rotating rod 5 . One end of the coil spring 4 is connected to the rotating rod 5 , and one end of the coil spring 4 is connected to the inner wall of the housing 3 .

[0030] Since one end inside the coil spring 4 is connected to the rotating rod 5 and the other end outside the coil spring 4 is connected to the shell 3, when the isolation belt 6 is pulled outward by the pull rod 8, the rotating rod 5 can be rotated, and when the rotating rod 5 rotates, it drives the coil spring 4 at its top to be reeled. When the isolation belt 6 needs to be re-entered into the cavity 2, by releasing the pull rod 8, the rotating rod 5 can be driven to rotate in the opposite direction under the force generated by the reset of the coil spring 4, and the isolation belt 6 is reeled, ensuring that the isolation belt 6 can be completely received into the space and wound around the rotating rod 5, thereby realizing automatic reeling of the isolation belt 6.

[0031] The housing 3 is detachably connected to the top of the column 1 , and both ends of the coil spring 4 are detachably connected to the rotating rod 5 and the inner wall of the housing 3 .

[0032] When the coil spring 4 fails, the housing 3 is removed from the top of the column 1 to expose the top of the coil spring 4 and the rotating rod 5. The coil spring 4 can then be removed from the housing 3 and the rotating rod 5 for replacement, making it easy to quickly repair the device and ensure its service life.

[0033] The surface array of the isolation belt 6 is provided with ventilation holes 7, and the isolation belt 6 is made of high-strength polyester material.

[0034] When the device is used in an external environment, in the case of wind, the ventilation holes 7 are provided to ensure that the wind can pass freely through the isolation belt 6, thereby preventing the entire device from being blown by the wind and causing the isolation belt 6 to fall over, and effectively preventing the device from being damaged by bumps. The isolation belt 6 made of high-strength polyester can ensure that it can be stretched multiple times without deformation, thereby increasing the service life of the device.

[0035] The support blocks at the bottom of both ends of the first rotating plate 14 and the second rotating plate 16 are provided with threaded holes 17 with the same tooth specifications. When the first rotating plate 14 and the second rotating plate 16 overlap, the threaded holes 17 at their bottoms can overlap. A threaded rod 18 is installed in the threaded hole 17 on the support block at the bottom of the first rotating plate 14.

[0036] Since the middle part of the first rotating plate 14 is connected to the middle part of the second rotating plate 16 by the rotating shaft 15, when the device needs to be folded up, the second rotating plate 16 is rotated to transform it and the first rotating plate 14 from a cross-shaped structure into a long strip structure that overlaps. At this time, the threaded hole 17 on the bottom support block of the second rotating plate 16 coincides with the threaded hole 17 on the bottom support block of the first rotating plate 14. By rotating the threaded rod 18 on the bottom support block of the first rotating plate 14, the second rotating plate 16 can be fixed to the bottom of the first rotating plate 14, thereby preventing the second rotating plate 16 from rotating freely at the bottom of the first rotating plate 14 due to the rotating shaft 15 when transporting the device, thereby ensuring the stability between the first rotating plate 14 and the second rotating plate 16.

[0037] A limiting protrusion is provided at the bottom end of the column 1 , and the sliding sleeve 9 is sleeved on the column 1 between the limiting protrusion and the limiting hook 10 .

[0038] Since the sliding sleeve 9 can slide up and down on the column 1, in order to prevent the sliding sleeve 9 from falling off the column 1, a limiting protrusion is provided at the bottom of the column 1. When the sliding sleeve 9 slides to the bottom end of the column 1, it can prevent the sliding sleeve 9 from falling off from the bottom end of the column 1, but it will not prevent the first rotating plate 14 from abutting against the bottom end of the column 1 and the bottom end of the sliding sleeve 9. The limiting hook 10 on the column 1 can prevent the sliding sleeve 9 from falling off from the upper end of the column 1.

[0039] Example 2

[0040] Based on the first embodiment, grooves are provided at the bottom of the cavity 2 and the top of the shell 3, and the two ends of the rotating rod 5 are respectively installed in the corresponding grooves, and the pull rod 8 is detachably connected to the end of the isolation belt 6.

[0041] Since grooves are provided at the bottom of the cavity 2 and the top of the shell 3, and the two ends of the rotating rod 5 are respectively installed in the corresponding grooves, when the operator pulls the pull rod 8, the rotating rod 5 can be driven to rotate in the upper and lower grooves through the isolation belt 6. When the isolation belt 6 needs to be replaced, the shell 3 and the pull rod 8 can be disassembled separately, so that the operator can directly take out the rotating rod 5 wrapped with the isolation belt 6 for replacement. The operation is convenient and fast, which improves the practicality of the device.

[0042] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes, additions, subtractions, or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
