Description

Technical Field

[0001] The utility model relates to the technical field of construction fences, in particular to a fence with a warning function. Background Art

[0002] In the process of power construction and maintenance, in order to prevent the surrounding people from being affected by the construction, it is necessary to set up power construction fences around the power construction site, and use the fences to enclose the power construction site, so as to ensure the safety during the power construction process. Therefore, in order to improve the practicality of the power construction fence, we propose a fence with a warning function, among which the "a fence with a warning function" disclosed by the application number "CN210636914U" has solved the problem that it takes a lot of time to move the fence to a special cleaning place for cleaning, which greatly reduces the work efficiency of the workers. However, in actual use, power construction fences with similar structures still have many defects, such as: stretching through cross-installed connecting rods, so the enclosure range of the device is limited by the number and length of the connecting plates, and the connecting rods made of hard materials will wear during use, and the device occupies a large space during transportation, thereby reducing the practicality and portability of the device; the traditional fence will cause the pile barrels fixed at both ends to be subjected to horizontal tension due to the traction of the fence, so that the pile barrels are prone to tipping over during use, and the pile barrels are in a tilted state for a long time, which will affect the stability of the bottom of the device, thereby reducing the durability of the device, so a fence with a warning function is needed. Utility Model Content

[0003] The purpose of the utility model is to provide a fence with a warning function to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fence with a warning function, comprising a retracting mechanism, a vertical pole, a chassis and a plastic film, a connecting plate is installed on one side of the plastic film, three groups of hooks are installed on one side of the connecting plate, a fixed rod is installed on one side of the hook, two groups of locks are installed on one side of the vertical pole, a chassis is installed on the bottom of the vertical pole, a retracting mechanism is installed inside the vertical pole, a retracting rod is installed inside the retracting mechanism, clamping disks are installed at both ends of the retracting rod, a central axis is installed on one side of the clamping disk, and a plastic film extending from the vertical pole is installed around the outer side of the retracting rod.

[0005] When using a fence with a warning function in the technical solution, the plastic film is pulled out from the outside of the reeling rod by pulling the connecting plate, and the locking grooves on both sides of the plastic film are locked and fixed using the locking buckle, so that the hook is locked and connected with the hanging ring on one side of the fixed rod, so that the plastic film encloses the connection between the fixed rod and the vertical rod, thereby improving the durability and portability of the device.

[0006] Preferably, a bearing seat is installed at one end of the central shaft, and a reset spring piece is installed around the outer side of the central shaft. The bearing seat can be axially connected to the central shaft, so that the central shaft can rotate. One end of the reset spring piece is fixedly connected to the bearing seat, and the other end is fixedly connected to the outer side of the central shaft, so that when the central shaft rotates, a torsional force can be applied to the central shaft, so as to drive the central shaft to rotate and reset the plastic film.

[0007] Preferably, an insulating seat is installed on the top of the vertical pole, and a gravel filling box A is installed at the bottom of the vertical pole. The insulating seat can insulate the top of the vertical pole to prevent the top of the vertical pole from being shocked, and the gravel filling box A can increase the weight of the lower half of the device, thereby lowering the center of gravity of the device as a whole to improve the stability of the device.

[0008] Preferably, a protective pad is installed at the bottom of the chassis, and fastening screws are installed on both sides of the chassis. The protective pad can increase the friction of the bottom of the chassis, thereby improving the stability of the bottom of the device, and the fastening screws can fix the chassis and the protective pad to increase the connection stability between the chassis and the protective pad.

[0009] Preferably, three sets of hanging rings are installed on one side of the fixed rod, and a gravel filling box B is installed at the bottom of the fixed rod. The hanging ring can cooperate with the hook to connect one side of the plastic film, so that the plastic film can be connected to the standing rod and the fixed rod, and the gravel filling box B can counterweight the fixed rod, thereby reducing the center of gravity height of the fixed rod and improving the stability of the fixed rod.

[0010] Preferably, the two sides of the plastic film are provided with snap-fit ​​grooves at equal intervals, and the two sides of the plastic film are provided with record plates at equal intervals. The snap-fit ​​grooves can make the lock buckle engage with the plastic film, thereby making the plastic film extending out of the vertical rod part free from stress, thereby preventing the plastic film from being pulled by the torsion of the retracting mechanism and causing the fixed rod to deviate, thereby ensuring the stability of the vertical rod and the fixed rod when in use.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model installs a plastic film on the outside of the retracting rod, so that the range of the device enclosure can be flexibly adjusted through the plastic film. The plastic film can reduce the loss of internal components of the device during use and reduce the weight of the device. The vertical pole and the fixed pole can also be carried separately, which increases the practicality and portability of the device.

[0013] 2. The utility model installs a lock buckle on one side of the vertical pole, and can limit and fix the plastic film through the cooperation of the lock buckle and the card slot, so that the plastic film between the vertical pole and the fixed point rod is in a stress-free state and is only used for the connection between the vertical pole and the fixed point rod. Therefore, the vertical pole and the fixed point rod can be balanced in the horizontal direction when in use, thereby ensuring the stability of the device. BRIEF DESCRIPTION OF THE DRAWINGS
