Description

Technical Field

[0001] The present invention relates to the technical field of signboards, and in particular to a warning signboard. Background Art

[0002] When the relevant equipment of the power plant needs to be repaired or inspected, in order to ensure safe operation, it is necessary to hang signs such as "Do not close the switch, there are people working on the line". Its main purpose is to warn all personnel that the equipment has been shut down and there are people working on the line. It is prohibited to resume power supply to avoid personal electric shock accidents to workers on the line due to premature power supply.

[0003] Existing signage comes in two types: rope-suspended and soft-magnetic. Hanging signage features two holes in the sign, tied with a rope. These signs are only suitable for hanging locations and require a suitable hanging object, such as the "Portable Electric Signage" disclosed in Patent No. CN215007261U. Magnetic signage is also only suitable for locations suitable for magnetism and requires a suitable magnetic metal object, such as the "Magnetic Signage" disclosed in Patent No. CN222088222U. Signage with both a rope and magnets can also be used. However, in locations unsuitable for hanging but suitable for magnetism, the rope often compromises the magnetization or warning effect, such as the "Magnetic Electrical Signage" disclosed in Patent No. CN201716932U. Furthermore, in locations without either a hanging object or a magnetic object (such as the ground), simply placing the sign horizontally on the ground offers poor warning effectiveness, or finding temporary supports can be haphazard, unstable, and prone to collapse.

[0004] Therefore, the present invention requires a warning sign that integrates hanging, magnetic attraction and support, is suitable for all places, and can hide the rope for easy storage. Summary of the Invention

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] Example 1: A warning sign, such as Figure 1-Figure 5 Shown, including: The sign body 100 is a square symmetrical structure, with a first groove 101 vertically opened inside. The first groove 101 is one on each side. The first groove 101 is a cylindrical groove that is wide in the middle and narrow at both ends. Two round balls 103 are symmetrically arranged at the ends of the first groove 101. A first return spring 102 is arranged in the middle of the first groove 101. Hanging ropes 104 (such as Figures 1-4 As shown by the red lines in the figure, the hanging rope 104 passes through the middle of the two round balls 103 and is hidden in the second grooves 108 on the upper and lower walls of the sign body 100. The second groove 108 is a rectangular groove with a semicircular notch 106 in the middle to facilitate pulling out the hanging rope 104.

[0023] A third groove 105 is symmetrically formed in the upper and lower parts of the sign body 100 . The third groove 105 is a horizontally arranged long strip structure. A first magnet (not shown in the drawings) matching the size of the first magnet is embedded in the third groove 105 .

[0024] There is also a fourth groove 107 in the middle of the outer wall of the sign body 100. The fourth groove 107 is a circular structure. A third magnet (not shown in the drawings) that matches the size of the fourth groove 107 is embedded in the position corresponding to the fourth groove 107 inside the sign body 100.

[0025] On the front side of the outer wall of the sign body 100 are printed words and patterns (not shown) such as “Do not close the switch, someone is working”.

[0026] like Figure 5 As shown, the accessory body 200 is a trapezoidal bending structure that is narrow at the top and wide at the bottom, and the upper part is a circular structure. A protruding second attractive magnet 201 is arranged on the upper side of the circular structure, and the size of the second attractive magnet 201 matches the fourth groove 107.

[0027] One-way suspension usage: Figure 3 As shown, by pulling the hanging rope 104 through the notch 106, the rope 104 overcomes the elastic force of the first return spring 102 and is pulled out due to the free rotation of the circular ball 103 (reducing friction), and the hanging rope 104 is hung on a fixed object with the front side facing outward. Because the first groove 101 is a cylindrical groove with a wide center and narrow ends, the diameter of the first return spring 102 is larger than the diameter of the narrow cylinders at the ends of the first groove 101. The stretched length of the spring is limited, preventing the spring from being overstretched and causing elastic failure.

[0028] Two-way suspension usage: Figure 4As shown, pull out the symmetrical hanging rope 104 and hang it on a fixed object. The upper and lower two-way fixation makes the suspension more stable, especially suitable for outdoor work, and can effectively prevent the warning sign from being blown over by wind.

[0029] Remove the hanging rope 104 from the fixed object and loosen it. Under the tension of the first return spring 102, the hanging rope 104 is pulled into the first groove 101 and the second groove 108 and is hidden. Figure 1 shown.

[0030] Magnetic usage: In a suitable place, such as the magnetic metal door of a cabinet, the hanging rope 104 is pulled into the first groove 101 and the second groove 108 and hidden, and the first magnet in the third groove 105 inside the sign body 100 can be sucked onto the metal door; since the hanging rope 104 has been hidden, for transparent glass doors encountered on site, the two sign bodies 100 can also be attracted to each other to achieve this, and will not be affected by the hanging rope 104.

[0031] For places with magnetic attraction, single (double) suspension and magnetic attraction work simultaneously, making the warning sign more stable and more resistant to wind.

[0032] Support usage: such as Figure 6 As shown, on the ground, the second attraction magnet 201 at the upper end of the accessory body 200 is placed in the fourth groove 107 on the back of the sign body 100, and the accessory body 200 is adsorbed and fixed on the side wall of the sign body 100 through the magnetic attraction cooperation of the second attraction magnet 201 and the third attraction magnet; and embedded therein, the accessory body 200 and the sign body 100 form an inverted V-shaped structure that can be placed on the ground. The second attraction magnet 201 is a circular magnetic structure that can be rotated at any angle in the fourth groove 107 for easy support. If the accessory body 200 is lost, it can also be replaced with local materials, such as on-site tools such as screwdrivers.

[0033] Example 2: includes all the contents of Example 1, except that: like Figure 8 As shown, the lanyard 104 is provided with one-way latching teeth 1041 at equal intervals along its length direction, and the one-way latching teeth 1041 can be made of rubber.

[0034] like Figure 7 、 Figure 9 、 Figure 10 As shown, a barrier member 300 is also included. The barrier member 300 is made of insulating material. The shape of the barrier member 300 is adapted to the notch 106 so that when the hanging rope 104 is hidden, the barrier member 300 is just embedded in the notch 106.

[0035] The barrier 300 is provided with two through-holes 301 for the hanging rope 104 to pass through. The hanging rope 104 is adapted to the through-holes 301. The barrier 300 is provided with a ratchet 302, a pusher 303, a connecting rod 304 and a second return spring 305. One end of the pawl 302 is rotatably connected to the interior of the barrier 300 , and the other end (free end) of the pawl 302 extends into the corresponding through-hole 301 for one-to-one engagement with the one-way latching tooth 1041 on the lanyard 104 ; The pusher 303 slides linearly inside the barrier 300 , and the two ends of the second return spring 305 are respectively connected to the pusher 303 and the inner wall of the barrier 300 ; the two ends of the connecting rod 304 are respectively hinged to the pawl 302 and the pusher 303 .

[0036] Under normal conditions, the pusher 303 moves upward and resets under the elastic force of the second reset spring 305 , and pushes the pawl 302 to rotate through the connecting rod 304 , so that the free end of the pawl 302 maintains a one-way engagement with the one-way tooth 1041 on the lanyard 104 .

[0037] It also includes a push rod 306, which slides linearly relative to the partition member 300 and will not fall off. One end of the push rod 306 extends to the partition member 300 and can abut against the pushing member 303, and the other end of the push rod 306 extends to the outside of the partition member 300 for operation; the push rod 306 is located inside the partition member 300 and is provided with a guide member 307 with an elastic structure. The guide member 307 with an elastic structure uses its own elastic force to place its free end in the guide groove 308 to prevent it from falling off.

[0038] The barrier member 300 is provided with a guide groove 308 inside. Figure 10 As shown, the guide groove 308 includes a plurality of slide grooves that are sequentially connected end to end to form a closed loop structure, and a step is provided between two adjacent slide grooves (such as Figure 9 ), the blue arrow indicates the unidirectional movement direction of the end of the guide member 307 in the guide groove 308.

[0039] Under normal circumstances, the end of the guide member 307 is relatively located in the initial position, and the two adjacent slide grooves in the middle prompt position are provided with a push-type switch. The barrier member 300 has an alarm built in. Pressing the switch once triggers the alarm once, and the alarm can make a sound to remind.

[0040] Working principle: When the circuit breaker is opened, the hanging rope 104 can be hung on the closing switch of the circuit breaker, and then the barrier 300 can be pushed to move unidirectionally relative to the hanging rope 104 and close to the closing switch of the circuit breaker. The hanging rope 104 and the barrier 300 are fixed on the closing switch of the circuit breaker. The barrier 300 with a certain size is used to prevent the closing switch of the circuit breaker from closing.

[0041] When the barrier member 300 needs to be removed from the closing switch of the circuit breaker, the push rod 306 is pressed, and the push rod 306 drives the guide member 307 to move accordingly. During this process, the movement of the end of the guide member 307 in the guide groove 308 is restricted; When the end of the guide member 307 moves from the initial position, it encounters the first turning point (relative to the middle prompt position) and triggers the first switch, and the alarm emits the first sound to remind; Then the push rod 306 moves back and forth a short distance, so that the end of the guide member 307 moves to the second turning point along the direction of the arrow, and triggers the second switch, and the alarm emits a second sound to remind; After that, the push rod 306 moves back and forth a short distance again, so that the end of the guide member 307 moves to the third turn in the direction of the arrow (relative to the trigger position). At this time, the push rod 306 relatively pushes the abutting push member 303 downward to the lower limit position, and then drives the pawl 302 to rotate and move through the connecting rod 304, so that the free end of the pawl 302 is separated from the one-way tooth 1041 of the hanging rope 104, and then the barrier member 300 can be driven to move in the opposite direction relative to the hanging rope 104, so that the hanging rope 104 can be detached from the closing switch of the circuit breaker. Without the influence of the barrier member 300, the switch of the circuit breaker can be closed normally.

[0042] Then, the push rod 306 is driven to move upward, so that the end of the guide member 307 moves to the initial position.

[0043] The cooperation between the end of the guide member 307 and the guide groove 308 realizes multiple forced reminders during the unlocking process.

[0044] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
