Description

Technical Field

[0001] The utility model relates to the technical field of isolation warning, in particular to a warning device. Background Art

[0002] In public places where a large number of people gather, such as exhibitions, press conferences, and speeches, in order to protect personal safety and equipment and facilities, warning devices that serve as isolation are usually installed. The most common warning devices are various guardrails.

[0003] However, traditional guardrails take up too much space when stored. Even foldable telescopic guardrails with scissor frames still take up a lot of space when folded. Although these guardrails can serve as warnings, they are too bulky, especially when interception and protection of a larger length range is required. The overall weight will be greatly increased, making it very inconvenient to use. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a warning device for the above-mentioned technical deficiencies, which occupies a small volume when stored, has a large expansion range, is light overall, and is easy to arrange.

[0005] The technical solution adopted by the utility model is as follows: providing a warning device, comprising a mounting base and a support base on the left and right sides; a storage cavity is opened at the lower right side of the mounting base; a continuously bent folding guard plate is stored in the storage cavity; the left end of the folding guard plate is fixed inside the storage cavity, and the right end is fixed to the support base; the upper and lower ends of the folding guard plate are respectively fixed with extended air pipes along their directions; a reversing air pump is fixed on the mounting base; the extended air pipes are connected with the air ports of the reversing air pump through air guide pipes; a plurality of reinforcing rods are fixed on the folding guard plate; the reinforcing rods are respectively arranged at the bending positions on the folding guard plate; a limiting groove is opened at the lower left end of the mounting base and the lower right end of the support base; a locking and sliding switching mechanism is arranged in the limiting groove;

[0006] The locking and sliding switching mechanism includes an expansion plate inserted in a limited groove; a ground nail is fixed at the lower end of the expansion plate; the lower end of the ground nail extends beyond the lower end of the limited groove; a first support is fixed at the upper end of the expansion plate; a first rolling ball is rollingly connected to the upper end of the first support; the center of the expansion plate is connected and locked to the limited groove by a connecting bolt.

[0007] To further optimize this technical solution, when the folding guard plate is folded into the storage cavity, the support seat is correspondingly inserted into the storage cavity.

[0008] To further optimize this technical solution, the lower end of the reinforcement rod of a warning device extends beyond the lower end of the folding guard plate; the lower end of the reinforcement rod is threadedly sleeved with a second support; and the lower end of the second support is rollingly connected to a second rolling ball.

[0009] To further optimize the technical solution, vertical connecting pin holes are provided on the upper portion of the mounting seat and the upper portion of the support seat of a warning device.

[0010] The beneficial effects of the present invention are:

[0011] The connection support of the two ends of the folding guard plate by the mounting seat and the support seat can make the folding guard plate stably placed after being stretched; the setting of the storage cavity can fold the folding guard plate for storage, and protect the folding guard plate during storage or transportation; a plurality of reinforcement rods are fixed on the folding guard plate, and the reinforcement rods are respectively arranged at the bending positions on the folding guard plate. The setting of the reinforcement rods can support the unfolded folding guard plate, make the folding guard plate more solid as a whole, and improve the protective warning effect; the center of the expansion plate is connected and locked with the limited groove by a connecting bolt, which can facilitate the change of the installation direction of the expansion plate in the limited groove, and the device can be firmly positioned on the ground by inserting the ground nails, and the overall movement of the device can be facilitated by the first rolling ball.

DETAILED DESCRIPTION

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0016] like Figure 1-2 As shown, a warning device includes a mounting base 1 and a support base 2 on the left and right sides; a storage cavity 3 is opened at the lower right side of the mounting base 1; a continuously bent folding guard plate 4 is stored in the storage cavity 3; the left end of the folding guard plate 4 is fixed inside the storage cavity 3, and the right end is fixed to the support base 2; the upper and lower ends of the folding guard plate 4 are respectively fixed with extended air pipes 5 along their directions; a reversing air pump 6 is fixed on the mounting base 1; the extended air pipes 5 are connected with the air ports of the reversing air pump 6 through air guide pipes 7; a plurality of reinforcing rods 8 are fixed on the folding guard plate 4; the reinforcing rods 8 are respectively arranged at the bending positions on the folding guard plate 4; a limiting groove 9 is opened at the lower left end of the mounting base 1 and the lower right end of the support base 2; a locking and sliding switching mechanism is provided in the limiting groove 9;

[0017] The locking and sliding switching mechanism includes an expansion plate 10 inserted into the limited groove 9; a ground nail 11 is fixed to the lower end of the expansion plate 10; the lower end of the ground nail 11 extends beyond the lower end of the limited groove 9; a first support 12 is fixed to the upper end of the expansion plate 10; a first rolling ball 13 is rollingly connected to the upper end of the first support 12; the center of the expansion plate 10 is connected and locked to the limited groove 9 by a connecting bolt 14.

[0018] When the device is stored or transported, the folding guard plate 4 is completely folded and stored inside the storage cavity 3. On the one hand, it reduces the floor space and improves the convenience of moving and storing. On the other hand, it provides shielding and protection for the folding guard plate 4, avoiding problems such as dust accumulation and deformation caused by external force collision.

[0019] Compared with the traditional folding method of the scissors frame, the folding guard plate 4 in this technical solution adopts a continuous bending structure, and the folding guard plate 4 can be made of thinner materials such as PVC plates and light steel plates. Under the premise of the same interception length, the space occupied after folding and the weight are smaller, which improves the convenience of staff in carrying, arranging and other work.

[0020] If you are worried that the folding guard plate 4 itself is not strong enough, you can install reinforcement rods 8 at the bends of the folding guard plate 4 as needed to improve the overall strength of the folding guard plate 4. Of course, the installation of reinforcement rods 8 will inevitably increase the space occupied by the folding guard plate 4 after folding, so the number of reinforcement rods 8 can be arranged in the areas that need specific reinforcement, and it is not necessary to install them at every bend.

[0021] In addition, in addition to being able to be extended and retracted as a whole through direct manual operation, in order to improve efficiency, in the present technical solution, the reversing air pump 6 (which can control and change the direction of gas flow from the air port) can be started. When air is blown through the air port of the reversing air pump 6, the gas enters the extension air pipe 5, and the extension air pipe 5 can gradually straighten, thereby driving the overall extension of the folding guard plate 4. When air is pumped through the air port of the reversing air pump 6, the gas inside the extension air pipe 5 is pumped out, and the extension air pipe 5 gradually contracts, which can drive the folding guard plate 4 to return to the folded state. Since the pumping and blowing process of the air pump is very rapid, the extension or contraction operation of the folding guard plate 4 can be achieved more quickly through this operation, especially when the warning range of the present device is relatively long, saving time.

[0022] When the foldable guard plate 4 is folded into the storage cavity 3, the support base 2 is correspondingly inserted into the storage cavity 3, further increasing the convenience of storage.

[0023] like Figure 2As shown, the lower end of the reinforcement rod 8 extends beyond the lower end of the folding guard plate 4; the lower end of the reinforcement rod 8 is threadedly connected to a second support 15; the lower end of the second support 15 is rollingly connected to a second ball 16, which can be rotated by the second ball 16 when the folding guard plate 4 (especially when the warning length is large) is folded or extended, making its movement operation smoother and the support better.

[0024] like Figure 1 As shown, vertical connecting pin holes 17 are provided on the upper part of the mounting base 1 and the upper part of the support base 2, which facilitates connecting multiple devices in series using external connecting pins. For example, it is more convenient to add multiple devices to be used in conjunction to define a warning range, or to install partition doors for specific personnel to enter and exit.
