Description

Technical Field

[0001] The utility model relates to the technical field of warning signs, in particular to an on-site warning sign. Background Art

[0002] Construction refers to production activities during the implementation phase of engineering construction. Warning signs are generally used outside the construction site to warn passers-by, thereby providing a certain degree of protection to prevent accidents and reduce losses.

[0003] Some existing warning signs are composed of a bracket and a sign, and the shape of the bracket is a triangular shape with better stability. Most warning signs are fixed and cannot be folded. During construction, workers often prepare more warning signs for safety reasons. These unused warning signs will be placed in a unified manner. Warning signs with fixed bracket shapes will occupy a large space due to their shape, which will cause a certain waste of space resources. In order to solve this technical problem, the utility model proposes an on-site warning sign. Utility Model Content

[0004] The main purpose of the utility model is to provide an on-site warning sign, which can effectively solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A field warning sign includes a warning sign body, wherein the interior of the warning sign body is slidably connected to a support column, the interior of the support column is slidably connected to a cross plate, a slide groove is provided inside the warning sign body, the inner side wall of the slide groove is slidably connected to a cross bar, the outer surface of the cross bar is rotatably connected to a telescopic plate 1, a limiting mechanism is provided on the outer surface of the warning sign body, the interior of the support column is slidably connected to an insertion rod, an adjustment hole is provided inside the insertion rod, one end of the insertion rod is connected to a gear, and the outer surface of the gear is meshed with a telescopic plate 2.

[0007] Preferably, the limiting mechanism comprises a limiting shell, the outer surface of the limiting shell is connected to the outer surface of the warning sign body, and the interior of the limiting shell is slidably connected to a plug plate.

[0008] Preferably, the outer surface of the plug plate is slidably connected to the outer surface of the warning sign body, the inner thread of the plug plate is connected to a threaded rod, and the outer surface of the threaded rod is rotatably connected to the inner part of the limit shell.

[0009] Preferably, the outer surface of the transverse plate is slidably connected to a sleeve, the interior of the sleeve is connected to a spring, and the outer surface of the sleeve is engaged with the interior of the warning sign body.

[0010] Preferably, one end of the spring away from the sleeve is connected to the outer surface of the transverse plate, and the outer surface of the telescopic plate is slidably connected to the inner side wall of the sliding groove.

[0011] Preferably, the outer surface of the gear is slidably connected to the interior of the support column, and the interior of the support column is connected to a rotating rod.

[0012] Preferably, the outer surface of the telescopic plate 2 is slidably connected to the inner portion of the support column, and the inner portion of the telescopic plate 2 is rotatably connected to the outer surface of the rotating rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the utility model, through the cooperation between the support column and the telescopic plate one, first the support column can be moved. After the telescopic plate two is put into the support column, the support column can be put into the warning sign by moving the position of the cross bar. The telescopic plate one can be moved. When the warning sign body is put away, the limiting mechanism can be pulled out from the inside of the telescopic plate two, and then the telescopic plate two can be moved so that the telescopic plate two can be moved into the warning sign body, thereby putting away the bracket of the warning sign body and reducing the space occupied by the warning sign body. It is very easy to use and solves the problem of wasting space resources due to the shape of the bracket of the warning sign.

[0015] In the present invention, the gear can be moved through the cooperation between the gear and the sleeve and other components. After the gear is separated from the telescopic plate 2, the user can rotate the telescopic plate 2 to adjust the angle between the telescopic plate 2 and the support column. Then, the gear can be inserted into the telescopic plate 2 to limit the position of the telescopic plate 2, thereby providing an inclined support force to the warning sign body, making it difficult for the warning sign body to tilt forward. The sleeve can limit the position of the support column in the warning sign body. By moving the sleeve, the horizontal plate can be inserted into a position relatively high above the support column, so that the warning sign body will not slide downward under the support of the sleeve, thereby completing the support of the warning sign, which is very convenient.

[0025] A slide groove 4 is provided inside the warning sign body 1, and a cross bar 5 is slidably connected to the inner wall of the slide groove 4. The inner wall of the slide groove 4 is relatively smooth, and other objects are subject to less friction when moving on the inner wall of the slide groove 4. The slide groove 4 will limit the position to which the cross bar 5 can move.

[0026] The outer surface of the cross bar 5 is rotatably connected to a telescopic plate 6, the outer surface of the warning sign body 1 is provided with a limiting mechanism 7, the inner sliding connection of the support column 2 is connected to an insertion rod 8, the cross bar 5 can provide support for the telescopic plate 6, allowing the telescopic plate 6 to rotate around the cross bar 5, the support column 2 will limit the direction in which the insertion rod 8 can move, the extension plate inside the telescopic plate 6 can be pulled out, and the length of the pull-out can be controlled.

[0027] An adjustment hole 9 is provided inside the insertion rod 8, and a gear 10 is connected to one end of the insertion rod 8. The outer surface of the gear 10 is engaged with a telescopic plate 2 11. The user can pull the insertion rod 8 to move by extending his fingers into the adjustment hole 9. The insertion rod 8 will fix the position of the gear 10, and will move with the gear 10 when the insertion rod 8 moves. When the gear 10 is engaged with the telescopic plate 2 11, the telescopic plate 2 11 cannot rotate, and the extension plate inside the telescopic plate 2 11 can be pulled out, and the length of the pull-out can be controlled.

[0028] The limiting mechanism 7 includes a limiting shell 701, the outer surface of the limiting shell 701 is connected to the outer surface of the warning sign body 1, and the internal sliding connection of the limiting shell 701 is a plug plate 702. The warning sign body 1 will fix the position of the limiting shell 701, so that the limiting shell 701 cannot move. The limiting shell 701 will limit the direction in which the plug plate 702 can move, so that the position of the plug plate 702 will not deviate.

[0029] The outer surface of the plug plate 702 is slidably connected to the outer surface of the warning sign body 1, and the internal thread of the plug plate 702 is connected to the threaded rod 703. The outer surface of the threaded rod 703 is rotatably connected to the inner part of the limit shell 701. The warning sign body 1 will limit the direction in which the plug plate 702 can move. A hole is opened inside the telescopic plate 6. After the telescopic plate 6 is rotated to a suitable position, the plug plate 702 can be inserted into the hole opened inside the telescopic plate 6 to limit the position of the plug plate 702. When the threaded rod 703 rotates, the movement of the plug plate 702 can be controlled. The limit shell 701 will limit the position in which the threaded rod 703 can move, so that the threaded rod 703 can only rotate and cannot move up and down.

[0030] The outer surface of the horizontal plate 3 is slidably connected with a sleeve 12, and the inside of the sleeve 12 is connected with a spring 13. The outer surface of the sleeve 12 is clamped with the inside of the warning sign body 1. The sleeve 12 allows the two horizontal plates 3 to be at the same height. The sleeve 12 will limit the position of the spring 13, and the sleeve 12 can be clamped inside the warning sign body 1.

[0031] The end of the spring 13 away from the sleeve 12 is connected to the outer surface of the horizontal plate 3, and the outer surface of the telescopic plate 6 is slidably connected to the inner wall of the slide groove 4. The spring 13 can provide thrust for the horizontal plate 3, so that the horizontal plate 3 can move out of the sleeve 12 when it is not blocked by other objects. When the telescopic plate 6 has not moved to a position close to the bottom of the warning sign body 1, the telescopic plate 6 can only rotate around the cross bar 5.

[0032] The outer surface of the gear 10 is slidably connected to the inside of the support column 2. The support column 2 is internally connected to a rotating rod 14. The support column 2 will limit the direction in which the gear 10 can move. The support column 2 will fix the position of the rotating rod 14 so that the rotating rod 14 cannot move.

[0033] The outer surface of the telescopic plate 2 11 is slidably connected to the inside of the support column 2, and the inside of the telescopic plate 2 11 is rotatably connected to the outer surface of the rotating rod 14. The support column 2 is used to limit the direction in which the telescopic plate 2 11 can move. The rotating rod 14 can provide support for the telescopic plate 2 11, allowing the telescopic plate 2 11 to rotate around the rotating rod 14.

[0034] Working principle: When using this device, you first need to pull out the support column 2 from the warning sign body 1, then put your finger into the adjustment hole 9 to pull the insertion rod 8 to pull the gear 10 out of the telescopic plate 2 11, rotate the telescopic plate 2 11 to a suitable angle, and extend its extension rod to a position in contact with the ground, then move the cross plate 3, let the sleeve 12 move the two cross plates 3 to the upper position of the support column 2, the spring 13 will push the cross plate 3 to insert it into the hole opened at the upper part of the support column 2, so that the sleeve 12 is stuck in the warning sign body 1, and then the user moves the telescopic plate 16 downward. After moving to the bottom, the user can rotate the telescopic plate 16. After the telescopic plate 16 is rotated to the appropriate position, the user can rotate the threaded rod 703 to insert the insertion plate 702 into the telescopic plate 16, so that the telescopic plate 16 cannot move, so that the warning sign body 1 can be placed on the ground. When it needs to be stored, you only need to retract these components into the warning sign body 1.
