Description

Technical Field

[0001] This utility model relates to the field of fire box technology, specifically a fixing structure for a fire box. Background Technology

[0002] Fire extinguisher boxes are one of the most commonly used fire-fighting equipment. They can be used to store fire extinguishers, fire hoses, and other fire-fighting equipment, and are widely used in stairwells, corridors, and other places to prevent and extinguish fires.

[0003] Currently, there are three main methods for installing and fixing fire extinguisher boxes: surface mounting, concealed mounting, and semi-concealed mounting. Surface mounting involves fixing the fire extinguisher box to the outside of the wall without needing to drill a mounting groove in the wall, which is relatively convenient for installation. However, it requires fixing the fire extinguisher box with bolts, brackets, etc., which is cumbersome and inconvenient for disassembling the fire extinguisher box. Therefore, this application proposes a fixing structure for fire extinguisher boxes to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fixing structure for fire boxes, which has the advantages of facilitating the installation and disassembly of fire boxes and solving the problems of the cumbersome and inconvenient process of fixing fire boxes with multiple bolts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing structure for a fire box, comprising a mounting plate and a mounting box located at the front and center of the mounting plate, wherein a support plate for placing the fire box is horizontally arranged on the front and near the bottom of the mounting box, and two connecting frames are horizontally arranged on both the left and right sides of the mounting plate, wherein a limiting frame slides on the front side of the connecting frames on both sides, and a fixing mechanism for horizontal sliding of the limiting frame is provided inside the mounting plate, and a limiting mechanism for limiting the fire box is provided on the front side of the mounting plate.

[0006] Furthermore, the fixing mechanism includes a motor mounted on the right side of the mounting box and located at its center. A protrusion is welded to the outside of the motor output shaft. Two movable blocks slide vertically on the upper and lower sides of the protrusion, respectively. A first spring is welded to the opposite side of each of the two movable blocks. A damper is welded to the opposite side of each of the two movable blocks. A hinge rod is hinged to the back side of each of the two movable blocks through a hinge shaft. Moving blocks slide horizontally inside the connecting frames on both the left and right sides.

[0007] Furthermore, the protrusion is elliptical in shape, and the hinge rods on the left and right sides are respectively hinged to the back of the moving blocks on the left and right sides via hinge shafts.

[0008] Furthermore, the two first springs are respectively fitted onto the outside of the two dampers, and the two first springs and dampers are respectively welded to the top and bottom walls of the mounting box cavity.

[0009] Furthermore, each of the four connecting frames has a sliding groove on its front and rear sides for the moving blocks to slide horizontally, and the four limiting frames are respectively welded to the front side of the four moving blocks.

[0010] Furthermore, the limiting mechanism includes two fixing grooves opened on the front side of the base plate, and a second spring is welded to the opposite side wall of the inner cavity of the two fixing grooves. A connecting block is welded to the opposite side of the two second springs, and a trapezoidal block is welded to the front side of the two connecting blocks.

[0011] Furthermore, the hypotenuses of both trapezoidal blocks face away from the mounting plate and are located on the left and right sides of the mounting box.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The fixed structure of the fire box starts when the motor is started. The first springs on the upper and lower sides push the two movable blocks to move relative to each other, which in turn causes the upper and lower hinge rods to drive the upper and lower movable blocks to move horizontally towards each other. This causes the four limit brackets to start limiting the ends of the fire box, and the trapezoidal blocks on the left and right sides can also limit the left and right sides of the fire box, improving the stability of the fire box without affecting the purpose of opening the front door of the fire box.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 2 The fixing structure of a fire box in this embodiment includes a mounting plate 1 and a mounting box 3 located at the front and center of the mounting plate 1. A tray 5 for placing the fire box is horizontally arranged on the front and near the bottom of the mounting box 3. Two connecting frames 6 are horizontally arranged on the left and right sides of the mounting plate 1. A limit frame 7 slides on the front of the connecting frames 6 on both sides. The mounting plate 1 is provided with a fixing mechanism 2 for the limit frame 7 to slide horizontally. A limit mechanism 4 for limiting the fire box is provided on the front of the mounting plate 1.

[0021] Please see Figure 3 In this embodiment, the fixing mechanism 2 includes a motor 201 installed on the right side of the mounting box 3 and located at its center. A protrusion 202 is welded to the outside of the output shaft of the motor 201. Two movable blocks 203 slide vertically on the upper and lower sides of the protrusion 202 respectively. A first spring 204 is welded to the opposite side of the two movable blocks 203. A damper 205 is welded to the opposite side of the two movable blocks 203. A hinge rod 206 is hinged to the back side of the two movable blocks 203 through a hinge shaft. A moving block 207 slides horizontally inside the connecting frame 6 on both the left and right sides.

[0022] The protrusion 202 is an elliptical cylinder. The left and right hinge rods 206 are respectively hinged to the back of the left and right moving blocks 207 via hinge shafts. The two first springs 204 are respectively fitted on the outside of the two dampers 205. The two first springs 204 and the dampers 205 are respectively welded to the top and bottom walls of the inner cavity of the mounting box 3. The front and rear sides of the four connecting frames 6 are provided with moving grooves for the moving blocks 207 to slide horizontally. The four limiting frames 7 are respectively welded to the front of the four moving blocks 207.

[0023] Understandably, when motor 201 is started, protrusion 202 begins to rotate. Since the movable blocks 203 on both sides are no longer in contact with protrusion 202, the first springs 204 on the upper and lower sides begin to push the two movable blocks 203 to move relative to each other. This causes the hinge rods 206 on the upper and lower sides to drive the movable blocks 207 on the upper and lower sides to move horizontally towards each other, so that the four limit brackets 7 begin to limit the ends of the fire box.

[0024] Please see Figure 4In this embodiment, the limiting mechanism 4 includes two fixing grooves 401 opened on the front side of the base plate. A second spring 402 is welded to the opposite side wall of the inner cavity of the two fixing grooves 401. A connecting block 403 is welded to the opposite side of the two second springs 402. A trapezoidal block 404 is welded to the front side of the two connecting blocks 403.

[0025] The inclined sides of the two trapezoidal blocks 404 are both facing away from the mounting plate 1 and located on the left and right sides of the mounting box 3. The fire box to be fixed is pressed against the inclined sides of the two trapezoidal blocks 404 by its back side, so that the two trapezoidal blocks 404 move in opposite directions and the fire box is placed in contact with the upper surface of the support plate 5.

[0026] Understandably, the trapezoidal blocks 404 on both sides can also limit the left and right sides of the fire box, improving the stability of the fire box without affecting the purpose of opening the front door of the fire box.

[0027] All electrical components mentioned in this article are electrically connected to the main controller and power supply, and all electrical components mentioned are conventional and known devices. This application will not elaborate further. The main controller can be a conventional and known device such as a computer that performs control. The control circuit of the main controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so this utility model will not explain the control method and circuit connection in detail. At the same time, any parts of this utility model that are not described in detail are all common technologies known to those skilled in the art.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The working principle of the above embodiments is as follows:

[0030] When it is necessary to fix the fire box, the fire box to be fixed is pressed against the inclined sides of the trapezoidal blocks 404 on both sides of its back, so that the two trapezoidal blocks 404 move in opposite directions and the fire box is placed in contact with the upper surface of the support plate 5. Then the motor 201 is started, so that the protrusion 202 begins to rotate. Since the movable blocks 203 on both sides are no longer in contact with the protrusion 202, the first springs 204 on the upper and lower sides begin to push the two movable blocks 203 to move relative to each other. This causes the hinge rods 206 on the upper and lower sides to drive the movable blocks 207 on the upper and lower sides to move horizontally towards each other. This causes the four limit brackets 7 to start to limit the ends of the fire box. The trapezoidal blocks 404 on the left and right sides can also limit the left and right sides of the fire box, improving the stability of the fire box without affecting the purpose of opening the front door of the fire box.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
