Description

Technical Field

[0001] The utility model relates to the technical field of natural gas extraction and transportation, in particular to a fire extinguisher protection box. Background Art

[0002] Fire extinguishers are an important firefighting equipment in production and life, especially in flammable and explosive high-risk industries such as petroleum and petrochemical industries. When storing existing fire extinguishers, they are generally placed directly in an open protective box or a closed protective box with a retractable lid.

[0003] However, in the field of natural gas extraction and transportation technology, fire extinguishers are often placed directly outdoors. When the temperature is high in the summer, the fire extinguishers are prone to overpressure; when the temperature is low in the winter, especially at night, the fire extinguishers are prone to underpressure; and when working in the gas field, it is often necessary to carry a fire extinguisher with you. If the fire extinguisher is simply placed directly in the protective box, the fire extinguisher is prone to jumping in the protective box while the vehicle is driving, causing the fire extinguisher to bump into or even fall over inside the protective box, which in turn causes the cylinder of the fire extinguisher to deform and be damaged. Utility Model Content

[0004] The purpose of the utility model is to provide a fire extinguisher protection box to overcome the shortcomings of the prior art in which the fire extinguisher is directly placed in the box, which is prone to overpressure or underpressure due to changes in temperature, and is prone to knocking against the box when carried in a vehicle, thereby causing damage.

[0005] In a first aspect, the present invention provides a fire extinguisher protection box, comprising a box body for accommodating a fire extinguisher, the box body including an openable and closable box cover, and further comprising:

[0006] A heat-insulating layer connected to the inner side of the box;

[0007] A clamping structure comprising at least two clamping parts, the clamping parts being able to move closer to each other to clamp the fire extinguisher and being able to move away from each other to release the fire extinguisher;

[0008] The boss structure is connected to the box cover. When the box cover is closed, the boss structure can abut against at least one clamping portion, so that the clamping portions are close to each other.

[0009] The opening and closing methods of the box cover include but are not limited to rotating, sliding, and detachable.

[0010] Specific forms of the thermal insulation layer include but are not limited to thermal insulation cotton, thermal insulation foam, rock wool board, etc.

[0011] The ability of two adjacent clamping parts to move closer to or farther away from each other can be achieved through various mechanisms, including but not limited to making the two adjacent clamping parts movably connected to each other, and making the clamping parts movably connected to the box body; the specific forms of the movable connection include but are not limited to swing connection and sliding connection, and the corresponding specific mechanisms include but are not limited to hinges, linear bearings or rolling bearings, slide rails, and pulleys.

[0012] When the box lid is closed, the boss structure can abut against at least one clamping part. For example, if four clamping parts are provided in the box body, the boss structure can either abut against all four clamping parts, thereby driving all four clamping parts to move, or abut against only a part of the clamping parts, thereby reducing the size of the boss structure.

[0013] On the one hand, the fire extinguisher protection box of this solution is provided with an insulation layer on the inner side of the box body, which can reduce the impact of the ambient temperature on the fire extinguisher, thereby reducing the probability of the fire extinguisher failing due to overpressure or underpressure; at the same time, this solution is also provided with a clamping structure for clamping the fire extinguisher, which can maintain the relative position of the fire extinguisher and the box body unchanged, thereby preventing the fire extinguisher from hitting the box body or tipping over in the box body, thereby avoiding damage to the fire extinguisher.

[0014] In order to avoid the clamping structure from hindering the use of the fire extinguisher, this solution further configures the clamping structure to be driven by the boss structure on the box cover, that is, when the box cover is closed, the boss structure will compress the clamping structure to automatically clamp, thereby preventing the fire extinguisher from hitting the box body or tipping over in the box body; when the box cover is opened, the clamping structure loses the pressure of the boss structure and cannot clamp, and the operator can take the fire extinguisher out of the box body relatively effortlessly.

[0015] Preferably, one end of the boss structure for abutting against the clamping portion and a portion of the clamping portion for abutting against the boss structure are both chamfered.

[0016] Specific forms of chamfers include but are not limited to square corners and rounded corners.

[0017] This solution can guide the contact between the boss structure and the clamping part through chamfering, so that the driving action of the boss structure on the clamping part is smoother, and the probability of the boss structure and the clamping part getting stuck is reduced.

[0018] Preferably, the number of the clamping structures is greater than one, and the clamping structures are distributed at intervals along the height direction of the box body.

[0019] This solution recommends setting up multiple clamping structures along the height direction of the box, which can enhance the support effect on the fire extinguisher and further prevent the fire extinguisher from colliding with the box or tipping over inside the box.

[0020] Preferably, an elastic element is provided between two adjacent clamping parts, and / or an elastic element is provided between the clamping part and the box body.

[0021] The specific forms of the elastic element include but are not limited to rubber blocks, coil springs, and disc springs; the setting methods of the spring include but are not limited to being set between two adjacent clamping parts, and being set between the clamping part and the box body; the elastic force or pulling direction of the spring is determined according to actual needs. For example, for a clamping part that can abut against the boss structure and clamp, the spring can be set to make the two adjacent clamping parts move away from each other, so that the clamping part can automatically release the fire extinguisher after the box lid is opened; for a clamping part that cannot abut against the boss structure and clamp, the spring can be set to make the two adjacent clamping parts move closer to each other, so that the fire extinguisher can be automatically clamped without the drive of the boss structure.

[0022] This solution recommends adding an elastic element to the clamping portion to enable the clamping portion to automatically loosen or clamp the fire extinguisher.

[0023] Preferably, the box body includes an inner shell body, a distance is provided between the inner shell body and an inner side surface of the box body, and a heat insulation layer is provided between the inner shell body and the box body.

[0024] This solution forms a sandwich structure among the box body, the heat insulation layer and the inner shell, which can not only further improve the heat insulation effect of this solution, but also improve the rigidity of this solution, thereby enabling this solution to more reliably protect the fire extinguisher.

[0025] Preferably, the outer surface of the box is provided with a reflective heat-insulating coating.

[0026] Reflective heat-insulating coatings include but are not limited to aluminum foil coatings, ceramic coatings, and fluorocarbon coatings.

[0027] This solution enables the box to reflect sunlight, thereby further preventing the temperature inside the box from being too high.

[0028] Preferably, at least two handles are connected to the box body, and the handles are distributed on at least two opposite sides of the box body.

[0029] This solution can facilitate operators to carry the box.

[0030] Preferably, a locking structure is provided between the box body and the box cover, and the locking structure can lock the opening and closing of the box cover.

[0031] Specific forms of the locking structure include but are not limited to a latch type, a lock type, and a threaded connector type.

[0032] This solution adds a locking structure to the box lid, which can prevent the box lid from opening accidentally. And because the clamping of at least one clamping part in this solution depends on the closed box lid, this solution can also prevent the box lid from opening accidentally, causing the corresponding clamping structure to fail, thereby ensuring the clamping reliability of the clamping structure.

[0033] Preferably, the locking structure includes a first limiting hole, a second limiting hole and a latch, the first limiting hole is set on the box lid, and the second limiting hole is set on the box body; when the box lid is closed, the first limiting hole can be aligned with the second limiting hole, and inserting the latch into the aligned first limiting hole and second limiting hole can lock the opening and closing of the box lid.

[0034] This solution recommends one of the specific locking structures.

[0035] Preferably, at least three supporting feet are provided at the bottom of the box body, and the supporting feet are used to contact the ground.

[0036] This solution can prevent the box from directly contacting the ground, thereby reducing heat transfer between the box and the ground and optimizing the heat dissipation at the bottom of the box.

[0037] Compared with the existing technology, the beneficial effects of the present invention are:

[0038] The utility model provides a fire extinguisher protection box. By arranging a heat insulation layer on the inner side of the box body, the influence of the ambient temperature on the fire extinguisher can be reduced, thereby reducing the probability of the fire extinguisher failing due to overpressure or underpressure; at the same time, the present solution also provides a clamping structure for clamping the fire extinguisher, which can maintain the relative position of the fire extinguisher and the box body unchanged, thereby preventing the fire extinguisher from colliding with the box body or tipping over in the box body, thereby avoiding damage to the fire extinguisher.

[0039] In order to avoid the clamping structure from hindering the use of the fire extinguisher, this solution further configures the clamping structure to be driven by the boss structure on the box cover, that is, when the box cover is closed, the boss structure will compress the clamping structure to automatically clamp, thereby preventing the fire extinguisher from hitting the box body or tipping over in the box body; when the box cover is opened, the clamping structure loses the pressure of the boss structure and cannot clamp, and the operator can take the fire extinguisher out of the box body relatively effortlessly.
