Description

Technical Field

[0001] This utility model relates to the field of fire-fighting auxiliary equipment technology, specifically to a wall-mounted fire extinguisher bracket. Background Technology

[0002] Wall-mounted fire extinguisher brackets are widely used in various places such as shopping malls, schools, hospitals, industrial plants, and residential buildings. Their function is to securely fix fire extinguishers, ensuring that people can easily and quickly access fire extinguishers in emergency fire situations, thereby effectively extinguishing initial fires, reducing fire risks, and protecting people's lives and property.

[0003] According to the patented announcement (CN222266000U), a wall-mounted fire extinguisher bracket includes a connecting assembly. An adjusting box is fixedly connected to the front surface of the connecting assembly. Cavities are formed on both sides of the adjusting box, and a fixing assembly is slidably connected inside each cavity. In use, a fixing bolt passes through a through-slot to fix a fixing plate. A deformable flat steel hoop is used, and a limiting plate compresses a spring. A connecting rod slides outward to accommodate different sizes of fire extinguishers, and a limiting frame adapts to the expansion of the hoop. In this wall-mounted fire extinguisher bracket design, the fixing plate is mainly used to achieve a stable connection with the pre-set wall surface. Specifically, the fixing bolt passes through the through-slot to position the fixing plate at the desired location. However, in-depth analysis reveals significant drawbacks to this fixing method. When the fixing plate is positioned high, in the event of a fire, adults in a state of panic will find it difficult to quickly retrieve the fire extinguisher from the bracket. This will undoubtedly severely hinder the timeliness of firefighting operations, greatly reduce fire rescue efficiency, and lead to missed opportunities to extinguish initial fires. If the mounting plate is fixed in a low position, minors may not have sufficient awareness of the dangers of fire extinguishers and may treat them as toys to be played with carelessly. This can easily damage the fire extinguisher, preventing it from functioning properly when faced with a real fire, thus posing a huge threat to life and property safety. Utility Model Content

[0004] The purpose of this utility model is to provide a wall-mounted fire extinguisher bracket, which addresses the problem that the existing technology lacks a height adjustment mechanism for fire extinguishers. When the height is set too high, it is inconvenient for adults to access the extinguisher in emergencies, and when the height is set too low, it is easily damaged by minors, affecting the normal use of the fire extinguisher. This utility model proposes a solution that can effectively solve the problem of difficulty in accessing the fire extinguisher and the problem of children's misoperation caused by the unreasonable height of the fire extinguisher.

[0005] This utility model is achieved through the following technical solution:

[0006] A wall-mounted fire extinguisher bracket includes: a wall-mounted base plate with a lifting guide groove along its extension direction; a lifting locking control body installed on the lifting guide groove; a lifting unlocking body installed on the lifting guide groove, the height of which is greater than the height of the lifting locking control body; a lifting support plate slidably installed on the lifting guide groove, the lifting support plate having an avoidance groove along its extension direction, and first receiving grooves on opposite sides of the avoidance groove; a dual-state locking / unlocking assembly installed in the first receiving grooves; and a fire extinguisher bracket mounted on the lifting support plate. In the locked state, the lifting locking control body locks the dual-state locking / unlocking assembly, restricting the descent of the lifting support plate; in the unlocked state, the lifting unlocking body unlocks the dual-state locking / unlocking assembly, causing the lifting support plate to descend to its lowest point under gravity.

[0007] Furthermore, in this utility model, the above-mentioned dual-state locking and unlocking assembly includes an elastic element and a locking and unlocking element with an inclined surface structure; the locking and unlocking element is slidably installed in the first receiving groove, one end of the elastic element is connected to the locking and unlocking element, and the other end of the elastic element is connected to the bottom wall of the first receiving groove; wherein, when the locking and unlocking element moves upward, the inclined surface structure can act on the lifting lock control body, and then the locking and unlocking element can move a first distance into the first receiving groove.

[0008] Furthermore, in this utility model, the aforementioned dual-state locking / unlocking assembly includes a reset spring, a limiting member, a second receiving groove disposed on the lifting support plate, and a limiting groove disposed on the locking / unlocking member; the second receiving groove is connected to the first receiving groove; the limiting member passes through the reset spring; the reset spring is assembled in the second receiving groove, one end of the reset spring is connected to the outer wall of the limiting member, and the other end of the reset spring is connected to the inner wall of the second receiving groove, and the reset spring causes the limiting member to press against the locking / unlocking member; wherein, when the locking / unlocking member moves upward, the inclined structure can act on the lifting and unlocking body, and then the locking / unlocking member can move a second distance into the first receiving groove, the second distance being greater than the first distance, so that the limiting member can be inserted into the limiting groove and the locking / unlocking member is limited in the first receiving groove.

[0009] Furthermore, in this utility model, the above also includes a lifting knob; the lifting knob is assembled at the end of the limiting member, the lifting knob is located outside the second receiving groove, and the outer contour dimension of the lifting knob is larger than the inner contour dimension of the second receiving groove.

[0010] Furthermore, in this utility model, multiple power assist push buttons are installed on both sides of the aforementioned lifting platform.

[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0012] 1. The lifting lock control body is installed within the lifting guide groove. When the dual-state locking / unlocking component moves to the corresponding position, it effectively limits the dual-state locking / unlocking component. Through this limiting action, it successfully resists the downward movement tendency of the lifting tray due to gravity, allowing the lifting tray to remain stably in the set position. This function has significant safety protection value, effectively preventing minors from accidentally touching the fire extinguisher bracket, avoiding damage to the equipment due to improper operation, ensuring the safe storage of the equipment in non-emergency situations, and improving the safety of fire extinguisher storage in public places or home environments.

[0013] 2. The lifting unlocking body is installed within the lifting guide groove and located above the lifting lock control body, playing a crucial role in emergencies such as fires. When the dual-state locking and unlocking component moves to its corresponding position, it can quickly unlock the dual-state locking and unlocking component and cause it to fully retract into the first receiving groove for locking. This operation promptly releases the limit on the lifting tray, allowing it to quickly move downwards to the lowest point under gravity. This greatly improves the efficiency for adults to access fire extinguishers in emergencies, buying valuable time for timely fire suppression, enhancing fire emergency response capabilities, and helping to reduce fire-related losses.

[0014] 3. The dual-state locking and unlocking assembly is installed in the first receiving slot and has two working states. In the normal state, it works with the lifting lock control body to limit the lifting tray, maintaining the safe storage state of the equipment; in the emergency state, it works with the lifting unlocking body to release the limit state, enabling the lifting tray to descend rapidly. This flexible state switching design allows the equipment to be precisely controlled according to different usage scenarios and needs, ensuring both normal safety and meeting the requirements for rapid retrieval in emergencies, thus improving the practicality and applicability of the equipment. Its ingenious structural design utilizes elastic elements and locking and unlocking components with inclined surfaces to achieve automatic locking and unlocking functions through mechanical principles, eliminating the need for complex manual operation and improving the ease of use of the equipment.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0025] Example

[0026] Please refer to Figures 1 to 6 This application provides a wall-mounted fire extinguisher bracket 3. The wall-mounted base plate 1 serves as the basic load-bearing structure of the entire wall-mounted fire extinguisher bracket 3, and is reliably fixed to the wall, providing a stable installation platform for other components. A lifting guide groove 6 extends along the center of the wall-mounted base plate 1, serving as the track for the movement of the lifting support plate 2, determining its direction and range of movement. The lifting support plate 2 supports the fire extinguisher bracket 3, enabling vertical position adjustment. An avoidance groove 7 extends along the center of the base plate 1, cleverly preventing interference with the lifting unlocking body 5 and the lifting locking control body 4 when sliding within the lifting guide groove 6, ensuring smooth movement of the lifting support plate 2. First receiving grooves 9 are provided on opposite sides of the avoidance groove 7 for installing dual-state locking / unlocking components, providing space for their operation.

[0027] The lifting lock control body 4 is installed inside the lifting guide groove 6. When the dual-state locking and unlocking component moves to the corresponding position, it limits the dual-state locking and unlocking component. Through this limiting function, it can resist the downward movement tendency of the lifting tray 2 caused by gravity, so that the lifting tray 2 can be stably stopped in the set position, thereby achieving the purpose of preventing minors from touching the fire extinguisher bracket 3 and protecting the equipment.

[0028] The lifting unlocking mechanism is installed inside the lifting guide groove 6 and located above the lifting lock control body 4. In emergency situations such as fire, when the dual-state locking and unlocking component moves to the corresponding position, the dual-state locking and unlocking component is unlocked, causing it to fully retract into the first receiving groove 9 and lock, thus releasing the limit on the lifting pallet 2 and allowing the lifting pallet 2 to move downward under the action of gravity.

[0029] The dual-state locking and unlocking component is installed in the first receiving slot 9 and has two working states. In the normal state, it works with the lifting lock control body 4 to limit the lifting tray 2; in the emergency state, it works with the lifting unlocking body 5 to release the limit state. It is the core component for controlling the movement state transition of the lifting tray 2.

[0030] The fire extinguisher bracket 3 is used to place fire extinguishers directly. Through its connection with the lifting tray 2, it moves with the lifting tray 2 within the lifting guide 6, enabling the placement and retrieval of fire extinguishers at different heights.

[0031] Please refer to Figure 4 and Figure 5 In some embodiments of this application, the dual-state locking / unlocking assembly comprises an elastic element 15 (which may be a spring, elastic rubber, or elastic metal sheet, etc.) and a locking / unlocking element 10 with a beveled structure 11. One end of the elastic element 15 is securely connected to the locking / unlocking element 10, and the other end of the elastic element 15 is connected to the bottom wall of the first receiving groove 9. The locking / unlocking element 10 is slidably installed inside the first receiving groove 9.

[0032] Specifically, when the lifting plate 2 moves upward from its starting position, it drives the two unlocking components 10 on both sides to move upward synchronously due to its connection with the dual-state locking and unlocking assembly. During the process of the two unlocking components 10 moving to their corresponding positions with the lifting locking control body 4, the inclined structure 11 of the unlocking component 10 comes into contact with the lifting locking control body 4. Based on mechanical principles, the pressure exerted by the lifting locking control body 4 on the unlocking component 10 can be decomposed into a component force pointing inwards towards the first receiving groove 9 according to the law of force decomposition. Under the action of this component force, the unlocking component 10 is pushed into the first receiving groove 9 a certain distance, denoted as the first distance. At this point, the unlocking component 10 has not completely retracted into the first receiving groove 9.

[0033] Specifically, as the lifting plate 2 continues to move the unlocking component 10 upwards, when the unlocking component 10 passes the lifting locking control body 4 and reaches its upper position, the lifting locking control body 4 no longer applies pressure to the unlocking component 10. At this time, under the action of the elastic potential energy stored in the elastic member 15, the unlocking component 10 is ejected a corresponding distance away from the bottom wall of the first receiving groove 9, thus returning to its initial position. Since the unlocking component 10 has a straight surface structure below, after returning to its original position, this straight surface structure will interact with the lifting locking control body 4, forming a blocking effect and restricting the downward movement of the lifting locking control body 4. Furthermore, due to the motion correlation characteristics between the lifting locking control body 4 and the lifting plate 2, the position of the lifting plate 2 is effectively restricted, allowing the lifting plate 2 to remain stably in its current position, thus completing the locking function of the lifting plate 2.

[0034] Please refer to Figures 4 to 6 In some embodiments of this application, the dual-state locking / unlocking assembly mainly consists of a return spring 13, a limiting member 17, a second receiving groove 12 disposed on the lifting tray 2, and a limiting groove 16 disposed on the locking / unlocking member 10. In an emergency fire, the lifting tray 2 is limited to the lifting lock control body 4. At this time, the operator needs to continue pushing the lifting tray 2 upward. When the locking / unlocking members 10 on both sides of the lifting tray 2 move upward to the position corresponding to the lifting unlocking body 5, the inclined structure 11 at the top of the locking / unlocking member 10 interacts with the lifting unlocking body 5. According to the principle of force decomposition in mechanics, the pressure exerted by the lifting unlocking body 5 on the locking / unlocking member 10 will decompose into a component force pointing inward towards the first receiving groove 9. Under the action of this component force, the locking / unlocking member 10 moves a certain distance into the first receiving groove 9, which is denoted as the second distance. Since the size of the lifting unlocking body 5 is larger than the size of the lifting lock control body 4, the pressure component force on the locking / unlocking member 10 is greater, causing its second distance of movement to be greater than the first distance it moved when interacting with the lifting lock control body 4. When the second distance that the locking / unlocking member 10 moves reaches a certain level, the locking / unlocking member 10 will move completely into the first receiving groove 9.

[0035] Specifically, when the locking / unlocking component 10 has fully moved into the first receiving groove 9, the limiting groove 16 on the locking / unlocking component 10 is precisely aligned with the second receiving groove 12 of the lifting tray 2. At this time, under the elastic force of the return spring 13, the limiting component 17 quickly inserts into the limiting groove 16, thereby achieving the limiting and locking of the locking / unlocking component 10. After the locking / unlocking component 10 is stably restricted within the first receiving groove 9, the lifting tray 2 loses the limiting constraint from the locking / unlocking component 10 and can freely fall to the initial position within the lifting guide groove 6 by its own gravity. Furthermore, during the descent of the lifting tray 2, since the locking / unlocking component 10 is completely within the first receiving groove 9, it will no longer be blocked or obstructed by the lifting lock control body 4 and the lifting unlocking body 5, ensuring the smoothness of the descent process.

[0036] Specifically, after completing the fire emergency operation and entering the preparation stage for the next use, the operator can manually pull the limiting member 17 upward. After the limiting member 17 leaves the limiting groove 16, the locking and unlocking member 10, under the action of the elastic potential energy stored in the elastic member 15, extends at least partially out of the first receiving groove 9, returning to the initial state where it can cooperate with the lifting lock control body 4 to achieve limiting again, thus preparing for the next normal use.

[0037] Please refer to Figure 4 In some embodiments of this application, the lifting knob 14 is connected to the end of the limiting member 17 by assembly, and the lifting knob 14 is located outside the second receiving groove 12. The outer contour dimension of the lifting knob 14 is designed to be larger than the inner contour dimension of the second receiving groove 12. This dimensional difference ensures that the lifting knob 14 cannot enter the interior of the second receiving groove 12. The lifting knob 14 is always kept in a position that is convenient for the operator to directly contact and operate. By applying force to the lifting knob 14, the limiting member 17 can be easily driven to move, so as to realize the relevant control functions of the dual-state locking and unlocking assembly.

[0038] Please refer to Figure 1 In some embodiments of this application, the connection structure between the assist push button 8 and the lifting tray 2 is stable. The main function of the assist push button 8 is to provide a point of leverage for the operator to push the lifting tray 2, effectively reducing the force required to push the lifting tray 2, and assisting the lifting tray 2 to smoothly adjust its vertical position within the lifting guide groove 6, thereby improving the convenience and efficiency of operating the entire wall-mounted fire extinguisher bracket 3.

[0039] Working principle: The wall-mounted fire extinguisher bracket 3 is based on the wall-mounted base plate 1, which is stably installed on the wall and provides a support platform. The lifting guide groove 6 on the base plate is the key track, which limits the vertical movement path and range of the lifting support plate 2. The lifting support plate 2 carries the fire extinguisher bracket 3, realizing the vertical position adjustment of the fire extinguisher. The avoidance groove 7 avoids interference with the lifting lock control body 4 and the lifting unlocking body 5, ensuring smooth movement, while the first receiving grooves 9 on both sides are used to install the dual-state locking and unlocking components.

[0040] In normal operation, when the lifting platform 2 moves upward, it causes the locking / unlocking component 10 in the connected dual-state locking / unlocking assembly to rise synchronously. The inclined surface at the top of the locking / unlocking component 10 contacts the lifting locking control body 4. According to the principle of force decomposition, the pressure exerted by the lifting locking control body 4 on the locking / unlocking component 10 generates a component force that propels the locking / unlocking component 10 into the first receiving groove 9, moving it a first distance into the groove, but not completely inside. When the locking / unlocking component 10 passes the lifting locking control body 4, the pressure disappears, and the elastic element 15 (spring, elastic rubber, or elastic metal sheet, etc.) releases its elastic potential energy, causing the locking / unlocking component 10 to bounce back to its initial position. At this time, the straight structure below the locking / unlocking component 10 interacts with the lifting locking control body 4, preventing the lifting locking control body 4 from moving downward. Because the movement of the lifting locking control body 4 is related to that of the lifting platform 2, it restricts the descent of the lifting platform 2, stabilizing it at a set height and preventing minors from touching the fire extinguisher bracket 3.

[0041] In the event of an emergency such as a fire, the lifting platform 2, which is already locked at a high position, requires further operation. The operator continues to push the lifting platform 2 upwards, causing the locking and unlocking component 10 to move again to the position corresponding to the lifting and unlocking body 5. The pressure component of the lifting and unlocking body 5 on the locking and unlocking component 10 causes the locking and unlocking component 10 to move a greater second distance into the first receiving groove 9 until it is fully inserted into the groove. At this time, the limiting groove 16 on the locking and unlocking component 10 aligns with the second receiving groove 12 of the lifting platform 2, and the limiting component 17, under the action of the return spring 13, inserts into the limiting groove 16, locking the locking and unlocking component 10 in the groove. The lifting platform 2, no longer limited by the locking and unlocking component 10, falls freely to the lowest point under the action of gravity, making it convenient for adults to quickly retrieve the fire extinguisher. After the operation is completed, before the next use, manually pull up the lifting unlock lever and other components connected to the limiting member 17 so that the limiting member 17 leaves the limiting groove 16. The elastic member 15 will then eject at least part of the locking and unlocking member 10 from the first receiving groove 9, restoring it to the initial state where it can be locked again, ready for the next cycle of use.

It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
