TECHNICAL FIELD
[0001] The present application relates to the technical field of fire-fighting equipment, in particular to a wall-mounted clamping device for fire extinguishers. BACKGROUND
[0002] The existing fire extinguisher hanger mostly adopts a belt type structure, that is, the fire extinguisher is fixed on the hanger by a belt. Although this hanger has a simple structure and low manufacturing cost, it has obvious deficiencies in actual use, especially in emergency situations such as fire, because the personnel are nervous and operate in a hurry, it is often difficult to quickly and accurately untie the belt, resulting in the extension of the time for taking the fire extinguisher and possibly missing the best fire extinguishing opportunity. CONTENT OF THE INVENTION
[0003] The present application solves the problem that the existing fire extinguisher hanger is often difficult for the operator to quickly and accurately untie the belt in emergency situations such as fire, resulting in the extension of the time for taking the fire extinguisher and possibly missing the best fire extinguishing opportunity.
[0004] To solve the above technical problems, the present application provides a wall-mounted clamping device for fire extinguishers, which comprises a seat plate, a clamping sleeve symmetrically arranged on the top of the seat plate, a self-tightening assembly arranged in the interior of the seat plate and connected with the clamping sleeve, and the self-tightening assembly utilizes the gravity of the fire extinguisher itself as a power source to realize the automatic clamping and longitudinal pulling and separating functions of the clamping sleeve on the fire extinguisher. The self-tightening assembly comprises a bracket plate, a support arm and a connecting rod. The bracket plate is sleeved on the inner side of the seat plate and forms a sliding fit with the seat plate. The support arm is arranged on the upper end of the inner side of the seat plate. The middle part of the support arm can rotate around the seat plate. The top end of the support arm is connected with the clamping sleeve. The bottom end of the support arm is connected with the bracket plate through the connecting rod.
[0005] Since the clamping type hanger of the present application is designed with a clamping sleeve and a self-tightening assembly, the automatic clamping and loosening of the clamping sleeve can be realized by utilizing the gravity of the fire extinguisher itself and the elastic force of the spring through the swinging of the connecting rod mechanism and the support arm, ensuring the stable fixation of the fire extinguisher on the hanger and the quick release when needed, thereby solving the problem that the existing fire extinguisher hanger is often difficult for the operator to quickly and accurately untie the belt in emergency situations such as fire, resulting in the extension of the time for taking the fire extinguisher and possibly missing the best fire extinguishing opportunity.

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example
[0015] This application relates to a wall-mounted clamping device for fire extinguishers, such as... Figures 1-7 As shown, the bracket includes a base plate 4, which is U-shaped and serves as the main support structure of the bracket. Its opening faces the side where the fire extinguisher 1 is placed. Hanging strips 5 are symmetrically arranged on one side of the base plate 4 and connected to the base plate 4. Both ends of the hanging strips 5 are provided with hanging holes for wall mounting, making it easy to fix the bracket to the wall or other support. Clips 2 are symmetrically arranged on the top of the base plate 4 and are designed to open and close, used to hold the body of the fire extinguisher 1. The opening and closing method of the clips 2 can be mechanical, spring-loaded, or other methods that can achieve automatic clamping and manual or automatic release. A self-tightening component 3 is arranged inside the base plate 4 and connected to the clips 2. The self-tightening component 3 uses the weight of the fire extinguisher 1 as a power source. When the fire extinguisher 1 is placed in the clips 2, the clips 2 automatically clamp the body of the fire extinguisher 1 through the action of the self-tightening component 3, thus fixing it. When it is necessary to remove the fire extinguisher 1, it can be easily removed by overcoming the clamping force of the self-tightening component 3. The operation is simple and quick.
[0016] In use, the fire extinguisher 1 is placed into the clamping sleeve 2 of the seat plate 4, and the self-tightening assembly 3 is subjected to the gravity of the fire extinguisher 1 itself, so that the clamping sleeve 2 automatically clamps the bottle body of the fire extinguisher 1 to achieve stable fixation. When the fire extinguisher 1 needs to be taken out, the user only needs to lift the fire extinguisher 1 upward to overcome the clamping force of the self-tightening assembly 3, so that the clamping sleeve 2 is automatically opened to allow the fire extinguisher 1 to be smoothly taken out. The entire process does not need to untie any belt or buckle, greatly simplifies the operation steps, and improves the taking speed of the fire extinguisher 1.
[0017] The self-tightening assembly 3 includes a shelf plate 9, a support arm 7, a connecting rod 8, a supporting plate 10, and a spring 11. The shelf plate 9 is in the shape of a U, is sleeved on the inner side of the seat plate 4, and is in sliding cooperation with the seat plate 4. The shelf plate 9 serves as the main supporting structure of the self-tightening assembly 3, carries other components, and transmits the gravity of the fire extinguisher 1. The support arm 7 is arranged on the upper end of the inner side of the seat plate 4 in the shape of an obtuse angle, the middle part of which can rotate around the seat plate 4 (not shown, a rotating shaft is arranged at the connection between the support arm 7 and the seat plate 4), the top end of the support arm 7 is connected with the clamping sleeve 2, and when the support arm 7 rotates, the clamping sleeve 2 is moved. The bottom end of the support arm 7 is connected with the shelf plate 9 through the connecting rod 8 to form a connecting rod 8 mechanism, so as to realize power transmission between the shelf plate 9 and the support arm 7. When the shelf plate 9 moves, the support arm 7 is driven to rotate through the connecting rod 8. The supporting plate 10 is arranged directly above the shelf plate 9 and serves as a bottom support. When the fire extinguisher 1 is placed, the bottom of the fire extinguisher 1 abuts against the supporting plate 10. The design of the supporting plate 10 ensures that the fire extinguisher 1 can be stably supported when placed, so as to avoid impact caused by the direct falling of the fire extinguisher 1 due to gravity. The spring 11 is arranged between the seat plate 4 and the shelf plate 9. When the shelf plate 9 moves downward, the spring 11 is compressed to store energy. When the fire extinguisher 1 is taken out, the spring 11 releases the stored energy to push the shelf plate 9 to rise and reset, and then drives the support arm 7 and the clamping sleeve 2 to separate through the connecting rod 8, so as to realize the rapid release of the fire extinguisher 1. The shelf plate 9 is symmetrically arranged with slide pins 12 on both sides, and the inner side of the seat plate 4 is symmetrically arranged with slide grooves 6 for the slide pins 12 to slide. The slide pins 12 slide in the slide grooves 6 to guide the vertical up-and-down movement of the shelf plate 9, so as to ensure the stability and accuracy of the movement. In order to reduce the friction resistance between the slide pins 12 and the slide grooves 6, a rotating sleeve (not shown) can be additionally arranged on the outer side of the slide pins 12, and snap springs (not shown) can be additionally arranged at the axial ends of the slide pins 12 to realize axial anti-dropping and ensure the stable sliding of the slide pins 12 in the slide grooves 6 without falling off.
[0018] When the fire extinguisher 1 is placed along the vertical direction of the shelf plate 9, the bottom of the fire extinguisher 1 abuts against the supporting plate 10. At this moment, the gravity of the fire extinguisher 1 acts on the surface of the supporting plate 10, the supporting plate 10 drives the shelf plate 9 to move vertically downward along the slide grooves 6 through the slide pins 12. In the process of moving downward, the shelf plate 9 drives the support arm 7 to swing around the seat plate 4 through the connecting rod 8, and at the same time, the spring 11 starts to be compressed to store energy. The support arm 7 drives the clamping sleeve 2 at the upper end thereof to move close to the side wall of the fire extinguisher 1 under the driving of the connecting rod 8, until stable abutment is formed. In this way, the fire extinguisher 1 is clamped and fixed on the hanger in a self-tightening manner.
[0019] When it is needed to take out the fire extinguisher 1, only need to pull the fire extinguisher 1 along the vertical direction upward, at this moment, the shelf plate 9 loses the gravity of the fire extinguisher 1, the spring 11 releases the accumulated force, pushes the shelf plate 9 to rise and reset, in the process of rising, the shelf plate 9 drives the support arm 7 to swing reversely through the connecting rod 8, the jacket 2 is separated accordingly, realizing the quick separation between the fire extinguisher 1 and the jacket 2.
[0020] In order to avoid the abrasion of the surface of the fire extinguisher 1 when the jacket 2 and the side wall of the fire extinguisher 1 abut, a three-layer structure design of the outer sleeve 15, the inner sleeve 14 and the lining plate 13 is adopted, the outer sleeve 15 is arranged outside the support arm 7, as the outer layer structure of the jacket 2, plays the role of protection and support, the material of the outer sleeve 15 can be selected to have certain strength and wear resistance, to ensure the overall stability and durability of the jacket 2, the inner sleeve 14 is concentrically arranged inside the outer sleeve 15, in contact with the inner wall of the support arm 7, the material of the inner sleeve 14 can be selected to be relatively soft or have certain elasticity, to adapt to different shapes and sizes of the fire extinguisher 1, and to ensure the tightness when clamping, the lining plate 13 is arranged inside the inner sleeve 14, uniformly and intervally arranged along the circumferential direction, in direct contact with the outer wall of the fire extinguisher 1, the material of the lining plate 13 is selected to be softer or have better lubricity than the inner sleeve 14 and the outer sleeve 15, such as rubber, plastic or other low-friction lining plate 13, the design of the lining plate 13 can effectively reduce the hard friction loss between the jacket 2 and the side wall of the fire extinguisher 1, and protect the surface of the fire extinguisher 1 from being abraded.
[0021] The operation of putting in the fire extinguisher 1: hold the fire extinguisher 1 vertically, align the opening position of the jacket 2, gently put the bottom of the fire extinguisher 1 on the supporting plate 10, at this moment, the gravity of the fire extinguisher 1 starts to act on the supporting plate 10, with the gradual lowering of the fire extinguisher 1, the supporting plate 10 is subjected to the gravity, drives the shelf plate 9 to move vertically downward along the sliding groove 6, the downward movement of the shelf plate 9 transmits power through the connecting rod 8 mechanism, makes the support arm 7 swing around its rotating shaft, and further drives the inner sleeve 14 and the outer sleeve 15 to close to the side wall of the fire extinguisher 1, when the lining plate 13 is in contact with the side wall of the fire extinguisher 1, due to the low friction coefficient material of the lining plate 13, the surface of the fire extinguisher 1 will not be abraded, at the same time, the spring 11 of the self-tightening assembly 3 is compressed to accumulate force, to ensure that the jacket 2 tightly clamps the fire extinguisher 1.
[0022] The operation of taking out the fire extinguisher 1: hold the handle or bottle body of the fire extinguisher 1 with hand, vertically lift up, with the lifting of the fire extinguisher 1, the supporting plate 10 loses the gravity of the fire extinguisher 1, the shelf plate 9 starts to rise and reset under the release of the accumulated force of the spring 11, the rising of the shelf plate 9 transmits power through the connecting rod 8 mechanism, makes the support arm 7 swing reversely, and further drives the inner sleeve 14 and the outer sleeve 15 to separate, the clamping force between the jacket 2 and the side wall of the fire extinguisher 1 gradually decreases, when the jacket 2 is completely opened, the fire extinguisher 1 can be easily taken out from the hanging rack, the whole process is quick and smooth.
[0023] The clamping type hanger of the present application utilizes the self-gravity of the fire extinguisher 1 and the elastic force of the spring 11 to realize the automatic clamping and loosening of the clamping sleeve 2 through the swing of the connecting rod 8 mechanism and the supporting arm 7, which ensures the stable fixation of the fire extinguisher 1 on the hanger and the quick release when needed. The lining plate 13 in the clamping sleeve 2 is made of a material with low friction coefficient, which effectively reduces the friction loss between the clamping sleeve 2 and the side wall of the fire extinguisher 1 and protects the surface of the fire extinguisher 1 from being worn.
