Description

Technical Field

[0001] This invention belongs to the field of fire extinguisher processing technology, specifically, this invention relates to a fire extinguisher spraying device. Background Technology

[0002] As a type of fire-fighting equipment, fire extinguishers are usually painted red to make them more visible and easier to spot. Since the main body of a fire extinguisher is cylindrical, existing spraying equipment typically uses a threaded structure to screw the canister onto a boom for rotational spraying.

[0003] A specification published on September 15, 2023, with application number 202310657079.4, discloses an automatic spraying device for fire extinguisher cylinders. The device includes a machine body, a spraying chamber fixedly installed inside the machine body, a drying chamber fixedly installed inside the machine body at the end of the spraying chamber, a feeding mechanism fixedly installed at the front of the machine body, a vertically sliding nozzle inside the spraying chamber, and a discharge ramp fixedly installed below the end of the drying chamber. This device integrates fire extinguisher loading, hoisting, spraying, drying, and collection, enabling automatic operation after loading without manual intervention. It achieves fully automatic spraying of the fire extinguisher cylinders, accurately aligning the cylinder with the insertion rod, and using a hoisting mechanism to fix and hoist the internal parts of the fire extinguisher, avoiding uneven spraying of the cylinder surface and unsprayed areas at the contact points with the fixing clamps that can occur with external clamping spraying.

[0004] In existing technologies, using external clamping devices for holding canisters can affect normal spraying, while threaded fixing requires manual tightening of the canister. If the paint is not dry, it will result in unqualified surface spraying. In the aforementioned existing technologies, internal clamping is used, but in actual production, operators cannot guarantee that a fire extinguisher canister can be fixed on all clamps. When clamps without canisters are passed by the spraying device, paint will be sprayed onto the clamps, and the paint will stick the equipment structure together, affecting normal use. Summary of the Invention

[0005] The present invention aims to provide a fire extinguisher spraying device that ensures normal spraying effect without affecting the normal use of the clamp.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a fire extinguisher spraying device, comprising a boom and a tank, wherein the bottom end of the boom is provided with an inner clamping component for fixing the tank, and the boom is provided with a sleeve for shielding the inner clamping component.

[0007] The inner clamping assembly includes an insertion rod disposed at the end of the lifting rod, and an openable abutment rod is hinged to the outside of the insertion rod. The distance between the end of the abutment rod and the insertion rod after the end of the abutment rod is opened is the radius of the bottle mouth of the can.

[0008] The movable end of the abutment rod is located at the bottom, and a friction pad is provided on the side of the abutment rod that contacts the inner wall of the tank. The friction pad is a rubber pad.

[0009] A push rod is provided between the abutment rod and the insertion rod. A slider is slidably connected to the insertion rod. One end of the push rod is hinged to the slider, and the other end of the push rod is hinged to the middle of the abutment rod.

[0010] The insertion rod is provided with a sliding groove that cooperates with the slider. The slider is provided with a pull rod that is slidably connected in the sliding groove. Limiting parts are provided on both sides of the pull rod, and limiting grooves that cooperate with the limiting parts are provided on both sides of the sliding groove.

[0011] The sleeve has an internal ring plate, and the end of the pull rod has a push plate. The ring plate is located below the push plate, and the ring plate and the push plate are staggered on the vertical plane.

[0012] A sealing ring is fitted on the outer side of the insertion rod, and a bottom plate with a diameter larger than the inner diameter of the sealing ring is provided at the bottom end of the insertion rod. A top ring is provided at the top end of the sleeve, and the top ring is fitted on the outer side of the lifting rod. The top ring is set along the inner edge of the top end of the sleeve. The lifting rod is inverted T-shaped, and the inner diameter of the top ring is smaller than the diameter of the bottom end of the lifting rod.

[0013] The insertion rod is provided with a snap-fit ​​component, and the inner side of the sleeve is provided with a push block. The push block and the snap-fit ​​component are located on the same vertical axis, and the snap-fit ​​component is a gate switch type structure.

[0014] The snap-fit ​​component includes a push button hinged to the insertion rod. The surface of the insertion rod is provided with a recess, and the push button is embedded in the recess. Positioning parts are provided on both sides of the push button, and positioning grooves that cooperate with the positioning parts are provided in the recess.

[0015] There are two sets of positioning grooves, which are located at the upper and lower ends of the inner side of the insert. The positioning part is a semi-circular protrusion structure that protrudes from the push button and is an elastic element.

[0016] The technical effect of this invention is as follows: When the can needs to be sprayed, the can is pushed up along the insertion rod, and the inner clamping assembly unfolds, thereby fixing the can and enabling the can to be sprayed normally. If the can is not installed in time, the sleeve is fitted on the outside of the insertion rod and the inner frame assembly, which can protect the inner structure from being sprayed with paint, thus preventing the internal fixing structure from sticking together with paint and becoming unusable.

[0019] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0020] Please see Figure 1-5 A fire extinguisher spraying device includes a boom 1 and a tank 2. The bottom end of the boom 1 is provided with an inner clamping assembly for fixing the tank 2, and the boom 1 is provided with a sleeve 3 for shielding the inner clamping assembly. When the tank 2 needs to be sprayed, the inner clamping assembly unfolds by pushing the tank 2 up along the insertion rod 4, thereby fixing the tank 2 and allowing the tank 2 to be sprayed normally. At this time, the sleeve 3 rises along the insertion rod 4 and is located at the upper part, which does not affect the normal unfolding of the inner clamping assembly and the normal fixing of the tank 2. When the tank 2 is not installed in time, the sleeve 3 is held at the lower part under the action of gravity. The sleeve 3 is fitted on the outside of the insertion rod 4 and the inner frame assembly, which can protect the inner structure from being sprayed with paint, so as to prevent the internal fixing structure from being stuck together by paint and becoming unusable.

[0021] The inner clamping assembly includes an insertion rod 4 located at the end of the lifting rod 1. An openable abutment rod 5 is hinged to the outside of the insertion rod 4. The distance between the end of the abutment rod 5 and the insertion rod 4 after it is opened corresponds to the radius of the bottle mouth of the can body 2. The insertion rod 4 is inserted into the can body 2. The abutment rod 5, which is circumferentially arranged and opens inside the can body 2, abuts against the inner wall of the can body 2 as an umbrella post after it is opened. The abutment rod 5 supports the can body 2. Since the abutment rod 5 is located inside the can body 2, it will not affect the normal spraying of the surface of the can body 2. At this time, since the can body 2 is fitted outside the insertion rod 4, the can body 2 pushes the sleeve 3 to rise. The sleeve 3 is located above the can body 2 and will not block the outer surface of the can body 2.

[0022] The movable end of the abutment rod 5 is located at the bottom. A friction pad 6, which is a rubber pad, is provided on the side of the abutment rod 5 that contacts the inner wall of the tank 2. This ensures that the abutment rod 5 can be opened into an umbrella shape with the opening facing downwards when unfolded, and that the abutment rod 5 can contact the inner wall of the tank 2 with a larger area, increasing the friction. At the same time, the rubber friction pad 6 on the surface of the abutment rod 5 can improve the friction between the abutment rod 5 and the inner wall of the tank 2. In this way, when the lifting rod 1 rotates, the tank 2 can be rotated together by the insertion rod 4 and the abutment rod 5, ensuring that the entire surface of the tank 2 can be sprayed, thus ensuring the uniformity of the spraying.

[0023] A push rod 7 is provided between the abutment rod 5 and the insertion rod 4. A slider 8 is slidably connected to the insertion rod 4. One end of the push rod 7 is hinged to the slider 8, and the other end of the push rod 7 is hinged to the middle of the abutment rod 5. The push rod 7 is used to push the abutment rod 5 to unfold. By pushing the slider 8, the end of the push rod 7 is pushed to move. When the end of the push rod 7 moves, the other end of the push rod 7 will push the abutment rod 5 to unfold, thereby achieving the purpose of fixing the tank 2.

[0024] The insertion rod 4 is provided with a groove that cooperates with the slider 8. The slider 8 is provided with a pull rod 18, which is slidably connected in the groove. Limiting parts are provided on both sides of the pull rod 18, and limiting grooves that cooperate with the limiting parts are provided on both sides of the groove. The pull rod 18 is moved by the sleeve 3, thereby causing the abutment rod 5 to unfold. After the can body 2 is put on, the sleeve 3 and the pull rod 18 are pushed up, thereby causing the end of the push rod 7 connected to the slider 8 to move up, thereby achieving the purpose of opening the abutment rod 5.

[0025] The sleeve 3 has an inner ring plate 9, and the end of the pull rod 18 has a push plate 10. The ring plate 9 is located below the push plate 10, and the ring plate 9 and the push plate 10 are staggered on the vertical plane. The ring plate 9 is separated from the push plate 10 to ensure that the sleeve 3 has a certain margin during the upward process. This avoids the situation where the sleeve 3 cannot be smoothly fitted onto the insertion rod 4 before the abutting rod 5 is inserted into the tank 2 due to the upward opening of the abutting rod 5. This prevents the problem of the abutting rod 5 opening before entering the tank 2. As the sleeve 3 rises, the ring plate 9 on the inner side of the sleeve 3 intersects with the push plate 10. When the sleeve 3 drives the ring plate 9 to rise, the ring plate 9 is located below the push plate 10. The ring plate 9 will push the push plate 10 to rise, thereby driving the end of the push rod 7 connected to the slider 8 to move upward, thereby achieving the purpose of opening the abutting rod 5.

[0026] A sealing ring 11 is fitted on the outer side of the insertion rod 4. The bottom end of the insertion rod 4 is provided with a bottom plate 12 with a diameter larger than the inner diameter of the sealing ring 11. The top end of the sleeve 3 is provided with a top ring 13, which is fitted on the outer side of the lifting rod 1. The top ring 13 is set along the inner edge of the top end of the sleeve 3. The lifting rod 1 is inverted T-shaped, and the inner diameter of the top ring 13 is smaller than the diameter of the bottom end of the lifting rod 1. When the can body 2 is fitted onto the insertion rod 4, the end of the sealing ring 11 abuts against the opening of the can body 2 under the action of gravity. At the same time, the inner edge of the sealing ring 11 protrudes outward, forming a boss shape, which can prevent the sealing ring 11 from shifting. The sealing ring 11 can reduce the amount of paint entering the can body 2 during spraying. At the same time, the inverted T-shaped lifting rod 1 and the top ring 13 can prevent the sleeve 3 from falling off the outside of the insertion rod 4 and can ensure that the sleeve 3 can cover part of the insertion rod 4, preventing paint from being sprayed onto the insertion rod 4.

[0027] The insertion rod 4 is equipped with a snap-fit ​​component, and the inner side of the sleeve 3 is equipped with a push block 14. The push block 14 and the snap-fit ​​component are located on the same vertical axis. The snap-fit ​​component is a gate switch type structure. The snap-fit ​​component is used to restrict the position of the sleeve 3, so that the sleeve 3 has two states: an upper position and a lower position, which correspond to the two situations of fixing the tank 2 or blocking the insertion rod 4, respectively. The lifting and lowering of the sleeve 3 drives the switching of the two states of the snap-fit ​​component. At the same time, the snap-fit ​​component can also restrict the position of the sleeve 3, so as to achieve the effect of switching the position of the sleeve 3.

[0028] The snap-fit ​​component includes a push button 15 hinged to the insertion rod 4. The surface of the insertion rod 4 is provided with a recess, and the push button 15 is embedded in the recess. Positioning parts 16 are provided on both sides of the push button 15, and positioning grooves 17 that cooperate with the positioning parts 16 are provided in the recess. The position of the push button 15 is fixed by the cooperation of the positioning parts 16 and the positioning grooves 17.

[0029] There are two sets of positioning grooves 17, which are located at the upper and lower ends of the inner side of the insert. The positioning part 16 is a semi-circular protrusion structure that protrudes from the push button 15. The positioning part 16 is an elastic element. The elastic element is easy to push and is provided with two sets of positioning grooves 17 to fix the push button 15 in the upper and lower positions.

[0030] Working principle: Before spraying, the operator places the can body 2 on the outside of the insertion rod 4. Simultaneously, the operator moves the sleeve 3 upwards while placing the can body 2 on the outside of the can body 2 until the entire abutment rod 5 is inserted into the can body 2. Then, the operator continues to push the sleeve 3 upwards, causing the pull rod 18 to move, thereby unfolding the abutment rod 5. After the can body 2 is placed on top, pushing the sleeve 3 and pull rod 18 upwards causes the end of the push rod 7 connected to the slider 8 to move upwards, pushing the slider... 8. Push the end of push rod 7 to move. When the end of push rod 7 moves, push rod 7 rotates, and the other end of push rod 7 pushes the abutment rod 5 to unfold. After the abutment rod 5 unfolds, it forms an umbrella-shaped post that abuts against the inner wall of the can 2. The abutment rod 5 supports the can 2, and since the abutment rod 5 is located inside the can 2, it will not affect the normal spraying of the surface of the can 2. At this time, since the can 2 is fitted outside the insertion rod 4, the can 2 pushes the sleeve 3 to rise. The sleeve 3 is located above the can 2, and it will not block the outside of the can 2. On the surface of the abutment rod 5, a rubber friction pad 6 is added to increase the friction between the abutment rod 5 and the inner wall of the tank 2. This allows the tank 2 to rotate together with the insertion rod 4 and the abutment rod 5 when the lifting rod 1 rotates, ensuring that the entire surface of the tank 2 can be sprayed, guaranteeing uniform spraying. Furthermore, when the sleeve 3 rises, the push block 14 inside the sleeve 3 pushes the push button 15 upwards, causing the positioning part 16 to be pushed out from the lower positioning groove 17 and into the upper positioning groove 17. Inside, the push button 15 is positioned. At this time, the push block 14 inside the sleeve 3 is restricted by the push button 15. The sleeve 3 cannot descend under the action of gravity and will not hit the opening of the can 2. When the can 2 is fitted onto the insertion rod 4, the end of the sealing ring 11 abuts against the opening of the can 2 under the action of gravity. At the same time, the inner edge of the sealing ring 11 protrudes outward and is in the shape of a boss, which can prevent the sealing ring 11 from shifting. The sealing ring 11 can reduce the situation where paint enters the can 2 during spraying. When the tank body 2 is removed, the sleeve 3 is pushed down. When the sleeve 3 is lowered, the push plate 10 on the slider 8 is no longer supported. Under the action of gravity, the slider 8 is lowered, the push rod 7 is reset, the abutment rod 5 is reset, the abutment rod 5 no longer supports the tank body 2, the tank body 2 can be removed, and the various structures are reset under the action of gravity. When the canister 2 is not attached, the sleeve 3 falls naturally under the action of gravity. The top ring 13 at the top of the sleeve 3 is supported by the lifting rod 1 and is fitted on the outside of the insertion rod 4. This can protect the inner insertion rod 4 and prevent paint from being sprayed directly onto the insertion rod 4, causing the structure on the insertion rod 4 to be glued together by the paint.

[0031] The technical effect of the present invention is as follows: When it is necessary to spray the can 2, the can 2 is pushed up along the insertion rod 4, and the inner clamping assembly is unfolded, thereby fixing the can 2 and enabling the can 2 to be sprayed normally. When the can 2 is not installed in time, the sleeve 3 is fitted on the outside of the insertion rod 4 and the inner frame assembly, which can protect the inner structure from being sprayed with paint, so that the internal fixing structure can not be used normally due to paint sticking together.

[0032] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
