Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishers, and more particularly to an anti-counterfeiting safety structure of a fire extinguisher valve. Background Art

[0002] Most fire extinguishers currently on the market have an anti-counterfeiting structure installed on the safety portion of the valve to prevent counterfeiting. This structure serves as a safety and anti-counterfeiting measure. After the extinguisher is used, the user cannot refill it and repair it themselves. Instead, the extinguisher must be returned to the original manufacturer for refilling and repair to ensure the quality and effectiveness of the extinguisher. Existing valve safety and anti-counterfeiting structures are often designed to consist of a safety pin and a specially designed anti-counterfeiting plastic pin. Installation is accomplished by machining a small hole in the safety pin, through which the plastic pin is inserted. Due to the small size of the safety pin, machining the hole is difficult.

[0003] The prior art discloses an anti-counterfeiting safety structure for fire extinguisher valves, comprising a safety pin and an anti-counterfeiting label. The safety pin includes an insert pin and a pull ring. The anti-counterfeiting label is affixed to the end of the insert pin away from the pull ring and features a protrusion oriented perpendicular to the pin's axis. The protrusion is marked with anti-counterfeiting information. While this structure eliminates the need for machining a small hole in the safety pin, simplifying fabrication, the label's durability is poor due to the adhesive required to connect the label to the safety pin. Furthermore, after being left outdoors for a period of time, the label is prone to wear, fading, or falling off, making it difficult to provide anti-counterfeiting protection. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art anti-counterfeiting safety structure in terms of poor durability, and to provide a fire extinguisher valve anti-counterfeiting safety structure that is less difficult to manufacture and has better durability.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] Provided is an anti-counterfeiting safety structure for a fire extinguisher valve, comprising a lifting and pressing handle and a safety bolt for controlling the release of a fire extinguishing agent, the safety bolt comprising an insertion pin and a pull ring connected in sequence, the lifting and pressing handle being provided with a through hole for the insertion pin to pass through, and an anti-counterfeiting component for preventing the insertion pin from separating from the through hole, the anti-counterfeiting component comprising an anti-counterfeiting buckle marked with anti-counterfeiting information, a cable tie, and a lock buckle for locking the cable tie, the anti-counterfeiting buckle, the lock buckle, and the cable tie being connected in sequence; the cable tie passes through the pull ring, is wrapped around the outside of the lifting and pressing handle, and is connected to the lock buckle.

[0007] The fire extinguisher valve anti-counterfeiting safety structure of the present invention prevents the valve from being accidentally opened or damaged before using the fire extinguisher product. The insertion pin of the safety bolt is inserted into the through hole, which plays a protective role and reduces the safety risk of the fire extinguisher during storage and transportation. The cable tie is then passed through the pull ring and arranged on the outside of the lifting and pressing handle. After wrapping around the outside of the lifting and pressing handle, the cable tie is tightened through the lock buckle, tightly connecting the anti-counterfeiting component with the lifting and pressing handle and the insertion pin. The anti-counterfeiting buckle on the anti-counterfeiting component is marked with anti-counterfeiting information, so that the safety structure has good anti-counterfeiting performance. After using the fire extinguisher product, if the anti-counterfeiting cable tie is damaged, the user can only hand it over to the original manufacturer for after-sales service, which helps to combat counterfeit and shoddy products. By setting up the anti-counterfeiting component for anti-counterfeiting, there is no need to process small holes on the safety bolt, and the processing difficulty is relatively low; using the anti-counterfeiting buckle, cable tie and lock buckle at the same time for anti-counterfeiting can adapt to outdoor environments and has good durability.

[0008] Furthermore, the lifting and pressing handle includes a rotating portion and a pressing portion connected in sequence, the through hole is located in the rotating portion, and the cable tie is radially wrapped around the outside of the rotating portion along the insertion pin, so as to tightly bind the rotating portion of the lifting and pressing handle, thereby preventing the lifting and pressing handle from loosening during transportation.

[0009] Furthermore, the length of the insertion pin is greater than the width L of the lifting and pressing handle. The lifting and pressing handle is provided with a mounting seat for connecting to the fire extinguisher, the mounting seat being connected to the rotating portion, and the cable tie being located between the insertion pin and the mounting seat. The cable tie is positioned to prevent it from being removed from other positions of the lifting and pressing handle, thereby allowing the anti-counterfeiting component to better perform its anti-counterfeiting function.

[0010] Furthermore, the anti-counterfeiting component further includes an anti-slip strip, the two ends of which are respectively connected to the lock buckle and the cable tie, and the anti-slip strip abuts against the lifting and pressing handle to enhance the friction between the anti-counterfeiting component and the lifting and pressing handle to prevent the anti-counterfeiting component from falling.

[0011] Furthermore, the pull ring is configured as a complete closed structure, which prevents the cable tie from being removed from the gap of the pull ring, thereby enabling the anti-counterfeiting component to better play an anti-counterfeiting role.

[0012] Furthermore, the anti-counterfeiting component is fixedly connected to the pull ring. By making the anti-counterfeiting component fixedly connected to the pull ring, the anti-counterfeiting component and the safety pin can be always connected after use, thereby facilitating the recovery of the anti-counterfeiting component while recovering the safety pin.

[0013] Furthermore, the anti-counterfeiting component is integrally formed, which prevents the anti-counterfeiting buckle from being separated from the rest of the anti-counterfeiting component, and enables the anti-counterfeiting component to better play an anti-counterfeiting role.

[0014] Furthermore, the cable tie includes a strap body and a positioning buckle. The positioning buckle is provided on the strap body and is coaxial with the strap body. The strap body is connected to the locking buckle. The locking buckle has a through hole. The locking buckle is provided with multiple elastic pieces facing the center of the through hole and connected to the inner wall of the through hole. The positioning buckle abuts against the elastic pieces. The strap body passes through the through hole, is wrapped around the lifting and pressing handle, and then the cable tie and locking buckle are firmly connected via the positioning buckle and elastic pieces.

[0015] Furthermore, the positioning buckles are provided in plurality along the axial direction of the belt body, so as to flexibly adjust the tightness of the binding lifting and pressing handles.

[0016] Furthermore, the outer diameter of the positioning buckle gradually decreases from the lock buckle to the belt body, making it easier to pass the positioning buckle through the through hole.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The utility model provides an anti-counterfeiting safety structure for a fire extinguisher valve. Anti-counterfeiting is achieved by setting an anti-counterfeiting component, without the need to process a small hole on the safety bolt, and the processing difficulty is relatively low. At the same time, anti-counterfeiting buckles, cable ties and lock buckles are used for anti-counterfeiting, which can adapt to outdoor environments and has good durability.

[0019] 2. The utility model provides an anti-counterfeiting safety structure for a fire extinguisher valve. By providing an anti-counterfeiting component, the rotating part of the lifting and pressing handle can be tightly bound, thereby preventing the lifting and pressing handle from becoming loose during transportation. At the same time, the cable tie is positioned by the safety bolt and the mounting seat to prevent the cable tie from being removed from other positions of the lifting and pressing handle, so that the anti-counterfeiting component can better play an anti-counterfeiting role.

[0020] 3. The utility model provides an anti-counterfeiting safety structure for a fire extinguisher valve, which allows the anti-counterfeiting component to be connected to the pull ring and the lifting and pressing handle while adjusting the position. After use, the anti-counterfeiting component and the safety pin can always be connected to the lifting and pressing handle, thereby facilitating the recovery of the anti-counterfeiting component and the safety pin while recovering the fire extinguisher.

[0030] Example 1

[0031] This embodiment is the first embodiment of an anti-counterfeiting safety structure for a fire extinguisher valve. Figures 1 to 3 As shown, it includes a pressure handle 1 and a safety pin 2 for controlling the release of fire extinguishing agent, as shown in FIG. Figure 4 As shown, the safety bolt 2 includes an insertion pin 201 and a pull ring 202 connected in sequence, a through hole 111 for the insertion pin 201 to pass through is provided on the lifting and pressing handle 1, and an anti-counterfeiting component 3 is also included for preventing the insertion pin 201 from separating from the through hole 111. Figure 5 As shown, the anti-counterfeiting component 3 includes an anti-counterfeiting buckle 301 marked with anti-counterfeiting information, a cable tie 303, and a lock buckle 302 for locking the cable tie 303. The anti-counterfeiting buckle 301, the lock buckle 302, and the cable tie 303 are connected in sequence. The cable tie 303 passes through the pull ring 202, is wrapped around the outside of the lifting and pressing handle 1, and is connected to the lock buckle 302.

[0032] The working principle of the anti-counterfeiting safety structure of a fire extinguisher valve in this embodiment is as follows:

[0033] Before using the fire extinguisher, to prevent the valve from accidentally opening or being damaged, the insertion pin 201 of the safety bolt 2 is inserted into the through hole 111. This provides a protective function and reduces safety risks during storage and transportation of the fire extinguisher. A cable tie 303 is then passed through the pull ring 202 and wrapped around the outside of the lifting and pressing handle 1. After wrapping around the outside of the lifting and pressing handle 1, the cable tie 303 is tightened through the lock buckle 302, tightly connecting the anti-counterfeiting component 3 to the lifting and pressing handle 1 and the insertion pin 201. The anti-counterfeiting buckle 301 on the anti-counterfeiting component 3 is marked with anti-counterfeiting information, thereby ensuring that the safety bolt structure has good anti-counterfeiting performance. The prior art uses labels for anti-counterfeiting. However, because labels are generally soft, when the through hole 111 is large, the label is generally easy to slip out and easily re-insert, making it difficult to provide anti-counterfeiting protection. Unlike labels, the cable tie will inevitably be damaged when the fire extinguisher is used. Due to the damage of the anti-counterfeiting cable tie, the user can only return it to the original manufacturer for after-sales service, which helps to combat counterfeit and inferior products. At the same time, labels will lose their stickiness and become susceptible to damage over time due to changes in the environment and weather. Cable ties are also relatively durable and can adapt to more complex environments, such as outdoors or in situations where they are frequently touched. While cable ties are less susceptible to damage, labels may become scratched, faded, or fall off, rendering them ineffective. By providing anti-counterfeiting components 3, there is no need to machine small holes in the safety bolt 2, making the process less difficult. The simultaneous use of anti-counterfeiting buckles 301, cable ties 303, and lock buckles 302 for anti-counterfeiting allows for outdoor use and offers excellent durability.

[0034] Example 2

[0035] This embodiment proposes a fire extinguisher valve anti-counterfeiting safety structure. Based on the first embodiment, in this embodiment, Figure 3 As shown, the lifting and pressing handle 1 includes a rotating portion 101 and a pressing portion 102 connected in sequence. The through hole 111 is located in the rotating portion 101, and the cable tie 303 is wrapped around the outer side of the rotating portion 101 along the radial direction of the insertion pin 201. This can tightly bind the rotating portion 101 of the lifting and pressing handle 1, thereby preventing the lifting and pressing handle 1 from loosening during transportation.

[0036] The length of the insertion pin 201 is greater than the width L of the lifting handle 1. The lifting handle 1 is provided with a mounting base for connecting to the fire extinguisher. The mounting base 103 is connected to the rotating portion 101, and the cable tie 303 is located between the insertion pin 201 and the mounting base. The cable tie 303 is positioned to prevent it from being removed from other locations on the lifting handle 1, allowing the anti-counterfeiting component 3 to better perform its anti-counterfeiting function.

[0037] like Figure 3 and Figure 5 As shown, the anti-counterfeiting component 3 further includes an anti-slip strip 304, the two ends of which are respectively connected to the lock buckle 302 and the cable tie 303, and the anti-slip strip 304 abuts against the lifting and pressing handle 1. The friction between the anti-counterfeiting component 3 and the lifting and pressing handle 1 is enhanced to prevent the anti-counterfeiting component 3 from falling.

[0038] like Figure 2 and Figure 4 As shown, the pull ring 202 is configured as a completely closed structure, i.e., the pull ring 202 has no gaps, preventing the cable tie 303 from being removed from the gap in the pull ring 202, allowing the anti-counterfeiting component 3 to better play an anti-counterfeiting role. In this embodiment, the safety bolt 2 is preferably made of stainless steel, which serves the purpose of safety and rust prevention, can better adapt to different environmental conditions, and especially extends durability for outdoor use. The specific manufacturing method is to cut the stainless steel bar into a suitable length, straighten one end into a columnar shape, i.e., insert the pin 201, and bend the other end into a ring shape, i.e., the pull ring 202. The gap is filled with solder to prevent the cable tie 303 from being removed from the gap in the pull ring 202. The center of the pull ring 202 is preferably shaped to fit the finger, so that the user can quickly pull out the safety bolt 2 through the pull ring 202 during use.

[0039] The anti-counterfeiting component 3 is fixedly connected to the pull ring 202. The fixed connection can be achieved by welding or bonding. That is, the anti-counterfeiting component 3 is first passed through the pull ring 202 and wrapped around the lifting and pressing handle 1. After the cable tie 303 is passed through the lock buckle 302 and tightened and adjusted to the correct position, the anti-counterfeiting component 3 and the pull ring 202 are welded or bonded using an adhesive. When in use, the anti-counterfeiting component 3 needs to be destroyed, that is, the cable tie 303 is partially cut off to create space for the safety bolt 2 to be separated from the through hole 111. At the same time, after use, the anti-counterfeiting component 3 and the safety pin 2 can remain connected, so that the anti-counterfeiting component 3 can be recovered at the same time as the safety pin 2, and the material of the anti-counterfeiting component 3 can be recycled.

[0040] Example 3

[0041] This embodiment proposes a fire extinguisher valve anti-counterfeiting safety structure, based on the first or second embodiment, in this embodiment, as Figure 5As shown, the anti-counterfeiting component 3 is integrally molded. It is made of a plastic material that is waterproof, heat-resistant, cold-resistant, and corrosion-resistant, such as PP, PVC, or PE. This prevents the anti-counterfeiting buckle 301 from separating from the rest of the anti-counterfeiting component 3, allowing the anti-counterfeiting component 3 to better perform its anti-counterfeiting function. In this embodiment, the anti-counterfeiting mark is preferably engraved on the anti-counterfeiting buckle 301, meaning that the anti-counterfeiting mark can be simultaneously marked on the anti-counterfeiting buckle 301 during the integral injection molding process.

[0042] like Figure 6 As shown, the cable tie 303 includes a strap body 331 and a positioning buckle 332. The positioning buckle 332 is provided on the strap body 331 and is coaxial with the strap body 331. The strap body 331 is connected to the lock buckle 302. The lock buckle 302 has a through hole 321 therein. The lock buckle 302 has multiple elastic pieces 322 facing the center of the through hole 321 and connected to the inner wall of the through hole 321. The positioning buckle 332 abuts against the elastic pieces 322. The strap body 331 passes through the through hole 321 and is wrapped around the lifting and pressing handle 1. The cable tie 303 is then securely connected to the lock buckle 302 via the positioning buckle 332 and the elastic pieces 322. In this embodiment, the cable tie 303 is a fishbone-shaped cable tie, which is more convenient to operate than a square-shaped cable tie. Fishbone cable ties require only threading through the pin hole to tighten, making them quick and convenient, saving time and labor. Square-shaped cable ties, however, are wider and less compatible with latches, requiring greater force to tighten, increasing the difficulty and complexity of the operation. The fishbone teeth of fishbone cable ties provide excellent anti-slip and anti-loosening properties after tightening, firmly securing the handle and providing a tight fit and more stable retention. Square-shaped cable ties have a simpler design, but they cannot fit tightly with irregularly shaped latches, making them prone to loosening due to vibration or uneven force during transportation.

[0043] Multiple positioning buckles 332 are provided axially along the strap 331. After the strap 331 is passed through the through-hole 321, the number of positioning buckles 332 passed through the through-hole 321 can be freely selected, thereby flexibly adjusting the size of the binding loop formed by the cable tie 303 and the tightness of the binding and lifting handle 1. The outer diameter of the positioning buckles 332 gradually decreases from the buckle 302 to the strap 331. Specifically, the end of the positioning buckle 332 farther from the buckle 302 is smaller than the end of the positioning buckle 332 closer to the buckle 302. This facilitates smooth insertion of the positioning buckles 332 through the through-hole 321 when tightening the cable tie 303, while also making reverse movement of the strap 331 more difficult.

[0044] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
