Description

Technical Field

[0001] This utility model belongs to the field of explosion-proof blanket technology, specifically, it relates to an explosion-proof blanket with a quick fixing function. Background Technology

[0002] Explosion-proof blankets are made of high-strength bulletproof fiber material, characterized by their wear resistance and water resistance. They effectively protect against shock waves and fragments from explosives, preventing or mitigating damage to surrounding personnel, valuable instruments, cultural relics, and special public places. Primarily used for the temporary isolation, storage, and disposal of explosive materials, they are essential equipment for explosion-proof security inspection departments such as public security, armed police, civil aviation, railways, ports, customs, and sports venues. The products are lightweight, portable, easy to operate, and highly blast-resistant.

[0003] Currently, before covering explosives with an explosion-proof blanket, it is necessary to use inner and outer fences to surround the explosives, and then cover them with the explosion-proof blanket. However, the explosion-proof blanket cannot be quickly fixed around its perimeter, which can cause it to shift during an explosion, resulting in explosive fragments flying everywhere and causing harm. Therefore, we have proposed an explosion-proof blanket with a quick-fixing function, and this utility model is hereby proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an explosion-proof blanket with a quick fixing function.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] An explosion-proof blanket with a quick-fixing function includes a blanket body, a pin head, and a fixing base. Each of the four corners of the blanket body is fixed with a connecting strap. Each end of the connecting strap is fitted with a positioning head by a fixing bolt. A reserved hole for fixing the pin head is opened through the middle of the positioning head. The pin head is movably connected to a movable cavity opened on one side of the fixing base. A return spring abuts between the pin head and the movable cavity. A lever is fixed to the side of the pin head. The lever is connected through the side of the movable cavity.

[0007] One side of the fixed base has a groove for inserting a positioning head, and a limiting hole for a pin to pass through is provided at the bottom of the groove. The other side of the fixed base has a mounting cavity for mounting a motor and two fixing rods. The output shaft of the motor is fixed to a reciprocating screw through a coupling. A threaded sleeve is installed on the outside of the reciprocating screw. Support plates are fixed on both sides of the threaded sleeve. The lower ends of the two support plates are fixed to the two fixing rods respectively. The bottom of the mounting cavity for mounting the fixing rods has a clearance hole. A guide block adapted to the guide rail is fixed on the side of the support plate. The guide rail is fixed inside the movable cavity.

[0008] Optionally, both the upper and lower ends of the blanket are provided with first Velcro for attaching the auxiliary reinforcement blanket, and the surface of the auxiliary reinforcement blanket at the upper end is coated with a fluorescent liquid outline coating.

[0009] Optionally, each of the fixed rods has grooves on both sides for mounting the fixed sleeve, and each fixed sleeve has an extension sleeve movably connected to its side end. A telescopic airbag is provided between the extension sleeve and the fixed sleeve, and each telescopic airbag is connected to the air injection chamber inside the fixed rod through a conduit.

[0010] Optionally, the two ends of the telescopic airbag are mounted to the opposite sides of the fixed sleeve and the extension sleeve via a second Velcro fastener.

[0011] Optionally, the top of each of the two support plates is equipped with a telescopic pipe connected to an air supply nozzle. The lower end of the air nozzle is connected to the air injection chamber inside the fixed rod. The telescopic pipe passes through the equipment cavity inside the fixed seat and is connected to the two air injection ends of the multi-port pipe.

[0012] Optionally, a small air pump is fixed inside the equipment cavity. The air supply end of the small air pump is connected to the air supply end of the multi-port pipe, and the exhaust end of the multi-port pipe is connected to the exhaust pipe through a control valve. The top of the exhaust pipe extends through to the upper end of the fixed base.

[0013] Optionally, the negative pressure end of the small air pump is connected to a negative pressure pipe, an air filter is provided inside the negative pressure pipe, and an air inlet is provided at the top of the equipment cavity for installing the filter.

[0014] Optionally, the fixing base is provided with L-shaped parts on both sides, and a screw hole for screwing in the middle of the L-shaped parts is provided.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0016] 1. This utility model uses the pin head of the fixing seat, the connecting straps at the four corners of the blanket body, and the positioning head to quickly fix the blanket body, thereby improving the safety during explosion-proof treatment. Specifically, the four fixing seats are fixed to the four corners of the explosion-proof fence or explosion-proof cylinder in advance. Then, the motor switch is turned on, and the output shaft of the motor drives the reciprocating screw to rotate. The reciprocating screw, through the threaded sleeve, cooperates with the guide block and the guide rail to make the support plate move longitudinally. During the longitudinal movement of the support plate, the driving fixing rod is inserted into the ground where the explosion-proof barrel or explosion-proof fence is placed. Then, when covering the explosion-proof blanket, the blanket body is directly inserted into the groove through the positioning head at the end of the connecting strap. Then, the lever is released. At this time, the return spring drives the pin head to descend and penetrate the middle of the positioning head to complete the limiting process. The four fixing seats fixed to the ground and the positioning heads at the four corners of the blanket body are connected to fix the blanket body covering the explosion-proof barrel or explosion-proof fence.

[0017] 2. This utility model takes into account that the fixing effect is not good when the ground soil is relatively loose after the fixing rod is inserted into the ground. After the fixing rod is inserted into the ground, the switch of the micro air pump will be turned on. The micro air pump injects gas into the air injection nozzle and into the air injection chamber, thereby causing the internal telescopic airbags of multiple fixing sleeves to expand. During the expansion of the telescopic airbags, the extension sleeves on the side of the fixing sleeves will be pushed out and embedded into the surrounding soil, thereby further enhancing the fixing effect of the fixing rod.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Please see Figures 1 to 6 This utility model provides a technical solution: an explosion-proof blanket with a quick fixing function, including a blanket body 1, a pin head 5 and a fixing seat. Each of the four corners of the blanket body 1 is fixed with a connecting strap 2. Each end of the connecting strap 2 is equipped with a positioning head 4 through a fixing bolt 3. The center of the positioning head 4 is provided with a reserved hole for fixing the pin head 5. The pin head 5 is movably connected to a movable cavity opened on one side of the fixing seat. A return spring 6 abuts between the pin head 5 and the movable cavity. A lever 7 is fixed to the side of the pin head 5. The lever 7 is connected through the side of the movable cavity.

[0031] One side of the fixed base has a groove for inserting the positioning head 4, and a limiting hole for the pin head 5 to pass through at the bottom of the groove. The other side of the fixed base has mounting cavities for the motor 8 and two fixing rods 9. The output shaft of the motor 8 is fixed to the reciprocating screw 11 via a coupling. A threaded sleeve 12 is installed on the outside of the reciprocating screw 11, and support plates 13 are fixed on both sides of the threaded sleeve 12. The lower ends of the two support plates 13 are fixed to the two fixing rods 9 respectively. A clearance hole 14 is provided at the bottom of the mounting cavity for installing the fixing rods 9. A guide block 16 adapted to the guide rail 15 is fixed to the side of the support plate 13. The guide rail 15 is fixed inside the movable cavity. Considering that the explosion-proof blanket cannot be quickly fixed around its perimeter, it is easy for the blanket to shift during an explosion, causing explosive fragments to fly and cause harm. This utility model addresses this by using the pin head 5 of the fixed base to connect with the four corners of the blanket body 1... The connecting strap 2 and the positioning head 4 work together to quickly fix the blanket 1, thereby improving the safety during explosion-proof treatment. Specifically, the four fixing seats are fixed to the four corners of the explosion-proof fence or explosion-proof cylinder in advance. Then, the switch of the motor 8 is turned on. The output shaft of the motor 8 drives the reciprocating screw 11 to rotate. The reciprocating screw 11, through the threaded sleeve 12, cooperates with the guide block 16 and the guide rail 15 to make the support plate 13 move longitudinally. During the longitudinal movement of the support plate 13, the drive fixing rod 9 is inserted into the ground where the explosion-proof barrel or explosion-proof fence is placed. Then, when covering the explosion-proof blanket, the blanket 1 is directly inserted into the groove through the positioning head 4 at the end of the connecting strap 2. Then, the lever 7 is released. At this time, the return spring 6 drives the pin head 5 to descend and penetrate the middle of the positioning head 4 to complete the limiting process. The four fixing seats fixed to the ground are connected with the positioning heads 4 at the four corners of the blanket 1 to fix the blanket 1 covering the explosion-proof barrel or explosion-proof fence.

[0032] The blanket body 1 has a first Velcro 18 at both the upper and lower ends for attaching the auxiliary reinforcement blanket 17. The surface of the auxiliary reinforcement blanket 17 at the upper end is coated with a fluorescent liquid outline coating 19. The first Velcro 18 serves to install the auxiliary reinforcement blanket 17 and the blanket body 1. The presence of the auxiliary reinforcement blanket 17 improves the strength of the blanket body 1.

[0033] Each of the fixing rods 9 has grooves on both sides for mounting the fixing sleeves 20. Each fixing sleeve 20 has an extension sleeve 21 movably connected to its side end. A telescopic airbag 22 is provided between the extension sleeve 21 and the fixing sleeve 20. Each telescopic airbag 22 is connected to the air injection chamber 24 inside the fixing rod 9 through a conduit 23. Considering that the fixing effect is not good when the ground soil is relatively loose after the fixing rod 9 is inserted into the ground, the micro air pump will be activated after the fixing rod 9 is inserted into the ground. The micro air pump injects gas into the air injection nozzle 26 into the air injection chamber 24, thereby causing the telescopic airbags 22 inside the multiple fixing sleeves 20 to expand. During the expansion of the telescopic airbags 22, the extension sleeves 21 on the side end of the fixing sleeve 20 will be pushed out and embedded into the surrounding soil, thereby further enhancing the fixing effect of the fixing rod 9.

[0034] The two ends of the telescopic airbag 22 are mounted to the opposite sides of the fixed sleeve 20 and the extension sleeve 21 via the second Velcro fastener 25. The second Velcro fastener serves to install the telescopic airbag 22 to the fixed sleeve 20 and the extension sleeve 21.

[0035] The top of each of the two support plates 13 is equipped with a telescopic pipe 27 connected to an air nozzle 26. The lower end of the air nozzle 26 is connected to the air injection chamber 24 inside the fixed rod 9. The telescopic pipe 27 passes through the equipment cavity inside the fixed seat and is connected to the two air injection ends of the multi-port pipe 28. The telescopic pipe 27 is used to inject air into the air nozzle 26.

[0036] The device cavity contains a small air pump 29, whose air supply end is connected to the air supply end of a multi-port pipe 28. The exhaust end of the multi-port pipe 28 is connected to an exhaust pipe 31 via a control valve 30. The top of the exhaust pipe 31 extends to the upper end of the fixed base. The control valve 30 is used to discharge the gas inside the telescopic airbag 22. When the control valve 30 is opened, the gas inside the telescopic airbag 22 will be discharged through the exhaust pipe 31. After the gas in the telescopic airbag 22 is discharged, it contracts. At this time, the extension tube retracts into the interior of the fixed sleeve 20, which facilitates the retraction of the fixed rod 9.

[0037] The negative pressure end of the small air pump 29 is connected to a negative pressure pipe 32. An air filter element 33 is provided inside the negative pressure pipe 32. An air inlet is provided at the top of the equipment cavity for installing a filter screen 34. By setting the filter screen 34 in conjunction with the air filter element 33, the air drawn in by the small air pump 29 under negative pressure is filtered, avoiding dust or particles in the air from clogging the pipe.

[0038] The fixing base is provided with L-shaped parts 10 on both sides. A screw hole for screwing in bolts is opened in the middle of the L-shaped parts 10. By setting the L-shaped parts 10, the fixing base for long-term use can be fixed with screws. For short-term use, it can be fixed directly with the fixing rod 9.

[0039] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
