Description

Technical Field

[0001] This invention relates to the field of emergency rescue equipment technology, and in particular to a quick-assembly and disassembly electric cutting knife. Background Technology

[0002] Rescue and disaster relief equipment and counter-terrorism and emergency response equipment are two relatively new categories of firefighting equipment. They have gradually developed and formed with the expansion of the functions of public security and fire brigades, and mainly include detection, warning, breaching, and lighting equipment. Among them, breaching equipment has undergone a period of development, resulting in a number of innovative and reliable products. These are used in situations such as fires, earthquakes, car accidents, and emergency rescues to quickly breach and remove obstacles such as security window bars, collapsed building steel bars, and window railings.

[0003] The existing handheld chemical energy-based non-electric cutting knife, invented through research and development, can perform not only point-like demolition but also linear and multi-point demolition. It can break through not only metal obstacles but also tempered glass, insulated tempered glass, and other glass objects. However, the non-electric cutting knife consists of a cartridge and an ignition handle. Because the ignition switch on the ignition handle is easily accidentally activated, the cartridge and ignition handle are usually stored separately before use. They are only temporarily assembled before use and then disassembled as soon as possible after the work is completed to prevent accidental activation and potential accidents. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by proposing a quick-assembly and disassembly-free electric cutting knife.

[0005] A quick-assembly and disassembly electric cutting knife includes a cartridge and an activation handle. The activation handle includes a handle housing and a handle body. The handle housing includes an upper housing and a lower housing. The handle body is installed in the handle housing. The cartridge includes an integrally formed cartridge base and a cartridge body. The cartridge base contacts and engages with the handle body in the handle housing. The cartridge body extends out of the handle housing. A locking mechanism for fixing the upper housing and the lower housing is provided at the end of the handle housing away from the cartridge.

[0006] Furthermore, the locking mechanism includes a connecting block, a fixed block, a connecting plate, a movable block, a first spring, a movable plate, a mating block, a limiting plate, and a second spring. The side of the fixed block is fixedly connected to the lower housing, and a fixed hole is provided on the top surface of the fixed block. The connecting plate mates with the fixed hole, and the top surface of the connecting plate is connected to the bottom surface of the connecting block. The side of the connecting block is connected to the upper housing. A movable groove is provided on the wall of the fixed hole, and the movable block is disposed in the movable groove. The side of the movable block is fixedly connected to the connecting plate, and the bottom surface of the movable block is connected to the closed end of the movable groove through a spring. A limiting hole communicating with the fixed hole is provided on the side of the fixed block, and one end of the movable plate is inserted into the limiting hole. A limiting groove is provided on the wall of the limiting hole, and the mating block is installed in the limiting groove. The top surface of the mating block is connected to the movable plate. A mating hole is provided at the bottom of the side of the connecting plate, and the axis of the mating hole is coaxial with the axis of the limiting hole. One end of the limiting plate is inserted into the limiting hole, and the other end is inserted into the mating hole and connected to the bottom of the mating hole through a second spring.

[0007] Furthermore, both the first spring and the second spring are cylindrical helical compression springs.

[0008] Furthermore, the upper housing is provided with a press hole that mates with the ignition switch on the handle body.

[0009] Furthermore, a ball bearing is provided on the side of the limiting plate away from the second spring.

[0010] The beneficial effects of this invention are as follows: With the locking mechanism, the upper and lower housings can be separated or joined very quickly and conveniently. This makes it easy to disassemble and assemble the cartridge of the electric cutting knife without spending a lot of time and affecting work efficiency. Moreover, the electric cutting knife can be quickly disassembled and the cartridge can be removed when not in use, thereby reducing the risk of the electric cutting knife being accidentally touched.

[0015] Example 1

[0016] like Figure 1-2 As shown, the present invention provides a quick-assembly and disassembly electric cutting knife, including a cartridge and an activation handle. The activation handle includes a handle housing and a handle body 1. The handle housing includes an upper housing 2 and a lower housing 3. The handle body 1 is installed in the handle housing. The cartridge includes an integrally formed cartridge base 4 and a cartridge body 5. The cartridge base 4 contacts and engages with the handle body 1 in the handle housing. The cartridge body 5 extends out of the handle housing. A locking mechanism for fixing the upper housing 2 and the lower housing 3 is provided at the end of the handle housing away from the cartridge.

[0017] In this embodiment, the locking mechanism includes a connecting block 6, a fixing block 7, a connecting plate 8, a movable block 9, a first spring 10, a movable plate 11, a mating block 12, a limiting plate 13, and a second spring 14. The side of the fixing block 7 is fixedly connected to the lower housing 3, and a fixing hole 15 is provided on the top surface of the fixing block 7. The connecting plate 8 mates with the fixing hole 15, and the top surface of the connecting plate 8 is connected to the bottom surface of the connecting block 6. The side of the connecting block 6 is connected to the upper housing 2. A movable groove 16 is provided on the wall of the fixing hole 15, and the movable block 9 is disposed in the movable groove 16. The side of the movable block 9 is fixedly connected to the connecting plate 8, and the bottom surface of the movable block 9 is fixedly connected to the connecting plate 8. The first spring 10 is connected to the closed end of the movable groove 16. A limiting hole 17 communicating with the fixed hole 15 is provided on the side of the fixed block 15.
