Description

Technical Field

[0001] This utility model belongs to the field of electronic fuse technology, specifically relating to an anti-interference protection device for electronic fuses. Background Technology

[0002] A fuse, also known as a detonator, is a detonating device attached to artillery shells, bombs, landmines, etc. A fuse is a control device that uses target and environmental information to detonate or ignite the propellant charge of an ammunition under predetermined conditions. Different fuses are selected according to different types of artillery shells and the needs of engaging targets; the fuse of a firecracker was the earliest form of fuse.

[0003] There are two types of fuses: one is a mechanical fuse, which uses an external force to strike the primer and then ignites the main charge; the other is an electronic fuse, which is triggered by electric heating. Protecting electronic fuses during transportation or use is particularly important to effectively prevent damage.

[0004] When using existing electronic fuses, various interference signals such as shock waves generated during on-site blasting and detonation may damage the internal electronic control module, causing the electronic detonator to mis-detonate or detonate, thus resulting in serious safety accidents. Furthermore, electronic fuses are inevitably subject to bumps and knocks during transportation and use. Due to the large number and complexity of internal components, electronic fuses are highly susceptible to damage from external impacts.

[0005] A patent document with patent publication number CN 221037123U was found, which discloses an anti-interference protection structure for an electronic fuse, including an electronic fuse body. The outer surface of the electronic fuse body is movably fitted with a protective shell one and a protective shell two. Multiple fixing plates are respectively fixedly installed on the outer surface of the protective shell one and the protective shell two near the upper end, and the multiple fixing plates are evenly divided into two groups. Multiple buffer springs are respectively fixedly installed on the opposite sides inside the protective shell one and the protective shell two, and the other end of each of the multiple buffer springs is fixedly installed with an arc-shaped buffer plate.

[0006] However, the following problems still exist in the use of this electronic fuse anti-interference protection structure:

[0007] The protective shell 1 and the protective shell 2 are two separate shells. Placing the electronic fuse inside the protective shell 1 and the protective shell 2 causes inconvenience in operation. In addition, the two protective shells need to be aligned and fixed with multiple bolts and nuts. This operation is cumbersome and has too many small parts, which increases the difficulty of storage.

[0008] (2) Furthermore, no buffer structure is provided at the bottom of the electronic fuse, so it cannot be properly cushioned and protected during use and transportation.

[0009] Therefore, there is an urgent need to design an anti-interference protection device for electronic fuses to solve the above problems. Utility Model Content

[0010] To address the problems of cumbersome operation, numerous small parts leading to complex procedures and increased storage difficulties in the existing technology, as well as the lack of a buffer protection structure for the bottom of the electronic fuse, the purpose of this utility model is to provide an anti-interference protection device for an electronic fuse, including a first shell and a second shell that are hinged to each other, and an anti-interference buffer layer and a buffer base are provided in the cavity formed by the first shell and the second shell to provide buffer protection and anti-interference protection for the electronic fuse, preventing it from being damaged, and at the same time enabling quick installation of the protection device and the electronic fuse.

The protective shell comprises a shell 1 and a shell 2 that are hinged to each other, and an anti-interference buffer layer is provided in the cavity formed by the shell 1 and the shell 2, and a buffer base adapted to the electronic fuse is provided at the bottom of the cavity.

[0014] Preferably, the anti-interference buffer layer includes an anti-interference buffer shell one and an anti-interference buffer shell two that are adapted to each other, and the anti-interference buffer shell one is adapted to the shell one, and the anti-interference buffer shell two is adapted to the shell two.

[0015] Preferably, buffer components are also provided on the inner walls of the first and second anti-interference buffer shells.

[0016] Preferably, the buffer component is wavy and hollow, with air filling inside.

[0017] Preferably, the buffer component has a corrugated solid structure and is made of rubber or silicone.

[0018] Preferably, the buffer base includes rubber plates and fixing plates spaced apart from each other, and an embedding groove is provided at the upper end of the buffer base.

[0019] Preferably, it further includes a fastening assembly disposed on the upper half of the protective shell.

[0020] Preferably, the fastening assembly includes a first clamping body and a second clamping body that are hinged to each other, and the first clamping body and the second clamping body are connected by bolts, with nuts screwed onto the bolts.

[0021] The beneficial effects of this utility model are as follows: This utility model discloses an electronic fuse anti-interference protection device. Compared with the prior art, the improvement of this utility model lies in:

[0024] (3) The present invention makes it more convenient and efficient to install a protective device on an electronic fuse by means of hinged housing 1 and housing 2. The range of selection of the combined fixing parts of housing 1 and housing 2 is wide. According to the fixing requirements, the binding strap or elastic fixing strap can be directly selected, so that the protective device can be used in various situations. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] Example:

[0034] See attached document Figure 1-6 An anti-interference protection device for an electronic fuse is shown, including a protective shell 2 sleeved on an electronic fuse 1. The protective shell 2 includes a shell 1 201 and a shell 2 202 that are hinged to each other. An anti-interference buffer layer 3 is provided in the cavity formed by the shell 1 201 and the shell 2 202. The anti-interference buffer layer 3 is fixedly provided on the inner wall of the shell 1 201 and the shell 2 202 and forms an integral part with the shell 1 201 and the shell 2 202. A buffer base 5 adapted to the protective shell 2 is fixedly provided at the bottom of the cavity formed by the shell 1 201 and the shell 2 202. When the electronic fuse 1 is placed in the protective shell 2, it can be stably placed in the buffer base 5.

[0035] Among them, the first shell 201 and the second shell 202 are hinged together. When not in use, they are a whole. When in use, the first shell 201 and the second shell 202 can be pried apart, the electronic fuse 1 can be placed into its inner cavity, and then the first shell 201 and the second shell 202 can be merged and fixed together, so as to achieve the purpose of quick installation of the protective shell 2 and the electronic fuse 1.

[0036] For details, please refer to the attached document. Figure 2-4 As shown, the anti-interference buffer layer 3 includes an anti-interference buffer shell 301 and an anti-interference buffer shell 302 that are adapted to each other. The anti-interference buffer shell 301 is adapted to the shell 201, and the anti-interference buffer shell 302 is adapted to the shell 202. That is, the anti-interference buffer shell 301 and the anti-interference buffer shell 302 are respectively fixedly installed on the inner walls of the shell 201 and the shell 202. When the shell 201 and the shell 202 are closed, the anti-interference buffer shell 301 and the anti-interference buffer shell 302 are also closed to form a sealed ring.

[0037] Furthermore, the inner walls of the anti-interference buffer shell 1 301 and the anti-interference buffer shell 2 302 are also provided with buffer components 303 to buffer and protect the electronic fuse 1. The buffer components 303 are in contact with the outer wall of the electronic fuse 1 to provide shockproof buffer protection for the electronic fuse 1 and prevent it from being directly subjected to pressure from the side.

[0038] The buffer component 303 is corrugated and hollow, filled with air, and has an inflation port with a one-way valve to prevent air leakage. When the electronic fuse 1 is subjected to external pressure, the buffer component 303 provides shock absorption and cushioning protection. The corrugated design increases the contact area with the electronic fuse 1, further enhancing its fixing effect. The buffer component 303 can also be made of solid rubber or silicone, which can also provide shock absorption and cushioning without the need for inflation.

[0039] Further references Figure 2 and Figure 5 As shown, the buffer base 5 includes a rubber plate 501 and a fixing plate 502 that are spaced apart from each other, and an embedding groove 503 is provided at the upper end of the buffer base 5. The embedding groove 503 is adapted to the electronic fuse 1 and is used to place the electronic fuse 1.

[0040] In order to facilitate the merging and fixing of housing 1 201 and housing 2 202, a fastening component 4 is also provided to fix housing 1 201 and housing 2 202 in the upper part, so that housing 1 201 and housing 2 202 become a whole and tightly fix the electronic fuse 1.

[0041] For details, please refer to the attached document. Figure 6 As shown, the fastening assembly 4 is located in the upper half of the protective shell 2, including a first clamping body 401 and a second clamping body 402 that are hinged to each other. The first clamping body 401 and the second clamping body 402 are connected by a bolt 403, and a nut 404 is screwed onto the bolt 403. The bolt 403 passes through the first clamping body 401 and the second clamping body 402 and cooperates with the nut 404, so that the first clamping body 401 and the second clamping body 402 are tightly closed together.

[0042] The principle and process of the electronic fuse anti-interference protection device in this embodiment are as follows: First, the housing 1 201 and housing 2 202 are separated. Then, the electronic fuse 1 is placed into the embedding groove 503. Next, the housing 1 201 and housing 2 202 are merged together. The housing 1 201 and housing 2 202 are fixed by using the clamping body 1 401, the clamping body 2 402, the bolt 403, and the nut 404. Then, air is injected into the buffer component 303.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
