Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides an explosion-proof positioning chest card, which protects the positioning card part in the center of the card by elastically enclosing a protective card part connected to the positioning card part, and elastically separates and releases the force when subjected to an external force of an explosion, thereby greatly reducing the probability of the positioning card part and internal electronic components being damaged.

[0005] Furthermore, under the impact of external force, the protection card part is converted from an elastically clamped connected state relative to the positioning card part to an elastically slid-out separated state, and each of the protection card parts is elastically separated from the positioning card part by an elastic clamping piece.

[0006] Furthermore, the elastic snap-in component includes a snap joint connected to the protective snap part, a snap slot connected to the positioning snap part, and an elastic pad fitted in the snap slot; the snap joint is inserted into the snap slot to achieve snap fit by relying on the elastic clamping force provided by the elastic pad.

[0007] Furthermore, a filling portion is connected to the gap between adjacent protection clamping portions, and a broken groove is formed on the filling portion along a midline position parallel to the edge of the protection clamping portion.

[0008] Furthermore, the outer ends of some adjacent protection clamping parts are connected with sealing rods, and the limiting position between the sealing rods and the protection clamping parts forms a hanging opening for connecting a wearing rope.

[0009] Furthermore, the card connector, the card slot, the outer shell of the positioning card part and the outer shell of the protective card part are all structures made of explosion-proof materials.

[0010] Furthermore, the positioning card portion and the protection card portion both have regular hexagonal shapes.

[0011] Beneficial effects: In the utility model, the positioning card part is an important component of the chest badge, which is equipped with electronic components such as communication modules, batteries, chips and sensors. The protective card part that is elastically connected to the positioning card part is elastically separated and releases force when subjected to external force of explosion, thereby protecting the positioning card part in the center of the card, greatly reducing the probability of damage to the positioning card part and internal electronic components, making it easy to quickly find the chest badge through positioning, and providing convenience for accident rescue and investigation.

[0016] The utility model is further described below in conjunction with the accompanying drawings.

[0017] As attached Figure 1 and attached Figure 2 As shown, an explosion-proof positioning chest card includes a positioning card part 1 and a protection card part 2, wherein an elastic clamping part 3 is provided between the positioning card part 1 and the protection card part 2, wherein the protection card part 2 includes an elastic clamping connection state relative to the positioning card part 1 and an elastic sliding separation state through the elastic clamping part 3, and in the elastic clamping connection state, a plurality of the positioning card parts 1 surround the positioning card part 1 at the center of the card. When subjected to external force impact, the protection card part 2 is converted from the elastic clamping connection state relative to the positioning card part 1 to the elastic sliding separation state, and each of the protection card parts 2 is elastically separated from the positioning card part 1 through the elastic clamping part 3. In the utility model, the positioning card part 1 is an important component of the chest badge, which is equipped with electronic components such as communication modules, batteries, chips and sensors. The protective card part 2 connected to the positioning card part 1 through elastic enclosure is elastically separated to release force when subjected to external force of explosion, thereby protecting the positioning card part 1 in the center of the card, greatly reducing the probability of damage to the positioning card part 1 and internal electronic components, making it easy to quickly find the chest badge through positioning, and providing convenience for accident rescue and investigation.

[0018] As attached Figure 3As shown, the elastic clamping member 3 includes a clamping joint 31 connected to the protective clamping part 2, a clamping slot 32 connected to the positioning clamping part 1, and an elastic pad 33 fitted in the clamping slot 32; the clamping joint 31 is inserted into the clamping slot 32 to achieve clamping fit by relying on the elastic clamping force provided by the elastic pad 33. In the event of an explosion, the elastic force provided by the elastic pad 33 of the elastic clamping member 3 is also relied on for force release protection. When the protective clamping part 2 is separated from the positioning clamping part 1, the protective clamping part 2 also plays a role in force release protection.

[0019] As attached Figure 4 As shown, a filling portion 4 is connected to the gap between adjacent protection card portions 2, and a broken groove 40 is provided along the midline position of the filling portion 4 parallel to the edge of the protection card portion 2. When an explosion accident occurs, the presence of the broken groove 40 can easily cause the filling portion 4 to break, thereby separating adjacent protection card portions 2, which is more conducive to the separation of the protection card portion 2 and the positioning card portion 1.

[0020] As attached Figure 1 As shown, the outer ends of some adjacent protection card parts 2 are connected with sealing rods 5, and the sealing rods 5 and the protection card parts 2 are limited to form a hanging hole 7 for connecting the wearing rope 6. In the utility model, the filling part 4 and the sealing rod 5 are made of fragile materials, such as plastic, which is more likely to break in the event of an explosion. The card joint 31, the card slot 32, the outer shell of the positioning card part 1 and the outer shell of the protection card part 2 are all structures made of explosion-proof materials.

[0021] In the present utility model, preferably, the positioning card portion 1 and the protection card portion 2 are both regular hexagonal in shape.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
