Description

Technical Field

[0001] The utility model belongs to the technical field of self-rescuers, in particular to an upper shell quick-disassembly structure of a heat dissipation type self-rescuer. Background Art

[0002] The heat dissipation type self-rescuer is a portable respiratory protection device that can be carried by personnel entering the mine to prevent poisoning by harmful gases or suffocation due to lack of oxygen when a fire, gas, coal dust explosion, or coal and gas outburst occurs underground. The self-rescuer is a small, light and easy-to-carry equipment for protecting personal respiratory organs.

[0003] The upper and lower shells of traditional self-rescuers are generally designed with plastic materials, and the joints are connected by snapping. However, in complex environments, especially at low temperatures, the plastic snap-fitting material will shrink due to cold shrinkage, causing the joints to tighten, which will cause jamming when the upper shell needs to be removed. In severe cases, the upper shell cannot be pulled out. To this end, we propose a quick-release structure for the upper shell of a self-rescuer to address the above-mentioned deficiencies. Utility Model Content

[0004] The utility model aims to provide an upper shell quick-disassembly structure of a heat dissipation type self-rescuer, which can quickly pull out the upper shell so as to use it quickly, so as to solve the above-mentioned background technical problems.

[0005] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a quick-release structure of an upper shell of a heat-dissipating self-rescuer, which is arranged between a lower shell and an upper shell, and includes a support plate fixedly connected to the top of both sides of the lower shell, and the left and right sides of the top of each support plate are fixedly connected to a connecting seat, and the connecting seat is fixedly connected to a connecting rod at a relative position, and the surface of the connecting rod is respectively slidably sleeved with a clamping plate 1 and a clamping plate 2, and the upper position of the outer side of the clamping plate 1 and the clamping plate 2 is fixedly connected with a protrusion, and the bottom of the protrusion is fixedly connected with a spring, and the bottom of the spring is fixedly connected to the top of the support plate, and the lower position of both sides of the upper shell are fixedly connected with a clamping head, and the outer surface of the clamping head slides in accordance with the inner arc surface formed by the clamping plate 1 and the clamping plate 2, and when the clamping head slides between the clamping plate 1 and the clamping plate 2, it is elastically clamped by the spring.

[0006] Preferably, the midpoints of the four sides of the bottom of the upper shell are fixedly connected with limiting columns, and the top end surface of the lower shell is provided with limiting holes adapted to be plugged with the limiting columns.

[0007] Preferably, a rubber pad is bonded to the end surface of the top of the lower shell, and a through hole corresponding to the limiting hole is provided inside the rubber pad.

[0008] Preferably, the first clamping plate is fixedly connected to a first ring on an end face close to the connecting rod, and the inner surface of the first ring is slidably connected to the outer surface of the connecting rod; the second clamping plate is fixedly connected to a second ring on an end face close to the connecting rod, and the inner surface of the second ring is slidably connected to the outer surface of the connecting rod; the second ring is located on the outside of the first ring, and the first ring and the second ring are staggered with each other.

[0009] Preferably, a through slot for deflection of the first and second clamping plates is provided on the top of the support plate.

[0010] 1. The beneficial effect of the utility model is that when the lower shell and the upper shell are connected, the clamping head is clamped in the arc-shaped clamping groove formed by the clamping plate 1 and the clamping plate 2, and the convex block is driven to shift its position through the action force of the spring, so that the clamping plate 1 and the clamping plate 2 are mutually clamped on the outer surface of the clamping head.

By setting the above structure, the purpose of quickly pulling out the upper shell is achieved, so that it can be used quickly.

The structure is arranged between the lower shell 1 and the upper shell 2. The structure includes a support plate 3 fixedly connected to the top of both sides of the lower shell 1, and the left and right sides of the top of each support plate 3 are fixedly connected to a connecting seat 4, and a connecting rod 5 is fixedly connected to the relative position of the connecting seat 4. The surfaces of the connecting rod 5 are slidably sleeved with a clamping plate 1 6 and a clamping plate 2 7 respectively, and the upper positions of the outer sides of the clamping plate 1 6 and the clamping plate 2 7 are fixedly connected with a protrusion 13, and the bottom of the protrusion 13 is fixedly connected with a spring 8, and the bottom of the spring 8 is fixedly connected to the top of the support plate 3. The lower positions of both sides of the upper shell 2 are fixedly connected with a clamping head 9, and the outer surface of the clamping head 9 is adapted to slide with the inner arc surface formed by the clamping plate 1 6 and the clamping plate 2 7. When the clamping head 9 slides between the clamping plate 1 6 and the clamping plate 2 7, it is elastically engaged by the spring 8. The end face of the clamping plate 1 6 close to the connecting rod 5 is fixedly connected with a ring 1, and the inner surface of the ring 1 is slidably connected to the outer surface of the connecting rod 5. A second collar is fixedly connected to one end face close to the connecting rod 5, and the inner surface of the second collar is slidably connected to the outer surface of the connecting rod 5. The second collar is located on the outer side of the first collar, and the first collar and the second collar are staggered with each other. A through groove for the deflection of the first card plate 6 and the second card plate 7 is provided on the top of the support plate 3. By arranging the first collar and the second collar connected to the first card plate 6 and the second card plate 7 respectively, the first card plate 6 and the second card plate 7 can be rotated at a certain angle with the connecting rod 5 as the axis. When the upper shell 2 needs to be pulled out, It is only necessary to pull out the upper shell body 2 to drive the clamping head 9 to move upward, and the clamping head 9 slides on the inner arc surface formed by the clamping plate 1 6 and the clamping plate 2 7. When the clamping head 9 moves upward, it will lift the clamping plates 1 6 and the clamping plates 2 7 on both sides, so that the clamping plates 1 6 and the clamping plates 2 7 slide and rotate on the outer surface of the connecting rod 5, and compress the spring 8 through the protrusion 13, and then pull the clamping head 9 out completely. By setting the above structure, the purpose of quickly pulling out the upper shell is achieved, so that it can be used quickly.

[0023] Embodiment 2:

[0024] Figure 1-3The upper shell quick-release structure of a heat dissipation type self-rescuer of an embodiment of the utility model is shown, which is arranged between the lower shell 1 and the upper shell 2. The structure includes a support plate 3 fixedly connected to the top of both sides of the lower shell 1, and the left and right sides of the top of each support plate 3 are fixedly connected with a connecting seat 4, and the connecting seat 4 is fixedly connected with a connecting rod 5 at a position opposite to the connecting seat. The surface of the connecting rod 5 is respectively slidably sleeved with a card plate 1 6 and a card plate 2 7, and a protrusion 13 is fixedly connected to the upper position of the outer side of the card plate 1 6 and the card plate 2 7, and a spring 8 is fixedly connected to the bottom of the protrusion 13. The bottom of the spring 8 is fixedly connected to the top of the support plate 3, and a clamping head 9 is fixedly connected to the lower position of both sides of the upper shell 2. The outer surface of the clamping head 9 is connected to the clamping plate The inner arc surface formed by one 6 and the card plate two 7 is adapted to slide, and when the card head 9 slides between the card plates one 6 and the card plates two 7, it is elastically engaged by the spring 8, and the midpoint position around the bottom of the upper shell 2 is fixedly connected to the limiting column 10, and the top end surface of the lower shell 1 is provided with a limiting hole 11 which is adapted to be plugged with the limiting column 10. By setting the limiting column 10 to be engaged with the inner surface of the limiting hole 11, the position between the upper shell 2 and the lower shell 1 is limited, thereby realizing the role of limiting support, and a rubber pad 12 is bonded to the end surface of the top of the lower shell 1, and a through hole corresponding to the limiting hole 11 is provided inside the rubber pad 12. By setting the rubber pad 12, the gap between the lower shell 1 and the upper shell 2 is reduced.

[0025] Working principle: When the utility model is used, when the lower shell 1 and the upper shell 2 are connected, the clamp head 9 is clamped in the arc-shaped clamping groove formed by the clamping plate 1 6 and the clamping plate 2 7, and the convex block 13 is driven to shift its position by the action of the spring 8, so that the clamping plate 1 6 and the clamping plate 2 7 are mutually clamped on the outer surface of the clamp head 9;

[0026] When the upper shell 2 needs to be pulled out, it is only necessary to pull out the upper shell 2, thereby driving the clamping head 9 to move upward, and the clamping head 9 slides on the inner arc surface formed by the clamping plate 1 6 and the clamping plate 2 7. When the clamping head 9 moves upward, it will lift the clamping plates 1 6 and the clamping plates 2 7 on both sides, so that the clamping plates 1 6 and the clamping plates 2 7 slide and rotate on the outer surface of the connecting rod 5, and compress the spring 8 through the protrusion 13, and then pull the clamping head 9 out completely, thereby achieving the purpose of quickly pulling out the upper shell, so that it can be used quickly, and by setting the limiting column 10 to clamp on the inner surface of the limiting hole 11, the position between the upper shell 2 and the lower shell 1 is limited, thereby achieving the role of limiting support.
