Description

Technical Field

[0001] The utility model relates to the technical field of service life detection of a poison filter box, in particular to an on-site service life detection device for a poison filter box. Background Art

[0002] Gas filter cartridges can be cylindrical or trapezoidal in shape, made of plastic, and filled with a certain type of activated carbon agent. They remove dust, toxic and harmful gases from the air through physical adsorption and chemical reaction principles for human breathing. They are usually used in conjunction with gas masks and are generally effective for 5 years. The surface of the gas filter canister is often coated with alkali-proof paint. The gas filter cartridge has a smoke filter layer inside to filter out smoke particles. The filter element is made of filter paper, glass fiber, or other synthetic materials. The gas filter cartridge can be filled with the corresponding type of activated carbon to absorb different toxic gases. When the gas filter cartridge is used on site, the service life of the gas filter cartridge is usually tested using life detection equipment.

[0003] When using, the existing life detection equipment is usually worn on the user's body. The air in the filter box is sucked into the detection cavity inside the detection equipment through an air pump for detection. If a certain gas being detected exceeds the standard, the filter box needs to be replaced in time and the use time of the filter box needs to be recorded. However, in actual use, in order not to affect the operator's operation, the life detection equipment is usually worn on the outside of the operator's body, but does not have a protective structure, which makes it easy to be hit during use, thereby affecting the use of the life detection equipment. For this reason, we propose an on-site service life detection equipment for filter boxes. Utility Model Content

DETAILED DESCRIPTION

[0023] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0024] Example:

[0025] like Figure 1-Figure 5 As shown, a device for detecting the service life of a gas filter cartridge on site comprises a first box body 1, a second box body 2 is provided on one side of the first box body 1, an air inlet 3 and an air outlet 4 are respectively provided at the top end of the second box body 2, a threaded hole 5 is opened on the top of the second box body 2, a fixed limiting sleeve 7 is symmetrically provided on one side of the second box body 2, a connecting protection mechanism 6 is movably connected to the inner side of the fixed limiting sleeve 7, and a bolt is provided between the top end of the connecting protection mechanism 6 and the top of the second box body 2.

[0026] The working principle of the above technical solution is as follows:

[0027] During use, the connecting protection mechanism 6 is inserted into the inner side of the fixed limiting sleeve 7 so that the connecting protection mechanism 6 and the surface of the second box body 2 fit together, and then the connecting protection mechanism 6 and the second box body 2 are connected and fixed by bolts, thereby providing stable protection for the whole and easy operation.

[0028] In another embodiment, Figure 2 As shown, fixed limit blocks 8 are provided at the upper and lower ends of the side where the first box body 1 and the second box body 2 are close to each other, and a movable limit sleeve block 9 is movably sleeved on the outer surface of the fixed limit block 8. A fixed through hole 10 is provided at one end of the movable limit sleeve block 9 close to the side of the first box body 1, and a fixed positioning mechanism 11 is fixedly connected to the top of the first box body 1.

[0029] It is convenient for the movable limiting block 9 to be sleeved on the outer surface of the fixed limiting block 8, and at the same time, the fixed through hole 10 can be connected and matched with the fixed positioning mechanism 11, so that the first box body 1 and the second box body 2 can be quickly connected and matched, and the whole can be installed and fixed, which is easy to operate.

[0030] In another embodiment, Figure 4 As shown, the connection protection mechanism 6 includes a connection mounting plug 14, the surface of the connection mounting plug 14 is fixedly connected to the connection mounting plate 13, the top middle part of the connection mounting plate 13 is fixedly connected to the movable connection arm 12, and the surface of the connection mounting plate 13 is symmetrically provided with a buffer spring 15, and the other end of the buffer spring 15 is fixedly connected to the connection protection plate 16.

[0031] When the connecting protection plate 16 is hit by a collision, the connecting protection plate 16 can move to compress the buffer spring 15, and the buffer protection is performed by the contraction of the buffer spring 15, which is easy to operate.

[0032] In another embodiment, Figure 4 As shown, the outer surface of the connecting and installing plug-in block 14 and the inner surface of the fixed limiting sleeve block 7 are slidably fitted with each other.

[0033] The installation plug-in block 14 can be stably inserted into the inner side of the fixed limiting sleeve block 7 to facilitate connection and fit, thereby enabling quick connection and easy operation.

[0034] In another embodiment, Figure 4 As shown, a fixed sleeve 17 is provided on the surface edge of the connecting mounting plate 13, and a connecting guide plug 18 is fixedly connected to the side of the connecting protective plate 16 close to the connecting mounting plate 13, and the outer surface of the connecting guide plug 18 and the inner side of the fixed sleeve 17 slide and fit with each other.

[0035] When the connecting protection plate 16 is moved, the connecting guide plug block 18 can be moved inside the fixed sleeve block 17 , which is easy to operate.

[0036] In another embodiment, Figure 5 As shown, the fixed positioning mechanism 11 includes a connecting sleeve block 19, and the internal movably connected to the connecting sleeve block 19 is a movable rod 20, and the outer surface of the movable rod 20 is fixedly sleeved with a force sleeve disk 21, and a force spring 22 is fixedly connected between one side of the force sleeve disk 21 and the inner end of the connecting sleeve block 19, and the end of the movable rod 20 away from the movable limit sleeve block 9 is fixedly connected to a connecting pull ring 23.

[0037] It is convenient to pull the connecting pull ring 23, drive the movable rod 20 and the force sleeve 21 to move, compress the force spring 22, and make the end of the movable rod 20 retract and move toward the inside of the connecting sleeve block 19, thereby quickly adjusting.

[0038] In another embodiment, Figure 3 and Figure 5 As shown, the outer side of the other end surface of the movable insertion rod 20 and the inner side of the fixed through hole 10 are slidably fitted with each other.

[0039] This facilitates the stable insertion of one end of the movable insertion rod 20 into the inner side of the fixed through hole 10 , making the operation convenient.

[0040] The working principle of the present invention is as follows: during use, the whole body moves with the user. When the connecting guard plate 16 is hit, the connecting guard plate 16 can drive the connecting guide plug 18 to move inside the fixed sleeve 17. At the same time, the connecting guard plate 16 can compress the buffer spring 15, and the contraction of the buffer spring 15 can buffer the force caused by the collision, thereby providing protection for the first box body 1 and the second box body 2, avoiding damage to the internal components of the first box body 1 and the second box body 2. When the internal components of the first box body 1 and the second box body 2 need to be repaired and maintained , pull the connecting pull ring 23, drive the movable insertion rod 20 and the force sleeve 21 to move, compress the force spring 22, so that the end of the movable insertion rod 20 can be retracted and moved toward the inside of the connecting sleeve block 19, thereby quickly adjusting, and then the movable limit sleeve block 9 is moved laterally, so that the movable limit sleeve block 9 can be detached from the outer surface of the fixed limit block 8, and no longer restrict the connection between the fixed limit blocks 8, so that the first box body 1 and the second box body 2 can be quickly disassembled and separated, and the internal components of the first box body 1 and the second box body 2 can be quickly inspected and maintained, and the operation is convenient.

[0041] The above embodiments merely represent specific implementation methods of the present invention. Although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
