Technical realization elements of gas monitoring device for welding protection

Technical realization elements:

4. The purpose of the present utility model is to provide a gas monitoring device for pair welding protection, so as to solve the above-mentioned problems in the background art.

5. In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a gas monitoring device for assembled butt welding protection, comprising a gas detection alarm and a mounting seat, the back of the gas detection alarm is fixedly connected with a block, so The outer wall of the locking block is provided with a locking groove, the mounting seat includes a housing, the outer wall of the housing is fixedly connected with a plurality of fixing ears, and the outer wall of the housing is provided with a locking groove adapted to the locking block, The housing is provided with a locking block, one end of the locking block penetrates the inner wall of the housing and is located in the slot, the locking block is matched with the locking groove, and the inner wall of the housing is fixedly connected with a first A spring, one end of the first spring abuts against the end surface of the lock block, the end face of the lock block penetrating the housing is set in an inclined plane, and a concave first inclined plane is provided on the inclined plane, and the top of the housing is provided with A movable rod, the bottom end of the movable rod is attached to the first inclined surface

6. Preferably, a second inclined surface is provided where the movable rod is attached to the first inclined surface, and the slope of the movable rod is adapted to the slope of the second inclined surface.

7. Preferably, the inner wall of the housing is located on both sides of the movable rod symmetrically and fixedly connected with two guide pieces, the top end of the movable rod is fixedly connected with a force block, and the connecting surface of the force block and the movable rod Larger than the end surface of the movable rod, the outer wall of the movable rod located in the shell is fixedly connected with the limit block.

8. Preferably, a second spring is fixedly connected to the inner wall of the housing, and the top end of the second spring abuts against the bottom surface of the limiting block.

9. Preferably, a casing is fixedly connected to the inner wall of the casing, one end of the first spring and the locking block are both located in the casing, and the casing is adapted to the size of the locking block.

10. Preferably, two ejector rods are symmetrically arranged inside the housing, the top end of the ejector rod penetrates the bottom of the slot, the bottom of the ejector rod is fixedly connected with a fixing plate, and the bottom of the fixing plate A third spring is fixedly connected, and the bottom end of the third spring is fixedly connected to the inner wall of the housing.

11. Preferably, the outer wall of the ejector rod is movably sleeved with a guide tube, and the top end of the guide tube is fixedly connected with the inner wall of the housing.

12. Compared with the prior art, the beneficial effects of this utility model are:

13.(1). This group of gas monitoring devices for welding protection, by setting up the mounting seat, clamping block, locking groove, clamping groove, locking block, first spring, movable rod, etc., when disassembling the gas detection alarm , Only need to press down the force block to make the movable rod push the lock block to move into the housing, until the lock block is out of the lock slot, the gas detection alarm can be removed upwards, the operation is simple, time-saving and labor-saving, and the use effect is good.

14.(2). This set of gas monitoring devices for welding protection uses a first inclined plane and a second inclined plane, and uses the guiding effect produced by the cooperation of the first inclined plane and the second inclined plane to press the movable rod downwards to When the locking block is contracted into the housing, the movement of the locking block can be made smoother.

15.(3). This set of gas monitoring devices for welding protection uses a third spring, a fixed plate, and an ejector rod. When the force receiving block is pressed down to make the locking block out of the locking groove, the ejector rod will be in the third spring. Move upward under the action of the, so that the block is lifted upwards, so that the locking groove and the locking block are staggered to avoid that the locking block is inserted into the locking groove again when the force-bearing block is released, which makes it easier to disassemble the gas detection alarm and can Complete the operation with one hand.
