[0022] It should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned drawings of this application are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. For the embodiments of this application described here, based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts should fall within the scope of protection of this application.

[0023] Referring to Figures 1 - 4 , the gas sensor aging rack includes an aging rack body 3 and a housing 1. The aging rack body 3 is fixed to the top of the housing 1 by bolts. Outer shells 2 are fixed to both sides of the housing 1 by bolts, and the outer shells 2 are fixed to the aging rack body 3. The outer shells 2 have an open structure at the bottom and one side. Connecting shafts 13 are rotatably connected to positions inside the outer shells 2 on both sides of the aging rack body 3. A cam 8 and a gear 14 are key-connected to the circumferential outer wall of the connecting shaft 13. A slide plate 11 is slidably connected inside the outer shell 2. Two universal wheels 12 are fixed to the bottom of the slide plate 11 by bolts. Two tension springs 10 are welded to the top of the slide plate 11, and the tension springs 10 are fixed to the outer shell 2. A driving assembly for rotating the connecting shaft 13 is provided inside the housing 1. A handle assembly for pulling the aging rack body 3 is provided on one side of the aging rack body 3. By driving the connecting shaft 13 to rotate through the driving assembly, the connecting shaft 13 will drive the cam 8 to rotate, causing the protruding part of the cam 8 to rotate downward, so that the protruding part of the cam 8 pushes the slide plate 11 downward. The slide plate 11 will stretch the tension spring 10 and drive the universal wheels 12 to move downward, causing the universal wheels 12 to contact the ground and lift the outer shell 2 and the housing 1, so that the outer shell 2 and the housing 1 are separated from the ground contact. Then the aging rack body 3 can be moved through the universal wheels 12, which is convenient for moving the aging rack, eliminating the need for staff to carry it, avoiding damage to the staff, and improving the safety of moving the aging rack.

[0024] In the present utility model, the driving assembly includes a threaded rod 18 which is rotatably connected inside the housing 1. A connecting plate 17 is threadedly connected to the circumferential outer wall of the threaded rod 18. Slide grooves 16 are formed on both sides of the housing 1. Both ends of the connecting plate 17 pass through the slide grooves 16 and extend into the outer shell 2, enabling the connecting plate 17 to move along the groove direction of the slide grooves 16. On one side of the connecting plate 17 located inside the outer shell 2, racks 15 are fixed by bolts. The racks 15 are meshed with the gears 14. By rotating the threaded rod 18, the threaded engagement between the threaded rod 18 and the connecting plate 17 causes the connecting plate 17 to move along the slide grooves 16. The connecting plate 17 drives the rack 15 to move. The rack 15 drives the gear 14 to rotate through the meshing with the gear 14, and the gear 14 drives the connecting shaft 13 to rotate;

[0025] The handle assembly includes a plurality of bumps 6. The plurality of bumps 6 are all fixed to one side of the aging rack body 3 by bolts. A push handle 7 is rotatably connected between the plurality of bumps 6. Two magnets 4 are bonded to the top of the push handle 7, and the magnets 4 are adsorbed to the aging rack body 3, fixing the push handle 7. A baffle 5 for limiting the push handle 7 is welded between the plurality of bumps 6. By rotating the push handle 7, the magnets 4 are separated from the adsorption of the aging rack body 3. At the same time, the baffle 5 limits the push handle 7. At this time, the aging rack body 3 can be pulled by the push handle 7 to move. When the push handle 7 is not in use, the push handle 7 is fixed by the adsorption between the magnet 4 and the aging rack body 3, thereby preventing the push handle 7 from rotating. Two telescopic rods 9 are fixed to the top of the slide plate 11 by bolts. The two telescopic rods 9 respectively pass through two tension springs 10, and one end of the telescopic part of the telescopic rod 9 is fixed to the outer shell 2. One end of the threaded rod 18 passes through the housing 1 and is welded with a knob for rotating the threaded rod 18, and the threaded rod 18 can be rotated by the knob.

[0026] Working principle: When in use, rotate the threaded rod 18. The threaded engagement between the threaded rod 18 and the connecting plate 17 causes the connecting plate 17 to move along the slide grooves 16. The connecting plate 17 drives the rack 15 to move. The rack 15 drives the gear 14 to rotate through the meshing with the gear 14. The gear 14 drives the connecting shaft 13 to rotate. The connecting shaft 13 drives the cam 8 to rotate, causing the convex part of the cam 8 to rotate downward. Thus, the convex part of the cam 8 pushes the slide plate 11 downward. The slide plate 11 stretches the tension spring 10 and drives the universal wheel 12 to move downward, making the universal wheel 12 contact the ground and jack up the outer shell 2 and the housing 1, causing the outer shell 2 and the housing 1 to be separated from the ground contact. Then rotate the push handle 7, separating the magnet 4 from the adsorption of the aging rack body 3. At the same time, the baffle 5 limits the push handle 7. At this time, the aging rack body 3 can be pulled by the push handle 7 to move through the universal wheel 12, facilitating the movement of the aging rack, eliminating the need for staff to carry it, avoiding damage to the staff, and improving the safety of the aging rack movement.
