Specific embodiment

For the ease of the understanding of those skilled in the art, below with reference to examples and drawings 1-6 to the utility model make into The explanation of one step, the content that embodiment refers to not are the restriction to the utility model.

As shown in figures 1 to 6, a kind of support device of gas sampling absorption bottle, including sampler shell 1, further include being resisted against The absorption bottle rack of the side wall of sampler shell 1, the absorption bottle rack include sequentially connected first support plate 2,3 and of side plate Second support plate 4, the side plate 3 are connect with the side wall of sampler shell 1, first support plate 2 offer shape it is identical and Contrary the first support hole 5 and the second support hole 6, first support hole 5 and the second support hole 6 are used to support absorption Bottle, first support hole 5 and the second support hole 6 are arranged side by side.

The support device of the gas sampling absorption bottle of the utility model (is not marked in conjunction with existing sampler, absorption bottle in figure Number) and silicone tube (unlabeled in figure) in use, place absorption bottle using the first support hole 5 and the second support hole 6, make adjacent Two absorption bottles it is contrary so that the silicone tube for being connected to two neighboring absorption bottle is U-shaped, avoiding silicone tube bending causes Gas circulates unsmooth problem, it is ensured that sampler steadily collects gas；Absorption bottle rack is resisted against to the side of sampler shell 1 On wall, convenient for collecting gas to sampler using absorption bottle, sampling efficiency is improved.In the present embodiment, first support hole 5 Quantity with the second support hole 6 is 1, in other embodiments, the quantity in first support hole 5 and the second support hole 6 It is settable multiple, and first support hole 5 and the second support hole 6 are disposed adjacent.

The absorption bottle rack is in " Contraband " type, and first support plate 2, side plate 3 and the second support plate 4 are integral type knot Structure.

In the present embodiment, " Contraband " type bracket ratio " Γ " type bracket of setting is more advantageous to protection absorption bottle, prevents from absorbing Bottle is collided by external object and is damaged.First support plate 2, side plate 3 and the second support plate 4 are an integral structure, i.e., " Contraband " Type bracket is an integral structure, and is improved the integral strength for absorbing bottle rack, is improved the production efficiency for absorbing bottle rack.

Second support plate 4 offers the first accommodating hole 7 and the second accommodating hole 8, the orthographic projection of first accommodating hole 7 Face is overlapped with the frontal plane of projection in the first support hole 5, the orthographic projection of the frontal plane of projection of second accommodating hole 8 and the second support hole 6 Face is overlapped.

When the first accommodating hole 7 and the second accommodating hole 8 being arranged guarantee that the support device places longer absorption bottle, absorb The bottom of bottle can pass through the first accommodating hole 7 or the second accommodating hole 8, keep the matched absorption bottle of the support device more, avoid Absorption bottle is shaken and damages after being resisted against the second support plate 4.

The hole wall in first support hole 5 and the hole wall in the second support hole 6 are pasted with the flexibility for protecting absorption bottle Gasket 9.

In the present embodiment, the flexible gasket 9 of setting play a part of buffer external force, first with not set flexible gasket 9 Support hole 5 or the second support hole 6 are compared, avoid the absorption bottle by 6 support of the first support hole 5 or the second support hole be shaken and Damage.

The side that the sampler shell 1 is connect with side plate 3 is provided with convex block 10, and the convex block 10 opens up along the vertical direction There is card hole 11；The side that the side plate 3 is connect with sampler shell 1 is provided with hook elastic slice 12, the hook elastic slice 12 and card The hole wall in hole 11 contradicts.

In such a way that hook elastic slice 12 and the hole wall of card hole 11 contradict, it is connected to sampler shell 1 with absorption bottle bracket Together, it is connected firmly, bottle rack can will be absorbed after sampling and is taken apart from sampler shell 1, convenient for assembling and transport. Compared with the mode of threaded connection, the mode that the hook elastic slice 12 of the present embodiment and the hole wall of card hole 11 contradict is in assembly and disassembly It is easier in the process, quick, it can assembly and disassembly without tools such as screwdrivers.

The side that the sampler shell 1 is connect with side plate 3 offers first through hole 13, and the side plate 3 offers and the Second through-hole 14 of one through-hole 13 connection, the support device further includes being arranged in the clamping of first through hole 13 and the second through-hole 14 Part 15, the sampler shell 1 are clamped by shackle member 15 and the absorption bottle bracket.

In the present embodiment, the sampler shell 1 is clamped by shackle member 15 and the absorption bottle bracket, in conjunction with hook Elastic slice 12 and the hole wall of card hole 11 contradict, and are clamped sampler shell 1 with absorption bottle bracket stronger, the support is avoided to fill It sets and falls off in use and damage absorption bottle.

The shackle member 15 include swivel head 151, connect with swivel head 151 rod piece 152, be set to rod piece 152 outside The pin 153 of wall and be sheathed on rod piece 152 outer wall spring 154, the spring 154 is set to swivel head 151 and pin Between 153, the side wall of the first through hole 13 offers the locked groove 16 for contradicting with pin 153；The swivel head 151 and bullet Spring 154 is all set in the side of the side plate 3 far from sampler shell 1, and the spring 154 is with side plate 3 against the rod piece 152 are arranged in the first through hole 13 and the second through-hole 14.

In use, twisting swivel head 151, swivel head 151 drive rod piece 152 to rotate manually, pin on rod piece 152 is allowed 153 alignment locked grooves 16, then swivel head 151 is pressed to the direction close to sampler shell 1, then twist swivel head 151, then in bullet Under spring 154 acts on, reversed elastic force is applied to swivel head 151, the side wall of pin 153 and the side wall of locked groove 16 contradict, and reach sealed State makes sampler shell 1 securely be connected together with bottle rack is absorbed, and improves sampler shell 1 and connect with bottle rack is absorbed Stability, prevent absorb bottle rack surprisingly fall off from sampler shell 1.It needs sampler shell 1 and absorbs bottle rack When separation, presses and reversely twisting swivel head 151 applies reversed elastic force to swivel head 151, make rod piece under the effect of spring 154 Pin 153 on 152 is withdrawn from locked groove 16, thus the state that unlocks, the shackle member 15 of setting is convenient for sampler shell 1 With the assembly and disassembly between absorption bottle rack.Further, the swivel head 151 is fixedly connected with rod piece 152.

The locked groove 16 is in " J " type.

In the present embodiment, locked groove 16 is arranged to " J " type, convenient for guiding the moving direction and swivel head of pin 153 151 twisting direction, and pin 153 contradicts at the hook end of " J " type locked groove 16, cooperates the effect of spring 154, snap effect It is stronger.In other embodiments, the locked groove 16 can be L-shaped.

Above-described embodiment is the preferable implementation of the utility model, and in addition to this, the utility model can be with other sides Formula realizes that any obvious replacement is in the protection model of the utility model without departing from the concept of the premise utility Within enclosing.
