Description

Technical Field

[0001] This utility model relates to the field of air sampler bracket technology, and in particular to a variable-form air sampler bracket. Background Technology

[0002] Chinese Patent Publication No. CN222789290U discloses an adjustable air sampler support, including a sampler body. Adjustment plates and adjustment base plates are connected to the outer walls of both sides of the sampler body. The adjustment plates are located directly above the adjustment base plates. Test tubes are inserted into the adjustment plates through test tube insertion holes and supported by the adjustment base plates, thereby setting up the test tubes for sampling on both sides of the sampler. There is no need to use a separate test tube support, which improves the convenience of sampling operations.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: the device can be conveniently used with a sampler and sample absorption tube by adjusting the plug plate, but in the process of air sampling, more than one sampler is often used. The use of the adjusting plug plate can only be adapted to the assembly of the sample absorption tube, and it is not easy to adapt to multiple sample absorption tubes and multiple samplers. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology is not easy to adapt to different numbers of samplers and sample absorption tubes. To this end, we propose a variable form air sampler bracket.

[0005] To achieve the above objectives, this application adopts the following technical solution: a variable-form air sampler bracket, including a base plate, with side L-shaped supports fixed on both opposite sides of the base plate, side plates hinged to the top of each side L-shaped support, and sample absorption tube racks provided on the inner sides of each side plate, a front L-shaped support fixed on the side of the base plate away from the side L-shaped supports, and a rear L-shaped support fixed on the side of the base plate opposite to the front L-shaped support, with sampler frames hinged to the tops of both the front and rear L-shaped supports, the sampler frame including a flip plate, the flip plate being hinged to the tops of the front and rear L-shaped supports, an inner protrusion strip fixed to the inner side of the top of the flip plate, a hanging hole being provided through the inner protrusion strip and the front and rear L-shaped supports directly below, and fixing components provided on the sides of the flip plate and adjacent side plates.

[0006] Preferably, the fixing component includes an upper connecting block fixed to one side of the flip plate, and a lower connecting block fixed to one side of the side plate. When the side plate and the flip plate are in a vertical state, the lower connecting block is located directly below the upper connecting block, and a screw threaded through the upper connecting block and the lower connecting block.

[0007] Preferably, the sample absorption tube holder includes a limiting plate hinged to the top of the inner side of the side plate. The limiting plate has evenly spaced limiting holes inside. U-shaped rods are hinged to both sides of the limiting plate. A locking block is fixed at the center of the bottom end of the U-shaped rod. A locking hole is opened inside the side plate and is located below the limiting plate.

[0008] Preferably, the height of the side plate is less than half the length of the bottom plate, and after the card block is inserted into the card hole, the limiting plate and the side plate are vertically distributed.

[0009] Preferably, two parallel adhesive strips are fixed on the outer side of the sampler frame on the rear L-shaped support, and two parallel flexible strips are fixed on the bottom end of the base plate away from the adhesive strips. The adhesive strips and the flexible strips can be bonded together.

[0010] Preferably, the base plate, side L-shaped support, front L-shaped support, and rear L-shaped support are an integrated structure. The height of the front L-shaped support is less than the height of the rear L-shaped support, and the length of the side L-shaped support is less than the height of the front L-shaped support, to prevent the flip plate from tilting up after folding. A connecting sleeve is fixed at the center of the bottom end of the base plate.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, multiple air samplers can be hung through the suspension holes of the sampler rack, and the limiting holes of the sample absorption tube rack can accommodate sample absorption tubes of different specifications, enabling flexible installation of various sampling devices. Relying on the hinged design of the side plate, sampler rack, and sample absorption tube rack, and with the screw removal and locking of the fixing components, each part can be folded inwards. This allows for selective deformation and unfolding of the entire support according to the required number of samplers and sample absorption tubes. Simultaneously, with the adhesive and flexible adhesive strips, the support can be retracted into a flat structure, significantly reducing space occupation when not in use and facilitating transport. Furthermore, in the unfolded state, the screw connection ensures structural stability, the integrated design of the base plate and support enhances strength, and the connecting sleeve can connect to a tripod to adapt to different height scenarios, balancing sampling stability with flexible deformation.

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] Reference Figures 1-6 As shown, this utility model provides a technical solution: a variable-form air sampler bracket, including a base plate 1, with side L-shaped supports 2 fixed on both opposite sides of the base plate 1, and side plates 3 hinged to the top of each side L-shaped support 2. Sample absorption tube racks 4 are provided on the inner side of each side plate 3. A front L-shaped support 5 is fixed on the side of the base plate 1 away from the side L-shaped supports 2, and a rear L-shaped support 6 is fixed on the side of the base plate 1 opposite to the front L-shaped support 5. Sampler racks 7 are hinged to the top of both the front L-shaped support 5 and the rear L-shaped support 6. The sampler rack 7 includes a flip plate 71, which is hinged to the top of the front L-shaped support 5 and the rear L-shaped support 6. An inner protrusion 72 is fixed to the inner side of the top of the flip plate 71. A hanging hole 73 is provided between the inner protrusion 72 and the front L-shaped support 5 and the rear L-shaped support 6 directly below. Fixing components 8 are provided on the sides of the flip plate 71 and the adjacent side plates 3.

[0023] Using the sampler rack 7, common air samplers can be directly inserted into the hanging hole 73 via the hooks on the back. At least two samplers can be hung on the outer sides of both the front and rear flip plates 71 as needed, maximizing the use of the support structure. Using the sample absorption tube rack 4, the sample absorption tube can be vertically inserted into the base plate 1, achieving adaptable installation for different numbers of samplers and sample absorption tubes, thus achieving the effect of adaptable deformation. At the same time, the hinged design of the side plate 3 and the sampler rack 7 allows the entire support to be folded inward to form a relatively flat sheet shape with the base plate 1, so that it can be folded and transported when not in use, reducing the overall space occupation and improving its convenience.

[0024] Reference Figure 2 , Figure 3 As shown, in this embodiment: the fixing component 8 includes an upper connecting block 81 fixed to one side of the flip plate 71, and a lower connecting block 82 fixed to one side of the side plate 3. When the side plate 3 and the flip plate 71 are in a vertical state, the lower connecting block 82 is located directly below the upper connecting block 81, and a screw 83 is threaded through the upper connecting block 81 and the lower connecting block 82.

[0025] The screw 83 is used to establish a secure connection between the upper connecting block 81 and the lower connecting block 82, ensuring the stability of the sampler and sample absorption tube and preventing them from falling and getting damaged. The base plate 1, together with the side plate 3 and the adjacent flip plate 71, forms a stable triangular area, which ensures that the side plate 3 and the flip plate 71 are securely fixed after being unfolded, so as to realize the stable insertion and installation of the sample absorption tube. At the same time, the number of unfolded side plates 3 and flip plates 71 can be selected according to the number of samplers and sample absorption tubes used.

[0026] Reference Figure 4 As shown, the sample absorption tube holder 4 includes a limiting plate 41 hinged to the top of the inner side of the side plate 3. Limiting holes 42 are evenly opened inside the limiting plate 41. U-shaped rods 43 are hinged to both sides of the limiting plate 41. A locking block 44 is fixed at the center of the bottom end of the U-shaped rods 43. A locking hole 45 is opened inside the side plate 3. The locking hole 45 is located below the limiting plate 41.

[0027] By utilizing the hinge design of limiting plate 41 and U-shaped rod 43, the limiting plate 41 itself can be folded inward against the inner wall of side plate 3, so that side plate 3 can be smoothly folded onto base plate 1, realizing the foldable effect of the bracket structure and reducing the space occupied when not in use. At the same time, the design of limiting hole 42 can be used to design the size of common sample absorption tube specifications on the market, improving the adaptability of the bracket for subsequent use. Together with base plate 1, the sample absorption tube rack 4 can fix sample absorption tubes of different specifications during use.

[0028] Reference Figure 4As shown, the height of the side plate 3 is less than half the length of the bottom plate 1. After the card block 44 is inserted into the card hole 45, the limiting plate 41 and the side plate 3 are vertically distributed.

[0029] By limiting the height of the side plate 3, it is ensured that the side plate 3 can be folded without affecting the folding of the sample absorption tube rack 4, avoiding positional interference between the two sample absorption tube racks 4 on the left and right sides, and reducing the difficulty of subsequent folding and compression.

[0030] Reference Figure 2 As shown, two parallel adhesive strips 9 are fixed on the outer side of the sampler frame 7 on the rear L-shaped support 6, and two parallel flexible strips 10 are fixed on the bottom end of the base plate 1 away from the adhesive strips 9. The adhesive strips 9 and flexible strips 10 can be bonded together.

[0031] By utilizing the adhesive strip 9, after the last sampler frame 7 is folded onto the base plate 1, the entire support can be fixed by the bonding between the adhesive strip 9 and the flexible strip 10, so that the support can be transformed from a cubic structure into a flat structure, reducing the overall size of the structure and effectively preventing it from loosening during folding.

[0032] Reference Figures 1-3 As shown, the base plate 1, the side L-shaped support 2, the front L-shaped support 5, and the rear L-shaped support 6 are an integral structure. The height of the front L-shaped support 5 is less than the height of the rear L-shaped support 6, and the length of the side L-shaped support 2 is less than the height of the front L-shaped support 5. This is so that when the side plate 3 and the flip plate 71 are folded later, the flip plate 71 will not tilt up, thus ensuring the integrity of the flat structure after folding. A connecting sleeve 11 is fixed at the center of the bottom end of the base plate 1.

[0033] By utilizing the connecting sleeve 11, the bracket can be connected to commercially available or compatible tripods, thereby ensuring that the bracket can be used at different heights. The integrated structure ensures the overall strength of the base plate 1 and guarantees its service life.

[0034] Working principle: When in use, the connecting sleeve 11 is fixed to the tripod with threads or fasteners, and the hook on the back of the sampler is inserted into the hanging hole 73, so that the sampler can be hung on the outside of the flip plate 71 for fixation. Then, the sample absorption tube is inserted into the corresponding limiting hole 42 according to the specifications, so that the bottom end of the sample absorption tube is placed on the top of the base plate 1, thus fixing the sample absorption tube. Then, the sampler and the sample absorption tube are connected for use through the sampling connecting tube and other components.

[0035] When folding, first turn the screw 83 upwards to separate the bottom end of the screw 83 from the lower connecting block 82. Then, slightly lift the limiting plate 41 to move the locking block 44 out of the locking hole 45, as shown in the attached diagram. Figure 6As shown, the U-shaped rod 43 is flipped along direction C, then the limiting plate 41 is flipped along direction D, and the side plate 3 is folded along direction E to the top of the bottom plate 1. The above operation is repeated on the other side of the sample absorption tube holder 4 and the side plate 3, thus realizing the folding of the side plate 3 and the sample absorption tube holder 4, as shown in the attached figure. Figure 5 As shown, after flipping the flip plate 71 away from the adhesive strip 9 along direction A, flip the other flip plate 71 along direction B onto the flip plate 71 just flipped. Finally, tighten the adhesive strip 9 and make the adhesive surface of the adhesive strip 9 and the soft strip 10 adhere together, thus achieving the complete folding of the bracket.

[0036] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
