Description

Technical Field

[0001] This utility model belongs to the technical field of atmospheric sampler brackets, and specifically relates to a special bracket for atmospheric samplers. Background Technology

[0002] Atmospheric sampler brackets are specialized support devices designed specifically for atmospheric monitoring equipment—atmospheric samplers. Their core function is to provide a stable and compliant mounting platform for the sampler, ensuring that the sampler can complete atmospheric sample collection according to preset requirements in various environments. They are an indispensable auxiliary device in the atmospheric monitoring system, directly affecting the accuracy of sampling data and the safety of the sampling process.

[0003] Currently, bolt-fastening is the most widely used mainstream method for connecting and assembling atmospheric samplers and their supports. This method achieves rigid fixation through bolt assemblies (including bolts, nuts, and washers) that pass through pre-drilled holes in the support platform and mounting holes in the atmospheric sampler base. From an operational convenience perspective, this connection method is highly dependent on tools. Disassembly and assembly require specialized tools such as wrenches and screwdrivers. In remote monitoring locations (such as mountainous areas or suburbs), incomplete tooling can directly prevent sampler installation. Repeated disassembly and assembly can cause wear on bolt threads and stripping of the sampler base's screw holes. With increased use, the connection gap gradually increases, leading to decreased stability. Furthermore, when the orientation of the atmospheric sampler needs to be adjusted according to monitoring requirements, the existing support cannot securely lock the sampler in the adjusted orientation. This makes it easy for the atmospheric sampler to rotate unexpectedly during subsequent use. Once rotation occurs, it not only deviates from the preset sampling orientation, affecting the targeting and accuracy of atmospheric sample collection, but also causes a decrease in the overall stability of the sampler due to continuous rotation, interfering with normal atmospheric monitoring work.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a special bracket for atmospheric samplers to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a special bracket for an atmospheric sampler, including a sampler body and a support mechanism. A plug rod is fixedly installed at the bottom of the sampler body, and several limiting blocks are fixedly installed on the outer wall of the plug rod. Each limiting block has an insertion hole at its bottom. A support rod is fixedly installed on the top of the support mechanism, a connecting box is fixedly installed on the top of the support rod, a connecting shaft is fixedly installed on the bottom central axis inside the connecting box, a bearing is fixedly installed on the outer wall of the connecting shaft, a rotating block is installed on the outer wall of the bearing, an abutment groove is opened on the outer wall of the rotating block, an anti-slip part is threaded on one end of the connecting box, and a transmission column is fixedly installed on the top of the rotating block. The transmission column extends above the connecting box and is fixedly connected to a placement box. An elastic snap-fit ​​component is installed at the bottom of the placement box and around the transmission column. The placement box has an internal cavity and a number of slots on its top. The cavity communicates with the slots, and a baffle is installed inside the cavity and on one side of each slot.

[0007] Furthermore, the support mechanism includes a connecting seat, the support rod is fixedly installed on the top of the connecting seat, a plurality of support legs are rotatably installed on the bottom periphery of the connecting seat, a fixing rod is fixedly installed at the central axis of the bottom of the connecting seat, and a connecting rod is hinged to one end of each support leg.

[0008] Furthermore, a sliding ring is slidably mounted on the fixed rod, and the end of each connecting rod away from each supporting leg is hinged to the sliding ring.

[0009] Furthermore, one end of the connecting box is provided with a threaded hole and two sliding holes.

[0010] Furthermore, the anti-slip component includes an arc-shaped block, on the side of the arc-shaped block near the contact groove, a friction plate is fixedly installed, and the friction plate abuts against one side of the contact groove.

[0011] Furthermore, a screw is rotatably mounted on the end of the arc-shaped block away from the friction plate, and a slide rod is symmetrically fixedly mounted thereon. A knurled knob is fixedly mounted on the end of the screw away from the arc-shaped block.

[0012] Furthermore, the elastic snap-fit ​​component includes a circular block, a plurality of insert shafts are fixedly mounted on the top of the circular block, and an elastic element is fixedly mounted on the top of the circular block and around the plurality of insert shafts.

[0013] Furthermore, the end of the elastic element away from the circular block is fixedly installed at the bottom of the placement box, the insertion shaft extends into the cavity, and an anti-detachment block is installed on the top of the insertion shaft.

[0014] This utility model has the following beneficial effects: This invention uses several limiting blocks at the top of the cavity to restrict the vertical movement of the limiting blocks, and uses the insertion of relevant parts of the elastic snap-fit ​​component into the socket to restrict the rotation of the limiting blocks, thereby completing the installation between the sampler body and the placement box. This process can be completed without the use of tools, avoiding the problem of strong dependence on tools in traditional installation, and also improving the efficiency of installation.

[0015] This invention allows the operator to manually rotate the anti-slip component to release its restriction on the rotation of the rotating block. After the sampler body is properly oriented, the anti-slip component is rotated in the opposite direction, causing it to move closer to the rotating block and abut against the contact groove. This restricts the free rotation of the rotating block and fixes the orientation of the sampler body, ensuring that the sampler body always remains in the preset position and avoiding data distortion caused by orientation deviation.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0021] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0022] Please see Figures 1-9 As shown, this utility model is a special bracket for an atmospheric sampler, including a sampler body 1 and a support mechanism 2. A plug rod 3 is fixedly installed at the bottom of the sampler body 1, and a plurality of limiting blocks 4 are fixedly installed on the outer wall of the plug rod 3. Each limiting block 4 has a plug hole 401 at its bottom. A support rod 5 is fixedly installed on the top of the support mechanism 2. A connecting box 6 is fixedly installed on the top of the support rod 5. A connecting shaft 7 is fixedly installed on the central axis at the bottom inside the connecting box 6. A bearing 8 is fixedly installed on the outer wall of the connecting shaft 7. A rotating block 9 is installed on the outer wall of the bearing 8. An abutment groove 901 is opened on the outer wall of the rotating block 9. An anti-slip part 10 is threaded on one end of the connecting box 6. A transmission column 11 is fixedly installed on the top of the rotating block 9. The transmission column 11 extends above the connecting box 6 and is fixedly connected to the placement box 12. An elastic snap-fit ​​member 13 is installed at the bottom of the placement box 12 and around the transmission column 11. The placement box 12 has a cavity 1201 inside and a number of slots 1202 on the top of the placement box 12. The cavity 1201 communicates with the number of slots 1202. A baffle 14 is installed in the cavity 1201 and on one side of each slot 1202.

[0023] When needed, first move the support mechanism 2 to the target monitoring point and unfold it to ensure it is stably placed on the ground. Then, pull down the elastic locking member 13. The elastic potential energy inside the elastic locking member 13 increases, causing the portion of the elastic locking member 13 located in the cavity 1201 of the placement box 12 to move out, but not detach from the placement box 12. This provides space for the rotation of the insertion rod 3 and several limiting blocks 4. At the same time, pick up the sampler body 1 and align the several limiting blocks 4 on the bottom insertion rod 3 with several slots 1202. Then, the several limiting blocks 4 pass through the several slots 1202, so that the insertion rod 3 and several limiting blocks 4 are located in the cavity 1201. Next, rotate the sampler body 1. The sampler body 1 drives the insertion rod 3 and several limiting blocks 4 to rotate in the cavity 1201 until one side of the several limiting blocks 4... When all of them are in contact with several baffles 14, the movement of several limiting blocks 4 in the vertical direction is restricted by the action of the top of the cavity 1201. Several through holes are provided in the placement box 12, which provide space for the sliding of the elastic snap-fit ​​13. At this time, the insertion holes 401 on several limiting blocks 4 will be aligned with the through holes on the placement box 12. The elastic snap-fit ​​13 is released, and its elastic property is released. Then, the relevant parts of the elastic snap-fit ​​13 can be inserted into the insertion holes 401, so that the several limiting blocks 4 are restricted in the rotation direction. Thus, the installation between several limiting blocks 4, insertion rod 3 and sampler body 1 and placement box 12 is completed. This process can be completed without the use of tools, avoiding the problem of strong dependence on tools in traditional installation, and also improving the efficiency of installation. When the orientation of the sampler body 1 needs to be adjusted, the operator manually rotates the anti-slip part 10. The rotation of the anti-slip part 10 causes it to move away from the rotating block 9 under the action of the connecting box 6. Then, the operator manually rotates the sampler body 1 again. The sampler body 1 drives the insertion rod 3 and several limiting blocks 4 to rotate. The limiting blocks 4 drive the elastic locking part 13 to rotate, which in turn drives the placement box 12 to rotate. The placement box 12 then drives the transmission column 11 to rotate, which in turn drives the rotating block 9 at the bottom to rotate. The connecting shaft... 7 supports the inner ring of bearing 8, and then the rotating block 9 can rotate freely under the action of the outer ring of bearing 8. Then the sampler body 1 can rotate freely. After the orientation of the sampler body 1 is adjusted, the anti-slip part 10 is rotated in the opposite direction by hand, so that the anti-slip part 10 can move closer to the rotating block 9 and abut against the contact groove 901, thereby restricting the free rotation of the rotating block 9 and fixing the orientation of the sampler body 1, ensuring that the orientation of the sampler body 1 is always kept in the preset position, and avoiding the distortion of sampling data caused by orientation deviation.

[0024] In one embodiment, the support mechanism 2 includes a connecting seat 201, the support rod 5 is fixedly installed on the top of the connecting seat 201, a plurality of support legs 202 are rotatably installed on the bottom periphery of the connecting seat 201, a fixing rod 203 is fixedly installed at the bottom central axis of the connecting seat 201, and a connecting rod 204 is hinged to one end of each support leg 202.

[0025] A sliding ring 205 is slidably mounted on the fixed rod 203, and one end of each connecting rod 204 away from each supporting leg 202 is hinged to the sliding ring 205.

[0026] During the unfolding of the support leg 202, the operator only needs to push the sliding ring 205 downward, causing the sliding ring 205 to slide downward along the axis of the fixed rod 203. Since the sliding ring 205 is hinged to each connecting rod 204, the downward movement of the sliding ring 205 will generate a downward pulling force on the connecting rod 204. The other end of the connecting rod 204 is hinged to the support leg 202, and the support leg 202 can rotate around the bottom periphery of the connecting seat 201. Therefore, the pulling force will be converted into a force that pushes the support leg 202 to rotate outward. As the sliding ring 205 continues to move downward, each support leg 202 will open outward synchronously along the periphery of the connecting seat 201 until the sliding ring 205 slides to the preset limit position of the fixed rod 203, and the connecting rod 204 is in a taut state. Then, each support leg 202 is placed on the ground, and finally the support mechanism 2 forms a stable support structure, providing a solid bearing foundation for the sampler body 1 above.

[0027] In one embodiment, for the connecting box 6, one end of the connecting box 6 is provided with a threaded hole 601 and two sliding holes 602.

[0028] The anti-slip component 10 includes an arc-shaped block 1001, on which a friction plate 1002 is fixedly installed, and the friction plate 1002 abuts against one side of the contact groove 901.

[0029] The arc-shaped block 1001 is rotatably mounted with a screw 1003 at one end away from the friction plate 1002 and is symmetrically fixedly mounted with a slide rod 1004. A knurled knob 1005 is fixedly mounted at one end of the screw 1003 away from the arc-shaped block 1001.

[0030] When it is necessary to release the rotation restriction on the rotating block 9, the operator manually rotates the knurled knob 1005. The knurled texture of the knob 1005 increases the friction for the hand, making it easier for the operator to apply force. The knurled knob 1005 then rotates the screw 1003, which passes through the threaded hole 601 of the connecting box 6. The internal thread of the threaded hole 601 meshes with the external thread of the screw 1003. When the screw 1003 rotates, it will displace axially along the threaded hole 601. Simultaneously, the sliding rods 1004, symmetrically fixed at the end of the arc-shaped block 1001 away from the friction plate 1002, pass through two corresponding sliding holes 602 in the connecting box 6. The sliding rods 1004 and the sliding holes 602 form a sliding fit, providing guidance for the axial movement of the screw 1003 and preventing the screw 1003 from shifting with rotation. As the screw 1003 rotates continuously within the threaded hole 601 and moves outward, the screw 1003 drives the arc-shaped block 1001 to move away from the rotating block 9 in sync. The friction plate 1002 fixed on the side of the arc-shaped block 1001 near the contact groove 901 also moves accordingly. Thus, the friction plate 1002, which was originally in contact with the inner wall of the contact groove 901, gradually separates from the contact groove 901, and the friction between the two disappears. The friction plate 1002 is made of rubber. When the friction plate 1002 is completely separated from the contact groove 901, the rotating block 9 loses the resistance of the friction plate 1002 and can rotate freely with the cooperation of the bearing 8. This allows the orientation of the sampler body 1 to be adjusted. Meanwhile, the slide rod 1004 remains sliding within the slide hole 602, restricting the rotation trend of the arc-shaped block 1001 and ensuring that the friction plate 1002 is always facing the contact groove 901 throughout the entire unlocking process. Similarly, after adjusting the orientation of the sampler body 1, the knurled knob 1005 is rotated in the opposite direction, causing the screw 1003 to drive the arc block 1001 to move closer to the rotating block 9. The friction plate 1002 also gradually approaches the inner wall of the contact groove 901. When the knurled knob 1005 can no longer be rotated in the opposite direction, the friction plate 1002 is tightly against the contact groove 901. The friction between the two restricts the rotation trend of the rotating block 9.

[0031] In one embodiment, the elastic snap-fit ​​member 13 includes a circular block 1301, a plurality of insert shafts 1302 are fixedly mounted on the top of the circular block 1301, and an elastic element 1303 is fixedly mounted on the top of the circular block 1301 and around the plurality of insert shafts 1302.

[0032] The end of the elastic element 1303 away from the round block 1301 is fixedly installed at the bottom of the placement box 12, the insertion shaft 1302 extends into the cavity 1201, and an anti-detachment block 1304 is installed on the top of the insertion shaft 1302.

[0033] When the sampler body 1 needs to be installed, first pull the round block 1301 down by hand. Then the round block 1301 drives the elastic element 1303 (preferably a spring) to stretch, which increases the elastic potential energy of the elastic element 1303. It should be noted that the diameter of the anti-detachment block 1304 is larger than the diameter of the through hole on the placement box 12. The placement box 12 is also provided with a placement groove above the through hole. The placement groove provides space for the placement of the anti-detachment block 1304. At the same time, the round block 1301 drives the insertion shaft 1302 and the anti-detachment block 1304 to move until the anti-detachment block 1304 enters the placement groove of the placement box 12. At this time, the top of the anti-detachment block 1304 is flush with the bottom of the cavity 1201, thus providing space for the rotation of the insertion rod 3 and several limiting blocks 4. When the limiting block 4 rotates within the cavity 1201 until it contacts the baffle 14, and the insertion hole 401 on the limiting block 4 aligns with the insertion shaft 1302, the operator releases the round block 1301. The stretched elastic element 1303 releases its elastic potential energy, generating an upward reset force that pulls the round block 1301 upward in the vertical direction. The round block 1301 drives several insertion shafts 1302 fixed at the top and the anti-disengagement block 1304 to slide upward synchronously. The insertion shaft 1302 is positioned... The insertion shaft 1302 and the anti-detachment block 1304 are inserted into the cavity 1201 and inserted into the insertion hole 401 of the limiting block 4 in the through hole of the placement box 12. This restricts the rotation of the limiting block 4 in the cavity 1201. At the same time, the elastic member 1303 returns to its natural extended state. Through continuous elastic tension, the insertion shaft 1302 and the anti-detachment block 1304 are stably held in the insertion hole 401 to prevent the insertion shaft 1302 from falling off due to outdoor vibration or slight collision.

[0034] Working principle: First, push the sliding ring 205 downward so that it moves down along the fixed rod 203. Through the connecting rod 204, drive each support leg 202 to open outward synchronously under the action of the connecting seat 201. Then place the support leg 202 on the ground to complete the support of the bracket. Next, pull down the round block 1301. The round block 1301 stretches the elastic element 1303 and drives the insertion shaft 1302 and the anti-detachment block 1304 to move down. The anti-detachment block 1304 enters the placement slot of the placement box 12. Then, several limiting blocks 4 at the bottom of the sampler body 1 pass through several slots 1202 respectively, so that the insertion rod 3 and the limiting block 4 enter the cavity 1201. Rotate the sampler body 1 to drive the limiting block 4 to touch the baffle 14. At this time, the limiting blocks 4 are restricted in the vertical direction by the action of the top in the cavity 1201. At this time, the insertion hole 401 is aligned with the through hole on the placement box 12. After releasing the round block 1301, the elastic element 1303 resets and pulls the round block 1301 to move up, driving the insertion shaft 1302 and the anti-detachment block 1304 to insert into the insertion hole 401 to restrict the rotation of the limiting block 4, thereby completing the installation of the sampler body 1. When the sampler orientation needs to be adjusted, rotate the knurled knob 1005 to move the screw 1003 outward along the threaded hole 601 on the connecting box 6. The slide bar 1004 slides in the slide hole 602, and the screw 1003 moves the arc block 1001 away from the rotating block 9, so that the rubber friction plate 1002 disengages from the contact groove 901. The rotating block 9 can rotate freely with the bearing 8, thus adjusting the orientation of the sampler body 1. After adjustment, rotate the knurled knob 1005 in the opposite direction. The screw 1003 moves the arc block 1001 closer to the rotating block 9, and the friction plate 1002 tightly contacts the contact groove 901. The friction force restricts the rotation of the rotating block 9, thereby fixing the orientation of the sampler body 1.
