Description

Technical Field

[0001] This utility model belongs to the technical field of air sampling equipment, and in particular relates to a mobile device for sampling. Background Technology

[0002] Factory workshops are places where products are manufactured. Since the main pollutants in the workshops are generated by different production processes, and different production processes produce different pollutants, in order to ensure the safety of the workplace and the health of the workers, it is necessary to use sampling devices to sample the air in each workshop of the factory and then bring the samples back to the laboratory for testing.

[0003] Publication No. CN219532607U discloses an air sampling mechanism for a factory workshop. When adjusting the sampling height using a height adjustment unit, a servo motor is activated to rotate a lead screw. Two sliders slide in the second sleeve slide rail, limiting the support rod and causing it to slide up and down inside the second sleeve. This causes the air inlet box to move the air inlet pipe up and down inside the first sleeve, thereby adjusting the sampling height of the air inlet box and enabling the sampling of air at different heights in the workshop.

[0004] The aforementioned existing technologies still have the following drawbacks in practical implementation:

[0005] During the use of the device, when sampling air from different workshops, staff need to push the device to move it. Due to the large size and weight of the device, staff need to apply additional force to move it, which increases the workload of staff and makes the device less flexible and convenient. In addition, the device is prone to displacement due to external impacts during air sampling, resulting in poor stability.

[0006] To address the above issues, we propose a mobile sampling device. Utility Model Content

[0009] The locking mechanism includes a vertical plate, a lead screw, an L-shaped support plate, a movable plate, an arc-shaped block, and a locking block. The two vertical plates are fixedly fixed to the bottom of the base. The lead screw is rotatably disposed between the two vertical plates. The two L-shaped support plates are threaded onto the lead screw. The ends of the two L-shaped support plates that are far apart from each other are fixedly connected to the movable plate. The two arc-shaped blocks are fixedly disposed on the side of the movable plate that is far away from the L-shaped support plates. The locking block is fixed in the arc-shaped concave surface of the arc-shaped block, and the locking block and the locking groove cooperate with each other.

[0010] A guide rod is provided on the lower side of the lead screw. The guide rod passes through the L-shaped support plate, and the L-shaped support plate and the guide rod are slidably engaged. The thread directions of the two threaded holes inside the L-shaped support plate are opposite.

[0011] A crank is provided on the lower side of the base, and the crank is connected to the left end of the lead screw. Two movable handles are provided opposite each other on the left side surface of the sampling mechanism body.

[0012] An L-shaped bracket is fixed to the bottom right side of the base. A servo motor is installed inside the L-shaped bracket. The output end of the servo motor is connected to the active bevel gear. A non-locking switch is provided on the handle part of the moving handle near the front side. The non-locking switch is electrically connected to the servo motor.

[0013] The sampling mechanism includes a mechanism box, with an air intake fan and a first sleeve mounted on the top of the mechanism box.

A height adjustment part is connected between the bottom of the air inlet box and the mechanism box. A vacuum pump is installed on one side of the mechanism box.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model facilitates the sampling of workshop air through its sampling mechanism. The meshing of the driving bevel gear and the driven bevel gear, combined with the rotational engagement of the rotating rod and the fixed plate, facilitates the rotation of the rotating rod on the right side. In conjunction with the rollers and the rotating rod on the left side, the entire device can be moved without the need for staff to push it forward, saving manpower. This solves the problems of existing technologies that require staff to push the device when sampling air from different workshops. Due to the large size and weight of the device, staff need to apply additional force to move it, increasing their workload and resulting in poor flexibility and convenience.

[0016] Meanwhile, the locking mechanism and the slot work together to limit and lock the rotating rod, further ensuring the stability of the bottom of the sampling mechanism body.

[0023] This specific embodiment is a mobile device for sampling, such as... Figures 1-5 As shown, the mobile device for sampling includes a base 1, a sampling mechanism body 2 is set on the top of the base 1, several fixed plates 3 are fixedly fixed at the bottom of the base 1, a rotating rod 4 is rotatably set between two adjacent fixed plates 3, the end of the rotating rod 4 passes through the fixed plate 3 and is connected to a roller 5, a driven bevel gear 6 is set on the right side of the rotating rod 4, a driving bevel gear 7 is meshed on the upper side of the driven bevel gear 6, several slots 13 are opened on the outer wall of the rotating rod 4, and a locking mechanism is set on the lower side of the base 1, which cooperates with the slots 13 on the rotating rod 4.

[0024] The sampling mechanism body 2 facilitates the sampling of workshop air. The meshing of the driving bevel gear 7 and the driven bevel gear 6, combined with the rotational engagement of the rotating rod 4 and the fixed plate 3, facilitates the rotation of the right-side rotating rod 4. With the help of the roller 5 and the left-side rotating rod 4, the entire device can be moved without the need for staff to push it forward, saving manpower. This solves the problem of existing technologies that require staff to push the device when sampling air from different workshops. Due to the large size and weight of the device, staff need to apply additional force to move it, increasing their workload and reducing the device's flexibility and convenience. At the same time, the locking mechanism and the slot 13 work together to limit and lock the rotating rod 4, further ensuring the stability of the bottom of the sampling mechanism body 2. This solves the problem of existing technologies where the device is prone to displacement and poor stability when subjected to external impacts during air sampling.

[0025] The locking mechanism includes a vertical plate 8, a lead screw 9, an L-shaped support plate 10, a movable plate 11, an arc-shaped block 12, and a locking block 14. The two vertical plates 8 are fixed to the bottom of the base 1. The lead screw 9 is rotatably disposed between the two vertical plates 8. The two L-shaped support plates 10 are threaded onto the lead screw 9. The ends of the two L-shaped support plates 10 that are far apart from each other are fixedly connected to the movable plate 11. The two arc-shaped blocks 12 are fixed to the side of the movable plate 11 that is far away from the L-shaped support plates 10. The locking block 14 is fixed in the arc-shaped concave surface of the arc-shaped block 12, and the locking block 14 cooperates with the locking groove 13.

[0026] A guide rod 15 is provided on the lower side of the lead screw 9. The guide rod 15 passes through the L support plate 10, and the L support plate 10 and the guide rod 15 are in sliding fit. The thread directions of the internal threaded holes of the two L support plates 10 are opposite.

[0027] A crank handle 16 is provided on the lower side of the base 1. The crank handle 16 is connected to the left end of the lead screw 9. Two movable handles 19 are provided opposite each other on the left side surface of the sampling mechanism body 2.

[0028] An L-bracket 18 is fixed to the bottom right side of the base 1. A servo motor 17 is installed inside the L-bracket 18. The output end of the servo motor 17 is connected to the active bevel gear 7. A non-locking switch is provided on the handle part of the front moving handle 19. The non-locking switch is electrically connected to the servo motor 17.

[0029] The sampling mechanism body 2 includes a mechanism box, with an air intake fan and a first sleeve installed on the top of the mechanism box. A rigid pipe is connected to one side of the air intake fan, extending into the interior of the mechanism box and connecting to a sample collection part. The air intake fan and the first sleeve are connected by a flexible hose. An air inlet pipe slides up and down inside the first sleeve, with one end of the air inlet pipe connected to an air inlet box. A height adjustment part is connected between the bottom of the air inlet box and the mechanism box. A vacuum pump is installed on one side of the mechanism box.

[0030] Example:

[0031] When in use, when the operator holds the handle of the moving handle 19, pressure is applied to the non-locking switch to energize it, which in turn energizes the servo motor 17. The servo motor 17 drives the active bevel gear 7 to rotate. Under the meshing action of the active bevel gear 7 and the driven bevel gear 6, the rotating rod 4 on the right side is driven to rotate. Together with the rotating rod 4 on the left side and the roller 5, the device is driven forward. There is no need for the operator to push the device to move it, which saves manpower and solves the drawback of the existing technology when sampling air from different workshops. The operator needs to push the device to move it because the device is large in size and has a certain weight. The operator needs to apply additional force to the device to move it, which increases the workload of the operator.

[0032] After the device is moved to the appropriate position, the non-locking switch is released, the servo motor 17 is de-energized, the device stops moving, and at the same time the rocker arm 16 is turned, which drives the lead screw 9 to rotate. With the threaded engagement between the L support plate 10 and the lead screw 9, and the sliding engagement between the L support plate 10 and the guide rod 15, the two L support plates 10 are driven to move away from each other stably, which in turn drives the arc block 12 to move closer to the corresponding rotating rod 4 until the arc block 12 and the rotating rod 4 are pressed together, and the locking block 14 is driven to insert into the corresponding slot 13, so as to achieve the purpose of limiting and locking the two rotating rods 4, and further limiting and fixing the bottom of the device to ensure the stability of the bottom of the device.

[0033] The slot 13 is provided with multiple slots, and the size of the card block 14 is small, which makes it easy to drive the card block 14 into the corresponding slot 13 when the arc block 12 is adjusted to approach the rotating rod 4.

[0034] Finally, the air in the workshop is sampled and collected by the sampling mechanism 2.

[0035] Compared with the prior art, this utility model uses the cooperation of servo motor 17, active bevel gear 7 and driven bevel gear 6 to drive the rotating rod 4 on the right side to rotate. With the help of the roller 5 on the right side, the device is actively driven to move forward, reducing the burden on the operator to push the device forward. At the same time, the combined action of crank handle 16, lead screw 9 and L support plate 10 drives the arc block 12 to approach and fit against the outer wall of the rotating rod 4, and drives the locking block 14 to insert into the corresponding slot 13 to limit and lock the rotating rod 4. This further achieves the purpose of limiting and fixing the bottom of the device, avoiding the phenomenon of movement due to external collisions during air sampling, and ensuring the overall stability of the device.

[0036] It should be further noted that the installation structure, connection method or setting method of each component in this utility model are all common mechanical methods. As long as they can achieve their beneficial effects, they can be implemented. At the same time, the servo motor 17 in this utility model is purchased from the market. Those skilled in the art can install and use it according to the requirements.

[0038] All technical features in this embodiment can be freely combined according to actual needs.
