Description

Technical Field

[0001] The present invention relates to the technical field of testing devices, and in particular to a dust particle counter testing device. Background Art

[0002] A dust particle counter is an instrument used to measure the number and particle size distribution of dust particles per unit volume in a clean environment. It is mainly used in areas with high requirements for cleanliness and standard areas. It can monitor dust particles in the air. In order to ensure the accuracy of the monitoring data of the dust particle counter, it is necessary to regularly test and calibrate the dust particle counter through a testing device. Specifically, a particle suspension of standard specifications is atomized and sprayed out through a particle generator, and then the particle jet emitted is monitored by the dust particle counter. The monitoring data of the dust particle counter is used to determine whether it is standard.

[0003] However, as for the currently available particle generator for detecting dust particle counters, although the bottom is provided with moving wheels for convenient movement and transfer, the locking structures between the moving wheels are independent of each other, that is, when it is necessary to move, the moving wheels need to be unlocked one by one before they can be moved, and after the movement is completed, the moving wheels need to be locked again one by one, which is cumbersome and troublesome to use, and there is no protective structure when moving. When pushing the particle generator through uphill and downhill positions, if the moving wheels accidentally slip out of the hand, they cannot automatically stop, which can easily cause the particle generator to lose control, fall and be damaged, etc., and the flexibility and stability are poor, and the practicality is not high. Summary of the invention

When the control rod is not pushed or pulled manually, the four groups of moving mechanisms can automatically lock to ensure that the frame assembly and the particle generator are in a stable parked state. This design also ensures that when the particle generator moves through uphill and downhill positions, if the control action of the control rod is accidentally lost, the frame assembly can automatically stop and will not continue to move. The use is stable, the movement is convenient, and the flexibility, stability and practicality are extremely strong.

[0027] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Please refer to Figures 1 to 8 As shown: Embodiment 1: The present invention provides a dust particle counter inspection device, including a frame assembly, the frame assembly is composed of a supporting mechanism 2 and a moving mechanism 3; The support mechanism 2 includes a support frame 201 and a control rod 202. The rod body of the control rod 202 is "U"-shaped, and two side rods of the control rod 202 are inserted into the inside of the support frame 201. The particle generator 1 is fixedly installed on the top of the support frame 201. There are four groups of moving mechanisms 3, and the four groups of moving mechanisms 3 are respectively arranged inside the four vertical legs of the support frame 201. The moving mechanism 3 includes a moving wheel 301, a locking block 302 and a linkage rod 303. The moving wheel 301 is rotatably connected to the side of the bottom of the leg of the support frame 201, and the locking block 302 is axially inserted into the inside of the leg of the support frame 201 along the moving wheel 301, and the linkage rod 303 is longitudinally inserted into the inside of the leg of the support frame 201.

[0029] When the cam 302 is in the locked state, the locking cam 3032 is in the locked state, and the locking cam 3033 is in the locked state when the cam 302 is in the locked state. The locking block 302 is provided with a parking tooth block 3022 at one end thereof facing the moving wheel 301, and a parking tooth groove 3011 is provided inside the wheel axle of the moving wheel 301. When the linkage rod 303 is not pulled, the parking tooth block 3022 is inserted into the parking tooth groove 3011, so that the parking tooth block 3022 is inserted into the parking tooth groove 3011. The block cross section of the locking block 302 is a regular polygon, and a positioning groove is provided inside the leg of the support frame 201. 2011, the locking block 302 with a regular polygonal cross-section is inserted into the interior of the positioning groove 2011. Under the limiting effect of the positioning groove 2011, the locking block 302 cannot rotate inside the support frame 201, so that the parking tooth block 3022 of the locking block 302 can synchronously lock the moving wheel 301 through the parking tooth groove 3011, avoiding the phenomenon that the frame assembly and the particle generator 1 are changed in the use position due to accidental rotation, and the stability is extremely strong.

[0030] In the embodiment of the present disclosure, a locking rod 3032 is provided at the bottom of the linkage rod 303, and a locking groove 3021 is provided inside the locking block 302. The groove body of the locking groove 3021 is designed to be inclined, and the locking rod 3032 is inserted into the locking groove 3021. When the particle generator 1 needs to be changed in use or moved, it is only necessary to push or pull the control rod 202 in the corresponding direction. After the control rod 202 is manually operated, the four groups of movement can be automatically and synchronously released. The locking and parking state of the driving mechanism 3 is convenient to use. A lifting rod 3033 is provided on the top of the linkage rod 303, and a lifting groove 2021 is provided inside the side rod of the control rod 202, and the lifting rod 3033 is inserted into the lifting groove 2021. When the control rod 202 is pushed or pulled, the lifting groove 2021 can drive the linkage rod 303 to move upward and compress the parking top spring 3031 through the lifting rod 3033. When the control rod 202 moves upward, the locking control rod 3032 can pass through the locking control groove 3021 The locking block 302 is driven to move laterally inside the positioning groove 2011, so that the parking tooth block 3022 is disengaged from the parking tooth groove 3011, thereby releasing the locking state of the moving wheel 301. Thereafter, continuing to apply pushing or pulling force can drive the frame assembly and the particle generator 1 to move. When the moving action is completed and the manual control force of the control rod 202 is released, the frame assembly can automatically reset and restore the locked parking state of all the moving wheels 301 under the action of the parking top spring 3031. The operation is convenient, the operation process is simplified, and the flexibility is extremely strong. The design that the control force needs to be manually applied to the control rod 202 when moving the frame assembly makes it necessary to manually apply control force to the control rod 202 during the movement of the frame assembly. If the control force of the control rod 202 is accidentally lost in the uphill or downhill position, under the action of the parking top spring 3031, the four moving wheels 301 will trigger the locking state in time, avoiding the frame assembly and the particle generator 1 from losing control in the uphill or downhill position, thereby further improving the stability of the device.

[0031] In the disclosed embodiment, the groove body of the lifting groove 2021 is designed to be "V" shaped, and when the control rod 202 is not pushed or pulled by external force, under the action of the parking top spring 3031, the lifting rod 3033 is located at the lowest position in the middle of the groove body of the lifting groove 2021. This design ensures that no matter whether the control rod 202 is pushed or pulled, the lifting groove 2021 can always drive the linkage rod 303 to move upward through the lifting rod 3033 when the control rod 202 moves, thereby releasing the locked parking state of the moving wheels 301 of the four groups of moving mechanisms 3. It is easy to use, and when a pushing force is applied to the control rod 202, the frame assembly can move in the direction facing the operator, and when a pulling force is applied to the control rod 202, the frame assembly can move in the direction facing the operator.

[0032] Specific usage and function of this embodiment: In the present invention, the particle generator 1 is used to detect, calibrate and demarcate the dust particle counter, and when the control rod 202 is not pushed or pulled manually, the frame assembly will be in a parked state for use, and the particle generator 1 can be stably kept in the current position for use. At this time, the moving wheels 301 of the four groups of moving mechanisms 3 are all in a locked state, and the frame assembly will not accidentally move to change the use position of the particle generator 1. The use is stable. When the control rod 202 is not pushed or pulled manually, under the action of the parking top spring 3031, the lifting rod 3033 is in the lowest position of the lifting groove 2021, and the locking rod 3032 locates the use position of the locking block 302 through the locking groove 3021. The parking tooth block 3022 is inserted into the parking tooth groove 3011. Under the limiting effect of the positioning groove 2011, the locking block 302 cannot rotate inside the support frame 201, so that the parking tooth block 3022 of the locking block 302 can synchronously lock the moving wheel 301 through the parking tooth groove 3011 to prevent the accidental rotation of the locking tooth block 3022 from causing the frame assembly and the particle generator 1 to change their use position. When it is necessary to move the particle generator 1 or change the use position of the particle generator 1, it is only necessary to push or pull the control rod 202 in the corresponding direction. After the control rod 202 is manually operated, it can automatically and synchronously release the locked parking state of the four groups of moving mechanisms 3, which is easy to use. When the control rod 202 is pushed and pulled, the lifting groove 2021 can The lifting rod 3033 drives the linkage rod 303 to move upward and compress the parking top spring 3031. When the control rod 202 moves upward, the locking rod 3032 can drive the locking block 302 to move horizontally inside the positioning groove 2011 through the locking groove 3021, so that the parking tooth block 3022 escapes from the parking tooth groove 3011, thereby releasing the locking state of the moving wheel 301. Thereafter, continuing to apply pushing or pulling force can drive the frame assembly and the particle generator 1 to move. When the moving action is completed and the human control force on the control rod 202 is released, the frame assembly can automatically reset and restore the locked parking state of all the moving wheels 301 under the action of the parking top spring 3031. The design of the lifting groove 2021 as a "V"-shaped groove body makes The lifting groove 2021 can always drive the linkage rod 303 to move upward through the lifting rod 3033 when the control rod 202 moves, so as to release the locking parking state of the moving wheels 301 of the four groups of moving mechanisms 3. It is convenient to use, and when the control rod 202 is pushed, the frame assembly can move in the direction the operator is facing, and when the control rod 202 is pulled, the frame assembly can move in the direction the operator is facing. The design that the control force needs to be applied to the control rod 202 manually when moving the frame assembly makes it possible for the frame assembly to lose the control force of the control rod 202 accidentally when it is in the uphill or downhill position during the movement of the frame assembly. Under the action of the parking top spring 3031,The four moving wheels 301 will trigger the locking state in time to prevent the frame assembly and the particle generator 1 from losing control in uphill and downhill positions.

[0033] In another embodiment, a track block 2022 with a "T"-shaped cross-section is provided on the outside of the side rod of the control rod 202, and a track groove 2012 is provided on the inside of the support frame 201, and the track block 2022 is inserted into the inside of the track groove 2012. The track block 2022 can limit the moving trajectory and the maximum moving distance of the control rod 202 when pushing and pulling through the track groove 2012, so that the control rod 202 will not be skewed or twisted when manually controlled, thereby further improving the stability of the device.
