Description

Technical Field

[0001] This utility model relates to the field of dust sampler technology, specifically to a rotating support type dust sampler. Background Technology

[0002] A dust sampler is a portable device used to collect dust samples from dusty air. Measuring the concentration of dust in the air is necessary not only for safety management but also to provide a scientific basis for researching dust prevention, reduction, and removal measures. Using a sampler to measure dust is a widely recognized method with high accuracy. It is widely used in disease prevention, environmental monitoring, occupational safety, work safety supervision, military, scientific research and teaching, metallurgy, petrochemicals, railways, building materials, and other sectors for hygiene monitoring and evaluation, and is specifically used to determine the average dust concentration in the air within production work areas.

[0003] Traditional dust samplers typically use fixed supports, which means they can only sample dust from a fixed direction. In practical applications, dust distribution is often complex and varied, not only existing in a single direction but also coming from multiple directions. Therefore, the fixed support design greatly limits the sampling range of the dust sampler, making it impossible to comprehensively and effectively sample dust from multiple directions. Utility Model Content

[0004] The purpose of this invention is to provide a rotating bracket-type dust sampler to solve the problem mentioned in the background art that traditional dust samplers usually use fixed brackets, which means that the dust sampler can only sample dust in a fixed direction. In practical applications, the distribution of dust is often complex and variable, and may not only exist in a single direction, but may also come from multiple directions. Therefore, the fixed bracket design greatly limits the sampling range of the dust sampler, making it impossible to comprehensively and effectively sample dust from multiple directions.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rotating support dust sampler includes a fixed cylinder, a base frame is circumferentially provided on the bottom outer surface of the fixed cylinder, and a fixed cone is provided at each end of the base frame away from the fixed cylinder. A lifting column is movably installed inside the fixed cylinder, and a bracket is fixedly connected to the top of the lifting column through a bearing. The dust sampler body is detachably connected to the top of the bracket, and a rotating mechanism is provided on the top outer surface of the fixed cylinder.

[0007] Optionally, the bottom of the dust sampler body is symmetrically provided with grooves that cooperate with the side plate of the bracket, and rubber blocks are fixed at the four corners of the dust sampler body.

[0008] Optionally, the rotating mechanism includes an annular groove formed on the outer surface of the top of the fixed cylinder, with a plurality of balls arranged in the annular groove, and a mounting sleeve movably fitted around the outside of the fixed cylinder at the annular groove. The mounting sleeve has a plurality of insertion holes on its outer ring, and corresponding rocker arms are inserted into the insertion holes.

[0009] Optionally, the inner side of the mounting sleeve is provided with an annular ring, and the annular ring is rotatably disposed within the annular groove.

[0010] Optionally, the upper surface of the mounting sleeve is provided with an adaptive rod that is fixedly connected to the bottom of the bracket.

[0011] Optionally, the outer surface of the lifting column is provided with a clamping groove along the column body direction.

[0012] Optionally, the upper outer surface of the fixed cylinder is provided with a knob cap, and the side of the knob cap is provided with a clamping rod that cooperates with the clamping groove.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of a rotating mechanism, uses the cooperation of ball bearings and annular rings to pull the rocker arm, thereby driving the mounting sleeve to rotate. Then, through the setting of an adaptive rod, the rotation of the mounting sleeve is transmitted to the bracket, which in turn drives the dust sampler body to rotate, realizing all-round sensing and sampling of dust, ensuring the comprehensiveness of the sampling results, and avoiding errors in the sampling process. At the same time, by rotating the knob cap, the clamping rod applies stress to the clamping groove, thereby clamping and fixing the clamping groove, ensuring the stability of the lifting column after adjustment.

[0015] 2. This utility model adopts a detachable connection between the dust sampler body and the bracket, which makes it convenient for users to replace different models of sampler bodies according to actual needs. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] The preferred embodiment of the present invention will be described below.

[0025] Please see Figure 1-5 As shown, the rotating support dust sampler includes a fixed cylinder 1, a base frame 2 is provided around the bottom outer surface of the fixed cylinder 1, and a fixed cone 9 is provided at the end of the base frame 2 away from the fixed cylinder 1. A lifting column 3 is movably installed inside the fixed cylinder 1. A bracket 4 is fixedly connected to the top of the lifting column 3 through a bearing. The dust sampler body 5 is detachably connected to the top of the bracket 4. A rotating mechanism 6 is provided on the top outer surface of the fixed cylinder 1.

[0026] Furthermore, the bottom of the dust sampler body 5 is symmetrically provided with wire grooves 501 that cooperate with the side plate of the bracket 4, and rubber blocks 502 are fixed at the four corners of the dust sampler body 5. The rubber blocks 502 provide additional protection and fixation, and the user can easily pull the dust sampler body 5 off the bracket 4 and replace it with a different model of sampler body according to actual needs.

[0027] Furthermore, the outer surface of the lifting column 3 is provided with a clamping groove 301 along the column body direction, and the upper outer surface of the fixed cylinder 1 is provided with a knob cap 8. The side of the knob cap 8 is provided with a clamping rod 801 that cooperates with the clamping groove 301. After the lifting column 3 has completed its upward or downward movement, the user rotates the knob cap 8 to make the clamping rod 801 apply stress to the clamping groove 301, thereby clamping and fixing the lifting column 3.

[0028] In another embodiment provided by this utility model, such as Figure 3 , 4As shown in Figure 5, the rotating mechanism 6 includes an annular groove 601 formed on the outer surface of the top of the fixed cylinder 1. A plurality of balls 602 are arranged in the inner ring of the annular groove 601. An mounting sleeve 603 is movably fitted on the outside of the fixed cylinder 1 about the annular groove 601. The annular groove 601 provides a circular track for the balls 602, allowing the balls 602 to roll smoothly in it. A plurality of insertion holes 605 are arranged in the outer ring of the mounting sleeve 603. A corresponding rocker arm 606 is inserted into the insertion hole 605. The rotation of the mounting sleeve 603 is driven by shaking the rocker arm 606.

[0029] Furthermore, an annular ring 604 is provided on the inner side of the mounting sleeve 603, and the annular ring 604 is rotatably disposed in the annular groove 601. The rotational power is transmitted to the mounting sleeve 603 through the annular ring 604, so that the mounting sleeve 603 can rotate around the fixed cylinder 1 while maintaining a certain stability and smoothness.

[0030] Furthermore, the upper surface of the mounting sleeve 603 is provided with an adaptive rod 7 that is fixedly connected to the bottom of the bracket 4. The rotation of the mounting sleeve 603 is transmitted to the bracket 4 through the adaptive rod 7. The adaptive rod 7 adaptively adjusts its own length in accordance with the rising or falling movement of the lifting column 3.

[0031] Specifically, when the user needs to adjust the direction of the dust sampler body 5, this can be achieved by shaking the rocker arm 606. The rocker arm 606 is inserted into the socket 605 on the outside of the mounting sleeve 603. By shaking the rocker arm 606, the user can rotate the mounting sleeve 603 around the fixed cylinder 1. Due to the rolling engagement of the ball bearings 602 between the mounting sleeve 603 and the annular groove 601, this rotation is smooth and stable. When the mounting sleeve 603 rotates, the adaptive rod 7 will rotate accordingly and transmit this rotation to the bracket 4. The bracket 4 then transmits the rotation to the dust sampler body 5 through the connecting structure at its top. Therefore, by shaking the rocker arm 606, the user can indirectly control the rotation direction of the dust sampler body 5, achieving omnidirectional sensing and sampling of dust.

[0032] In use, the device is fixed to the ground by the fixing cone 9, and then the height of the lifting column 3 is adjusted by pulling the bracket 4 so that the dust sampler body 5 reaches the appropriate sampling position. At the same time, the adaptive rod 7 adjusts its own length accordingly as the lifting column 3 rises or falls. When the lifting column 3 reaches the required height, the knob cap 8 is rotated so that the side clamping rod 801 applies stress to the clamping groove 301 on the outer surface of the lifting column 3, thereby fixing the position of the lifting column 3 and preventing it from moving. Then, by shaking the rocker arm 606, the mounting sleeve 603 can be rotated around the fixing cylinder 1. As the mounting sleeve 603 rotates, the inner annular ring 604 rolls in the annular groove 601 to ensure the smoothness and stability of the rotation.

[0033] At the same time, the adaptive rod 7 on the mounting sleeve 603 will rotate accordingly, and transmit the rotation to the bracket 4 through the fixed connection with the bracket 4. The bracket 4 then transmits the rotation to the dust sampler body 5 through the connection structure at its top. Continue to shake the rocker arm 606 until the dust sampler body 5 reaches the required sampling direction, realizing all-round sensing and sampling of dust, and ensuring the comprehensiveness of the sampling results.

[0034] In another embodiment provided by this utility model, such as Figure 6 As shown, the bottom of the fixed cone 9 can be snapped with a movable base 10, which allows the device to be used indoors after assembly.

[0035] When used outdoors, the device is fixed to the ground by the fixed cone 9. When used indoors, the fixed cone 9 on the whole machine is snapped into the mobile chassis 10 so that the two can be connected to form a whole, thus ensuring that it can be used indoors and increasing the sampling range.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
