Description

Technical Field

[0001] This utility model relates to the field of information acquisition technology, and in particular to an external device for information acquisition equipment. Background Technology

[0002] Information collection equipment, especially portable instruments such as handheld collectors, are widely used in various situations requiring real-time monitoring of specific environmental parameters, such as industrial safety production, environmental protection, and emergency rescue, due to their small size and flexible operation. The original design purpose of these devices is to facilitate mobile and immediate inspections by staff.

[0003] However, in practical applications, there are often scenarios where long-term, continuous fixed-point monitoring of a specific area or potential risk point is required. In this working mode, the original portability advantage of handheld devices becomes a limitation of their application. Operators must hold the device for a long time and keep it in a fixed position, which not only greatly increases the labor intensity and easily leads to fatigue, but also makes it difficult to ensure the long-term stability of the device's acquisition probe due to human shaking, which may affect the continuity and stability of the monitoring data.

[0004] More importantly, many industrial sites or outdoor environments contain large amounts of dust, suspended particulate matter, or aerosols. When handheld data collectors operate directly in such environments, these airborne impurities are drawn into the device's detection port along with the airflow. Once these particles enter the device, they may adhere to the sensor surface, affecting the sensor's sensitivity and response speed, leading to deviations in detection results. In severe cases, they may cause blockage or permanent damage to the sensor's air path, significantly shortening the device's lifespan and increasing maintenance costs and the risk of device failure.

[0005] Therefore, this utility model proposes an external device for information acquisition equipment to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of inconvenience, poor stability, and limited functionality of existing technologies, such as the inability to fix the device for long-term handheld monitoring, and the susceptibility of detection accuracy to interference from dust particles in the environment, this utility model aims to provide a structured improvement that can effectively solve the above problems.

[0007] This utility model provides an external device for an information acquisition equipment, including a support mechanism for the acquisition device and a filter mechanism detachably installed at the detection port of the acquisition device. The support mechanism includes a base, a clamping component disposed on the base for elastically holding the acquisition device, and a telescopic bracket connected to the bottom of the base; the filter mechanism includes a filter, a sealing ring provided inside the filter, and a USB interface for powering its internal functional modules.

[0008] Preferably, the clamping assembly includes two clamping blocks disposed opposite each other on the base, a stop plate disposed on the base and positioned to cooperate with the clamping blocks, a connecting ring for transmitting force, and a spring for providing a restoring force.

[0009] Preferably, the spring is sleeved on the outer wall of the connecting ring, and the connecting ring drives the two clamping blocks to move towards each other under the elastic force of the spring.

[0010] Preferably, the clamping block is provided with a rubber pad on the inner wall facing the collector.

[0011] Preferably, the support mechanism further includes straps for restraining or binding the telescopic support.

[0012] Preferably, the telescopic support is a tripod structure composed of multiple relatively telescopic rods.

[0013] Preferably, the filtering mechanism also includes a connecting cable for connecting the USB interface to the collector or an external power supply.

[0014] Preferably, the sealing ring is disposed on the inner wall of the filter and is used to fit tightly against the edge of the detection port of the collector after installation.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model solves the problems of labor costs, fatigue, and difficulty in maintaining stable equipment position and posture caused by the need for manual handling during long-term continuous monitoring in the prior art by setting up a support mechanism composed of a base, elastic clamping components, and a telescopic bracket. It achieves the beneficial effect of fixing the equipment stably and reliably in the detection position, freeing the operator's hands, and facilitating unattended long-term continuous monitoring.

[0017] 2. This utility model solves the problem in the prior art where the equipment is directly exposed to a dusty environment, and suspended particulate matter in the air easily enters the detection port, thus interfering with the accuracy of the detection data and potentially damaging the internal sensors. It achieves the beneficial effect of effectively pre-filtering the sampled gas, ensuring the accuracy and reliability of the detection results, while protecting the core components inside the equipment and extending its service life.

[0018] 3. This utility model solves the problem that existing auxiliary devices have limited functions and cannot simultaneously meet the requirements of stable fixation and sample purification by integrating a support mechanism with a filtration mechanism with a sample purification function. This achieves the beneficial effect of making the entire external device compact, functionally comprehensive and easy to use, and greatly improves the applicability and working efficiency of the collector in complex field environments.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Example:

[0027] Please refer to Figures 1 to 4 This utility model provides an external device for an information acquisition device, which aims to solve the problems in the prior art where the acquisition device 1 is inconvenient to hold and fix for a long time and is easily affected by dust particles in the environment, thus affecting the detection accuracy.

[0028] like Figure 1As shown, the external device for the data collector 1 includes a support mechanism 2 and a filter mechanism 3. The support mechanism 2 and the filter mechanism 3 cooperate with each other to act on the data collector 1 to be tested. The main body of the support mechanism 2 is the base 201, which provides a stable support platform and clamping fixation for the data collector 1. The filter mechanism 3, as a front-end pretreatment module, is detachably installed at the detection port of the data collector 1 to purify the sampled gas. Together, they ensure that the data collector 1 can perform long-term, high-precision unattended testing. Specifically, the basic frame of the device is composed of the support mechanism 2, as shown in the figure. Figure 1 and Figure 4 The support mechanism 2 includes a base 201 and a telescopic bracket 202 connected to the bottom of the base 201. The telescopic bracket 202 is a tripod structure composed of multiple relatively telescopic rods, which is used to stably support the base 201 on the working surface. At the same time, a clamping component for clamping the collector 1 is also integrated on the base 201.

[0029] The specific structure of this clamping assembly, which is the core technology of this embodiment, is crucial for effectively securing the collector 1. Please refer to the following for details. Figure 1 and Figure 3 The clamping assembly includes two clamping blocks 204 disposed opposite each other on the base 201, a stop plate 205 disposed on the base 201 and positioned to cooperate with the clamping blocks 204, a connecting ring 206 for transmitting force, and a spring 207 for providing a restoring elastic force. The stop plate 205 abuts against the rear end of the collector 1 to provide axial positioning for the device. Rubber pads 208 are fixedly connected to the inner sidewalls of the two clamping blocks 204 facing the collector 1 by adhesive or embedding. To achieve elastic clamping, the spring 207 is sleeved on... The outer wall of the connecting ring 206 serves as a transmission component. One end of the connecting ring 206 is fixedly connected to the clamping block 204, and the other end is fixedly connected to the side end of the abutment plate 205. When the clamping block 204 is pulled outward, the connecting ring 206 is driven and the spring 207 is deformed to store energy. After release, the elastic force released by the spring 207 drives the two clamping blocks 204 to move towards each other through the connecting ring 206. The rubber pad 208 then tightly adheres to and clamps the collector 1. This structure not only ensures stable and reliable clamping action, but also effectively prevents slippage and protects the surface of the equipment.

[0030] Based on the above embodiments, the present invention may further include the following preferred technical solutions, as described above. Figure 4To enhance the overall stability and ease of use, the telescopic support 202 is preferably a tripod structure composed of multiple relatively telescopic rods. When unfolded, it forms a stable three-point support to adapt to different working surfaces. The support mechanism 2 also includes a strap 203, which passes between the rods of the telescopic support 202 or wraps directly around its exterior. This strap is used to restrain or bind the telescopic support 202 in its retracted state, preventing it from accidentally coming apart. As another key technical component, please refer to... Figure 2 The filtration mechanism 3 includes a filter 301 as the main body. One end of the filter 301 is open for fitting onto the detection port of the collector 1. To ensure airtightness, a sealing ring 304 is arranged around the inner wall of the filter 301. After installation, it relies on its elastic deformation to tightly fit the edge of the detection port of the collector 1, thereby preventing unfiltered air from entering through the connection gap. To ensure the filtration effect, the filter 301 is also equipped with a USB interface 302, which is electrically connected to the collector 1 or an external power source through a connecting cable 303, providing working power to the internal functional modules inside the filter 301.

[0031] Working principle: When the data collector 1 needs continuous detection, it can be supported by the support mechanism 2. First, the clamping blocks 204 on the left and right sides of the base 201 are expanded by hand. At this time, the connecting rings 206 at the left and right ends of the abutment plate 205 are driven by the two clamping blocks 204. Then, the connecting rings 206 drive the springs 207 on the outer wall. Then, the data collector 1 is placed on the top of the base 201. At this time, the abutment plate 205 abuts against the rear end of the data collector 1. Then, the clamping blocks 204 are released. At this time, the springs 207 drive the connecting rings 206 to move forward. The device is then retrieved, and the connecting ring 206 drives the front clamping block 204. The rubber pad 208 on the outer wall of the clamping block 204 contacts the left and right ends of the collector 1. The clamping block 204 then fixes the collector 1 to prevent it from deviating from its position. Next, the telescopic bracket 202 at the bottom of the base 201 is operated. When needed, the length of the telescopic bracket 202 can be adjusted through the telescopic adjustment structure. At this time, the strap 203 at the bottom of the base 201 opens along with the telescopic bracket 202 to stabilize the telescopic bracket 202. There is no need to hold the collector 1 for continuous detection.

[0032] Before the collector 1 starts the detection program, the filter mechanism 3 is installed to prevent dust in the air from entering directly. First, the filter 301 is installed at the detection port at the top of the collector 1. Then, the connecting wire 303 at the rear of the filter 301 is connected to the USB interface 302 at the top of the filter 301 to supply power to the filter 301. After that, the sealing ring 304 on the inner wall of the filter 301 fits against the edge of the detection port of the collector 1, completely blocking unfiltered air from entering through the gap, so that dust in the air cannot enter the collector 1 and affect the detection results.
