Description

Technical Field

[0001] This utility model relates to the field of atmospheric detection, and in particular to a filter membrane clip storage device that facilitates the retrieval of filter membrane clips. Background Technology

[0002] Dust samplers are widely used in health monitoring and evaluation in departments such as disease prevention, environmental monitoring, labor protection, safety supervision, military, scientific research and teaching, metallurgy, petrochemicals, railways, and building materials. They are specifically used to determine the average concentration of dust in the air within the workplace of production teams.

[0003] Dust samplers typically use an air pump to draw air from the filter element, trapping dust on the outer filter membrane for sampling. After sampling, the filter membrane needs to be removed, secured with a filter membrane clamp, and then temporarily stored in a filter membrane storage box. Because the filter membrane storage box can shake and collide during transport, the collected particles on the filter membrane can fall off, affecting the sampling results. In existing technologies, such as the filter membrane clamp storage device for an automatic membrane changer disclosed in Chinese Patent Application No. 202223355029.0, several fixed clamps restrict the movement of the filter membrane clamps, preventing collisions between them. Spring clips further limit the shaking of the filter membrane clamps between the clamps, further limiting the fall of particles caused by the clamps' own shaking and collisions during transport within the filter membrane storage box.

[0004] However, although the spring clips can limit the shaking of the filter membrane clamp during the transport of the filter membrane storage box, the two spring clips each apply a spring force to the filter membrane clamp, causing a certain frictional resistance on both sides of the filter membrane clamp. When the filter membrane clamp separates from the position between the two spring clips along the direction perpendicular to the spring force, the filter membrane clamp needs to overcome the frictional resistance to separate from the position between the two spring clips. After separation, the filter membrane clamp also needs to decelerate. That is, if the two spring clips clamp the filter membrane clamp too tightly, it will cause the filter membrane clamp to vibrate violently for a moment. This may cause particles on the filter membrane to fall off and affect the final measurement results. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a filter membrane clip storage device that facilitates the removal of filter membrane clips. This solves the problem in existing technologies where, when a filter membrane clip is held in place by a spring clip, pulling it out causes a sudden, violent vibration, resulting in particles falling off the filter membrane and affecting the final measurement results. The new device allows the filter membrane clip to be smoothly removed without force, preventing particles from scattering due to sudden, violent vibration.

[0007] The filter membrane clip storage device provided by this utility model, which facilitates the retrieval of filter membrane clips, preferably includes two tension springs in the fastening assembly; the two ends of the tension springs are respectively connected to the top clamping plate and the bottom clamping plate; The extension of the clamping plate has a fastening hole extending through it in the vertical direction; the tension spring includes a spring body and two hooks; the two hooks respectively hook the fastening hole of the top clamping plate and the fastening hole of the bottom clamping plate.

[0008] The filter membrane clip storage device provided by this utility model, which facilitates the handling of filter membrane clips, preferably has elastic buffer protrusions on both the upper and lower surfaces of the clip plate.

[0009] The filter membrane clip storage device provided by this utility model, which facilitates the handling of filter membrane clips, preferably includes a limiting ring within the ball groove; the limiting ring is placed horizontally, with the direction closest to the center of the limiting ring as the inner side of the limiting ring, the upper edge of the limiting ring bending inward, and the lower edge of the limiting ring bending inward; the diameter of the ball is smaller than the maximum diameter of the inner circle of the annular cross-section of the limiting ring, and the diameter of the ball is larger than the minimum diameter of the inner circle of the annular cross-section of the limiting ring; the ball is slidably fitted within the limiting ring.

[0010] The filter membrane clip storage device provided by this utility model is easy to pick up and store. Preferably, the front side of the tray is provided with a handle.

[0011] The above technical solution has the following advantages or beneficial effects: The present invention provides a filter membrane clip storage device for easy handling of filter membrane clips, which includes a slide, several clamping plates, several trays and fastening components for stable storage of filter membrane clips; Specifically, the slide is groove-shaped, with its internal space used to accommodate the filter membrane clips. The slide is vertically positioned so that the filter membrane clips can be stacked horizontally within it, maintaining the filter membranes within the clips in a horizontal position. This prevents particles on the filter membranes from detaching due to tilting, improving the accuracy of particle measurement results. To facilitate explanation of the filter membrane clip storage device's structure, the groove of the slide faces forward. Slotted sliding holes are provided on both the left and right side walls of the slide to restrict the sliding direction of the clamping plates. Specifically, the extending direction of the sliding holes is the same as the extending direction of the slide, restricting the vertical movement of the clamping plates. The clamping plates are used to clamp the filter membrane clips, stably storing them. Here, the clamping plates are adjustable to maintain the tightness of the clamping. To allow the filter membrane clips to be stacked horizontally within the slide, the clamping plates are horizontally positioned and located within the slide. The gap between the two clamping plates is used to store the filter membrane clips. To enable the clamping plates to move under the restriction of the sliding holes, the left and right sides of the clamping plates... Extensions are provided on both sides, extending into the sliding hole. Furthermore, the edges of the clamping plates are aligned with the inner wall of the slide, and the edges of the extensions are aligned with the inner wall of the sliding hole, thus preventing the clamping plates from wobbling on the slide. This also prevents the clamping plates from moving due to friction when the filter membrane clamp is pulled out, thereby avoiding errors in the measurement results of particulate matter on the filter membrane caused by clamping plate wobbling. To achieve adjustable clamping force and maintain the clamping force on the filter membrane clamp, a fastening assembly applies clamping force to the top and bottom clamping plates. When one filter membrane clamp is removed, the fastening assembly automatically adjusts the position of the clamping plates and re-clamps the remaining filter membrane clamps. Furthermore, to prevent the filter membrane clamp from falling and vibrating due to the upward contraction of the bottom clamping plate, the bottom clamping plate is fixed to the slide, allowing only the top clamping plate to contract downwards and clamp. It should be noted that the "top clamping plate" and "bottom clamping plate" refer to the clamping plate at the highest and lowest positions, respectively. To facilitate easy removal of the filter membrane clip from between two adjacent clamping plates and prevent severe vibration caused by excessive clamping force applied to the top and bottom clamping plates by the fastening components during removal, a tray is placed between the two adjacent clamping plates. The tray is plate-shaped and placed horizontally, with a placement slot on its top for holding the filter membrane clip. When the filter membrane clip is placed in the placement slot, its top surface is flush with the top surface of the tray, thus preventing vertical vibration due to the gap. Furthermore, the clamping plates... The upper plate is provided with a ball groove, in which balls are embedded, allowing the balls to roll. The bottom of the tray is provided with a rolling groove that extends in the front-to-back direction. The balls are in contact with the side wall of the rolling groove. When the filter membrane clamp is removed, the tray is pulled forward, and the rolling groove at the bottom of the tray makes rolling contact with the balls at the top of the clamp. By converting the sliding friction between the tray and the clamp into the rolling friction of the balls, the coefficient of friction is greatly reduced. No force is required to pull it out, avoiding the instantaneous acceleration and deceleration vibration when the filter membrane clamp is detached, thereby improving the accuracy of the particulate matter measurement results on the filter membrane. In existing technology, the two spring clips on adjacent clamping plates exert a spring force on the filter membrane clamp, causing frictional resistance on both sides of the clamp. When the filter membrane clamp detaches from the position between the two spring clips along the direction perpendicular to the spring force, it needs to overcome the frictional resistance to detach. After detachment, the filter membrane clamp also needs to decelerate, which causes a momentary violent vibration, causing particles on the filter membrane to fall and affect the final measurement results. The filter membrane clamp storage device provided by this utility model, which facilitates the handling of filter membrane clamps, has a ball groove on the upper surface of the clamping plate with embedded balls, and a rolling groove at the bottom of the tray for holding the filter membrane clamp. This converts the sliding friction between the tray and the clamping plate into rolling friction of the balls, significantly reducing the coefficient of friction. This avoids the user having to use excessive force to pull the tray when handling the filter membrane clamp, thus avoiding the momentary acceleration and deceleration vibration when the filter membrane clamp detaches, and improving the accuracy of the particle measurement results on the filter membrane.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0019] Example 1: like Figures 1-5 As shown, Embodiment 1 of this utility model provides a filter membrane clip storage device that facilitates the handling of filter membrane clips, including a slide 1, several clamping plates 2, several trays 3, and fastening components 4; The slide 1 is grooved; the slide 1 is vertically arranged; if the groove of the slide 1 faces forward, a strip-shaped sliding hole 11 is provided through the side walls on both the left and right sides of the slide 1; the extension direction of the sliding hole 11 is the same as the extension direction of the slide 1; the clamping plate 2 is horizontally arranged; the clamping plate 2 is located inside the slide 1; the edge of the clamping plate 2 is in contact with the inner side wall of the slide 1; the left and right sides of the clamping plate 2 are provided with extensions 21; the extensions 21 extend into the sliding holes 11; the edge of the extensions 21 is in contact with the inner side wall of the sliding holes 11; the bottom clamping plate 2 is fixed to the slide 1; the fastening assembly 4 applies clamping force to the top clamping plate 2 and the bottom clamping plate 2; a tray 3 is placed between two adjacent clamping plates 2; the tray 3 is plate-shaped; if the tray 3 is placed horizontally, the top of the tray 3 is provided with a placement groove 31; The upper surface of the clamping plate 2 is provided with a ball groove 22; a ball 221 is embedded in the ball groove 22; the bottom of the tray 3 is provided with a rolling groove 32; the rolling groove 32 extends in the front-back direction; the ball 221 is in contact with the side wall of the rolling groove 32.

[0020] When using the filter membrane clip storage device provided in Embodiment 1 of this utility model, which facilitates the retrieval of filter membrane clips, the process is divided into assembly and retrieval operations. During assembly, the fastening assembly 4 is first removed from the filter membrane clip storage device, eliminating the clamping force between the top and bottom clamping plates 2. The tray 3 between the two adjacent clamping plates 2 is then pulled out, and the filter membrane clip containing the filter membrane is placed in the placement slot 31 at the top of the tray 3. The tray 3 is then reinserted between the two clamping plates 2. The assembly process is completed from bottom to top. Finally, the fastening assembly 4 secures the top clamping plate 2 and the bottom clamping plate 2. The clamping plate 2 of the upper part applies a clamping force; during the picking operation, the clamping force applied by the fastening assembly 4 to the top clamping plate 2 and the bottom clamping plate 2 is maintained, and the tray 3 between the two adjacent clamping plates 2 is pulled out along the extension direction of the rolling groove 32. At this time, the rolling groove 32 of the tray 3 rolls and contacts the ball bearings 221 embedded in the upper plate surface of the clamping plate 2. After the tray 3 is completely pulled out, the upper clamping plate 2 moves downward under the clamping force, and the extension part 21 of the clamping plate 2 moves downward along the extension direction of the sliding hole 11 until the upper clamping plate 2 and the lower clamping plate 2 are in contact, and the clamping force is maintained again.

[0021] The filter membrane clip storage device provided in Embodiment 1 of this utility model, which facilitates the handling of filter membrane clips, includes a slide 1, several clamping plates 2, several trays 3, and fastening components 4 for stable storage of filter membrane clips. Specifically, the slide 1 is groove-shaped, and its interior space is used to accommodate the filter membrane clips. The slide 1 is positioned vertically, allowing the filter membrane clips to be stacked horizontally within it. This maintains the filter membranes within the clips in a horizontal position, preventing particles from detaching due to tilting and improving the accuracy of particle measurement results. To facilitate explanation of the filter membrane clip storage device's structure, the groove of the slide 1 faces forward, and strip-shaped sliding holes 11 are provided through the side walls on both sides of the slide 1 to restrict the sliding of the clamping plates 2. Specifically, the extending direction of the sliding hole 11 is the same as the extending direction of the slide 1, which is used to restrict the movement of the clamping plate 2 in the vertical direction. The clamping plate 2 is used to clamp the filter membrane clamp and store it stably. Here, the clamping plate 2 is adjustable to maintain the tightness of the clamping of the filter membrane clamp. In order to make the filter membrane clamps stacked horizontally in the slide 1, the clamping plate 2 is set horizontally and the clamping plate 2 is located in the slide 1. The gap between the two clamping plates 2 is used to store the filter membrane clamp. In order to enable the clamping plate 2 to move under the restriction of the sliding hole 11, the left and right sides of the clamping plate 2 are provided with An extension 21 extends into the sliding hole 11. Furthermore, the edge of the clamping plate 2 is made to contact the inner wall of the slide block 1, and the edge of the extension 21 is also made to contact the inner wall of the sliding hole 11. This prevents the clamping plate 2 from shaking on the slide block 1 and also prevents the clamping plate 2 from moving due to friction when the filter membrane clamp is pulled out, thus avoiding errors in the measurement results of particulate matter on the filter membrane caused by the shaking of the clamping plate 2. To achieve adjustable clamping force on the filter membrane clamp and maintain the clamping force of the clamping plate 2, a fastening assembly 4 is used. A clamping force is applied to the top clamping plate 2 and the bottom clamping plate 2. When one of the filter membrane clamps is removed, the fastening assembly will automatically adjust the position of the clamping plate 2 and re-clamp the remaining filter membrane clamps. Furthermore, in order to prevent the filter membrane clamp from falling and vibrating due to the upward contraction of the bottom clamping plate 2, the bottom clamping plate 2 is fixed to the slide 1, so that only the top clamping plate 2 can contract downward and clamp. It should be noted here that the top clamping plate 2 and the bottom clamping plate 2 mentioned above refer to the clamping plate 2 at the highest position and the clamping plate 2 at the lowest position, respectively. To facilitate the easy removal of the filter membrane clip from between two adjacent clamping plates 2 and to prevent severe vibration caused by excessive clamping force applied by the fastening assembly 4 to the top and bottom clamping plates 2 during removal, a tray 3 is placed between the two adjacent clamping plates 2. The tray 3 is plate-shaped and placed horizontally. A placement groove 31 is provided on the top of the tray 3 for placing the filter membrane clip. When the filter membrane clip is placed in the placement groove 31, its top surface is flush with the top surface of the tray 3, thus preventing vertical vibration due to the gap. Furthermore, the upper surface of the clamping plate 2 is provided with ball bearing grooves. 22. The ball groove 22 is embedded with a ball 221, which allows the ball 221 to roll within the ball groove 22. The bottom of the tray 3 is provided with a rolling groove 32, which extends in the front-back direction. The ball 221 is attached to the side wall of the rolling groove 32. When the filter membrane clamp is removed, the tray 3 is pulled forward, and the rolling groove 32 at the bottom of the tray 3 rolls into contact with the ball 221 at the top of the clamping plate 2. By converting the sliding friction between the tray 3 and the clamping plate 2 into the rolling friction of the ball 221, the coefficient of friction is greatly reduced. It is not necessary to pull it out with force, and the instantaneous acceleration and deceleration vibration when the filter membrane clamp is removed is avoided, thereby improving the accuracy of the particulate matter measurement results on the filter membrane. In existing technology, the two spring clips on adjacent clamping plates exert a spring force on the filter membrane clamp, causing frictional resistance on both sides of the filter membrane clamp. When the filter membrane clamp detaches from the position between the two spring clips along the direction perpendicular to the spring force, it needs to overcome the frictional resistance to detach from the position between the two spring clips. After detachment, the filter membrane clamp also needs to decelerate, which causes the filter membrane clamp to vibrate violently for a moment, causing particles on the filter membrane to fall off and affect the final measurement results. The filter membrane clamp storage device provided in Embodiment 1 of this utility model, which facilitates the handling of filter membrane clamps, has a ball groove 22 on the upper surface of the clamping plate 2, with balls 221 embedded in the ball groove 22. A rolling groove 32 is provided at the bottom of the tray 3 that can hold the filter membrane clamp. This converts the sliding friction between the tray 3 and the clamping plate 2 into the rolling friction of the balls 221, greatly reducing the coefficient of friction. This avoids the user having to use a lot of force to pull the tray 3 when handling the filter membrane clamp, thereby avoiding the instantaneous acceleration and deceleration vibration when the filter membrane clamp detaches and improving the accuracy of the particle measurement results on the filter membrane.

[0022] The filter membrane clip storage device provided in Embodiment 1 of this utility model, which facilitates the handling of filter membrane clips, preferably includes two tension springs 41 in order to apply clamping force to the top clamping plate 2 and the bottom clamping plate 2 through the fastening component 4. The two tension springs 41 are located on the left and right sides of the clamping plate 2, respectively, and the two ends of the tension springs 41 are connected to the top clamping plate 2 and the bottom clamping plate 2, respectively. The clamping force applied to the top clamping plate 2 and the bottom clamping plate 2 by the elastic force generated by the tension springs 41 is used. Compared with the existing technology of setting springs on the fixed clamping plate, the clamping force generated by this method has a smaller squeezing force, which can avoid excessive squeezing by the spring type, reduce the frictional resistance to be overcome when picking up and putting down, and at the same time achieve stable storage of the filter membrane clip. Specifically, the extension of the clamping plate 2 has a fastening hole 23 through it in the vertical direction. The tension spring 41 includes a spring body 411 and two hooks 412. The two hooks 412 are located at both ends of the spring body 411 respectively. The two hooks 412 are respectively hooked to the fastening hole 23 of the top clamping plate 2 and the fastening hole 23 of the bottom clamping plate 2. When using the above-mentioned fastening component 4, the hook 412 of the tension spring 41 can also be moved to the fastening hole 23 of any clamp 2 between the top clamp 2 and the bottom clamp 2, so as to facilitate the removal of the filter membrane clamp above the clamp 2. This removal operation is performed from top to bottom.

[0023] The filter membrane clip storage device provided in Embodiment 1 of this utility model is preferably designed to facilitate the removal of filter membrane clips. Since there is a gap after the filter membrane clip between two adjacent clips 2 is removed, the top clip 2 is contracted downward by the elastic force of the tension spring 4. At this time, the upper and lower clips 2 of the removed filter membrane clip will collide, causing other filter membrane clips to vibrate and affecting the accuracy of the particulate matter measurement results on the filter membrane. In order to solve the above problem, elastic buffer protrusions 24 are provided on both the upper and lower surfaces of the clips 2 to buffer the collision between the clips 2.

[0024] The filter membrane clip storage device provided in Embodiment 1 of this utility model, which facilitates the handling of filter membrane clips, preferably includes a limiting ring 222 in the ball groove 22 to allow the ball 22 to roll and embed itself into the ball groove 22. The outer wall of the limiting ring 222 is fixed to the ball groove 22. The limiting ring 222 is placed horizontally, with the direction closest to the center of the limiting ring 222 as the inner side. The upper edge of the limiting ring 222 is bent inward, and the lower edge of the limiting ring 222 is bent inward, forming an arc surface on the inner wall of the limiting ring 222. The diameter of the ball 221 is smaller than the maximum diameter of the inner circle of the annular cross-section of the limiting ring 222, and the diameter of the ball 221 is larger than the minimum diameter of the inner circle of the annular cross-section of the limiting ring 222, so that the ball 221 can slide within the limiting ring 222.

[0025] The filter membrane clip storage device provided in Embodiment 1 of this utility model is preferably provided with a handle 33 on the front side of the tray 3, which makes it easy for the user to pull the tray 3 out from between two adjacent clamps 2.

[0026] In summary, the filter membrane clip storage device provided by this utility model, which facilitates the removal of filter membrane clips, solves the problem in the prior art where, when using spring clips to hold the filter membrane clip, pulling out the filter membrane clip causes a sudden and violent vibration, resulting in particles falling off the filter membrane and affecting the final measurement results. This device allows the filter membrane clip to be smoothly removed without force, preventing particles from scattering due to sudden and violent vibration.

[0027] Those skilled in the art should understand that variations can be implemented by combining existing technology and the above embodiments, and will not be elaborated here. Such variations do not affect the substantive content of this utility model, and will not be elaborated here.

[0028] The preferred embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and the devices and structures not described in detail should be understood as being implemented in a conventional manner in the art; any possible variations and modifications made by those skilled in the art without departing from the technical solution of this utility model, or equivalent embodiments with equivalent changes, do not affect the essential content of this utility model. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the content of the technical solution of this utility model, shall still fall within the protection scope of the technical solution of this utility model.
