Description

Technical Field

[0001] This utility model relates to the field of oxygen concentration detection technology, and in particular to a wall-mounted oxygen measuring device. Background Technology

[0002] The oxygen concentration detection device in an oxygen concentrator is a key component to ensure that the oxygen concentration output by the oxygen concentrator meets the standards.

[0003] When using an oxygen measuring device, it needs to be connected to an oxygen delivery pipeline. However, the existing connection method is usually to directly insert the pipeline into the pipe joint surface of the oxygen measuring device, which has a poor fixing effect on the pipeline. The vibration generated during the operation of the oxygen generator can easily cause the pipeline to detach from the pipe joint, affecting the delivery of oxygen. Utility Model Content

[0004] The purpose of this invention is to solve the problem that pipelines are easily detached from pipe joints in the prior art, and to propose a wall-mounted oxygen measuring device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A wall-mounted oxygen measuring device includes two pipe joints fixed to the lower surface of the oxygen measuring device body and a clamping assembly for fastening the pipe joints and pipes. The clamping assembly includes two clamping plates that slide symmetrically on both sides of the pipe joints. A limiting assembly is provided on the lower surface of the oxygen measuring device body to simultaneously limit the position of the two clamping plates in one direction.

[0006] In some embodiments, the lower ends of the two clamps are arc surfaces that mate with the outer surface of the pipe, and the clamps are inclined with the end near the arc surface facing the pipe joint.

[0007] In some embodiments, the limiting component includes a toothed plate that slides on the lower surface of the oxygen measuring device body and a locking tooth fixed to the side of the clamp plate near the toothed plate. The toothed plate has a plurality of symmetrically formed slots on its surface, and the slots cooperate with the locking teeth. A pull rod slides on the lower surface of the oxygen measuring device body, one end of which is fixed to the surface of the toothed plate. A spring is sleeved on the surface of the pull rod for pushing the toothed plate to slide towards the pipe joint.

[0008] In some embodiments, an installation structure is provided on the back of the oxygen measuring device body. The installation structure includes a fixed plate fixed inside the oxygen generator and two sliding plates that cooperate with the fixed plate. The fixed plate has an installation groove on the side near the oxygen measuring device body. The two sliding plates slide horizontally on the back of the oxygen measuring device body and are symmetrically arranged.

[0009] In some embodiments, the back of the oxygen measuring device body is provided with an adjustment component for driving two sliding plates to move closer or further apart. The adjustment component includes a positive and negative threaded column rotating on the back of the oxygen measuring device body and two top plates threadedly connected to the surfaces of the positive and negative threaded column. The two sliding plates are respectively provided with a first inclined surface that cooperates with the two ends of the top plate on opposite sides.

[0010] In some embodiments, a tension spring is fixed between the two skateboards for pulling the two skateboards closer together.

[0011] Compared with the prior art, the present invention provides a wall-mounted oxygen measuring device, which has the following beneficial effects.

[0012] 1. This utility model, by setting a clamping component and a limiting component, enables two clamping plates to clamp the pipeline on the surface of the pipe joint. At the same time, the clamping plates are limited in position by the clamping teeth and toothed plates to prevent the clamping plates from sliding away from the pipe joint, which would cause the clamping plates to lose their clamping force on the pipeline.

[0013] 2. This utility model, by setting an installation structure, allows the oxygen measuring device body to be inserted into the installation groove on the surface of the fixing plate via a sliding plate. The top plate drives the sliding plate to abut against the inner wall of the installation groove, thereby facilitating the installation of the oxygen measuring device body inside the oxygen generator, achieving the purpose of quick installation and fixation, and making it convenient to remove the oxygen measuring device body for calibration.

[0014] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A wall-mounted oxygen measuring device includes two pipe joints 2 fixed to the lower surface of the device body 1 and a clamping assembly 3 for fastening the pipe joints 2 and the pipeline. The clamping assembly 3 includes two clamping plates 301 symmetrically sliding on both sides of the pipe joints 2. (Refer to...) Figure 2 The lower ends of the two clamping plates 301 are arc surfaces that fit with the outer surface of the pipeline, and the clamping plates 301 are inclined, with the end near the arc surface facing the pipe joint 2. A right-angle plate 302 is fixed on the side of the clamping plate 301 away from the pipe joint 2. Anti-slip texture is provided on the arc surface of the lower end of the clamping plate 301. A limiting component 4 is provided on the lower surface of the oxygen measuring device body 1 to simultaneously limit the position of the two clamping plates 301 in one direction. The limiting component 4 includes a toothed plate 401 that slides on the lower surface of the oxygen measuring device body 1 and a locking tooth 402 fixed on the side of the clamping plate 301 near the toothed plate 401. The toothed plate 401 has multiple symmetrically opened slots on its surface. One side of the slot is a second inclined surface that facilitates the sliding of the locking tooth 402 toward the pipe joint 2. The slot and the locking tooth 402 cooperate. The sliding direction of the toothed plate 401 is perpendicular to the sliding direction of the clamping plate 301. A pull rod 403 slides on the lower surface of the oxygen measuring device body 1. One end of the pull rod 403 is fixed to the surface of the toothed plate 401. A spring 404 is sleeved on the surface of the pull rod 403 to push the toothed plate 401 to slide toward the pipe joint 2.

[0023] Understandably, by pressing the two right-angle plates 302, the two clamping plates 301 slide towards the pipe connector 2. Under the action of the second inclined surface of the toothed plate 401, the clamping plates 301 and the locking teeth 402 can slide smoothly towards the pipe connector 2 on the surface of the toothed plate 401, thereby clamping the pipe inserted into the surface of the pipe connector 2 at the lower end of the clamping plate 301, preventing the pipe from detaching from the surface of the pipe connector 2 due to vibration generated when the oxygen generator 6 is working. By setting the toothed plate 401 and the locking teeth 402, the spring 404 pushes the toothed plate 401 to engage with the surface of the locking teeth 402, thereby limiting the position of the clamping plate 301 and preventing the clamping plate 301 from sliding away from the pipe connector 2, which would cause the clamping plate 301 to lose its clamping force on the pipe.

[0024] Specifically, the back of the oxygen measuring device body 1 is provided with an installation structure 5. The installation structure 5 includes a fixing plate 501 fixed inside the oxygen generator 6 and two sliding plates 502 that cooperate with the fixing plate 501. The fixing plate 501 is fixed inside the oxygen generator 6 by bolts. The fixing plate 501 has an installation groove 5011 on the side near the oxygen measuring device body 1. The installation groove 5011 is a dovetail groove with an open top. The two sliding plates 502 slide horizontally on the back of the oxygen measuring device body 1 and are symmetrically arranged. The oxygen measuring device body 1 has an adjustment component 503 on its back for moving two sliding plates 502 closer to or further apart. The adjustment component 503 includes a positive and negative threaded post 5031 that rotates on the back of the oxygen measuring device body 1 and two top plates 5032 that are threaded to the surface of the positive and negative threaded post 5031. The moving direction of the two top plates 5032 is perpendicular to the sliding direction of the sliding plates 502. The opposite side of the two sliding plates 502 is provided with a first inclined surface 5021 that cooperates with the two ends of the top plate 5032. A tension spring 5033 is fixed between the two sliding plates 502. The side of the two sliding plates 502 that is further apart cooperates with the inner wall of the dovetail groove. A rotating handle is fixed at the upper end of the positive and negative threaded post 5031.

[0025] Understandably, after a period of use, the oxygen measuring device body 1 is prone to measurement deviations and requires periodic calibration. However, the existing installation method cannot quickly disassemble and reassemble the oxygen measuring device body 1, resulting in low calibration efficiency. Therefore, the fixing plate 501 is installed inside the oxygen generator 6 with bolts, and the two sliding plates 502 are inserted into the mounting slots 5011. By rotating the handle, the positive and negative threaded columns 5031 are rotated, causing the two top plates 5032 to move away from each other. The first inclined surface 5021 and the top plate 5032 are then aligned. With the cooperation of the two slide plates 502, the two slide plates 502 are moved away from each other and are engaged with the inner wall of the mounting groove 5011, thereby fixing the oxygen measuring device body 1. When it is necessary to remove the oxygen measuring device body 1 from the surface of the fixing plate 501, the positive and negative threaded post 5031 drives the two top plates 5032 to move closer to each other, releasing the resistance to the two slide plates 502. Under the action of the tension spring 5033, the two slide plates 502 move closer to each other, making it easier to remove the slide plates 502 from the mounting groove 5011 and quickly remove the oxygen measuring device body 1.

[0026] In this invention, the fixing plate 501 is installed inside the oxygen generator 6 by bolts, and the two sliding plates 502 are inserted into the mounting groove 5011. The rotating handle drives the positive and negative threaded columns 5031 to rotate, causing the two top plates 5032 to move the two sliding plates 502 away from each other, thus securing the two sliding plates 502 to the inner wall of the mounting groove 5011 and fixing the oxygen measuring device body 1. After the pipeline is inserted into the surface of the pipe connector 2, the two right-angle plates 302 are pressed simultaneously, causing the two clamping plates 301 to slide towards the pipe connector 2, thus moving the clamping plates 301... The lower end clamps the pipe inserted into the surface of the pipe connector 2 to prevent the pipe from detaching from the surface of the pipe connector 2 due to vibration generated during the operation of the oxygen generator 6. At the same time, the spring 404 pushes the toothed plate 401 to engage with the surface of the clamping teeth 402, limiting the position of the clamping plate 301 and preventing the clamping plate 301 from sliding away from the pipe connector 2, which would cause the clamping plate 301 to lose its clamping force on the pipe. When it is necessary to pull out the pipe, the pull rod 403 is pulled to drive the toothed plate 401 to disengage from the clamping teeth 402, thereby separating the clamping plate 301 from the pipe and facilitating the removal of the pipe.
