Abstract
Description
Technical Field
[0001] This utility model relates to the field of breathing valve testing technology, and in particular to a breathing valve rollover testing platform. Background Technology
[0002] The breather valve rollover test platform is a device used to simulate the accidental overturning of a breather valve during transportation or installation, and to test whether the breather valve can maintain its factory performance after being overturned, impacted, or rolled.
[0003] In the existing technology, the breathing valve is placed on top of the rotating platform, and the angle of the rotating platform is adjusted to make the breathing valve roll off the rotating platform. However, when the rotating platform is rotating, the breathing valve is subject to the combined effects of gravity and centrifugal force, and it is easy for it to roll off prematurely during the rotation process. It is impossible to accurately control the timing of its roll-off, resulting in a large error in the detection effect.
[0004] Therefore, a test platform for the rolling of a breathing valve is proposed. Utility Model Content
[0005] In this section, as well as in the abstract and title of this application, some simplifications or omissions may be made to avoid obscuring the purpose of this section, the abstract, and the title of this application.

[0006] To address the shortcomings of existing technologies, one objective of this utility model is to provide a test platform for the tumbling of a breathing valve.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: a breathing valve rollover test platform, comprising,
[0008] A positioning unit includes a slider, an auxiliary component connected to one side of the slider, and a limit component provided on the slider;
[0009] The slider is provided with a notch;

[0012] The limiting component includes a rectangular block disposed inside the mounting groove. Both the spring and the rectangular block are sleeved on the surface of the positioning post. One end of the spring is connected to the rectangular block, and the other end of the spring is connected to the inner wall of the mounting groove. The rectangular block is fixedly connected to the positioning post.

[0014] The slider is slidably fitted onto the first support plate through a notch;
[0015] The positioning groove matches the positioning post.
[0016] As a preferred embodiment of the breathing valve rollover test platform of this utility model, the limiting component further includes a handle located on the top of the slider. One end of the handle extends into the mounting groove and is connected to a squeezing block. Two protrusions are symmetrically arranged on the squeezing block, and two concave blocks are symmetrically arranged on the rectangular block. Each of the two concave blocks is provided with a first notch, and two second notches are symmetrically formed between the two concave blocks.
[0017] The surfaces of the protrusion, the first notch, and the second notch are all curved surfaces;
[0018] The rectangular block is located at the end of the positioning post near the extrusion block.
[0019] In a preferred embodiment of the breathing valve rollover test platform of this utility model, the rectangular block matches the mounting groove.
[0020] As a preferred embodiment of the breathing valve rollover test platform of this utility model, the limiting component further includes four sets of anti-slip strips on the handle, and the four sets of anti-slip strips are distributed in a ring at equal intervals.
[0021] As a preferred embodiment of the breathing valve rollover test platform of this utility model, it further includes a test unit, which includes a rotating platform and a rollover platform;
[0022] The rotating platform includes a support, on which a first cylinder is rotatably connected. The end of the first cylinder away from the bottom support is rotatably connected to a placement plate, and the end of the placement plate away from the first cylinder is rotatably connected to the support.
[0023] Both the first support plate and the second support plate are located on top of the placement plate.
[0024] As a preferred embodiment of the breathing valve tumbling test platform of this utility model, both the rotating platform and the tumbling platform are equipped with railings.

After completion, release the hand, and the positioning column will reset under the action of the spring force. The positioning column is fixed to the slider by the spring force, and the auxiliary component fixes one end of the breather valve. This prevents the breather valve from rolling prematurely due to the combined effect of gravity and centrifugal force when the rolling angle changes, thus avoiding the problem of inaccurate control of the rolling timing and resulting in large errors in the test results. When the device is adjusted to the appropriate angle and position, release the fixation on the breather valve to allow it to roll down and test the performance of the breather valve.

[0038] To make the objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0039] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0040] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0041] Reference Figure 1 This embodiment provides a breathing valve rollover test platform, including a positioning unit 100, which includes a slider 101. An auxiliary component 102 is connected to one side of the slider 101. A limit component 103 is provided on the slider 101. A notch 101a is provided on the slider 101. The limit component 103 includes a spring 103a and a positioning post 103b provided on the slider 101. The spring 103a is connected to the positioning post 103b. One end of the positioning post 103b extends into the notch 101a.
[0042] The auxiliary component 102 is used to limit one end of the breathing valve. It can be a conventional mechanical gripper, a block that matches one end of the breathing valve, or other clamps. As long as it can limit one end of the breathing valve and ensure that the device will not detach during rotation when in contact with the end of the breathing valve.
[0043] In the initial state, the positioning post 103b slides through the slider 101, and one end of the spring 103a is connected to the slider 101, while the other end of the spring 103a is connected to the positioning post 103b.
[0044] When using the device, first pull the positioning post 103b to disengage it from the recess 101a, then slide the slider 101 into the appropriate position. After this, release the hand, and the positioning post 103b will return to its original position under the elastic force of the spring 103a. The positioning post 103b is fixed to the slider 101 by the elastic force of the spring 103a. The auxiliary component 102 fixes one end of the breathing valve to prevent it from rolling down prematurely due to the combined effect of gravity and centrifugal force when the angle of the breathing valve changes, thus avoiding the problem of inaccurate control of the timing of its roll-down and resulting in a large error in the detection effect. When the device is adjusted to the appropriate angle and position, release the fixation on the breathing valve to allow it to roll down and test the performance of the breathing valve.
[0045] Reference Figure 1 Furthermore, the slider 101 has an installation groove 101b, which communicates with the recess 101a. The positioning post 103b is located inside the installation groove 101b. The limiting component 103 includes a spring 103a and a rectangular block 103c disposed inside the installation groove 101b. Both the spring 103a and the rectangular block 103c are sleeved on the surface of the positioning post 103b. One end of the spring 103a is connected to the rectangular block 103c, and the other end of the spring 103a is connected to the inner wall of the installation groove 101b. The rectangular block 103c is fixedly connected to the positioning post 103b.
[0046] Unlike the above embodiments, in this embodiment, the spring 103a is connected to the positioning post 103b via the rectangular block 103c, which reduces the difficulty of processing and facilitates the installation of the spring 103a. In the initial state, the rectangular block 103c can contact the bottom inner wall of the mounting groove 101b, and the two ends of the spring 103a that are far apart from each other can contact the top of the rectangular block 103c and the inner wall of the mounting groove 101b respectively. Its overall operation is the same as that of the above embodiments, and will not be repeated here.
[0047] Reference Figures 1-3 Furthermore, it also includes a support unit 200, which includes a first support plate 201 and a second support plate 202 arranged in parallel. The first support plate 201 and the second support plate 202 are each provided with a plurality of positioning grooves 203. The plurality of positioning grooves 203 are used to adjust and set the initial position of the breathing valve rolling down. The slider 101 is slidably sleeved on the first support plate 201 through the notch 101a. The positioning grooves 203 match the positioning posts 103b.
[0048] In use, first pull the positioning post 103b to disengage it from the positioning groove 203. Simultaneously, the positioning post 103b compresses the spring 103a via the rectangular block 103c. When the positioning post 103b is completely disengaged from the positioning groove 203, slide the slider 101 onto the first support plate 201 to the appropriate position. After this, release the positioning post 103b, and under the elastic force of the spring 103a, the rectangular block 103c drives the positioning post 103b to reset, allowing it to insert into the corresponding positioning groove 203, thus positioning the slider 101. The auxiliary component 102 then positions one end of the breather valve. Unlike the previous embodiment, in this embodiment, the positioning post 103b is inserted into the positioning groove 203 to fix the slider 101, which is more stable. Furthermore, based on the positioning groove 203 settings, multi-position rolling detection can be performed, improving the accuracy of the breather valve's ability to maintain its factory performance during rolling collisions.
[0049] Reference Figures 1-2 Furthermore, the limiting component 103 also includes a handle 103d located on the top of the slider 101. One end of the handle 103d extends into the mounting groove 101b and is connected to a pressing block 103e. Two protrusions 103f are symmetrically arranged on the pressing block 103e, and two concave blocks 103g are symmetrically arranged on the rectangular block 103c. Each of the two concave blocks 103g is provided with a first notch 103h, and two second notches 103i are symmetrically formed between the two concave blocks 103g. The surfaces of the protrusions 103f, the first notch 103h, and the second notch 103i are all arc surfaces. The arc surface facilitates the protrusions 103f pressing the concave blocks 103g. The rectangular block 103c is located at the end of the positioning post 103b near the pressing block 103e.
[0050] Unlike the above embodiments, in this embodiment, one end of the positioning post 103b is located inside the recess 101a, and the other end of the positioning post 103b is located inside the mounting groove 101b.
[0051] Among them, the two first notches 103h and the two second notches 103i are distributed in a ring at equal intervals. In the initial state, when the positioning post 103b is inserted into the positioning groove 203, the ends of the two protrusions 103f are respectively located inside the two second notches 103i, and the spring 103a is compressed.
[0052] When the handle 103d is rotated, the handle 103d drives the two protrusions 103f to first press the groove surface of the second notch 103i through the pressing block 103e and drive the two concave blocks 103g to descend. When the two protrusions 103f correspond to the positions of the two second notches 103i respectively, the rectangular block 103c is reset under the action of the elastic force of the spring 103a. The rectangular block 103c drives the two first notches 103h to fit with the two protrusions 103f. At the same time, the rectangular block 103c drives the positioning post 103b to disengage from the inside of the positioning groove 203, releasing the connection between the slider 101 and the first support plate 201.
[0053] When the slider 101 is adjusted to the appropriate position, the handle 103d is rotated. The handle 103d drives the two protrusions 103f to first squeeze the groove surface of the first notch 103h through the pressing block 103e and drive the two concave blocks 103g to descend. The two concave blocks 103g drive the positioning post 103b to descend through the rectangular block 103c, so that the positioning post 103b is inserted into the corresponding positioning groove 203, thus completing the locking of the slider 101 and thereby completing the locking of the auxiliary part 102.
[0054] Unlike the above embodiments, in this embodiment, when adjusting the position of the slider 101, simply turning the handle 103d will cause the positioning post 103b to disengage from the positioning groove 203. This means that the slider 101 can be adjusted without constantly pulling the positioning post 103b, making it easier for operators to adjust the position of the auxiliary component 102. In particular, when the breathing valve is placed in the appropriate position, slight adjustments to the position of the auxiliary component 102 are required, making the adjustment even simpler.
[0055] Reference Figures 1-5 The rectangular block 103c matches the mounting slot 101b, ensuring that the rectangular block 103c can only move up and down in a straight line inside the mounting slot 101b, thereby ensuring that the spring 103a will only be compressed in a straight line, increasing the service life of the spring 103a.
[0056] Reference Figures 2-6 The limiting component 103 also includes four sets of anti-slip strips 103j disposed on the handle 103d. The four sets of anti-slip strips 103j are distributed in a ring at equal intervals. The four sets of anti-slip strips 103j correspond to the four sides of the top of the slider 101. The four sets of anti-slip strips 103j not only facilitate the operator to turn the handle 103d, but also determine the rotation angle of the handle 103d. The four sets of anti-slip strips 103j correspond to the positions of the two first notches 103h and the two second notches 103i. By observing whether the four sets of anti-slip strips 103j correspond to the positions of the top sides of the slider 101, it can be determined whether the handle 103d has rotated ninety degrees.
[0057] Multiple anti-slip strips 103j can be set in each group, with the middle one corresponding to the side of the slider 101, which makes it easier for the staff to turn the handle 103d.
[0058] Reference Figures 1-5 Furthermore, it also includes a test unit 300, which includes a rotating platform 301 and a tumbling platform 302. The rotating platform 301 includes a support 301a, on which a first cylinder 301b is rotatably connected. The end of the first cylinder 301b away from the bottom support 301a is rotatably connected to a placement plate 301c. The end of the placement plate 301c away from the first cylinder 301b is rotatably connected to the support 301a. The first support plate 201 and the second support plate 202 are both located on the top of the placement plate 301c.
[0059] In this embodiment, both the first support plate 201 and the second support plate 202 are fixedly installed on the top of the rotating platform 301;
[0060] When the slider 101 drives the auxiliary component 102 to adjust to the appropriate position, the auxiliary component 102 fixes one end of the breathing valve. Then, by opening the first cylinder 301b, the first cylinder 301b drives the placement plate 301c to rotate. When the breathing valve is adjusted to the appropriate rolling position, it contacts the auxiliary component 102 to fix the breathing valve, so that the breathing valve rolls off the placement plate 301c to the top of the tumbling platform 302.
[0061] In this embodiment, the rolling position of the breathing valve can be adjusted, and it will only roll down after reaching a suitable angle, thus avoiding the breathing valve rolling down when the placement plate 301c is adjusted, which would affect the accuracy of the detection.
[0062] Reference Figures 1-6 Furthermore, both the rotating platform 301 and the tumbling platform 302 are equipped with railings 301d. The railings 301d prevent the breathing valve from rolling off the tumbling platform 302 and hitting the staff.
[0063] Reference Figure 2 , Figure 5 and Figure 6Furthermore, the placement plate 301c is also provided with a drive unit 301e, which is connected to the first support plate 201. The drive unit 301e can be a cylinder, an electric telescopic rod, or a regular handle, preferably a cylinder or an electric telescopic rod. The drive unit 301e can directly drive the first support plate 201 to move, thereby adjusting the distance between the first support plate 201 and the second support plate 202, which facilitates the testing of different types of breathing valves. At the same time, the auxiliary component 102 can be a conventional limit block, which can be used to control the breathing valve. After one end is limited, the first support plate 201 is moved by the drive component. The first support plate 201 moves the breathing valve by the slider 101 and the auxiliary component 102, so that the other end of the breathing valve contacts the second support plate 202, thereby fixing the breathing valve. At the same time, when the placement plate 301c is adjusted to a suitable angle, the first support plate 201 is moved by the control drive unit 301e, so that the first support plate 201 moves by the slider 101 and the auxiliary component 102, thereby releasing the limitation on the breathing valve, allowing the breathing valve to roll down directly.
[0064] Reference Figures 3-5 Furthermore, both the positioning post 103b and the rolling platform 302 are made of carbon steel WCB. This material has a mature casting process and a compressive strength of up to 490MPa. Its corrosion resistance can be improved by galvanizing or spraying with epoxy resin.
[0065] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
