Description

Technical Field

[0001] This utility model relates to the field of moisture testing technology, and in particular to an auxiliary device for moisture testing. Background Technology

[0002] Currently, moisture testing of conductive pastes primarily relies on syringes to extract samples. These samples are then injected into a moisture meter through a filter membrane and needle for testing.

[0003] However, due to the significant differences in particle size among different conductive slurries, larger particle sizes encounter considerable resistance when passing through needle filter membranes. This resistance causes a sharp increase in internal pressure within the membrane, making it difficult for the slurry to be expelled smoothly, thus necessitating improvements. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an auxiliary device for moisture testing. A limiting body provides a stable support platform, and a limiting cavity accommodates and secures the syringe. The first and second limiting structures respectively limit the filter membrane and seal the limiting cavity, ensuring the stability and sealing of the syringe. An assisting structure, acting as a force transmission medium, is inserted into the limiting cavity and forms an abutment with the push rod and the second limiting structure, achieving effective force transmission and enhancement. When the user pushes the assisting structure, it transmits force to the push rod, thereby pushing the liquid out of the syringe and saving the effort required to eject the slurry.

[0005] To achieve the above objectives, the present invention provides a moisture testing auxiliary device, comprising a limiting body, a first limiting structure, an assisting structure, and a second limiting structure.

[0006] The limiting body has a limiting cavity axially arranged, the syringe is housed in the limiting cavity and the syringe needle and filter membrane both extend outside the limiting body;

[0007] The first limiting structure is connected to one end of the limiting body and is used to limit the filter membrane of the syringe; the second limiting structure is connected to the other end of the limiting body and is used to block the limiting cavity.

[0008] The assist structure is inserted into the limiting cavity and abuts against the syringe plunger and the second limiting structure.

[0009] Preferably, the limiting body is radially provided with a clearance groove that penetrates the limiting cavity;

[0010] The assist structure includes a first telescopic part, a second telescopic part, and a control part that controls the extension and retraction of the first telescopic part and the second telescopic part. The control part is connected between the first telescopic part and the second telescopic part and drives the first telescopic part and the second telescopic part to move closer to each other or further away from each other.

[0011] The first telescopic part abuts against the syringe plunger, the second telescopic part abuts against the second limiting structure, and the control part extends out of the limiting body through the clearance groove.

[0012] Preferably, the control unit includes a first nut, a second nut, and a screw. The screw is provided with a first thread and a second thread, and the first thread and the second thread are arranged in opposite directions. The first nut is threadedly connected to the first thread, and the second nut is threadedly connected to the second thread.

[0013] Both the first telescopic part and the second telescopic part include a first telescopic member and a second telescopic member. The first telescopic member and the second telescopic member are hinged together. The end of the first telescopic member away from the hinge of the second telescopic member is hinged to a first nut, and the end of the second telescopic member away from the hinge of the first telescopic member is hinged to a second nut.

[0014] Preferably, a handle is provided at one end of the screw.

[0015] Preferably, the first limiting structure includes a needle nut and a filter membrane nut;

[0016] The needle nut is connected to one end of the filter membrane nut, and the end of the filter membrane nut away from the needle nut is connected to the limiting body;

[0017] Both the needle nut and the filter membrane nut are provided with needle holes that allow the syringe needle to pass through. The syringe needle extends out of the limiting body through the needle holes, and the syringe filter membrane is confined between the filter membrane nut and the limiting body.

[0018] Preferably, the first limiting structure further includes an upper adhesive pad and a lower adhesive pad;

[0019] The upper rubber pad is disposed between the filter membrane nut and the filter membrane of the syringe, and the lower rubber pad is disposed between the filter membrane of the syringe and the limiting body.

[0020] Preferably, the second limiting structure is a limiting plug or a limiting nut.

[0021] The beneficial effects of this invention are as follows: This invention provides a stable support platform through a limiting body, which accommodates and fixes the syringe through a limiting cavity. The first limiting structure and the second limiting structure respectively limit the filter membrane and seal the limiting cavity, ensuring the stability and sealing of the syringe. The assisting structure, as a medium for force transmission, is inserted into the limiting cavity and forms an abutment with the push rod and the second limiting structure, achieving effective force transmission and enhancement. When the user pushes the assisting structure, it transmits force to the push rod, thereby pushing the liquid in the syringe out, saving the force required to push out the slurry.

[0022] The addition of upper and lower rubber pads to the first limiting structure enhances the overall stability of the device. These pads reduce membrane swaying and displacement during installation and use, ensuring the membrane remains in the correct position, thus improving injection accuracy and stability. They also prevent the membrane from rupturing under excessive pressure due to its relatively weak compressive strength. This reduces the risk of membrane rupture, slurry splashing, and the inconvenience caused by impaired testing accuracy and subsequent cleaning. Attached Figure Description

[0028] The present invention will now be described in detail with reference to the accompanying drawings.

[0029] See Figures 1 to 3 As shown, the present invention provides a moisture testing auxiliary device, which includes a limiting body 1, a first limiting structure 2, an assisting structure 3, and a second limiting structure 4.

[0030] The limiting body 1 has a limiting cavity 11 arranged axially. The syringe is housed in the limiting cavity 11 and the syringe needle and filter membrane both extend beyond the limiting body 1.

[0031] The first limiting structure 2 is connected to one end of the limiting body 1 and is used to limit the filter membrane of the syringe. The second limiting structure 4 is connected to the other end of the limiting body 1 and is used to block the limiting cavity 11.

[0032] The assist structure 3 is inserted into the limiting cavity 11 and abuts against the syringe plunger and the second limiting structure 4.

[0033] The syringe is fixed by the limiting cavity 11 inside the limiting body 1 to ensure the stability of the syringe during use and prevent accidents caused by shaking or misoperation.

[0034] The first limiting structure 2 and the second limiting structure 4 respectively limit the filter membrane of the syringe and the sealing limiting cavity 11, further enhancing the stability of the syringe and preventing liquid leakage or contamination.

[0035] The auxiliary structure 3 provides users with additional force support when pushing the syringe plunger, reducing the difficulty of operation, and is especially suitable for situations where greater pressure needs to be applied.

[0036] The assist structure 3 is inserted into the limiting cavity 11, forming an effective contact relationship with the push rod and the second limiting structure 4, ensuring the accuracy and effectiveness of force transmission.

[0037] This device is suitable for syringes of various sizes. By adjusting the size and shape of the first limiting structure 2 and the second limiting structure 4 of the limiting body 1, it can be compatible with syringes of different sizes, thus improving the versatility and practicality of the device.

[0038] In use, the limiting body 1 provides a stable support platform, which accommodates and secures the syringe through the limiting cavity 11. The first limiting structure 2 and the second limiting structure 4 respectively limit the filter membrane and seal the limiting cavity 11, ensuring the stability and sealing of the syringe. The assisting structure 3, as a medium for force transmission, is inserted into the limiting cavity 11 and forms an abutment with the push rod and the second limiting structure 4, achieving effective force transmission and enhancement. When the user pushes the assisting structure 3, it transmits force to the push rod, thereby pushing the liquid in the syringe out, saving the force required to eject the slurry.

[0039] See Figure 1 and Figure 3 As shown, the limiting body 1 of this embodiment is provided with a relief groove 12 that penetrates the limiting cavity 11 in the radial direction, so that the control part 33 can extend outside the limiting body 1, which is convenient for user operation and control.

[0040] The design of the clearance slot 12 not only provides operating space, but also maintains the compactness and integrity of the device, without affecting its overall aesthetics and practicality.

[0041] The assist structure 3 includes a first telescopic part 31, a second telescopic part 32, and a control part 33 that controls the extension and retraction of the first telescopic part 31 and the second telescopic part 32. The control part 33 is connected between the first telescopic part 31 and the second telescopic part 32 and drives the first telescopic part 31 and the second telescopic part 32 to move closer to each other or further away from each other. By driving the first telescopic part 31 and the second telescopic part 32, the amount of assistance to the syringe plunger can be adjusted.

[0042] This adjustability allows the device to be adapted to syringes of different sizes and pressures, improving its versatility and practicality.

[0043] The first telescopic part 31 abuts against the syringe plunger, and the second telescopic part 32 abuts against the second limiting structure 4, ensuring a stable transmission of force. This abutting relationship not only provides effective force support but also prevents syringe damage or liquid leakage caused by uneven force transmission.

[0044] The control unit 33 extends out of the limiting body 1 via the clearance groove 12. The user can adjust and control the assist structure simply by operating the control unit 33, without the need for additional tools or steps, thus improving the ease of operation.

[0045] With a well-designed layout and the extension position of the control unit 33, users can clearly see and control the status of the power assist structure, reducing safety hazards caused by misoperation.

[0046] See Figure 3 As shown, the control unit 33 of this embodiment includes a first nut 331, a second nut 332 and a screw 333. The screw 333 is provided with a first thread and a second thread, and the first thread and the second thread are arranged in opposite directions. The first nut 331 is threadedly connected to the first thread, and the second nut 332 is threadedly connected to the second thread.

[0047] By configuring a screw 333 with a first thread and a second thread, wherein the first thread and the second thread have opposite thread directions, the first nut 331 and the second nut 332 can move in opposite directions when the screw 333 rotates. This design allows for precise adjustment of the extension and retraction of the first telescopic part 31 and the second telescopic part 32, thereby achieving precise control of the syringe plunger.

[0048] Both the first telescopic part 31 and the second telescopic part 32 include a first telescopic member 301 and a second telescopic member 302. The first telescopic member 301 and the second telescopic member 302 are hinged together. One end of the first telescopic member 301 away from the hinge point of the second telescopic member 302 is hinged to the first nut 331, and one end of the second telescopic member 302 away from the hinge point of the first telescopic member 301 is hinged to the second nut 332.

[0049] Both the first telescopic section 31 and the second telescopic section 32 employ hinged first telescopic member 301 and second telescopic member 302. This design not only provides flexible telescopic capability but also ensures structural stability. When the screw 333 drives the nut to move, the telescopic members can maintain a stable hinged relationship, preventing assist failure due to deformation or loosening.

[0050] Users can adjust the first telescopic part 31 and the second telescopic part 32 simply by rotating the screw 333, without the need for additional tools or complicated operating procedures. This design simplifies the operation process and improves the user experience.

[0051] See Figure 3 As shown, a handle 334 is provided at one end of the screw 333 in this embodiment.

[0052] The handle 334 at one end of the screw 333 provides the user with an intuitive and easy-to-operate component. The user can simply rotate the handle 334 to drive the screw 333 to rotate, thereby adjusting the extension and retraction of the first telescopic part 31 and the second telescopic part 32. This design greatly simplifies the operation process and improves ease of use.

[0053] See Figure 2 As shown, the first limiting structure 2 in this embodiment includes a needle nut 21 and a filter membrane nut 22.

[0054] The needle nut 21 is connected to one end of the filter membrane nut 22, and the end of the filter membrane nut 22 away from the needle nut 21 is connected to the limiting body 1.

[0055] The design of the first limiting structure 2, particularly the combination of the needle nut 21 and the filter membrane nut 22, ensures the stability and safety of the syringe needle during use. The needle nut 21 is connected to the filter membrane nut 22, together providing support for the needle and preventing it from accidentally falling off or moving during use, thereby reducing the risk of needlestick injuries.

[0056] Both the needle nut 21 and the filter membrane nut 22 are provided with needle holes that allow the syringe needle to pass through. The syringe needle extends out of the limiting body 1 through the needle hole, and the syringe filter membrane is limited between the filter membrane nut 22 and the limiting body 1.

[0057] The connection design between the filter membrane nut 22 and the limiting body 1 allows the syringe's filter membrane to be confined between them. This design not only ensures the stability and positional accuracy of the filter membrane but also makes filter membrane replacement and cleaning simple and quick. Users can easily disassemble and reinstall the filter membrane as needed, improving the flexibility and practicality of the device.

[0058] Users simply need to pass the syringe needle through the needle hole of the needle nut 21 and the filter membrane nut 22, and then connect the filter membrane nut 22 to the limiting body 1. This design simplifies the operation process and reduces the complexity and time cost for users.

[0059] See Figure 2 As shown, the first limiting structure 2 in this embodiment also includes an upper adhesive pad 23 and a lower adhesive pad 24;

[0060] The upper rubber pad 23 is disposed between the filter membrane nut 22 and the filter membrane of the syringe, and the lower rubber pad 24 is disposed between the filter membrane of the syringe and the limiting body 1.

[0061] By adding an upper rubber pad 23 and a lower rubber pad 24 to the first limiting structure 2, the sealing effect of the device on the syringe filter membrane is significantly improved. The upper rubber pad 23 and the lower rubber pad 24 are located between the filter membrane nut 22 and the filter membrane, and between the filter membrane and the limiting body 1, respectively, effectively preventing liquid leakage during injection and ensuring the accuracy and safety of injection.

[0062] The upper and lower rubber gaskets 23 and 24 not only provide a seal but also protect the filter membrane. They reduce wear and damage to the filter membrane under external forces, extending its service life. Furthermore, the softness of the gaskets cushions the pressure generated during injection, further protecting the filter membrane from damage.

[0063] The addition of the upper and lower adhesive pads 23 and 24 further enhances the stability of the entire device. They reduce the shaking and displacement of the filter membrane during installation and use, ensuring that the filter membrane always remains in the correct position, thereby improving the accuracy and stability of injection.

[0064] To prevent the filter membrane from rupturing under excessive pressure due to its weak compressive strength. To reduce the problems caused by filter membrane rupture, slurry splashing, affecting the accuracy of testing, and causing inconvenience in subsequent cleaning.

[0065] See Figure 1 and Figure 3 As shown, the second limiting structure 4 in this embodiment is a limiting plug or a limiting nut. It provides additional support and fixation for the entire syringe auxiliary device. This design enhances the structural stability of the device and reduces the risk of deformation or damage caused by external forces during use.

[0066] This embodiment uses the second limiting structure 4 as an example of a limiting nut. Users can adjust its position by rotating the nut, thereby achieving precise control over the syringe plunger or piston. This adjustment function allows users to adjust the syringe stroke or pressure according to actual needs, improving the accuracy and controllability of injection.

[0067] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
