Description

Technical Field

[0001] This utility model relates to the field of liquid crystal ion density testing technology, and more specifically to a testing device for liquid crystal ion density in the preparation of liquid crystal materials. Background Technology

[0002] Ionic liquid crystals are a highly attractive type of liquid crystal material, composed of cations and anions, combining the excellent properties of liquid crystals and ionic liquids. Through ion self-assembly strategies, ionic liquid crystal materials with different properties can be prepared. Gemini surfactants offer greater structural designability, enabling the construction of a series of novel surfactant ionic liquid crystal materials and revealing their assembly process and mechanism. Ionic liquid crystals possess efficient ion channels, making them easy to device and manipulate. Typically, when testing the density of ionic liquid crystals, a conduction rod is required for testing.

[0003] Chinese patent CN217639298U discloses a liquid crystal ion for preparing liquid crystal materials. By setting an energized contact and a connecting contact, the specifications and size of the needle can be changed according to the actual situation, which increases the functionality of the testing device and improves the practicality of the testing device.

[0004] However, when replacing the transmission rod, the patented design requires continuous rotation of the mounting base by the operator due to the threaded connection of the transmission rod. This lack of a convenient disassembly mechanism necessitates frequent operation and is inconvenient. Furthermore, the absence of a mechanism to restrict the position of the transmission rod when not in use results in it intermittently colliding with the connecting contact when held by the operator, potentially damaging the contact and affecting the testing process. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a testing device for liquid crystal ion density in liquid crystal material preparation. This addresses the problems in the prior art where the lack of a convenient mechanism for disassembling the transmission rod leads to frequent operation by staff, which is inconvenient. Furthermore, the absence of a mechanism to restrict the position of the transmission rod when not in use results in the transmission rod intermittently colliding with the connecting contact when held by the staff, which can easily damage the connecting contact and affect the testing process.

[0006] This utility model provides the following technical solution: a testing device for liquid crystal ion density in liquid crystal material preparation, including a spring wire, a handle fixedly connected to the bottom of the spring wire, a connecting block fixedly connected to the bottom end of the handle, and a mounting ring fixedly connected to the bottom end of the connecting block. It also includes a testing device, a fixing mechanism, a clamping mechanism, and a squeezing mechanism. The testing device is located at the output end of the spring wire and inside the connecting block. The fixing mechanism is movably located inside the mounting ring, and the fixing mechanism and the mounting ring are elastically connected. The clamping mechanism is located at the bottom end of the mounting ring, and its top is adapted to the inside of the mounting ring. The inside of the clamping mechanism is rotatably located at the bottom of the testing device. The squeezing mechanism is threaded onto the outer wall of the clamping mechanism, and the bottom of the clamping mechanism passes through the inside of the squeezing mechanism, with the bottom of the clamping mechanism contacting the inside of the squeezing mechanism.

[0007] Furthermore, the testing device includes a transmission rod and a connecting contact head. The transmission rod is slidably disposed inside the extrusion mechanism, and the outer diameter of the top of the transmission rod is larger than the inner diameter of the extrusion mechanism and smaller than the inner diameter of the mounting ring. The connecting contact head is installed inside the top of the connecting block, and the input end of the connecting contact head is connected to the output end of the spring wire.

[0008] Furthermore, the fixing mechanism includes a support spring, a movable ring, and a positioning rod. The mounting ring has two movable holes inside, which are arranged symmetrically in a circular array. The movable holes penetrate the outer and inner walls of the mounting ring, and the inner diameter of the middle of the movable hole is larger than the outer diameters on both sides. One end of the support spring is fixedly connected to the inner wall of the movable hole, and the other end is fixedly connected to the movable ring. The outer wall of the movable ring is adapted to the middle of the movable hole. The inner wall of the movable ring is fixedly connected to the positioning rod, which penetrates the interior of the movable hole.

[0009] Furthermore, the clamping mechanism includes a stud, an extension cylinder, and positioning holes. The stud is movably disposed at the bottom end of the mounting ring, and the extension cylinder is fixedly connected to the top end of the stud near the inside of the mounting ring. Two positioning holes are opened on the outer wall of the extension cylinder, and the two positioning holes are arranged symmetrically in a ring array.

[0010] Furthermore, it also includes a wire hole, a mounting hole, a movable groove, a rotating plate, a rubber pad, and a guide block. The wire hole is opened at the top of the stud, and the mounting hole is opened at the bottom of the stud. The mounting hole communicates with the wire hole. Two movable grooves are opened on the inner wall of the mounting hole. The two movable grooves are arranged symmetrically in a ring array. A rotating plate is rotatably connected to the inner wall of the movable groove. A rubber pad is fixedly connected to the inner side of the bottom of the rotating plate, and a guide block is fixedly connected to the outer side of the bottom of the rotating plate.

[0011] Furthermore, the extrusion mechanism includes a threaded cylinder and an extrusion ring. The inner wall of the threaded cylinder is threadedly connected to the outer wall of the clamping mechanism, and the extrusion ring is fixedly connected to the bottom of the inner wall of the threaded cylinder.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model uses a support spring to facilitate the movement of the positioning rod within the positioning hole, thereby enabling easy fixing or separation of the extension cylinder and the mounting ring. This allows for convenient replacement of the transmission rod. By rotating the threaded cylinder counterclockwise, the threaded cylinder drives the compression ring to compress the guide block. The guide block then drives the rotating plate to rotate within the movable groove. This allows the rotating plate to clamp and fix the outer wall of the transmission rod with a rubber pad, preventing the transmission rod from sliding up and down within the connecting block during worker movement. This protects the connecting contact head from indirect impacts during worker movement, which could damage the connecting contact head and affect the testing process. Attached Figure Description

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Appendix Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0022] See attached document Figures 1-5The liquid crystal ion density testing device for liquid crystal material preparation provided in this solution includes a spring wire 1, a handle 2 fixedly connected to the bottom of the spring wire 1, a connecting block 3 fixedly connected to the bottom of the handle 2, and a mounting ring 4 fixedly connected to the bottom of the connecting block 3. It also includes a testing device, a fixing mechanism, a clamping mechanism, and a squeezing mechanism. The testing device is located at the output end of the spring wire 1 and is situated inside the connecting block 3. The fixing mechanism is movably disposed inside the mounting ring 4, and the fixing mechanism and the mounting ring 4 are elastically configured. The clamping mechanism is located at the bottom of the mounting ring 4, and the top of the clamping mechanism is adapted to the interior of the mounting ring 4. The part is rotatably mounted at the bottom of the testing device. The extrusion mechanism is threaded onto the outer wall of the clamping mechanism. The bottom of the clamping mechanism passes through the interior of the extrusion mechanism and contacts the interior of the extrusion mechanism. Testing can be performed through the testing device. By moving the fixing mechanism to the outside of the mounting ring 4, the fixing mechanism can be released from the snap-fit ​​with the top of the clamping mechanism, which allows for easy replacement of the conductive parts in the testing device. The extrusion mechanism squeezes the clamping mechanism, which clamps and fixes the conductive parts in the testing device, preventing the conductive parts in the testing device from sliding up and down during the movement of the operator.

[0023] Specifically, the testing device includes a transmission rod 18 and a connecting contact head 19. The transmission rod 18 is slidably disposed inside the extrusion mechanism, and the outer diameter of the top of the transmission rod 18 is larger than the inner diameter of the extrusion mechanism and smaller than the inner diameter of the mounting ring 4. The connecting contact head 19 is installed inside the top of the connecting block 3, and the input end of the connecting contact head 19 is connected to the output end of the spring wire 1. The position of the transmission rod 18 can be easily moved through the spring wire 1. When the transmission rod 18 moves to the top of the connecting block 3 and contacts the connecting contact head 19, the transmission rod 18 can perform the transmission work.

[0024] Specifically, the fixing mechanism includes a support spring 6, a movable ring 7, and a positioning rod 8. Two movable holes 5 are formed inside the mounting ring 4, arranged symmetrically in a circular array. The movable holes 5 penetrate the outer and inner walls of the mounting ring 4, with the inner diameter of the middle portion of each hole larger than its outer diameter on both sides. One end of the support spring 6 is fixedly connected to the inner wall of the movable hole 5, and the other end is fixedly connected to the movable ring 7. The outer wall of the movable ring 7 is adapted to the middle portion of the movable hole 5. The inner wall of the movable ring 7 is fixedly connected to the positioning rod 8, which penetrates the interior of the movable hole 5. Due to the action of the support spring 6, after the positioning rod 8 moves outward from the movable hole 5 towards the outside of the mounting ring 4, the support spring 6 can drive the positioning rod 8 to reset.

[0025] Specifically, the clamping mechanism includes a stud 9, an extension cylinder 20, and positioning holes 21. The stud 9 is movably disposed at the bottom end of the mounting ring 4. The extension cylinder 20 is fixedly connected to the top of the stud 9 near the inside of the mounting ring 4. Two positioning holes 21 are opened on the outer wall of the extension cylinder 20, and the two positioning holes 21 are arranged symmetrically in a ring array. The outer wall of the positioning rod 8 is adapted to the inside of the positioning hole 21. When the extension cylinder 20 is embedded into the inside of the mounting ring 4, the positioning rod 8 is aligned with the positioning hole 21.

[0026] Specifically, it also includes a wire hole 10, a mounting hole 11, a movable groove 12, a rotating plate 13, a rubber pad 14, and a guide block 15. The wire hole 10 is opened at the top of the stud 9, and the mounting hole 11 is opened at the bottom of the stud 9. The mounting hole 11 communicates with the wire hole 10. Two movable grooves 12 are opened on the inner wall of the mounting hole 11. The two movable grooves 12 are arranged symmetrically in a ring array. The rotating plate 13 is rotatably connected to the inner wall of the movable groove 12. The rubber pad 14 is fixedly connected to the inner side of the bottom of the rotating plate 13, and the guide block 15 is fixedly connected to the outer side of the bottom of the rotating plate 13. When the outer wall of the two guide blocks 15 is squeezed by the squeezing mechanism, the inclined surface on the outer side of the guide block 15 causes the guide block 15 to drive the rotating plate 13 to rotate inside the movable groove 12. This allows the rotating plate 13 to drive the rubber pad 14 to clamp and fix the outer wall of the transmission rod 18, so that the transmission rod 18 will not slide up and down inside the connecting block 3 during the movement of the staff.

[0027] Specifically, the extrusion mechanism includes a threaded cylinder 16 and an extrusion ring 17. The inner wall of the threaded cylinder 16 is connected to the outer wall of the clamping mechanism by threads, and the extrusion ring 17 is fixedly connected to the bottom of the inner wall of the threaded cylinder 16. The inner wall of the threaded cylinder 16 is connected to the outer side of the stud 9, and the inner wall of the extrusion ring 17 is in contact with the inclined surface on the outer side of the two guide blocks 15.

[0028] The working principle and usage process of this utility model are as follows: During use, the positioning rod 8 can be moved outwards from the mounting ring 4, causing the positioning rod 8 to move the movable ring 7 inside the moving hole 5. At this time, the movable ring 7 compresses the support spring 6, thus moving one end of the positioning rod 8 from inside the positioning hole 21 to inside the moving hole 5, thereby releasing the restriction on the extension cylinder 20. Pulling the stud 9 causes the stud 9 to pull the extension cylinder 20 out of the mounting ring 4, which in turn pulls the transmission rod 18, causing the transmission rod 18 to separate the stud 9 from the mounting ring 4, facilitating replacement of the transmission rod 18. When the positioning rod 8 is embedded in the positioning hole 21, and when not using the transmission rod 18 for testing, rotating the threaded cylinder 16 counterclockwise causes the threaded cylinder 16 to drive the compression ring 17 to compress the guide block 15. Because the guide block 15 is outside... The inclined surface on the side allows the guide block 15 to drive the rotating plate 13 to rotate inside the movable groove 12. This allows the rotating plate 13 to drive the rubber pad 14 to clamp and fix the outer wall of the transmission rod 18, so that the transmission rod 18 will not slide up and down inside the connecting block 3 during the movement of the staff. This protects the connecting contact head 19 and prevents the transmission rod 18 from indirectly colliding with the connecting contact head 19 during the movement of the staff. This process can easily damage the connecting contact head 19 and affect the testing process. When using the transmission rod 18, rotating the threaded cylinder 16 clockwise can release the compression ring 17 from the compression of the guide block 15, thereby releasing the restriction on the transmission rod 18. When the transmission rod 18 is tested, it moves upward and makes contact with the connecting contact head 19 to carry out the transmission operation.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its scope of protection shall still fall within the protection scope of this utility model.
