DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Referring to Figures 1-3 , a measurement interface component for a logic analyzer, comprising:

[0021] An analyzer 1 is provided with a plurality of interfaces on one side thereof. A protective housing 2 is provided on the outer side of each interface, and the protective housing 2 is fixedly connected to the side wall of the analyzer 1. A fixed shaft 3 is rotatably connected between the inner walls of each protective housing 2. A fixing plate 4 is fixedly sleeved on each fixed shaft 3. The protective housing 2 protects the interfaces, preventing dust and other debris from falling onto the interfaces and affecting the use of the interfaces.

[0022] A fixing structure, the fixing structure includes fixing grooves 8 opened on each fixing plate 4. A connecting plate 9 is fixedly connected to the inner wall of each fixing groove 8. An installation plate 10 is provided on each connecting plate 9. A clamping plate 11 is fixedly connected to one end of each installation plate 10 away from the connecting plate 9. An adjusting structure is provided on the protective housing 2. After the fixing plate 4 is opened, the connector is inserted into the interface. At this time, the installation plate 10 pushes the clamping plate 11 to move, so that the clamping plate 11 clamps both sides of the connector, thereby ensuring the stability of the wiring.

[0023] The adjusting structure includes an adjusting plate 7 provided below the protective housing 2. The bottom ends of each fixed shaft 3 respectively penetrate through the corresponding protective housing 2 and extend to the outside of the protective housing 2. A fixed cavity 12 is opened inside each protective housing 2. A spiral groove is provided on the inner wall of each fixed cavity 12. Each fixed cavity 12 is slidably connected with a sliding plate 13 through the spiral groove. The bottom end of each sliding plate 13 is fixedly connected with an adjusting rod 6. Each adjusting rod 6 respectively penetrates through the lower inner wall of the corresponding fixed cavity 12 and extends to the outside of the fixed shaft 3. The bottom ends of each adjusting rod 6 are respectively fixedly connected to the corresponding adjusting plate 7. Push the adjusting plate 7 to move it upward. When the adjusting plate 7 moves, the adjusting rod 6 moves accordingly, driving the sliding plate 13 to move. Under the action of the spiral groove, when the sliding plate 13 moves, the fixed shaft 3 will rotate.

[0024] A return spring 14 is fixedly connected to the top end of each sliding plate 13. One end of each return spring 14 away from the sliding plate 13 is respectively fixedly connected to the upper inner wall of the corresponding fixed cavity 12. When the sliding plate 13 moves upward, the return spring 14 will contract, and the elastic force of the return spring 14 will make the sliding plate 13 return to its original position, thereby driving the fixed shaft 3 to rotate.

[0025] A torsion spring 5 is sleeved on the outer side of each fixed shaft 3. One end of each torsion spring 5 is fixedly connected to the inner wall of the protective housing 2, and the other end of each torsion spring 5 is fixedly connected to the outer wall of the corresponding fixing plate 4. When the fixed shaft 3 rotates, the torsion spring 5 will deform, and the elastic force generated by the deformation of the torsion spring 5 can facilitate the fixed shaft 3 to return to its original position;

[0026] Each connecting plate 9 and the corresponding mounting plate 10 are elastically slidably connected. An installation spring is arranged between the connecting plate 9 and the mounting plate 10, and the elastic force of the installation spring causes the mounting plate 10 to move outward; Rounding corners are provided on the side walls of each clamping plate 11 to prevent the clamping plate 11 from being scratched and damaged when it comes into contact with the joint.

[0027] In the present utility model, when the device is in use, first push the adjusting plate 7 to move it upward. When the adjusting plate 7 moves, the adjusting rod 6 moves accordingly, driving the sliding plate 13 to move, causing the return spring 14 to contract. Under the action of the spiral groove, when the sliding plate 13 moves, it will cause the fixed shaft 3 to rotate. When the fixed shaft 3 rotates, it will drive the fixing plate 4 to rotate, and the torsion spring 5 deforms, opening the protective housing 2 to expose the interface. Insert the joint into the interface. At this time, the joint and the clamping plate 11 press against each other, causing the spring to contract. Under the action of the spring elastic force, the clamping plate 11 clamps both sides of the joint, thus ensuring the stability of the wiring. After the joint is removed, the elastic force of the return spring 14 pushes the sliding plate 13 to move back, causing the fixed shaft 3 to rotate in the reverse direction. At the same time, the spring force of the torsion spring 5 can assist the reset of the fixed shaft 3, causing the fixing plate 4 to return to its original position and closing the protective housing 2 to prevent dust and other debris from falling onto the interface and affecting the use of the interface.

[0028] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
