Description
Technical Field
[0001] This utility model relates to the field of electrical testing tooling technology, and in particular to a press-to-unlock handle for electrical testing tooling. Background Technology
[0002] During the use of electrical testing fixtures, locking and unlocking mechanisms are necessary to ensure the stability of the testing process and ease of operation. Traditional electrical testing fixture locks mostly adopt knob-type or snap-on structures, which have problems such as cumbersome operation and insufficient locking stability.
[0003] Rotary locks require multiple rotations to lock or unlock, which is inefficient in high-frequency operation scenarios. Furthermore, prolonged use can lead to thread wear and locking failure. While snap-locks are faster to operate, the fit between the snap and the slot requires high precision. Repeated insertion and removal can cause deformation, resulting in loosening of the lock or difficulty in unlocking, affecting the positioning accuracy of electrical testing fixtures.

[0004] To address the technical problems existing in the background art, this utility model proposes a press-to-unlock handle for electrical testing fixtures.
[0005] This utility model proposes a press-to-unlock handle for electrical testing fixtures, including a mounting base, a shaft rotatably connected inside the mounting base, one end of the shaft being connected to a lock, and the other end being symmetrically connected to the electrical testing fixtures; The lock includes a second seat block mounted on the side of the mounting base and a first seat block mounted on the side of the second seat block. A handle is rotatably connected between the first and second seat blocks. The end of the shaft passes through the second seat block and connects to the handle. The inner sides of the first and second seat blocks are provided with interconnected guide grooves and locking grooves. A cavity is provided inside the handle. A pressing rod is slidably connected inside the cavity. The bottom of the pressing rod is connected to a first pin. Both ends of the first pin extend to the outside of the handle and slide inside the guide groove and locking groove. A spring is provided at the bottom of the cavity, and the spring abuts against the pressing rod.
[0006] Furthermore, the first and second base blocks each have a first shaft hole inside, the bottom of the handle has a second shaft hole, and the end of the shaft passes through the first shaft hole and is fixedly connected to the second shaft hole.
[0007] Furthermore, a pin hole is provided at the bottom of the handle. The pin hole is an oblong hole. A second pin hole is provided at the bottom of the pressure rod. The first pin is fixed inside the second pin hole, and both ends of the first pin extend to the outside of the handle through the pin hole.
[0008] Furthermore, the top of the pressure rod extends to the outside of the cavity and is connected to the pressure head.
[0009] Furthermore, the locking groove is located at both ends of the guide groove, and the guide groove has an arc-shaped structure and is coaxial with the shaft.
[0010] Furthermore, the electrical testing fixture includes a fixture base rotatably connected to the shaft, a connecting member rotatably connected to the side of the fixture base, the shaft being fixedly connected to the connecting member, and a swing arm rotatably connected to the upper part of the connecting member.
[0011] Furthermore, a guide rod is slidably connected inside the tooling base, the top of the guide rod is connected to a lifting seat, the side of the lifting seat is connected to a protruding post, and the protruding post is rotatably connected to the top of the swing arm.
[0012] The beneficial effects of this utility model are as follows: By setting a spring-reset touch rod in the lock, which cooperates with the first pin shaft guide groove and locking groove, the function of unlocking by pressing and automatically locking after rotation adjustment is realized. This simplifies the unlocking operation steps of the electrical testing fixture, improves the efficiency in high-frequency operation scenarios, and ensures the stability of the locked state through the precise cooperation between the locking groove and the first pin shaft.

[0015] Reference Figure 1-6 This utility model proposes a push-to-unlock handle for an electrical testing fixture, comprising a mounting base 1. Inside the mounting base 1, a shaft 3 is rotatably connected. The shaft 3 is responsible for power transmission. One end of the shaft 3 is connected to a lock 2 for controlling locking and unlocking, and the other end is symmetrically connected to the electrical testing fixture 4. The rotation of the shaft 3 can drive the electrical testing fixture 4 to complete the action adjustment. The specific technical solution is as follows: Lock 2 mainly consists of a first seat block 21, a second seat block 22, a handle 24, a pressing rod 211, a spring 28, and a first pin 26. The second seat block 22 is fixedly installed on the side of the mounting base 1, and the first seat block 21 is installed on the side of the second seat block 22. Both have a first shaft hole 23 inside. The bottom end of the handle 24 has a second shaft hole 214. The end of the shaft 3 passes through the first shaft hole 23 and is fixedly connected to the second shaft hole 214, so that the handle 24 can rotate around the shaft through the shaft 3. A cavity 27 is opened inside the handle 24. The pressing rod 211 is slidably connected in the cavity 27, and its top end extends to the outside of the cavity 27 and is connected to a pressure head 213 for easy pressing operation by the operator. A first pin 26 is opened at the bottom. The first pin 26 is fixed in the second pin hole 212, and the bottom of the handle 24 is provided with an elongated pin hole 25. The two ends of the first pin 26 extend to the outside of the handle 24 through the pin hole 25. A spring 28 is provided at the bottom of the cavity 27. The spring 28 abuts against the touch rod 211 and provides an upward reset force for the touch rod 211. The inner sides of the first seat block 21 and the second seat block 22 are provided with a connected guide groove 29 and a locking groove 210. The locking groove 210 is located at both ends of the guide groove 29. The guide groove 29 has an arc structure and is coaxial with the shaft 3. The two ends of the first pin 26 can slide in the guide groove 29 and the locking groove 210 to realize the locking and unlocking guidance of the handle 24. The electrical testing fixture 4 consists of a fixture base 41, a connector 42, a swing arm 43, a guide rod 44, a lifting seat 45, and a protruding column 46. The fixture base 41 is rotatably connected to the shaft 3, providing stable support for the entire electrical testing fixture. The connector 42 is rotatably connected to its side, and the shaft 3 is fixedly connected to the connector 42, ensuring that the shaft 3 can drive the connector 42 to rotate synchronously when it rotates. The upper part of the connector 42 is rotatably connected to the swing arm 43. The guide rod 44 is slidably connected inside the fixture base 41. The top of the guide rod 44 is connected to the lifting seat 45. The side of the lifting seat 45 is connected to the protruding column 46. The protruding column 46 is rotatably connected to the top of the swing arm 43. When the swing arm 43 swings with the connector 42, the lifting seat 45 can be driven to slide up and down along the guide rod 44 through the protruding column 46. Work process: Under the natural elastic force of spring 28, the contact rod 211 is in the upper position, and the first pin 26 is engaged in the locking groove 210 at the end of the guide groove 29. At this time, the handle 24 cannot rotate, and the electrical testing fixture 4 is in the initial stable state (the lifting seat 45 is in the lowered position, such as...). Figure 6 (as shown) The operator presses down on the pressure head 213, causing the pressure rod 211 to slide downwards along the cavity 27 and compress the spring 28. The first pin 26 moves down along the elongated pin hole 25 and slides from the locking groove 210 into the guide groove 29, completing the unlocking action. After unlocking, the handle 24 is rotated, and the handle 24 drives the connecting piece 42 to rotate synchronously through the shaft 3. The connecting piece 42 drives the swing arm 43 to swing. The top of the swing arm 43 drives the lifting seat 45 to slide up and down along the guide rod 44 through the protrusion 46, realizing the height adjustment of the electrical testing fixture (e.g., ...). Figure 5 The image shows the lifting seat in the raised position (45). After adjusting to the target position, release the pressure head 213. The pressure rod 211 returns to its original position under the elastic force of the spring 28. The first pin 26 slides from the guide groove 29 into the corresponding locking groove 210. The handle 24 locks again, and the electrical testing fixture is stabilized in the adjusted position.
