As shown in fig. 1 to 7, a pressure holding mechanism according to an embodiment of the present invention includes a main body 1, a plunger assembly 2, and a positioning rod assembly 3. Wherein the main body 1 has a first through hole 11 and a second through hole 12, the first through hole 11 and the second through hole 12 are perpendicular to each other, and the first through hole 11 and the second through hole 12 communicate with each other. The pressing rod assembly 2 is movably installed in the first through hole 11 and comprises a limiting portion 21 and a pressing rod 22, and the limiting portion 21 is located in the middle of the pressing rod 22. The positioning rod assembly 3 is movably installed in the second through hole 12 and includes a positioning rod 32 and a positioning member 31, the positioning member 31 is located in the middle of the positioning rod 32 and is used for cooperating with the limiting portion 21 to position the pressure rod assembly 2. Before exerting pressure to the product, the pressure maintaining mechanism is in a reset state, and at this time, the positioning rod assembly 3 is located at the lowest end of the limiting portion 21, and the positioning member 31 can move upward relative to the limiting portion 21. When the product is pressed, the pressing rod assembly 2 is pressed down, so that the pressing rod assembly 2 moves downwards relative to the main body 1 in the first through hole 11 until the lower end of the pressing rod 22 presses the product; at the in-process that depression bar assembly 2 removed, locating lever assembly 3 keeps relative still with main part 1, consequently pushes down to the biggest stroke at depression bar assembly 2, and locating lever assembly 3 moves to spacing portion 21 the top just, and through to main part 1 side lateral shifting locating lever assembly 3 this moment, can make setting element 31 and spacing portion 21 form the joint to make depression bar assembly 2 can not upwards kick-back, realize the pressurize effect. When needs reset, press down locating lever 32 to main part 1 direction, make setting element 31 and spacing portion 21's joint part separately, then can realize resetting with depression bar subassembly 2 rebound. The embodiment realizes the position fixation of the pressing rod assembly 2 after pressing down in the above way, thereby utilizing the pressing rod 22 to apply pressure to the product for effective pressure maintaining, fixing or testing, and ensuring the production quality of the product.

In a specific embodiment, the position-limiting portion 21 includes a bar-shaped hole 211 and a position-limiting hole 212. The opening direction of the bar-shaped hole 211 is parallel to the second through hole 12, and the extending direction is parallel to the first through hole 11. The limiting hole 212 is disposed at one end of the bar-shaped hole 211, and the diameter of the limiting hole 212 is larger than the width of the bar-shaped hole 211. The positioning piece 31 and the limiting part 21 are matched through the strip-shaped hole 211 and the limiting hole 212, when in a reset state, the positioning rod 32 passes through the strip-shaped hole 211, and the positioning piece 31 is positioned on one side of the strip-shaped hole 211, so that the positioning rod assembly 3 can move along the strip-shaped hole 211; when the pressing rod assembly 2 is pressed down, the positioning rod assembly 3 moves along the bar-shaped hole 211 until the positioning rod 32 moves into the limiting hole 212, and then the positioning member 31 enters the limiting hole 212 to be positioned by moving the positioning rod assembly 3 transversely.

In a specific embodiment, the diameter of the positioning rod 32 is smaller than the width of the strip-shaped hole 211, and the positioning member 31 is shaped and sized to fit the limiting hole 212 and is configured to move into the limiting hole 212 to position the compression bar assembly 2. Because the diameter of spacing hole 212 is greater than the width of bar hole 211, and setting element 31 matches with spacing hole 212 size and shape, consequently the setting element 31 just can not remove along bar hole 211 after getting into spacing hole 212, consequently can realize fixing the depression bar subassembly 2 through the cooperation of setting element 31 with spacing hole 212 to realize the pressurize.

In some optional embodiments, one end of the first through hole 11 is provided with a first step 111, the diameter of the limiting portion 21 is larger than that of the pressing rod 22, the pressing rod 22 is sleeved with a pressing rod spring 23, and two ends of the pressing rod spring 23 are respectively abutted against the first step 111 and the limiting portion 21. In the process of pressing in the above-described manner, the plunger spring 23 disposed between the first step 111 and the stopper portion 21 is compressed, thereby generating an upward elastic force to the stopper portion 21. When resetting, the positioning rod assembly 3 is pressed down, so that after the positioning piece 31 is disengaged from the limiting hole 212, the limiting part 21 and the pressing rod 22 can automatically reset under the action of the elastic force of the pressing rod spring 23, and the pressure maintaining mechanism is more convenient to use.

In some alternative embodiments, the strut assembly 2 further includes a press block 24. The pressing block 24 is fixedly installed at one end of the pressing rod 22 close to the first step 111, and is used for pressing the product, increasing the contact area of the pressing rod 22 when pressing the product, and achieving a better pressing effect.

In some alternative embodiments, the main body 1 is further provided with a guide hole 16 on a side close to the pressing block 24, the guide hole 16 extends in a direction parallel to the first through hole 11, a guide 241 is fixedly mounted on a side of the pressing block 24 close to the main body 1, and the guide 241 forms a clearance fit with the guide hole 16. When the pressure lever 22 moves up and down relative to the main body 1, the pressing block 24 also moves up and down relative to the main body 1, in the process, the guide piece 241 on the pressing block 24 moves in the guide hole 16, the guide piece 241 is in clearance fit with the guide hole 16, the movement of the pressure lever assembly 2 is guided, the movement direction of the pressure lever assembly 2 is limited, and the work of the pressure maintaining mechanism is more stable.

In some alternative embodiments, the pressing block 24 further comprises a cushion 242 fixedly mounted on a surface of the pressing block 24 on a side away from the main body 1. The cushion pad 242 is made of soft material such as high-strength rubber or rubber, and can play a role in buffering when pressing the product, thereby avoiding surface abrasion or structural damage to the product when pressing the product.

When the pressure retention mechanism is in the reset state, the detent lever spring 33 is in the compressed state, and the detent lever spring 33 applies an elastic force to the detent member 31 to the outside of the main body 1, but since the shape and size of the detent member 31 are adapted to the stopper hole 212, the diameter of the detent member 31 is larger than the width of the bar-shaped hole 211, and therefore the detent member 31 cannot pass through the bar-shaped hole 211, and the detent lever spring 33 can continuously maintain the compressed state in the reset state. When the pressure maintaining mechanism applies pressure according to the above manner, the pressure lever assembly 2 is pressed down, so that when the positioning rod 32 moves into the limiting hole 212, the positioning member 31 located beside the limiting hole 212 automatically enters the limiting hole 212 under the elastic force of the positioning rod spring 33, thereby positioning the pressure lever assembly 2.
