DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0026] Reference Figure 1-5 , a pressure-maintaining fixture, comprising:

[0027] A pedestal 1, a gantry 2 is fixedly arranged on the top of the pedestal 1, a sliding frame 3 is slidably arranged outside the gantry 2, a connecting frame 4 is slidably arranged inside the sliding frame 3, a fixing frame 7 is fixedly arranged on one side of the connecting frame 4, a jig upper die 23 is fixedly arranged on the bottom of the fixing frame 7, and a jig lower die 22 is placed on the top of the pedestal 1;

[0028] An adjustment component is disposed on the pedestal 1 and is used to adjust the working height of the upper mold 23 of the jig;

[0029] The clamping assembly is arranged on the pedestal 1 and is used to clamp the lower mold 22 of the fixture.

[0030] The above technical solution can achieve the purpose of adjusting the height of the jig upper mold 23 by setting the adjustment component, so that the jig upper mold 23 is located at the optimal working height, so that the device can adapt to jigs of different heights. The jig can be clamped and fixed by setting the clamping component to prevent it from moving during the processing process, resulting in deviation in the position of the jig and affecting the quality of pressure holding. At the same time, jigs of different sizes and shapes can be fixed and clamped, so that the device is suitable for various types of jigs, providing a wider range of applications. The jig lower mold 22 is matched with the jig upper mold 23. The base 1 is provided with an electric push rod 21 control switch and a temperature control switch. The jig upper mold 23 and the jig lower mold 22 can be connected to the temperature control switch through a connecting line. Turning the temperature control switch can electrically heat the jig upper mold 23 and the jig lower mold 22.

[0032] The above technical solution can be achieved by setting the threaded rod 6 and the knob 5. When facing jigs of different thicknesses, the knob 5 is turned. The rotation of the knob 5 drives the threaded rod 6 to rotate at the same time. The rotation of the threaded rod 6 can drive the sliding frame 3 and the upper parts thereof to rise synchronously, thereby adjusting the height of the jig upper mold 23. The jig upper mold 23 can be located at the optimal working height, so that the device can adapt to jigs of different heights. The setting of the nut can play a role in limiting the connecting frame 4. The threaded rod 6 idles inside the connecting frame 4 during the rotation process, so that the threaded rod 6 will not drive the connecting frame 4 to move when it rotates.

[0033] Reference Figure 5 The clamping assembly includes four slide grooves 14 which are cross-shaped and respectively opened on the top of the pedestal 1. Clamp blocks 15 are slidably arranged inside the four slide grooves 14. A cavity is arranged inside the pedestal 1. Slide plates 19 are fixedly arranged at the bottom of the four clamp blocks 15 located in the cavity of the pedestal 1. The four slide plates 19 are slidably connected to the top wall of the cavity of the pedestal 1. A fixing column 16 is fixedly arranged inside the cavity of the pedestal 1. A rotating plate 17 is rotatably arranged outside the fixing column 16. Fixed rods are arranged on the four sides of the top of the rotating plate 17, and linkage rods 18 are movably arranged on the outside of the four fixing rods. The four linkage rods 18 are fixedly connected to the bottom of the slide plates 19 by bolts. A mounting frame 20 is fixedly arranged at the bottom of a group of two symmetrical slide plates 19.

[0037] The above technical scheme can be achieved by setting the gear 11, the rotating rod 10 and the rack 8. The operator holds the operating rod 13 and presses it downward at a uniform speed. When the operating rod 13 is pressed, the rotating rod 10 is driven to rotate on the support frame 9. When the rotating rod 10 rotates, the gear 11 is driven to rotate synchronously. When the gear 11 rotates, it drives the rack 8 meshing with it to move downward. When the rack 8 moves downward, it drives the connecting frame 4 to move downward inside the sliding frame 3. When the connecting frame 4 moves downward, it drives the upper mold 23 of the jig to approach the lower mold 22 of the jig, thereby maintaining the pressure of the earphone cover. When the operating rod 13 is pressed, the reset spring 12 is deformed by the force, which can buffer the force of the upper mold 23 of the jig when it is pressed. After the pressure maintenance is completed, the force pressing the operating rod 13 is released, and then the connecting frame 4 is pushed up by the elastic principle of the reset spring 12 itself, thereby driving the upper mold 23 of the jig to reset, so as to carry out the next pressure maintenance.

[0038] Reference Figure 1-3 One end of the rotating rod 10 rotates and passes through one of the supporting frames 9 and extends to the outside. A plug-in column is fixed to one end of the rotating rod 10 located outside the supporting frame 9, and an operating rod 13 is fixed to the outside of the plug-in column.

[0039] The above technical solution can achieve the goal of pressing and maintaining the earphone cover by setting the operating rod 13. The operator holds the handle 14 and presses it downward at a constant speed. An anti-slip cover is provided on the operating rod 13 to increase the friction between the operator's hand and the operating rod 13, preventing the operator's hand from slipping and detaching from the operating rod 13 during the pressing process, which would affect the pressure maintenance work.

[0040] Reference Figure 2 A power switch 24 is disposed on the rear side of the pedestal 1 , and a power connection port is disposed next to the power switch 24 .

[0041] The above technical solution can achieve electrical connection between the power switch 24 and the electric push rod 21. By setting the power switch 24, the opening and closing of the electric push rod 21 can be controlled. When an unexpected situation occurs, a timely response can be made. By setting the power connection port, it is convenient to connect the device to the power supply.

[0042] However, as is well known to those skilled in the art, the working principles and wiring methods of the electric push rod 21, the upper mold 23 and the lower mold 22 are commonplace, and are conventional means or common knowledge, and will not be elaborated here.
