DETAILED DESCRIPTION

[0023] The utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0024] In this embodiment, refer to Figures 1-7 A screen pressure maintaining jig capable of being quickly disassembled, comprising a support 1 and a slidable mounting plate 2, the support 1 is provided with a driving member 11 connected and matched with the mounting plate 2, one end of the support 1 and the mounting plate 2 is respectively provided with a concave die 12 and a convex die 21 matched with each other, one end of the concave die 12 and the convex die 21 is provided with a fixing pin 3, one end of the support 1 and the mounting plate 2 is provided with a clamping assembly 4, one end of the clamping assembly 4 is provided with a reference hole 411 matched with the fixing pin 3, and the concave die 12 is provided with a stripping assembly 5. The driving member 11 provided on the support 1 enables the mounting plate 2 to reciprocally slide along the support 1, thereby driving the convex die 21 to open and close relative to the concave die 12. Thus, screen pressure maintaining and disassembling operations are completed. Meanwhile, through the cooperation of the fixing pin 3, the reference hole 411 and the clamping assembly 4, the concave die 12 and the convex die 21 can be accurately and quickly positioned and fixed on the support 1 and the mounting plate 2. And through the stripping assembly 5 provided in the concave die 12, the screen can be easily ejected from the concave die 12 after pressure maintaining is completed, thereby quickly separating from the concave die 12.

[0025] The one end of the male die 21 is provided with a protrusion 211 matched with the female die 12, the female die 12 is provided with a recess 121 and a mobile phone slot 122 matched with the protrusion 211, and the mobile phone slot 122 is arranged in the mobile phone slot 122. The depth of the mobile phone slot 122 is lower than the thickness of the mobile phone. The protrusion 211 is made of elastic plastic material. When the male die 21 is matched with the female die 12, the protrusion 211 is matched with the recess 121, and is in close contact with the mobile phone screen arranged in the mobile phone slot 122. In the pressure maintaining process of the mobile phone screen, the protrusion 211 made of elastic plastic material can provide certain buffering effect, so as to avoid excessive pressure on the mobile phone screen, thereby protecting the mobile phone screen from being damaged. At the same time, since the depth of the mobile phone slot 122 is lower than the thickness of the mobile phone, when the mobile phone screen is arranged in the mobile phone slot 122, the edge part of the mobile phone screen is higher than the edge of the mobile phone slot 122. Therefore, when the male die 21 is closed with the female die 12, the protrusion 211 can better contact with the edge part of the mobile phone screen, thereby improving the pressure maintaining effect.

[0026] In addition, the support 1 and the mounting plate 2 are respectively provided with a plurality of limiting holes, the female die 12 and the male die 21 are respectively provided with limiting shafts matched with the limiting holes, and the angle of the female die 12 and the male die 21 is adjusted through the cooperation of the limiting shafts and the limiting holes, so as to ensure that the female die 12 and the male die 21 can maintain accurate positional relationship when matched, and further improve the assembly accuracy of the pressure maintaining jig.

[0027] The support 1 and the mounting plate 2 are respectively provided with a plurality of limiting holes, the female die 12 and the male die 21 are respectively provided with limiting shafts matched with the limiting holes, and the angle of the female die 12 and the male die 21 is adjusted through the cooperation of the limiting shafts and the limiting holes, so as to ensure that the female die 12 and the male die 21 can maintain accurate positional relationship when matched, and further improve the assembly accuracy of the pressure maintaining jig.

[0028] The first through hole 61 and the second through hole 62 are respectively arranged at two ends of the sealing cavity 6, so that the piston 42 reciprocates in the sealing cavity 6, thereby enabling the fixed blocks 43 to be matched with the fixed grooves 31 on the fixed pin 3, and the quick clamping and loosening operation is completed. The mounting block 41 and the piston 42 are respectively provided with sealing rings matched with the sealing cavity 6, so as to ensure that the gas pressure or hydraulic pressure in the sealing cavity 6 is stable, and the gas or liquid leakage is avoided, thereby affecting the normal work of the clamping assembly 4.

The design of the spherical or columnar structure makes the sliding of the fixed block 43 in the mounting hole 412 more flexible, which can better adapt to the clamping requirements of different angles and directions. When the piston 42 slides in the sealing cavity 6, the guide structure 421 guides the fixed block 43 to move along a predetermined path, ensuring that the fixed block 43 can accurately and quickly cooperate with the fixed groove 31 on the fixed pin 3 to complete the clamping action. In addition, the spherical or columnar structure of the fixed block 43 can also reduce the friction between the fixed block 43 and the mounting hole 412, prolonging the service life of the clamping assembly 4.

Through the setting of the compression spring, the mounting plate 2 can be elastically supported during the sliding process, further improving the stability and precision of the sliding. At the same time, when the punch 21 and the die 12 are opened and closed, the compression spring can provide a certain buffering effect, reducing the impact and vibration in the opening and closing process, thereby protecting the components of the jig from being damaged and prolonging the service life of the jig.

[0033] One end of the male die 21 is provided with a plurality of positioning pins 212, and the female die 12 is provided with positioning holes 123 matched with the positioning pins 212.
