As shown in fig. 3 to 5 and 11, the first frame 10 and the second frame 30 define an accommodating space 40 together, the accommodating space 40 extends along the first direction D1, the air exhaust channel 11 of the first frame 10 communicates the accommodating space 40 and the outside of the first frame 10, the attachment layer 20 is located in the accommodating space 40, and divides the accommodating space 40 into a first air exhaust channel 41 adjacent to the first frame 10 and a second air exhaust channel 42 adjacent to the second frame 30, and the first air exhaust channel 41 and the second air exhaust channel 42 are communicated through the through hole 21 of the attachment layer 20.

The utility model discloses frame construction's first frame 10 and second frame 30 combine by the subsides of attached layer 20, bleed to the pumping channel 11 of first frame 10 through outside vacuum apparatus, enable the gas that is arranged in the second exhaust passage 42 between attached layer 20 and second frame 30, through the through hole 21 of attached layer 20 and lead to the first exhaust passage 41 between attached layer 20 and the first frame 10, gas in the first exhaust passage 41 can be derived to the outside from pumping channel 11, thereby can take out remaining gas between first frame 10 and second frame 30 and the attached layer 20, in addition, accommodation space 40 with pumping channel 11 intercommunication also can produce the negative pressure, make attached layer 20 begin to produce deformation and stop up the pumping channel 11, make accommodation space 40 present the vacuum state, and utilize the auxiliary fixation of vacuum power, therefore first frame 10 and second frame 30 can more closely contact with attached layer 20 and paste, and increase the attached area and the attached integrality of layer 20 by reducing remaining gas, consequently, first frame 10 and second frame 30 closely combine the adhesion strength in order to promote the adhesion of frame closely, thereby the risk of more closely combining and avoiding the adhesion of frame to peel off. In addition, the adhesive layer 20 is preferably a flexible and deformable adhesive tape.

By the design that the through hole 21 and the pumping channel 11 are at least partially overlapped, the second exhaust channel 42 can be communicated with the pumping channel 11 through the through hole 21, when the attachment layer 20 is concavely attached to the first frame 10 under the influence of vacuum suction, residual gas between the second frame 30 and the attachment layer 20 can still be pumped out from the pumping channel 11 through the through hole 21, thereby improving the bonding strength of the second frame 30 and the attachment layer 20, preferably, as shown in fig. 3 and 5, the diameter of the through hole 21 is larger than that of the pumping channel 11, so that when a worker bonds and combines the attachment layer 20 and the first frame 10, the alignment between the through hole 21 and the pumping channel 11 is facilitated, the convenience of assembling the frame structure is improved, and the through hole 21 can preferably completely cover the opening of the pumping channel 11, so that the communication between the second exhaust channel 42 and the pumping channel 11 can be still ensured when the attachment layer 20 is adsorbed and deformed by vacuum suction. Moreover, when the negative pressure is generated during air suction, the flow path of the air flows from the large aperture to the small aperture, and the sectional area of the air suction channel 11 is suddenly reduced, so that the pressure value is also suddenly reduced, and further the gas flow speed is accelerated, so that the air can be smoothly sucked out from the air suction channel 11, and the effect of blocking the flow is not easily generated.

Preferably, the first frame 10 has a plurality of pumping channels 11, and the adhesive layer 20 has a plurality of through holes 21, so as to improve the exhaust efficiency. Furthermore, the air exhaust channel 11 is linear or curved, as long as two ends of the air exhaust channel 11 are respectively communicated with the accommodating space 40 and the outside of the first frame 10, so that the air exhaust channel 11 can exhaust the air in the accommodating space 40.

As shown in fig. 6, 9 and 10, the second frame 30 has a groove 31 disposed on a side facing the first frame 10, the groove 31 extends along the first direction D1, the groove 31 is communicated with the second exhaust channel 42, and the residual gas between the second frame 30 and the adhesive layer 20 can be exhausted along the groove 31 by disposing the groove 31, so as to improve the exhaust efficiency of the residual gas. The first frame 10 has a groove 13 disposed on a side facing the second frame 30, the groove 13 extends along the first direction D1 and is communicated with the pumping channel 11, at least a portion of the adhesive layer 20 is located in the groove 13, and the first exhaust channel 41 is communicated with the groove 13. When the air is pumped to generate negative pressure, since the grooves 13 and the grooves 31 extend along the first direction D1, the air can flow along the first direction D1 toward the middle position between the grooves 13 and the grooves 31, and then is exhausted along the second direction D2 through the air pumping channel 11, so that the air exhausting efficiency can be increased by the grooves 13 and the grooves 31.

Therefore, the air circulation effect is also provided at the end of the air escape groove 32 away from the groove 31, which is also beneficial to increase the additional adhesion force.

Furthermore, as shown in fig. 6 to 8, the cross section of the air escape groove 32 is changed by changing the width W or height H of the cross section of the air escape groove 32, in the embodiment of the present invention, the width W of the cross section of the air escape groove 32 is parallel to the first direction D1, and the height H of the cross section of the air escape groove 32 is parallel to the second direction D2, preferably, as shown in fig. 7, the width W of the side of the air escape groove 32 away from the groove 31 is smaller than the width W of the side of the air escape groove 31, and as shown in fig. 8, the height H of the side of the air escape groove 32 away from the groove 31 is smaller than the height H of the side of the air escape groove 31, so as to improve the gas discharging efficiency of the air escape groove 32, and as long as one of the width W or height H of the cross section of the air escape groove 32 conforms to the condition that the side of the air escape groove 31 is larger and the side of the air escape groove 31 is smaller, the effect of improving the gas discharging efficiency can be achieved.

In addition, due to the design of the grooves 13 and the grooves 31, the first frame 10 and the second frame 30 are not adhered in a planar manner, but are adhered in a planar manner, so that the adhering area of the adhering layer 20 can be increased, and the adhering strength can be improved. Preferably, the groove 13 of the first frame 10 and the groove 31 of the second frame 30 are overlapped along the second direction D2, that is, the groove 13, the through hole 21 of the adhesive layer 20 and the groove 31 are directly connected along the second direction D2, so that the gas can be smoothly introduced into the groove 13 when moving along the groove 31 to increase the smoothness of gas exhaust and improve the efficiency of residual gas exhaust, and the groove 13 and the groove 31 are perpendicular to the pumping channel 11, respectively, thereby improving the gas pumping effect.
