DETAILED DESCRIPTION

[0026] The technical solutions of the present application will be described in further detail below in combination with preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0027] Please refer to Figures 1-9 The present application provides a technical solution: a pressure test device for display glass structure, comprising a platform 1, five expansion joints 2 are arranged above the platform 1, and support plates 3 are fixed to the upper ends of the five expansion joints 2.

[0028] A guide rail is fixed on one side of the platform 1, and a connecting plate 4 is slidably connected on the guide rail. A pin is fixed on one side of the connecting plate 4, and a pressure test chamber 5 is slidably connected to the outside of the pin. A hydraulic plate 51 is slidably connected to the inner wall of the pressure test chamber 5. A pressure rod 52 is fixed below the hydraulic plate 51. The glass is laid flat on the support plate 3, and the glass structure is observed by laying it flat. The upper part of the pressure test chamber 5 is connected to an external hydraulic pump pipeline. After the pressure rod 52 moves downward, it contacts the glass surface.

[0029] After the glass is laid flat on the support plate 3, the operator moves the connecting plate 4, causing the pressure testing chamber 5 to move longitudinally on the guide rail. At the same time, the pressure testing chamber 5 is moved laterally on the pin shaft, thereby adjusting the position of the pressure rod 52 so that it is aligned with the pressure testing point of the glass. After adjustment, the external hydraulic pump runs, injecting liquid into the pressure testing chamber 5. The pressure pushes the hydraulic plate 51 to slide downward along the inner wall of the pressure testing chamber 5, and the pressure rod 52 moves downward and contacts the upper surface of the glass, applying pressure to the upper surface of the glass, thereby conducting a pressure test on the glass. The pressure value borne by the glass is calculated according to the pressure of the hydraulic pump. The test is convenient and can be performed on both thick and thin glass, making it widely applicable.

[0030] Four arc-shaped disks 6 are set on the top of the platform 1, and four telescopic joints 2 are slidably connected to the four arc-shaped disks 6 respectively, and the middle telescopic joint 2 is slidably connected to the upper surface of the platform 1.

[0031] Two guide pillars are fixed above the platform 1, and threaded discs 7 are slidably connected to the two guide pillars. A screw 71 is threadedly connected to the middle of the threaded disc 7, and a slide rail 72 is connected to one end of the screw 71 by a bearing. The support plates 3 are all slidably connected to the slide rail 72.

[0032] Example 1:

[0033] like Figure 7 As shown, the glass being tested is relatively thin. The operator can rotate the screw 71 to move it to the right while rotating it through the threaded hole of the threaded disc 7. During the movement, the screw 71 drives the slide rail 72 to move to the right. At this time, the support plate 3 is pulled to the right, causing the telescopic joint 2 to slide and move on the arc-shaped disc 6. Simultaneously, the support plate 3 slides on the slide rail 72, reducing the distance between the support plates 3. For thinner glass, the density of the support points at the bottom of the test point can be adjusted to prevent the glass from cracking due to insufficient support strength at the bottom caused by excessive force on the glass test point, thus protecting the glass. The distance between the support plates 3 can be freely adjusted according to the test pressure set at the test point. The operation is convenient and efficient, and pressure testing can be performed quickly, efficiently, and stably for both thin and thick glass.

[0034] Four arc-shaped disc 6 and platform 1 between the rotating connection, and fixed by nut;

[0035] Embodiment two:

[0036] As Figure 9 The glass is extremely thin, and the glass protection needs to be strengthened during the pressure test. At this time, the expansion joint 2 is limited by the arc-shaped disc 6 after moving to the limit position, so it cannot move. At this time, the operator can loosen the nut, so that the arc-shaped disc 6 rotates and drives the expansion joint 2 to continue to move, thereby further narrowing the distance. Without changing the type of arc-shaped disc 6, the cost is reduced, and the entire test device can support the test of very thin glass, and the application range is wider.

[0037] The upper side of the platform 1 is fixed with a T-shaped block, and the T-shaped block is located on one side of the threaded disc 7. The outer side of the screw rod 71 is threadedly connected with a circular block 711, and the circular block 711 is located above the T-shaped block and in contact with each other. One end of the circular block 711 is arc-shaped;

[0038] Embodiment three:

[0039] When the tested glass is relatively thin and the pressure rod 52 cannot contact the glass due to the moving distance, the operator can rotate the circular block 711 to move upward while rotating on the screw rod 71. The left end of the circular block 711 is in contact with the upper surface of the T-shaped block. With the movement of the circular block 711, the T-shaped block is gradually lifted upward, thereby driving the screw rod 71 to move upward. The screw rod 71 drives the threaded disc 7 to move upward through the guide column, and at the same time drives the support plate 3 to move upward through the sliding rail 72, and pulls the expansion joint 2 to elongate. The relatively thin glass can be lifted upward to avoid the failure of the pressure test. Whether it is for the support point or the position height of the glass bottom, it can be quickly adjusted, and the application range of the test glass is further increased.

[0040] The T-shaped block includes block one 81 and block two 82. The block one 81 is fixed to the upper surface of the platform 1. One side of the block two 82 is in contact with one side of the threaded disc 7, and there is a gap between the block two 82;

[0041] A through hole is arranged at the bottom of the block one 81, and a supporting rod 821 is slidably connected in the through hole. A top block 9 is arranged above the supporting rod 821. A spring one 10 is arranged between the upper side of the top block 9 and the bottom of the block two 82. A spherical body 822 is fixed to the outer side of the supporting rod 821, and the spherical body 822 is located below the top block 9 and in contact with each other. A limiting block is fixed to the bottom of the threaded disc 7, and one side of the limiting block is in contact with one end of the top block 9. A clamping block one is fixed to the left side of the block one 81. A clamping block two is fixed to the bottom of the block two 82, and the clamping block two is located below the clamping block one and in contact with each other.

[0042] Embodiment four:

[0043] If the pressure of the pressure rod 52 on the glass reaches the set value and the pressure needs to be continuously increased, the external hydraulic pump gradually increases the hydraulic pressure in the pressure test cavity 5 until the set test pressure value is reached. In order to protect the glass, the pressure of the pressure rod 52 on the glass is greater than the pressure of the spring one 10, and the pressure applied by the circular block 711 on the block two 82 is less than the pressure of the external hydraulic pump. The spring one 10 is deformed, the block two 82 slides downward between the threaded disc 7 and the block one 81, so that the support plate 3 shortens the telescopic section 2 downward, and the glass can smoothly and slightly descend, so as to avoid the glass being crushed by the continuously increasing pressure, thereby playing a role in protecting the glass, and the reaction is fast and the protection is more timely.

[0044] The spring one 10 is provided in plurality, and is divided into different models according to the elastic force;

[0045] Example five:

[0046] The thickness of the glass is different, and the pressure during the test is different. At this time, in order to protect the pressure test protection, the block two 82 can be taken out, the spring one 10 is replaced, and the model of the spring one 10 is selected according to the test pressure value, so as to adapt to different test pressures, so as to protect the glass and ensure the smooth progress of the test.

[0047] The left end of the support rod 821 is fixed with a push rod 823, and the front and rear ends of the push rod 823 are spherical. After the arc-shaped disc 6 rotates, the spherical part of the push rod 823 is in contact with the arc-shaped disc 6, and the push rod 823 moves to the right.

[0048] The right side of the spherical body 822 and the left side of the block one 81 are provided with the spring two 11;

[0049] Example six:

[0050] As shown in Figure 8 the embodiment two, when testing the extremely thin glass, the pressure rod 52 has been pressed on the glass during the test. At this time, the distance between the support plates 3 is adjusted by rotating, and the arc-shaped disc 6 rotates and contacts the spherical part of the push rod 823. The push rod 823 drives the spherical body 822 to move to the right side through the support rod 821 until the spherical body 822 is separated from the contact with the top block 9. The top block 9 is forced to quickly descend, so that the block two 82 quickly descends, so that the glass can instantaneously descend, and the pressure of the pressure rod 52 on the glass instantaneously decreases, thereby protecting the extremely thin glass to the greatest extent. When the support plate 3 moves, the upper end thereof and the bottom surface of the glass rub against each other, so as to avoid the glass being damaged by friction under a large pressure, thereby further protecting the extremely thin glass and fully avoiding the glass being broken or damaged.

[0052] Finally, it should be pointed out that: the above examples are only used to illustrate the technical solutions of the present application, and are not limited thereto. Although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
