Description

Display

Technical field

The present invention relates to a kind of electronic equipment, especially relate to the standoff display of a kind of tool.

Background technology

See Fig. 1 and Fig. 2, a kind of display, comprises screen 100 and support 200.Screen 100 back is provided with outwardly directed two the first braces 101, and the top of support 200 also has two the second braces 201, and bolt 300 is connected with spiral shell 400 with the second brace 201 afterwards through the first brace 101.

In order to ensure that screen and support can relatively rotate, and can fix at an arbitrary position again, wanting that the friction force between the first brace and the second brace regulates is appropriate, and this friction force is provided by the pretightning force between screw bolt and nut.Due to the existence of this friction force, when needing to regulate display angle, we want hand steered a screen, and a hand support, so just can complete the adjustment to display angle.Display is after repeatedly regulating in addition, and it is responsible for fastening nuts and bolt and may gets loose.

Summary of the invention

The present invention is directed to deficiency of the prior art, provide a kind of display, angular adjustment can be completed by a hand, and can not get loose.

For solving the problems of the technologies described above, the present invention is solved by following technical proposals: display, comprise the screen and support that are mutually rotationally connected, also comprise a latch and aerating device, described screen is connected with described holder pivots with the shaft hole that described support is arranged through described screen by described latch, described aerating device comprises button, first cavity and snorkel, described button one end is slidably connected in described first cavity, first spring is provided with in described first cavity, the two ends of described first spring are against described button and described first cavity bottom respectively, the bottom of described first cavity has the first retaining valve of a through hole and an only import but no export, one end of described snorkel is connected with described through hole, described latch is divided into two-section, wherein the end of a section is provided with second cavity, the bottom of described second cavity is provided with the second retaining valve and a spout hole of an only import but no export, the other end of described snorkel is connected with described second retaining valve, a piston is slidably connected in described second cavity, described piston is connected with a piston rod, the part that described piston rod is positioned at described second cavity arranges second spring, described piston rod is positioned in the part outside described second cavity and is fixed with an aerated rubber loop, the end of described piston rod is connected with another section of described latch.During normal state, rubber ring is under the effect of the second spring, compressed, the outer ring of rubber ring and the inwall of shaft hole push against, and screen can not rotate by opposite brackets, when needing adjusting screen angle, first press the button, the air in the first cavity is discharged in the second cavity by snorkel by button, and at this moment the second spring is compressed, rubber ring is no longer squeezed, and at this moment screen can rotate by a hand easily.When screen rotates, the second spring also, in the middle of elasticity is gradually recovered, when spring returns to original state, is fixed again between screen and support.When elasticity is recovered, the air in the second cavity is discharged from spout hole, and the size of spout hole directly determines screen can the freely regulated time.As long as this structure second spring did not lose efficacy in addition, the thing got loose would not be occurred, and spring normally uses decades all can not what's wrong.

In technique scheme, preferably, the bottom at the described screen back side is provided with a groove, is provided with two holders in described groove, and the top of described support is between two described holders.

The invention has the beneficial effects as follows: during normal state, rubber ring is under the effect of the second spring, compressed, the outer ring of rubber ring and the inwall of shaft hole push against, and screen can not rotate by opposite brackets, when needing adjusting screen angle, first press the button, the air in the first cavity is discharged in the second cavity by snorkel by button, and at this moment the second spring is compressed, rubber ring is no longer squeezed, and at this moment screen can rotate by a hand easily.When screen rotates, the second spring also, in the middle of elasticity is gradually recovered, when spring returns to original state, is fixed again between screen and support.When elasticity is recovered, the air in the second cavity is discharged from spout hole, and the size of spout hole directly determines screen can the freely regulated time.As long as this structure second spring did not lose efficacy in addition, the thing got loose would not be occurred, and spring normally uses decades all can not what's wrong.

Embodiment

Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail: see Fig. 3 to Fig. 5, display, comprise the screen 1, support 2, latch 3 and the aerating device 4 that are mutually rotationally connected, the bottom at screen 1 back side is provided with a groove 11, be provided with two holders 12,13 in groove 11, the top of support 2 is between two holders 12,13.Screen 1 and support 2 are rotatedly connected through shaft hole 1a, 2a that screen 1 and support 2 are arranged by latch 3.

See Fig. 4, aerating device 4 is arranged on the centre position at screen 1 top.Aerating device 4 comprises button 41, first cavity 42 and snorkel 43, button 41 one end is slidably connected in the first cavity 42, first spring 421 is provided with in first cavity 42, the two ends of the first spring 421 are against bottom button 41 and the first cavity 42 respectively, the bottom of the first cavity 42 has the first retaining valve 423 of a through hole 422 and an only import but no export, and one end of snorkel 43 is connected with through hole 422.

See Fig. 5, latch 3 is divided into two-section, wherein the end of a section 31 is provided with second cavity 311, the bottom of the second cavity 311 is provided with the second retaining valve 312 and a spout hole 313 of an only import but no export, the other end of snorkel 43 is connected with the second retaining valve 312, a piston 5 is slidably connected in second cavity 311, piston 5 is connected with a piston rod 51, the part that piston rod 51 is positioned at the second cavity 311 arranges second spring 314, piston rod 51 is positioned in the part outside the second cavity 311 and is fixed with an aerated rubber loop 6, the end of piston rod 51 is connected with another section 32 of latch 3.

See Fig. 6, the aerated rubber loop 6 adopted in concrete the present embodiment adopts the material with certain viscosity to make, outer ring has 4 uniform folds 61, and these folds 61 can outwards be heaved when aerated rubber loop 6 pressurized, and these are heaved and fit with shaft hole 2a inwall.

See Fig. 7, when screen and support have the trend of rotation, the side under tension heaved, under the effect of this pulling force, aerated rubber loop 6 is evened up heaving the side by pulling force, then there is fold in relative opposite side, the fold that these deformation produces is adjacent to through-hole wall more, makes the rotary damping more XXL between screen and support.And the screen rotating torque relative with support is larger, this damping is also larger.The aerated rubber loop 6 of this form, only needs very small spring just can firmly the relatively rotating of lock-screen and support.
