Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further details.
As depicted in figs. 1 and 2, the utility model comprises housing 1, scaffold 2, two hydraulic pressure installation, two cross connecting rod sliding devices 4, described hydraulic pressure installation is connected with described cross connecting rod sliding device 4, be distributed in the both sides of housing 1 respectively, described scaffold 2 both sides are connected with described housing 1 with described cross connecting rod sliding device 4 by described hydraulic pressure installation, also corrective system is provided with in the middle part of the described front attending device with corrective system, described corrective system comprises correcting bracket 6, correct limiting bracket 5 and fixed support 7, described correction limiting bracket 5 is provided with restraining groove 51, described fixed support 7 is fixed in described housing 1, described correction limiting bracket 5 is vertical in the middle part of described scaffold 2, described correcting bracket 6 one end is flexibly connected with described fixed support 7, the other end is flexibly connected with correction limiting bracket 5, described correcting bracket 6 can slide in described restraining groove 51.
Described hydraulic pressure installation comprises hydraulic rod 31 and door latch 32, for being made described scaffold 2 automatic spring or closed by pressing.
Increase a corrective system, the Point of Strength of scaffold 2 can be made to distinguish on middle and both sides, be similar to a triangle fulcrum force, carrying and the stressed entirety of active part are significantly proposed improvement, and by the adjustment of corrective system, make hydraulic pressure installation open synchronously, effectively avoid rocking and stuck because hydraulic pressure installation ejects inconsistent and pop-up device that is that cause.
Described cross connecting rod sliding device 4 open or closed glide direction contrary with described correcting bracket 6 glide direction in described restraining groove 51.
Described correcting bracket 6 and described correction limiting bracket 7 can be one, be arranged on the centre of housing 1 and scaffold 2, preferred correcting bracket 6 and described correction limiting bracket 7 are set to two respectively, be symmetrical arranged along described scaffold 2 center line, described correcting bracket 6 is connected through the hinge in described fixed support 7 both sides.Correcting bracket 6 can rotate centered by hinge mounting points.Be arranged on the neutral position of housing 1 and scaffold 2, symmetrical design, uniform force.
Described restraining groove 51 is arranged on described correction limiting bracket 5 top, and when scaffold 2 closes, described correcting bracket 6 is bottom described sliding-groove 51, and when described correcting bracket 6 moves to described restraining groove 51 top, described scaffold 2 moves range.
1/5 place of lower fulcrum on described scaffold 2 is located at described restraining groove 51 top, close to the top of scaffold 2, in the scope that restraining groove 51 allows, it is 90 degree that described correcting bracket 6 rotates maximum angle, now, correcting bracket 6 is vertical with described correction limiting bracket 5, and scaffold reaches range.
Described scaffold 2 is provided with Removable hook and mounting hole, also can arrange one of them, is used for installing pop-up device, and described pop-up device can be display screen, mosaic screen, flick door or body of wall etc.Meet the demand that circuit, circuit etc. are safeguarded under pop-up device.
For hydraulic pressure mosaic screen, if there is no middle corrective system, scaffold 2 carries mosaic screen, it is too low that the sliding-groove of housing 1 and scaffold 2 both sides can not be opened, otherwise only can aggravate the top-heavy trend of mosaic screen, therefore, generally be arranged on upper half part of described housing 1 and described scaffold 2, improve the bearing capacity of described scaffold 2, after the utility model increases corrective system, the tie point of housing 1 with scaffold 2 is drawn high, account for 1/5 of lower fulcrum on scaffold and arrange near upper fulcrum, now the sliding-groove of housing 1 and scaffold 2 both sides can set up separately to Lower Half and puts, form triangle stress, performance is more stable, the bearing power of described scaffold 2 is stronger, substantially various pop-up device installation requirements are met.
The utility model is in mosaic screen field, and described scaffold 2 moves range and reached 170 millimeters.Scaffold 2 from enforcement housing distance more away from, safeguard with regard to Vietnamese side just, this is to imagine and to be beyond one's reach in the prior art.
For attending device before 46 cun of hydraulic pressure: it is 150 millimeters that former front attending device opens cross connecting rod sliding device peak apart from Removable hook fulcrum distance from top, be about 1/3 place of lower fulcrum height overall on Removable hook, the actual Point of Strength of scaffold 2 is within the scope of 240 millimeters, Point of Strength is at both sides (hydraulic rod 31 and cross connecting rod sliding device 4), after newly-increased corrective system, the force bearing point of scaffold 2 is brought up to 79 millimeters by 150 millimeters, actual Point of Strength is within the scope of 311 millimeters, Point of Strength is middle respectively, on both sides (hydraulic rod 31 and cross connecting rod sliding device 4), be similar to a triangle fulcrum force, carrying and the stressed entirety of scaffold 2 are significantly proposed improvement.
The utility model can improve the force bearing point of scaffold 2, improve the bearing capacity of scaffold 2, dramatically reduce the wearing and tearing of cross connecting rod sliding device 4, increase the service life, and can compatible similar front attending device all on the market, this corrective system has (panel beating or shape extrusion) with low cost, Be very effective, the feature such as compatible strong.
The embodiment of the above is better embodiment of the present utility model; not limit concrete practical range of the present utility model with this; scope of the present utility model comprises and is not limited to this embodiment, and all equivalence changes done according to the utility model are all in protection domain of the present utility model.
