Embodiment

Shown in Fig. 2～3, the preferred embodiment that the utility model is used for the blocking unit of display catching device is useful in desktop demonstration module, and this demonstration module comprises: one is display 2, a catching device 3, a torsion elements 4, this blocking unit 5 of LCD screen, an and shell that coats catching device 3 (for ease of explanation, below the graphic display module of painting all removed shell).

Cooperate shown in Figure 4ly, this catching device 3 has a pedestal 31, and is located at main frame 32, a sliding part 33 on this pedestal 31 and a linkage unit 34 (being shown in Fig. 2).This pedestal 31 comprises a leveling board 311 and from the dull and stereotyped 311 upwardly extending upright plates 312 of these leveling board 311 1 side vertical water, and this upright plate 312 forms the length of a level to perforation 313.

Wherein, this main frame 32 comprises two upstanding sidewalls 321 respect to one another and 322, and the connecting wall 323 of this two sidewall 321,322 of connection.This two sidewall 321,322 and connecting wall 323 define a slide rail 324 jointly.This main frame 32 comprises that more one accepts wall 325 from this connecting wall 323 towards one of slide rail 324 horizontal projections in addition.

This sliding part 33 is to slide up and down to be located in the slide rail 324, and comprise one first body 331 and one second body 332, its other horizontal cross sectional geometry is all smooth U-shaped, thereby first and second body 331 is when 332 dock in opposite directions with the U-shaped opening, and both define a space 333 jointly.When sliding part 33 in slide rail 324 during slippage, what this space 333 provided main frame 32 accepts wall 325 bufferings, and is unlikely the shift motion mutual interference mutually with sliding part 33.

Look back Fig. 2, this linkage unit 34 is first body, 331 tops that are attached to sliding part 33 with the nut packing, have an adaptor 341 and a lockplate 342, this lockplate 342 is to decide to use for display 2, and see through this adaptor 341, this display 2 and lockplate 342 be able to relative integratedly catching device 3 carry out level to the visual angle change in location.

One end 41 of this torsion elements 4 is accepted wall 325 around what song became the scrollwork sample and was fixed in main frame 32,42 of the other ends of this torsion elements 4 are different from the scrollwork sample of this end 41, and present the straight interlocking that extends sample second body, 332 bottoms to sliding part 33, the torsion elements 4 of present embodiment is a fixed force spring, and sliding part 33 perseverances are bestowed upwards acting force corresponding to display 2 gravity.

This blocking unit 5 has a locking part 51, and colludes and hold bar 52, and an elastic component 53.These locking part 51 tops are second body, 332 bottoms that are locked in sliding part 33, and its position is roughly corresponding with the end 42 of torsion elements 4.This locking part 51 comprises that one is parallel to the down outstanding extension 511 of sliding part 33 direction of motion, and one from the extension the 511 reverse service portions 512 of bending up bottom.The extension 511 of this locking part 51 forms arcuations with service portion 512 intersection root edges 510, and this service portion 512 defines a groove 513 to fovea superior is curved, and this groove 513 is a lateral openings.

This colludes an end 521 of holding bar 52 is the connecting wall 323 bottom center places that are articulated in main frame 32, and 522 of its other ends traversed the perforation 313 of slide rail 324 hypomeres and this base upright plate 312 that stretches through out.

Shown in Fig. 5～6, one first end 531 of this elastic component 53 is to connect admittedly at main frame 32, as for one second end 532 in contrast to first end 531 is to be linked to contiguous colluding to hold the structure division that bar 52 penetrates slide rail 324, and see through the extension recovery power of elastic component 53 itself, this is colluded to hold bar 52 horizontal in a predetermined direction (promptly being equivalent to the left side among Fig. 5) pulling, the elastic component 53 that is adopted in the present embodiment is an extension spring.

Be illustrated in figure 6 as 32 of these sliding part 33 relative main frames in a peak position, for another Figure 7 shows that this sliding part 33 with respect to Fig. 6 position at a lowest point.In this peak position, the overwhelming majority of torsion elements 4 tendency continues around folding toward crimp end 41, and it is maximum that the height of whole catching device 3 reaches, and promptly representing this display 2 (not drawing among the figure) is that the position is in an extreme higher position.

Simultaneously as shown in Figure 7, if the user thinks that the position of display 2 (not drawing among the figure) is too high, and when desiring to be adjusted to lower position, only need force in sliding part 33 tops, sliding part 33 is pressed to book office, most of torsion elements 4 structures that originally present curl sample and close end 42 are transformed into the extension sample then along with sliding part 33 leads.Because of these torsion elements 4 perseverances are bestowed the upwards acting force of sliding part 33 corresponding to display 2 gravity, after person's application of force to be used disappears, this sliding part 33 can't continue that relative main frame 32 continues downwards or reverse slide up in slide rail 324, to rest on the halt of the last application of force of user, put the right position that just user thought.Certainly, the user is according to self-demand, and any point that chooses at random in the slide rail 324 stops the application of force, also presents the stepless aspect with regard to the relative position of representing 32 of sliding part 33 and main frames.

Cooperate shown in Figure 8, if the user want with display 2 (not drawing among the figure) view and admire highly drop to minimum, just can oppress sliding part 33 and drop to minimum point, when this sliding part 33 stressed interlock locking parts 51 together during slippage downwards, this colludes holds bar 52 and slips into this groove 513 along arcuation root edge 510, collude and hold bar 52 and colluded securely by locking part 51 and adhere to so that this sliding part 33 can't be arbitrarily relatively main frame 32 slide.

If the user desires to readjust display 2 height, as long as apply the external force in contrast to elastic component 53 action directions (promptly being equivalent to right direction among the figure) to colluding the exposed end 522 of holding bar 52, make this collude and hold the groove 513 that bar 52 is deviate from locking part 51, make this sliding part 33 no longer be restricted effect, then relative main frame 32 is free to slide and get back to as Fig. 5 or position shown in Figure 6.

As previously mentioned, the utility model can see through sliding part 33 according to various user demands and slide against up and down in the slide rail 324, adjust the height of catching device 3 flexibly, and then in response to the user for the requirement for height of viewing and admiring display 2, particularly after the external force that puts on sliding part 33 tops disappears, the upwards abundant antagonism display 2 of acting force that torsion elements 4 provides puts on the gravity on the catching device 3, and more making whole height represent does not have the section adjustment modes, but not is confined to specific several high selectivity.

With the elastification height control pattern that the utility model possesses, secondary monitor 2 catching device 3 levels relatively turns to, and the visual angle collocation of dual dimension provides excellent adaptability for the utility model.

Moreover the design of blocking unit 5 is stable at the lowest point except guaranteeing sliding part 33, has more the limit and utilize effect for manufacturer; furtherly; in the process of transporting, in order to reduce packing and transportation cost, all products must be compressed to minimum volume as much as possible.

And the utility model just can meet the demand that minimum is transported volume, even if moreover transporting the road conditions that meet with the injustice of jolting on the distance, locking part 51 can securely collude to block to collude holds bar 52, principal element as the 33 random displacements of limit slippage part, catching device 3 is not badly beated because of the situation of transporting slide onto maximum length (being that sliding part 33 travels to the peak position), kept the high stability quality of transporting.

Conclude above-mentioned, the utility model utilizes sliding part 33 relative main frame slippages about in the of 32, provide display 2 in the change of viewing and admiring on the height, to cater to outside user's demand, more when sliding part 33 moves to lowest point, collocation locking part 51 clips firmly collude holds bar 52, the 33 any displacements of limit slippage part, thereby can reach the utility model institute demand purpose.
