Technical field
The utility model relates to a kind of retractor device, particularly a kind of movable screen roof pressing type retractor device.
Background technology
That Chinese patent (patent No. 00238030.7) discloses is a kind of " movable screen stretch sealing mechanism ", it can be converted into the upper and lower motion of upper and lower press strip by moving runner with the circular motion of frame dwang 180 degree, thereby reaches the sealing function of movable screen in Qi Ding, bottom.But it needs the manually-operated dwang, just can reach the function that upper and lower press strip stretches out or takes in, and it is convenient inadequately to use, not enough automation.
The utility model content
It is a kind of rational in infrastructure, easy to operate that the purpose of this utility model is to provide, and only needs lean on a back screen toward last screen, just the movable screen roof pressing type retractor device that can open the telescoping mechanism of last screen.
The purpose of this utility model can reach by following measure: a kind of movable screen roof pressing type retractor device, comprise strut, lower supporting rod, last pipe, following pipe, upper spring, lower spring, last square tube, following square tube, it is characterized in that: also have handle, push rod, pull bar, the pull bar sliding sleeve, gear pin and roof pressing type telescoping mechanism, the roof pressing type telescoping mechanism is loaded on by upper cover plate, lower cover, in the cavity that last square tube and following square tube constitute, the tooth bar that stretches out from the one end is connected with push rod, handle links to each other with pull bar, pull bar links to each other with push rod by the pull bar sliding sleeve, and shift finger is located on the push rod.
The purpose of this utility model can also reach by following measure: the roof pressing type telescoping mechanism comprises tooth bar, gear, moving runner, square axis, axle sleeve, spacer, pad, rivet, tooth bar gland, shelves pipe, the wheel and rack engagement, and be installed on the square axis with moving runner is coaxial, moving runner is connected with last strut and lower supporting rod respectively, tooth bar is by tooth bar gland and shelves pipes location, upper cover plate and lower cover by rivet be combined in square tube and under on the square tube.Push rod comprises tube connector and top stem casing two parts, and tube connector and top stem casing interconnect.
The utility model has following advantage compared to existing technology: rational in infrastructure, only need a back screen is leaned on to the screen in front, and just can open the telescoping mechanism of last screen automatically; Pulling handle can be regained press strip up and down again, and is easy and simple to handle.

The specific embodiment
Basis is practical to be described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1～Fig. 7, the utility model comprises strut 1, lower supporting rod 2, goes up pipe 3, down pipe 4, upper spring 5, lower spring 6, go up square tube 7, square tube 8, handle 9, push rod 10, pull bar 11, pull bar sliding sleeve 12, shift finger 13, upper cover plate 14, lower cover 15 and roof pressing type telescoping mechanism etc. down.The roof pressing type telescoping mechanism comprises tooth bar 16, gear 17, moving runner 18, square axis 19, axle sleeve 20, spacer 21, pad 22, rivet 23, gear gland 24, retaining pipe 25 etc.In addition in Fig. 1,28 is main enterprise material, and 29 be ceiling molding, 30 under press strip.Push rod 10 is divided into tube connector 26 and 27 liang of joints of top stem casing; Refute mutually between tube connector 26 and the top stem casing 27 and connect.The roof pressing type telescoping mechanism is loaded in the cavity that is made of upper cover plate 14, lower cover 15, last square tube 7 and following square tube 8.17 engagements of one end of tooth bar 16 and gear, and with moving runner 18 coaxial being installed on the square axis 19; Moving runner 18 is connected with last strut 1 and lower supporting rod 2 respectively; Tooth bar 16 is by tooth bar gland 24 and shelves pipe 25 location.Upper cover plate 14 and lower cover 15 are combined on square tube 7 and the following square tube 8 by rivet 23.The other end of tooth bar 16 links to each other with tube connector 26; Handle 9 links to each other with pull bar 11; Pull bar 11 is connected with tube connector 26 by pull bar sliding sleeve 12; Shift finger 13 is located on the tube connector 26.
During actual act, when movable screen during by last last screen, can compress into top stem casing 27, top stem casing 27 can drive tube connectors 26 and compress into, the tooth bar 16 that is connected on the tube connector 26 will driven gear 17 Rotate 180 degree, thereby the moving runner 18 that drives on same square shaft 19 rotates; Moving runner 18 rotate will with go up strut 1, lower supporting rod 2 stretches out, thereby drive go up pipe 3, ceiling molding 29 and down pipe 4, press strip 30 stretches out down.When ceiling molding 29, when press strip 30 withstands on smallpox and ground down, the compression stress of upper spring 5, lower spring 6 can be pinned moving runner 18 motionless, when when packing up movable screen, only spurring handle 9, pull bar 11, pull bar sliding sleeve 12 will be held gear pin 13 and move outward, push rod 10, tooth bar 16 and then move, driven gear 17, moving runner 18 rotate together, last strut 1, lower supporting rod 2, upward pipe 3, pipe 4, ceiling molding 29 and press strip 30 withdrawals down down.
