Embodiment

Herein below is to combine specific accompanying drawing further description made for the present invention, it is impossible to assert the present invention's Specific implementation is confined to these explanations.

As shown in figure 1, a kind of ground draw curtain of Simple telescopic of the utility model is by being assemblied in the lid of shell 1 of ground draw curtain The support bar switch module 102 of lifting latch components 101 and its clamping matching simultaneously makees the rotation of curtain support bar and fixation kit 103 and the fixing leg component 104 of the lower section of shell 1 form.The lifting latch components (101) are provided with lifting seat (14)； Support bar switch module (102) includes support bar (22).Situation is folded when Fig. 2 is then the utility model off working state.

As shown in figure 3, illustrating lifting latch components 101 of the present utility model, it includes lifting lock 12 and is provided with lock Button spring 13, and lift lock 12 and be first connected with the screens set in lifting seat 14, then insert anchor switch above lifting seat 14 Button 15 is simultaneously aligned with the axis hole on lifting lock 12, then the interior hexagonal headless screw on the axis hole side of lifting lock 12 11, handle 16 is finally installed；And the support bar 33 on top be provided with cylinder iron pin 36 connect clip torque spring 37 and That props up an intermediate plate 35 props up seat 34.

With reference to shown in Fig. 3 and Fig. 4, during its off working state, the chamfering climbers and supporting rod seat 17 on lifting lock 12 are tight Link closely, and when being operated, anchor switch button 15 need to only be slided to arrow assigned direction and lift carrying on lifting seat 14 Hand 16.

With reference to shown in Fig. 3, Fig. 4 combination Fig. 5, when the support bar 33 of top is propped up to required height, its top is installed Have the active force of intermediate plate 35 of the cooperation clip of cylinder iron pin 36 torque spring 37 props up seat 34, when lifting seat 14 is placed on intermediate plate 35 and when propping up the jaws position between seat 34, due to the effect of clip torque spring 37, so that both tightly pin, receive Needed during conjunction by lower clamping piece 35, its role is to prevent the curtain downslide that comes off suddenly from causing damage.

As shown in fig. 6, illustrate support bar switch module 102 of the present utility model, it includes three kinds of different sizes and interior The support bar 22,27,30,33 that external diameter cooperates, and support bar switch base 23,28,31, and support bar shift knob 25, 29th, 32, because principle is the same, does not tire out one by one and state, select one detailed description：Support bar 22 coordinates with the internal-and external diameter of support bar 27, and props up Strut 22 is provided with hole position and coordinates support bar switch base 23, and the support bar switch base 23 is with being provided with support bar switch spring 24 Support bar shift knob 25, and support bar 27 is provided with self-tapping screw 26, with reference to shown in Fig. 7, support bar 22 as external diameter most Big bar and there is fixed support bar switch base 23, and the support bar shift knob 25 of support bar switch spring 24 be installed, Because it provided with fillet surface causes support bar 27 to be easier to lift in the presence of its chamfering in stretching, and due to flat when pushing Angle, which acts on, make it that zero accident slides support bar 27 at work, and is additionally provided with self-tapping screw in support bar 27 to prevent from making it Overexerted during stretching and cause two rod members to depart from, pulled away.

With reference to shown in Fig. 8-11, the support bar rotation on shell and fixation kit 103 are illustrated, and under shell The fixing leg component 104 of side forms the main support fulcrum of whole curtain, wherein support bar rotation and fixation kit 103 it Including the support bar 22 for being cased with rotating rod set 21 on shell 1, pass through the shape of cylinder iron pin 18 and supporting rod seat 17 Shape designs so that support bar 22 can realize that 90 degree of rotations arbitrarily fold so as to be formed, and the support of connecting cylinder iron pin 18 Support bar leg 19 is set in bar leg fixed cover 20 can make adjustments fixation, and two legs 41 below local draw curtain shell arrange shape During into curtain entirety Gravity support, at this moment it is touched with ground by adjusting support bar leg 19 and form more fulcrum supports Power so that curtain is more steady.

With reference to shown in Figure 11, the planted agent of leg 41 first installs leg buckle 45 in corresponding circular hole, then in the side of shell 1 It is inserted in by opening edge along the screens of leading in shell 1, until being opened in shell at circular hole, locating core buckle 44 then is pressed into branch Pin 41 is fixed at the circular hole equipped with leg buckle 45, because locating core buckle 44 is designed as chamfering open ports, is made in human hand Locking is formed due to extruding force by locating core buckle 44 with chamfering under firmly and by opening-wide state, so as to be squeezed into leg In 41, the elasticity when reaching relative screens due to glue part restores it into most original state again；Secondly card is provided with leg 41 The regulation leg 42 that groove contacts with ground forms fastening relationships, and final leg adjustment knob 43 is intuitively adjusted by human hand, So that operation is more convenient.

More than each part illustrate or any combination therein, all among the present general inventive concept, herein not Do to tire out again and state, for general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, Some simple deduction or replace can also be made, should all be considered as belonging to protection scope of the present invention.
