Embodiment
With reference to Fig. 1～Fig. 4; The present invention is a kind of novel ground draw curtain, comprises base 1 and is curled in the curtain 2 in the base 1, and the top of base 1 is provided with upper end cover 11; Be provided with in the upper end cover 11 and the fixing trombone slide 3 in the upper end of curtain 2; The lower end of base 1 inherent curtain 2 is provided with the tube 4 of recoverable curtain 2, and 11 of base 1 and upper end covers are provided with the linkage that can have level to stretch, and also are provided with the curtain crimping device that is used to regain curtain 2 in the base 1.
This novel ground draw curtain has been installed the linkage that can have level to stretch at upper end cover 11 that is arranged at curtain two ends about in the of 2 respectively and 1 of base; Thereby can after opening the ground draw curtain, curtain 2 tops be positioned apart from base 1 arbitrary height place; The curtain crimping device that is provided with in the base 1 can be conveniently regained curtain 2 in base 1 after being used to complete and is effectively protected, and this type of ground draw curtain can more convenient user use in different use occasions more flexibly.
As the preferred embodiment of the present invention; Linkage comprises the hinged respectively articulated linkage 31 that is installed on upper end cover 11 and the base 1; The other end of two articulated linkage 31 is installed with cam lever 32; Be provided with pitman shaft 33 in the heart with the junction of articulated linkage 31 and the cam circle on another cam lever 32 on one cam lever 32, pitman shaft 33 two ends respectively with the center of circle of a cam lever 32 wherein and another cam lever 32 near the junction hinge-coupled of a side of articulated linkage 31.
As the preferred embodiment of the present invention, be provided with extension spring 34 in the shaft of two pitman shafts 33, an end of extension spring 34 is fixedly installed in the termination of pitman shaft 33, and the other end of extension spring 34 is connected with stay cord 35, and the other end of stay cord 35 is fixedly installed in the articulated linkage 31.
The pitman shaft 33 of forming two cam levers 32 of this linkage and connecting two cam levers 32 is formed the bar linkage structure of a parallelogram, when ensureing that curtain 2 can effectively shrink, has also guaranteed the support strength of linkage to curtain 2.
And local draw curtain is finished using; Under the effect of curtain crimping device, regain in curtain 2 to the base 1; After simultaneously linkage being shunk, the projection on the cam lever 32 just in time withstands the stay cord 35 that connects with extension spring 34, makes extension spring 34 be elongated; Obtain bigger restoring force in the extension spring 34, thus the more convenient ground draw curtain that struts.
As the preferred embodiment of the present invention, the curtain crimping device comprises the torsion spring 41 that is installed in the tube 4, and an end of torsion spring 41 is fixed in and is arranged on the runner 42 of tube 4 inside with tube 4 rotations, and the other end of torsion spring 41 is fixedly installed in the base 1.
As the preferred embodiment of the present invention, the both sides of base 1 are provided with base side cover 12, and base side cover 12 is provided with the bearing pin 43 that is parallel to torsion spring 41, and bearing pin 43 is provided with pin hole 44, and torsion spring 41 is provided with the rivet 45 that passes pin hole 44.
As the preferred embodiment of the present invention, torsion spring 41 inherent runners 42 and 43 of bearing pins are provided with stay pipe 46, and parcel stay pipe 46 also is provided with protection tube 47 in the inboard of torsion spring 41.
In the curtain 2 quilt processes that strut; Torsion spring 41 1 ends of curtain crimping device are reversed; Thereby when linkage shrank, the tube 4 fixing with the bottom of curtain 2 can rotate one section side that is fixed on base 1 through bearing pin 43 of stay pipe 46 around stay pipe 46 under the restoring force effect after torsion spring 41 quilts reverse; Thereby form the central shaft of torsion spring 41, to prevent that torsion spring 41 is in its length direction generation deformation.
Inner chamber internal fixation at tube 4 is equipped with runner 42, the surface on the runner 42 be provided with some can be with the fixing runner groove on it of an end of spring, thereby in the process of tube 4 rotations, can drive torsion spring 41 rotations.
In the arranged outside of stay pipe 46 protection tube 47; At torsion spring 41 in the process of stay pipe 46 rotation; Protection tube 47 can effectively protect stay pipe 46 not receive torsion spring 41 wearing and tearing on the one hand; Protection tube 47 can effectively prevent in torsion spring 41 twist process and stay pipe 46 friction generates noises on the other hand, plays effective sound deadening.
As the preferred embodiment of the present invention; 11 of base 1 and upper end covers are provided with the end cap locking device; The end cap locking device comprises and is arranged at the button 5 in the upper end cover 11 and is fixedly installed in the button snap close 51 in the base 1; The lower end of button 5 is provided with the hook 52 that can embed in the button snap close 51, also is provided with button chute 53 in the upper end cover 11, and a side of button chute 53 inherent hooks 52 also is provided with back-moving spring 54.
When draw curtain does not use on ground, can upper end cover 11 be locked on base 1 through the end cap locking device that is arranged at 11 of base 1 and upper end covers, with the apparatus structure of effective protection curtain 2 and base 1 inside.When needs use, can promote button 5 and in button chute 53, slide, make hook 52 break away from button snap close 51, thereby can open the end cap locking device, carry out the use of ground draw curtain.After button 5 was slided, under the effect of back-moving spring 54, button 5 can set back.
As the preferred embodiment of the present invention, the bottom of base 1 is provided with base support pin 6, and the both sides of base support pin 6 are equipped with regulates pin 61, and adjusting pin 61 is provided with the adjusting bolt 62 with base support pin 6 thread connection.
Because the ground draw curtain prevents to use with ground, broken terrain will impact its stability in use.Through base support pin 6 on the base 1 that is arranged at the ground draw curtain and adjusting pin 61, regulate the height of the adjusting pin 61 on the base support pin 6, can make the ground draw curtain on some broken terrain, place.
Certainly; The invention is not limited to above-mentioned embodiment; Those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of spirit of the present invention, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
