Description
Technical field
The present invention relates to automatic invisible screen window, particularly a kind of safety speed reducer of automatic invisible screen window.
Background technology
Automatic invisible screen window adopts spring backrush device at present, be after pulling out gauze with straining beam, place torque spring in the yarn box can produce to a certain degree backrush power, and automatic invisible screen window promptly to be the backrush power that produces by the spring in the gauze box go into the gauze backrush when not using gauze collects in the yarn box, because it is stronger that spring produces backrush power, when packing up gauze the straining beam of gauze one end always with the shell yarn oral area Fast Collision of yarn box, make gauze be subjected to impact force, except that long-term use can cause gauze and straining beam and yarn box damage, because the straining beam yarn box is a metal product, Fast Collision is easily sent the big sound and is crushed user's hand, is badly in need of improving the practicality and the safety of automatic recessive screen window.
The shape of existing automatic invisible screen window is as shown in the accompanying drawing 1, window yarn box (1) is square or semicircular, inside is provided with and the gauze scroll bar pipe (7) of gauze (2) stressed joint (accompanying drawing 1 do not show can referring to accompanying drawing 2), gauze (2) and straining beam (3) stressed joint, the upper and lower of straining beam (3) and gauze (2) is embedded in respectively in upper hopper chute (4) and the gliding groove (5).Pulling straining beam (3) gauze (2) is promptly pulled out, and straining beam (3) fastening is on holddown groove (6); When regaining gauze (2), pulling straining beam (3) gets final product, at this moment because the backrush power of torque spring (11) is stronger, and the quick backrush of meeting when straining beam (3) is pulled away from holddown groove (6), collision screen window net box (1).
Summary of the invention
Purpose of the present invention just provides a kind of novel automatically latent screen window safety speed reducer, make automatic invisible screen window can be at the uniform velocity, mild backrush, to solve the ubiquitous problem of present automatic invisible screen window.
The present invention sets up deceleration device on the automatic invisible screen window that above-mentioned accompanying drawing 1 is showed.
The technical scheme that realizes the object of the invention is: the scroll bar pipe Plastic cap that is located at gauze scroll bar pipe upper end is a rectangular flat, establish the holder of one section tubular on the lower panel, tight fit is installed 1 micro metal unilateral bearing in this holder, this micro metal one-way shaft internal diameter circular hole tight fit is installed 1 round metal bars, this round metal bars hypomere middle part is installed with 1 gear-like rotating disk, described round metal bars hypomere is fit in the internal diameter circular hole of pole sleeve, the upper end of this pole sleeve sets firmly the sleeve flange dish, and described pole sleeve tight fit is installed in the gauze scroll bar pipe.
Safety speed reducer for automatic rolling screen window of the present invention can be avoided having the problem that automatic invisible screen window straining beam Fast Collision produces the sound and crushes user's hand now, and is simple and reasonable for structure, the practicality and the safety that can improve automatic invisible screen window.
Do more detailed explanation below in conjunction with accompanying drawing with regard to the present invention.
Description of drawings
Fig. 1: be existing automatic invisible screen window elevational schematic view.
Fig. 2: the structural representation that is an embodiment of apparatus of the present invention.
The specific embodiment
What Fig. 2 showed is to implement textural association of the present utility model on existing a kind of automatic invisible screen window.
It is fixedly sleeved on scroll bar pipe lower end cap (10) top that this spring of torque spring (11) (11) lower end is installed in the gauze scroll bar pipe (7), there is groove fixed copper core (9) upper end, grafting is gone in the lower end cap (10), the both sides, lower end have protruding shelves to be plugged in the yarn box plastics lower end caps (8), these yarn box plastics lower end caps (8) are rectangular flat (going to a corner), and are plate shaped identical with yarn box Plastic cap (12).
The technical scheme content of the present invention design is on Fig. 2 top, promptly be arranged on yarn box Plastic cap (12) to the gauze scroll bar pipe (7) between.
The outside dimension of the internal diameter of set one section tubular holder (13) and metal unilateral bearing (19) has elementary errors on the lower panel of yarn box Plastic cap (12), be to fix when realizing that metal unilateral bearing (19) is embedded in the tubular holder (13), realize friction tight purpose of design.Fixed bar (14) can be realized 1 end with screw (18) retainer spring washer (17) spring fixed seat (15) fixing spring (16), this spring (16) is a tension spring, in the small sircle hole of other end cross-under retainer spring washer (17), the front end of spring washer (17) catches on the gear front end on the gear-like rotating disk (20), impact force when its effect can slow down when damage of bearings or fault the gauze backrush.
The external diameter of the internal diameter size of micro metal unilateral bearing (19) and round metal bars (21) also is that small tolerance is arranged, because both are friction tight, the gear that round metal bars (21) goes up on the gear-like rotating disk (20) fixedly establish is the inclined plane, and the gear bevel angle is that 15～75 ° of its angles are convenient to spring washer (17) and are caught on the gear of rotation.The latter half of round metal bars (21) is plugged in the pole sleeve (22), the outside dimension of round metal bars (21) is less than pole sleeve (22) internal diameter, be gapped, be convenient to add damping oil (24), the following contact of the top and gear-like rotating disk (20) of the sleeve flange dish (23) that the upper end of pole sleeve (22) sets firmly, this contact surface is also annotated damping oil (24) to increase frictional resistance, and sleeve flange dish (23) tight fit is installed in the gauze scroll bar pipe (7).
The realization of deceleration of the present invention, the one, produce frictional resistance because annotate damping oil (24) on the wall gap of round metal bars (21) and pole sleeve (22) and gear-like rotating disk (20) and sleeve flange dish (23) the two dish contact surfaces, slow down backrush power; The 2nd, because metal unilateral bearing (19) is one-directional rotation, its rotation direction is straining beam (3) gauze scroll bar pipe (7) rotation direction when pulling out, so metal unilateral bearing (19) rotates simultaneously and gauze can be pulled out easily; When the backrush of gauze (2) income yarn box scroll bar pipe (7), because of being subjected to metal unilateral bearing (19) restriction of one-directional rotation only, bearing can't run up to move and use, scroll bar pipe (7) one ends in the box are fixed with sleeve, when so scroll bar pipe (7) backrush drives the sleeve rotation, become only and between pole sleeve (22) and round metal bars (21), rotate, have certain resistance when rotating because of the effect of damping oil, so cause scroll bar pipe (7) the backrush speed can be slack-off relatively, the gauze backrush is gone into the yarn box and will slowly be regained, and the spring washer (17) on the Plastic cap (12) has caught on the cog rotating disk of shape of round metal bars (21) and also can damage or replace during fault the effect of unilateral bearing (19) one-directional rotation in metal bearing; When so having avoided general automatic invisible screen window to pack up straining beam rebound fast collision yarn box the sound and to prevent that straining beam collision yarn box from can crush operator's hand injured; This apparatus structure is special to have practicality, and has the function that improves the automatic invisible screen window safety.
