Abstract
The invention relates to a stop element for a blind, of the type that is used to prevent the blind from being inserted fully into the blind housing and, consequently, disengaging from the guides thereof. The inventive stop element is characterised in that it comprises a special construction consisting of a truncated-cone-shaped body, a washer and a screw. According to the invention, the threaded perforation is not a through hole, thereby preventing (i) the ingress of dirt and (ii) the screw from being oxidised by means of moisture.
Description
Goal of the invention
This present invention relates to a kind of retainer that is used for curtain, is used to prevent that whole curtain from entering blind box cover, because will cause curtain to break away from guiding piece.
Stop element for blinds is characterised in that to have a kind of specific structure, and described structure has frustum and packing ring and screw.
Retainer is characterised in that to have the threaded bores of closely-pitched (for example Hui Shi gas thread) in frustum.
This threaded bores is not a through hole, thereby can prevent that dust from entering and get rusty owing to steam causes screw.
The feature of this retainer is that also the screw that retainer is connected on this curtain plate is self-locking (antagonistic) with respect to threaded bores, thereby avoids screw loosening and because climatic factor and deterioration.
Background technology
The retainer that is used for curtain is known, it has cylindrical shape or conical in shape usually, and is equipped with panel beating with tapping screw (it has metric thread and is screwed in the threaded bores for above-mentioned purpose) and be arranged on packing ring between curtain plate (wherein retainer is assemblied in this curtain plate) and the head of screw.
Applicant of the present invention also has utility model ES 1037581U, and its claimed a kind of retainer that is used for curtain is characterized in that having special structure, and wherein this retainer injected body itself defines central, threaded.
Summary of the invention
This present invention includes a kind of retainer that is used for curtain, is used for avoiding curtain entirely to be wrapped in blind box cover, because will make curtain break away from guiding piece.
Retainer is characterised in that the special construction with frustum; Described frustum has two recesses at the base portion place at two ends, and has bigger threaded bores in inside, and this threaded bores has the screw thread (for example Hui Shi gas thread) of fine pitch or closely-pitched with suitable compound mode.Threaded bores is a blind hole, avoiding entering of dust and moisture, thereby protects this screw.
The white lock of this screw and this threaded bores (for example being the Hui Shi gas thread in the middle of this example) makes this screw can not become flexible, and keeps avoiding infringement.
Be provided with chip shield between head of screw and plate, be used for avoiding damaging plate when being screwed into screw, this packing ring has central recess simultaneously, is used for ccontaining head of screw.
Description of drawings
Below by not limiting the accompanying drawing of the preferred embodiments of the present invention, describe.
Fig. 1 is the exploded view of curtain retainer and end plate.
Fig. 2 is the elevation and the sectional drawing of retainer, has shown the aperture that is combined in the screw thread in the housing and does not lead to the outside.
The specific embodiment
As from the foregoing, the present invention includes retainer.
Fig. 1 has shown the retainer on the end that is set at the curtain plate, and it comprises frustum 1, screw 2 and intermediate gasket.
Frustum 1 is characterised in that to have recess 1.1 that is arranged in big base portion and the recess 1.2 that is arranged in less base portion; Define threaded bores 1.3 in described recess 1.1 and the middle section of recess 1.2 in frustum, the counter-rotating critical angle of attacking screw in vain in the angle of rifling of described threaded bores and the traditional retainer differs bigger for 4.85 °, thereby prevents that because repeated impacts (itself owing to rise the maloperation to this curtain causes when falling curtain) produces disadvantageous becoming flexible.
For this purpose, set up the appropriate combination between the middle footpath of screw thread 1.3.2 and corresponding screw 2, perhaps seek on the market on salely and can satisfy the screw that differs more condition with the counter-rotating critical angle, wherein the latter is comparatively actual and economical.Therein, diameter is that 5 millimeters 3.05 ° of Hui Shi gas thread and closely-pitched metric system screw especially can satisfy above-mentioned condition for 2.92 °, the angle of rifling of these two kinds of screws all differs more with the inversion limitation angle, therefore can bear continuous knocking and can not make screw loosening, simultaneously retainer is broken, and make whole curtain enter to be cushioned in the blind box cover that device limits.
Selected preferred embodiment comprises the Hui Shi gas thread, and its blind end 2.1 arrives or do not arrive the inside of inner recess, and the inside of wherein said inner recess is provided with periphery flange, and is positioned at the central authorities of the recess 1.2 of less base portion.
Except with the device of periphery flange 1.2.1 as connection outer body and internal whorl main body, also can use reinforcement 1.5 to connect alternatively.
In Fig. 2, the circular protruding arch branch in the recess 1.1 of the big base portion of threaded bores 1.3, by four radially reinforcement 1.5 divide into four sections 1.4, described four radially the aperture 1.3 of reinforcement and threaded 1.3.2 be equally spaced.
The medial surface of the recess 1.1 of big base portion has four vertical and equidistant half-cylindrical ribs 1.6.
Though in an embodiment of the present invention, four sections 1.4 are limited by four reinforcements 1.5 and four half-cylindrical ribs 1.6, but, just can use the said elements of other numbers (outside four) and do not depart from the scope of the present invention as long as both number is identical in use.
Therefore threaded bores 1.3 is sealing blind holes, can avoid the oxidation with screw of entering of dust.In addition, screw 2 might run through the blind end 1.3.1 of threaded bores 1.3, because its length is not more than the thickness that thickness that the length of threaded bores 1.3 adds packing ring 3 is added at least 6 millimeters plates.
Selectively, if the size of curtain and material property allow, the retainer assembly can not use packing ring 3, and is wherein just passable as long as the length of screw is no more than the length in aperture 1.3.
The influence that essence of the present invention is not changed by the aspects such as material, shape, size and structure of element; And,, can allow one of ordinary skill in the art to repeat to implement the present invention by the description of being carried out in nonrestrictive mode.
