Description
Technical field
The utility model relates to mechanical spring technical field, refers to a kind of spring integrated structure of rolling-type curtain especially.
Background technology
In the spring integrated structure of existing rolling-type curtain, although spring can make curtain produce the effect of retracting, but when the stroke of curtain of leaving behind is long, spring stress becomes large relatively, due to extension and spring at right angles or acute angle bend and arrange, the junction Material Strength of extension and spring is destroyed, therefore, when spring produces stretching by axostylus axostyle drives, the elastic force that spring itself produces will concentrate on the junction of extension and spring, thus easily there is the situation of fracture, and then cause curtain cannot smooth operation, simultaneously, the selection of spring is also comparatively limited to, the material rigid of spring must be considered, rupture to avoid spring.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of spring integrated structure of rolling-type curtain, to solve the problems of the technologies described above.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of spring integrated structure of rolling-type curtain, comprise: an axostylus axostyle, described axostylus axostyle is provided with a spring, one end of described axostylus axostyle is provided with the first spring connecting support, the other end of described axostylus axostyle is provided with the second spring connecting support, one end of described first spring connecting support rotates the head being combined in described spring, the other end of described first spring connecting support is fixedly located at a curtain scroll bar, one end of described second spring connecting support is combined with described axostylus axostyle, the other end of described second spring connecting support rotates the afterbody being combined in described spring.
The lateral wall of described first spring connecting support is provided with one first thread segment, the lateral wall of described second spring connecting support is provided with one second thread segment, and the described head of described spring and described afterbody two ends are separately fixed on described first thread segment and described second thread segment.
The described head of described spring and described afterbody two ends are fixed by welding with described first spring connecting support and described second spring connecting support connection.
The beneficial effect of technique scheme of the present utility model is as follows:
During due to spring stress, the elastic force that spring itself produces is transmitted on curtain scroll bar and axostylus axostyle by the first spring connecting support and the second spring connecting support, being conducive to avoiding spring when stretching, coming off separation from the first spring connecting support and the second spring connecting support.
Accompanying drawing explanation
Fig. 1 is the spatial structure decomposing schematic representation of the utility model embodiment.
Fig. 2 is the spatial structure combination schematic diagram of the utility model embodiment.
Embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As depicted in figs. 1 and 2, the utility model embodiment provides a kind of spring integrated structure 100 of rolling-type curtain, comprise: an axostylus axostyle 30, one end of axostylus axostyle 30 radially run through be provided with one first perforation 31, axostylus axostyle 30 is provided with a spring 40, first spring connecting support 50 is located at the other end that axostylus axostyle 30 is provided with the first perforation 31, and can on axostylus axostyle 30 transitional slide, and one end of the first spring connecting support 50 rotates the head being combined in spring 40, the other end of the first spring connecting support 50 is then fixedly located on curtain scroll bar, first spring connecting support 50 is a hollow sleeve, the lateral wall of the first spring connecting support 50 is provided with one first thread segment 51, and the head of spring 40 is fixed on the first thread segment 51, one end of first spring connecting support 50 radially extends annular and is provided with a ring protuberance 52, and run through on ring protuberance 52 and be provided with multiple through hole 53.
The other end of axostylus axostyle 30 is provided with the second spring connecting support 60, one end of second spring connecting support 60 is fixedly located at one end that axostylus axostyle 30 is provided with the first perforation 31, the other end of the second spring connecting support 60 rotates the afterbody being combined in spring 40, second spring connecting support 60 is also a hollow sleeve, corresponding first perforation 31 on the sidewall of the second spring connecting support 60 and be coaxially equipped with two second perforation 61, and by a fixture 62 simultaneously through after the first perforation 31 and the second perforation 61, and the second spring connecting support 60 is fixed on axostylus axostyle 30, and fixture 62 is a latch, the lateral wall of the second spring connecting support 60 is provided with one second thread segment 63 simultaneously, and the afterbody of spring 40 is fixed on the second thread segment 63.
Axostylus axostyle 30 is also provided with one first interlock sleeve 70, and can on axostylus axostyle 30 transitional slide, by multiple locking piece 71 by through hole 53, the first spring connecting support 50 is locked in the side of the first interlock sleeve 70, and locking piece 71 is a screw rod.One end that axostylus axostyle 30 is provided with the second spring connecting support 60 is provided with one second interlock sleeve 80, is disposed adjacent with the second spring connecting support 60 simultaneously.
The spring integrated structure 100 of rolling-type curtain is contained in the curtain scroll bar of rolling-type curtain by the first interlock sleeve 70 and the second interlock sleeve 80, and rotating shaft rod 30 drives spring 40 to carry out stretching and rotating, and when spring 40 is when stretching and rotate, itself can produce an elastic-restoring force, and curtain can be allowed to reach the effect of retracting by elastic-restoring force.Due to the head of spring 40, afterbody two ends are separately fixed on the first thread segment 51 and the second thread segment 63, when spring 40 is stressed, the elastic force that spring 40 itself produces is transmitted on curtain scroll bar and axostylus axostyle 30 by the first spring connecting support 50 and the second spring connecting support 60, simultaneously the first thread segment 51 and the second thread segment 63 can be in addition spacing fixing by spring 40, to avoid spring 40 when stretching, to come off separation from the first spring connecting support 50 and the second spring connecting support 60, user also can be fixed additionally by welding manner in the junction of spring 40 and the first spring connecting support 50 and the second spring connecting support 60, the bond strength of spring 40 and the first spring connecting support 50 and the second spring connecting support 60 can be increased further, so can reduce the restriction on spring 40 material selection and reduce the situation that fracture occurs spring 40, and then extend rolling-type curtain serviceable life.
It is more than preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
