Drawings
In order to more clearly illustrate the technical solution in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below. It is clear that the described figures represent only some embodiments of the invention, not all embodiments, and that a person skilled in the art can also derive other designs and figures from these figures without inventive effort.
FIG. 1 is an exploded view of a universal spring booster of the present invention;
fig. 2 is a schematic view of the installation of the universal spring booster of the present invention in a spring roller blind.
Detailed Description
The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor based on the embodiments of the present invention all belong to the protection scope of the present invention. In addition, all the coupling/connection relationships mentioned herein do not mean that the components are directly connected, but mean that a better coupling structure can be formed by adding or reducing coupling accessories according to specific implementation conditions.
Referring to fig. 1 to 2, the general spring booster includes a support tube 1, a spring 2 mounted on the support tube 1, and two joints 3 respectively fixedly connected to two ends of the support tube 1, one end of the spring 2 is connected to one of the joints 3, the other end of the spring 2 is connected to a driving wheel 5 for driving a winding drum, and the support tube 1 penetrates through the driving wheel 5. The spring 2 is a right-handed spring, and the present invention is mounted on the headpiece. When the joint 3 directly connected with the spring 2 is installed on the head, the head is pulled to rotate clockwise, the driving wheel 5 rotates clockwise along with the winding drum, and the spring 2 can provide torque force for the driving wheel 5 to enable the driving wheel 5 to have a tendency of rotating counterclockwise. When the spring 2 is needed to provide torque force in the opposite direction for the driving wheel 5, namely the braking head is rotated in the opposite direction, and the spring booster still can realize the rebounding function, the connector 3 which is not directly connected with the spring 2 is installed on the braking head to enable the braking head to rotate anticlockwise, the supporting tube 1 and the two connectors 3 rotate anticlockwise simultaneously, the driving wheel 5 also rotates anticlockwise along with the winding drum, and the spring 2 enables the driving wheel 5 to have the tendency of clockwise rotation instead of tightly holding the supporting tube 1 like the traditional spring booster, so that the driving wheel 5 cannot rotate.
Further preferably, a soft membrane is arranged between the spring 2 and the support tube 1, and the soft membrane is wrapped on the outer side of the support tube 1. In order to reduce noise generated by the contact of the spring 2 and the support tube 1 in the rotating process, a soft membrane is arranged on the support tube 1 to prevent the spring 2 from directly contacting the support tube 1.
In a further preferred embodiment, two rotatable wheels 4 are attached to each of the joints 3, and the wheels 4 are in contact with the inner side of the drum. The joint 3 is provided with an annular boss, one end of the joint 3, which is far away from the supporting tube 1, is provided with a limiting block, and a space for installing the rotating wheel 4 is formed between the boss and the limiting block. The utility model discloses do not have the one end with system head or system tail installation, also make unsettled one end can be through runner 4 and reel contact, in order to avoid the utility model discloses with the collision contact of reel. Preferably, the runner 4 is generally made of a material having a relatively low hardness to further reduce impact and operational noise during use. The boss and the limiting block only limit the axial movement of the rotating wheel 4, and the rotating wheel 4 is not rigidly fixed, so that the rotating wheel 4 can freely rotate.
Further as a preferred embodiment, a connection structure is arranged on an end face of the joint 3 far away from the support tube 1, the connection structure includes a recess arranged on an end face of the joint 3, and a cross section of the recess is rectangular. The utility model provides a general spring booster can install through coupling mechanism and make on the head or install and make the tail, has more mounting means.
Referring to fig. 2, a spring roll screen includes a system head, a system tail and a general spring booster, the system head and the system tail are respectively installed to an installation code, and the system tail is connected with the general spring booster. Be equipped with the through-hole on the installation sign indicating number, the inboard of through-hole is equipped with interior tooth portion, the system tail is including system tail lid and the main part axle that runs through system tail lid, the one end of main part axle is equipped with the outer tooth portion that can mesh with internal tooth portion. The universal spring booster is connected with the tail, so that the connection of the head is simple, and the integral structure of the spring roller shutter is simplified. Because the main body shaft of the tail making is meshed with the through hole on the mounting code, the main body shaft does not rotate, and the joint 3 connected with the main body shaft does not rotate.
In a further preferred embodiment, a protrusion is provided on the other end face of the main shaft, and the cross section of the protrusion is rectangular. The convex part of the main body shaft is matched with the concave part on the joint 3 to achieve the effect of connection and fixation.
While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
