Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "upper surface", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

Referring to fig. 1-7, the present invention provides an embodiment: a power-assisted curtain pull rod comprises a support frame 1 wrapped outside pull beads, wherein one end of the support frame 1 is provided with an upper cover 4, and a pull bead groove 13 is also formed in the support frame 1; a sliding plate 3 is slidably arranged outside the support frame 1; wherein, the sliding plate 3 is sleeved outside the supporting frame 1; in addition, the slide board 3 is provided with an oval cross section for aesthetic purposes; one end of the sliding plate 3 is connected with a spring 5, and the other end of the spring 5 is connected with the upper cover 4; the sliding plate 3 is further provided with a switch 9, the switch 9 is further provided with a clamping groove 8, and the clamping groove 8 is clamped on the pull bead in the pull bead groove 13 after being pressed.

In conclusion, because the device wraps the exposed pull beads by using the support frame 1, the pull beads are prevented from dragging to influence the indoor environment; secondly, the pull beads are prevented from dragging and hooking indoor articles; thirdly, the problem that the pulled bead winds around the neck due to the fact that the bead is played by the child is avoided; meanwhile, the pull bead in the pull bead groove 13 is contacted by the push switch 9, and then the sliding plate 3 is slid, so that the pull bead can be driven to move in the pull bead groove 13, and the curtain can be descended or ascended.

In addition, when the switch 9 is in a free state, the spring 5 can drive the sliding plate 3 to reset, so that the sliding plate 3 slides again to drive the pull beads to move, the curtain is completely opened or closed, and the power assisting effect is realized.

In order to further facilitate the user to operate the switch 9, the switch 9 includes a first button 6 and a second button 7, and the first button 6 and the second button 7 are both provided with the clamping groove 8, and because two buttons are provided and designed side by side, the user holds the thumb of the sliding plate 3 to switch back and forth between the two buttons, which can drive the pull bead in the pull bead groove 13 to slide; for example, the first button 6 is pressed to contact with the pull bead in the pull bead groove 13, and then the slide plate 3 is slid, so that the pull bead can be driven to move in the pull bead groove 13; the curtain is driven to ascend or descend by the pull beads; conversely, the first button 6 is released, and the second button 7 is pressed to drive the pull beads in the pull bead groove 13 to move, so that the curtain can descend or ascend. When the two buttons are in a free state, the spring 5 can drive the sliding plate 3 to reset, so that the sliding plate 3 slides again to drive the pull beads to move, and the curtain is completely opened or closed.

Because the end of the support frame 1 far away from the upper cover 4 is also provided with the lower cover 2; therefore, the pull bead can be further wrapped in the support frame 1 by the lower cover 2, so that the lowest end of the pull bead is prevented from being exposed outside; meanwhile, the lower cover 2 is also internally provided with a roller 21, and when one end of the pull bead enters from one side of the roller 21 and then is led out from the other side of the roller 21; thus, the roller 21 and the pull bead are linked to reduce the friction force, so that the pull bead can smoothly rotate.

Since the lower cover 2 includes the first portion 20 and the second portion 22, the installation of the roller 21 is facilitated.

Wherein, the assembly of the lower cover 2 and the support frame 1 is convenient; the first part 20 and the second part 22 are provided with a first bolt 23 and a second bolt 24. A first bolt 23 on the first part 20 is connected with a first slot 10 arranged on the support frame 1; the first bolt 23 on the second part 22 is connected with the second slot 11 on the support frame 1; the second bolt 24 is connected with a third slot 12 arranged in the middle of the support frame 1.

On the basis of the above scheme, the sliding plate 3 is connected with one end of the spring 5 through a supporting column 31, and slides in the supporting frame 1 through a guide plate 30, so as to guide the sliding plate 3 to slide along the supporting frame 1. To ensure smooth sliding of the slide plate 3.

Usually, the pull beads are connected end to end, so that the upper cover 4 comprises an upper half 40 and a lower half 41, and an insert plate 42 and a third plug pin 43 are arranged on both the upper half 40 and the lower half 41; wherein the other end of the spring 5 is fixed on the third bolt 43, thereby facilitating the pull ball to pass through the lower cover 2 and enter the support frame 1.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and these embodiments are still within the scope of the invention.
