Description

The present invention relates to the field of energy devices and in particular relates to a dust-proof energy device which is used for a flexible line.

State of the art

Currently, dust-proof devices are known. One of the devices is described in Chinese Patent Application WO2012CN75418CN.

In the area of an energy device, electrical equipment should be powered by a connection. For electrical equipment, a flexible line is suitable for twisting and use, and reduces line space.

However, such a line has operational difficulties when installed in the power unit. In addition, the rigid part of the plug is small in size to reduce the amount of twisting, which makes manual handling difficult. Meanwhile, to ensure the safety of the power unit, the power installation slot is provided with a liner to ensure connection strength.

The essence of the invention

The object of the present invention is to provide a dust-proof energy device for a flexible line which can overcome the above-mentioned difficulties of the present technology.

The dust-proof power unit for the flexible line includes the line itself being flexible and connected to the electrical device with the attachment plug at the back. The attachment plug is fitted to the electrical cable holder and is used to connect the power supply. The power unit has a stand and a drive motor mounted on the left side of the stand. The propeller driven by the drive motor has an end that is pivotally mounted on the longitudinal plate of the right side of the rack. The screw is aligned with the movable wedge block to make the upper half of the movable wedge block slidably aligned with a guide groove mounted in the transverse support between the right longitudinal plate and the left side of the rack and the wedge surface of the lower for the clamping unit to use sliding fitting between the right sliding curvature and the right sliding gutter in the transverse sliding block, and the left sliding curvature and the right sliding gutter in the sliding block, the wedge surface acting in a longitudinal direction. With the help of the lower half of the clamping unit slidably mounted on the underside of the sliding support between the right-hand braking portion of the rack and the left-hand rack, the clamping block may pass through a flexible line insert between the right longitudinal plate and right braking portion and to release the flexible line provided between the clamping unit and the underside of the clamping unit. An elastic dust-proof coating is provided between the flexible line insertion slot and the flexible line and is secured to the inner wall of the flexible line insertion slot to prevent dust from exiting the stand through the gap between the flexible line and the flexible line insertion slot to the flexible line insertion slot. Multiple groups of transverse mounting holes are provided on the clamping unit to clamp the longitudinal drive rod in variable horizontal positions, the longitudinal drive rod being connected to the left side of the movable wedge block to transversely move the clamping unit across the sliding side of the sliding support longitudinal panels on the right side and rack on the left. In this way, the compressed flexible line can be pulled so far that the fastening pin can be inserted into the cable holder. The first upper pressure spring is mounted on the lower sliding support to press the transverse sliding block toward the right longitudinal plate. A second upper pressure spring is mounted on the lower sliding support to press the lower half of the clamping unit toward the right side of the braking portion. The swiveling cover plate is pivotally mounted on the outside of the right side of the longitudinal plate to close and open the flexible line insertion slot.

In the present invention, the drive motor causes the movable wedge assembly to move. When the clamping unit is pushed by a movable wedge block, the flexible line may be gradually pressed against the underside of the clamping unit so as to occupy a precise position towards the wire holder. With the longitudinal drive rod, this position can be individually adjusted upwards, the relative sliding length of the movable wedge block on the clamping block can be adjusted according to the different diameter of the flexible line so as to achieve an appropriate amount of clamping movements. In addition, with this longitudinal drive rod, the movement of the elastic component caused by the elastic force can be overcome by the drive motor. In this way, a flexible line that has been precisely positioned and clamped can gradually come closer to the wire holder and the retaining pin can be inserted into the wire holder. The entire power unit uses two systems and a corresponding spring to guarantee sufficient spring pressure from the top during longitudinal clamping so that the clamping block slides along without lateral displacement. The upper pressure of the spring is finally maintained on the right side of the longitudinal plate and on the right side of the braking part.
