Description

M250930 IV. Creation Instructions (1) [Technical Field to which the New Type belongs] This creation is related to a device used to wind up the pipeline, more specifically, particularly a method that can effectively expand the conventional spiral spring. Reduce the volume, and can slow down the automatic winding speed of the pipeline, making the pipeline winding more stable and safe pipeline retractor structure. [Previous technology] According to the general, most of the pipeline retractors are used for the extension of long-distance pipelines, so that the process of pipeline deployment and retraction can be simple for users.

In order to make it easier and less labor-intensive for pipeline deployment and winding, various pipeline retractors have emerged at the historic moment. The structure of the pipeline retractor 10 shown in the first figure mainly includes a hollow tank. The base body 11 of 111 has a fixed shaft 12 extending through the center of the base body 11 and a fixed disk 12 is provided with an inner spiral spring 13 and a disc-shaped rotating body which is synchronously pivoted. 14, the swivel body 1 4 is accommodated in the hollow space 1 1 1 in the base body 1 1, and the fixed shaft 12 is the rotation center. Since the two ends of the spiral spring 1 3 are respectively positioned on the fixed shaft 12 and the pivot end 141 of the swivel 14, so when the pipeline a arranged by the swivel 14 is stretched out from the outlet 16 by the cable routing mechanism 15 and drives the swivel 14 to rotate, the swivel The volute spring 13 pivoted inside the body 14 performs a tightening action and generates a restoring torsion force and is accumulated in the volute spring 1 3, and the peripheral surface of the rotating body 14 opposite to the base body 11 is provided with a number of The positioning groove 171 and the positioning member 17 of the stopper edge 1 7 2 are provided on the opposite base body 1 1 and can be independently pulled by the spring 181 Unidirectional rotation of the actuator 18 abuts the stop member 19 with a fastening member; when the outer pipe extends to drive a rotary swivel 14, and the positioning element

When the positioning slot 1 7 1 of 1 7 is rotated to the abutment member 18, the abutment member 18 can just stop against the positioning slot 17 1 so that the swivel body 14 can only rotate in one direction. When the locking member 19 is turned to lock with the stop edge 17 2, the swivel body 14 will stagnate and not rotate, and it will be used as the basis for the distance positioning of the extension pipe a. At a, you can turn the loosening buckle in the reverse direction of the fastener 19 to rotate the positioning member 17 on the swivel 14 to disengage from the abutting member 18, so as to make the spiral spring in a torsion state. The energy released by 13 acts on the swivel 14 and forces the swivel 14 to automatically perform a reverse rotation, and the abutment member 18 can slide on the peripheral surface of the positioning member 17 without falling. It enters the positioning groove 171 and affects the rotation of the swivel body 14, and at the same time, the pipeline a acts as a storage operator via the wiring mechanism 15 (as shown in the second figure). However, the pipeline retractor 10 directly utilizes the vortex spring 13 with a strong return torque to act on the swivel 14 to produce the effect of rapid automatic rewinding. Taking the pipeline of the water pipe as an example, the end of the pipeline is A harder and a weight sprinkler a 'member is connected, so when the spiral spring 13 releases the winding force instantly and the pipeline a rotates rapidly, the sprinkler a' member will generate unpredictable randomness. Bounce, there are doubts about touching or damaging the objects or people around the displacement path; therefore, how to take into account the safety of use under a strong winding structure is a matter of urgency. [New content]

In view of this, the author created a structural improvement of the pipeline retractor based on the long-term research and integration of various retractable structures, which is based on the use of the internal arrangement of the pipeline retractor.

Page 6 M250930 Fourth, the base plate of the creation description (3), so that the reel for the pipeline winding can be pivoted between the two base plates, and at the same time, the volute spring providing the reel winding power can be installed on the base plate. The outer wall of the base plate adjacent to the reel, and an engagement transmission mechanism is provided at the outer wall of the base plate, so that the engagement transmission mechanism can transmit the power between the reel and the volute spring, and at the same time provide the appropriate size of the reel when the reel is retracted. The purpose of resistance is not only to reduce the volume of the spiral spring, but also to slow down the speed of the reel winding pipeline. That is, the main purpose of this creation is to provide a structural improvement of the pipeline retractor. The meshing transmission mechanism of the pipeline retractor has the function of transmitting the power between the reel and the volute spring, and can also provide the reel. The proper spray resistance when winding the pipeline, compared with the conventional pipeline retractor structure, it can effectively slow down the rotation speed of the scroll when it is subject to the strong torsion of the spiral spring, and it can be elastically released by the spiral spring. In the final stage, the inertia rotation of the meshing flywheel gear set makes the vortex spring produce a torsional force with recovery, so that the winding operation of the pipeline can achieve a smoother and safer effect, and the automatic winding speed of the conventional pipeline can be avoided. Too fast and the objects at the end of the pipeline touch the damaged objects or hurt people.
