Description

Invisible retractable clothesline base

Technical Field

The utility model relates to a clothesline technical field, concretely relates to stealthy shrink clothesline base.

Background

The traditional clothesline is arranged between two wall surfaces for use, and the clothesline is suitable for a fixed and unchangeable space environment. At present, a clothes line capable of being stored can be stored in the base under the condition of nonuse, and the space occupied by the clothes line is avoided. When the clothes hanger is used, the clothes line is pulled out and fixed at other places, and clothes can be hung on the clothes line.

The above-mentioned collapsible clothesline still has the disadvantages: because the containing seat of the clothesline does not have the tightening function, when clothes are hung on the clothesline, the clothesline can be loosened along with the hung weight, so that the hung clothes slide together, and the clothesline is not beneficial to airing the clothes.

In addition, some bases are added with a fine adjustment function to overcome the problems, but the tightening and locking structures are complex, so that the production and manufacturing cost is high, the market occupation is not facilitated, and the competitive ability is not obvious enough.

Specifically, the spring is sleeved on the first fixing pin 7, and the spring and the ratchet 3 are both positioned between the wire roller 2 and the shell 1.

The locking assembly 5 comprises a torsion spring 8, a pawl 9 and a first rotation body 11 rotatably connected to a second fixing pin 10 inside the housing 1. The pawl 9 is fixed in first turning

body

11, 8 cover of torsional spring are located on the second fixed pin 10 and are connected with first turning body 11, through 8 drive of torsional spring first turning body 11 and pawl 9 are kept away from ratchet 3. In addition, first rotor 11 is equipped with second boss 13 to second fixed pin 10 is the fulcrum, and pawl 9, second fixed pin 10 and second boss 13 form three point support, form the lever, stir first boss 12 through second boss 13 so that first rotor 11 rotates, drive pawl 9 simultaneously and rotate and block in the ratchet 3, and whole simple structure produces the low degree of difficulty, is favorable to reducing production manufacturing cost.

As shown in fig. 2 and 4, the position limiting assembly 4 includes a first boss 12 and a second rotator 14 rotatably connected to a third fixing pin 15 inside the housing 1, and the first boss 12 is fixed to the second rotator 14. The limiting assembly 4 further comprises a spring 16 and a spring sleeve 17, the spring sleeve 17 is fixedly connected with the shell 1, one end of the spring 16 is connected with the second rotating body 14, and the other end of the spring 16 extends into the spring sleeve 17 and is hinged to the spring sleeve 17. The second rotating body 14 is provided with a push rod 18, one end of the spring 16 is provided with a spring seat 19, the spring seat 19 is provided with a groove, the tail end of the push rod 18 is matched with the groove and can rotate in the groove, the second rotating body 14 rotates clockwise or anticlockwise, the spring 16 is tightly pressed between the push rod 18 and the spring sleeve 17, and then the unlocking state that the pawl 9 is separated from the ratchet wheel 3 is kept or the locking state that the pawl 9 is clamped into the ratchet wheel 3 is kept. In addition, the second rotator 14 is provided with a handle 20 exposed out of the housing 1, the handle 20 drives the second rotator 14 to rotate so as to switch between the unlocking state and the locking state, and the second rotator 14 is further provided with a third boss 21 for limiting a rotation angle.

The working principle of the device is as follows:

s1: the clothesline is wound on the line roller 2, the tail end of the clothesline is positioned outside the shell 1, the shell 1 is fixed on a wall surface or other objects, then the handle 20 is manually broken to enable the second rotator 14 to rotate clockwise until the third boss 21 contacts with the side wall of the shell 1, at this time, the spring 16 and the ejector rod 18 form a certain angle, and then the spring 16 is tightly propped between the ejector rod 18 and the spring sleeve 17, so that the second rotator 14 cannot rotate any more. And the torsion spring 8 drives the first rotating body 11 and the pawl 9 to be far away from the ratchet wheel 3, and is in an unlocking state.

S2: the clothesline is pulled to extend out of the line roller 2 by overcoming the elastic force of the spring, the handle 20 is reversely pulled by hand after the clothesline is fixed, the second rotator 14 rotates anticlockwise until the first boss 12 and the second boss are pulled to rotate, at this time, the spring 16 and the ejector rod 18 form a certain angle, so that the spring 16 is tightly propped between the ejector rod 18 and the spring sleeve 17, and the second rotator 14 can not rotate any more. And the first rotating body 11 overcomes the torsion spring 8 to rotate and drives the pawl 9 to be clamped into the ratchet wheel 3, and is in a locking state. But the line roller 2 can rotate towards the direction of retrieving the clothesline to form unidirectional rotation locking. The clothesline is continuously retracted under the driving of the clockwork spring, so that the clothesline is kept in a tight state. Because the pawl 9 is clamped into the ratchet wheel 3, the line roller 2 cannot rotate in the direction extending out of the clothesline, and the clothesline cannot be pulled out even if the clothes are too heavy, so that the phenomenon that the clothes droop is reduced.

In the present embodiment, when the unlocked state and the locked state are switched, the end of the plunger 18 rotates in the groove of the spring seat 19, and the spring 16 is prevented from bending.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
