Abstract

The utility model discloses a lifting device of a sun umbrella, the lifting device is the square type frame which comprises a fixing plate and a bracket; a torsion spring seat is fixed on the riser of the bracket inside the frame, and the torsion spring tightly surrounds the torsion spring seat; the two ends of the torsion spring are provided with the pothooks; the big shaft of the reel surrounds the torsion spring; the pothooks at the two ends of the torsion spring extent from the hatch at the big shaft of the reel, the small shaft of the reel is connected to the hole of the fixing plate, and the small shaft is provided with an inside square hole. The spool movably surrounds the reel, and locks the hooks with the locking plates, and the cord is fixed onto the spool. During the application, no noise is produced; the self-locking at any position can be realized. The lifting device which is installed in the umbrella tube has the advantages of good integrated function, beautiful appearance and simple structure.

Description

A kind of parasol lowering or hoisting gear

Technical field

The utility model relates to a kind of parasol lowering or hoisting gear.

Background technology

At present, the parasol that uses in the outdoor leisure is bigger because of umbrella, generally need when opening or drawing in by mechanical lifting gear, the structure of original lowering or hoisting gear generally is to adopt ratchet mechanism to add crank handle, and the problem one of existence is that ratchet slips over the generation noise from ratchet in rotating; The 2nd, volume can not be installed in the umbrella pipe more greatly, is provided with separately and causes the umbrella pipe need divide two sections, the not attractive in appearance and bulk strength decline of outward appearance.

Summary of the invention

The utility model purpose is to provide a kind of parasol lowering or hoisting gear, the globality that guarantees the umbrella pipe can be installed, again noiselessness in the umbrella pipe.

For addressing the above problem, the technical solution of the utility model is: a kind of parasol lowering or hoisting gear, comprise rope, it is characterized in that: fixed head and support are formed a square shape framework, in this framework, the torsion spring seat is fixed on the support riser, torsion spring tightly is enclosed within on the torsion spring seat, its two ends have hook, and the big axle head of spool is enclosed within on the torsion spring, and torsion spring two ends hook stretches out from the big shaft end side opening of spool, the little axle head of spool is connected in the hole of fixed head, and on this little axle, be shaped on interior square hole, and reel is actively set on the spool and card is arranged with the torsion spring two ends and link up with and blocks, and lanyard is on reel.

Described spool is provided with the shaft shoulder at two intervals.

Described on the reel axis hole with the spool lower shaft on two ends shaft shoulder cooperation position at interval be provided with plastic bushing.

Described reel is provided with the circular retainer ring of stationary rope.

The beneficial effects of the utility model are: noiselessness during use, and adopt torsion spring to realize the self-locking locking of arbitrary position, be installed in good integrity in the umbrella pipe, specious, simple in structure.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1 is this practical general structure cross-sectional schematic.

1. umbrella pipes among the figure, 2. fixed head, 3. support, 4. torsion spring, 5. torsion spring seat, 6. spool, 7. screw, 8. plastic bushing, 9. reel, 10. retainer ring, 11. ropes, 12. screws, 13. screws.

The specific embodiment

As shown in Figure 1, fixed head (2) is fixed with two pieces of screws (13) with support (3) and is formed a square shape framework, and in this framework, torsion spring seat (5) is welded in the middle of support (3) riser, torsion spring (4) tightly is enclosed within on the torsion spring seat (5) and is used to compress, transmit moment of torsion, and its two ends have hook; (6) one of spools are that one of macro-axis is little axle, macro-axis is enclosed within on the torsion spring (4) for the pipe shape, torsion spring (4) two ends hook stretches out from the major part side opening, there have a screw (7) to pass support (3) riser to be fixing with spool (6) and torsion spring seat (5) along center line, little axle macro-axis relatively is the slender axles shape, and axle head is bearing in the hole of fixed head (2), is located at the two ends shaft shoulder at interval on this, and be shaped on interior square hole, match with shaking the hand; Reel (8) is actively set on the little axle of spool (6) and has card to stretch out between the hook of torsion spring (4) two ends from reel (9) wall, on reel (9) axis hole with the little axle of spool (6) on have two ends shaft shoulder cooperation position at interval to stud with plastic bushing (8), rope (11) is fixed on the retainer ring (10) on the reel (9).

In the use, this device is fixed in the parasol circular parachute pipe (1) with two screws (12) and fixed head (2), in being shaped on, the little axle of spool (6) on umbrella pipe (1) wall of square hole end correspondence a circular hole is arranged, when use with spool (6) in square hole match crank handle rotating scroll (6) time, one of torsion spring (4) two ends hook reel (9) card blocks and drives torsion spring (4) serves as that axle rotates together with torsion spring seat (5), and then rope (11) is wound on the reel (9).Tow (11) then can make reel (9) card block and drive torsion spring (4) and be pressed on the torsion spring seat (5), and generation rubs and automatically locks.

Claims

1. parasol lowering or hoisting gear, comprise rope, it is characterized in that: fixed head and support are formed a square shape framework, in this framework, the torsion spring seat is fixed on the support riser, torsion spring tightly is enclosed within on the torsion spring seat, its two ends have hook, the big axle head of spool is enclosed within on the torsion spring, torsion spring two ends hook stretches out from the big shaft end side opening of spool, and the little axle head of spool is connected in the hole of fixed head, and is shaped on interior square hole on this little axle, reel is actively set on the spool and card is arranged and torsion spring two ends hooks blocks, and lanyard is on reel.

2. parasol lowering or hoisting gear according to claim 1 is characterized in that: described spool is provided with the shaft shoulder at two intervals.
