Problems solved by technology

[0002] The lifting mechanism of existing known lifting mosquito net has a lot of, more representative has No. 96245927.5 patent, No. 88100560.6 patent, No. 97245992.8 patent, No. 01242473.0 patent, the common feature of these lifting mechanisms is to be called with a " rope wheel " or The noose wheel of the "wire winding coil" is used to wind the lifting rope called "lifting rope" or "guyline" to achieve the purpose of lifting the mosquito net, and its disadvantages are;
[0003] No. 88100560.6 patent, No. 97245992.8 patent and No. 01242473.0 patent's lifting mechanism are all electric, lack the landing self-stop device that automatically adapts to the mosquito nets of different heights, the user of No. 97245992.8 patent and No. 01242473.0 patent must manually stop, if negligence It may cause the lifting rope to be rewound back to the cable wheel and cause failure. The landing self-stopping device of No. 01242473.0 patent cannot automatically adapt to mosquito nets of different heights, and the commercialized electric lifting mosquito nets require automatic adaptation to different height requirements of different families.
[0004] No. 88100560.6 patent, No. 97245992.8 patent and No. 01242473.0 patent's lifting mechanism all lack flexible and reliable braking devices, and the frictional resistance of the sponge used for braking to the wire coil in the No. 88100560.6 patent also increases when exerting the braking effect The load of the motor itself will also wear out quickly and lose its effect. No. 97245992.8 patent and No. 01242473.0 patent do not mention the braking mechanism at all. automatic landing
[0005] When the mosquito net landed, the hoisting ropes of all hoisting mechanisms in the background technology were pulled out of the noose wheel by the self-weight traction of the mosquito net. A certain part of the mosquito net is accidentally supported or hooked by a foreign object and cannot be landed, or the lifting rope is separated from the mosquito net due to children playing and washing, so that the lifting ropes cannot be pulled out of the rope wheel synchronously. In this way, it is easy to cause the hoisting rope that has lost traction to loosen and come out of the rim groove of the cable wheel or be rewound back to the cable wheel to cause a "rope chaos" fault. The noose wheel is entangled and out of groove and loses the correct connection relationship with the noose wheel, so that the lifting mechanism cannot work normally

Embodiment 1

[0039] figure 1 Among them, the lifting mosquito net is mainly composed of a tent body 1, a bracket 2, a lifting rope 3, a pulley 4, and a rope wheel 5. The pulley 4 is installed on the bracket 2 above each traction point of the tent body 1, and any position in the bracket 2 Noose wheel 5 is housed, and the rim of noose wheel 5 should have groove, and the hole or the hook of connecting rope are arranged at the bottom of the groove, and one end of hoisting rope 3 is connected in the groove of noose wheel 5, and the other end is guided downwards with tent through pulley 4. 1 tow point connection.

[0040] In Figure 2.1, Figure 2.2, and Figure 2.3, the main parts of the lifting mechanism include lifting rope 3, pulley 4, rope wheel 5, motor 8, travel switch 9, contact 10 of travel switch 9, driven gear 12, output gear 13. Transmission shaft 22, center shaft 24, gear 25, clutch and braking device. The components that make up the clutch include the driven toothed plate 23, the dri...

Embodiment 2

[0044] Figure 4 Among them, the parts that make up the lifting mechanism include the central shaft 24 and the driven toothed disc 23, the driving toothed disc 26, the advancing and retreating screw 39, and the screw propelling spring 40 that are mounted in series on the central shaft 24 in sequence. The housing 30 has a septum, and the septum There is a screw hole 42 cooperating with the advancing and retreating screw rod 39, and there are braking teeth 31, return spring 32, hinge pin 33, and limit pin 34; And can rotate on the central axis 24, the driving toothed disc 26 is coaxially connected with the advance and retreat screw rod 39 and can rotate on the central axis 24 and move along the central axis 24, and the side of the driven toothed disc 23 facing the driving toothed disc 26 has An annular tooth surface, one side of the tooth surface is steep and the other side is a gentle slope; the side of the driving tooth plate 26 facing the driven tooth plate 23 has an annular ...

Embodiment 3

[0048] Such as Figure 9 As shown, the mosquito net lifting mechanism includes tractors 50a equal to the number of necessary traction points of the tent body 1, and each tractor 50a is respectively installed above each traction point of the tent body 1, and each tractor 50a includes a motor 8, A set of clutches, a cable pulley 5, and a hoisting rope 3 are connected according to Fig. 5.1, Fig. 5.2, and Fig. 5.3.

[0049] In order to ensure the braking effect and the smooth driving of the driving chainring 26 and to reduce the wear of the braking teeth 31 and the driving toothing 26, the clutch of this embodiment is Figure 4On the basis of the shown clutch, an intermediate toothed plate 44 and a separation spring 43 are added between the driven toothed plate 23 and the driving toothed plate 26 to obtain the clutches shown in Figure 5.1, Figure 5.2, and Figure 5.3. Figure 5.1 shows that the clutch is in the separation state. The schematic diagram of the state, Figure 5.2 is a s...

Abstract

The mosquito net elevator with clutch includes driver, rope twisting wheel and elevating rope and features the clutch between the driver and the rope twisting wheel. During raising the mosquito net, the driver is coupled via the clutch to the rope twisting wheel, so that the driving force of the driver is transferred to the rope twisting wheel to draw the net to ascend. During lowering the mosquito net, the driver is separated by the clutch from the rope twisting wheel, so that the wheel rotates alone and the net descend on its self weight. Therefore, the mosquito net elevator can be so designed that the net ascene speed is relatively low and the net descent speed is relatively high, and this results in low production cost and long service life of the mosquito net.
