Abstract

The utility model relates to a device capable of preventing from being clamped and wound for a flagpole, comprising a support frame and winding wheels, wherein the support frame is formed by two parallel support plates which are mutually fixed, and the winding wheels are installed after opposite axle holes and are formed in the supporting plates. Each winding wheel comprises a winding wheel shaft and two annular winding wheel plates fixedly arranged on the winding wheel shaft, the winding wheel shaft is arranged in the relatively fixed axle hole of the support frame, and the two winding wheel plates are positioned on the inner sides of the two supporting plates. The winding end of a cord for hoisting a flag is wound on the winding wheel, and the other end used as a hoisting end is wound around a pulley on the top of the flagpole, and then, is used for tying the flag after penetrating out of a cord hole on the top of the flagpole. Afterwards, the bottom of the flag is provided with a winding ring in a winding way in order to be sleeved on the flagpole. The inner sides of the two supporting plates are provided with columnar spacing cylinders which respectively lean against the circular outer edges of the winding wheel plates tightly and are fixedly connected with the supporting plates. The interval between the edges of the inner sides of the two spacing cylinders and the outer edges of the winding wheel plates is smaller than the diameter of the cord, thereby preventing the cord from being clamped in the interval between the winding wheel plates and the supporting plates.

Description

Flagpole anti-sticking wiring device

Technical field

The utility model relates to a kind of flagpole annex, refers to that especially a kind of being used for just changeing that twining hoists a flag or reverse and loosen flagpole that stay cord lowers flag with anti-sticking wiring device to the stay cord on the flagpole.

Background technology

At present in the flagpole that uses, for the convenience of hoisting a flag, present flagpole all is provided with usually around wheeled wiring device, the wiring device that flagraising usefulness is set by the bottom at flagpole is just changeing hoists a flag or counter-rotating is lowered flag, the wiring device generally includes the stay cord around wheel and flagraising usefulness, flagraising is wound in this on wheel with the coiling end of stay cord, after the stay cord other end is walked around the pulley of being located at truck as lift side, fasten flag after passing the rope hole of truck, put around ring to be placed on the flagpole in the bottom part ring winding of flag then, rising, in the process of flag, shake handle or use motor to drive with hand around the wheel forward or reverse, by stay cord being wrapped in around the stay cord of taking turns or emitting winding, thereby realize the lifting of flag, the wiring device that flagpole uses, usually all be the support that has comprised that two stay bearing plates parallel and that interfix constitute, and behind the relative axis hole that forms on this two stay bearing plate, install around wheel, around wheel comprise around wheel shaft and two annular arrangements that on wheel shaft, install and fix around wheel plate, be installed on the support in the relatively-stationary axis hole around wheel shaft, two are positioned at the inboard of two back plates around wheel plate, in the operating process of reality, when needs are fallen national flag, need manually or use motor driven around the wheel counter-rotating, the stay cord that is wound on wheel is emitted, under some special situations, for example the external world is moist especially, or during sleety weather, national flag might occur is bonded on the flagpole or freezes on flagpole, if at this moment reverse fast around wheel, particularly under the situation for motor driven, because the stay cord tension that national flag can not in time descend the general who has surrendered to discharge, draw high and on wheel, to occur not tightly around the pine of twining around phenomenon around wheel shaft, this is must stop around the wheel counter-rotating, again main story is wound in stay cord on wheel shaft again around wheel, the wiring device of these present structures, owing between wheel plate and stay bearing plate, have the space, wiring can be snapped onto unavoidably when therefore under this kind situation, just turning around line in the space between wheel plate and stay bearing plate, to cause around the unsve fault of wheel apparatus around the chucking self-locking of the space between wheel plate and the stay bearing plate.

The utility model content

Technical purpose of the present utility model be for provide a kind of the wiring device around the wheel both sides position-limiting drum is set, thereby prevent that stay cord is entangled in the flagpole always locked around wheel plate and stay bearing plate bracket clamp with anti-sticking wiring device.

The utility model flagpole anti-sticking wiring device, the wiring device comprises the support that two stay bearing plates parallel and that interfix constitute, and behind the relative axis hole that forms on this two stay bearing plate, install around wheel, around wheel comprise around wheel shaft and two annular arrangements that on wheel shaft, install and fix around wheel plate, be installed on the support in the relatively-stationary axis hole around wheel shaft, two are positioned at the inboard of two back plates around wheel plate, flagraising is wound in this on wheel with the coiling end of stay cord, after the stay cord other end is walked around the pulley of being located at truck as lift side, fasten flag after passing the rope hole of truck, put around ring to be placed on the flagpole in the bottom part ring winding of flag then, this two stay bearing plates inboard is provided with columnar position-limiting drum, this two position-limiting drum is close to respectively around the wheel plate rounded outer edge and is provided with and captives joint with stay bearing plate, and this two position-limiting drums inside edge and the gap between the wheel plate outer rim are less than the diameter of stay cord.

Use in the anti-sticking wiring device at flagpole of the present utility model, described each position-limiting drum is that two semicircular structures combination backs form, and this two semicircular structure is captiveed joint with corresponding stay bearing plate.

Flagpole of the present utility model with anti-sticking wiring device in, described position-limiting drum is towards forming the invagination binding structure after the edge bending to the inside of the inboard side of wheel, the inner edge diameter of this invagination binding structure is less than around wheel plate rounded outer edge diameter.

Beneficial effect: flagpole of the present utility model has increased the position-limiting drum of above-mentioned cylindrical structure with anti-sticking wiring device, even therefore crossed loose phenomenon when should in the wheel Umklapp process, stay cord occurring, also can avoid making stay cord to snap onto between wheel plate and stay bearing plate, prevent to cause the phenomenon of chucking self-locking, thereby avoided the generation of fault, this flagpole is simple with anti-sticking wiring apparatus structure, has good stable, more user-friendly, significantly reduce the cost that the user uses.

For ease of explanation detailed content and the technology relevant, below describe with regard to conjunction with figs. now with the utility model.
