Abstract
The sheared and combined rat guard is one kind of article to prevent rat from climbing across mooring line and consists of left main wall, right main wall, limiter, central shaft and operating rope. The central shaft makes the left main wall and the right main wall combined by self weight to form one circular body, and the operating rope in the outer edge is operated to alter the gravitational fulcrum to complete the opening and closing of these two main walls. The present invention is superior to traditional rat guard; has automatic locking function, reasonable structure, convenient operation and reliable use; and is suitable for ship mooring line of 6-12 inch diameter.
Description
One, technical field:
Scissors type rat guard of the present invention, relate to ship's fitments design and manufacturing technology field, be applied to boats and ships, it mainly acts on is to prevent and stop that mouse climbs up and over the ship mooring hawser, and final purpose is to prevent reliably and to stop that mouse goes on board or spread disease germs down and the plague along mooring cable.
Two, background technology:
The employed rat guard of existing domestic and international navigating ship, a kind of is lower open, no hawser latching device, be placed on and as easy as rolling off a logly on the mooring cable be blown off, waft and hang over gun wale, another kind adds that at the lower openings place button door seals its open section, this just must the very important person stand on the gun wale, go following button door is buckled with hand, and in practical operation, in most cases only can't finish this program with people's brachium, it is being opened wide, mouse in the same old way can be by open ports along mooring cable freedom boats and ships up and down as a result, and these rat guards perform practically no function.
On the other hand, run between backspring and the hull or two hawsers between spacing during less than the rat guard radius, rat guard just can't be placed on the mooring cable, both made to place and gone up, but the influence that is subjected to the tidewater fluctuation owing to boats and ships is moved, make above-mentioned two pitch smaller, at this moment rat guard is just squeezed bad easily, all this kind, illustrated that all existing rat guard structurally exists class-one defect, need us to develop the product that a new generation has practical value, to replace old rat guard with new theory.
Three, summary of the invention:
The novel designs theory of scissors type rat guard of the present invention is exactly to invent a kind of product that can effectively overcome above-mentioned defective and have practical value, develops scissors type rat guard of new generation.Its technology is to realize like this; Comprise left main body wall, right main body wall, the structure of limiting device is interior, it is characterized in that: by left main body wall, right main body wall two dull and stereotyped semicircles are combined into a circle by the center shaft activity of interior circular hole top, in the diameter of intracardiac circular hole be 80mm-97mm, move 10～30mm on the center of circle of the relative circle in the circular hole center of circle in it, the mutually internal round-formed off-centre of rat guard cylindrical, make open end L all the time below hawser, left side main body wall, right main body wall is combined into a circle by self gravitation, the opening and closing of two main body wall, being located at an outer peripheral operation rope change gravity fulcrum by manipulation finishes, the degree of two main body wall opening and closing is limited by limiting device, is applicable to 6-12 inch Cable rope for ship.
Implement above-mentioned technology, effectively object gravity and lever principle combination have been applied on the scissors type rat guard, abandoned the structural critical defect of traditional rat guard, the hawser that the design of its novelty not only is fit to plurality of specifications uses, and has a hawser auto lock function, behind the circular hole, hawser forms fully enclosed barrier one on every side in hawser embeds, and can prevent effectively and stop that mouse goes on board or spread disease germs down and the plague along mooring cable.This product structure is reasonable, easy to operate, use is reliable, has promotional value.
Four, description of drawings:
Main TV structure scheme drawing when Figure of description opens for scissors type rat guard of the present invention.
Wherein: circular hole, 6-hawser, 7-eyelet hole, 8-eyelet hole, 9-operation rope, L-open spacing in 1-left side main body wall, the right main body wall of 2-, 3-center shaft, the 4-limiting device 5-.
Five, the specific embodiment:
Below in conjunction with accompanying drawing scissors type rat guard of the present invention is further described:
See accompanying drawing 1, left side main body wall (1), right main body wall (2) connect into an integral body by center shaft (3) and limiting device (4), the edge of left side main body wall (1), right main body wall (2) top is provided with eyelet hole (7), eyelet hole (8), be connected with operation rope (9) between eyelet hole (7), the eyelet hole (8), limiting device (4) is located at the top of center shaft (3).
See accompanying drawing 1, place scissors type rat guard, the operation rope (9) of mentioning scissors type rat guard, left side main body wall (1), right main body wall (2) is that the axle center makes the L place open under external force with center shaft (3), its aperture is limited by limiting device (4), opening part puts down and embeds hawser (6), after hawser (6) enters interior circular hole (5), loosen operation rope (9), left side main body wall (1), right main body wall (2) is that the axle center closes up naturally with center shaft (3) under the self gravitation effect, and its closed degree is limited by limiting device (4), the operation rope (9) that will loosen then tie up in ship side be on the bell, promptly finished the placement program of scissors type rat guard.
See accompanying drawing 1, reclaim scissors type rat guard: need only up take advantage of a situation and mention operation rope (9), left side main body wall (1), right main body wall (2) are that the axle center makes the L place open under external force with center shaft (3), continue upwards to mention operation rope (9), hawser (6) promptly withdraws from along lower ending opening L in the circular hole (5) in the scissors type rat guard, has promptly finished the reclaimer of scissors type rat guard.
Claims (1)
1. the invention discloses a kind of novel scissors type rat guard, comprise left main body wall, right main body wall, limiting device, center shaft, operation rope structure, it is characterized in that: be combined into a circle by the center shaft activity of interior circular hole top by left main body wall, right main body wall two dull and stereotyped semicircles, in the diameter of intracardiac circular hole be 80mm-97mm, move 10～30mm on the center of circle of the relative circle in the circular hole center of circle in it, the mutually internal round-formed off-centre of rat guard cylindrical, the degree of two main body wall opening and closing is limited by limiting device.
