Description
Technical field
The utility model belongs to ship equipment accessory technical field, is related to a kind of machine outside, in particular to one kind is applied to
Propeller protective case in machine outside.
Background technique
Machine outside refers to the propulsion engine being mounted on the outside of hull, usually hangs on the outside of stern trimming flag, also known as outboard
Machine, it is the preferred power of personal amusement and recreation canoe that machine outside integrated level is high, installation is chosen simple, be also widely used in fishery,
Commercial operation, government's law enforcement access field, according to energy source difference, machine outside is divided into fuel oil and electric outboard motor.Outside conventional ship
Propeller its blade on machine usually all directly it is exposed in water, therefore when the sundries or water plant that have floating in water are constantly easy quilt
Water flow, which involves in propeller, damages blade, since revolving speed is very fast when the propeller on machine outside is run and torsion is big, especially
In some water in the case where someone, high-speed rotating propeller, which is easy to get to people, to cause casualties, and there are security risks.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, and providing one kind lossless can install
In the propeller protective case for playing the role of effective protection on machine outside propeller.
The purpose of this utility model can be realized by the following technical scheme: a kind of propeller guarantor applied in machine outside
Sheath, including the molding protective case ontology that symmetrically cooperates, the edge of the ontology have several screw holes, and described
The support plate for installation is provided at the top of body, the middle part of the ontology is horizontally disposed axle sleeve, and inside axle sleeve and supports
Plate is connected, which is characterized in that the card slot for being coupled clamping with propeller is offered on the inside of the support plate, it is described
The left and right sides of axle sleeve extends outward to form the connecting plate of arc respectively, and several circle one are provided between connecting plate described in two
The top of the retaining ring of formula structure, the retaining ring is connected with support plate, and bottom is connected with ontology bottom surface, and the section of the retaining ring is
Shuttle-type, and the diameter of retaining ring water inlet is greater than the diameter of its water outlet.
The advantages of this propeller protective case are as follows: the protective case is set to spiral shell by the card slot mutual cooperation installation card in support plate
It revolves on paddle, and realize lossless installation by screwing fastened by screw in screw hole, the transmission shaft on propeller is stretched at the top of support plate
Enter and be located in axle sleeve, blade is installed on end part of driving shaft and is located in retaining ring, and prevents water by connecting plate and retaining ring
In personnel injured by propeller, while being also possible to prevent the biggish sundries of volume or water plant is involved in propeller, further
, in order to reduce resistance when water flow circulation, reduce influence of the protective case to propeller propulsive efficiency, the section of retaining ring is design
For shuttle-type, and the diameter of retaining ring water inlet is greater than the diameter of its water outlet.
In a kind of above-mentioned propeller protective case applied in machine outside, support plate and axis are located on the ontology
The connectivity part of set offers inlet opening.The design of the structure cools down water flow to propeller inside from water inlet inflow.
In a kind of above-mentioned propeller protective case applied in machine outside, the quantity of the retaining ring is 2.
Compared with prior art, this propeller protective case makes protective case ontology or so cooperate lossless peace by the design of card slot
Loaded on playing the role of effective protection on propeller, and it is easy for installation, and make it to propeller by the design to retaining ring structure
Propulsive efficiency influence it is smaller.

Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, the propeller protective case that should be used in machine outside, including the molding guarantor that symmetrically cooperates
Sheath ontology 1, the edge of ontology 1 have several screw holes 2, and the top of ontology 1 is provided with the support plate 3 for installation, ontology 1
Middle part it is horizontally disposed have axle sleeve 4, and 4 inside of axle sleeve is connected with support plate 3, and the inside of support plate 3, which offers, to be used for and spiral shell
Rotation paddle is coupled the card slot 3a of clamping, and the left and right sides of axle sleeve 4 extends outward to form the connecting plate 5 of arc, two connections respectively
The retaining ring 6 of several circle integral structures is provided between plate 5, the top of retaining ring 6 is connected with support plate 3, bottom and 1 bottom of ontology
Face is connected, and the section of retaining ring 6 is shuttle-type, and the diameter of 6 water inlet of retaining ring is greater than the diameter of its water outlet.
It further describes in detail, in order to cool down water flow to propeller inside from water inlet inflow, support is located on ontology 1
The connectivity part of plate 3 and axle sleeve 4 offers inlet opening 7.
Wherein, the quantity of retaining ring 6 is 2.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
Although be used more herein ontology 1, screw hole 2, support plate 3, card slot 3a, axle sleeve 4, connecting plate 5, retaining ring 6, into
The terms such as water hole 7, but it does not exclude the possibility of using other terms.The use of these items is only for more easily describe
With the essence for explaining the utility model；Being construed as any additional limitation is disagreed with the spirit of the present invention
Back.
