Description

A kind of ship's propeller

Technical field

The utility model relates to a kind of propellers, refer specifically to a kind of ship's propeller.

Background technique

Currently, ship's propeller is widely used to yacht, in operation at sea ship (such as weed-cutting launch) small hull, it is one The power device that kind driving hull advances.Ship's propeller is generally included positioned at the motor and blade of riser bottom and positioned at standpipe The propeller head of upper end, is equipped with the handle of controller and control in the shell on propeller head, standpipe generally by Hanger bracket is fixed on hull, and advance, retrogressing or the steering of hull are then realized by swing handle.

Existing hanger bracket has generally included hanger bracket ontology and support frame, and hanger bracket ontology is equipped with and can be fixed in Clamping device on hull, standpipe limit on the support frame, be located in hanger bracket ontology two that support frame is rotated by pin shaft One is provided between side wall, on support frame can be driven the retention bar that moving part drives and moves up and down, correspondingly, hanger bracket ontology Two sidewalls on it is corresponding offer the locating slot being caught in for above-mentioned retention bar, as Chinese patent Authorization Notice No. is Structure disclosed in " Portable marine propellor " of CN2535324Y, actuator among these are determined using upper end with button Position screw rod.Using such hanger bracket, structure is simple, easy to adjust.

In addition, being influenced by hull size and the variation of the depth in locating river etc., in use, it is often necessary to which adjusting pushes away Corresponding change will also occur for the angle between device blade and the water surface, the angle of this handle that operator is held.And because not The difference of same operator's use habit and the factors of height condition, this just needs the angle to the handle held also to make phase The adjusting answered, to obtain preferable usage comfort.For this purpose, people design the handle regulating device of propeller, as China awards Such device is disclosed in " the lever regulating device of boat propeller " that power notification number is CN202244055U, the device Snap onto the mode in the index hole on graduated disk with the convex grain on slide plate to realize lever angle has grade adjusting, thus to expire The requirement of sufficient operator.Although program structure is simple, firm position degree is still to be improved.

Utility model content

For the current state of the art, the technical problem to be solved by the utility model is to provide a kind of structures simply, behaviour Make more convenient ship's propeller.

Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of ship's propeller, includes position In the motor of riser bottom, positioned at the propeller head of standpipe upper end and the hanger bracket of installation, the shell on the propeller head The handle of controller and control is inside installed, the hanger bracket includes hanger bracket ontology, for supporting the standpipe again Support frame and hanger bracket ontology is fixed on the clamping device on hull, support frame as described above is rotationally located in the hanger bracket sheet One is provided between the two sidewalls of body, on support frame as described above can be driven the retention bar that moving part drives and moves up and down, described outstanding It is corresponding on the two sidewalls of hanger body to offer the multiple locating slots being caught in for the end of above-mentioned retention bar, it is characterised in that: There is the partition parallel with retention bar, the two sides of the support frame below the partition have on support frame as described above The long guiding hole that lower direction extends, the both ends of the retention bar are plugged in the long guiding hole, and the actuator includes The shaft being pivotally supported on the support frame two sidewalls below partition and the pressing plate being fixed in the shaft, described shaft one end It exposes to the side wall of support frame and becomes operating side, the pressing plate is then located at the top of retention bar and can rotate and energy with shaft It drives the retention bar to move down, the up-and-down rod across partition is fixed on the retention bar, under being cased on the up-and-down rod End offsets with partition, upper end is connected in the pressure spring of up-and-down rod.

In the above scheme, steady in order to exert a force, the U-lag passed through for the up-and-down rod is provided on the pressing plate.

In the above scheme, further improved to be, the through-hole passed through for standpipe, the standpipe are provided on support frame as described above It is coated with perpendicular shell, the recess portion of the through-hole position insertion for the support frame is provided on the side for erecting shell, the recess portion Top and bottom are equipped with the mounting hole worn for standpipe corresponding with through-hole.

Further improved to be in above-mentioned improvement project, the upper end of the perpendicular shell is supported by a main shaft, described Head shell, which is provided with, to be covered on the main shaft and is also equipped with head shell on the main shaft relative to the axis hole of perpendicular housing into rotation The ratchet that can be contained in the axis hole of the head shell, be provided on the side wall of the axis hole with the mutually perforative radial hole of the axis hole, A pawl is hinged with by pin shaft in the radial hole, while being equipped on the pin shaft and to make the end of the pawl always With being meshed trend with the ratchet and the torsional spring of head shell rotation with this structure can be with when handle can be prevented to push It is conveniently adjusted the angle of handle on demand.

It is preferred that being equipped with the axle sleeve for supporting the main shaft in the perpendicular shell, each extended in the two sides of the axle sleeve Out with the first supporting part and the second supporting part vertically perforated, the upper end of the standpipe is inserted into the vertical of first supporting part In perforation, it is inserted with the reinforcing rod of distribution parallel with the standpipe, in the vertical perforation of second supporting part to improve The intensity of perpendicular shell is also beneficial to the steady upright of standpipe.

When adjusting angle in order to ensure handle, head shell can be relative to standpipe flexible rotating, it is preferred that the main shaft On be also equipped with positioned at the ratchet two sides and the bearing that is adapted to the axis hole of the head shell.

Compared with prior art, it since the retention bar of the utility model limits in long guiding hole, can be carried out reliably Limit, and the shaft operating side of hanger bracket side is exposed to by operation and is moved down come easily band dynamic pressure plate pressure holding retention bar, So that retention bar is detached from from locating slot, therefore realize the angle tune of propeller using such structure with equally can be convenient Section.Angle by the way of ratchet and pawl come regulation handle relative to standpipe simultaneously, easily to obtain operational comfort, And firm position, it will not be allowed to rotate down because applying additional power to handle, while again due to handle and head shell It rotates together, does not influence the operation such as speed regulation of handle, be also convenient for whole installation and implementation.
