Description

Technical Field

[0001] The utility model relates to the technical field of guide caps, in particular to a guide cap for ship nuts. Background Art

[0002] A guide cap is a device that is mainly used to guide the flow of fluid, reduce the friction resistance between the fluid and the hull, and improve the navigation efficiency of the ship. It can be installed at the front end of the propeller or other equipment to help the water flow transition smoothly and avoid turbulence, vortices, etc. that cause energy loss and vibration.

[0003] The utility model patent application document with the publication number of "CN211139632U" discloses a guide cap for a ship nut, including a mounting rod, a paddle mechanism, a nut, a guide cap mechanism, a sleeve, a collar, a guide cap body, a chute, a protective mechanism, a placement groove, a contact ball, a movable ball, a push rod, a piston cylinder, a spring and a conduit. The beneficial effect of the utility model is that the rotation of the mounting block drives the screw to rotate, the screw drives the nut to rotate, and the nut drives the sleeve to rotate. Under the action of centrifugal force, the sleeve rotates to make the movable ball rotate continuously in the chute, and the continuous rotation of the movable ball continuously squeezes a number of contact balls, so that the contact ball pushes the push rod, and the push rod moves in the piston cylinder to squeeze out the lubricating oil stored in the piston cylinder. The lubricating oil is squeezed out of the piston cylinder and enters the conduit, and finally reaches the inner wall of the sleeve along the conduit, and finally reaches the screw and the nut, so that it is convenient to protect the nut and the screw when in use, so that the normal operation of the ship can be finally guaranteed.

[0004] The guide cap for ship nuts disclosed in the above document has the following defects: when the technical solution is in use, since the nut is exposed to the outside, the multiple planes on the nut will affect the guide effect when the guide cap is guiding, thereby reducing the guide effect and having relatively low practicality.

[0005] It can be seen from this that the existing guide caps for ship nuts do not have better guide components, and it is necessary to improve the existing deficiencies and provide a guide cap for ship nuts. Utility Model Content

[0006] The utility model aims to provide a guide cap for a ship nut to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model discloses a guide cap for a nut of a ship, comprising a mounting rod, a threaded groove is provided on the peripheral side surface of the mounting rod, a mounting structure is threadedly connected to the outer surface of the threaded groove, the mounting structure comprises a nut, a circular hole, an elongated groove, a reset spring, a movable block, a sliding block and a clamping column, the outer surface of the threaded groove is threadedly connected to the nut, circular holes are provided on both sides of the nut, an elongated groove is provided on the front side of the mounting rod, the number of the elongated grooves is fixed to two, the elongated groove is connected to the circular hole, a reset spring is fixedly installed inside the circular hole, a movable block is fixedly installed on one end of the reset spring, a sliding block is fixedly installed on the peripheral side surface of the movable block, the number of the sliding blocks is fixed to two, the sliding block is slidably connected to the inner wall of the circular hole, and a clamping column is fixedly installed on one side of the movable block.

[0009] Furthermore, a paddle structure is provided on the peripheral side of the mounting rod.

[0010] Furthermore, the paddle structure comprises a mounting block and a propeller, the mounting block is fixedly mounted on the peripheral side surface of the mounting rod, and a plurality of propellers are fixedly mounted on the peripheral side surface of the mounting block.

[0011] Furthermore, a guide cap structure is provided on the outer surface of the nut.

[0012] Furthermore, the guide cap structure includes a guide cap body, a guide block, a hexagonal slot and a circular slot. The guide block is fixedly installed on the outer surface of the guide cap body, and the number of the guide blocks is fixed to four. A hexagonal slot is opened on one side of the guide cap body, and a circular slot is opened on the inner wall of the hexagonal slot, and the number of the circular slots is fixed to two.

[0013] Furthermore, the hexagonal slot is snap-fitted with a nut, and the two circular slots are snap-fitted with a post.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model pulls the two movable blocks to move so that the movable blocks squeeze the reset spring and move inside the circular hole and the elongated groove. At the same time, the slider moves in the slide groove inside the elongated groove. The movement of the movable block drives the clamping column to retract into the inside of the circular hole. Then, the hexagonal clamping groove on the deflector cap body is installed into the outer surface of the nut. When the circular clamping groove and the clamping column coincide with each other, the two movable blocks are released to allow the reset spring to rebound, thereby completing the installation of the deflector cap body. The installation is simple and quick, and the nut is avoided from being exposed to the outside to affect the deflection effect of the deflector cap, thereby increasing practicality.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
