Description

Technical Field

[0001] The utility model relates to the technical field of sailing spinnakers, in particular to a telescopic device for a sailing spinnaker. Background Technique

[0002] A spinnaker is a special sail, usually used for upwind sailing of a sailing boat to improve the speed and performance of the sailing boat when sailing close to the headwind. When the spinnaker is not in use, the spinnaker is rolled up, that is, in a contracted state.

[0003] In the prior art, the spinnaker is often rolled up manually by manpower, which is relatively laborious and requires the operator to have certain experience, and thus has certain requirements for the operator. Therefore, a telescopic device for a sailing spinnaker is proposed to solve the above problems. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the utility model provides a telescopic device for a sailing spinnaker, which has the advantages of automatically rolling up the spinnaker and having low requirements for the operator, and solves the problems in the prior art that the spinnaker is often rolled up manually by manpower, which is relatively laborious and requires the operator to have certain experience, and thus has certain requirements for the operator.

[0006] (2) Technical Solutions

[0007] The technical solution of the utility model for solving the above technical problems is as follows: A telescopic device for a sailing spinnaker includes a mast, a spinnaker pole, and a forestay hanging between the mast and the spinnaker pole. An assembly seat is fixedly connected to the outer side of the forestay near its bottom end. A winding assembly located outside the forestay is provided on the outer side of the top end of the assembly seat. The bottom end of the assembly seat is fixedly connected to a housing located outside it. An installation chamber communicating with the housing is fixedly connected to the front side of the housing. A driving assembly extending into the housing is provided inside the installation chamber. A transmission assembly extending into the housing and meshing with the driving assembly is provided on the outer side of the bottom end of the winding assembly.

[0008] The beneficial effects of the utility model are as follows:

[0009] For this telescopic device for a sailing spinnaker, the driving assembly drives the winding assembly to rotate on the outer side of the forestay, and then rolls up the spinnaker hanging on one side of the winding assembly, so that the spinnaker is wound around the outer side of the winding assembly, and the rolling up of the spinnaker can be completed. It has the advantages of automatically rolling up the spinnaker and having low requirements for the operator.

[0010] On the basis of the above technical solutions, the utility model can be further improved as follows.

[0011] Further, the winding assembly includes a rotating base, a winding cylinder and a hanging ear. A rotating base adapted to the mounting seat is fixedly connected to the outer side of the front stay near its top end. The outer sides of the rotating base and the mounting seat are rotatably connected to the same winding cylinder located outside the front stay, and hanging ears are fixedly connected to the outer sides of both ends of the winding cylinder;

[0012] Further, the driving assembly includes a motor and a worm. A motor with an output end extending into the housing is provided in the installation cavity. The output end of the motor is fixedly connected to a worm rotatably connected to the inner side wall of the housing;

[0013] Further, the transmission assembly includes a sleeve and a worm gear. A sleeve extending into the housing is fixedly connected to the outer side of the bottom end of the winding cylinder, and a worm gear located in the housing and meshing with the worm is fixedly connected to the outer side of the sleeve.

[0014] The beneficial effect of adopting the above further solution is that when the motor is started, the output end of the motor drives the worm to rotate. Since the worm meshes with the worm gear, the worm gear is driven to rotate, thereby driving the winding cylinder to rotate outside the front stay through the sleeve, so as to wind the spinnaker hanging on one side of the hanging ear to the outside of the winding cylinder, and the winding of the spinnaker can be completed.

Detailed Embodiments

[0021] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] In the embodiment, it is given by Figures 1-5 A telescopic device for a sailing ball sail. The present invention includes a mast 1, a ball sail rod 2, and a forestay 3 hung between the mast 1 and the ball sail rod 2. An assembly seat 4 is fixedly connected to the outer side of the forestay 3 near its bottom end. A winding assembly 5 located outside the forestay 3 is provided on the outer side of the top end of the assembly seat 4. The bottom end of the assembly seat 4 is fixedly connected to an outer shell 6 located outside it. An installation bin 7 communicated with the outer shell 6 is fixedly connected to the front side of the outer shell 6. A driving assembly 8 extending into the outer shell 6 is provided inside the installation bin 7. A transmission assembly 9 extending into the outer shell 6 and meshing with the driving assembly 8 is provided on the outer side of the bottom end of the winding assembly 5.

[0023] The winding assembly 5 includes a rotating seat 501, a winding cylinder 502, and a hanging ear 503. A rotating seat 501 adapted to the assembly seat 4 is fixedly connected to the outer side of the forestay 3 near its top end. The rotating seat 501 and the assembly seat 4 are rotatably connected to the outer side of the same and located outside the forestay 3 with a winding cylinder 502. Hanging ears 503 are fixedly connected to the outer sides of both ends of the winding cylinder 502.

[0024] The driving assembly 8 includes a motor 801 and a worm 802. A motor 801 with an output end extending into the outer shell 6 is provided inside the installation bin 7. The output end of the motor 801 is fixedly connected to a worm 802 rotatably connected to the inner side wall of the outer shell 6.

[0025] The transmission assembly 9 includes a sleeve 901 and a worm gear 902. A sleeve 901 extending into the outer shell 6 is fixedly connected to the outer side of the bottom end of the winding cylinder 502. A worm gear 902 located inside the outer shell 6 and meshing with the worm 802 is fixedly connected to the outer side of the sleeve 901.

[0026] Start the motor 801. The output end of the motor 801 drives the worm 802 to rotate. Since the worm 802 meshes with the worm gear 902, the worm gear 902 is driven to rotate, thereby driving the winding cylinder 502 to rotate on the outer side of the forestay 3 through the sleeve 901, so as to wind the ball sail hung on one side of the hanging ear 503 onto the outer side of the winding cylinder 502, and the winding of the ball sail can be completed.

[0027] Working principle:

[0028] Step 1: Start the motor 801. The output end of the motor 801 drives the worm 802 to rotate. Since the worm 802 meshes with the worm gear 902, the worm gear 902 is driven to rotate accordingly.

[0029] Step 2: The worm gear 902 rotates, thereby driving the winding cylinder 502 to rotate outside the front stay 3 through the sleeve 901, so as to wind the spinnaker hung on one side of the hanging ear 503 to the outside of the winding cylinder 502.

[0030] Step 3: Finally, tie a rope on the surface of the spinnaker wound on the outside of the winding cylinder 502 to tighten the spinnaker.
