Description

Technical Field

[0001] The utility model relates to the technical field of rubber discs, in particular to a bidirectional manual winch. Background Art

[0002] The bidirectional manual winch has significant advantages. First of all, its bidirectional design gives it extremely high versatility, allowing it to not only easily cope with lifting work, but also effectively perform lateral stretching, greatly increasing the flexibility of the use scenario. Secondly, this design brings high efficiency. The operator can quickly adjust the working direction of the winch according to actual needs without tedious replacement or adjustment, thereby significantly improving work efficiency. Furthermore, the manual winch is usually compact, small, light, and easy to carry and install, which makes it easy to use in various environments, especially suitable for field operations or emergency rescue occasions.

[0003] In the process of implementing the solution, the inventors found that the following problems existed in the prior art and have not been well solved: although the traditional bidirectional rotating manual rubber reel contains a brake, the brake can only serve as a brake when the rope or wire is quickly loosened, and the bidirectional rotating rubber reel is very easy to turn in the opposite direction when rotating. The brake cannot brake the rubber reel when the rotation direction is reversed, resulting in unnecessary safety hazards. Utility Model Content

[0004] The main purpose of the utility model is to provide a bidirectional manual winch, which can effectively solve the problems in the background technology.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-4 As shown, a bidirectional manual winch comprises a U-shaped seat 1, one end of the U-shaped seat 1 is rotatably connected to a winding roller 2, both ends of the winding roller 2 are provided with driven wheels 3, the other end of the U-shaped seat 1 is rotatably connected to a rotating shaft 4, both ends of the rotating shaft 4 passing through the U-shaped seat 1 are fixed with handles 5, both ends of the rotating shaft 4 located at the position of the driven wheel 3 are fixed with driving wheels 6, a limiting steering device 7 is provided on the inner side wall of the U-shaped seat 1 at the position of one of the driving wheels 6, and the limiting steering device 7 comprises a fixing box 71, and the fixing box 71 is located at the position of the driving wheel 6. There is a movable groove 72, and the movable groove 72 is located at the position of the driving wheel 6 and is twisted with a movable tooth 73 through a torsion spring. The fixed box 71 is located above and below the position of the movable tooth 73 and has plate grooves 75. Baffle plates 74 are inserted and slidably inserted into the plate grooves 75. One end of the fixed box 71 located at the plate groove 75 is bored with a screw groove 76, and the other end of the fixed box 71 located at the plate groove 75 is bored with a slide groove 77. The screw grooves 76 are threadedly connected with adjusting screws 78, and the slide grooves 77 are inserted and slidably inserted with slide rods 79.

[0020] Specifically, the movable teeth 73 are meshed and connected with the driving wheel 6, and the driving wheel 6 is meshed and connected with the adjacent driven wheel 3.

[0021] Specifically, the plate grooves 75 are connected to the movable grooves 72, and the two baffles 74 are respectively located above and below the movable teeth 73. The upper or lower baffle 74 can be selected to be inserted into the movable teeth 73 for blocking according to the rotation direction.

[0022] Specifically, one end of the adjusting screw 78 passes through the screw groove 76 and is inserted into the plate groove 75 and is rotatably connected to the adjacent side wall of the baffle 74. One end of the sliding rod 79 passes through the sliding groove 77 and is inserted into the plate groove 75 and is fixedly connected to the adjacent side wall of the baffle 74, so that the rotation of the adjusting screw 78 can drive the baffle 74 to move through.

[0023] Working principle:

[0024] The limiting steering gear 7 is installed at the position of one of the driving wheels 6 on the inner side wall of the U-shaped seat 1. When the installation is completed and in use, it is set according to the required rotation direction of the handle 5. The limiting steering gear 7 contains two adjusting screws 78. The two adjusting screws 78 rotate under different required conditions to drive two baffles 74 to be inserted above or below the movable teeth 73. When the driving wheel 6 rotates, the movable teeth 73 can only rotate in the direction where no baffles 74 are inserted. When the rotation direction is reversed, the rotation of the movable teeth 73 will be blocked by the moved baffles 74. For example, after the upper baffle 74 is inserted above the movable teeth 73, the movable teeth 73 can only rotate downward. When it rotates upward, it will be blocked by the upper baffle 74. When the movable teeth 73 are blocked, the rotation of the handle 5 cannot drive the driven wheel 3 to rotate in this direction through the driving wheel 6, so that it can prevent the rotation direction from being reversed, and has a better protection effect.
