Description

Technical Field

[0001] This utility model relates to the field of hand crank technology, and in particular to a portable manual brake fastener hand crank. Background Technology

[0002] A manual brake is a device that achieves braking function through manual operation. It is typically used in braking systems requiring manual control. Braking force is usually provided through hand cranks, foot pedals, or other forms of manual input. In railway systems, especially on some older freight cars or manually operated trains, manual brakes are used for manual braking. Operators control the braking device's activation and deactivation using hand cranks, levers, or other methods to ensure train stability during or after stopping.

[0003] Most hand cranks nowadays have a Z-shaped bend, which makes them difficult to store and retrieve due to their irregular shape. They are also prone to snagging when handling or placing them. Furthermore, their length is not adjustable, requiring the carrying of multiple devices in different locations. Since most cranks are made of metal, they are heavy and inconvenient to carry.

[0029] Example 1

[0030] Reference Figures 1 to 2 This is the first embodiment of the present invention, which provides a portable manual brake fastener hand crank, comprising:

[0031] A connecting rod 100 is fixedly connected to one side of the connecting rod 100, and a mounting rod 102 is fixedly connected to one end of the hinge 101. A handle assembly 105 is provided on the outer surface of the mounting rod 102.

[0032] The telescopic mechanism 200 is disposed inside the connecting rod 100. The telescopic mechanism 200 includes an extension rod 201, which is slidably connected inside the connecting rod 100. One end of the extension rod 201 is connected to a sleeve head 206, and the other end of the extension rod 201 is provided with a locking block 204. The extension rod 201 is slidably connected inside the connecting rod 100.

[0033] Specifically, the two ends of the hinge 101 are rotatably connected by a pivot, the extension rod 201 can extend the length of the tool, and the handle assembly 105 is rotatably connected to the mounting rod 102, which can improve comfort during use.

[0034] When in use, first pull the handle assembly 105 to slide it away from the hinge 101 on the mounting rod 102. When the mounting rod 102 is straightened and perpendicular to the connecting rod 100, release the handle assembly 105 so that it fits onto the hinge 101, which will put the tool in the unfolded state. When the mounting rod 102 is rotated to be horizontal with the connecting rod 100, it is in the folded state. Pulling the extension rod 201 and engaging it with the connecting rod 100 via the locking block 204 can adjust the length of the device for easy storage or use.

[0035] Example 2

[0036] Reference Figures 3 to 4This is the second embodiment of the present invention. Unlike the previous embodiment, one end of the mounting rod 102 is fixedly connected to a baffle 103, and a first spring 104 is fixedly connected to one side of the outer surface of the baffle 103. One end of the first spring 104 is provided with a movable plate, and both the first spring 104 and the movable plate are provided on the outer surface of the mounting rod 102.

[0037] Specifically, the first spring 104 mainly provides elastic force to facilitate the movement of the handle assembly 105. The baffle 103 and the moving plate are slidably connected inside the handle assembly 105, reducing the resistance to the rotation of the handle assembly 105 while pushing the handle assembly 105 to move.

[0038] The handle assembly 105 includes a rotating handle 1051, one end of which is rotatably connected to a snap-fit ​​cylinder 1052. A ball ring 1053 is fixedly connected to one side of the rotating handle 1051, and one side of the ball ring 1053 is attached to the outer surface of the moving plate of the first spring 104. The snap-fit ​​cylinder 1052 has a groove inside, which is attached to the outer surface of the hinge 101. A hand guard 1054 is fixedly connected to one end of the outer surface of the rotating handle 1051. A slot 106 is formed on one side of the outer surface of the connecting rod 100, and the front end of the locking block 204 is attached to the inside of the slot 106.

[0039] Specifically, the slot 106 inside the snap-fit ​​cylinder 1052 is the same size as the hinge 101, so that the two can be tightly connected and reduce shaking. The ball ring 1053 can reduce friction and facilitate rotation when the handle 1051 is rotated. The ball ring 1053 can receive the force transmitted from the first spring 104, so that the first spring 104 can push the handle 1051 to move. The hand guard 1054 can play an anti-slip role and improve the grip comfort. The snap-fit ​​block 204 and the slot 106 can fix the extension rod 201 by snapping it together.

[0040] Furthermore, a storage groove 202 is formed on one side of the outer surface of the extension rod 201. A second spring 203 is fixedly connected inside the storage groove 202, and the rear end of the locking block 204 is fixedly connected to one end of the second spring 203. The front outer surface of the locking block 204 is set inside the locking groove 106, and the rear end of the locking block 204 is slidably connected inside the storage groove 202. A threaded sleeve 205 is rotatably connected to one end of the extension rod 201, and a threaded rod 207 is fixedly connected to one end of the sleeve head 206. One end of the threaded rod 207 is threadedly connected inside the threaded sleeve 205.

[0041] Specifically, the socket head 206 can be replaced by the threaded rod 207 and the threaded sleeve 205, so that multiple models of socket heads 206 can be carried during use, reducing weight.

[0042] In use, first pull the handle assembly 105 to move it downwards along the mounting rod 102 away from the hinge 101. Then, rotate the mounting rod 102 outwards until it is perpendicular to the connecting rod 100. Release the handle assembly 105 and use the thrust of the first spring 104 to engage the locking sleeve 1052 with the hinge 101, thus extending the tool. In the extended state, pull the extension rod 201 forward. When it reaches a certain position, the second spring 203 will push the locking block 204 into the slot 106, locking the extension rod 201. After adjusting the length, select the appropriate socket head 206. Insert the threaded rod 207 at one end into the threaded sleeve 205, and then rotate the threaded sleeve 205 to make the threaded rod 207 threadedly connected inside the threaded sleeve 205. This completes the installation of the sleeve head 206, which can then be used. If folding is required, first press the locking block 204 to retract it and unlock it. Then push the extension rod 201 to retract it into the connecting rod 100. Next, pull the mounting rod 102 to make the locking sleeve 1052 disengage from the hinge 101. Finally, push the handle assembly 105 to rotate it to a horizontal and parallel state with the connecting rod 100 to fold it up, making the tool easier to use.

[0043] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
