Description

Technical Field

[0001] This utility model specifically relates to a quick-change hand-operated starter handle. Background Technology

[0002] As a starting component for small power equipment, the hand starter starts the equipment by manually pulling a rope, which drives the internal starting mechanism. It is widely used in agricultural machinery, garden tools, and small construction machinery. The handle, as the operating end of the hand starter, directly affects the convenience and reliability of the starting operation, and the stability of its connection with the rope is crucial to ensuring a smooth starting process.

[0003] In existing technologies, the connection between the handle and the pull rope of a manual starter is mostly a fixed installation structure. Common methods include directly tying the pull rope to the joint of the handle, or rigidly fixing the connector at the end of the pull rope to the handle using bolts, pins, or other fasteners. However, in actual use, the connection between the handle and the pull rope is a stress-concentrated area. The instantaneous pulling force during startup and repeated friction can easily cause wear, aging, or even breakage in this area, requiring regular replacement and maintenance of the handle or pull rope.

[0004] Due to the fixed installation design of existing handles, replacement requires the use of specialized tools such as wrenches and pliers to disassemble the fasteners or cut the binding ropes, and then re-bind or tighten them after replacing the new parts, making the operation process cumbersome. Especially for equipment maintenance at the work site, the complicated replacement process not only prolongs equipment downtime but also reduces work efficiency. In view of this, a quick-change hand-operated starter handle is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a quick-change hand starter handle to solve the technical problem mentioned in the background art, which is that most existing hand starter handles are directly fixed and installed. When the connection between the handle and the pull rope wears down and needs to be replaced, the replacement method is cumbersome and cannot achieve quick replacement, thus reducing work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-change hand-operated starter handle, comprising: The casing has a handle on the top. An opening lever is located at the bottom of the grip, and its end is hinged to the grip; Two sets of mounting bases are arranged opposite each other and slidably disposed within the housing. They are connected to the opening rod via a drive mechanism, which converts the rotation of the opening rod into the opening and self-locking of the two sets of mounting bases. The fixing base has two sets arranged opposite each other and connected to the two sets of mounting bases respectively. The opposite surfaces of the two sets of fixing bases are provided with fixing nails, and the two sets of fixing bases form a cavity for the pull rope to pass through.

[0007] In a preferred embodiment, the drive mechanism includes: A lifting seat is installed inside the housing in a height-adjustable manner, and a drive seat is provided at the bottom of the lifting seat; A propulsion assembly, disposed on the opening rod and connected to the drive seat, converts the rotation of the drive seat into driving the lifting seat to rise and fall; and An opening and closing assembly is disposed on the lifting seat and connected to the two sets of mounting seats to convert the lifting of the lifting seat into driving the two sets of mounting seats to open and lock.

[0008] In a preferred embodiment, the propulsion component includes: A first drive column is disposed on the opening rod; and A sliding frame is arranged on the lifting seat, and the first drive column is slidably engaged in the sliding frame.

[0009] In a preferred embodiment, the opening and closing component includes: The second drive column is provided in at least two sets, and is located at both ends of the drive seat respectively; and An inclined track is arranged on the mounting base, and vertical tracks are provided at both ends of the track. The second drive column is slidably engaged in one of the vertical tracks.

[0010] In a preferred embodiment, the housing is provided with a mounting cylinder, an adjusting bolt is slidably disposed inside the mounting cylinder, the adjusting bolt is screwed onto the mounting base, and its end is rotatably connected to the fixed base, the fixed base is provided with a positioning rod, and the positioning rod slidably passes through the mounting base.

[0011] In a preferred embodiment, a baffle plate is provided at the bottom of the housing, and an inlet pipe is provided on the baffle plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects: When the connection between the handle and the pull rope needs replacement due to wear, no additional tools are required. Simply rotating the opening lever triggers the drive mechanism, converting the rotation of the lever into the opening and closing action of two sets of mounting seats. Rotating the lever forward allows for quick removal of the old pull rope or damaged parts, while rotating it in the reverse direction causes the two sets of mounting seats to close, clamping the new pull rope onto the fixing seat. The drive mechanism has a self-locking function to ensure a secure connection after clamping, preventing loosening during startup. The fixing pins on the opposite sides of the fixing seat enhance the engagement with the pull rope, further improving connection reliability. This quick-change structure completely simplifies the replacement process, reducing the tedious operation of disassembling multiple fasteners or bolts to a single action, significantly shortening replacement time and greatly improving work efficiency. It is especially suitable for scenarios where equipment is frequently used and pull ropes are prone to wear, reducing equipment maintenance costs and downtime. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0016] Example: like Figure 1 , 2As shown, this utility model provides a quick-change pull starter handle, including a housing 1, a handle 2 at the top of the housing 1, an opening rod 6 at the bottom of the handle 2, the end of the opening rod 6 being hinged to the handle 2, two sets of oppositely arranged mounting seats 12 being slidably arranged inside the housing 1, the mounting seats 12 being connected to the opening rod 6 via a drive mechanism, the drive mechanism converting the rotation of the opening rod 6 into driving the two sets of mounting seats 12 to open and lock. The drive mechanism includes a liftable lifting seat 8 disposed inside the housing 1, a drive seat 10 disposed at the bottom of the lifting seat 8, a propulsion assembly disposed on the opening rod 6 and connected to the drive seat 10, the propulsion assembly converting the rotation of the drive seat 10 into driving the lifting seat 8 to rise and fall, the propulsion assembly including a first drive column 7 disposed on the opening rod 6, a sliding frame 9 disposed on the lifting seat 8, the first drive column 7 being slidably engaged within the sliding frame 9.

[0017] When in use, the device can be driven by pulling the handle 2 to move the pull rope 19. In the initial state, the two sets of mounting seats 12 are closed, and the lifting seat 8 is located at the highest point inside the housing 1. The first drive column 7 can be driven to move by rotating the opening rod 6. During the movement, the first drive column 7 can control the lifting seat 8 to descend by cooperating with the sliding frame 9.

[0018] like Figure 2 , 3 As shown, in this embodiment, the drive mechanism further includes an opening and closing assembly disposed on the lifting seat 8 and connected to the two sets of mounting seats 12. The opening and closing assembly converts the lifting of the lifting seat 8 into driving the two sets of mounting seats 12 to open and lock. The opening and closing assembly includes at least two sets of second drive columns 11, and the two sets of second drive columns 11 are respectively located at both ends of the drive seat 10. An inclined rail 14 is arranged on the mounting seat 12, and vertical rails 15 are provided at both ends of the inclined rail 14. The second drive column 11 is slidably engaged in one of the vertical rails 15.

[0019] During the lifting process, the lifting seat 8 can control the lateral sliding of the mounting seat 12 through the cooperation of the second drive column 11 and the inclined rail 14. Each of the two sets of mounting seats 12 has a fixed seat 16 on its opposite side, and each of the two sets of fixed seats 16 has a fixing nail 18 on its opposite surface. The two sets of fixed seats 16 form a cavity through which the pull rope 19 passes. When the second drive column 11 slides into the vertical rail 15, it can laterally lock the position of the mounting seat 12, thereby preventing displacement of the mounting seat 12. The pull rope 19 is fixed by the fixed seats 16, and the arrangement of the fixing nails 18 effectively prevents the pull rope 19 from falling off the fixed seats 16, improving the firmness of fixing the pull rope 19.

[0020] like Figure 2 , 3As shown, in this embodiment, a mounting cylinder 3 is provided on the housing 1, and an adjusting bolt 13 is slidably disposed inside the mounting cylinder 3. The adjusting bolt 13 is screwed onto the mounting base 12, and its end is rotatably connected to the fixed base 16. A positioning rod 17 is provided on the fixed base 16, and the positioning rod 17 is slidably disposed on the mounting base 12. The distance between the two sets of fixed bases 16 after they are closed can also be finely adjusted by rotating the adjusting bolt 13 with a tool, thereby accommodating pull ropes 19 of different thicknesses and effectively improving the applicability of the handle. Furthermore, a baffle plate 4 is provided at the bottom of the housing 1, and an inlet pipe 5 is provided on the baffle plate 4. The baffle plate 4 blocks the interior of the housing 1 to prevent external objects from entering the interior of the housing 1 and causing its internal structure to jam. The arrangement of the inlet pipe 5 facilitates the insertion of the pull rope 19 between the two sets of fixed bases 16.

[0021] The specific usage and beneficial effects of this utility model are as follows: When the connection between the handle and the pull rope 19 wears out and needs replacement, no additional tools are required. Simply rotating the opening lever 6 triggers the drive mechanism, converting the rotation of the opening lever 6 into the opening and closing action of the two sets of mounting seats 12. Rotating the opening lever 6 forward allows for quick removal of the old pull rope 19 or damaged parts, while rotating the opening lever 6 in the reverse direction causes the two sets of mounting seats 12 to close, causing the fixing seat 16 to clamp the new pull rope 19. The drive mechanism has a self-locking function to ensure a stable connection after clamping, preventing loosening during startup. The fixing pins 18 on the opposite side of the fixing seat 16 enhance the engagement with the pull rope 19, further improving connection reliability. This quick-change structure completely simplifies the replacement process, reducing the cumbersome operation of disassembling multiple fasteners or bolts to a single action, significantly shortening replacement time and improving work efficiency. It is especially suitable for scenarios where equipment is frequently used and the pull rope 19 is prone to wear, reducing equipment maintenance costs and downtime.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
