Description

Technical Field

[0001] The utility model relates to the technical field of clutch handles, in particular to a high-strength wear-resistant hand-forged clutch handle. Background Art

[0002] The clutch handle is an operating component in a mechanical device, mainly used to control the opening and closing of the clutch. The clutch handle is usually composed of multiple parts, including an inner handle, an outer handle, a sleeve, a set screw, a shaft, a compression spring, a connector and a cock, etc. The clutch handle is used in a variety of mechanical equipment, especially in occasions where the clutch needs to be operated frequently, such as motorcycles, automobiles, ships and other transportation vehicles, as well as some industrial equipment.

[0003] In the existing clutch handle design, the handle part adopts a detachable structure. This innovative design allows the clutch handle to be quickly and conveniently replaced or repaired when it encounters failure or wear, thereby improving the maintenance efficiency and service life of the equipment. However, the two detachable parts of the clutch handle are usually fixed by bolt connection during assembly. Although the bolt connection provides convenient disassembly and assembly, during actual use, due to external factors such as vibration and impact of the equipment, the bolts may become loose or even detached. This loosening or detachment will not only affect the stability and reliability of the clutch handle, but may also pose a potential threat to the overall performance and safety of the equipment. In view of this, we propose a high-strength, wear-resistant hand-forged clutch handle. Utility Model Content

A movable plate 36 that can be raised and lowered is slidably installed in the groove 34, and two limiting rods 37 are fixed on the movable plate 36. The bottom end of the limiting rod 37 passes through the bottom plate 35 and is slidably connected to the bottom plate 35, and the top end of the limiting rod 37 passes through the through hole 321 and is plugged into the limiting hole 22. A spring 38 is sleeved on the limiting rod 37, and the two ends of the spring 38 are respectively pressed against the bottom plate 35 and the movable plate 36.

[0032] In this embodiment, a through hole 23 is provided between the two limiting holes 22, and the through hole 23 passes through the fixing seat 2. The through hole 23 is provided to facilitate the insertion of tools such as a screwdriver, so that the movable seat 3 can be disassembled by means of tools such as a screwdriver.

[0033] In this embodiment, a strip groove 322 is provided between the two through holes 321, and the through hole 23 is connected to the strip groove 322. After a tool such as a screwdriver passes through the through hole 23 and the strip groove 322 and presses the movable plate 36, the movable seat 3 can be disassembled by pushing the movable plate 36 to move.

[0034] In this embodiment, the overall shape of the slot 21 is trapezoidal, and the overall shape of the plug block 32 is trapezoidal. When the slot 21 and the plug block 32 are plugged in, the fixed seat 2 and the movable seat 3 will not fall off.

[0035] In this embodiment, the movable seat 3 and the plug block 32 are integrally formed, and both the movable seat 3 and the plug block 32 are made of galvanized steel. The integrally formed movable seat 3 and the plug block 32 have better structural strength, ensuring the connection reliability of the movable seat 3 and the plug block 32, and the galvanized steel material has the advantages of corrosion resistance and high strength, ensuring the service life of the movable seat 3 and the plug block 32.

[0036] In this embodiment, a protrusion 30 is installed at the rear end of the movable seat 3, and a mold hole is opened on the protrusion 30. The protrusion 30 plays a role of limiting, ensuring that the movable seat 3 will not slip when the staff holds it.

[0037] In this embodiment, the fixing seat 2 and the protrusion 20 are integrally forged structures, and both the fixing seat 2 and the protrusion 20 are made of galvanized steel. The integrally forged fixing seat 2 and the protrusion 20 have better connection strength, and the galvanized steel material has the advantages of corrosion resistance and high strength, which ensures the structural strength and service life of the fixing seat 2 and the protrusion 20.

The rounded corner design can improve the comfort of use, and the coating surface is smooth, which has the effect of preventing hand wear.

[0040] It should be added that the coating in this embodiment is a metal-ceramic alloy applied to the surface of the fixed seat 2 and the movable seat 3 through surface engineering technologies such as supersonic flame spraying. The metal-ceramic alloy has high hardness and high wear resistance, can effectively resist hand friction, and extend the service life of the fixed seat 2 and the movable seat 3.

[0041] When in use, the user first aligns the insert block 32 with the slot 21 and inserts it, then presses the limit rod 37 downward, the limit rod 37 drives the movable plate 36 to move downward, the spring 38 is compressed, and when the limit rod 37 is retracted into the through hole 321, the user continues to push the insert block 32 to insert into the slot 21, and when the limit rod 37 moves to the limit hole 22, under the elastic action of the spring 38, the limit rod 37 is inserted into the limit hole 22, and the movable seat 3 is connected to the fixed seat 2;

[0042] When the movable seat 3 needs to be disassembled, the user first passes a tool such as a screwdriver through the through hole 23 and the strip groove 322 and squeezes the movable plate 36. The movable plate 36 moves downward and the spring 38 is compressed. At this time, the limit rod 37 disengages from the limit hole 22 and retracts into the through hole 321. Then the user pushes the movable seat 3 to one side. At this time, sliding occurs between the bottom end of the screwdriver and the surface of the movable plate 36. When the limit rod 37 moves to the lower side of the limit hole 22, the user takes out the screwdriver and pulls the movable seat 3 out of the fixed seat 2.

[0043] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
