Description

Technical Field

[0001] The utility model relates to the technical field of engineering vehicle handles, in particular to a mechanical structure of an engineering vehicle operating handle. Background Art

[0002] Engineering vehicles such as aerial work platforms and scissor lifts are one of the most common equipment in many industries. They are used to carry, stack, load and unload goods, improving the efficiency of cargo transportation. The driver controls the lifting operation by operating the handle in the cab.

[0003] In the related art, the operating handles of engineering vehicles such as aerial platforms and scissor lifts are often pulled and hit horizontally by operators during use, which can easily cause shaking and vibration during operation, seriously affecting the accuracy of the operating handles and thus affecting the lifting and lowering of the engineering vehicle's lifting platform; if used for a long time in an environment with poor working conditions, the handles will also be infiltrated with dust, cement, and acid and alkaline water, causing the handles to become stuck when swinging back and forth, affecting the service life of the handles. Utility Model Content

[0004] The purpose of the utility model is to provide a mechanical structure of an operating handle of an engineering vehicle to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A mechanical structure of an operating handle of an engineering vehicle, comprising:

[0007] A fixing seat, a mounting plate is provided on one side of the fixing seat, and a hollow chamber is formed between the fixing seat and the mounting plate;

[0008] a rotating shaft, the rotating shaft being disposed in the hollow chamber;

[0009] A vertical shaft, one end of which is connected to the rotating shaft, and the other end of which is passed through the mounting plate and extends outside the mounting plate;

[0010] A compression spring is sleeved on the vertical shaft, and a spacer ring is arranged on the top of the compression spring, and the spacer ring compresses the compression spring.

[0011] The mechanical structure of the operating handle of the engineering vehicle according to this solution has at least the following technical effects:

[0012] The mechanical structure of the operating handle of the engineering vehicle is achieved by arranging the rotating shaft in a hollow chamber formed by a fixed seat and a mounting plate, and connecting one end of the vertical shaft to the rotating shaft and the other end through the mounting plate, so that the vertical shaft of the operating handle structure is more stable during the swinging operation, and by arranging a spacer ring, the compression spring is compressed so that the compression spring is always in a compressed state, so that after the vertical shaft swings in any direction, the compression spring drives the vertical shaft to automatically reset, and under the traction of the compression spring, the operating handle is prevented from shaking left and right, thereby improving the accuracy of the handle during operation and ensuring the stability of the engineering vehicle during lifting and lowering operations; and the handle structure is more closed, effectively isolating the infiltration of dust, cement and acid-base water, avoiding the phenomenon of handle jamming due to the infiltration of dust, cement and acid-base water, and extending the service life of the operating handle.

[0013] As a further solution of the utility model: the diameter of the bottom of the spacer ring is greater than the diameter of the top of the spacer ring.

[0014] Since the diameter of the bottom of the spacer ring is larger than the diameter of the top of the spacer ring, the contact area between the bottom of the spacer ring and the compression spring is increased, and the compression force is more evenly distributed on the surface of the compression spring, reducing wear caused by excessive local pressure and extending the service life of the compression spring.

[0015] As a further solution of the utility model: a wear-resistant sleeve is also arranged on the vertical shaft, and the bottom of the wear-resistant sleeve is connected to the top of the mounting plate.

[0016] Since a wear-resistant sleeve is also provided on the vertical shaft, and the bottom of the wear-resistant sleeve is connected to the top of the mounting plate, the friction between the vertical shaft and the mounting plate can be effectively reduced, thereby improving the durability and reliability of the operating handle, reducing the vibration and noise caused by friction, and improving the stability of the operating handle.

[0029] like Figure 1-3The embodiment of the utility model shown is a mechanical structure of an operating handle of an engineering vehicle, comprising: a fixed seat 101, a mounting plate 102 is arranged on one side of the fixed seat 101, and a hollow chamber is formed between the fixed seat 101 and the mounting plate 102; a rotating shaft 103, and the rotating shaft 103 is arranged in the hollow chamber; a vertical shaft 104, one end of the vertical shaft 104 is connected to the rotating shaft 103, and the other end is passed through the mounting plate 102 and extends to the outside of the mounting plate 102; a compression spring 105 is sleeved on the vertical shaft 104, and a spacer ring 106 is arranged on the top of the compression spring 105, and the spacer ring 106 compresses the compression spring 105.

[0030] Specifically, the mechanical structure of the operating handle of the engineering vehicle is achieved by setting the rotating shaft 103 in a hollow chamber formed by the fixed seat 101 and the mounting plate 102, and connecting one end of the vertical shaft 104 to the rotating shaft 103, and the other end is passed through the mounting plate 102, so that the vertical shaft 104 of the operating handle structure is more stable during the forward and backward swinging operation, and by setting the spacer ring 106, the compression spring 105 is compressed, so that the compression spring 105 is always in a compressed state, so that after the vertical shaft 104 swings in any direction, the compression spring 105 drives the vertical shaft 104 to automatically reset, and under the traction of the compression spring 105, the handle is prevented from shaking left and right, thereby improving the accuracy of the handle during operation and ensuring the stability of the engineering vehicle during lifting and lowering operations; and the handle structure is more closed, which effectively isolates the infiltration of dust, cement and acid-base water, avoids the phenomenon of handle jamming caused by the infiltration of dust, cement and acid-base water, and extends the service life of the operating handle.

[0031] like Figure 1 and Figure 3 As shown, the diameter of the bottom of the spacer ring 106 is greater than the diameter of the top of the spacer ring 106 .

[0032] Specifically, since the bottom diameter of the spacer ring 106 is larger than the top diameter of the spacer ring 106, the contact area between the bottom of the spacer ring 106 and the compression spring 105 is increased, and the compression force is more evenly distributed on the surface of the compression spring 105, reducing wear caused by excessive local pressure and extending the service life of the compression spring 105.
