Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Embodiments of the present application are described in further detail below with reference to the accompanying drawings. In view of the problem that the prior art handle system for turning a truck body is easy to interfere with other components when solving the difficult operation caused by improving the height change by extending the length of the handle, as shown in fig. 1, 2 and 4, the present application provides a handle system for turning a truck body, comprising: the device comprises a base 1, an outer tube part 3, a handle part 5 and a locking device 4; wherein,,

the base 1 is used for being assembled on the vehicle body 2. The outer tube part 3 is assembled on the base 1. The handle part 5 is partially movably arranged in the outer pipe part 3 in a penetrating way, and the handle part 5 can move along the outer pipe part 3 so as to increase or decrease the height of the handle part 5 from the ground. The locking device 4 is arranged in the outer pipe part 3, the locking device 4 is connected with the handle part 5, and the locking device 4 is used for being clamped with the outer pipe part 3 so as to limit the handle part 5 to move in the outer pipe part 3.

It will be appreciated that the telescoping handle assembly is capable of extending the range of use of the handle by telescoping, and is adaptable to different height vehicle types. The operator can not be influenced by the too high height of the automobile to turn over the cab. And the interference between the components is avoided while the use is improved, so that the space position is saved. The telescopic structure greatly improves the space utilization rate, and can not interfere with other components in a non-use state.

When in use, an operator can switch the locking state and the unlocking state of the locking device 4 to fix the handle part 5 or unlock the handle part 5. Further, when the handle portion 5 is not used, the locking device 4 in the initial position is switched to the locked state by moving the handle portion 5 to the initial position, so that the handle portion 5 is prevented from protruding to interfere with other members. When the handle part 5 is needed to be used, the locking device 4 is unlocked, after the handle part 5 is manually pulled to enable the movement of the handle part in the outer tube part 3 to reach a preset position, the locking device 4 is switched to a locking state again, so that the handle part 5 is locked at the position, the handle part 5 is convenient for an operator to use, after the handle part 5 is used, the locking device 4 is switched to an unlocking state again, the handle part 5 is moved to an initial position, and the locking device 4 is manually switched to the locking state again, so that the handle part 5 is prevented from interfering with other parts.

Further, as shown in fig. 5 and 7, the locking device 4 includes: a sleeve 41, a limit post 42 and an elastic locking part 43; wherein,,

the sleeve 41 is movably inserted into the outer tube 3, and one end of the sleeve 41 is connected with the handle 5. The limiting column 42 is movably arranged on the side wall surface of the sleeve 41 in a penetrating manner; the elastic locking portion 43 is assembled in the sleeve 41, the elastic locking portion 43 is connected with the limiting post 42, and the elastic locking portion 43 is used for driving the limiting post 42 to be clamped with the outer tube portion 3.

Specifically, the sleeve 41 is provided with an opening at one end and an end cover 413 at the other end, and the end cover 413 is connected to the handle portion 5. As shown in fig. 3, 7 and 8, the end cap 413 is shown connected to the lower handle portion 5 in actual use. In the orientation shown in the figures, the end cap 413 side of the sleeve 41 is located below the open side in use.

Preferably, the limiting post 42 is movably disposed on the side wall surface of the sleeve 41 along the radial direction of the sleeve 41, the limiting post 42 may extend out of the sleeve 41, and the outer tube 3 is provided with at least two limiting holes through which the limiting post 42 passes.

It will be appreciated that the snap-fit is completed when the portion of the stop post 42 extends beyond the outer tube portion 3 through the stop aperture, and the handle portion 5 associated with the sleeve 41 is locked due to the inability of the sleeve to move.

Specifically, as shown in fig. 5, 6 and 8, the elastic locking portion 43 includes: and one end of the first limiting spring 431 is assembled on the inner wall surface of the sleeve 41, the other end of the first limiting spring 431 is connected with the limiting post 42, and the first limiting spring 431 is used for driving the limiting post 42 to pass through the limiting hole.

Further, in order to better implement the return function of the first limiting spring 431, a slider 421 is disposed at an end of the limiting post 42 away from the limiting hole, and the slider 421 abuts against the first limiting spring 431.

The first limiting spring 431 always applies a driving force to the slide 421 to drive the slide 421 and the limiting post 42 to move toward the side wall surface of the outer tube portion 3. When the slide block 421 and the limit post 42 move with the handle in the outer tube portion 3 (i.e. in an unlocked state), the end of the limit post 42 abuts against the inner wall surface of the outer tube portion 3 under the action of the first limit spring 431 until reaching the limit hole position of the outer tube portion 3. Therefore, the distance between the limiting holes on the outer tube part 3 is the travel range of the handle part 5.

In some preferred embodiments, in order to ensure the range of movement of the limit post 42 along the radial direction of the sleeve 41 and the attitude during movement, the locking device 4 further comprises: and a limiting portion 44 connected to the slider 421, where the limiting portion 44 is used to limit the movement range of the limiting post 42 in the radial direction of the sleeve 41.

Specifically, as shown in fig. 9, two symmetrical sides of the slider 421 are respectively provided with a chute 422, and the side of the sleeve 41 is further provided with a through hole 412.

And the limiting portion 44 includes: a U-shaped limit plate 441, and a second limit spring 442, wherein,

the middle part of the U-shaped limiting plate 441 is connected with the bottom of the slide block 421 through a second limiting spring 442, two ends of the U-shaped limiting plate 441 are provided with a bayonet 443, the bayonet 443 passes through the through hole 412 on the side wall surface of the sleeve 41 and is clamped with the chute 422, and the bayonet 443 can move along the chute 422. The hole 412 has a larger diameter than the pin 443, and the pin 443 is movable in the axial direction (i.e., up-down direction) of the sleeve 41 in the hole 412, but is not movable in the radial direction (i.e., horizontal direction) of the sleeve 41.

In use, as shown in fig. 9, in the locked state, the retaining pin 443 is located on the side of the chute 422 close to the first limiting spring 431, that is, the locking point a of the chute 422 in fig. 9, where the retaining pin 443 abuts against the chute 422 to limit the limiting post 42 to continue to extend out of the outer tube portion 3.

When the stopper 42 is manually pressed from the outside of the outer tube part 3, the stopper 42 moves radially inward along the sleeve 41. (i.e., horizontally moves to the right in fig. 9), at this time, since the retaining pin 443 cannot move radially along the sleeve 41, but only moves to the unlocking point b along the chute 422, the retaining pin 443 again abuts against the chute 422 after reaching the unlocking point b, and at this time, the retaining pin 443 is used to limit the limit post 42 to continue to retract into the sleeve 41. At this time, since the U-shaped limiting plate 441 is connected to the bottom of the slide 421 through the second limiting spring 442, the second limiting spring 442 is stretched when the locking pin 443 moves from the locking point a to the unlocking point b, and since the limiting post 42 can only move along the radial direction of the sleeve 41, the second limiting spring 442 also applies a restoring force to the limiting post 42 and the slide 421 to drive the limiting post 42 back to the locking point b.

Preferably, as shown in fig. 5, the sleeve 41 is provided with an opening slot 411, and the opening slot 411 is used for the limit post 42 to pass through, and is convenient for an operator to assemble the second limit spring 442 inside the sleeve 41.

In some embodiments, as shown in fig. 2 and 4, the outer tube portion 3 includes two tube bodies 31, and one locking device 4 is disposed in each tube body 31. The handle portion 5 is U-shaped as a whole, and the handle portion 5 is inserted into one pipe 31 respectively. Therefore, the operator can pull the body 2 downwards by holding the middle part of the handle 5, and after the body 2 is turned back to the normal position, the operator pushes the handle 5 to the initial position and locks the handle by the locking device 4, so that the handle 5 can be prevented from interfering with the mud guard 6.

Further, a slip-proof pad 51 is provided in the middle of the handle 5 to facilitate the operator to hold the handle for pushing or pulling.

The specific use is as follows:

s1, when the locking device 4 is in an initial locking state, the handle part 5 is located at an initial position.

S2, unlocking the handle part 5 by using the locking device 4: only the stopper post 42 of the locking device 4 needs to be pressed so that the stopper post 42 is retracted into the outer tube portion.

S3, pulling the handle part 5 to extend out of the outer tube part 3 until reaching the position of the preset limiting hole, and enabling the limiting post 42 to extend out of the other limiting hole of the outer tube part again to be locked again.

S4, after the use is finished, unlocking is performed according to the unlocking step, the handle part 5 is retracted to the initial position until the limit post 42 extends out of the initial limit hole.
