Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

Example 1

This embodiment provides a semitrailer angle lock, as shown in fig. 1, fig. 2, fig. 3 and fig. 4, including be used for with semitrailer carriage fixed connection's angle lock installation crossbeam, set up angle lock body 2, the vertical running through on the angle lock installation crossbeam angle lock body 2 and with angle lock body 2 normal running fit's locking lever 10, setting are in the tapered end 1 and the setting at locking lever 10 top are in a pair of handle locating plate 7 of the handle of locking lever 10 bottom, it is a pair of be connected with between the handle locating plate 7 and be used for rotating the handle 9 of locking lever 10.

The angle lock mounting beam is provided with a beam handle limiting opening 14 for holding the outer end of the handle 9.

A square connecting plate 8 for hanging the handle is arranged between the pair of handle positioning plates 7. The inner end of the handle 9 is sequentially provided with a square hole 13 for holding the square connecting plate 8 and a circular hole 12 for movably accommodating the square connecting plate 8.

One end of the square hole 13 is engaged with the circular hole 12, so that the square connecting plate 8 can enter the circular hole 12 from the square hole 13 and enter the square hole 13 from the circular hole 12.

The diameter of the circular hole 12 is larger than the width of the square connecting plate 8, so that the handle 9 is in rotating fit with the square connecting plate 8 at the circular hole 12.

Specifically, the square connecting plate 8 is provided obliquely on the pair of handle positioning plates 7 in a posture of high inside and low outside.

The bottom of the square hole 13 and the lock rod 10 is provided with a lock rod base 11, and the lock rod base 11 is provided with a limit pin shaft 6.

Example 2

The embodiment provides a semitrailer angle lock, and the difference of specific structure and embodiment 1 lies in: in this embodiment, in order to reduce the weight, the angle lock body 2 is provided with a deepened groove 5. The top of the angle lock body 2 is provided with an oblique angle 3. In order to reduce friction, a grease fitting mounting hole 4 is formed in the angle lock body 2.

During assembly, the angle lock body is clamped on the angle lock mounting cross beam, and locking and loosening of the angle lock are controlled through rotation of the handle.

Specifically, the utility model provides a semitrailer angle lock working procedure as follows:

when the handle is positioned in the limiting opening of the handle of the cross beam, the handle can automatically slide into the square hole at the tail end of the handle by means of the gravity of the handle. Due to the limitation of the square connecting plate, the handle cannot rotate up and down, and the handle cannot rotate left and right by matching with the shape of the limiting opening of the handle of the cross beam, so that the purpose of limiting the handle is achieved, and the condition that the position of the handle cannot be changed along with the vibration of a vehicle is ensured.

When the angle lock tapered end is rotated in need operation, the handle is pushed inwards into the circular hole at the rear end, the handle can be rotated upwards at the position, the handle is separated from the limiting opening of the beam handle, and when the handle is rotated to be horizontal, the handle can be rotated to realize the conversion of the working position of the angle lock.

After the conversion of the working position is completed, the handle enters the limiting opening of the beam handle, and the handle automatically slides into the square hole at the tail end of the handle by means of the gravity of the handle, so that the purpose of limiting is achieved.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that: modifications can still be made to the embodiments of the invention or equivalents may be substituted for some of the features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
