Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

As shown in fig. 1 to 6, a levelling rod receiver, includes box body 1, the articulated apron 2 that is equipped with in 1 top of box body, both sides all are equipped with L type lifter plate 3 in the box body 1, 3 back fixings of L type lifter plate are equipped with spur rack 4, spur rack 4 and spur gear 5, the suit of spur gear 5 is fixed in 6 surfaces of rotation axis, 6 outer ends of rotation axis and 8 one end fixed connection of rotatory handle.

Preferably, both ends of the rotating shaft 6 are mounted on the side wall of the box body 1 through bearings.

Preferably, the outer end of the rotating shaft 6 is also connected with a ratchet-pawl mechanism 7. As shown in fig. 5, when the rotation handle 8 is rotated counterclockwise by the ratchet-pawl mechanism 7, the rotation shaft 6 and the spur gear 5 rotate counterclockwise, so that the spur rack 4 can move upward, and when the rotation handle 8 is released, the rotation shaft 6 and the spur gear 5 do not rotate clockwise due to the unidirectional stopping characteristic of the ratchet-pawl mechanism 7.

Preferably, the ratchet-pawl mechanism 7 comprises a ratchet 7.1 fixed on the surface of the rotating shaft 6 in a sleeved mode, the ratchet 7.1 is matched with a pawl 7.2, the pawl 7.2 is hinged to the outer side wall of the box body 1 through a pin 7.3, the outer surface of the pawl 7.2 is connected with a fixing plate 7.5 through a compression spring 7.4, and the fixing plate 7.5 is installed on the outer side wall of the box body 1. As shown in fig. 5 and 6, when the ratchet wheel 7.1 rotates anticlockwise, the pawl 7.2 does not affect the rotation process, when the ratchet wheel 7.1 tends to rotate clockwise, the pawl 7.2 stops the ratchet wheel, and the ratchet wheel 7.1 can rotate clockwise only when the pawl 7.2 is manually lifted.

Preferably, vertical chutes 9 are formed in two sides of the L-shaped lifting plate 3, vertical slide rails 10 are fixedly mounted on the inner side wall of the box body 1, and the vertical chutes 9 are in sliding fit with the vertical slide rails 10. Through the cooperation between vertical spout 9 and the vertical slide rail 10, can be so that the lift process of L type lifter plate 3 is more steady.

The working principle of the embodiment is as follows:

when the leveling rod is stored in normal times, as shown in fig. 3 and 5, the cover plate 2 can be opened firstly, then the rotating handle 8 is rotated anticlockwise, the rotating shaft 6 and the straight gear 5 rotate anticlockwise, so that the straight rack 4 can move upwards to drive the L-shaped lifting plate 3 to move upwards, the L-shaped lifting plate 3 moves upwards to a position close to the top of the box body 1, two sets of the leveling rods which are bound can be directly placed on the L-shaped lifting plate 3 at the moment, the storage is easy at the moment, and the influence of the narrow environment of the box body 1 can not be caused; then, the pawl 7.2 is lifted, the rotating handle 8 is rotated clockwise, and the rotating shaft 6 and the spur gear 5 are rotated clockwise, so that the spur rack 4 can move downwards, and the L-shaped lifting plate 3 and the leveling rod are driven to move downwards together; after moving down to the right position, the cover plate 2 is covered; when the levelling rod needs to be taken out, the steps are repeated, the cover plate 2 is opened, then the rotating handle 8 rotates anticlockwise, the rotating shaft 6 and the straight gear 5 rotate anticlockwise, so that the straight rack 4 can move upwards, the L-shaped lifting plate 3 is driven to move upwards, the L-shaped lifting plate 3 and the levelling rod move upwards to be close to the top of the box body 1, the levelling rod can be directly taken out at the moment, the influence of the narrow environment of the box body 1 cannot be received, and the taking-out process is convenient.

The above embodiments are merely preferred technical solutions of the present invention, and should not be considered as limitations of the present invention, and the features in the embodiments and the examples in the present application may be arbitrarily combined with each other without conflict. The protection scope of the present invention shall be defined by the claims and the technical solutions described in the claims, including the technical features of the equivalent alternatives as the protection scope. Namely, equivalent alterations and modifications within the scope of the invention are also within the scope of the invention.
