Detailed Description

The embodiments of the present invention will be further explained with reference to the drawings.

The embodiment is as follows:

as shown in fig. 1-5, steel pipe for draw-bar box, including suitcase body 1 and handle 2, handle 2 is fixed at the upper surface of suitcase body 1, a side fixedly connected with arm-tie 3 of suitcase body 1, the upper surface of arm-tie 3 is equipped with mounting panel 4, the bottom surface of mounting panel 4 is fixed with two steel pipe bodies 5 that are the symmetry and set up, inside inserting of bottom of steel pipe body 5 is equipped with two stopper 6 that are the symmetry and set up, fixedly connected with spring 7 between the face in opposite directions of two stopper 6, a side of stopper 6 is fixed with two connecting rods 10 that run through in steel pipe body 5, connecting rod 10 can remove in steel pipe body 5.

The working principle of the above technical scheme is as follows:

when the steel pipe body 5 that damages is being changed in needs, the connecting rod 10 application of force is handed to the accessible, make connecting rod 10 be close to form extrusion spring 7 shrink mutually, and can drive stopper 6 and establish of inserting of stopper 6 and dog 8 near mutually because connecting rod 10 removes, can hand connecting rod 10 at this moment and shift up in leading to groove 11, steel pipe body 5 will cancel the installation with arm-tie 3 afterwards, prevent that suitcase body 1 from receiving the impact force when the transport and lead to steel pipe body 5 to appear rocking or when damaging, inconvenient the change, lead to life and effect not good.

In another embodiment, as shown in fig. 3 and 5, a limiting rod 14 is disposed between the facing surfaces of the two connecting rods 10, a holding block 15 corresponding to the connecting rod 10 is disposed on one side of the limiting rod 14, and a threaded rod 16 threadedly mounted with the connecting rod 10 is fixed to the surface of the holding block 15.

After the installation is accomplished as needs, the handheld gag lever post 14 of accessible inserts between two connecting rods 10, gag lever post 14 will receive blockking of lug 9 this moment, can hand piece 15 drive threaded rod 16 and connecting rod 10 threaded installation afterwards, hand piece 15 will cooperate lug 9 to block gag lever post 14 this moment, gag lever post 14 will prevent that connecting rod 10 from rocking appearing when receiving collision or impact force afterwards, lead to steel pipe body 5 and arm-tie 3 dislocation, influence the result of use.

In another embodiment, as shown in fig. 2 and 3 and fig. 5, two through grooves 11 are symmetrically formed on the surface of the pulling plate 3, and the connecting rod 10 is located in the through grooves 11 to slide.

Through setting up connecting rod 10, be favorable to having increased the result of use, prevent that the user from when needing to change steel pipe body 5, being difficult to the operation, the accessible sets up connecting rod 10 application of force and drives 6 cancellations of stopper and 8 insert and establish, greatly increased the result of use.

In another embodiment, as shown in fig. 3, four stopper blocks 8 paired in pairs and located at two sides of the steel pipe body 5 are fixed in the pulling plate 3, and the limiting block 6 is inserted into the rectangular stopper block 8.

Through setting up dog 8, the effectual steadiness that has increased prevents that steel pipe body 5 steadiness is not good when changing the dismouting, leads to steel pipe body 5's use to feel not good.

In another embodiment, as shown in fig. 3 and 4, an operation groove 12 is formed in the limiting block 6, an insertion rod 13 located in the spring 7 is inserted into the operation groove 12, and the insertion rod 13 is used for preventing the spring 7 from being stressed and dislocated.

Through setting up inserted bar 13, be favorable to having improved the result of use, prevent that spring 7 from misplacing when the atress from appearing, lead to the effect of resetting not good to influence stopper 6's result of use.

In another embodiment, as shown in fig. 5, a protrusion 9 fixedly connected to the outer surface of the connecting rod 10 is disposed on one side of the limiting rod 14, and the protrusion 9 is in the shape of an arc block for preventing the limiting rod 14 from shaking.

Through setting up gag lever post 14, the effectual result of use that has increased prevents that it rocks to shovel when connecting rod 10 receives the impact force to appear, leads to connecting rod 10 to remove the steadiness that influences steel pipe body 5, the counterbalance of accessible gag lever post 14 to improve the steadiness of connecting rod 10.

In another embodiment, as shown in fig. 5, both ends of the position-limiting rod 14 are semi-arc-shaped, and the hand-held block 15 is spherical for limiting the position of the position-limiting rod 14.

Through setting up handheld piece 15, be favorable to having increased the result of use, prevent that gag lever post 14 from dislocating with connecting rod 10 when receiving blockking of lug 9 to the influence is to the spacing effect of connecting rod 10, and the handheld piece 15 of accessible blocks and improves the result of use.
