The utility model is further described below with reference to fig. 1-8 and the detailed description:

as shown in fig. 1-6, the embodiment of the utility model discloses a pull rod assembly with a storage function, which comprises a pair of telescopic pull rods 71, a pull rod handle 70 and a connecting frame assembly; the connecting frame assembly comprises a connecting frame 1, a button 2, a compression spring 3 and a torsion spring 4. The left and right ends of the connecting frame 1 are provided with a pull rod through hole 12, and a telescopic pull rod 71 is inserted therein. A box body 10 with an opening is integrally formed below the connecting frame 1, and a box cover 11 for closing the opening of the box body 10 is hinged to the bottom of the box body 10; the pull rod assembly is attached to the rear side wall of the trunk or the bag body. The opening of the case 10 is disposed away from the outside of the case or bag body so that it can be exposed to the trunk or bag. The user can access the article by opening the cover 11 from the outside without opening the trunk or the luggage. The torsion spring 4 is connected with the box cover 11 and the box body 10; the push button 2 is provided with a foot 20; the top of the connecting frame 1 is provided with a button groove 13 with an opening facing to the upper side, and a supporting leg hole 14 which is communicated with the button groove 13 and the inside of the box body 10 is arranged in the button groove 13; the button 2 is accommodated in the button groove 13, and the support legs 20 penetrate through the support leg holes 14 and are clamped with the box cover 10.

The embodiment discloses a hinge structure, which specifically comprises a connecting rod 5 for hinge, and two side walls of a box body 10 and a box cover 11, which are close to the bottom, are respectively provided with a hinge through hole 15. The torsion spring 4 is sleeved on the connecting rod 5, and the connecting rod 5 is inserted into the hinge through hole 15 and is hinged and fixed. The torsion spring 4 is formed by integrating two torsion springs and comprises a left spring body 40 and a right spring body 41. The arm of force on one side of the left and right spring bodies is a rod 42, and the arm of force on the other side is connected into a whole through a u-shaped rod 43. One side arm of the torsion spring 4 supports the inner side wall of the box body 10, and the other side arm supports the inner side wall of the box cover 11.

Further, a leg hole 14 is provided at the bottom of the button groove 13. The support leg 20 is arranged at the bottom of the button 2, the support leg 20 is provided with a clamping hook part 21, the top end of the box cover 11 is provided with a clamping hole 110, and the clamping hook part 21 is hooked and matched with the clamping hole 110. The bottom of the button groove 13 is provided with a spring column 17, one end of the compression spring 3 is sleeved outside the spring column 17, and the other end supports against the bottom of the button 2.

One end of the compression spring 3 supports against the button groove 13, and the other end is connected with the button 2. The button 2 of the present embodiment is configured to slide up and down in the button groove 13, so that the hook portion 21 can be engaged with or disengaged from the engaging hole 110, thereby opening and closing the opening of the case 10. Under the static state, the button 2 is under the elastic force of the compression spring 3, the clamping hook part 21 is clamped into the clamping hole 110, and the opening of the box body 10 is closed by the box cover 11. When the button 2 is pressed, the clamping hook part 21 is withdrawn from the clamping hole 110, and the box cover 11 automatically pops up under the action of the torsion spring 4, thereby being convenient and quick. In some embodiments, the button 2 may also be configured to slide left and right in the button slot 13 to achieve the engagement of the leg 20 with the lid aperture 110.

Furthermore, the bottom of the button 2 is also provided with an L-shaped limiting part 22, the limiting part 22 stretches into the button groove 13, and the transversely protruding part of the limiting part is in clamping fit with the button groove 13. The structure makes the combination of the button 2 and the connecting frame 1 more compact, prevents the button 2 from separating from the button groove 13, and secondly, the compression spring 3 can be kept in a compressed state, so that the whole structure is compact in connection, and the use experience is better.

Further, a pair of torsion spring columns 16 are arranged at the bottom of the inner side wall of the box body 10, which is far away from the torsion spring, and at the moment arm positions corresponding to the left and right spring body rod pieces 42.

As the box body is made of injection molding materials, the thickness of the box body is thinner. The torsion spring column 16 can play a role of a reinforcing rib, strength of the box body 10 at the supporting part of the arm of force is enhanced, abrasion of the box body 10 caused by the arm of force of the rod piece 42 of the torsion spring 4 is reduced, and service life of the box body 10 is prolonged. The guide rail 161 can restrict the movement of the arm of the torsion spring 4, thereby restricting the movable range of the torsion spring 4.

As shown in fig. 7, the present utility model discloses another embodiment, in which the bottom of the inner side wall of the box body 10 far from one side of the torsion spring is provided with an inverted U-shaped hole 18, the inner side wall of the box body 10 forms a hook portion 19 like a fishhook at the inverted U-shaped hole 18, the lever 42 of the torsion spring 4 is supported against the upper hook portion 19 by a force arm, and the end of the lever 42 can be penetrated out of the box body 10 through the hook portion 19. The effect of the hook 19 on limiting the movement of the arm of force of the torsion spring 4 is better than that of the above embodiment, and the tail end of the arm of force of the torsion spring rod piece 42 is sharper, and the hook 19 penetrates out of the box body 10, so that the abrasion of the inner side wall of the box body 10 can be avoided.

Further, as shown in fig. 8, in another embodiment, the lid 11 is provided with a data line hole 111 through which a data line can pass, so that a user can use the charger baby stored in the box body conveniently.

It will be apparent to those skilled in the art from this disclosure that various other changes and modifications can be made which are within the scope of the utility model as defined in the appended claims.
