A pull rod structure, as shown in fig. 1-2, the pull rod structure 200 is matched with a main body used when the main body is installed, and the structure of the main body is not shown in fig. 1-2, because the pull rod structure 200 can be matched and applied to the main bodies with different models and structures.

An accommodating cavity for accommodating the pull rod structure 200 is formed in the main body, the accommodating cavity is provided with an opening communicated with the outside, and the pull rod structure 200 extends outwards through the opening.

The pull rod structure 200 includes: a pull rod 210, a spring 220 and a limit structure 300.

The pull rod 210 is assembled in the accommodating cavity and can be relatively retracted into or pulled out of the accommodating cavity, and the top of the pull rod 210 is exposed out of the accommodating cavity; the pull rod 210 is provided with a structure for limiting the pull rod 210 in the accommodating cavity and preventing the pull rod from being pulled out of the accommodating cavity completely.

The spring 220 is used for providing pushing force when the pull rod 210 is pulled out of the containing cavity, and when the pull rod 210 is in a containing state, the spring 220 is in a compressed state;

the limiting structure 230 is used for limiting the pull rod 210 when the pull rod 210 is in the storage state, so that the pull rod 210 cannot pop out of the accommodating cavity under the thrust action of the spring 220.

The limiting structure 300 comprises: a retaining hook 310 and a retaining block 320.

One end of the limiting drag hook 310 is limited in the housing 110, and is close to the inside of the accommodating cavity, i.e. away from the opening of the accommodating cavity, the limiting drag hook 310 comprises: an elongated body 311 and a hook 312 disposed at the end of the body 311, the open end of the body 311 being defined in the housing 110; from the view of fig. 7, the body 311 is in a natural state with no deformation in the unfolded state of the pull rod 210, and the body 311 is in a natural vertical direction as viewed in the orientation of fig. 7.

In a further embodiment, as can be seen from fig. 1, the open end of the body 211 forms a circular ring, and the inside of the body is formed with a structure for positioning the circular ring, so that the circular ring can be fixed inside the body and cannot move synchronously with the pull rod 210;

further, a stopper plate 111 is provided inside the main body to restrict the main body 311 from being positioned in a linear direction in which the tension bar 210 is pulled.

In a further embodiment, the stopper plate 111 has a notch formed therein for the body 311 to be inserted therein.

The stopper 320 includes: a first stopper 321 and a second stopper 322, the stopper 320 moving along with the movement of the pull rod 210.

As shown in fig. 2A, the first stopper 321 and the second stopper 322 are distributed in the extending direction of the pull rod 210, and the second stopper 322 is disposed on the first stopper 321, specifically, the second stopper 322 is close to the opening of the accommodating cavity, and the first stopper 321 is close to the inside of the accommodating cavity.

The first limiting block 321 is provided with a positioning groove 3210, an opening of the positioning groove 3210 corresponds to the second limiting block 322, and the positioning groove 3210 is set to play a limiting role when the pull rod 210 is stored; the elongated body 311 is linearly arranged along the stretching direction of the pull rod 210, and the positioning slots 3210 are not aligned with the elongated body 311, so that when the hook 312 is inserted into the positioning slots 3210, the elongated body 311 deforms.

Guide surfaces are arranged on the side surfaces of the first limiting block 321 and are a first guide surface 3211 and a second guide surface 3212, and the first guide surface 3211 guides the hook part 312 to enter the positioning groove 3210; the second guiding surface 3212 guides the limit hook 310 to move in a biased manner when the hook 312 is disengaged from the positioning slot 3210;

a guide surface is also provided on the side surface of the second stopper 322, and the third guide surface 3221 is a third guide surface 3221, and the third guide surface 3221 guides the hook 312 to disengage from the positioning groove 3210.

As shown in fig. 3-7, to further illustrate the limiting principle of the limiting structure 300, for convenience of description, the directions shown in fig. 3-7 are used to represent up, down, left and right for description. In order to more clearly show the operation principle of the drawbar structure 200, the main body 400 is represented by a rectangular wire frame in fig. 3-7, and the wire frame is used to show the relative position between the drawbar structure 200 and the main body 400 when moving, and does not represent the specific structure of the main body.

In fig. 3, at this time, the pull rod 210 is in a storage state, in this state, the hook 312 is snapped into the positioning slot 3210, and under the elastic force of the spring 220, the pull rod 210 has a tendency of popping up vertically, and the stop block 320 moves along with the pull rod 210, so that the stop block 320 also has a tendency of popping up first, and thus, the hook 312 is stably limited in the positioning slot 3210. Since the positioning slot 3210 is not aligned with the body 311, as can be seen from fig. 3, in this state, the body 311 is deformed and shifted to the right, so that the body 311 has a biasing force for moving to the left.

When the pull rod 210 needs to be pulled out of the accommodating cavity, firstly, a force is applied to push the pull rod 210 into the accommodating cavity, that is, the pull rod 210 is pushed downwards by applying a force in fig. 5; as shown in fig. 4, in the process of pushing the pull rod 210 downwards, the stopper 320 moves downwards, the hook 312 gradually leaves the positioning groove 3210, and the hook 312 contacts the third guide surface 3221, and since the body 311 has a biasing force moving leftwards, the hook 312 moves leftwards and resets when contacting the third guide surface 3221; when the pull rod 210 is further pushed down, as shown in fig. 5, the hook portion 312 slides to the highest position of the third guide surface 3221 at the lowest position of the third guide surface 3221, that is, the hook portion 312 is guided away from the positioning groove 3210 by the third guide surface 3221, and finally, when the pull rod 210 is released, the pull rod 210 is ejected upward by the elastic force of the spring 220 to eject out of the accommodating cavity; as shown in fig. 6, during the process of ejecting the pull rod 210, the hook portion 312 abuts against the second guiding surface 3212, and moves downward relatively along the second guiding surface 3212, and during the process of moving downward, the hook portion shifts leftward, so that the restraining hook 310 has a rightward shifting force. As shown in fig. 7, when the pull rod 210 is fully extended, the position-limiting hook 310 is separated from the second guide surface 3212, and after the separation, the position-limiting hook 310 is restored, and the hook portion 312 is located below the first guide surface 3211.

When the slide bar 210 is retracted, as shown in fig. 7, it is pushed downward until the hook 312 contacts the first guiding surface 3211, and as shown in fig. 8, when the slide bar moves to the top of the first guiding surface 3211, the position-limiting hook 310 is deflected rightward by the resistance of the first guiding surface 3211, so that the position-limiting hook 310 generates a leftward deflecting force, and at the same time, the spring 220 is compressed.

As shown in fig. 9, the hook portion 312 is moved downward to separate from the first guide surface 3211, at this time, the position-limiting hook 310 acts on the side surface of the second position-limiting block 322 under the action of a leftward offset force, and if the downward acting force applied to the pull rod 210 disappears, the pull rod 210 moves upward under the action of the spring 220, the position-limiting block 320 moves upward, so that the hook portion 312 is clamped into the positioning groove 3210 for position limitation, and the pull rod 210 is positioned and stored, and returns to the storage state again, that is, the state shown in fig. 3.

The above principle clearly describes how the limiting structure 300 limits the retraction and extension of the drawbar structure 200.

In a further embodiment, the tie rod 210 includes: a top handle 211, a guide rod 212, and a stopper shell 213; the top handle 211 is fixedly connected with the limiting shell 213, so that the limiting block 213 moves along with the top handle.
