The specific meaning of the above terms in the present invention can be understood to be specific to those skilled in the art.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 3, a high-strength compression-resistant pull rod of a case comprises a movable rod 1 and a fixed rod 2, wherein the movable rod 1 and the fixed rod 2 form an expansion piece; the bottom of the fixed rod 2 is provided with a base 5, and the base 5 is used for being fixedly connected with the luggage body; the top of the movable rod 1 is provided with a handle 3, which is convenient for pulling the suitcase by hand.
The movable rod 1 comprises a hollow tube 101, the fixed rod 2 comprises a solid tube 201, and in the specific implementation, the hollow tube 101 is sleeved on the solid tube 201, so that the movable rod 1 can move up and down along the fixed rod 2.
Each surface of the outer wall of the solid tube 201 is provided with a plurality of groups of vertical raised strips 202; be equipped with cavity 102 in the hollow tube 101, cavity 102 cavity wall is equipped with the wire casing 103 that corresponds with sand grip 202, and the matching through sand grip 202 and wire casing 103 makes the combination of movable rod 1 and dead lever 2 inseparabler in the concrete implementation, and the sand grip 202 of peripheral hardware can improve the crushing resistance of pull rod solid tube 201 simultaneously.
In order to further improve the pressure resistance of the pull rod, the surface of the movable rod 1 is provided with a convex rib 7 to realize a strengthening effect. The convex rib 7 is spirally wound on the outer wall of the movable rod 1.
In the actual operation in-process, when case and bag pull-up removes, movable rod 1 is from the tensile back in dead lever 2, and the department of meeting of the two only has 1 terminal positioning mechanism of movable rod to connect, and relatively weak, movable rod 1 rocks easily, for this 1 terminal outer wall cover of movable rod establishes reinforcement seat 4, reinforcement seat 4 includes the bottom plate that keeps level with 1 terminal of movable rod, installs on the bottom plate and with the fixed a plurality of groups floor that link to each other of movable rod 1 outer wall.
In order to avoid the influence of the reinforcing seat 4 on the smooth movement of the movable rod 1 with the reinforcing seat 4 when the movable rod 1 moves, a sleeve 6 is arranged outside the fixed rod 2, a space for the movable rod 1 to move up and down is reserved between the sleeve 6 and the fixed rod 2, the outer edge of the reinforcing seat 4 abuts against the inner wall of the sleeve 6, and the top end of the sleeve 6 extends upwards relative to the fixed rod 2. The sleeve 6 can indirectly make the joint of the movable rod 1 and the fixed rod 2 more stable while protecting the fixed rod 2.
The hollow pipe 101 and the solid pipe 201 are square pipes, the edges and corners form circular arcs, and the bending-resistant section interfacial coefficient of the square pipes is larger than that of the round pipes.
The cross section of convex strip 202 is the outer wide inner narrow trapezium structure, and wire casing 103 is the cell body that corresponds with convex strip 202 for the difficult not hard up more stably of combination of wire casing 103 and convex strip 202.
In specific implementation, the device further comprises a positioning mechanism of the movable rod 1 and the fixed rod 2, which is used for fixing the movable rod and the fixed rod when the movable rod and the fixed rod are completely stretched, and the conventional design is adopted, and details are not repeated.
The foregoing merely illustrates preferred embodiments of the present invention, which are described in considerable detail and detail, but are not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several changes, modifications and substitutions can be made, which are all within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
