Abstract
The utility model relates to an item placing tool, in particular to a travel luggage. The technical scheme provided by the utility model is that the travel luggage comprises a luggage body, a retractable pull rod arranged on the luggage body, and rollers arranged on the luggage body, wherein the pull rod comprises an inner tube and an outer tube which is inserted inside the inner tube and can perform reciprocating sliding movement in the axial direction of the inner tube; the inner tube is a hollow metal tube body; the outer tube is a hollow plastic tube body; a plurality of positioning bulges are arranged on the inner wall of the outer tube; placing cavities are formed among the positioning bulges; a metal contact piece which is in contact with each positioning bulge is arranged in each placing cavity; an elastic contact piece is arranged between the metal contact piece and the outer tube inner wall. Through the adoption of the technical scheme, the travel luggage of which the pull rod stress strength is increased and the structure is simple is provided.
Description
Technical field
The utility model relates to a kind of article place tool, particularly a kind of luggage.
Background technology
Case and bag are a kind of people casings for placing articles in the time going out, its by casing, be located at the telescopic lever on casing and the roller be located on casing forms, user can pull pull bar, and casing is slided on the ground by roller.Traditional pull bar is all plastic material and is made, if as overweight in the article in casing, user's use pull bar is repeatedly implemented easily to cause pull bar distortion or damage while towing to casing, and production cost is high to adopt metal material to make pull bar, and can make the weight of case and bag increase.
Summary of the invention
The deficiency existing for prior art, the utility model provides a kind of pull bar that increases to be subject to force intensity, luggage simple in structure.
For achieving the above object, the utility model provides following technical scheme: a kind of luggage, include casing, be located at telescopic pull bar and roller on casing, it is characterized in that: described pull bar includes inner tube and is plugged in also can be along the outer tube of inner tube axial reciprocating slippage in inner tube, described inner tube is metal hollow body, outer tube is the plastic tube body of hollow, the inwall of outer tube is provided with some positioning convex, between positioning convex, form and place cavity, in placement cavity, be provided with the metal conflict part of conflicting with positioning convex, between metal conflict part and the inwall of outer tube, be provided with elasticity conflict part.
Adopt technique scheme, inner tube is in casing, it is metal hollow body, not only do not have influence on the overall weight of case and bag, and bearing capacity is strong, damage can not deform in the time carrying out case and bag, outer tube is the body outside case and bag while carrying out case and bag, its bearing strength is greater than inner tube, in order to make it have enough bearing strengths, can not affect production cost and increase overall weight simultaneously yet, positioning convex and metal conflict part are set within the outer tube, metallic positioning is implemented to compress to positioning convex, the force intensity that is subject to of outer tube is increased, separately, the setting of elasticity conflict part can further increase the force intensity that is subject to of outer tube, arrange so not only simple in structure, increase and be subject to force intensity, can effectively prevent that pull bar from deforming and damaging in the time carrying out casing.
The utility model is further set to: the inwall of outer tube is provided with four positioning convex, described metal conflict part is the metal tube being arranged between positioning convex, the conflict end points place of metal tube and positioning convex is provided with the conflict projection that cross section is " V " font, described elasticity conflict part includes one end and metal tube is conflicted, the spring that the other end and outer tube wall are conflicted.
Adopt technique scheme, arrange so simple in structure, processing and install more for convenience.
The utility model is further set to: outer axial tube offers some mounting grooves on the end face of a side, is inserted with respectively reinforcement in mounting groove.
Adopt technique scheme, the further force intensity that is subject to of having strengthened outer tube is set like this, make the outer further protection that is in control.
Below in conjunction with accompanying drawing, the utility model is further described.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A generalized section of Fig. 1.
Detailed description of the invention
As Fig. 1, a kind of luggage shown in Fig. 2, include casing 1, be located at telescopic pull bar 2 and roller 3 on casing 1, pull bar 2 includes inner tube 21 and is plugged in also can be along the outer tube 22 of inner tube 21 axial reciprocating slippages in inner tube 21, inner tube 21 is metal hollow body, the plastic tube body that outer tube 22 is hollow, the inwall of outer tube 22 is provided with some positioning convex 23, between positioning convex 23, form and place cavity 24, place in cavity 24 and be provided with the metal conflict part 25 of conflicting with positioning convex 23, between metal conflict part 25 and the inwall of outer tube 22, be provided with elasticity conflict part 26.In such scheme, inner tube 21 is in casing 1, it is metal hollow body, not only do not have influence on the overall weight of case and bag, and bearing capacity is strong, damage can not deform in the time carrying out case and bag, outer tube 22 is the body outside case and bag while carrying out case and bag, its bearing strength is greater than inner tube 21, in order to make it have enough bearing strengths, can not affect production cost and increase overall weight simultaneously yet, at interior positioning convex 23 and the metal conflict part 25 of arranging of outer tube 22, metallic positioning 25 is implemented to compress to positioning convex 23, the force intensity that is subject to of outer tube 22 is increased, separately, the setting of elasticity conflict part 26 can further increase the force intensity that is subject to of outer tube 22, arrange so not only simple in structure, increase and be subject to force intensity, can effectively prevent that pull bar 2 from deforming and damaging in the time carrying out casing 1.
In the utility model embodiment, the inwall of outer tube 22 is provided with four positioning convex 23, metal conflict part 25 is for being arranged in the metal tube between positioning convex 23, the conflict end points place of metal tube and positioning convex 23 is provided with the conflict projection 251 that cross section is " V " font, elasticity conflict part 26 includes one end and metal tube is conflicted, the spring that the other end and outer tube 22 inwalls are conflicted.Certainly, for make that spring can be stable in outer tube 22, can on the inwall of outer tube 22 and metal tube, be provided for respectively the spring base of mounting spring.
In order to make outer tube 22 be subject to the further reinforcement of force intensity, outer tube 22 is further protected, on the end face of the axial side of outer tube 22, offer some mounting grooves 221, the interior reinforcement 27 that is inserted with respectively of mounting groove 221.
