Hence, the pulling post can project outward as well as withdraw backward automatically. The utility model has the advantages of simple structure, convenience for use and automation. Meanwhile, the build-in battery inside the case body can be applied as a power supply for other electric equipments such as mobile phones, portable computers and password locks of luggage to meet users temporary needs for power supply, which provides great convenience for users going out.
Description
Technical field:
The utility model relates to technical field of living goods, refers in particular to a kind of trailer-type luggage case improvement of the luggage that is easy to carry.
Background technology:
Luggage case can be described as the common tool that people go out to carry and deposit article, and lighter in order to carry, the generally all subsidiary trailer configuration of existing luggage case.Trailer configuration includes pull bar and roller, and roller is installed on the bottom of luggage case, just need not during use luggage case is mentioned, and can directly drag luggage case by roller on ground, to alleviate the carry luggage burden of case of user; Pull bar is set is for the ease of dragging the usefulness of luggage case, it is the telescopic body of rod, and it is quite convenient to use, thereby also is subjected to people's favor deeply.Yet the pull bar of current trailer configuration is manually flexible, and pulling out and withdrawing all needs staff to give the application of force, still has inconvenience when reality is used, in case can't pull out or withdraw during application of force deficiency, and hand is too bothersome.Simultaneously, existing trailer-type luggage case function singleness the effect of depositing, carrying except having, does not have other attach feature again, as power supply etc. is provided, so that the usefulness of the interim power supply of going out.
Summary of the invention:
The purpose of this utility model is to overcome the defective of prior art, and a kind of trailer-type luggage case improvement of pull bar automatically retractable is provided, and it is simple in structure, and is easy to use, also can provide interim power supply.
For achieving the above object, pull bar of the present utility model is an electric expansion body, its inner screw rod that is threaded, but screw rod by the electrical motor driven of rotating, and electro-motor is by the power supply power supply that is arranged in the casing.
Power supply in the described casing is also drawn some power lines that electrically connect other consumer.
The utility model is the electric expansion body at pull bar, can stretch out automatically and withdraw, and is simple in structure, easy to use, reaches automation efficacy; The utility model also has the effect to the external equipment power supply simultaneously, promptly give other consumer power supply, as the coded lock of mobile phone, laptop computer and luggage case etc., to solve the problem of user's temporary electricity difficulty by its built-in power supply, provide greatly convenient to the user, conveniently go out.
Description of drawings:
Accompanying drawing 1 is a combining structure schematic diagram of the present utility model;
Accompanying drawing 2 is the power syndeton schematic diagram of the pull bar of the utility model.
The specific embodiment:
See shown in the accompanying drawing 1～2 that the utility model comprises casing 1 and pull bar 2, pull bar 2 activities are mounted in the casing 1, and have Handheld Division 21 to expose casing 1.Wherein pull bar 2 is an electric expansion body, the inner of pull bar 2 is provided with internal thread hole, and by the internal thread hole screw rod 3 that is threaded, screw rod 3 is driven by electro-motor 4 by corresponding gear drive, electro-motor 4 can be realized rotating, it is by power supply 5 power supplies that are arranged in the casing 1, and power supply 5 is also drawn some power lines 51 that electrically connect other consumer.
Need drag when using, press corresponding power switch, connect the power supply of electro-motor 4, electro-motor 4 rotates and gear drive drives screw rod 3 rotations, thereby utilize the external screw thread of screw rod 3 and the screw-internal thread fit of pull bar 2 lower ends to come pushing drawing rod 2 to stretch out outward, so that the user grips the Handheld Division 21 pulling luggage cases of pull bar 2 outer ends, cooperate the roller 6 of casing 1 lower end can drag casing 1 and move ahead on ground, reach and carry purpose.
When withdrawing pull bar 2, press reversal switch, make electro-motor 4 do the rotation that turns to when pull bar 2 stretches out, equally by 3 revolutions of electro-motor 4 drive screws, screw rod 3 revolution and matching relationship pulling pull bar 2 by internal and external screw thread reclaims, realize the withdrawal of automation control pull bar 2, it is quite convenient to use.
Simultaneously, the utility model can also be given other consumer power supply by its built-in power supply 5, electrically connect the coded lock of mobile phone, laptop computer and luggage case etc. by the power supply 5 outer power lines of drawing 51, to solve the problem of user's temporary electricity difficulty, provide greatly convenient to the user, conveniently go out.
