Description
Technical field
The utility model is related to luggage technical field, more particularly to a kind of trolley case.
Background technology
Trolley case refers to the luggage case with pull rod and idler wheel.Because its is easy to use, carrying clothing etc. becomes travelling, go out and
It is widely used.Meanwhile trolley case is divided into single tube pull rod and two-tube pulling rod, the pipe of pull rod is also also because chest puts a pull rod
It there are square tube and pipe, during facilitating walking in tow, reduces the heavy burdens significantly.Trolley case portable can also drag, we
The wheel of trolley case usually used is all located at chest bottom substantially, and modern has devised the pull rod of a neomorph
Chest has been designed to the moulding of cylinder by case, and then entire outsourcing is on the outside of chest for wheel, and such roller designs so that this drawing
Rod box can preferably adapt to different landform, and such as directly hauling chest can light stair activity.
Such as the patent that notification number is CN206150727U, a kind of external pull rod trolley case is disclosed, including trolley case
Ontology and pull rod, pull rod include main tie and telescopic rod, telescopic rod be equipped with handle, trolley case ontology back both sides and
Back upper end has recess, and main tie is mounted on the indent of the back both sides, when telescoping tube is retracted the main tie,
Handle is located at the indent of the back upper end.
The corner of the main tie setting babinet of above-mentioned trolley case, so main tie is highly prone to from external multi-angle side
To shock, and existing main tie and telescopic rod are made of relatively thin aluminium-alloy pipe mostly, so the main drawing of corner
The telescopic rod of bar and retraction main tie is highly prone to hit and is hit deformation even directly damage.

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
As shown in Figure 1, a kind of trolley case, including babinet 1, four rolling is mounted on the lower end quadrangle of babinet 1 respectively
7, in order to improve flexibility, using universal wheel as idler wheel 7.Handle 21 is fitted on the upper end of babinet 1 and side wall with side
Just lift babinet 1.
With reference to shown in Fig. 1 and Fig. 3, the whole groove 8 in "U" shaped is provided in the centre position at the back side of babinet 1, it is recessed
" U " font that slot 8 is formed is opening up, and the upper end position at 1 back side of babinet is provided with recess 9, recess 9 just with it is recessed
Slot 8 connects.
Pull rod 2 for dragging babinet 1 divides 4 two parts of telescopic rod to stretch for main tie 3 and in main tie 3, is stretching
Contracting bar 4 there are one handle 5, is provided with telescopic adjustment button 6 backwards to the connection of one end of main tie 3 on handle 5, main tie 3 is whole
In with the matched U-shaped of 8 global shape of groove, and the section of main tie 3 and telescopic rod 4 be all ellipse.Main tie 3 is embedded
In groove 8, and handle 5 is located in recess 9 when telescopic rod 4 is locked in main tie 3.
With reference to shown in Fig. 3 and Fig. 4, elastic bumps 10 are provided on the cell wall in groove 8, when main tie 3 is embedded in groove 8
When interior, elastic bumps 10 are compressed before this, and main tie 3 completely into after in groove 8, due to the elastic force of itself make by elastic bumps 10
With and gradually restore to be pushed against on main tie 3, by the frictional force between elastic bumps 10 and main tie 3 so that main tie 3 exists
It will not easily be dropped out after in embedded groove 8.When being installed to main tie 3, directly 3 face groove 8 of main tie is pressed
Enter in groove 8, so that main tie 3 is easy for assemble or unload.
Also, the upper end cell wall of that a part of groove 8 in 1 back side lower end of babinet is set as and 3 shape phase of main tie
The concave arc shape matched.After main tie 3 is embedded in groove 8, due to the elastic reaction of elastic bumps 10, main tie 3 is because by elasticity
Protrusion 10 effect and be bonded on the cell wall for being pushed against concave arc shape, the cell wall of concave arc shape, which can block main tie 3, prevents main tie 3
Front is taken out out of groove 8；Meanwhile when dragging babinet 1, hold on handle 5, main drawing is then transmitted to by telescopic rod 4
It remaking and is used on babinet 1 on bar 3, during 3 tension of main tie, a part for main tie 3 is just fitted on the cell wall of concave arc shape, from
And main tie 3 can be enable to bear the pulling force of bigger and be unlikely to deform.
In order to main tie 3 be embedded in groove 8 after facilitate taking-ups, so the straight bar part both sides of main tie 3 be provided with
The crescent 11 that groove 8 connects, the thumb of human hand and four fingers can be respectively protruding into the crescent 11 of the straight-bar both sides of main tie 3
It is interior to pinch main tie 3, then control 3 elasticity of compression protrusion 10 of main tie, then main tie is exited backwards to the back side forward direction of babinet 1
3。
Sliding slot 12 is additionally provided on the cell wall of groove 8, slidably connects backplate 13 in sliding slot 12, backplate 13 install into
After in sliding slot 12, backplate 13 covers the straight bar part of the main tie 3 in groove 8.Since telescopic rod 4 is in retraction main tie 3
When interior, telescopic rod 4 is located in the straight bar part of main tie 3, so influencing whether telescopic rod 4 in 3 stress deformation of main tie
It is flexible, and the other parts of main tie 3 will not then impact the flexible of telescopic rod 4, so setting backplate 13 covers main drawing
The straight bar part of bar 3 is protected, while backplate 13 can also resist main tie 3 to prevent 3 stress of main tie from being taken off out of groove 8
From.
Caulking groove 14 is also equipped in crescent 11, sealing plate 15 is embedded in caulking groove 14, sealing plate 15 can be with retraction caulking groove 14
It is interior, it can also be stretched out out of caulking groove 14 to cover crescent 11, so as to which sundries and dirt be avoided to enter in crescent 11.
With reference to shown in Fig. 1, Fig. 2 and Fig. 3, sealing plate 15 moves after crescent 11 is covered in order to prevent, in sealing plate 15 backwards
11 one side of crescent is provided with clamping stick 16, and is rotatably connected on the clamping stick 16 of the straight bar part side of main tie 3
Card 17, one end of this clamping stick 16 is provided with bayonet 18 with card 17 and inlay card is another in the straight bar part of main tie 3
In the annular groove 19 on clamping stick 16 on the sealing plate 15 of side.So that two side seal board 15 of straight-bar of main tie 3 is covering the moon
It will not be away from each other after alveolus 11 and in retraction caulking groove 14.
In addition, one layer of rubber pad 20 is provided in one side of the card 17 towards backplate 13, the rubber after the card of card 17 is good
Rubber cushion 20 is pushed against on backplate 13, is acted on by the frictional force between rubber pad 20 and backplate 13 so that backplate 13 is being installed to
Sliding slot 12（It is visible in Fig. 4）It will not easily be slided after interior, so as to enable the main drawing of covering protection that backplate 13 is stablized
The straight bar part of bar 3.
This specific embodiment is only explanation to the utility model, is not the limitation to the utility model, ability
Field technique personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but
As long as it is all protected in the right of the utility model by Patent Law.
