Description

Extended trolley

The invention relates to an extended type trolley, in particular to a telescopic rod group and a front and a rear seat and an extension platform, which can conveniently achieve the folding, positioning and lengthening of the length of the carrying platform, so that it can be more conveniently placed. An enlarged item that increases the load-bearing area and does not affect its overall structural strength.

According to the collapsible trolley on the market (as shown in the first figure), it is a schematic diagram of the telescopic control structure of the carrying platform 1, and the front and rear seats 10, 11 and the telescopic rod group 12 are respectively fixed at the front and the rear. In combination, when the item to be carried is required to be carried, the carrying platform 1 can be elongated for placing the object, and only the one side of the telescopic rod set 12 is fixed on the front and rear seats 10 and 11, and it is impossible to meet the large items. The use of trolleys or multiple items can not be transported at one time because the load-bearing area is too small, and the handling time is increased, so there is still room for improvement in use.

Accordingly, the inventors of the present invention have developed and improved the lack of the above-mentioned conventionally accommodating carrier, so that the utility and assembly convenience can be achieved.

The main object of the present invention is to provide an elongated trolley that can be easily folded and lengthened.

The main feature of the present invention is: a front seat, the front seat is arranged with a plurality of telescopic inner and outer tubes, the front seat is provided with a pivoting seat of the handle on the front side, and a joint seat of the casters is arranged on the bottom surface; the extension platform is arranged at the rear of the front seat. The extension platform is provided with a telescopic inner and outer tube which is arranged and penetrates the extension platform, and is connected with the telescopic outer and inner tubes of the front and rear seats, and is provided with a combination of casters on the bottom surface; The rear seat is arranged with a plurality of telescopic inner and outer tubes arranged in the rear seat, and is inserted into the telescopic outer and inner tubes of the extension platform. The rear seat is provided with a pivotal seat of the handle on the front side and casters on the bottom surface. The pressing rod is pressed and fixed on the telescopic inner and outer rods of the front and rear seats respectively; the positioning rods are respectively fixed on the inner and outer tubes of the telescopic expansion, and the front and rear seats can be fixed and fixed.

The preferred embodiments of the present invention, in conjunction with the drawings, are as follows:

First, as shown in the second embodiment of the present invention, the trolley platform 2 is mainly provided with a front seat 20, an extension platform 21, a rear seat 22, a plurality of pressure bars 23 and a plurality of positioning rods 24, wherein The telescopic inner tubes 200 and 220 are arranged on the outer side of the front and rear seats 20 and 22, and the plurality of telescopic outer tubes 201 and 221 are arranged in the center, and the fixing holes 2010 and 2210 are arranged at the ends of the telescopic outer tubes 201 and 221, and the front and rear seats are arranged. 20, 22 is provided with a pivotal seat 202, 222 of the handle A on the front side, and a joint 203, 223 of the caster B is arranged on the bottom surface, and positioning cards 204, 224 are arranged at appropriate positions inside the front and rear seats 20, 22, Further, the telescopic inner tubes 200 and 220 of the front and rear seats 20 and 22 and the telescopic outer tubes 201 and 221 are positioned with a pressing rod 23; the extending platform 21 is disposed between the front and rear seats 20 and 22, and the extending platform 21 A telescopic inner tube 210 and a telescopic outer tube 211 are inserted therein, wherein a telescopic inner tube 210 is arranged in the center, and both sides are provided with a telescopic outer surface. a tube 211, and a fixing hole 2110 is disposed at two ends of the telescopic outer tube 211, and a coupling seat 212 of the caster B is disposed at the bottom of the extension base 21; the plurality of positioning rods 24 are fixed to the front and rear seats 20, 22 and the extension platform 21 telescopic inner and outer tubes 200, 220, 210, 201, 221 and 211, wherein two positioning rods 24 are provided with positioning cards 240; screwing elements N.

When combining, the telescopic inner and outer tubes 210 and 211 of the extension table 21 are respectively inserted into the telescopic outer and inner tubes 201 and 200 of the front seat 20, and then the positioning rod 24 and the end of the telescopic outer tube 201 of the front seat 20 are respectively respectively. The fixing hole 2010 takes the screwing element N to be screwed, and the other positioning rod 24 is screwed with the fixing hole 2110 at the end of the telescopic outer tube 211 of the extension table 21, and then the rear seat 22 is telescoped inside and outside. The tubes 220 and 221 are respectively inserted into the telescopic outer and inner tubes 211 and 210 of the extension table 21, and then the positioning rods 24 are screwed to the fixing holes 2110 of the end of the tube 211 outside the extension table 21 by the screwing members N, respectively. The other positioning rod 24 is screwed to the fixing hole 2210 at the end of the telescopic outer tube 221 of the rear seat 22 to screw the component N, so that the carrying platform can be easily extended and folded, and then the front seat 20 The casters 203, 212 and 223 of the casters of the extension table 21 and the rear seat 22 are fixed to the casters B, and are provided in the front and rear seats 20 The pivot mount 22 in conjunction with the handle 202, 222 A, i.e., the completion of a trolley lengthened.

In use, the positioning cards 204, 224 on the front and rear seats 20, 22 are firstly disengaged from the positioning rod 24, and the front and rear seats 20, 22 are pulled outward from the extension table 21 to be positioned, so that the positioning rod 24 is The positioning card 240 is engaged with the other positioning rod 24 (as shown in FIG. 6), so that an extended trolley can be easily completed, and the extension table 21 is provided with the caster B, so it is not lengthened. When the bearing strength is reduced, and the positioning card 240 on the positioning rod 24 is only required to be disengaged from the positioning rod 24, the front and rear seats 20 and 22 can be easily folded, so that the positioning rods 24 are respectively engaged. On the positioning cards 204, 224 on the front and rear seats 20, 22, so that the front and rear seats 20, 22 can be stably moved (as shown in Fig. 5).

It can be seen from the above description that the present invention has the following advantages: 1. The extension table 21 of the present invention can not only extend the bearing length and area of the trolley carrier 2, but also does not reduce the bearing strength of the carrier 2 due to the extension table 21 The caster B is also fixed, so it can reinforce the strength and facilitate the pusher. 2. The trolley of the present invention can also be folded to the length of the normal trolley, and because the caster B is also screwed on the central extension 21, the heavier object can be loaded without deformation.

However, the above is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the equivalent changes or modifications made by the scope of the present invention and the contents of the description of the invention should still be It is within the scope of the patent of the present invention.
