Detailed Description

For a better understanding of the technical solutions of the present invention, the following preferred embodiments of the present invention are described in conjunction with the specific examples, but it should be understood that the descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the patent claims of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The utility model will be further described with reference to the accompanying drawings and preferred embodiments.

Example 1

Referring to fig. 1, the vertical jack that top portion is extensible that this embodiment relates to includes jack main part 1, is equipped with on jack main part 1 and makes the jacking post 2 of perpendicular up-and-down motion, still includes highly inequality first extension post 3 and second extension post 4, the bottom of first extension post 3 and second extension post 4 all has spliced pole 5, the guiding hole 6 that supplies spliced pole 5 to insert is seted up at the top of jacking post 2.

Furthermore, the bottom of the connecting column 5 is provided with a pin hole 7, and the jack main body 1 is provided with a positioning pin 8 inserted into the pin hole 7.

In the embodiment, the first extension column 3 is arranged on the jacking column 2, and the upper connecting column 5 is inserted into the guide hole 6, so that the height extension of the jacking column 2 is realized; and the unused second extension column 4 is placed on the jack main body 1, and the positioning pin 8 on the jack main body 1 is inserted into the pin hole 7 of the connecting column 5 of the second extension column 4 to wait for switching use.

Example 2

Referring to fig. 1 and 2, in the extendable top upright jack according to the present embodiment, on the basis of embodiment 1, it is further configured that an elastic member (not marked in the drawings) is provided on the positioning pin 8; the elastic piece is including establishing connection piece 9 at the top of locating pin 8, and the both sides of connection piece 9 extend respectively have the upper end to be close to locating pin 8, keep away from the shell fragment 10 of locating pin 8 downwards gradually.

Furthermore, the end face of the elastic sheet 10 facing the positioning pin 8 is provided with an inner bending portion 11, and the side face of the positioning pin 8 is provided with an annular groove 12 for embedding the inner bending portion 11.

Further, the elastic piece is made of brass material.

In this embodiment, through add the elastic component on locating pin 8 for first extension post 3 and second extension post 4 can have the tight fit effect when realizing being connected with locating pin 8 respectively, avoid toppling over or overturning and make extension post (first extension post 3 or second extension post 4) drop from the locating pin 8 that is being connected because of vertical jack.

When the positioning pin 8 is inserted into the pin hole 7 together with the elastic piece, the hole wall of the pin hole 7 gradually extrudes the elastic piece 10 to deform the elastic piece, the inner bending part 11 is partially embedded into the annular groove 12, and the positioning pin 8 and the pin hole 7 are kept in tight fit; when the two are needed to be separated, the two can be separated by applying upward pulling force slightly.
