Description

Technical Field

[0001] The utility model relates to the technical field of extended houses, in particular to a multi-purpose manual extended house. Background Art

[0002] A mobile extended house refers to a mobile building that can move and expand space. It is widely used in emergency events, such as: temporary storage places after disasters, command posts during disasters, etc. At present, with the rapid development of mobile extended house technology, such mobile buildings are also used in more and more places, such as: outdoor camping, scenic area vacations, etc. The design direction of mobile extended houses generally focuses on facilitating transportation.

[0003] The current mobile extended house technology is very mature in the expansion direction and can fully meet the need for expanded space. However, when designing the current mobile extended houses, little consideration is given to their own mobility. No corresponding moving structure and supporting structure are set for the mobile extended houses. This results in the situation that although the mobile extended houses can be transported to the designated location by means of freight vehicles, trailers and other transportation tools, during installation, the position of the extended house needs to be moved by lifting it with multiple people, which has the problems of inconvenience in short-distance movement of the extended house and inability to fix the extended house after movement.

[0004] In the invention with the application number: CN201680069277.7 and the publication number: CN109312561B, a movable two-way extended house is disclosed, including: a main body frame, an extended frame, a first driving mechanism, a floor member, a second driving mechanism. Although it can meet the need for expanded space, it does not set a corresponding moving structure and supporting structure for the extended house. Therefore, when in use, there are still the problems of inconvenience in short-distance movement of the extended house and inability to fix the extended house after movement.

[0054] During installation, first manually move the present utility model to the designated position, and then manually drive the rotating handle 108 to drive the worm 106 to rotate. Thus, drive the worm gear 105 to rotate through the worm 106, and then drive the threaded sleeve 104 to rotate through the worm gear 105, so that the threaded rod 103 extends until the support plate 107 contacts the ground to fix the present utility model at the designated position. Then install the support cross bar 205, and adjust the support foot member 213 so that the support pad 217 contacts the ground. Then flip the top extension plate 202 to be parallel to the support cross bar 205. Then install the support vertical rod 206 so that the support vertical rod 206 supports the top extension plate 202. Then flip the bottom extension plate 201 to be clamped with the card slot 211. Then flip the first side extension plate 200 to be perpendicular to the top extension plate 202 and the bottom extension plate 201, and make the first side extension plate 200 contact the support vertical rod 206. Then flip a pair of second side extension plates 203 to be parallel to the support cross bar 205 respectively, thus completing the unfolding of the present utility model.

[0055] The present utility model not only solves the problems that the current mobile extension house is not convenient for short-distance movement and cannot be fixed after movement, but also solves the problem of high overseas transportation cost of containers. Through the folding method in the above embodiments, the products actually produced by us can just fit three in a 20-foot standard sea container or six in a 40-foot standard sea container, greatly saving the transportation cost.

[0056] The working principle of the present utility model:

[0057] When the present utility model is in use, it can drive the rotating handle 108 manually to drive the worm 106 to rotate. Thus, drive the worm gear 105 to rotate through the worm 106, and then drive the threaded sleeve 104 to rotate through the worm gear 105, so that the threaded rod 103 extends or retracts, thereby realizing the adjustment of the height of the support plate 107, so as to facilitate the contact between the support plate 107 and the ground or the contact between the universal wheels 113 and the ground. During transportation and installation, it is necessary to extend the support plate 107 to the bottom of the universal wheels 113, so that the multi-purpose manual extension house described in the present utility model can be supported and fixed by the support plate 107 to prevent it from moving through the universal wheels 113. When short-distance movement is required, it is necessary to retract the support plate 107 above the universal wheels 113, make the universal wheels 113 contact the ground, and then push manually, so that the multi-purpose manual extension house described in the present utility model can be moved through the universal wheels 113 at the bottom. Compared with the traditional mobile expansion house, the present utility model realizes the movement and fixation of the mobile expansion house by setting the universal wheels 113 and the corresponding lifting assembly 101.

[0058] The above-described embodiments merely represent the specific implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
