Description

Technical Field

[0001] The utility model relates to the technical field of assembled mobile toilets, and more specifically, to a combined connecting piece for an assembled mobile toilet. Background Technique

[0002] A mobile public toilet refers to a public toilet building that can be repeatedly and conveniently moved as a whole to the location where it needs to be set up to provide toilet services for the public. In order to move the public toilet, the public toilet is built with an assembled structure. When moving, it can be disassembled and reassembled again after moving to the predetermined location. Among them, the assembled public toilet needs to use connecting pieces to connect the plates.

[0003] After retrieval, the utility model patent with the publication number of CN219137978U discloses a combined connecting piece for an assembled public toilet, including a support frame. There are two locking screws on the outer wall of the support frame, and two positioning tubes are fixedly installed on the inner wall of the support frame. The back surface of the support frame is connected to a second support frame. There are two second locking screws on the second support frame, and two second positioning tubes are fixedly installed on the inner wall of the second support frame. This application can avoid consuming a large number of connecting pieces during the assembly process.

[0004] However, the above patent still has the following deficiencies: it can only connect the corners of two butting plates, and it is not convenient to stably connect the middle parts of two combined plates, and there are easily gaps and water seepage phenomena; in addition, the material thickness at the bottom of the positioning tube causes gaps between the bottom plate or top plate and the vertical plates after installation, affecting the sealing performance after assembly. Therefore, we propose a combined connecting piece for an assembled mobile toilet. Content of the Utility Model

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a combined connecting piece for an assembled mobile toilet.

[0006] To solve the above problems, the utility model adopts the following technical solutions:

[0007] A combined connector for a prefabricated mobile toilet, comprising an L-shaped column. Installation grooves are respectively arranged at both ends of the L-shaped column. Two groups of first installation holes are formed in the inner wall of the L-shaped column. One group of first threaded holes is respectively formed in the inner walls of the two installation grooves. Second threaded holes are formed at both the bottom end and the top end of the L-shaped column. A top and bottom plate fixing mechanism is arranged on the L-shaped column. Side plates are respectively sleeved in the inner cavities of the installation grooves. A plurality of second installation holes are respectively formed at both ends of the side plates. First bolts are sleeved in the inner cavities of the first installation holes. The end parts of the first bolts respectively penetrate through the second installation holes and are threadedly installed into the inner cavities of the first threaded holes. A top plate is arranged at the top of the L-shaped column, and a bottom plate is arranged at the bottom of the L-shaped column. A plurality of stepped holes are formed on the top surface of the top plate and the bottom surface of the bottom plate. Second bolts are sleeved in the inner cavities of the stepped holes. The end parts of the second bolts are threadedly installed into the inner cavities of the second threaded holes.

[0008] As a preferred solution of the present invention, the top and bottom plate fixing mechanism includes L-shaped connecting frames fixedly connected to the top end and the bottom end of the L-shaped column. A plurality of third installation holes are respectively formed in the two L-shaped connecting frames. Self-tapping screws are sleeved in the inner cavities of the third installation holes. The end parts of the self-tapping screws are threadedly installed into the interior of the top plate or the bottom plate.

[0009] As a preferred solution of the present invention, two rubber sealing strips are respectively fixedly connected to both ends of the L-shaped column. The inner side surfaces of the rubber sealing strips are attached to the outer side surfaces of the side plates.

[0010] As a preferred solution of the present invention, the inner wall of the installation groove is attached to the side surface of the side plate.
