[0031] An assembled fixed structure and municipal building enclosure thereof, such as Figure 1 As shown, including:

[0032] The mutually detachable connecting female heads 10 form a columnar structure with a circular cavity;

[0033] The connecting male head 11 is a rod structure that is detachably connected to the connecting female head 10. The bottom of the connecting male head 11 is fixedly connected with an insert rod 12, which is plugged into the circular cavity of the connecting female head 10. Specifically, the connecting female head 10 includes a rectangular plate and a round tube portion. The round tube is fixedly connected to one side of the rectangular plate. The cylindrical insert rod 12 is plugged into the round tube of the connecting female head 10 to achieve the connection between two adjacent enclosure bodies. It has the characteristic of being easy to assemble. Multiple enclosure bodies are connected end to end to form a protective barrier, which is convenient for construction. The enclosure body includes a rectangular frame and a number of columns fixedly installed in the rectangular frame, which will not be elaborated here.

[0034] like Figure 2 , Figure 3 and Figure 6As shown, the limiting structure is arranged on the wall surface of the plug rod 12 for locking and limiting the connection male head 11. The limiting structure includes a limiting block 20, a pressure block 21, a thrust protrusion 22 and a screw 23. The end of the plug rod 12 is elastically connected to the two limiting blocks 20. The limiting block 20 can resist the bottom end of the connection female head 10 to limit the plug rod 12 from being separated from the circular cavity of the connection female head 10. The plug rod 12 forms a cylindrical structure. Two horizontal notches are opened on the bottom surface of the plug rod 12. Two limiting blocks 20 are arranged at the lower end of the plug rod 12. The limit block 20 slides in the corresponding horizontal slot, and a first elastic member is provided in the horizontal slot to push the limit block 20 to slide. The limit block 20 forms a rod structure with an L-shaped transverse cross section. The bottom surface of the limit block 20 is chamfered to form a slope. The vertical part of the limit block 20 is adapted to the horizontal slot and slidably connected. The first elastic member includes a spring but is not limited to a spring. The elastic member is arranged on one side of the limit block 20. The two limit blocks 20 slide in the opposite direction. In this solution, two reverse blocks are arranged at the bottom of the insertion rod 12. When the insertion rod 12 is inserted into the round tube of the female connector 10, the horizontal component force generated by the squeezing force of the female connector 10 pushes the limit block 20 to slide through the cross section at the bottom of the limit block 20. The limit block 20 slides in the horizontal slot and squeezes the first elastic member. The first elastic member is a spring, and the two ends of the spring are respectively fixedly connected to the limit block 20 and the inner wall of the insertion rod 12, so that the limit block 20 slides into the horizontal slot. When the insertion rod 12 passes through the round tube of the female connector 10, the limit block 20 is pushed into the horizontal slot. When the locking cam 12 is engaged, the limit blocks 20 are pushed away from each other by the spring, and the top surface of the limit blocks 20 contacts the bottom end of the round tube of the female connector 10, thereby locking and limiting the insertion rod 12. At the same time, the insertion rod 12 can rotate horizontally in the round tube of the female connector 10, which is easy to install and can rotate and adjust the angle between the enclosure bodies. The adjustable enclosure body can be adjusted according to the shape of the location to be protected, such as a circular pit or a rectangular pile foundation protection enclosure. It is flexible and convenient to use and has strong adaptability.

[0035] like Figure 5As shown, the pressing block 21 is elastically connected to the insertion rod 12, the thrust protrusion 22 is fixedly connected to the pressing block 21, the thrust protrusion 22 can be engaged with the upper end surface of the connecting female head 10 to limit the rotation of the insertion rod 12, the screw 23 is threadedly connected to the connecting male head 11, the screw 23 can push the pressing block 21 to contact the upper end surface of the connecting female head 10, the limiting structure also includes a plurality of grooves 24 opened on the top of the connecting female head 10 for limiting the thrust protrusion 22, the thrust protrusion 22 can be inserted into the grooves 24 at different positions to lock the angle between the connecting male head 11 and the connecting female head 10, the pressing block 21 forms an annular plate structure, the insertion rod 12 passes through the central part of the pressing block 21, the pressing block 21 can slide radially along the insertion rod 12, and the pressing block 21 can be pressed. A second elastic member is provided on the top of the block 21, and the second elastic member includes a spring but is not limited to a spring. The second elastic member is sleeved on the wall of the insertion rod 12, and an elastically connected pressure block 21 is provided. The second elastic member takes a spring as an example. The spring pushes the pressure block 21 to contact the top of the connecting female head 10, and then the thrust protrusion 22 is inserted into the groove 24 at the corresponding position to achieve the position locking of the connecting male head 11. Due to the spherical thrust protrusion 22, when the connecting male head 11 is rotated, the connecting male head 11 will be subject to a certain resistance but will not be completely locked in position. At this time, the position of the connecting male head 11, that is, the angle between the two enclosure bodies, can be flexibly adjusted. There is a certain locking force and the convenience of adjusting the angle is taken into account.

[0036] like Figure 2 and Figure 5 The connecting male head 11 forms an L-shaped plate, and a threaded hole is provided on the horizontal part of the connecting male head 11. The screw rod 23 is adapted to the threaded hole, and the screw rod 23 is threadedly connected to the threaded hole. The lower end surface of the screw rod 23 can abut against the top of the pressing block 21 and push the pressing block 21 to slide. By setting the screw rod 23 and rotating the screw rod 23, the bottom end of the screw rod 23 abuts against the top of the pressing block 21. The squeezing force of the pressing block 21 given by the screw rod 23 makes the pressing block 21 fit tightly against the top surface of the connecting female head 10, and then the thrust protrusion 22 is stably located in the groove 24 at the corresponding position. At this time, since the pressing block 21 cannot slide up and down, the angle between the connecting male head 11 and the connecting female head 10 is in a completely locked state, and the angle adjustment and locking between the connecting male head 11 and the connecting female head 10 are stable and convenient.

[0037] like Figure 2As shown, the thrust protrusion 22 is integrally formed with the pressure block 21, and the thrust protrusion 22 is located at the bottom of the pressure block 21. The thrust protrusion 22 forms a hemispherical structure. The end face of the thrust protrusion 22 is connected to the pressure block 21, and the spherical surface of the thrust protrusion 22 faces the connecting female head 10. The groove 24 forms a circular hole adapted to the thrust protrusion 22. The top of the connecting female head 10 is provided with a plurality of identical grooves 24 in a ring array. By setting the hemispherical thrust protrusion 22, when the connecting male head 11 is rotated, the thrust of the spherical surface of the thrust protrusion 22 given by the connecting female head 10 causes the pressure block 21 to slide radially along the insertion rod 12 and squeeze the spring to deform. When the thrust protrusion 22 moves to face another groove 24, the thrust protrusion 22 falls into the groove 24 to realize the positioning of the connecting male head 11. The position can be adjusted and locked by simply rotating the connecting male head 11 without manual intervention.

[0038] A municipal building enclosure comprises an enclosure body, the side wall of the enclosure body is provided with all the above-mentioned assembling and fixing structures, a connecting female head 10 is fixedly mounted on one side of the enclosure body, a connecting male head 11 is fixedly mounted on the other wall of the enclosure body, and the connecting female head 10 and the connecting male head 11 are symmetrically arranged. By arranging the above-mentioned assembling and fixing structure, multiple enclosure bodies can be easily installed when spliced ​​for use, and the angles between the enclosure bodies can be adjusted separately, which can better adapt to the enclosure protection of irregular foundation pits during the construction of municipal engineering projects, and has strong adaptability and high adjustability.

[0039] The working principle of the utility model is as follows: the cylindrical insertion rod 12 is plugged into the round tube of the connecting female head 10 to realize the connection between the two adjacent enclosure bodies, and two counter-sliding limit blocks 20 are set at the bottom of the insertion rod 12. When the insertion rod 12 is inserted into the round tube of the connecting female head 10, the cross-section at the bottom of the limit block 20 is subjected to the horizontal component force generated by the extrusion thrust of the connecting female head 10 to push the limit block 20 to slide, and the limit block 20 slides in the horizontal groove and squeezes the first elastic member. The first elastic member is a spring as an example. The two ends of the spring are respectively fixedly connected to the limit block 20 and the inner wall of the insertion rod 12, and then the limit block 20 slides into the horizontal groove. When the insertion rod 12 passes through the round tube of the connecting female head 10, the limit blocks 20 move away from each other under the pushing action of the spring, and the top surface of the limit block 20 contacts the bottom end of the round tube of the connecting female head 10, so as to realize the locking limit of the insertion rod 12.

[0040] When the male connector 11 is rotated, the thrust of the spherical surface of the thrust protrusion 22 given by the female connector 10 causes the pressure block 21 to slide radially along the insertion rod 12 and squeeze the spring to deform. When the thrust protrusion 22 moves to face another groove 24, the thrust protrusion 22 falls into the groove 24 to achieve the positioning of the male connector 11, or the screw rod 23 is rotated, and the bottom end of the screw rod 23 contacts the top of the pressure block 21. The squeezing force given to the pressure block 21 by the screw rod 23 makes the pressure block 21 fit tightly to the top surface of the female connector 10, and then the thrust protrusion 22 is stably located in the groove 24 at the corresponding position. At this time, since the pressure block 21 cannot slide up and down, the angle between the male connector 11 and the female connector 10 is in a completely locked state.

[0041] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
