[0011] Beneficial effects:
[0012] 1. In the utility model, the flexibility of the protective shed can be improved by setting up a fixed shed, a mobile shed and a connecting mechanism. When it is necessary to occupy the construction road, the mobile shed can be moved away by simply unlocking the connecting mechanism, which greatly reduces the time for disassembling the protective shed in the prior art and improves construction efficiency.
[0013] 2. In the present invention, by setting the cross-sectional size of the mobile shed equal to the cross-sectional size of the fixed shed, the assembly of the mobile shed and the fixed shed can be facilitated, while avoiding gaps at the joints that affect the protective effect and improving the aesthetic effect.
[0014] 3. In the present invention, the provision of multiple casters can facilitate the movement of the mobile shed, and there is no need to provide tracks on the ground, which can better protect the ground.
[0015] 4. In the utility model, by setting the square sleeve, square sleeve rod, pin shaft and elastic component, the cooperation of the square sleeve and the square sleeve rod can be used to facilitate the positioning of the connection between the mobile shed and the fixed shed. Combined with the cooperation of the pin shaft and the through hole, the two can be locked conveniently to improve the installation efficiency; by setting the telescopic rod and the spring, the elastic force of the spring can be used to realize the automatic locking of the pin shaft and the through hole, and at the same time, it can ensure that the pin shaft and the through hole are firmly matched and will not be freely separated.
[0016] 5. In the utility model, the square sleeve ring is provided to restrict the pin shaft in the mounting hole, thereby facilitating the connection between the square sleeve rod and the square sleeve tube. Specifically, before assembly, the square sleeve ring is first slid to the mounting hole, and the pin shaft is restricted in the mounting hole by compressing the telescopic rod and the spring, and then the mobile shed is pushed toward the fixed shed. When the square sleeve rod and the square sleeve tube are matched, it is only necessary to continue to move the mobile shed until the pin shaft is matched with the through hole to be fully installed. In this process, due to the action of the square sleeve ring and the square sleeve tube, the pin shaft will not slide out of the mounting hole before matching with the through hole, thereby avoiding its interference with the installation.
[0017] 6. In the utility model, the setting of the guide rod with a conical structure can facilitate the positioning during the splicing process of the mobile shed and the fixed shed, and further improve the installation efficiency. Specifically, when moving the mobile shed, the guide rod will cooperate with the square sleeve rod and the square sleeve tube before. Relative to the size of the square sleeve rod, the size of the top of the guide rod is much smaller than the size of the square sleeve rod. Therefore, it can be conveniently and quickly inserted into the square sleeve tube. Combined with the setting of the hinged end of the guide rod and the square sleeve rod, the matching angle can be appropriately adjusted. During splicing, the mobile shed can achieve effective cooperation with the fixed shed even if it is not coaxial or skewed. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In this embodiment, by setting the cross-sectional dimensions of the mobile shed 2 equal to the cross-sectional dimensions of the fixed shed 1, the assembly of the mobile shed 2 and the fixed shed 1 can be facilitated, while avoiding gaps at the joints that affect the protective effect and improving the aesthetic effect.
[0035] In the present invention, preferably, Figure 1 As shown, a plurality of casters 4 are provided at the bottom of the mobile shed 2 in contact with the ground, and the plurality of casters 4 are symmetrically arranged about the central axis of the mobile shed 2 .
[0036] In this embodiment, the multiple casters 4 are provided to facilitate the movement of the mobile shed 2, and there is no need to provide tracks on the ground, which can better protect the ground.
[0037] In the present invention, preferably, Figure 1 , Figure 2 and Figure 3As shown, the connecting mechanism 3 includes a square sleeve 31, a square sleeve rod 32, a pin 33 and an elastic component. The square sleeve 31 is fixedly installed on one side of the end of the fixed shed 1, and the square sleeve rod 32 is fixedly installed on one side of the end of the mobile shed 2 and is opposite to the square sleeve 31. A through hole 5 is provided on the square sleeve 31, wherein a plurality of through holes 5 can be provided along the length direction of the square sleeve 31 to facilitate the adjustment of the spacing between the mobile shed 2 and the fixed shed 1. A mounting hole 6 is provided on the square sleeve rod 32, and the pin 33 is slidably connected with the mounting hole 6 through the elastic component. When one end of the pin 33 away from the elastic component slides out of the mounting hole 6 under the action of the elastic component and cooperates with the through hole 5, the mobile shed 2 and the fixed shed 1 are relatively fixed; the elastic component includes a telescopic rod 7 and a spring 8, and the two ends of the telescopic rod 7 are respectively fixedly connected with the bottom of the mounting hole 6 and the end of the pin 33, and the spring 8 is sleeved outside the telescopic rod 7, and the two ends of the spring 8 are respectively fixedly connected with the bottom of the mounting hole 6 and the end of the pin 33.
[0038] In this embodiment, by setting the square sleeve 31, the square sleeve rod 32, the pin 33 and the elastic component, the square sleeve 31 and the square sleeve rod 32 can be used to conveniently position the connection between the mobile shed 2 and the fixed shed 1, and the pin 33 and the through hole 5 can be used to facilitate the locking of the two, thereby improving the installation efficiency; by setting the telescopic rod 7 and the spring 8, the elastic force of the spring 8 can be used to realize the automatic locking of the pin 33 and the through hole 5, while ensuring that the pin 33 and the through hole 5 are firmly matched and will not detach freely.
[0039] In the present invention, preferably, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the connecting mechanism 3 further includes a square ring 34 , which is slidably sleeved on the square sleeve rod 32 , and the outer ring size of the square ring 34 is larger than the inner ring size of the square sleeve 31 .
[0040] In this embodiment, by setting the square ring 34, the pin shaft 33 can be restricted in the mounting hole 6, thereby facilitating the connection between the square sleeve rod 32 and the square sleeve tube 31. Specifically, before assembly, the square ring 34 is first slid to the mounting hole 6, and the pin shaft 33 is restricted in the mounting hole 6 by compressing the telescopic rod 7 and the spring 8. Then, the mobile shed 2 is pushed toward the fixed shed 1. When the square sleeve rod 32 and the square sleeve tube 31 are matched, it is only necessary to continue to move the mobile shed 2 until the pin shaft 33 is matched with the through hole 5 to be completely installed. In this process, due to the action of the square ring 34 and the square sleeve tube 31, the pin shaft 33 will not slide out of the mounting hole 6 before matching with the through hole 5, thereby avoiding its interference with the installation.
[0041] In the present invention, preferably, Figure 1 , Figure 2 and Figure 4 As shown, the connecting mechanism 3 further includes a guide rod 35, which is a conical structure. The bottom end of the conical structure is hinged to the end of the square sleeve rod 32, and the size of the bottom end is not greater than the end size of the square sleeve rod 32.
[0042] In this embodiment, the setting of the guide rod 35 with a conical structure can facilitate the positioning during the splicing process of the mobile shed 2 and the fixed shed 1, and further improve the installation efficiency. Specifically, when moving the mobile shed 2, the guide rod 35 will cooperate with the square sleeve rod 32 and the square sleeve tube 31 first. Relative to the size of the square sleeve rod 32, the size of the top of the guide rod 35 is much smaller than the size of the square sleeve rod 32, so it can be easily and quickly inserted into the square sleeve tube 31. Combined with the hinged setting of the end of the guide rod 35 and the square sleeve rod 32, the matching angle can be appropriately adjusted. During splicing, the mobile shed 2 can achieve effective cooperation with the fixed shed 1 even if it is not coaxial or skewed.
