Description
Technical field
The utility model relates to a kind of main shaft and casing connecting structure of monopod video camera.
Background technique
The Cloud Terrace is the support table for installing vidicon camera, the rotation of The Cloud Terrace inner main axis, drive the rotation angle of monopod video camera, to realize the correct shooting to target, the usual belt in one end of main shaft and drive unit are in transmission connection, the direct and housing load of the other end, but when drive unit drives the moment of main axis, the active force that main shaft acts on video camera is larger, and load is comparatively large, there will be belt slippage phenomenon.
Summary of the invention
The purpose of this utility model is that providing a kind of alleviates main axis instantaneously to the active force of video camera, reduces load, avoids belt to occur main shaft and the casing connecting structure of the monopod video camera of skidding.
In order to achieve the above object, the technical solution of the utility model is: a kind of main shaft of monopod video camera and casing connecting structure, comprise video camera, main shaft and housing, video camera is fixedly connected with main shaft by connecting rod, main shaft is connected with housing into rotation, also comprise fastening ring, connecting sleeve, little torsion spring and large torsion spring, fastening ring is fixedly connected with main shaft, connecting sleeve is sleeved on main shaft, and be fixedly connected with housing, connecting sleeve is provided with counterbore, little torsion spring is positioned at counterbore, and one end is fixedly connected with fastening ring, the other end is fixedly connected with connecting sleeve, large torsion spring set is contained on connecting sleeve, and one end is fixedly connected with fastening ring, the other end is fixedly connected with connecting sleeve.
After adopting said structure, because the utility model arranges two torsion springs, when drive unit drives main axis, fastening ring also can and then rotate, because little torsion spring is positioned at counterbore, and one end is fixedly connected with fastening ring, the other end is fixedly connected with connecting sleeve, large torsion spring set is contained on connecting sleeve, and one end is fixedly connected with fastening ring, and the other end is fixedly connected with connecting sleeve, therefore little torsion spring and large torsion spring act on simultaneously, reduce main axis and give the active force that video camera brings instantaneously, alleviate load, avoid belt and occur skidding.
Accompanying drawing explanation
Fig. 1 is partial sectional view of the present utility model.
Embodiment
The embodiment provided below in conjunction with accompanying drawing is described in further detail the utility model.
Shown in Figure 1, a kind of main shaft of monopod video camera and casing connecting structure, comprise video camera 1, main shaft 2 and housing 3, video camera 1 is fixedly connected with main shaft 2 by connecting rod 10, main shaft 2 and housing 3 are rotationally connected, also comprise fastening ring 4, connecting sleeve 5, little torsion spring 6 and large torsion spring 7, fastening ring 4 is fixedly connected with main shaft 2, connecting sleeve 5 is sleeved on main shaft 2, and be fixedly connected with housing 3, connecting sleeve 5 is provided with counterbore 51, little torsion spring 6 is positioned at counterbore 51, and one end is fixedly connected with fastening ring 4, the other end is fixedly connected with connecting sleeve 5, large torsion spring 7 is sleeved on connecting sleeve 5, and one end is fixedly connected with fastening ring 4, the other end is fixedly connected with connecting sleeve 5.
Shown in Figure 1, when video camera 1 of the present utility model works, drive unit drives belt to act on main shaft 2, and main shaft 2 rotates, and drives connecting rod 10 to rotate, and connecting rod 10 drives video camera 1 to rotate.Drive unit of the present utility model is in startup moment, the active force of main shaft 2 and load are all larger, connecting sleeve 5 is when and then main shaft 2 rotates, little torsion spring 6 and large torsion spring 7 act on simultaneously, reduce main shaft 2 and rotate the active force giving video camera 1 instantaneously and bring, alleviate load, avoid belt and occur skidding.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
