Embodiment
Below, in conjunction with the accompanying drawings and embodiment, tripod swivel base of the present utility model is described further, so that clearerly understand the utility model technological thought required for protection.
As shown in Figure 1, be a kind of tripod swivel base of the present utility model, comprise spindle part 1, left-hand rotation seat 2, the seat 3 of turning right, wherein spindle part 1 comprises main shaft 11 and The Cloud Terrace 12, The Cloud Terrace 12, the seat 2 that turns left, the seat 3 of turning right are sleeved on the main shaft 11 from top to bottom successively, The Cloud Terrace 12 clamps with main shaft 11, and the seat 2 that turns left can rotate relative to main shaft 11 with 3 of the seats of turning right.
Turn left and between seat 2 and the The Cloud Terrace 12 an elasticity limit assembly is installed, it comprises a spring 41 and is fixedly connected on spring underpart steel ball spherical in shape 42, in the corresponding position of turn left seat 2 upper surfaces and steel ball 42, be provided with two hemispheric draw-in grooves 21, spring 41 is installed in the hole 121 that is provided with on the The Cloud Terrace 12 in advance, and The Cloud Terrace 12 upper caps are provided with a cover plate 13, and with the upper end portion capping in hole 121, the top free end of spring 41 is then contacted by cover plate 13.In conjunction with shown in Figure 2, the centre of sphere of two draw-in grooves 21 concyclic (concrete be these 2 be positioned at same with main shaft 11 medial axis on the circular arc that is projected as the center of circle of seat 2 upper surfaces that turns left), and its two be 30 degree with the medial axis of main shaft 11 at the angle a of the line of the projection of seat 2 upper surfaces that turn left respectively.Under the original state, steel ball 42 is positioned at one of them draw-in groove 21,41 pairs of steel balls 42 of spring apply downward pressure, when the seat 2 that turns left is applied external force, when it is rotated, 42 of steel balls break away from from this draw-in groove 21, and after the seat 2 that turns left rotated 30 degree with respect to the medial axis of main shaft 11, steel ball 42 fell in the two outer draw-in grooves 21.
In addition, because the staff externally applied forces is difficult to hold, excessive in order to prevent rotation amplitude, Fig. 1 and in conjunction with shown in Figure 3 for another example, upper surface at the seat 2 that turns left is provided with a positive stop lug boss 22, corresponding, be provided with the groove 122 of an arc at the lower surface of The Cloud Terrace 12, the center of circle of groove 122 arc places circle is positioned on the medial axis of main shaft 11, the radian of its arc is 30 degree, and boss 22 is inserted in the groove 122, and seat 2 turns to 30 when spending with respect to main shaft 11 when turning left, then boss 22 is conflicted mutually with the cell wall of groove 122, and the seat 2 that turns left cannot be rotated further with main shaft 11.
As Fig. 1, and in conjunction with Fig. 4, the bottom of main shaft 11 is provided with and turns right and is provided with an elasticity limit assembly between the seat 3, it comprises spring 51, and be fixedly mounted on spring upper end portion steel ball spherical in shape 52, in the corresponding position of the lower surface of the seat 3 of turning right and steel ball 52, be provided with two draw-in grooves 31, spring 51 is installed in the hole of offering main shaft 11 bottoms 111 in advance, the lower ending opening in hole 111 is by a plug 14 shutoff, the bottom free end of spring 51 is contacted by plug 14, two draw-in grooves, 31 centre ofs sphere concyclic (concrete be these 2 be positioned at same with main shaft 11 medial axis on the circular arc that is projected as the center of circle of seat 3 lower surfaces of turning right), and its two be 30 degree with the medial axis of main shaft 11 at the angle a of the line of the projection of seat 3 lower surfaces of turning right respectively, the principle of turning right and rotating mutually between seat 3 and the main shaft 11, identical with above-mentioned left-hand rotation seat 2, do not do repeat specification here.
Same, excessive for the seat rotation amplitude that prevents to turn right, main shaft 11 is provided with a positive stop lug boss 112, and corresponding offers a limited impression 32 on the seat 3 of turning right, and this limited impression 32 is curved, and its radian is 30 degree.
As shown in Figure 5, when above-mentioned tripod swivel base uses, in main shaft, the seat that turns left, the seat bottom of turning right supporting foot is installed respectively, the seat that turns left rotates 30 degree relative to main shaft respectively with the seat of turning right, and then the tripod of Xing Chenging is the most stable.
In addition, at the upper surface of The Cloud Terrace 12, also be provided with a liquid level meter 15, it can judge whether tripod places level by checking liquid level.
