【Detailed ways】

The present invention will be further described below in conjunction with the accompanying drawings and embodiments. the

With reference to Fig. 1, the pan-tilt locking device 1000 provided by the present invention includes a base 100, a fine adjustment assembly 200 installed on the base 100, a coarse adjustment assembly 300 installed on the fine adjustment assembly 200, and a straight cloud fixed on the top of the coarse adjustment assembly 300. Taiwan 400. the

Referring to FIGS. 1-4 , the base 100 is used to support the above-mentioned fine adjustment assembly 200 , coarse adjustment assembly 300 and straight pan-tilt 400 . The base 100 includes a chassis 102 with a groove 1022, a backing ring 104 placed in the groove 1022, a lining 106 placed on the backing ring 104, and an anti-rotation screw 109 radially screwed into the lining 106 And the locking ring 108 placed on the lining 106. By tightening the anti-rotation screw 109 tightly on the lining 106, the lining 106 can be prevented from rotating, thereby fixing the lining 106. the

Referring to FIG. 1 and FIG. 5 , the trimming assembly 200 includes a thrust ring 202 clamped in the locking ring 108 of the base 100 , a conical ring 204 disposed in the thrust ring 202 , and a force transmission post 206 supported on the top of the conical ring 204 . the

The thrust ring 202 includes a first annular sidewall 2026 and two first fastening necks 2024 extending radially outward from the first annular sidewall 2026 with a certain distance from each other. An inner tapered surface 2022 is formed on an inner surface of the first annular sidewall 2026 . The two first snap-fit necks 2024 are interconnected by fine-tuning screws 208 . the

The bottom of the cone ring 204 forms a cone surface 2044 corresponding to the inner cone surface 2022 of the thrust ring 202 , and the cone ring 204 is arranged on the inner cone surface 2022 of the thrust ring 202 to form a cone fit. the

When the fine-tuning screw 208 is tightened on the two first fastening necks 2024, the distance between the two first fastening necks 2024 is reduced, thereby causing the thrust ring 202 to shrink, thereby making The inner cone surface 2022 squeezes the cone surface 2044 of the cone ring 204. As a result of this extrusion, the cone ring 204 and the force transmission column 206 move upward axially. Since the position of the spherical seat 308 is fixed, the spherical seat 308 The components between the force transmission column 206 are axially squeezed, thereby effectively preventing it from rotating. the

1 and 6, the coarse adjustment assembly 300 includes a push ring 302 arranged on the force transmission column 206 of the fine adjustment assembly 200, a cone 304 arranged in the push ring 302, and a cylinder seat arranged on the cone 304 306 and the spherical seat 308 arranged in the cylinder seat 306. the

The push ring 302 includes a second annular sidewall 3026 and two second fastening necks 3024 extending radially outward from the second annular sidewall 3026 with a certain distance from each other. An annular tapered surface 3022 is formed on the inner surface of the second annular sidewall 3026 . The two second fastening necks 3024 are connected to each other by a coarse adjustment screw 301 . the

The taper 304 is disposed on the annular taper surface 3022 of the push ring 302 so as to form a taper fit between the two. the

When the coarse adjustment screw 301 is tightened on the two second fastening necks 3024, the distance between the two second fastening necks 3024 decreases, thereby causing the push ring 302 to contract, and then The annular cone surface 3022 squeezes the entire cone 304. As a result of this extrusion, the cone 304 and the cylinder seat 306 move axially upwards. Since the position of the spherical seat 308 is fixed, the spherical seat 308 and the cylinder seat The components between 306 are axially squeezed, thereby effectively preventing their rotation. the

In addition, the straight pan head 400 is placed on the spherical seat 308 of the coarse adjustment assembly 300 . A plurality of fixing holes 402 are provided on the peripheral surface of the straight-cylinder head 400 , and components in the straight-type head 400 can be fixed by screwing fastening screws 404 into the fixing holes 402 . the

Since both the fine adjustment assembly 200 and the coarse adjustment assembly 300 can axially adjust the axial tightness of the pan/tilt locking device 1000 , it greatly facilitates the user's adjustment process. Moreover, the structure is simple, the adjustment is quick and safe and reliable. the
