[embodiment]

The present invention is further illustrated below in conjunction with drawings and Examples.

With reference to figure 1, The Cloud Terrace locking device 1000 provided by the invention comprises base 100, be installed in trimming assembly 200 on the base 100, be installed in the rough adjustment feature 300 on the trimming assembly 200 and be fixed on the straight tube The Cloud Terrace 400 on rough adjustment feature 300 tops.

With reference to figure 1-4, base 100 is used to support above-mentioned trimming assembly 200, rough adjustment feature 300 and straight tube The Cloud Terrace 400.Described base 100 comprises chassis 102 with groove 1022, be placed on gasket ring 104 in the described groove 1022, be placed on liner 106 on the gasket ring 104, radially screw in the anti-turn screw 109 in the liner 106 and be placed on clamp ring 108 on the liner 106.By anti-turn screw 109 tightly is screwed on the liner 106, can prevent the rotation of liner 106, thus liner 106 is fixing.

With reference to figure 1 and Fig. 5, trimming assembly 200 comprises Thrust ring 202 in the middle of the clamp ring 108 that is stuck in base 100, be arranged on the conical ring 204 in the Thrust ring 202 and be supported in the force-transmitting pole 206 at conical ring 204 tops.

Described Thrust ring 202 comprises first annular sidewall 2026 and fastens neck 2024 from first annular sidewall 2,026 first of two the spaced-apart certain distances forming that extend radially outwardly.Form inner conical surface 2022 on the internal surface of described first annular sidewall 2026.Described two first fastening necks 2024 are connected to each other by micrometer adjusting screw 208.

The conical surface portion 2044 corresponding with the inner conical surface 2022 of described Thrust ring 202 formed on the bottom of described conical ring 204, and conical ring 204 is arranged on the inner conical surface 2022 of Thrust ring 202, thus the formation cone match.

When described micrometer adjusting screw 208 being tightened in described two first when fastening necks 2024, described two first distances that fasten between the neck 2024 reduce, thereby cause Thrust ring 202 to shrink, and then make the conical surface portion 2044 of inner conical surface 2022 extruding conical rings 204, the result of this extruding causes conical ring 204, force-transmitting pole 206 axially to move up, because the fixed-site of spheric seat 308 is motionless, therefore cause member between spheric seat 308 and the force-transmitting pole 206 by axial compression, thereby effectively prevented its rotation.

With reference to figure 1 and Fig. 6, rough adjustment feature 300 comprises pushing away circle 302, be arranged on and describedly push away the cone 304 of circle in 302, be arranged on the cylinder base 306 on the cone 304 and be arranged on spheric seat 308 in the cylinder base 306 on the force-transmitting pole 206 that is arranged on trimming assembly 200.

The described circle 302 that pushes away comprises second annular sidewall 3026 and fastens neck 3024 from second annular sidewall 3,026 second of two the spaced-apart certain distances forming that extend radially outwardly.Form circular cone 3022 on the internal surface of described second annular sidewall 3026.Described two second fastening necks 3024 are connected to each other by coarse adjustment screw 301.

Described cone 304 is arranged on described pushing away on circle 302 the circular cone 3022, thereby between forms cone match.

When described coarse adjustment screw 301 being tightened in described two second when fastening necks 3024, described two second distances that fasten between the neck 3024 reduce, thereby causing pushing away circle 302 shrinks, and then make circular cone 3022 push whole cone 304, the result of this extruding causes cone 304, cylinder base 306 axially to move up, because the fixed-site of spheric seat 308 is motionless, therefore causes member between spheric seat 308 and the cylinder base 306 by axial compression, thereby effectively prevented its rotation.

In addition, described straight tube The Cloud Terrace 400 is placed on the spheric seat 308 of described rough adjustment feature 300.Offer a plurality of fixed holes 402 on the circumferential surface of described straight tube The Cloud Terrace 400, the assembly in the straight tube The Cloud Terrace 400 can be fixed by fastening screw trip bolt 404 being screwed in the fixed hole 402.

Since trimming assembly 200 and rough adjustment feature 300 can axial adjustment The Cloud Terrace locking device 1000 axial tightness, therefore greatly facilitate user's adjustment process.And simple in structure, regulate quick and safe and reliable.
