Abstract
The invention relates to an object supporting foot adjustable mechanism, in particular to a self-locking two-way thread adjustable foot margin. The invention comprises a supporting sleeve arranged at the bottom of a foot. The supporting sleeve is fixed on the bottom of the foot and is used to assemble a telescopic adjusting member. The supporting sleeve is immobile relative to the foot or the supported object. The adjusting member moves up and down relative to the supporting sleeve. One end of the adjusting member arranged in the supporting sleeve contacts the ground, and the adjusting member is used to adjust the clearance or the distance between the foot or the supported object and the ground. The adjusting member comprises two thread circular cylinders. One of the circular cylinders is dextrorotatory and the other circular cylinder is levorotatory. A flexible washer is arranged between the two thread circular cylinders. When the clearance between one end of the thread circular cylinder and the ground is eliminated, one end of the thread circular cylinder and the washer are tightly connected with the other end of the thread circular cylinder to tightly lock the thread circular cylinders. The invention is firm, stable and easy to adjust, and has highly capacity of anti-shock and anti-shake. The invention is applicable for a plurality of objects needing being balanced.
Description
Technical field
The present invention relates to object support foot adjusting mechanism, refer in particular to a kind of self locking type bidirectional helical burr adjustable tail margin.
Background technique
The lower margin that uses in the lower margin of document record at present and the real product all is unidirectional adjusting lower margin, so-called unidirectional adjusting is exactly the gap with a joint screw thread up-down adjustment supporting object and ground, as: No. 02248337.3 utility model patent, promptly add a ground runners, form adjustable up and down with a joint screw thread; For another example: 00111279.1 patent of invention of having authorized, also being one is bolted on the rotary sleeve, rotary sleeve is placed on the support pads again, bolt rotates on supporting sleeve with rotary sleeve and regulates bolt and move up and down then, the shortcoming of this structure maximum is exactly that bolt runs into the vibration when long or object rocks or move, bolt is produced slide, become flexible, because bolt is locking not, this unidirectional bolt must be unidirectional moving up and down, the play that will make progress can't walk any longer downwards, time has been grown object and will rock, and produces crippled effect.
Summary of the invention
The objective of the invention is to be improved, innovate, a kind of self locking type bidirectional helical burr adjustable tail margin that has auto-lock function is provided at shortcoming that exists in the background technique and problem.
Technical solution of the present invention is: construct a kind of lower margin that comprises following structural feature:
Be arranged on the bearing sleeve of legs and feet bottoms, bearing sleeve is fixed on the legs and feet bottom, is used to assemble telescopic adjusting member, relative legs and feet of bearing sleeve or to be supported object relatively motionless, and the relative bearing sleeve of adjusting member moves up and down;
Be arranged on the adjusting member in the bearing sleeve, adjusting member one end contacts with ground, is used to regulate the gap or the distance on legs and feet or supported material and ground;
Described adjusting member comprises two joint threaded circular cylinders, wherein a joint is dextrorotation, another joint is for left-handed, in the middle of the two joint threaded circular cylinders flexible gaskets is set, when eliminate in the gap on threaded circular cylinder one end and ground, threaded circular cylinder one end is used for the locking screw cylindrical body with the tight connecting thread cylindrical body the other end of packing ring.
The present invention adopts the threaded adjusting of the opposite rotation direction of two joints, can produce the effect of self-locking, because after the screw thread of bottom mixes up and eliminates ground clearance, again the screw thread on top is regulated downwards, and compress the bolt of bottom by a flexible gaskets, at this moment the screw thread on the screw thread of bottom and top is reverse, when scurrying on the screw thread of bottom, it can drive flexible gaskets and rotate, flexible gaskets can be with the top threads turn again, because the top screw thread is reverse, external force drives it and only can move down, and will produce the tight more effect of lock more.
Description of drawings
Fig. 1 is a stereochemical structure erection drawing of the present invention
Fig. 2 is Fig. 1 exploded
Embodiment
By Fig. 1,2 as can be known, the present invention includes:
Be arranged on the bearing sleeve 1 of legs and feet bottoms, bearing sleeve 1 is fixed on the legs and feet bottom, is used to assemble telescopic adjusting member 2, bearing sleeve 1 relative legs and feet or to be supported object relatively motionless, and adjusting member 2 relative bearing sleeves 1 move up and down;
Be arranged on the adjusting member 2 in the bearing sleeve 1, adjusting member 2 one ends contact with ground, are used to regulate the gap or the distance on legs and feet or supported material and ground;
Described adjusting member 2 comprises two joint threaded circular cylinders 4,5, wherein a joint is dextrorotation, another joint is for left-handed, in the middle of the two joint threaded circular cylinders flexible gaskets 3 is set, when eliminate in the gap on threaded circular cylinder 4 one ends and ground, threaded circular cylinder 5 one ends are used for locking screw cylindrical body 4 with packing ring 3 tight connecting thread cylindrical body 4 the other ends.
Be provided with two joint internal threads in the bearing sleeve 1 of the present invention, the bottom internal thread connects the threaded circular cylinder 4 of adjusting member 2, is dextrad screw thread or left-hand screw thread, and top internal thread connecting thread cylindrical body 5 is left-hand screw thread or dextrad screw thread.Both sides, described bearing sleeve 1 top have window 6, are used to regulate threaded circular cylinder 5 and move up and down.Described threaded circular cylinder 4 bottoms are hemisphere supporting surface 7, or the disk supporting face, and supporting surface top is a hex head bolt head 8, are used to regulate threaded circular cylinder 4 and move up and down.Described thread cylinder 5 tops are a kuruling knob head 9, and end face also is provided with position, hexagon socket head cap screw hole 10, are used to regulate thread cylinder 5 and move up and down.
Member of the present invention can partly or entirely adopt iron and steel or other suitable material, and such as plastics, escapable cost improves shock resistance.In use, threaded circular cylinder 4 is rotated down is tight against ground to lifting flat institute supporting object earlier, then threaded circular cylinder 5 downward hand-screws in top extremely are right after with threaded circular cylinder 4, screw with inner hexagon spanner, then whole lower margin is fixed.The present invention compares with previous patent, and is more firm, stable, easily regulate, more anti-vibration, anti-shaking, more applicable to many need in vibration, shake in use and need the object of balance.
Embodiment of the present invention only is the description that preferred implementation of the present invention is carried out; be not that design of the present invention and scope are limited; do not breaking away under the preceding topic of design philosophy of the present invention; engineers and technicians make technological scheme of the present invention in related domain various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
