Background technique
By being connected on equipment outward or the operating table be arranged near equipment carries out password input to main equipment on main equipment production line, this operating table has display screen, operating box etc., this kind of operating table is generally connected with other equipment by pivoted arm, pivoted arm inside is through cable, operating table can turn round by pivoted arm relatively, but in actual use, if the relative pivoted arm complete cycle revolution of operating table, there is the phenomenons such as winding in the cable that will also exist in pivoted arm, very likely causes the problem that cable breakage occurs or disconnects with operating table.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of operating table cantilever structure, can limit the relative pivoted arm complete cycle revolution of operating table.
For solving the problems of the technologies described above, technological scheme of the present invention is: operating table cantilever structure, comprise the pivoted arm that inside is installed with cable and the bracket be positioned at above described pivoted arm, its innovative point is: arrange limited complete cycle revolving structure between described pivoted arm and described bracket, described limit complete cycle revolving structure comprises the mandrel that central axis is vertically arranged, the sleeve of empty set on described mandrel, be positioned at the bearing between described sleeve and described mandrel, this mandrel lower end clamping bolt is bolted on described pivoted arm, gap is left between this mandrel upper end and described bracket, this sleeve upper end is bolted on described bracket, the floating bearing propping up and described sleeve lower end and mandrel are preset the shaft shoulder is provided with between this sleeve lower end and described mandrel lower end, this sleeve lower end is provided with the flange with described sleeve one, described flange is provided with the limiting stopper propping up described clamping bolt when described sleeve rotating.
Preferably, on described flange, ring flange is at least provided with 2 described limiting stoppers for one week, and described limiting stopper is embedded in the mounting hole that this flange is preset.
Preferably, described mounting hole is the hole of the up/down perforation of U-shaped profile.
Preferably, described hole penetrates on the periphery of described flange.
Preferably, the bearing described in 2 is at least provided with between described sleeve and described mandrel.
Preferably, spacer is provided with between described bearing and bearing.
The invention has the advantages that: mandrel lower end bolt is on pivoted arm, mandrel is through in sleeve, sleeve upper end is fixed on operating table, by arranging bearing between mandrel and sleeve, and guarantee that mandrel upper end does not prop up operating table, the axial restraint of sleeve lower end is propped up on the shaft shoulder default on mandrel by floating bearing.For realizing complete cycle restriction revolution, arrange limiting stopper by holding under a bushing, this limiting stopper is at sleeve rotating to just in time propping up during certain position on clamping bolt that mandrel is connected with pivoted arm, thus the complete cycle realizing limiting the relative pivoted arm of operating table turns round.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Fig. 1 is the structural representation of a kind of operating table cantilever structure of the present invention.
Fig. 2 is the worm's eye view assembling sleeved sleeve in a kind of operating table of the present invention cantilever structure.
In figure: 1-pivoted arm, 2-bracket, 3-mandrel, 4-sleeve, 5-bearing, the 6-shaft shoulder, 7-floating bearing, 8-flange, 9-clamping bolt, 10-limiting stopper, 11-mounting hole, 12-spacer.
Embodiment
Operating table cantilever structure of the present invention, comprises the pivoted arm 1 that inside is installed with cable and the bracket 2 be positioned at above pivoted arm 1.In order to limit pivoted arm 1 relatively and bracket 2 complete cycle turn round, limited complete cycle revolving structure is set between pivoted arm 1 and bracket 2, this limit complete cycle revolving structure comprises the mandrel 3 that central axis is vertically arranged, the sleeve of empty set on mandrel 3, be positioned at the bearing 5 between sleeve and mandrel 3, this mandrel lower end clamping bolt 9 is bolted on pivoted arm 1, gap is left between this mandrel upper end and bracket 2, this sleeve upper end is bolted on bracket 2, the floating bearing 7 propping up and sleeve lower end and mandrel 3 are preset the shaft shoulder 6 is provided with between this sleeve lower end and mandrel lower end, this sleeve lower end is provided with the flange 8 with sleeve one, flange 8 is provided with the limiting stopper 10 propping up clamping bolt 9 when sleeve rotating.
In said structure, sleeve upper end realizes axis by bolt and bracket 2 and circumference is located, sleeve lower end realizes axially locating by floating bearing 7 and mandrel 3, mandrel lower end to be connected with pivoted arm 1 by clamping bolt 9 and to realize axial and circumferential and locate, mandrel upper end does not contact bracket 2, bearing 5 is set between mandrel 3 and sleeve thus mandrel 3 relative sleeve realizing being connected with pivoted arm 1 realizes turning round, concrete turns round to realize complete cycle, by holding under a bushing, limiting stopper 10 is set, and ensure the end face of limiting stopper 10 bottom surface lower than clamping bolt 9, thus when the relative pivoted arm 1 of operating table turns round, limiting stopper 10 touches clamping bolt 9 and namely stops revolution.
In order to realize the restriction limiting angle of revolution, on flange 8, ring flange is at least provided with 2 limiting stoppers 10 for 8 one weeks, and limiting stopper 10 is embedded in the mounting hole that this flange 8 is preset, thus flange 8 complete cycle can be divided into some angles by multiple limiting stopper 10.
For the ease of installing, mounting hole is the hole of the up/down perforation of U-shaped profile, and this hole penetrates on the periphery of flange 8, thus limiting stopper 10 can facilitate the hole of the direct up/down perforation along taking the shape of the letter U to be embedded in this hole.
In order to realize the gyroscopic effects of sleeve and mandrel 3, being at least provided with the bearing 5 of 2 between sleeve and mandrel 3, and being provided with spacer 12 between bearing 5 and bearing 5.
Specific operation process: mandrel lower end bolt is on pivoted arm 1, mandrel 3 is through in sleeve, sleeve upper end is fixed on operating table, by arranging bearing 5 between mandrel 3 and sleeve, and guarantee that mandrel upper end does not prop up operating table, the axial restraint of sleeve lower end is propped up on the shaft shoulder 6 default on mandrel 3 by floating bearing 7.For realizing complete cycle restriction revolution, arrange limiting stopper 10 by holding under a bushing, this limiting stopper 10 is at sleeve rotating to just in time propping up during certain position on clamping bolt 9 that mandrel 3 is connected with pivoted arm 1, thus the complete cycle realizing limiting the relative pivoted arm 1 of operating table turns round.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope all belonging to the invention.
