Abstract
The utility model relates to a long-travel three-level oil cylinder device for an operating table. The long-travel three-level oil cylinder device comprises an internal core cylinder, a central cylinder and an external cylinder, wherein the central cylinder is arranged outside the internal core cylinder; the external cylinder is arranged outside the central cylinder; two ends of the internal core cylinder are connected with the central cylinder through first sealing pieces; the two ends of the central cylinder are connected with the external cylinder through second sealing pieces; a first oil entry and exit port and a second oil entry and exit port are symmetrically arranged at the two ends of the external cylinder; and the external cylinder is installed between a bed frame and a movable bracket through an installation seat. The long-travel three-level oil cylinder device for the operating table has the advantages of low noise, convenience for installation and longer travel.
Description
Technical field:
The utility model discloses a kind of three grades of cylinder apparatus of big stroke that are used for operating table.
Background technique:
Electro-hydraulic operation table is arranged in the market, and translation functions still relies on electric pushrod to realize, as reaching certain stroke, the installation dimension of push rod is just bigger than normal, and installing space is not enough, and noise is bigger than normal.Consider to adopt the structure of hydraulic jack, noise can obviously reduce, and the dress size is also bigger than normal.
Summary of the invention:
The purpose of the utility model is in order to overcome above deficiency, a kind of needs that both can satisfy big stroke to be provided, can satisfying three grades of cylinder apparatus of the big stroke that is used for operating table of installation dimension needs again.
The purpose of the utility model realizes through following technological scheme: a kind of three grades of cylinder apparatus of big stroke that are used for operating table; Comprise inner canister, central tube and urceolus; Be provided with central tube in the inner canister outside; Be provided with urceolus in the central tube outside, the two ends of inner canister are connected with central tube through first Sealing, and the two ends of central tube are connected with urceolus through second Sealing; Be arranged with first oil inlet and outlet and second oil inlet and outlet at the urceolus two ends, urceolus is installed between bedstead and the travel(l)ing rest through fitting seat.
The utility model compared with prior art has the following advantages:
The use noise is little, and it is little to be reduced to the most in short-term self size, can easily realize the little spatial requirement that takies on the installation dimension, and oil cylinder reaches when the longest, and one times of the stroke lengthening of the original two-level oil cylinder of stroke ratio can satisfy the needs of big stroke simultaneously.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Label among the figure: 1-inner canister, 2-SMIS tube, 3-urceolus, 4-first Sealing, 5-second Sealing, 6-first oil inlet and outlet, 7-second oil inlet and outlet, 8-fitting seat.
Embodiment:
In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is done further to detail below, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Show a kind of a kind of mode of execution that is used for three grades of cylinder apparatus of big stroke of operating table of the utility model like Fig. 1; Comprise inner canister 1, central tube 2 and urceolus 3; Be provided with central tube 2 in inner canister 1 outside; Be provided with urceolus 3 in central tube 2 outsides, the two ends of inner canister 1 are connected with central tube 2 through first Sealing 4, and the two ends of central tube 2 are connected with urceolus 3 through second Sealing 5; Be arranged with first oil inlet and outlet 6 and second oil inlet and outlet 7 at urceolus 3 two ends, urceolus 3 is installed between bedstead and the travel(l)ing rest through fitting seat 8.
Inner canister 1, central tube 2 and urceolus 3 have been formed three grades of oil cylinders, and when 6 oil-feeds of first oil inlet and outlet, second oil inlet and outlet 7 is fuel-displaced simultaneously; Form the oil circuit loop, separate oil circuit through the Sealing on SMIS tube 2 and the inner canister 1, oil supply system fuel feeding promotion SMIS tube 2 and inner canister 1 be indentation urceolus 3 step by step; To reach the effect that oil cylinder shrinks; When from 7 oil-feeds of second oil inlet and outlet, first oil inlet and outlet 6 is fuel-displaced simultaneously conversely, forms the loop; Action becomes inner canister 1 stretches out with central tube 2 step by step, has reached the effect of oil cylinder elongation.When in inner canister 1 and the central tube 2 whole indentation urceolus 3, the total length of oil cylinder is the length of urceolus 3 basically, and such size suits for installation.
The utlity model has and use noise little; It is little to be reduced to the most in short-term self size, can easily realize the little spatial requirement that takies on the installation dimension, and oil cylinder reaches when the longest; One times of the stroke lengthening of the original two-level oil cylinder of stroke ratio, the while can be satisfied the advantage of the needs of big stroke.
