Description
Technical field
The utility model belongs to medical science apparatus technical field, relates to a kind of medical bed plate bindiny mechanism.
Background technique
In the medical field, this sick bed is made up of lifting bed board and fixed bed board in lifting hospital bed extensive use, and at present, the method that lifting bed board is connected with fixed bed board is that chain connection or bolt connect.Time with bolts, lifting bed board and fixed bed board coordinate with bolt-through.If the tension that nut is twisted, inconvenience when easily causing rotating between two bed boards, when what nut was twisted crosses pine, although two bed boards can freely rotate, but nut is stressed comparatively large, and long-time use can cause nut to get loose, and causes unthinkable consequence.
Model utility content
For solving above technical problem, the utility model provides a kind of medical bed plate bindiny mechanism, and wherein one piece of bed board maintains static, and another block bed board freely rotates, and make nut stressed relatively little like this, and installation and removal is also very convenient.
Its technological scheme is as follows:
A kind of medical bed plate bindiny mechanism, comprise the first bed board fixed plate and the second bed board fixed plate, it is characterized in that: described first bed board fixed plate and the second bed board fixed plate are equipped with attachment hole, run through in the attachment hole of the first bed board fixed plate and the second bed board fixed plate and have shoulder bolt, this shoulder bolt is formed in one formation, by round boss head, smooth stepped part and screw part are connected in sequence, this smooth stepped part diameter is greater than screw part diameter, attachment hole and the smooth stepped part of described first bed board fixed plate are rotatably assorted, the attachment hole of described second bed board fixed plate is set in screw part, and pass through fastening nuts.Adopt above-mentioned technology, achieve one piece of bed board and fix, the requirement that another block bed board is free to rotate.
Further, described round boss head cambered surface center offers interior hexagon counterbore vertically.Such design is convenient to fastening, dismounting, is not easy sliding angle.
Further, described smooth stepped part length is greater than the first bed board fixed plate thickness.Make the first bed board fixed plate energy flexible rotating being arranged on smooth step section.
Further, described washer center bore dia is between the diameter and the diameter of smooth stepped part of screw part, use packing ring expand the second bed board fixed plate and smooth step end face surface of contact, to reduce fastening force concentrated to the stress of fastener, prevents damage fastener.
Further, described packing ring adopts the material such as rubber or asbestos, and because nonmetallic material quality is soft, corrosion-resistant, low price, so more applicable.
The beneficial effects of the utility model are:
The utility model solves bolt when fixing, and bed board rotates inconvenience or the stressed large problem of nut, and the utility model installation and removal are also more convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is shoulder bolt structural representation of the present utility model;
Fig. 3 is the first bed board fixed plate schematic diagram of the present utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
A kind of medical bed plate bindiny mechanism as shown in Figure 1, comprise the first bed board fixed plate 1 and the second bed board fixed plate 2, described first bed board fixed plate 1 and the second bed board fixed plate 2 are separately fixed on two pieces of interconnective bed boards, described first bed board fixed plate 1 and the second bed board fixed plate 2 are equipped with attachment hole 6, run through in the attachment hole 6 of the first bed board fixed plate 1 and the second bed board fixed plate 2 and have shoulder bolt 3, this shoulder bolt 3 is formed in one formation, by round boss head 31, smooth stepped part 32 and screw part 33 are connected in sequence, this smooth stepped part 32 diameter is greater than screw part 33 diameter, the attachment hole 6 of described first bed board fixed plate 1 coordinates with smooth stepped part 32, the attachment hole 6 of described second bed board fixed plate 2 is set in screw part 33, and it is fastening by nut 5.
As shown in Figure 2, described shoulder bolt 3 is structure as a whole, comprise the round boss head 31, smooth stepped part 32 and screw part 33 3 part that connect successively, described smooth step 32 diameter is greater than screw part 33 diameter, the attachment hole 6 of described first bed board fixed plate 1 coordinates with smooth stepped part 32, and the attachment hole 6 of described second bed board fixed plate 2 is set in screw part 33.
In the present embodiment, the length of shoulder bolt 3 preferred smooth stepped part 32 is greater than the thickness of the first bed board fixed plate 1, along round boss head 31 cambered surface central shaft to offering interior hexagon counterbore 34.
As shown in Figure 3, the overall semicircular in shape sheet of this first bed board fixed plate 1, and center is equipped with attachment hole 6, described first bed board fixed plate 1 is identical with the second bed board fixed plate 2 structure.
Working principle of the present utility model is as follows:
First, first bed board fixed plate 1 and the second bed board fixed plate 2 are welded on two pieces of bed boards respectively, shoulder bolt 3 are penetrated from the attachment hole 6 the first bed board fixed plate 1, is inserted in packing ring 4, again screw rod 33 is passed the attachment hole 6 on the second bed board fixed plate 2, and fix with nut 5.When controlling bed board up-down adjustment, this bed board can rotate around shoulder bolt 3.When nut 5 is tightened, the second bed board fixed plate 2 end face and smooth stepped part end face are adjacent to, and the second bed board fixed plate 2 is fixed with boss bolt, and the attachment hole of the first bed board fixed plate 1, rotates for axle with smooth stepped part.
Finally it should be noted that; foregoing description is only preferred embodiment of the present utility model; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite without prejudice to the utility model aim and claim; can make like multiple types and representing, such conversion all falls within protection domain of the present utility model.
