Abstract
The utility model provides a stroke adjustable rotatable connecting structure, includes the case lid, and the below of case lid is provided with the box, and the top of box is provided with the sealing strip, and the right -hand member face of case lid is provided with the nut backup pad, is provided with the through -hole that the several was arranged along the fore -and -aft direction equidistance in the nut backup pad, all is provided with the screw rod in the through -hole, and the top of screw rod all is provided with gland nut, and the rear of screw rod is provided with the hinge, and it has lower hinge through the hinge hub connection to go up the hinge, and lower hinge fixes the right -hand member face at the box, gland nut's outer lane sets up to outer hexagonal, diameter of hole in the nut backup pad is greater than the external diameter of screw rod. The utility model discloses rational in infrastructure, ingenious, stroke control makes things convenient for, improves sealing performance between the connecting piece, has avoided cryrogenic case low temperature to contract the sealed problem that arouses, has reduced the energy consumption, popularizes and applies to have good economy and social.
Description
Technical field
The utility model belongs to deep cold treatment apparatus technical field, relates to a kind of rotary connection structure, the rotary connection structure that particularly a kind of stroke is adjustable.
Background technology
Hinge, as a kind of conventional rotary connection structure, is widely used on mechanical equipment.And the hinge of routine be connected structure for being fixedly connected with, cannot realize connecting the adjustment of tightness.Some are existed to the mechanical equipment of obvious temperature traverse, as deep cold treatment apparatus, time temperature reduces, owing to shrinking under body structure low temperature, thus closing structure junction can be caused to fluff, good low temperature sealing cannot be realized, cause energy dissipation.
Summary of the invention
The purpose of this utility model to solve the problems of the technologies described above.
The purpose of this utility model is achieved in that the rotary connection structure that a kind of stroke is adjustable, comprise case lid, the below of case lid is provided with casing, the top of casing is provided with sealing band, it is characterized in that: the right side of described case lid is provided with nut support plate, nut support plate is provided with several through hole along fore-and-aft direction equidistant placement, screw rod is provided with in through hole, the top of screw rod is provided with hold-down nut, the rear of screw rod is provided with hinge, upper hinge is connected with lower jaw by hinge axis, and lower jaw is fixed on the right side of casing.
The outer ring of described hold-down nut is set to outer-hexagonal.
Through-hole diameter on described nut support plate is greater than the external diameter of screw rod.
The utility model is rational in infrastructure, ingenious, stroke adjustment convenient, improve sealing property between attaching parts, avoids the sealing problem that deep cooling box low-temperature shrink causes, decreases energy consumption, apply and have good economic and social benefit.
Accompanying drawing explanation
Fig. 1 is mounting structure front view of the present utility model.
Fig. 2 is the A partial enlarged drawing of Fig. 1.
Fig. 3 is the right elevation of Fig. 2.
In figure: 1. case lid; 2. hold-down nut; 3. nut support plate; 4. screw rod; 5. hinge axis; 6. lower jaw; 7. casing; 8. sealing band.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to restriction of the present utility model:
The rotary connection structure that a kind of stroke is adjustable, comprise case lid 1, the below of case lid 1 is provided with casing 7, the top of casing 7 is provided with sealing band 8, the right side of described case lid 1 is provided with nut support plate 3, nut support plate 3 is provided with several through hole along fore-and-aft direction equidistant placement, screw rod 4 is provided with in through hole, the top of screw rod 4 is provided with hold-down nut 2, the rear of screw rod 4 is provided with hinge, upper hinge is connected with lower jaw 6 by hinge axis 5, and lower jaw 6 is fixed on the right side of casing 7; The outer ring of described hold-down nut 2 is set to outer-hexagonal; Through-hole diameter on described nut support plate 3 is greater than the external diameter of screw rod 4.
During concrete enforcement, can realize by screw rod 4, upper hinge, hinge axis 5, lower jaw 6 rotor switch that case lid 1 is axle center with hinge axis 5; Case lid 1 can be pressed down by rotatably compressing nut 2 when being sealed with gap between case lid 1 and casing 7, realizing case lid 1 and the sealing of casing 7, solving the poor sealing problem that deep freeze refrigeration plant causes due to low-temperature shrink.
Obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here exhaustive without the need to also giving all embodiments, and thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
