Abstract
The utility model discloses a light centrifugal machine door cover hinge which comprises an upper hinge, a rotary shaft, a lower hinge, a support shaft, a clamp slot, an adjusting screw rod, an adjusting nut, a support spring and a rotary block; the upper hinge is fixedly connected with a centrifugal machine door cover, one end of the support shaft is arranged in the clamp slot, the clamp slot is arranged on the upper end of the adjusting screw rod, the support shaft penetrates through the upper hinge hole, and then both ends of the support shaft are arranged in the circular arc-shaped slots on both sides of the lower hinge, the rotary shaft penetrates through the upper hinge hole, and then both ends of the rotary shaft are fixedly welded with the both sides of the lower hinge, the support spring is nested on the adjusting screw rod, the adjusting nut is mounted on the adjusting screw rod, the adjusting screw rod can be adjusted on the adjusting screw rod up and down, the support spring is arranged under the adjusting nut, and the lower end of the adjusting screw rod extends out of the rotary block to be lapped on the inner flange holes on both sides of the lower hinge; and the light centrifugal machine door cover hinge has the advantages of simple structure, labor saving property, convenience and safety.
Description
Technical field
The utility model relates to the door lock hinge, relates in particular to a kind of portable centrifuge door closure hinge.
Background technology
At present, be connected with ready-made hinge between known centrifuge door closure and the body, the operator requires great effort when opening door closure very much, especially some big-and-middle-sized frozen type centrifuges, because these machines are in order to guarantee refrigeration, usually thickening is taked in design on door closure, special measures such as insulation, make door closure very heavy, and the sampling of just letting go more than after opening the door, must making door closure and body becomes an angle of 90 degrees, otherwise door closure can be because own wt covers once more suddenly automatically, if the operator does not note just may injuring health slightly, bring very big potential safety hazard to operating personnel.
The utility model content
In order to overcome the defective of above-mentioned prior art, the utility model provides a kind of portable centrifuge door closure hinge, comprise upper hinge, turning cylinder, following hinge, back shaft, draw-in groove, adjusting screw(rod), adjusting nut, support spring and spill spin block, described upper hinge is fixedlyed connected with the centrifuge door closure, described back shaft one end is arranged in the draw-in groove, described draw-in groove is arranged on the adjusting screw(rod) upper end, two ends were arranged on down in the arc-shaped slot of hinge both sides after described back shaft passed the upper hinge hole, two ends were fixing with the welding of following hinge both sides after described turning cylinder passed the upper hinge hole, described support spring is enclosed within on the adjusting screw(rod), described adjusting nut is installed on the adjusting screw(rod), described adjusting screw(rod) can be on adjusting screw(rod) up-down adjustment, described support spring is located at the adjusting nut below, and described adjusting screw(rod) lower end passes spill spin block and rides over down on the in-flanges hole, hinge both sides.
The utility model is to fixedly connected with the centrifuge door closure by the upper hinge joint face, when needs open the door, lifting door closure, can to drive upper hinge be that rotate in the axle center with the turning cylinder, along with upper hinge is the continuous angle changing in axle center with the turning cylinder, make back shaft also change its position accordingly thereupon, formation is the center of circle with the turning cylinder central point, the turning cylinder central point is the movement in a curve of radius to the back shaft central point, as needs downwards at closing time, the downward squeeze adjustments screw rod of back shaft, support spring compression is shortened and gather elastic force (the big I of elastic force is controlled and regulated support spring and is achieved by adjusting nut), this moment, spring self length shortened, and the length of adjusting screw(rod) also shortens thereupon, makes door closure shut very like a cork, when to upward-acting door, gather big elastic force because support spring inside is squeezed, this moment, spring began to release energy, and made that spring self length is elongated, adjusting screw(rod) is also corresponding thereupon elongated, makes door closure be strutted.
The following beneficial effect of the utility model in sum:
1, simple in structure, laborsaving, easy to use;
2, safe.
Description of drawings
Fig. 1 is the structural representation of the portable centrifuge door closure of the utility model hinge.
Wherein: 1-upper hinge, 2-turning cylinder, hinge under the 3-, 4-back shaft, 5-draw-in groove, 6-adjusting screw(rod), 7-adjusting nut, 8-support spring, 9-spill spin block.
The specific embodiment
Portable centrifuge door closure hinge as shown in Figure 1, comprise upper hinge 1, turning cylinder 2, following hinge 3, back shaft 4, draw-in groove 5, adjusting screw(rod) 6, adjusting nut 7, support spring 8 and spill spin block 9, described upper hinge 1 is fixedlyed connected with the centrifuge door closure, described back shaft 4 one ends are arranged in the draw-in groove 5, described draw-in groove 5 is arranged on adjusting screw(rod) 6 upper ends, two ends were arranged on down in the hinge 3 both sides arc-shaped slots after described back shaft 4 passed upper hinge 1 hole, two ends were fixing with the welding of following hinge 3 both sides after described turning cylinder 2 passed upper hinge 1 hole, described support spring 8 is enclosed within on the adjusting screw(rod) 6, described adjusting nut 7 is installed on the adjusting screw(rod) 6, described adjusting nut 7 can be on adjusting screw(rod) 6 up-down adjustment, described support spring 8 is located at adjusting nut 7 belows, and described adjusting screw(rod) 6 lower ends pass spill spin block 9 and ride over down on the in-flanges hole, hinge 3 both sides.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this manual has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of utility model, and it all should be encompassed in the middle of the claim scope of the present utility model.
