Abstract
The utility model provides a wear-resisting type box door hinge, which comprises a base board and a door frame, wherein the base board and the door frame are hinged movably through a first hinge; a pull rod is movably hinged on the base board through a third hinge; the wear-resisting type box door hinge is characterized in that a roller wheel is movably hinged on the top end of the pull rod through a second hinge; the roller wheel can rotate freely on a second hinge shaft; and the roller wheel is arranged inside a slide groove of the door frame to slide in the slide groove. A shaft sleeve is arranged on the door frame; the shaft sleeve is sleeved on the hinge shaft of the first hinge to rotate; and the two end faces of the shaft sleeve are contacted with the inner side of a bracket of the base board. The wear-resisting type box door hinge has the beneficial effects that (1) the wear-resisting type box door hinge has the advantages of simple structure, installation convenience and low production cost; (2) the door frame, the pull rod and the base plate are connected through a shaft sleeve, the shaft sleeve is sleeved on the hinge shaft, the contact area is enlarged effectively, and the partial pressure intensity is reduced, so that the wear-resistance is improved so as to prolong the service life of the hinge; and (3) the two ends of the shaft sleeve support against the inner side plane of the bracket, so that the bracket is prevented from moving left and right, and the door frame is prevented from shaking even distortion.
Description
Technical field
The utility model relates to the closing hinge that a kind of casing chamber door is used, and specifically is a kind of wear-resisting type chamber door hinge.
Background technology
At present, in the box electrical equipment of all band doors, like electric oven; Micro-wave oven etc. become household appliances commonly used one of them; Be exactly nothing but to be divided into base plate and door frame in the chamber door hinge of these electrical equipment, through the hinge active link, its hinge form is through on door frame, offering circular hole usually between base plate; One rivet passes circular hole it is hinged on the support, and door frame can rotate round rivet and reach the purpose of opening or closing chamber door.Because chamber door has constant weight and hinge to need frequent the rotation, rivet is in stationary state again, so rivet very easily is worn, or even fracture, has had a strong impact on its application life.Moreover door frame can also jump about on the rivet shaft, so door frame can swing or even twist when using, and causes the chamber door closure to take place less than situation such as put in place, therefore will transform existing chamber door hinge technology.
The utility model content
The purpose of the utility model is to the existing defective of existing known technology product, provides a kind of and has simple in structurely, easy for installation, and cost of production is low, wear of hinge property, long service life, the wear-resisting type chamber door hinge that folding is stable.
The purpose of the utility model is achieved in that a kind of wear-resisting type chamber door hinge; Comprise base plate and door frame by the first hinge active link; Also pull bar is arranged on the base plate through the 3rd hinge hinges; It is characterized in that: described pull bar top is movably hinged with roller through second hinge, and roller can freely rotate on second hinge axis, and roller places the interior slip of the chute of door frame.
Described door frame is provided with axle sleeve, and axle sleeve is enclosed within on the hinge axis of first hinge and rotates, side contacts in axle sleeve both ends of the surface and the mount holder.
Be provided with axle sleeve on the described pull bar equally, axle sleeve is enclosed within on the triple hinged hinge axis and rotates, side contacts in axle sleeve two ends and the mount holder.
Described roller is a sheave.
The roller that is provided with foremost of described chute is installed circular hole, and Circularhole diameter is greater than roller maximum size.
The beneficial effect of the utility model is: 1) have simple in structure, easy for installation, the advantage that cost of production is low.2) door frame is connected through axle sleeve with base plate with pull bar, and axle sleeve is enclosed within on the jointed shaft, effectively increases contact area, reduces local pressure, prolongs hinge application life thereby improve abrasion resistance.3) the axle sleeve two ends withstand on the medial surface of support, and limit has been put about it and jumped, and have avoided door frame to rock or even twist.4) the pull bar top is provided with roller rotational slip in the chute of door frame, reduces frictional force, further increases the service life.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to explain.As shown in the figure: a kind of wear-resisting type chamber door hinge; Comprise base plate 6 and door frame 5 by first hinge, 1 active link; Also pull bar 7 is arranged on the base plate 6 through the 3rd hinge 3 hinges; It is characterized in that: described pull bar 7 tops are movably hinged with roller 4 through second hinge 2, and roller 4 can freely rotate on second hinge axis, and roller 4 places chute 51 interior slips of door frame 5.
Described door frame 5 is provided with axle sleeve 8, and axle sleeve 8 is enclosed within on the hinge axis of first hinge 1 and rotates, side contacts in axle sleeve both ends of the surface and the mount holder 61.
Be provided with axle sleeve 8 equally on the described pull bar 7, axle sleeve 8 is enclosed within on the hinge axis of the 3rd hinge 3 and rotates, side contacts in axle sleeve 8 two ends and the mount holder 61.
Described roller 4 is a sheave.
The roller that is provided with foremost of described chute 51 is installed circular hole 52, and Circularhole diameter is greater than roller 4 maximum sizes.
Operating principle: in the utility model, first hinge 1 and the 3rd hinge 3 places have all used axle sleeve 8 to be enclosed within on the jointed shaft and have rotated, because axle sleeve 8 length are longer; Its two ends withstand on mount holder 61 inboards; Therefore axle sleeve and jointed shaft contact area are bigger, and when folding was stressed, the jointed shaft large tracts of land was stressed; Reduce local pressure, improve the abrasion resistance of hinge.The axle sleeve two ends withstand on mount holder 61 inboards simultaneously, and limit has put pull bar and door frame jumps about on the hinge, has avoided door frame to rock or even twist, and improves its job stability.Be provided with roller pull bar top in second hinged place in addition and be provided with rotational slip in the chute of roller at door frame, changing slides is the rotational motion mode.Avoided in the conventional art, used the directly motion mode of sliding friction in chute of rivet, further prolonged its application life.Therefore the utlity model has simple in structurely, easy for installation, cost of production is low, and abrasion resistance is strong, and advantages such as long service life are fit to extensively promote the use of.
