Abstract
This utility model relates to a hinge, specifically to a top-end-lubricating fireproof hinge for fireproof door, which comprises two hinge sheets with corresponding hinge shaft sleeves and a hinge shaft, wherein a bearing coaxial with the hinge shaft sleeves and having the same outer diameter as the hinge shaft sleeves is arranged between the hinge shaft sleeves of the two hinge sheets; the hinge shaft is arranged in such a manner of penetrating through the hinge shaft sleeves of the two hinge sheets and the bearing; the top end of the hinge shaft is fixedly connected with hinge shaft caps which are extended out of the hinge shaft sleeves; oil grooves are arranged on the centers of the hinge shaft caps; the bottom parts of the oil grooves are provided with oil holes for adding lubricating oil; according to the structure of the fireproof hinge disclosed by this utility model, the hinge shaft which is arranged outside the hinge shaft sleeves is supported by the bearing, thus the coaxiality of the hinge shaft and the hinge shaft sleeves is further ensured, and the rotating lubricity is improved to prevent excessive friction between the hinge shaft and the hinge shaft sleeves; in addition, the oil grooves are arranged on the top of the hinge shaft additionally, in this way, the friction among the hinge shaft, the hinge shaft sleeves and the bearing is further reduced by adding the lubricating oil, thus, the service life of the hinge is prolonged.
Description
Technical field
The utility model relates to a kind of hinge, relates in particular to a kind of top lubricated type labeled door fire prevention hinge.
Background technology
Labeled door has characteristics such as smooth surface is smooth, elegant in appearance, unlatching is flexible, sturdy and durable, esy to use, safe and reliable, is extensively used as family's entry door.The door body weight of labeled door is greater than the common door body; So there is following shortcoming in the existing hinge of use as the fire prevention hinge of labeled door: the feasible hinge that is arranged in the hinge shaft sleeve of huge pressure tilts and hinge shaft sleeve takes place to rub and two hinge shaft sleeves at hinge plate rub mutually because hinge plate bears; Make a noise when opening; Hinge plate is damaged, and the life-span of this hinge is low.
The utility model content
The utility model technical problem to be solved is, overcomes the deficiency that exists in the prior art, and a kind of hinge friction and prolong the fire prevention hinge that is used for labeled door in hinge life-span of reducing to prevent fires is provided.
The utility model is to be achieved through following technical scheme:
A kind of top lubricated type labeled door fire prevention hinge; Comprise two hinge plate and hinges that have corresponding hinge shaft sleeve; Bearing coaxial with hinge shaft sleeve and that external diameter is identical is set between the hinge shaft sleeve of described two hinge plates, and said hinge runs through the hinge shaft sleeve and the bearing setting of two hinge plates, and said hinge upwards stretches out the hinge shaft sleeve end and is provided with the hinge cap; Said hinge cap center is provided with oil groove, and the oil through that is used to add lubrication oil is offered in said oil groove bottom.
The beneficial effect of the utility model is:
Because bearing coaxial with hinge shaft sleeve and that external diameter is identical is set between the hinge shaft sleeve of two hinge plates, make hinge outside hinge shaft sleeve, obtain the support of bearing again; Further guarantee the alignment of hinge and hinge shaft sleeve, and improve the lubricity of rotating, prevent the excessive friction of hinge and hinge shaft sleeve; In addition; Set up oil groove at the hinge top, the friction between hinge axis and hinge shaft sleeve and the bearing is further reduced through adding lubrication oil, thereby prolonged the application life of hinge.
Description of drawings
Fig. 1 is the main TV structure sketch map of the utility model.
Among the figure: 1. hinge plate, 2. bearing, 3. hinge, 4. hinge shaft sleeve, 5. hinge cap, 6. oil groove, 7. oil through.
The specific embodiment
For the technician who makes the present technique field understands the technical scheme of the utility model better, the utility model is done further to specify below in conjunction with accompanying drawing and most preferred embodiment.
As shown in Figure 1; The utility model comprises two hinge plate 1 and the hinges 3 that have corresponding hinge shaft sleeve; Bearing 2 coaxial with hinge shaft sleeve and that external diameter is identical is set between the hinge shaft sleeve 4 of described two hinge plates 1, and hinge shaft sleeve 4 and bearing 2 that said hinge 3 runs through two hinge plates are provided with, and said hinge 3 upwards stretches out hinge shaft sleeve 4 ends and is provided with hinge cap 5; Said hinge cap center is provided with oil groove 6, and the oil through 7 that is used to add lubrication oil is offered in said oil groove bottom.
Because bearing 2 coaxial with hinge shaft sleeve and that external diameter is identical is set between the hinge shaft sleeve 4 of two hinge plates 1; Make hinge 3 outside hinge shaft sleeve 4, obtain the support of bearing 2 again, further guarantee the alignment of hinge 3 and hinge shaft sleeve 4; And the lubricity of raising rotation; Prevent the excessive friction of hinge 3 and hinge shaft sleeve 4, in addition, set up oil groove 6 at the hinge top; Friction between hinge axis and hinge shaft sleeve 4 and the bearing 2 is further reduced through adding lubrication oil, thereby prolong the application life of hinge.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
