Abstract

The utility model relates to the improvement of a ground hinge. The utility model comprises a cylindrical ground hinge with small volume which is composed of an upper cover, a shaft body, a spring, a base, etc. The shaft body and the spring are arranged in a sealed space which is formed between the upper cover and the base, and working oil is filled in the sealed space in the upper cover and the base. A square shaft part is arranged on the upper end of the shaft body, the square shaft part extends upwards to be inserted into the square hole of the lug of the frame of a door to generate elasticity which can rotate in positive direction and in reverse direction under the acting force of the spring between the frame of the door and the base. The improved ground hinge can be installed without damaging the building, the ground hinge can be locked by screws to be positioned firmly, and the ground hinge can also enable the plates of the door to have functions that the plates of the door can be opened forwards and the plates of the door can also be opened backwards.

Description

Ground hinge

The utility model system is relevant a kind of through the ground of improvement design hinge, integral body slightly becomes a small size cylinder, need not to destroy building when mounted, and need only utilize that screw is sealed can strong fix, and door-plate is had positive and negatively two open function, and have novelty and practical effect.

Being seen ground hinge in the past all is to be installed on the corresponding position, top and bottom of corner end and doorframe behind the door-plate top and bottom, makes the door-plate location that is pivoted, and makes door-plate have able to turn on or off function.

Volume is big because assembly is numerous and diverse for this traditional ground hinge, and is comparatively time-consuming bothersome in the manufacturing assembling, makes manufacturing cost comparatively high, because its volume is big, the restriction that is subjected to installing space often is installed again, the also feasible comparatively difficulty of installing.

Another disappearance is, traditional ground hinge must destroy the surface of building (or doorframe) when installing and fixing, again ground, the wall of building are done to repair the work that beautifies after installing, thereby in the construction of installing, also seem comparatively complicated, waste man-hour and do not conform to economic and practical.

This creator amasss many years of experience, designs a kind of ground hinge through improvement, and integral body slightly becomes a small size cylinder, need not to destroy building when mounted, and need only utilize that screw is sealed can strong fix, and door-plate is had positive and negatively twoly open function, and has novelty.

Main purpose of the present utility model is to improve traditional disappearance, with easy modular construction, the volume of ground hinge is significantly dwindled, and makes and makes and install more and simplify, and have practical effect.

With a cooperation diagram, describe the utility model one specific embodiment in detail as described later: illustrate:

First figure is a stereo appearance figure of the present utility model.

Second figure is an assembly exploded view of the present utility model.

The 3rd figure is a cut away view of the present utility model.

The 4th figure, five figure are respectively action diagram of the present utility model.

The figure number explanation:

10 door frames, 11 fixing threaded holes

12 lugs, 13 square holes

20 loam cakes, 21 axis holes

30 axis bodies, 31 axle bumper portions

32 square shaft sections, 33 circular shaft sections

34 lower shafts, 35 baffle plates

40 springs, 41,42 spring outer ends

50 bases, 51 jack-posts

52 axis holes, 53 outer walls

54,55 baffle plates

As back the utility model shown in the drawings, through the ground hinge of improvement, whole system comprises that institute combines by assemblies such as loam cake 20, axis body 30, spring 40 and bases 50.

The ground hinge of this device is to be connected this door frame 10 with door-plate by a door frame 10, be included in the extended lug 12 of support body one side, this lug is provided with square hole 13, in order to sheathed hinge square shaft, be provided with most fixing threaded holes 11 on this door frame 10 in addition, in order to this door frame 10 is fixed in door-plate.

Loam cake 20 slightly is a circular lid that Open Side Down, becomes one in order to be covered on base 50 and (presses, loam cake 20 has been dissectd some among second figure, so that show clearlyer), the shaft core position of loam cake 20, be provided with a circular axis hole 21, use for wearing axis body 30.

Axis body 30 is to comprise by upper end square shaft section 32, the lower shaft 34 of middle circle shaft part 33 and bottom, the diameter of axle of this lower shaft 34 is less than middle circle shaft part 33, in the axis hole 52 that is inserted in base 50, in addition on the axis body between this middle circle shaft part 33 and the lower shaft 34, Open Side Down to stretch out one, and be the axle bumper portion 31 of 3/4 circle, the outside of this axle bumper portion 31 stretches out a baffle plate 35(as the 4th, baffle plate 35 shown in the five figure figure), in order to only to be butted on the outer wall 53 of base and to remain in coaxial state at combination this baffle plate 35 in season, and because of axle bumper portion 31 between lower open end and lower shaft 34, form one in order to install the space of spring 40.

Spring 40 is one to be the torque spring of coaxial coiling by elastic metallic, two

outer ends

41,42 of spring 40 stretch out respectively, has elastic acting force between this two

outer end

41,42 and make, when this spring 40 is installed in the axle bumper portion 31 of axis body 30, just can only be butted on the both sides of 1/4 breach of axle bumper portion 31 on the axis body 30 respectively by two

outer ends

41,42 of spring 40.

Base 50 is the circular pedestal that slightly becomes an opening to make progress, be provided with jack-post 51 in the position in its axle center, the center of jack-post 51 is provided with axis hole 52, and base 50 circular outsides extend upward partly, form the outer wall 53 of base 50, in addition in the medial surface of this outer wall 53, extend

baffle plate

54,55, two

baffle plates

54,55 to axis direction, just corresponding with axle bumper portion 31 breach of axis body 30, be that 1/4 circular shaft angle is provided with, but and and jack-post 51 between keep an ammunition feed spring 40 to put the gap.

Aforesaid ground hinge, respectively during this combination of components, this axis body 30 and spring 40 are to be located at formed seal cavity inside between loam cake 20 and the base 50, and in the seal cavity of loam cake 20 and base 50 inside filling operation oil; Axis body 30 upper end square shaft sections 32 can supply to be interspersed in square hole 13 inside of door frame lug 12 through loam cake axis hole 21, again, spring 40 in the sealing space, its two

outer end

41,42 be 1/4 breach that only is butted on axle bumper portion 31 on the axis body 30 respectively, with base 50 in the both sides of two

baffle plates

54,55 of correspondence positions, as shown in the 4th figure, therefore make axis body 30(comprise door frame 10) and pedestal 50(comprise loam cake 20) between, but this spring 40 of mat and elastic acting force with a forward and backward.

Therefore, the utility model as implied above, through the ground hinge of improvement, black box is few, constructs simple and easy firm not fragile, the cylinder of small size helps packing, the transportation of finished product and installs, needn't destroy building when mounted, need only utilize that screw is sealed can strong fix, and makes door-plate have positive and negative two function of opening, reach the purpose of aforementioned improvement, and be to close in fact in novelty and the novel creation of ground hinge with effect enhancement.
