Description

Pivot offset type rotating door

The technical field is as follows: the utility model relates to a pivot door.

Background art: the door leaf of the common door is hung on the hinge of the side door frame, the weight is also borne by the hinge, and the door leaf is easy to incline and drop when the common door is used for a long time or pulled by a large force. The door leaf of the novel pivoting door takes the pivot vertically arranged at the upper part and the lower part of the door frame as a rotating center, the weight is completely supported by the lower part, and the door leaf can not incline and fall down after long-term use. However, because the rotation axis of the pivot is located in the door leaf, that is, in the door opening enclosed by the door frame, after the door leaf is opened, part of the door leaf is necessarily located in the door opening, so that the passing space of the door opening is reduced, and the opening angle of the door leaf is limited, so that the door leaf cannot be opened by 180 degrees as a common rotating door.

The invention content is as follows: to the deficiency of the prior art, the utility model provides an open pivot offset formula revolving door that does not occupy the door opening.

The utility model discloses a door frame and door leaf, door leaf use vertical pivot as rotation center, and the pivot is arranged in the outer side door frame department of door leaf, and the subaerial bearing seat that is fixed with of pivot below, through the cooperation of plane rolling bearing pressure-bearing between pivot lower extreme and the bearing seat, the axle sleeve cup joints the cooperation on the pivot, and one side of door leaf is fixed with the door leaf support, door leaf support and axle sleeve connection.

The utility model discloses an outside the door leaf was arranged in to the axis of rotation of pivot partially, also not in the door opening, the door leaf rotated and can leave the door opening completely after opening, and the angle of opening is unrestricted, can open completely, can not occupy the space of passing through that reduces the door opening. And the weight of the door leaf is transferred to the bearing seat on the ground and is stably supported by the ground, the rotation process is easy and labor-saving, and the door leaf can not incline and fall down after being used for a long time.

The invention is further described with reference to the following figures and examples.

Description of the drawings: fig. 1 is a main schematic view of the embodiment.

Fig. 2 is an enlarged schematic view of a-a section of fig. 1.

Fig. 3 is an enlarged schematic view of a section B-B of fig. 1.

Fig. 4 is a rear partial schematic view of fig. 2.

The specific implementation mode is as follows: as shown in fig. 1 to 4, a door frame 2 is matched with a door leaf 1, the door leaf 1 uses a vertical pivot 3 as a rotation center, the pivot 3 is arranged at the lateral side of the door frame 2 outside the door leaf 1, a bearing seat 4 is fixed on the ground below the pivot 3, and the lower end of the pivot 3 is in pressure-bearing fit with the bearing seat 4 through a plane rotation bearing 5. The shaft sleeve 7 is sleeved on the pivot 3 to be matched, a door leaf support 8 is fixed on one side of the door leaf 1, and the door leaf support 8 is connected with the shaft sleeve 7.

The weight of the door 1 is transmitted to the bearing seat 4 on the ground through the door bracket 8, the shaft sleeve 7, the pivot 3 and the like, and is stably supported by the ground. When the door leaf 1 rotates, the plane rotating bearing 5 can ensure easy and labor-saving rotation in a pressure-bearing state. According to the requirement, the pivot shaft 3 can be sleeved with a rolling bearing, so that the rotation is smoother. In practice, the pivot 3 is generally arranged coaxially in two stages, one above the other and the other below, and does not need to be made as a whole long shaft. The pivot 3 of the upper section is not required to bear weight, and is arranged on the upper section of the side doorframe 2 in a non-bearing way through the connecting frame 13.

The pivot 3 and the shaft sleeve 7 of the embodiment are matched through an axial spline 6, the lower part of the pivot 3 is further sleeved with a hollow screw 9, the periphery of the hollow screw 9 is in threaded connection with an adjusting nut 10, and the upper end of the hollow screw 9 is in contact with the lower end of the shaft sleeve 7 to form an up-and-down adjusting mechanism. Therefore, when the door is installed, the positions of the door frame 2, the pivot 3 and the like can be installed and adjusted, and finally the door leaf 1 is connected with the shaft sleeve 7 through the door leaf support 8. The adjusting nut 10 is screwed, the hollow screw 9 moves up and down, and the shaft sleeve 7 moves up and down along the axial spline 6, namely, the up-down position of the door leaf 1 in the door opening can be adjusted.

In this embodiment, the connection between the shaft sleeve 7 and the door leaf support 8 is a bayonet clearance fit, the side wall of the shaft sleeve 7 is provided with an adjusting hole 11, and an adjusting screw 12 traverses the adjusting hole 11 and is connected with the door leaf support 8 to form a front-back left-right adjusting mechanism. The adjusting screw 12 is screwed to enable the door leaf support 8 to move left and right in the bayonet gap of the shaft sleeve 7, so that the left and right positions of the door leaf 1 in the door opening can be adjusted. After the adjusting screw 12 is loosened, the door leaf bracket 8 together with the adjusting screw 12 can be displaced back and forth in the adjusting hole 11, so that the back and forth position of the door leaf 1 in the door opening can be adjusted.

Additionally, the utility model discloses a door leaf 1 can manual rotation, installs actuating system such as motor additional after, also can regard as electronic revolving door, equally can open completely, can not occupy the space of passing through that reduces the door opening.
