Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

As shown in fig. 1, fig. 2 and fig. 3, the utility model discloses technical scheme a revolving door prevents pressing from both sides door leaf, include with 1 articulated rotatory door leaf 2 of exhibition case, rotatory door leaf 2 is close to 1 side of exhibition case and is provided with hinge mechanisms. The hinging mechanism comprises a first hinging block 11 and a second hinging block 22 fixed with the display case 1 and the rotary door leaf 2, respectively. The first hinging block 11 and the second hinging block 22 are respectively provided with a first shaft hole 13 and a second shaft hole, and the hinging shaft 5 passes through the first shaft hole 13 and the second shaft hole. Exhibition case 1 and rotatory door leaf 2 realize connecting through articulated shaft 5, realize the installation to rotatory door leaf 2, simultaneously behind pressing from both sides the people, promotion rotatory door leaf 2 that can be quick for 2 free ends of rotatory door leaf are close to exhibition case 1, will press from both sides people position and give way, make by the person of pressing from both sides can be rescued.

The articulated shaft 5 between the first articulated block 11 and the second articulated block 22 is sleeved with a torsion spring 4, and the torsion spring 4 keeps the rotary door leaf 2 away from the display box 1 and is in a normal working state. The torsional spring 4 can ensure that the rotary door leaf 2 does not shake or rotate in normal work, and the normal work is ensured.

The bottom of the exhibition box 1 is provided with a supporting seat 12, the supporting seat 12 is arranged at the bottom of the second hinging block 22 on the lowest layer, a concave semicircular groove is arranged on the upper surface of the supporting seat 12, and a hemispheroid 23 arranged in the semicircular groove is arranged at the bottom of the second hinging block 22 on the lowest layer. The semicircular groove and the hemisphere 23 are arranged and installed, so that the rotary door leaf 2 is fixed and supported, and the rotary door leaf 2 is convenient to install and fix. And the hemisphere 23 sets up, has reduced rotatory door leaf 2 and need exert the strength size in the rotation, and the revolving door of being convenient for promotes, is convenient for to be pressed from both sides the person and rescues.

As shown in fig. 2 and 3, the uppermost second hinge block 22 is located above the uppermost first hinge block 11 without a torsion spring therebetween. The first hinge block 11 at the uppermost layer is provided with a first square hole 14, the first square hole 14 is positioned at the upper part of the first shaft hole 13 and is coaxially arranged, and the outer diameter of the first square hole 14 is larger than the diameter of the first shaft hole 13. A second square hole 24 is arranged in the second hinge block 22 at the uppermost layer, and the first square hole 14 and the second square hole 24 are coaxial and have adaptive outer diameters. The limiting pin 6 is arranged in the first square hole 14 and the second square hole 24, and the cross section of the limiting pin 6 is matched with that of the first square hole 14. The top of the limit pin 6 is connected with a pull rope 61, and the outer end of the pull rope 61 extends to the outside of the rotary door leaf 2. Here, the setting of spacer pin, in the revolving door normal work, the spacer pin 6 both ends are located the second articulated piece 22 of the superiors and the first articulated piece 11 of the superiors respectively, lie in first square hole 14 and second square hole 24 respectively promptly, realize that rotatory door leaf 2 carries on spacingly, avoid rotatory door leaf 2 in the revolving door normal work, external force can not directly promote rotatory door leaf 2 and rotate, further ensure rotatory door leaf 2 and revolving door normal work. After the person is clamped, the pull rope 61 is pulled, so that the limit pin 6 is separated from the first hinge block 11, the rotary door leaf 2 can be pushed, and the person to be clamped is conveniently rescued.

As shown in fig. 4 and 5, the length of the stopper pin 6 is smaller than that of the second square hole 24, so that the stopper pin 6 can be completely separated from the first square hole 14 after being pulled upward. The upper opening of the second square hole 24 is provided with a cover plate 25, and the pull rope 61 passes through the cover plate 25. The setting of apron avoids pulling out second quad slit 24 with spacer pin 6, avoids needing to carry out safety to spacer pin 6 after being saved by the clamp person for the operation is inconvenient. In this technique, after the person of being pressed from both sides is rescued, loosen stay cord 61 free end, spacer pin 6 can automatic re-setting get into first square hole 14 and second square hole 24 in, realize limiting displacement.

As shown in fig. 2, a hollow buffer column 21 is disposed on the side of the rotary door leaf 2 away from the display box 1, the pull rope 61 is in a tensioned state, and the outer end (free end) passes through the hollow buffer column 21 and is fixed with the bottom of the hollow buffer column 21. And the pull rope 61 is positioned in the hollow buffer column 21 and is arranged close to the inner side surface of the hollow buffer column 21 far away from the rotary door leaf 2, and the pull rope 61 has no elasticity. The setting of cavity cushion column 21 in this technical scheme utilizes the deformability of cavity cushion column 21 on the one hand, avoids rotatory door leaf 2's glass in the contact of the person of being pressed from both sides, reduces the injury to the person of being pressed from both sides. On the other hand, a mounting and fixing position is provided for the pull rope 61, after people are clamped, the hollow buffer column 21 deforms, the pull rope 61 in the hollow buffer column is compressed and deformed, the pull rope 61 is pulled out upwards to form the limiting pin 6, the limiting pin 6 is separated from the first square hole 14, and at the moment, the rotating door leaf 2 can be pushed to rotate towards the exhibition box 1 side, so that the clamped people can be conveniently rescued. And the setting of cavity core cushion post 21 and the fixed of stay cord 61 are pressed from both sides the back at personnel for pressed from both sides person self and can promote rotatory door leaf 2, and the person pressed from both sides can oneself save promptly, improves the efficiency of saving, and the effectual problem of being pressed from both sides the long-time quilt of avoiding pressed from both sides the person.

In the technical scheme, the limit pin 6 is connected with a second pull rope, and the outer end of the second pull rope penetrates through the cover plate 25 and penetrates through the top of the rotary door leaf 2 and is fixed on the outer side of the rotary door leaf 2. Preferably fixed at a position facing the person outside the rotating door leaf 2 and is easily pulled by the person. This technical scheme's setting, the operating personnel of being convenient for realizes the control to spacer pin 6 by outside pulling second stay cord.

The upper end of the hinge shaft 5 is disposed in the first shaft hole 13 of the uppermost first hinge block 11, and the top of the hinge shaft 5 is coaxially provided with a screw hole 51. The screw hole 51 is provided to facilitate the installation and removal of the hinge shaft 5 by screwing the connecting rod into the screw hole 51.

It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present disclosure.
