Description of the embodiments

The utility model is described in more detail below with reference to the accompanying drawings. The utility model provides a turn-up type is with stopping hinge, its includes main part 1 and articulates arm 2 of installing above that, articulates on the arm 2 and installs arm-tie 3, and the arm-tie 3 other end passes through extension spring 4 to be connected with main part 1, and extension spring 4 produces pulling force and drives arm-tie 2 all the time to opening direction swing, its characterized in that: the hinge arm is characterized in that the accommodating groove 5 is formed in the main body 1, the sliding groove 6 is formed in the side wall of the accommodating groove 5, the guide wheel 7 is slidably mounted in the sliding groove 6 through the pin shaft 8, the push spring frame 9 is further arranged in the accommodating groove 5, one end of the push spring frame 9 is supported on the pin shaft 8, the other end of the push spring frame is slidably mounted in the positioning frame 10 positioned in the accommodating groove 5, the reset push spring 11 is sleeved on the push spring frame 9, the reset push spring 11 pushes the guide wheel 7 to always move towards the hinge arm 2, the guide surface 12 is arranged on the end face of the hinge arm 2, the guide surface 12 acts on the guide wheel 7 when the hinge arm 2 is opened, and resistance for preventing the hinge arm 2 from being opened is generated.

The guide surface 12 is an arc-shaped sliding surface arranged on the hinge arm 2, and the guide wheel 7 slides on the arc-shaped sliding surface.

The main body 1 is also provided with a guide groove 13, a guide nail 14 is slidably arranged in the guide groove 13, and the guide nail 14 is connected with the tail part of the pull arm 3.

The guide nail 14 is provided with a hanging tension spring 4, and the other end of the tension spring 4 is hung on a limit nail 15 positioned at the tail part of the main body 1.

The positioning frame 10 is a turned edge of the main body 1, which is bent towards the inner direction of the accommodating groove 5, a guide hole is formed in the turned edge, and the push spring frame 9 is inserted into the guide hole 16.

The front end of the push spring frame 9 is provided with a Y fork 17 which is propped against the pin shaft 8 and limits the guide wheel 7 in the Y fork.

Working principle: as shown in fig. 1, when the hinge is used, the hinge arm part is installed with the box door, the main body part is installed for the box body, and when the box door is opened and closed, the hinge point between the hinge arm and the main body is used as a circle center to swing, so that the box door is driven to be opened or closed.

As shown in fig. 4, when the hinge arm is in the open position, the guide surface 12 provided on the hinge arm acts on the guide wheel 7, creating a resistance against the opening of the hinge arm 2. When the hinge is opened to a certain angle, the gravity of the box door can be balanced through the resistance provided by the guide wheel, so that the box door can freely stop in a certain angle. The specific balance angle can be set after the corresponding calculation of the elasticity of the reset push spring through the design of the radian of the guide surface. Such as: the slow closing angle of the hinge is smaller than 30 degrees, and the angle in the balance stage is 30-65 degrees; and when the slow opening angle is larger than 65 degrees. When the hinge moves to a slow closing angle, the gravity exerted by the door on the hinge arm is greater than the tension of the tension spring, so that the door is closed slowly. When the hinge moves to a balance stage angle, the gravity applied by the door on the hinge arm is added with the tension of the tension spring and the resistance provided by the guide wheel to be in a balance state, in the angle, the door can stay in any angle to keep the door in a half-open state, and when the door needs to be opened or closed, manual operation is needed. When the slow opening angle is larger than 65 degrees, the gravity applied by the box door on the hinge arm is larger than the tension of the tension spring, and the box door is opened outwards under the action of the gravity, so that the purpose of automatically opening the box door is realized.

Compared with the prior art, the special counterweight mechanism can realize that the oven door stops at any position under a certain angle, and improves the functionality of the oven, so that the counterweight mechanism can be widely popularized and used.

It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While the obvious variations or modifications which come out from this are within the scope of the claims which are created by the present utility model.
