Take damped rotation regulation mechanism

Technical Field

The utility model belongs to the field of supporting structures, and particularly relates to a rotary adjusting structure with damping.

Background

In recent years, the intelligent metering industry is rapidly developed, and particularly, devices such as a flowmeter, a valve controller and the like are increasingly intelligent. The function of the traditional control valve can be met, a series of functions such as data storage, reporting, settlement and feedback can be realized, and the feedback of data such as gas amount and balance is supported by a human-computer interaction system. The traditional man-machine interaction system display is fixed on the base, the angle cannot be adjusted, and great inconvenience is caused to information reading in special occasions. Aiming at the situation, the double-freedom-degree adjustment can be realized by matching the rotating shaft with the damper, and the double-freedom-degree adjustment can be stopped at any position to realize full-angle display. The structure is simple, and can be popularized and applied to various display devices.

Detailed Description

An example of the present invention on a valve controller will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, a rotation adjusting structure with damping is mounted on any controller 1 and base 5 (the base only plays a supporting role), and includes a mounting bracket 2, a rotating bracket 3, a mounting plate 4, a first damper 601 and a second damper 602.

As shown in fig. 3, the mounting plate 4 is provided with a second damper mounting groove 402, and a second damper 602 is fixed by providing a damper mounting threaded hole 401 in the second damper mounting groove 402 to be engaged with a screw; the mounting plate 4 is further provided with a pair of mounting plate fixing threaded holes, which are aligned with a pair of rotating bracket fixing threaded holes 301 formed at one end of the rotating bracket 3 shown in fig. 4, and then are matched with screws to fix the mounting plate 4 and the rotating bracket 3 on the base. The second damper 602 is disposed between the mounting plate 4 and the base 5, and realizes the rotational movement of the mounting plate on the base plane, and maintains the attitude thereof at an arbitrary position by the damper.

A first damper mounting hole 302 is provided at the other end of the rotating bracket 3.

As shown in fig. 5, one end of the mounting bracket 2 is provided with a mounting bracket fixing threaded hole, and the mounting bracket fixing threaded hole is matched with a screw to be fixed on the controller 1; the other end of the mounting bracket 2 is provided with a first damper mounting groove 201, and a first damper 601 is fixed in the first damper mounting groove 201;

in this embodiment, there are two mounting brackets 2, and the first damper mounting grooves 201 of the two mounting brackets 2 are respectively fixed at two ends of the first damper mounting hole 302; the two first dampers 601 are locked between the mounting bracket 2 and the rotating bracket 3 under the cooperation of the two first damper mounting grooves 201 and the first damper mounting holes 302, so that the damping effect and the angle adjustment in the Y-axis direction are realized, and the controller 1 can maintain the angle.

Fig. 6 is a schematic structural view of the damper according to this embodiment.

When the rotary bracket is in work, the rotary bracket 3 can rotate around the Z axis and can be stopped at any position under the action of the damper 602; the controller 1 can rotate around the Y axis and can stop at any angle of 0-180 degrees under the action of the damper 601 and keep the posture. The two rotational degrees of freedom act in combination to enable the controller 1 to face any position and maintain a posture.

As shown in fig. 7, if the controller 1 needs to be adjusted from the horizontal position to the vertical position, the required applied force F satisfies the following formula:

wherein: l is the length of the controller, which can be considered as the distance between the applied force and the damper axis; g is the gravity of the controller, and the gravity center can be regarded as the geometric center of the controller in an ideal state; m is the damper torque.

Taking L as 140mm, G as 1500G, and M as 1 N.m, the following can be obtained:

F≈7.9N

that is, the controller angle can be adjusted by applying about 0.8 kgf.

As shown in fig. 8, when the base 5 is vertically installed together with the rotating bracket 3, the weight G borne by the damper is the smallest in this position. To hold the controller in this position, the gravity G of the controller should satisfy the following formula:

wherein: l is the length of the controller; g is the gravity of the controller, and the gravity center can be regarded as the geometric center of the controller in an ideal state; m is the damper torque.

Taking L as 140mm and M as 1 N.m, the following can be obtained:

G≤14.29N

that is, the controller weight is 14.29N at the maximum, about 1.46kg, with the controller length unchanged.
