Abstract
The utility model discloses a pressure adding buffer device for a vacuum packer chamber cap, which comprises a vacuum chamber cover; the vacuum chamber is connected with a left and a right rocking arm in a rotatable way; the left and the right rocking arm are connected with a flat plate in a rotatable way through a left and a right connection shaft; the left and the right connection shaft are sleeved over the left and the right rocking arm respectively; the left and the right rocking arm are connected with a left and a right oscillating bearing respectively; a spring is set between the left and the right oscillating bearing; the spring is set inside the flat plate. The utility model is provided with reasonable structure, adopting a spring inside the flat plate, separating with the machine frame, increasing space of the frame; the cover keeps stable force in each angle in the process of swing while adding pressure, and the force on the axis is uniform.
Description
Technical field:
The utility model relates to a kind of vacuum packing machine chamber cap pressure-raising shock absorber.
Background technology:
The chamber cap pressure-raising shock absorber that existing vacuum packing machine uses can be divided three classes, one class be the point of action with spring be installed on the frame with swing arm on the upright position, second class is installed in the action of the spring point on the frame equally, but the position is inclined to one side slightly, and the 3rd class is that the action of the spring point is installed in dull and stereotyped both sides.Above version, spring take the space of frame, and the work effect is undesirable.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the vacuum packing machine chamber cap pressure-raising shock absorber of good working effect.
Technical solution of the present utility model is:
A kind of vacuum packing machine chamber cap pressure-raising shock absorber, it is characterized in that: comprise the vacuum chamber lid, the vacuum chamber lid is connected turnably with left and right rocking arm, left and right rocking arm is connected with dull and stereotyped by left and right adapter shaft respectively turnably, be set with left and right swing arm on the left and right adapter shaft, left and right swing arm is connected with left and right oscillating bearing respectively, and shock mount between the left and right oscillating bearing, spring are arranged on dull and stereotyped inner.
The vacuum chamber lid is connected by the zanjon bearing turnably with left and right rocking arm.
One is malleation shape oscillating bearing in the left and right oscillating bearing, and another is anti-thread form oscillating bearing.
The utility model is rational in infrastructure, adopts dull and stereotyped inner mounting spring structure, separates with frame, has increased the space of frame, and lid is in the pressure-raising swing process, and stablizing of all angles confining force, and axle is stressed even.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the readiness for action configuration diagram of an embodiment of the utility model.
Fig. 2 is Fig. 1 embodiment swing state figure.
Fig. 3 is Fig. 1 embodiment vacuum state figure.
Fig. 4 is a constitution diagram after Fig. 1 embodiment exhaust.
The specific embodiment:
A kind of vacuum packing machine chamber cap pressure-raising shock absorber, comprise band handle 1 vacuum chamber lid 2, the vacuum chamber lid is connected by zanjon bearing 10 turnably with left and right Rocker arm 4, left and right rocking arm is connected with dull and stereotyped 3 turnably by left and right adapter shaft 9 respectively, be set with left and right swing arm 5 on the left and right adapter shaft, left and right swing arm is connected with left and right oscillating bearing 8,7 respectively, and shock mount 6 between the left and right oscillating bearing, and spring 6 is arranged on dull and stereotyped 3 inside.Right oscillating bearing 7 is a malleation shape oscillating bearing, and left oscillating bearing 8 is anti-thread form oscillating bearing in addition.
Principle of work of the present utility model is:
When readiness for action, spring 6 overcomes lid (vacuum chamber lid) 2 the gravity and the damping of each point of connection, and each parts of system are in stabilized conditions, changes pulling force, the elemental height that decision lid 2 is upspring by rotating regulating spring 6.
When swing state, by the external force effect, lid 2 rotates by left-hand is middle under the constraint of axle 9, swing arm becomes 90 ° by 147 °, lid 2 gravity are more and more littler to the influence of spring, lid 2 gravity lose the effect to spring in the time of 90 °, and by the tension of spring 6, lid can be stabilized in 90 ° position.
Under vacuum state, by the external force effect, lid under the constraint of axle 9 by middle turning clockwise, become 20 ° up to swing arm 5 by 90 °, the stretching total length of spring becomes 480mm by 440mm, application force to swing arm is in maximum rating, for lid after the vacuum exhaust 2 branch of upspringing automatically takes off electrical equipment control and prepares.
Under state after the exhaust, after the vacuum exhaust, because the pulling force of spring 6 is greater than the influence of lid gravity and each connecting portion damping, lid is upspring automatically, and divides and take off electrical equipment control, spring shortens to 470mm by 480mm, pulling force and gravity is balance progressively, and lid is static, then under external force, remake counter motion, return to readiness for action.
