Abstract
The utility model relates to a durable diaphragm slice which not only has excellent sealing effect, but also can be effectively avoided being damaged. An embedded structure is adopted at the periphery of a sealing surface of the diaphragm slice and a diaphragm liner plate. Bumps in the diaphragm slice are lower than bosses at the middle part of the diaphragm liner plate. The utility model has the advantages that 1, the embedded structure is adopted at the periphery of the sealing surface of the diaphragm slice and the diaphragm liner plate, so that the sealing performance is good; and 2, the bumps in the diaphragm slice are lower than the bosses at the middle part of the diaphragm liner plate, so that the durable diaphragm slice cannot be squeezed repeatedly in the using process so as to effectively avoid being damaged.
Description
Technical field
The utility model relates to a kind of excellent sealing effect that both had, and a kind of durable type diaphragm that can avoid diaphragm to damage again effectively belongs to diaphragm and makes the field.
Background technology
Existing diaphragm plate is on structural design, because the thickness difference that barrier film liner plate sealing surface and salient point processing produce is bigger, under the oil cylinder impaction state, the diaphragm salient point is in impaction state always, the diaphragm salient point is for a long time, be subjected under the high pressure squeezed state repeatedly, the sheet rubber distortion of diaphragm salient point part is and damaged, and the one-tenth diaphragm reduces service life greatly.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of excellent sealing effect that both had, a kind of durable type diaphragm that can avoid diaphragm to damage again effectively.
Design: in order to realize above-mentioned purpose of design.Adopt damascene structures around diaphragm and the barrier film liner plate sealing surface, the diaphragm boss embeds in the barrier film liner plate by filler rod and the thrust by oil cylinder embeds in the barrier film liner plate caulking groove diaphragm, plays sealing effectiveness.The salient point of barrier film liner plate and sealing surface are same datum level, and its diaphragm salient point adopts filler rod middle saturating empty, can in use not push repeatedly and breakage.
Technical scheme: adopt damascene structures, the salient point in the described diaphragm to be lower than the boss at barrier film liner plate middle part around a kind of durable type diaphragm, diaphragm and barrier film liner plate sealing surface.
The utility model is compared with background technology, and the one, adopt damascene structures, good airproof performance around diaphragm and the barrier film liner plate sealing surface; The 2nd, the salient point in the diaphragm is lower than the boss in the barrier film liner plate, can in use not push repeatedly, avoids diaphragm to damage effectively.
Description of drawings
Fig. 1 is the main TV structure schematic diagram that a kind of durable type diaphragm and barrier film liner plate constitute.
Fig. 2 is the side-looking sectional structure schematic diagram of Fig. 1.
The specific embodiment
Embodiment 1: with reference to attached Fig. 1 and 2.Adopt damascene structures around a kind of durable type diaphragm, diaphragm 2 and barrier film liner plate 1 sealing surface, the thrust by oil cylinder embeds in the barrier film liner plate caulking groove diaphragm, plays sealing effectiveness.Salient point 3 in the described diaphragm 2 is lower than the boss 4 at barrier film liner plate 1 middle part.Described diaphragm 2 boss embed in the barrier film liner plate 1 by filler rod.Described diaphragm salient point adopts filler rod middle saturating empty, can in use not push repeatedly and breakage.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
Claims (3)
1. a durable type diaphragm adopts damascene structures around diaphragm and the barrier film liner plate sealing surface, it is characterized in that: the salient point in the described diaphragm is lower than the boss at barrier film liner plate middle part.
2. durable type diaphragm according to claim 1 is characterized in that: described diaphragm boss embeds in the barrier film liner plate by filler rod.
3. durable type diaphragm according to claim 1 is characterized in that: described diaphragm salient point adopts filler rod middle saturating empty.
