Description
Technical Field
The utility model relates to a joint strip especially relates to an initiative joint strip that sanitation was equipped.
Background
At present, sealing rubber strips on domestic environmental sanitation equipment adopt a pure mode of passively deforming and sealing by means of rubber under pressure. In the working mode, when the flatness of the sealing surface is not good, the rubber is easily pressed too much at the convex part and is locally fractured, a gap is formed at the concave part, and sewage leaks outwards; meanwhile, for compression equipment with a garbage compression function, such as a garbage compression box and the like, when garbage is compressed, the rear door can be subjected to dozens of tons of outward thrust, so that the rear door can deform by several millimeters when being compressed, after the garbage is fully compressed, the garbage still has several tons of thrust on the rear door, the deformation of the rear door still exists, a gap is formed in the sealing surface of the rear door, so that sewage leaks, and secondary pollution can be formed in garbage transfer; with the development of cities, the requirement for controlling the secondary pollution of the garbage is higher and higher.
Disclosure of Invention
An object of the utility model is to overcome prior art not enough, provide an initiative joint strip that sanitation was equipped.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an initiative joint strip that sanitation was equipped, its includes the joint strip main part, the inside of joint strip main part is equipped with the seal chamber, and the seal chamber is connected with the charging connector, and it has compressed air to fill through the charging connector in the seal chamber.
The sealing rubber strip main body comprises an outer rubber layer and an inner rubber layer.
And a reinforcing layer is arranged between the outer rubber layer and the inner rubber layer.
The reinforcing layer is formed by reinforcing cloth.
The utility model adopts the above technical scheme, be equipped with the enhancement layer between outer rubber layer and the inlayer rubber layer, the inside of joint strip main part is equipped with the seal chamber, the seal chamber is connected with the charging connector, fill the air of certain pressure for the inside seal chamber from this charging connector with the ball needle of aerifing, according to the isotropic principle of "PV = constant" and air of compressed air, when the back door is closed, the adhesive tape is provided by inside compressed air to the packing force of sealed face, thereby make the packing force of each point of sealed face department the same, simultaneously according to the principle of "PV = constant", when changing in back door seal clearance, the clearance that the adhesive tape can compensate this change can not change too greatly again to the packing force of sealed face simultaneously, thereby the better special sealed requirement of solving on the sanitation equipment.
Drawings
The invention is described in further detail below with reference to the following figures and embodiments:
fig. 1 is a partial sectional view of a rubber strip used on the existing garbage compression equipment during sealing, wherein each identification symbol in the drawing is as follows: 1 sealed face I, 2 adhesive tapes, 3 sealed face II, 4 gaps.
Fig. 2 is the utility model relates to a sanitation is equipped active joint strip's schematic structure diagram, each sign in the picture: 1 outer rubber layer, 2 reinforced layers, 3 inner rubber layers, 4 inflation nozzles and 5 sealing cavities.
Fig. 3 is a partial sectional view of the adhesive tape of the present invention during sealing, wherein each symbol is as follows: 6 sealed face I, 7 joint strip, 8 sealed face II, 9 seal chamber.
Detailed Description
As shown in figure 1, the sealing rubber strip used on the current environmental sanitation equipment is a partial sectional view during sealing, and as can be seen from figure 1, the rubber strip is easy to have a gap 4 shown in the figure, and sewage is easy to leak out of the gap 4, so that secondary pollution is formed in the garbage transferring process.
As shown in fig. 2, the utility model discloses an initiative joint strip that sanitation was equipped, it includes the joint strip main part, the inside of joint strip main part is equipped with seal chamber 5, and seal chamber 5 is connected with charging connector 4, has compressed air through charging connector 4 packing in the seal chamber 5.
Further, the joint strip body comprises an outer rubber layer 1 and an inner rubber layer 3.
Further, a reinforcing layer 2 is arranged between the outer rubber layer 1 and the inner rubber layer 3.
Further, the reinforcing layer 2 is formed of a reinforcing cloth.
The sealing rubber strip of the utility model is designed according to the principle of PV = constant of compressed air and isotropy of air, as shown in figure 2, the outer rubber layer 1 is used for sealing between two planes needing to be sealed; the reinforcing layer 2 is used for preventing the compressed air from causing the rubber strip to burst when the pressure is too high; the inner rubber layer 3 is used for better sealing cavities in the sealing rubber strips, so that the leakage of compressed air is prevented, and the rubber strips are prevented from bursting due to the separation of the reinforcing layer 2 and the outer rubber layer 1; the inflating nozzle 4 is used for inflating compressed air into the sealing cavity 5 in the sealing rubber strip; the compressed air is used for providing uniform sealing pressing force to the two sealing surfaces from inside to outside for the outer rubber layer 1.
The utility model discloses an initiative joint strip's local section view of sealing work is shown in figure 3, can see out under compressed air pressure P's from inside to outside effect, the adhesive tape can be fine compress tightly the contact with two sealed faces to fine formation is sealed. When two sealed face clearances change simultaneously, the utility model discloses a joint strip can be equipped with the better clearance of this change of compensation of the sealed strip of using under the effect of internal pressure P than present sanitation, can not change too greatly simultaneously to the packing force of sealed face to the special sealed requirement on the better solution sanitation equipment.
