Detailed Description
The following specific examples are intended to be illustrative of the invention and are not intended to be limiting, as modifications of the invention will be apparent to those skilled in the art upon reading the specification without inventive contribution thereto, and are intended to be protected by the patent law within the scope of the appended claims.
The invention relates to a sealing strip, which comprises a main body 1 and an anti-drop ring 2, wherein the anti-drop ring 2 is embedded in the main body 1, and the compression amount of the anti-drop ring 2 is smaller than that of the main body 1; when the main body 1 is compressed, the compression direction is towards the anti-slip ring 2, and the anti-slip ring 2 shares the compression amount of a part of the main body 1, but the compression amount of the anti-slip ring 2 is smaller, so that the main body 1 can be reinforced, and the main body 1 is prevented from being excessively compressed and deformed. When in actual use, the main body 1 is arranged on the suction cup, and when the suction cup adsorbs building materials, the main body 1 can fill up the gap between the suction cup and the building materials, so that the suction cup and the building materials are in a closed state; when the sucker is separated from the building material, the residual negative pressure pulls the main body 1, the main body 1 is compressed under the pulling of the negative pressure, and if the anti-drop ring 2 does not exist, the main body 1 is continuously compressed and deformed until the sucker is separated; under the condition that the anti-drop ring 2 exists, the compression direction faces the anti-drop ring 2, and as the compression is gradually carried out, the compression process of the main body 1 is blocked by the anti-drop ring 2 and cannot continue to compress, so that the problem of drop caused by deformation of the main body 1 is avoided. Therefore, the sealing strip is designed in a split type with the sucker, and can be replaced when damaged, so that the maintenance cost is reduced, the maintenance process is simplified, the back glue is not required to be reinforced in the installation process, and the trouble of removing the back glue in the replacement process is omitted.
Fig. 1 shows a specific structure of the sealing strip 1, the main body 1 includes a sealing portion 11 for sealing the suction cup and the adsorbate (in this specification, the building material component to be adsorbed) and a connecting portion 12 for connecting with the suction cup, the sealing portion 11 is connected with the connecting portion 12, preferably, the two are integrally formed, and a containing groove 121 for containing the anti-drop ring 2 is formed in the connecting portion 12. Since the body 1 and the suction cup are separated from each other by the compression deformation of the sealing portion 11 and the connecting portion 12, but the body 1 and the suction cup are separated from each other mainly by the compression deformation of the connecting portion 12, the accommodating groove 121 is formed in the connecting portion 12, and the retaining ring 2 is disposed in the accommodating groove 121 to strengthen the connecting portion 12 of the body 1 and prevent the retaining ring from separating from the suction cup.
In this embodiment, the connecting portion 12 is preferably trapezoidal, and the width of the connecting portion 12 gradually increases from the sealing portion 11 toward a direction away from the sealing portion 11, so that when the main body 1 is mounted on the suction cup, the width of a portion of the connecting portion 12 closer to the suction cup is larger, and the connection between the connecting portion 12 and the suction cup is firmer. Further, the receiving groove 121 is provided near the end of the connecting portion 12 having a larger width, further ensuring that when the connecting portion 12 is compressed, the compression direction is directed to the receiving groove 121, so that the anti-slip ring 2 hinders the continued compression of the main body 1. The sealing portion 11 is provided with the mounting channel 111, and the mounting channel 111 penetrates from the surface of the sealing portion 11 to the accommodating groove 121, as shown in fig. 1, the mounting channel 111 may be only a gap connecting the surface of the sealing portion 11 and the accommodating groove 121, because the main body 1 is a soft material capable of being compressed, the main body 1 can be easily plugged into the accommodating groove 121 from the mounting channel 111 when the anti-drop ring 2 is arranged, and meanwhile, the whole structure of the main body 1 is relatively complete, so that the main effect of the main body 1 is ensured not to be weakened due to the existence of the mounting channel 111. Wherein, the main body 1 can be made of foaming material, and the anti-drop ring 2 is made of rubber material with smaller compression than the main body 1.
The junction between sealing portion 11 and connecting portion 12 is provided with arc draw-in groove 112, and the quantity of draw-in groove 112 is two, and two draw-in grooves 112 set up in the both sides of sealing portion 11 respectively. When in actual use, the suction cup is provided with a trapezoid groove corresponding to the connecting part 12, and the connecting part 12 is embedded into the groove on the suction cup to complete the connection of the sealing strip and the suction cup. The sealing part 11 protrudes out of the suction cup at this time. The drop-off prevention ring 2 is inserted into the receiving groove 121 through the mounting passage 111. When the sucking disc adsorbs the building materials, sealing portion 11 laminating mutually and take place the deformation of certain degree with the surface of building materials to pack the clearance between sucking disc and the building materials, make between sucking disc and the building materials be sealed state, and then make the sucking disc can normally adsorb the building materials. When the sucking disc breaks away from the building material, the main body 1 is pulled by the residual negative pressure between the sucking disc and the building material, so that the main body 1 deforms to a certain extent, and the deformation direction of the main body 1 is guided under the influence of the shape of the connecting portion 12 and the position where the accommodating groove 121 is arranged, so that the deformation of the main body 1 is in a compression state pointing to the anti-dropping ring 2 at the connecting position between the sealing portion 11 and the connecting portion 12. Because the compression amount of the anti-drop ring 2 is smaller than the compression amount of the main body 1, when the compression process of the main body 1 is performed to a certain extent, the anti-drop ring 2 prevents the compression process from being further performed, thereby preventing the main body 1 from being further deformed, and further preventing the sealing strip from being separated from the sucker. When the sealing strip needs to be removed, the anti-drop ring 2 can be taken out through the mounting channel 111, and then the main body 1 can be pulled out from the sucker. Wherein, can set up corresponding arch on the inner wall of trapezoidal recess on the sucking disc too, when this sealing strip is connected with the sucking disc, this arch can stretch into in the draw-in groove 112 to when main part 1 takes place deformation, further guide the deformation direction of main part 1. In conclusion, the sealing strip is in a split type design with the sucker, and when the sealing strip is damaged, the sealing strip can be independently replaced, so that the maintenance cost is reduced, and the maintenance process is simplified. Meanwhile, the invention does not need to adopt back glue for reinforcement during installation, so that the residual back glue does not need to be treated during replacement.
The utility model provides a vacuum chuck convenient to maintain, includes a sealing strip as described earlier, still includes the adsorption part 3 that is used for adsorbing the adsorbate, the sealing strip embedding in the adsorption part 3. The adsorption part 3 is provided with a mounting groove 31, and the mounting groove 31 is trapezoidal and is used for accommodating the connecting part 12. The side wall of the mounting groove 31 is provided with a clamping protrusion 311, and the clamping protrusion 311 extends from two sides of the mounting groove 31 to the sealing strip.
In actual use, the connection portion 12 is fitted into the mounting groove 31. At this time, the engaging protrusion 311 corresponds to the engaging groove 112. When the sucking disc breaks away from the building materials, the residual negative pressure pulls the sealing strip. At this time, the clamping protrusion 311 will squeeze the sealing strip, so that the portion where the sealing strip meets the clamping protrusion 311 begins to compress in the direction of the anti-drop ring 2. Because the compression amount of the anti-drop ring 2 is smaller than that of the main body 1, when the anti-drop ring 2 is compressed to a certain extent, the main body 1 is prevented from being compressed continuously, so that the main body 1 is prevented from being deformed continuously, and the sealing strip is prevented from being separated from the sucker. From this, be split type design between sucking disc and the sealing strip, when the sealing strip takes place to damage, can change alone the sealing strip. And the installation of the sealing strip does not need to be reinforced by back glue, so that the trouble of removing the back glue is omitted when the sealing strip is replaced.
