Description

Anti-pinch sealing strip for sliding plug door Technical Field The utility model relates to the technical field of sealing strips, in particular to an anti-pinch sealing strip for a sliding plug door. Background The sliding plug door has good sealing performance, can reduce the energy consumption of a passenger room air conditioner, has good shielding effect on rainwater and dust, and has the function of clamping prevention in the moving process of the sliding plug door leaf, so that the sliding plug door is widely applied to rail trains and buses. The existing anti-pinch adhesive tape adopts a unilateral anti-pinch structure, namely one side is provided with an anti-pinch sensing strip, the anti-pinch sensing strip is connected with a program control box through a wire harness, and contacts with the adhesive tape on the other side (without the anti-pinch sensing strip) after encountering an obstacle in the door leaf movement process, so that an anti-pinch signal is sent, and the sliding plug door is opened in time to avoid clamping passengers. However, the structure has the defects of slow induction and imperfect functions in use, and if the obstacle directly contacts one side of the non-anti-pinch induction strip or the single-side anti-pinch structure fails, the anti-pinch function cannot be realized in time. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model provides an anti-pinch sealing strip for a sliding plug door The anti-pinch sealing strip for the sliding plug door comprises a first connecting frame and a second connecting frame, wherein one side of the first connecting frame is fixedly connected with a groove part, one side of the second connecting frame is fixedly connected with a protruding part, mounting grooves are formed in the first connecting frame and the second connecting frame, an anti-pinch device is fixedly connected to the inside of each mounting groove, the anti-pinch device comprises a rubber sleeve, one side of the inside of the rubber sleeve is fixedly connected with a first mounting block, the other side of the inside of the rubber sleeve is fixedly connected with a second mounting block, the first mounting block is connected with a first electrode, the second mounting block is connected with a second electrode, and an elastic strip is fixedly connected to the inside of the rubber sleeve. The number of the elastic strips is two, the elastic strips are respectively arranged on two sides of the inner portion of the rubber sleeve, the elastic strips are silicon rubber elastic bodies, and hollow cavity portions are arranged in the silicon rubber elastic bodies. And inclined plate parts are arranged on the first connecting frame and the second connecting frame, and thick plates are fixedly connected inside the first connecting frame and the second connecting frame respectively. The lower part fixedly connected with of adding the thick plate bends the cardboard, the quantity of bending the cardboard sets up to two. The integrated into one piece has the portion of rising on the first installation piece, set up the standing groove on the portion of rising, first electrode sets up the inside at the standing groove, it has first wire to run through on the portion of rising, first wire and first electrode electric connection. And the second mounting block is penetrated through and fixedly connected with a second lead, and the second lead is electrically connected with a second electrode. Compared with the prior art, the utility model has the beneficial effects that the two sides of the rubber sleeve are provided with the cavity parts containing the silicon rubber elastomer, and the first electrode and the second electrode are respectively integrated to form an independent circuit path. The first connecting frame and the second connecting frame are respectively provided with an independent anti-clamping device, and even if the single-side device fails, the other side can still normally respond to the obstacle. When any side is extruded, the corresponding electrode is contacted and conducted, an anti-pinch signal is triggered, and full circumferential anti-pinch coverage is realized through symmetrical layout of the double-side elastic strips and the electrodes. When the barrier contacts the adhesive tape at any side, the cavity silicon rubber elastomer deforms to enable the electrode to be conducted, so that the problem that the single-side structure fails at the non-induction side is solved. For example, when the arms of a passenger touch two sides of a door leaf at the same time, the electrodes on two sides can be triggered synchronously, so that the detection omission risk caused by single-side triggering in the prior art is avoided. Through modularized design, the rubber sleeve can be independently replaced, so that the maintenance cost is reduced Drawings In order to more clearly illustrate the embodiments of the present utility model or the
