Description

The structure of the screw seat on the lifting type folding door is fastened and disassembled.

The present invention relates to a structure of a screw-type fixing and fixing of a pulley block assembly on a lifting type folding door, in particular, a truss seat and a convex fixing seat mounted on an upper end surface of a hanging folding door. And the tension clamping mechanism provided in the center of the convex fixing seat is the only structural body and the screw with the separating and separating mechanism is clamped and engaged with a screw cap, and the assembly is fixed and the rotation is adjusted quickly. Disassemble the screw structure designer.

According to the conventionally-built folding door and upper pulley block, the screw-clip separation structure device with quick-release group has several pre-case structures, as disclosed in the application for approval of patent application No. M445059 (see the first figure) The figure is taken from the fourth picture of the case) and the announcement No. M500805 (please refer to the second picture shown in the second figure), which is the structure of the two previous cases; among them, the screw of the former case No. M445059 (3) The inner end surface of the screw head (30) is provided with a radial concave-concave tooth pattern (31), and the concave-concave tooth pattern (31) and the through-restricted piece (4) have a radial shape at the lower end of the through hole (40) The embossing ridges (41) are engaged with each other under the sag weight, and the fixing seat (6) of the wheel pedestal (1) and the locking fixed position sliding door (C) reaching the pulley seat (B) is embossed by the screw (3) The tooth pattern (31) is engaged with the concave-concave tooth pattern (41) of the vertical rest of the limit piece (4), thereby obtaining the effect of not swaying; and, the screw of the former case No. M445059 (2) The T-shaped nose (20) has a sun-like radial arrangement of concave and convex teeth (21), and the convex teeth of the screw (2) T-shaped nose (20) are arranged in a sun-like shape. 21) ie with thin limit solid Sheet holder (4) of The radially-shaped concave teeth (42) punched by the U-shaped bottom end portion of the U-shaped open channel (40) at the lower end surface of the U-shaped open channel (40) are in mesh with each other to obtain a screw (2) The purpose of positioning is not idling; seeing the structure of the two previous cases, because the screw can not be directly detached, it is necessary to slide out the limit piece and remove the upper pulley block and the screw. Therefore, the assembly method of the assembly is cumbersome. And the difficulty, it is difficult to meet the characteristics of the convenience of the current simple demolition, which is missing;

Therefore, according to the tradition mentioned above, there are still many missing problems in the screw structure device of the two quick-release group. For this reason, the creator has further improved and improved the lack of the patent structure of the previous case. It is only after further researching the improvement of the structure here, and finally finally creating the structure of the screw-type fixing and fixing of the pulley block on the above-mentioned hoisting folding door, which can solve the problem of disassembly and repair in one time. The problem is that, based on the above purposes, the main technical means of the present invention include: a convex fixing seat is arranged in a squat groove, and the convex fixing seat is integrally stamped into a convex seat type by a body, and the central protrusion is The top surface is provided with a circular hole, and the left and right sides of the circular hole are provided with two elliptical holes, and the inner groove is provided with a force clamping mechanism, and the tension clamping mechanism is composed of two left and right clutching slides and sleeves. The compression springs of the left and right outer convex end posts of the cassette sliding piece and the sheets of the two clamping slide pieces abut against the upper end surface of a car-like frame of the lift-like car, and the two card-shaped sliding pieces are respectively riveted toward the upper end surface. Inherent round studs, and one with four rivets The frame and the two clamping slides are riveted in the grooves of the convex fixing seat and the central protrusion, and a square spring groove of the car frame is provided with a compression spring and a compression spring cover having a central top surface and a sun-like shape a convex cover with concave and convex wave ridges, and an inverted screw corresponding to the sun-shaped concave and convex wave ridge on the top surface of the convex cover, the screw screw head is formed into an I-shaped head, and the top surface of the I-shaped head is also manufactured There is a sun-shaped concave and convex wave pattern on the top surface of the convex cover. The sun-shaped concave-convex wave-tooth structure with the meshing shape, the I-shaped screw head of the screw head is clamped to the center of the convex fixing seat which is riveted in the ㄩ-shaped seat-shaped groove of the upper end of the folding door The elastic seat of the protrusion is installed in the tension clamping mechanism device of the top-opening and returning card, so that the top surface of the convex cover between the left and right card sliding surfaces has a sun-shaped concave-convex wave-tooth pattern and an inverted spiral head-top sun flower shape. The concave and convex wave ridges are in the meshing state, and the double action of the meshing is difficult to rotate and the rotation is easy to be adjusted, thereby obtaining the function structure of quickly clamping and loosening the screw head; after implementing the above technical means, the following can be obtained Item function: 1. The top surface of the screw I-shaped sun-shaped concave-convex wave-toothed pattern is inverted and fixed on the sun-shaped concave-convex wave-tooth pattern on the top surface of the convex cover. The teeth are meshed with the teeth and the tension clamping mechanism is used. The clamping slide with the clutch and the click and the top spring of the compression spring at the lower end of the convex cover can not only achieve the dual functions of the clamping and the screwing adjustment pitch, but also achieve the rapid assembly or disassembly or adjustment of the pulley block. The function of the whole folding door spacing; 2. The elastic clamping mechanism installed in the convex fixing seat and the tension clamping mechanism of the top cover and the convex cover on the center are like sun-shaped concave and convex waves The tooth pattern is open and open, and can be directly entangled with the concave and convex wave ridges of the sun-shaped end of the I-shaped head of the inverted screw screw head, or the two card slabs are opened and separated. The purpose of the quick disassembly and assembly function; 3. Because the screw is inverted and inserted into the convex fixing seat, the tension clamping mechanism of the elastic self-topping and returning card is installed, and the convex cover at the center is the top surface The sun-like concave-convex wave-tooth pattern is oppositely engaged. Therefore, the inverted-type screw separates the two clamping slides of the tension clamping mechanism directly from the vertical vertical shedding, and the screw-disengagement method is convenient and fast, and thus is quickly disassembled. The purpose of the effect.

According to the above, there is a structure of the screw-engagement fixing of the pulley block on the above-mentioned hanging type folding folding door, which can reach the sun-shaped concave-convex wave tooth of the top surface of the screw type The sun-shaped concave-convex wave-toothed pattern on the top surface of the convex and convex cover is used for the purpose of quick disassembly or device adjustment or spacing adjustment. The technical means and structural features thereof are adopted, and a feasible embodiment is attached.
