Through user interface circuit, wireless access box is connected to telephone. The method includes following steps: (1) wireless access box receives number of incoming call from network; (2) after receiving number of incoming call, wireless access box sends out DTMF display data of incoming call according to DTMF protocol first, then sends out first ringing sound; after first ringing sound, sends out FSK display data of incoming call according to FSK protocol and subsequent ringing. The invention solves issue that incoming call display cannot be recognized caused by different telephone systems. Using full automatic recognition mode, the invention realizes compatible of DTMF / FSK systems. Wireless access box is not restricted by external phone sets.

The invention relates to a manufacturing method of the detachable fixing part of an elevator protective door. The elevator protective door comprises the fixing part and a rotating part, wherein the fixing part is composed of a left semicircular hoop, a right semicircular hoop, a rotating shaft and a bayonet connecting bolt, the left semicircular hoop and the right semicircular hoop are equal in height and diameter, one end of the left semicircular hoop and one end of the right semicircular hoop are connected with the rotating shaft, the other end of the left semicircular hoop and the other end of the right semicircular hoop respectively bend outwards to form a connecting plate, a U type groove is formed in the middle close to the top of the left connecting plate, a connecting hole corresponding to the U type groove is formed in the center of the right connecting plate, and the bayonet connecting bolt is sequentially inserted in the connecting hole through the U type groove and fastened through a nut to form fastening connection with a stand column. The rotating part is composed of a sleeve and an insertion, the insertion is composed of an inserting section and a protective door connecting section, the sleeve is welded to the outer side face in the middle of the left semicircular hoop, the inserting section of the insertion is inserted into the sleeve and can rotate freely, and the protective door connecting section is connected with a frame of the protective door in a welded mode. The detachable fixing part has the advantage of being convenient to assemble and disassemble, and can be widely applied to high-rise building construction.

The invention discloses a machine net protection group, which comprises a base plate, a connecting plate, a connecting column, a surrounding plate, a mounting hole, a fixing hole, a fixing plate, a limit plate, a box buckle, a cover plate, a nut, a fixing frame and a locking frame. buckle. The beneficial effects of the present invention are: the base plate of the present invention is fixed with a fixing plate for fixing two base plates, the fixing plate is provided with mounting holes, and there are two mounting holes, and the other mounting holes are both Shaped structure, it is convenient to connect the two base plates together, and the waist-shaped hole can adapt to the passage of objects of different shapes, making the connection more extensive. There are also fixing holes running through the fixing plate, which are used for further fixing of the two base plates. There is a limit plate on the outer surface of one end of the bottom plate, and there are two through holes on the limit plate, which are used to fix the locking structure. The outer surface of the bottom plate is provided with a box buckle. The box buckle is an "S"-shaped structure for The locking structure on the fixed limit, the "S" shape structure can make the fixing more convenient and stable.

The invention relates to electric wire winding equipment, in particular to an electric wire winder, which has a fixed-post structure, can almost adapt to any external direction and is used for tightly connecting bundles of electric wires and statically and stably conducting current. The electric wire winder consists of a base module and a locking hoop module, and comprises dozens of parts such as a retaining post seat, a limiting screw, a spring inner sleeve, an elastic jacking bush, a sliding barrel cap, a sliding barrel, a locking hoop spring and a locking hoop bolt. The defects of single wire winding direction, excessively small wire winding quantity, lead looseness, unstable current conducting performance and the like in a current well-known electric wire winder are overcome, and a unique fixed-post multi-direction electric wire winding device is provided for people. Apart from the function of conducting current among a plurality of strands of electric wires of well-known electric wire winding equipment, the electric wire winder further has the beneficial effects of extensive connection, compact connection, static and stable conduction, wide use and the like. Moreover, the electric wire winder is easy to implement, and is easy to manufacture. A formed product is attractive, elegant, firm and durable, and has a wide market space and high practical value and economical added value.
