The invention discloses a self-locking rocker switch. The switch comprises a switch upper shell, a switch lower shell and a switch cover, a switch cover waterproof, dustproof and moistureproof cap isarranged in the middle of the upper end of the switch upper shell, the switch cover is connected to the switch upper shell through the switch cover waterproof, dustproof and moistureproof cap, one endof the switch lower shell is connected from the bottom of the switch upper shell in an embedded mode, and a switch upper and lower shell waterproof, dustproof and moistureproof pad is arranged between the switch lower shell and the inner side wall of the switch upper shell. Waterproof, dustproof and moistureproof sealing of the switch is achieved when the switch is used in open-air rainy days, the switch is self-locked, the wiring terminal base is prevented from falling off, the service life of the switch is longer, and the switch is more convenient and efficient to use.

The invention belongs to the technical field of safety anti-theft devices, and relates to a lock and a shared bicycle. The lock comprises a shell, a lock rod, an unlocking and holding mechanism, a lock catch and a driving mechanism, wherein a lock opening used for a locked object to be inserted thereinto is formed in the shell, one end of the lock rod is rotationally connected to the shell and islocated on one side of the lock opening, the lock catch is arranged on the shell and is located on the other side of the lock opening. When an unlocking signal is received, the driving mechanism drives the lock catch to move to an unlocking position so as to release locking of the lock rod, and the lock rod is rotated to the unlocking position under the action of gravity. Compared with the prior art, the lock in the embodiment has the advantages that the situation that a tension spring needs to be arranged to return the lock rod is avoided, unlocking and locking are safe and reliable, and theservice life of the lock is prolonged.

The invention discloses a machining tool, particularly a machining tool for blocking wheels of rotary kilns, belongs to the technical field of maintenance and manufacturing of cement production equipment. According to the machining tool for the blocking wheels of the rotary kilns, disassembly of the blocking wheels is not required, and machining can be conducted on the spot. The machining tool comprises a knife rest, an installation frame and an annular section-shaped supporting frame, wherein the installation frame is provided with an adjusting shaft; the annular section-shaped supporting frame is provided with an installation base line; the knife rest is installed on the installation frame in such a way that the knife rest can reciprocate on the adjusting shaft in the axial direction of the adjusting shaft; a hinged shaft is arranged on an inner arc of the annular section-shaped supporting frame; and the installation frame is installed on the annular section-shaped supporting frame in such a way that the installation frame can rotate in a reciprocating manner around the hinged shaft.

An external light-shielding plate for a gas discharge lamp, which includes: an upper reflection part, which is an arc part formed by cutting more than half of a first frustum-shaped cylinder, wherein the corresponding cut part forms a second A notch; the lower reflection part is a special-shaped conical truncated portion formed by cutting less than 1 / 2 of the second truncated conical cylinder, wherein the corresponding cut-off part forms a second gap; the large opening of the second truncated conical cylinder The end is directly connected with the large mouth end of the first frustum-shaped cylinder; the edge of the second notch is directly connected with the edge of the first notch; wherein, the clamp between the generatrix of the first frustum-shaped cylinder and the central axis of the first frustum-shaped cylinder The angle is greater than the included angle between the generatrix of the second frustum-shaped cylinder and the central axis of the second frustum-shaped cylinder. The above-mentioned gas discharge lamp adopts an external shading plate and cancels the built-in shading plate, which can effectively reduce the light emitted by the light source from irradiating the light source, thereby reducing the temperature of the light source and improving the use of the light source. The invention also provides a gas discharge lamp.

The invention discloses a terminal box, which includes a box body and a support seat, the box body is detachably arranged on the support seat, the box body includes a top plate, a bottom plate, a box door and three side plates connected in sequence, and the top plate is arranged on the side plate The top surface, the bottom plate is arranged at the position where the side plate is adjacent to the bottom end surface, and the bottom surface of the bottom plate and the side plate is spaced apart, and the top plate, side plate and bottom plate are surrounded to form a cavity, which is used to accommodate electrical components and connecting wires, and the bottom plate There are wire holes, and the door is rotated on one side of the chamber. Each side board includes an inner board and an outer board. The inner boards are connected in sequence, and the outer boards are correspondingly arranged on the inner board away from the chamber. One side of the side, and the outer board and the inner board are detachably connected through the first connection assembly, the top board and the inner board are detachably connected through the second connection assembly, and the top board extends toward the outside of the box in the horizontal direction, and the electrical components are set The side of the inner board facing away from the outer board. It can replace the top plate and outer plate separately and has a long service life.
