The utility model discloses a bakelite framework convenient to installation relates to bakelite framework technical field, the utility model discloses a framework main part, and the both sides of framework main part top are provided with roof, slot and clamping strip, and the inside of slot is provided with pin, and the outer surface of roof is penetrated with bolt, and the bottom of roof is set up respectively and is limited to the slot and the clamping groove. The utility model discloses a pin, slot, roof, limiting slot and the setting of bolt, when the pin breaks, the bolt is taken off and ends the limiting of roof, after that, the roof is taken off and ends the limiting of pin, at this moment, the pin can be extracted and replaced by going up, when installing, from top to bottom, make the pin pass through the slot, because the pin top end diameter is bigger, thereby avoiding the pin to fall down, after that, the roof is installed back, avoids the roof and the pin from colliding through the limiting slot, and avoids the pin to fall up, after that, the bolt is installed back and is tightened and completes the replacement work, convenient to install the new pin after the pin breaks, thereby better repair effect is realized.

The utility model relates to the technical field of reinforcement cage binding structures, in particular to an assembly type T-beam web steel bar mounting and positioning jig frame. Comprising a supporting frame, a frame connecting clamp, a transverse clamp, a vertical rib positioning assembly and a longitudinal rib positioning assembly. The supporting frames are arranged at intervals in the longitudinal direction, and a plurality of transverse inserting holes are formed in the supporting frames at intervals in the vertical direction. The frame connecting clamps are fixedly arranged on the supporting frames and used for being connected with the connecting longitudinal beams of the adjacent supporting frames in a clamped mode. The transverse clamps are fixedly arranged on the supporting frame at intervals in the vertical direction, each transverse clamp comprises a transverse outer pipe and an adjusting fixing piece, and the adjusting fixing pieces are used for being matched with the transverse outer pipes to be connected with the vertical rib positioning assemblies in a clamped mode; one end of the vertical rib positioning assembly is transversely and slidably sleeved with the transverse outer pipe, and a plurality of positioning grooves are formed in the longitudinal direction at intervals. The longitudinal bar positioning assemblies are transversely inserted into the transverse insertion holes and used for bearing the longitudinal steel bars. The overall structure is simple, the modular design is adopted, flexible disassembly is facilitated, and the extension amount and the longitudinal length of the positioning jig frame are adjusted.

The utility model discloses a can connect lock core relates to lock core technical field, the utility model discloses a lock shell, ratchet wheel, clutch and two lock cartridges, and the lock shell includes ratchet wheel section, two lock cartridge sections and two lengthening sections, and ratchet wheel section, lock cartridge section and lengthening section all include lock pipe part and connecting part, and the both ends of ratchet wheel section connecting part and the outer end surface of two lengthening section connecting part all are equipped with the inlay entrance of waist shape structure, and all is equipped with the threaded mouth of inlay entrance on ratchet wheel section and lengthening section, and the inner end surface of two lock cartridge sections and the inner end surface of two lengthening sections all are equipped with the inlay block, and is equipped with the through -hole on the inlay block. The utility model discloses a novel lock core mechanism, can realize the standardization production of ratchet wheel section, lock cartridge section, ratchet wheel, clutch and marble mechanism, can realize the production and assembly of different length lock core through the length adjustment of lengthening section, can be applicable to the special application point of non - standardization simultaneously, improves the scope of application, can greatly reduce the cost of lock core.
