Description
Technical Field
The invention relates to a connector between profile frames, in particular to a quick connector without tools.
Background
The frame for building and displaying needs to connect various sectional materials together, and the connecting piece is generally a connecting lock for locking the various sectional materials for connection, so that the frame is complex in manufacturing structure and high in cost, and meanwhile, the frame needs to be fixed by a tool, so that quick assembly and disassembly are affected. The company has disclosed a quick tool-less reed lock which can play a role in quickly connecting and locking profiles. However, the lockset is not fixed in place in use, and meanwhile, the lockset is not attractive enough and has the problem of complicated initial positioning.
Summary of the invention
The technical problem to be solved by the invention is to provide the tool-free connector with the bushing structure aiming at the defects of the prior art, so that the connector is more rapid and reliable in connection and can be directly connected with a section bar or an assembly part in a building structure in a locking way.
The technical scheme of the invention is as follows:
The utility model provides a no instrument connector, this connector includes bush and lock body two parts constitution, the embedding of lock body activity is in the bush, and the bush is cavity oblate cylinder structure, and there is the ear bush right-hand member, the lateral wall of bush be bilayer structure, there is left end closed pore in, the lateral wall on still have a slot hole, be located pore open-ended right side, the lateral wall of lock body has the round hole, the connecting rod passes the round hole activity pin joint of lock body and be in the slot hole in, with lock body and bush gomphosis.
Because the connecting piece and the round hole are in precise fit, the relative positions of the lock body and the connecting piece are fixed, and the lock body is pinned into the long hole on the bushing, so that the lock body can move left and right in a certain range along the long hole direction of the bushing.
The ears of the bushing are intended to be fixed from the right and the edges of the profile.
The lock body is also of a hollow flat cylinder structure, the right end of the lock body is provided with a cover plate, the left end of the lock body is provided with a locking claw, the middle section of the lock body is provided with a pull rod, the pull rod penetrates through the cover plate and is movably and eccentrically hinged with the locking handle, the locking claw is connected to the other end of the pull rod, and the locking handle can drive the pull rod through eccentric overturning, so that the locking claw can be in a closed or open state.
Further, the middle section of the pull rod is provided with a spring. Thus, when the pull rod is in a relaxed state, the pull rod is rebounded by the spring, and the pull rod can be easily retracted.
Further, a spring is arranged in the pore canal of the bushing. Therefore, when the lock body is released at the beginning of installation, the lock body is sprung out by the spring until the connecting rod abuts against the outer end of the long hole, and at the moment, the locking claw is retracted in the bushing, so that the two profile frames are not blocked from being closed. Before the locking is needed, the whole lock body can move inwards by only compressing the lock body leftwards, the connecting rod moves to the other end of the long hole, and the locking claw stretches out of the corresponding distance, and the locking claw can be clamped outside the two sections by the distance so as to be fixed in the next step.
Preferably, the connecting rod is a flat-end screw.
Further, the bushing ears also have screw holes. When the bushing is installed, the bushing is fixed on one side of the section bar, so that the bushing is firmer and convenient to position.
Preferably, screw fixing holes are formed in two sides of the cover plate, and the cover plate and the lock body are fixed through self-tapping screws. The cover plate is a reference for the overturning movement of the handle, and the cover plate is more attractive.
Furthermore, the left end part of the pull rod of the lock body is provided with two mutually-intersected locking hooks, the right side of the intersection point is provided with a baffle column which is pin-connected on the lock body, the left end part of the locking hooks is also provided with a reverse part, the reverse part is inserted into a closed cavity, and the opening of the cavity can accommodate the reverse part to enter and exit. Such a structure may enable; when the pull rod is retracted, the reverse folding part can clamp the inner wall of the main closed cavity and can not move randomly, and when the pull rod is released, the pull rod can freely enter and exit the inner wall, so that the pull rod can be overturned and locked.
Preferably, the locking claw is three movable reeds. The two sections can be opened and clamped, and the opened thickness exceeds the thickness of the two sections when being opened, and the sections can be firmly locked together when being clamped.
The invention has the beneficial effects that:
1. According to the technical scheme, the lock body is embedded in the bushing, so that when the lock is used, the bushing is fixed on one side of a section bar to be connected through the lug, at the moment, the lock body and the lock claw are elastically contracted in the bushing, the two section bars are not blocked in splicing, then the lock body is pressed, the lock body moves inwards the bushing, the lock claw stretches out a certain distance, the two section bars can be clamped in the lock claw, then the handle is turned over, and the handle pulls the pull rod to lock the opened part of the lock claw, so that the two section bars can be spliced.
2. The invention is simple and quick, and realizes the locking of the profile without tools. Compared with the original connector, the connector is more convenient to install.
