Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of lock accessories, in particular to a lock knob. BACKGROUND

[0002] The lock knob is a component installed on a lock and operated by rotation to open and lock. It usually works with components such as a lock tongue and a lock core to achieve the locking and unlocking functions of a door. The connection between the knob and the lock rod is mainly fixed or detachable. The detachable knob can be separated from the lock rod to avoid unrelated personnel operating the lock and prevent misoperation, thus providing higher security.

[0003] Different fields and enterprises will redesign the linkage assembly structure between the knob and the lock rod to make their products more secure. The most common linkage assembly structures on the market include triangles, quadrilaterals, hexagons, and other irregular shapes. The existing knobs can only achieve single linkage adaptation, which requires carrying multiple knobs when facing different shapes of linkage assembly structures. This affects the portability of the staff and greatly increases the production cost of the knob. The improvement is born to solve the above problems. SUMMARY

[0004] The utility model aims to provide a lock knob with better portability and lower production cost.

[0005] The above technical purpose of the utility model is achieved by the following technical scheme: a lock knob includes a knob body with a linkage docking hole. The knob body includes a gripping section for the hand to grip and a docking section for docking with the lock rod. The linkage docking hole is formed in the docking section. A detachable docking linkage structure is provided between the gripping section and the docking section. The docking linkage structure constitutes a steering linkage between the gripping section and the docking section along the circumference of the linkage docking hole.

[0006] By adopting the above technical scheme, the docking linkage structure is provided to constitute a steering linkage between the gripping section and the docking section, so that the staff can operate the linkage docking hole on the docking section to control the lock to lock when gripping the gripping section. When facing different shapes of lock rods, the docking linkage structure can be split to replace the docking section separately. By this structure, the staff only needs to carry one gripping section and multiple docking sections during operation, reducing the volume and weight of carrying, making the lock knob more portable. This structure also reduces the cost of processing the gripping section, making the production cost lower.

[0007] Further arrangement is that the docking linkage structure comprises a docking slot arranged on the holding section and a docking plug fixedly arranged on the docking section and used for being inserted into the docking slot, and when the docking plug is inserted into the docking slot, the turning linkage of the holding section and the docking section is formed.

[0008] By adopting the above technical scheme, the docking plug is inserted into the docking slot to form the turning linkage of the holding section and the docking section, and when the docking plug is pulled out of the docking slot, the holding section and the docking section can be separated to achieve the detachable linkage purpose.

[0009] Further arrangement is that a detachable limiting structure is arranged between the docking slot and the docking plug, and when the docking plug is inserted into the docking slot, the limiting structure limits the docking plug from being separated from the docking slot.

[0010] By adopting the above technical scheme, the limiting structure is arranged to avoid the accidental separation of the docking plug and the docking slot, so that the operation process is more convenient, and when the separation of the two is needed, the limiting of the limiting structure is released.

[0011] Further arrangement is that the limiting structure is a limiting magnetic block fixedly arranged at the bottom of the docking slot and used for adsorbing and fixing the docking plug.

[0012] By adopting the above technical scheme, the limiting magnetic block adsorbs the docking plug to form the limiting between the holding section and the docking section, so as to avoid the accidental separation of the two; and when the separation of the two is needed, the convenient separation of the two can be realized by applying a force greater than the magnetic force.

[0013] Further arrangement is that an ejection structure is arranged in the holding section, and the ejection structure is used for driving the limiting structure to switch from the limiting state to the non-limiting state.

[0014] By adopting the above technical scheme, the arrangement of the ejection structure can better control the switching of the limiting structure, so that the operation is more convenient.

[0015] Further arrangement is that the ejection structure comprises a mounting hole arranged on the holding section and communicating with the outside and the bottom of the docking slot, a connecting hole arranged on the limiting magnetic block and coaxial with the mounting hole, and an ejector rod slidingly arranged in the mounting hole, and the connecting hole communicates with the mounting hole, and the axis of the mounting hole is parallel to the opening direction of the docking slot.

[0016] By adopting the above technical scheme, when the docking plug is inserted into the docking slot and is adsorbed and fixed by the limiting magnetic block, the docking plug is driven to move away from the docking slot by pressing the ejector rod, so as to realize the convenient replacement of the docking section.

[0017] Further arrangement is that a limiting block is arranged on the ejector rod and used for limiting the ejector rod from separating from the mounting hole.

[0018] By adopting the technical scheme, the falling of the ejector rod is avoided by arranging the limiting block.

[0019] Further, the cross section of the docking slot is polygonal, and the shape of the docking plug is matched with the shape of the docking slot.

[0020] By adopting the technical scheme, the linkage plug-in is formed.

[0021] In summary, the utility model has the following beneficial effects: the utility model has better portability and lower production cost. BRIEF DESCRIPTION OF DRAWINGS
