Description

Technical Field

[0001] The invention relates to a handle plane lock in the field of mobile communication equipment, in particular to a ball-pair push-type handle plane lock. Background Art

[0002] A handle-type flat lock is a type of door lock with a handle, typically found in electrical cabinets used for products like mobile communication devices. These cabinets are typically made of steel and designed to protect the components, requiring a lock to prevent them from being opened. Existing handle-type flat locks typically consist of a base, handle, shaft, and steel bolt assembly. The base houses a lock cylinder assembly and button assembly for locking the handle, or a mounting plate extending from a handle mounting hole to secure the handle within the base and prevent it from being opened. As disclosed in the Chinese patent literature, application number 202310437653.5, application publication date 2023.07.14, invention name "Hidden handle plane lock"; the above-mentioned handle plane lock adopts pressing at the snap assembly to realize the locking and opening action of the handle, and the lock core assembly at the snap assembly to realize the unlocking and closing of the handle, but the above-mentioned products and similar products, in addition to setting a lock core or snap structure at one end of the handle, rarely use a lock core assembly at the rotating shaft at the other end of the handle to realize the unlocking and closing of the handle. The snap assembly has poor stability, is prone to failure after repeated use, and reduces the service life. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the present invention aims to provide a ball-pair push-type handle flat lock in the art. This solves the technical problems that existing similar products, in addition to providing a lock core or buckle structure at one end of the handle, rarely use a lock core assembly at the rotating shaft at the other end of the handle to unlock and lock the handle. The buckle assembly has poor stability, is prone to failure after repeated use, and has a shortened service life. This objective is achieved through the following technical solution.

[0004] A ball-pair push-type handle plane lock, one end of the handle of the handle plane lock is fixed in the handle groove at the top of the base through a locking mechanism, or is directly retracted into the handle groove at the top of the base by rotation, and the other end of the handle is provided with a handle shaft, one end of the handle shaft extends out of the shaft hole at one end of the handle groove in the top of the base, and a shaft sealing ring is provided on the outer diameter of the handle shaft in the base at the extended part; the key point of its structural design is that one end of the handle shaft of the handle is hingedly fixed to the outer diameters of both sides of the handle shaft through buckles or pins on both sides. A first lock core assembly is provided in the lock core groove at the top of the other end of the handle shaft. A protruding pin at the bottom of the first lock core assembly in the handle shaft is inserted into a slot fixed to the shaft bolt. One end of the shaft bolt extends out of the handle shaft and is inserted into a lock hole on the raised skirt extending from the bottom of the handle, or into a lock hole on the shaft seat in the base. The shaft seat is provided in the handle groove on one side of the shaft hole in the base. A raised limiting edge is provided on the outer diameter of the handle shaft in the handle groove of the base. The handle shaft is fixed to the shaft hole in the base via the shaft seat at the limiting edge. Thus, after the handle is unlocked by the first lock core assembly at one end, the locking mechanism at the other end of the handle is pressed or opened simultaneously to remove the handle from the base. The handle shaft is then rotated, and the handle shaft extending out of the base drives the lock bolt and the actuator mechanism such as the connecting rod assembly at the gear to rotate, thereby achieving unlocking. Alternatively, the above structure omits the locking mechanism at one end of the handle, and the handle is directly opened and locked by the lock core assembly at the handle shaft at the other end of the handle.

[0005] The following is a specific structure of the handle shaft of the above-mentioned handle, wherein one end of the handle shaft is hingedly fixed to the outer diameters of both sides of the handle shaft by clips or pins on both sides, and the handle shaft is symmetrically provided with spherical edges on both sides of the outer diameter above the limiting edge of the handle shaft, and snap hooks are provided at both ends of the opening on one side of the handle shaft at the bottom of the skirt plate of the handle, and snap heads are symmetrically provided on both sides of the arc side of the handle above the snap hooks, and the grooves between the skirt plate of the handle and the spherical edges on both sides of the handle shaft are fitted to form a spherical outer diameter, and the grooves between the two ends of the opening of the skirt plate of the handle and the snap hooks and the spherical edges on both sides of the handle shaft are parallelly fitted, and the opening at the arc side of the handle and the snap heads at both ends are fitted with the second step groove and the outer diameter above the spherical edges on both sides of the handle shaft, and the handle shaft is fixed in the shaft hole of the base through the shaft seat on one side of the locking mechanism at the limiting edge. At the same time, the arc side of the inner diameter of the shaft seat fits the spherical outer diameter formed by the skirt plate of the handle and the spherical edge of the handle shaft; the shaft bolt is arranged at the through hole in the groove between the spherical edges on both sides of the handle shaft. Therefore, the handle and the handle shaft do not need to be connected by a pin. Instead, the handle can be easily removed from the base during use by snapping on both sides. The handle shaft will not fall off the handle, but when the handle is turned, the handle will drive the handle shaft to rotate together. The snap hook of the handle engages parallel to the curved surface or guide groove of the groove of the handle shaft. When the handle is opened, the limit block is located on both sides of the symmetrical raised area on the lower pad.

[0006] A steel ball is positioned on one side of the handle shaft above the shaft bolt, propelled by a steel ball spring within the handle shaft. The steel ball is pressed against a positioning slot in the handle by the steel ball spring. The positioning slot in the handle corresponding to the steel ball facilitates positioning the handle when placed within the base and also facilitates positioning when removed from the base. The positioning slot is not limited to a single location.

[0007] A pad is provided on one side of the handle shaft below the steel ball, which abuts against the inner side of the handle skirt. This pad enhances and improves the friction when removing the handle from the base, and in conjunction with the steel ball, further improves the stability of the handle when removing or inserting it into the base, and also provides a dust-proof effect.

[0008] The width of the handle's snap head on both sides is greater than the width of the handle's sides and the skirt below. The top corner of the second step groove at the handle's rotating shaft corresponding to the snap head is chamfered. A first step groove is provided at the handle groove in the base corresponding to the snap head. The diameter of the handle's rotating shaft in the base on one side of the first step groove is greater than the width of the handle groove in the base. This prevents the handle from rocking or loosening in the handle groove of the base, and provides better orientation and positioning when the handle is placed in the base.

[0009] A reinforcing rib is provided between the spherical edge and the limiting edge of the handle shaft on the other symmetrical side of the inner shaft seat of the base. The reinforcing rib is provided with the through hole for the movement of the shaft bolt and symmetrically arranged airtight grooves.

[0010] A raised anti-collision column is provided in the middle of the bottom of the handle, an anti-collision sleeve is provided in the handle groove on the top of the base corresponding to the anti-collision column, an anti-collision spring is provided at the bottom of the anti-collision sleeve, and the anti-collision sleeve and the anti-collision spring are fixed in the handle groove on the top of the base by anti-collision screws.

[0011] The handle slot at the top of the base is waist-shaped, and a waist-shaped sealing groove is provided on the outer side of the skirt of the base. Mounting ears are symmetrically arranged on both sides of the outer diameter of the skirt. This facilitates installation of the handle slot at the top of the base corresponding to the mounting hole of the cabinet door. A door panel sealing ring is installed in the waist-shaped sealing groove of the base.

[0012] The outer diameter of the end portion of the handle shaft extending out of the base is provided with a retaining spring, thereby facilitating the assembly of the structure as a whole and preventing the handle shaft from being easily pulled out.

[0013] The locking mechanism comprises a second lock core assembly, a snap assembly, or a push button assembly. When the first lock core assembly at the handle shaft on one end of the handle is unlocked, the other end of the handle is unlocked via the locking mechanism. The second lock core assembly can be an existing similar lock core product. The snap assembly can be an existing similar product that uses a base inside the base and a hook on the handle to release it by pressing it, and then re-engage it by pressing it. The push button assembly has the following specific structural design.

[0014] The push button assembly is fixed to the handle through a fixing seat, and the shaft sleeve is installed from the bottom opening of one end of the fixing seat, and the bottom of one end of the shaft sleeve extends out of the bottom opening of the fixing seat, and the side blocks symmetrically raised on both sides of the outer diameter of the top opening of the other end of the shaft sleeve are inserted into the guide groove corresponding to the inner diameter of the bottom opening of the fixing seat; a pressing shaft is provided in the top opening of the shaft sleeve, and a pressing spring is provided in the spring groove at the bottom of one end of the pressing shaft in the shaft sleeve, and the other end of the pressing shaft extends out of the top of the other end of the fixing seat and is fixed with a steel bolt by a pressing screw, and the steel bolt is pressed against The corresponding base is provided with steel bolt grooves symmetrically on one or both sides; the sleeve is fixed in the fixed seat by pins symmetrically driven into the side blocks on both sides. At the same time, the ends of the pins extending from the inner walls on both sides of the sleeve are inserted into the spiral grooves on the outer diameter of the pressing shaft; the steel bolt of the push button assembly is pressed by the sleeve extending from the bottom of the fixed seat, and the spiral grooves on both sides of the pressing shaft in the sleeve interact with the pins on both sides, driving the pressing shaft in the sleeve and the steel bolt fixed to the pressing shaft to rotate, and the steel bolt and the steel bolt groove in the base are detached or locked. The above structural design is similar to the use of existing snap-on assemblies. The handle is locked to the base or detached from the base by pressing. The steel bolt rotates or resets during the pressing process.

[0015] The push button assembly's steel bolt has an open slot at the bottom of the handle. The outer ends of the top of the push button assembly's mounting base are fixed to the ends of the handle's open slot via screws. The push button assembly's steel bolt rotates within the handle's open slot. The above is a specific design for the steel bolt's rotating slot. Alternatively, a snap-fit ​​fixation method can be used, with space reserved for the steel bolt's rotation.

[0016] The present invention has a reasonable structural design, unique operation and great value for promotion and application. The lock core component for locking the handle is arranged at one end of the handle shaft; in particular, the push button component has a wide range of applications and can be applied to similar handle plane locks; it is suitable for use as a ball-pair push-type handle plane lock, as well as a structural improvement of similar products.
