Technical Field

The utility model relates to a hasp, in particular to a pull rod hasp lock.

Background

The hasp is an accessory for splicing objects in an overlapping way, is overlapped on two objects for fastening the objects, and is used for covering the box body tightly by a box cover if being used on the box body, and can be locked by a padlock at the same time, so that the hasp is convenient to open. Such snap lock products with simple structure, such as application number 201420583928.2 disclosed in chinese patent document, publication date 2015.03.11, utility model name "snap lock". Among them, other hasp locks are equipped with the handle to be used for metal cabinet door, and handle and lock are generally set up separately among these hasp locks that use in industry, need unblock earlier before using, then draw out the server with the help of the handle, need push in earlier when closing, lock again, therefore need further improvement and perfect.

Disclosure of Invention

In order to overcome the defects, the utility model aims to provide a pull rod hasp lock with linkage and positioning of a pull rod and a lock tongue piece for the field, so that the technical problems of poor structural design and inconvenient operation of the existing like products are solved. The purpose is realized by the following technical scheme.

A pull rod hasp lock is characterized in that an upper cover and a lower cover of the hasp lock are connected through screws to form a lock shell, a handle rod, a lock tongue block and a spring are arranged in the lock shell, and one end of the lock tongue block extends out of a lock hole in one side of the lock shell through the spring in a propping mode; the key point of the structural design is that one end of the handle rod extends out of one side of the lock shell, the other end of the handle rod extends out of the other side of the lock shell, the lock hole is located in one side of the lock shell between two sides of the handle rod, one side of the handle rod is symmetrically provided with a raised swing head in the lock shell, the swing head of the handle rod keeps offsetting to drive the spring bolt block to move with the arc surface symmetrically arranged on two sides of the spring bolt block in the lock shell, and the swing head of the handle rod keeps spacing with the arc surface on two sides of the spring bolt block in the lock shell. Thereby the handle bar is spacing can't be extracted in the lock tongue piece of lock shell, and the lock tongue piece passes through the interact between the yaw of handle bar and the arcwall face of lock tongue piece and drives the lock tongue piece and remove, makes the lockhole that one end of lock tongue piece stretched out or retract the lock shell, realizes the locking and the operation of opening of this hasp lock.

The handle rod is L-shaped, and the L-shaped bent end of the handle rod extends out of the lock shell and is limited by the lock shell. The L-shaped handle rod is convenient for the rotation operation of the handle rod.

The rotation stroke of handle rod is 90 degrees angles. The stroke satisfies the telescopic stroke of the lock tongue block, the holding effect of the swing head on one side of the pull rod in the lock shell and the arc-shaped surface of the lock tongue block is guaranteed, the whole size is small, and the cost is low.

And a reset torsion spring is arranged on the outer diameter of the handle rod in the lock shell. Thereby being convenient for the handle rod to reset after rotating and waiting for the next opening operation.

The handle rod extends out of the other end of the lock shell, the other end of the handle rod is located in an extending hole of the lock shell, a protruding limiting head is arranged at the end of the handle rod in the lock shell, and the limiting head is attached to an orifice of the extending hole in the lock shell. Thereby preventing the interference of the handle bar, facilitating the installation of the hasp lock and further stabilizing the handle bar for use in the lock shell.

The handle rod extending holes on two sides of the lock shell are positioned at the joint of the upper cover and the lower cover, and the rod body in the lock shell of the handle rod and the L-shaped bent section of the outer diameter of the lock shell are integrally formed. The structure is convenient for the production and the processing of the handle rod in the hasp lock and the integral assembly of the hasp lock.

The handle rod is characterized in that the rod body in the lock shell and the L-shaped bent section of the outer diameter of the lock shell are separated into two parts and connected into a whole. Therefore, the structural design that the extending hole of the lock shell is positioned at the joint of the upper cover and the lower cover is not required to be considered.

The handle rod L-shaped bent end of the lock shell extends out of a side surface edge opening and is provided with an outer diameter ring rib, and the lock shell is cuboid. The structure is convenient for the whole hasp lock to be rapidly installed in the installation hole of the metal cabinet door.

The utility model has reasonable structural design, beautiful appearance, good prying-resistant, theft-proof and energy-saving effects and long service life; the anti-prying intelligent lock is suitable for being used as an anti-prying intelligent lock of locks such as an electronic cabinet door lock and the like, and the structure of the like is improved.

Figure number and name: 1. the handle comprises a handle rod 101, a swing head 102, a limiting head 2, a bolt block 201, an arc-shaped surface 3, a spring 4, an upper cover 5, a screw 6, a lower cover 601 and a lock hole.

Detailed Description

The structure and use of the present invention will now be further described with reference to the accompanying drawings. As shown in fig. 1-5, the upper cover 4 and the lower cover 6 of the hasp lock are connected by a screw 5 to form a lock case, a handle bar 1, a lock tongue piece 2 and a spring 3 are arranged in the lock case, and one end of the lock tongue piece is propped by the spring to extend out of a lock hole 601 at one side of the lock case. The concrete structure is as follows: the handle rod is L-shaped, the bent L-shaped end of the handle rod extends out of and is limited to one side of the lock shell, the other end of the handle rod extends out of the other symmetrical side of the lock shell, the tail end of the handle rod at the end is positioned in an extending hole of the lock shell, the end of the handle rod in the lock shell is provided with a raised limiting head 102, the limiting head is attached to an orifice of the extending hole in the lock shell, the lock hole is positioned in the lock shell at one side between two sides of the handle rod, raised swinging heads 101 are symmetrically arranged at one side in the lock shell at the other end of the handle rod, the swinging heads of the handle rod and arc surfaces 201 symmetrically arranged at two sides of the lock tongue block in the lock shell keep abutting to drive the lock tongue block to move, and the swinging heads of the handle rod and the arc surfaces at two sides of the lock.

The rotation stroke of above-mentioned hand lever is 90 degrees angles, and the handle lever of lock shell both sides stretches out the hole and is located upper cover and lower cover junction, and the body of rod is equipped with the opening with the L font bending section integrated into one piece of lock shell external diameter in the lock shell of handle lever, upper cover one side end angle of L font bending section one side, and the opening is located extension hole department, and the lock shell side bead of this side is equipped with outer diameter circle muscle, and the lock shell is the cuboid.
