In the structure, one end of the sliding block head of the sliding block is higher, so that the thickness of a product is higher; the slider and the handle are fixed on the shell through the knurled cylindrical pin and the split pin shaft, and the spring piece is fixed on the handle through riveting, so that assembly and production are inconvenient.
Disclosure of Invention
In order to overcome the defects, the invention aims to provide an improved double-locking lock catch for the field, so that the technical problems of inconvenient assembly and production and high production cost of the existing similar products are solved. The purpose is realized by the following technical scheme.
An improved double-locking lock catch is characterized in that a knob is arranged in the middle of the top of a handle of the lock catch, a spring bolt at the bottom of the handle is riveted with the knob, a sealing ring is arranged at the joint of the spring bolt and the knob, a spring bolt hole is formed in the middle of a sliding block corresponding to the spring bolt, one end of the handle is hinged and fixed to one end in a lock shell through a pin, an arc-shaped opening is formed in the other end of the handle, the sliding block is arranged in the lock shell between the handle and the lock shell, the sliding block and the handle are arranged in a shell opening of the lock shell, an installation hole is formed; the key points of the structural design are that a hook hole is formed in one end of a pin of the sliding block, a raised barb head is arranged at the bottom of the pin of the handle, a barb groove is formed between the barb head of the handle and one side edge of the pin of the handle, the handle is hinged and fixed on the lock shell through the pin, and the barb head of the handle is positioned in the lock hole of the sliding block; when the handle is opened, the barb head of the handle pushes the sliding block to move through the locking head hole of the sliding block, and then the barb groove of the handle pushes the inner diameter edge of one side of the pin of the barb head hole in the sliding block to move continuously. Therefore, when the sliding block is fixed through the pin between the handle and the lock shell, the sliding block is clamped between the handle and the lock shell, and the hook head hole of the sliding block and the hook groove of the handle interact with each other through rotation of the handle, so that the sliding block is driven to move in the lock shell.
The barb head of handle and the gib head hole interference lock of slider, barb head one side and the gib head hole drill way parallel and level of slider in the barb inslot of handle, another side direction notch perk of the barb inslot of handle is the inclined plane of taper, and the inclined plane one side in barb groove is higher than barb head one side. The mutual interaction and mutual linkage effect between the barb head of the handle and the barb head hole of the sliding block and between the barb groove of the handle and the barb head hole of the sliding block are further ensured.
The utility model discloses a handle, including the slider, the handle is equipped with the lock tongue hole of slider, the lock tongue hole bottom drill way of slider is equipped with the jump ring of U font, and the both sides of jump ring are "nearly" font arch respectively to protruding end stretches out the lock tongue hole internal diameter both sides that are located the slider, and the handle bottom knob post bilateral symmetry that lock tongue hole both sides jump ring corresponds is equipped with the constant head tank, and the constant head tank is located the top of spring bolt, the constant head tank and the jump ring interference lock of handle, and the spring bolt one end. When the lock catch is in a closed state, the handle is buckled and fixed in the lock catch through the clamp spring, namely the handle is fixed on the clamp spring of the sliding block; and when the spring bolt is in the locking state, the clamp spring plays the role of a second lock hole above the spring bolt hole on the sliding block.
The other end of the sliding block is provided with a bolt end which extends outwards and extends out of the lock shell, the sliding block is provided with a kidney-shaped hole, the kidney-shaped hole is provided with a lock shell hole corresponding to the bottom of the sliding block and the lock shell of the bolt end, and the external connecting rod is connected with the kidney-shaped hole of the sliding block through the lock shell hole of the lock shell. The above-mentioned handle drives the slider and removes, makes the bolt end of slider drive the linkage of external connecting rod and realizes the embodiment that this hasp was opened, and it also can adopt the slider one side to stretch out the bolt of lock shell hole and slide the structural design who realizes opening and closing from top to bottom.
The lock shell below the pin of the handle is a closed plane. Compared with the existing design that the opening of the lock shell is broken, the lock shell does not need to borrow 3-4mm of space towards the inner side of the cabinet body in the movement process of the handle and the sliding block.
The knob is replaced by a lock core assembly, the lock core assembly comprises a rotating shaft and a lock core, and the rotating shaft of the lock core assembly is connected with the lock tongue. The above is an embodiment in which the lock bolt is driven by the cylinder assembly to rotate to open the lock catch.
The bilateral symmetry of slider is equipped with the spacing groove that the equidistance distributes, the lock shell inner wall of slider top be equipped with the bellied limit post of spacing groove correspondence, the limit groove of slider and the limit post of lock shell pack into the lock shell to make the slider slide in the lock shell through the dislocation. The structure further enables the sliding block to be limited in the lock shell to move.
The lock shell is characterized in that pin limiting columns are symmetrically arranged on two sides of the lock shell at the hinged and fixed position of the handle above the sliding block, the outer edges of two sides of a hook hole of the sliding block are smaller than the edge of a limiting groove of the sliding block, limiting edges are arranged between the handle and the barb head at two sides of the pin limiting columns, and the rotating angle of the handle ranges from 0 degree to 120 degrees. Therefore, the rotation angle of the handle is limited at the maximum rotation angle through the pin limiting column of the lock shell at the pin, the sliding block can be installed in the lock shell and can be limited in the lock shell through the side limiting column of the lock shell, and the rotation angle range of the handle meets the linkage between the handle and the sliding block.
The invention has reasonable structural design, simple use, convenient production and assembly, low production cost and good stability and safety; the lock catch is suitable for being used as a lock catch of cabinets in the industries of telecommunication, electric power, automatic control and the like, and the structure of similar products is improved.
