Description

Clamp

Technical Field

The invention relates to the technical field of clamps, in particular to a clamp which is particularly suitable for file pieces.

Background

The file piece belongs to the stationery that relatively is used in daily work, life, has advantages such as easy operation, practicality and convenient, and it accomplishes file centre gripping through cassette, clamping lid and press from both sides the button cooperation, and the afterbody of pressing from both sides the button is connected with the base through the pivot, and the ubiquitous defect of anchor clamps at present is as follows: when the clamped folder is unlocked, the clamping button is required to deflect to the right side to unlock the folder and the base, the operation is troublesome, and the clamping button is required to deflect, so that the folder is usually required to be supported by the other hand to keep the folder stable during unlocking, the folder cannot be disturbed and shaken, more importantly, the deflection of the clamping button is substantially the distortion of the clamping button, and the connection position of the tail part of the clamping button and the base can cause damage to the clamping button in the repeated deflection process.

Disclosure of Invention

The technical problem to be solved by the invention is to provide the clamp which is simpler and more convenient to operate and can effectively avoid the damage of the clamp button.

In order to solve the technical problems, the clamp provided by the invention comprises a base, a clamping button, a clamping cover and a torsion spring; the clamp cover is arranged on the base through the auxiliary shaft, the tail part of the clamp button is arranged on the base through the main shaft, the torsion spring is positioned between the clamp cover and the clamp button, the torsion spring is sleeved on the main shaft, the base is provided with a lock hook,

The device also comprises a poking piece which is rotatably arranged on the base, wherein the poking piece is downwards inclined from the installation position and is positioned at the inner side of the base, and the poking piece is positioned below the lock hook;

the clamping button is provided with a movable clasp matched with the lock hook;

The movable clasp is characterized in that the locking hooks on the base are matched to complete locking, and the movable clasp rotates or deflects under the guidance of the poking piece. Through setting up plectrum and movable clasp, the clasp realizes anchor clamps locking, does not need the press from both sides the button swing during the unblock, but plectrum guide movable clasp swing, realizes that movable clasp breaks away from with the latch hook, and the plectrum guarantees that the hasp can not lock with the latch hook once more at the lift-back in-process, and the press from both sides the button and need not swing, only need perpendicularly downwards press or lift-back can.

The base on be equipped with the fore shaft, the plectrum install in the fore shaft through the pivot. Introduces the mounting position and the mounting mode of the poking plate, and fully utilizes the base structure.

The two torsion spring arms of the torsion spring are respectively connected with the clamp cover and the clamp button, the torsion spring arms connected with the clamp button are provided with bending parts serving as movable clasps, and the positions of the clamp button corresponding to the bending parts are provided with notches. The torsion spring arm plays a role of a movable clasp, and has excellent deformability due to the material, so the damage is avoided.

The clamping button is provided with a pressing hook, and the torsion spring arm is connected with the clamping button through the limiting of the pressing hook. The structure mainly aims at stabilizing the torsion spring arm, and the movable clasp can be ensured to be stable in the use process and can be accurately connected with the latch hook.

After adopting above structure, the clamp of the invention has the following advantages compared with the prior art:

The pulling piece and the movable clasp are matched for use, and the clamping button does not need to deviate when unlocking and only needs to vertically move up and down.

Drawings

FIG. 1 is a schematic diagram of a clamp according to the present invention;

FIG. 2 is a schematic view of another angle structure of the clamp of the present invention.

Detailed Description

The invention will be described in further detail with reference to the drawings and the detailed description.

Referring to fig. 1 and 2, the basic structure of the clamp of the invention is similar to that of a conventional clamp, and the clamp comprises a base 1, a clamp button 2, a clamp cover 3 and a torsion spring 4; the clamp cover 3 is arranged on the base 1 through the auxiliary shafts 5, two auxiliary shafts are arranged, the clamp cover can be kept stable during operation, the tail part of the clamp button 2 is arranged on the base 1 through the main shaft 6, the structure of the clamp button can be various, for example, the clamp button in a common file can be used, in the example, the clamp button in the common file is taken as an example, the torsion spring 4 is arranged between the clamp cover 3 and the clamp button 2, the torsion spring 4 is sleeved on the main shaft 6, and the base 1 is provided with the lock hook 7.

The invention differs from the prior art in that: the novel lock hook comprises a base 1, and is characterized by further comprising a poking piece 9, wherein the poking piece 9 is rotatably arranged on the base 1, the poking piece 9 is inclined downwards from an installation position and is positioned at the inner side of the base 1, and the poking piece 9 is positioned below the lock hook 7;

The clamping button 2 is provided with a movable clasp 8 which is matched with the lock hook 7;

the movable clasp 8 is characterized in that the locking hook 7 on the base 1 is matched to complete locking, and the movable clasp 8 rotates or deflects under the guidance of the poking piece 9.

The working principle is as follows: the locking of press from both sides the button in conventional mode the same, press the button of clamp just can realize latch hook and lock, but when the unblock, the vertical press button of clamp will slide along the inclined plane of plectrum after the contact of latch hook downshifting in-process with the plectrum, because the latch hook is the movable structure, consequently, can remove on the inclined plane of plectrum, after breaking away from with the plectrum, press from the end, the latch hook also can reset from the swing direction, the latch hook is in the below (the back) of plectrum, loosen the press hand, the clamp is risen, the latch hook contacts with the plectrum again, drive the plectrum and rotate, the latch hook moves along the back of plectrum again, the position that the latch hook breaks away from with the plectrum is higher than the position of latch hook, just so can avoid buckle and latch hook locking once again when unblock, up to this, whole unblock process ends, the anchor clamps locking or unblock process is complete.

As an improvement, the base 1 is provided with a locking notch 13, and the pulling piece 9 is arranged in the locking notch 13 through a rotating shaft 14. The structure is simple and practical, and is not described in excessive detail.

Specifically, two torsion spring arms 10 of the torsion spring 4 are respectively connected with the clamp cover 3 and the clamp button 2, the torsion spring arms 10 connected with the clamp button 2 are provided with bending parts serving as movable hooks 8, and the positions of the clamp button 2 corresponding to the bending parts are provided with notches 11. The notch is arranged to ensure that the clasp can be hooked with the lock catch smoothly, so that the clamp can work normally.

The movable clasp described in the above embodiment has an elastic reset structure or performance, and can reset through the structure, and also can reset by depending on the material itself. In the example, the elastic reset function of the clasp is realized by the elasticity of the material of the torsion spring.

The clamp button 2 is provided with a press hook 12, and the torsion spring arm 10 is limited by the press hook 12 and is connected with the clamp button 2. The structure can realize that the torsion spring arm can swing, does not influence the smooth swing of the bending part, and can ensure that the torsion spring arm can keep stable.

The clamp is particularly suitable for being used in folders.
