Abstract

The utility model discloses a pinchcock for a folder, comprising a lateral plate, a motherboard, a plurality of fixing lugs arranged above the motherboard, a torsion spring, a handle, a treadle bar, two Z type swiveling jibs, and the rivet which supports the torsion spring is an U-shaped rivet. One end of the U-shaped rivet is threaded through the lateral plate and torsion spring, and then is arranged above one fixing lug; the other end is threaded through the lateral plate and is connected with another fixing lug. The spring folder of the utility model solves the motherboard warp problem, under the same chucking powers; the motherboard does not warp, but saves the motherboard material by more than 20 percent.

Description

Elastic binder

(1) technical field:

The utility model relates to a kind of spring clip that is used on the file.

(2) background technology:

Spring clip on the existing file folder comprises base plate, and base plate is provided with a plurality of fixedly ears, and torque spring is installed in fixedly on the ear by I snap riveting nail, and an end of torque spring is stuck in the handle bottom, and other end bending also flexibly connects with press strip; The torque spring both sides are respectively equipped with a Z type pivoted arm, an end of two Z type pivoted arms and fixedly ear flexible connection, and the other end and press strip flexibly connect; The handle sidepiece is provided with the bayonet lock of a projection, and the spring clip side plate is provided with and the corresponding hole of this bayonet lock.This spring clip has been continued to use for many years, but there is a problem in it, and promptly clip moves downward because handle drives torque spring when clamp position, and the pressure of generation makes and base plate two ends diagonal discontinuity causes base plate that warping phenomenon is arranged.At present, two kinds of methods that reduce the base plate warpage are arranged: 1, increase base plate thickness, with increase base plate rigidity, thereby reduce warpage, but this method can increase the baseboard material cost; 2, reduce spring force, but this method can make the file of clamping come off out easily from clip.

(3) summary of the invention:

Technical problem to be solved in the utility model just provides a kind of elastic binder, and it can solve the base plate warpage issues, and has saved cost.

In order to solve the problems of the technologies described above, the technical solution that elastic binder of the present utility model adopted is such, it comprises side plate, base plate, is located at a plurality of fixedly ears, torque spring, handle, press strip, two Z type pivoted arms on the base plate, the rivet of supporting torque spring is a U snap riveting nail, one end of this U snap riveting nail passes and is installed in one behind side plate and the torque spring fixedly on the ear, the other end also pass side plate with another fixedly ear be connected.

Adopt after the technique scheme, because elastic binder of the present utility model will support the I snap riveting nail of torque spring and change U snap riveting nail into, torque spring is enclosed within on a section of U snap riveting nail, therefore when clamping, another section of U snap riveting nail decomposes clamping force on the whole base plate, whole bottom slab stress is evenly distributed, thereby has solved the base plate warpage issues.This elastic binder is under identical chucking power situation, and not only base plate can warpage, also can save the base plate materials more than 20%.

(4) description of drawings:

Fig. 1 is the structural representation of the utility model elastic binder under clamped condition;

Fig. 2 is the structural representation of the utility model elastic binder under releasing orientation.

(5) specific embodiment:

Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.

In conjunction with Fig. 1, Fig. 2 as seen, the utility model elastic binder comprises base plate 1 and side plate 2, base plate 1 is provided with a plurality of fixedly ears 3, the rivet of supporting torque spring 4 is a U snap riveting nail 5, one end of this U snap riveting nail 5 passes and is installed in one behind side plate 2 and the torque spring 4 fixedly on the ear 3, the other end also pass side plate 2 with another fixedly ear 3 be connected.One end of torque spring 4 is stuck in handle 6 bottoms, and the other end is crooked and flexibly connect with press strip 7.Torque spring 4 both sides are respectively equipped with an end of 8, two Z types of Z type pivoted arm pivoted arm 8 and fixedly ear 3 flexible connections, and the other end and press strip 7 flexibly connect.Handle 6 sidepieces are provided with the bayonet lock 9 of a projection, and side plate 2 is provided with and this bayonet lock 9 corresponding holes 10.

On described U snap riveting nail two ends and the base plate fixedly the tie point position of ear be not limited to shown in Fig. 1 and Fig. 2, with realization the purpose of this utility model degree of being.

Claims

1, a kind of elastic binder, comprise side plate, base plate, be located at a plurality of fixedly ears, torque spring, handle, press strip, two Z type pivoted arms on the base plate, it is characterized in that: the rivet of supporting torque spring (4) is a U snap riveting nail (5), one end of this U snap riveting nail (5) passes and is installed in one behind side plate (2) and the torque spring (4) fixedly on the ear (3), the other end also pass side plate (2) with another fixedly ear (3) be connected.
