Description

Technical Field

[0001] The utility model relates to the technical field of paper clamping devices, in particular to a suspension clamp and a plate clamp. Background Art

[0002] The existing paper clip generally includes a board body and a clamp arranged on the board body. The clamp of the traditional paper clip generally adopts a spring clamp. When using it, one hand needs to press the spring clamp and the other hand needs to load the paper, which is very inconvenient to use.

[0003] In order to solve the above technical problems, a plate clamp has been developed, the structure of which is as follows: Figure 1 As shown, it includes a plate body 1a and a suspension clamp, the suspension clamp includes a clamping plate 2a, a torsion spring 3a, a spring piece 4a and a pressing piece 5a, the clamping plate 2a is mounted on the plate body 1a through a rotating shaft and can be turned upside down, one side of the clamping plate 2a is a paper pressing side, the torsion spring 3a is mounted on the rotating shaft and abuts against the clamping plate 2a, and is used to provide a clamping force pressing the paper pressing side to the clamping plate 2a, the pressing piece 5a can be turned upside down and arranged in a pressing piece opening 6a of the clamping plate 2a, and a locking step 7a is also provided in the pressing piece opening 6a, the spring piece 4a is installed between the plate body 1a and the clamping plate 2a, one end of the spring piece 4a is fixed to the plate body 1a, and the other end is a free end 9a. When in use, the clamping plate 2a is pressed downward to flip it counterclockwise and open. At the same time, the free end 9a of the spring 4a can slide along the clamping plate 2a and be stuck in the clamping angle formed by the top pressing end 8a of the pressing plate 5a and the locking step 7a, so as to support the clamping plate 2a to remain in an open state, and paper can be put in at this time; after the paper is loaded, the pressing plate 5a is pressed, and the free end 9a of the spring 4a is disengaged from the clamping angle to unlock the clamping plate 2a. The clamping plate 2a flips clockwise under the action of the torsion spring 3a until the paper is clamped. The hovering clamp of the board clamp can open the clamping plate 2a and keep it in a hovering state when in use, so there is no need to keep pressing it with your hand. After the paper is loaded, the pressing plate 5a is pressed again to unlock the clamping plate 2a and clamp the paper, which is very convenient to use.

[0004] However, the existing plate clamp suspension clamp still has the following technical problems: the free end 9a of the spring piece 4a is used to slide and position it to the clamping angle formed by the top pressing end 8a of the pressing piece 5a and the locking step 7a. Since the sliding of the free end 9a of the spring piece 4a and the formation of the clamping angle are dynamic and affected by the manual pressing operation and the deformation of the spring piece itself, and the strength and depth of the manual pressing operation, as well as the deformation of the free end 9a of the spring piece 4a are uncontrollable and uncertain, it is difficult to ensure the stability of the two dynamic structures during the cooperation process. For example, when the manual pressing force is large and deep, the elastic force released by the free end 9a of the spring piece 4a is also large, and it is very likely to rush out of the clamping angle and cause the free end 9a of the spring piece 4a to fall off, thereby failing to ensure that the free end 9a of the spring piece 4a can be reliably inserted into the clamping angle every time. Utility Model Content

A guide surface 11 is also provided on the front side of the first protrusion 8 and above the slot 10, which is used to make the guide surface 11 abut against the barb 9 and guide the barb 9 to rotate and lock into the slot 10 when the clutch side 7 of the clamping plate 1 is pressed. The slot 10 extends horizontally inward from the front side of the bottom of the first protrusion 8 for a period of time and then extends vertically upward for a period of time.

In this embodiment, the snap structure 12 includes two limiting grooves 19 arranged on the left and right sides of the pressing plate 3, and a limiting protrusion 18 arranged in the pressing plate 5 and matching with the two limiting grooves 19. Of course, the number of limiting protrusions 18 and limiting grooves 19 can also be one, and the positions of the limiting protrusions 18 and the limiting grooves 19 can also be interchanged, that is, the limiting protrusions 18 are set on the pressing plate 3, and the limiting grooves 19 are set in the pressing plate 5.

[0034] The left and right sides of the clamping plate 1 are directly or indirectly mounted on the plate body 4 through two first rotating shafts 13 , two torsion springs 2 are provided and respectively mounted on the two first rotating shafts 13 ; the first protrusion 8 is provided below the clamping plate 1 and between the two first rotating shafts 13 .

[0035] The pressing sheet 3 can be installed in the pressing sheet port 5 of the clamping plate 1 in an upside-down manner through the second rotating shaft 14. The second rotating shaft 14 is parallel to the first rotating shaft 13 and is located in front of the first rotating shaft 13; the second rotating shaft 14 can be one and pass through the entire pressing sheet 3 from left to right, or the second rotating shaft 14 can be two, which are respectively arranged on the left and right sides of the pressing sheet 3. In this embodiment, a structure of two second rotating shafts 14 is adopted; the barb 9 is arranged on the front side of the second rotating shaft 14, and the snap structure 12 is arranged on the rear side of the second rotating shaft 14.

[0036] The paper pressing side 6 of the clamping plate 1 is further provided with a second protrusion 15 for abutting against the head of the paper, and the second protrusion 15 is directly or indirectly fixed to the plate body 4 .

[0037] It also includes a base plate 16, on which the clamping plate 1, the first protrusion 8 and the second protrusion 15 are all arranged. In this embodiment, the first protrusion 8 and the second protrusion 15 are both integrally formed with the base plate 16, and a bearing seat 20 for supporting the first rotating shaft 13 is integrally formed on the base plate 16. The first rotating shaft 13 is mounted on the bearing seat 20, and the clamping plate 1 is mounted on the first rotating shaft 13. The base plate 16 is used to be installed on the plate body 4, so that the clamping plate 1, the first protrusion 8 and the second protrusion 15 are indirectly fixed to the plate body 4 by using the base plate 16; the base plate 16 is provided with a countersunk hole 17 for connecting with the plate body 4.

[0038] The working principle of the hovering fixture in this embodiment is as follows:

[0039] In the initial state, the barb 9 of the pressing sheet 3 is separated from the slot 10 of the first protrusion 8, and the limiting groove 19 of the pressing sheet 3 is snap-connected with the limiting protrusion 18 of the pressing opening 5. At this time, the pressing sheet 3 and the clamping plate 1 are limited together, and the clamping plate 1 is pressed toward the paper pressing side 6 under the action of the torsion spring 2;

[0040] When the clamp needs to be opened, the clutch side 7 of the clamping plate 1 is pressed. Since the pressing piece 3 and the clamping plate 1 are limited together, the pressing piece 3 will rotate downward with the clamping plate 1. When the barb 9 of the pressing piece 3 rotates to abut against the first protrusion 8, the barb 9 is clamped between the pressing piece opening 5 and the guide surface 11 of the first protrusion 8, so that the barb 9 can be rotated and inserted into the card slot 10 under the guidance of the guide surface 11, so as to realize the connection between the pressing piece 3 and the first protrusion 8. At the same time, the rear side of the pressing piece 3 is pushed out of the pressing piece opening 5 to separate the buckle structure 12.

[0041] When the clutch side 7 of the clamping plate 1 is released, the clamping plate 1 is subjected to the force of the torsion spring 2, and the force is transmitted to the pressing plate 3, so that the barb 9 of the pressing plate 3 tightly presses upward against the top of the card slot 10, and the barb 9 is firmly combined with the card slot 10. At this time, the turning axis of the pressing plate 3 and the turning axis of the clamping plate 1 are both restricted, that is, the positions of the first rotating shaft 13 and the second rotating shaft 14 are both restricted, so that the clamping plate 1 cannot rotate either, and then stays in the open position to achieve hovering. At this time, paper can be loaded, and the loaded paper can be aligned by the second protrusion 15;

[0042] When it is necessary to clamp the paper, just press the back side of the pressing piece 3, that is, push the pressing piece 3 out to the side outside the pressing opening 5. At this time, the hook 9 on the front side of the pressing piece 3 will disengage from the slot 10 of the first protrusion 8, and the pressing piece 3 will be separated from the first protrusion 8, thereby unlocking the clamping plate 1, and the pressing piece 3 pressed into the pressing opening 5 will be re-connected with the pressing opening 5 by snapping. After releasing the pressing piece 3, the clamping plate 1 drives the pressing piece 3 limited therewith to flip to the paper pressing side 6 under the action of the torsion spring 2, and the paper is clamped.

[0043] Embodiment 2:

[0044] like Figure 8 As shown, combined with Figure 2-7 This embodiment provides a plate clamp, including a plate body 4, and also includes the suspension clamp 21 in the first embodiment, and the suspension clamp 21 is installed on the plate body 4.
