Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
Example 1
As shown in fig. 1, a folder casting comprises a folder upper cover 1, a folder lower cover 2 and a hinge part 3, wherein one ends of the folder upper cover 1 and the folder lower cover 2 are hinged through the hinge part 3, the hinge part 3 consists of a hinge shaft and a hinge shaft sleeve, one ends of the folder upper cover 1 and the folder lower cover 2 are connected with the hinge shaft sleeve, and then the hinge shaft penetrates through the hinge shaft sleeve to form a hinge, which is the most common hinge mode in the field. The one end that the hinge 3 was kept away from to the folder upper cover 1 is equipped with first connecting portion, and first connecting portion includes first clamp splice 14 and second clamp splice 15, and two clamp splices form a finger, and spread groove 4 is located between first clamp splice 14 and the second clamp splice 15 and is an open structure, and the one end that hinge 3 was kept away from to the folder lower cover 2 is equipped with the second connecting portion. The second connecting portion includes a shaft section of thick bamboo portion 5, and a shaft section of thick bamboo portion 5 is equipped with two altogether, and the symmetry sets up on the tip of folder lower cover 2, leaves certain space between two shaft section of thick bamboo portions 5, and the rotation is equipped with pivot 6 in two shaft section of thick bamboo portions 5, and the intermediate part of pivot 6 is exposed outside two shaft section of thick bamboo portions 5, and the intermediate position of pivot 6 is equipped with connecting rod 7 perpendicularly, and connecting rod 7 can rotate along with pivot 6 rotation, and the cover is equipped with compact heap 8 on the connecting rod 7, and compact heap 8 becomes cylindric. The tip that pivot 6 one end was kept away from to connecting rod 7 articulates there is rotatory handle 9, specifically, is hollow structure in the middle of the head of rotatory handle 9, and the both sides of rotatory handle 9 head are equipped with the pinhole, and the tip of connecting rod 7 is arranged in the hollow structure of rotatory handle 9 head, and the tip of connecting rod 7 also corresponds and is equipped with the pinhole, passes the pinhole of rotatory handle 9 head and the pinhole of connecting rod 7 tip with the round pin axle, and rotatory handle 9 can rotate relative connecting rod 7.
With reference to fig. 1 and 2, the head of the rotary handle 9 is a disc-shaped cam structure, which is an element with a curved profile, the position of the pin on the rotary handle 9 is the center of the rotation of the rotary handle 9, and one end of the head of the rotary handle 9 is closer to the center of the circle, and the other end is farther from the center of the circle. The top of the pressing block 8 is provided with an arc-shaped groove 10 matched with the head of the rotary handle. As shown in fig. 2 and 4, when the rotary handle 9 rotates clockwise, the distance between the center point of the pressing block 8 and the center point of the rotation of the rotary handle 9 is further and further increased due to the shape of the cam disk of the head of the rotary handle 9, and during the rotation, the head of the rotary handle 9 continuously applies pressure to the pressing block 8, and a larger friction force is generated between the head of the rotary handle 9 and the pressing block 8 due to the pressure, so that the two are further and further fixed.
The principle of this embodiment is: first, as shown in fig. 1, the folder is in an opened state, when the folder needs to be closed, the upper folder cover 1 and the lower folder cover 2 are closed, and then the connecting rod 7 is rotated to be clamped into the connecting groove 4 of the upper folder cover 1, and in this state, as shown in fig. 2 and 3, the rotating handle 9 is perpendicular to the upper folder cover 1 and the lower folder cover 2. Then locking is carried out, the rotary handle 9 is rotated clockwise, so that the head of the rotary handle 9 continuously extrudes the compression block 8, the compression block 8 also extrudes the upper folder cover 1, the connecting rod 7 has an upward force under the action of the rotary handle 9, the connecting rod 7 drives the lower folder cover 2 to be pulled upwards through the rotating shaft 6 and the shaft barrel 5, the compression block 8 extrudes downwards again, and drives the upper folder cover 1 to be extruded downwards, so that the upper folder cover 1 and the lower folder cover 2 are tightly covered, as shown in fig. 4, the rotary handle 990 degrees is rotated, at the moment, a large pressure exists between the head of the rotary handle 9 and the compression block 8, so that the friction force between the rotary handle 9 and the compression block 8 is large, the friction force is relatively stable, the rotary handle 9 is not easy to rotate, slipping cannot occur, and the upper folder is not separated from the lower folder. The locking structure is rapid and convenient, has a good stabilizing effect, and the compression block 8 is not easy to fall off.
Example 2
This embodiment has the same parts as embodiment 1, except that: the connecting rod 7 is in threaded connection with the rotating shaft 6, and the connecting rod 7 penetrates through the rotating shaft 6 and is connected with a nut 11. The connecting rod 7 is in threaded connection with the rotating shaft 6, so that the distance between the center point of the connecting rod 7 and the center point of the rotating shaft 6 can be adjusted, and the pressing force of the pressing block 8 after pressing can be changed. When the distance between the center point of the connecting rod 7 and the center point of the rotating shaft 6 is longer, as shown in fig. 2, the distance between the pressing block 8 and the rotating handle 9 is increased, the force applied to the pressing block 8 after the rotating handle 9 rotates is decreased, and the pressing block 8 is loosened. Similarly, when the distance between the center point of the connecting rod 7 and the center point of the rotating shaft 6 is short, the distance between the compressing block 8 and the rotating handle 9 is reduced, the force applied to the compressing block 8 after the rotating handle 9 rotates is increased, the compressing block and the rotating handle are tightened, and the tightness can be adjusted through the nut 11 and the connecting rod 7.
Example 3
In this embodiment, based on a further improvement of embodiment 1 and embodiment 2, a top block 12 and a spring 13 are sleeved on the connecting rod 7, the top block 12 is located below the pressing block 8, the spring 13 is located below the top block 12, and the diameter of the top block 12 gradually increases from top to bottom. When the connecting rod 7 is clamped into the connecting groove 4, if no force exists between the connecting rod 7 and the connecting groove, for example, a human hand is temporarily separated from the rotating handle 9, the rotating handle 9 may rotate anticlockwise to drop as shown by an arrow in fig. 3, after the top block 12 and the spring 13 are arranged, as shown in fig. 3, the top block 12 applies a certain acting force to the first clamping block 14 and the second clamping block 15 under the action of the spring 13 after the connecting rod 7 is clamped into the connecting groove 4, so that friction force is generated between the top block 12 and the first clamping block 14 and the second clamping block 15, and the situation that the rotating handle 9 rotates anticlockwise to drop is avoided.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
