Description

Technical Field

[0001] The utility model relates to a folder and belongs to the technical field of machinery. Background Art

[0002] Application No. 201820855169.9 discloses a foot-operated folding scooter. The folding switch utilizes a lever principle. The folding switch tilts a movable shaft, causing it to disengage from a stop slot at one end of an arc-shaped slot. The folding body is then rotated, causing the stop slot at the other end of the arc-shaped slot to lie below the movable shaft. Releasing the folding switch allows the movable shaft to fall into the stop slot at the other end of the arc-shaped slot, achieving folding. The foot-operated folding switch is inconvenient to operate. Utility Model Content

[0003] The utility model solves the technical problems existing in the prior art, thereby providing a folder.

[0004] The existing technical problems are solved by the following technical solutions: a folder, a straight tube with a sliding groove, connecting plates on both sides at the lower part of the straight tube, the connecting plates with connecting holes, the sliding groove is located above the connecting plate, the sleeve has a transverse axis hole on the side and a connecting threaded hole on the front, the hook is connected to the connecting threaded hole by screws, and there are card slots distributed on the circular arc surface of the base, there are 2 card slots, and the circular arc rear part of the base has a limiting groove, the limiting groove is connected to the baffle, the limiting groove and the baffle are fixed by bolts, the base has a center hole, the spring is installed in the sleeve and above the connecting plate, the transverse axis is installed under the spring and connected to the transverse axis hole and the sliding groove, the connecting plates on both sides are inserted into the base, and the connecting hole and the center hole of the straight tube are connected by a pin shaft and a left washer. The other end of the pin shaft is connected to the right washer and fixed by a nut.

[0005] There are more than two slots. Pull up the hook to move the sleeve upward, the horizontal axis will be separated from the slot, and the straight tube will rotate with the center hole as the axis. When the straight tube rotates to the position of another slot, the spring releases the pressure to clamp the horizontal axis into the slot.

[0006] The advantages of the utility model are: compact folding structure, exquisite appearance, simpler folding operation and firmer structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. As shown in the figure:

[0008] Figure 1 This is a diagram showing the structure of the present invention.

[0009] Figure 2 This is the second diagram showing the structure of the present utility model. DETAILED DESCRIPTION

[0010] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0011] Example 1: Figure 1 、 Figure 2 As shown, a folder, a straight tube 1, a sleeve 2, a base 3, a hook 4, a spring 5, a baffle 6, a horizontal axis 7, a pin 8, a nut 9, a right washer 10, a left washer 11, a bolt 12, a screw 13, a connecting hole 14, a horizontal axis hole 15, a connecting threaded hole 16, a sliding groove 17, a connecting plate 18, a slot 19, and a center hole 20. The straight tube 1 has a sliding groove 17, and the lower part of the straight tube 1 has connecting plates 18 on both sides. The connecting plate 18 has a connecting hole 14, and the sliding groove 17 is located above the connecting plate 18. The sleeve 2 has a side transverse axis hole 15 and a front connecting threaded hole 16. The hook 4 is connected to the connecting threaded hole 16 by screws 13. Slots 19 are distributed on the arc surface of the base 3. There are 2 or more slots 19. The arc rear part of the base 3 has a limiting groove, the limiting groove is connected to the baffle 6, and the limiting groove and the baffle 6 are fixed by bolts 12. The base 3 has a center hole 20, the spring 5 is installed in the sleeve 2 and above the connecting plate 18, the transverse axis 7 is installed below the spring 5 and connected to the transverse axis hole 15 and the sliding groove 17, the connecting plates 18 on both sides are inserted into the base 3, and the connecting hole 14 and the center hole 20 of the straight tube 1 are connected by the pin 8 and the left washer 11. The other end of the pin 8 is connected to the right washer 10 and fixed by the nut 9.

[0012] Pulling up the hook 4 causes the sleeve 2 to move upward, the horizontal axis 7 to disengage from the slot 19, and the straight tube 1 rotates around the center hole 20 until it reaches the position of another slot 19. The spring releases pressure to engage the horizontal axis 7 in the slot 19, and the position between the straight tube 1 and the sleeve 2 changes.

[0013] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
