Hereinafter, a cover opening and closing device according to the present invention will be described in detail as a preferred embodiment. It is pointed out that the accompanying drawings are only one embodiment in which the technical spirit of the present invention is embodied, and embodiments that include changes of a degree apparent to those skilled in the art are included in the scope of the present invention.

Figure 3 corresponds to a schematic cross-sectional view of the cover opening and closing device is configured as a preferred embodiment, Figure 4 is a perspective view of the fixture and Figure 5 shows a state in which the gear is coupled to the fixture.

As shown, the cover opening and closing device according to the present invention includes the fastener 100, the gear 200, and the handle 300 as main components. The cover opening and closing device is a device for operating so as to open and close the cover provided in the container body, the cover is usually coupled to the upper side of the container body.

The fixture 100 is installed near any one side of the container body or two or more upper sides of the container body to be integrated with the container body. The fixture 100 is formed with two support blocks 110 protruding at a spaced distance on the front surface as shown in Figure 4, the locking groove 120 is concavely opened on the upper surface of the support block 110. ) Is provided. And the elastic piece 130 having elasticity is formed between the support block 110, the elastic piece 130 is preferably to be produced integrally when forming the fixture 100. In this example, the fastener 100 is suitable for molding by plastic injection molding or the like, and since only one end of the elastic piece 130 is constrained with the fastener 100, the other end forms a free end. Therefore, the elastic piece 130 has its own elasticity, and preferably determine the shape of the distal end portion of the elastic piece 130 according to the outer surface shape of the gear 200 to be described later.

Gear 200 is installed between the two support blocks 110 constituting the fixture 100, the gear 200 is disposed so as not to interfere with the locking groove (120). Since the gear 200 located between the support blocks 110 should be installed to be rotated, the two support blocks 110 are preferably provided with mounting holes 115 for shaft installation in the two support blocks 110. Do. And the gear 200 is installed between the support block 110 should be installed in the form that the outer surface is engaged with the elastic piece 130 of the fixture 100 described above. Since the resilient piece 130 engaged with the gear 200 has elasticity, a constant force is applied when the gear 200 is rotated forward or reverse. That is, the resilient piece 130 installed to mesh with the gear 200 functions to rotate the gear 200 by one click by the handle 300 to be described later.

Figure 5 shows a state in which the gear 200 is installed between the support block 110, one or two or more gears 200 in accordance with the interval between the support block 110 or the force adjustment for opening and closing one shaft Can be installed on Accordingly, the number of the elastic pieces can also be configured to be two or more.

The fixture 100 is coupled to the container body, but the handle 300 is connected to the cover and the appropriate combination between the handle, gear and fixture is required to secure the cover to the container body.

A locking rod 310 fitted to the locking groove 120 is connected to an upper side of the handle 300, and the handle 300 is coupled to the locking rod 310 to be rotated. And one end of the bracket (not shown) connected to the cover to the engaging rod 310 is connected. The inner surface of the handle 300 is formed with a restraining piece 320 to be engaged with the gear 200. When the handle 300 is rotated upward or downward, the gear 200 is restrained by the restraining piece 320. Is forcibly rotated. The restraining piece 320 which protrudes from the handle 300 and meshes with the gear 200 may have an appropriate shape according to the gear so that the gear 200 may be forcibly rotated.

3 is a view showing a state in which the lid is closed on the container body, and the restraining piece 320 of the handle 300 and the elastic piece 130 of the fixture 100 are engaged with the gear 200, respectively, and the handle 300. The restrained state between the gear and the handle and the gear and the elastic piece can be maintained unless the shaft is rotated upward.

That is, the cover opening and closing device according to the present invention is coupled to the restraint piece and the elastic piece on the same gear is double-constrained, so that the cover does not open unless an artificial force is applied to the handle and the cover forms a tightly sealed structure with the container body. do.

The operating principle of the cover opening and closing device having the configuration as described above will be briefly described.

When the cover is to be closed, first, the locking groove 120 formed in the fixture 100 is made to roughly coincide with the locking rod 310 to which the handle 300 and the cover are connected, and the handle 300 is downward. By rotating the restraining piece 320 formed on the handle meshes with the outer surface of the gear 200. When the restraining piece 320 is engaged with the gear 200, the handle 300 is further pushed downward, so that the gear together with the handle is rotated clockwise. When the handle 300 is rotated in the clockwise direction while being constrained with the gear 200, downward force is applied to the locking rod 310 to tightly fit the locking groove 120.

When the handle 300 is rotated in the clockwise direction, the elastic piece 130 engaged with the gear 200 simultaneously resists the rotation of the gear 200 with a constant force, and the gear is rotated by one click. Therefore, in order to cover the container body tightly coupled to the handle 300 must act more than the repulsive force generated by the engagement of the elastic piece 130 and the gear 200.

On the other hand, when the cover and the container body is combined to open the cover when the handle 300 is rotated counterclockwise, accordingly, the gear 200 is also rotated counterclockwise to act on the locking rod 310 The downward force is removed and the engagement of the restraint piece 320 of the handle 300 and the gear 200 is also released to open the cover.

The number of fasteners 100 may be varied depending on the size of the container body, the opening and closing device according to the present invention may be provided only on any one side of the container body, or may be installed on both sides facing each other. In the case where the opening and closing device according to the present invention is placed only on one side of the container body, the container body and the cover may be connected to the other side by using a general hinge means. When the opening and closing device according to the present invention is placed on both sides of the container body, one of the opening and closing device can be left open while the other opening and closing device is opened in one direction.

In the present invention, the opening and closing device of the cover opening and closing operation is made by the coupling operation of the handle and the restraint piece and the elastic piece engaging the gear can be kept constant the coupling force between the container body and the cover. Therefore, the closing force of the cover does not change even after frequent opening and closing, and in particular, it is possible to prevent damage to the sealing ribs (not shown) of the rubber material provided on the cover to maintain airtightness when the container body and the cover are combined. .

The cover opening and closing device according to the present invention has a constant force is applied when opening and closing the cover due to the interaction relationship between the restraint piece and the elastic piece engaging the gear, so that the performance does not easily fall even in the long-term use to supply products such as an ice cooler of excellent quality. It can be effective.

In addition, since the restraint piece and the elastic piece are dually engaged with the gear, the handle is not opened due to external impact, and thus, the handle is opened unexpectedly during movement, thereby preventing the inflow of outside air into the container.
