Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] With reference to Figures 1 - 6 , the present utility model provides a push-pull metal packaging box, which includes a metal box body 1 and a box cover 2. A rectangular sealing gasket 3 is fixedly connected to the inner side of the box cover 2. The rectangular sealing gasket 3 is used to seal the connection between the metal box body 1 and the box cover 2. Fixed support rods 4 are fixedly connected to both sides of one end of the box cover 2, and a round slider 41 is fixedly connected to one end of the fixed support rod 4. A push-pull groove 5 for the round slider 41 to slide is formed on the side surface of the metal box body 1. The push-pull groove 5 is composed of a horizontal groove and an inclined groove connected. The push-pull groove 5 composed of the horizontal groove and the inclined groove connected can provide a path with a height difference for the round slider 41, so as to improve the covering position of the box cover 2 on the metal box body 1. Fixed shells 6 are fixedly connected to both sides of the metal box body 1, and an elastic limit structure 7 for elastically clamping the round slider 41 is arranged in the fixed shell 6. The elastic limit structure 7 is arranged on the inclined groove side of the push-pull groove 5. A handle rod 8 is rotatably connected to one end of the box cover 2 in a damped manner. The handle rod 8 can be rotatably connected to the box cover 2 through a damped rotating shaft. The handle rod 8 can be used to pull and push the box cover 2 for use.

[0023] The size of the rectangular sealing gasket 3 is adapted to the size of the metal box body 1. The rectangular sealing gasket 3 is in close contact with the metal box body 1. The rectangular sealing gasket 3 can be used to increase the sealing performance of the inner cavity of the metal box body 1, so as to achieve sealing effects such as dust prevention and waterproofing.

[0024] The elastic limit structure 7 includes a clamping seat 71, a pair of telescopic rods 72 fixedly connected to the clamping seat 71, and a tension spring 73 sleeved on each telescopic rod 72. One end of the telescopic rod 72 facing away from the clamping seat 71 is fixedly connected to the inner wall of the fixed shell 6. In this application, a pair of elastic limit structures 7 are arranged in the fixed shell 6, and the pair of elastic limit structures 7 are mirror-symmetrically distributed above and below the circular slider 41.

[0025] The clamping seat 71 is provided with an inclined sliding surface 10 slidably connected to the circular slider 41, and the clamping seat 71 is further provided with an arc-shaped clamping groove 11 clamped to the circular slider 41. The inclined sliding surface 10 and the arc-shaped clamping groove 11 arranged on the clamping seat 71 are connected by chamfering.

[0026] Specifically, when the circular slider 41 slides in the transverse groove of the push-pull groove 5, at this time, the rectangular gasket 3 on the box cover 2 is not in close contact with the metal box body 1. Until the circular slider 41 slides to the end of the inclined groove, at this time, the box cover 2 can descend on the metal box body 1 until the rectangular gasket 3 on the box cover 2 is pressed tightly on the metal box body 1. During this process, the circular slider 41 can squeeze the inclined sliding surface 10 of the clamping seat 71. At this time, the telescopic rod 72 can provide compression guidance for the tension spring 73 until the circular slider 41 enters the arc-shaped clamping groove 11 at the chamfer of the inclined sliding surface 10. Using the elastic force of the tension spring 73, a pair of clamping seats 71 arranged up and down can clamp on the circular slider 41, so as to reduce the anti-disconnection property of the box cover 2.

[0027] It should be noted that since the arc-shaped clamping groove 11 of the clamping seat 71 partially covers the circular slider 41, when an external force acts on the box cover 2 to move to one side, the circular slider 41 can push the clamping seat 71 and break away, so as to meet the detachable property of the box cover 2.

[0028] A stopper 9 is arranged in the transverse groove of the push-pull groove 5. A rubber plug 91 is fixedly connected to the stopper 9. The rubber plug 91 is in interference connection with the inner wall of the transverse groove of the push-pull groove 5. In this application, a slot for the interference connection of the rubber plug 91 is arranged in the push-pull groove 5, so as to meet the convenience of detaching the stopper 9. Then, by flexibly arranging the stopper 9 in the push-pull groove 5, it is convenient to take out the box cover 2 together with the circular slider 41.

[0029] One end of the metal box body 1 is fixedly connected with a limit seat 12. An anti-slip pad 121 is fixedly connected to the inner side of the limit seat 12. The anti-slip pad 121 is arranged in a "U" shape. In this application, the anti-slip pad 121 is made of rubber material. At the same time, the inner size of the anti-slip pad 121 is smaller than the width size of the handle rod 8. The handle rod 8 arranged on the box cover 2 is in close contact with the inside of the anti-slip pad 121. In this application, under the condition that the handle rod 8 meets the use of the hand-held part for pushing and pulling the box cover 2, the connection with the damping rotation of the handle rod 8 is used to reduce the flexibility of free swing. The handle rod 8 is inserted and matched with the anti-slip pad 121 with a size smaller than it, so that the placement position of the handle rod 8 can be limited in the vertical direction. In this way, the limit seat 12 can prevent the box cover 2 from moving horizontally to meet the further locking effect of the push-pull box cover 2, and the closing stability is high.
