DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown:

[0021] Embodiment 1: The utility model provides a tender document storage device, comprising: a storage mechanism 1, comprising a storage box assembly 11, a storage box assembly 12 slidably embedded in the storage box assembly 11, and a control panel 13 arranged on the outside of the storage box assembly 11; a lifting mechanism 2, comprising a driving assembly 21 installed on the outside of the storage box assembly 11, a sliding frame assembly 22 arranged on the driving assembly 21, and a guide frame 23 fixedly installed on the outside of the storage box assembly 11, the sliding frame assembly 22 is slidably embedded on the guide frame 23, and the movement of the sliding frame assembly 22 can drive the storage box assembly 12 to be stored in the storage box assembly 11;

[0022] Among them, the driving component 21 is operated through the control panel 13, and the operation of the driving component 21 will cause the sliding frame component 22 to move upward. The upward movement of the sliding frame component 22 will drive the storage box component 12 to be stored in the storage box component 11, thereby completing the storage and facilitating the operation of the staff. The control panel 13 is controlled to make the sliding frame component 22 move downward. After the sliding frame component 22 moves downward, the storage box component 12 will automatically reset and extend out of the storage box component 11, thereby facilitating the staff to take and put files.

[0023] Specifically, the storage box assembly 11 includes a storage box body 111, a plurality of guide rods 112 are fixedly connected to the interior of the storage box body 111, a guide groove 113 is also opened on the front side of the storage box body 111, and a fixing block 114 and a fixing block 2 115 are fixedly connected to the outside of the storage box body 111.

[0024] Specifically, the storage box assembly 12 includes a guide slider 121 , the upper side of the guide slider 121 is fixedly connected to a storage box body 122 , and the rear side of the guide slider 121 is also fixedly connected to a spring 123 .

[0025] Specifically, the guide slider 121 and the spring 123 are both limitedly slidably embedded on the guide rod 112 , and the spring 123 drives the guide slider 121 to extend out of the storage box body 111 .

[0026] As can be seen from the above, when the connecting rod 222 no longer drives the storage box body 122, the spring 123 resets to move the guide slider 121 along the guide rod 112, so that the storage box body 122 extends out of the storage box body 111, making it convenient for staff to take and put bid documents.

[0027] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the driving assembly 21 includes a motor 211 and a screw rod 212, the output end of the motor 211 is fixedly connected to a gear 1 213, and one end of the screw rod 212 is fixedly connected to a gear 2 214; the sliding frame assembly 22 includes a slider 221, and one end of the slider 221 is fixedly connected to a connecting rod 222.

[0028] Specifically, the motor 211 is fixedly mounted on the fixed block 114, the screw rod 212 is mounted on the fixed block 114 through a bearing, the gear 1 213 and the gear 2 214 are meshed with each other, the connecting rod 222 is limitedly slidably embedded in the guide frame 23, and the rotation of the screw rod 212 can drive the slider 221 to move up and down.

[0029] As can be seen from the above, controlling the operation of the motor 211 can cause the gear 1 213 to rotate, the rotation of the gear 1 213 can cause the gear 2 214 to rotate, the rotation of the gear 2 214 can cause the screw rod 212 to rotate on the fixed block 1 114, the rotation of the screw rod 212 can cause the slider 221 to move on the connecting rod 222, the movement of the connecting rod 222 can cause the storage box body 122 to drive the guide slider 121 to move and be stored in the storage box body 111, and the guide frame 23 can play a guiding role when the connecting rod 222 moves.
