Description

Technical Field

[0001] The utility model relates to a powder bin structure which is airtight and convenient for adding powder. Background Art

[0002] The existing powder silo is designed to facilitate users to add carbon powder by themselves at a later stage so as to realize the recycling of the powder silo. A powder adding port is set on the side wall of the powder silo, and a sealing plug is inserted into the powder adding port. The sealing plug is constrained to remain in the powder adding port through interference fit between the sealing plug and the powder adding port. Under normal circumstances, the sealing plug will not detach from the powder adding port. However, in environments such as transportation, the bumps in the powder silo can easily cause the sealing plug to loosen, causing it to fall off, and eventually lead to powder leakage. For this reason, the existing powder silo structure needs to be further improved. Utility Model Content

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] See also Figure 1-Figure 6A powder bin structure that is airtight and convenient for adding powder comprises a powder bin 10, wherein a powder adding port 110 is arranged on one side of the powder bin 10, wherein a convex ring 120 protruding outward is arranged at the powder adding port 110, wherein a sealing plug 20 for sealing the powder adding port 110 is inserted into the convex ring 120, wherein a limiting knob 210 is arranged at one end of the sealing plug 20 facing outward, wherein at least one limiting groove 130 is arranged on the convex ring 120, wherein the limiting groove 130 comprises an entry section 132, a connecting section 131 and a locking section 133 which are connected in sequence, and wherein the front end of the entry section 132 passes through the convex ring 120 and is arranged to be open;

[0022] The sealing plug 20 is provided with a locking column 40 which can be inserted into the locking section 133 through the entry section 132 and the connecting section 131;

[0023] The rear end of the locking section 133 is connected to the connecting section 131 and the front end of the locking section 133 is closed;

[0024] An elastic component 30 is sleeved on the sealing plug 20 between the locking column 40 and the limiting knob 210 . The elastic component 30 is used to apply a force to the limiting knob 210 to keep the locking column 40 at the front end of the locking section 133 .

[0025] The utility model maintains the locking column at the front end of the locking section through the cooperation between the locking column and the limiting groove, which can effectively restrict the sealing plug from moving forward relative to the convex ring, thereby avoiding the problem of the sealing plug falling off, and effectively solving the problem of the sealing plug falling off due to shaking in the prior art, causing powder leakage.

[0026] During assembly, the elastic component 30 is first sleeved onto the sealing plug 20 at the rear side of the limit knob 210, and then the locking column 40 is assembled with the sealing plug 20. During assembly, the locking column 40 needs to be installed on the sealing plug 20 at the rear side of the elastic component 30. After the parts are assembled, the sealing plug 20 and the convex ring 120 can be inserted into each other, and the two are interference-fitted to achieve sealing. During the insertion, the sealing plug 20 gradually moves toward the rear side relative to the convex ring 120. During this process, the locking column 40 is gradually inserted into the entry section 132 until the locking column 40 reaches the rear end of the entry end 132. During this process, the elastic component 30 is compressed to store force, and then the limit knob 210 is rotated to drive the sealing plug 20 and the locking column 40 to rotate together, so that the connecting section 131 of the locking column 40 intersects with the locking section 133, that is, the rear end of the locking section 133. At this time, by releasing the limit knob 210, there is no restraining force, and the elastic component 30 releases the stored force, which can drive the sealing plug 20 and the locking column 40 to move forward, even if the locking column 40 enters the front end of the locking section 133 to complete the locking.

[0027] In the utility model, the sealing plug 20 is provided with a threaded hole 220, and the locking column 40 is threadedly connected in the threaded hole 220. The structure is simple, the assembly is convenient, and it meets the use requirements.

[0028] See also Figure 2 The elastic component 30 includes a first fitting ring 310, a spring 320 and a second fitting ring 330 which are connected in sequence. The first fitting ring 310 fits with the rear end surface of the limit knob 210, and the second fitting ring 330 fits with the front end surface of the convex ring 120.

[0029] In the present invention, the entry section 132 and the locking section 133 are arranged parallel to each other; the entry section 132 and the connecting section 131 are arranged perpendicular to each other.

[0030] In the present invention, a powder feeding roller 50 and a powder stirring roller 60 are rotatably arranged in the powder bin 10. The powder feeding roller 50 is a screw, and its function is to transport the toner to the powder outlet 100 during the rotation process for use by the printer.
