Abstract
The utility model relates to the field of daily supplies, in particular to a chart drum insertion device. The chart drum insertion device comprises a base and an insertion rod; the insertion rod is of a hollow structure and is provided with an end cover at the top end; the diameter of the end cover is greater than that of the insertion rod; a gasket is arranged in the bottom end of the insertion rod; a screw hole is formed in the center of the gasket; a bolt is vertically upwards arranged in the center of the base; the bolt and the screw hole are matched; the gasket is provided with a round bottom wall, and a side wall downwards extends along the circumference of the round bottom wall, so the gasket is drum-like; a screw hole is formed in the center of the round bottom wall; the side wall of the gasket and the side wall of the bottom of the insertion rod are fixedly connected by spot welding. According to the chart drum insertion device, the insertion rod and the base are of a split structure, the end cover is arranged at the top of the insertion rod, the diameter of the end cover is greater than that of the insertion rod, after being mounted, roll paper is locked in the insertion rod, the condition that the roll paper is drawn out during use is avoided, and the user performance is improved.
Description
Technical field
The utility model relates to daily life product field, and especially a kind of chart drum is inserted.
Background technology
Inserted link and base that existing chart drum is slotting are all structure as a whole, and above coil paper is directly set in, in the time using extraction, because the top of inserted link does not have latch-up structure, coil paper is easily extracted out from inserted link, affects the normal use of coil paper.
Utility model content
The purpose of this utility model is the deficiency in order to solve above-mentioned technology and provide a kind of split type and chart drum that serviceability is superior to insert.
In order to achieve the above object, the designed chart drum of the utility model is inserted, and it comprises base and inserted link, inserted link is hollow-core construction, and top is provided with end cap, and the diameter of end cap is greater than the diameter of inserted link, inside, bottom at inserted link is provided with pad, is provided with screw at the center of pad; Center at base is provided with bolt straight up, and bolt coordinates with screw.
As optimization, described pad is for having a circular bottom wall, and circular bottom wall has sidewall along circumferential downward-extension, makes pad be cylindrical body, and center in circular bottom wall is provided with screw.In the time of assembling, the sidewall of pad is fixedly connected with by spot welding with the sidewall of inserted link bottom, can avoid pad generation deflection, thereby the situation that can avoid the screw on pad to be difficult to coordinate with the bolt on base, improve efficiency of assembling and production efficiency, and the sidewall of pad there is larger area to provide electric welding to fix, can reduce the thickness of pad, thereby can reduce the loss of material, increase economic efficiency.
The chart drum that the utility model obtains is inserted, and its inserted link and base are Split type structure, and are provided with end cap at the top of inserted link, the diameter of end cap is greater than the diameter of inserted link, after coil paper installation, is locked in inserted link, avoid situation about being drawn out of while use, improved serviceability.
