The tray can be assembled and can be reused, so that the cost is saved and the waste is avoided.

In some embodiments, the first baffle 120 may be a circular baffle having a center located on the axis of the first bobbin 110. The second baffle 220 may be a circular baffle having a center located on the axis of the second bobbin 210. In addition, the first and second baffles 120 and 220 may be the same size so that the first and second baffles 120 and 220 face each other after the first and second trays 100 and 200 are assembled.

The specific structure of the first bobbin 110 and the second bobbin 210 in the embodiment of the present disclosure will be described in detail with reference to fig. 2 and 3. As shown in fig. 2, the first bobbin 110 includes: a first boss 111 and a first ring member 112. One axial end of the first boss 111 is fixedly connected to the first baffle 120. The first boss 111 may be a cylindrical boss to facilitate subsequent printing wire to be wound on the first boss 111, and an axis of the first boss 111 may be the same as an axis of the first bobbin 110 as a whole. The first ring member 112 is disposed on an end surface of the first boss 111 facing away from the first baffle 120, and an annular center of the first ring member 112 is located on an axis of the first boss 111, so it can be understood that the first baffle 120, the first boss 111, and the first ring member 112 are concentrically disposed. The annular radius of the first ring member 112 may be smaller than the radius of the cross section of the first boss 111. The first ring member 112 is also protruded in the axial direction of the first bobbin 110 to have a certain height. At least one stopper 113 is provided on the circumferential outer surface of the first ring member 112. In some embodiments, in order to stabilize the structure of the assembled tray, a plurality of position-limiting strips 113 may be provided, and the plurality of position-limiting strips 113 are uniformly arranged on the circumferential outer surface of the first annular component 112 at equal intervals. In the embodiment shown in fig. 2, the number of the stopper bars 113 is 3.

As shown in fig. 3, the second bobbin 210 includes: a second boss 211 and a second annular member 212. One end of the second boss 211 is fixedly connected to the second baffle 220. The second boss 211 may be a cylindrical boss to facilitate a subsequent printing wire to be wound on the second boss 211, and an axis of the second boss 211 may be the same as an overall axis of the second bobbin 210. Second ring member 212 is disposed on an end surface of second boss 211 facing away from second baffle 220, and the annular center of second ring member 212 is located on the axis of second boss 211, so it can be understood that second baffle 220, second boss 211, and second ring member 212 are concentrically disposed. The second ring member 212 is protruded in an axial direction of the second bobbin 210 to have a certain height, and at least one catching groove 214 is formed on a circumferential inner surface of the second ring member 212. as shown in fig. 3, a bar-shaped protrusion may be provided on the circumferential inner surface of the second ring member 212, the bar-shaped protrusion and the second ring member 212 together forming the catching groove 214, and the circumferential inner surface of the second ring member 212 constitutes a bottom surface of the catching groove 214. The caliber of the second ring-shaped element 212 is larger than that of the first ring-shaped element 112, so that when the first disc body 100 and the second disc body 200 are connected and installed, the first ring-shaped element 112 can enter the ring of the second ring-shaped element 212, and therefore the combination of the limiting strip 113 and the limiting groove 214 is realized.

As shown in fig. 3, the axial first end of the second bobbin 210 is further provided with a limiting component 215, and the limiting component 215 is located at one side of one limiting groove 214 of the at least one limiting groove 214 in the circumferential direction of the second bobbin 210. As shown in fig. 4, the position limiting assembly 215 includes: a resilient member 2151 and a stop member 2152. The elastic member 2151 is disposed along a radial extension of the second bobbin 210, and the elastic member 2151 includes one end connected to the second bobbin 210 and an opposite free end. The stopper 2152 is fixedly disposed on a free end of the elastic member 2151, and is configured to be movable toward an axis of the second bobbin 210 in a radial direction of the second bobbin 210 by an elastic force of the elastic member 2151. When the elastic member 2151 is at a free length (i.e., is not subject to any external force), at least a portion of the surface of the stopper 2152 facing the axis of the second bobbin 210 is located at a first position in the radial direction of the second bobbin 210, wherein the inner surface of the bottom of the spacing groove 214 is located at a second position in the radial direction of the second bobbin 210, the first position being closer to the axis of the second bobbin 210 than the second position, so that the stopper 2152 restricts the rotation of the spacing bar 113 out of the spacing groove 214 when the spacing bar 113 is rotated into the corresponding spacing groove 214. In the embodiment shown in fig. 3, the number of the spacing grooves 214 is 3, and each of the spacing grooves 214 is formed in a set with a corresponding one of the spacing bars 113 and is configured to receive the corresponding one of the spacing bars 113.

Referring to fig. 4, the working principle of the tray of the embodiment of the present disclosure is that when the first tray body 100 and the second tray body 200 are assembled, the side view thereof is as shown in fig. 4, wherein the spacing bars 113 have entered the corresponding spacing grooves 214, the outwardly convex surfaces of the spacing bars 113 are in contact with the bottom surfaces of the spacing grooves 214 (the spacing grooves 214 are shown in fig. 4 as being inverted, so that the bottom surfaces thereof are actually at the top). Since the elastic member 2151 is at the free length, the surface of the stopper 2152 facing the axis of the second bobbin 210 is at a first position lower than the surface of the bottom of the spacing groove 214, so that the stopper 2152 can block the spacing bar 113 from being rotated out of the side outlet of the spacing groove 214. In this state, the first tray 100 and the second tray 200 are connected and cannot move relative to each other. When it is required to disassemble the first and second disks 100 and 200, the stopper 2152 may be pushed outward in the radial direction of the second spool 210 such that the surface of the stopper 2152 facing the axis of the second spool 210 is higher than the surface of the bottom of the stopper groove 214, i.e., farther from the axis in the radial direction of the second spool 210 than the second position. At this time, the limiting bar 113 may be unscrewed from the outlet of one side of the limiting groove 214, and at this time, the first tray 100 and the second tray 200 may be detached. When the tray needs to be assembled again, the first bobbin 110 and the second bobbin 210 can be butted first, and the limiting bar 113 is positioned below the stopping member 2152, and the elastic member 2151 is in a compressed state. Then, the first tray body 100 is rotated relative to the second tray body 200 in a clockwise direction in fig. 4 so that each stopper bar 113 is screwed into the corresponding stopper groove 214, and finally reaches a state shown in fig. 4, when the stopper bar 113 completely enters the corresponding stopper groove 214, the stopper 2152 falls down, and the elastic member 2151 is restored to the free length again.

In some embodiments, the second bobbin 210 further includes: and a third ring member 213. A third ring member 213 is disposed on an end surface of second boss 211 facing away from second baffle 220, third ring member 213 is located outside of second ring member 212 and may be disposed concentrically with second ring member 212, and an annular space between second ring member 212 and third ring member 213 may be used to receive spacing assembly 215. As shown in fig. 3, one end of the elastic member 2151 is connected to the circumferential inner side of the third ring member 213. An open section may also be provided on the second ring 212 to allow passage of the stop 2152.

In some embodiments, as shown in fig. 2, the first bobbin 110 further includes: a plurality of arcuate ribs 114. A plurality of arc-shaped convex strips 114 are arranged on the end face of the first boss 111 facing away from the first baffle 120 and outside the first ring member 112, and the arc-shaped convex strips 114 are formed on a circumference concentric with the first ring member 112. The plurality of arc-shaped convex strips 114 are arranged to abut against the circumferential inner side of the third ring member 213 to restrict the mutual movement between the first disc 100 and the second disc 200.

In some embodiments, the stopper 2152 is disposed along a circumferential extension of the second bobbin 210, and the stopper 2152 is an elongated sheet structure having a first extension 2152a and a second extension 2152 b. The first extension 2152a is closer to a corresponding one of the at least one catching groove 214 than the second extension 2152b is to the at least one catching groove 214 in the circumferential direction of the second bobbin 210. When the elastic member 2151 is at the free length, the circumferential surface of the first extension portion 2152a facing the axis of the second spool 210 is located at a first position. As shown in fig. 4, the lower surface (i.e., the circumferential surface facing the axis of the second bobbin 210) of the first extension 2152a is located at a first position closer to the axis of the second bobbin 210 than a second position so that the stopper 2152 blocks the stopper bar 113.

In some embodiments, the circumferential surface of the second extension 2152b facing the axis of the second bobbin 210 is located at a third position in the radial direction of the second bobbin 210, the first position being closer to the axis of the second bobbin 210 than the third position. As shown in fig. 4, a lower surface of the second extension 2152b (i.e., a surface facing the axis of the second bobbin 210) is farther from the axis of the second bobbin 210 than a lower surface of the first extension 2152 a. This arrangement facilitates entry of the stop bar 113 under the stopper 2152 when the first and second trays 100 and 200 are assembled, and particularly, the third position may be further away from the axis of the second spool 210 than the second position, so that the stop bar 113 can be brought under the second extension 2152b of the stopper 2152 without interference from the stopper 2152 without any manual operation (e.g., pushing the stopper 2152 radially outward). In addition, the lower surfaces of the first and second extensions 2152a and 2152b may be generally arcuate, i.e., the lower surfaces may have a gradual section as they extend generally from the third position to the first position. In the subsequent assembly process, the first tray 100 may be rotated relative to the second tray 200 (the first tray 100 is rotated clockwise as shown in fig. 4), and during the rotation process, the limiting bar 113 may push the blocking member 2152 upward and finally enter the corresponding limiting groove 214.
