As shown in fig. 1 to 5, this embodiment describes a pencil lead box, which includes a housing 1 and a dial 2. The housing 1 is internally provided with a storage cavity 100 for storing pencil cores and a core outlet channel 101 communicated with the storage cavity 100 and used for discharging pencil cores. The sliding cavity 102 is arranged in the shell 1 beside the core outlet channel 101, and the shifting block 2 is movably arranged in the sliding cavity 102 and can at least partially extend into the core outlet channel 101 to cut off or open the core outlet channel 101. The shell 1 comprises a first shell 11 and a second shell 12 which is fixedly connected to the side surface of the first shell 11 in a covering manner. The second housing 12 is configured as a U-shaped housing 1, and the U-shaped housing 1 includes an end wall 121 for covering one side of the storage chamber 100, the core-out channel 101 and the sliding chamber 102, and side walls 122 disposed on both sides of the end wall 121, and a clamping strip 123 is disposed on an outer end portion of an inner wall of the side walls 122. A clamping groove corresponding to the clamping strip 123 is formed in the end corner of the rear side face of the first shell 11. When the first housing 11 and the second housing 12 are fixedly connected, the side walls 122 on both sides of the second housing 12 are coated on both sides of the first housing 11, and the clamping strips 123 are clamped into the clamping grooves.

The storage cavity 100 in the pencil lead box is used for storing pencil leads, the pencil leads can be taken out from the core outlet channel 101, and at least part of the poking block 2 arranged in the sliding cavity 102 can extend into the core outlet channel 101 to cut off or open the core outlet channel 101, namely, the switch control of the core outlet channel 101 is realized. The width of the core outlet channel 101 is 1.5-3.25mm, so that a large amount of pencil cores are prevented from being poured out of the box body at the same time.

In this embodiment, the first housing 11 and/or the second housing 12 are/is configured with a gear slot 13 on the bottom surface and/or the top surface of the sliding cavity 102 for positioning the shifting block 2, and a positioning block 21 matched with the gear slot 13 is configured on the top surface and/or the bottom surface of the shifting block 2. When the shifting block 2 is movably arranged in the sliding cavity 102, the shifting block is positioned based on the fact that the sliding cavity 102 is clamped into the gear groove 13. The housing 1 in this embodiment is still connected by the first housing 11 and the second housing 12 in a covering manner, while the gear groove 13 for positioning the shift block 2 is formed on the bottom and/or top surface of the sliding chamber 102 of the first housing 11 and/or the second housing 12. Correspondingly, the positioning blocks 21 on the shifting block 2 are also arranged on the top surface and/or the bottom surface of the shifting block 2. Based on this scheme, when external force pushes the shifting block 2 to move along the sliding cavity 102, the positioning block 21 will not push the first housing 11 and the second housing 12 apart in the process of moving relative to the gear slot 13. On the basis of realizing the positioning of the shifting block 2, the technical problem that the shell 1 described in the background art is jacked up is solved.

As shown in fig. 3, through holes 103 are formed in the first housing 11 and/or the second housing 12 at two sides of the sliding cavity 102, and the toggle parts 22 extending out of the side surfaces of the first housing 11 and/or the second housing 12 from the through holes 103 are formed at two sides of the toggle block 2. The through hole 103 in this embodiment may be provided separately on the first housing 11 or the second housing 12, or may be provided simultaneously. Likewise, the toggle portion 22 on the toggle block 2 may be provided on both sides or on one side. In this case, the toggle portion 22 extends from the through hole 103 to the side wall 122 of the housing 1, so as to facilitate the force application of the hand of the user, i.e. to be used as the force application end for the user to toggle.

As shown in fig. 3, the sliding cavity 102 is communicated with the core outlet channel 101 through a blocking opening 104, and a blocking tongue 23 is arranged at a position of the shifting block 2 corresponding to the blocking opening 104. When the shifting block 2 is movably arranged in the sliding cavity 102, the blocking tongue 23 enters or exits the core-out channel 101 through the blocking opening 104. In a specific scheme, the first housing 11 and/or the second housing 12 are respectively formed with an inner limiting portion 14 and an outer limiting portion 15 at front and rear sides of the sliding cavity 102, and the dial 2 is located in the sliding cavity 102 between the inner limiting portion 14 and the outer limiting portion 15. The blocking opening 104 is formed on the inner limiting portion 14. The outer limiting part 15 is provided with an outer opening 105 for the outer end part of the shifting block 2 to extend. The outer opening 105 here acts to allow the outer end portion of the dial 2 to protrude, thereby increasing the path of movement of the dial 2. And when the shifting block 2 needs to be pushed in, the force is saved by the way of pressing the outer end part.

In a specific embodiment, the first housing 11 and/or the second housing 12 are provided with rail walls 16 on both upper and lower sides of the sliding chamber 102, and the gear groove 13 is formed on the rail walls 16 on the upper and/or lower sides. When the shifting block 2 is installed in the sliding cavity 102, the top surface and the bottom surface of the shifting block 2 are slidably positioned with the rail wall surfaces 16 on the upper side and the lower side of the shifting block 2. That is, as described above, the movement direction of the dial 2 is restricted by the rail wall surfaces 16 on the upper and lower sides after the dial 2 is placed in the slide chamber 102, and the rail wall surface 16 on the lower side also serves as a shoe. Further, the rail wall surface 16 is formed with a plurality of gear grooves 13, and the groove side walls 122 of the gear grooves 13 are formed as inclined surfaces or cambered surfaces having guiding function. The positioning block 21 on the shifting block 2 is constructed as an arc-shaped protrusion or a triangular protrusion having a guiding function. Based on the sliding fit of the groove side wall of the gear groove 13 and the positioning block 21, the positioning block 21 and the gear groove 13 can be clamped in and out when the shifting block 2 is transversely pulled, so that the positioning is convenient.

In the description of the present specification, a description referring to terms "one embodiment," "some embodiments," "examples," "specific examples," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present utility model.
