Abstract
Description
Technical Field
[0001] This utility model relates to the field of children's toy technology, and in particular to a stacking building block toy. Background Technology
[0002] In the existing technology, stacking building block toys include a first body and a second body. By splicing the first body and the second body, another shape can be achieved, thereby developing children's brain development. It has a good effect on children's education. Stacking building block toys on the market usually use a plug-in method to connect the first body and the second body. However, how to maintain the stability after splicing is quite critical. Moreover, the amount of plug insertion cannot be limited. When one side is over-inserted and the other side is only partially inserted, the stability is relatively poor. Furthermore, removing the plug later is also somewhat troublesome. Summary of the Invention
[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a stacking building block toy. By setting a tightening sleeve on the first body and the second body, when the first body and the second body are spliced, the pin tightens in the tightening sleeve, thereby preventing them from separating automatically. Furthermore, the displacement of the pin insertion is restricted by the limiting surface of the tightening sleeve, thereby preventing excessive insertion on one side.
[0004] This utility model discloses a stacking building block toy, including a first body, a second body, and a pin for connecting the first body and the second body. Both the first body and the second body are provided with insertion holes. One end of the pin is movably inserted into the insertion hole of the first body, and the other end is movably inserted into the insertion hole of the second body. The key feature is that: each of the insertion holes of the first body and the second body is provided with a tightening sleeve. The tightening sleeve is axially limited in the corresponding insertion hole. The tightening sleeve is also provided with a limiting surface for limiting the insertion displacement of the pin.
[0005] Using the above technical solution, the first and second bodies can be spliced by inserting a pin into the expansion sleeve. The pin can also be tightened with the expansion sleeve to prevent loosening. Furthermore, the axial sliding limit of the expansion sleeve can prevent the first and second bodies from automatically separating, making them more stable during use. The limiting surface can also prevent the pin from being inserted too much on one side.
[0006] A further feature of this invention is that the tightening sleeve includes two separately configured tightening sleeves, tightening sleeve I and tightening sleeve II. Tightening sleeve I is provided with a locking hook that can deform relative to each other, and tightening sleeve II is provided with a locking hole through which the locking hook can deform. Tightening sleeve I can be inserted from one side of the insertion hole, and tightening sleeve II can be inserted from the other side of the insertion hole. When the locking hook passes through the locking hole, it can hook onto the outer edge of the locking hole to form a lock.
[0007] The above technical solution uses a combination of a locking hook and a locking hole, which can be directly plugged in during assembly. It also has the effect of axial separation and limiting, making it more stable and effective in use. Furthermore, it adopts a split design, so if it is damaged, the locking hook can be deformed by external force, and then the expansion sleeve I and expansion sleeve II can be removed and replaced. If the first body and the second body are loose, the pin and the expansion sleeve can be replaced, without the need for complete replacement.
[0008] A further feature of this invention is that the expansion sleeve is provided with a flange for contact and limiting, and the insertion hole is provided with a limiting boss that abuts and limits the contact with the flange.
[0009] By adopting the above technical solution, the expansion sleeve can be prevented from slipping relative to each other by the cooperation of the flange and the limiting boss, making it more stable during use.
[0010] A further feature of this invention is that the outer wall of the pin is provided with several axially arranged protrusions, and the outward-facing side of the protrusions is provided with an inclined guide surface.
[0011] By adopting the above technical solution, the protrusion can be further tightened to prevent the first body and the second body from separating relative to each other, making it more stable during use.
[0012] A further feature of this invention is that the edges of the first and second bodies are chamfered.
[0013] By adopting the above technical solution, sharp corners are prevented, which further prevents children from bumping into them, resulting in a high safety factor. Attached Figure Description

[0020] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:
[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] This utility model discloses a stacking building block toy, including a first body 1, a second body 2, and a pin 3 for splicing the first body 1 and the second body 2 (the first body 1 is preferably rectangular, and the second body 2 is square, but it can also be triangular or other shapes). Both the first body 1 and the second body 2 are provided with insertion holes 4. One end of the pin 3 is movably inserted into the insertion hole 4 of the first body 1, and the other end is movably inserted into the insertion hole 4 of the second body 2. In this utility model embodiment, both the first body 1 and the second body 2 are provided with expansion sleeves 5. The expansion sleeves 5 are axially limited in the corresponding insertion holes 4. The expansion sleeves 5 are also provided with limiting surfaces 6 for limiting the insertion displacement of the pin 3 (preferably, the pin 3 is provided with a boss, and the boss cooperates with the limiting surface 6 to achieve limiting).
[0023] Using the above technical solution, when in use, the first body 1 and the second body 2 can be spliced by inserting the pin 3 into the expansion sleeve 5. The pin 3 can be tightened with the expansion sleeve 5 to prevent loosening. Furthermore, the axial sliding limit of the expansion sleeve 5 can prevent the first body 1 and the second body 2 from automatically separating, making it more stable during use. In addition, the limiting surface can prevent the pin 3 from being inserted too much on one side.
[0024] The tightening sleeve 5 includes two separately configured tightening sleeves, I51 and II52. Tightening sleeve I51 has a relatively deformable locking hook 511, and tightening sleeve II52 has a locking hole 521 through which the locking hook 511 can deform and pass. Tightening sleeve I51 can be inserted from one side of the insertion hole 4, and tightening sleeve II52 can be inserted from the other side of the insertion hole 4. When the locking hook 511 passes through the locking hole 521, it hooks onto the outer edge of the locking hole 521 to form a lock. This is achieved through the optimal cooperation of the locking hook 511 and the locking hole 521. The lock hole 521 has an extended outer edge, and the lock hook 511 is hooked on the extended outer edge. It can be directly plugged in during assembly and can also play an axial separation and limiting role. It is more stable and effective in use. It adopts a split design. When it is damaged, the lock hook 511 can be deformed by external force, and then the expansion sleeve I 51 and expansion sleeve II 52 can be removed and replaced. When the first body 1 and the second body 2 are loosely connected, the pin 3 and expansion sleeve 5 can be replaced. It is not necessary to replace the whole body.
[0025] The expansion sleeve 5 is also provided with a flange 7 for abutting and limiting, and the insertion hole 4 is provided with a limiting boss 8 that abuts and limits the flange 7. By cooperating with the flange 7 and the limiting boss 8, the expansion sleeve 5 can be prevented from sliding relative to each other, making it more stable during use.
[0026] The outer wall of the pin 3 is also provided with a number of axially arranged protrusions 9. The outward side of the protrusions 9 is provided with an inclined guide surface 91. The protrusions 9 can be further tightened to prevent the first body 1 and the second body 2 from separating relative to each other, making them more stable during use.
[0027] The chamfered edges of the first body 1 and the second body 2 prevent sharp corners and further prevent children from bumping into them, resulting in a high safety factor.
