Description

Technical Field

[0001] The utility model relates to the technical field of toys, and more specifically, to a building block connection component and a toy building block set. Background Art

[0002] The mortise and tenon structure is the most commonly used structure in toy building block sets. It uses the way of mutual engagement between the tenon and the mortise to tightly connect two building block components together, making the overall structure of the spliced object more stable. Moreover, the mortise and tenon connection can also provide more combination options for the building block components, increasing the diversity of the styles of the spliced object.

[0003] Currently, most toy building block sets contain connecting pieces, which are used to connect two or more other independent building block components, thereby changing the positional relationship of the connected building block components and maintaining the adjusted position. For example, the building block connecting piece disclosed in the Chinese patent with the publication number CN219462498U and the patent name "A Building Block Connecting Piece" includes a main body part. A convex first connecting part is provided on the front side of the main body part, and a first concave position is provided on the opposite rear side. The first connecting part and the first concave position are in concave-convex matching. A second connecting part is provided on the top of the main body part, and a second concave position is provided on the opposite bottom. The second connecting part and the second concave position are in concave-convex matching. Third connecting parts are provided on both sides of the main body part, and the third connecting parts include connecting platforms with different sizes.

[0004] Through the first connecting part, the second connecting part provided on the main body part and the connecting platforms with different sizes on the third connecting part, the above-mentioned building block connecting piece enables other building block components to be spliced in different directions. However, after other building block components are spliced with it, the angles between the spliced building block components always remain fixed, and the change of the angle cannot be realized, thus affecting the diversity of the final shape of the spliced object.

[0005] In this regard, the building block connecting piece disclosed in the Chinese patent with the publication number CN218553120U and the patent name "A Building Block Connecting Piece with Adjustable Angle" can combine adjacent building block bottom plates into a three-dimensional structure to form a three-dimensional building block bottom plate, and can adjust the angle so that different angles can be presented after two adjacent building block bottom plates are joined together. However, this connecting piece can only be used as a joint during the splicing process. After connecting the building block bottom plates, it cannot be positioned by itself, so it is difficult to be applied in toy building block sets such as toy track plates that require the spliced object to maintain a stable structure, restricting the types of spliced objects that it can splice. Summary of the Utility Model

[0006] In view of the above situation, in order to overcome the problem that some connecting pieces in the existing toy building block sets cannot change the relative angles of the connected building block components, and some connecting pieces can only be used as joint pieces and cannot be positioned by themselves, making it difficult to be applied in toy building block sets such as toy track boards that require the spliced objects to maintain a stable structure, the purpose of the present utility model is to provide a building block connection component and its toy building block set whose own angle can be changed, so that the angles of the connected building block components can be adjusted accordingly, and can be spliced and fixed with other building blocks to keep the connected building block components in a stable position, and thus the types of spliced objects that can be spliced are more diverse and have a wider range of applications.

[0007] In order to achieve the above purpose, the technical solution of the present utility model is as follows:

[0008] A building block connection component, which includes a connecting piece and a base. The connecting piece is rotatably connected to the base. At least one mortise is provided on the base for mating with the tenons of other building block components of the configured toy building block set. The connecting piece has two opposite and spaced wings.

[0009] Preferably, the connecting piece has at least two connecting heads adapted to the slots on other building block components of the configured toy building block set.

[0010] Preferably, the connecting head includes a connecting arm and a pawl. The pawls are formed on two opposite sides of the connecting arm. The free ends of the pawls are bent towards the same side wall of the connecting arm, and a buffer groove is formed between the pawls and the connecting arm.

[0011] Preferably, a rotating hole communicating with any one of the mortises is provided on the base. The connecting piece has a rotating rod. The connecting piece is rotatably connected to the base by inserting the rotating rod into the rotating hole.

[0012] Preferably, a limiting flange is formed on the outer peripheral wall of the rotating rod, and the limiting flange cooperates with the step at the transition position of the rotating hole and the mortise.

[0013] Preferably, an inserting tube is formed at the transition position of the rotating hole and the mortise. The inner diameter of the inserting tube decreases from the direction of the rotating hole to the mortise, and a partition groove is provided on the peripheral side wall of the inserting tube along its length direction. The shape of the rotating rod matches the inner tube section of the inserting tube, and the limiting flange cooperates with the bottom step of the inserting tube.

[0014] A toy building block set having the above building block connection component further includes a plurality of track boards and building blocks. The slots are located at the ends of each track board. The building blocks have at least one tenon and mortise.

[0015] Preferably, each track board forms two spaced cross beams. The cross beams include an outer beam and an inner beam in sequence from outside to inside. The height of the outer beam is greater than that of the inner beam, so that a step position is formed between the outer beam and the inner beam.

[0016] Compared with the prior art, the advantages of the utility model are as follows:

[0017] The building block connection component of the utility model utilizes the rotation of the connecting piece around the docking position with the base to drive the connected building block components to adjust the angle. Moreover, when a building block component is connected to the connecting head of the connecting piece, the base can also participate in the splicing by inserting the tenon of the base into the mortise of different building block components. The position and angle of the base are determined by the connected building block components. For example, the base can be connected to a single building block component, or simultaneously connected to multiple building block components by using different mortises, or can also be connected to it after the building block components are stacked. And after the mortise and tenon are inserted, the base is fixed to the connected building block component. Supported by the connected building block components, the base stably maintains the adjusted position and angle. Therefore, it can also be effectively adapted in toy building block sets such as toy track boards that require stable structures for splicing objects. When children play, they can give full play to their creativity more freely for splicing, making the types of splicing objects that can be spliced more abundant. Description of the Drawings

[0030] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship when the product of the present utility model is normally placed, and is only for the convenience of simplifying the description, rather than indicating or implying that the orientation must have a specific orientation and specific orientation structure and operation, and therefore should not be construed as a limitation to the present utility model.

[0032] Embodiment 1:

[0033] Such as Figures 1 to 3 , Figure 4 , Figure 6 and Figure 10As shown in the figure, the utility model first relates to a building block connection component, which includes a connecting piece 1 and a base 2. The connecting piece 1 is rotatably connected to the base 2. At least one mortise a2 for mating with the tenon a1 of other building block components of the configured toy building block set is provided on the base 2. The building block connection component of the utility model utilizes the rotation of the connecting piece 1 around the docking position with the base 2 to drive the connected building block components to adjust the angle. And when a building block component is connected to the connection head 101 of the connecting piece 1, its base 2 can also participate in the splicing by inserting the tenon a1 of different building block components through its mortise a2. The position and angle of the base 2 are determined by the connected building block components. For example, the base 2 can be connected to a single building block component, or connected to multiple building block components simultaneously using different mortises a2, or can also be connected to it after the building block components are stacked. And after the mortise a2 is inserted with the tenon a1, the base 2 is fixed to the connected building block component. Supported by the connected building block components, the base 2 stably maintains the adjusted position and angle. Therefore, it can also be effectively adapted to toy building block sets such as toy track boards 3 that require a stable structure for splicing objects. When children play, they can use their creativity more freely to splice, making the types of splicing objects that can be spliced more diverse. In addition, the connecting piece has two opposite and spaced wings 102. Overall, the shape of the connecting piece with the wings 102 is L-shaped. The space between the two wings 102 forms a slot for insertion. When the utility model is configured in a toy building block set with a track board 3, the track board 3 can be embedded into the slot and limited by the wings 102 on both sides, effectively restricting the lateral movement of the track board 3 and improving its installation stability.

[0034] As Figure 3 , Figure 4 and Figure 6 shown in the figure, a rotating hole 201 is provided on the base 2. The rotating hole 201 is connected to any one of its mortises a2. The connecting piece 1 has a rotating rod 103. The connecting piece 1 is inserted into the rotating hole 201 through the rotating rod 103. The connecting piece 1 can rotate around the base 2 through the rotating rod 103, realizing the rotational connection with the base 2. And the rotation of the connecting piece 1 can be achieved by a simple twisting action, so the orientation adjustment is more convenient.

[0035] As Figure 3 , Figure 4 and Figure 6 shown in the figure, a limiting flange 103a is formed on the outer peripheral wall of the rotating rod 103. The limiting flange 103a cooperates with the step at the transition position between the rotating hole 201 and the mortise a2. Overall, the shape of the connecting piece with the limiting flange 103a is in the shape of a capital I. When the rotating rod 103 is inserted into the rotating hole 201 of the base 2 and the limiting flange 103a cooperates with the step at the transition position of the mortise a2, both sides of the connecting piece 1 are in contact with the base 2, forming a clamping of the base 2, thereby effectively restricting the movement of the connecting piece 1 relative to the base 2 and achieving a more stable connection.

[0036] As Figure 3 、 Figure 4 and Figure 6 shown, an insertion tube 202 is formed at the transition position between the drilling hole 201 and the mortise a2. The insertion tube 202 extends in the central direction of the mortise a2. The inner diameter of the insertion tube 202 decreases from the direction of the drilling hole 201 to the mortise a2, thereby forming a conical tube structure. And a partition groove 202a is formed along the length direction on the circumferential side wall of the insertion tube 202. The number of the partition grooves 202a is not particularly limited. Through the partition groove 202a, when the two parts of the insertion tube 202 on both sides thereof are subjected to radial forces, they can be bent to a certain extent. The shape of the rotating rod 103 matches the inner tube section of the insertion tube 202. When the rotating rod 103 is inserted into the inner tube section of the insertion tube 202, the limiting flange 103a protruding from the outer wall of the rotating rod 103 presses against the inner wall of the insertion tube 202, so that the two parts of the insertion tube 202 on both sides of each partition groove 202a are bent and deformed outward until the limiting flange 103a passes through the inner tube section of the insertion tube 202 and cooperates with the bottom step of the insertion tube 202. When the connecting member 1 is subjected to an external force in the direction away from the drilling hole 201, due to the existence of the limiting flange 103a, it is more difficult for the rotating rod 103 to pass through the inner tube section of the insertion tube 202 under this external force, further improving the connection stability between the connecting member 1 and the base 2.

[0037] Embodiment 2:

[0038] As Figure 2 、 Figure 5 and Figure 10 shown, in this embodiment, another design is made on the basis of the above Embodiment 1. Specifically, the connecting member 1 has a connecting head 101. The connecting head 101 is adapted to the slots 303 on other building block members of the configured toy building block set, and is connected to other building block members of the configured toy building block set in a mortise and tenon manner. With the clamping of the cooperating fins 102, a more stable connection and fixation are achieved, and there are at least two connecting heads 101 so as to be able to connect two or more building block members simultaneously.

[0039] As Figure 2 、 Figure 5 and Figure 10As shown in the figure, the connector 101 includes a connecting arm 101a and a pawl 101b. The pawls 101b are formed on two opposite sides of the connecting arm 101a. The free ends of the pawls 101b are bent towards the same-side side wall of the connecting arm 101a, and a buffer groove is formed between the pawls 101b and the connecting arm 101a. The buffer groove allows the pawls 101b to have a certain deformable space when subjected to an external pressure towards the side of the connecting arm 101a, and at the same time, the connecting arm 101a restricts the deformation amplitude of the pawls 101b in this direction. When the connector 1 of the connecting component of the present utility model is inserted into the slot 303 of the building block member of the configured toy building block set through its connector 101, it is ensured that the entire connector 101 is configured to be larger than the slot 303 when the connector 101 can be inserted into the building block toy slot 303 after the pawls 101b are deformed under pressure. During splicing, the two pawls 101b are subjected to the pressure towards the connecting arm 101a exerted by the inner wall of the slot 303. After the pawls 101b are pressed, they deform towards the first buffer groove and generate an elastic force for restoring deformation. After being inserted, the pawls 101b can closely abut against the inner wall of the slot 303 under the action of the elastic force, so that the connector 1 and the connected building block member are firmly connected, effectively restricting the relative movement between them.

[0040] As Figures 7 to 10 shown in the figure, the present utility model also relates to a toy building block set having the above-mentioned building block connecting component. In addition to the building block connecting component, it further includes a plurality of track plates 3 and building blocks 4. The slot 303 is located at the end of each track plate 3. The building block 4 has at least one tenon a1 and a mortise a2. Each track plate 3 can be spliced into a toy track system by connecting the ends. The track plate 3 is inserted and matched with the connector 101 of the connecting head of the building block connecting component through the slot 303. After the matching, the pawl 101b of the connecting head 101 is closely attached to the inner wall of the slot 303, making the track plates 3 connected by the connector 1 not prone to relative movement, realizing the stable connection between the track plates 3, and enabling the structure of the spliced toy track system to also remain stable. The building blocks 4 are divided into various types according to the different numbers of tenons a1 and mortises a2 they have, such as a column-shaped building block 4 with only a single tenon a1 and a mortise a2, a rectangular building block 4 with three tenons a1 and mortises a2, etc. The building blocks 4 can be freely spliced with each other by using the tenons a1 and mortises a2. The base 2 of the building block connecting component can be fixed in cooperation with the tenon a1 of any building block 4 by using its mortise a2 to maintain any required position and angle, and thus can also be effectively adapted in a toy building block set where objects to be spliced such as toy track plates 3 need to maintain a stable structure. When children play, they can give full play to their creativity more freely for splicing, making the types of spliced objects more diverse. It should be mentioned that the track plates 3 include straight tracks, curved tracks, and climbing tracks. Based on the above settings, the types of tracks included in the building block toy set of the present utility model are greatly enriched. Children can splice straight tracks, curved tracks, and climbing tracks into a rich track system, giving children's creativity and imagination a broader development space.

[0041] As Figure 7 shown, each track slab 3 is formed with two spaced cross beams, and the space between the two cross beams forms a track groove. The cross beam sequentially includes an outer beam 301 and an inner beam 302 from outside to inside. The height of the outer beam 301 is greater than that of the inner beam 302, so that a step position is formed between it and the inner beam 302. The track slab 3 with the above structure can be used for toy trains to run and as a track for ball bearings to roll at the same time, thus greatly enriching the playing methods of the whole toy building block set. When the toy train is placed on the track slab 3, the wheels of the toy train are supported by the inner beams 302 symmetrically close to the respective approaching sides of the opposed outer beams 301, or supported by the bottom wall of the track groove, ensuring that the placed toy train remains balanced. Due to the different spacings between the outer beams 301 of the two cross beams and between the inner beams 302, stable support can be provided for toy trains with different wheel gauges, thus meeting the running requirements of toy trains with diversified wheel gauges. After the toy train is placed on the inner beam 302 of the track slab 3, the lateral movement is restricted by the step positions formed between the inner beam 302 providing support and the adjacent inner beam 302 or outer beam 301, or restricted by the inner beams 302 on both sides of the inner beam 302 in the track groove, avoiding the deviation of the running direction and derailment of the toy train when passing through the inner beam 302 of the track slab 3. In addition, when used as a track for ball bearings to roll, after the ball bearings are placed, they can be supported and limited by the step positions, so that the toy ball bearings are stably placed in the inner beam 302 of the track slab 3 and avoid derailment when rolling.

[0042] The above embodiments and the descriptions in the specification only illustrate the principles and the best embodiments of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
