Description

Technical Field

[0001] This utility model relates to the field of toy accessories technology, specifically a plastic building block fixing base. Background Technology

[0002] Building blocks are usually designed as a set of individual blocks of different shapes. After the user scrambles the blocks, they assemble them according to their shape characteristics and put them back in their original positions. This allows the player to recognize the shape of objects, thereby cultivating children's cognition and thinking.

[0003] According to a plastic building block and base structure disclosed in the public notice (Announcement No.: CN216456903U), the above application has low manufacturing and usage costs, and enables the building blocks to be connected and fixed quickly, stably and safely, which greatly improves operational efficiency and accuracy, reduces the workload of personnel, and has better applicability.

[0004] However, in actual use, the building blocks need to be inserted into the sockets of the base. Generally, plastic building blocks are inserted by making the insertion part of the block slightly larger than the socket to achieve a tight fit. However, repeated insertion and removal over a long period of time can easily lead to a situation where they cannot be inserted tightly in the future, thereby reducing the effectiveness of the plastic building blocks. In view of this, we propose a plastic building block fixing base. Utility Model Content

[0005] The purpose of this invention is to provide a plastic building block fixing base to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic building block fixing base, including a plug-in base, wherein a plug-in interface is provided at the center of the plug-in base, a snap-fit ​​assembly is detachably installed on the arc-shaped outer surface of the plug-in base, and a clamping structure is provided inside the plug-in interface, the clamping structure including:

[0007] The fixed rod has a movable groove inside the insertion interface, and the fixed rod is fixedly installed inside the movable groove. An L-shaped plate is installed through and rotatably on the fixed rod, and a spiral spring is sleeved on the arc-shaped outer wall of the fixed rod.

[0008] A rubber ball is fixedly installed on the bottom inner wall of an L-shaped plate, and rubber ribs are fixedly connected to the side wall of the L-shaped plate.

[0009] Preferably, the plug-in base is cylindrical and the plug interface is square hole-shaped. The buckle assembly includes a connecting plate and springs and buckle blocks that are movably connected to the left and right ends of the connecting plate. The inner wall of the plug-in base is provided with a buckle interface that is compatible with the buckle assembly. Thus, the buckle assembly enables multiple plug-in bases to be snapped together.

[0010] Preferably, the number of clamping structures is set to two sets, and the two sets of clamping structures are mirror images of each other at the right angle inside the insertion interface, thereby maximizing the contact area of ​​the L-shaped plate when fixing the plastic building blocks.

[0011] Preferably, the bottom of the sidewall of the rubber ridge is provided as an arc-shaped surface, so that the upward movement tendency of the rubber ridge is suppressed after it comes into contact with the insertion part of the plastic building block, thus preventing the plastic building block from easily falling out of the insertion interface.

[0012] Preferably, a blocking component is provided on the side wall of the L-shaped plate. The blocking component includes an arc-shaped groove, which is formed on the side wall of the L-shaped plate. A rubber strip is fixedly connected to the end of the rubber rib, and a guide post is fixedly installed on the side wall of the rubber strip.

[0013] Preferably, the rubber strip is located at the end of the rubber ridge away from the center of the L-shaped plate, and the guide post is located inside the arc groove. Through the guidance of the arc groove, the end of the rubber strip away from the rubber ridge can move along the arc groove as its movement path.

[0014] Compared with the prior art, this utility model provides a plastic building block fixing base, which has the following features:

[0015] Beneficial effects:

[0016] 1. This plastic building block fixing base, equipped with a snap-fit ​​assembly, allows the plastic building block to contact the rubber ball when inserted into the insertion interface from top to bottom. This causes the L-shaped plate to deflect around the fixing rod as the rotation center, thus suppressing the upward movement of the plastic building block after the rubber edge contacts the insertion part, preventing the plastic building block from easily falling out of the insertion interface. The method of using the L-shaped plate to deflect around the fixing rod as the rotation center replaces the original plastic locking with different diameters. This is achieved by the rubber ball contacting the bottom end of the plastic building block. At the same time, the multiple arrays of rubber edges with curved surfaces ensure stable insertion of the plastic building block on the insertion base, making it convenient for children to assemble and use.

[0017] 2. The plastic building block fixing base is equipped with a blocking component. When the plug part of the plastic building block is inserted into the plug interface, the L-shaped plate deflects, causing the rubber strip to contact the surface of the plug part of the plastic building block. Since the surface of the object is not smooth, the friction force on the surface of the rubber strip is different at different points, which causes the rubber strip itself to produce irregular slight deformation. This increases the blocking force on the plug part of the plastic building block in the plug interface, ensuring the positioning effect of the plastic building block on the plug base and preventing it from easily falling off when children use it, thus affecting the user experience.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a plastic building block fixing base, including a plug-in base 1, a plug-in interface 2 is provided at the center of the plug-in base 1, a buckle assembly 3 is detachably installed on the arc-shaped outer surface of the plug-in base 1, and a pressing structure 4 is provided inside the plug-in interface 2. The pressing structure 4 includes a fixing rod 41, an L-shaped plate 42, a spiral spring 43, a rubber ball 44, and a rubber ridge 45.

[0025] In one embodiment of this utility model, the insertion interface 2 has an internal movable groove, and a fixing rod 41 is fixedly installed inside the movable groove. An L-shaped plate 42 is installed through and rotatably on the fixing rod 41. A spiral spring 43 is sleeved on the arc-shaped outer wall of the fixing rod 41. A rubber ball 44 is fixedly installed on the bottom inner wall of the L-shaped plate 42, and a rubber rib 45 is fixedly connected to the side wall of the L-shaped plate 42.

[0026] Furthermore, the plug-in base 1 is cylindrical, and the plug-in interface 2 is square. In addition, there are four sets of snap-fit ​​components 3, which are evenly distributed in a circumferential array on the arc-shaped outer wall of the plug-in base 1. Specifically, the snap-fit ​​component 3 includes a connecting plate and springs and locking blocks that are movably connected to the left and right ends of the connecting plate. The inner wall of the plug-in base 1 is provided with a snap-fit ​​interface that is compatible with the snap-fit ​​component 3. Thus, through the setting of the snap-fit ​​component 3, multiple sets of plug-in bases 1 can be snapped together to form a plastic building block fixing base with an adjustable area, so as to adapt to the splicing of plastic building block compositions of different sizes.

[0027] In addition, two sets of clamping structures 4 are provided, and the two sets of clamping structures 4 are mirror images of each other with the center of the insertion interface 2 as the center of symmetry. That is, the two sets of clamping structures 4 are mirror images of each other at right angles inside the insertion interface 2, thereby maximizing the contact area of ​​the L-shaped plate 42 when fixing the plastic building blocks. At the same time, the movable groove is L-shaped, and the connection between the movable groove and the insertion interface 2 is set to be outwardly inclined to avoid the movable groove interfering with the rotation of the L-shaped plate 42. Furthermore, two sets of spiral springs 43 are provided, and the two sets of spiral springs 43 are perpendicular to the L-shaped plate 42. The straight central axis is symmetrically arranged, and the two ends of the spiral spring 43 are fixedly connected to the arc-shaped outer wall of the fixed rod 41 and the side surface of the L-shaped plate 42, respectively. This makes the L-shaped plate 42 always have the tendency to rotate in the opposite direction to achieve reset after rotating around the fixed rod 41. Specifically, in the initial state, the L-shaped plate 42 is inclined with its bottom protruding into one side of the insertion interface 2, so that when the plastic building block is inserted into the insertion interface 2 from top to bottom, it will contact the rubber ball 44, thereby causing the L-shaped plate 42 to deflect around the fixed rod 41.

[0028] Meanwhile, two sets of rubber ribs 45 are provided, and the two sets of rubber ribs 45 are mirror images of each other on the inner surface of the L-shaped plate 42. Each set of rubber ribs 45 consists of multiple rubber ribs 45 arranged in a vertical linear array on the side wall of the L-shaped plate 42. Specifically, the bottom of the side wall of the rubber ribs 45 is set with an arc-shaped surface, which suppresses the upward movement of the rubber ribs 45 after contacting the insertion part of the plastic building block, preventing the plastic building block from easily falling out of the insertion interface 2. The original plastic locking with different diameters is replaced by the L-shaped plate 42 deflecting with the fixed rod 41 as the rotation center. The contact between the rubber ball 44 and the bottom end of the plastic building block is used to trigger the locking mechanism. At the same time, the multiple sets of rubber ribs 45 with arc-shaped surfaces arranged in an array ensure the stable insertion of the plastic building block on the insertion base 1, making it convenient for children to assemble and use.

[0029] In an embodiment of this utility model, a blocking component 5 is provided on the side wall of the L-shaped plate 42. The blocking component 5 includes an arc groove 51, which is formed on the side wall of the L-shaped plate 42. A rubber strip 52 is fixedly connected to the end of the rubber rib 45, and a guide post 53 is fixedly installed on the side wall of the rubber strip 52.

[0030] Specifically, the number of blocking components 5 is the same as the number of rubber ribs 45. Meanwhile, the rubber band 52 is located at the end of the rubber rib 45 furthest from the center of the L-shaped plate 42, and the guide post 53 is located inside the arc-shaped groove 51. Guided by the arc-shaped groove 51, the end of the rubber band 52 furthest from the rubber rib 45 can move along the arc-shaped groove 51 as its path, allowing the rubber band 52 to deform under external force. Specifically, when the plug part of the plastic building block is inserted into the insertion interface 2, as the L-shaped plate 42 deflects, the rubber band 52 comes into contact with the surface of the plug part of the plastic building block. Because the surface of the object is not smooth, the frictional force on the surface of the rubber band 52 is different at different points, causing the rubber band 52 to undergo irregular slight deformation. This increases the blocking force on the plug part of the plastic building block within the insertion interface 2, ensuring the positioning effect of the plastic building block on the insertion seat 1 and preventing it from easily falling off when used by children, thus affecting the user experience.

[0031] In this invention, several plug-in bases 1 are connected in a planar manner through the snap-fit ​​assembly 3 to form a fixed base for plastic building blocks of the required size. Then, the plug-in part of the plastic building block is aligned with the plug-in interface 2 and inserted. When the plastic building block is inserted into the plug-in interface 2 from top to bottom, it will contact the rubber ball 44, thereby causing the L-shaped plate 42 to deflect around the fixed rod 41 as the rotation center. This causes the rubber rib 45 to suppress the upward movement of the plastic building block after contacting the plug-in part, preventing the plastic building block from easily falling out of the plug-in interface 2. By using the L-shaped plate 42 to deflect around the fixed rod 41 as the rotation center, the original plastic locking with different diameters is replaced. This is achieved by the contact between the rubber ball 44 and the bottom end of the plastic building block. At the same time, the multiple sets of arrayed rubber ribs 45 with arc-shaped surfaces ensure the stable insertion of the plastic building block on the plug-in base 1, making it convenient for children to assemble and use.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
