Description
Technical Field
[0001] This utility model relates to the field of beach toy technology, and more specifically, to a beach puzzle toy. Background Technology
[0002] Sandcastling is a recreational activity on the beach. This activity usually involves filling sand into sand molds, compacting it, and then demolding it to create sandcastle shapes or other designs. Sandcastling not only improves children's hands-on skills but also stimulates their imagination, making it popular with both children and adults.
[0003] However, the relevant technology has at least one of the following problems: the sand sculpture mold in the prior art is a fixed integrated structure, and the internal molding design of the sand sculpture mold is a pre-defined specific shape. Therefore, users can only make a single and repetitive sand model through the sand sculpture mold. Utility Model Content
[0004] The technical problem solved by this utility model is that the existing sand sculpture molds are fixed integrated structures, and the internal molding design of the sand sculpture molds is a pre-defined specific shape. Therefore, users can only make a single and repetitive sand model through the sand sculpture mold.
[0005] To address the aforementioned issues, this utility model provides a beach assembly toy comprising: multiple modular components and detachable connecting components, wherein each modular component includes a splicing end and a mating end arranged opposite to each other; the detachable connecting components are respectively disposed at the splicing end and the mating end; wherein, the multiple modular components are interlocked with each other through the detachable connecting components and together form at least one cavity structure for accommodating sand.
[0006] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: through the free combination of multiple modular components, sand models that far exceed traditional molding molds can be constructed. This breaks the traditional single-operation mode of filling and demolding, and forms a closed-loop training system for creativity, which includes splicing design, sand molding, and structural reconstruction. The free splicing mode greatly increases children's imagination space and fundamentally solves the problem of the constraints on children's creativity and imagination development imposed by the integrated fixed structure of beach molds.
[0007] In one embodiment of this utility model, the detachable connection component includes: a tenon guide portion, which is provided along the left and right edges of the modular component; and a T-shaped slide structure, which is provided along the upper and lower edges of the modular component.
[0008] Compared with existing technologies, the technical effects achieved by this solution are as follows: the left and right edge tenon guides enable rapid horizontal splicing and positioning, and the T-shaped sliding groove structure set on the upper and lower edges ensures vertical shear resistance and prevents the problem of easy tipping when multiple modules are stacked.
[0009] In one embodiment of this utility model, the tenon guide includes: a dovetail protrusion groove, a reverse dovetail guide groove, and a first pin; the dovetail protrusion groove is located on one of the left and right sides of the modular component; the reverse dovetail guide groove is located on the side of the modular component away from the dovetail protrusion groove; wherein, when any two modular components are spliced left and right, the adjacent dovetail protrusion groove and the reverse dovetail guide groove are engaged with each other; the first pin is slidably located in the engaged dovetail protrusion groove and the reverse dovetail guide groove to lock the two adjacent modular components.
[0010] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: forming a two-way interlocking topology structure: the dovetail protrusion groove and the reverse dovetail guide groove form a geometric constraint, eliminating the lateral gap problem of traditional assembly toys; the first pin through design provides double locking protection: mechanical self-locking plus active pin fixing.
[0011] In one embodiment of this utility model, the dovetail protrusion includes a head groove and a tail groove; a recessed portion is provided on the side of the head groove away from the tail groove; the first pin includes a locking portion and a hand-held portion; wherein, when the hand-held portion and the recessed portion form a tactile positioning engagement, the locking portion reaches the first locking position.
[0012] Compared with existing technologies, the technical effects achieved by this solution are as follows: users can sense the locking critical point through hand pressure, avoiding the problem of insufficient structural strength due to incomplete locking. Furthermore, the first pin can be easily inserted and removed by hand, and the easy operation avoids damage to the formed sand body when dismantling the modular components during sand body forming.
[0013] In one embodiment of this utility model, the locking part has a buckle protrusion at one end near the hand-held part; the first end groove has a buckle part; wherein, when the locking reaches the first locking position, the buckle protrusion engages with the buckle part.
[0014] Compared with existing technologies, the technical effect achieved by this technical solution is as follows: by cooperating with the buckle protrusion and the buckle part, it is possible to determine whether the first pin has reached the locked position by distinguishing whether a locking sound is produced and by tactile sensation, thus further ensuring the reliability of locking.
[0015] In one embodiment of this utility model, the T-shaped slide structure includes: a first slide member, a second slide member, and a second pin; the first slide member is disposed at one of the upper and lower ends of the modular component; the second slide member is disposed at the end of the modular component away from the first slide member; wherein, when any two modular components are spliced together, the adjacent first slide member and the second slide member are engaged with each other; the second pin is slidably disposed within the engaged first slide member and the second slide member to lock the two adjacent modular components.
[0016] Compared with the existing technology, the technical effect achieved by adopting this technical solution is that the second pin forms a sliding fit with the first and second sliding parts to further lock the two spliced modular components and ensure the reliability of the connection.
[0017] In one embodiment of this utility model, when any two modular components are spliced together, the adjacent first and second sliding groove components together form a closed groove; a straight track is provided on the outer surface of the groove through the first and second sliding groove components; the second pin includes: a pin portion, the longitudinal section of which matches the inner cavity of the groove and slides linearly inside the groove; and a handle portion, which is fixedly connected to one side of the pin portion through a connecting portion, and the handle portion is movable on the outside of the groove.
[0018] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the design of the continuous closed tank forms a physically closed guide channel, which prevents sand particles from entering the tank during use. Furthermore, the limiting mechanism of the straight track and the correspondence between the tank space and the shape of the second pin limit the displacement trajectory of the second pin, preventing the second pin from being difficult to lock or unlock due to the tilt of the sand surface.
[0019] In one embodiment of this utility model, the first sliding groove is provided with a tactile rib on the side near the handle, wherein the tactile rib and the handle form a tactile positioning fit.
[0020] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: by cooperating with the tactile ribs and the handle, a multi-point tactile perception path is created. The height difference of the protrusions of the tactile ribs forms a point of sudden change in resistance. During the sliding process, the user can clearly perceive the two positioning stages of pre-locking and full locking, which ensures the reliability of the locking between the upper and lower parts of the modular components.
[0021] In one embodiment of this utility model, the modular component includes: a first type of splicing component, a second type of splicing component, and a third type of splicing component; the first type of splicing component is a sheet-like structure; the second type of splicing component is a sheet-like structure with a volume smaller than that of the first type of splicing component; and the third type of splicing component is an arc-shaped structure.
[0022] Compared with existing technologies, the technical effects achieved by adopting this technical solution are: three different types of splicing parts can achieve a wider variety of splicing combinations, improving the playability of beach splicing toys.
[0023] In one embodiment of this utility model, any modular component is provided with a reinforcing rib structure.
[0024] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the addition of reinforcing ribs to the modular components improves their resistance to deformation, allowing them to withstand greater pressure during use and enhancing their reliability.
[0025] By adopting the technical solution of this utility model, the following technical effects can be achieved:
[0026] (1) By freely combining at least three modular components, the limitations of the single fixed form of traditional beach toys are broken, releasing the potential of children's spatial design and improving the space for children to exercise their imagination and creativity;
[0027] (2) The modular components are connected by mortise and tenon guides on the left and right edges and T-shaped sliding grooves on the upper and lower edges, which ensures the stability and reliability of the connection between the modular components. When in use, they can effectively withstand the pressure of the sand and maintain a stable shape.
[0028] (3) The combination of the first type of splicing parts, the second type of splicing parts and the third type of splicing parts can create a richer sand body shape, increase the overall fun and improve the user experience. Attached Figure Description

[0042] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0043] See Figure 1 , Figure 1 This is a schematic diagram of the assembly structure of a beach puzzle toy provided in an embodiment of the present utility model, and in conjunction with... Figures 2 to 10Specifically, a beach building toy includes at least three types of interlocking modular components 1; the connecting surfaces of any type of modular component 1 are provided with detachable connecting components with complementary structures; wherein, multiple modular components 1 are spliced end to end by detachable connecting components to form a cavity structure, and when sand is filled into the cavity structure, the inner surface of the cavity structure constitutes a sand forming surface.
[0044] See Figure 2 and Figure 3 Specifically, the modular component 1 includes a first type of splicing component 10, a second type of splicing component 20 and a third type of splicing component 30. The first type of splicing component 10 is a sheet-like convex structure, and a groove structure that complements the shape of the convex structure is provided on the other side away from the convex part. The first type of splicing component 10 is axially symmetrical along its convex direction.
[0045] See Figure 4 and Figure 5 Furthermore, the structural shape of the second type of splicing component 20 is similar to that of the first type of splicing component 10, and the area of the shaped surface of the second type of splicing component 20 is half the area of the shaped surface of the first type of splicing component 10. When two second type of splicing components 20 are spliced together from left to right, the area and outline of the overall shaped surface are consistent with the shaped surface of the first type of splicing component 10.
[0046] See Figures 6 to 8 Furthermore, the third type of splicing component 30 has an arc-shaped structure, and the overall structure of the third type of splicing component 30 is similar to that of the first type of splicing component 10 and the second type of splicing component 20. In other words, the third type of splicing component 30 can be regarded as the lateral axis of the first type of splicing component 10 or the second type of splicing component 20 being bent.
[0047] More specifically, the protruding part of any modular component 1 corresponds to and complements the grooved part of any other modular component 1, and the two interlock during splicing to achieve splicing.
[0048] Preferably, the arc of the third type of splicing component 30 is 45°.
[0049] Preferably, the heights of the first type of splicing component 10, the second type of splicing component 20, and the third type of splicing component 30 are equal in the vertical direction. When any two of them are spliced horizontally, the upper or lower surface of the resulting whole constitutes a complete smooth plane.
[0050] See Figure 9 and Figure 10 The detachable connection components include: a tenon guide 40, which is provided along the left and right edges of the modular component 1; and a T-shaped slide structure 50, which is provided along the upper and lower edges of the modular component 1.
[0051] Optionally, the tenon guide part 40 consists of complementary male and female tenon units on the left and right sides of the modular component 1. The male tenon has a wedge-shaped protrusion design, and the female tenon has a tapered groove shape. During assembly, the beveled surfaces of the tenon and mortise guide and correct each other to achieve precise horizontal positioning.
[0052] Optionally, the T-shaped slide structure 50 is a through-type T-shaped slide along the upper and lower edges of the module. The top or bottom slide is equipped with a standard-specification guide rail and an adjustable locking slider. When the two T-shaped slides are vertically superimposed, the slider moves along the slide to the predetermined position and triggers the self-locking mechanism, thus simultaneously completing the vertical limiting and axial load transmission.
[0053] The tenon guide portion 40 includes a dovetail protrusion groove and a reverse dovetail guide groove 402; the dovetail protrusion groove and the reverse dovetail guide groove 402 are respectively provided on the left and right sides of the modular component 1; the detachable connection assembly also includes a first pin 80; wherein, the reverse dovetail guide groove 402 of any modular component 1 is axially complementary to the dovetail protrusion groove of another modular component 1, so that the first pin 80 passes through the reverse dovetail guide groove 402 and the dovetail protrusion groove.
[0054] Specifically, the dovetail-shaped protrusion groove includes two protruding head end grooves 401 and tail end grooves 403. The head end grooves 401 and tail end grooves 403 are respectively set at both ends of the groove of the modular component 1 and are located on one side of the connecting surface. The reverse dovetail guide groove 402 is a protruding middle groove. The middle groove is set at the protruding structure position of the modular component 1 and is also located on one side of the connecting surface.
[0055] Furthermore, the dovetail protrusion groove and the reverse dovetail guide groove 402 are matched in opposite directions to form a complementary structure. When the two modular components 1 are spliced together, the first end groove 401, the last end groove 403 and the inner cavity of the middle groove are interconnected and aligned along the vertical axis.
[0056] Furthermore, the first pin 80 is vertically inserted into the tenon guide 40, and the first pin 80 passes through the first end groove 401, the middle groove and the tail end groove 403 to lock the two adjacent modular components 1.
[0057] Optionally, the shape of the first pin 80 and the transverse cross-sectional shape of the groove in the tenon guide 40 are both rectangular, which further increases the stability between the two adjacent left and right components.
[0058] Optionally, the shape of the first pin 80 and the transverse cross-section shape of the groove in the tenon guide part 40 are both cylindrical, which increases the rotational freedom between the two adjacent components and increases the overall interest.
[0059] The dovetail-shaped protrusion includes a head groove 401 and a tail groove 403; a retraction portion 101 is provided on the side of the head groove 401 away from the tail groove 403; the first pin 80 includes a locking portion 802 and a hand-held portion 801; wherein, when the hand-held portion 801 and the retraction portion 101 form a tactile positioning engagement, the locking portion 802 passes completely through the dovetail-shaped protrusion.
[0060] Specifically, the dovetail-shaped protrusion is divided into a head groove 401 and a tail groove 403 along the axial direction. The head groove 401 is provided with a recess 101 at its end. The recess 101 is shallow and extends to form a tactile positioning platform. The tail groove 403 maintains the standard dovetail profile. The tactile positioning is specifically that when the first pin 80 moves to the point where the handheld part 801 contacts the tactile positioning platform, the user receives resistance feedback. The user learns from the feedback that the locking part 802 has reached the first locking position, thus completing the locking of the two adjacent modular components 1 on the left and right.
[0061] The locking part 802 has a buckle protrusion 803 at one end near the hand-held part 801; the head end groove 401 has a buckle part 4011 at the position corresponding to the buckle protrusion 803.
[0062] Specifically, the latching part 4011 includes a latching groove and an elastic stop. When the locking part 802 is inserted into the tenon guide part 40, the latching protrusion 803 engages with the latching groove. The elastic stop is used to stop the locking part 802 from going further in and provides an elastic force in one direction when it goes too far in, so that the latching protrusion 803 returns to the latching groove.
[0063] The T-shaped slide structure 50 includes a first slide member 501 and a second slide member 502; the first slide member 501 and the second slide member 502 are respectively arranged along the upper and lower ends of the modular component 1; when the two modular components 1 are spliced together, the first slide member 501 and the second slide member 502 together form a continuous closed groove, and the outer surface of the groove is provided with a through straight track 5012 in the vertical direction; the detachable connection component also includes a second pin 90, the second pin 90 is engaged with the T-shaped slide structure 50, and the sliding trajectory of the second pin 90 is constrained by the straight track 5012; wherein, when the second pin 90 slides from the first position to the second position along the straight track 5012, the second pin 90 and the T-shaped slide structure 50 interfere and lock.
[0064] Specifically, the top of the modular component 1 is fitted with a first sliding groove 501, which is the upper T-shaped rail, and the bottom is integrated with a second sliding groove 502, which is the lower T-shaped rail. The upper rail is opened on the outer side of the first sliding groove 501, and the lower rail is opened on the second sliding groove 502. The opening directions of the upper and lower sliding grooves are mirror symmetrical to each other. When two adjacent modular components 1 are spliced together, they form a continuous closed groove. The outer side of the groove is formed by splicing the upper and lower rails to form a complete straight rail 5012.
[0065] Furthermore, the first type of splicing component 10 is provided with two sets of T-shaped sliding groove structures 50, and the second type of splicing component 20 and the third type of splicing component 30 are provided with one set of T-shaped sliding groove structures 50.
[0066] Optionally, there is a tenon joint between the first slide rail 501 and the second slide rail 502, which allows for better positioning and engagement.
[0067] The second pin 90 includes: a pin portion 902, the longitudinal section of which matches the inner cavity of the groove and slides linearly inside the groove; a handle portion 901, which is fixedly connected to one side of the pin portion 902 via a connecting portion 903 and is movable outside the groove; and a tactile rib 5011 is provided on the side of the first sliding groove member 501 near the handle portion 901, the tactile rib 5011 and the handle portion 901 forming a tactile positioning engagement.
[0068] Specifically, the tactile rib 5011 is oriented away from the groove and is located on the movement path of the handle 901.
[0069] Furthermore, the structure of the connecting part 903 and the linear track 5012 are matched, and the movement of the second pin 90 is affected by the cooperation between the connecting part 903 and the linear track 5012.
[0070] Furthermore, the end of the second pin 90 90 that is away from the handle 901 is set as an inverted trapezoidal structure, so that the second pin 90 can enter the second slide groove 502 more easily.
[0071] Among them, the first sliding groove 501, the second sliding groove 502, the dovetail protrusion groove and the reverse dovetail guide groove 402 on any of the modular components 1 are positioned in the same way from the same perspective.
[0072] The connecting surface of modular component 1 is provided with an arc-shaped reinforcing rib structure group.
[0073] Specifically, there are two types of reinforcing ribs: one is a corrugated reinforcing rib 701, and the other is a superimposed reinforcing rib 702. The corrugated reinforcing rib consists of multiple wave-shaped or arc-shaped reinforcing ribs that are staggered and superimposed, so that the crest of one rib and the trough of another rib are located on the same vertical axis, forming a fish-shaped reinforcing rib, which can better withstand the force in the vertical direction. The other type of reinforcing rib 702 is a terraced rib that is stacked outwards in layers, making the thickness of the modular component 1 thicker layer by layer, which can better withstand the pressure from the horizontal direction.
[0074] The side of modular component 1 away from the connection surface is the shaped surface; the shaped surface is provided with a shaped pattern 60.
[0075] Specifically, when modular components 1 are assembled to form a complete closed model, the shaped surface is located on the inner wall of the closed model. Sand is filled into the closed inner wall, and the surface of the resulting sand mold presents the designed shaped pattern 60, making the produced sand mold more aesthetically pleasing.
[0076] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
