Description

Technical Field

[0001] This invention relates to the field of parking stone technology, specifically to a spherical hollow parking stone and its production mold. Background Technology

[0002] Parking stones are stones used to block cars. They are common components in municipal engineering and other fields, used to restrict vehicle movement. They are frequently used in shopping malls, plazas, and pedestrian-vehicle separation points to obstruct traffic. In emergencies, they can be removed to allow vehicles to pass. To prevent parking stones from being moved arbitrarily, current technology often uses solid natural stone carved from a single piece or made from specially formulated powder materials through a molding process. However, regardless of the form, parking stones are solid structures with considerable weight. Due to their weight, especially large ones, moving and transporting them is difficult and inconvenient.

[0003] Therefore, there is an urgent need for a type of bollard that is easy to move and transport, meets weight requirements during use, and prevents it from being moved arbitrarily, so as to ensure its effectiveness in stopping vehicles. Summary of the Invention

[0004] This invention proposes a spherical hollow parking stone and its production mold, which solves the problem that solid parking stones are too heavy and inconvenient to transport in related technologies.

[0005] The technical solution of the present invention is as follows: A spherical hollow parking stone includes a base and a sphere connected in sequence. Both the base and the sphere are hollow structures. The inner wall of the base has at least two slots. The base also includes a bottom plate with a locking block for engaging with the slots. After the locking block engages with the slots, the bottom plate closes the base.

[0006] As a further technical solution

[0007] There are three card blocks and three card slots. The card blocks are rectangular and the card slots are L-shaped.

[0008] As a further technical solution

[0009] The slot includes an insertion section and a snap-fit ​​section.

[0010] As a further technical solution

[0011] The base plate has a rotating handle at its center.

[0012] As a further technical solution, it also includes,

[0013] A mold for producing a spherical hollow parking stone includes an inner support mechanism and a bracket with two interlocking halves. Each half of the bracket is provided with a spherical shell. The inner support mechanism is located inside the spherical shell. A forming space is formed between the inner wall of the spherical shell and the inner support mechanism. The forming space is shaped like a spherical hollow parking stone.

[0014] As a further technical solution

[0015] The inner support mechanism is an expandable support skeleton, on which a flexible inner membrane is fitted, and the inner wall of the spherical outer shell is covered with a flexible outer membrane.

[0016] As a further technical solution

[0017] The expansion support frame includes a mandrel, a sleeve, a positioning ring, multiple first straight connecting rods, multiple second straight connecting rods, multiple first curved connecting rods, and multiple second curved connecting rods. The mandrel and the positioning ring are both mounted on the bracket.

[0018] One end of the first straight connecting rod is hinged to the positioning ring, and the other end is hinged to one end of the first curved connecting rod. The other end of the first curved connecting rod is hinged to one end of the second curved connecting rod, and the other end of the second curved connecting rod is hinged to the end of the spindle.

[0019] The sleeve is slidably mounted on the mandrel, and one end of the second straight connecting rod is hinged to the hinge point of the first curved connecting rod and the second curved connecting rod, while the other end is hinged to the sleeve.

[0027] The working principle and beneficial effects of this invention are as follows: Traditional parking stones are mostly solid structures, which are heavy and cause significant difficulties in transportation. In this solution, the parking stone is a hollow structure and sealed with a base plate. In practical use, the hollow parking stone can be transported to the site first, and the filling can be completed on-site. The interior of the hollow parking stone can be filled with sand, construction waste, or soil for counterweight. After filling, the base plate is installed, and the locking blocks on the base plate are inserted into the locking grooves.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figures 1-6 As shown, this embodiment proposes a spherical hollow parking stone, including a base 1 and a sphere 2 connected in sequence. Both the base 1 and the sphere 2 are hollow structures. The inner wall of the base 1 has at least two slots 3, and it also includes a bottom plate 4. The bottom plate 4 has a locking block 5 for engaging with the slots 3. After the locking block 5 is engaged with the slots 3, the bottom plate 4 closes the base 1.

[0038] In this embodiment, traditional parking stones are mostly solid structures, which are heavy and cause significant difficulties in transportation. In this solution, the parking stones are hollow structures and sealed with a base plate 4. In actual use, the hollow parking stones can be transported to the site first, and the filling can be completed on-site. The interior of the hollow parking stones can be filled with sand, construction waste, or soil for counterweight. After filling, the base plate 4 is installed, and the locking blocks 5 on the base plate 4 are inserted into the locking grooves 3. Under the weight of the internal filling material, they achieve self-locking, thereby sealing the base 1. This facilitates transportation and meets weight requirements during use, preventing arbitrary removal.

[0039] Furthermore, it also includes,

[0040] There are three of each of the card blocks 5 and the card slots 3. The card blocks 5 are rectangular and the card slots 3 are L-shaped.

[0041] Furthermore, it also includes,

[0042] The card slot 3 includes an insertion section 6 and a snap-fit ​​section 7.

[0043] Furthermore, it also includes,

[0044] The base plate 4 has a rotating handle 8 at its center.

[0045] In this embodiment, the number of locking blocks 5 and locking slots 3 is preferably three. The locking blocks 5 are rectangular in shape, and the locking slots 3 include mutually perpendicular insertion sections 6 and locking sections 7. The insertion sections 6 and locking sections 7 form an "L" shape. The insertion sections 6 are parallel to the axial direction of the base 1, and the locking sections 7 are perpendicular to the axial direction of the base 1. The locking blocks 5 first enter the insertion sections 6, and then rotate the handle 8 to enter the locking sections 7, thereby achieving locking. Then, the weight of the internal filling material is used to lock the base plate 4, which is convenient and quick.

[0046] Furthermore, it also includes,

[0047] A mold for producing a spherical hollow parking stone includes an inner support mechanism and a bracket 9 with a two-part interlocking structure. Each of the two bracket halves is provided with a spherical shell 10. The inner support mechanism is located inside the spherical shell 10. A forming space is formed between the inner wall of the spherical shell 10 and the inner support mechanism. The forming space is shaped like a spherical hollow parking stone.

[0048] In this embodiment, after the two halves of the bracket 9 are fastened together, the two hemispherical shells 10 can be fastened together to form a complete sphere 2. The space between the spherical shell 10 and the internal support mechanism is a forming space. The shape of the forming space is the shape of the spherical hollow stop stone, which is used for grouting and finally formed into a spherical hollow stop stone.

[0049] Furthermore, it also includes,

[0050] The inner support mechanism is an expandable support frame 23, on which a flexible inner capsule 11 is fitted, and the inner wall of the spherical outer shell 10 is covered with a flexible outer capsule 12.

[0051] Furthermore, it also includes,

[0052] The expansion support frame 23 includes a spindle 13, a sleeve 14, a positioning ring 15, a plurality of first straight connecting rods 16, a plurality of second straight connecting rods 17, a plurality of first curved connecting rods 18 and a plurality of second curved connecting rods 19, wherein the spindle 13 and the positioning ring 15 are both disposed on the bracket 9;

[0053] One end of the first straight connecting rod 16 is hinged to the positioning ring 15, and the other end is hinged to one end of the first curved connecting rod 18. The other end of the first curved connecting rod 18 is hinged to one end of the second curved connecting rod 19, and the other end of the second curved connecting rod 19 is hinged to the end of the spindle 13.

[0054] The sleeve 14 is slidably disposed on the spindle 13, and one end of the second straight connecting rod 17 is hinged to the hinge point of the first curved connecting rod 18 and the second curved connecting rod 19, and the other end is hinged to the sleeve 14.

[0055] The flexible inner capsule 11 is sleeved on the first curved connecting rod 18 and the second curved connecting rod 19, and the first curved connecting rod 18 and the second curved connecting rod 19 form a spherical shape after unfolding.

[0056] In this embodiment, the expansion of the first curved connecting rod 18 and the second curved connecting rod 19 is controlled by the sliding sleeve 14, thereby supporting the flexible inner capsule 11 into a spherical shape. The bottom end of the mandrel 13 has a spherical disk, which smoothly transitions with the unfolded second curved connecting rod 19 to form a regular spherical shape. Specifically, firstly, the flexible outer capsule 12 is attached to the inner wall of the spherical outer shell 10. Then, the closed expansion support frame 23 is inserted into the spherical outer shell 10. Next, the sliding sleeve 14 is used to swing the second straight connecting rod 17 to support the hinge point of the first curved connecting rod 18 and the second curved connecting rod 19, so that the flexible inner capsule 11 forms a spherical shape, forming a molding space between it and the flexible outer capsule 12 for grouting. The flexible inner capsule 11 and the flexible outer capsule 12 are used to make the surface of the final product smoother and more regular, while ensuring that no grout leakage occurs during the grouting process. The spherical outer shell 10 is used to support the shape of the flexible outer capsule 12, and the expansion support frame 23 is used to support the shape of the flexible inner capsule 11, thereby controlling the final shape. After the product is formed, the sliding sleeve 14 closes the expansion support skeleton 23, making it easy to remove from the inside. Since the quality requirements for the appearance and smoothness of the internal contour of the sphere 2 are not high, the expansion support skeleton 23 adopts linear support, which is different from the surface support between the flexible outer membrane 12 and the spherical shell 10. By designing a special expansion support skeleton 23, the grouting and molding of the spherical hollow stop stone is realized. Furthermore, by designing the linkage structure of the sleeve 14 with multiple connecting rods and movable fulcrums, it can be easily removed from the sphere 2 after the product is formed. Finally, a production mold for a spherical hollow stop stone that is convenient and quick to operate and produces high-quality products is provided, which provides a good foundation for its production.

[0057] Furthermore, it also includes,

[0058] The bracket 9 is provided with a crossbeam 20, and the crossbeam 20 has a suspension groove 21. The positioning ring 15 is engaged in the suspension groove 21.

[0059] In this embodiment, the positioning ring 15 is inserted into the suspension groove 21 to achieve the positioning of the expansion support frame 23, ensuring the stability of the flexible inner membrane 11 during the grouting process and controlling the accuracy of the final product shape.

[0060] Furthermore, it also includes,

[0061] The mandrel 13 has a limiting ring 22.

[0062] In this embodiment, the limiting ring 22 on the mandrel 13 is used to limit the extreme position of the sleeve 14 sliding. When the sleeve 14 slides to the position that causes the expansion support skeleton 23 to be supported and the flexible inner capsule 11 to be supported into the required shape, the end of the sleeve 14 is located at the limiting ring 22 and abuts against it, thereby maintaining the shape of the flexible inner capsule 11 and ensuring the accuracy of the shape of the molded product.

[0063] Furthermore, it also includes,

[0064] Both the flexible outer capsule 12 and the flexible inner capsule 11 are made of latex.

[0065] In this embodiment, both the flexible outer capsule 12 and the flexible inner capsule 11 are made of latex material to make the outer surface of the final sphere 2 smooth and to prevent grout leakage during grouting.

[0066] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
