Description

Technical Field

[0001] This utility model relates to the field of chemical anchor technology, specifically a leak-proof chemical anchor. Background Technology

[0002] Chemical anchors, as a highly efficient and reliable connection technology, have been widely used in various fields such as civil engineering, construction, and machinery manufacturing. They work by injecting a chemical curing agent into pre-drilled holes, then inserting the anchor. The strong anchoring force is formed through a chemical reaction between the curing agent, the hole wall, and the anchor. This technology not only improves the overall stability and load-bearing capacity of the structure but also greatly simplifies the construction process and reduces construction costs.

[0003] However, in practical applications, the installation process of chemical anchors faces a problem that urgently needs to be solved: when the anchor is hammered or rotated into the borehole, the chemical curing agent inside the borehole is often partially squeezed out due to pressure, resulting in uneven distribution of the curing agent and affecting the anchoring effect. The extrusion of the curing agent not only reduces the anchoring force of the anchor but also causes environmental pollution and safety hazards. Therefore, a leak-proof chemical anchor is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a leak-proof chemical anchor to overcome the deficiencies of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A leak-proof chemical anchor includes a metal cylinder with three mounting ports on its outer wall arranged in a ring array, all extending to the bottom of the cylinder. A curing agent tube is movably installed inside the metal cylinder. Three glass protrusions are fixedly installed on the outer wall of the curing agent tube, corresponding to the three mounting ports. The three glass protrusions are connected to the curing agent tube through the port. A bottom cover is fitted onto the bottom of the metal cylinder. An anchor is fixedly installed inside the curing agent tube. A leak-proof ring is fixedly installed inside the metal cylinder near its top, and the anchor is movably installed inside the leak-proof ring. A hexagonal groove is formed at the top of the anchor.

[0007] The beneficial effects of this utility model are as follows: When in use, the chemical anchor is directly inserted into the drilled hole of the substrate. The anchor and the curing agent tube are rotated by using an external hex wrench. The glass protrusion on the outside of the curing agent tube breaks due to the rotation pressure, releasing the curing agent so that the anchor is bonded to the inside of the metal cylinder and flows out with the rotation, so that the metal cylinder is bonded to the drilled hole of the substrate. At the same time, the anti-leakage ring seals the top of the metal cylinder, which can effectively prevent the curing agent from leaking, thus ensuring the anchor fixing effect.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, an annular metal plate is fixedly installed on the outside of the metal cylinder, and multiple screws are installed on the annular metal plate, with the multiple screws distributed in a ring array on the annular metal plate.

[0010] Furthermore, a bottom plug is fixedly installed at the bottom of the inner cavity of the bottom cover. The bottom plug is located inside the metal cylinder, and the diameter of the bottom plug is larger than the inner diameter of the metal cylinder.

[0011] Furthermore, the top of the bottom plug is rounded, and the rounded diameter of the top of the bottom plug is smaller than the inner diameter of the metal cylinder.

[0012] Furthermore, the outer wall of the metal cylinder is fixedly fitted with threaded teeth. Attached Figure Description

[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] Example 1, as Figures 1-4 As shown, a leak-proof chemical anchor includes a metal cylinder 1. The outer wall of the metal cylinder 1 has three installation ports 2 arranged in a ring array. All three installation ports 2 extend to the bottom of the metal cylinder 1. A curing agent tube 4 is movably installed inside the metal cylinder 1. Three glass protrusions 5 are fixedly installed on the outside of the curing agent tube 4. The three glass protrusions 5 are correspondingly inserted into the three installation ports 2. The three glass protrusions 5 and the curing agent tube 4 are connected through each other. A bottom cover 6 is fitted onto the bottom of the metal cylinder 1. An anchor 7 is fixedly installed inside the curing agent tube 4. A leak-proof ring 8 is fixedly installed inside the metal cylinder 4 near its top. The anchor 7 is movably installed inside the leak-proof ring 8. A hexagonal groove 9 is formed on the top of the anchor 7.

[0021] By sealing the bottom of the metal cylinder 1 with the bottom cover 6, the hardener tube 4 and the glass protrusions 5 can be prevented from sliding off the bottom of the metal cylinder 1. The three glass protrusions 5 on the outer wall of the hardener tube 4 are installed inside the three mounting ports 2 on the outer wall of the metal cylinder 1. This not only limits the position of the hardener tube 4 but also increases the storage space for the hardener. In use, the chemical anchor can be directly inserted into the drilled hole in the substrate. Then, the operator can insert a hexagonal wrench into the hexagonal groove 9 to control the rotation of the anchor 7 and the hardener tube 4. Because the three glass protrusions 5 installed on the outer wall of the hardener tube 4... Since the three mounting ports 2 are not located inside the curing agent tube 4, when the curing agent tube 4 forcibly drives the three glass protrusions 5 to rotate, the three glass protrusions 5 will break under pressure. At this time, the curing agent inside the curing agent tube 4 and the glass protrusions 5 will flow out. The flowing curing agent can make the anchor bolt 7 adhere to the inside of the metal cylinder 1. As the anchor bolt 7 rotates, the curing agent flows through the three mounting ports 2 to the outside of the metal cylinder 1, which can make the metal cylinder 1 and the substrate drilled and adhered. At the same time as the anchor bolt 7 rotates, the top of the metal cylinder 1 is sealed by the anti-leakage ring 8, which can effectively prevent the curing agent from leaking from the top of the metal cylinder 1.

[0022] Example 2, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0023] An annular metal plate 10 is fixedly installed on the outside of the metal cylinder 1. Multiple screws 11 are installed on the annular metal plate 10, and the multiple screws 11 are distributed in a ring array on the annular metal plate 10.

[0024] With this setup, after inserting the chemical anchor into the drilled hole in the substrate, multiple screws 11 are driven through the annular metal plate 10 into the interior of the substrate to fix the metal cylinder 1. This not only prevents the anchor 7 from causing the metal cylinder 1 to rotate and slip, but also prevents the curing agent from flowing out between the metal cylinder 1 and the drilled hole in the substrate.

[0025] Example 3, as Figure 2 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0026] A bottom plug 12 is fixedly installed at the bottom of the inner cavity of the bottom cover 6. The bottom plug 12 is located inside the metal cylinder 1, and the diameter of the bottom plug 12 is larger than the inner diameter of the metal cylinder 1.

[0027] With this configuration, the bottom plug 12 will expand outward after being inserted into the metal cylinder 1. Under pressure, the bottom cover 6 can be more securely attached to the bottom of the metal cylinder 1.

[0028] Example 4, as Figure 2 As shown, this embodiment is a further improvement based on embodiment 3, and its specific details are as follows:

[0029] The top of the bottom plug 12 is rounded.

[0030] This design makes it easy for the bottom plug 12 to be inserted into the interior of the metal cylinder 1.

[0031] Example 5, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 2, and its specific details are as follows:

[0032] The outer wall of the metal cylinder 1 is fixedly fitted with threaded teeth 3.

[0033] This configuration allows the installed thread 3 to contact the curing agent, increasing the resistance of the metal cylinder 1 in the drilling of the substrate, thereby improving the stability of the metal cylinder 1 in the drilling of the substrate.

[0034] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
