Abstract

The invention is an embedded fixing screw, which is mainly used to firmly embed in objects (such as walls and granite materials) and lock the screws to hang or assemble other objects. By first placing the embedded body into the object, Then lock the push screw, so that the push bead pushes against the outer fixing bead and moves toward the outside of the bead hole provided in the insertion section of the embedded body, so that the outer fixing bead fixes the inside of the object and the embedded body is clamped on the object. After that, the screws can be locked into the threaded grooves, and finally other objects can be firmly connected or hung through the screws. Compared with the previous technology, the structure of the present invention can more stably place the embedded body on the object. In the body, even stone objects such as granite, granite walls or granite processing parts can be stably embedded inside and connected with screws.

Description

Embedded fixing screws

The invention relates to a screw that can be firmly embedded in granite or processed parts.

With the continuous improvement of the technology industry, the accuracy and stability required for the measurement, processing and equipment used are also more stringent. Therefore, because the compressive strength of granite is higher than other common materials, and it is consistent with Compared with metal materials (such as cast iron, steel and aluminum, etc.), granite not only has relatively high earthquake resistance, but also does not have the problem of rusting. Therefore, with the above advantages, granite Granite is recognized by the industry as an ideal application material for making high-precision testing instruments and process equipment.

Therefore, component platforms in the fields of precision processing and high-tech industries, including machine tools, semiconductor equipment, panel automatic optical inspection, circuit board drilling machines, laser equipment and coating equipment, etc., will all require granite or granite processing. Parts are used to achieve the assembly of the equipment, and in order to enable the granite or granite processing parts to support the combined components, screws are usually driven into the granite for fixation.

However, if screws are driven directly into granite or granite workpieces, the screws may break, uneven stress after the screws are locked, unstable screw fixation, and loosening of the internal structure of the granite components after assembly due to hole expansion. Problem, the above situation will not only cause the screws to be damaged, easy to bend and break, thereby shortening the service life of the screws, but also may cause structural damage to the granite or granite processing parts due to uneven internal force of the screws, thereby causing The safety of construction workers creates hidden dangers.

Therefore, before locking the screws on the granite stone, the expansion screws will first be driven into the granite stone, and then the screws will be locked into the expansion screws so that the screws can be firmly locked in the granite stone, and at the same time, the screws can be evenly aligned with the granite stone. Bear force to reduce damage to screws and granite.

However, although commercially available expansion screws have a good effect on common walls such as cement walls and wooden walls, on stone objects such as granite, the effect is still not good due to the material. In terms of durability, Has flaws.

Therefore, if the above problems can be optimized and improved, the durability and applicability of hanging objects hung on granite can be effectively increased.

The main purpose of the present invention is to provide an embedded fixing screw. By first placing the embedded body into an object (such as a wall, granite), and then locking the push screw, the push bead can be pushed against the outside. The fixing bead moves to the outside of the bead setting hole provided in the clamping section of the embedded body, allowing the outer fixing bead to fix the inside of the object and the inserting body to be clamped on the object. Then the screw can be locked into the threaded groove to secure the object. Can be hung firmly on screws.

In order to achieve the above objectives and effects, the present invention provides an embedded fixing screw, which includes an embedded body, an external fixing bead and a pushing screw. The embedded system includes a locking section and a clamping section, and the locking section is internally provided with a locking section. There is an axially penetrating threaded groove, and the locking section is provided with an axially penetrating accommodation groove. The threaded groove is communicated with the accommodation groove. The clamping section also has a lateral connection between the accommodation groove and the outside. The bead hole of space.

Furthermore, the external fixing bead is arranged in the bead setting hole, and the external fixing bead can be displaced in the space outside the accommodation groove and the bead setting hole, but the external fixing bead will not be able to escape outward from the bead setting hole.

Finally, the push screw includes an external thread on the circumferential side and a turn-in end and a combination end at both ends. The external thread is provided with the thread groove, and the turn-in end faces the outside of the locking section. The combination end The end is facing the locking section and is provided with a push bead, and the push screw can be displaced between the thread groove and the accommodating groove.

When the pushing screw is not screwed into the direction of the accommodating groove, and the pushing bead does not push against the outer fixing bead, the embedded fixing screw is in the first state. When the pushing screw is screwed into the direction of the accommodating groove, Screw it in and make the push bead push the outer fixing bead toward the outside of the bead setting hole, which is the second state of the embedded fixing screw.

In actual use, the user must first drive the embedded body into an object (such as a wall, granite), and then lock the pushing screw into the embedded body. The pushing bead of the pushing screw will lock the embedded body into the segment. The outer fixing bead is pushed to the outside of the embedded body and then firmly stuck in the object. Finally, the screw is locked into the threaded groove of the embedded body, and then the hanging object can be hung on the screw stably and durable.
