Description

Technical Field

[0001] This utility model relates to the field of wall tile installation technology, and in particular to a fastener for wall construction fastener installation. Background Technology

[0002] The installation of building wall tiles is undoubtedly a crucial and technically demanding part of the construction process. Traditional wall tile installation methods are complex, leading to high material and labor costs. In practice, many simplified installation techniques have emerged, and a large number of matching installation fasteners have appeared on the market. These simplified techniques have reduced construction costs.

[0003] Most existing construction fasteners are fixed to the wall using expansion bolts. The expansion bolt consists of a fixing screw with a nut and an expansion sleeve. In use, one end of the expansion bolt is placed in the installation hole, and the nut is turned with a tool to deform the expansion sleeve, so that its outer wall is pressed against the inner wall of the installation hole to form a fixation. This installation operation is relatively troublesome, resulting in low work efficiency. Therefore, this application provides a fastener for wall construction fastener installation to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a fastener for wall construction fastener installation, which solves the technical problem of low work efficiency caused by the cumbersome installation of existing expansion screws.

[0005] To achieve the above objectives, this application provides the following technical solution: a fastener for wall construction fastener installation, characterized in that: it includes a fixing screw for use with a nut, and the upper cavity of the fixing screw is provided with multiple sets of hook-shaped retaining springs in a circular pattern, and the hook of the hook-shaped retaining spring passes through a rectangular opening provided on the fixing screw and extends to the outside of the fixing screw.

[0006] In a preferred embodiment of this invention, multiple hook-shaped retaining rings are fixedly connected to the mounting block, and a tapered positioning block is fixed to the lower end of the mounting block. The inner cavity of the fixing screw is provided with a tapered positioning groove that is adapted to the tapered positioning block.

[0007] The upper end of the fixing screw is provided with a plug, which includes a sealing block, a threaded post with installation threads, and a pressing post connected together from top to bottom. The threaded post is threadedly connected to the inner wall of the fixing screw, and the lower end of the pressing post contacts the upper end of the mounting block.

[0008] In a preferred embodiment of this invention, the lower end of the fixing screw is provided with a rectangular block whose length is less than the outer diameter of the fixing screw, and rows of protrusions are provided on the outer walls of both sides of the rectangular block, the protrusions being adapted to the grooves provided at the clamping part of the pliers head.

[0009] In a preferred embodiment of this invention, the included angle T of the hook portion of the hook-shaped retaining ring is controlled between 30° and 45°.

[0010] In summary, the technical effects and advantages of this utility model are as follows:

[0011] This utility model has a reasonable structure and the fastener is easy and quick to install, which can greatly improve work efficiency.

[0012] In this invention, the hook-shaped retaining spring is detachably installed in the inner cavity of the fixing screw, allowing for the replacement of damaged hook-shaped retaining springs and reducing costs.

[0013] In this utility model, a rectangular block with protrusions is provided to facilitate the removal of the fixing screw from the mounting hole;

[0014] In this invention, the included angle T of the hook part of the hook-shaped retaining spring is controlled at 30~45°, which can avoid the poor hooking effect caused by the angle being too small, and at the same time prevent the hook-shaped retaining spring from being severely deformed and damaged when the fixing screw is inserted into the mounting hole due to the angle being too large.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Reference Figure 1-2 The wall construction fastener installation fastener shown is characterized in that: it includes a fixing screw 1 used in conjunction with a nut, and the upper cavity of the fixing screw 1 is provided with multiple sets of hook-shaped retaining springs 3 in a circular shape, and the hook of the hook-shaped retaining spring 3 passes through a rectangular opening 2 provided on the fixing screw 1 and extends to the outside of the fixing screw 1.

[0024] In use, the end of the fixing screw 1 with the hook-shaped retaining spring 3 can be directly inserted into the mounting hole. During this process, the hook of the hook-shaped retaining spring 3 will contact and be squeezed against the inner wall of the mounting hole. At this time, the hook-shaped retaining spring 3 will deform, causing the hook of the hook-shaped retaining spring 3 to move towards the inner cavity of the rectangular opening 2. Due to the elasticity of the hook-shaped retaining spring 3, the hook and the inner wall of the mounting hole will form a squeezing and resisting action. When the fixing screw 1 stops moving into the mounting hole, the raised end of its hook is in the position of the shape formed during movement. Within the groove, combined with the elastic force of the hook-shaped retaining spring 3, the fixing screw 1 is not easily rotated. At the same time, when the fixing screw 1 wants to move outward, the hook of the hook-shaped retaining spring 3 hooks into the wall like a hook (the raised end of the hook abuts against the inner wall of the mounting hole, and when the fixing screw 1 wants to move outward, its raised end tends to open outward, thus blocking the fixing screw 1 from moving outward), making it impossible for the fixing screw 1 to move outward. This fastener is easy and quick to install, which can greatly improve work efficiency.

[0025] As a preferred embodiment of this example, Figure 2 and Figure 3 As shown, multiple hook-shaped retaining rings 3 are fixedly connected to the mounting block 7. A conical positioning block 8 is fixed to the lower end of the mounting block 7. The inner cavity of the fixing screw 1 is provided with a conical positioning groove 9 that is adapted to the conical positioning block 8.

[0026] The upper end of the fixing screw 1 is provided with a plug, which includes a sealing block 4, a threaded post 5 with mounting threads 6 and a pressing post 10 connected together from top to bottom. The threaded post 5 is threadedly connected to the inner wall of the fixing screw 1, and the lower end of the pressing post 10 contacts the upper end of the mounting block 7.

[0027] When the fixing screw 1 moves outward by force, the hook part of the hook-shaped retaining spring 3 may be severely deformed and damaged. After the fixing screw 1 is removed from the mounting hole, the sealing block 4 can be removed and the internal hook-shaped retaining spring 3 can be replaced.

[0028] After placing multiple new hook-shaped retaining rings 3 into the mounting cavity of the fixing screw 1, the hook-shaped retaining rings 3 are positioned by the cooperation of the conical positioning block 8 and the conical positioning groove 9. Then, the pressing column 10 is pressed into contact with the upper end of the mounting block 7 to achieve the positioning of the hook-shaped retaining rings 3. This positioning setting is conducive to the hooks of multiple hook-shaped retaining rings 3 forming a pressing contact with the inner wall of the mounting hole, thereby achieving a good fixing effect on the fixing screw 1.

[0029] As a preferred embodiment of this example, Figure 4 As shown, the lower end of the fixing screw 1 is provided with a rectangular block 12 whose length is less than the outer diameter of the fixing screw 1, and rows of protrusions 11 are provided on the outer walls on both sides of the rectangular block 12. The protrusions 11 are adapted to the grooves provided at the clamping part of the pliers head.

[0030] The rectangular block 12 can be clamped with pliers and pulled backward to move the fixing screw 1 out of the mounting hole, making it easier to move the fixing screw 1 out of the mounting hole.

[0031] When inserting the fixing screw 1 into the mounting hole, the end of the rectangular block 12 can be hammered with a tool to drive the fixing screw 1 into the mounting hole.

[0032] As a preferred embodiment of this example, Figure 5 As shown, the included angle T of the hook portion of the hook-shaped retaining ring 3 is controlled between 30° and 45°.

[0033] Within this angle range, it avoids the hook's poor hooking effect due to an excessively small angle (poor hooking effect makes it easy for the fixing screw 1 to move outward, and also reduces the squeezing force between the hook and the inner wall of the mounting hole, thus affecting the fixing effect), while also preventing the hook-shaped retaining spring 3 from being severely deformed and damaged when the fixing screw 1 is inserted into the mounting hole due to an excessively large angle.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
