Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary tools for building decoration, specifically to an anti-slip positioning cross clip for tile laying. Background Technology
[0002] In interior and exterior tile laying projects, to ensure uniform and aesthetically pleasing gaps between tiles and to leave consistent space for subsequent grout sealing, tile setters commonly use tile positioning clips. Existing positioning clips typically consist of a cross-shaped frame and clip heads at the ends.
[0003] While existing positioning clips can meet basic positioning needs, they still have significant drawbacks: First, the smooth surface of traditional clips makes them prone to horizontal sliding or vertical floating during installation due to cement mortar flow, vibration, or worker foot traffic, resulting in inconsistent tile gap widths and affecting installation accuracy. Second, the clips lack effective support and can easily sink into excessively thick mortar under the pressure of the tiles, causing the actual gap depth to become shallower, affecting the adhesion of the grout, or even becoming completely buried and difficult to remove. Third, to ensure a secure hold, the clip heads are usually designed with a symmetrical structure, which, while preventing slippage, also makes removal difficult. Forcibly prying out the clips after the mortar has partially hardened can easily cause the clip heads to break, chipping the edges of the gap, or shifting already installed tiles. Therefore, there is an urgent need for positioning clips that can effectively prevent slippage, provide stable support, and be easily removed without damaging the tiles. Utility Model Content
[0004] The purpose of this utility model is to overcome the above-mentioned defects of the prior art and provide a non-slip tile laying positioning cross clip. Through structural improvement, it effectively solves the problems of slippage and sinking during the laying process and achieves convenient and damage-free removal.
[0005] The technical solution provided by this utility model is an anti-slip positioning cross clip for tile laying, including a central part, at least two positioning ribs extending outward from the central part, and the ends of the positioning ribs are formed with clip heads for locking into the tile gaps.
[0006] The positioning rib has multiple anti-slip protrusions on both sides;
[0007] Below the center part is an integrally formed support structure, the bottom height of which is lower than the bottom height of the card head.
[0008] As a preferred technical solution of this utility model, the support structure is a frustum, truncated pyramid, or cylindrical structure extending downward from the center, which is used to insert downward into the mortar below the tile.
[0009] As a preferred technical solution of this utility model, a limiting disk with a diameter larger than that of the center is provided between the bottom of the center and the supporting structure, which is used to limit the insertion depth of the supporting structure.
[0010] As a preferred technical solution of this utility model, the anti-slip protrusions are wavy, hemispherical or pyramidal, and are distributed at intervals along the length direction of the positioning rib. The outer surface of the anti-slip protrusions is flush with the two sides of the card head, and the friction with the adjacent tiles is increased by the anti-slip protrusions on both sides.
[0011] As a preferred embodiment of this utility model, the cross-section of the card head is trapezoidal, triangular, or arc-shaped.
[0012] As a preferred technical solution of this utility model, the bottom of the card head is provided with a shrinking slope near the inner side of the adjacent tile, and the top of the card head is provided with a guide slope near the outer side of the adjacent tile. The inclination angle of the shrinking slope is greater than the inclination angle of the guide slope.
[0013] As a preferred embodiment of this utility model, the number of positioning ribs is four, and they are evenly distributed in a cross shape.
[0014] As a preferred embodiment of this utility model, the central part, the card head, the anti-slip protrusion and the supporting structure are integrally injection molded from plastic, and the plastic is at least one of polyethylene, polypropylene or ABS engineering plastic.
[0015] The advantages of this utility model compared with the prior art are as follows:
[0016] 1. Excellent anti-slip performance: By setting anti-slip protrusions on both sides of the positioning rib, the friction with the side of the adjacent tile is greatly increased, which effectively prevents the horizontal sliding and vertical floating of the cross clip during the laying process and ensures the precise consistency of the gap width.
[0017] 2. Stable support effect: The one-piece molded support structure contacts the mortar base before the clip head, providing a stable base and preventing the entire cross clip from sinking too deep or being buried due to the pressure of the tiles. This ensures that all gaps are of uniform depth and facilitates later removal.
[0018] 3. Convenient removal method: The asymmetrical design of the clip head, with its inner constricting bevel, provides a force point for the tool. When removing the clip, you can deform it by squeezing it inward, thus easily removing the cross clip from the gap and greatly reducing the risk of damaging the edge of the tile.
[0019] 4. Simple structure and low cost: This utility model is an improvement on the traditional cross clamp. It has a simple structure, is easy to mass-produce through injection molding, has good corrosion resistance and reusability, and reduces construction costs. Attached Figure Description

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0028] Example 1:
[0029] As per the instruction manual Figure 1-4 As shown, the present invention provides an anti-slip positioning cross clip for tile laying, including a central part 1, at least two positioning ribs 2 extending outward from the central part 1, and the ends of the positioning ribs 2 forming clip heads 3 for locking into the tile gaps.
[0030] In this embodiment, the central part 1 is a cylindrical structure with a diameter of 2-3 mm, providing good rigidity. Four positioning ribs 2 radiate outward from the central part 1, evenly distributed in a cross shape (adjacent angles are 90°). The width of the positioning ribs 2 is smaller than the width of the clamp head 3, reducing the contact area with the mortar. The anti-slip protrusions 4 on the sides of the positioning ribs 2 are wavy, and are arranged every 8 mm along the length direction, with equal spacing between adjacent protrusions, providing a continuous anti-slip effect.
[0031] In this embodiment, the clamp 3 formed at the end of the positioning rib 2 has a trapezoidal cross-section, suitable for common tile gaps. The clamp 3 has a contraction slope 7 (tilt angle 70°) on both sides of the bottom and a guide slope 8 (tilt angle 45°) on both sides of the top. The guide slope 8 guides adjacent tiles to be laid on one side of the clamp 3 for alignment.
[0032] In this embodiment, an integrally formed frustum-shaped support structure 5 is located below the central part 1. The diameter of the upper bottom surface is equal to the side length of the central part 1, the diameter of the lower bottom surface is 4mm, and the height is 8mm, which facilitates the insertion of mortar. A limiting plate 6 with a diameter of 7mm and a thickness of 1.5mm is provided between the bottom of the central part 1 and the support structure 5. When the support structure 5 is inserted into the mortar until the limiting plate 6 contacts the surface of the tile, the insertion depth is 8mm. At this time, the bottom of the clamp 3 is located 1.5mm above the support plate, and stable support is provided by the limiting plate 6 and the support structure 5.
[0033] In this embodiment, the cross clip is integrally injection molded from polyethylene (PE). PE has good corrosion resistance and flexibility, making it suitable for humid environments. There are no gaps between the components, resulting in high structural strength and allowing it to be reused more than 5 times.
[0034] Working principle
[0035] During installation, place the clip 3 of this cross clip on the edge of the laid tile, then place the adjacent tile against it and press the center 1 to insert the support structure 5 into the mortar below. When the limiting plate 6 contacts the tile surface, the insertion depth reaches the preset value, and pressing stops. At this point, the clip 3 is fully inserted into the gap, and the anti-slip protrusions 4 on the side of the positioning rib 2 are in close contact with the adjacent tile, generating friction. The guide slope 8 guides the placement of the adjacent tile. Through the above structure, the cross clip fixes the tile position and prevents displacement due to external force or mortar flow. After the mortar solidifies, insert a small scraper into the bottom of the clip 3 from the inside of the gap and gently pry it upwards and inwards. Using the guide of the inner contraction slope 7 of the clip 3, the clip 3 contracts and deforms inwards, thus detaching from the hook of the tile. The entire cross clip can be easily removed, cleaned, and reused.
[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
