Description

Technical Field

[0001] This utility model relates to the field of ground pressure strip technology, specifically to a highly stable ground pressure strip. Background Technology

[0002] Floor strips are mainly used in floor construction, especially when laying floor tiles, carpets, flooring and other materials. They are used to transition the height difference between different floor materials, cover the joints and enhance the stability of the joints. The main function of floor strips is to reduce the impact of uneven pressure on the floor materials by evenly distributing the load, so that the floor materials are less likely to warp or loosen, thereby extending the service life of the floor materials.

[0003] Chinese Patent Publication No. CN208023900U discloses a floor trim strip, comprising: a fixed base, a floor cover, and a floor head connecting the fixed base and the floor cover. The floor cover includes a decorative strip and a first and second snap-fit ​​foot disposed on the decorative strip. The decorative strip has an arc-shaped plate structure, and the first and second snap-fit ​​feet are located on a concave side of the decorative strip, forming a connecting groove between the first and second snap-fit ​​feet and the decorative strip. The floor head includes a connecting post, a connecting head, and a connecting rib fixed between the connecting post and the connecting head. The connecting post is placed within a matching connecting groove. The fixed base includes a U-shaped bottom buckle and a base plate extending from the bottom of the U-shaped bottom buckle to one or both sides. The connecting head is placed within the U-shaped bottom buckle. This utility model has the advantages of simple structure, convenient installation and use, firm connection, and effective reduction of replacement costs.

[0004] The aforementioned patent proposes that the U-shaped bottom buckle of the fixed base of the floor strip has only a single set of first serrations on its inner side, while the connecting head of the floor strip has a single set of second serrations on its outer side. The two are connected by the meshing of the single set of serrations. This single-set meshing structure has a limited contact area, and the meshing surface of the single set of serrations is concentrated on a single transverse plane, without forming a multi-dimensional locking constraint. The connection stability depends entirely on the friction between the serrations and the elastic deformation of the material itself. Moreover, as a key component of the indoor floor joint, the floor strip needs to withstand the external forces such as people stepping on it and cleaning equipment rolling over it for a long time. Under continuous external force, the tips of the serrations are prone to deformation due to fatigue wear, which can easily lead to an increase in the meshing gap of the serrations. When the serrations wear and cause the connection to loosen, there will be lateral movement between the floor strip head and the fixed base, which will cause the floor strip cover to shift and cause the floor strip to fail. Therefore, we propose a highly stable floor strip. Utility Model Content

[0005] To address the aforementioned issues, a highly stable floor strip is provided. It achieves engagement through two sets of main locking grooves that mesh with corresponding main locking plates, ensuring uniform stress distribution between the second floor strip body and the two first floor strip bodies. This significantly slows down the fatigue wear rate of the locking teeth and prevents tooth breakage and floor strip body deformation caused by localized stress concentration. It solves the technical problem of the floor strip failing to form a multi-dimensional locking constraint, which easily leads to increased tooth meshing gaps under external forces, causing lateral movement between the floor strip head and the fixed base, resulting in floor strip malfunction.

[0006] To address the problems of existing technologies, this utility model provides a highly stable ground pressure strip, comprising a first ground pressure strip body, with second ground pressure strip bodies respectively disposed on both sides of the first ground pressure strip body. A cavity is formed in the first ground pressure strip body, and a reinforcing plate is fixedly connected within the cavity to enhance the structural strength of the first ground pressure strip body. A main locking plate is fixedly connected to the lower side of the first ground pressure strip body. A main locking groove is formed on the side of the second ground pressure strip body near the first ground pressure strip body, and the main locking groove engages with the main locking plate. A support and limiting mechanism is provided between the first and second ground pressure strip bodies to enhance the structural strength and constraint stability of the connection between the first and second ground pressure strip bodies.

[0007] Preferably, the supporting limiting mechanism includes a limiting plate and a guide component; the limiting plate is disposed below the main body of the first ground pressure strip; the guide component is disposed between the limiting plate and the main body of the second ground pressure strip, and the guide component is used to assist the limiting plate and the main body of the second ground pressure strip in positioning and splicing.

[0008] Preferably, the guide assembly includes a guide rail plate and a guide groove plate; the guide rail plate is fixedly connected to the side of the second ground pressure strip body near the limiting plate; the guide groove plate is fixedly connected to the outer side of the limiting plate, and the guide groove plate and the guide rail plate are slidably engaged.

[0009] Preferably, the guide rail plate and the guide groove plate form a sliding guide pair.

[0010] Preferably, the support limiting mechanism includes a first limiting component and a second limiting component; the first limiting component is disposed between the second ground pressure strip body and the limiting plate, and the first limiting component is used to strengthen the structural strength and constraint stability of the connection between the second ground pressure strip body and the guide plate; the second limiting component is disposed between the second ground pressure strip body and the limiting plate, and the second limiting component is used to strengthen the structural strength and constraint stability of the connection between the second ground pressure strip body and the limiting plate.

[0011] Preferably, the first limiting component includes a first locking plate and a first locking groove; the first locking plate is fixedly connected to the guide groove plate; the first locking groove is opened on the side of the second ground pressure strip body near the guide groove plate, and the first locking groove engages with the first locking plate.

[0012] Preferably, the second limiting component includes a second locking plate and a second locking groove; the second locking plate is fixedly connected to the side of the second ground pressure strip body near the limiting plate; the second locking groove is opened in the middle of the limiting plate, and the second locking groove engages with the second locking plate.

[0013] The advantages of this utility model compared to the prior art are:

[0014] 1. By using two sets of main tooth grooves to mesh with the corresponding main tooth plates, the locking and connection is achieved, ensuring that the connection stress between the second ground strip body and the two first ground strip bodies is evenly distributed. This can significantly slow down the fatigue wear rate of the tooth grooves, and at the same time avoid tooth breakage and deformation of the ground strip body caused by local stress concentration. This solves the technical problem that the floor strip does not form a multi-dimensional locking constraint, which easily leads to an increase in the tooth meshing gap under external force, and lateral movement between the floor strip head and the fixed base, causing the floor strip to fail.

[0015] 2. By using a reinforcing plate fixedly connected inside the cavity of the ground strip, the deformation resistance of the cavity structure can be enhanced, the structural stability can be maintained, and the cavity collapse or the main body bending can be avoided due to external impact. This solves the technical problem that the ground strip is prone to failure under external force because the cavity structure has insufficient deformation resistance, deformation leads to loose connection structure.

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] See Figures 1-3 As shown, a highly stable ground pressure strip includes a first ground pressure strip body 1, with second ground pressure strip bodies 11 respectively disposed on both sides of the first ground pressure strip body 1. A cavity is formed on the first ground pressure strip body 1, and a reinforcing plate 2 is fixedly connected inside the cavity of the first ground pressure strip body 1 to enhance the structural strength of the first ground pressure strip body 1. A main locking plate 21 is fixedly connected to the lower side of the first ground pressure strip body 1. A main locking groove 22 is formed on the side of the second ground pressure strip body 1 near the first ground pressure strip body 1, and the main locking groove 22 engages with the main locking plate 21. A support and limiting mechanism is provided between the first ground pressure strip body 1 and the second ground pressure strip body 11 to enhance the structural strength and constraint stability of the connection part of the first ground pressure strip body 1 and the second ground pressure strip body 11.

[0024] Specifically, a reinforcing plate 2 is fixedly connected inside the cavity of the first ground pressure strip body 1. The reinforcing plate 2 can enhance the deformation resistance of the cavity structure. When the first ground pressure strip body 1 is subjected to external force, it can maintain its own structural stability and avoid cavity collapse or body bending due to external impact.

[0025] When the first ground pressure strip body 1 and the second ground pressure strip body 11 are assembled, the main locking plate 21 and the main locking groove 22 engage through toothed meshing. The two sets of main locking grooves 22 respectively form symmetrical meshing with the corresponding main locking plates 21. Compared to the existing single-set sawtooth structure, the two sets of meshing points are symmetrically distributed along the axis of the second ground pressure strip body 11, forming a bidirectional symmetrical constraint. Unlike a single set of sawtooth that can only provide frictional constraint in a single transverse plane, the two sets of engaging structures, relying on a symmetrical layout, can achieve multi-dimensional locking in the radial and axial directions, further enhancing connection stability.

[0026] Meanwhile, the symmetrical connection between the two sets of main tooth grooves 22 and the main tooth plate 21 can evenly distribute external loads to the two sets of meshing structures, making the stress state more balanced. This uniform stress mode can significantly slow down the fatigue wear rate of the teeth and extend their service life; at the same time, it can avoid problems such as tooth breakage and deformation of the ground pressure strip body caused by local stress concentration, ensuring the long-term integrity of the overall structure of the ground pressure strip. Even if one set of teeth experiences slight wear, the other set of teeth can still maintain effective restraint and prevent the connection from loosening instantly.

[0027] In addition, uniform stress distribution can effectively prevent the main body of the floor strip from shifting, ensuring that the floor cover always fits tightly against the floor surface. This not only reliably covers the floor joints but also maintains good sealing performance, avoiding a chain reaction of functional failures caused by structural shifts. This ensures that the floor strip can play its core role in joint treatment, waterproofing, and dustproofing for a long time.

[0028] In addition, the support and limiting mechanism can enhance the structural strength of the connection parts of the two second ground pressure strip bodies 11, as well as the overall connection strength of the connection parts of the first ground pressure strip body 1 and the second ground pressure strip body 11, thereby further improving the overall stability and load-bearing capacity of the ground pressure strip after assembly.

[0029] See Figure 4 and Figure 5 As shown, the supporting and limiting mechanism includes a limiting plate 23 and a guide assembly; the limiting plate 23 is disposed below the first ground pressure strip body 1; the guide assembly is disposed between the limiting plate 23 and the second ground pressure strip body 11, and the guide assembly is used to assist the limiting plate 23 and the second ground pressure strip body 11 in positioning and splicing; the guide assembly includes a guide rail plate 24 and a guide groove plate 25; the guide rail plate 24 is fixedly connected to the side of the second ground pressure strip body 11 near the limiting plate 23; the guide groove plate 25 is fixedly connected to the outer side of the limiting plate 23, and the guide groove plate 25 and the guide rail plate 24 are slidably engaged; the guide rail plate 24 and the guide groove plate 25 form a sliding guide pair.

[0030] Specifically, when assembling the first ground pressure strip body 1 and the second ground pressure strip body 11, the limiting plate 23 is first placed between the two second ground pressure strip bodies 11. The limiting plate 23 is then pushed to allow the guide groove plate 25 and the guide rail plate 24 to slide and connect along a preset direction. Using the sliding guide pair formed by the guide rail plate 24 and the guide groove plate 25, the two second ground pressure strip bodies 11 are guided symmetrically to both sides of the limiting plate 23 via a preset sliding trajectory, achieving initial positioning of the second ground pressure strip bodies 11. After completing the above steps, the first ground pressure strip body 1 is connected to the two second ground pressure strip bodies 11. At this time, the main locking plate 21 and the main locking groove 22 can quickly and accurately engage and connect based on the initial positioning, ensuring overall assembly accuracy and efficiency.

[0031] See Figure 4 and Figure 5As shown, the supporting limiting mechanism includes a first limiting component and a second limiting component; the first limiting component is disposed between the second ground pressure strip body 11 and the limiting plate 23, and is used to strengthen the structural strength and constraint stability of the connection between the second ground pressure strip body 11 and the guide plate 25; the second limiting component is disposed between the second ground pressure strip body 11 and the limiting plate 23, and is used to strengthen the structural strength and constraint stability of the connection between the second ground pressure strip body 11 and the limiting plate 23; the first limiting component includes a first toothed plate. 26 and the first toothed groove 27; the first toothed plate 26 is fixedly connected to the guide plate 25; the first toothed groove 27 is opened on the side of the second ground pressure strip body 11 near the guide plate 25, and the first toothed groove 27 engages with the first toothed plate 26; the second limiting component includes a second toothed plate 28 and a second toothed groove 29; the second toothed plate 28 is fixedly connected to the side of the second ground pressure strip body 11 near the limiting plate 23; the second toothed groove 29 is opened in the middle of the limiting plate 23, and the second toothed groove 29 engages with the second toothed plate 28.

[0032] Specifically, when the main locking plate 21 and the main locking groove 22 engage, the first locking plate 26 and the first locking groove 27, and the second locking plate 28 and the second locking groove 29 simultaneously complete positioning and engagement, forming a multi-level constraint structure of main engagement and double auxiliary engagement. The tilt direction of the teeth on the first locking plate 26 is opposite to that on the second locking plate 28, thus creating a bidirectional force constraint.

[0033] With the reverse tilting tooth design, the two sets of limiting components can offset the external force borne by the connection between the first ground pressure strip body 1 and the second ground pressure strip body 11 from different directions, and disperse the stress to multiple engagement contact points, avoiding tooth wear or loosening of the connection caused by local stress concentration, further enhancing the overall stability and structural strength of the connection between the first ground pressure strip body 1 and the second ground pressure strip body 11, and ensuring the long-term reliability of the ground pressure strip after assembly.

[0034] Working principle: When the first ground pressure strip body 1 and the second ground pressure strip body 11 are assembled, the limiting plate 23 is first placed between the two second ground pressure strip bodies 11. With the help of the sliding guide pair formed by the guide rail plate 24 and the guide groove plate 25, the two second ground pressure strip bodies 11 are automatically and symmetrically distributed on both sides of the limiting plate 23. Then, the first ground pressure strip body 1 and the two second ground pressure strip bodies 11 are docked. At the same time, the first locking plate 26 and the first locking groove 27, and the second locking plate 28 and the second locking groove 29 are simultaneously positioned and engaged, forming a multi-level constraint structure of main engagement and double auxiliary engagement, thus completing the assembly of the ground pressure strip.

[0035] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
