Description

Technical Field

[0001] The utility model relates to the technical field of spliced ​​floors, in particular to a locking assembly of spliced ​​floors. Background Art

[0002] The spliced ​​floor generally includes a base plate and a decorative plate. The base plate is provided with a lock to splice the spliced ​​floors together, and the decorative plate is the surface that the user directly contacts. The main factors that determine the performance of the spliced ​​floor are the base plate and the lock. The structure and material selection of the base plate directly determine the performance and service life of the spliced ​​floor, and the design of the lock also seriously affects the convenience of splicing the spliced ​​floor and the stability after splicing. Therefore, the improvement of the spliced ​​floor in the prior art mainly focuses on the base plate and the lock.

[0003] There is a splicing floor in the prior art, which has male buckles on one pair of adjacent edges of the base plate, and female buckles on the other pair of adjacent edges. The male buckles of one splicing floor cooperate with the female buckles of another splicing floor to splice the two splicing floors. However, the male buckles and female buckles of the above-mentioned splicing floor are obtained by milling directly on the base plate. Since the contours of the male buckles and female buckles are complex and the dimensional accuracy requirements are high, high-precision cutting and milling equipment is required for cutting and milling during production, and the cost of purchasing production equipment is high. In addition, the splicing floor of the prior art generally uses stone powder as the base material, which has the disadvantage of being brittle. The male buckles or female buckles can be partially bent or broken by hand, resulting in local deformation, dark cracks or material falling due to bumps and other reasons during actual use, and the splicing cannot be completed. In addition, stone powder is water-absorbent. When there is water on the surface where it is laid, the water will penetrate into the splicing floor, causing the splicing floor to expand and deform, affecting the service life and user experience. The above problems can be solved if the base plate, male buckle and female buckle can be produced separately, and each uses a material that matches its functional requirements and has a higher cost-effectiveness. However, there are currently no similar products on the market, so it is necessary to improve the existing technology. Utility Model Content

[0014] The utility model provides a locking assembly for a spliced ​​floor. Compared with the prior art, the male and female buckles of the locking assembly are independent of the substrate structure, so that the materials thereof can be different from those of the substrate and other materials can be selected.

[0025] The following is a detailed description of the embodiments of the present utility model.

[0026] In this embodiment, unless otherwise clearly specified and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in this embodiment can be understood according to the specific circumstances. The directional words that appear in this embodiment are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of this embodiment changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0027] The utility model provides a locking assembly for splicing floors, such as Figures 1 to 6 As shown, it includes a male buckle 1 and a female buckle 2, the male buckle 1 includes a male base strip 12, the two ends of the male base strip 12 in the horizontal lateral direction are respectively a male buckle distal end 121 and a male buckle proximal end 122, the male buckle distal end 121 is that the end away from the substrate 01 after the male buckle 1 is installed on the substrate 01, the male buckle proximal end 122 is that the end close to the substrate 01 after the male buckle 1 is installed on the substrate 01, the male buckle 1 also includes a first male vertical strip 13 extending downward from the male buckle distal end 121 and a male top strip 14 extending laterally from the bottom end of the first male vertical strip 13 to the direction where the male buckle proximal end 122 is located, the first male vertical strip 13 and the male top strip 14 constitute a plug-in strip 11; the female buckle 2 includes a female base strip 22, the two ends of the female base strip 22 in the horizontal lateral direction are respectively a female buckle distal end 221 and a female buckle proximal end 222, the female buckle distal end 221 is that the female buckle proximal end 222 The buckle 2 is installed on the substrate 01, and the end away from the substrate 01 is the proximal end 222 of the female buckle, that is, the end close to the substrate 01 after the female buckle 2 is installed on the substrate 01. The female buckle 2 also includes a first female vertical bar 23 extending downward from the distal end 221 of the female buckle, a female horizontal bar 24 extending laterally from the bottom end of the first female vertical bar 23 to the direction away from the female base bar 22, a second female vertical bar 25 extending upward from the end of the female horizontal bar 24, and a female top bar 26 extending laterally from the top of the second female vertical bar 25 to the direction close to the female base bar 22. The first female vertical bar 23, the female horizontal bar 24, the second female vertical bar 25 and the female top bar 26 constitute a plug-in slot 21; when the male buckle 1 and the female buckle 2 are buckled together, the plug-in strip 11 is inserted into the plug-in slot 21, and the male top bar 14 is located below the female top bar 26 so that the male buckle 1 and the female buckle 2 are hooked with each other.

[0028] When producing the spliced ​​floor, the male buckle 1 is bonded to one pair of adjacent edges of the base plate 01, and the female buckle 2 is bonded to the other pair of adjacent edges of the base plate 01, and Figure 6As shown, the plug-in strip 11 of the male buckle 1 is located within the vertical projection of the base plate 01 and the plug-in groove 21 of the female buckle 2 extends out of the vertical projection of the base plate 01, so that a spliced ​​floor that can be spliced ​​with each other can be obtained.

[0029] Based on the above structural settings, such as Figure 6 As shown, when two pieces of splicing floor are spliced, the male top bar 14 is located below the female top bar 26, and the male top bar 14 abuts the female top bar 26, and the force of the male top bar 14 abutting the female top bar 26 has vertical and horizontal components, that is, the male top bar 14 and the female top bar 26 are hooked with each other, and based on the mutual hooking relationship, the male buckle 1 and the female buckle 2 can abut each other in both the horizontal and vertical directions without loosening. The above structure is used to realize the splicing of the male buckle 1 and the female buckle 2, and when two pieces of splicing floor are spliced, the male buckle 1 and the female buckle 2 form a force abutting each other in the vertical and horizontal directions, so that the male buckle 1 and the female buckle 2 will not loosen in both the vertical and horizontal directions, and the splicing floors are firmly spliced, especially in the face of thermal expansion and contraction, they can still be tightly buckled.

[0030] Since both the male buckle 1 and the female buckle 2 are profiles, the production method of the male buckle 1 and the female buckle 2 can be to first extrude a profile of indefinite length, and then cut it into the required size as needed to obtain the male buckle 1 and the female buckle 2, which is convenient to produce and has low production costs. Since the male buckle 1 and the female buckle 2 are both independent structures, their materials can be different from the substrate 01. Preferably, the male buckle 1 and the female buckle 2 are both aluminum profiles. Aluminum profiles have the advantages of convenient production, high strength, low thermal expansion and contraction rate, and are not easy to be corroded. They also have high dimensional accuracy and are not easy to be damaged, making the splicing structure of the spliced ​​floor durable and stable. Of course, it is also possible to use other metal materials or high-strength plastics such as engineering plastics to make the male buckle 1 and the female buckle 2, which should also fall within the protection scope of the present utility model.

[0031] In this embodiment, in the horizontal direction, the lateral distance W1 between the first female vertical bar 23 and the female top bar 26 is greater than the lateral width W2 of the whole formed by the first male vertical bar 13 and the male top bar 14. This arrangement ensures that neither of the plug-in strip 11 needs to be deformed when the plug-in slot 21 is inserted. However, such an arrangement will inevitably make the lateral distance W3 between the first female vertical bar 23 and the second female vertical bar 25 greater than W2, which will cause a gap to exist between the two after the plug-in strip 11 is fully inserted into the plug-in slot 21. This gap will cause the male buckle 1 and the female buckle 2 to loosen. For this reason, when designing the spliced ​​floor, the outer side surface of the first male vertical bar 13 should be retracted relative to the side surface of the substrate 01, and the outer side surface of the first female vertical bar 23 should be retracted relative to the side surface of the substrate 01; this design is to utilize the deformation of the substrate 01. Since the substrate 01 is made of non-metallic material, it is more susceptible to elastic deformation. Based on the above structural setting, when splicing, after the plug-in strip 11 is basically aligned with the plug-in slot 21, a force is applied downward from the upper side (usually a knocking force from top to bottom). The force only needs to cause the substrate 01 to shrink inward toward the middle of each horizontal part, and the shrinkage amount is such that the plug-in strip 11 can be aligned with the plug-in slot 21 and the plug-in strip 11 can enter the plug-in slot 21 from top to bottom. When the plug-in strip 11 is aligned with the plug-in slot 21, since W2 is smaller than W1, the plug-in strip 11 can easily enter the plug-in slot 21; and when the plug-in strip 11 is completely entered into the plug-in slot 21, The rebound of the base plate 01 will make the two spliced ​​floors move away from each other, and also make the male buckle 1 and the female buckle 2 move away from each other, and this process of moving away from each other can make the male top bar 14 press against the female top bar 26, and the above-mentioned rebound force makes the force of the male top bar 14 pressing against the female top bar 26 have vertical and horizontal components, so that the male buckle 1 and the female buckle 2 are buckled firmly, and the base plates 01 of the two spliced ​​floors will always keep pressing against each other under the restriction of the male buckle 1 and the female buckle 2, that is, the spliced ​​floors are tightly spliced, the seams will not increase, and the problem of seam expansion can be avoided even after long-term use.

[0032] In this embodiment, the depth H1 of the plug strip 11 extending downward from the male base strip 12 is less than the depth H2 of the plug slot 21 extending downward from the female base strip 22. Setting H1 to be less than H2 is to facilitate the plug strip 11 to be accommodated by the plug slot 21. If the two are set equal, once there is a size error, the plug strip 11 will not be able to be fully inserted into the plug slot 21.

[0033] In this embodiment, the male buckle 1 further includes a male buckle support portion extending downward from the male buckle proximal end 122, and the male buckle support portion includes two male support strips 15, and the plane formed by the bottom ends of the two male support strips 15 is parallel to the male base strip 12; the bottom end of the plug strip 11 is higher than the bottom ends of the two male support strips 15. The female buckle 2 also includes a female support strip 27 extending downward from the female buckle proximal end 222, and the bottom end of the female support strip 27 is in the same plane as the bottom surface of the female horizontal strip 24. In order to prevent the installation position of the male buckle 1 of the spliced ​​floor from being sunken, the male buckle 1 is provided with a male buckle support part, which is used to contact the laid ground surface and support the position of the spliced ​​floor where the male buckle 1 is installed; at the same time, the male buckle support part includes two male support bars 15, which has two advantages: one is to save materials, and the gap between the two male support bars 15 does not require materials, thereby reducing production costs; the second is to facilitate assembly, because when the male buckle 1 is bonded to the substrate 01, a certain pressure needs to be applied to the male buckle 1 to keep the male buckle 1 in the bonding position, and if only one male support bar 15 is provided, since the bottom end of the first male vertical bar 13 is higher than the bottom surface of the substrate 01, only one male support bar 15 will not be able to form a pressure-bearing plane, and if two male support bars 15 are provided, the bottom ends of the two male support bars 15 jointly form a pressure-bearing plane, so that the male buckle 1 will not fall over or tilt when the clamping force is applied. Similarly, the female support bar 27 is used to contact the laying surface and support the position of the spliced ​​floor where the female buckle 2 is installed. At the same time, the female support bar 27 and the female cross bar 24 also form a pressure-bearing plane, so that the female buckle 2 will not fall or tilt when the clamping force is applied.

[0034] In this embodiment, the male buckle 1 also includes a male positioning structure extending upward from the top surface of the male base strip 12, and the male positioning structure includes two male positioning strips 16, and the plane formed by the top ends of the two male positioning strips 16 is parallel to the male base strip 12. When assembling the spliced ​​floor, first open the bonding groove on the substrate 01, and insert the male positioning structure into the bonding groove when installing the male buckle 1, so that the male buckle 1 can be quickly positioned; at the same time, the gap between the male positioning strips 16 can also accommodate adhesives to improve the firmness of the bonding. The female buckle 2 also includes a female positioning structure extending upward from the top surface of the female base strip 22, and the female positioning structure includes two female positioning strips, and the plane formed by the top ends of the two female positioning strips is parallel to the female base strip 22. When assembling the spliced ​​floor, first open the bonding groove on the substrate 01, and insert the female positioning structure into the bonding groove when installing the female buckle 2, so that the female buckle 2 can be quickly positioned; at the same time, the gap between the female positioning strips can also accommodate adhesives to improve the firmness of the bonding.

[0035] In this embodiment, the total height H3 of the male buckle 1 is equal to the total height H4 of the female buckle 2 .

[0036] In summary, the locking assembly of the spliced ​​floor can make the spliced ​​structure of the spliced ​​floor durable and stable.

[0037] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the preferred technical solutions of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solutions of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the utility model.
