Description

TECHNICAL FIELD

[0001] The utility model relates to panel assembly technical field, concretely relates to a panel assembly component convenient to fix and install. BACKGROUND

[0002] Wall decoration is a very important link in the process of interior decoration, and the commonly used wall decoration materials include panel and paint, wherein the panel is classified as ceramic tile, stone slab and rock slab. The traditional panel such as ceramic tile with small area can be pasted by the traditional method, that is, the ceramic tile is adhered to the wall surface through concrete. However, for the large area wall brick which is popular at present, such as television background wall, it is difficult to realize stable adhesion and fixation by the traditional concrete adhesion method. Generally, the large panel on the wall usually needs to install a steel frame on the wall first, and then fix the ceramic tile on the frame through back buckle. The common wall panel mounting method includes two kinds, which are as follows: (1) punch back bolt hole on the panel, pass the back bolt through the back bolt hole and fix the ceramic tile on the steel frame. The advantage of this fixing method is good fixing effect, and the disadvantage is that the appearance consistency and beauty of the panel are reduced. (2) groove is opened on the back of the panel, the panel is fixed on the steel frame by embedding the fixing piece into the groove to prevent the panel from moving vertically, and then the panel is fixed on the steel frame by means of adhesive to prevent the panel from moving horizontally. The advantage of this fixing method is that the overall consistency and beauty of the panel are maintained, and the disadvantage is that the fixing effect is poor. Therefore, there is no panel assembly component on the market which can consider the fixing effect and installation beauty of the panel. SUMMARY

[0003] Therefore, the utility model provides a panel assembly component convenient to fix and install to solve the problem that the fixing effect and installation beauty of the panel cannot be considered in the process of fixing and installing the panel.

[0004] The utility model provides a panel assembly component convenient to fix and install, which comprises panel and fixed component, the back of the panel is equipped with positioning groove, the positioning groove is arranged to be inclined from the surface to the inside, and the fixed component is arranged to be connected with external structure.

[0005] The fixed component comprises positioning claw matched with the positioning groove, and the positioning claw is arranged to be inclined.

[0006] When the panel is fixed and installed, the positioning claw is embedded into the positioning groove to fasten the positioning groove.

[0007] The utility model discloses a plate assembly subassembly convenient to fix and install includes board and fixed subassembly, wherein the back of board is equipped with the inclined setting locating groove from the table to the inside, and fixed subassembly includes the inclined setting locating claw that coordinates with locating groove. When installing the fixed plate, the locating claw is embedded in the locating groove, and since the locating claw and the locating groove are all inclined setting, the locating claw cannot directly exit from the locating groove, can effectively prevent the fixed subassembly from being disconnected with the board, and the fixing effect of the board is enhanced. In addition, since the locating groove is arranged on the back of the board (the surface for paving is also the opposite surface of the decorative surface), and does not penetrate the board, the decorative effect of the board will not be affected. Further, the fixed subassembly is connected with other external structures, facilitating the installation of the board and other external structures.

[0008] In a specific embodiment, the locating groove is circular in the cross section of the board, and the diameter of the circular shape gradually decreases from the surface to the inside of each cross section;

[0009] The fixed subassembly includes at least two locating claws, which divide the locating groove into equal-length circular arcs when embedded in the locating groove. Thus, the locating groove is circular as a whole, and the diameter of the circular shape gradually decreases from the surface to the inside of each cross section, i.e., the locating groove is inclined from the surface to the inside towards the middle position. Similarly, the at least two locating claws are inclined towards the middle position, and when the at least two locating claws are embedded in the locating groove, the locating groove is divided into equal-length circular arcs, ensuring that the locating claws tightly fasten the locating groove when embedded in the locating groove, effectively preventing the board from being detached from the fixed subassembly.

[0010] In a specific embodiment, the fixed subassembly includes a claw-shaped buckle, which includes a horizontally arranged base and a vertically arranged elastic plate connected to the edge of the base;

[0011] The base is circular, and the elastic plate is arranged equidistantly along the edge of the base;

[0012] The locating claws are arranged one-to-one on the end of the elastic plate away from the base, and the distance from the end of the elastic plate away from the base to the center axis is greater than the distance from the end of the elastic plate close to the base to the center axis, and the distance from the end of the locating claw away from the base to the center axis is less than the distance from the end of the locating claw close to the base to the center axis. Thus, the base, the elastic plate, and the locating claw together form the fixed subassembly, the elastic plate and the locating claw are arranged equidistantly along the edge of the circular base, and the elastic plate is arranged in an explosive manner away from the center axis, and the locating claw is arranged in a contracted manner towards the center axis. The elastic plate arranged in an explosive manner and the locating claw arranged in a contracted manner form a pincer structure, which tightly holds the locating groove, effectively preventing the locating claw from falling out of the locating groove. During the specific installation process, the position of the elastic plate and the locating claw can also be adjusted through the elastic plate, thereby adjusting the pincer structure to be in a tight or loose state, and thereby tightly or loosely holding the board.

[0013] In a specific embodiment, the fixing assembly further comprises a metal ring, a distance from an end of the elastic plate close to the base to the central axis is r1, a distance from an end of the elastic plate far from the base to the central axis is r2, and R is greater than r1 and less than r2;

[0014] When the fixing plate is fixed, the metal ring is sleeved with the claw-shaped buckle from the end of the base, so that the elastic plate and the positioning claw are contracted towards the central axis. When the fixing plate is fixed, the distance from the end of the elastic plate close to the base to the central axis is less than the radius of the metal ring, so that the metal ring can be easily sleeved with the claw-shaped buckle from the end of the base. Moreover, the distance from the end of the elastic plate far from the base to the central axis is greater than the radius of the metal ring, so that the metal ring is clamped with the elastic plate and presses the elastic plate when the metal ring moves towards the positioning claw. The pressed elastic plate moves in a contracting manner to tighten the pincers structure, so as to tightly buckle the positioning groove.

[0015] In a specific embodiment, the base is provided with a central hole, and the central hole is used to connect an external structure. In this way, the fixing plate and the fixing assembly can be fixed by penetrating the central hole with a fixing rod.

[0016] In a specific embodiment, the base is further provided with a nut, and a screw hole of the nut is consistent with and communicates with the central hole. By the communication between the nut and the central hole, the screw rod in the external structure can be connected with the fixing assembly, thereby fixing the plate.

[0017] In a specific embodiment, the number of the positioning claws and the elastic plates is 4, 5, 6, 7, 8, 9 or 10. The positioning claws and the elastic plates are distributed at equal distances along the circular positioning groove, which can effectively buckle the positioning groove and prevent the plate from falling off in the horizontal or vertical direction.

[0018] In another specific embodiment, the positioning groove presents a circular shape in the cross section of the plate, and the diameter of the circular shape gradually increases from the surface to the inside.

[0019] The fixing assembly comprises at least two positioning claws, and when the at least two positioning claws are embedded in the positioning groove, the positioning groove is divided into equal-length circular arcs. In this way, the positioning groove as a whole presents a circular shape, and the diameter of the circular shape gradually increases from the surface to the inside, that is, the positioning groove as a whole is inclined in the centrifugal direction from the surface to the inside. Similarly, the at least two positioning claws are arranged in an explosive manner in the centrifugal direction, and when the at least two positioning claws are embedded in the positioning groove, the positioning groove is divided into equal-length circular arcs, which ensures that the positioning claws buckle the positioning groove when the positioning claws are embedded in the positioning groove, thereby effectively preventing the plate from being loosened from the fixing assembly.

[0020] In another specific embodiment, the positioning groove presents a plurality of circular arcs in the cross section of the plate, and the plurality of circular arcs are distributed at equal distances along the outer periphery of the circular shape. The diameter of the circular shape corresponding to the plurality of circular arcs gradually decreases from the surface to the inside.

[0021] The fixing component includes positioning claws corresponding to the number of arcs. When the positioning claws are inserted into the positioning groove, they secure the positioning groove. Thus, the positioning groove is composed of multiple arc-shaped grooves arranged circumferentially, with these grooves evenly spaced. The positioning groove and positioning claws are inclined in the same direction. When a sheet material needs to be installed, inserting the positioning claws into the positioning groove effectively secures the sheet material and prevents it from loosening.

[0022] In a specific implementation, the material is a ceramic tile, stone slab, glass, or rock slab.

[0023] The advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description or may be learned by practice of the embodiments of this invention. Attached Figure Description

[0029] The following describes the preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.

[0030] The utility model provides a kind of plate assembly component convenient to fix and install, including plate and fixed component. Wherein plate can be any one of ceramic tile, stone slab, glass or rock slab, fixed component is used to connect with plate back (i.e. for the face of laying, with decorative surface opposite) to fix and install plate, for example, as intermediate connecting piece plate is connected with external structure. Plate back is equipped with locating groove, and locating groove is inclined from surface to inside, that is, locating groove is not perpendicular to back surface from surface to inside, but presents certain inclination angle;Similarly, fixed component includes locating claw matched with locating groove, and locating claw is also inclined. When fixing and installing plate, locating claw is embedded in locating groove, since locating claw and locating groove are all inclined, locating claw is blocked by locating groove side wall and cannot directly exit locating groove, which can effectively prevent fixed component from being disconnected with plate.

[0031] In a specific embodiment, the locating groove presents a circular shape in the cross-section of the plate, and the diameter of the circular shape gradually decreases from the surface to the inside of each cross-section, that is, the cross-section of the locating groove presents a circular ring shape, and the diameter of the circular ring gradually decreases from the surface to the inside of each cross-section, so that the locating groove is inclined from the surface to the center. The fixed component includes at least two locating claws, and the at least two locating claws divide the locating groove into equal-length circular arcs when embedded in the locating groove. The at least two locating claws can better tighten the locating groove and the plate, and the equal-distance distribution of the locating claws along the circular locating groove can better balance the lateral force of the plate, further tightening the plate.

[0032] In a specific embodiment, the fixed component includes a claw-shaped buckle, which includes a horizontally arranged base and a vertically arranged elastic plate connected to the edge of the base. The base and the elastic plate are assembled into a "cover" shape structure, and the opening of the "cover" shape structure faces the locating groove and covers the locating groove. The base is circular, and the elastic plate is arranged equidistantly along the edge of the base, so that the locating groove is divided into equal-length circular arcs when the locating claw is embedded in the locating groove. In this embodiment, the center axis of the "cover" shape structure passes through the center of the base and the center of the locating groove, the distance from the end of the elastic plate away from the base to the center axis is greater than the distance from the end of the elastic plate close to the base to the center axis, and the distance from the end of the locating claw away from the base to the center axis is less than the distance from the end of the locating claw close to the base to the center axis.

[0033] In a specific embodiment, the fixed component further includes a metal ring, the radius of the metal ring is R, the distance from the end of the elastic plate close to the base to the center axis is r1, and the distance from the end of the elastic plate away from the base to the center axis is r2, R is greater than r1 and less than r2. When fixing and installing the plate, the metal ring is sleeved with the claw-shaped buckle from the base end to make the elastic plate and the locating claw shrink towards the center axis.

[0034] In a specific implementation, the base is provided with a central hole, which is used to connect to an external structure, for example, by means of a screw or a pin.

[0035] In a specific implementation, the base is also provided with a nut, the screw hole of which is the same size as the central hole and is connected, making it more convenient and stable to connect with the external structure through the nut.

[0036] In specific implementations, the number of positioning claws and elastic plates is 2, 3, 4, 5, 6, 7, 8, 9, or 10. Among these, 3, 4, 5, 6, 7, or 8 are optimal.

[0037] In another specific embodiment, the positioning groove is circular on the cross-section of the board, and the diameter of the circle gradually increases from the outside to the inside, that is, the diameter of the circle on the cross-section gradually increases from the outside to the inside. The fixing component includes at least two positioning claws, which, when inserted into the positioning groove, divide the positioning groove into arcs of equal length. Thus, the positioning claws, during installation, are similar to expansion screws opening and then inserting into the positioning groove, achieving the effect of fixing the board.

[0038] In another specific embodiment, the positioning groove is presented as several arcs on the cross-section of the sheet metal, and the several arcs are evenly distributed along the outer circumference of a circle. The diameter of the circle corresponding to the several arcs gradually decreases from the outside to the inside. Unlike the circular positioning groove in the previous embodiment, the positioning groove here is several arc grooves evenly distributed along the outer circumference of a circle. The fixing component includes positioning claws corresponding to the number of arcs, which engage with the positioning groove to lock the positioning groove in place.

[0039] Example 1

[0040] like Figure 1 As shown, this is a specific embodiment of a sheet metal assembly that facilitates fixing and installation. This assembly includes a sheet metal 1 and a fixing component 2, the latter used to connect to an external structure. Figure 2 As shown, the back of the board 1 is provided with a positioning groove 11, which is inclined from the outside in (i.e., inclined towards the middle from top to bottom). The fixing component 2 is fixedly connected to the board 1 through the positioning groove 11. The fixing component 2 includes a positioning claw 21 that matches the positioning groove 11, and the positioning claw 21 is set with the same inclination as the positioning groove 11. When fixing the board 1, the positioning claw 21 is inserted into the positioning groove 11. At this time, the positioning claw 21 is locked into the positioning groove 11. Since the positioning claw 21 cannot be directly withdrawn from the positioning groove 11, it plays the role of fixing the board 1. Furthermore, since the positioning groove 11 does not penetrate the board 1, the fixing component 2 does not affect the decorative effect of the board's decorative surface when fixing the board 1.

[0041] In the present embodiment, the panel 1 can be a ceramic tile, and in other embodiments, the panel 1 can also be a stone panel or a rock panel.

[0042] In the present embodiment, the positioning groove 11 is circular in the cross section of the panel 1, and the diameter of the circular shape gradually decreases from the top to the bottom of each cross section, i.e., the positioning groove 11 is inclined towards the middle and extends to the inner layer of the panel 1. The fixing assembly 2 includes at least two positioning claws 21, for example, 2, 3, 4, 5, 6, 7, 8, 9 or 10. Among them, 3, 4, 5, 6, 7 or 8 is the best. In the present embodiment, the number of positioning claws 21 is two, and when the two positioning claws 21 are embedded in the positioning groove 11, the positioning groove 11 is divided into equal-length circular arcs, i.e., two semicircular arcs. Through the inclined arrangement of the positioning groove 11 from top to bottom and the equal-interval arrangement of the positioning claws 21, the positioning claws 21 can be effectively prevented from directly exiting the positioning groove 11, and the horizontal force acting on the fixing assembly 2 can be balanced, thereby strengthening the fixed connection effect. In other embodiments, the positioning groove 11 can also be other shapes in the cross section of the panel 1, which can also play a role in buckling the positioning groove 11.

[0043] In the present embodiment, as shown in Figure 3 The fixing assembly 2 includes a claw-shaped buckle 22. The claw-shaped buckle 22 includes a horizontally arranged base 221 and a vertically arranged elastic plate 222, and the elastic plate 222 is connected with the edge of the base 221. The base 221 is circular, and the elastic plate 222 is arranged equidistantly along the edge of the base 221. Thus, the elastic plate 222 and the base 221 together form a “cover” structure, and the opening of the “cover” structure faces the positioning groove and covers the positioning groove. The base 221 is circular, and the elastic plate 222 is arranged equidistantly along the edge of the base, thereby ensuring that when the positioning claw 21 is embedded in the positioning groove 11, the positioning groove 11 is divided into equal-length circular arcs. In the present embodiment, the central axis P of the “cover” structure passes through the center of the base 221 and the center of the positioning groove 11, the distance from the lower end of the elastic plate 222 to the central axis P is greater than the distance from the upper end of the elastic plate 222 to the central axis P, and the distance from the upper end of the positioning claw 21 to the central axis P is greater than the distance from the lower end of the positioning claw 21 to the central axis P. The elastic plate 222 is arranged in an explosive manner away from the central axis P, and the positioning claw 21 is arranged in a contraction manner towards the central axis. The explosive arrangement of the elastic plate 222 and the contraction arrangement of the positioning claw 21 form a pincer structure, which buckles the positioning groove 11 and effectively prevents the positioning claw 21 from falling off the positioning groove 11. In use, by adjusting the positions of the elastic plate 222 and the positioning claw 21, the pincer structure can be adjusted to be in a clamping or loosening state. In other embodiments, the base 221 and the positioning groove 11 can not be circular, or the base 221 and the positioning groove 11 are both circular but the centers are not on the same vertical axis, which can all ensure that the pincer structure buckles the positioning groove 11.

[0044] In the embodiment, as shown in Figure 2 The fixing assembly 2 further comprises a metal ring 23, the radius of the metal ring 23 is R, the distance from the upper end of the elastic plate 222 to the center axis is r1, the distance from the lower end of the elastic plate 222 to the center axis is r2, R is greater than r1 and less than r2. When the fixing plate 1 is fixed, the metal ring 23 can be easily sleeved on the elastic plate 222 from top to bottom. Because the distance r2 from the lower end of the elastic plate 222 to the center axis is greater than the radius R of the metal ring 23, the metal ring 23 will be stuck on the elastic plate 222 and press the elastic plate 222 when moving downward. The elastic plate 222 pressed in this way moves in a shrinking manner to tighten the clamping structure and firmly buckle the positioning groove.

[0045] In the embodiment, as shown in Figure 3 The base 221 is provided with a center hole 2211, which is used to connect external structures.

[0046] In the embodiment, as shown in Figure 3 The base 221 is further provided with a nut, and the screw hole of the nut is consistent with and communicates with the center hole 2211. Through the communication between the nut and the center hole 2211, the screw rod in the external structure can be connected with the fixing assembly 2, thereby fixing the plate 1.

[0047] The positioning claw is provided on one end of the elastic plate away from the base, and the distance from the end of the elastic plate away from the base to the center axis is greater than the distance from the end close to the base to the center axis. The distance from the end of the positioning claw away from the base to the center axis is greater than the distance from the end close to the base to the center axis.

[0048] Embodiment 2

[0049] The difference between embodiment 2 and embodiment 1 is that, as shown in Figure 4 The positioning groove 101 is circular in the cross section of the plate 1, and the diameter of the circular shape on each cross section from the surface to the inside (i.e. from top to bottom) gradually increases, that is, the positioning groove 101 is set in an explosive manner away from the center axis. The fixing assembly 2 comprises at least two positioning claws 201, which are set in a similar manner to the positioning groove 101, that is, in an explosive manner. The at least two positioning claws 201 can be, for example, 2, 3, 4, 5, 6, 7, 8, 9 or 10. Among them, 3, 4, 5, 6, 7 or 8 is the best. When the at least two positioning claws 201 are embedded in the positioning groove 101, the positioning groove 101 is divided into equal length arcs. Through the setting of the positioning groove 101 in an expanding manner from top to bottom (similar to an expanding screw) and the equal interval setting of the positioning claw 201, the positioning claw 201 can be effectively prevented from directly exiting the positioning groove 101, and the horizontal force acting on the fixing assembly 2 can be balanced, thereby strengthening the fixing and connecting effect.

[0050] Embodiment 3

[0051] Example 3 differs from Example 1 in that the positioning groove presents several circular arcs on the cross section of the plate, and the several circular arcs are distributed equidistantly along the circular periphery, and the diameter of the circle corresponding to the several circular arcs gradually decreases from the outside to the inside. That is, the positioning groove is not a complete annular groove, but a positioning groove with several circular-arc grooves combined to form an incomplete circle. The fixing assembly also includes positioning claws corresponding to the number of circular arcs, which are embedded in the positioning groove to tighten the positioning groove when the positioning claws are embedded in the positioning groove, having the same effect as Example 1.

[0052] The above-described examples only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as limiting the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
