[0027] The technical solution of the present invention has the following advantages:

[0028] 1. An installation structure provided by the present invention, the installation structure is adapted to install a decorative surface on a corresponding surface to be installed, the installation structure includes: a keel and a connecting member, one of the keel and the connecting member is configured on the decorative surface, and the other is configured on the surface to be installed; wherein, the keel includes a keel body and an extrusion part, the extrusion part is adapted to form an insertion channel, the keel body has a receiving cavity, the insertion channel communicates with the receiving cavity, the connecting member includes an extrusion fitting, the extrusion fitting has an extrusion fitting part, under the action of an external force, one end of the extrusion fitting part is adapted to pass through the insertion channel to extend into the receiving cavity; the extrusion part has an extrusion state tending to approach the extrusion fitting part, in the extrusion state, the extrusion part is adapted to apply a biasing force to the extrusion fitting part to keep the extrusion part and the extrusion fitting part in abutting pressure, so that the keel is connected to the extrusion fitting.

[0029] In the installation structure of this structure, the decorative surface is installed on the corresponding surface to be installed by using this installation structure. The surface to be installed is at least one of the top surface, the ground surface and the wall surface. When the decorative surface is installed on the corresponding surface, the installation structure includes a keel and a connecting member. One of the keel and the connecting member is arranged on the decorative surface, and the other is arranged on the surface to be installed. The keel includes a keel body and an extrusion part. Among them, the extrusion part is suitable for forming an insertion channel. The keel body has a receiving cavity, and the insertion channel is communicated with the receiving cavity. The connecting member includes an extrusion fitting part, and an extrusion fitting part is arranged on the extrusion fitting part. Under the action of an external force, one end of the extrusion fitting part is suitable for passing through the insertion channel to extend into the receiving cavity, so as to complete the connection between the extrusion fitting part and the keel. After the extrusion fitting part is inserted into the receiving cavity, the extrusion part on the keel body has an extrusion state of tending to approach the extrusion fitting part. In this extrusion state, the extrusion part can apply a biasing force to the extrusion fitting part to keep the extrusion part and the extrusion fitting part in pressing contact, so as to keep the keel and the extrusion fitting part connected, thus achieving the effect of installing the decorative surface on the surface to be installed. Moreover, this installation method is simple. By inserting the extrusion fitting part of the extrusion fitting into the insertion channel of the keel body, the effect of installing the decorative surface on the surface to be installed can be achieved. This installation structure can be commonly used for installation between the top surface, the ground surface, the wall surface and the decorative surface, and is suitable for the current installation system between the top, the ground, the wall and the decorative surface, which is convenient for the production and installation of the decorative surface. Moreover, during the production and installation process, the complexity of production and installation is reduced. On the basis of not needing to consider the installation sequence between the top surface, the ground surface, the wall surface and the decorative surface, the operation difficulty of the operator is effectively reduced, and subsequent maintenance of the decorative surface is also convenient, overcoming the defects in the existing prefabricated installation structure. For example, when each manufacturer of the top, the ground and the wall designs and prefabricates the installation structure, the installation structure applied to the top cannot be used in a compatible manner with the installation applied to the ground or the wall, which increases the complexity of production and installation. For example, there are problems such as how to distinguish the front and back order in cross-operation, and whether there is mutual interference and increased maintenance difficulty during later maintenance.

[0030] 2. In the installation structure provided by the present invention, the keel includes two oppositely arranged bending arms, and the two bending arms are suitable for bending towards the inside of the receiving cavity, and the two bending arms are suitable for forming the extrusion part, so as to be in pressing contact with the extrusion fitting part after the extrusion fitting part passes through the extrusion part and inserts into the receiving cavity.

[0031] In the installation structure of this structure, the keel includes two bending arms arranged opposite to each other, and the two bending arms are bent toward the inside of the accommodating cavity to form the extrusion portion. When the extrusion fitting portion of the extrusion fitting piece is inserted into the accommodating cavity, the extrusion portion can be pressed against the extrusion fitting portion, so that the extrusion portion of the keel body can apply a biasing force to the extrusion fitting portion, so that the keel body and the extrusion fitting piece are stably connected, further improving the installation stability between the decorative surface and the surface to be installed, and the structure of the keel is simple, which can further reduce the difficulty of production.

[0032] 3. In the installation structure provided by the present invention, the two bending arms are suitable for being arranged opposite to each other, and there is a gap between the two bending arms or the two bending arms are arranged in abutment with each other, and the two bending arms form the insertion channel.

[0033] In the installation structure of this structure, an insertion channel can be formed by arranging two bending arms opposite to each other with an interval or abutment between them. When the extrusion fitting part of the extrusion fitting passes through the insertion channel and extends into the accommodating cavity, the extrusion fitting part of the extrusion fitting will stretch the two bending arms apart, thereby entering the accommodating cavity, and the bending arm will have a tendency to return to its original state, thereby achieving the effect of applying bias force to the extrusion fitting part.

[0034] 4. In the installation structure provided by the present invention, when the surface to be installed is the ground, the decorative surface is the ground decorative surface, the keel is arranged on the ground decorative surface, and the connecting member also includes a support member and a bearing seat, and the support member and the bearing seat are both arranged on the ground, wherein the support member is fixed on the ground, and the bearing seat is suitable for being installed on the support member; at least one second extrusion fitting member is arranged on the bearing seat, and the second extrusion fitting member is suitable for being inserted into the insertion channel of the keel to press against the extrusion portion.

[0035] In the installation structure of this structure, the surface to be installed is set as the ground, and correspondingly, the decorative surface is set as the ground decorative surface, and the keel is arranged on the ground decorative surface. At the same time, the connection structure also includes a support member and a bearing seat.

At the same time, a second extrusion fitting member is arranged on the bearing seat, and the second extrusion fitting member can be inserted into the plug-in channel of the keel to press against the extrusion part, so as to complete the effect that the ground decorative surface is installed on the ground through the keel and the support member, the bearing seat and the second extrusion fitting member. At this time, the keel plays a supporting role, and is fixed and connected to the bearing seat by the extrusion fitting member, so that the accessories can be reused, especially suitable for the use scenario of elevated ground decorative surface, without the need to use a large number of self-tapping screws for fixing, which effectively improves the reuse rate and effectively reduces the production cost.

[0036] 5. In the installation structure provided by the present invention, the connecting member further includes a limiting member. When the keels are arranged in a cross shape on the bearing seat, the limiting member is adapted to cover and abut against the outer wall surfaces of all the keels.

[0037] In the installation structure of this structure, when the surface to be installed is the ground, the connecting member further includes a limiting member. When a keel structure arranged in a cross shape is provided on the bearing member, the limiting member can cover and abut against the outer wall surfaces of all the keels, so as to exert a blocking force on the keels to prevent relative displacement between the keels, further improving the structural stability.

[0081] Embodiment 1

[0082] This embodiment describes an installation structure. The installation structure is suitable for installing a decorative surface on a corresponding surface to be installed. The installation structure includes a keel 100 and a connecting member 200. One of the keel 100 and the connecting member 200 is arranged on the decorative surface, and the other is arranged on the surface to be installed. The decorative surface is installed on the surface to be installed by using the keel 100 and the connecting member 200.

[0083] Specifically, refer to Figures 1 - 3, in order to achieve the effect of installing the decorative surface on the surface to be installed, the above-mentioned keel 100 includes a keel body 101 and an extrusion part 102. The extrusion part 102 can form an insertion channel 103. The keel body 101 has a receiving cavity 104. The insertion channel 103 is communicated with the receiving cavity 104. The above-mentioned connecting member 200 includes an extrusion fitting 201. The extrusion fitting 201 has an extrusion fitting part 2011. Under the action of an external force, one end of the extrusion fitting part 2011 is adapted to pass through the insertion channel 103 formed by the extrusion part 102 and extend into the receiving cavity 104. After one end of the extrusion fitting part 2011 passes through the insertion channel 103 and extends into the receiving cavity 104, the extrusion part 102 has an extrusion state of approaching the extrusion fitting part 2011. In this extrusion state, the extrusion part 102 is adapted to apply a biasing force to the extrusion fitting part 2011, so that the extrusion part 102 and the extrusion fitting part 2011 are kept in pressing contact, so as to connect the keel and the extrusion fitting 201.

[0084] In this embodiment, referring to Figures 1 - 24Using this installation structure, the decorative surface is installed on the corresponding surface to be installed. The surface to be installed is at least one of the top surface, the ground surface, and the wall surface. The corresponding decorative surface can be the wall decorative surface 600, the ground decorative surface 800, and the top surface decorative surface 700. When installing the decorative surface on the corresponding surface, the installation structure includes a keel and a connecting member 200. One of the keel and the connecting member 200 is configured on the decorative surface, and the other is configured on the surface to be installed. The keel includes a keel body 101 and an extrusion part 102. Among them, the extrusion part 102 is adapted to form a plugging channel 103. The keel body 101 has a receiving cavity 104. The plugging channel 103 is communicated with the receiving cavity 104. The connecting member 200 includes an extrusion fitting 201. An extrusion fitting part 2011 is arranged on the extrusion fitting 201. Under the action of an external force, one end of the extrusion fitting part 2011 is adapted to pass through the plugging channel 103 and extend into the receiving cavity 104, thereby completing the connection between the extrusion fitting 201 and the keel. And after the extrusion fitting part 2011 is inserted into the receiving cavity 104, the extrusion part 102 on the keel body 101 has an extrusion state of tending to approach the extrusion fitting part 2011. In this extrusion state, the extrusion part 102 can apply a biasing force to the extrusion fitting part 2011 to keep the extrusion part 102 and the extrusion fitting part 2011 in abutment pressure, so as to keep the keel and the extrusion fitting 201 connected, thereby completing the effect of installing the decorative surface on the surface to be installed. And this installation method is simple. By inserting the extrusion fitting part 2011 of the extrusion fitting 201 into the plugging channel 103 of the keel body 101, the effect of installing the decorative surface on the surface to be installed can be achieved. This installation structure can be commonly installed between the top surface, the ground surface, the wall surface and the decorative surface, and is applicable to the current installation system between the top, the ground, the wall and the decorative surface, which is convenient for the production and installation of the decorative surface. And during the production and installation process, the complexity of production and installation is reduced. On the basis of not needing to consider the installation sequence between the top surface, the ground surface, the wall surface and the decorative surface, the operation difficulty of the operator is effectively reduced, and the subsequent maintenance of the decorative surface is also convenient.

[0085] It should be noted that the common installation between the top surface, the ground surface, the wall surface and the decorative surface means that the produced keel structure is common. Then, by cooperating with the extrusion fitting 201 with the corresponding structure, only by inserting the end of the extrusion fitting 201 into the receiving cavity 104 of the keel can the installation be realized. In actual production, for the installation between the top surface, the ground surface, the wall surface and the decorative surface, the keel plays a main role in support and installation. Therefore, in this embodiment, the keel is set as a common structure, which is beneficial to the common installation of the top, ground and wall system.

[0086] Specifically, see Figures 1 - 4In order to further improve the installation stability between the decorative surface and the surface to be installed, the above-mentioned keel includes two relatively arranged bending arms 105, and the two bending arms 105 are suitable for bending into the accommodating cavity 104. The two bending arms 105 are suitable for constituting the above-mentioned extrusion portion 102, so that after the extrusion fitting portion 2011 passes through the extrusion portion 102 to be inserted into the accommodating cavity 104, the two bending arms 105 are pressed against the extrusion fitting portion 2011, so that the extrusion portion 102 of the keel body 101 can apply a biasing force to the extrusion fitting portion 2011, so that the keel body 101 and the extrusion fitting piece 201 are stably connected, further improving the installation stability between the decorative surface and the surface to be installed, and the structure of the keel is simple, which can further reduce the difficulty of production, wherein the above-mentioned extrusion fitting portion 2011 and the extrusion portion 102 are continuously pressed against each other, and when the keel and the connecting member 200 need to be disassembled, the extrusion fitting portion 2011 of the extrusion piece only needs to be withdrawn from the accommodating cavity 104 along the insertion channel 103 to complete the disassembly between the two.

[0087] See also Figure 2 The two bending arms 105 on the above-mentioned keel body 101 are suitable for being arranged relative to each other, and there is a gap between the two bending arms 105 or the two are arranged in abutment with each other. The two bending arms 105 form the plug-in channel 103. By arranging the two bending arms 105 relative to each other and arranging them with a gap or abutment with each other, the plug-in channel 103 can be formed. When the extrusion fitting part 2011 of the extrusion fitting part 201 passes through the plug-in channel 103 and extends into the accommodating cavity 104, the extrusion fitting part 2011 of the extrusion fitting part 201 will stretch the two bending arms 105 apart, thereby entering the accommodating cavity 104, and the bending arm 105 will have a tendency to return to its original state, thereby achieving the effect of applying bias force to the extrusion fitting part 2011.

[0088] Of course, in actual use, the interval may be set slightly larger. In this case, the extrusion fitting portion 2011 of the extrusion fitting piece 201 can be directly inserted into the accommodating cavity 104 more easily, in a loose fitting manner.

[0089] Specifically, see Figure 2 Any of the above-mentioned bending arms 105 includes a first bending edge 1051 and a second bending edge 1052 that are symmetrically arranged. In actual use, at least the first bending edge 1051 is arranged in the accommodating cavity 104 to form a plug-in channel 103. At the same time, the first bending edge 1051 and the second bending edge 1052 have a smooth transition, and a transition section 1053 is provided between the first bending edge 1051 and the second bending edge 1052. The two transition sections 1053 are spaced or abutted against each other, so that there is a spacing or abutment setting between the two bending arms 105, and the pressure between the extrusion fitting portion 2011 and the bending arm 105 is the pressure between the extrusion fitting portion 2011 and the transition section 1053.

[0090] See also Figure 1 The first bending edge 1051 is arranged in the accommodating cavity 104, and the second bending edge 1052 is located at the end of the keel body 101. The two bending edges are arranged at intervals to form the plug-in channel 103. When the extrusion fitting part 2011 of the extrusion fitting part 201 is transported along the plug-in channel 103, the extrusion fitting part 2011 is inserted into the plug-in channel 103. At the same time, the spacing of the plug-in channel 103 away from the accommodating cavity 104 needs to be slightly smaller than the width of the extrusion fitting part 2011. degree, so that the extrusion fitting part 2011 of the extrusion fitting part 201 can open the first bending edges 1051 of the two bending arms 105, so as to enter the accommodating cavity 104. It should be noted that the first bending edge 1051 of the bending arm 105 of this structure is arranged in the accommodating cavity 104, and it is arranged at an angle with the axis of the keel body 101, and the second bending edge 1052 is located at the end of the keel body 101, and it is arranged perpendicular to the axis of the keel body 101.

[0091] As another embodiment of the bending arm 105, see Figure 3 The first bending edge 1051 and the second bending edge 1052 can be both arranged in the accommodating cavity 104, and the two are arranged at an interval. At this time, the first bending edge 1051 and the second bending edge 1052 are both arranged at an angle to the axis of the keel body 101, and the extrusion fitting part 2011 is pressed against the transition section 1053.

[0092] As another embodiment of the bending arm 105, see Figure 4 The first bending edge 1051 and the second bending edge 1052 can be both arranged in the accommodating cavity 104, and the two transition sections 1053 in the structure are spaced apart. At this time, the first bending edge 1051 and the second bending edge 1052 are both arranged at an angle to the axis of the keel body 101. At this time, the extrusion fitting part 2011 is pressed against the transition section 1053, and the interval value between the two is smaller than the interval value in the figure.

[0093] Of course, the transition sections 1053 on the two bending arms 105 may also be directly abutted against each other, and the two transition sections 1053 may be spread apart by using the extrusion fitting portion 2011, thereby further spreading apart the two bending arms 105.

[0094] In actual use, in order to further improve the smoothness of the extrusion fitting part 2011 being transported along the insertion channel 103 , the interval between the two second bent edges 1052 gradually increases in the direction in which the extrusion fitting part 201 is inserted into the accommodating cavity 104 along the insertion channel 103 .

The first extrusion fitting 203 is adapted to be inserted into the insertion channel 103 of the wall keel 300 to press against the extrusion portion 102, so as to complete the installation of the wall decorative surface 600 on the wall surface.

[0096] See Figure 5 , the wall decorative surface 600 in this embodiment is a wallboard structure. One connecting member 200 corresponds to two wallboard structures. A first extrusion fitting 203 is arranged on the opposite end parts of two adjacent wallboard structures. A part of the keel body 101 of the wall keel 300 is arranged in the first fixing member 202. The first fixing member 202 includes a fixing body and fixing arms arranged on both sides of the fixing body. The two fixing arms are installed on the wall surface through first fasteners.

The extrusion fitting part of the second extrusion fitting 206 can be inserted into the insertion channel 103 of the keel to be in pressing contact with the extrusion part 102, completing the effect of installing the floor decorative surface 800 on the ground 2 through the keel 100, the support member 204, the bearing seat 205, and the second extrusion fitting 206. At this time, the role of the floor keel 500 is a supporting role, and it is fixed and connected with the bearing seat 205 through the extrusion fitting 201, which can realize the reuse of accessories, especially applicable to the use scenario of the elevated floor decorative surface 800, without using a large number of self-tapping screws for fixation, effectively improving the reuse rate and effectively reducing the production cost.

[0101] In this embodiment, refer to Figures 10 - 12, it is possible to mount three floor keels 500 on at least one carrier 205. The three floor keels 500 are arranged in a cross on the carrier 205. Specifically, the second extrusion fitting 206 can be set to a T-shaped structure. The extrusion fitting portion 2011 described above is the horizontal portion of the second extrusion fitting 206 with a T-shaped structure. The extrusion fitting portion 2011 on the horizontal portion of the extrusion fitting 201 is adapted to be inserted into the receiving cavity 104, and the extrusion fitting portion 2011 is set to a planar structure.

[0102] Of course, it is also possible to mount four floor keels 500. The four floor keels 500 are arranged in a cross on the carrier 205. The installation method between each floor keel 500 and the carrier 205 is the same, and will not be elaborated here.

[0103] In this embodiment, the distance between the two bending arms 105 can also be set to be relatively larger. At this time, after the extrusion fitting portion 2011 of the second extrusion fitting 206 extends into the receiving cavity 104, it rotates 90 degrees in the receiving cavity 104 and then touches the bending arm 105 downward, and then the connection between the second extrusion fitting 206 and the floor keel 500 is completed by using a nut.

[0104] Specifically, referring to Figure 11 and Figure 12 , it is possible to mount the first floor keel 501 on two opposite installation fitting holes 2051 through the second extrusion fitting 206, and connect the second floor keel 502 and the third floor keel 503 to the other two opposite installation fitting holes 2051 respectively through the second extrusion fitting 206. The second floor keel 502 and the third floor keel 503 are respectively arranged on both sides of the first floor keel 501 to be arranged in a cross on the carrier 205.

[0105] When there are three floor keels 500 arranged in a cross on the carrier 205, referring to Figure 8 , Figure 11 and Figure 12 , the connecting member 200 in this embodiment further includes a limiting member 207.

Referring to Figure 8, the limiting member 207 includes a limiting body 2071 and a limiting portion 2072. A limiting portion 2072 is provided at each corner of the limiting body 2071. When the limiting member 207 covers the outer wall surface of all the floor keels 500 and abuts against the outer wall surface of the floor keel 500, the limiting portion 2072 is bent towards the floor keel 500 relative to the limiting body 2071 to prevent the limiting body 2071 from moving relative to the floor keel 500, thereby avoiding relative displacement between the three floor keels 500 arranged in a cross shape on the bearing seat 205 and further improving the structural stability.

[0106] In this embodiment, each of the above-mentioned limiting portions 2072 is a hem formed on the limiting body 2071, and the hem is bent towards the floor keel. The hem is perpendicularly arranged with respect to the limiting body 2071. In this embodiment, the bearing seat 205 is arranged on the ground through a support member 204.
