Description

Technical Field

[0001] This utility model relates to the field of building decoration materials technology, and in particular to a matching clip for installing metal skirting boards. Background Technology

[0002] Metal skirting boards are widely favored in modern interior design due to their strong lines, durability, and ease of cleaning. To maintain the integrity and aesthetics of the metal skirting board surface and avoid exposed nail holes, the mainstream installation method currently uses matching mounting clips. During installation, these clips are first fixed to the wall substrate at specific intervals. Then, the grooves on the back of the metal skirting board are aligned with the clips, and the board is installed and secured using a snap-fit ​​method.

[0003] This installation method is theoretically convenient and efficient, but its actual application effect is highly dependent on one prerequisite: the flatness of the wall surface. In real-world construction environments, the wall base, especially walls treated with putty or paint, will almost inevitably have localized unevenness, undulations, or vertical deviations.

[0004] Most existing installation clips are simple, rigid sheets or blocks lacking inherent adjustability. When installers forcibly fix these rigid clips to uneven walls with screws, the clips fail to fit snugly, creating gaps or causing slight twisting and tilting due to uneven stress. This installation defect leads to a series of serious consequences: firstly, the clips are not securely fixed, resulting in uneven stress; secondly, and most importantly, when metal baseboards are fastened to clips that are not on the same plane, noticeable height misalignment occurs at the baseboard joints, or the baseboard lines become wavy, severely damaging the overall aesthetic appeal of the decoration. Currently, installers can only rely on manual leveling methods, such as adding shims behind the clips, which is time-consuming, labor-intensive, and difficult to control in terms of precision.

[0005] Therefore, this utility model proposes a matching clip for installing metal skirting boards to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a matching clip for installing metal skirting boards, aiming to improve the problems of existing matching clips for installing metal skirting boards, which, due to their rigid structure and lack of adjustment capabilities, cannot fit tightly against uneven walls, resulting in misalignment of skirting board joints or deformation of lines.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a matching fastener for installing a metal kickboard, comprising: A base plate, wherein a T-shaped groove is formed along its length, and positioning holes are formed along the length of the T-shaped groove; The upper connector is fixedly connected to one end of the base plate; The lower connector has a T-shaped block fixedly connected to its back, and the T-shaped block is slidably fitted into the T-shaped groove of the base plate; And a pin locking structure provided on the lower connector and a threaded post passing through the base plate; The pin locking structure includes a fixed plate, a sliding plate, a pull ring, a positioning pin, and a spring. Furthermore, the fixed plate is fixed to the lower connector, the pull ring is connected to the outside of the sliding plate, the positioning post is fixedly connected to the sliding plate, the spring is sleeved on the outside of the positioning post and its two ends abut against the sliding plate and the fixed plate respectively, and the positioning post can be selectively inserted into any of the positioning holes; The threaded post includes a handle and a bolt. The handle is located on one side of the front of the base plate. The bolt is threadedly connected to the handle. The axis of the bolt is perpendicular to the surface of the base plate and its end can extend out of the back of the base plate. Preferably, the spring is a compression spring, which, in its natural state, pushes the sliding disk to keep the positioning post in the position of being inserted into the positioning hole; Preferably, the pull ring is used to drive the sliding disk to move in a direction away from the fixed disk, so as to compress the spring and cause the positioning pin to disengage from the positioning hole; Preferably, the rotational motion of the hand-held tray is converted into the linear motion of the bolt through a threaded transmission; Preferably, the locking structure is integrally installed on the side of the lower connector; Preferably, both the upper connector and the lower connector are formed into a hook shape for engaging the metal kick plate; Preferably, the cross-sectional shape of the T-block matches the cross-sectional shape of the T-slot; Preferably, the base plate is further provided with mounting through holes for fasteners to pass through in order to fix the base plate to the wall.

[0008] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that the clips cannot fit the wall surface due to unevenness and the installation flatness is poor. It achieves the effect of accurately adjusting the installation angle and ensuring that the base plate fits tightly with the wall surface by setting a threaded column fine adjustment mechanism consisting of a handle and bolts on the base plate.

[0009] 2. This utility model solves the problem of fixed joint spacing of existing card parts and inability to adapt to different specifications of kickboards by setting a sliding fit structure of T-slot and T-block, combined with a pin locking structure composed of pull ring, positioning post and spring. It achieves the effect of quick adjustment of joint spacing and firm and reliable positioning, and enhances the versatility of the product.

[0010] 3. This utility model solves the problem that traditional installation methods may require drilling and damage to the surface of the skirting board by setting the upper and lower connectors to a hook shape, so that the metal skirting board can be installed in a snap-fit ​​manner. It achieves the effect of keeping the skirting board surface intact and beautiful, while also being convenient and efficient to install. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Reference Figures 1-4The present invention provides an embodiment of a matching fastener for installing a metal kickboard, comprising a base plate 1 as an installation base, an upper connector 101 fixedly connected to one end of the base plate 1, and a lower connector 102 that can slide along the base plate 1. The base plate 1 has a T-shaped groove 301 along its length direction, and a plurality of positioning holes 302 distributed along the length direction of the T-shaped groove 301 are also provided on the base plate 1. A T-shaped block 3 is fixedly connected to the back of the lower connector 102. The cross-sectional shape of the T-shaped block 3 matches the cross-sectional shape of the T-shaped groove 301, thereby realizing the sliding connection of the lower connector 102 on the base plate 1. To achieve precise positioning and locking of the lower connector 102 after sliding, a complete pin locking structure is provided on the lower connector 102. This pin locking structure is integrally installed on the side of the lower connector 102 and includes a fixed plate 304, a sliding plate 303, a pull ring 305, a positioning post 306, and a spring 307. The fixed plate 304 is fixed to the lower connector 102, the pull ring 305 is externally connected to the sliding plate 303, the positioning post 306 is fixedly connected to the sliding plate 303, and the spring 307 is a compression spring. The spring 307 is sleeved on the outside of the positioning post 306, with both ends abutting against the sliding plate 303 and the fixed plate 304 respectively. In its natural state, the spring 307 pushes the sliding plate 303 to achieve positioning. The column 306 remains inserted into the selected positioning hole 302, thereby locking the lower connector 102. To solve the installation problem caused by uneven wall surface, a threaded column 2 is provided on the base plate 1. The threaded column 2 includes a handle 202 and a bolt 201. The handle 202 is located on one side of the front of the base plate 1. The bolt 201 and the handle 202 are connected by a threaded drive. The axis of the bolt 201 is perpendicular to the surface of the base plate 1, and the end of the bolt 201 can extend out of the back of the base plate 1 to be used for fine adjustment against the wall surface. In addition, both the upper connector 101 and the lower connector 102 are formed into a hook shape for fastening metal skirting boards. The base plate 1 is also provided with a mounting through hole for fasteners to pass through to fix the base plate 1 to the wall surface. It also includes a pin locking structure located on the side of the lower connector 102, and this pin locking structure forms a specific sliding locking fit and connection relationship with the aforementioned base plate 1 and lower connector 102. The pin locking structure mainly consists of a fixed plate 304, a sliding plate 303, a pull ring 305, a positioning post 306, and a spring 307. The fixed plate 304 is fixedly connected to the side wall of the lower connector 102 and serves as a fixed support for the spring 307. The sliding plate 303 is located on one side of the fixed plate 304 and is connected to the pull ring 307. The lower connector 102 is externally connected to the positioning post 306. One end of the positioning post 306 is fixedly connected to the sliding plate 303, and the other end of the positioning post 306 passes through the fixed plate 304 and extends to the inner side of the lower connector 102. The spring 307 is sleeved on the outside of the positioning post 306 and its two ends abut against the sliding plate 303 and the fixed plate 304 respectively. In the assembled state, the lower connector 102 slides in the T-shaped groove 301 opened along its length direction on the base plate 1 through the T-shaped block 3 fixedly connected to its back. The base plate 1 also has multiple grooves along the T-shaped groove 301. The positioning holes 302 are distributed along the length direction. In the natural state where the pull ring 305 is not pulled by external force, the spring 307 uses its own elastic restoring force to push the sliding plate 303 towards the base plate 1, thereby causing the positioning pin 306 fixed on the sliding plate 303 to insert into the corresponding positioning hole 302 on the base plate 1. At this time, the cooperation between the positioning pin 306 and the positioning hole 302 restricts the relative movement of the lower connector 102 relative to the base plate 1. When it is necessary to adjust the position of the lower connector 102, the pull ring 305 is pulled. The sliding plate 303 moves away from the fixed plate 304. During this movement, the spring 307 is compressed and the positioning pin 306 is completely disengaged from the positioning hole 302, releasing the locking state between the lower connector 102 and the base plate 1. This allows the lower connector 102 to slide freely along the T-slot 301 to a new predetermined position. After the pull ring 305 is released, the positioning pin 306 automatically resets under the action of the spring 307 and inserts into the new positioning hole 302, thereby realizing the rapid adjustment and reliable locking of the position of the lower connector 102. As a preferred embodiment, in order to make precise fine-tuning of the installation angle of the base plate 1 for uneven wall surfaces, the threaded post 2 passing through the base plate 1 specifically includes a handle 202 set on one side of the front of the base plate 1 and a bolt 201 connected to the handle 202 through internal threads. The axis of the bolt 201 is set perpendicular to the surface of the base plate 1. The handle 202 is configured to drive the bolt 201 to move linearly along its axis through rotational motion, so that the end of the bolt 201 can extend out of the back of the base plate 1 and abut against the wall surface, thereby forming an adjustable support distance between the base plate 1 and the wall surface. As another preferred embodiment, in order to improve the convenience and firmness of the connection between the metal kick plate and the clip, the upper connector 101 fixedly connected to one end of the base plate 1 and the lower connector 102 slidably connected to the base plate 1 are both formed into a barb shape for engaging the back slot of the metal kick plate. The opening direction of the barb shape is towards the opposite side or adapted to the specific slot form of the kick plate, so as to ensure that a firm mechanical engagement can be formed with the metal kick plate after the lower connector 102 is locked in position. In addition, to ensure the guiding accuracy of the lower connector 102 during movement and to prevent it from falling off, the cross-sectional shape of the T-shaped block 3 fixed to the back of the lower connector 102 is perfectly matched with the cross-sectional shape of the T-shaped groove 301 opened on the base plate 1. The shape fit formed by the T-shaped block 3 embedded in the T-shaped groove 301 restricts the displacement of the lower connector 102 in the direction perpendicular to the base plate 1, and only allows the lower connector 102 to slide back and forth in a straight line along the length direction of the T-shaped groove 301. At the same time, in order to facilitate the firm installation of the base plate 1 on the wall, several through holes penetrating the thickness direction of the base plate 1 are also provided on the plate body. These through holes are used for fasteners such as expansion bolts to pass through and be anchored in the wall.

[0015] Working principle: When in use, the base plate 1 is first fixed to the wall through the mounting holes. If the wall is not flat enough and the base plate 1 cannot fit completely, the operator manually rotates the handle 202. The rotation of the handle 202 is converted into the linear motion of the bolt 201 through the thread transmission, so that the bolt 201 extends along the axis to the back of the base plate 1 and abuts against the wall. Continue to rotate to generate a pushing force to push the corresponding position of the base plate 1 outward until the base plate 1 is adjusted to the ideal installation angle. When it is necessary to adjust the joint spacing to fit different sizes of kickboards, pull the pull ring 305 outward. The pull ring 305 drives the sliding plate 303 to move away from the fixed plate 304 and compress the spring 307. The positioning pin 306 fixed on the sliding plate 303 moves accordingly and completely disengages from the current positioning hole 302. At this time, the lower joint 102 is unlocked. The lower joint 102 slides along the T-slot 301 on the base plate 1 by relying on the T-block 3 on the back. When it moves to the predetermined position and aligns with the new positioning hole 302, the pull ring 305 is released. The spring 307 releases its elastic potential energy to push the sliding plate 303 to reset, driving the positioning pin 306 to insert into the new positioning hole 302 to complete the pin-type locking. Finally, the metal kickboard is fastened and installed by the cooperation of the hook structure of the upper joint 101 and the lower joint 102.
