Description

Technical Field

[0001] This utility model relates to the field of hardware auxiliary tools technology, specifically to a modular combined hardware connector. Background Technology

[0002] Hardware connectors are metal or plastic products used to firmly and stably join two or more components (such as wood, board, metal, plastic, etc.). As the core basic element for achieving reliable connection between structural components, hardware connectors are mainly used in many fields such as modern industrial manufacturing, building decoration, furniture assembly and exhibition equipment construction.

[0003] A search revealed Chinese patent CN222185320U, which discloses a hardware connector comprising: a main connector having a main fixing block for fixing, with a plug-in post connected to the center of the main fixing block; and a secondary connector including a secondary fixing plate for fixing to the ground, with a plug-in cylinder connected to the center of the secondary fixing plate to cooperate with the plug-in post, and a fixing structure for fixing the plug-in post connected to the side of the plug-in cylinder. This utility model, by fixing the secondary fixing plate to the ground, can position the fixed object connected to the main fixing block, and the connection and disassembly are quick and convenient to use.

[0004] Existing hardware connectors mostly use a combination of plug-in posts and plug-in sleeves for connection. Although this allows for quick assembly and disassembly, their functional design is often relatively simple. The fixed specifications and non-adjustable extension length of traditional connectors mean they can only be used for frame structures of specific models or sizes. They are difficult to adapt to different connection requirements for different sizes of stall racks. The flexibility and versatility of traditional connectors are obviously insufficient, and in practical applications, they are prone to problems such as unstable support or limited installation. Based on this, a modular combination hardware connector is proposed to solve the above problems. Utility Model Content

[0005] Based on the above description, this utility model provides a modular combined hardware connector to solve the problem that traditional connectors are significantly lacking in flexibility and versatility in different usage scenarios.

[0006] The technical solution of this utility model to solve the above technical problems is as follows: A modular combined hardware connector includes a supporting base plate, a countersunk hole opened on the supporting base plate, and a load-bearing cylinder fixed in the countersunk hole. The load-bearing cylinder is a hollow cylinder with its middle part recessed downward to form a concave arc surface. The upper side of the load-bearing cylinder is provided with a support adjustment mechanism to adapt to different usage needs, and an installation mechanism for connection is provided between the load-bearing cylinder and the side opposite to the support adjustment mechanism. The support adjustment mechanism includes a fixed plate disposed on the upper side of the load-bearing cylinder and two extension plates slidably connected to the fixed plate. Sliding grooves for the extension plates to slide are provided on both the left and right sides of the fixed plate. The extension plate is provided with positioning elements on both the front and rear sides for positioning the extension plate in the horizontal direction.

[0007] The above technical solution, with its modular design, not only facilitates production and assembly but also allows for the selection and installation of different styles of fixing plates according to actual needs, thus improving assembly efficiency. By having two extension plates slide within the sliding grooves of the fixing plates, the horizontal support area is expanded, enabling the fixing plates to adapt to different sizes of stalls, thereby ensuring the stability of the stall support and improving versatility during use.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the positioning component includes springs fixed on the front and rear sides of the extension plate, with positioning posts fixed on the opposite sides of the springs on both sides, and multiple positioning holes are provided at both ends of the outer surface of the fixing plate.

[0010] The above technical solution allows for adjustment of the length of the positioning pin extending into the positioning hole in the horizontal direction, thereby adjusting the extension length of the extension plate.

[0011] Furthermore, the outer diameter of the positioning post is adapted to the inner diameter of the positioning hole, and the positioning posts on the front and rear sides are located on the same straight line.

[0012] The above technical solution ensures that the front and rear ends of the extension plate move synchronously during the extension or retraction process, preventing misalignment that could cause jamming.

[0013] Furthermore, the installation mechanism includes a first ear plate fixed to the top of the outer surface of the load-bearing cylinder, and two threaded holes are opened at both the left and right ends of the upper surface of the first ear plate. The lower surface of the fixed plate is fixed with a second ear plate. Two hexagonal holes are opened at both ends of the upper surface of the fixed plate and the second ear plate. A limit rod is fixed on the lower surface of the second ear plate. The limit rod is located inside the load-bearing cylinder and its lower end has an isosceles trapezoidal cross-section.

[0014] Through the above technical solution, by connecting the first ear plate and the second ear plate, the upper fixing plate, extension plate, load-bearing cylinder, and support base plate are all separated into independent modules, which facilitates separate processing. The design of the bottom of the limiting rod allows it to be naturally guided into the inner cavity of the load-bearing cylinder during installation.

[0015] Furthermore, the upper surface of the fixing plate is provided with a mounting groove, and the inner cavity of the mounting groove is threadedly connected to a screw rod. The lower surface of the screw rod passes through the mounting groove and extends into the limiting rod. The multiple hexagonal holes and multiple threaded holes, which correspond one-to-one, are threadedly connected to the same No. 2 screw.

[0016] With the above technical solution, the threaded hole on the first ear plate is aligned with the hexagonal hole on the fixing plate and the second ear plate, allowing the second screw to be inserted from above and screwed in, forming a two-way tightening force.

[0017] Furthermore, mounting holes are symmetrically provided at both ends of the upper surface of the support base plate, and a slot is provided in the middle of the upper surface of the support base plate. The inner diameter of the slot is adapted to the outer diameter of the load-bearing cylinder. A central hole is provided in the slot. An insert post is fixed on the lower surface of the load-bearing cylinder, and the outer diameter of the insert post is adapted to the inner diameter of the central hole.

[0018] With the above technical solution, the bottom of the load-bearing cylinder is located in the slot, providing stable bottom support and distributing the upper load to the support base plate through a larger contact area.

[0019] Furthermore, an inner rod is fixed to the lower surface of the second ear plate, the inner rod extends downward into the interior of the load-bearing cylinder, a first magnetic ring is embedded in the lower surface of the inner rod, and a second magnetic ring is embedded in the inner bottom wall of the load-bearing cylinder, the magnetic poles of the first magnetic ring and the second magnetic ring being the same.

[0020] Through the above technical solution, when the inner rod moves downward and brings the first and second magnetic rings closer together, an attractive force is generated, which can effectively guide them to always be in the center position of the load-bearing cylinder.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. The modular design not only facilitates production and assembly, but also allows for the selection and installation of different styles of fixing plates according to actual needs, improving assembly efficiency. By sliding two extension plates in the sliding groove of the fixing plate, the support area is expanded in the horizontal direction, enabling the fixing plate to adapt to different sizes of stalls, thereby ensuring the stability of the stall support and improving its versatility in use. 2. By connecting the first ear plate and the second ear plate, the upper fixing plate, extension plate, load-bearing cylinder, and support base plate are all separated into independent modules, which facilitates separate processing. The design of the bottom of the limit rod allows it to be naturally guided into the inner cavity of the load-bearing cylinder during installation. Attached Figure Description

[0024] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0026] Example 1: Reference Figure 1 A modular combined hardware connector includes a support base plate 1, a countersunk hole 2 opened on the support base plate 1, and a load-bearing cylinder 3 fixed in the countersunk hole 2. The load-bearing cylinder 3 is a hollow cylinder with its middle part recessed downward to form a concave arc surface. A support adjustment mechanism 4 is provided on the upper side of the load-bearing cylinder 3 to adapt to different usage requirements. An installation mechanism 5 is provided between the load-bearing cylinder 3 and the support adjustment mechanism 4 on the opposite side for connection.

[0027] It should be noted that mounting holes are symmetrically provided at both ends of the upper surface of the support base plate 1. Fasteners such as bolts are passed through the mounting holes on the support base plate 1 to firmly fix it to the external mounting base. A slot is provided in the middle of the upper surface of the support base plate 1. The inner diameter of the slot is adapted to the outer diameter of the load-bearing cylinder 3. A central hole is provided in the slot. A post is fixed on the lower surface of the load-bearing cylinder 3. The outer diameter of the post is adapted to the inner diameter of the central hole. This achieves precise horizontal positioning of the load-bearing cylinder 3 and prevents it from swaying laterally during use. At the same time, the bottom end face of the load-bearing cylinder 3 contacts the bottom surface of the slot, providing stable support.

[0028] refer to Figure 2 and Figure 3 The support adjustment mechanism 4 includes a fixed plate 41 disposed on the upper side of the load-bearing cylinder 3 and two extension plates 42 slidably connected to the fixed plate 41. The left and right sides of the fixed plate 41 are provided with sliding grooves 43 for the extension plates 42 to slide. The front and rear sides of the extension plates 42 are provided with positioning elements for positioning the extension plates 42 in the horizontal direction.

[0029] The positioning components include springs 44 fixed on the front and rear sides of the extension plate 42. Positioning posts 45 are fixed on the opposite sides of the springs 44 on both sides. Multiple positioning holes 46 are provided at both ends of the outer surface of the fixing plate 41. The outer diameter of the positioning posts 45 is matched with the inner diameter of the positioning holes 46. The positioning posts 45 on both sides are located on the same straight line to ensure that the positioning posts 45 at both ends of the extension plate 42 move synchronously during the extension or retraction process, thus avoiding jamming.

[0030] When adjusting the extension length of the extension plates 42 at both ends, the operator first presses the positioning pins 45 on both the front and rear sides. The positioning pins 45 compress the springs 44 and move towards the side closer to the extension plate 42 until the positioning pins 45 are completely disengaged from the positioning holes 46, thus releasing the lock between the extension plate 42 and the fixed plate 41. At this time, the operator can push and pull the extension plate 42 to make it slide horizontally along the sliding grooves 43 on the fixed plate 41 to adjust its extension length. When the extension plate 42 slides to the target position and the positioning pins 45 at the front and rear are aligned with the corresponding positioning holes 46, the operator releases the pressure on the positioning pins 45. Under the elastic force generated by the springs 44 restoring their deformation, the positioning pins 45 on both sides enter the new positioning holes 46, locking the extension plate 42 in the current position, thus completing the adjustment of the extension length of the extension plate 42.

[0031] refer to Figure 2 , Figures 4 to 6The installation mechanism 5 includes a first ear plate 51 fixed to the top of the outer surface of the load-bearing cylinder 3. Two threaded holes 52 are opened at both ends of the upper surface of the first ear plate 51. A second ear plate 53 is fixed to the lower surface of the fixing plate 41. Two hexagonal holes 54 are opened at both ends of the upper surface of the fixing plate 41 and the second ear plate 53. A limit rod 55 is fixed to the lower surface of the second ear plate 53. The limit rod 55 can effectively resist lateral force and enhance the anti-overturning ability. The limit rod 55 is located inside the load-bearing cylinder 3 and its lower end has an isosceles trapezoidal cross-section.

[0032] First, align the upper support adjustment mechanism 4 with the lower load-bearing cylinder 3. Insert the limiting rod 55 into the inner cavity of the load-bearing cylinder 3 to ensure that the first ear plate 51 and the second ear plate 53 fit tightly together. The operator then passes the bolt through the hexagonal holes 54 on the fixing plate 41 and the second ear plate 53 from above, and finally screws it into the pre-made threaded hole 52 on the first ear plate 51, so that the first ear plate 51 and the second ear plate 53 are firmly pressed together.

[0033] refer to Figure 1 , Figure 4 and Figure 6 The upper surface of the fixing plate 41 is provided with a mounting groove 61. The inner cavity of the mounting groove 61 is threadedly connected to a first screw 62. The lower surface of the first screw 62 passes through the mounting groove 61 and extends into the limiting rod 55. Multiple one-to-one corresponding hexagonal holes 54 and multiple threaded holes 52 are threadedly connected to the same second screw 63.

[0034] It should be noted that the No. 1 screw 62 is screwed into the upper mounting groove 61, and its bottom goes down and is screwed into the internal thread at the top of the limiting rod 55. When the No. 1 screw 62 is tightened, the strong pulling force it generates will pull the fixing plate 41 and the limiting rod 55 together, so that the No. 2 ear plate 53 and the No. 1 ear plate 51 in the middle are tightly clamped in the middle to prevent shaking.

[0035] Example 2: Reference Figure 7 This embodiment is largely the same as Embodiment 1, except that: an inner rod 71 is fixed on the lower surface of the second ear plate 53, the inner rod 71 extends downward into the interior of the load-bearing cylinder 3, a first magnetic ring 72 is embedded on the lower surface of the inner rod 71, and a second magnetic ring 73 is embedded in the inner bottom wall of the load-bearing cylinder 3, and the magnetic poles of the first magnetic ring 72 and the second magnetic ring 73 are the same.

[0036] When the fixed plate 41 moves the inner rod 71 downward, it will cause the first magnetic ring 72 and the second magnetic ring 73 to move closer together, thereby generating an attraction force, which can quickly guide the inner rod 71 into the load-bearing cylinder 3 and keep it always in the center of the load-bearing cylinder 3.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
