Description

Technical Field

[0001] The present invention relates to the technical field of hardware transfer connectors, in particular to a hardware transfer connector with adjustable connection angle. Background Art

[0002] A hardware transfer connector is a common object connection component that can connect and reinforce two separate objects in a parallel, vertical or butt-jointed manner to achieve controlled assembly between separate objects. It is widely used in assembly structures. Application number CN202020252787.1 is a highly stable hardware connector that solves the problem of existing hardware connectors that the angle between the first connecting plate and the second connecting plate cannot be adjusted according to actual requirements, thereby increasing the applicability of the connector.

[0003] However, the rotating structure of the hardware connector in the above document corresponds to the corner position of the overall connector, which is installed between two groups of profile components assembled vertically or at an angle. The corner structure is correspondingly set at the joint position of the two groups of profile components, which affects the observation of the fit of the two groups of profile components. In addition, the rotating structure is limited only by the outer pushing structure. The connection stability between the two assembled groups of profile components is limited. The large load-bearing force on the two groups of profile components will affect the rotation limit state of the hardware connector, making the hardware connector connection relatively loose, which is not conducive to its assembly and use.

[0004] Therefore, it is necessary to design a hardware transfer connector with adjustable connection angle to address the above problems. Summary of the Invention

[0005] The object of the present invention is to provide a hardware transfer connector with an adjustable connection angle to solve the problem proposed in the above background technology, but the rotation structure of the hardware connector in the above document corresponds to the corner position of the overall connector, and is installed between two groups of profile components assembled vertically or at an angle. The corner structure is correspondingly arranged at the docking position of the two groups of profile components, which affects the observation of the fit of the two groups of profile components. In addition, the rotation structure is limited only by the outer pushing structure, and the connection stability between the two assembled groups of profile components is limited. The large load-bearing force on the two groups of profile components will affect the rotation limit state of the hardware connector, making the connection of the hardware connector relatively loose, which is not conducive to its assembly and use.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a hardware transfer connector with adjustable connection angle, wherein the main connection structure of the hardware transfer connector is composed of a transverse connecting frame and a longitudinal connecting frame, wherein the bottom surfaces of the transverse connecting frame and the longitudinal connecting frame are arranged in affixed relation to the mounting plane, an outer limit frame is fixed to the side of the transverse connecting frame, and the inner side of the outer limit frame is connected to the side of the inner transmission cylinder via a drive shaft, and the inner transmission cylinder is fixedly mounted to the side of the longitudinal connecting frame;

[0010] Preferably, the side of the longitudinal connecting frame forms a rotating structure with the transverse connecting frame through an outer limit frame, a drive shaft and an inner transmission cylinder, and the inner transmission cylinder is rotatably embedded in the inner side of the outer limit frame. The corresponding rotation of the transverse connecting frame and the longitudinal connecting frame can be controlled by the outer limit frame and the inner transmission cylinder, so that the hardware transfer connection can be adjusted to multiple connection angles for assembly.

[0011] Preferably, the upper end of the support rod and the protective cover fixed on the side of the longitudinal connecting frame form a rotating structure, and the lower end of the support rod and the protective cover fixed on the upper end of the internal threaded block form a rotating structure, and the internal threaded block and the regulating screw form a threaded transmission structure to control the rotation of the regulating screw. Under the action of the threaded transmission structure, the internal threaded block can be controlled to move laterally, and the two ends of the support rod can be controlled to rotate. The support rod can promote the rotation adjustment between the longitudinal connecting frame and the transverse connecting frame.

[0012] Preferably, the sides of the transverse connecting frame and the longitudinal connecting frame are further provided with guide rails, positioning straight rods and inner circular groove plates:

[0015] The inner circular groove plate is fixedly mounted on the inner side of the transverse connecting frame and the longitudinal connecting frame, and the interior of the inner circular groove plate is connected through a sliding frame, and the exterior of the sliding frame is sleeved with a limiting spring.

[0016] Preferably, the side surface of the side panel forms a directional sliding structure through a guide slider and a guide rail, and the side surface of the side panel and the slide frame are fixed to form an integrated driving structure. When the positioning straight rod rotates, it can push the side panel and the guide slider to slide correspondingly on the side of the guide rail.

[0017] Preferably, one side of the positioning straight rod and the side plate form a rotating structure, and the other side of the positioning straight rod is rotationally connected to the side of the inner transmission cylinder through a positioning bent rod, and two groups of positioning bent rods are arranged on the outside of the inner transmission cylinder.

[0018] Preferably, the sliding frame and the inner circular groove plate form a through sliding structure, and the side of the inner circular groove plate forms an elastic structure with the side plate through a limit spring.

This partial structure forms an assembly anti-slip structure, which can improve the corresponding fit between the transverse connecting frame and the longitudinal connecting frame and the installation plane, and assist in the installation.

[0020] Preferably, the lower surface of the plastic suction cup extends out of the lower surface of the transverse connecting frame, and the plastic suction cup is evenly distributed in a matrix inside the embedded groove.

[0021] Preferably, the arc-shaped convex discs are arranged at equal angles on the lower surface of the pressure rod, and the lower surface of the pressure rod has an arc-shaped structure. The arc-shaped convex disc at the lower end of the pressure rod is pressed and arranged on the installation plane surface, which can increase the friction between the suction cup and the plane and avoid the suction cup from being misplaced, moving, leaking and loosening.

[0022] Compared with the prior art, the present invention has the following beneficial effects: the hardware transfer connector with adjustable connection angle adopts a new structural design, so that the device can be provided with a connection angle adjustment structure, and the corner structure and the joint surface of the assembled profile component are separated from each other, and the corner adjustment structure is provided with a double limit structure, the specific contents of which are as follows:

[0023] 1. This hardware transfer connector with adjustable connection angle is equipped with an angle adjustment structure. The transverse connecting frame and the longitudinal connecting frame are respectively arranged on the surfaces of the two assembled profile components. According to the mutual assembly angle between the profile components, the rotation of the control screw is controlled. Under the action of the threaded transmission structure, the internal threaded block is pushed to move horizontally. At this time, the rotation of the two ends of the support rod pushes the longitudinal connecting frame to rotate accordingly, thereby adjusting the corresponding angle between the longitudinal connecting frame and the transverse connecting frame. In this way, the hardware transfer connector can be adjusted according to the corresponding angle of the assembled profiles, and has a wide assembly applicability.

[0024] 2. This hardware transfer connector with adjustable connection angle is equipped with a rotation limit structure. After the longitudinal connecting frame and the transverse connecting frame are controlled to rotate relative to each other, the inner transmission cylinder is embedded in the inner part of the outer limit frame and rotates accordingly. The inner transmission cylinder drives the positioning bent rod and the positioning straight rod connected to the outer side to rotate relative to each other. The positioning straight rod pushes the side plate and the sliding frame to move in a certain direction. The side plate presses the limit spring to the side. This part of the movable elastic structure can generate a reverse thrust on the rotation position of the inner transmission cylinder, thereby limiting the rotation adjustment angle of the inner transmission cylinder and maintaining the stability of the corresponding angle after the hardware transfer connector is rotated and adjusted;

[0025] 3. The hardware transfer connector with adjustable connection angle is provided with an anti-slip structure for installation. The horizontal connecting frame and the vertical connecting frame are fitted on the installation plane. The plastic suction cups installed on the ground for the horizontal connecting frame and the vertical connecting frame are pressed downward and set on the installation plane. The plastic suction cups are pressed to discharge air outward and are adsorbed on the installation plane, which can play a certain anti-slip role in installation. The pressure rod inside the plastic suction cup is pressed downward to push the arc-shaped convex disc to fit on the installation plane. Under the action of the concave and convex surface, the anti-slip structure is more stably fitted on the installation plane, thereby improving the stability of the assembly application of the hardware intermediate connecting frame.

[0041] In this example, the side of the longitudinal connecting frame 2 forms a rotating structure with the transverse connecting frame 1 through the outer limit frame 3, the drive shaft 4 and the inner transmission cylinder 5, and the inner transmission cylinder 5 is rotatably engaged with the inner side of the outer limit frame 3; the upper end of the support rod 11 and the protective cover 10 fixed to the side of the longitudinal connecting frame 2 form a rotating structure, and the lower end of the support rod 11 and the protective cover 10 fixed to the upper end of the internal thread block 9 form a rotating structure, and the internal thread block 9 and the regulating screw 8 form a threaded transmission structure;

[0042] The transverse connecting frame 1 and the longitudinal connecting frame 2 are respectively set on the surfaces of the two groups of profile components that need to be assembled. According to the corresponding angles of the assembly joint surfaces between the two groups of profile components, the assembly angle between the transverse connecting frame 1 and the longitudinal connecting frame 2 is adjusted, and the rotation of the regulating screw 8 is controlled. Under the action of the threaded transmission structure, the internal threaded block 9 is pushed to be sleeved on the outside of the regulating screw 8 and move horizontally. At this time, the upper and lower ends of the support rod 11 are both embedded in the interior of the protective cover 10 and rotate accordingly. The upper end of the support rod 11 pushes the longitudinal connecting frame 2 to rotate sideways. At this time, the inner transmission cylinder 5 is embedded in the interior of the outer limit frame 3 and rotates accordingly through the drive shaft 4, adjusting the corresponding rotation angle between the longitudinal connecting frame 2 and the transverse connecting frame 1, so that the hardware transfer connector can be flexibly adjusted according to the corresponding angle between the assembled profiles.

[0043] The sides of the transverse connecting frame 1 and the longitudinal connecting frame 2 are also provided with guide rails 12, positioning straight rods 15 and inner circular groove plates 17: the guide rails 12 are fixedly mounted on the inner sides of the transverse connecting frame 1 and the longitudinal connecting frame 2, and the outer side of the guide rails 12 is fitted with a guide slider 13, and the side of the guide slider 13 is fixedly mounted with a side plate 14; the positioning straight rod 15 is connected to one end of the side plate 14, and the side of the positioning straight rod 15 is fixedly connected with a positioning bent rod 16, and the side of the positioning bent rod 16 is connected to the outer side wall of the inner transmission cylinder 5; the inner circular groove plate 17 is fixedly mounted on the inner sides of the transverse connecting frame 1 and the longitudinal connecting frame 2, and the inner circular groove plate 17 is fixedly mounted on the inner sides of the transverse connecting frame 1 and the longitudinal connecting frame A slide frame 18 is connected through the interior, and a limit spring 19 is installed on the outside of the slide frame 18; the side of the side plate 14 forms a directional sliding structure with the guide slide 13 and the guide rail 12, and the side of the side plate 14 is fixed to the slide frame 18 as an integrated drive structure; one side of the positioning straight rod 15 and the side plate 14 form a rotating structure, and the other side of the positioning straight rod 15 is rotatably connected to the side of the inner transmission cylinder 5 through a positioning bent rod 16, and two groups of positioning bent rods 16 are provided on the outside of the inner transmission cylinder 5; the slide frame 18 and the inner circular groove plate 17 form a through-sliding structure, and the side of the inner circular groove plate 17 forms an elastic structure with the side plate 14 through a limit spring 19;

[0044] When controlling the corresponding rotation of the transverse connecting frame 1 and the longitudinal connecting frame 2, the inner transmission cylinder 5 drives the two ends of the positioning bent rod 16 and the positioning straight rod 15 connected on the outside to rotate accordingly. The positioning straight rod 15 is connected to the side of the side plate 14 and rotates, pushing the side plate 14 to move directionallly along the direction of the guide slide rail 12 through the guide slider 13. The side of the side plate 14 pushes the slide frame 18 to slide correspondingly through the inside of the inner circular groove plate 17, and the side plate 14 presses the limit spring 19 to the side. Through this part of the moving elastic structure, a certain reverse thrust can be formed on the rotating positioning straight rod 15 and the positioning bent rod 16, and the reverse thrust is transmitted to the inner transmission cylinder 5, so that this part of the structure can limit the rotation between the transverse connecting frame 1 and the longitudinal connecting frame 2, and maintain the stability of the hardware transfer connector after the angle rotation is adjusted.

[0045] An embedded groove 20 is provided inside the bottom surface of the transverse connecting frame 1 and the longitudinal connecting frame 2, and a plastic suction cup 21 is fixedly installed on the inner top surface of the embedded groove 20, and a pressure rod 22 is fixed in the middle position of the inner part of the plastic suction cup 21, and an arc-shaped protrusion 23 is fixed to the lower end side of the pressure rod 22; the lower surface of the plastic suction cup 21 extends outside the lower surface of the transverse connecting frame 1, and the plastic suction cups 21 are evenly distributed in a matrix inside the embedded groove 20; the arc-shaped protrusions 23 are distributed at equal angles on the lower surface of the pressure rod 22, and the lower surface of the pressure rod 22 has an arc-shaped structure;

[0046] When the transverse connecting frame 1 and the longitudinal connecting frame 2 are controlled to fit together on the installation plane of the profile component, the transverse connecting frame 1 and the longitudinal connecting frame 2 are pressed downward, so that the plastic suction cup 21 embedded in the bottom surface thereof is subjected to a downward extrusion force, and the plastic suction cup 21 discharges air outward and is adsorbed on the installation plane of the profile component, thereby improving the adsorption stability of the transverse connecting frame 1 and the longitudinal connecting frame 2 assembled with the surface of the profile component, and when the plastic suction cup 21 is pressed downward, it pushes the pressure rod 22 and the arc-shaped convex disc 23 to fit and extrude on the installation plane. The lower end of the pressure rod 22 is in a concave-convex structure through the arc-shaped convex disc 23, and the surface roughness is relatively large. It is fit on the installation plane of the profile, which can improve the friction between the plastic suction cup 21 and the installation plane of the profile, and play a certain anti-slip role in the assembly of the hardware transfer connector.

[0047] Working principle: When using this device, according to Figure 1-9 The structure shown in , controls the two groups of profiles to dock with each other, and fits the horizontal connecting frame 1 and the longitudinal connecting frame 2 on the surface of the profile component respectively. During the bonding process, the plastic suction cups 21 embedded in the bottom surfaces of the horizontal connecting frame 1 and the longitudinal connecting frame 2 squeeze the air outward and adsorb it on the installation plane, thereby improving the assembly stability between the hardware transfer connector and the profile component, and the rotation position between the horizontal connecting frame 1 and the longitudinal connecting frame 2 is separated from the docking surface between the two groups of profile components, which is convenient for the staff to directly observe the assembly angle between the docking surfaces of the two groups of profile components. According to the docking angle of the profile, the rotation angle between the horizontal connecting frame 1 and the longitudinal connecting frame 2 is adjusted, and the control screw 8 is controlled to rotate. Under the action of the threaded transmission structure, the internal threaded block 9 moves laterally. At this time, the two ends of the support rod 11 at the upper end of the internal threaded block 9 rotate accordingly, and the support rod 11 pushes the longitudinal connecting frame 2 to rotate sideways, and the rotation angle between the longitudinal connecting frame 2 and the horizontal connecting frame 1 is adjusted to correspond to the assembled profile component. Finally, the hardware transfer connector and the surfaces of the two groups of assembled profile components are fixed to each other by locking the bolt key 6;

[0048] During the process of adjusting the connection angle of the hardware transfer connector, the inner transmission cylinder 5 is embedded in the inner part of the outer limit frame 3 and rotates. The inner transmission cylinder 5 pushes the outer positioning bent rod 16 and the positioning straight rod 15 to rotate accordingly, so that the positioning straight rod 15 pushes the side plate 14, the guide slider 13 and the slide frame 18 to slide sideways, and the side plate 14 presses the limit spring 19 to the side. Under the action of the elastic moving structure, the rotation angle of the inner transmission cylinder 5 can be limited, thereby limiting the connection angle of the hardware transfer connector. Combined with the threaded limiting effect of the internal threaded block 9 and the regulating screw rod 8, the double limiting structure can prevent the hardware transfer connector from loosening due to the bearing pressure of the two groups of profile components, thereby improving the stability of the assembly connection of the hardware transfer connector.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
