Description

Technical Field

[0001] The utility model belongs to the technical field of guide rail connectors, and in particular relates to a connector that is easy to install. Background Art

[0002] When installing and fastening sheet metal parts such as channel steel, they are generally fastened directly with bolts or by welding. However, in some places, due to space constraints, it is inconvenient to install bolts. If welding is used, a welding machine and power supply need to be prepared, which is also inconvenient for outdoor and high-altitude operations.

[0003] To this end, the utility model patent with publication number CN208123872U discloses a press-nut type connection mechanism. It includes a toothed channel steel, a mounting base and a connecting fastener. The toothed channel steel is installed on the mounting base, and the toothed channel steel and the mounting base are fastened together by the connecting fastener. The connecting fastener includes a pressing plate, a bolt, a toothed channel steel nut, and a compression spring. The pressing plate is installed on the top long hole of the U-shaped bracket, the bolt passes through the pressing plate, the toothed channel steel nut is installed on the bolt, and the toothed channel steel nut is located inside the toothed channel steel.

[0004] This solution makes the nut rectangular, rounded corners on the diagonals, serrated strips on the upper surface, and toothed hems on the connecting channel steel to cooperate with the toothed nut, so that the installation is firm and reliable. At the same time, the connector of the push-type nut in this solution increases the preload by setting a spring, and can be assembled by push-type, making the connector easy to install. However, when installing the connector in this solution, it is necessary to press the bolt downward first, and then rotate the bolt 90°. At this time, the bolt drives the toothed channel steel nut to rotate, so that the toothed channel steel nut is stuck by the toothed channel steel, and then let go, and finally tighten the bolt to fix it.

[0005] It can be seen that the device does not only need to press the bolt manually during operation, but also needs to rotate the bolt manually to drive the nut to rotate. However, when the bolt is rotated manually, the nut is on the inner side of the guide rail and the specific rotation angle cannot be observed. On the one hand, corresponding teeth need to be set on the channel steel and the nut at the same time, so as to determine the rotation angle by matching between the teeth, which greatly increases the process difficulty and cost; on the other hand, the rotation cannot be too fast, because it is necessary to find the rotation angle by feel to avoid too fast rotation resulting in the teeth on the channel steel not corresponding to the teeth on the nut, that is, the whole operation process is relatively cumbersome, and since it is impossible to judge whether the nut has entered the inside of the channel steel during operation, it is usually necessary to press the bolt to the bottom as much as possible when pressing. At this time, the worker's pressing force is required to be high. At this time, rotating the bolt under the pressing state is difficult to operate and greatly increases the workload, especially when a large number of connectors need to be installed on the finished support and hanger, the workload of pressing and rotating with great force increases exponentially.

[0006] Therefore, there is an urgent need for a connector with a simple structure and simple and convenient operation. Utility Model Content

[0007] The purpose of the utility model is to provide a connector that is easy to install, so as to partially alleviate or solve the above-mentioned problem, thereby making the installation of the connector simpler and more convenient.

[0009] When the fixing block is inserted into the clamping structure, the bracket body, the limiting protrusion and the bending portion cooperate to clamp the fixing block;

[0010] When the elastic member is sleeved on the fastener and the fastener is passed through the mounting hole to be threadedly connected with the fixing block, the two ends of the elastic member are respectively abutted against the head of the fastener and the limiting bracket, so that the connecting member is in a pre-assembled state;

[0011] When the fastener is pressed to move the fixing block in the height direction of the fastener, the bending portion is deformed under the squeezing action of the fixing block, and drives the fixing block to detach from the clamping structure from the gap and rotate into the limiting groove for limiting.

[0012] As an improvement, the bracket body includes a first body fixedly fitted with the mounting seat, and two second bodies extending from both sides of the length direction of the first body along the height direction of the limiting bracket to form an opposite arrangement; the two ends of the second body extend along the extension direction of the second body to form the limiting protrusion; wherein the limiting protrusions on the two diagonals extend along the direction close to the limiting protrusions on the opposite sides to form parallel and deformable bending parts.

[0013] As an improvement, the limiting bracket is in the shape of a rectangular parallelepiped with a hollow interior as a whole.

[0014] As an improvement, the bending portion is in a rectangular shape, and the width of the bending portion is the same as the width of the limiting protrusion, and a gap is left between the free end of the bending portion and the opposite limiting protrusion for the fixing block to pass through.

[0015] As an improvement, the fixing block is in the shape of a cuboid, the threaded hole is arranged at the center of the fixing block, and two radial edges of the fixing block are smoothly transitioned.

[0016] As an improvement, the width of the fixing block is the same as the width between two limiting protrusions arranged on the same side along the length direction of the limiting bracket.

[0017] As an improvement, the height and width of the fixing block are respectively consistent with the inner height and width of the limiting bracket.

[0018] As an improvement, the mounting hole is a circular light hole, and the inner diameter of the light hole is larger than the maximum diameter of the screw portion of the fastener.

[0019] As an improvement, the bending portion is a metal spring with elasticity.

[0020] As an improvement, auxiliary mounting plates are respectively arranged on the same side of the first mounting plate and the second mounting plate, and a reinforcing plate is arranged between the two auxiliary mounting plates.

[0021] The principle and beneficial effects of the utility model are:

[0022] The connecting piece with the above structure is simple and convenient to operate by pre-installing the connecting fastener on the mounting seat and then installing the connecting piece as a whole on other components when in use.

[0023] Specifically, first, the fixing block is fixed to the limiting bracket and the pre-installation of the connecting part is completed. When in use, the pre-installed part is installed on other parts. By pressing the fastener in the radial direction, the fastener drives the fixing block to move downward, and the bent portion is deformed under the extrusion of the fixing block, so that the gap between the bent portion and the limiting protrusion becomes larger, and the fixing block is separated from the limiting bracket from the two gaps set opposite to each other. At the same time, under the joint action of the fastener and the limiting bracket, the fixing block automatically rotates during the downward movement driven by the elastic bent portion, and enters the limiting groove for fixation. By adjusting the direction of the fixing block, the width of the entire connecting fastener is changed, thereby achieving the purpose of fixation.

[0024] In summary, this solution makes the installation of the connector more convenient and quick by providing an automatically turned one-touch press connecting fastener. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Embodiment 1

[0044] This embodiment is basically as shown in Figures 1-5:

[0045] like Figure 1a , Figure 1b As shown, the present solution provides a connector that is easy to install, including a mounting base 1 and at least two connecting fasteners 2. The mounting base 1 includes a first mounting plate and a second mounting plate that are vertically connected, and at least one mounting hole 11 is respectively provided on the first mounting plate and the second mounting plate.

[0046] In some embodiments, auxiliary mounting plates are respectively provided on the same side of the first mounting plate and the second mounting plate, and the two auxiliary mounting plates are respectively maintained perpendicular to the first mounting plate and the second mounting plate, so that an installation space for accommodating the first guide rail is formed between the auxiliary mounting plate and the first mounting plate, and correspondingly, an installation space for accommodating the second guide rail is formed between the other auxiliary mounting plate and the second mounting plate; in order to increase the strength of the mounting plate, a reinforcing plate is provided between the two auxiliary mounting plates.

[0047] By cooperating with a mounting seat having a vertical structure and a plurality of connecting fasteners, two mutually perpendicular guide rails (such as a first guide rail and a second guide rail) can be fixed to obtain the bracket assembly.

[0048] like Figure 2a-2c As shown, the connecting fastener includes a fastener 21, an elastic member 22, a fixing block 23 and a limiting bracket 24. The fixing block 23 is provided with a threaded hole matching the fastener. The fastener can pass through the mounting hole and the threaded hole in sequence and be threadedly connected to the fixing block. The elastic member 22 is sleeved on the fastener 21, and the two ends of the elastic member 22 are respectively abutted against the head of the fastener 21 and the limiting bracket 24.

[0049] In some embodiments, the fastener is a bolt, and the elastic member is a spring.

[0050] In some embodiments, the mounting hole 11 is a circular light hole, and the inner diameter of the light hole is larger than the maximum diameter of the screw portion of the fastener (preferably slightly larger than the maximum diameter of the fastener rod), so as to ensure that the fastener and the elastic member can easily pass through the mounting hole, while also playing a certain limiting role on the fastener and the spring to prevent them from being excessively offset in the mounting hole.

[0051] like Figure 4 As shown, the limiting bracket 24 includes a bracket body fixed on the mounting seat, and the bracket body is provided with a through hole 243 for the fastener to move up and down, and the two ends on both sides of the length direction of the bracket body extend along its height direction to form limiting protrusions 244, and a limiting groove is formed between the two limiting protrusions 244 on the same side, wherein the limiting protrusions on the two diagonals extend along the width direction of the bracket body to form a deformable bending portion 245, and the cross-section of the mutually connected bending portions and the limiting protrusion is L-shaped, so that the bracket body, the limiting protrusion 244 and the bending portion 245 cooperate to form a clamping structure for clamping the fixed block.

[0052] In some embodiments, the inner diameter of the through hole 243 is smaller than the diameter of the elastic member, so that the elastic member can be fixed on the upper surface of the bracket body after passing through the mounting hole.

[0053] In some embodiments, the bending portion is an elastic metal spring to ensure that after the fixing block is detached from the limiting bracket, the bending portion can be reset without affecting the secondary use of the connecting piece.

[0054] In some embodiments, to facilitate the detachment of the fixing block from the clamping structure, a gap is left between the free end of the bent portion and the adjacent limiting protrusion on the opposite side for the fixing block to pass through. When the bent portion is deformed under the action of the fixing block, the gap gradually becomes larger and allows the fixing block to pass through.

[0055] In some embodiments, the bracket body can be specifically divided into a first body 241 that is fitted and fixed to the mounting seat, and a second body 242 that extends from both sides of the length direction of the first body 241 along its height direction; the height of the second body 242 is lower than the height of the fixed block, and the second body 242 includes two sub-bodies respectively arranged on both sides of the first body 241, and the two ends of the two sub-bodies continue to extend along the extension direction of the sub-bodies to form four limiting protrusions 244, and a limiting groove is formed between the two limiting protrusions 244 arranged on the same sub-body, and the two limiting grooves 246 jointly limit the fixed block after turning.

[0056] In some embodiments, see Figure 4 , with the center of the limit bracket 24 as the origin, the direction of the X-axis in the figure is the length direction of the limit bracket (also known as the axial direction in the following text), the direction of the Y-axis is the width direction of the limit bracket, and the Z-axis is the height direction of the limit bracket (also known as the radial direction in the following text).

[0057] In some embodiments, the upper surface of the first body 241 can be fixed to the mounting base by spot welding.

[0058] In some embodiments, Figure 3 As shown, the fixing block 23 is in the shape of a rectangular parallelepiped, and the threaded hole 231 is arranged at the center position of the fixing block 23. In order to facilitate the fixing block 23 to be separated from the gap, the two edges of the fixing block 23 are smoothly transitioned to form rounded edges. When the fixing block is fixed in the clamping structure, the rounded edges correspond to the gap of the limiting bracket, thereby making it easier for the fixing block to pass through the gap.

[0059] In some embodiments, the spacing between the two sub-bodies and the width of the limiting groove are the same as the width of the fixing block, so that the fixing block can be clamped and fixed in different states (including pre-assembly state and fixed state) of the connecting fastener.

[0060] In some embodiments, the limiting bracket is an overall rectangular frame structure with a hollow interior, and its two side surfaces in the width direction are hollowed out to form openings to facilitate the insertion of the fixing block into the limiting bracket through the openings; its limiting groove is located on the two side walls in the length direction of the limiting bracket, so that the fixing block can be fixed by the cavity inside the limiting bracket in the pre-assembled state, and when the fixing block is separated from the clamping structure and rotated 90°, the limiting block can be fixed by the limiting groove.

[0061] When the fastener is pressed downward, the bent portion is squeezed by the fixing block to deform, and the deformed bent portion exerts a force on the fixing block. Figure 2a The force in the direction pointed by the middle arrow can be decomposed into two forces, radial and axial. The radial force can be offset by the force in the opposite direction of the radial force generated when pressing, and the axial force can drive the fixed block to rotate in the first direction during the radial downward movement. When the bolt is no longer pressed, the bent portion is reset under the action of the elastic force, thereby generating an upward thrust on the fixed block, so that after the fixed block is separated from the limiting bracket, the fixed block automatically enters the limiting groove under the action of this force and is fixed.

[0062] Embodiment 2

[0063] Based on the connecting piece in the first embodiment, the present invention also provides a bracket assembly, such as Figure 6 and Figure 7As shown, the component includes a connecting member with the above-mentioned structure, and a first guide rail 3 and a second guide rail arranged vertically. The two side walls of the first guide rail 3 and the second guide rail are respectively bent inward twice in sequence (first bent in the horizontal direction and then bent in the vertical direction) to form two inner folded edges opening toward the bottom surface of the guide rail.

[0064] When the connecting member is installed at the joint of the first guide rail and the second guide rail, the bent portion is parallel to the plane where the end of the inner folded edge is located, and the distance between the bent portion and the inner wall (bottom wall) of the first guide rail or the second guide rail is smaller than the distance between the plane where the end of the inner folded edge is located and the inner wall of the first guide rail or the second guide rail, so that the gap is located between the plane where the end of the inner folded edge is located and the inner wall (bottom wall) of the first guide rail or the second guide rail.

[0065] In some embodiments, the end of the inner folded edge is flush with the bottom of the limiting groove (that is, the bottom edge of the second body), so that when the fixing block is located in the limiting groove, the upper surface of the fixing block can simultaneously fit with the bottom of the limiting groove and the end of the inner folded edge, thereby achieving a better fixing effect.

[0066] The specific installation process of the bracket assembly (including two connecting fasteners, two guide rails, and a mounting plate) is described below:

[0067] When in use, first pre-assemble the connector (so that the connector fasteners appear as shown in the figure). Figure 2a The specific pre-installation includes the following steps: inserting the fixing block of the connecting fastener into the limiting bracket, at which time the limiting bracket wraps the fixing block, and then placing the elastic member in the position corresponding to the mounting hole, and then passing the fastener through the elastic member, one of the mounting holes of the mounting seat, the through hole and the threaded hole in turn, so that it is threadedly connected with the fixing block. At this time, the elastic member plays a pre-tightening role, so that the connecting member presents a relatively stable overall structure.

[0068] Then install the first guide rail to the first mounting plate. During the specific installation, first make the connecting piece correspond to the first guide rail. At this time, the fixing block of the connecting fastener on the first mounting plate is located between the two inner folded edges of the first guide rail. After determining the relative position of the first mounting plate and the first guide rail, press the fastener toward the bottom of the first guide rail along the height direction of the fastener. At this time, the elastic member is compressed, and the fixing block moves with the fastener. Under the extrusion of the fixing block, the bent portion is deformed, and the gap between the bent portion and the limiting protrusion becomes larger. While the fixing block gradually separates from the clamping structure, it automatically rotates under the thrust of the deformed bent portion. The fixing block rotates 90° along the limiting bracket and then automatically slides into the limiting groove and is fixed. Finally, the fastener is rotated to tighten the connecting fastener, so that the upper surface of the fixing block is tightly fitted with the end of the inner folded edge (the connecting fastener is Figure 2bIn the state shown in the figure), the fixing block and the mounting plate jointly clamp the first guide rail, thereby achieving relative fixation between the first guide rail and the connecting member.

[0069] Then, the first guide rail is mounted on the first mounting plate in the same manner, so that the first guide rail and the second guide tube are respectively mounted on the first mounting seat and the second mounting seat through two connecting fasteners to form a bracket assembly.

[0070] In summary, the present application provides a bracket assembly with a simple structure and convenient and quick installation.

[0071] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0072] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the purpose of the present invention and the claims, which all fall within the protection of the present invention.
