Description

Technical Field

[0001] The present application relates to the technical field of mechanical connectors, and in particular to a double-lock slider groove connection device that can be widely used in tunnel construction, airport construction, high-speed rail construction, civil building installation, machinery installation and other fields to achieve reliable structural connection and adjustment. Background Art

[0002] In the fields of building installation and mechanical installation, various structural connectors are usually encountered on the construction site. They bear the heavy responsibility of structural connection, so their performance must be reliable. Especially in tunnel construction, various joints need to be processed during the concrete pouring and anchor construction stages. The performance of these connectors must ensure reliability and non-deformation, and at the same time meet the connection requirements with the main structure. In addition, there is another type of connector called structural adjustment parts. Its main function in tunnel construction is to adjust construction materials such as concrete and anchors during the construction process.

[0003] The commonly used connection methods during on-site construction are bolt connection and embedded bolt connection. Among them, the bolt connection method is composed of three main parts: bolts, nuts, and washers. It is a way of transmitting preload force, which can enable the structure to be interconnected under load, and the relative position of the nut and bolt can be adjusted by rotation. The embedded bolt connection is to install the bolts made in advance according to the design requirements into the concrete through a certain method to form a whole. This connection method is relatively simple and easy to operate, but this connection method cannot be used in large-span and large-size concrete structures. Usually, the embedded bolt connection used in tunnel construction mainly uses embedded parts and steel bar anchor bolts. This connection method requires the embedded bolts to be anchored into the concrete first, and then during the concrete pouring process, the embedded bolts and steel bars are anchored together by the steel bar anchoring force.

[0004] Although the traditional connection structure can also meet most of the construction requirements, with the increase in usage requirements, the traditional connection structure is difficult to adjust during use, resulting in poor flexibility. Therefore, the current connection structure still has some usage defects, and it is necessary to propose a new technical solution to address the defects. Utility Model Content

[0008] Further in the above technical solution, a baffle and a washer are installed on the bolt, and the slider, baffle, washer and nut are arranged on the bolt in sequence. A through hole is formed in the middle of the baffle to allow the bolt to pass through. The baffle is placed above the slide rail and is a rectangular sheet structure.

[0009] Furthermore, the slide rail is composed of a bottom wall and two side walls, and the two side walls are relatively spaced apart on both sides of the bottom wall in the width direction; the side wall is composed of a vertical plate and a horizontal plate to form an L-shaped structure, one side of the vertical plate is connected to the bottom wall, and the other side is connected to the horizontal plate.

[0010] Furthermore, the transverse plates of the two side walls are arranged opposite to the bottom wall, and a gap is formed between the two transverse plates to allow the bolts to slide; the two side walls and one bottom wall form the track groove, and the cross-sectional shape of the track groove is a "convex" shape.

[0011] Furthermore, the slider is an elongated block, and the cross-sectional shape of the slider is a "convex" shape, and the height of the slider is smaller than the height of the track groove; when the bolt is screwed into the bottom wall of the slide rail, the slider moves upward along the bolt, so that the end of the bolt is pressed against the bottom wall of the slide rail, and the two shoulders of the slider are pressed against the cross plates of the two side walls, and the protrusion formed on the top of the slider is adapted to be inserted into the gap formed between the two cross plates, and the end face of the protrusion formed on the top of the slider is lower than the upper surface of the cross plate or flush with the upper surface of the cross plate.

[0012] Furthermore, one end surface of the bolt is a plane, and the other end of the bolt forms a wrench nut with a hexagon socket, and the bolt abuts against the bottom wall of the slide rail through the plane of its end.

[0013] Furthermore, a base is provided at the bottom of the slide rail.

[0014] Furthermore, one or more slide rails are arranged on the base.

[0015] Furthermore, the base includes legs arranged at the bottom of the slide rail.

[0016] Furthermore, the base includes a connecting plate arranged at the bottom of the slide rail.

[0017] Compared with the prior art, this application has at least the following beneficial effects:

[0018] 1. The double-lock slider groove type connection device provided by the present application comprises a slide rail and a sliding fixing assembly connected thereto, the sliding fixing assembly comprising a slide rail and a nut threadedly connected to a bolt, the length of the slide rail along the extension direction of the track groove in the slide rail being greater than the width of the track groove. Such a structural design enables the slide rail to only move back and forth linearly along the slide rail but not rotate. Therefore, when the bolt is screwed into the slide rail, the end face of the bolt can be pressed against the bottom wall of the slide rail, and the slide rail can be pressed against the top of the track groove. In addition, the present application also configures a nut on the bolt, and rotating the nut can further lock the bolt and the slide rail. Therefore, the double-lock slider groove type connection device provided by the present application has a double locking effect, a reliable mechanical connection in the installed state, and a high overall structural stability; furthermore, when the nut and the bolt are loosened, the double-lock slider groove type connection device provided by the present application can slide along the slide rail under the guiding action of the slide rail to adjust the fixed position of the sliding fixing assembly, and the slide rail will not fall off the slide rail. The adjustable structural design improves the flexibility of use of the device and improves its adaptability to various installation conditions.

[0019] 2. The bolts of the double-lock slider groove connection device provided in the present application are also equipped with baffles and washers. The setting of the baffles and washers can improve the connection stability of the bolts and nuts, and can indirectly fasten the nuts to the slide rails to play an anti-seismic role.

[0020] 3. The slider in the present application is a long strip block with a "convex" cross-sectional shape. The slide rail is composed of a bottom wall and two side walls. The two side walls are L-shaped structures. The cavity enclosed between the bottom wall and the two side walls is the track groove. The cross-sectional shape of the track groove is also "convex". During specific processing, the height of the slider can be made smaller than the height of the track groove. In this way, when the bolt is screwed into the bottom wall of the slide rail, the slider moves up along the bolt, so that the end of the bolt is pressed against the bottom wall of the slide rail, and the two shoulders of the slider are pressed against the cross plates of the two side walls, so that the slider and the bolt are respectively pressed against the upper and lower ends of the slide rail. The overall structure is reliably connected and has high stability.

[0021] 4. In the present application, the bolt abuts against the bottom wall of the slide rail through the flat surface at its end to ensure reliable locking. The other end of the bolt forms a wrench nut with a hexagon socket.

[0035] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0036] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0037] The terms such as "upper", "lower", "left", "right", "middle", etc. used in this application are usually used to facilitate intuitive understanding by comparing with the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product. Without departing from the technical concept disclosed in this application, changes in these relative positional relationships should also be regarded as the scope of this application.

[0038] In the construction process of subway, rail transit, construction industry, etc., embedded channels are often set. During installation, the mounting parts are fixed to the embedded channels by T-bolts. Figure 6 , is a schematic diagram of the state of the existing embedded groove and T-bolt assembly connection, T-bolt 02 includes a screw rod 021 and a limit block 022 connected to the end of the screw rod 021, the limit block 022 is a long strip, and the width of the limit block 022 is smaller than the notch of the embedded groove 01, therefore, the T-bolt 02 can be installed in the embedded groove 01 by rotating the T-bolt 02 to a suitable position, and then the T-bolt 02 is rotated to make the length direction of the limit block 022 parallel to the width direction of the embedded groove 01, and then the T-bolt 02 is fastened to the embedded groove 01 through the nut. The reliability of the connection between the embedded groove 01 and the T-bolt 02 directly affects the safety of the later use of the project, and this structural design has the following problems when applied: when the nut 03 is loose, the T-bolt is likely to rotate in the opposite direction and fall off. Therefore, the T-bolt currently used cannot fully meet the requirements of anti-loosening and anti-slip, and there are problems that the T-bolt is easy to fall off from the embedded groove and the positioning is inaccurate.

[0039] In order to solve the problems existing in the prior art, the present application provides a double-lock slider groove type connection device, and the structure of the device is described in detail below through specific embodiments.

[0040] Embodiment 1

[0041] The present embodiment provides a double-lock slider groove connection device, which mainly includes a slide rail 1 and a sliding fixing component 2 adapted to be installed on the slide rail 1, wherein the number of the sliding fixing components 2 can be determined according to usage requirements.

[0042] In this embodiment, the sliding fixing assembly 2 mainly includes a bolt 21 and a slider 22 and a nut 25 threadedly connected to the bolt 21. The slider 22 is adapted to be installed in the track groove 14 formed in the slide rail 1. The length of the slider 22 along the extension direction of the track groove 14 is greater than the width of the track groove 14. Therefore, the slider 22 is restricted to only reciprocate in the track groove 14 but not rotate, and the slider 22 cannot escape from the track groove 14. Therefore, the slider 22 in this embodiment can be a block of any shape, as long as it can reciprocate in the track groove 14 but cannot rotate or escape from the track groove 14. Based on this, the slider 22 in this embodiment can be a rectangular block, a block with both the upper and lower surfaces being trapezoidal, a block with both the upper and lower surfaces being parallelograms, etc.

[0043] When the bolt 21 is rotated so that the bolt 21 is screwed into the bottom wall 11 of the slide rail 1, the bolt 21 is threadedly connected with the slider 22, and the bolt 21 passes through the slider 22 and gradually presses against the bottom wall 11 of the slide rail 1. Since the slider 22 is restricted in the track groove 14 and cannot rotate, when the bolt 21 is screwed in, the slider 22 will move up along the bolt 21 and press against the top of the track groove 14 to form a first level of locking. Then, the nut 25 is installed and rotated to fasten the bolt 21 to the slide rail 1 to form a second level of locking. Therefore, the double-lock slider groove connection device provided in the present application can not only realize accurate adjustment and positioning installation, but also ensure the reliability of the connection and locking.

[0044] Embodiment 2

[0045] This embodiment provides a double-lock slider groove connection device, which includes all the contents of the first embodiment. Compared with the first embodiment, the second embodiment further includes a baffle 23 and a washer 24 installed on the bolt 21. Figure 1 , 2 The slider 22, the baffle 23, the washer 24 and the nut 25 are sequentially arranged on the bolt 21. The baffle 23 is a rectangular sheet structure, and a through hole is formed in the middle of the baffle 23 to allow the bolt 21 to pass through. After the baffle 23 is installed and connected, it is placed above the slide rail 1.

[0046] In this embodiment, the baffle 23 and the washer 24 are provided to improve the connection stability of the bolts and nuts, and the nut 25 can be indirectly fastened to the slide rail 1 to play an anti-vibration role.

[0047] Embodiment 3

[0048] This embodiment provides a double-lock slider groove connection device, which includes all the contents of the second embodiment. Compared with the second embodiment, this embodiment improves the structure and matching relationship between the slide rail 1 and the slider 22.

[0049] In this embodiment, see Figure 3 The slide rail 1 is composed of a bottom wall 11 and two side walls (a first side wall 12 and a second side wall 13), and the two side walls are arranged at intervals on both sides of the bottom wall 11 in the width direction; each side wall is formed into an L-shaped structure by a vertical plate and a horizontal plate. Taking the first side wall 12 as an example, one side of the first vertical plate 121 is connected to the bottom wall 11, and the other side is connected to the first horizontal plate 122. The horizontal plates of the two side walls (the first horizontal plate 122 and the second horizontal plate 132) are arranged opposite to the bottom wall 11, and a gap is formed between the two horizontal plates (the first horizontal plate 122 and the second horizontal plate 132) to allow the bolt 21 to slide.

[0050] In this embodiment, see Figure 3 A cavity surrounded by two side walls (a first side wall 12 and a second side wall 13) and a bottom wall 11 forms a track groove 14, and the cross-sectional shape of the track groove 14 is a "convex" shape.

[0051] In this embodiment, the slider 22 is a long strip-shaped block, and the cross-sectional shape of the slider 22 is a "convex" shape. The height of the slider 22 is less than the height of the track groove 14. When the bolt 21 is screwed into the bottom wall 11 of the slide rail 1, the slider 22 moves up along the bolt 21, so that the end of the bolt 21 is pressed against the bottom wall 11 of the slide rail 1, and the two shoulders of the slider 22 are pressed against the cross plates of the two side walls. The protrusion formed on the top of the slider 22 is adapted to be inserted into the gap formed between the two cross plates. Such a structural matching relationship can also play a limiting role. The end face of the protrusion formed on the top of the slider 22 is lower than the upper surface of the cross plate or flush with the upper surface of the cross plate, ensuring that the baffle and the top of the slide rail are reliably pressed against each other, such as Figure 4 .

[0052] Therefore, the double-lock slider groove connection device provided in this embodiment can make the slider 22 and the bolt 21 respectively press against the upper and lower ends of the slide rail 1 in the installed connection state, and the overall structure connection is reliable and has high stability. When the nut 25 and the bolt 21 are loosened, the slider 22 can slide along the slide rail 1 to adjust the fixed position of the sliding fixing assembly 2 under the guidance of the slider 22. The adjustable structural design of the slider 22 improves the flexibility of the device, can achieve accurate sliding positioning, and improves its adaptability to various installation conditions.

[0053] Embodiment 4

[0054] This embodiment provides a double-lock slider groove type connection device, which includes all the contents of the third embodiment. Compared with the third embodiment, this embodiment improves the structure of the bolt 21.

[0055] In this embodiment, one end surface of the bolt 21 is a plane, and the other end of the bolt 21 forms a spanner nut 211 with a hexagon socket. Figure 5 The bolt 21 abuts against the bottom wall 11 of the slide rail 1 through the plane of its end.

[0056] Therefore, in this embodiment, the bolt 21 is improved so that the double-lock slider groove connection device can be reliably locked with the bottom wall 11 of the slide rail 1, and a hexagonal wrench nut 211 is arranged on the bolt 21, so that the device can conveniently and quickly tighten or loosen the nut 25 by a wrench, thereby ensuring the structural locking force and ensuring accurate position locking.

[0057] Embodiment 5

[0058] This embodiment provides a double-locking slider slot connection device, which includes all the contents of the fourth embodiment. Compared with the fourth embodiment, this embodiment adds a base 3 at the bottom of the slide rail 1. The shape and structure of the base 3 can be customized according to the use and installation requirements.

[0059] In this embodiment, the base 3 may be one or more legs disposed at the bottom of the slide rail 1. Figure 1 The base 3 may also be a connecting plate disposed at the bottom of the slide rail 1. In a specific application, one or more slide rails 1 may be disposed on the base 3 according to the use requirements, and one or more sliding fixing components 2 may be disposed on each slide rail 1.

[0060] In a specific construction engineering installation example, the base 3 and the slide rail 1 can be buried in concrete to ensure that the top notch of the slide rail 1 is flush with the upper surface of the concrete, that is, the track groove 14 and the sliding fixing assembly 2 are exposed to the outside, which is convenient for later use and installation.

[0061] In another specific structural installation example, if the target installation location is a steel structure, the base 3 can be welded to the steel structure, or the base 3 can be removed according to the working conditions and the slide rail 1 can be welded to the steel structure.

[0062] Therefore, the double-lock slider groove connection device provided in the present application can be connected to any steel structure, and the connection methods include but are not limited to welding, bolt 21 connection, etc.

[0063] In specific installation applications, the double-lock slider groove connection device provided in this application can be used to connect and install unit panel curtain walls, steel structure canopies, rails, equipment bases, etc.

[0064] Since the double-lock slider groove connection device provided by the present application not only has the characteristics of reliable mechanical locking, but also has the characteristics of accurate positioning by sliding adjustment, it can be applied in tunnel construction. For example, when the tunnel arch is connected to fix structural members such as steel bars, the double-lock slider groove connection device provided by the present application is buried in the tunnel arch, and the slider 22 can be stably and reliably installed in the slide rail 1. When used later, the slider 22 can be adjusted to the target position, and then the bolt 21 and the locking nut 25 can be tightened with a wrench. The double-lock slider groove connection device forms a reliable connection structure that can be used to install tunnel cables, signal lights, etc. It has a reliable structure, a wide range of uses, and strong practicality.

[0065] The double-lock slider slot connection device provided by the present application achieves the purpose of installation and tightening by applying the reaction force of the mechanical bolt. According to experimental tests, the tensile and shear resistance of double-lock slider slot connection devices of different models and sizes are increased by 30% to 80% compared with transmission connectors.

[0066] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0067] The above is a relatively specific and detailed description of the present application through general description and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
