Description

Technical Field

[0001] This utility model relates to the technical field of excavator instrument panel fixing structure, specifically a multi-threaded column synchronous fixing structure for an instrument panel. Background Technology

[0002] As crucial construction equipment, excavators operate in complex environments, demanding high levels of stability. Therefore, the design and installation of the excavator's instrument panel are paramount. The instrument panel not only houses various display instruments and control switches, but also directly impacts the operator's convenience and the equipment's safety. However, traditional methods of fixing excavator instrument panels often suffer from low installation efficiency and insufficient stability, failing to meet the demands of modern construction for efficient and reliable equipment operation.

[0003] Currently, excavator instrument panels are mostly fixed using bolts and threaded posts at single or a few fixed points. This method requires tightening each bolt individually during installation, which is not only cumbersome and time-consuming but also makes it difficult to ensure even stress distribution at each fixing point, easily leading to loosening and deformation of the instrument panel during long-term use. Furthermore, due to the significant vibrations during excavator operation, single-point fixing makes it even more difficult to guarantee the stability of the instrument panel, increasing the risk of equipment failure. Moreover, if the threaded posts or bolts in existing excavator instrument panel fixing methods strip, the bolts or threaded posts cannot be removed, affecting disassembly and installation. Therefore, a multi-threaded post synchronous fixing structure for the instrument panel is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-threaded column synchronous fixing structure for instrument panels to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-threaded column synchronous fixing structure for an instrument panel, comprising: four first connecting seats and four second connecting seats. The four second connecting seats are respectively connected to the four first connecting seats through an elastic telescopic structure. A sleeve rod is fixedly connected to one side of each of the four second connecting seats. A connecting rod is slidably connected inside the sleeve rod. The end of the connecting rod away from the sleeve rod is fixedly connected to the side of the second connecting seat near the sleeve rod. A positioning hole is provided at the center of the first connecting seats and the second connecting seats. The positioning hole is used to engage the threaded column. Multiple first connecting seats and second connecting seats are synchronously fixed to multiple threaded columns through multiple positioning holes. An elastic thread structure is connected to the inner wall of the positioning hole.

[0006] Preferably, the elastic thread structure includes elastic rubber, which is fixedly connected to the inner wall of the positioning hole, and a threaded plate is fixedly connected to the side of the elastic rubber away from the positioning hole.

[0007] Preferably, the elastic telescopic structure includes a plug-in groove, which is formed inside the first connecting seat. An inner guide rod is slidably connected inside the plug-in groove. One end of the inner guide rod is fixedly connected to the second connecting seat through the plug-in groove. A spring is fixedly connected to the inner sidewall of the plug-in groove. The end of the spring away from the plug-in groove is fixedly connected to the side of the inner guide rod away from the second connecting seat.

[0008] Preferably, the first connecting seat and the second connecting seat are integrally formed with side openings on their exteriors, and the side openings are connected to the positioning holes.

[0009] Preferably, both the first connecting seat and the second connecting seat have a toggle groove on their upper surfaces.

[0010] Preferably, a connecting strap is fixedly connected to one side of the second connecting seat, and a hook and loop fastener is fixedly connected to the side of the connecting strap away from the second connecting seat. A hook and loop fastener is integrally formed on one side of the first connecting seat, and the hook and loop fastener is adhered to the outside of the hook and loop fastener.

[0011] Preferably, the bottom of both the first connector and the second connector is bonded with an adhesive layer, and an anti-sticking film is attached to the outside of the adhesive layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, by employing four first connecting seats and four second connecting seats in conjunction with an elastic telescopic structure, it can quickly adapt to the installation requirements of instrument panels of excavators of different sizes, achieving synchronous fixing of multiple threaded columns. Compared with the traditional single-point or few-point bolt connection method, there is no need to tighten the bolts one by one, greatly simplifying the installation process and saving installation time. At the same time, the elastic telescopic structure ensures that the force on each fixing point is uniform, effectively avoiding problems such as loosening and deformation of the instrument panel during long-term use, improving the overall stability of the equipment, reducing the risk of equipment failure, and providing a strong guarantee for the reliable operation of the excavator.

[0014] In this invention, even if the threaded post or bolt strips during disassembly, the elastic thread structure, in conjunction with the threaded post, allows for easy rotation of the post to the outside. This avoids the problem of bolts or threaded posts being unable to be removed due to stripping, as is common in traditional fixing methods. Furthermore, a side opening and a turning groove are designed to facilitate the separation of the first and second connecting seats from the threaded post, further improving disassembly efficiency.

Detailed Implementation

[0020] 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.

[0021] Please see Figures 1-4 This utility model provides a technical solution:

[0022] A multi-threaded column synchronous fixing structure for an instrument panel includes: four first connecting seats 1 and four second connecting seats 2. The four second connecting seats 2 are connected to the four first connecting seats 1 respectively through an elastic telescopic structure. A sleeve rod 3 is fixedly connected to one side of each of the four second connecting seats 2. A connecting rod 4 is slidably connected inside the sleeve rod 3. The end of the connecting rod 4 away from the sleeve rod 3 is fixedly connected to the side of the second connecting seat 2 near the sleeve rod 3. A positioning hole 5 is provided at the center of the first connecting seats 1 and the second connecting seats 2. The positioning hole 5 is used to engage the threaded column. The multiple first connecting seats 1 and the second connecting seats 2 are synchronously fixed to the multiple threaded columns through the multiple positioning holes 5. The inner wall of the positioning hole 5 is connected with an elastic thread structure.

[0023] Specifically, during use, excavator dashboards are mostly installed using four-hole threaded bolts for positioning. When installing multiple bolts or studs, the user can attach the four first connecting seats 1 and the four second connecting seats 2 to the outside of the holes to be installed, i.e., the dashboard holes. Considering the different sizes of dashboards on different excavators, there are a total of eight parts: four first connecting seats 1 and four second connecting seats 2. These are divided into four groups of two. The first connecting seats 1 and second connecting seats 2 in each group are connected by sleeve rods 3 and connecting rods 4. When using sleeve rods 3 and connecting rods 4, the spacing between the four groups of first connecting seats 1 and second connecting seats 2 can be adjusted. By adjusting the sleeve rods 3, the spacing between the four groups of first connecting seats 1 and second connecting seats 2 can be adjusted. The position inside rod 4 allows for adjustment of the spacing between each pair of first connecting seats 1 and second connecting seats 2, thus adapting to the spacing and installation of instrument panels of different sizes of excavators. After the four sets of first connecting seats 1 and second connecting seats 2 are respectively attached to the four instrument panel mounting holes, the threaded studs are placed into the positioning holes 5 inside the four first connecting seats 1 and second connecting seats 2. After the studs are placed into the positioning holes 5, the telescopic elastic structure between the first connecting seats 1 and second connecting seats 2 can clamp and limit the studs, ensuring the stability of the studs in the absence of external force or connection. After the four studs are installed, the studs are threaded into the instrument panel mounting holes with the four sets of first connecting seats 1 and second connecting seats 2, realizing the synchronous fixing and installation of multiple threaded studs.

[0024] like Figures 1-3 As shown, the elastic thread structure includes an elastic rubber 11, which is fixedly connected to the inner wall of the positioning hole 5, and a threaded plate 10 is fixedly connected to the side of the elastic rubber 11 away from the positioning hole 5.

[0025] Specifically, after connecting the four threaded posts, the first connecting seat 1 and the second connecting seat 2 can be removed from the instrument panel. During the disassembly of the threaded posts, the four first connecting seats 1 and the second connecting seats 2 can be fitted onto the outside of the threaded posts through an elastic telescopic structure, and the threaded plate 10 can be engaged with the threads on the outside of the threaded posts. This allows the threaded posts to be rotated to the outside by the four first connecting seats 1 and the second connecting seats 2 even if the threads on the outside of the threaded posts and the threaded holes on the instrument panel slip, thus forming a complete threaded synchronous disassembly operation. This facilitates disassembly by the staff. Furthermore, with the cooperation of the threaded plate 10 and the elastic rubber 11, it can adapt to different diameters of threaded posts within a certain range, completing the snap-fit ​​and limiting of threaded posts within a certain diameter.

[0026] like Figure 3As shown, the elastic telescopic structure includes a plug groove 8, which is opened inside the first connecting seat 1. An inner guide rod 7 is slidably connected inside the plug groove 8. The inner guide rod 7 is fixedly connected to the second connecting seat 2 at one end of the plug groove 8. A spring 9 is fixedly connected to the inner side wall of the plug groove 8. The end of the spring 9 away from the plug groove 8 is fixedly connected to the side of the inner guide rod 7 away from the second connecting seat 2.

[0027] Specifically, during use, when the operator places the stud into the positioning hole 5, in order to accommodate the outer diameter of different threaded studs to a certain extent, the first connecting seat 1 and the second connecting seat 2, which are attached together, can be pulled outward to separate them. During the process of pulling the first connecting seat 1 and the second connecting seat 2 outward to separate them, the inner guide rod 7 outside the second connecting seat 2 will move inside the insertion groove 8, thereby guiding the separation of the first connecting seat 1 and the second connecting seat 2. After separation, the first connecting seat 1 and the second connecting seat 2 are still connected through the inner guide rod 7 and the insertion groove 8.

[0028] like Figures 1-2 As shown, the first connecting seat 1 and the second connecting seat 2 are integrally formed with a side opening 6, which is connected to the positioning hole 5. The upper surface of the first connecting seat 1 and the second connecting seat 2 are both provided with a toggle groove 12.

[0029] Specifically, when the user needs to separate the first connecting seat 1 and the second connecting seat 2 from the threaded post, the first connecting seat 1 and the second connecting seat 2 can be moved by the moving groove 12 to separate the first connecting seat 1 and the second connecting seat 2. When the first connecting seat 1 and the second connecting seat 2 are separated to a certain degree of opening and closing, the threaded post can pass through the side opening 6, thereby separating the threaded post from the first connecting seat 1 and the second connecting seat 2.

[0030] like Figures 1-4 As shown, a connecting strap 13 is fixedly connected to one side of the second connecting seat 2, and a hook and loop fastener 15 is fixedly connected to the side of the connecting strap 13 away from the second connecting seat 2. A hook and loop fastener 14 is integrally formed on one side of the first connecting seat 1, and the hook and loop fastener 15 is adhered to the outside of the hook and loop fastener 14.

[0031] Specifically, when it is necessary to strengthen the connection between the first connecting seat 1 and the second connecting seat 2, the connecting strap 13 located outside the second connecting seat 2 can drive the hook and loop fastener 15 to adhere to the outside of the hook and loop fastener 14, thereby strengthening the tightness of the connection between the first connecting seat 1 and the second connecting seat 2 through the cooperation of the connecting strap 13 with the hook and loop fastener 15 and the hook and loop fastener 14.

[0032] like Figure 4As shown, the bottom of both the first connecting seat 1 and the second connecting seat 2 is bonded with an adhesive layer 16, and an anti-adhesive film 17 is attached to the outside of the adhesive layer 16.

[0033] Specifically, when multiple first connectors 1 and second connectors 2 are used to connect the instrument panel, in addition to fixing the threaded column, the anti-adhesive film 17 on the outside of the adhesive layer 16 can be peeled off, and multiple sets of first connectors 1 and second connectors 2 can be bonded to the instrument panel through the adhesive layer 16 to form a synchronous fixing structure of adhesive threaded column.

[0034] Based on the above technical solution, the working steps of this solution are summarized as follows: First, adjust the spacing between the four sets of first connecting seats 1 and second connecting seats 2 according to the size of the excavator's instrument panel and the spacing of the mounting holes. The distance between each pair of connecting seats can be flexibly adjusted by the position of the sliding sleeve 3 inside the connecting rod 4 to adapt to the installation requirements of different instrument panels. Next, attach the adjusted four sets of first connecting seats 1 and second connecting seats 2 to the four mounting holes of the instrument panel. At this time, utilizing the elastic telescopic structure between the first connecting seats 1 and second connecting seats 2, including the sliding of the inner guide rod 7 in the insertion groove 8 and the elastic action of the spring 9, the threaded post placed inside the positioning hole 5 can be clamped and limited, ensuring the stability of the post without external force or connection. Then, place the four threaded posts into the positioning holes 5 inside the four first connecting seats 1 and second connecting seats 2 respectively. The elastic threaded structure on the inner wall of the positioning hole 5, including elastic rubber 11 and threaded plate 10, can accommodate studs of different diameters and engage with their external threads, providing additional locking and limiting effects. Subsequently, the studs are threaded into the mounting holes of the instrument panel using four sets of first connecting seats 1 and second connecting seats 2, achieving simultaneous fixing and installation of multiple threaded studs. During installation, the elastic telescopic structure ensures a tight fit between the connecting seats and the studs, improving the stability and reliability of the installation.
