Description

Technical Field

[0001] This utility model relates to the field of rail transit equipment technology, and in particular to a quick-install bracket for a contact rail protective cover. Background Technology

[0002] In urban rail transit systems, such as subways and light rails, the contact rail (or third rail) is a critical component that provides power to the train. Because its surface carries high-voltage direct current, protective covers are typically installed above or to the side of the contact rail to ensure personnel safety and prevent debris intrusion. These protective covers need to be secured to the ground or structure beside the track using numerous mounting brackets.

[0003] Currently, existing mounting brackets are generally fixed using bolt connections or clamps. This traditional installation method first requires installers to manually support the bracket and protective cover to the predetermined position and precisely align the holes, then tighten the fixing bolts one by one using wrenches and other tools. This process is not only cumbersome but also time-consuming, resulting in low overall construction efficiency. More importantly, during manual support and alignment, the bracket or protective cover is prone to displacement due to shaking, which not only affects the final installation accuracy and stability but may also pose safety hazards due to inaccurate positioning. Therefore, the existing installation method suffers from low installation efficiency, high labor intensity, and difficulty in guaranteeing installation accuracy. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quick-installation bracket for contact rail protective covers, aiming to improve the problems of cumbersome installation steps, reliance on manual support for alignment, low fixation reliability, and low installation efficiency of existing contact rail protective cover installation brackets. This utility model aims to provide a quick-installation bracket for contact rail protective covers with an improved structure that can effectively solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-install bracket for a contact rail protective cover, comprising: an arc-shaped bracket, a fixing block, a connecting component, and a fixing component.

[0006] The connecting assembly includes a tapered rod, a top block, and a first spring; the fixing assembly includes an openable first fixing claw and a second fixing claw, a fixing tongue, and a second spring.

[0007] Furthermore, the connecting assembly and the fixing block are combined in the following manner: the tapered rod is adapted to press down the top block after being pressed and rotated, and is locked between the top block and the outer shell under the rebound force of the first spring, so as to lock the arc-shaped bracket above the fixing block; the components of the fixing assembly are combined in the following manner: the fixing tongue is adapted to squeeze and open the first fixing claw and the second fixing claw when driven by the protective cover, and after passing a predetermined position, the first fixing claw and the second fixing claw are driven by the second spring to reset to clamp the fixing tongue.

[0008] Preferably, the connecting assembly further includes a connecting block and a connecting post for transmitting pressing force to the tapered rod; the connecting assembly further includes a housing and a cover therethrough, wherein the first spring and the top block are housed within the housing.

[0009] Preferably, the fixing component further includes a fixing plate, which is fixed to the arc-shaped bracket by screws.

[0010] Preferably, the fixing component further includes a fixing body, to which the first fixing claw and the second fixing claw are connected.

[0011] Preferably, the two ends of the second spring abut against the fixing body and the fixing plate, respectively.

[0012] Preferably, the fixing component further includes a connecting seat and a fixing seat, the connecting seat being adapted to connect with the protective cover and used to move the fixing seat.

[0013] Preferably, the fixing tongue and the fixing seat are connected by a connecting rod.

[0019] 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.

[0020] Please refer to Figures 1 to 4 This utility model provides a quick-install bracket for a contact rail protective cover, which aims to solve the problems of complex installation structure, cumbersome installation steps, and insufficient fixing reliability in the prior art.

[0021] like Figure 1 As shown, the installation system of the quick-install bracket for the contact rail protective cover includes a fixing block 301 set on the ground 1 and a bracket body that cooperates with the fixing block 301. The bracket body includes an arc-shaped bracket 4, and a connecting component 3 and a fixing component 5 respectively set at both ends of the arc-shaped bracket 4. The connecting component 3 is used to connect the bracket body to the ground 1, and the fixing component 5 is used to quickly clamp and fix the protective cover 2. Through the synergistic effect of the connecting component 3 and the fixing component 5, the entire process from bracket installation to fixing of the protective cover 2 is achieved quickly.

[0022] Please refer to the following carefully. Figure 3The connecting assembly 3 includes a housing 307, a top block 305 housed inside the housing 307, and a first spring 308. The first spring 308 is disposed between the inner bottom of the housing 307 and the top block 305, providing continuous elastic support to the top block 305. The connecting assembly 3 also includes a cover 306, which is fixed to the top opening of the housing 307. A tapered rod 304 rotatably passes through the cover 306. The upper end of the tapered rod 304 is sequentially connected to a connecting post 303 and a connecting block 302, while its lower end can press down on the top block 305. The tapered rod 304 has a tapered block at its bottom, and the top block 305 has an internal guide groove. When the connecting block 302 is pressed, the tapered rod 304 moves downward under the action of force. By manually rotating, the tapered block of the tapered rod 304 is rotated to a specified angle, and the top block 305 is pressed down. When the first spring 308 is compressed to the bottom, the pressure is released. The rebound force of the first spring 308 will push the top block 305 and the tapered rod 304 to move in opposite directions until the tapered block is stuck at a specific position on the inner wall of the top block 305, thereby forming a stable and reliable limit lock.

[0023] At the same time, please refer to Figure 4 The fixing assembly 5 includes a fixing plate 501 fixedly connected to the arc-shaped bracket 4 by screws 502. A fixing body 504 is fixedly mounted on the fixing plate 501 by a second spring 503. The fixing body 504 is provided with a first fixing claw 505 and a second fixing claw 506 that can cooperate to open and close. The second spring 503 provides a return force to the fixing body 504 towards the clamping position. The fixing assembly 5 also includes a fixing tongue 507, which is connected to a fixing seat 509 via a connecting rod 508. The fixing seat 509 is fixedly connected to a connecting seat 510 suitable for connection to the end of the protective cover 2. When the cover 2 is pushed toward the fixing component 5, the connecting seat 510 will drive the fixing seat 509 and the fixing tongue 507 to move synchronously. The front end of the fixing tongue 507 is wedge-shaped. When it enters between the first fixing claw 505 and the second fixing claw 506, it will force the two fixing claws to overcome the elastic force of the second spring 503 and open to both sides. After the fixing tongue 507 has completely entered and passed the widest part of the first fixing claw 505 and the second fixing claw 506, the elastic force of the second spring 503 will drive the fixing body 504 together with the first fixing claw 505 and the second fixing claw 506 to quickly return to its original position, thereby achieving a firm clamping and fixing of the fixing tongue 507 from both sides.

[0024] Working principle: When installing the bracket, first align the connecting component 3 at the bottom of the arc bracket 4 with the fixing block 301 on the ground 1, and press down on the connecting block 302. The pressing force is transmitted to the tapered rod 304 through the connecting column 303, causing the tapered rod 304 to move downward and press down on the top block 305, thereby pushing the top block 305 to compress the first spring 308 below it. During this process, manually rotate the tapered rod 304 to a predetermined angle. When the pressing force is released, the rebound force of the first spring 308 pushes the top block 305 and the tapered rod 304 to move in opposite directions. Due to the cooperation between the tapered block on the tapered rod 304 and the inner groove of the top block 305, this reverse movement will make the tapered rod 304 firmly locked in the top block 305, thereby realizing a quick and stable locking between the arc bracket 4 and the fixing block 301. When fixing the protective cover 2, the protective cover 2 is pushed horizontally towards the fixing component 5. The connecting seat 510 connected to the protective cover 2 drives the fixing seat 509 and the fixing tongue 507 connected to it via the connecting rod 508 to move synchronously. The wedge-shaped front end of the fixing tongue 507 enters and spreads the first fixing claw 505 and the second fixing claw 506. This spreading action causes the fixing body 504 connected to the fixing claw to move against the elastic force of the second spring 503. When the fixing tongue 507 is fully inserted between the first fixing claw 505 and the second fixing claw 506, the elastic energy stored in the second spring 503 is released instantly, driving the fixing body 504 to reset, thereby driving the first fixing claw 505 and the second fixing claw 506 to return to their original positions and tightly clamp the fixing tongue 507, thus completing the automatic clamping and fixing of the protective cover 2. Through the downward rotation locking structure of the connecting component 3 and the push-in self-locking clamping structure of the fixing component 5, this utility model effectively solves the problem of cumbersome installation steps and inaccurate positioning caused by reliance on manual support in the prior art, and significantly improves the installation efficiency and reliability.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
