Description

Technical Field

[0001] This utility model relates to the field of slotted support technology, and in particular to a stable structure for placing large slotted supports. Background Technology

[0002] Cable trays are the most common type of trough-type support. They consist of mounting slots inside the support, where cables are placed. The support is then fixed to a wall, roof, or ground. This design allows cables to be placed in the mounting slots, preventing them from being directly exposed to the external environment and reducing interference from external factors, thus providing reliable protection for the cables.

[0003] During the installation of trough-type cable trays, the trough-type brackets need to be fixed to the wall, roof, or ground using fasteners. The most common method is to fix the trough-type cable trays to the roof, which can utilize the top space, reduce the encroachment on the effective indoor space, and improve the space utilization rate.

[0004] Chinese utility model patent application number CN202320741843.1 describes a reinforced cable tray. Through the design of an adjusting rod, positioning piece, insertion hole, and clearance groove, when a separate cable tray consisting of a base plate and movable side plates is placed on a supporting horizontal plate, the operator can pre-rotate the adjusting rod to position the positioning piece corresponding to the clearance groove. After the base plate is placed on the top surface of the supporting horizontal plate, the adjusting rod and positioning piece can pass through the insertion hole and clearance groove respectively. Then, the operator rotates the adjusting rod to rotate the positioning piece 90 degrees to fit against the bottom surface of the supporting horizontal plate, thus misaligning the positioning piece with the clearance groove. The positioning plate, in conjunction with the adjusting rod, can effectively position and stabilize the base plate on the load-bearing horizontal plate, enhancing the base plate's stability on the load-bearing horizontal plate and preventing it from moving due to external interference. However, in the aforementioned cable tray, the positions of the adjusting rod and positioning plate are fixed and cannot be moved along the length of the base plate. As a result, when the hanging plate and load-bearing horizontal plate are pre-installed and dimensional errors occur, the adjusting rod cannot be accurately aligned and inserted into the clearance groove when the base plate is placed on the load-bearing horizontal plate. In this case, it is necessary to reinstall and adjust the positions of the hanging plate and load-bearing horizontal plate to ensure that the base plate placement and installation work can continue, reducing the practicality of the cable tray. Utility Model Content

[0005] The purpose of this application is to provide a stable structure for placing large slotted supports, in order to solve the problem mentioned in the background art that the positions of the adjusting rod and positioning plate are fixed and cannot be moved along the length of the base plate. This makes it impossible for the adjusting rod to be accurately aligned and inserted into the clearance slot when the base plate is placed on the support plate after the hanging plate and the bearing horizontal plate are pre-installed and there are dimensional errors.

[0006] To achieve the above objectives, this application provides the following technical solution: a stable structure for placing a large trough-type support, comprising a trough-type support and a placement base plate. The trough-type support is placed on top of the placement base plate. Two elongated limiting through slots are symmetrically opened on the inner bottom wall of the trough-type support. Two through holes are symmetrically opened on the bottom of the placement base plate. The two limiting through slots are respectively located above the two through holes and are interconnected. The application also includes two symmetrically distributed stabilizing components. The two stabilizing components are fixedly connected together by the two limiting through slots. The stabilizing components can slide along the length direction of the limiting through slots.

[0007] Preferably, the stabilizing component includes two upper fixing blocks symmetrically placed within the slot of the slotted bracket. Two limiting rods are symmetrically fixedly connected to the center of the bottom of each upper fixing block. The bottom ends of the two limiting rods pass through two limiting slots and two through holes, respectively, and are fixedly connected to a lower fixing block. The limiting rods are slidably connected within the limiting slots. Multiple clamping rods are arranged in a ring on each upper fixing block. The stabilizing component also includes a driving unit, which drives the clamping rods to swing, clamping or releasing the slotted bracket. This configuration allows the slotted bracket and the placement base plate to be clamped by the driving unit driving the multiple clamping rods to swing, thus ensuring the slotted bracket is securely placed on the placement base plate, preventing displacement and slippage, and improving the stability of the slotted bracket.

[0008] Preferably, the driving unit includes a cavity formed at the top of the upper fixed block. Multiple circular holes are annularly formed on the inner wall of the cavity, with the other ends of each hole penetrating the outer wall of the upper fixed block. The number of circular holes corresponds to the number of clamping rods. A rod is movably inserted into each of the circular holes. The clamping rods are rotatably connected to rectangular grooves at the bottom of the rods via shafts and torsion springs. A fixing ring is fixedly fitted onto the outer circumference of each rod. A first elastic element is fixedly connected between the side of the fixing ring and the inner wall of the cavity. A frustum-shaped push block is provided inside the cavity. The adjacent ends of the rods abut against the outer surface of the push block. A second elastic element is fixedly connected between the bottom of the push block and the bottom wall of the cavity. A straight... The bottom of the straight hole passes through the limiting rod and the lower fixing block. A straight rod is fixedly connected to the bottom of the push block. The bottom end of the straight rod extends to the lower side of the lower fixing block and is fixedly connected to a pull plate. The bottom of the lower fixing block has a first slot. The pull plate can be interactively inserted into the first slot. The straight rod passes through the first slot. The advantage of this design is that the operator only needs to rotate the pull plate to align it with the first slot and then release it. At this time, under the elastic force of the second elastic element, the push block will move upward and push the multiple insert rods in opposite directions. At this time, under the elastic force of the torsion spring, the multiple clamping rods will swing downward until they are pressed tightly against the inner bottom wall of the slotted bracket. In this way, the slotted bracket and the placement base plate can be easily clamped together, simplifying the clamping operation and improving the practicality of the stable structure.

[0009] Preferably, the driving unit further includes a second slot formed at the bottom of the lower fixing block. The depth of the second slot is less than that of the first slot. The center lines of the second slot and the first slot coincide and the included angle between them is greater than zero degrees. The straight rod passes through the second slot. The advantage of this arrangement is that by inserting the pull plate into the second slot, and because the depth of the second slot is less than that of the first slot, the distance that the push block pushes the rod is smaller. This allows the clamping rod to fit against the inner bottom wall of the slotted bracket without putting pressure on it. In this way, the slotted bracket can be limited while moving along the length of the base plate. This makes it easier for workers to adjust the position of the slotted bracket during installation. Furthermore, the slotted bracket will not swing up and down during movement, thus reducing the difficulty of adjusting the position of the slotted bracket and further improving the practicality of the stable structure.

[0010] Preferably, a roller is rotatably connected to the bottom of the clamping rod at the end away from the upper fixing block. The roller has an angle with the vertical plane, and the outer edge of the roller has a semi-circular cross-section. The advantage of this setting is that when the elastic force of the second elastic element decreases and the downward swing angle of the clamping rod decreases, the outer edge of the roller can still effectively abut against the inner bottom wall of the slotted bracket, ensuring the stability of the slotted bracket when it is placed on top of the base plate.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] 1. In this utility model, by setting two elongated limiting slots, the two stabilizing components can slide along the length direction of the two limiting slots. In this way, when the stabilizing components do not completely clamp the slotted bracket and the placement base plate, the slotted bracket can move along the length direction of the placement base plate, thereby allowing the position of the slotted bracket to be adjusted within a certain range. This ensures that even if there are errors in the spacing between the placement base plates, the connection and installation of the slotted bracket can be carried out smoothly, improving the reliability and practicality of the stabilizing structure.

[0013] 2. In this utility model, by setting a first through slot and a second through slot, when the pull plate is inserted into the first through slot or the second through slot, the clamping rod can be tightly pressed against or attached to the inner bottom wall of the slot bracket. This not only firmly clamps the slot bracket and the placement base plate to improve the stability of the slot bracket, but also limits the position of the slot bracket, ensuring that it will not swing up and down when the worker pushes the slot bracket to move along the length direction. This reduces the difficulty of adjusting the position of the slot bracket during installation and further improves the practicality of the stable structure. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Example 1

[0024] Please refer to Figure 1-6 The large trough-type support structure shown includes a trough-type support 1 and a base plate 2. The top of the trough-type support 1 is connected to a trough cover 11. The top of the base plate 2 is symmetrically and fixedly connected to two angle steel rods 5. The two angle steel rods 5 are fixedly connected to the roof. The trough-type support 1 is placed on top of the base plate 2. Two elongated limiting through grooves 3 are symmetrically opened on the inner bottom wall of the trough-type support. The bottom of the base plate 2 is symmetrically opened to two through holes. The two limiting through grooves 3 are located above the two through holes and are interconnected. It also includes two symmetrically distributed stabilizing components 4. The two stabilizing components 4 are fixedly connected to the trough-type support 1 and the base plate 2 through the two limiting through grooves 3. The stabilizing components 4 can slide along the length of the limiting through grooves 3.

[0025] refer to Figure 1-4 The stabilizing component 4 includes two upper fixing blocks 41 symmetrically placed in the groove of the slotted bracket 1. Two limiting rods 42 are symmetrically fixedly connected to the bottom center of the two upper fixing blocks 41. The bottom ends of the two limiting rods 42 pass through two limiting through slots 3 and two through holes respectively and are fixedly connected to a lower fixing block 43. The limiting rods 42 are slidably connected in the limiting through slots 3. Multiple clamping rods 44 are provided in a ring on the upper fixing blocks 41. The stabilizing component 4 also includes a driving unit 45, which is used to drive the clamping rods 44 to swing to clamp the slotted bracket 1 or to release the slotted bracket 1.

[0026] Specifically, the drive unit 45 drives multiple clamping rods 44 to swing, which clamps the slotted bracket 1 and the placement base plate 2, so that the slotted bracket 1 can be stably placed on the placement base plate 2, preventing the slotted bracket 1 from shifting or sliding, and improving the stability of the slotted bracket 1.

[0027] Example 2

[0028] According to Example 1, please refer to Figure 4-6 The drive unit 45 includes a cavity 451 formed on the top of the upper fixed block 41. Multiple circular holes 452 are annularly formed on the inner wall of the cavity 451. The other ends of the multiple circular holes 452 penetrate the outer wall of the upper fixed block 41. The number of the multiple circular holes 452 is equal to the number of multiple clamping rods 44 and corresponds one-to-one. Insertion rods 453 are movably inserted into each of the multiple circular holes 452. The multiple clamping rods 44 are rotatably connected to the rectangular grooves at the bottom of the multiple insertion rods 453 via rotating shafts and torsion springs. A fixing ring 454 is fixedly sleeved on the outer circumference of the insertion rod 453. A first elastic element 455 is fixedly connected between the side of the fixing ring 454 and the inner wall of the cavity 451. The cavity 451 is provided with a frustum-shaped push block 456. The ends of the insert rods 453 that are close to each other abut against the outer surface of the push block 456. A second elastic element is fixedly connected between the bottom of the push block 456 and the inner bottom wall of the cavity 451. A straight hole is opened on the inner bottom wall of the cavity 451. The bottom end of the straight hole passes through the limiting rod 42 and the lower fixing block 43. A straight rod 457 is fixedly connected to the bottom of the push block 456. The bottom end of the straight rod 457 extends to the lower side of the lower fixing block 43 and is fixedly connected to the pull plate 458. A first slot 459 is opened at the bottom of the lower fixing block 43. The pull plate 458 can be inserted into the first slot 459. The straight rod 457 passes through the first slot 459.

[0029] Specifically, the operator only needs to rotate the pull plate 458 to align it with the first slot 459 and then release it. At this time, under the elastic force of the second elastic element, the push block 456 will move upward and push the multiple insert rods 453 in opposite directions. At this time, under the elastic force of the torsion spring, the multiple clamping rods 44 will swing downward until they are pressed tightly against the inner bottom wall of the slotted bracket 1. In this way, the slotted bracket 1 and the placement base plate 2 can be easily clamped together, simplifying the clamping operation and improving the practicality of the stable structure.

[0030] Example 3

[0031] Please refer to Example 1 or 2. Figure 4-6 The drive unit 45 also includes a second slot 4510 opened at the bottom of the lower fixing block 43. The depth of the second slot 4510 is less than that of the first slot 459. The center lines of the second slot 4510 and the first slot 459 coincide and the included angle between them is greater than zero degrees. The straight rod 457 passes through the second slot 4510.

[0032] Specifically, by inserting the pull plate 458 into the second slot 4510, and since the depth of the second slot 4510 is less than that of the first slot 459, the push block 456 pushes the insertion rod 453 a smaller distance, so that the clamping rod 44 fits against the inner bottom wall of the slot bracket 1 without putting pressure on the inner bottom wall of the slot bracket 1. In this way, the slot bracket 1 can be limited while not affecting its movement along the length of the placement base plate 2, which makes it easier for the staff to adjust the position of the slot bracket 1 during installation. Furthermore, the slot bracket 1 will not swing up and down during the movement, thereby reducing the difficulty of adjusting the position of the slot bracket 1 and further improving the practicality of the stable structure.

[0033] refer to Figure 4 and Figure 5 A roller 46 is rotatably connected to the bottom of the clamping rod 44 away from the upper fixed block 41. The roller 46 has an angle with the vertical plane, and the outer edge cross-section of the roller 46 is semi-circular.

[0034] Specifically, this ensures that when the elastic force of the second elastic element decreases and the downward swing angle of the clamping rod 44 decreases, the outer edge of the roller 46 can still effectively abut against the inner bottom wall of the slotted bracket 1, thus guaranteeing the stability of the slotted bracket 1 when it is placed on top of the base plate 2.

[0035] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
