The cable tray can be erected independently in the building or attached to various buildings and pipe gallery brackets. It mainly supports cables and other wire harnesses and has good protection effect and aesthetics.

[0003] In order to facilitate production, transportation, assembly and disassembly, cable trays are often divided into multiple sections and then connected by bolts. This connection method requires the installation of multiple sets of bolts to fix the two cable trays together. Although this method is simple to operate, it requires a lot of work.

[0004] In order to facilitate the installation of the cable tray, the prior art also uses a snap-on connection. However, this method requires that the ends of the cable tray are in a tightly fitted state. When the fit of the ends of the cable tray is poor, the snap-on structure is easily misplaced and fails to perform the corresponding connection action, resulting in poor stability of the cable tray after installation.

[0009] As a further solution of the present invention: the rotating shaft of the follower passes through the cable bridge body and is connected to an operating rod; The limiting position includes two groups of limiting parts arranged on the follower, the two groups of limiting parts are connected by two groups of intersecting inclined surfaces, and a protrusion is arranged at the intersection position of the two groups of inclined surfaces.

[0010] As a further solution of the present invention: the oblique traction assembly comprises a connecting plate mounted on the cable bridge body, the connecting plate is provided with an inclined groove, a groove wheel is rotatably mounted in the inclined groove, and one end of the groove wheel is coaxially rotatably connected with the first convex shaft; The guide groove includes a straight groove arranged along the radial direction of the follower and an arc groove connected with the straight groove, and the center of the arc groove is concentric with the rotation center of the follower.

[0011] As a further solution of the present invention: the elastic tensioning structure comprises a sliding connection piece installed on the cable bridge body, a connecting rod is slidably installed on the sliding connection piece, one end of the connecting rod is provided with an abutment piece, and the other end is slidably connected to a transverse axis provided on the sliding connection piece; A second spring is sleeved on the transverse axis, one end of the second spring is connected to the end of the transverse axis, and the other end of the second spring is connected to the end of the connecting rod; The elastic tensioning structure further comprises a second protruding shaft arranged at the other side of the groove wheel, and when the groove wheel moves downward along the inclined groove, the second protruding shaft can abut against the abutment member.

[0012] As a further solution of the present invention: the locking assembly comprises an incomplete toothed ring coaxially connected to the follower, and the incomplete toothed ring is adapted to a rack plate slidably mounted on the cable bridge body; The locking assembly also includes a rotational locking structure disposed between two adjacent groups of the cable bridge bodies, and the rotational locking structure is connected to the rack plate.

In addition, since the position stability of the follower is provided by the first spring, the position of the follower has a certain elastic correction effect, thereby ensuring that when the cable bridge body is subjected to high-frequency vibration, the two groups of cable bridge bodies can still be locked with the cooperation of the locking part and the locking plate.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0030] See also Figure 1 to Figure 10 In an embodiment of the present invention, a flip-open, close and lockable tray cable bridge is formed by a plurality of cable bridge bodies 1, on which a cover plate 2 is detachably mounted, and includes: a follower 6, an oblique pulling assembly, an elastic tensioning structure and a locking assembly.

[0031] One end of the cable bridge body 1 is provided with a plurality of limit grooves 4, and the other end is provided with a plurality of limit members 3, and the limit members 3 are adapted to the limit grooves 4; Two groups of guide surfaces are symmetrically arranged at the opening of the limiting groove 4 , and the guide surfaces can guide the limiting member 3 to enter the limiting groove 4 .

[0032] When assembling the cable bridge body 1, first fix the first group of cable bridge bodies 1. After the cable bridge body 1 is fixed, align the limit members 3 on the other group of cable bridge bodies 1 with the limit grooves 4 on the fixed cable bridge body 1 and insert them, so that the two groups of cable bridge bodies 1 can be aligned. Among them, since two groups of guide surfaces are provided at the opening of the limit groove 4, specifically, the two groups of guide surfaces are in an "eight" shaped structure, which makes it easier for the limit member 3 to enter the limit groove 4, that is, it has a certain "fool-proof" effect, which effectively reduces the difficulty of assembly and improves assembly efficiency.

[0033] See also Figure 4 , Figure 5 , Figure 7~Figure 9 , the follower 6 is installed on the cable bridge body 1, and a limit position is provided on the follower 6, and the limit position is connected to the energy storage structure provided on the cable bridge body 1; The energy storage structure comprises a hysteresis sleeve 9 mounted on the cable bridge body 1, a telescopic shaft 8 is slidably mounted in the hysteresis sleeve 9, an abutment wheel 7 that rolls with the limit position is rotatably mounted on one end of the telescopic shaft 8, and a limit ring 801 is provided on the telescopic shaft 8; The telescopic shaft 8 is also sleeved with a first spring 10, one end of the first spring 10 is connected to the limit ring 801, and the other end is connected to the inner wall of the hysteresis sleeve 9; The rotating shaft of the follower 6 passes through the cable bridge body 1 and is connected to the operating rod 5; The limiting position includes two groups of limiting parts 601 arranged on the follower 6. The two groups of limiting parts 601 are connected by two groups of intersecting inclined surfaces 602. A protrusion 603 is arranged at the intersection of the two groups of inclined surfaces 602.

[0034] In the initial state, the first spring 10 is in a compressed state. At this time, the first spring 10 can enable the abutment wheel 7 to act on one set of limiting parts 601 through the telescopic shaft 8, and the extension line of the telescopic shaft 8 passes through the rotation center of the follower 6, so that in this state, the follower 6 has a certain limiting effect, thereby improving the stability of the follower 6 in the initial state.

[0035] When the ends of the two groups of cable bridge bodies 1 to be connected are fitted together, the control operating rod 5 is controlled to deflect upward, which can drive the follower 6 connected thereto to deflect, and make the abutment wheel 7 separate from the limiting portion 601 and move along one group of inclined surfaces 602 toward the protrusion 603. During this process, the first spring 10 is further compressed, so that it can store potential energy, and as the follower 6 deflects, when the abutment wheel 7 moves over the protrusion 603, the first spring 10 can actively release elastic potential energy, so that the abutment wheel 7 can move along another group of inclined surfaces 602 to another group of limiting portions 601. During this process, the follower 6 can actively rotate, and when the abutment wheel 7 enters another group of limiting portions 601, the follower 6 can be limited again.

[0036] Furthermore, when the follower 6 moves, the two groups of cable bridge bodies 1 to be connected can be assembled through the oblique pulling assembly, the elastic tensioning structure and the locking assembly, and when the abutment wheel 7 is in the two groups of limiting parts 601, the follower 6 can maintain a stable deflection state, making it easier to dock the two groups of cable bridge bodies 1 before assembly, and after the two groups of cable bridge bodies 1 are assembled, the connection performance of the two parts is better.

[0037] See also Figure 4~Figure 5 , Figure 8~Figure 9 The oblique pulling assembly is arranged on the cable bridge body 1, and a first convex shaft 13 is arranged on the oblique pulling assembly. The first convex shaft 13 cooperates with a guide groove arranged on the follower 6, and can drive the first convex shaft 13 to move obliquely downward when the follower 6 rotates; The oblique traction assembly comprises a connecting plate 11 mounted on the cable bridge body 1, the connecting plate 11 is provided with an inclined groove 1101, a groove wheel 12 is rotatably mounted in the inclined groove 1101, and one end of the groove wheel 12 is coaxially rotatably connected with the first convex shaft 13; The guide groove includes a straight groove 604 arranged along the radial direction of the follower 6 and an arc groove 605 connected to the straight groove 604 . The center of the arc groove 605 is concentric with the rotation center of the follower 6 .

[0038] In the initial state, the straight groove 604 is in a horizontal state. At this time, the first convex shaft 13 is at one end of the straight groove 604 close to the rotation center of the follower 6, and the groove wheel 12 is at the upper end of the inclined groove 1101. When the follower 6 rotates, the straight groove 604 can deflect downward, and in cooperation with the first convex shaft 13, the groove wheel 12 moves along the length direction of the inclined groove 1101. When it abuts against the elastic tensioning structure, it can pull the elastic tensioning structure to move, so that the two groups of cable bridge bodies 1 can fit tightly together.

[0039] When the abutment wheel 7 moves past the protrusion 603 and the follower 6 actively rotates, the first cam 13 moves to the end of the straight groove 604 and moves along the arc groove 605. At this time, the first cam 13 and the groove wheel 12 are in a locked state, so that when the first spring 10 releases its elastic potential energy, the elastic tensioning structure produces a smaller reverse force on the groove wheel 12, thereby preventing the first spring 10 from being unable to actively release its elastic potential energy due to the pulling of the elastic tensioning structure.

[0040] See also Figure 4 , Figure 5 , Fig. 9 The elastic tensioning structure is connected to the oblique pulling assembly, and the elastic tensioning structure can make the ends of two adjacent groups of the cable bridge bodies 1 fit together when the first convex shaft 13 moves obliquely downward; The elastic tensioning structure comprises a sliding connection member 17 mounted on the cable bridge body 1, a connecting rod 16 is slidably mounted on the sliding connection member 17, one end of the connecting rod 16 is provided with an abutment member 15, and the other end is slidably connected to a transverse shaft 18 provided on the sliding connection member 17; A second spring 19 is sleeved on the transverse shaft 18, one end of the second spring 19 is connected to the end of the transverse shaft 18, and the other end is connected to the end of the connecting rod 16; The elastic tensioning structure further includes a second protruding shaft 14 disposed on the other side of the groove wheel 12. When the groove wheel 12 moves downward along the inclined groove 1101, the second protruding shaft 14 can abut against the abutment member 15. In the initial state, the second spring 19 is in a natural state, and in the initial state, the distance between the abutment 15 and the end of the cable bridge body 1 is smaller than the length of the limiting member 3, so that when the limiting member 3 is inserted into the limiting groove 4 (not reaching the end of the limiting groove 4), the abutment 15 can move relative to the second cam 14, and after the limiting member 3 moves to the end of the limiting groove 4, the abutment 15 moves to the side of the second cam 14 toward the rotating shaft of the follower 6.

[0041] It should also be noted that, in the initial state, the upper end of the abutment member 15 and the second protruding shaft 14 are in a misaligned state.

[0042] When the groove wheel 12 moves downwardly along the length direction of the inclined groove 1101 with the cooperation of the first protruding shaft 13 and the straight groove 604, the second protruding shaft 14 can abut against the abutment member 15, and after abutment, drive the abutment member 15 to move away from the sliding connection member 17. At this time, the second spring 19 can be compressed to make the ends of the two groups of cable bridge bodies 1 fit more closely.

[0043] Based on the above arrangement, when driving the operating rod 5 to flip, the first protrusion 13 can cooperate with the straight groove 604 to make the groove wheel 12 move along the inclined groove 1101, and when abutting with the abutment 15, it pulls the abutment 15 to move, thereby making the fit between the ends of the two groups of cable bridge bodies 1 tighter, and when the first protrusion 13 moves into the arc groove 605, the position of the first protrusion 13 can also be locked, so that the two groups of cable bridge bodies 1 maintain a high-tight abutment state, so as to facilitate the action of the locking assembly, and achieve a stable locking state between the two groups of cable bridge bodies 1.

[0044] See also Figure 4~Figure 6 , Fig.10 The locking assembly connects two adjacent groups of the cable bridge bodies 1, and the locking assembly can lock the two groups of adjacent cable bridge bodies 1 when the ends thereof fit together; The locking assembly includes an incomplete toothed ring 20 coaxially connected to the follower 6, and the incomplete toothed ring 20 is adapted to a rack plate 21 slidably mounted on the cable bridge body 1; The locking assembly also includes a rotary locking structure arranged between two adjacent groups of the cable bridge bodies 1, the rotary locking structure is connected to the rack plate 21, and the rotary locking structure includes a rotary sleeve 24 rotatably mounted on the cable bridge body 1 and a driving shaft 22 connected to the rack plate 21, the rotary sleeve 24 is provided with a horizontal groove 2401 and a spiral groove 2402 along its length direction, and the embedded shaft 23 installed on the driving shaft 22 can slide in the horizontal groove 2401 and the spiral groove 2402, specifically, when the embedded shaft 23 moves in the spiral groove 2402, the rotary sleeve 24 can be rotated 90°; The rotary locking structure includes a connection kit arranged at the end of the rotating sleeve 24, and the connection kit includes a locking plate 26 installed on the cable bridge body 1 and a locking portion 25 connected to the end of the rotating sleeve 24, and the locking plate 26 is provided with a hollow portion 2601 that allows the locking portion 25 to pass through.

[0045] When the ends of the two groups of cable bridge bodies 1 are in a tightly fitted state, the locking portion 25 can penetrate the hollow portion 2601, and when the operating rod 5 is deflected to drive the follower 6 to move, the incomplete toothed ring 20 is in a state of separation from the rack plate 21, and when the follower 6 rotates until the abutment wheel 7 cooperates with the inclined surface 602 and actively deflects, the incomplete toothed ring 20 can engage with the rack plate 21. At this time, the rack plate 21 moves away from the follower 6 and drives the drive shaft 22 to move toward the inside of the rotating sleeve 24. During this process, the engaging shaft 23 can move along the horizontal groove 2401 and the spiral groove 2402 in sequence, and when the engaging shaft 23 moves into the spiral groove 2402, it can drive the rotating sleeve 24 to rotate and rotate the locking portion 25, so that the locking portion 25 is misaligned with the hollow portion 2601 and abuts against it. At this time, a stable lock between the two groups of cable bridges can be achieved.

[0046] It should be noted that the rack plate 21, the drive shaft 22 and the cable bridge body 1 are in a sliding connection state, and the two will not rotate, so that the drive shaft 22 has a stable axial state. In this way, when the engaging shaft 23 is in the horizontal groove 2401, the rotating sleeve 24 can be in an axial locking state, thereby improving the stability of the locking portion 25 in the initial state, so as to ensure that when the ends of the two sets of cable bridge bodies 1 are fitted together, the locking portion 25 can pass through the hollow portion 2601.

[0047] Through the above-mentioned arrangement, after the ends of the two groups of cable bridge bodies 1 are fitted together, the locking portion 25 can be misaligned with the hollow portion 2601 by rotating, thereby realizing a stable connection between the two groups of cable bridge bodies 1, and improving the stability of the locking portion 25 when cooperating with the locking plate 26. In addition, since the position stability of the follower 6 is provided by the first spring 10, the position of the follower 6 has a certain elastic correction effect, thereby ensuring that when the cable bridge body 1 is subjected to high-frequency vibration, the two groups of cable bridge bodies 1 can still be locked with the cooperation of the locking portion 25 and the locking plate 26.

[0048] As an embodiment of the present invention, a method for assembling the flip-open-close-lock tray cable tray as described above is also proposed, comprising the following steps: Step 1: abut the ends of two sets of cable bridge bodies 1 to be connected; Step 2: The operating rod 5 drives the follower 6 to rotate, and the guide groove cooperates with the tilting pulling assembly to make the first convex shaft 13 move downward in an inclined manner; Step 3: When the first protruding shaft 13 moves downward in an inclined manner, the elastic tensioning structure is pulled, thereby increasing the abutment force between the ends of the two sets of cable bridge bodies 1; Step 4: The energy storage structure cooperates with the limiting position to actively drive the follower 6 to rotate, thereby actuating the locking assembly to complete the connection between the two adjacent groups of cable bridge bodies 1.

[0049] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and range of equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0050] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

An assembly method of a flip-open-close-lock tray cable tray as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Abut the ends of the two sets of cable bridge bodies to be connected; Step 2: The follower is driven to rotate by the operating rod, and the guide groove cooperates with the tilting pulling assembly to make the first convex shaft tilt and move downward; Step 3: When the first convex shaft moves downwardly, the elastic tensioning structure is pulled, thereby increasing the abutment force between the ends of the two sets of cable bridge bodies; Step 4: The energy storage structure cooperates with the limiting position to actively drive the follower to rotate, thereby actuating the locking assembly to complete the connection between the two adjacent groups of cable bridge bodies.
