Description

Technical Field

[0001] The invention relates to the technical field of cable installation, in particular to a combined cable installation bracket. Background Art

[0002] The combined cable tray is a new type of cable bracket system, which is specially used for installing cable equipment. It has the characteristics of simple structure, flexible configuration and easy installation. This bracket system is mainly composed of columns and bracket arms (cross arms). The connection between the bracket arm and the column is to insert the bracket arm directly into the column and then fix it with a positioning pin. After the cable is placed on the top of the bracket, when the cable is laid, the construction workers may accidentally apply lateral force to the cable during operation, such as pulling and pushing the cable to adjust the position, etc. These forces will be transmitted to the bracket. Secondly, when multiple cables are laid in parallel, the cables may squeeze and rub against each other, causing some of the cables to generate lateral thrust on the bracket. After the bracket is subjected to lateral tension, it will cause the bracket to deform, thereby reducing the service life of the bracket. In addition, when the bracket arm breaks during long-term use and needs to be replaced, the cables are usually densely arranged and intertwined with each other, which makes it difficult to directly contact the bracket arm that needs to be replaced without moving or untying other cables, making it very inconvenient to operate when the bracket arm breaks and needs to be replaced.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example

[0030] Reference Figure 1-Figure 10 , which is the first embodiment of the present invention, provides a combined cable installation bracket, the combined cable installation bracket includes a bracket assembly 100, including a column 101.

[0031] The column 101 is fixed to the wall by bolts and is used to support the bracket arm.

[0032] The rotating assembly 200 is arranged in the column 101, and includes a support plate 201a, a rotating frame 201b, a rotating column 201c, a positioning shaft 201d, a support block 201e and a limiting column 201f. The column 101 is provided with a slot 101-1, the support plate 201a is inserted into the slot 101-1, the rotating frame 201b is located at the top of the support plate 201a, the rotating frame 201b is provided with a through hole 201b-4, the rotating column 201c is arranged in the through hole 201b-4, the positioning shaft 201d is located between the rotating column 201c and the rotating frame 201b, the support block 201e is fixed in the column 101, and the rotating column 201 c is rotatably connected with the support block 201e through a bearing, the limiting column 201f is located in the positioning shaft 201d, a spiral groove 201c-1 is provided on the rotating column 201c, the positioning shaft 201d slides in the spiral groove 201c-1, a guide groove 201b-1 is provided in the rotating frame 201b, the positioning shaft 201d slides in the guide groove 201b-1, a first limiting hole 201b-2 is provided in the rotating frame 201b, one end of the limiting column 201f is inserted into the first limiting hole 201b-2, a second limiting hole 201c-2 is provided on the rotating column 201c, and the second limiting hole 201c-2 cooperates with the limiting column 201f.

[0033] The support plate 201a is U-shaped and is used to support the rotating frame 201b. The rotating frame 201b is used to install and fix the supporting arm 102. The support block 201e is used to support the rotating column 201c.

[0034] When the limiting column 201f is engaged with the first limiting hole 201b-2, the positioning shaft 201d is connected to the rotating frame 201b through the cooperation of the two. When the broken support arm 102 needs to be replaced, the support plate 201a is first pulled outward to release its support for the rotating frame 201b, and then the rotating column 201c is rotated. At this time, the positioning shaft 201d will slide along the inner wall of the spiral groove 201c-1. The cooperation of the two can drive the rotating frame 201b to move downward, so that the rotating frame 201b moves to the bottom of the cable, thereby making enough space to replace the broken support arm 102 without untying the cable. At the same time, during the replacement process, the operation is convenient and will not be hindered by the cable.

[0035] When the limiting column 201f is engaged with the second limiting hole 201c-2 and separated from the first limiting hole 201b-2, the positioning shaft 201d is connected to the rotating column 201c through the cooperation of the two, so that the positioning shaft 201d cannot move. In this state, when the cable moves at the top of the support arm 102 under tension and generates a lateral tension on the support arm 102, the support arm 102 will rotate to offset the generated tension. When the support arm 102 rotates, it will drive the rotating frame 201b to rotate, and the positioning shaft 201d will By sliding in the guide groove 201b-1, the cooperation of the two can drive the rotating frame 201b and the support arm 102 to move upward while rotating. When the tension generated by the cable disappears, the support arm 102 will move downward due to the weight of the cable, and again through the cooperation of the positioning shaft 201d and the guide groove 201b-1, the support arm 102 is rotated to the initial state, and then can continue to provide support for the cable, thereby avoiding the situation where the support arm 102 is subjected to lateral tension, which will cause the overall bracket to deform, thereby reducing its service life. Example

[0036] Reference Figure 1-Figure 10 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0037] Specifically, a movable groove 201b-3 is opened in the rotating frame 201b, and a push block 202a is arranged in the movable groove 201b-3. One side of the push block 202a is inclined and contacts the end of the limiting column 201f. A connecting rod 202b is fixed to the bottom of the push block 202a, and a first spring 202c is fixed to the bottom of the connecting rod 202b. A trigger plate 202d is arranged in the rotating frame 201b.

[0038] The movable groove 201b-3 is connected to the first limiting hole 201b-2. The connecting rod 202b is L-shaped, and one end extends into the rotating frame 201b, which is located below the trigger plate 202d.

[0039] In the initial state, the limit column 201f is engaged with the first limit hole 201b-2. After the support arm 102 is inserted into the rotating frame 201b, its bottom will contact the trigger plate 202d. At this time, the trigger plate 202d will not move downward. When the support arm 102 is placed with a cable, the weight of the cable will drive the support arm 102 to move downward, and press the trigger plate 202d downward through the support arm 102. At this time, the trigger plate 202d will drive the connecting rod 202b to move downward, and drive the push block 202a to move downward through the connecting rod 202b, so that the push block 202a is squeezed on the inclined surface of the limit column 201f, thereby pushing the limit column 201f to move, and then the limit column 201f can be separated from the first limit hole 201b-2, and the other end is engaged with the second limit hole 201c-2.

[0040] Therefore, only when the cable is placed on the top of the support arm 102, the positioning shaft 201d will be connected to the rotating column 201c. At this time, the rotating frame 201b will rotate when subjected to tension. When there is a cable in the top of the support arm 102, the positioning shaft 201d will be connected to the rotating frame 201b. At this time, the rotating frame 201b can be driven to move downward by rotating the rotating column 201c, thereby facilitating the replacement of the broken support arm 102.

[0041] When the connection rod 202b is released from restriction, the first spring 202c applies an upward thrust to the connection rod 202b, so that the connection rod 202b can drive the push block 202a to reset and separate the push block 202a from the limiting column 201f.

[0042] Specifically, a connecting sleeve 203a is fixed at the bottom of the rotating frame 201b, and a fixed sleeve 203b is rotatably connected to the connecting sleeve 203a through a bearing. A clamping block 203c is fixed to one side of the fixed sleeve 203b. A clamping slot 101-2 is provided in the column 101, and the clamping block 203c slides in the clamping slot 101-2. A chamber 203c-1 is provided in the clamping block 203c, and a limiting block 203d is movably connected to the chamber 203c-1. A limiting groove 201c-3 is provided on the rotating column 201c, and the limiting groove 201c-3 cooperates with the limiting block 203d.

[0043] The fixed sleeve 203b is connected to the rotating frame 201b through the connecting sleeve 203a, so that it can move up and down with the rotating frame 201b, and the rotating frame 201b will not interfere with it when it rotates. The clamping block 203c is T-shaped, and there are two of them, which are fixed on both sides of the fixed sleeve 203b respectively. When the limit block 203d is engaged with the limit groove 201c-3, the rotating column 201c can be locked through the cooperation of the two, so that it cannot rotate, thereby avoiding the situation that the rotating column 201c will be driven to rotate when the rotating frame 201b rotates, thereby making the rotating frame 201b unable to reset.

[0044] Specifically, a push rod 204a is inserted into the blocking block 203c, and a force groove 203d-1 corresponding to the push rod 204a is opened on the limiting block 203d, and the inner wall of the force groove 203d-1 is inclined. A second spring 204b is fixed to one side of the limiting block 203d, and one end of the second spring 204b is fixed to the inner wall of the chamber 203c-1. A guide column 204c is fixed to one side of the fixed sleeve 203b, and the guide column 204c is movably connected with the push rod 204a. A fourth spring 204d is fixed to one side of the push rod 204a, and one end of the fourth spring 204d is fixed to the fixed sleeve 203b.

[0045] The push rod 204a is U-shaped. When the push rod 204a moves, it will squeeze the inner wall slope of the force groove 203d-1, thereby pushing the limit block 203d to move, and then the limit block 203d can be engaged with the limit groove 201c-3. At this time, the push rod 204a can still continue to move in the force groove 203d-1 and penetrate to the outside of the block 203c.

[0046] When the push rod 204a is released from restriction, the fourth spring 204d applies a thrust to the push rod 204a, thereby resetting the push rod 204a and releasing the squeezing of the inner wall of the force groove 203d-1. At the same time, the second spring 204b applies a pulling force to the limit block 203d and separates the limit block 203d from the limit groove 201c-3.

[0047] The guide column 204c is used to position the push rod 204a to prevent it from being offset during movement.

[0048] Specifically, an extrusion rod 205a is fixed to the bottom of the trigger plate 202d, one side of the bottom end of the extrusion rod 205a is inclined and contacts the push rod 204a, a mounting block 205b is fixed to one side of the extrusion rod 205a, a third spring 205c is fixed to the top of the mounting block 205b, and the top of the third spring 205c is fixed to the rotating frame 201b.

[0049] When the support arm 102 is inserted into the rotating frame 201b and contacts the top of the trigger plate 202d, the trigger plate 202d is supported by the third spring 205c so that it does not move downward. When a cable is placed on the top of the support arm 102, the weight of the cable can drive the support arm 102 and the trigger plate 202d to move downward, so that the trigger plate 202d drives the squeezing rod 205a to move downward, so that the bottom end of the squeezing rod 205a can squeeze the push rod 204a and push the push rod 204a to move.

[0050] When the rotating frame 201b is rotated by the pulling force, the squeezing rod 205a will be driven to rotate at the same time. At this time, the squeezing rod 205a will continue to push the push rod 204a to move.

[0051] Specifically, a fixing ring 206a is fixed inside the positioning shaft 201d, an annular groove 201f-1 is opened on the outside of the limiting column 201f, the fixing ring 206a is movably connected to the annular groove 201f-1, a fifth spring 206b is fixed on one side of the fixing ring 206a, and one end of the fifth spring 206b is fixed to the inner wall of the annular groove 201f-1.

[0052] When the pushing block 202a is separated from the limiting column 201f, the limiting column 201f can be pushed to return to the initial state by the fifth spring 206b. Example

[0053] Reference Figure 1-Figure 10 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0054] Specifically, a positioning plate 207a is provided in the through hole 201b-4, a support rod 207b is fixed on the top of the positioning plate 207a, both ends of the support rod 207b are fixed to the inner wall of the column 101, a sliding groove 207a-1 is provided on the positioning plate 207a, the positioning shaft 201d is movably connected with the sliding groove 207a-1, a positioning ring 207c is fixed on the outer side of the positioning shaft 201d, a positioning groove 207a-2 is provided on the positioning plate 207a, and the positioning ring 207c slides in the positioning groove 207a-2.

[0055] The positioning shaft 201d is positioned by the slide groove 207a-1 to prevent it from being offset, and the positioning ring 207c cooperates with the positioning groove 207a-2 to prevent the positioning shaft 201d from being displaced to both sides.

[0056] Specifically, a buffer block 208 is fixed inside the column 101 . There are two buffer blocks 208 , which are respectively located on two sides of the rotating frame 201 b . The buffer blocks 208 are in contact with the rotating frame 201 b .

[0057] The buffer block 208 is used to support and position the rotating frame 201b to prevent the rotating frame 201b from rotating randomly. At the same time, when the rotating frame 201b rotates under the lateral pulling force, the buffer block 208 can also buffer the rotating frame 201b to prevent the rotating frame 201b from rotating at too large a speed and amplitude.

[0058] When the rotating frame 201b rotates, the buffer block 208 is squeezed, and the buffer block 208 squeezes the column 101, so that the connection between the column 101 and the wall can be tightened, thereby avoiding the situation where the connection between the column 101 and the wall is subjected to tension when the rotating frame 201b rotates.

[0059] Specifically, there are two guide grooves 201b-1, which are located at two sides of the rotating frame 201b respectively. The guide grooves 201b-1 are inclined downward and overlap with the circular inner wall of the through hole 201b-4. The two guide grooves 201b-1 are symmetrically arranged.

[0060] By providing the two guide grooves 201b-1, the rotating frame 201b can be rotated in two directions.

[0061] Specifically, the bracket assembly 100 also includes a bracket arm 102 and a pin 103. The bracket arm 102 is inserted into the rotating frame 201b. The pin 103 is inserted into the bracket arm 102. The rotating frame 201b is provided with a through slot 201b-5, and the end of the pin 103 is located in the through slot 201b-5.

[0062] The support arm 102 is connected to the rotating frame 201b by the pin 103, and the through slot 201b-5 is provided so that the support arm 102 can have space to move downward inside the rotating frame 201b.

[0063] In summary, the combined cable installation bracket of the present invention has the following advantages: When subjected to lateral tension from the cable, it can adaptably rotate without causing deformation, thereby increasing its service life; When the support arm 102 is broken and needs to be replaced, there is no need to untie the cable, thereby improving the convenience of replacing the support arm 102; When the cable is placed on the top of the bracket arm 102, the bracket arm 102 can also be buffered by the third spring 205c to prevent the weight applied by the cable from instantly impacting the connection between the column 101 and the wall; When the bracket arm 102 is rotated by a lateral pulling force, the buffer block 208 can increase the stability of the connection between the column 101 and the wall, thereby preventing the connection between the column 101 and the wall from loosening due to the pulling force. The rotating assembly 200 can automatically switch between two states, thereby improving the convenience of using the device.

[0064] When in use, first fix the column 101 in the specified position by bolts, and then insert the support arm 102 into the rotating frame 201b. At this time, the cable can be placed on the top of the support arm 102, and the weight of the cable will drive the support arm 102 to move downward, and press the trigger plate 202d downward through the support arm 102. At this time, the trigger plate 202d will drive the connecting rod 202b to move downward, and drive the push block 202a to move downward through the connecting rod 202b, so that the push block 202a is squeezed on the inclined surface of the limit column 201f, thereby pushing the limit column 201f to move, and then the limit column 201f can be separated from the first limit hole 201b-2, and the other end is engaged with the second limit hole 201c-2.

[0065] By cooperating with each other, the positioning shaft 201d is connected to the rotating column 201c, so that the positioning shaft 201d cannot move. In this state, when the cable is subjected to tension and moves at the top of the support arm 102, and a lateral tension is generated on the support arm 102, the support arm 102 will rotate to offset the generated tension. When the support arm 102 rotates, it will drive the rotating frame 201b to rotate. At this time, the positioning shaft 201d will slide in the guide groove 201b-1. By cooperating with the two, the rotating frame 201b and the support arm 102 can be driven to move upward while rotating. When the tension generated by the cable disappears, the support arm 102 will move downward due to the weight of the cable, and again through the cooperation of the positioning shaft 201d and the guide groove 201b-1, the support arm 102 is rotated to the initial state, and then it can continue to provide support for the cable, thereby avoiding the situation where the support arm 102 is subjected to a lateral tension, which will cause the overall bracket to deform, thereby reducing its service life.

[0066] At the same time, the trigger plate 202d will drive the squeezing rod 205a to move downward, so that the inclined surface of the bottom end of the squeezing rod 205a can squeeze the push rod 204a and push the push rod 204a to move. When the push rod 204a moves, it will squeeze the inclined surface of the inner wall of the force groove 203d-1, thereby pushing the limit block 203d to move, and then the limit block 203d can be engaged with the limit groove 201c-3. Through the cooperation of the two, the rotating column 201c can be locked and prevented from rotating, thereby preventing the rotating frame 201b from driving the rotating column 201c to rotate when rotating, thereby preventing the rotating frame 201b from being able to reset.

[0067] When the support arm 102 breaks after long-term use, the broken support arm 102 can no longer support the cable, so the third spring 205c will drive the squeezing rod 205a and the trigger plate 202d to move upward, and separate the squeezing rod 205a from the push rod 204a. At this time, the push rod 204a is reset by the fourth spring 204d. At the same time, the second spring 204b will apply a pulling force to the limit block 203d, and separate the limit block 203d from the limit groove 201c-3, thereby releasing the restriction on the rotating column 201c.

[0068] The first spring 202c applies an upward thrust to the connecting rod 202b, so that the connecting rod 202b drives the push block 202a to reset and separates the push block 202a from the limiting column 201f. The fifth spring 206b pushes the limiting column 201f to reset to the initial state, and the limiting column 201f is engaged with the first limiting hole 201b-2. The two cooperate to connect the positioning shaft 201d to the rotating frame 201b.

[0069] At this time, first pull the support plate 201a outward to release its support for the rotating frame 201b, and then rotate the rotating column 201c. At this time, the positioning shaft 201d will slide along the inner wall of the spiral groove 201c-1. Through the cooperation of the two, the rotating frame 201b can be driven to move downward, so that the rotating frame 201b moves to the bottom of the cable, thereby making enough space to replace the broken support arm 102 without untying the cable. At the same time, during the replacement process, the operation is convenient and will not be hindered by the cable. When the support arm 102 is replaced, the rotating frame 201b can be reset upward.
