Description

Technical Field

[0001] The utility model relates to the field of bridge frames, and more specifically, to an adjustable bridge frame. Background Art

[0002] A bridge is a device used to carry and protect cables, wires and other cables, usually made of metal materials such as galvanized steel plates. It has many types, including trough type, tray type, ladder type, etc. The bridge can be fixed on the wall, ceiling or other supporting structure of the building. Its function is to lay the cables neatly and orderly, prevent the cables from being damaged and disturbed, and facilitate the installation, maintenance and management of the cables. It is widely used in various buildings and industrial sites, plays an important supporting role in the safe and stable operation of the electrical system, can adapt to different environments and usage requirements, and is an indispensable infrastructure in electrical engineering.

[0003] In order to adapt to the actual height differences of building structures or other equipment, and to ensure that the cables are laid more smoothly and reasonably in the bridge, it is often necessary to make small adjustments to the installation height during the installation of the bridge. However, most of the bridges in the prior art do not have the adjustment function and are not very practical. At the same time, the installation components thereon (such as screws, nuts, etc.) are easily loosened due to the influence of vibration for a long time, thereby affecting the stability of the bridge installation.

[0004] Therefore, in order to solve the above technical problems, the present application proposes an adjustable bridge. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide an adjustable bridge.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable bridge frame, comprising a bridge frame main body and a mounting rod fixed to the roof, connecting plates with through holes A provided inside are welded on both sides of the bridge frame main body, the ends of the mounting rods are fixedly connected with screws that can pass through the through holes A, the outer side walls of the screws are located on the upper and lower sides of the bridge frame main body and are threadedly connected with nuts, and elastic components are installed on the upper and lower sides of the connecting plates, and when the two nuts move toward the connecting plates, the elastic components are squeezed, so that the elastic components form a rebound force to tighten the nuts to prevent the nuts from loosening.

[0007] Preferably, the elastic component comprises a circular ring plate sleeved on the outer side wall of the screw rod, and a spring is fixedly connected between the circular ring plate and the connecting plate.

[0008] Preferably, the upper and lower sides of the connecting plate are fixedly connected with sliding rods for the sliding sleeve to slide, and the side ends of the sliding sleeve are fixed to the outer side wall of the circular ring plate. When the circular ring plate moves up and down, the circular ring plate will drive the sliding sleeve to move up and down, and the sliding sleeve moves up and down in a straight line along the sliding rod to maintain the up and down linear movement of the circular ring plate, so as to avoid the circular ring plate being rotated by the nut, thereby pulling the spring and causing damage to the spring.

[0009] Preferably, a blocking plate is fixedly connected to one end of the sliding rod opposite to the connecting plate, and the blocking plate is used to prevent the sliding sleeve from separating from the sliding rod.

[0010] Preferably, a partition plate is provided inside the bridge body, and the lateral position of the partition plate is adjustable, so that the internal space of the bridge body can be adjusted according to the actual number of various cables.

[0011] Preferably, a convex groove seat is embedded and fixed at the bottom of the bridge frame body, and a convex block is slidably connected inside the convex groove seat. The top of the convex block is fixed to the bottom of the partition plate. The convex setting makes the convex block have a small head and a large bottom, and the convex groove seat is designed accordingly, so the convex block can be confined in the convex groove seat and can only move in a straight line along the inside of the convex groove seat.

[0012] Preferably, the surface of the convex groove seat is provided with a plurality of through holes B arranged in a transverse array, and the surface of the convex block is provided with screw holes, and the transverse position of the convex block is fixed by screws, and the transverse position of the partition plate is also fixed at the same time.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. After the mounting rod and the roof are fixed, the connecting plates on both sides of the bridge main body are passed through the screw at the bottom of the mounting rod, and the elastic component is also sleeved on the screw, and then the nut below is installed on the screw. By rotating the two nuts above and below the connecting plate, the two nuts move along the screw, and the connecting plate is clamped and fixed at different heights of the screw to fine-tune the height of the bridge main body. When the nut clamps the connecting plate toward the middle part, it moves toward the middle part against the circular plates on the upper and lower sides of the connecting plate, and at the same time squeezes the spring, so that the spring forms a rebound force to press the nut to prevent the nut from loosening, thereby solving the problem that most of the existing bridges in the background technology do not have an adjustment function, are too poor in practicality, and the installation components thereon are easily loosened due to long-term vibration.

[0015] 2. The utility model provides a partition plate inside the main body of the bridge, which can divide the space inside the bridge so as to better classify and lay different types of cables to avoid mutual interference between cables. It is also beneficial to the management and maintenance of cables, and the lateral position of the partition plate can be adjusted to adjust the internal space of the main body of the bridge according to the actual number of various cables.

[0023] like Figure 1-5 As shown, the utility model provides an adjustable bridge frame, including a bridge frame body 1, and a mounting rod 2 fixed to the roof, connecting plates 3 with through holes A4 provided inside are welded on both sides of the bridge frame body 1, and the ends of the mounting rods 2 are fixedly connected with screws 5 that can pass through the through holes A4, and the outer walls of the screws 5 are located on the upper and lower sides of the bridge frame body 1 and are threadedly connected with nuts 7, and elastic components 6 are installed on the upper and lower sides of the connecting plate 3. When the two nuts 7 move toward the connecting plate 3, the elastic components 6 are squeezed, so that the elastic components 6 form a rebound force to press the nuts 7 to prevent the nuts 7 from loosening, and the elastic components 6 include a circular plate 61 sleeved on the outer wall of the screw 5, and a spring 62 is fixedly connected between the circular plate 61 and the connecting plate 3.

[0024] First, fix the mounting rod 2 to the roof. After fixation, pass the connecting plates 3 on both sides of the bridge body 1 through the screw rod 5 at the bottom of the mounting rod 2 (at this time, a nut 7 has been installed on the outer wall of the screw rod 5), and also put the elastic component 6 (that is, the circular ring plate 61 and the spring 62 are sleeved on the screw rod 5), and then install the nut 7 below on the screw rod 5. By rotating the upper and lower nuts 7 of the connecting plate 3, the two nuts 7 move along the screw rod 5, and clamp and fix the connecting plate 3 at different heights of the screw rod 5 to fine-tune the height of the bridge body 1. When the nut 7 clamps the connecting plate 3 toward the middle part, it will move toward the middle part against the annular plates 61 on the upper and lower sides of the connecting plate 3, and at the same time squeeze the spring 62, so that the spring 62 forms a rebound force to press the nut 7 through the annular plate 61 to prevent the nut 7 from loosening (rotating). At the same time, when the bridge frame body 1 vibrates, the spring 62 provides elastic deformation, absorbs and stores energy, and then slowly releases the energy, thereby reducing vibration transmission and impact force, thereby achieving a shock absorption effect.

[0025] Furthermore, the upper and lower sides of the connecting plate 3 are fixedly connected with sliding rods 63 for sliding sleeves 64, and the side ends of the sliding sleeves 64 are fixed to the outer wall of the circular ring plate 61. The end of the sliding rod 63 opposite to the connecting plate 3 is fixedly connected with a blocking plate 65, that is, when the circular ring plate 61 moves up and down, the circular ring plate 61 will drive the sliding sleeve 64 to move up and down, and the sliding sleeve 64 moves up and down in a straight line along the sliding rod 63 to maintain the up and down linear movement of the circular ring plate 61, so as to avoid the circular ring plate 61 being rotated by the nut 7, thereby pulling the spring 62 and causing damage to the spring 62. The blocking plate 65 is used to prevent the sliding sleeve 64 from detaching from the sliding rod 63.

[0026] A partition plate 8 is provided inside the bridge body 1, which can divide the space inside the bridge so as to better classify and lay different types of cables to avoid mutual interference between cables. It is also beneficial to the management and maintenance of cables. The lateral position of the partition plate 8 is adjustable, so that the internal space of the bridge body 1 can be adjusted according to the actual number of various cables.

[0027] The following is the specific structure of the adjustment: a convex groove seat 9 is embedded and fixed at the bottom of the bridge body 1, and a convex block 10 is slidably connected inside the convex groove seat 9, the top of the convex block 10 is fixed to the bottom of the partition plate 8, and the surface of the convex groove seat 9 is provided with a plurality of through holes B11 arranged in a horizontal array, and the surface of the convex block 10 is provided with a screw hole 12, that is, the partition plate 8 is pushed back and forth, and the partition plate 8 drives the convex block 10 to move back and forth, and the convex block 10 moves along the inside of the convex groove seat 9 (the convex setting makes the convex block 10 have a small head and a large bottom, and the convex groove seat 9 is designed correspondingly to it, so the convex block 10 can be restricted in the convex groove seat 9 and can only move in a straight line along the inside of the convex groove seat 9). When the position adjustment is completed, the position of the partition plate 8 can be fixed by passing the screw through the through hole B11 at the corresponding position, and then rotating it clockwise to install it into the screw hole 12.

[0028] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model.
