Description

Technical Field

[0001] This utility model relates to the field of electrical and metering equipment technology, specifically to a four-way steplessly adjustable chassis mounting bracket for a cabinet. Background Technology

[0002] In industrial control and power systems, control cabinets are critical infrastructure that provides centralized installation, protection, operational support, and human-machine interaction for precision electronic and electrical equipment. Their core value lies in providing a safe, reliable, and orderly operating environment for internal components such as relays, PLCs, circuit breakers, contactors, instruments, power supplies, and monitoring units, ensuring the stable and efficient operation of the entire automation system or power distribution network.

[0003] Due to factors such as space being occupied by other facilities in front of the cabinet or incorrect cabinet foundation positioning, the operating space at the front of the cabinet may be compressed, or too many electronic components may be arranged at the front of the cabinet. In such cases, it is impossible to install the chassis from the front of the cabinet, and the back of the cabinet must be opened to install the chassis at the rear. There are two traditional solutions: one is to measure and drill holes on site, use bolts to fix the support strips, and then connect and fix the chassis to the support strips. This method will generate metal shavings during the drilling process, which will cause a short circuit if they fall into a live circuit; the other solution is to weld angle steel brackets inside the cabinet and then install the chassis onto the angle steel brackets. However, this method requires hot work and poses a safety hazard. In addition, after installing using the existing methods, if it is necessary to replace the chassis with a different size, it is necessary to re-drill or re-weld to make the support structure match the new chassis, resulting in poor compatibility. Utility Model Content

[0004] This utility model proposes a four-way steplessly adjustable chassis mounting bracket for screen cabinets. Its purpose is to avoid drilling and welding operations when installing the chassis and to achieve compatibility with chassis of different sizes.

[0005] The technical solution of this utility model is as follows: A four-way stepless adjustable chassis mounting bracket for a screen cabinet includes a horizontal slide rail assembly running left and right and a vertical slide rail assembly horizontally arranged above the horizontal slide rail assembly and perpendicular to its direction. The transverse slide rail assembly includes two first slide rails arranged parallel to each other front to back and running left to right; the longitudinal slide rail assembly includes two second slide rails arranged parallel to each other left to right and running front to back; both the first and second slide rails are telescopic structures; the front end or rear end of the second slide rail is connected to the corresponding first slide rail through a detachable connection structure with relative position adjustment function. The detachable connection structure includes: a first connection hole on a first slide rail, a second connection hole on a second slide rail, and a fastener passing through the first connection hole and the second connection hole and detachably connecting the two; the first connection hole and / or the second connection hole are guide holes with adjustment allowance in their extension direction; The two ends of the first slide rail are detachably connected to the mounting beam of the cabinet. The second slide rail is used to mount the chassis.

[0006] As a further improvement of this utility model, a horizontal groove serving as a first connecting hole is provided on the first slide rail. The horizontal groove is an elongated through hole that penetrates its top and bottom surfaces, and its length direction is consistent with the length direction of the first slide rail.

[0007] As a further improvement of this utility model, the first slide rail includes an outer rail and an inner rail that is slidably nested inside it; the front and rear sides of the outer rail and the inner rail are tightened by fastening bolts arranged opposite to each other.

[0008] As a further improvement of this utility model, the outer rail is a rounded rectangular sleeve, and the inner rail is an inverted U-shaped rod with an opening at the bottom.

[0009] As a further improvement of this utility model, a second longitudinal groove is provided at one end of the second slide rail as a second connecting hole. The second longitudinal groove is a strip-shaped through hole that penetrates its top and bottom surfaces, and its length direction is consistent with the length direction of the second slide rail. The other end of the second slide rail is engaged with the first slide rail.

[0010] As a further improvement of this utility model, the second slide rail includes an outer rail and an inner rail that is slidably nested inside it; the outer rail is provided with a first longitudinal groove, and the inner rail is provided with a positioning hole; the second slide rail also includes a fastener that passes through the first longitudinal groove and the positioning hole.

[0011] As a further improvement of this utility model, the positioning holes are multiple sets of circular positioning holes arranged along the length direction of the inner rail.

[0012] As a further improvement of this utility model, the outer rail is a rounded rectangular sleeve, and the inner rail is an L-shaped connecting rod.

[0013] As a further improvement of this utility model, the chassis is connected to the vertical connecting part provided on the second slide rail via the ear plate.

[0014] As a further improvement of this utility model, the vertical connecting part is an angle steel.

[0015] Compared with the prior art, the present invention has the following advantages: (1) Adjustable installation of the chassis is achieved through two retractable slide rails arranged vertically. The retractable first and second slide rails can be infinitely adjusted in length. The detachable connection structure with relative position adjustment function can further achieve infinitely adjustable spacing between the two sets of first slide rails and infinitely adjustable spacing between the two sets of second slide rails. This bracket makes full use of the mounting beam structure inside the cabinet and adjusts the length and spacing of the two first slide rails to match the existing mounting holes on the mounting beam. This allows it to adapt to cabinets and mounting beams of different specifications as well as chassis of different sizes, greatly improving the flexibility and compatibility of installation.

[0016] (2) This device achieves the installation connection between components through fasteners. No drilling or hot work is required during installation, which avoids the safety hazards caused by falling metal shavings and electric sparks during operation. Attached Figure Description

[0019] The technical solution and effects of this utility model will be described in detail below with reference to specific embodiments and accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0020] like Figure 1 and Figure 2 As shown, a four-way steplessly adjustable chassis mounting bracket for a screen cabinet includes a horizontal slide rail assembly running left and right and a vertical slide rail assembly horizontally positioned above the horizontal slide rail assembly and perpendicular to its direction. Through the vertical cross-coupling of the two sets of slide rails, stepless adjustment of the installation width and depth is achieved, accommodating different specifications of cabinets 1 and mounting beams 2, as well as the installation requirements of chassis of different sizes.

[0021] The horizontal slide rail assembly includes two first slide rails 3 arranged parallel to each other front to back and running left to right. The vertical slide rail assembly includes two second slide rails 4 arranged parallel to each other left to right and running front to back. Both the first slide rails 3 and the second slide rails 4 are telescopic structures. The two ends of the first slide rails 3 are detachably connected to the mounting beams 2 of the cabinet. Specifically, the first slide rails 3 are detachably mounted on the mounting beams 2 located on the left and right sides of the cabinet 1 and running front to back via buckles 33 at both ends.

[0022] Optionally, the first slide rail 3 can also be detachably connected to the mounting beam 2 via fastening bolts.

[0023] The front end of the second slide rail 4 is connected to the first slide rail 3 on the corresponding side through a detachable connection structure with relative position adjustment function.

[0024] The detachable connection structure includes: a first connection hole on the first slide rail 3, a second connection hole on the second slide rail 4, and a fastener that passes through the first connection hole and the second connection hole and detachably connects the two.

[0025] Specifically, in combination Figure 3 As shown, the first slide rail 3 includes an outer rail and an inner rail that slides and nests inside it. The outer rail is a rounded rectangular sleeve, and the inner rail is an inverted U-shaped rod with an open bottom, which can be stably fastened inside the outer rail and can smoothly extend and retract. The length of the first slide rail 3 is locked on the front and rear sides of the outer rail and the inner rail by fastening bolts arranged opposite each other. A set of strip-shaped positioning holes 32 arranged along the length direction of the first slide rail 3 are opened on the top surface of the inner rail. A transverse groove 31, which serves as a first connecting hole, is opened on the first slide rail 3, and the transverse groove 31 and the strip-shaped positioning holes 32 are used for the fastening bolts to pass through.

[0026] The second slide rail 4 also includes an outer rail and an inner rail that slides nested inside it. The difference is that its inner rail is an L-shaped connecting rod, the horizontal section of which is a U-shaped rod with an open top, which can be stably fastened inside the outer rail and can extend and retract smoothly. Its inner rail also includes an upwardly extending vertical connecting part for connecting with the ear plate 51. Optionally, the vertical connecting part is an angle steel.

[0027] The second slide rail 4 has a second longitudinal groove 42 at its front end, which serves as a second connecting hole. The second longitudinal groove 42 is a strip-shaped through hole that penetrates its top and bottom surfaces, and its length direction is consistent with the length direction of the second slide rail 4. The second slide rail 4 has a locking part at its rear end that engages with the transverse groove 31 on the first slide rail 3.

[0028] Furthermore, the outer rail of the second slide rail 4 is provided with a first longitudinal groove 41, the length direction of which is consistent with the length direction of the second slide rail 4, and the inner rail is provided with positioning holes. In this embodiment, the positioning holes are circular through holes opened on the bottom surface of the U-shaped rod, and the positioning holes are arranged at equal intervals along the length direction of the slide rail. The second slide rail 4 also includes a fastening bolt passing through the first longitudinal groove 41 and the positioning hole. The fastening bolt cooperates with the circular positioning hole to provide a multi-level locking position, realizing the adjustment of the total length of the second slide rail 4.

[0029] The method of using the four-way steplessly adjustable mounting bracket described in this embodiment of the invention is as follows: Based on the actual spacing of the mounting beams 2 on the left and right sides of the cabinet, the lengths of the two first slide rails 3 are adjusted by telescopic adjustment so that the buckles 33 at both ends can be reliably engaged with the mounting beams 2 on both sides of the cabinet, and the length of the first slide rails 3 is locked with fastening bolts.

[0030] Based on the spacing of the first slide rail 3 and the width of the chassis to be installed, the lengths and spacing of the two second slide rails 4 are initially adjusted. Then, at the front end of the second slide rail 4, the fastening bolts are passed through the second longitudinal groove 42 of the second slide rail 4, the transverse groove 31 of the first slide rail 3, and the strip-shaped positioning hole 32, and pre-connected with the nuts. At the same time, the snap-fit ​​part at the bottom rear end of the second slide rail 4 is snapped into the transverse groove 31 of the rear side of the first slide rail 3, thereby fixing the second slide rail 4 onto the first slide rail 3.

[0031] Place the chassis body 5 on the two second slide rails 4, so that the ear plates 51 on both sides of the chassis are in contact with the vertical connecting parts on the second slide rails 4, and fix them with fasteners.

[0032] After adjusting the positions of the chassis body 5 and the two second slide rails 4, tighten the pre-connected fastening bolts and nuts at the front end of the second slide rail 4, and lock the length of the second slide rail 4 with fasteners (or lock the length of the second slide rail 4 in advance before installing the chassis body 5).

[0033] Through the above-mentioned structural design and installation method, this utility model realizes the four-way stepless adjustment of the bracket itself (the length adjustment of the first slide rail 3 and the second slide rail 4, the spacing adjustment of the first slide rail 3, and the spacing adjustment of the second slide rail 4), which has the advantages of large adjustment range, flexible installation, and good stability, and can be flexibly compatible with different specifications of cabinets and chassis.

[0034] It should be noted that, as will be apparent to those skilled in the art, this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. The scope of this utility model is defined by the claims rather than the foregoing description.
