[0002] DIN rails are a standard type of metal guide rail widely used to mount circuit breakers and industrial control devices within equipment racks. They are a universally interchangeable rack-mounting system used across many industries; their most significant advantage is that they save time and effort, allowing components to be simply snapped or slid onto the rails, eliminating the need for users to individually mount each component on the panel.
[0003] Usually, external card-type external fixing parts are placed on the guide rails. Their function is to facilitate the connection of various types of devices in addition to standard devices. However, the external fixing parts at the current stage are composed of two parts, one is a base that is slidably connected to the rail, and the other is a load-bearing plate connected to the base with bolts. Both of them take a certain amount of time to disassemble and assemble, which makes it inconvenient to manually disassemble and assemble the external fixing parts and the rail. For this reason, an external card-type guide rail external fixing part is proposed. Utility Model Content

[0020] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0021] The following describes an embodiment of the present invention based on its overall structure.
[0022] An external card type guide rail external fixing part, such as Figures 1 to 4 As shown, it includes a frame seat 100, a force-bearing plate 120 is movably assembled on the front surface of the frame seat 100, and two groups of L-bars 110 are fixed on the rear surface of the frame seat 100;
[0023] The load-bearing plate 120 has a Z-shaped structure. Two sets of reinforcing arms 130 are fixed to the front surface of the frame base 100. A movable arm 132 is movably provided on the outer side of each set of reinforcing arms 130. A pair of springs 131 are fixed between the movable arm 132 and the reinforcing arm 130. Two sets of blind holes 133 are opened at the top of each set of reinforcing arms 130. A positioning rod 124 is fixed to the bottom end of the load-bearing plate 120 and extends into the blind hole 133.
[0024] The bearing plate 120 is in contact with the frame seat 100 and has a notch in the center. The inner wall of the notch is provided with two groups of positioning grooves 121 . A positioning block 134 fixed to the outer wall of the movable arm 132 is slidably provided in each group of positioning grooves 121 .
[0025] The two sets of reinforcing arms 130 fixed to the frame 100 provide better support for the load-bearing plate 120, preventing the load-bearing plate 120 from bending downward due to the heavy weight of the placed standard components, thereby cooperating with the track to achieve the desired effect.
[0026] During installation, the frame 100 is first docked with the track. At this time, external force needs to be applied to the two sets of movable arms 132 to make the movable arms 132 approach the reinforcing arms 130 and compress the springs, and the force-bearing plate 120 is lowered from top to bottom until the positioning rods 124 are inserted into the blind holes 133 and the bottom end of the force-bearing plate 120 is in contact with the reinforcing arms 130. At this point, the external force applied to the movable arms 132 can be removed, the springs 131 release the pressure to restore the movable arms 132, and the positioning blocks 134 enter the positioning grooves 121. In this way, the docking steps of the force-bearing plate 120 and the frame 100 are completed, achieving simplicity and efficiency while improving the strength they can withstand.
[0027] When the external standard is installed on the top of the load-bearing plate 120 , the interval between the two sets of locking blocks 140 can be adjusted according to the threaded holes reserved on the standard, ensuring that various types of standards can be installed on the load-bearing plate 120 .
[0028] Please refer to Figure 3 and Figure 4 A dovetail bar 101 is fixed to the front surface of the frame seat 100 near the two side edges, and a dovetail groove 122 is opened at the contact position between the end surface of the force-bearing plate 120 and the dovetail bar 101.
[0029] By utilizing the cooperation between the dovetail bar 101 and the dovetail groove 122 , the load-bearing plate 120 can be docked with the frame seat 100 according to a preset effect, while increasing the gripping force between the two to ensure that the load-bearing plate 120 will not tilt.
[0030] Please refer to the figure in particular. The end surface of the load-bearing plate 120 away from the frame 100 is provided with two sets of straight grooves 123. A locking block 140 is movably provided in each set of straight grooves 123.
[0031] A threaded hole is formed in the locking block 140 . Constraint blocks extending into the straight groove 123 are formed on the upper and lower surfaces of the locking block 140 . A travel groove is formed at the contact position between the upper inner wall of the straight groove 123 and the constraint block.
[0032] The cooperation between the restraining block and the travel groove can push the locking block 140 to move left and right in the straight groove 123 until it is suitable for the standard to be installed, so that a wide variety of standard models can be installed.
[0033] When in use, the two sets of reinforcing arms 130 fixed to the frame 100 provide better support for the load-bearing plate 120, preventing the load-bearing plate 120 from bending downward due to the heavy weight of the placed standard components, thereby cooperating with the track to achieve the desired effect.
[0034] During installation, the frame 100 is first docked with the track. At this time, external force needs to be applied to the two sets of movable arms 132 to make the movable arms 132 approach the reinforcing arms 130 and compress the springs, and the force-bearing plate 120 is lowered from top to bottom until the positioning rods 124 are inserted into the blind holes 133 and the bottom end of the force-bearing plate 120 is in contact with the reinforcing arms 130. At this point, the external force applied to the movable arms 132 can be removed, the springs 131 release the pressure to restore the movable arms 132, and the positioning blocks 134 enter the positioning grooves 121. In this way, the docking steps of the force-bearing plate 120 and the frame 100 are completed, achieving simplicity and efficiency while improving the strength they can withstand.
[0035] When the external standard is installed on the top of the load-bearing plate 120 , the interval between the two sets of locking blocks 140 can be adjusted according to the threaded holes reserved on the standard, ensuring that various types of standards can be installed on the load-bearing plate 120 .
