Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] like Figure 1-Figure 5 As shown, the self-locking power distribution equipment provided in the embodiment of the present application includes a distribution box 100, a knob gear 400, a driven gear 500, a first ratchet member 600, a second ratchet member 700, a control knob 800 and a slot frame 900, wherein the distribution box 100 is connected to the bus duct to form the power distribution equipment of this embodiment. The slot frame 900 is a device for fixing the bus duct. In actual use, the bus duct is first fixed on the slot frame 900, and then the bus duct is plugged into the distribution box 100, and then the slot frame 900 is fixed to the distribution box 100 using a locking structure.

[0040] The distribution box 100 includes a top plate 200 and a side plate 300, wherein the side plate 300 is disposed below the top plate 200 and is perpendicular to the top plate 200. Two strip holes 210 are disposed on the upper surface of the top plate 200, and specifically, the two strip holes 210 are disposed at positions of the top plate 200 close to the side plate 300. Furthermore, the two strip holes 210 are symmetrically distributed on the upper surface of the top plate 200 along the center line of the width direction of the top plate 200 as the symmetry axis.

[0041] A collar 410 is provided on the inner surface of the side plate 300, that is, the surface facing the inside of the distribution box. The collar 410 may be a circular ring structure, and a plurality of grooves 411 are provided on the inner ring of the collar 410. The plurality of grooves 411 are equidistantly distributed on the inner ring surface of the collar along the circumferential direction.

[0042] The knob gear 400 is rotatably arranged on the side plate 300. The knob gear 400 is a wheel body with a circle of arranged teeth on the outside. The knob gear 400 is located in the distribution box 100. A wheel shaft 430 is fixedly arranged on the outer surface of the knob gear 400 facing the side plate, and a spring 420 is provided on the outer sleeve of the wheel shaft 430.

[0043] In addition, a circular inner core 820 is sleeved outside the wheel shaft 430, and the outer diameter and shape of the circular inner core 820 are adapted to the inner diameter and shape of the inner ring of the collar 410. In contrast, the outer wall of the circular inner core 820 is provided with a plurality of protrusions 821, and the plurality of protrusions 821 are evenly distributed on the outer wall of the circular inner core 820 along the circumferential direction. The circular inner core 820 is also fixedly connected to one end of the spring 820, and the circular inner core 820 and the wheel shaft 430 are key-connected structures, that is, the circular inner core 820 can slide relative to the wheel shaft 430 in the axial direction, and at the same time, the circular inner core 820 can also control the rotation of the wheel shaft 430 and the knob gear 400.

[0044] Similarly, the driven gear 500 is rotatably arranged on the side plate 300, and the driven gear 500 also has a wheel body with a circle of arranged teeth on the outside. The driven gear 500 is located in the distribution box and is located next to the knob gear 400. The driven gear 500 is meshed and connected with the knob gear 400. In other words, when the knob gear 400 rotates under the action of external force, it can drive the driven gear 500 to rotate at the same time.

[0045] In this embodiment, the first pawl member 600 and the second pawl member 700 both include a ratchet portion 710 and a pawl portion 720, and the ratchet portion 710 and the pawl portion 720 can be integrally formed. The ratchet portion 710 of the first pawl member 600 and the second pawl member 700 is rotatably disposed on the side plate 300, and is respectively meshed and connected with the knob gear 400 and the driven gear 500. The pawl members of the first pawl portion 720 and the second pawl portion 720 are located near the bar hole 210, and the pawl member can rotate with the ratchet portion 710, and pass through the bar hole 210 to extend out of the distribution box 100.

[0046] The control knob 800 passes through the side plate 300 and is fixedly connected to the knob gear 400 . The control knob 800 is fixedly connected to the circular inner core 820 . The control knob 800 can drive the knob gear 400 to rotate.

[0047] In actual use, the bottom surface of the slot frame 900 is in contact with the upper surface of the top plate 200 of the distribution box 100, and a locking groove 910 is provided on the bottom surface of the slot frame 900. When in the installed state, the pawl portion 720 of the first pawl member 600 and the second pawl member 700 will follow the ratchet portion 710 to pass through the strip hole 210 and extend out of the distribution box 100, so that the pawl portion 720 will be clamped in the locking groove 910, thereby fixing the slot frame 900 on the distribution box 100.

[0048] In the self-locking power distribution device provided in the embodiment of the present application, the bottom surface of the slot frame 900 is placed on the top surface of the plug-in box, and the locking groove 910 on the bottom surface of the slot frame 900 is located beside the strip hole 210 opened on the top plate 200. When the slot frame 900 needs to be fixed to the plug-in box, such as Figure 3-Figure 5 As shown, first pull the control knob 800 outward, and drive the circular inner core 820 through the control knob 800 to stretch the spring 420, and at the same time, the circular inner core 820 will be out of the range of the collar. In this way, the control knob 800 can be rotated so that the knob gear 400 drives the driven gear 500 to rotate, and the first pawl member 600 and the second pawl member 700 rotate at the same time. At this time, the pawl parts 720 of the first pawl member 600 and the second pawl member 700 will rotate to the outside of the distribution box through the bar hole 210 until they enter the locking groove 910 and are fixedly connected to the locking groove 910. Finally, the control knob 800 is loosened and the spring 420 is contracted so that the circular inner core 820 is fixed in the inner ring of the collar 410, thereby realizing the function of locking the control knob 800 and the knob gear 400. With the above structural design, the installation process can be realized directly by rotating the pawl member, thereby simplifying the process of the installation process.

[0049] In some embodiments, a partition 110 is also included, such as Figure 3As shown, the partition 110 is arranged inside the distribution box 100 and beside the side plate 300, and the knob gear 400, the driven gear 500, and the first pawl member 600 and the second pawl member 700 are all rotatably arranged between the partition 110 and the side plate 300. Specifically, the cross-sectional shape of the partition 110 can be a trapezoid, and the upper diameter of the partition 110 is smaller than the lower diameter thereof, so that the partition 110 can be adapted to the internal structure of the distribution box 100, thereby improving the adaptability of the partition 110 as an accessory to the distribution box 100.

[0050] In some embodiments, the first pawl member 600 is located obliquely above the knob gear 400, and a first angle is formed between the center of the first pawl member 600 and a line connecting the center of the knob gear 400 and a horizontal line. In contrast, the second pawl member 700 is located obliquely above the driven gear 500, and a second angle is formed between the center of the second pawl member 700 and a line connecting the center of the driven gear 500 and a horizontal line, and the second angle is equal to the first angle.

[0051] In some embodiments, an indicator 810 is further provided on the control knob 800, and a lock position mark and an unlock position mark are provided on the side circumference of the control knob 800; when the indicator 810 of the control knob 800 faces the lock position mark, the first pawl member 600 and the pawl portion 720 of the second pawl member 700 are both located in the lock groove 910 of the slot frame 900. When the indicator 810 of the control knob 800 faces the unlock position mark, the pawl portion 720 of the first pawl member 600 and the second pawl member 700 are both located outside the lock groove 910 of the slot frame 900. In this way, in actual use, an indicator mark that clearly indicates that the device is installed in place can be seen to avoid installation errors, thereby improving the safety level.
