Description

Technical Field

[0001] This utility model relates to the field of power fittings technology, and in particular to a high-strength bowl-shaped hanging plate. Background Technology

[0002] In transmission lines, the bowl-shaped hanging plate serves to suspend insulator strings and suspension clamps, and bears a large working stress. Its safety performance is crucial to the transmission line.

[0003] Existing Chinese patent document CN202321943037.9 discloses a bowl-shaped hanging plate. This utility model includes a bowl-shaped hanging plate body and a bolt body. The bowl-shaped hanging plate body includes a bowl-shaped base, and two vertical plates are fixedly connected to the bottom of the bowl-shaped base. The bolt body includes a screw rod, with both ends of the screw rod passing through the two vertical plates and extending to the outside of the vertical plates. A positioning pin is provided on the screw rod. The positioning pin includes a penetrating pin and a pressing pin connected together. By setting a first inclined part and a second inclined part, it is convenient to pass the penetrating pin through the pin hole of the screw rod, and the pressing pin is pressed against the surface of the screw rod, so that the positioning pin composed of the penetrating pin and the pressing pin is not easy to loosen, and the positioning effect of the nut is better. Furthermore, the cavity formed between the penetrating pin and the pressing pin by the first arc-shaped part and the second arc-shaped part makes it easy to operate with fingers through the penetrating pin and the pressing pin, and the removal and removal of the penetrating pin and the pressing pin are simpler.

[0004] However, the above-mentioned patent has certain defects in use. Since the bowl head plate is usually located at a high altitude and serves to suspend the insulator string, when the bowl head plate is subjected to a large wind force at a high altitude, the ball head in the device is only limited by the R-type pin. When the pulling force is large, it may detach, which may cause danger.

[0005] To address these issues, a high-strength bowl-shaped hanging plate is proposed. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a high-strength bowl head hanging plate.

[0007] This utility model is achieved using the following technical solution:

[0008] A high-strength bowl head hanging plate includes a bowl head and a hanging plate. The hanging plate is erected vertically and has two plates, which are symmetrically fixed to the lower surface of the bowl head. The bowl head has a ball socket inside for connecting an external ball head. The front of the bowl head has two fixing seats, which are symmetrically fixed to both sides of the bowl head. The fixing seats are equipped with a blocking bar.

[0009] The barrier bar is C-shaped, and one end of the barrier bar is provided with a pivot. The pivot is fixedly connected to the barrier bar and is installed in the fixed seat on the left side, so that the barrier bar can rotate freely in the fixed seat on the left side.

[0010] The other end of the barrier bar is provided with a fixed post, the outer wall of the fixed post is provided with threads, the fixed post and the barrier bar are rotatably connected, the right side fixed seat is provided with internal threads, and the fixed post is threadedly connected to the right side fixed post.

[0011] The bowl head is provided with a pin hole, which penetrates the bowl head. A flexible pin is provided in the pin hole. The flexible pin is "M" shaped and is placed at the bottom of the ball socket. The end of the flexible pin passes through the pin hole and is engaged in the pin hole.

[0012] The elastic pin has ear plates at both ends, and through holes are provided on the ear plates. The ear plates are in close contact with the back of the bowl head. On the back of the bowl head, there are fixing holes on both sides of the pin hole. The ear plates are fixed to the bowl head by fixing bolts.

[0013] The mounting plate is provided with connecting bolts, and the end of the connecting bolts is provided with nuts to fix the connecting bolts and the mounting plate. The end of the connecting bolts is provided with cotter pins.

[0014] The present invention has the following advantages over the prior art:

[0015] 1. A C-shaped stop bar is installed on the front of the bowl head. One end of the stop bar is connected to the left-side fixed seat via a pivot, allowing it to rotate freely within a certain range. The other end of the stop bar has a fixed post, which is threadedly connected to the right-side fixed seat for locking. When the stop bar rotates to the predetermined position, it can be locked through the threaded connection between the fixed post and the right-side fixed seat, effectively blocking and fixing the ball head. This effectively blocks and fixes the external ball head, preventing it from loosening or falling off, and improving connection stability. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figures 1 to 4 As shown, a high-strength bowl head 1 mounting plate 7 includes a bowl head 1 and a mounting plate 7. The mounting plate 7 is vertically erected and has two parts, which are symmetrically fixed to the lower surface of the bowl head 1. The function of the mounting plate 7 is to connect to the tower or other structural components through connecting bolts 5, so as to ensure that the bowl head 1 mounting plate 7 can be firmly installed in the predetermined position. The bowl head 1 has a ball socket 2 inside for connecting the external ball head. The front of the bowl head 1 has two fixing seats 33, which are symmetrically fixed on both sides of the bowl head 1. The fixing seats 33 are equipped with a blocking bar 3.

[0024] The barrier bar 3 is C-shaped. One end of the barrier bar 3 is provided with a rotating shaft 31. The rotating shaft 31 is fixedly connected to the barrier bar 3. The rotating shaft 31 is installed in the fixed seat 33 on the left side, so that the barrier bar 3 can rotate freely in the fixed seat 33 on the left side.

[0025] The other end of the barrier bar 3 is provided with a fixing post 32. The outer wall of the fixing post 32 is provided with threads. The fixing post 32 and the barrier bar 3 are rotatably connected. The fixing seat 33 on the right side is provided with internal threads. The fixing post 32 is threadedly connected to the fixing post 32 on the right side.

[0026] The bowl head 1 is provided with a pin hole 12, which penetrates the bowl head 1. An elastic pin 4 is provided inside the pin hole 12. The elastic pin 4 is "M" shaped and is placed at the bottom of the ball socket 2. The end of the elastic pin 4 passes through the pin hole 12 and is engaged in the pin hole 12. When the external ball head is inserted into the ball socket 2, it will squeeze the end of the elastic pin 4, causing it to deform and engage in the pin hole 12, thereby further fixing the ball head. The elastic pin 4 has excellent elasticity and locking performance. When the ball head is inserted into the ball socket 2, it will squeeze the end of the elastic pin 4, causing it to deform and engage in the pin hole 12. In this way, the elastic pin 4 can effectively fix the external connector to prevent it from loosening or falling off.

[0027] The elastic pin 4 has ear plates 41 at both ends, and through holes are opened on the ear plates 41. The ear plates 41 are in close contact with the back of the bowl head 1. On the back of the bowl head 1, there are fixing holes 11 on both sides of the pin hole 12. The ear plates 41 are fixed to the bowl head 1 by fixing bolts 13. This not only ensures the stable installation of the elastic pin 4, but also prevents it from falling off during use.

[0028] A connecting bolt 5 is threaded through the hanging plate 7, and a nut is provided at the end of the connecting bolt 5 to fix the connecting bolt 5 and the hanging plate 7. A cotter pin 6 is also threaded through the end of the connecting bolt 5. The connecting bolt 5 passes through the hanging plate 7 to connect with the external structural components, and the connection is ensured by tightening the nut. The cotter pin 6 is placed at the end of the connecting bolt 5 to prevent the nut from loosening during use. In this way, even under the action of external forces (such as vibration, impact, etc.), the connecting bolt 5 and the nut are difficult to loosen or fall off, thereby ensuring that the connection of the entire bowl head 1 hanging plate 7 is stable and reliable.

[0029] The working principle of this utility model is as follows: When in use, the ball head is inserted into the ball socket 2 of the bowl head 1. At this time, the end of the elastic pin 4 will be squeezed and deformed, and it will be inserted into the pin hole 12 to initially fix the external connector.

[0030] Next, rotate the barrier bar 3 from its initial position to a position where it can fit snugly against the surface of the external connector. During rotation, one end of the barrier bar 3 rotates freely within the left fixed seat 33 via the pivot 31, while the other end is adjusted via a threaded connection between the fixed post 32 and the right fixed seat 33.

[0031] Once the barrier bar 3 is adjusted to the appropriate position, tighten the nut on the fixing post 32 to securely lock the barrier bar 3 in the predetermined position, thereby effectively blocking and fixing the ball head. In this way, even under the action of external forces (such as wind, vibration, etc.), the ball head will be difficult to fall off the hanging plate 7 of the bowl head 1.

[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
