Description

Technical Field

[0001] The utility model relates to the technical field of bowl head hanging plates, in particular to an anti-loosening bowl head hanging plate. Background Art

[0002] The bowl head hanging plate is a commonly used hardware equipment on power lines. One end of the bowl head hanging plate is a hat socket, and the other end is a plate shape. It is also called a bowl head hanging ring, a bowl-shaped hanging plate, etc. This structure enables it to play an important role in the power system. The bowl head hanging plate is usually used to support and fix insulator strings. These insulator strings are key devices connecting wires and brackets. Through the firm fixation of the bowl head hanging plate, a safe distance between the wire and the bracket can be maintained to prevent direct contact between the wire and the bracket, thereby ensuring the insulation performance of the line.

[0003] However, because long-distance transmission towers are usually erected relatively high, the wires are suspended in the air and are subject to strong lateral winds, especially in windy weather such as hurricanes, which causes the wires to sway sideways to a large extent, causing the bolts and the bowl head pressing part to shake easily, seriously affecting the stability of the bowl head hanging plate, and even causing it to fall off, thereby causing major accidents. Therefore, those skilled in the art provide an anti-loosening bowl head hanging plate to solve the problems raised in the above background technology. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an anti-loosening bowl head hanging plate to solve the problem that when encountering strong winds such as hurricanes, the wire will produce a large degree of lateral shaking, which will cause the bolt fixing and the bowl head pressing part to shake and fall off easily, thereby causing major accidents.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-loosening bowl head hanging plate, comprising a bowl head seat, fixing plates are installed on both sides of the bottom of the bowl head seat, a T-shaped pull rod is arranged in the bowl head seat, an elastic pressure portion is installed at one end of the T-shaped pull rod, a limiting shaft is installed at the middle part of the bottom of the bowl head seat, a fixing plate is installed at the bottom of the limiting shaft, a pressure spring is arranged on the fixing plate, limiting rods are arranged on both sides of the limiting shaft, a clamping portion is installed at the upper end of the limiting rod, a hook-shaped portion is installed at the lower end of the limiting rod, a limiting plate is installed on the limiting rod, a bolt is connected to the fixing plate, an annular groove is opened on the bolt, a nut is threadedly connected to the other end of the bolt, and a positioning pin is inserted on the bolt.

[0006] Preferably, the limit plate is slidably sleeved with the limit shaft, the upper end of the pressure spring is in pressure contact with the limit plate, and the pressure spring is sleeved on the circumference of the lower limit shaft.

[0007] Preferably, the T-shaped pull rod is slidably plugged into the bowl head seat, and the elastic pressing portion is in pressing contact with the outer wall of the bowl head seat.

[0008] Preferably, the clamping portion passes through the bowl head seat, and the T-shaped pull rod is clamped with the clamping portion, and the T-shaped pull rod is pushed inward so that the T-shaped pull rod is in front of the clamping portion. When the clamping portion protrudes, the T-shaped pull rod retracts backward under the pressure of the elastic pressing portion, so that the T-shaped pull rod is clamped with the clamping portion. At this time, the connecting piece is blocked by the T-shaped clamping rod and will not become detached or loose.

[0009] Preferably, the hook-shaped portion is engaged with the bolt via an annular groove, and under the action of the pressure spring, the hook-shaped portion at the bottom of the limiting rod is engaged with the annular groove, thereby limiting the bolt and preventing the bolt from loosening.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The bowl head hanging plate can fix the bolt and the accessories in the bowl head under the limit of the two ends of the limit rod, thereby avoiding the loosening problem caused by shaking and preventing major accidents. BRIEF DESCRIPTION OF THE DRAWINGS

A limit plate 8 is installed on the limit rod 7. A bolt 9 is connected to the fixing plate 2. An annular clamping groove 10 is opened on the bolt 9. A nut 11 is threadedly connected to the other end of the bolt 9. A positioning pin 12 is inserted on the bolt 9. The limit plate 8 is slidably sleeved with the limit shaft 4. The upper end of the pressure spring 6 is in pressure contact with the limit plate 8. The pressure spring 6 is sleeved on the side of the lower limit shaft 4. The T-shaped pull rod 3 is slidably inserted with the bowl head seat 1, and the elastic pressure portion 301 is in pressure contact with the outer wall of the bowl head seat 1.

[0018] See also Figure 2 , Figure 3The clamping portion 702 passes through the bowl head seat 1, and the T-shaped pull rod 3 is clamped with the clamping portion 702. The T-shaped pull rod 3 is pushed inward so that the T-shaped pull rod 3 is in front of the clamping portion 702. When the clamping portion 702 protrudes, the T-shaped pull rod 3 retracts backward under the pressure of the elastic pressing portion 301, so that the T-shaped pull rod 3 is clamped with the clamping portion 702. At this time, the connecting piece is blocked by the T-shaped clamping rod and will not be disengaged or loosened. The hook-shaped portion 701 is clamped with the bolt 9 through the annular groove 10. Under the action of the pressing spring 6, the hook-shaped portion 701 at the bottom of the limiting rod 7 is clamped with the annular groove 10, thereby limiting the bolt 9 and preventing the bolt 9 from loosening.

[0019] The bowl head hanging plate in the utility model is composed of a bowl head seat 1 and a fixing plate 2, the fixing plate 2 is installed on the lower side of the bowl head seat 1, a T-shaped pull rod 3 is arranged in the bowl head seat 1, the T-shaped clamping rod passes through the bowl head seat 1 and is slidably plugged therewith, a limit rod 7 is arranged between the two fixing plates 2, a hook-shaped portion 701 is installed at the bottom end of the limit rod 7, a clamping portion 702 is installed at the top end of the limit rod 7, and the upper end of the limit rod 7 passes through the bottom side of the bowl head seat 1 and is slidably plugged therewith, and a limit rod 7 is installed in the middle of the bottom side of the bowl head seat 1. A limit shaft 4, a fixed plate 5 is installed at the bottom end of the limit shaft 4, and a pressure spring 6 is installed on the fixed plate 5, a limit plate 8 is installed in the middle of the limit rod 7, the limit plate 8 is slidably sleeved with the limit shaft 4, and the upper end of the pressure spring 6 is in pressure contact with the limit plate 8, a bolt 9 is inserted at the bottom end of the fixed plate 2, the other end of the bolt 9 is fixed by a nut 11, and a positioning pin 12 is inserted at the tail end of the bolt 9 to limit the nut 11, and an annular groove 10 is opened on the bolt 9;

[0020] When the bolt 9 is inserted into the fixing plate 2, the limiting rod 7 is pressed down through the limiting plate 8. When the bolt 9 is inserted into the fixing plate 2, the limiting plate 8 is loosened. Under the action of the pressure spring 6, the hook-shaped portion 701 at the bottom of the limiting rod 7 is clamped with the annular clamping groove 10, thereby limiting the bolt 9 and preventing the bolt 9 from loosening. When the hook-shaped portion 701 at the bottom of the limiting rod 7 is clamped with the annular clamping groove 10, the clamping portion 702 at the top of the limiting rod 7 protrudes from the inside of the bowl head seat 1.
