Description

Technical Field

[0001] The invention relates to the technical field of lighting equipment, and in particular to a rotating hook device for a high pole lamp. Background Art

[0002] High pole lamps are used as large-scale centralized lighting fixtures in open places such as city squares, airports, and docks. The lamp panel of the high pole lamp is raised and lowered by pulling a wire rope, and the hanging and detaching actions are achieved by the cooperation between the rotating hook device and the hook sleeve on the top of the lamp pole. When the lamp panel completes the hanging and detaching actions, the rotating rod of the rotating hook device will rotate a certain angle, and in order to enable the ground operators to clearly distinguish the rotation angle, an indicator flag needs to be installed on the outside of the rotating rod.

[0003] However, in actual use, high pole lamps often face the problem of bird nesting, especially when some birds build their nests at the indicator flag position of the high pole lamp, which will hinder the rotation of the rotating rod connected to it, and then cause the detachment action between the rotating hook device and the hook sleeve to fail, and the lamp panel cannot be lowered to the ground for maintenance. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a rotating hook device for a high pole lamp. Even if a bird's nest hinders the rotation of an indicator flag, the rotating hook can still be removed to ensure the smooth implementation of subsequent maintenance work.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A rotating hook device for a high pole lamp comprises a base fixed on a lamp panel, a rotating rod rotatably connected in the base and rotatably matched with a hook sleeve on the top of the lamp pole, and an indicator flag assembly symmetrically arranged on both sides of the rotating rod, wherein a deflection sleeve is sleeved on the outer side of the rotating rod, a connecting sleeve for connecting the indicator flag assembly is fixed through the outer wall of the deflection sleeve, a spring plunger is installed in the connecting sleeve, the ball head of the spring plunger points to the rotating rod and matches with a conical groove provided on the surface of the rotating rod. When the indicator flag assembly works normally, the ball head of the spring plunger matches and abuts in the conical groove, so that the deflection sleeve is locked on the rotating rod, and the indicator flag assembly rotates synchronously with the rotating rod to realize the indicating function; when the indicator flag assembly is obstructed, the ball head of the elastic plunger is compressed into the column of the spring plunger under the push of the conical surface, the deflection sleeve is unlocked, and the rotating rod rotates relative to the indicator flag assembly, thereby completing the disassembly action, and ensuring the smooth implementation of subsequent maintenance work.

[0006] Preferably, the indicator flag assembly comprises a horizontally arranged indicator flag and a connecting piece installed on the indicator flag, and an end of the connecting piece is detachably connected to the connecting sleeve.

[0007] Preferably, the connecting sleeve has an internal threaded portion, and the outer side of the cylinder of the spring plunger has an external threaded portion threadably matched with the internal threaded portion.

[0008] Preferably, an adjustment groove is provided on the end surface of the spring plunger body away from the ball head. The spring plunger is threadedly installed in the connecting sleeve, and a screwdriver or other tool is used to adjust the size of the spring plunger extending into the inner side of the deflection sleeve in conjunction with the adjustment groove, thereby adjusting the locking force of the ball head on the rotating rod to avoid deflection of the indicator flag due to external reasons such as wind force.

[0009] Preferably, the connecting member includes a stud bolt and a bending plate horizontally fixed on the indicator flag, one end of the stud bolt is threadedly connected to the connecting sleeve, and the other end of the stud bolt passes through the vertical section of the bending plate, and both sides of the vertical section of the bending plate are clamped and connected by fixing nuts.

[0010] Preferably, the connecting piece further comprises a locking nut, wherein the locking nut is threadedly mounted on an end of the stud bolt away from the indicator flag and an end face of the locking nut abuts against an end face of the connecting sleeve.

[0011] Preferably, the number of the tapered grooves is four, which are divided into two groups, and the two tapered grooves in each group are symmetrically arranged along the central axis of the rotating rod.

[0012] The present invention has the following beneficial effects: The present invention arranges a deflection sleeve, a connecting sleeve and a spring plunger on the outer side of the rotating rod. When the indicating flag assembly works normally, the ball head of the spring plunger cooperates and abuts in the conical groove, so that the deflection sleeve is locked on the rotating rod, and the indicating flag assembly and the rotating rod rotate synchronously to realize the indicating function; when the indicating flag assembly is obstructed, the ball head of the elastic plunger is compressed into the column body of the spring plunger under the push of the conical surface, the deflection sleeve is unlocked, and the rotating rod rotates relative to the indicating flag assembly, thereby completing the detachment action, ensuring the smooth implementation of subsequent maintenance work.

[0022] like Figure 1 As shown, a rotating hook device for a high pole lamp comprises a base 4 fixed on a lamp panel 1, a rotating rod 3 rotatably connected in the base 4 and rotatably matched with a hook sleeve 2 on the top of the lamp pole, and an indicator flag assembly 5 symmetrically arranged on both sides of the rotating rod 3, a deflection shaft sleeve 6 is sleeved on the outer side of the rotating rod 3, specifically, a gap is provided between the deflection shaft sleeve 6 and the rotating rod 3 so that the deflection shaft sleeve 6 can rotate relative to the rotating rod 3, and a connecting sleeve 7 for connecting the indicator flag assembly 5 is penetrated and fixed on the outer wall of the deflection shaft sleeve 6, as shown in FIG. Figure 2 and Figure 5 As shown, a spring plunger 8 is installed in the connecting sleeve 7. In this embodiment, the spring plunger 8 is a prior art, including a column 802, a spring 803 and a steel ball. The column 802 has a chamber for accommodating the spring 803 and the steel ball. One end of the chamber is opened, and the opening size is smaller than the diameter of the steel ball. The steel ball is pressed against the opening under the elastic support of the spring 803, and the steel ball extending out of the opening forms a ball head 801 of the spring plunger 8; specifically, the ball head 801 of the spring plunger 8 is arranged to point to the rotating rod, and cooperates with the conical groove 301 opened on the surface of the rotating rod 3. When the indicating flag assembly 5 is working normally, the ball head 801 of the spring plunger 8 fits and abuts against the conical groove 301, so that the deflection sleeve 6 is locked on the rotating rod 3, and the indicating flag assembly 5 and the rotating rod 3 rotate synchronously to realize the indicating function; when the indicating flag assembly 5 is obstructed, the ball head 801 of the elastic plunger is compressed into the column 802 of the spring plunger 8 under the push of the conical surface, the deflection sleeve 6 is unlocked, and the rotating rod 3 rotates relative to the indicating flag assembly 5, thereby completing the disassembly action, ensuring the smooth progress of subsequent maintenance work.

[0023] Further preferably, in order to make the indicator flag assembly 5 locked by the spring plunger 8 present different indicating directions relative to the lamp panel 1, it is convenient for the operator to observe from different angles, such as Figure 3As shown, there are four conical grooves 301, which are divided into two groups. The two conical grooves 301 in each group are symmetrically arranged along the central axis of the rotating rod 3. During actual installation, the desired indication direction of the indication flag can be selected according to the position where the rotating hook device is installed on the lamp panel 1, that is, the deflection sleeve 6 is rotated until the ball head 801 of the spring plunger 8 is locked with the two symmetrical conical grooves 301.

[0024] Preferably, the indicator flag assembly 5 comprises an indicator flag 501 arranged horizontally and a connector mounted on the indicator flag 501, the end of the connector being detachably connected to the connecting sleeve 7, specifically, the connector comprises a stud bolt 503 and a bending plate 502 horizontally fixed on the indicator flag 501, the connecting sleeve 7 has an internal threaded portion, one end of the stud bolt 503 is threadedly connected to the connecting sleeve 7, the other end of the stud bolt 503 penetrates the vertical section of the bending plate 502, and the two sides of the vertical section of the bending plate 502 are clamped and connected via fixing nuts 504. The arrangement of the above connector has realized the detachable connection of the indicator flag 501, and is convenient for maintenance and replacement of the indicator flag assembly 5.

[0025] Further preferably, Figure 4 As shown, the outer side of the column 802 of the spring plunger 8 has an external threaded portion 804 that is threadedly matched with the internal threaded portion of the connecting sleeve 7. Furthermore, an adjustment groove 805 is provided on the end surface of the column 802 of the spring plunger 8 away from the ball head 801. Specifically, the adjustment groove 805 can be set to a straight slot, a cross slot or a hexagonal slot. A tool such as a screwdriver or a hexagonal wrench is used in conjunction with the adjustment groove 805 to adjust the size of the spring plunger 8 extending into the inner side of the deflection sleeve 6, thereby adjusting the locking force of the ball head 801 on the rotating rod 3 to avoid deflection of the indicator flag 501 due to external reasons such as wind.

[0026] In order to stably connect the indicator flag assembly 5 to the connecting sleeve 7, the connecting piece also includes a locking nut 9, which is threadedly installed on the end of the stud bolt 503 away from the indicator flag 501 and the end face of the locking nut 9 is against the end face of the connecting sleeve 7.

[0027] When the lamp panel 1 is pulled up to the specified height by the wire rope, the rotating hook device approaches and is connected to the hook sleeve 2. The hook sleeve 2 has a guiding inclined surface to rotate the rotating rod 3, thereby driving the deflection shaft sleeve 6 and the indicator flag 501 to rotate together. When birds build nests on the inner circle of the lamp panel 1, the indicator flag 501 and its connecting parts are covered by the bird's nest and connected to the inner circle of the lamp panel 1 by the bird's nest, so that they cannot rotate. At this time, if the lamp panel 1 needs to be repaired, the operation is performed to disengage the hook sleeve 2 from the rotating rod 3. The rotating rod 3 is subjected to a force to generate a large rotational force, while the indicator flag 501 and the connecting parts are affected by the bird's nest and cannot rotate with it. At this time, the steel ball in the spring plunger 8 and the conical groove 301 on the rotating rod 3 move relative to each other under the action of the rotational force. The steel ball overcomes the elastic force of the spring in the spring plunger 8 and moves axially under the action of the inclined surface of the conical groove 301 until the steel ball is separated from the conical groove 301. At this time, the deflection shaft sleeve 6 and the rotating rod 3 can rotate relative to each other, thereby successfully completing the disassembly action.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
