[0002] In modern engineering construction, iron accessories are key components that connect and support various types of equipment, and the accuracy and stability of their installation are crucial. However, the iron accessory brackets currently available on the market have many drawbacks. Common bracket adjustment methods are single, making it difficult to cope with complex and changing installation environments. For example, in mountainous power transmission lines, the tower foundation may have a slope. When installing iron accessories such as crossarms and insulator strings on this foundation, the angle and position of the bracket must be adjusted according to the tower inclination and the direction of the conductor. Although some brackets have adjustment functions, the adjustment operation is complicated and tedious, which not only increases the difficulty of construction but also easily leads to adjustment errors, affecting the accuracy of iron accessory installation. Moreover, after adjustment, these brackets often have poor stability problems due to unreasonable structural design. They are prone to loosening during use, seriously threatening the normal operation and safety of the equipment. In addition, some brackets lack versatility and are difficult to adapt to different installation bases and iron accessory types, increasing equipment procurement and installation costs. Therefore, it is necessary to develop a multi-directionally adjustable iron accessory bracket structure to address the above-mentioned shortcomings. Summary of the Invention

[0021] The core of this invention is to provide a multi-directionally adjustable iron accessory bracket structure. Through angle adjustment components and horizontal adjustment components, the iron accessory bracket can be adjusted in multiple directions in both angle and horizontal direction. It is suitable for complex and changing installation environments, is easy to operate, and improves the installation efficiency of iron accessories.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0024] With reference to the accompanying drawings, Figure 1 This is a schematic diagram of the installation structure of the multi-directionally adjustable iron accessory bracket structure of the present invention; Figure 2 Schematic diagram of the installation structure of the worm gear of the present invention; Figure 3 Schematic diagram of the installation structure of the worm of the present invention; Figure 4 This is an exploded schematic diagram of the locking assembly of the present invention.

[0025] In one embodiment, Figures 1 to 4As shown, a multi-directionally adjustable iron accessory bracket structure includes a mounting base 6. The mounting base 6 is provided with two pieces and is vertically symmetrically mounted on the outer circumference of the utility pole. A number of mounting holes are provided on both sides of the mounting base 6. The inner side of the mounting base 6 has a semi-circular arc structure. The two sets of mounting bases 6 are symmetrically mounted on both sides of the utility pole and fastened by bolts. Anti-slip pads are adhered to the back surfaces and semi-circular surfaces of both sides of the mounting base 6. The anti-slip pads are made of silicone rubber. The anti-slip pads increase the friction with the side of the utility pole and improve the overall stability. It also includes a base 1, a rotating base 2, a fixed plate 3, a cross arm 4, an angle adjustment component 5 and a horizontal adjustment component 7. The base 1 is arranged horizontally and fixed to the side of the lower end of the mounting base 6 away from the utility pole. The rotating base 2 is arranged at the upper end of the base 1 and is rotatably connected to the base 1 through the angle adjustment component 5 to achieve angle adjustment of the rotating base 2 relative to the base 1. The angle adjustment range is ±30°, and the adjustment accuracy is up to 0.5°. The upper end of the rotating base 2 is equipped with a fixed plate 3, to which a cross arm 4 is mounted. The cross arm 4 is moved horizontally on the fixed plate 3 via a horizontal adjustment assembly 7. The horizontal adjustment accuracy reaches 0.1mm. In actual installation, this structure uses adjustment assemblies on both sides to adjust the angle and horizontal displacement according to the cable installation direction and location, making it suitable for a variety of installation areas. This is different from existing iron accessory brackets, which can only be fixed to the sides of the utility pole and cannot be adjusted. Angled iron accessory brackets must be purchased separately, which is less versatile.

[0026] In one embodiment, Figures 1 to 4 As shown, the angle adjustment assembly 5 includes a worm wheel 501, a worm 502 and a first knob 503. The front end of the base 1 is semicircular, and a groove 101 is provided in the middle for fixing the worm wheel 501. The worm wheel 501 is semicircular and fixedly installed in the groove 101. Arc slide rails 102 with semicircular structures are provided on both sides of the base 1. A slide groove 201 matching the arc slide rail 102 is provided on the side of the rotating base 2 close to the base 1. The rotating base 2 slides on the arc slide rail 102 through the slide groove 201 to achieve rotation. The rotating base 2 is concentric with the worm wheel 501. The worm 502 is rotatably installed on the side of the rotating base 2 close to the base 1 and meshes with the worm wheel 501. One end of the worm 502 extends out of the rotating base 2 and is fixedly connected to the first knob 503. By rotating the first knob 503, the worm 502 is driven to rotate along the worm wheel 501, thereby driving the rotating base 2 to adjust the angle relative to the base 1. The worm gear 501 has a finer pitch, with each tooth corresponding to a 0.5° rotation angle. The first knob 503 is engraved with an angle scale, allowing for accurate control of the rotation angle. The worm gear 501 and worm 502 have a self-locking mechanism, ensuring stability after adjustment.

[0027] In one embodiment, Figures 1 to 4As shown, the horizontal adjustment assembly 7 includes a screw 701, a second knob 702, and a horizontal guide rail 703. The horizontal guide rail 703 is mounted on the horizontal end surface of the fixed plate 3. The lower end of the crossarm 4 slides within the horizontal guide rail 703 via a slider 704. The screw 701 is disposed within the horizontal guide rail 703, passes through the slider 704, and is threadedly connected to the slider 704. Its ends are rotatably mounted on opposite sides of the horizontal guide rail 703. One end of the screw 701 extends out of the fixed plate 3 and is fixedly connected to the second knob 702. The second knob 702 is located on the side of the fixed plate 3 away from the mounting base 6. Rotating the second knob 702 drives the screw 701, thereby causing the crossarm 4 to move horizontally along the axis of the screw 701. The screw 701 has an M8×1.25 fine thread, and each rotation produces 1.25 mm of horizontal movement.

[0028] In one embodiment, Figures 1 to 4 As shown, the locking assembly 8 is also included, which includes a locking block 801, a pressure plate 802, a positioning bead 803, a top post 804 and a spring 805. The locking block 801 is rotatably mounted on the front end of the fixed plate 3 via a rotating shaft. A first foot is provided at one end of the locking block 801, and the first foot can be clamped into the slot of the second knob 702. The front end of the second knob 702 is provided with a plurality of slots evenly distributed along its circumference. A top post 804 is provided at the lower end of the second foot at the other end of the locking block 801. The top post 804 is slidably mounted in the fixed plate 3, and the top post 804 is a hollow structure. The spring 805 is installed inside the top post 804, and one end of the spring 805 abuts against the inner wall of the top post 804, and the other end abuts against the inside of the fixed plate 3. Here, the spring 805 is made of a corrosion-resistant steel wire spring 805. The setting of the spring 805 can support the tilting of the top column 804 and play a supporting role when the locking block 801 moves. Failure has no effect on this function. The upper end face of the top column 804 abuts the lower end face of the second clamping foot. A guide groove is provided on the fixed plate 3 corresponding to the second knob 702. The pressure plate 802 is slidably installed in the guide groove through the guide groove. Positioning beads 803 are provided on both sides of the pressure plate 802. The positioning beads 803 are fixedly installed on the fixed plate 3, and the front end of the positioning beads 803 abuts the side of the pressure plate 802. The inner bottom surface of the pressure plate 802 abuts the upper end face of the locking block 801. The locking assembly 8 locks the second knob 702 by clamping the first clamping foot of the locking block 801 into the clamping groove of the second knob 702, preventing the cross arm 4 from accidentally moving due to vibration or other factors after horizontal adjustment. The optimized locking assembly 8 is more reliable and effectively avoids the problem of affecting the installation quality of iron accessories due to loose adjustment components.

[0029] In one embodiment, Figures 1 to 4As shown, spherical grooves are evenly arranged on both sides of the pressure plate 802. The spherical grooves abut against the ball head at the front end of the positioning bead 803. The pressure plate 802 presses on the upper end of the first clamping foot, and the ball head of the positioning bead 803 falls into the spherical groove on the side of the pressure plate 802 away from the second knob 702. The locking block 801 locks the second knob 702. The ball head of the positioning bead 803 falls into the spherical groove on the side of the pressure plate 802 close to the second knob 702. The pressure plate 802 presses on the upper end of the second clamping foot, and the locking block 801 unlocks the second knob 702. When locking is required, the first clamping foot of the locking block 801 is clamped into the clamping groove of the second knob 702, thereby locking the second knob 702 and preventing the crossarm 4 from accidentally moving due to vibration or other factors after horizontal adjustment. Slide the pressure plate 802 so that the front ball head of the positioning bead 803 falls into the spherical groove at the rear end of the pressure plate 802, pressing the pressure plate 802 against the upper end of the first foot. The pressure plate 802 and the positioning bead 803 ensure the accurate position of the locking block 801. The spring 805 enables the top column 804 to maintain support on the second foot, thereby ensuring the stability of the locking block 801. When unlocking is required, push the pressure plate 802 backward away from the side of the second knob 702. The pressure plate 802 will press the second foot downward, and the locking block 801 will rotate around the shaft. The first foot will disengage from the slot of the second knob 702, causing the front ball head of the positioning bead 803 to fall into the spherical groove at the front end of the pressure plate 802, thereby unlocking the second knob 702.

[0030] The positioning bead 803 used here is a cylindrical body with external threads on the outside and a hollow interior. A steel ball is installed inside, with one-third of the steel ball extending beyond the front end of the externally threaded cylinder. A spring 805 is installed at the bottom of the steel ball, and the back is welded to the bottom end of the externally threaded cylinder. Under the action of the spring 805, the steel ball is squeezed, compressing the spring 805 and falling into the externally threaded cylinder. When there is no squeezing force, it will pop out of the front end of the externally threaded cylinder. The positioning column is fixed to the front end of the fixed plate 3 via the external threads.

[0031] In one embodiment, Figures 1 to 4 As shown, the cross arm 4 is fixedly mounted on the slider 704. A reinforcing rib is provided at the connection between the lower end of the cross arm 4 and the upper end of the slider 704. The reinforcing rib is located at the end away from the mounting seat 6. The reinforcing rib is a triangular structure to enhance the structural strength of the cross arm 4 and the slider 704, thereby improving the overall load-bearing capacity of the cross arm 4.

[0032] In one embodiment, Figures 1 to 4 As shown, the first knob 503 and the second knob 702 are provided with anti-skid protrusions on their surfaces. The height of the anti-skid protrusions is 1.5 mm, which is convenient for construction workers to grasp and operate while wearing gloves.

[0033] The installation process of the multi-directionally adjustable iron accessory bracket structure of the present invention is as follows: two sets of devices are symmetrically placed on either side of a utility pole. Mounting holes are provided on both sides of the mounting base 6, and the mounting base 6 is secured to the utility pole through the mounting holes. When properly installed, due to varying surrounding environments, such as mountainous areas or the upper end of a building, the crossarm 4 may be in a horizontal position during cable installation, which is not conducive to cable installation. Turning the first knob 503 drives the worm 502 to rotate synchronously, thereby driving the worm gear 501 to rotate. The rotation of the worm 502 drives the rotating base 2 along the guide slot 201 and the curved guide rail 102, allowing the rotating base 2 to be adjusted within a ±30° range relative to the base 1. The fixed plate 3 is fixedly mounted on the rotating base 2 and rotates with the rotating base 2. Adjusting the second knob 702 causes the crossarm 4 to move horizontally on the fixed plate 3, adjusting the distance between the crossarm 4 and the utility pole. Turning the second knob 702 rotates the screw 701. Because the screw rod 701 is threadedly connected to the slider 704 at the lower end of the crossarm 4, the slider 704 slides along the horizontal guide rail 703 of the screw rod 701 to adjust the horizontal position. A locking assembly 8 is provided at each second knob 702. The locking block 801 rotates via the rotating shaft, and the first foot engages the slot of the second knob 702. The top column 804, under the action of the spring 805, supports the second foot of the locking block 801, ensuring the stability of the locking block 801 and preventing the second knob 702 from rotating due to factors such as vibration. This locks the horizontal position of the crossarm 4. A pressure plate 802 is provided at the upper end of the locking block 801. The pressure plate 802 is slid, causing the front end ball of the positioning bead 803 to fall into the spherical groove on the side of the pressure plate 802 away from the second knob 702, and the pressure plate 802 presses on the first foot of the locking block 801. This prevents the spring 805 from failing, causing the locking block 801 to be unable to fall into the slot of the second knob 702, resulting in locking failure. Push the pressure plate 802 to move away from the second knob 702, so that the ball head of the positioning bead 803 falls into the spherical slot on the side of the pressure plate 802 close to the second knob 702. The pressure plate 802 presses the second foot of the locking block 801 downward. The locking block 801 rotates around the rotating shaft, and the first foot disengages from the slot of the second knob 702, releasing the lock on the second knob 702 and allowing the crossarm 4 to be adjusted horizontally. This simple structure facilitates adjustment of the crossarm 4 during high-altitude operations.

[0034] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Reference can be made to the common and similar parts between the various embodiments. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method description.
