Description

Technical Field

[0001] The utility model relates to the field of cold storage loading and unloading platforms, in particular to a universal folding arm lamp. Background Art

[0002] Cold storage doors are doors installed in cold storage equipment, freezer rooms, and other refrigerated environments to insulate and seal. With advances in refrigeration and freezing technology, cold storage projects are now reaching a wider range of sectors. This increasing penetration of refrigeration and freezing technology has, to a certain extent, increased the demand for cold storage. This increase in the number of cold storage facilities has also led to a growing demand for cold storage panels. It is understood that demand for refrigeration and freezing in my country is increasing at an annual rate of 30%. Summary of the Invention

[0003] The technical problems to be solved by the present invention are as follows: currently, most of the folding arm lights on the loading and unloading platforms of cold storages in China are made of painted carbon steel, which is prone to rust in the low temperature and high humidity platform area, affecting the appearance of the product; most of the folding arm lights in China can only achieve angle adjustment in the horizontal direction, and cannot achieve adjustment to any position and illumination angle according to the height of the refrigerated compartment; the power cords of most of the folding arm lights in China are exposed, which has certain safety hazards and affects the appearance of the product. The present invention provides a universal folding arm light, the main body of which is made of engineering plastic material, which will not rust, thereby improving its own structural strength and reducing the overall weight of the product; the folding arm light can achieve adjustment of the tail downlight to any position and angle through the combination of three horizontal joints and seven turning joints, and can adjust the position and illumination angle to any extent according to the height of the refrigerated compartment; the power cord of the folding arm light is inserted into the cavity of the horizontal joint and the turning joint, and the power cord inside the joint will not leak out at any angle, thereby improving the safety and appearance of the product.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A new universal folding arm lamp, the mounting base of the folding arm lamp is fixed to the wall with drill screws or expansion bolts, and three horizontal joints are fixed together with the mounting base. The three horizontal joints can realize angle adjustment in the horizontal plane, and the horizontal joints mainly play the role of tail support.

[0006] Specifically, one end of the seven directional joints of the folding arm lamp is fixed to the adapter, and the other end is fixed to the three horizontal joints. The tail downlight is fixed to the adapter. The power cord of the downlight is inserted in the cavity of the joint, and the power cord inside will not leak out when the joint is rotated at any angle.

[0007] Specifically, the joints of the folding arm lamp are connected and fixed with bolts and nuts. The bolts and nuts do not protrude from the joint surface. The nuts are clamped by the hexagonal grooves on the joints. When the bolts are tightened, the nuts do not rotate with the bolts. There is a cylindrical support structure in the joint cavity to resist the tightening force of the bolts, prevent joint deformation, and improve the joint connection strength.

[0008] The beneficial effects of the present invention are as follows: the present invention provides a universal folding arm lamp, which is tailor-made for the cold storage loading and unloading platform, is suitable for low temperature and high humidity environments, and can arbitrarily adjust the position and illumination angle according to the height of the refrigerated truck. The folding arm lamp has a smooth surface and no exposed power cord, which solves the shortcomings of traditional folding arm lamps with exposed power cords and limited illumination angles and positions.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0019] like Figure 1 As shown, the mounting base 4 is fixed to the wall with self-tapping screws 8, and the power cord 9 is inserted into the center hole of the mounting base 4, passes through three horizontal joints 1 and seven direction-changing joints 2 and the adapter 3 in sequence, and finally connected to the downlight 7. The power cord 9 is not exposed.

[0020] like Figure 2 As shown, the horizontal joint 1 and the mounting base 4 are fixed by connecting bolts 5 and connecting nuts 6. The front and rear rotation axes of the horizontal joint 1 are parallel, and can achieve horizontal rotation of plus or minus 45 degrees. The function of the horizontal joint 1 is tail support.

[0021] like Figure 3 As shown, the horizontal joint 1 and the direction-changing joint 2 are fixed by connecting bolts 5 and connecting nuts 6. The front and rear rotation axes of the direction-changing joint 2 are vertical, and can rotate plus or minus 45 degrees in the vertical direction. The function of the direction-changing joint 2 is to change the rotation plane. Neither the connecting bolts 5 nor the connecting nuts 6 will protrude from the joint surface. The connecting nut 6 will be stuck in the hexagonal groove of the joint. When the connecting bolt 5 is tightened, the connecting nut 6 will not rotate with the connecting bolt 5.

[0022] like Figure 4 As shown, the direction-changing joint 2 and the adapter 3 are fixed by connecting bolts 5 and connecting nuts 6, and the downlight 7 is fixed to the adapter 3 by its own bolts.

[0023] like Figure 5 As shown, the downlight 7 has achieved a working state of rotating 180 degrees, and the height of the downlight 7 can be adjusted through the joint.

[0024] The folding arm lamp can adjust the tail downlight 7 to any position and angle through the combination of three horizontal joints 1 and seven changing joints 2, making it convenient to illuminate the refrigerated compartment of the cold storage loading and unloading platform, and the position and illumination angle can be adjusted arbitrarily according to the height of the refrigerated compartment.

[0025] The power cord 9 of the folding arm lamp is inserted into the cavity of the horizontal joint 1 and the direction-changing joint 2. The power cord 9 inside the joint will not leak out at any angle, thereby improving the safety and aesthetics of the product.

[0026] When the joints of the folding arm lamp are connected and fixed with bolts, a cylindrical support structure is provided in the joint cavity to resist the tightening force of the bolts, thereby preventing the joint from deforming and improving the joint connection strength.

[0027] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
