Description

Technical Field

[0001] The utility model belongs to the technical field of building construction equipment, in particular to a lighting device used in a construction site. Background Art

[0002] The structure of the lighting equipment used in construction sites is not substantially different from other common lighting equipment. The specific components still include: a base, a column, a top plate, and a lighting lamp body.

[0003] But on the other hand, there are relatively many pedestrians and vehicles passing by on the construction site. As a lighting equipment dedicated to the construction site, it must at least ensure that the basic lighting function will not be affected by accidental collisions.

[0004] For example, a Chinese utility model patent with patent publication number CN219955232U and publication date 2023.11.03 discloses a lighting device for construction, including: a vertical pole, a control box arranged at the end of the vertical pole, a groove is provided in the control box, a pressing rod is arranged in the groove and a cross bar is vertically arranged at the end of the pressing rod, a fixing pin is provided on the cross bar, the fixing pin is parallel to the pressing rod, and the fixing pin is passed through the vertical pole; a lifting rod is sleeved in the vertical pole, the lifting rod is provided with a plurality of pin holes, and the pin holes match the fixing pins; a support rod is arranged at the end of the lifting rod, and a lighting lamp is clamped at the end of the support rod.

[0005] The lighting device in this utility model patent has the following structural principles and advantages: the height of the lighting lamp can be conveniently adjusted through the control box, and can be adapted to different lighting environments; the lighting lamp can be arbitrarily adjusted in its irradiation angle by fixing the rotating block bolt to the support rod; and the lighting device has a simple structure, is easy to install or disassemble, has a low manufacturing cost, is suitable for long-distance transportation, and occupies little space.

[0006] However, in the actual construction and use process, the lighting device still has at least the following two shortcomings, which are also the technical problems to be solved by the present utility model, namely:

[0007] 1. The lifting rod can only adjust the height on the vertical rod, but cannot be rotated, that is, the direction of the lighting cannot be changed, which is very inefficient;

[0008] 2. Once the push rod structure is accidentally touched, the lifting rod will fall accidentally, which is very dangerous. In construction sites with relatively many pedestrians and vehicles passing by, the above-mentioned accidental touch phenomenon is particularly likely to occur.

[0009] Therefore, in summary, there is an urgent need for a new type of lighting equipment that has both lifting and rotating functions and a lifting structure that is not prone to accidental falling, so as to be used on various construction sites. Utility Model Content

[0010] The utility model provides a lighting device for a construction site, which can be arranged on a bottom plate with a vertical round tube, a top plate, an annular positioning block, a threaded square rod unit, an adjusting nut, and a square hole tube unit, so that:

[0011] 1. The vertical height and circumferential facing position of the threaded square rod unit are adjustable;

[0012] 2. The height adjustment structure and the circumferential adjustment structure mentioned above both have protective functions and are not easily touched by mistake, that is, the threaded square rod unit is not easy to fall or rotate and swing.

[0013] The technical solution adopted by the utility model to solve the above-mentioned problem is: a lighting device for construction sites, the structure includes a base plate, a vertical circular tube, and a top plate, and also includes an annular positioning block arranged on the outer ring surface of the vertical circular tube, a threaded square rod unit inserted and arranged on the vertical circular tube and connected to the top plate, an adjusting nut arranged on the threaded square rod unit and used for supporting the upper end surface of the vertical circular tube, and a square hole tube body unit sleeved on the threaded square rod unit, engaged with the annular positioning block, and used to cover the adjusting nut.

[0014] A further preferred technical solution is that the threaded square rod unit includes a vertical rod which is inserted into the vertical circular tube and has a square cross-sectional shape, and four arc-shaped thread segments which are respectively arranged on the four edges of the vertical rod and are all threadedly connected to the adjusting nut.

[0015] A further preferred technical solution is that the number of the adjusting nuts is 2.

[0016] A further preferred technical solution is that the square hole tube body unit includes a square hole circular plate sleeved on the vertical rod, a circular tube arranged on the square hole circular plate and sleeved with the vertical circular tube and used to cover the adjusting nut, and a vertical groove opened upward from the lower end surface of the circular tube and used to engage the annular positioning block.

[0017] A further preferred technical solution is that the number of the vertical slots is 5-10.

[0018] A further preferred technical solution is that the square hole tube body unit also includes a plate with screw holes arranged on the upper surface of the square hole circular plate, and a standby fixing bolt which is arranged on the plate with screw holes and is used to vertically fix the square hole tube body unit by radially clamping the vertical rod inward when the adjusting nut is rotated for adjustment.

[0019] A further preferred technical solution is that the square hole tube unit also includes a lifting ring arranged on the upper surface of the square hole circular plate.

[0020] A further preferred technical solution is that the threaded square rod unit further includes a central through hole arranged on the vertical rod.

[0021] A further preferred technical solution is that: the bottom plate is further provided with a vertical rod located in the vertical circular tube and plugged into the central through hole.

[0022] A further preferred technical solution is that the number of the annular positioning blocks is 1 or 2. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0035] As attached Figure 1-7As shown, a lighting device for construction sites comprises a bottom plate 11, a vertical circular tube 12, and a top plate 13, and also comprises an annular positioning block 1 arranged on the outer annular surface of the vertical circular tube 12, a threaded square rod unit 2 inserted on the vertical circular tube 12 and connected to the top plate 13, an adjusting nut 3 arranged on the threaded square rod unit 2 and used for supporting the upper end surface of the vertical circular tube 12, and a square hole tube body unit 4 sleeved on the threaded square rod unit 2, engaged with the annular positioning block 1, and used for covering the adjusting nut 3.

[0036] In this embodiment, the structure of the lighting device also includes a lighting lamp arranged on the top plate 13, which can be completely fixed or vertically hinged. The circumferential positioning block 1, the threaded square rod unit 2, the adjusting nut 3, the square hole tube unit 4 and the vertical round tube 12 together provide the above lighting lamp with a comprehensive advantage of: stepless height adjustment, circumferential rotation, and height adjustment structure that is not easily changed by accident.

[0037] The bottom plate 11 is fixedly connected to the vertical circular tube 12, and the threaded square rod unit 2 is fixedly connected to the top plate 13. The annular positioning block 1 is in the shape of a rectangular parallelepiped, with the long side being the vertical side. The square hole tube unit 4 can rely on its own weight to be pressed on the adjusting nut 3 after the adjustment is completed, and cover it for protection. Even if the square hole tube unit 4 is hit, the adjusting nut 3 is unlikely to rotate accidentally, that is, the accidental collision of pedestrians and vehicles passing by on the construction site will not cause the above-mentioned lighting to fall.

[0038] In addition, the threaded square rod unit 2 and the vertical round tube 12 can rotate with each other, but cannot rotate with the square hole tube unit 4. Therefore, by actively holding and rotating the square hole tube unit 4, the threaded square rod unit 2 can be rotated, and finally the square hole tube unit 4 and the circumferential positioning block 1 are engaged, so that the direction of the above-mentioned lighting lamp can be fixed stably as needed, so that the lighting device can provide an effective lighting area in a circumferential circle on the construction site, which is very practical.

[0039] The threaded square rod unit 2 includes a vertical rod 201 which is inserted into the vertical circular tube 12 and has a square cross-section, and four arc-shaped thread segments 202 which are respectively arranged on four edges of the vertical rod 201 and are all threadedly connected to the adjusting nut 3 .

[0040] In this embodiment, the cross sections of the four arcuate thread segments 202 are cocircular, and the adjusting nut 3 is always threadedly connected to the four arcuate thread segments 202 , ultimately ensuring that the adjusting nut 3 can stably support the threaded square rod unit 2 on the vertical circular tube 12 .

[0041] In other words, the structure of the vertical rod 201 plus the four arc-shaped thread segments 202 is a common threaded round rod cut away from four full-length longitudinal strips with inferior arc cross sections.

[0042] The number of the adjusting nuts 3 is two.

[0043] In this embodiment, the two adjusting nuts 3 need to be rotated and adjusted one after another, and after the adjustment is completed, the two adjusting nuts 3 are clamped together to ensure that the entire nut structure can be "self-locking" and it is not easy to move up and down spontaneously. Otherwise, the height of the lighting lamp cannot be maintained for a long time.

[0044] The square hole tube unit 4 includes a square hole circular plate 401 which is sleeved on the vertical rod 201, a circular tube 402 which is arranged on the square hole circular plate 401, sleeved with the vertical circular tube 12 and used to cover the adjusting nut 3, and a vertical groove 403 which is opened upward from the lower end surface of the circular tube 402 and is used to engage the annular positioning block 1.

[0045] In this embodiment, the inner annular surface of the circular tube 402 fits as closely as possible to the outer annular surface of the vertical circular tube 12, so that when the square hole tube unit 4 covers and protects the adjusting nut 3, it is not easy to shake or collide.

[0046] In addition, when the square hole tube unit 4 is sealed to protect the adjusting nut 3, its vertical fixing effect is: the square hole circular plate 401 is pressed on the adjusting nut 3, or the inner top surface of the vertical slot 403 is pressed on the annular positioning block 1, to ensure that the adjusting nut 3 is not exposed.

[0047] Finally, the arc-shaped thread segment 202 will not touch the side of the square hole on the square hole circular plate 401, so the thread will not be worn, which is very practical and necessary.

[0048] The number of the vertical slots 403 is 5-10.

[0049] In this embodiment, the rotational displacement effect of the adjusting nut 3 on the arc-shaped threaded section 202 corresponds to the lifting and lowering adjustment of the vertical rod 201 together with the lighting lamp, and the lifting and lowering operation is stepless adjustment, that is, the adjusting nut 3 can provide a finer adjustment range.

[0050] However, the number of the vertical slots 403 is limited, and one of them needs to be engaged with the annular positioning block 1. Therefore, the annular positioning block 1 and the square hole tube unit 4 together provide the above-mentioned lighting lamp with a stable but graded annular rotation effect, which will not affect the normal use of the lighting device.

[0051] The square hole tube body unit 4 also includes a screw hole plate 404 arranged on the upper surface of the square hole circular plate 401, and a standby fixing bolt 405 arranged on the screw hole plate 404 and used to vertically fix the square hole tube body unit 4 by radially clamping the vertical rod 201 inward when the adjusting nut 3 is rotated for adjustment.

[0052] In this embodiment, the plate with screw holes 404 and the standby fixing bolts 405 are used in combination, and are effective only during the rotation of the adjusting nut 3. At this time, the square hole tube unit 4 has been lifted up to expose the adjusting nut 3.

[0053] The direct function of the plate with screw holes 404 and the fixing bolts 405 for waiting for positioning is to temporarily fix the square hole tube unit 4 that has been lifted on the vertical rod 201 until the adjustment of the adjusting nut 3 is completed.

[0054] The indirect effect of the above two is to "liberate" one hand of the operator, so that the operator does not need to hold the square hole tube unit 4 with his hand all the time.

[0055] The square hole tube unit 4 further includes a lifting ring 406 arranged on the upper surface of the square hole circular plate 401 .

[0056] In this embodiment, the lifting ring 406 makes it easier and more convenient to lift the round tube 402. Otherwise, the round tube 402 is relatively large, that is, thick, and requires the operator to hold it with both hands before lifting it up, which is very inconvenient.

[0057] The square hole circular plate 401 and the circular tube 402 are made of hard plastic to ensure sufficient weather resistance and light weight.

[0058] The threaded square rod unit 2 further includes a central through hole 203 arranged on the vertical rod 201 .

[0059] In this embodiment, the advantage of the central through hole 203 , that is, the first function, is to reduce the weight of the threaded square rod unit 2 and alleviate the weight burden of the adjusting nut 3 .

[0060] The bottom plate 11 is also provided with a vertical rod 5 which is located inside the vertical circular tube 12 and plugged into the central through hole 203 .

[0061] In this embodiment, the second function of the central through hole 203 is to obtain two socket relationships of "one inside and one outside" after combining with the vertical rod 5, so that the threaded square rod unit 2 can only be moved up and down and rotated in the circle, and it is more difficult to swing horizontally.

[0062] The vertical rod 5 is a round rod, and the central through hole 203 is a circular through hole, and the two are mutually sleeved, which will not affect the rotation effect of the threaded square rod unit 2.

[0063] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
