Description

Technical Field

[0001] The utility model relates to the technical field of elevator installation, in particular to an elevator installation lighting device which is convenient for rapid dust cleaning. Background Art

[0002] An elevator is a vertical lift powered by an electric motor and equipped with a box-shaped cabin, used for carrying people or goods in multi-story buildings. It is a fixed lifting device that serves specified floors. It has a car that runs between at least two vertical rigid rails or with an inclination angle of less than 15°. It is convenient for passengers to enter and exit or load and unload goods.

[0003] When workers use a hanging basket to install guide rails in the elevator shaft, since the space in the elevator shaft is closed and lacks light, they need to use lighting devices to illuminate the elevator shaft. In the prior art, lighting lamps, such as LED lamps, are often installed on the working hanging basket to illuminate a large area; at the same time, they are used in conjunction with headlights to illuminate a small area to provide workers with a clear enough field of vision. Since the installation of the guide rails requires the use of a large number of bolts, drilling bolt holes with an electric drill in the elevator shaft will generate a lot of dust and debris. Some of the dust and debris will fall on the lighting device, affecting the lighting effect. Since the existing commonly used lighting lamps have blind spots, it is impossible to completely remove the dust and debris by manual wiping, which affects the lighting effect. Utility Model Content

[0004] The utility model aims to provide an elevator installation lighting device which is convenient for quick dust cleaning. A brush is arranged on one side of the lamp tube, and the lamp tube can rotate relative to the brush. When the lamp tube rotates, friction is formed with the brush, so that dust and debris on the lamp tube are cleaned without dead angles, and the cleaning effect is good, thereby ensuring normal lighting of the lighting device.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lighting device for elevator installation that is easy to clean quickly, comprising a lamp tube, a first lamp tube holder and a rotating shaft seat, one side of the lamp tube is rotatably set on the first lamp tube holder, a conductive sheet electrically connected to the positive and negative poles of the lamp tube is provided at the lamp head of the lamp tube, and two conductive ring sheets respectively in contact with the conductive sheets are also provided on the first lamp tube holder; the other side of the lamp tube is rotatably set on the rotating shaft seat; a brush is also provided on one side of the lamp tube.

[0006] Preferably, the first lamp holder is provided with a first plug hole rotatably matched with the lamp, and the two conductive ring pieces are coaxially arranged at the bottom of the first plug hole.

[0007] Preferably, a limiting portion for limiting the maximum insertion depth of the lamp tube is further provided in the first insertion hole.

[0008] Preferably, a second lamp tube holder is rotatably arranged on the rotating shaft seat, and the second lamp tube holder is provided with a second plugging hole for fixedly plugging an end of the lamp tube away from the first lamp tube holder.

[0009] Preferably, the suspended end of the second lamp holder is provided with a screwing ear.

[0010] Preferably, the brush is arranged on the lower side of the lamp tube.

[0011] Preferably, a sponge brush is provided in the middle of the brush and along the extension direction of the lamp tube.

[0012] Preferably, a clamp is provided at the bottom of the first lamp tube holder and the bottom of the rotating shaft holder respectively.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, a brush is arranged on one side of the lamp tube, and the lamp tube can rotate relative to the brush. When the lamp tube rotates, friction is formed with the brush, so that dust and debris on the lamp tube can be cleaned without dead angles, and the cleaning effect is good, ensuring that the lighting device can always maintain a good lighting state.

[0015] 2. The utility model can keep the lamp stably powered on and emitting light while the lamp is rotating, which is convenient for cleaning dust and debris during operation.

[0016] 3. The utility model uses a brush and a sponge brush to double clean dust and debris, thereby enhancing the cleaning effect. There are gaps between the bristles of the brush, which facilitates the shaking off of the initially cleaned dust and debris, reduces the accumulation of dust and debris on the sponge brush, and indirectly ensures the lighting effect.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] like Figure 1-Figure 9 As shown, a lighting device for elevator installation that is easy to clean quickly includes a lamp tube 1, a first lamp tube holder 2 and a rotating shaft seat 34. One side of the lamp tube 1 is rotatably set on the first lamp tube holder 2, and a conductive sheet 11 electrically connected to the positive and negative poles of the lamp tube 1 is provided at the lamp head of the lamp tube 1. Two conductive ring sheets 23 respectively contacting the conductive sheet 11 are also provided on the first lamp tube holder 2; the other side of the lamp tube 1 is rotatably set on the rotating shaft seat 34; a brush 6 is also provided on one side of the lamp tube 1.

[0036] As a specific embodiment, the first lamp holder 2 is provided with a first plug hole 21 that is rotatably matched with the lamp tube 1, and the two conductive ring pieces 23 are coaxially arranged at the bottom of the first plug hole 21. After the side of the lamp tube 1 with the conductive piece 11 is inserted into the first plug hole 21, the two conductive pieces 11 are respectively in contact with the corresponding conductive ring pieces 23, and the conductive ring pieces are electrically connected to the external power supply through the conductive wire 5, providing power to the lamp tube 1 and making the lamp tube light up. In this way, when the lamp tube 1 is rotated, the two conductive pieces 11 can always be in contact with the conductive ring piece 23 and stably provide power to the lamp tube 1, and friction occurs between the lamp tube 1 and the brush 6 when the lamp tube 1 rotates, and the brush 6 sweeps away the dust and debris on the lamp tube 1.

[0037] In this embodiment, the conductive sheet 11 and the conductive ring sheet 23 are set to the same material according to the positive and negative electrode materials of the lamp tube 1 to ensure the stability of their conductive performance. For example, the positive and negative electrodes of the lamp tube 1 are made of copper material, and the conductive sheet 11 is also made of copper material accordingly, and is respectively connected to the positive and negative electrodes of the lamp tube 1 by copper welding. The two conductive sheets 11 are electrically connected to the external power supply through the conductive wire 5. For example, a battery is provided on the working hanging basket to provide power for the lamp tube 1. How to electrically connect to the battery through the conductive wire belongs to the existing conventional technology, and its specific implementation method will not be described in detail here.

[0038] Specifically in the present embodiment, a limiting portion 22 for limiting the maximum insertion depth of the lamp tube 1 is further provided in the first insertion hole 21. The setting length of the limiting portion 22 is slightly smaller than the length of the conductive sheet 11. Under the premise of ensuring that the conductive sheet 1 can stably contact with the conductive ring sheet 23, the lamp tube 1 is prevented from being inserted too deeply, causing the conductive sheet 11 to undergo irreversible deformation.

[0039] As a specific implementation, the second lamp holder 3 is rotatably arranged on the rotating shaft seat 34, and the second lamp holder 3 is provided with a second plug hole 31 for fixedly plugging the end of the lamp tube 1 away from the first lamp holder 2. Specifically in this embodiment, the suspended end of the lamp tube 1 is provided with a limit plug 12 protruding outward, and the rotating shaft seat 34 is provided with a limit hole 32 matched with the limit plug 12 at the bottom of the second plug hole 31. The limit hole 32 limits the limit plug 12, thereby preventing the lamp tube 1 from slipping in the second plug hole 31, and the lamp tube 1 is driven to rotate when the second lamp holder 3 is rotated.

[0040] Furthermore, in order to facilitate the rotation of the lamp tube 1 , a screwing ear 33 is provided at the suspended end of the second lamp tube holder 3 .

[0041] Preferably, the brush 6 is arranged on the lower side of the lamp tube 1 to prevent the brush 6 from affecting the lamp tube 1 from normally illuminating the shaft wall of the elevator shaft and the working basket.

[0042] Furthermore, if Figure 8 As shown, a sponge brush 62 is provided in the middle of the brush 6 and along the extension direction of the lamp tube 1. The sponge brush 62 can clean the lamp tube 1 more carefully than the brush 6. Therefore, when the lamp tube 1 is rotated, the brush 6 is used for preliminary cleaning. When the lamp tube 1 is rotated to the part where the sponge brush 61 is located, the lamp tube 1 is further cleaned. Since there are gaps between the bristles of the brush 6, the dust and debris that are initially cleaned can be shaken off, and the accumulation of dust and debris on the sponge brush 62 can be reduced.

[0043] Specifically, in the present embodiment, a fixing seat 24 is disposed below the first lamp holder 2 , a connecting seat 61 is disposed below the brush 6 , and the rotating shaft seat 34 is transitionally connected to the fixing seat 24 via the connecting seat 61 .

[0044] Specifically, in the present embodiment, the bottom of the first lamp holder 2 and the bottom of the rotating shaft holder 34 are respectively provided with clamps 7 , and the entire device is fixed to the working hanging basket 4 through the clamps 7 .

[0045] Working principle: When in use, the device is fixed on the working hanging basket 4 by the clamp 7, and connected to the external power supply, such as a battery, through the conductive wire 5. A control switch can also be set on the conductive wire 5 according to actual needs.

[0046] When the operator is working in the elevator shaft, the elevator shaft around the working hanging basket 4 can be illuminated by energizing the lamp tube 1. When the worker is working, a lot of dust will be generated when drilling holes and installing the elevator guide rails using working tools such as electric drills. Therefore, no matter what kind of lighting device is used, dust and debris will fall on the lighting device. Long-term dust accumulation will affect the lighting effect. When cleaning the dust and debris on the lamp tube 1, the lamp tube 1 is driven to rotate by pinching and rotating the screw ear 33. During the rotation process, the lamp tube 1 rubs against the brush 6 and the sponge brush 62 to clean the dust and debris accumulated on the lamp tube 1. During the rotation of the lamp tube 1, the conductive sheet 11 is in stable contact with the conductive ring sheet 23. Under the premise of ensuring that the lamp tube 1 is stably powered on and illuminated, it can be rotated and dust can be cleaned.

[0047] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
