DETAILED DESCRIPTION
[0045] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0046] Please also refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 7 The lighting tool for monitoring and inspection provided by the present invention is now described. The lighting tool for monitoring and inspection includes a battery cartridge 1, a power supply battery 2, a plastic bag 3, a connecting shaft 4, a lighting lamp 5, an air intake pipe 6, and a first one-way valve 7. The power supply battery 2 is fixedly mounted within the battery cartridge 1.
[0047] The plastic bag 3 is in an elongated shape with open ends at both ends. A first end of the plastic bag 3 is fixedly connected to the battery can 1 and communicates with the interior of the battery can 1 .
[0048] One section of the connecting shaft 4 passes through the second end of the plastic bag 3 and is arranged in the plastic bag 3 . The connecting shaft 4 and the plastic bag 3 are circumferentially sealed and fixedly connected.
[0049] The lighting lamp 5 is fixedly connected to the connecting shaft 4 and electrically connected to the power supply battery 2 .
[0050] The air inlet pipe 6 is fixed on the battery can 1 and communicates with the inside of the battery can 1 .
[0051] The first one-way valve 7 is provided on the air intake pipe 6 .
[0052] Compared with the prior art, the lighting tool for supervision and inspection provided by the present invention is different from the prior art. When the lighting tool needs to be inserted into a narrow space, air is blown into the battery canister 1 through the air inlet pipe 6, and the gas entering the battery canister 1 enters the plastic bag 3 connected to the battery canister 1, thereby causing the plastic bag 3 to swell. Since the plastic bag 3 is in the shape of an elongated strip, the lighting lamp 5 on the connecting shaft 4 at the second end of the plastic bag 3 can be inserted into the narrow space for lighting, thereby avoiding the problem that the existing lighting tools are short in size and cannot be inserted into some narrow spaces for lighting.
[0053] In this embodiment, the power supply battery 2 supplies power to the lighting lamp 5 electrically connected thereto.
[0054] The first one-way valve 7 can prevent the gas entering the battery can 1 from flowing out from the air inlet pipe 6 .
[0055] Since the inflated plastic bag 3 also has a certain degree of deformation ability, it can pass through some narrow spaces with complex structures through deformation.
[0056] In some embodiments, see Figures 2 to 4 The battery can 1 is provided with a connecting hole 111 connected to the first end of the plastic bag 3, a section of the lighting lamp 5 is embedded in the connecting shaft 4, and the lighting tool for supervision and detection also includes a connecting wire 8.
[0057] The middle portion of the connecting wire 8 passes through the plastic bag 3 and the communicating hole 111 , one end of the connecting wire is located in the battery can 1 and electrically connected to the power supply battery 2 , and the other end of the connecting wire is fixed in the connecting shaft 4 and electrically connected to the lighting lamp 5 .
[0058] The connecting wire 8 is passed through the plastic bag 3 , thereby preventing the connecting wire 8 from taking up extra space and preventing the connecting wire 8 and the plastic bag 3 from being entangled with each other.
[0059] In this embodiment, the end of the lighting lamp 5 used for lighting is located outside the connecting shaft 4 .
[0060] In some embodiments, see Figure 5 and Figure 7 The battery tube 1 is arranged in a split body, including a tube body 11 with an open end at one end and a tube cover 12 detachably connected to the tube body 11. The communicating hole 111 is located on the end surface of the other end of the tube body 11. The tube cover 12 closes the open end of the tube body 11. The power supply battery 2 is fixed on the tube cover 12 and has an inflation gap 13 with a U-shaped longitudinal section between it and the inner wall of the tube body 11. The air inlet pipe 6 is fixed on the tube cover 12 and is connected to the inflation gap 13.
[0061] After the lighting tool has finished lighting a narrow space, the connection between the tube cover 12 and the tube body 11 is disconnected to release the gas in the plastic bag 3, thereby making the lighting tool easy to carry.
[0062] In some embodiments, see Figures 2 to 4 The diameter of the section of the connecting shaft 4 located outside the plastic bag 3 is larger than the diameter of the section of the connecting shaft 4 located inside the plastic bag 3. The section of the connecting shaft 4 located outside the plastic bag 3 is provided with a first external thread, and the outer wall of the cylinder 11 is provided with a second external thread. The lighting tool used for supervision and detection also includes a connecting cylinder 9.
[0063] One end of the connecting tube 9 is open, and the end surface of the other end is provided with a first threaded hole 91. The connecting tube 9 is sleeved on the outside of the battery tube 1 and has a first internal thread that is threadedly connected to the second external thread. The plastic bag 3 passes through the first threaded hole 91.
[0064] The section of the connecting shaft 4 located outside the plastic bag 3 can be inserted into the first threaded hole 91 and the first external thread is threadedly connected to the first threaded hole 91 .
[0065] When the plastic bag 3 is deflated, the plastic bag 3 is completely inserted into the connecting tube 9 through the first threaded hole 91, and the section of the connecting shaft 4 located outside the plastic bag 3 is inserted into the first threaded hole 91 and the first external thread is threadedly connected to the first threaded hole 91. This makes it convenient to carry and the plastic bag 3 can be protected by the connecting tube 9.
[0066] In some embodiments, see Figure 2 and Figure 5 The lighting tool for supervision and detection also includes an air pump 10, a first connecting pipe 110, a sliding plate 120, a sealing gasket 130 and a push shaft 140.
[0067] The air pump 10 is located on a side of the air inlet pipe 6 away from the battery can 1 and is coaxially arranged with the battery can 1 . The end of the air pump 10 away from the air inlet pipe 6 is an open end.
[0068] The first connecting tube 110 is fixed on the end surface of the air pump 10 facing the air inlet pipe 6 and is communicated with the interior of the air pump 10 . The first connecting tube 110 is slidably sleeved on the air inlet pipe 6 .
[0069] The sliding plate 120 is slidably disposed in the air pump 10 .
[0070] The sealing gasket 130 is located inside the air pump 10 and on a side of the sliding plate 120 facing the first connecting tube 110 . The sealing gasket 130 is fixedly fitted to the sliding plate 120 and circumferentially fitted to the inner wall of the air pump 10 .
[0071] The push shaft 140 is coaxially arranged with the air pump 10 . The push shaft 140 passes through the open end of the air pump 10 . One end of the push shaft 140 located inside the air pump 10 is fixedly connected to the sliding plate 120 .
[0072] The sliding plate 120 is pushed by the push shaft 140 to slide toward the first connecting tube 110, thereby inflating the air into the air intake pipe 6. After one inflation is completed, the first connecting tube 110 can be slid off the air intake pipe 6, and then the push shaft 140 is moved a distance away from the first connecting tube 110, and then the first connecting tube 110 is slidably mounted on the air intake pipe 6, and air is inflated into the air intake pipe 6 again, and the above operation is repeated until enough gas is filled into the plastic bag 3.
[0073] The sealing gasket 130 can ensure sealing between the sliding plate 120 and the inner wall of the air pump 10 .
[0074] In some embodiments, see Figure 7 A second internal thread is provided in the cylinder body 11, and a section of the cylinder cover 12 is passed through the cylinder body 11 and is provided with a third external thread threadedly connected to the second internal thread.
[0075] The cylinder cover 12 is detachably connected to the cylinder body 11 by threaded connection between the second internal thread and the third external thread.
[0076] In this embodiment, both the second internal thread and the third external thread are sealing threads.
[0077] In some embodiments, see Figure 5 The lighting tool for supervision and detection also includes a fixed tube 150.
[0078] The fixed pipe 150 is parallel to the air inlet pipe 6 and is fixedly connected to the cylinder cover 12 .
[0079] It is convenient to rotate the cylinder cover 12 through the fixing pipe 150 and the air inlet pipe 6 , that is, it is convenient to remove or install the cylinder cover 12 from the cylinder body 11 .
[0080] In some embodiments, see Figure 5 and Figure 7 The cylinder cover 12 is provided with a long strip groove 121 on the end surface outside the cylinder body 11. One end of the fixing tube 150 is located in the long strip groove 121 and there is an air intake gap 1211 between the end and the bottom surface of the long strip groove 121. The lighting tool used for supervision and detection also includes a second one-way valve 160 and a second one-way valve 160.
[0081] The second one-way valve 160 is disposed on the fixed pipe 150 .
[0082] The second connecting tube 170 is slidably sleeved on the fixed tube 150 . The second connecting tube 170 is fixedly connected to the end surface of the air pump 10 facing the air inlet pipe 6 and is communicated with the interior of the air pump 10 .
[0083] After the air pump 10 has completed one inflation of the air intake pipe 6, the first connecting pipe 110 no longer needs to slide down the air intake pipe 6, and the push shaft 140 is directly moved away from the air intake pipe 6, so that the outside air enters the fixed pipe 150 through the air intake gap 1211, and then enters the air pump 10. When the air intake pipe 6 is inflated, the second one-way valve 160 allows the air in the air pump 10 to flow out of the air intake pipe 6.
[0084] In some embodiments, see Figure 5 The outer side walls of the air intake pipe 6 and the fixed pipe 150 respectively have a first protrusion 61 and a second protrusion 1501 protruding outward. The lighting tool for supervision and detection also includes a first sealing ring 180 and a second sealing ring 190.
[0085] The first sealing ring 180 is sleeved on the air intake pipe 6 and is located between the first protruding portion 61 and the first connecting pipe 110 .
[0086] The second sealing ring 190 is sleeved on the fixing tube 150 and is located between the second protruding portion 1501 and the second connecting tube 170 .
[0087] When the first connecting tube 110 presses the first sealing ring 180 toward the first protruding portion 61 , the second connecting tube 170 can press the second sealing ring 190 toward the second protruding portion 1501 .
[0088] When air is inflated into the intake pipe 6 , the first connecting pipe 110 squeezes the first sealing ring 180 to achieve sealing between the first connecting pipe 110 and the intake pipe 6 , and the second connecting pipe 170 squeezes the second sealing ring 190 to achieve sealing between the second connecting pipe 170 and the fixed pipe 150 .
[0089] In this embodiment, the first sealing ring 180 may be fixedly connected to the air intake pipe 6 , and the second sealing ring 190 may be fixedly connected to the fixed pipe 150 .
[0090] In some embodiments, see Figure 1 、 Figure 3 and Figure 6 The lighting tool for supervision and detection also includes a connecting ring 200.
[0091] The connecting ring 200 is sleeved on the push shaft 140 , and a fourth external thread is provided on the outer wall of the connecting ring 200 .
[0092] Among them, when one end of the connecting tube 9 used to open the first threaded hole 91 abuts against one end of the cylinder body 11 used to open the connecting hole 111, the connecting tube 9 is sleeved on the outside of the air pump 10, the connecting ring 200 can be inserted into the connecting tube 9 and the fourth external thread is threadedly connected to the first internal thread, so that the connecting ring 200 abuts against the air pump 10, thereby realizing that the first connecting tube 110 squeezes the first sealing ring 180 in the direction of the first protrusion 61 and the second connecting tube 170 squeezes the second sealing ring 190 in the direction of the second protrusion 1501.
[0093] The fourth external thread on the connecting ring 200 is threadedly connected to the first internal thread to connect the connecting ring 200 to the connecting tube 9, thereby indirectly connecting the connecting ring 200 to the air pump 10. The abutment between the connecting ring 200 and the air pump 10 ensures that the first connecting tube 110 remains in a state of pressing the first sealing ring 180 toward the first protrusion 61, and that the second connecting tube 170 remains in a state of pressing the second sealing ring 190 toward the second protrusion 1501.
[0094] After the inflation is completed, the push shaft 140 is slid outward from the air pump 10 , thereby further extending the length of the lighting tool so that it can be used in a longer narrow space.
[0095] After using the lighting tool, disconnect the threaded connection between the connecting ring 200 and the connecting tube 9. Then, rotate the connecting tube 9 to create a gap sufficient for placing the plastic bag 3 between the end of the connecting tube 9 defining the first threaded hole 91 and the end of the barrel 11 defining the communication hole 111. Then, slide the first connecting tube 110 off the air intake pipe 6 and the second connecting tube 170 off the fixing tube 150, separating the battery cartridge 1 and the air pump 10 for easier storage.
[0096] The side wall of the push shaft 140 has an outwardly protruding limiting portion 1401 . The limiting portion 1401 is located on a side of the connecting ring 200 away from the first connecting tube 110 , thereby limiting the connecting ring 200 from being separated from the push shaft 140 .
[0097] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
