Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and in particular to a telescopic rod for testing fire-fighting facilities. Background Technology

[0002] High-altitude electrical testing requires personnel to climb to great heights to use instruments for testing, which is time-consuming and laborious, and cannot guarantee the personal safety of the personnel. Nowadays, there are testing poles for high-altitude electrical testing. The existing testing poles include a pole body with a testing head installed on the pole body. During testing, the testing instrument is connected to the pole body, and the conductivity of the testing head is used to conduct electricity into the testing instrument to observe whether there is leakage, etc.

[0003] For example, patent application number CN201721539723.4 discloses a fire detection telescopic pole for buildings. This pole includes a handle with anti-slip textured surfaces on one side. A control switch is fixedly installed on one side of the handle, and a support frame is fixedly installed on the other side. This fire detection telescopic pole can effectively detect and observe fires in complex environments within buildings. However, because the detection head is often a single-head design, it is often difficult to effectively untangle tangled wires within the detection area, thus affecting the safety of subsequent wire inspections.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a fire protection facility detection telescopic pole, including a lower pole body 1 and an upper pole body 3. The other end of the lower pole body 1 is provided with a telescopic handle 2, one end of the upper pole body 3 is provided with a pole head 7, and the other end of the upper pole body 3 is provided with a second connecting member 5. The second connecting member 5 is hinged to the first connecting member 4 through a pivot. The first connecting member 4 is provided with a buckle structure for limiting the second connecting member 5.

[0023] The detection rod adopts a folding design. When carrying it, the locking structure of the first connecting piece 4 and the second connecting piece 5 can be released, and the upper rod 3 can be straightened to one side of the lower rod 1, saving space and making it convenient for people to carry. After unfolding, the first connecting piece 4 and the second connecting piece 5 can be fixed with the buckle structure.

[0024] A storage groove 11 is provided at the end of the rod head 7 away from the upper rod body 3. A movable block 8 is provided in the storage groove 11. One end of the movable block 8 extends outside the storage groove 11. A Y-shaped fork 10 is provided at the end of the movable block 8 inside the storage groove 11. A detection head 9 is provided at the end of the movable block 8 extending outside the storage groove 11.

[0025] The lines drawn from 1 and connected through 8 and 9 are tested. The lines introduced into 11 should have a certain margin to support the rotation of 8.

[0026] The movable block 8 is rotatably connected to the upper rod 3 via a pivot, and the outer side of the upper rod 3 is provided with a positioning pin structure to limit the rotation of the movable block 8.

[0027] When encountering a problem of multiple tangled lines, the locking mechanism of the locating pin can be released from the movable block 8. Then, the movable block 8 can be rotated to pull the Y-shaped fork 10 out of the storage slot 11. The Y-shaped fork 10 can be used to separate the tangled lines, thus facilitating subsequent maintenance. The pin positioning method facilitates the switching between the detection head 9 and the Y-shaped fork 10 on the movable block 8.

[0028] It is worth explaining in detail that the first connecting piece 4 is fixedly connected to the lower rod body 1, and the second connecting piece 5 is fixedly connected to the upper rod body 3. A telescopic handle 2 is provided at the end of the lower rod body 1 away from the first connecting piece 4. The telescopic handle 2 serves to facilitate gripping and also allows adjustment of the length of the lower rod body 1 by pulling it. Specifically, one end of the telescopic handle 2 is inserted into the lower rod body 1 and slidably connected to it. A latching hole is provided on the outer side of the telescopic handle 2, and an elastic retaining ball is provided on the inner side of the lower rod body 1 to engage with the latching hole. When the telescopic handle 2 is pulled, the elastic retaining ball on the inner side of the lower rod body 1 engages in the latching hole on the outer side of the telescopic handle 2, limiting its position. Since this is widely used in existing products, further explanation is not provided here.

[0029] Regarding the positioning pin structure:

[0030] The positioning pin structure includes a positioning bolt 18, which passes through the upper rod body 3 and is threadedly connected to it. Positioning holes 19, threaded into the positioning bolt 18, are provided at both ends of the movable block 8. When the detection head 9 is rotated and retracted into the receiving slot 11, one of the positioning holes 19 on the movable block 8 will coincide with the axis of the positioning bolt 18. The positioning bolt 18 is then screwed into it, thus fixing the movable block 8. When switching the Y-shaped fork 10, rotating the movable block 8 causes it to rotate 180°, coinciding with the axis of the other positioning hole 19 on the movable block 8. Screwing it into this hole then fixes the switched Y-shaped fork 10.

[0031] It is worth explaining in detail that a check baffle 6 is provided at the end of the first connecting member 4 near the second connecting member 5. The check baffle 6 is fixedly connected to the first connecting member 4 and engages with the second connecting member 5. The second connecting member 5 is hinged to the first connecting member 4 via a pivot. The check baffle 6 is fixed to the side of the first connecting member 4 away from the pivot. By limiting the second connecting member 5, the lower rod 1 and the upper rod 3 are kept in a horizontal and vertical state.

[0032] Regarding the snap-fit ​​structure:

[0033] The latching structure includes a latch 12 located on the outside of the second connecting member 5. The latch 12 is fixedly connected to the second connecting member 5 and engages with a latch groove 13 formed on the check baffle 6. After the lower rod 1 and the upper rod 3 are extended, the second connecting member 5 will retract to one side of the check baffle 6, and the latch 12 on the second connecting member 5 will engage with the latch groove 13 formed on the check baffle 6. The latch groove 13 limits the second connecting member 5 by cooperating with the latch 12.

[0034] To prevent the snap-fit ​​connection between the second connector 5 and the check baffle 6 from failing due to lateral impact during use, thus affecting the safety of the detection rod, in a preferred embodiment, a positioning pin 14 is provided on the outer side of the second connector 5. The positioning pin 14 is fixedly connected to the second connector 5, and the positioning pin 14 is slidably connected to the pin hole 15 opened on the outer side of the check baffle 6. A limit bolt 17 is fitted on the positioning pin 14, and the limit bolt 17 is threadedly connected to the connecting hole 16 opened on the outer side of the positioning pin 14. The connecting hole 16 is located on the side of the positioning pin 14. When the lower rod body 1 and the upper rod body 3 are unfolded, and the buckle 12 on the upper rod body 3 engages with the buckle groove 13 on the check baffle 6, the positioning pin 14 on the outer side of the upper rod body 3 will also engage with the pin hole 15 on the outer side of the check baffle 6. By screwing the limit bolt 17 into the connecting hole 16 on the positioning pin 14, the limit bolt 17 can limit the positioning pin 14, preventing the second connecting piece 5 from disengaging from the check baffle 6 and improving the safety of the detection rod.

[0035] How this application works:

[0036] The testing rod features a folding design. By releasing the locking mechanism on the first connecting piece 4 and the second connecting piece 5, the upper rod 3 can be straightened to one side of the lower rod 1, saving space and making it easier to carry. Once unfolded, the first connecting piece 4 and the second connecting piece 5 can be secured using the snap-fit ​​mechanism. When encountering tangled wires, after releasing the locking mechanism on the movable block 8, rotating the movable block 8 allows the Y-shaped fork 10 to be pulled out of the storage slot 11. The Y-shaped fork 10 can then be used to untangle the tangled wires, facilitating subsequent maintenance.
