Description

Technical Field

[0001] The utility model belongs to the field of fire hose installation equipment, and specifically provides a joint tightening device with an indication structure. Background Art

[0002] The connection between the existing fire hose and the metal joint is generally tightened in advance by a special device. However, in actual fire fighting work, when the hose needs to be maintained and extended, it can only rely on firefighters to reassemble the hose and the joint on-site.

[0003] In order to quickly tighten and connect the fire hose and the metal joint, firefighters will use a joint tightening device to tighten the two. However, this device generally uses hydraulic power to push the extrusion shaft in the oil cylinder to tighten the locking mechanism inside the hose. Therefore, it is necessary to ensure that the joint of the hose is installed in place with the tightening device before the hose is tightened. Otherwise, problems such as incomplete tightening and water leakage may occur. Moreover, when the tightening device is working, the oil cylinder pressure can often reach more than 10 MPa, and improper installation is also prone to safety accidents. In actual fire fighting operations, due to environmental or other factors, firefighters are highly tense and prone to misoperations. For example, starting to install and tighten the hose joint when the joint and the tightening device are not installed in place, resulting in dangerous accidents. Therefore, there is an urgent need for a safer joint tightening device. Summary of the Utility Model

[0004] The utility model provides a joint tightening device with an indication structure, which reminds firefighters of the working state of the device through the indication structure, ensuring that firefighters can quickly operate the device to tighten the joint and reducing the occurrence of accidents.

[0005] The technical solution of the utility model is as follows:

[0006] A joint tightening device with an indication structure includes a device body, and an indicator light assembly is arranged on the device body. The indicator light assembly emits lights of different colors according to the working state of the device body.

[0007] Preferably, the device body includes a frame, a driving unit is arranged on the frame, a tightening structure is arranged on the frame, and the driving unit drives the tightening shaft of the tightening structure to move axially to perform the joint tightening action. The indicator light assembly is arranged at the tightening structure.

[0008] In this solution, the indicator light assembly indicates different states when the hose joint is tightened through lights of different colors. The light color of each state is specific. Firefighters can quickly judge the state of the joint according to the color indication and take corresponding measures, which can effectively improve the installation efficiency of the fire hose in actual fire fighting work and also greatly avoid the occurrence of dangerous situations during the installation and tightening process.

[0009] Preferably, the indicator light assembly includes an LED lamp group and a light-transmitting panel. A control circuit board is provided in the LED lamp group, and a microcontroller is provided on the control circuit board. The LED lamp group is electrically connected to the main switch of the device. When the main switch of the joint tightening device is activated, the LED lamp group is powered on to work and emits color A light.

[0010] In this solution, the LED lamp group can be equipped with its own battery or connected to the power supply of the joint tightening device. The power supply of the joint tightening device can be externally connected to the mains through a plug or use a storage battery. When the device is started, the LED lamp group is powered on to work and emits light, indicating the position of the tightening structure, so that firefighters can find the position of the tightening structure at a glance and quickly install the hose joint. At the same time, in forest fire fighting, the fire is often large and the smoke is thick. When it is necessary to extend the water pipe to install the hose and joint in the middle and late stages of the fire fighting work, because this structure makes the LED lamp group of the joint tightening device emit a constant color A light, and color A is preferably red, so that firefighters can easily find the equipment and the tightening structure station, avoiding delaying the rescue time. At the same time, the constantly lit color A can also indicate the safe direction for firefighters in the thick smoke.

[0011] Preferably, an induction switch is provided in the tightening structure. The induction switch is electrically connected to the control circuit board. When a hose joint is installed on the tightening structure, the induction switch is turned on and generates an electrical signal to make the LED lamp group emit light.

[0012] In this solution, only when the hose joint is completely attached to the tightening structure can the induction switch be triggered to make the LED lamp group emit light, indicating that the connection between the hose joint and the tightening structure is in place at this time, and subsequent tightening work can be carried out safely, effectively reducing the occurrence of safety accidents.

[0013] Preferably, a plurality of induction switches are provided. The induction switches are evenly arranged in a circumferential manner around the axis of the tightening structure. When not all of the induction switches are turned on, the LED lamp group emits color C light; when all of the induction switches are turned on, the LED lamp group emits color B light.

[0014] In this solution, in order to further prevent firefighters from not connecting the hose joint and the tightening structure properly when installing the hose joint, that is, to prevent the axis of the hose joint from not coinciding with the axis of the tightening structure, and there are gaps in some areas where they are not in contact. In this case, only some of the induction switches will be triggered, so the LED lamp group emits color C light, reminding firefighters that the hose joint is not connected properly and avoiding the occurrence of safety accidents. Color C is preferably yellow; and only when the axis of the hose joint coincides with the axis of the tightening structure, that is, when the hose joint and the tightening structure are connected in place and all the induction switches are turned on, the LED lamp group will emit color B light. Color B is preferably green, indicating that the hose joint has been installed in place and the next step can be carried out.

[0015] Preferably, the control circuit board is electrically connected to the driving unit of the joint tightening device, and the driving unit generates an electrical signal to turn on the LED lamp group in color D.

[0016] In this solution, before the driving unit runs, the LED lamp group must be lit in green. When the driving unit runs, that is, when the joint tightening device starts to tighten the water hose and the hose joint, at this time, the color of the LED lamp group is changed to color D, preferably blue, indicating that the device is working, so as to prompt the waiting firefighters. When the tightening is completed, the driving unit stops, and the LED lamp group lights up in color B again, prompting the firefighters again that the tightening is completed.

[0017] Preferably, the indicator light assembly is of an annular structure, the indicator light assembly is arranged around the tightening structure, and the LEDs are evenly arranged in the indicator light assembly.

[0018] Preferably, the inductive switch is a proximity switch.

[0019] Preferably, a wheel set structure is provided at the bottom of the frame.

[0020] Advantages of the present utility model:

[0021] By providing a joint tightening device with LED lamp indication, the present utility model indicates different states of the hose joint during connection and tightening through LEDs of different colors. The color of the LED for each state is specific. Firefighters can quickly judge the state of the joint according to the color indication and take corresponding measures. The LED lamp indication can also enable firefighters to always know whether their operations are qualified, which can greatly avoid the occurrence of accidents and effectively improve the installation efficiency of fire hoses in actual fire fighting work.

[0028] In combination with the drawings, through the specific implementation mode of the embodiments of the present invention, the technical solutions of the present invention will be clearly and completely described.

[0029] The technical solution of the present utility model is as follows:

[0030] As Figure 1 And to Figure 3 shown, a joint tightening device with an indicating structure includes a device body. An indicator light assembly 1 is provided on the device body, and the indicator light assembly 1 lights up lights of different colors according to the working state of the device body.

[0031] Furthermore, the device body includes a frame 3. A driving unit 32 is provided on the frame 3, and a tightening structure 31 is provided on the frame 3. The driving unit 32 drives the tightening shaft 33 of the tightening structure 31 to move axially to perform the joint tightening action. The indicator light assembly 1 is provided at the tightening structure 31.

[0032] Specifically, by setting a joint tightening device with an indicating structure with LED lamp indication, different states during the connection of the hose joint are indicated by LEDs of different colors. The color of the LED for each state is specific. Firefighters can quickly judge the state of the joint according to the color indication and take corresponding measures. The LED indication can also enable firefighters to always know whether their operations are qualified, which can greatly avoid the occurrence of accidents and effectively improve the installation efficiency of fire hoses in actual fire fighting work.

[0033] Embodiment 1:

[0034] The indicator light assembly 1 includes an LED lamp group 11 and a light-transmitting panel 12. A control circuit board is provided in the LED lamp group 11, and a microcontroller is provided on the control circuit board. The LED lamp group 11 is electrically connected to the main switch of the device. When the main switch of the joint tightening device is started, the LED lamp group 11 is powered on and lights up in color A. Furthermore, the LED lamp group 11 includes a control circuit board, and a microcontroller is provided on the control circuit board. The microcontroller is electrically connected to an LED lamp. The LED lamp group 11 is electrically connected to the main switch of the joint tightening device. When the main switch of the joint tightening device is started, the LED lamp group 11 is powered on and the LED lamp lights up in color A.

[0035] Specifically, the LED light group 11 can be a power source with a built-in battery or a power supply connected to the joint tightening device. The microcontroller can be programmed and controlled using Arduino or a PLC board. When the device is started, the LED light group 11 is powered on and lights up to indicate the position of the tightening structure 31, enabling firefighters to quickly locate the position of the tightening structure 31 at a glance and install the hose joint 4 quickly. Especially in forest fire fighting, the fire is often large and the smoke is thick. When it is necessary to extend the water pipe to install the hose and joint in the later stage of the fire fighting work, since this structure makes the LED light of the joint tightening device constantly shine in color A, and color A is preferably a conspicuous color such as red, it enables firefighters to easily find the device and the working position of the tightening structure 31, avoiding delaying the rescue time. At the same time, the constantly shining color A can also indicate the safe direction for firefighters in the thick smoke.

[0036] Further, the induction switch 2 is a proximity switch, or a travel switch, or a distance sensor can also be used to ensure that when the switch is turned on, the tightening structure 31 and the hose joint 4 at the switch are in contact with each other.

[0037] Further, the indicator light assembly 1 is of an annular structure, the indicator light assembly 1 is arranged around the tightening structure 31, and the LED lights are evenly arranged in the indicator light assembly 1. Surrounding the tightening structure 31 can more clearly indicate the position here.

[0038] Embodiment 2:

[0039] On the basis of Embodiment 1, the connection state of the hose joint 4 and various working states of the device also need to be indicated. For this purpose, the LED light group 11 is electrically connected to an induction switch 2, and the induction switch 2 is arranged on the contact surface between the tightening structure 31 and the hose joint 4. When the hose joint 4 is installed on the tightening structure 31, the induction switch 2 generates an electrical signal to make the LED light group 11 emit light.

[0040] Specifically, an indicator light assembly 1 provided with an LED light group 11 is installed on the existing joint tightening device. Only when the hose joint 4 is completely attached to the tightening structure 31 can the induction switch 2 be triggered to make the LED light group 11 emit light, indicating that the connection between the hose joint 4 and the tightening structure 31 is in place at this time, and subsequent tightening work can be carried out safely, effectively reducing the occurrence of safety accidents.

[0041] Further, a plurality of induction switches 2 are provided, and the induction switches 2 are evenly arranged in a circumferential manner around the axis of the tightening structure 31.

[0042] Furthermore, when not all of the induction switches 2 are turned on, the LED lights shine in color C; when all of the induction switches 2 are turned on, the LED lights shine in color B.

[0043] Specifically, to prevent firefighters from failing to properly connect the hose joint 4 to the expansion structure 31 when installing it, that is, to prevent the axis of the hose joint 4 from not coinciding with the axis of the expansion structure 31, and there are gaps in some areas where they do not come into contact properly, safety accidents are extremely likely to occur in such cases. However, when this happens, only some of the induction switches 2 will be triggered. Therefore, at this time, the control circuit board controls the LED light to turn on color C, reminding the firefighters that the hose joint 4 is not properly connected and avoiding the occurrence of safety accidents. Color C is preferably yellow; and only when the axis of the hose joint 4 coincides with the axis of the expansion structure 31, that is, when the hose joint 4 and the expansion structure 31 are properly connected and all the induction switches 2 are turned on, the LED light will turn on color B. Color B is preferably green, indicating that the hose joint 4 has been installed in place and the next step can be taken.

[0044] Furthermore, the control circuit board is electrically connected to the driving unit 32 of the joint tightening device, and the driving unit 32 generates an electrical signal when it operates to make the LED light turn on color D.

[0045] Specifically, before the driving unit 32 operates, the LED light group 11 must turn on green. When the driving unit 32 operates, that is, when the joint tightening device starts to tighten the hose and the hose joint 4, at this time, the color of the LED light is changed to color D, preferably blue, indicating that the device is working, so as to prompt the waiting firefighters. After the tightening is completed, the driving unit 32 stops, and the LED light turns on color B again, prompting the firefighters again that the tightening is completed.

[0046] It should be noted that the above colors such as A, B, C, etc. are only the preferred ways to distinguish different operating conditions of the device, and it is also possible to distinguish them by changing the flashing frequency of the light, color interaction, etc.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present invention.
