Technical Field
[0001] The present application relates to the field of sensor fixing devices, and in particular to a sensor fixing device. Background Art
[0002] In sensor applications, the role of the fixing bracket cannot be ignored, as it directly affects the stability and measurement accuracy of the sensor. In aerosol fire extinguishing tests, sensors are required to detect oxygen concentration, fire extinguishing density, and temperature. Usually, a mounting bracket is set up in the test space, and the sensor is fixedly connected to the bracket.
[0003] However, existing sensor holder designs are still insufficient in some aspects. To enhance stability, many holders use heavy bases and complex support structures, resulting in a bulky overall size, which not only takes up valuable experimental space, but also may cause unnecessary interference to the experimental environment, thus affecting the experimental accuracy. Utility Model Content
[0004] In order to reduce the space occupied by the sensor tooling bracket in the experimental space, the present application provides a sensor fixing device.
[0005] The sensor fixing device provided in this application adopts the following technical solution:
[0006] A sensor fixing device comprises a cable and a connecting seat, wherein both ends of the cable can be connected to an experimental space, the connecting seat is connected to the cable, and the connecting seat is used to fix components such as sensors.
[0007] By adopting the above technical solution, the two ends of the cable are fixedly connected to the inner wall of the test space, so that the cable is stretched straight as the basis for installing the connecting seat, and then the required sensor is installed on the connecting seat. In this way, the cable is smaller in size than the bracket, which reduces the space occupied by the installation bracket, improves space utilization, and can also reduce the impact on the test environment, which is conducive to improving the detection angle.
[0008] Optionally, a hook is provided on the connecting seat, and the hook is used for the cable to be connected. A limit seat is movably provided on the connecting seat, and the limit seat can press the cable tightly into the hook. The connecting seat is provided with a limit device for limiting the movement of the limit seat.
[0009] By adopting the above technical solution, the hook is used for clamping the cable, and the limit seat can press the cable tightly in the hook to ensure the stable connection of the cable. The limit device limits the movement of the limit seat, further enhancing the stability and safety of the fixing frame.
[0010] Optionally, the pull rope has at least two strands, the hooks on the connecting seat are divided into two groups, and the openings of the two groups of hooks on the same connecting seat face opposite directions;
[0011] The limiting device includes a base, which is located between the two groups of hooks. The base is movably connected to the limiting seat through a connecting rod. A controller is provided on the connecting seat. The controller can control the movement of the base, and then drive the base to move closer to or away from the corresponding hook through the connecting rod.
[0012] By adopting the above technical solution, the controller controls the movement of the base, and the distance between the limit seat and the hook can be easily adjusted, thereby facilitating the tightening or loosening of the cable and facilitating the assembly and disassembly operations between the connecting seat and the cable.
[0013] Optionally, the controller includes a first threaded member disposed on the base, and the first threaded member can push the base to move, thereby driving the base to move closer to or away from the corresponding hook through the connecting rod.
[0014] By adopting the above technical solution and using a threaded member as a controller, the adjustment process is made more stable and reliable, and the moving distance of the base can be accurately controlled, thereby realizing the assembly and disassembly operations between the connecting seat and the cable.
[0015] Optionally, the end of the cable is fixed to the experimental space via a support plate, and an adjustment component for controlling the tensioning force of the cable is provided on the support plate.
[0016] By adopting the above technical solution, the support plate provides a stable fixing point for the cable, and the cable tensioning force can be adjusted through the adjustment component, so that the fixing frame can adapt to different tensioning force requirements and improve its scope of use.

[0021] Optionally, a sleeve is hinged on the locking hook, and the sleeve is sleeved on the second threaded member. An end plate is provided at one end of the second threaded member, and the end plate is used to limit the sleeve from detaching from the second threaded member.
[0022] By adopting the above technical solution, the design of the sleeve and the end plate ensures that the locking hook can be stably fixed on the second threaded member to prevent it from falling off or loosening during use, so that the cable can continue to maintain the tension effect.

DETAILED DESCRIPTION
[0032] The following is combined with Figure 1-3 This application is described in further detail.
[0033] The present application embodiment discloses a sensor fixing device. Figure 1 and Figure 2 The sensor tooling bracket includes a cable 1 and a connecting seat 11. Since the experiment needs to be carried out in a set space, a similar box is usually set up to simulate the actual situation for the experiment. Support plates 12 are provided at both ends of the cable 1, and the support plates 12 are connected to the inner wall of the experimental space. A hook 13 is provided on the connecting seat 11, and the cable 1 can be snapped into the slot 14 formed by the hook 13 and the connecting plate. A movable limit seat 15 is also provided on the connecting seat 11, and the connection method of the limit seat 15 on the connecting seat 11 can be a sliding connection or a hinged connection. The operator can operate the limit seat 15 to firmly press the cable 1 into the hook 13 to prevent it from loosening or falling off.
[0034] In order to enhance the connection stability between the connecting seat 11 and the cable 1, a limiting device 2 is provided on the connecting seat 11, and the limiting device 2 is used to limit the movement of the limiting seat 15, so that the limiting seat 15 and the hook 13 maintain a state of clamping the cable 1, thereby fixing the position of the connecting plate on the cable 1.
[0035] The limiting device 2 can be fixed by threaded parts such as screws or bolts, or it can be combined with some connecting rods 22 structures and threaded parts to control the position adjustment of the connecting seat 11, so as to fix the position of the limiting seat 15 and achieve the effect of tightening the cable 1 in the hook 13.
[0036] In order to increase the stability between the connection seat 11 and the cable 1 and to increase the installation stability of the sensor and other components, it is required that there are at least two strands of the cable 1 between the two support plates 12, and at least two hooks 13 on the connection seat 11. The hooks 13 arranged on the same connection seat 11 are divided into two groups, and the opening directions of the two groups of hooks 13 are opposite.
[0037] In the embodiment of the present application, the cable 1 is provided with two strands, and two hooks 13 are also provided on the same connecting seat 11. The limiting device 2 includes a base 21, and the base 21 is located between the two groups of hooks 13, that is, between the two hooks 13. The base 21 is movably connected to the limiting seat 15 through a connecting rod 22, and the limiting seat 15 is slidably provided on the connecting seat 11 along the opening direction of the hook 13, and the movement of the base 21 can drive the limiting seat 15 to approach or move away from the corresponding hook 13.
[0038] Specifically, one end of the connecting rod 22 may be hinged on the base 21, and the other end of the connecting rod 22 may be hinged on the lower limit seat 15. The ends of the two connecting rods 22 close to the base 21 are inclined in a direction away from the connecting seat 11. When the base 21 moves toward the direction close to the connecting seat 11, the two limit seats 15 are driven away from each other, and when the base 21 moves away from the connecting seat 11, the two connecting seats 11 are driven toward each other.
[0039] The base 21 is provided with a controller for controlling the base 21 to approach or move away from the connecting base 11, and the controller may be an electric push rod, a pin or a threaded member, etc. In the embodiment of the present application, the controller includes a first threaded member 23 provided on the base 21, and the first threaded member 23 may be a stud, a bolt or a nut, etc., and the first threaded member 23 can control the movement of the base 21, so that the limit seat 15 can move close to the hook 13, so that the limit seat 15 presses the zipper tightly against the hook 13.
[0040] The openings of the two groups of hooks 13 on the same connecting seat 11 can be arranged opposite to each other or opposite to each other.
[0041] When the openings of the two sets of hooks 13 on the same connecting seat 11 are arranged opposite to each other, the first threaded member 23 can be threadedly connected to the base 21 and rotatably connected to the connecting seat 11, or the first threaded member 23 can be rotatably connected to the base 21 and threadedly connected to the connecting seat 11. The first threaded member 23 is threadedly connected to the base 21 and rotatably connected to the connecting seat 11.
[0042] When the openings of the two sets of hooks 13 on the same connecting seat 11 are arranged opposite to each other, the first threaded member 23 is threadedly connected to the base 21 , and the end of the first threaded member 23 can abut the connecting seat 11 and push the base 21 and the connecting seat 11 away from each other.
[0043] like Figure 1 and Figure 3 The cable 1 is provided with two strands, and the ends of the two strands of the cable 1 are connected to the corresponding support plate 12 to achieve the fixation of the cable 1 in the experimental space. The support plate 12 is provided with an adjustment component for adjusting the tightness of the cable 1, and the adjustment component includes an adjustment frame 3 fixedly connected to the support plate 12, and a second threaded member 35 is threadedly connected to the adjustment frame 3. The second threaded member 35 can be, for example, a stud, a bolt or a nut, and a lock hook 31 for pulling the cable 1 is provided on the second threaded member 35. A sleeve 32 is hinged on the lock hook 31, and the sleeve 32 is sleeved on the second threaded member 35, and an end plate 33 is fixedly connected to the second threaded member 35, and the end plate 33 is used to limit the sleeve 32 from being separated from the second threaded member 35.
[0044] The operator drives the locking hook 31 to move axially along the second threaded member 35 by screwing the second threaded member 35 , thereby driving the locking hook 31 to move axially along the second threaded member 35 , and the locking hook 31 is connected to the cable 1 , so as to adjust the tightness of the cable 1 .
[0045] In addition, a fixed pulley 34 is provided on the support plate 12 provided with the adjustment frame 3, and the cable 1 is connected to the lock hook 31 of the second threaded member 35 after passing through the fixed pulley 34. By providing the fixed pulley 34 to change the direction of the cable 1, the problem of inconvenient fixing of the cable 1 and the connecting plate due to tilting and deviation of the cable 1 when adjusting the tension is reduced.
[0046] The two cables 1 are the same cable 1, and both ends of the cable 1 are fixedly connected to the same support plate 12. The middle position of the cable 1 is fixedly connected to another support plate 12 through two fixed pulleys 34, so that two cables 1 are formed. The adjustment frame 3 is located between the two fixed pulleys 34, and the lock hook 31 can pull the cable 1 and adjust the tightness of the cable 1.
[0047] The design of the fixed pulley 34 reduces the friction between the cable 1 and the support plate 12, making the adjustment process of the cable 1 smoother, while reducing the wear on the cable 1 and extending its service life.
[0048] The implementation principle of the embodiment of the present application is: the two ends of the cable 1 are fixedly connected to the inner wall of the test space through the support plate 12, so that the cable 1 is stretched straight as the basis for installing the connecting seat 11, and then the required sensor is installed on the connecting seat 11. In this way, the cable 1 is smaller in size than the bracket, which can reduce the space occupied by the installation bracket, improve the space utilization rate, and can also reduce the impact on the test environment, which is conducive to improving the detection angle.
[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
