Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
The embodiment of the utility model provides a novel tension detector, as shown in FIG. 1, include:
a housing 11 having an opening 111 at one end;
the sensor wire clamping rod 12 is sleeved in the opening 111 and used for clamping a transverse metal steel wire 13 of the tension fence;
the sensor suspension needle 14 is arranged at the bottom end of the sensor wire clamping rod 12;
the sensor suspension needle cap 15 is sleeved on the sensor suspension needle 14 and is connected with the bottom end of the sensor wire clamping rod 12 through an elastic material; a gap is reserved between the sensor suspension needle 14 and the sensor suspension needle cap 15;
a first sensor lead 16 connected to the sensor suspension pin 14;
and a second sensor lead 17 connected to the sensor needle hanging cap 15.
The working principle and the beneficial effects of the novel tension detector are as follows:
the transverse metal steel wire is connected with the sensor wire clamping rod through the bolt and the clamping piece mechanism, and the transverse metal steel wire and the sensor wire clamping rod cannot generate relative displacement when stressed, so that the connection is more stable and reliable, and the application range is wide.
The lower end of the sensor wire clamping rod is provided with a metal material suspension needle, a sensor suspension needle cap made of metal material is placed in a damping material, and the sensor suspension needle cap and the sensor wire clamping rod are connected through an elastic material and can obliquely move along with the sensor wire clamping rod. And in a normal state, the first sensor lead and the second sensor lead are open-circuited.
When an intruder pulls or cuts off the transverse metal wire, the transverse metal wire is subjected to large force, transverse acting force is conducted to the sensor wire clamping rod, the sensor wire clamping rod is stressed in the vertical direction, the sensor wire clamping rod is obliquely arranged at the bottom end and is close to the sensor wire suspension cap, the sensor wire suspension cap is connected with the sensor wire clamping rod through the elastic material, the moving amplitude is smaller than the sensor wire suspension cap, finally, the sensor wire suspension cap is in contact with the sensor wire suspension cap, and a first sensor lead and a second sensor lead are in a conduction alarm state.
When no invader exists, because environmental factors cause that the transverse metal steel wire receives the small force of the slow change of the external environment, when the transverse metal steel wire transversely generates slow movement, the sensor wire clamping rod is driven to slowly incline, because the movement is slow, the force of the damping material to the sensor suspension needle cap cannot reach the position where the sensor suspension needle cap reaches to contact with the sensor suspension needle, and the first sensor lead and the second sensor lead cannot be conducted for alarming.
The structure can be reused when the sensor suspension needle and the sensor suspension needle cap are separated under the action of the elastic material, so that the sensor can be used for multiple times, and the resetting of workers is not needed after the triggering; the sensor hangs the mechanism setting of needle and sensor hanging needle cap and has realized that the slight trigger on the horizontal metal steel wire can not produce the wrong report.
In one embodiment, as shown in fig. 1, the damping material 19 is located below the sensor wire clamping bar at the inner bottom end of the opening 111 of the housing, and the damping material 19 overflows the bottom end of the sensor pin cap 15 and does not overflow the top end of the sensor pin cap 15.
The sensor suspension needle cap made of metal materials is placed in a damping material (only granular non-conducting materials are needed), and the internal self-flowing damping design can also be self-adaptive to small tension change caused by the influence of external environmental factors, so that the false alarm rate of the system is further reduced. In addition, resistance can be generated on the sensor suspending needle cap through the damping material, so that the sensor suspending needle cap and the sensor suspending needle can be more quickly approached, and the damping material is replaced to form tension detectors with different sensitivities.
In one embodiment, the connecting the first sensor lead to the sensor suspension pin comprises:
as shown in fig. 1, a suspension wire loop 18 is formed in the sensor suspension needle 14, and the first sensor lead 15 is fixedly connected to the suspension wire loop 18.
In order to ensure the contact between the first sensor lead and the sensor suspension needle to be stable, the suspension needle wire ring and the sensor suspension needle can slide relatively and keep good electrical contact.
In one embodiment, the sensor wire clamping rod is sealed with the opening 111 of the housing by using a sealant. The sensor is guaranteed to be free of moisture inside through sealing, and the occurrence of internal circuit short circuit is avoided.
In one embodiment, the sealant is provided in an arc shape on a side close to the sensor clamping bar.
The arc-shaped arrangement is adopted, so that the sealing does not influence the movement of the lower end of the wire clamping rod of the sensor.
In one embodiment, as shown in fig. 2, the housing 11 includes two fixing legs 31 respectively provided at left and right edges of a lower surface of the housing 11; the fixing feet 31 are L-shaped in cross section for fixing the housing 11 to the detector column 5;

the fixing device 32 includes:
a fixing pad 32-1 for abutting against the detector column 5 to fix the housing 11 to the detector column 5;
one end of the spring 32-2 is fixedly connected with the fixed pad 32-1, and the other end is connected with the fixed foot 31.
In order to realize the application of the novel tension sensor in the tension fence, the tension sensor needs to be fixed on the detector column 5, the contact type tension sensor can be installed on the detector column 5 more quickly through the design of the shell, the time is saved, and the installation efficiency is improved.
In one embodiment, as shown in FIG. 3, the mounting pad 32-1 includes:
the lower end of the side surface of the fixed base 42 is provided with an external thread, and the bottom end of the fixed base 42 is connected with the spring 32-2;
a rubber pad 41 disposed on the fixed base 42 and connected to the fixed base 42;
the fixing foot 31 is provided with a groove hole 43 at the connecting position of the fixing foot 31 and the spring 32-2, the size of the groove hole 43 is matched with that of the spring 32-2, a cavity 44 is arranged below the groove hole 43, the cavity 44 is communicated with the groove hole 43, a fixing plate 45 is arranged in the cavity 44, the fixing plate 45 is fixedly connected with the spring 32-2, the size of the fixing plate 45 is larger than that of the groove hole 43, and the upper end of the groove hole 43 is provided with an internal thread matched with the external thread.
When it is not necessary to secure the housing to the detector column, the mounting pads may be secured by rotation into the recessed holes of the mounting feet.
