Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a contact type displacement sensor. Background Art

[0002] A sensor is a detection device that can sense the information being measured and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. There are many types of sensors, and contact displacement sensor is one of them.

[0003] During use, if the sensor connection plug becomes loose, it will cause poor contact of the sensor, which may easily reduce the quality of sensor use. When the sensor is installed in a critical position, the action that should be achieved cannot be achieved, which may easily lead to safety accidents and casualties.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a contact displacement sensor is provided to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a contact displacement sensor to solve the problem that when the connecting plug of the sensor becomes loose during use, it will cause poor contact of the sensor, which may easily lead to reduced quality of sensor use. When the sensor is installed in a key position, the action that should be achieved cannot be achieved, which may easily lead to safety accidents and casualties.

[0006] A contact displacement sensor has an auxiliary component. Through the setting of the auxiliary component, auxiliary fixation of the plug can be achieved, thereby avoiding the plug from loosening during use, which in turn causes poor contact of the sensor and ultimately affects use. If the plug becomes loose and causes the sensor to fail, when performing an action, such as the device should stop, the sensor is damaged and cannot function. At this time, the device cannot stop, which will cause an equipment accident. If people are around at this time, they will be injured.

[0007] It also has a fixing component. When fixing the sensor, on the one hand, when the adjustment part of the fixing screw is damaged, a wrench can be directly inserted into the adjustment slot for adjustment, which improves the flexibility during installation and disassembly; on the other hand, when the fixing screw is stripped, the middle part of the screw is exposed under the support of the support plate, and a cutting tool can be used to cut off the middle part of the fixing screw, without damaging the fixing block and the sensor during cutting.

[0008] It also has a support block. Through the setting of the support block, the support of the support block can ensure the effective cooling of the bottom of the sensor, and the support block is a concave structure, which can further improve the cooling effect of the sensor. Under the support of the support block, it can be ensured that the bottom of the sensor is not in contact with the installation equipment. At this time, the bottom of the sensor can dissipate heat normally, thus ensuring the service life of the sensor. At this time, because the support block is a concave structure, the contact area between the support block and the sensor will be reduced, and the heat dissipation of the bottom of the sensor will be better guaranteed after the reduction.

[0009] The purpose and effect of the contact displacement sensor of the utility model are achieved by the following specific technical means:

[0010] The utility model provides a contact displacement sensor, which specifically comprises: a sensor;

[0011] The sensor is provided with a fixing assembly, a plug for powering the sensor is plugged into the sensor, and a contact button is provided on the sensor.

[0012] Preferably, the fixing assembly consists of a fixing block, a fixing screw, an adjustment slot and a support plate. There are two fixing blocks in total, which are respectively fixed on the left end face and the right end face of the sensor. Both fixing blocks are rectangular block structures, and each fixing block is plugged with two fixing screws for fixing the fixing block.

[0013] Preferably, each of the fixing screws is provided with an adjustment slot, which is a hexagonal slot structure and serves as an auxiliary adjustment member of the fixing screw.

[0014] Preferably, a support plate is welded to the top end surface of each of the fixing blocks, the support plate is a rectangular plate structure, and the top end surface of the support plate is clamped with the step of the fixing screw.

[0015] Preferably, an auxiliary component is installed on the sensor, and the auxiliary component consists of a mounting block, a spring rod and a contact block. There are two mounting blocks, both of which are fixed on the front end surface of the sensor, a spring rod is installed on the inner side of the two mounting blocks, and a contact block is fixed to one end of the inner side of the two spring rods.

[0016] Preferably, the two contact blocks are both made of rubber material, and the two contact blocks are in elastic contact with the left side and the right side of the plug respectively.

[0017] Preferably, two support blocks are fixed to the bottom end surface of the sensor. When the two support blocks are in contact with the mounting device, the spacing between the bottom end surface of the sensor and the mounting device is 1 cm. Both support blocks are concave structures. When connecting the plug, the two fixing screws are directly passed through the fixing blocks, and then threadedly connected to the mounting device; when connecting the plug, first move the two contact blocks to the left and right respectively, and then connect the plug to the sensor, and then loosen the two contact blocks; when disassembling maintenance or repair, the fixing screw can be directly removed with a wrench. When the adjustment part of the fixing screw is damaged, the wrench can be directly inserted into the adjustment slot for adjustment. When the fixing screw is stripped, a cutting tool can be used to cut off the middle part of the fixing screw.

[0018] Beneficial Effects

[0019] It can realize auxiliary fixation of the plug, avoid the plug loosening during use, which may cause poor contact of the sensor and ultimately affect the use. If the plug is loose and causes the sensor to fail, when performing an action, such as the equipment should stop, the sensor is damaged and cannot function. At this time, the equipment cannot be stopped, which will cause equipment accidents. If there are people around, they will be injured.

[0020] When fixing the sensor, on the one hand, when the adjustment part of the fixing screw is damaged, you can directly insert a wrench into the adjustment slot to adjust it, which improves the flexibility of installation and disassembly;

[0021] On the other hand, when the fixed screw is stripped, the middle part of the screw is exposed under the support of the support plate. At this time, a cutting tool can be used to cut off the middle part of the fixed screw without damaging the fixed block and the sensor.

[0022] The support of the support block can ensure effective cooling of the bottom of the sensor, and the support block is a concave structure, which can further improve the cooling effect of the sensor. Under the support of the support block, it can be ensured that the bottom of the sensor does not contact the installation equipment. At this time, the bottom of the sensor can dissipate heat normally, which ensures the service life of the sensor. At this time, because the support block is a concave structure, the contact area between the support block and the sensor will be reduced, and the heat dissipation of the bottom of the sensor will be better guaranteed after the reduction.
