Description

Technical Field

[0001] This invention relates to the field of quartz temperature sensor technology, specifically a quartz tuning fork temperature sensor. Background Technology

[0002] A temperature sensor is a device or system that can convert temperature, a non-electrical quantity, into an electrical quantity, thereby enabling temperature measurement, transmission, processing, or automatic control. Temperature sensors are widely used in many fields, including but not limited to industrial, agricultural, commercial, and household equipment.

[0003] However, existing temperature sensors cannot be shockproof during use. This leads to the internal parts gradually loosening over time, and in severe cases, damage, rendering them unusable. Furthermore, the sensor is typically encased within two semicircles joined by a snap-fit ​​mechanism, which can damage the snap-fit ​​mechanism under prolonged vibration, exposing the internal sensor and affecting its normal operation. Therefore, we have made improvements to address this issue by proposing a quartz tuning fork temperature sensor. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a quartz tuning fork temperature sensor. This solves the problem that existing temperature sensors cannot be shockproof during use, which leads to internal parts gradually loosening and potentially becoming damaged over time, rendering them unusable. Furthermore, the sensor is typically encased within two semicircles joined by a snap-fit ​​mechanism, which can damage the snap-fit ​​mechanism under prolonged vibration, exposing the internal sensor and affecting its normal operation.

[0009] Preferably, the T-shaped serrated movable strip is movably clamped to the inclined clamping plate, the inclined clamping plate is disposed inside the first fixed base, the first fixed base is fixedly installed inside the receiving cavity opened on one side of the movable outer shell, and the limit outer shell is fixedly installed on the outer surface of the first fixed base.

[0010] Preferably, the energy-absorbing and shock-absorbing mechanism includes a first reset spring and a rectangular connecting plate;

[0011] The rectangular connecting plates are fixedly installed on the inner surfaces of the protective shell and the movable shell by bolts, and a first return spring is fixedly installed on one side of each rectangular connecting plate.

[0012] Preferably, the other end of the first reset spring is fixedly installed on one side surface of the rectangular limiting plate. Several rectangular fixing rods are fixedly installed circumferentially on the side of the rectangular limiting plate away from the first reset spring. An elliptical connecting rod is movably installed at the end of each rectangular fixing rod away from the rectangular limiting plate through a rotating shaft. A U-shaped fixing block is movably installed at the end of each elliptical connecting rod away from the rectangular fixing rod through a rotating shaft.

[0013] Preferably, the center of the U-shaped fixing block is fixedly installed on one side surface of the connecting fixing plate, and a circular connecting block is fixedly installed on one side of the center of the connecting fixing plate. The end of the circular connecting block away from the connecting fixing plate is fixedly installed on the outer surface of the sensor body.

[0014] Preferably, a connecting column is fixedly installed at the center of the side of the connecting fixing plate away from the circular connecting block. An energy-absorbing spring is sleeved on the outer surface of the connecting column. A circular transmission plate is fixedly installed at the end of the connecting column away from the connecting fixing plate. The circular transmission plate is movably installed inside the fixed housing. The fixed housing is fixedly installed at the center of the rectangular limiting plate. A rubber ring fixing seat is provided at the bottom of the rectangular limiting plate. An energy-absorbing rubber ring is installed inside the rubber ring fixing seat.

[0015] Preferably, each of the elliptical connecting rods has a T-shaped groove inside, and a T-shaped connecting block is movably installed inside each T-shaped groove. A first circular connecting block is fixedly installed at the end of each T-shaped connecting block away from the T-shaped groove, and one end of a telescopic rod is fixedly installed on one side of each first circular connecting block.

[0016] Preferably, a second circular connecting block is fixedly installed at the end of each telescopic rod away from the first circular connecting block, and a fixed connecting post is fixedly installed at the end of each second circular connecting block away from the telescopic rod. The fixed connecting post is fixedly installed on one side surface of the circular connecting block, and a buffer spring is sleeved on the outer surface of each telescopic rod.

[0017] This invention provides a quartz tuning fork temperature sensor. It has the following advantages:

[0018] Firstly, by installing the sensor body inside the protective housing and the movable housing, when shaking occurs during use, the vibration generated by the shaking will be transmitted to the energy-absorbing and shock-absorbing mechanism. The energy-absorbing and shock-absorbing mechanism can dissipate the vibration force and absorb the kinetic energy generated by the shaking, making the internal parts more stable and preventing damage to the internal parts. At the same time, the protective housing and the movable housing are connected by a sealing and locking mechanism. When locked, it can prevent the vibration generated by shaking from causing the protective housing and the movable housing to open and expose the sensor body, thus preventing damage to the sensor body.

[0019] The vibration generated by the sensor body during use is transmitted to the first reset spring and the rectangular connecting plate in the energy absorption and shock absorption mechanism. The first reset spring can absorb part of the vibration, and then the remaining vibration will be transmitted to the elliptical connecting rod and the rectangular fixing rod. The buffer spring and telescopic rod installed between the rectangular fixing rod and the rectangular limiting plate can absorb the remaining vibration, thereby preventing the vibration from being transmitted to the sensor body and effectively preventing the loosening of the internal parts of the sensor body.

[0020] Meanwhile, the first circular connecting block fixedly installed at one end of the telescopic rod, together with the T-shaped connecting block, can provide a certain displacement when the connecting fixing plate shakes, thus avoiding breakage due to excessive pressure.

[0021] When the connecting plate is shaken, the connecting column fixed on one side will work with the circular transmission plate to transmit kinetic energy to the surface of the energy-absorbing rubber ring. At this time, the energy-absorbing rubber ring will absorb part of the kinetic energy, effectively avoiding damage to the sensor body caused by the vibration force generated by the shaking.

[0022] After the sensor body is installed, the protective shell and the movable shell are merged. During the merging, the movable T-shaped serrated strip is locked inside the locking buckle with the through hole. At this time, the T-shaped serrated strip is locked onto the inclined locking plate installed inside the first fixed base. The teeth on one side of the T-shaped serrated strip and the teeth on one side of the inclined locking plate will mesh with each other. Then, the protrusion on one end of the T-shaped serrated strip will lock onto one side of the limiting shell, thus locking it in place. This effectively prevents the protective shell and the movable shell from opening due to vibration during shaking, and effectively avoids the sensor body being exposed and damaged.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example:

[0038] like Figures 1 to 3 As shown, this embodiment of the invention provides a quartz tuning fork temperature sensor, including a protective housing 1. A movable housing 2 is movably mounted on one side of the protective housing 1 via a hinge. A sensor body 3 is installed inside the protective housing 1 and the movable housing 2. The connection between the protective housing 1 and the movable housing 2 is connected by a sealing locking mechanism 6. The sensor body 3 is connected to the protective housing 1 by an energy-absorbing and shock-absorbing mechanism 4. A plurality of fixed bases 7 are fixedly mounted on one end of the sensor body 3. A return spring 8 is fixedly mounted on the side of each fixed base 7 away from the sensor body 3. One end of each return spring 8 is fixedly mounted on the inside side of the protective housing 1.

[0039] like Figures 8 to 12 As shown, the sealing locking mechanism 6 includes a fixed connecting plate 605 and a U-shaped limiting plate 604;

[0040] The fixed connecting plate 605 is fixedly installed inside one side of the receiving cavity 5, which is located at the connection between the protective shell 1 and the movable shell 2. A U-shaped limiting plate 604 is fixedly installed at the end of the fixed connecting plate 605 away from the receiving cavity 5. A T-shaped serrated movable strip 603 is movably installed inside the center of the U-shaped limiting plate 604. A through hole 601 is opened in the center of the T-shaped serrated movable strip 603. The through hole 601 is movably locked onto the outer surface of the locking buckle 606. The locking buckle 606 is fixedly installed on one side surface of the U-shaped limiting plate 604. The T-shaped serrated movable strip 603 is movably locked onto the inclined locking plate 602. The inclined locking plate 602 is located inside the first fixed base 608. The first fixed base 608 is fixedly installed inside the receiving cavity 5 opened on one side of the movable shell 2. The outer surface of the first fixed base 608 is... The protective housing 607 is fixedly installed on the surface. After the sensor body 3 is installed, the protective housing 1 and the movable housing 2 are merged. During the merging, the movable T-shaped serrated strip 603 is locked into the through hole 601 inside the locking buckle 606 for fixation. At this time, the T-shaped serrated strip 603 is movably locked onto the inclined locking plate 602 installed inside the first fixed base 608. At this time, the toothed strip on one side of the T-shaped serrated strip 603 will mesh with the toothed strip on one side of the inclined locking plate 602. Then, the protrusion on one end of the T-shaped serrated strip 603 will lock onto one side of the limiting housing 607, thereby locking it. This can effectively prevent the protective housing 1 and the movable housing 2 from opening due to the vibration force generated during shaking, and effectively avoid the sensor body 3 being exposed and damaged.

[0041] like Figures 4 to 7 As shown, the energy-absorbing and shock-absorbing mechanism 4 includes a first reset spring 407 and a rectangular connecting plate 408;

[0042] The rectangular connecting plate 408 is fixedly installed on the inner surface of the protective shell 1 and the movable shell 2 by bolts. A first return spring 407 is fixedly installed on one side of each rectangular connecting plate 408. The other end of the first return spring 407 is fixedly installed on one side surface of the rectangular limiting plate 405. Several rectangular fixing rods 404 are circumferentially fixed on the side of the rectangular limiting plate 405 away from the first return spring 407. An elliptical connecting rod 403 is movably installed at the end of each rectangular fixing rod 404 away from the rectangular limiting plate 405 via a rotating shaft. A U-shaped fixing block 402 is movably installed at the end of each elliptical connecting rod 403 away from the rectangular fixing rod 404 via a rotating shaft. The center of 02 is fixedly installed on one side surface of the connecting fixing plate 401. A circular connecting block 406 is fixedly installed on one side of the center of the connecting fixing plate 401. The end of the circular connecting block 406 away from the connecting fixing plate 401 is fixedly installed on the outer surface of the sensor body 3. A connecting column 421 is fixedly installed at the center of the side of the connecting fixing plate 401 away from the circular connecting block 406. An energy-absorbing spring 420 is sleeved on the outer surface of the connecting column 421. A circular transmission plate 419 is fixedly installed at the end of the connecting column 421 away from the connecting fixing plate 401. The circular transmission plate 419 is movably installed inside the fixed housing 418. The fixed housing 418 is fixedly installed at the center of the rectangular limiting plate 405. A rubber ring fixing seat 417 is provided at the bottom of the inner side of the plate 405. An energy-absorbing rubber ring 416 is installed inside the rubber ring fixing seat 417. Each elliptical connecting rod 403 has a T-shaped groove 411 inside. A T-shaped connecting block 409 is movably installed inside each T-shaped groove 411. A first circular connecting block 410 is fixedly installed at the end of each T-shaped connecting block 409 away from the T-shaped groove 411. One end of a telescopic rod 413 is fixedly installed on one side of each first circular connecting block 410. A second circular connecting block 414 is fixedly installed at the end of each telescopic rod 413 away from the first circular connecting block 410. Each second circular connecting block 414 is located away from the telescopic rod. Each of the 413 telescopic rods has a fixed connecting post 415 fixedly installed at one end. The fixed connecting post 415 is fixedly installed on one side surface of the circular connecting block 406. A buffer spring 412 is sleeved on the outer surface of each telescopic rod 413. The vibration force generated by the sensor body 3 during use is transmitted to the first reset spring 407 and the rectangular connecting plate 408 in the energy absorption and shock absorption mechanism 4. The first reset spring 407 can absorb part of the vibration force. Subsequently, the remaining vibration force is transmitted to the elliptical connecting rod 403 and the rectangular fixed rod 404. The buffer spring 412 and the telescopic rod 413 installed between the rectangular fixed rod 404 and the rectangular limiting plate 405 can absorb the remaining vibration force, thereby preventing the vibration from being transmitted to the sensor body 3.This effectively prevents the internal components of the sensor body 3 from becoming loose;

[0043] Meanwhile, the first circular connecting block 410 fixedly installed at one end of the telescopic rod 413, together with the T-shaped connecting block 409, can provide a certain displacement when the connecting fixing plate 401 shakes, so as to avoid breakage due to excessive pressure.

[0044] When the connecting plate 401 is shaken, the connecting column 421 fixed on one side will work with the circular transmission plate 419 to transmit kinetic energy to the surface of the energy-absorbing rubber ring 416. At this time, the energy-absorbing rubber ring 416 absorbs part of the kinetic energy, effectively preventing damage to the sensor body 3 caused by the vibration force generated by the shaking.

[0045] Working principle:

[0046] Firstly, by installing the sensor body 3 inside the protective housing 1 and the movable housing 2, when shaking occurs during use, the vibration generated by the shaking will be transmitted to the energy-absorbing and shock-absorbing mechanism 4. The energy-absorbing and shock-absorbing mechanism 4 can dissipate the vibration force, and at the same time, the kinetic energy generated by the shaking will be absorbed, making the internal parts more stable and preventing damage to the internal parts. Meanwhile, the protective housing 1 and the movable housing 2 are connected by a sealing and locking mechanism 6. While locking, it can prevent the vibration generated by shaking from causing the protective housing 1 and the movable housing 2 to open, exposing the sensor body 3 to the outside, thus preventing damage to the sensor body.

[0047] The vibration force generated by the sensor body 3 during use will be transmitted to the first reset spring 407 and the rectangular connecting plate 408 in the energy absorption and shock absorption mechanism 4. The first reset spring 407 can absorb part of the vibration force, and then the other vibration force will be transmitted to the elliptical connecting rod 403 and the rectangular fixing rod 404. The buffer spring 412 and the telescopic rod 413 installed between the rectangular fixing rod 404 and the rectangular limiting plate 405 can absorb the other vibration force, thereby preventing the vibration from being transmitted to the sensor body 3 and effectively preventing the loosening of the internal parts of the sensor body 3.

[0048] Meanwhile, the first circular connecting block 410 fixedly installed at one end of the telescopic rod 413, together with the T-shaped connecting block 409, can provide a certain displacement when the connecting fixing plate 401 shakes, so as to avoid breakage due to excessive pressure.

[0049] When the connecting plate 401 is shaken, the connecting column 421 fixed on one side will cooperate with the circular transmission plate 419 to transmit kinetic energy to the surface of the energy-absorbing rubber ring 416. At this time, the energy-absorbing rubber ring 416 absorbs part of the kinetic energy, effectively avoiding damage to the sensor body 3 caused by the vibration force generated by the shaking.

[0050] After the sensor body 3 is installed, the protective shell 1 and the movable shell 2 are merged. During the merging, the movable T-shaped serrated strip 603 is locked inside the through hole 601 of the T-shaped serrated strip 603 and fixed inside the locking buckle 606. At this time, the T-shaped serrated strip 603 is movably locked onto the inclined locking plate 602 installed inside the first fixed base 608. At this time, the toothed strip on one side of the T-shaped serrated strip 603 and the toothed strip on one side of the inclined locking plate 602 will mesh with each other. Then, the protrusion on one end of the T-shaped serrated strip 603 will lock onto one side of the limiting shell 607, thereby locking it. This can effectively prevent the protective shell 1 and the movable shell 2 from opening due to the vibration force generated during shaking, and effectively avoid the sensor body 3 being exposed and damaged.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
