Description

Technical Field

[0001] The utility model belongs to the technical field of storage equipment, and particularly relates to a storage and fixing device for a thermocouple temperature measuring line. Background Art

[0002] Thermocouples are commonly used temperature measuring elements in temperature measuring instruments. They measure temperature directly and convert temperature signals into thermoelectric potential signals through the thermocouple temperature measuring wire connected to them, and then convert them into the temperature of the measured medium through electrical instruments. They are usually used in conjunction with display instruments, recording instruments and electronic regulators. For example, the commonly used YOKOGAWA GX / GP series instruments can measure the sensor input, DC voltage, switch quantity, DC current (mA), pulse, and resistance input of thermocouples and thermal resistors, and after sampling the input signal in the input module according to the set measurement cycle, perform A / D conversion, collect data according to the measurement cycle, and display and record them.

[0003] At present, the commonly used length of thermocouple temperature measuring wire is 3~5m or even longer. During the measurement experiment, the two ends of the thermocouple temperature measuring wire need to be connected to the measuring instrument and the thermocouple respectively, and the thermocouple is attached to the sample to be measured. Since the thermocouple temperature measuring wire is a hard wire, it is not easy to bend. If it is bent forcibly or the degree of bending is too large, it will affect the service life of the thermocouple temperature measuring wire and even cause the internal wire core to break and be damaged. Therefore, it occupies a large space, making the environment messy and not conducive to sorting; at the same time, such measurement experiments generally involve multiple groups of experiments to measure at the same time. For example, the GX / GP series instruments are equipped with 20~500 input / output channels. At this time, the number of thermocouple temperature measuring wires is the same as the number of measurement channels. A large number of thermocouple temperature measuring wires are placed randomly, overlapped and cross-entangled with each other, making it difficult to identify and distinguish the experimental groups corresponding to the thermocouple temperature measuring wires, causing inconvenience in the measurement experiment; in addition, after the measurement experiment is completed, it is difficult to sort and collect the thermocouple temperature measuring wires, and they are very easy to get tangled, which greatly increases the difficulty of collection and sorting and the risk of damage to the thermocouple temperature measuring wires.

[0004] Therefore, it is necessary to design a thermocouple temperature measuring wire storage and fixing device that can effectively organize the thermocouple temperature measuring wires and facilitate use and collection. Summary of the invention

[0005] In order to solve the above technical problems, the utility model proposes a storage and fixing device for thermocouple temperature measuring wires, which is flexible and convenient to use, makes the thermocouple temperature measuring wires regular and uniform, facilitates the identification of wiring of different experimental groups, effectively reduces the occupied space of the thermocouple temperature measuring wires, avoids entanglement between different temperature measuring wires, and facilitates storage and arrangement, thereby avoiding damage to the thermocouple temperature measuring wires, extending the service life of the temperature measuring wires, and improving the efficiency of experimental measurement.

[0006] The technical solution of the utility model is:

[0012] Preferably, a pressure plate is movably embedded inside the front card plate and the rear card plate;

[0013] A plurality of compression springs are arranged between the upper end surface of the pressure plate and the front clamping plate and the rear clamping plate, so that the lower end surface of the pressure plate abuts against the compression locking groove and plays a role in clamping and limiting the thermocouple temperature measuring line.

[0014] Preferably, the partition plate is provided with a hanging groove, and the hanging groove is arranged near the edge of the partition plate and is used for temporarily hanging the thermocouple temperature measuring line.

[0015] Preferably, the hanging groove comprises a connected slotted portion and a clamp portion, the slotted portion and the clamp portion are bent and connected, and the thermocouple temperature measuring wire can slide into the slotted portion and be clamped on the clamp portion.

[0016] Preferably, the connecting shaft is rotatably mounted between the left bracket and the right bracket, and at least one end of the connecting shaft is provided with a turning handle fixedly connected thereto.

[0017] Preferably, the left bracket, the right bracket and the partition plate are all provided with a plurality of heat dissipation holes distributed at intervals.

[0018] Preferably, the outer side surfaces of the front card plate and the rear card plate are provided with a plurality of identification parts distributed at intervals;

[0023] Compared with the prior art, the utility model has the following advantages and effects:

The pressure plate cooperates with the compression lock groove to achieve the compression and fixation of the thermocouple temperature measuring wire. Under normal conditions, the pressure plate and the compression groove are in abutment. When the thermocouple temperature measuring wire needs to be placed, it is only necessary to lift the pressure plate upward with force and place the thermocouple temperature measuring wire in the compression lock groove. The pressure plate will automatically reset and compress the thermocouple temperature measuring wire, thereby preventing the thermocouple temperature measuring wire from moving or detaching, and ensuring the stability of the connection during the measurement experiment.

[0034] In order to enable those skilled in the art to better understand the present invention, the present invention is now further described in conjunction with specific implementation methods.

[0035] Embodiment 1:

The front card plate 3 and the rear card plate 4 are both arranged between the left bracket 1 and the right bracket 2 and are vertically connected thereto.

[0037] Optionally, in some embodiments, the left bracket 1, the right bracket 2, the front clamping plate 3, and the rear clamping plate 4 are an integrally formed structure, which can effectively improve the toughness and stability of the overall device.

[0038] like Figure 1 , Figure 2 As shown, a fixing seat 12 is provided at the bottom end of the left bracket 1 and the right bracket 2 for fixing the left bracket 1 and the right bracket 2. Specifically, the fixing seat 12 is provided with a bolt hole or a hook hole, so that the entire device can be fixed or hung to a specified position through the fixing seat 12 to avoid confusion and reduce disconnection or falling caused by accidental touch, so as to achieve stable placement of the entire device.

[0039] like Figure 3As shown, a connecting shaft 5 vertically connected thereto is provided between the left bracket 1 and the right bracket 2. The connecting shaft 5 is rotatably mounted between the left bracket 1 and the right bracket 2. A turning handle 51 fixedly connected thereto is provided at the left end of the connecting shaft 5. The turning handle 51 can be turned to achieve synchronous storage and sorting of multiple groups of thermocouple temperature measuring wires, thereby improving sorting efficiency. The connecting shaft 5 is provided with a plurality of partition plates 6 evenly spaced along its axial direction. Adjacent partition plates 6 form a storage space for accommodating thermocouple temperature measuring wires.

[0040] like Figure 1 and Figure 2 As shown, the partition plate 6 is provided with a hanging groove 61, which is arranged near the edge of the partition plate 6, and includes a connected slot portion 611 and a clamp portion 612, the slot portion 611 and the clamp portion 612 are bent and connected, the thermocouple temperature measuring wire can slide into the slot portion 611 and be clamped in the clamp portion 612, and there is no need to manually fix the end of the thermocouple temperature measuring wire, so as to facilitate the winding of a longer thermocouple temperature measuring wire.

[0041] like Figure 2 , Figure 3 As shown, the front card plate 3 and the rear card plate 4 are provided with a plurality of evenly spaced compression lock grooves 7, which respectively penetrate the front card plate 3 and the rear card plate 4 from front to back, and the compression lock grooves 7 correspond to the plurality of accommodation spaces formed by the partition plate 6 one by one; Figure 3 As shown, the compression locking groove 7 includes a snap-in portion 71, a transition portion 72, and a receiving portion 73 which are connected in sequence.

For specific reference Figure 6As shown, the lower end surface of the pressure plate 8 abuts against the lower end surface of the transition portion 72 to close the transition portion 72 and the receiving portion 73 of the compression locking groove 7. The pressure plate 8 is lifted so that its lower end surface is not lower than the upper end surface of the transition portion 72, so that the thermocouple temperature measuring line can be inserted into the receiving portion 73 through the transition portion 72 or taken out through the snap-in portion 71. At this time, the clamping spring 9 is in a compressed state. After the lifting force on the pressure plate 8 is released, the pressure plate 8 will automatically reset downward to the state of closing the transition portion 72 under the action of the clamping spring 9.

[0043] Optionally, in some embodiments, the pressure plate 8 is an independent plate body adapted to the pressure locking groove 7, that is, the pressure plate 8 is not a long whole plate as in the above embodiments, but a plurality of independently separated plate bodies adapted to the pressure locking groove 7, and each independent pressure plate 8 is provided with an independent clamping spring 9, so as to realize independent clamping control of different pressure locking grooves 7. At this time, the number of pressure plates 8, clamping springs 9 and pressure locking grooves 7 is the same, which effectively increases the flexibility of use of the overall device.

Especially when multiple groups of experimental groups are involved, the identification can be flexibly and conveniently performed, so as to facilitate the experimenters to connect and disconnect different groups of thermocouple temperature measuring lines, and to record and distinguish the data of the corresponding groups.
