Technical Field

[0001] This utility model relates to the field of temperature sensor technology, specifically to a flexible snap-fit ​​temperature sensor. Background Technology

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. Temperature sensors are the core component of temperature measuring instruments and come in many varieties. They can be broadly classified into two categories based on the measurement method: contact and non-contact. Based on the sensor materials and electronic component characteristics, they are further divided into resistance temperature detectors (RTDs) and thermocouples. A temperature sensor mainly consists of a main body, connecting wires, and a sensing head. In use, the operator holds the main body and inserts the sensing head into the object to be measured. The information sensed by the sensing head is transmitted through the main body and connecting wires.

[0003] The above-mentioned technical conditions also have the drawback that when using the temperature sensor, it is not convenient to manually hold the main body of the temperature sensor and insert the sensing head into the object to be measured.

[0004] Based on this, this utility model designs a flexible snap-fit ​​temperature sensor to solve the above problems. Utility Model Content

The sensing head is disposed on the body, the connecting wire is disposed on the body, and an elastic sleeve is fitted onto the body. Two snap-fit ​​grooves are provided on the elastic sleeve. A fixing ring is fixedly connected to the elastic sleeve, and the fixing ring is fitted onto the body. A positioning groove is provided on the fixing ring. Each snap-fit ​​groove includes an access section, a connecting section, and a snap-fit ​​section. The connecting section is located between the access section and the snap-fit ​​section, and the positioning groove communicates with the access section.

[0007] Preferably, a reinforcing ring is fixedly provided on the elastic sleeve, and the reinforcing ring is fixedly connected to the end of the elastic sleeve away from the sensing head.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0018] A flexible snap-fit ​​temperature sensor includes a body 4, a connecting wire 5, and a sensing head 1. The sensing head 1 is mounted on the body 4, and the connecting wire 5 is mounted on the body 4. An elastic sleeve 3 is fitted onto the body 4, and two snap-fit ​​grooves 8 are provided on the elastic sleeve 3.

[0019] A retaining ring 9 is fixedly connected to one end of the elastic sleeve 3 near the sensing head 1, and the retaining ring 9 is sleeved on the main body 4. A positioning groove 2 is provided on the retaining ring 9, and the snap-fit ​​groove 8 includes an access section 12, a connecting section 11 and a snap-fit ​​section 10. The connecting section 11 is located between the access section 12 and the snap-fit ​​section 10, and the positioning groove 2 communicates with the access section 12.

[0020] The hook 16 is inserted into the positioning groove 2, and then enters the snap-fit ​​groove 8 through the positioning groove 2. The hook 16 is then snapped into the snap-fit ​​section 10 of the snap-fit ​​groove 8, and is stably hung on the elastic sleeve 3 under the action of the snap-fit ​​groove 8. The hook 16 is fixed to the item to be tested, and the sensor head 1 is inserted into the item. With the action of the hook 16, the main body 4 can be stably held on the item without manual intervention, making the temperature sensor's detection of the item more convenient.

[0021] A reinforcing ring 7 is fixedly installed on the elastic sleeve 3. The reinforcing ring 7 is fixedly connected to the end of the elastic sleeve 3 away from the sensor head 1. The reinforcing ring 7 serves to strengthen the elastic sleeve 3, so that the elastic sleeve 3 can be better fitted onto the main body 4. The connecting section 11 is inclinedly installed on the elastic sleeve 3. When the hook 16 enters the snap-fit ​​groove 8, the hook 16 is not easy to slip out of the snap-fit ​​groove 8 under the action of the connecting section 11.

[0022] A limiting groove 14 is formed on the main body 4, and a limiting ring 15 is fixedly installed on the inner side wall of the elastic sleeve 3. The limiting ring 15 is engaged in the limiting groove 14, and the limiting ring 15 and the limiting groove 14 prevent the elastic sleeve 3 from slipping off the main body 4. A spring 13 is sleeved in the limiting groove 14, between the limiting groove 14 and the limiting ring 15. One end of the spring 13 is pressed against the grass, and the other end of the elastic sleeve is pressed against the limiting ring 15.

[0023] Under the action of spring 13, the retaining ring 9 is always fitted onto the main body 4, making it difficult for the hook 16 to enter the locking groove 8 from the positioning groove 2 at the retaining ring 9. When the hook 16 needs to be used, hold the main body 4 with one hand and the elastic sleeve 3 with the other hand, then compress the spring 13. The retaining ring 9 extends out of the main body 4, making it easier for the hook 16 to enter the locking groove 8 through the positioning groove 2. An auxiliary plane 6 is provided at the end of the main body 4 away from the sensor head 1. There are two mirror images of the auxiliary plane 6 on the main body 4. The two auxiliary planes 6 can increase the contact area between the hand and the main body 4, making it easier to apply force with the hand.

[0024] The implementation principle of this embodiment is as follows: When in use, hold the main body 4 with one hand and the elastic sleeve 3 with the other hand, then compress the spring 13, the fixing ring 9 extends out of the main body 4, and the hook 16 extends from the positioning groove 2 of the fixing ring 9 into the snap-fit ​​groove 8. After passing through the access section 12 and the connecting section 11 of the snap-fit ​​groove 8, the hook 16 is snapped into the snap-fit ​​section 10. Then release the elastic sleeve 3, the spring 13 returns to its original position, the fixing ring 9 is re-sleeved on the main body 4, and the hook 16 is stabilized on the elastic sleeve 3. At this time, the sensing head 1 is inserted into the item to be tested, and the hook 16 is fixed on the item to be tested. Under the action of the hook 16, the main body 4 can be stabilized on the item to be tested without manual holding, thus making it more convenient for the temperature sensor to detect the item.
