Description

Technical Field

[0001] This utility model relates to the field of thermometer technology, specifically to an industrial thermometer with a guiding detection mechanism. Background Technology

[0002] Temperature monitoring is a crucial step in ensuring the safe operation of equipment and the stability of processes during industrial production.

[0003] A search revealed a utility model patent with patent authorization announcement number CN110672219B, which discloses a high-precision industrial digital display thermometer, belonging to the field of thermometer equipment technology. The key technical features include a thermometer body, a data cable on the thermometer body, a temperature probe connected to the data cable, a probe handle on the temperature probe, and a handle extension assembly on the probe handle. The handle extension assembly includes an extension sleeve and a snap-fit ​​assembly. The extension sleeve is fitted onto the probe handle and slidably connected to the probe handle. The snap-fit ​​assembly is located between the probe handle and the extension sleeve to fix the extension sleeve.

[0004] Traditional industrial thermometers are usually installed in a fixed position or handheld. However, in confined spaces, high temperature and high pressure environments, or scenarios requiring multi-angle detection, the detection head is difficult to directly contact hidden areas, which has limitations. Utility Model Content

[0005] The purpose of this invention is to provide an industrial thermometer with a guiding detection mechanism, which solves the problem of limited detection area in traditional industrial thermometers, especially handheld industrial thermometers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an industrial thermometer with a guiding detection mechanism, comprising a thermometer, a wire harness extending from the bottom of the thermometer, a detection head at the end of the wire harness, a hollow sleeve slidably connected to the outside of the wire harness, a ball head shaft movably connected inside the hollow sleeve, the wire harness passing through the ball head shaft and slidably connected to the ball head shaft, a wire clamping mechanism provided on the ball head shaft, a connecting plate fixedly connected to the ball head shaft, and an operating rod fixedly connected to the connecting plate.

[0007] Preferably, a fixing ring is fixedly connected to the wire harness, and a spring is fixedly connected between the fixing ring and the hollow sleeve, with the spring sleeve located outside the wire harness. The fixing ring and spring sleeve provide auxiliary repositioning for any bending or twisting of the wire harness as it rotates along the ball joint shaft.

[0008] Preferably, the hollow sleeve has an internal cavity, the diameter of which is larger than the diameter of the wire harness. This cavity serves to accommodate the portion of the wire harness that bends as it rotates along the ball joint shaft.

[0009] Preferably, a round button is fixedly connected to the end of the operating lever, and the round button and the operating lever are an integral structure. The round button improves the convenience for operators to operate the operating lever.

[0010] Preferably, the wire clamping mechanism includes an inner conical sleeve threaded to the outside of the ball head shaft. Two sliding pins are slidably connected to the side wall of the ball head shaft, and these pins penetrate the side wall of the ball head shaft. One end of each sliding pin abuts against the inner conical surface of the inner conical sleeve, and the other end of each sliding pin is fixedly connected to a clamping block, which abuts against the wire harness. This wire clamping mechanism clamps and fixes the portion of the wire harness inside the ball head shaft, allowing this portion of the wire harness to adjust its angle along with the ball head shaft, thereby adjusting the orientation of the detection head at the end of the wire harness.

[0011] Preferably, a second spring is sleeved on the outer side of the sliding pin. One end of the second spring is fixedly connected to the clamping block, and the other end of the second spring is fixedly connected to the inner wall of the ball joint shaft. The second spring provides auxiliary reset for the clamping block but does not participate in the clamping force.

[0012] Preferably, a guide sleeve is fixedly connected to the clamping block, and a guide rod is slidably connected inside the guide sleeve. The end of the guide rod is fixedly connected to the inner wall of the ball joint shaft. The guide sleeve and guide rod provide guidance for the extension and retraction of the sliding pin and the clamping block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a sliding connection structure between a ball head shaft and a hollow sleeve, and then, with the help of an operating rod, the orientation of the detection head can be flexibly adjusted to meet the industrial detection needs of different angles. In addition, a wire clamping mechanism is set at the ball head shaft. The wire clamping mechanism uses the inner conical sleeve to push the sliding pin and the clamping block to fix the wire harness, ensuring that the detection head remains stable when adjusting the angle.

[0015] 2. This utility model, through the cooperation of the fixing ring and the spring, enables the wire harness to automatically return to its original position after bending, reducing wire fatigue caused by long-term use. At the same time, a cavity is set inside the hollow sleeve, which provides sufficient bending space for the wire harness when bending, avoiding damage from excessive bending.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 An industrial thermometer with a guiding detection mechanism includes a thermometer 1, a wire harness 2 extending from the bottom of the thermometer 1, a detection head 3 at the end of the wire harness 2, a hollow sleeve 4 slidably connected to the outside of the wire harness 2, a ball head shaft 5 movably connected inside the hollow sleeve 4, the wire harness 2 passing through the ball head shaft 5 and slidably connected to the ball head shaft 5, a fixing ring 7 fixedly connected to the wire harness 2, and a spring 8 fixedly connected between the fixing ring 7 and the hollow sleeve 4, with the spring 8 sleeved on the outside of the wire harness 2. The fixing ring 7 and the spring 8 provide auxiliary reset for any bending or rotational bending of the wire harness 2 following the ball head shaft 5. A connecting plate 9 is fixedly connected to the ball head shaft 5, and an operating lever 10 is fixedly connected to the connecting plate 9. A round button 11 is fixedly connected to the end of the operating lever 10, and the round button 11 and the operating lever 10 are an integral structure. The round button 11 improves the ease of operation for the operator.

[0023] Please see Figures 3-4A wire clamping mechanism 6 is provided on the ball head shaft 5. This mechanism clamps and fixes the portion of the wire harness 2 inside the ball head shaft 5, allowing this portion of the wire harness 2 to adjust its angle along with the ball head shaft 5, thereby adjusting the orientation of the detection head 3 at the end of the wire harness 2. The wire clamping mechanism 6 includes an inner conical sleeve 61 threaded to the outside of the ball head shaft 5. Two sliding pins 62 are slidably connected to the side wall of the ball head shaft 5, and each pin 62 penetrates the side wall. One end of each pin 62 abuts against the inner conical surface of the inner conical sleeve 61, and the other end of each pin 62 is fixedly connected to a clamping block 63, which abuts against the wire harness 2. A second spring 64 is sleeved on the outside of each pin 62. One end of the second spring 64 is fixedly connected to the clamping block 63, and the other end is fixedly connected to the inner wall of the ball head shaft 5. The second spring 64 assists in the reset of the clamping block 63 but does not participate in the clamping force. A guide sleeve 65 is fixedly connected to the clamping block 63, and a guide rod 66 is slidably connected inside the guide sleeve 65. The end of the guide rod 66 is fixedly connected to the inner wall of the ball head shaft 5. The guide sleeve 65 and the guide rod 66 provide guidance for the extension and retraction of the sliding pin 62 and the clamping block 63.

[0024] The specific implementation process of this utility model is as follows: In use, firstly, the inner conical sleeve 61 is screwed on, and the inner conical sleeve 61 moves axially along the ball head shaft 5. During its movement, it can apply a radial thrust to the sliding pin 62, so that the clamping block 63 at the end of the sliding pin 62 clamps the wire harness 2. In this way, the part of the wire harness 2 near the detection head 3 can rotate together with the ball head shaft 5. Then, the operator can hold the round button 11 to push or pull or drive the ball head shaft 5 to move inside the hollow sleeve 4, so that the orientation of the detection head 3 can be flexibly adjusted to meet the industrial detection needs of different angles. Moreover, the part of the wire harness 2 bent inside the hollow sleeve 4 can be inside the cavity 41 and will not be squeezed. Furthermore, through the cooperation of the fixing ring 7 and the spring 8, the wire harness 2 can automatically return to its original position after bending, reducing wire fatigue caused by long-term use.
