Description

Technical Field

[0001] The utility model relates to the technical field of sensor protection, and more specifically to a retractable rotation speed sensor housing. Background Art

[0002] The speed sensor is a sensor that converts the speed of a rotating object into an electrical output. The core component is a magnetoresistor as a detection element, which is then processed through a new signal processing circuit to reduce noise. The speed sensor is an indirect measuring device and can be manufactured using mechanical, electrical, magnetic, optical and hybrid methods. In order to protect the speed sensor in working condition, a casing is usually installed on the outside of the sensor to avoid accidents.

[0003] Based on the above, it is found that when the existing sensor housing is in use, the two symmetrically arranged upper and lower shells are mainly fixed to the outside of the sensor by bolts, but the shell is a fixed structure and cannot be telescopically adjusted. Sensors of different specifications need to be installed with corresponding shells, and the range of use is fixed. Therefore, in view of this, the existing structure is studied and improved, and a retractable speed sensor housing is provided, in order to achieve a more practical purpose. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a retractable speed sensor housing. The present invention provides a combined housing that can be telescopically adjusted. The housing can correspond to sensors of different specifications, which greatly expands the scope of use of the housing and improves the convenience of use of the housing. The housing can be stably connected to the sensor by driving the clamping assembly to slide horizontally through rotation, and the installation and subsequent disassembly of the housing are convenient.

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A retractable speed sensor housing comprises a sensor body, one end of the sensor body is fixedly connected to a sensing probe, and the other end of the sensor body is fixedly connected to a signal line, a fixing sleeve is sleeved on the outer side of the sensor body, both end faces of the fixing sleeve are provided with extension tubes, both sides of the extension tube are provided with clamping mechanisms, adjustment grooves are provided on the interior of the fixing sleeve near both ends, and a threaded ring is fixedly connected to the inner end of the extension tube.

[0007] Furthermore, the clamping mechanism includes a threaded rod, both ends of which are fixedly connected with a toggle and an anti-slip ring, a clamping block is sleeved on the outer side of the anti-slip ring, and a group of guide rods are fixedly connected to one side of the clamping block.

[0008] Furthermore, the two extension tubes are symmetrically arranged, and the extension tube and the threaded ring form an I-shaped arrangement, and the adjustment groove is T-shaped.

[0009] Furthermore, the threaded ring is located inside the adjusting groove, and the threaded ring is threadably connected to the adjusting groove.

[0010] Furthermore, the threaded rod passes through an outer end of the extension tube, and the threaded rod is threadedly connected to the extension tube.

[0011] Furthermore, the anti-slip ring is movably connected to the clamping block, the inner side of the clamping block is arranged in an arc shape, and the two clamping blocks are arranged symmetrically.

[0012] Furthermore, an outer end of the guide rod is located inside the extension tube, and the guide rod is slidably connected to the extension tube.

[0013] Compared with the prior art, the utility model has at least the following beneficial technical effects:

[0014] (1) In this solution, a fixing sleeve is provided to cooperate with an extension tube to form a protective shell. When the extension tube drives the threaded ring to rotate inside the adjustment groove, the position of the threaded ring is adjusted, and the movement of the threaded ring drives the extension tube to move outward. Compared with the prior art, a combined shell that can be telescopically adjusted is provided. The shell can correspond to sensors of different specifications, which greatly expands the use range of the shell and improves the convenience of use of the shell.

[0015] (2) By setting up a clamping mechanism, the rotation adjustment of the threaded rod cooperates with the anti-slip ring to push the clamping block to move, and the movement of the clamping block drives the guide rod to move synchronously, so that the corresponding two clamping blocks are symmetrically clamped on the outside of the sensor body, so that the position of the extension tube is fixed. Compared with the prior art, the clamping assembly is driven to slide horizontally by rotation, so that the housing can be stably connected to the sensor, and at the same time it is convenient for the installation and subsequent disassembly of the housing.
