Description

Technical Field

[0001] This utility model relates to the field of encoder housing technology, specifically to an integrated housing for a compact incremental encoder. Background Technology

[0002] The core function of an encoder is to convert information from one form to another. An incremental encoder is a device used to measure rotational or linear motion. It achieves high-precision motion monitoring and control by converting changes in position or angle into electronic pulse signals.

[0003] The integrated housing of the incremental encoder seamlessly integrates the encoder's core sensing unit with the mounting interface, protective structure, etc., into a compact, rigid, easy-to-install, and highly protective whole.

[0004] The typical housing and cover are fixed together with screws, which makes the installation process quite time-consuming.

[0005] In view of this, we propose an integrated housing for a compact incremental encoder. Utility Model Content

Multiple fixing blocks are fixed in a ring array on the peripheral wall of the shell. Multiple elastic rods are fixed in a ring array on the fixing ring. Multiple locking blocks are fixed to one end of the elastic rods respectively. The locking block is triangular in shape. The inclined surface of the locking block is squeezed open along the fixing block. The longitudinal vertical surface of the locking block contacts and limits the movement with the side of the fixing block.

[0009] Preferably, the threaded section of the peripheral wall of the housing is threaded with a threaded ring, and an annular track is provided on one side of the threaded ring.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides two embodiments.

[0026] Example 1

[0027] Please see Figures 1 to 4 An integrated housing for a compact incremental encoder includes a housing 100 and a cover 200. The core sensing unit of the incremental encoder is located inside the housing 100, and the shaft connected to the core sensing unit passes through the cover 200. The housing 100 and the cover 200 are fixed together by a connecting structure 300.

[0028] The connecting structure 300 includes a fixing ring 301, an elastic rod 304, a locking block 305, and a fixing block 306. The fixing ring 301 is sleeved on the shell cover 200. Multiple fixing blocks 306 are fixed in a ring array on the periphery of the shell 100. Multiple elastic rods 304 are fixed in a ring array on the fixing ring 301. Multiple locking blocks 305 are respectively fixed to one end of the elastic rod 304. The locking block 305 is triangular. The inclined surface of the locking block 305 is squeezed open along the fixing block 306. The longitudinal vertical surface of the locking block 305 contacts and limits the movement with the side of the fixing block 306.

[0029] When housing 100 and cover 200 are docked, the core sensing unit of the incremental encoder extends into housing 100 for positioning. The inclined surface of the locking block 305 contacts the fixing block 306. As the locking block 305 continues to be pushed, the inclined surface of the locking block 305 is lifted as it passes along the fixing block 306. The elastic rod 304 bends until the inclined surface of the locking block 305 passes the fixing block 306. The inclined surface of the locking block 305 is no longer lifted. The elastic rod 304 rebounds and drives the locking block 305 to move back. The longitudinal vertical surface of the locking block 305 contacts the side of the fixing block 306. At this time, housing 100 and cover 200 are docked and fixed.

[0030] This utility model, by setting a fixing ring 301, an elastic rod 304, a locking block 305, and a fixing block 306, has the advantages of being able to fix the housing 100 and the cover 200 when they are connected, resulting in high installation efficiency. It solves the problem that the housing 100 and the cover 200 are usually fixed with screws, which is time-consuming during the installation process.

[0031] Example 2

[0032] Please see Figures 1 to 5An integrated housing for a compact incremental encoder is disclosed. A threaded ring 302 is threaded onto the threaded section of the housing 100's circumferential wall. An annular track 303 is provided on one side of the threaded ring 302, and multiple sliders are slidably mounted on the annular track 303. Connecting rods 307 are fixed to each slider, and a push block 308 is fixed to one end of each connecting rod 307. The top of the push block 308 contacts the inclined surface of a locking block 305. The longitudinal distance by which the locking block 305 is pushed by the push block 308 is greater than the longitudinal distance between the vertical surface of the locking block 305 and the side surface of the fixing block 306. After being pushed up by the push block 308, the locking block 305 can exceed the fixing block 306 without affecting the separation of the housing 100 and the cover 200.

[0033] When it is necessary to separate the housing 100 and the cover 200, rotate the threaded ring 302. The threaded ring 302 moves along the housing 100, pushing the connecting rod 307 to move. Under the action of the annular track 303, the rotation of the threaded ring 302 will not cause the connecting rod 307 to rotate. The push block 308 is pushed by the connecting rod 307. The push block 308 pushes the locking block 305 along the inclined surface of the locking block 305 until the locking block 305 is completely lifted, so that the housing 100 and the cover 200 can be separated.

[0034] This utility model, by setting a threaded ring 302, annular track 303, connecting rod 307 and push block 308, has the advantages of quickly separating the locking block 305 from the fixing block 306 and facilitating the disassembly of the housing 100 and the cover 200.

[0035] In this embodiment, the top of the push block 308 is inclined, and the inclined surface of the top of the push block 308 is in contact with the inclined surface of the locking block 305. When the inclined surface of the top of the push block 308 contacts the inclined surface of the locking block 305, the top of the push block 308 smoothly pushes the locking block 305 up.

[0036] In this embodiment, a guide rod 309 is provided on the push block 308. One end of the guide rod 309 is fixed to the fixing block 306, and the push block 308 moves along the guide rod 309 to maintain stability. The other end of the guide rod 309 is fixed with a limit block 3010, which limits the distance the push block 308 moves, so that the top inclined surface of the push block 308 will not detach from the inclined surface of the locking block 305.

[0037] Working principle: When the housing 100 and the cover 200 are docked, the core sensing unit of the incremental encoder extends into the housing 100 for positioning. The inclined surface of the locking block 305 contacts the fixed block 306. As the locking block 305 continues to push, the inclined surface of the locking block 305 is lifted up as it passes along the fixed block 306. The elastic rod 304 bends until the inclined surface of the locking block 305 passes the fixed block 306. The inclined surface of the locking block 305 is no longer lifted up. The elastic rod 304 rebounds and drives the locking block 305 to move back. The longitudinal vertical surface of the locking block 305 contacts the side of the fixed block 306. At this time, the housing 100 and the cover 200 are docked and fixed.

[0038] When separating the housing 100 and the cover 200, rotate the threaded ring 302. The threaded ring 302 moves along the housing 100, pushing the connecting rod 307 to move. Under the action of the annular track 303, the rotation of the threaded ring 302 will not cause the connecting rod 307 to rotate. The push block 308 is pushed by the connecting rod 307. The push block 308 pushes the locking block 305 up along the inclined surface of the locking block 305 until the locking block 305 is completely lifted, so that the housing 100 and the cover 200 can be separated.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
