Abstract
Description
Technical Field
[0001] This utility model relates to the field of instrument housing technology, and in particular to an instrument housing for indication. Background Technology
[0002] An instrument housing is a protective enclosure for the instrument panel. When using equipment that requires an instrument panel, it is usually necessary to install an enclosure on the instrument panel and check whether the instrument panel has reached the protection threshold by using the protection pointer on the instrument housing and the pointer on the instrument panel itself to prevent accidents from occurring.
[0003] Currently, there are two types of protection pointer designs on the instrument panel housing: sticker type and plastic pointer type. The plastic pointer type allows users to set the protection threshold by directly rotating the pointer, thus enabling them to check whether the instrument panel protection has reached the set value.
[0004] Because the plastic protective pointer is usually installed inside the protective shell and connected to the outside by a snap-fit, workers need to use their fingernails or other tools to rotate the plastic protective pointer. When there are no fingernails or tools, it is difficult to rotate the protective pointer, and there is still room for improvement. Utility Model Content
[0005] To facilitate the rotation of the protective pointer by staff, this utility model provides an instrument housing for indication.
[0006] This utility model provides a housing for an indicating instrument, employing the following technical solution:
[0007] An instrument housing for indication includes a housing, a pointer, and a cover for mounting the pointer. The pointer is provided with a snap-fit post, and a snap-fit block is provided on the side of the snap-fit post away from the pointer surface. Both the snap-fit block and the snap-fit post are provided with relief grooves for deformation of the snap-fit post and the snap-fit block. The cover is provided with a cover through hole for snap-fit of the snap-fit block and for mounting of the snap-fit post.
[0008] The snap-fit block is provided with a protective cover, and an entry block is provided on the side of the protective cover near the snap-fit block. The entry block cooperates with the retraction groove, and a rotating handle for rotating the pointer is installed on the protective cover.
[0009] By adopting the above technical solution, a locking post and a locking block are set on the pointer to install the pointer on the housing. Both the locking post and the locking block are provided with a relief groove. The protective cover is installed on the locking post and cooperates with the insertion block and the relief groove. A rotating handle is installed on the protective cover. By rotating the rotating handle, the pointer is rotated, so that the operator can easily adjust the angle of the pointer.
[0010] Optionally, the protective cover is provided with a fixing shaft, and the snap-fit block and the snap-fit post are provided with through holes for the fixing shaft to be inserted.
[0011] By adopting the above technical solution, a fixed shaft is set on the protective cover, and through holes are opened on the snap-fit block and snap-fit post, so that the fixed shaft can be inserted into the through holes. This reduces the possibility of the snap-fit post and snap-fit block deforming and detaching from the cover after being installed on it.
[0012] Optionally, the surface of the fixed shaft is provided with a fixed circular block, and the inner wall of the snap-fit post is provided with a snap-fit groove for the fixed circular block to snap into.
[0013] The fixed shaft has a cavity inside, and the fixed shaft has a deformation groove for the displacement and deformation of the fixed circular block. The deformation groove is connected to the cavity.
[0014] By adopting the above technical solution, a fixing block is provided on the surface of the fixing shaft. The fixing block deforms through the cavity and the deformation groove, and a slot is provided on the inner wall of the snap-fit post. This allows the fixing shaft to be fixedly installed in the snap-fit post through the cooperation of the fixing block and the slot, reducing the possibility of the fixing shaft falling out of the slot.
[0015] Optionally, the fixed shaft is provided with an elastic strip that abuts and presses against the fixed circular block, and the elastic strip is located inside the cavity.
[0016] By adopting the above technical solution, after the fixed shaft is on the snap-fit post, an elastic strip is set in the cavity. The elastic strip deforms and abuts against the fixed round block, thereby improving the stability of the fixed shaft installation by deforming the fixed round block outward through the deformation force of the elastic strip itself.
[0017] Optionally, a mounting post is provided on the fixed shaft, and a through hole is provided on the elastic strip for the mounting post to pass through. A sealing block for fixing the elastic strip is provided on the side of the mounting post away from the fixed shaft.
[0018] By adopting the above technical solution, the elastic strip is installed and fitted through the perforation of the elastic strip and the mounting post, and then fixed by the sealing block after the fit is completed, so that the elastic strip can be fixed on the fixed shaft, thereby reducing the possibility of the elastic strip moving axially and detaching from the cavity of the fixed shaft.
[0019] Optionally, the fixed circular block is provided with mounting holes for mounting the elastic strip.
[0020] By adopting the above technical solution, an assembly hole is opened on the fixed cylinder, and the elastic strip is installed in the assembly hole, so that the elastic strip can be accurately installed on the fixed cylinder, thereby reducing the possibility of the elastic strip moving axially and leaving the fixed cylinder.
[0021] Optionally, the rotating handle is provided with a fixing post, and the protective cover is provided with fixing holes for fixing the fixing post.
[0022] By adopting the above technical solution, the rotating handle can be installed on the protective cover by rotating the fixing post on the handle and the fixing hole on the protective cover, so that the operator can easily rotate the pointer after installing the rotating handle.
[0023] Optionally, mounting seats are provided on both sides of the housing for mounting the housing, and the mounting seats are provided with countersunk holes for bolt installation.
[0024] By adopting the above technical solution, mounting seats are provided on both sides of the housing, and countersunk holes are provided on the mounting seats. When it is necessary to install the instrument housing on the wall, the instrument panel can be fixed to the wall by passing bolts through the countersunk holes.
[0025] Optionally, an adhesive washer corresponding to the countersunk hole is provided on the side of the mounting base away from the housing, and a spacer is provided on the side of the adhesive washer away from the mounting base.
[0026] By adopting the above technical solution, when it is necessary to install the instrument housing, the isolation piece on the adhesive gasket can be removed first, and the instrument housing can be pre-installed on the wall. Thus, the pre-fixation before installing the instrument panel is achieved by using the adhesive gasket, which facilitates the positioning by the staff.
[0027] Optionally, the mounting base has an annular groove for mounting the adhesive washer and the isolation piece.
[0028] By adopting the above technical solution, the adhesive gasket and the spacer are installed in the annular groove opened in the mounting base, so that the adhesive gasket can be protected by the annular groove when it is not in use.
[0029] In summary, this application includes at least one of the following beneficial technical effects:
[0030] 1. The pointer angle can be easily adjusted by rotating the handle;
[0031] 2. This reduces the likelihood of the locking pins and blocks deforming and detaching after being installed on the housing by fixing the shaft;
[0032] 3. This allows for pre-fixation of the instrument panel before installation using adhesive washers, facilitating positioning by staff. Attached Figure Description

[0044] When it is necessary to mount the instrument housing on the wall, the instrument housing can be mounted on the wall by passing bolts through the countersunk holes 24 on the mounting base 23.
[0045] refer to Figure 2An annular groove 27 is provided at the bottom of the mounting base 23, and an adhesive washer 25 and a spacer 26 are provided at the bottom of the mounting base 23. The adhesive washer 25 and the spacer 26 are installed in the annular groove 27. The spacer 26 is removed, and the housing 1 can be fixed to the wall by the adhesiveness of the adhesive washer 25.
[0046] Reference Figure 3 and Figure 4 A pointer 2 is installed below the housing 3. A housing through-hole 7 is located at the center of the housing 3. A snap-fit post 4 and a snap-fit block 5 are integrally injection molded onto the pointer 2. The snap-fit block 5 is frustoconical. To allow the snap-fit post 4 and snap-fit block 5 to be installed within the housing through-hole 7, a relief groove 6 is provided on the snap-fit post 4 and snap-fit block 5. When the pointer 2 is installed onto the housing 3, the snap-fit post 4 and snap-fit block 5 are vertically inserted into the housing through-hole 7. At this time, the snap-fit block 5 and snap-fit post 4 are compressed and deformed towards the relief groove 6, returning to their original shape when snapped into the housing 1.
[0047] refer to Figure 3 and Figure 5 A protective cover 8 is provided above the snap-fit block 5, which completely encloses the snap-fit block 5. A rotating handle 10 is provided on the surface of the protective cover 8 away from the shell 3. In order to make the pointer 2 rotate when the rotating handle 10 is rotated, an entry block 9 is provided below the protective cover 8. The entry block 9 cooperates with the relief groove 6. When installing the protective cover 8, the protective cover 8 and the snap-fit block 5 are flush and cooperated by aligning the entry block 9 with the relief groove 6.
[0048] When it is necessary to rotate pointer 2, simply rotate the rotating handle 10 to rotate pointer 2.
[0049] refer to Figure 3 and Figure 5 In order to reduce the possibility of the snap-fit post 4 and snap-fit block 5 falling out of the through hole 7 of the housing, a fixing shaft 11 is provided on the protective cover 8, and through holes 12 are provided on the snap-fit post 4 and snap-fit block 5 for installing the fixing shaft 11 into the snap-fit post 4.
[0050] refer to Figure 6 To enable the rotating handle 10 to be mounted on the protective cover 8, several fixing posts 21 are provided on the rotating handle 10, and several fixing holes 22 corresponding to the fixing posts 21 are provided on the protective cover 8. The rotating handle 10 inserts the fixing posts 21 into the fixing holes 22, thereby mounting the rotating handle 10 on the protective cover 8.
[0051] refer to Figure 6 and Figure 7To allow the fixed shaft 11 to be installed inside the locking post 4, a fixing block 13 is provided on the fixed shaft 11. A locking groove 14 is formed on the inner wall of the locking post 4, circumferentially surrounding the fixed shaft 11, and the fixing block 13 engages with the locking groove 14.
