Description

Technical Field

[0001] The present application relates to the technical field of ammeters, and in particular to an embedded ammeter housing. Background Art

[0002] An ammeter is an instrument used to measure the current in AC and DC circuits and is widely used in various industrial control measurement industries.

[0003] Most of the small panel ammeters popular on the market now have a pair of conductive columns and a pair of mounting columns, a total of 4 copper columns. In this way, users need to screw and install them in 4 times when using them, which is time-consuming and laborious. In addition, most ammeters are externally mounted, which affects the overall aesthetics of the equipment; in order to improve the aesthetics, some companies have improved the ammeter into an embedded type, that is, embedded in the side wall of the equipment, with only the dial exposed, and countersunk bolts are provided on both sides of the front dial. The countersunk bolts penetrate the dial and are screwed on the inner wall of the equipment to fix the ammeter. Although this method reduces the leakage of the ammeter and improves the aesthetics of the installation. However, when the ammeter needs to be inspected internally, in many cases, it is necessary to screw and remove the countersunk bolts one by one, remove the ammeter from the equipment, and then open the ammeter dial; after the inspection, the ammeter needs to be re-embedded and the countersunk bolts are screwed one by one. The process is cumbersome and time-consuming.

[0004] To this end, the present application provides an embedded ammeter housing to improve the efficiency of disassembly and assembly of the ammeter during maintenance. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the attached examples of the present application Figure 1-6 , the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0026] In order to solve the problems existing in the prior art, the present embodiment provides an embedded ammeter housing, including an installation shell 1, a packaging shell cover 2 is detachably installed at the front end of the installation shell 1, bolts 4 are symmetrically inserted on both sides of the packaging shell cover 2, and the end 7 and the screw 8 of the bolt 4 are separable.

[0027] Details of the principles of this program:

[0028] A housing of an embedded ammeter comprises a mounting shell 1, wherein the mounting shell 1 is divided into an embedded part for embedding a device on the rear side and a mounting part for installing a dial 3 on the front side. The side wall of the device is provided with an embedded hole which is completely matched with the outer wall of the embedded part on the rear side of the mounting shell 1, and threaded holes are symmetrically arranged on the sides of the port of the embedded hole. The end face of the mounting part at the front end of the mounting shell 1 is detachably provided with a packaging shell cover 2 via a countersunk screw 6. The front end of the packaging shell is opened to expose the dial 3. The packaging shell cover 2 is symmetrically provided with countersunk holes corresponding to the threaded holes. Both sides of the packaging shell are symmetrically provided with insertion holes concentric with the countersunk holes. Bolts 4 are inserted into the countersunk holes, and the bolts 4 pass through the insertion holes. The end 7 and the screw 8 of the bolt 4 are separable. The diameter of the screw 8 of the bolt 4 is smaller than the minor diameter of the countersunk hole, and the end 7 of the bolt 4 is larger than the minor diameter of the countersunk hole and smaller than the major diameter of the countersunk hole.

[0029] When in use, insert the embedded part of the rear side of the package shell into the embedded hole, then insert the bolt 4, screw the bolt 4, and the bolt 4 gradually goes deep into the threaded hole to fasten the installation shell 1 to the outer wall of the device. The embedded installation reduces the external leakage of the entire ammeter, and only the dial 3 is exposed, just like the device itself, and the form is more beautiful.

[0030] When disassembling for inspection, the end 7 of the bolt 4 is removed, the package cover 2 can be removed, and then the dial 3 can be removed without removing the entire device.

[0031] In a further embodiment of the present solution, two groups of mounting posts and conductive posts 5 are symmetrically provided at the rear end of the mounting housing 1, and the mounting posts and conductive posts 5 of the same group are integrally formed, thereby reducing the number of installation steps for the user and improving installation efficiency.

[0032] In a further embodiment of the present scheme, the rear end portion of the mounting shell 1 is in the shape of an inverted arch, and the embedded hole opened on the equipment is also in the shape of an arch, which increases the accommodating volume inside the mounting shell 1 and limits the position during the embedded installation, making it easier for the bolt 4 to dock with the threaded hole.

[0033] In a further embodiment of the present scheme, a structure is provided in which the end 7 of the first bolt 4 is separated from the screw rod 8: a first insertion hole is provided at the end of the screw rod 8, a first slot 11 is provided on the inner wall of the insertion hole, an open first arc-shaped groove 12 is provided at the bottom end of the first slot 11, an insertion rod 9 is provided at the bottom end of the end 7, and a first insert block 10 cooperating with the first slot 11 is provided on the side wall at the bottom end of the insertion rod 9.

[0034] When in use, align the first insert 10 with the first notch 11 and insert the plug 9 into the first jack, then use a wrench to screw the end 7, the first insert 10 deflects in the first arc groove 12 and abuts against the side wall of the first arc groove 12, thereby rotating against the screw 8, so that the screw 8 is screwed into the threaded hole, and as the screw 8 is tightened, the end 7 is tightly pressed against the countersunk hole, thereby fixing the ammeter. When disassembling, screw the end 7 in the opposite direction to the previous one, and after the screw 8 is slightly loosened, the end 7 can deflect relative to the screw 8, so that the first insert 10 is aligned with the first notch 11, and the end 7 can be pulled out. At this time, the package shell cover 2 has no limit, and the dial 3 can be directly disassembled without removing the entire body.

[0035] In a further embodiment of the present scheme, the present embodiment provides a second structure in which the end 7 of the bolt 4 is separated from the screw rod 8: a fixing column 13 is provided at the end of the screw rod 8, a second slot 15 is provided on the side wall of the fixing column 13, an open second arc groove 16 is provided at the bottom end of the second slot 15, a sleeve 17 cooperating with the fixing column 13 is provided at the bottom end of the end 7, and a second insert 14 cooperating with the second slot 15 is provided at the bottom of the inner wall of the sleeve 17.

[0036] When in use, align the second insert 14 with the second notch 15 and insert the fixing column 13 into the sleeve 17, then use a wrench to screw the end 7, the second insert 14 deflects in the second arc groove 16 and abuts against the side wall of the second arc groove 16, thereby rotating against the screw 8, so that the screw 8 is screwed into the threaded hole, and as the screw 8 is tightened, the end 7 is tightly against the countersunk hole, thereby fixing the ammeter. When disassembling, screw the end 7 in the opposite direction to the previous direction, and after the screw 8 is slightly loosened, the end 7 can deflect relative to the screw 8, so that the second insert 14 is aligned with the second notch 15, and the end 7 can be pulled out. At this time, the package cover 2 has no limit, and the customer can directly disassemble the dial 3 without disassembling the entire device.

[0037] In a further embodiment of the present scheme, the end cap 7 is hexagonal and has an inner hexagonal hole at the upper end. At this time, it is disassembled and assembled by a hexagonal wrench, and the major diameter of the countersunk hole is adaptively reduced.

[0038] In a further embodiment of the present solution, the installation housing 1 is integrally formed by injection molding, which reduces assembly time and improves ease of use compared to dispersed injection molding.
