Description

Technical Field

[0001] The present application relates to the technical field of timers, and in particular to an electronic timer housing installation structure. Background Art

[0002] Electronic timers can be used to turn electronic devices on or off at a scheduled time. Electronic timers achieve timing actions through electronic circuits and are usually on-delay timers.

[0003] The electronic timer includes a housing, a circuit board and a display. The housing includes an upper housing and a lower housing. The upper housing and the lower housing are connected to form a cavity for placing the circuit board and the display. In the related art, in order to facilitate the connection between the upper housing and the lower housing, a card slot is provided on the inner wall of the upper housing, and a card block inserted into the card slot is provided on the outer wall of the lower housing. When fixing the upper housing and the lower housing, the lower housing is inserted into the upper housing as a whole and the card block is connected to the card slot for pre-fixation, and then the upper housing and the lower housing are fixed together by screws.

[0004] With regard to the above-mentioned related technologies, when the circuit board or display is damaged and needs to be repaired, the upper shell and the lower shell need to be opened. However, since the lower shell is inserted into the upper shell as a whole and the card block is engaged in the card slot, it is not easy to apply force to pull the lower shell out of the upper shell for disassembly and repair. Utility Model Content

[0005] In order to facilitate the disassembly and maintenance of an electronic timer, the present application provides an electronic timer housing installation structure.

[0006] The present application provides an electronic timer housing installation structure, which adopts the following technical solution:

[0007] An electronic timer shell installation structure includes a front shell and a rear shell, wherein a mounting groove for inserting the rear shell is provided on a side of the front shell close to the rear shell, a magnetic strip is provided in the mounting groove, an iron sheet for engaging with the magnetic strip is provided on a side of the rear shell close to the front shell, a screw column is provided at the bottom of the mounting groove, and a through hole for a screw to pass through and be threadedly installed on the screw column is provided on a side of the rear shell away from the front shell.

[0008] By adopting the above technical solution, first, when installing the front shell and the rear shell, the rear shell and the front shell can be pre-positioned by the attraction between the magnetic strip and the iron sheet, and then the front shell and the rear shell are fixed by screws. When the electronic timer needs to be disassembled for maintenance, the maintenance personnel first remove the screws from the front shell, and then shake the front shell with their hands. After the rear shell is shaken, the iron sheet is more likely to lose the attraction with the magnetic strip, thereby making the rear shell detachable from the front shell.

[0009] Optionally, a convex strip for easy pinching is provided on a side of the rear shell facing away from the front shell.

[0010] By adopting the above technical solution, when removing the rear shell from the front shell, the maintenance personnel can pinch the convex strip with two fingers and then forcefully pull the rear shell out of the installation groove, thereby making the removal more convenient.

[0011] Optionally, friction lines are provided on the side walls of the convex strips to increase the friction between the hand and the convex strips.

[0012] By adopting the above technical solution, the setting of the friction lines increases the friction between the fingers and the convex strips, and slipping is not likely to occur when the rear shell is pulled off.

[0013] Optionally, a hand-pinching groove for fingers to enter is opened on a side of the rear shell body facing away from the front shell body, and the convex strip is arranged at the bottom of the hand-pinching groove and the convex strip does not protrude from the hand-pinching groove.

[0014] By adopting the above technical solution, the convex strip does not protrude from the hand-pinching groove, so that it is not easy for a bulge to appear on the side of the rear shell away from the front shell, thereby causing interference when installing the electronic timer.

[0015] Optionally, an abutment plate for limiting the insertion depth of the rear shell body is provided at the bottom of the installation slot, and the magnetic strip is provided on the abutment plate.

[0016] By adopting the above technical solution, after the rear housing is inserted into the installation slot, it will abut against the abutment plate to be limited, thereby preventing the circuit board in the installation slot from being squeezed and damaged.

[0017] Optionally, the abutment plate is provided with a groove for the magnetic strip to be placed in.

[0018] By adopting the above technical solution, the abutment plate is placed in the groove, which increases the contact area between the magnetic strip and the abutment plate and improves the stability of the magnetic strip after installation.

[0019] Optionally, a prying groove is provided on the side wall of the rear shell body for facilitating the insertion of a tool to pry the rear shell body off the front shell body, and the prying groove penetrates the rear shell body at a side facing away from the front shell body.

[0020] By adopting the above technical solution, if the rear shell body is difficult to be pulled out from the installation groove by the convex strip, the maintenance personnel can use a tool to insert into the prying groove to lift out the rear shell body. The prying groove is used as an alternative solution, so that there are multiple options for disassembly.

[0021] Optionally, a plurality of prying grooves are arranged at intervals on the rear shell body.

[0022] By adopting the above technical solution, when a tool is inserted into a prying groove to pry the rear shell, it may only pry up this part and it is not easy to pick out the rear shell by hand. Therefore, maintenance personnel can pry open different positions through multiple prying grooves, thereby making it more convenient to remove the rear shell.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] First, when installing the front shell and the rear shell, the rear shell and the front shell can be pre-positioned by the attraction of the magnetic strip and the iron sheet, and then the front shell and the rear shell are fixed by screws. When the electronic timer needs to be disassembled for maintenance, the maintenance personnel first remove the screws from the front shell, and then shake the front shell with their hands. After the rear shell is shaken, the iron sheet is more likely to lose the attraction with the magnetic strip, so that the rear shell can be removed from the front shell;

[0025] When removing the rear housing from the front housing, the maintenance personnel can pinch the convex strip with two fingers and then forcefully pull the rear housing out of the installation slot. The setting of the friction pattern increases the friction between the fingers and the convex strip, and it is not easy to slip when pulling out the rear housing;

[0026] If the rear housing is difficult to be pulled out from the installation groove by the convex strip, the maintenance personnel can use a tool to insert into the prying groove to lift out the rear housing. The prying groove is used as an alternative solution, so that there are multiple options for disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses an electronic timer housing installation structure. Figure 1 The electronic timer housing installation structure includes a front housing 1 and a rear housing 2. The front housing 1 and the rear housing 2 are first pre-positioned by magnetic attraction and then fixed by screws. When removing the rear housing 2 from the front housing 1, first remove the screws. Since the front housing 1 and the rear housing 2 are still connected together by magnetic attraction, it is only necessary to use a little force to pull the rear housing 2 off the front housing 1 to release the magnetic attraction. This makes the installation or removal of the front housing 1 and the rear housing 2 more convenient.

[0034] Reference Figure 1 and Figure 2 A mounting groove 11 is provided on the side of the front housing 1 close to the rear housing 2. The rear housing 2 is inserted into the mounting groove 11, and the outer peripheral wall of the rear housing 2 abuts against the groove wall of the mounting groove 11. An abutment plate 12 is integrally formed at the bottom of the mounting groove 11. Two abutment plates 12 are provided. The two abutment plates 12 are symmetrically arranged, and the two abutment plates 12 abut against two corresponding groove walls respectively. After the side of the rear housing 2 close to the front housing 1 is inserted into the mounting groove 11 and moves a certain distance, it will abut against the abutment plate 12 and be limited so as not to continue to move.

[0035] Reference Figure 2 and Figure 3 A groove 121 is provided on the side of the abutment plate 12 close to the rear shell 2, and a magnetic strip 13 is glued into the groove 121 by strong glue. The side of the magnetic strip 13 facing away from the bottom of the groove 121 is flush with the side of the abutment plate 12 close to the rear shell 2. A placement groove 21 is provided on the side of the rear shell 2 close to the front shell 1, and an iron sheet 22 is glued into the placement groove 21 by strong glue. The iron sheet 22 and the magnetic strip 13 are attracted to each other. It is worth noting that the magnetic force of the magnetic strip 13 is small, so the attraction between the magnetic strip 13 and the iron sheet 22 is small, and the rear shell 2 is relatively easy to be pulled out of the installation groove 11.

[0036] Reference Figure 2 and Figure 4 A hand-gripping groove 23 for fingers to enter is provided on the side of the rear housing 2 facing away from the front housing 1, and a convex strip 24 for fingers to pinch is integrally formed at the bottom of the hand-gripping groove 23, and the convex strip 24 does not protrude from the hand-gripping groove 23. When removing the rear housing 2, pinch the convex strip 24 with two fingers and then pull it outward with force.

[0037] The side wall of the convex strip 24 is provided with a friction pattern 25 for increasing the friction between the finger and the convex strip 24 to facilitate pulling out the rear housing 2 .

[0038] Reference Figure 2 and Figure 4A prying groove 26 is provided on the outer wall of the rear housing 2, and the side of the prying groove 26 facing away from the front housing 1 penetrates the rear housing 2. When it is difficult to pull the rear housing 2 out of the installation slot 11 by pinching the convex strip 24 with fingers, a tool can be inserted into the prying groove 26 to pry out the rear housing 2. In addition, a plurality of prying grooves 26 are provided on the rear housing 2, and the plurality of prying grooves 26 are arranged at intervals circumferentially on the rear housing 2, so as to facilitate prying out various positions of the rear housing 2 from the installation slot 11.

[0039] In order to improve the stability after the rear housing 2 is connected to the front housing 1, a screw column 14 is integrally formed at the bottom of the mounting groove 11, and a through hole 27 penetrating the rear housing 2 is provided on the side away from the front housing 1, and the position of the through hole 27 corresponds to the screw column 14. The screw is inserted into the through hole 27 and the threaded end of the screw is threadedly mounted on the screw column 14.

[0040] The implementation principle of the electronic timer shell installation structure of an embodiment of the present application is: when the electronic timer needs to be disassembled for maintenance, the maintenance personnel first remove the screws from the front shell 1, then pinch the convex strip 24 with two fingers and then pull the rear shell 2 out from the installation groove 11 to prevent the iron sheet 22 from being attracted to the magnetic strip 13, thereby making it easier to disassemble and repair.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
