Abstract

A fixing device for outer casing of control system of infrared induction toilet flushing device, is a fixing bracket with hexagonal socket head spring buckle, which can be mounted into a wall hole permanently using screws. The fixing bracket is an integrated pressing unit with four convex parts with a specified angle along the edges and flanges with the same convex direction matching with four concave grooves with the same angles on the outer shell. At the same time, shallow grooves are provided on the two sides of the outer shell to match with the two sides of the fixing bracket. This way the outer shell can be hung clamped on the fixing bracket up and down. And the final fixation of the outer shell is realized by a spring buckle connecting with the fixing bracket, which is prompt and convenient for assembling and disassembling.

Description

The fastening devices of infrared induction toilet flushing device control system outer cover

Affiliated technical field:

The utility model relates to a kind of washroom concealed installation is used for the infrared induction syringe control system outer cover of flushing toilet bowl in body of wall fastening devices, is a fixed mount that has Spring lock catch that can forever be installed in the wall hole.

Background technology:

At present, the outer cover mounting means of known washroom infrared induction toilet flushing device concealed installation type control system has following several: a kind of be with outer cover with four screw fixings in the wall hole, because this control system needs time-based maintenance, must screw off four screws earlier during the dismounting outer cover, consuming time longer, when maintenance is big in batches, operating efficiency is low, and screw loses easily, causes unnecessary loss, simultaneously this mounting means requires the maintenance personal to be skilled in technique, otherwise damage equipment very easily; Another kind be from the below of outer cover with a screw fixings, install inconvenient; Also having a kind of is to utilize the magnetic of magnet to install, cost height not only, and install also insecure.

Summary of the invention:

Deficiency for the outer cover mounting means that overcomes existing washroom infrared induction toilet flushing device control system, the utility model provides a kind of fixed mount, this fixed mount does not only need subsidiary screw, and load and unload efficient and convenient, the more important thing is and have only the specialized maintenance personnel to use special tool could dismantle outer cover, reduce the probability of device losses, avoid the destruction of layabout equipment.

The technical scheme that its technical problem that solves the utility model adopts is: available screw is permanently affixed at the fixed mount at edge, wall hole by four marking shape windows, this fixed mount is whole stamping parts, its edge has four to raise into certain angle and the identical flange of protrusion direction, with four groove fit that become equal angular on the outer cover, the outer cover both sides have shallow slot to cooperate with the fixed mount both sides simultaneously, outer cover can hang tag on fixed mount from top to bottom like this, the final fixing of outer cover then realized by a Spring lock catch that connects together with fixed mount, this Spring lock catch is positioned on the platform vertical with fixed mount in center, fixed mount below, curve 90 ° by a small end, big end is the stepped stem of interior hexagonal socket cap and spring formation, spring housing is on small end, and external diameter is less than interior hexagonal socket cap, the aperture that small end passes on the platform curves 90 °, and be processed into a plane with the contact with platform part, hole diameter is less than the spring external diameter, like this, make spring between interior hexagonal socket cap step and platform, be compressive state, the elastic force that produces fits tightly 90 ° of elbows and platform, slit by center, outer cover below, externally can make Spring lock catch aperture axis rotation on platform with inner hexagon spanner, because the restriction that platform and outer cover are topped bar, Spring lock catch can only rotate in 90 ° of scopes, and Spring lock catch is in unblank and locks two states along the rib body of projection by platform edges, when outer cover hangs tag on fixed mount, there is a stepped step outer cover below near the side that the rib body is arranged of platform, this step low side is equal with rib body peak, when 90 ° of elbows of Spring lock catch fully when platform is inner, outer cover and fixed mount are in unlocking condition, when 90 ° of elbows when the inclined-plane of rib body is threaded to peak, promptly screw out from platform is inner, be threaded to the step low side on the outer cover, this moment, 90 ° of elbows and step low side were partly accepting and partly rejecting state, continue rotation by step is high-end when blocking, 90 ° of elbows fully with platform on the disengaging of rib body, elastic force by spring is in the lock state outer cover and fixed mount, when needs were unblanked, the reverse rotation Spring lock catch got final product for 90 °.

The beneficial effects of the utility model are, locking mechanism and fixed mount are connected as a single entity, can permanently install, prevent loss, comparatively speaking good looking appearance is generous, and convenient disassembly is quick, is convenient to maintaining, and can only open this locking mechanism with special tool, can effectively prevent the infringement of layman equipment.

The specific embodiment:

In Fig. 1, the infrared induction control system is installed in the wall hole (16), the fixed mount (2) that is in unlocking condition as shown in Figure 3 is fixed on edge, wall hole (16) with four screws (5) by four marking shape windows (18), make the outer cover (1) that has induction window (17) a little more than wall hole (16), move metope along arrow (11) direction is parallel, be directed downwards mobile along arrow (12) again, make outer cover inboard (9), (10) four downward opening grooves locating and fixed mount (7), (8) locate four hanging tag together of side obliquely with the acutangulate flange of fixed mount, as shown in figure 11, fixed mount (2) both sides are in the shallow slot of the inner both sides of outer cover (1) simultaneously, make outer cover (1) can not about, before and after and move down, final locking is realized by Spring lock catch (3), this Spring lock catch is made of a stepped stem and a spring (4), stepped stem such as Fig. 7, Fig. 8, big end shown in Figure 9 is interior hexagonal groove, overlapping spring (4) on the small end, and pass and the platform (20) of fixed mount (2) one on a hole (23) curve 90 °, make spring (4) be in compressive state, 90 ° of elbows (24) have processed a plane with the contact with platform part, increased contact area, have only like this with special tool ability rotation spring snap close (3), avoided misoperation, and this platform edges has the rib body (22) of a projection as shown in Figure 5, this rib body peak is equal with the step low side (25) on the outer cover (1), slit (15) by the outer cover below makes Spring lock catch (3) rotate along arrow (13) direction with inner hexagon spanner (14), make 90 ° of elbows screw on step low side on the outer cover (1) along the rib body, up to being blocked by step high-end (26), this moment, 90 ° of elbows and rib body broke away from fully, the elastic force that produces by spring (4) can lock together outer cover (1) and fixed mount (2), as shown in Figure 5.

In Fig. 3, fixed mount (2) is in unlocking condition with outer cover (1), inner, the rib body low side of the platform (20) of 90 ° of elbows of Spring lock catch this moment (3) on fixed mount (2), break away from fully with the step on the outer cover (1), be convenient to install, relatively stable at the effect upper/lower positions of spring (4), can only with special tool Spring lock catch (3) be rotated by slit (15), and be subjected to the restriction of shoulder block on the platform (21), Spring lock catch (3) can only folk prescription to rotation, avoid maloperation.

In Fig. 5, fixed mount (2) is in the lock state with outer cover (1), the 90 ° of elbows and the rib body (22) of Spring lock catch this moment (3) break away from fully, under the effect of spring (4) with outer cover (1) on closely joining of step low side (25), because the restriction of step high-end (26), the Spring lock catch of this state also can only folk prescription to rotation, simple to operation.
