Abstract

The utility model provides a mechanical type timer shell and mounting panel fitting piece, includes shell and mounting panel, the reason has T shape to turn round the foot on two walls of shell symmetry, have on the mounting panel with the slotted hole that the foot corresponds is turned round to T shape, the foot is turned round to T shape on the shell is worn through the slotted hole of mounting panel to the configuration is after the cooperation the T shape of wearing through the slotted hole is turned round the foot and is twisted round an angle, and it sends the horizontal pole of foot is turned round to T shape with the slotted hole is into the fork form. The utility model discloses the combination is in mechanical type timer, and the convenience is installed the timer in electrical apparatus, the utility model discloses simple structure, excellent in use effect.

Description

Mechanical timer shell and mounting panel fitting piece

Technical Field

The utility model relates to a timing device, especially shell and mounting panel cooperation structure of mechanical type timer.

Background

Mechanical timers are usually installed on appliances to control the operation time of the appliance, such as a knob-controlled microwave oven, a knob is manually turned, contacts are lapped, the microwave oven is powered on to operate, the timer runs, the knob slowly rotates in the process, the timer runs out, the contacts are disconnected and the microwave oven stops operating.

Mechanical timers are typically mounted to an appliance by a mounting plate connection, the mounting plate acting as a bridge to which the two are connected. As shown in fig. 1, the mounting plate in the prior art is generally connected to the timer housing through an inverted L-shaped torsion pin a on the timer housing, and the mounting plate is then connected to the electric appliance. However, the press-in of the timer knob often causes the mounting plate to fall off, resulting in complaints from users.

SUMMERY OF THE UTILITY MODEL

The utility model discloses solve among the prior art mechanical timer and pass through the mounting panel and be connected with electrical apparatus, the problem that the mounting panel drops easily provides for this reason the utility model discloses a mechanical timer shell and mounting panel fitting piece, timer shell combine firmly with the mounting panel in this fitting piece, and the mounting panel is difficult for droing in the timer uses.

In order to solve the problem, the utility model discloses a technical scheme include shell and mounting panel, and its special character is the reason has T shape to turn round the foot on two walls of shell symmetry, have on the mounting panel with the slotted hole that the foot corresponds is turned round to T shape, the foot is turned round to T shape on the shell passes through the slotted hole of mounting panel to the configuration is after the cooperation the T shape of passing through the slotted hole is turned round the foot and is twisted round an angle, and it sends the horizontal pole of foot is turned round to T shape with the slotted hole becomes the fork shape.

The upper edges of the two symmetrical walls of the shell are provided with T-shaped twisting feet, namely the upper edge of each wall of the two symmetrical walls of the shell is provided with two T-shaped twisting feet which are mutually spaced, and correspondingly, each end of two ends of the mounting plate is provided with a slotted hole corresponding to the T-shaped foot.

The T-shaped twisting feet on the symmetrical upper edges of the two walls of the shell are preferably cutting processing remaining twisting feet which are integrally connected with the upper edges of the two walls of the shell.

The T-shaped torsion legs are twisted at an angle as a result of the operation of the conventional assembly process.

The cross bar of the T-shaped twisting foot is named as the occasion name relative to the straight bar of the T-shaped twisting foot. The cross bar of the T-shaped twisting foot is crossed with the corresponding slotted hole, so that the direction parts of the two ends of the cross bar are buckled and pressed on the plate body parts of the two sides of the slotted hole of the mounting plate.

The utility model discloses because be equipped with the T shape on the shell and turn round the foot, this T shape is turned round the foot and is worn through the corresponding slotted hole of mounting panel to twisted round an angle, the horizontal pole both ends part that the foot was turned round to the T shape withstands in the plate body part of mounting panel slotted hole both sides, and it compares to turn round the foot with the L shape of falling prior art, the utility model discloses well shell has increased one time with the bonding strength of mounting panel to the combination is more stable, so the utility model discloses cooperate and install behind the electrical apparatus in mechanical type timer, the mounting panel is difficult for droing.

The present invention will be described in detail with reference to the accompanying drawings and the following detailed description.

Detailed Description

The utility model provides a mechanical type timer shell and mounting panel fitting piece, includes shell 2 and mounting panel 1, and the reason has two T shape wrench feet 21 of mutual interval on every wall of two walls of shell 2 symmetry, has on the mounting panel 1 with slotted hole 11 that T shape wrench feet 21 corresponds, and T shape wrench feet 21 on the shell 2 crosses the slotted hole 11 of mounting panel to the configuration is after the cooperation T shape wrench feet 21 that crosses slotted hole 11 is twisted an angle, and the horizontal pole 211 that causes T shape wrench feet 21 with slotted hole 11 becomes the fork form. So, the plate body part in 11 both sides of mounting panel slotted hole is withheld at the horizontal pole 211 both ends part of foot is turned round to T shape, compares with the foot is turned round to the L shape of prior art, the utility model discloses well shell has increased one time with the bonding strength of mounting panel to it is more stable to combine.

Claims

1. The utility model provides a mechanical type timer shell and mounting panel fitting piece, includes shell (2) and mounting panel (1), characterized by the reason is gone up to two walls of shell (2) symmetry has T shape and turns round foot (21), have on the mounting panel with slotted hole (11) that the foot corresponds are turned round to T shape, the foot is turned round to T shape on the shell and is worn through the slotted hole of mounting panel to the configuration is after the cooperation the foot is turned round to T shape through the slotted hole is twisted round an angle, and it sends to T shape turn round the horizontal pole of foot with the slotted hole becomes the cross form.

2. The fitting according to claim 1, characterized in that the upper edges of the two symmetrical walls of the housing (2) are provided with T-shaped legs (21), which means that the upper edges of each of the two symmetrical walls of the housing are provided with two T-shaped legs spaced apart from each other, and that each of the two ends of the mounting plate is provided with a slot corresponding to the T-shaped leg.
