The invention discloses a kind of Socket casing, including drain pan and the cap being arranged at the drain pan upper opening, one end of the cap is hinged by one end of bearing pin and the drain pan, the other end of the cap is connected by interface arrangment with the drain pan, it is characterized in that, gudgeon is provided with the cap, the bearing pin is located in the perforation of the gudgeon, flexible boss is molded on the periphery wall of the gudgeon, position corresponding with the gudgeon has arcwall face on the drain pan, stopper slot is formed on the arcwall face, when the cap is in an open position, the elastic boss is engaged with the stopper slot.It is rational in infrastructure in the present invention, do not closed when cap is in the open position because of self gravitation effect, and also it is easy to operate during cap opening, cap locks reliable after covering.

Description

Socket casing

Technical field

The present invention relates to a kind of Socket casing, belongs to construction of switch design field.

Background technology

Existing Socket casing includes drain pan and the cap being arranged at the drain pan upper opening, one end of the cap It is hinged by one end of bearing pin and the drain pan, the other end of the cap is connected by interface arrangment with the drain pan, described Interface arrangment includes hole clipping and the buckle coordinated with hole clipping.The problem of above-mentioned Socket casing is present be：(1) due to not set to cap The position limiting structure being set effective, therefore easily closed after cap opening under self gravitation effect；(2) design of interface arrangment is not Very rationally, need firmly to pry open buckle with instrument when the cap is opened, operation is relatively elaborate, and easily causes buckle fracture.

The content of the invention

On the other hand, the present invention is intended to provide a kind of Socket casing rational in infrastructure, its upper shell cover will not when being in the open position Closed under self gravitation effect, so as to be advantageous to plug and socket grafting.

Realizing the technical scheme of the object of the invention is：

A kind of Socket casing, including drain pan and the cap being arranged at the drain pan upper opening, one end of the cap It is hinged by one end of bearing pin and the drain pan, the other end of the cap is connected by interface arrangment with the drain pan, described Gudgeon is provided with cap, the bearing pin is located in the perforation of the gudgeon, and bullet is formed on the periphery wall of the gudgeon Property boss, position corresponding with the gudgeon has arcwall face on the drain pan, stopper slot is formed on the arcwall face, institute State cap it is in an open position when, the elastic boss is engaged with the stopper slot.

In above-mentioned technical proposal, the interface arrangment includes the chuck taken shape on the drain pan and takes shape in the cap Elastic clamping hook on inner side, formed on the inside of the end of the elastic clamping hook suitable for the hook platform with the chuck clamping, and Form outwardly pressing boss on the outside of the elastic clamping hook, the cap cover on the downside of the rear pressing boss with it is described Have between drain pan corresponding site and be suitable to the space that finger fingertip stretches into.

In above-mentioned technical proposal, the interface arrangment includes spaced two elastic clamping hooks and spaced Two chuck, two elastic clamping hooks are correspondingly arranged with two chuck respectively.

The present invention has positive effect：(1) using the structure in the present invention, when cap is opened, it is flipped up cap Elastic boss is set to be slipped over from arcwall face, when cap is in the open position, the elastic boss is engaged pair with stopper slot Damping action is produced to cap, so as to prevent cap from being closed after opening under self gravitation effect, is maintained at cap Open position, so as to be advantageous to plug and socket grafting, there is good using effect, when needing to close cap, turn over downwards Transcapsidation lid makes elastic boss be skidded off from stopper slot so as to realize unblock.(2) using the structure in the present invention, covered in cap When, cap is closed and pressing cap makes the hook platform on the elastic clamping hook be engaged with the chuck on drain pan, is being opened During cap, finger fingertip is stretched into the space and pressing boss application is upwarded pressure, so that elastic clamping hook occurs Hook platform after being bent outwardly thereon releases with the chuck to be coordinated, and is at this moment flipped over cap and can be opened cap, operates It is convenient.

Embodiment

The concrete structure in the present invention is done with explanation with reference to Figure of description：

A kind of Socket casing, as shown in Figure 1 to Figure 3, including drain pan 1 and the shell that is arranged at the upper opening of drain pan 1 Lid 2, one end of the cap 2 are hinged by one end of bearing pin and the drain pan 1, and the other end of the cap 2 passes through clamping knot Structure is connected with the drain pan 1, and gudgeon 21 is provided with the cap 2, and the bearing pin 7 is located in the perforation 22 of the gudgeon 21 In, flexible boss 23 is molded on the periphery wall of the gudgeon 21, is had on the drain pan 1 with the 21 corresponding position of gudgeon There is arcwall face 24, form stopper slot 25 on the arcwall face 24, when the cap 2 is in an open position, the elasticity is convex Platform 23 is engaged with the stopper slot 25.Using said structure, when cap 2 is opened, being flipped up cap 2 makes elastic boss 23 Slipped over from arcwall face, when cap 2 is in the open position, the elastic boss 23 is engaged to cap with stopper slot 25 Damping action is produced, so as to prevent cap 2 from being closed after opening under self gravitation effect, cap 2 is maintained at opening Position, so as to be advantageous to plug and socket grafting, there is good using effect, when needing to close cap 2, downwardly turn over shell Lid 2 makes elastic boss 23 be skidded off from stopper slot 25 so as to realize unblock.

In the present embodiment, the interface arrangment includes the chuck 3 taken shape on the drain pan 1 and takes shape in the cap 2 Elastic clamping hook 4 on inner side, formed on the inside of the end of the elastic clamping hook 4 suitable for the hook platform 41 with the clamping of chuck 3, And outwardly pressing boss 5 is formed in the outside of elastic clamping hook 4, the cap 2 is covered under the rear pressing boss 5 Have between side and the corresponding site of the drain pan 1 and be suitable to the space 6 that finger fingertip stretches into, referring to shown in Fig. 3.Using the present embodiment In structure, when cap 2 covers, by cap 2 close and press cap 2 make hook platform on the elastic clamping hook 4 with drain pan Chuck be engaged, cap locking is reliable, and when opening cap 2, finger fingertip is stretched into the space and to by belling Platform, which applies, to upward pressure, so that hook platform thereon releases cooperation with the chuck after elastic clamping hook 4 is bent outwardly, this When cap 2 is flipped over and cap 2 can be opened, it is easy to operate.

Further, the interface arrangment in the present embodiment includes spaced two elastic clamping hooks 4 and interval Two chuck 3 set, two elastic clamping hooks 4 are correspondingly arranged with two chuck 3 respectively.

Obviously, the above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not pair The restriction of embodiments of the present invention.For those of ordinary skill in the field, may be used also on the basis of the above description To make other changes in different forms.There is no necessity and possibility to exhaust all the enbodiments.And these The obvious changes or variations that the connotation for belonging to of the invention is extended out still falls within protection scope of the present invention.
