Abstract

The utility model relates to a structure application technique among the machinery trade especially relates to the lid structure that is applied to the automatic accurate of electrical accessories and resets. The double-hinge type double-hinge structure comprises a bottom box and an upper cover which are mutually buckled, wherein the fixed connecting end of the bottom box and the upper cover is a double-hinge structure with a reset spring. When the waterproof box is opened, the bottom box connecting shaft is firstly opened and closed by 90 degrees under the cooperation of the reset spring, the upper cover connecting shaft is continuously rotated and opened under the cooperation of the reset spring until 180 degrees, and the bottom box and the upper cover are opened by 180 degrees under the driving of the bottom box connecting shaft and the upper cover connecting shaft. When the external force is removed, the bottom box and the upper cover automatically reset under the resilience force of the reset spring. The connecting end of the box cover is not easily influenced by the opening and closing angle of the box cover, and has firm structure, long service life and convenient opening and closing.

Description

Automatic lid structure that accurate resets

Technical Field

The utility model relates to a structure application technique among the machinery trade especially relates to the lid structure that is applied to the automatic accurate of electrical accessories and resets.

Background

The box cover and the box body of the existing electric waterproof box product are connected by a common single-shaft structure. The opening angle of the box cover is far less than 180 degrees. This design has the disadvantage that the user does not know where the maximum opening position is when opening the lid, which can easily cause excessive opening and damage to the product. The double hinge structure has other applications, but is not applied to waterproof box products. Even more without an accurate reset structure. The waterproof case cannot be accurately reset.

SUMMERY OF THE UTILITY MODEL

To the technical problem, the utility model provides a technical problem provide an automatic lid structure that resets of accuracy.

In order to solve the technical problems, the technical scheme of the invention is as follows: the utility model provides an automatic lid structure that accurate reseed, includes end box and the upper cover of mutual lock, the fixed connection end of end box and upper cover be the double-hinge structure of taking reset spring.

Further: in the automatic and accurate reset box cover structure, the double-hinge structure comprises a bottom box connecting shaft with two ends embedded in the bottom box connecting end and an upper cover connecting shaft with two ends embedded in the upper cover connecting end, and the main parts of the bottom box connecting shaft and the upper cover connecting shaft are fixed on the connecting frame in parallel. And the bottom box connecting shaft and the upper cover connecting shaft are provided with return springs with opposite mounting directions. The specifications, the models and the materials of the reset springs on the bottom box connecting shaft and the upper cover connecting shaft are the same, and the elasticity of the two reset springs is ensured to be the same.

Compared with the prior art, the utility model discloses an automatic accurate lid structure that resets, end box and upper cover including mutual lock, the fixed connection end of end box and upper cover be the double-hinge structure of taking reset spring. When the waterproof box is opened, the bottom box connecting shaft is firstly opened and closed by 90 degrees under the cooperation of the reset spring, the upper cover connecting shaft is continuously rotated and opened under the cooperation of the reset spring until 180 degrees, and the bottom box and the upper cover are opened by 180 degrees under the driving of the bottom box connecting shaft and the upper cover connecting shaft. When the external force is removed, the bottom box and the upper cover automatically reset under the resilience force of the reset spring. Because the size and the type of the two reset springs are the same, the elasticity is also the same, and the automatic resetting precision of the bottom box and the upper cover is very high. And the connecting end of the box cover is not easily influenced by the opening and closing angle of the box cover, and has firm structure, long service life and convenient opening and closing.

Detailed Description

To facilitate understanding for those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and examples.

Referring to FIGS. 1-3: the utility model provides an automatic lid structure that accurate reseed, includes end box 1 and upper cover 2 of mutual lock, the fixed connection end of end box and upper cover be the double-hinge structure 3 who takes reset spring. The double-hinge structure 3 comprises a bottom box connecting shaft 4 with two ends embedded in the bottom box connecting end and an upper cover connecting shaft 5 with two ends embedded in the upper cover connecting end, and the main parts of the bottom box connecting shaft 4 and the upper cover connecting shaft 5 are fixed on a connecting frame 6 in parallel. And the bottom box connecting shaft 4 and the upper cover connecting shaft 5 are provided with return springs 7 with opposite installation directions. The return spring on the bottom box connecting shaft and the upper cover connecting shaft is the same in specification, model and material.

When the waterproof box is opened, the bottom box connecting shaft 4 is firstly opened and closed and rotated by 90 degrees under the matching of the reset spring 7, the upper cover connecting shaft 5 is continuously rotated and opened under the matching of the reset spring 7 until 180 degrees, and the bottom box 1 and the upper cover 2 are driven by the bottom box connecting shaft 4 and the upper cover connecting shaft 5 to be opened by 180 degrees. When the external force is removed, the bottom box 1 and the upper cover 2 automatically reset under the resilience force of the reset spring 7. Because the size and the type material of the two reset springs 7 are the same, the elasticity thereof is also the same, and the automatic resetting precision of the bottom box 1 and the upper cover 2 is very high.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not limitations to the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
