Background

As a small household appliance product with mature technology, a desk lamp is well known and used by consumers. The base of desk lamp generally divide into upper cover and lower cover, need place parts such as balancing weight, circuit board between the upper and lower cover, and the upper cover and the lower cover of desk lamp use screw nut's cooperation usually, and screw nut's fastening is closed effectual, and stability is high, is difficult to not hard up. However, a plurality of pairs of screw nuts are needed to be matched between the upper cover and the lower cover of the desk lamp base, generally, the number of the screw nuts is not less than 4, and due to the fact that the screw nuts are small in size and difficult to position before screwing, fastening must be performed by using an automatic instrument with high precision or skilled workers, a large amount of funds or manpower is needed to be consumed to handle the problem of screwing of the screw nuts in the actual production process, and production efficiency of the desk lamp is low directly. Therefore, the base which is good in closing effect between the upper cover and the lower cover, simple in structure, convenient in installation process, high in production efficiency, free of large labor consumption and low cost in installation is designed, and the base has a very good social significance.

Disclosure of Invention

The invention aims to overcome at least one defect of the prior art, provides the base which has a simple product structure, a convenient and quick installation process and a good closing effect, and is used for solving the problem of low efficiency caused by the fact that the upper cover and the lower cover of the traditional base are fastened by screws and nuts.

The invention also aims to use the base with the upper cover and the lower cover which are integrally formed, and the traditional screw and nut matching is not needed, so that the number of accessories is reduced, the product cost is saved, and the problem that the desk lamp is damaged due to rusting of the screw and nut is avoided.

The technical scheme adopted by the invention is as follows:

the base comprises an upper cover and a lower cover, wherein the upper cover is provided with a plurality of clamping holes, the lower cover is provided with a plurality of clamping hooks, the clamping holes are matched with the clamping hooks, and through holes are formed beside the clamping hooks. The card hole and the trip are respectively the upper cover of base and a part of lower cover, and during production, the card hole and upper cover integrated into one piece, trip and lower cover integrated into one piece need not extra process and add. When the cover is closed, the upper cover and the lower cover are aligned, a certain force is applied, the clamping hook is matched with the clamping hole, the clamping hook part is sleeved into the clamping hole, and the upper cover and the lower cover are fastened at the same time.

The trip includes vertical connecting plate and locates the flange on connecting plate top. The connecting plate and the flange are integrally formed, no crack exists between the connecting plate and the flange, the strength is high, the flange of the clamping hook is directly contacted with the clamping hole, and the flange is clamped into the clamping hole after being stressed.

The flange is located directly above the through hole. The upper cover and the lower cover are closed without using screws and nuts, and when the upper cover and the lower cover are closed and need to be maintained in case of a fault of the table lamp, an opening and closing method needs to be designed.

And reinforcing ribs are arranged on the back of the clamping hooks. Because of the restriction of desk lamp base inner space, the connecting plate can not be too thick, and the power of going up the lower cover closure in the twinkling of an eye is great, and the longitudinal pressure that the connecting plate bore is big, has the risk of rupture, and the strengthening rib is perpendicular with the connecting plate, and the setting up of strengthening rib can strengthen the rigidity of connecting plate on vertical, makes the difficult rupture of connecting plate.

The clamping hooks are uniformly arranged on the lower cover, and the direction of the flanges on the adjacent clamping hooks is different. If the clamping hook is only arranged at one end of the lower cover, the closeness of the base is poor, the one end without the clamping hook is poor in closure, the clamping hook is uniformly arranged on the lower cover, the closure effect of the base is improved, meanwhile, the force applied to the upper cover and the lower cover in all directions is uniform, and the clamping hook clamping hole is not easy to loosen. If the flanges of the hooks face the same direction, even if the lower cover is uniformly provided with a plurality of hooks, the upper cover and the lower cover of the base are easy to separate when the lower cover and the flanges of the hooks face the same direction.

Further, the flanges of the two opposite clamping hooks face oppositely. The flanges face different directions, so that the connection of each group of clamping hooks and the clamping holes has an interlocking effect, and the upper cover and the lower cover of the bottom plate are not easy to be opened due to the action of external force.

The number of the clamping holes is not less than 4. The hole-clamping hooks are evenly distributed on the upper cover and the lower cover of the base in pairs, and at least one pair of four corners is arranged. The more preferred scheme is that, besides a pair of clamping hole clamping hooks is respectively arranged at four corners of the base, two pairs of clamping holes are also arranged at the middle part of the base, so that the closing effect of the base is better improved.

The lower cover is provided with a plurality of positioning columns, a plurality of positioning column plug-in units are distributed on the upper cover, and the positioning columns are matched with the positioning column plug-in units; and/or a plurality of circuit board supporting columns are arranged on the lower cover; and/or a plurality of balancing weight supporting columns are arranged on the lower cover. The positioning column is used for limiting the positions of the parts in the upper cover and the lower cover, so that the parts cannot shift when the base moves. The circuit board support column and the balancing weight support column are respectively used for limiting the positions of a circuit board and a balancing weight arranged in the base, and the stability of the base is improved.

The upper cover is provided with circuit boards with different height levels, and the circuit board support columns and the positioning columns are distributed in a height mode on the lower cover. The circuit board quantity and the shape of upper cover are decided according to the function that the desk lamp will realize, under the circumstances that the circuit board changes, can design the high distribution of different circuit board support columns and reference column according to the actual condition of placing of circuit board, and the cooperation is inseparable between the messenger upper and lower cover, and when the base removed, the circuit board position did not take place to remove, is favorable to improving the quality of base stability and desk lamp.
