Description

desk lamp

technical field

The utility model relates to the technical field of lamps, in particular to a table lamp.

Background technique

The current desk lamps are more and more diverse to meet the increasing different needs, but the structure of the desk lamp with double lamp caps is not common. The applicant has previously disclosed some desk lamps with double lamp caps. Although they are convenient to use, they cannot be turned off at regular intervals.

An idea is provided in the prior art, which is to use a structure such as a delay circuit to control the timing shutdown of a lamp head. Although timing shutdown can be realized, it involves semiconductor technology, the structure is relatively complicated, and it cannot be directly used on a desk lamp with two lamp caps. .

Utility model content

The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a table lamp that can be turned off at regular intervals and has a relatively simple structure.

In order to solve the above-mentioned technical problems, the utility model proposes a table lamp, which includes a lamp cap, a base body and lamp caps arranged on the left and right sides of the base body, and each lamp cap is electrically connected with a timing closing structure; the timing closing structure includes an hourglass, a set The elastic sheets at both ends of the hourglass, the seat body is provided with a stepped hole consisting of two holes with a large top and a small bottom. From top to bottom are the first hole and the second hole, the first hole is used to place one end of the hourglass, the second The two holes are movable socketed with a support plate, and a push switch is arranged under the support plate, and the upper end surface of the button part of the push switch is attached to the lower surface of the support plate; for each lamp cap, the lamp cap, the push switch, and the power supply electrical connection.

After adopting the above-mentioned structure, compared with the prior art, the utility model has the following advantages: each lamp cap is provided with a timing closing structure, and the timing closing structure utilizes the characteristic that the hourglass can roughly time the time to realize the purpose of timing, and the two ends of the hourglass are closed It is an elastic sheet located at both ends of the hourglass. Therefore, when the sand in the hourglass accumulates to a certain extent, the accumulated sand will overcome the support force of the elastic sheet and the support force of the button part to make the elastic sheet protrude downward, thereby turning the button part Press to disconnect the power supply circuit of the lamp head. The push switch is a switch that the button part is pressed to disconnect, and the button part is reset to connect. As long as the hourglass is turned upside down, it can be turned off at a fixed time. It is convenient to use. Based on the above, the utility model It does not need to use semiconductor technology, can be turned off at regular intervals, and has a relatively simple structure.

As an improvement, the slider body includes a rectangular bottom and a hollow trapezoidal body, the small end of the trapezoidal body is the upper end of the seat body, and the large end of the trapezoidal body is connected to the middle of the rectangular bottom; There is a hollow pole, two hollow poles are arranged in an inverted splayed shape, and the upper end of each hollow pole is connected to a lamp holder; the part of the rectangular bottom located on the left and right sides of the trapezoid body is provided with the above-mentioned stepped holes, each An hourglass is provided in the step hole, so that the operation of the hourglass is convenient and the lighting effect of the lamp head is good, so it is more ergonomically designed.

As an improvement, a guide rod is provided between the support plate and the bottom of the second hole, one end of the guide rod is fixedly connected to the support plate, a guide hole is provided at the bottom of the second hole, and the guide rod and the guide hole are movably socketed, which is more conducive to Ensure that the support plate only moves up and down in a straight line, and the support plate can be made thinner.

As an improvement, the guide rod is sleeved with a spring, the upper end of the spring is in contact with the lower surface of the support plate, and the lower end of the spring is in contact with the bottom of the second hole, so that the supporting force can be provided by the spring, so that the push-type switch can use the button part with less elastic force The switch can improve the sensitivity of the push switch, and at the same time, the spring can also be strengthened so that the support plate can accumulate more sand, which means that the timing can be longer.
