Abstract

The utility model discloses a square ruler with lighting function, which comprises a ruler body and a ruler seat vertically connected at one end of the ruler body. Scales are marked on the ruler body, and a liquid horizontal pipe is arranged on the ruler seat. A lighting assembly arranged at one side of the liquid horizontal pipe on the ruler seat comprises a lamp, a power supply, a spring and a knob switch. The lamp can be turned on by the knob switch, so as to supply power for observing the liquid horizontal pipe in an environment with insufficient light; the operation is extremely convenient; meanwhile, the lighting assembly only consists of a few components including the lamp, the power supply, the spring and the knob switch, so that the structure is quite simple.

Description

A kind of try square with illumination functions

Technical field:

The utility model relates to a kind of survey instrument, particularly a kind of try square with illumination functions.

Background technology:

Try square of the prior art, comprise chi body and the rod support that is vertically connected on chi body one end, the chi body is marked with scale, the fluid level pipe is installed on the rod support, rod support is mainly used in and measures length and line usefulness on this try square, rod support is mainly used in the levelness of measurement plane and uses, very convenient, but, this try square can only use in well-lighted environment, as if the levelness of measurement plane in the insufficient environment of light, just is difficult to see clearly the demonstration situation of fluid level pipe, and then can not obtain measured value accurately, use very inconvenient.

The utility model content:

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of try square of band illumination functions easy to use, simple in structure is provided.

A kind of try square that provides according to the utility model with illumination functions, comprise chi body and the rod support that is vertically connected on chi body one end, the chi body is marked with scale, the fluid level pipe is installed on the rod support, in fluid level pipe one side one light fixture is installed also on the described rod support, this light fixture comprises electric light, power supply, spring and rotary switch, passes through rotary switch, can open electric light, provide light source under the insufficient environment of light, observing the fluid level pipe.

The utility model also has following attached technical characterictic:

Its longitudinal direction of described rod support upper edge has a horizontally disposed blind hole, described fluid level pipe, electric light, power supply, spring and rotary switch are installed in this blind hole successively from inside to outside, also have a through hole in fluid level pipe corresponding position on the rod support, this through hole is communicated with blind hole simultaneously.

Have internal thread on the inwall of described blind hole outer end, described rotary switch is provided with the external thread with this screw-internal thread fit, and described spring is installed between power supply and the rotary switch.

Described rod support is made by conductive material, and when described electric light was opened, electric light, power supply, rotary switch and rod support formed a power circuit.

A kind of try square with illumination functions that provides according to the utility model with respect to the advantage of prior art is:

In the utility model, in fluid level pipe one side one light fixture is installed also on the rod support, when under the insufficient environment of light, using, can open this light fixture, the electric light on this light fixture can provide light source for observing the fluid level pipe, and is very convenient, simultaneously, this light fixture is made up of electric light, power supply, spring and rotary switch, and its member is fewer, and structure is very simple.

Description of drawings:

Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structure for amplifying synoptic diagram of I among Fig. 1.

Embodiment:

With reference to Fig. 1, Fig. 2, a kind of try square that provides according to the utility model with illumination functions, comprise chi body 1 and the rod support 2 that is vertically connected on chi body 1 one ends, chi body 1 is marked with scale, its longitudinal direction of rod support 2 upper edges has a horizontally disposed blind hole 21, fluid level pipe 3, electric light 41, power supply 42, spring 43 and rotary switch 44 are installed in this blind hole 21 successively from inside to outside, fluid level pipe 3 is a body, its inner floating has a bubble, when bubble mediates, represent this body to be horizontal, also have a through hole 22 in fluid level pipe 3 corresponding positions on the rod support 2, this through hole 22 is communicated with blind hole 21 simultaneously, is used to observe the position of the bubble in the fluid level pipe 3, and then determined level value, rod support 2 is made by conductive material, when electric light 41 is opened, and electric light 41, power supply 42, rotary switch 44 and rod support 2 form a power circuit, when using under the insufficient environment of light, this electric light 41 can provide light source for observing fluid level pipe 3.

Have internal thread 28 on the inwall of blind hole 21 outer ends, rotary switch 44 is provided with the external thread 29 that cooperates with this internal thread 28, spring 43 is installed between power supply 42 and the rotary switch 44, rotary switch 44 turns clockwise, move in the rotary switch 44, compression spring 43 is also replaced with power supply 42, at this moment, electric light 41, power supply 42, rotary switch 44 and rod support 2 form a power circuit, and electric light 41 energisings are rotated counterclockwise rotary switch 44, rotary switch 44 outer moving, and break away from power supply 42 and to replace, at this moment, electric light 41, power supply 42, the loop that rotary switch 44 and rod support 2 form disconnects, electric light 42 is closed, simultaneously, compression spring 43 is still replaced power supply 42, stops power supply 42 to move freely in blind hole 21.

The foregoing description is only for the usefulness that the utility model is described; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
