Abstract
The utility model relates to a laser heavy hammer. The conventional hammer needs to be adjusted repeatedly before performing measurement, thus being low in work efficiency. The laser hammer provided by the utility model comprises a hammer body and a string, wherein a laser transmitting device is arranged in the hammer body, the laser transmitting device comprises an infrared laser, a battery and an elastic switch, the elastic switch comprises a guide post, two static contacts, two dynamic contacts and a spring, a central hole is arranged on the hammer body, the guide post penetrates in the central hole, the spring is sleeved on the guide post, the outer diameter of the spring is greater than the inner diameter of the central hole, the lower end of the guide post is provided with a spring tray, the two dynamic contacts are arranged on the two sides of the spring tray, the two static contacts are arranged above the dynamic contacts, the weights of the heavy hammer body and the laser transmitting device are large enough to overcome the elastic force of the spring and further enable the static contacts to contact with the dynamic contacts. The laser heavy hammer provided by the utility model is convenient to switch on/off, time-saving and quick to use, greatly improves the work efficiency of measurement personnel and is widely applied to the environment in need of the heavy hammer.
Description
Technical field
The utility model relates to a kind of weight, particularly a kind of laser weight.
Background technology
As shown in Figure 1, existing weight comprises weight body 1 and cord 2, and the weight body is turbination, and the weight point 11 of an activity is arranged at its bottom.Carry out in the centring under point process at transit, need adjust weight point 11 exposed lengths repeatedly, and want constantly to observe the offset of weight, wasted the time of survey crew, reduced the work efficiency of survey crew from both direction.
The utility model content
The technical matters that the utility model will solve is the above-mentioned defective that how to overcome prior art, and a kind of laser weight is provided.
For solving the problems of the technologies described above, this laser weight comprises weight body and cord, and cord is connected on the weight body; Be provided with laser beam emitting device in the weight body, laser beam emitting device comprises infrared laser, battery and switch, and the three is connected into controlled Laser emission loop; Laser and cord all are positioned on the axis of weight body, it is characterized in that: said switch is the elastic force switch, and this elastic force switch comprises guidepost, two stationary contacts, two moving contacts and spring; Have a center pit on the said weight body, guidepost just is located in this center pit, and said spring just is enclosed within on this guidepost; The spring external diameter is greater than the center pit internal diameter, and cord just is connected the guidepost upper end, and the guidepost lower end is provided with spring tray; Two moving contacts are arranged on the spring tray both sides; Two stationary contacts are arranged on the moving contact top, and the weight of weight body and laser beam emitting device is enough to overcome the elastic force of spring, and stationary contact is contacted with moving contact.So design, when weight suspended in midair naturally, because action of gravity, length of spring compressed made the elastic force switch closure, and infrared laser is opened naturally; After packing up weight, spring restores to the original state, and infrared laser breaks off immediately, and switch is convenient, centering saves time, and has improved the work efficiency of survey crew.
As optimization, said weight body lower end is tapered, and the lightening hole of said infrared laser is positioned at center, said weight body lower end.So design, infrared laser beam is vertically sagging, need not adjust repeatedly, uses more convenient.
The utility model laser weight, switch is convenient, uses to save time fast, has improved the work efficiency of survey crew greatly, needs to use in the environment of weight adaptable across mine, down-hole, geologic prospecting, building etc.
Description of drawings
Below in conjunction with accompanying drawing this laser weight is described further:
Fig. 1 is the axial part section structural representation of existing weight;
Fig. 2 is the axial part section structural representation of this laser weight.
Among the figure: 1 for weight body, 11 attach most importance to toe, 2 for cord, 21 for cotton rope hook, 3 laser beam emitting devices, 4 for lightening hole, 31 for infrared laser, 32 for battery, 33 for the elastic force switch, 331 for guidepost, 332 for stationary contact, 333 for moving contact, 334 be that spring, 335 is a spring tray.
Embodiment
Embodiment one: as shown in Figure 2, this laser weight comprises weight body 1 and cord 2, and cord 2 is connected on the weight body 1; Be provided with laser beam emitting device 3 in the weight body, laser beam emitting device 3 comprises infrared laser 31, battery 32 and switch, and the three is connected into controlled Laser emission loop; Laser and cord 2 all are positioned on the axis of weight body 1, it is characterized in that: said switch is an elastic force switch 33, and this elastic force switch comprises guidepost 331, two stationary contacts 332, two moving contacts 333 and springs 334; Have a center pit on the said weight body 1; Guidepost 331 just is located in this center pit, and said spring 334 just is enclosed within on this guidepost 331, and spring 334 external diameters are greater than the center pit internal diameter; Cord 2 just is connected guidepost 331 upper ends; Guidepost 331 lower ends are provided with 335, two moving contacts 333 of spring tray and are arranged on spring tray 335 both sides, and two stationary contacts 332 are arranged on moving contact 333 tops; The weight of weight body 1 and laser beam emitting device 3 is enough to overcome the elastic force of spring 334, and stationary contact 332 is contacted with moving contact 333.
Said weight body 1 lower end is tapered, and the lightening hole 4 of said infrared laser 31 is positioned at center, said weight body 1 lower end.
Claims (2)
1. a laser weight comprises weight body and cord, and cord is connected on the weight body; Be provided with laser beam emitting device in the weight body, laser beam emitting device comprises infrared laser, battery and switch, and the three is connected into controlled Laser emission loop; Laser and cord all are positioned on the central axis of weight body, it is characterized in that: said switch is the elastic force switch, and this elastic force switch comprises guidepost, two stationary contacts, two moving contacts and spring; Have a center pit on the said weight body, guidepost just is located in this center pit, and said spring just is enclosed within on this guidepost; The spring external diameter is greater than the center pit internal diameter, and cord just is connected the guidepost upper end, and the guidepost lower end is provided with spring tray; Two moving contacts are arranged on the spring tray both sides; Two stationary contacts are arranged on the moving contact top, and the weight of weight body and laser beam emitting device is enough to overcome the elastic force of spring, and stationary contact is contacted with moving contact.
