CN200987157Y - Adjustment convenient signal receiving device - Google Patents

Abstract

The utility model discloses a signal receiving device convenient for adjustment, including a receiver, a base and an elastic tube, the shape of which can maintain characteristic. One end of the elastic tube is connected with the receiver, and the other end is connected with the base. The elastic tube is made of metal; however, the two ends of the elastic tube are respectively fixed on the receiver and the base through a nut. Combined with the structure, the change of signal receiving direction can be realized by pulling the receiver with hand, not only having easy and flexible usage, but also avoiding mechanical wear.

Description

A kind of signal receiving device easy to adjust

Technical field

The utility model relates to a kind of signal receiving device, relates in particular to a kind of receiver and base of comprising, is used for the signal receiving device of interactive teaching and learning equipment.

Background technology

Interactive teaching and learning equipment is learned spirit (ALA, advanced learning aid) as living, and is a kind of instrument of interaction, is suitable for using in occasions such as lecture hall or classrooms, is mainly used in field investigation, votes, inquires after, tests activities such as competition or joint operation.During use, ALA software is installed on computers, the output of signal receiver is connected with computer, and the user sends signal by reflector, is delivered to computer after being received by signal receiver, again by showing on screen after the ALA software processes.As shown in Figure 1, signal receiver under the prior art comprises signal receiver main body 1 and base 2, wherein, below signal receiver main body 1, be provided with a plastic cement spheroid 11, be provided with corresponding ball recess 21 in base 2 upper ends, signal receiver main body 1 is sleeved in the ball recess 21 by plastic cement spheroid 11, set correct position after, again a double-screw bolt 22 is located on the ball recess 21, thereby and withstands plastic cement spheroid 11 signal receiver main body 1 is fixed on the base 2.

This product in use, the receive direction of a signal receiver of every change just needs at first loose bolt 22, then by plastic cement spheroid 11 after ball recess 21 turns to correct position, again double-screw bolt 22 is screwed.This makes operation become very loaded down with trivial details, uses inconvenience, and frequent conversion can cause the mechanical wear between part.

The utility model content

Technical problem to be solved in the utility model provides a kind of signal receiving device easy to adjust, the direction of conditioning signal reception easily, and can avoid repeatedly regulating the mechanical wear of bringing.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is:

A kind of signal receiving device easy to adjust is provided, and it comprises receiver, has the elastic tube and the base of shape retention properties, and described elastic tube one end is connected with receiver, and the other end then is connected with base.

The material of described elastic tube is a metal; And the two ends of described elastic tube are to be separately fixed on receiver and the base by nut.

Adopt after such structure, change receiving side signal and get final product to only pulling receiver with hand, not only flexible and convenient to use, and avoided mechanical wear.

Embodiment

Signal receiving device a kind of easy to adjust shown in Fig. 2,3 and 4, it comprises receiver 3, has the elastic tube 5 and the base 4 of shape retention properties, and described elastic tube 5 one ends are connected with receiver 3, and the other end then is connected with base 4.

During concrete enforcement, the material of described elastic tube 5 is selected metal for use; And the two ends of described elastic tube 5 are to be separately fixed on receiver 3 and the base 4 by nut.Adopt after such structure, change receiving side signal to only pulling the optional position of receiver 3 with hand to needs, not only flexible and convenient to use shown in Fig. 5,6 or 7, and avoided mechanical wear.

Claims (3)

1, a kind of signal receiving device easy to adjust, it comprises receiver and base, it is characterized in that: this signal receiving device also comprises the elastic tube with shape retention properties, and described elastic tube one end is connected with receiver, and the other end then is connected with base.

2, signal receiving device easy to adjust according to claim 1 is characterized in that: the material of described elastic tube is a metal.

3, signal receiving device easy to adjust according to claim 1 and 2 is characterized in that: the two ends of described elastic tube are to be separately fixed on receiver and the base by nut.
