Description

Technical Field

[0001] The utility model relates to the technical field of loudspeaker telephones, in particular to a loudspeaker telephone which is convenient for installation on a tape machine. Background Art

[0002] Belt conveyors for long-distance transportation need to be equipped with a comprehensive protection system. The existing technology mainly achieves functions such as locking, communication, early warning, and wire-pulling emergency stop along the belt conveyor by installing a main controller at the head of the belt conveyor and installing a combination loudspeaker telephone and a combination emergency stop locking switch along the line.

[0003] At present, loudspeakers are mainly fixed to the longitudinal beams of belt conveyors by bolts. Due to the harsh environment of mines, the bolts rust quickly, and the failure rate of combined loudspeakers gradually increases with the use time. Every time the combined loudspeaker is replaced, tools are needed to forcibly break the severely rusted fixing bolts, which is very troublesome. In addition, the belt conveyor will vibrate during operation, which can easily cause loosening. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4As shown, a loudspeaker telephone that is easy to install on a tape machine includes a loudspeaker telephone assembly 1, an operating panel 3 is provided on the front of the loudspeaker telephone assembly 1, a filter mechanism 4 is provided on the front of the operating panel 3, and a clamping mechanism 6 is installed on the rear side of the loudspeaker telephone assembly 1; in summary, the connecting plate 607 is restricted by the slide rail 601, so that the connecting plate 607 can only move up and down, and the bidirectional threaded rod 603 is rotated by turning the knob 604, so that the connecting plate 607 drives the clamping block 605 to move with each other, and the loudspeaker telephone assembly 1 is fixed to the horizontal tube of the tape machine by the clamping mechanism 6, and the installation and fixation is very simple and convenient. The two connecting plates 607 are pushed by the spring 608, so as to eliminate the thread gap between the connecting plate 607 and the bidirectional threaded rod 603, thereby reducing the influence of the tape machine vibration on the clamping mechanism 6 and preventing it from loosening.

[0021] The clamping mechanism 6 includes two left and right slide rails 601, two upper and lower fixed plates 602, a two-way threaded rod 603, a knob 604, a plurality of clamping blocks 605 and two upper and lower connecting plates 607. One side of the slide rail 601 is fixedly connected to the left and right sides of the rear of the loudspeaker telephone assembly 1. The left and right sides of the fixed plate 602 are fixedly connected to the upper and lower ends of the slide rail 601. The lower end of the two-way threaded rod 603 is rotatably connected to the middle of the lower fixed plate 602. The left and right sides of the connecting plate 607 are slidably connected to the upper and lower sides of the slide rail 601. One end of the plurality of clamping blocks 605 is fixedly connected to the far end of the connecting plate 607. On the side away from the slide rail 601, the middle part of the connecting plate 607 is threadedly connected to the upper and lower outer peripheries of the two-way threaded rod 603, and the middle part of the knob 604 is fixedly connected to the upper end of the two-way threaded rod 603. The connecting plate 607 is restricted by the slide rail 601 so that the connecting plate 607 can only move up and down. By turning the knob 604, the two-way threaded rod 603 is rotated, so that the connecting plate 607 drives the clamping block 605 to move with each other. The loudspeaker telephone assembly 1 is fixed to the horizontal pipe of the tape machine through the clamping mechanism 6, and the installation and fixation is very simple and convenient.

[0022] A rubber pad 606 is provided on the opposite side of the clamping block 605 to increase the friction between the clamping block 605 and the horizontal pipe on the belt conveyor to prevent it from moving.

[0023] A spring 608 is provided between the two connecting plates 607. The spring 608 is sleeved on the outer periphery of the bidirectional threaded rod 603. The two connecting plates 607 are pushed by the spring 608, thereby eliminating the thread gap between the connecting plates 607 and the bidirectional threaded rod 603, thereby reducing the influence of the belt conveyor vibration on the clamping mechanism 6 and preventing it from loosening.

[0024] A reflective strip 2 is provided on the front periphery of the operation panel 3 , and the reflective strip 2 enables workers to quickly find the exact position of the loudspeaker telephone assembly 1 in a dim environment.

[0025] The filtering mechanism 4 includes a mounting groove 401, a magnetic sheet 402 and a filter 403. The mounting groove 401 is opened at the lower part of the operation panel 3. The mounting groove 401 is set on the periphery of the sound hole. The periphery of the filter 403 is fixedly connected to the inside of the magnetic sheet 402. The magnetic sheet 402 is magnetically attracted to the inside of the mounting groove 401. The filter 403 can be easily removed from the mounting groove 401 through magnetic attraction, which facilitates cleaning or replacement of the filter 403, prevents dust from clogging the filter 403, and ensures that sound can be transmitted.

[0026] The four corners of the loudspeaker telephone assembly 1 are provided with mounting holes 5. When necessary, the clamping mechanism 6 can be removed from the loudspeaker telephone assembly 1 by removing the screws on the slide rail 601, and then the loudspeaker telephone assembly 1 can be fixed on the tape machine through the mounting holes 5. There are various installation methods.

[0027] Working principle:

[0028] The connecting plate 607 is restricted by the slide rail 601 so that the connecting plate 607 can only move up and down. By turning the knob 604, the bidirectional threaded rod 603 is rotated, so that the connecting plate 607 drives the clamping block 605 to move with each other. The loudspeaker telephone assembly 1 is fixed to the horizontal tube of the tape machine through the clamping mechanism 6. The installation and fixation are very simple and convenient. The two connecting plates 607 are pushed by the spring 608, thereby eliminating the thread gap between the connecting plate 607 and the bidirectional threaded rod 603, thereby reducing the influence of the tape machine vibration on the clamping mechanism 6 and preventing it from loosening.
