The beneficial effect of the utility model: the dismouting is simple swift, has improved the efficiency of work.
Description
Technical field
This utility model relates to a kind of joint, a kind of projector fixed mount joint.
Background technology
Projector fixing device is carrying projector a kind of fixing device being fixed on ceiling, is mainly used in classroom, academic hall and bigger meeting-place, and this device can reasonably utilize space, convenient teaching and work.
At present, according to requirements of one's work, traditional fixing device there is also some defects, such as: existing projector fixed mount is an entirety, when projector needs to disassemble maintenance, it is necessary to coordinates double ladder to dismount；Although existing fixed mount is divided into two parts, but the connected mode of these two parts is relatively complicated, mostly uses the connected mode of bolt, although which connects fastening, but dismounting easily brings damage, and dismounting inconvenience to equipment frequently.
In order to overcome drawbacks described above, on the basis of existing technology, make a formal request people and propose a kind of new technical scheme, it is provided that a kind of novel projector fixing device that can automatically dismount.
Summary of the invention
The purpose of this utility model is to provide a kind of projector fixed mount joint.
For achieving the above object, the technical solution of the utility model, including top connection, the interior lower end of described top connection is the groove of truncated cone-shaped, the sidewall of this groove is provided with the slideway of sector, the inner tip of the slideway of described sector is provided with the pin-and-hole running through top connection, and the inside left end of described pin-and-hole is provided with push rod, and described push rod passes through push rod spring and the internal links of pin-and-hole.
Also include lower contact, the upper end of described lower contact is provided with the projection matched with groove, the horizontal fixed block that sidewall in this projection is provided with and fan-shaped slideway matches, the inside of described projection is provided with the spring steady pin running through horizontal fixed block, and the left end of this spring steady pin and pin-and-hole match.
Owing to using technique scheme, the beneficial effects of the utility model are: using spring steady pin and push rod to match, dismounting is with easy for installation, time saving and energy saving, improves work efficiency；The setting of fan-shaped slideway can make steady pin be accurately positioned, it is not necessary to the most relatively position, quick compared with position；Horizontal fixed block and fan-shaped slideway match, and serve the effect positioned in the horizontal direction, it is to avoid projector is because the external force such as wind are in the vibrations of level side.
Accompanying drawing explanation
In conjunction with accompanying drawing, this utility model is described further.
Fig. 1 is profile of the present utility model.
Fig. 2 is the structural representation of top connection.
Fig. 3 is the structural representation of lower contact.
In figure: 1, top connection, 11, groove, 12, slideway, 13, pin-and-hole, 14, push rod, 15, push rod spring, 2, lower contact, 21, protruding, 22, horizontal fixed block, 23, spring steady pin.
Detailed description of the invention
As Figure 1-3, this utility model includes top connection 1, the groove that interior lower end is truncated cone-shaped 11 of described top connection 1, the sidewall of this groove 11 is provided with the slideway 12 of sector, the inner tip of the slideway 12 of described sector is provided with the pin-and-hole 13 running through top connection 1, the inside left end of described pin-and-hole 13 is provided with push rod 14, and described push rod 14 is by push rod spring 15 and the internal links of pin-and-hole 13.
Also include lower contact 2, the upper end of described lower contact 2 is provided with the projection 21 matched with groove 11, the horizontal fixed block 22 that sidewall in this projection 21 is provided with and fan-shaped slideway 12 matches, the described inside of protruding 21 is provided with the spring steady pin 23 running through horizontal fixed block 22, and the left end of this spring steady pin 23 and pin-and-hole 13 match.
Operation principle: during installation, by spring steady pin 23 coarse alignment sector slideway 12, and is pushed up lower contact 2, spring steady pin 23 shrinks to the right under the extruding of fan-shaped slideway 12, when top is shifted in lower contact 2 onto, spring steady pin 23 springs into pin-and-hole 13, lower contact 2 is fixed；During dismounting, only need to press push rod 14.
