Description

Telescopic bird feeder

Technical field

The utility model relates to a kind of bird feeder, particularly a kind of bird feeder with stretching structure.

Background technology

As shown in Figure 1, existing bird feeder generally is made of hook 10, fixing 20, top cover 30 and chassis 40, and top cover 30 is connected by non-telescoping support bar 50 with chassis 40.Because the support bar 50 of bird feeder is non-telescoping, so for the ease of feeding bird, support bar 50 must have enough length, this makes that the volume of bird feeder is bigger all the time, not only is inconvenient to pack and transport, and increases the cost of packing and transportation; And when bird feeder does not use when need deposit, the storage area that bird feeder takies is bigger, also is inconvenient to collect.

The inventor researchs and develops out a kind of telescopic bird feeder at the problems referred to above, and the stretching structure by bird feeder can be with the smaller volume of bird feeder, and is instant packed, transport and deposit, and this case produces thus.

The utility model content

The purpose of this utility model is to provide a kind of telescopic bird feeder, and bird feeder can be stretched or shrink according to need, and is with the smaller volume of bird feeder, instant packed, transport and deposit when not using.

To achieve these goals, the technical solution of the utility model is as follows:

Telescopic bird feeder comprises hook, top cover and chassis, and hook is installed in the top of top cover, and the chassis is positioned at the below of top cover, it is characterized in that: top cover is connected by an expansion link with the chassis.

Above-mentioned expansion link is made up of pipe in an outer tube and, the diameter of interior pipe is less than the diameter of outer tube, interior pipe is nested in the outer tube, the end that interior pipe stretches into outer tube has dop, outer tube forms reducing for the end that interior pipe stretches into, greater than the diameter of reducing, fixedly connected with top cover with the chassis respectively by the other end of interior pipe and outer tube less than the diameter of outer tube for the diameter of dop.

The other end of above-mentioned outer tube forms internal thread, the top cover top increases a fixedly head, hook is installed in the top of fixing head, the below of fixing head forms threaded post, have through hole on the top cover, the threaded post of fixing head pass top cover through hole and with the screw-internal thread fit of outer tube, top cover then is fixed between the other end of fixing head and outer tube.

The other end of pipe forms external screw thread in above-mentioned, forms screwed hole on the chassis, and the chassis cooperates the other end that is fixed on interior pipe with the external screw thread of interior pipe by its screwed hole.

The external diameter of above-mentioned top cover is greater than the external diameter on chassis.

Also increase a chain or rope between above-mentioned hook and the fixture, the two ends of chain or rope are separately fixed on hook and the fixing head.

Above-mentioned fixing piece is fish or other moulding.

After adopting such scheme, the utility model is because of connecting by expansion link between top cover and the chassis, during use, bird feeder is hung in the tree by hook or on other supporters, come because of action of gravity drives the expansion link full extension in the chassis, leave enough distances between chassis and the top cover, can make things convenient for small bird to carry out feeding or hello water; When transportation or when depositing, take off bird feeder, top cover drives expansion link and shrinks fully because of action of gravity, and top cover and chassis are close to and snap together, and volume reduces greatly, and is instant packed, transport or deposit.

Below in conjunction with the drawings and specific embodiments the utility model is described further.

Embodiment

To shown in Figure 6, is preferred embodiment of the present utility model as Fig. 2.

Telescopic bird feeder comprises hook 1, top cover 3 and chassis 4.

Hook 1 is installed in the top of top cover 3.

Chassis 4 is positioned at the below of top cover 3.Fall into chassis 4 contaminated foods or water for fear of dust, this embodiment designs the external diameter of top cover 3 greater than the external diameter on chassis 4.

Improvement of the present utility model is that top cover 3 is connected by an expansion link 5 with chassis 4.

Expansion link 5 specifically can 52 be made of (also can be the structure that connects together of multitube more, or other telescopic structure) pipe in an outer tube 51 and.The diameter of interior pipe 52 is less than the diameter of outer tube 51, and interior pipe 52 is nested in the outer tube 51.In pipe 52 ends (this embodiment is the upper end) that stretch into outer tube 51 have dop 53, outer tube 51 forms reducing 54 for the end (this embodiment is the lower end) that interior pipe 52 stretches into, the diameter of dop 53 less than the diameter of outer tube 51 greater than the diameter of reducing 54.

The other end (this embodiment is the lower end) of pipe 52 is fixedlyed connected with chassis 4 in the expansion link 5, its connected mode can be that buckle connects, also can be to be threaded, present embodiment is for to be threaded: the lower end at interior pipe 52 forms external screw thread, form screwed hole on chassis 4, chassis 4 cooperates the lower end that is fixed on interior pipe 52 with the external screw thread of interior pipe 52 by its screwed hole.

The other end of expansion link 5 outer tubes 51 (this embodiment is the upper end) is fixedlyed connected with top cover 3, its connected mode can be that buckle connects, also can be to be threaded, present embodiment is for to be threaded: the upper end at outer tube 51 forms internal thread, above top cover 3, increase by one fixing 2, hook 1 is installed in fixing 2 top, fixing 2 below forms threaded post, have through hole on the top cover 3, fixing 2 threaded post pass top cover 3 through hole and with the screw-internal thread fit of outer tube 51, top cover 3 is fixed between the upper end of fixing 2 and outer tube 51.Certainly, also outer tube 51 can be connected with chassis 4, interior pipe 52 is connected with top cover 3, and its purpose, means and effect embodiment therewith are identical, belong to equivalent technologies.

When the utility model uses, bird feeder is hung in the tree by hook 1 or on other supporters, chassis 3 is because of action of gravity, pipe 52 slides into outer tube 51 bottoms in driving in outer tube 51, the expansion link full extension is left, since the diameter of dop 53 less than the diameter of outer tube 51 greater than the diameter of reducing 54 described later, feasible interior pipe 52 can be free to slide in outer tube 51 and can not come off from outer tube 51, bird feeder is opened naturally and is conveniently carried out feeding, for make connect between hook 1 and the top cover 3 more firm, rotate more flexible, between hook 1 and the fixture 2 chain or rope can be set, present embodiment is a chain 6, and the two ends of chain 6 are separately fixed on hook 1 and fixing 2, when bird feeder is suspended on when aerial, can alleviate the wind-force effect that bird feeder is subjected to, the minimizing birdseed pours out from the chassis or water therefrom overflows, waste birdseed or water.In addition, this fixture 2 can be fish or other moulding, both can increase the decorative effect of bird feeder, can attract bird to come to take food again.

When transportation or when depositing, take off bird feeder, top cover 3 drives outer tube 51 and manage 51 bottoms in personal the sliding into outside interior pipe 52 because of action of gravity, bird feeder is taken in naturally, top cover 3 and chassis 4 are close to and snap together, and volume reduces, and be instant packed, transport or deposit, again, because of the maximum gauge of top cover 3 maximum gauge greater than chassis 4, top cover 3 can hide chassis 4 fully, prevents that birdseeds in the chassis 4 from rotting or water is polluted.

The above is preferred embodiment of the present utility model only, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
