Abstract
The utility model discloses a book end which can automatically clamp books. The book end comprises a fixing part and a moving part (7) which are mutually separated, wherein the fixing part comprises an iron core (1), a coil (2), a sliding rail (6), a movable contact (3), a switch (4) and a power supply (5), wherein the coil (2) is wound around the iron core; the sliding rail (6) is fixed on the iron core; one end of the movable contact (3) is contacted with the coil, the other end of the movable contact (3) is fixed on the sliding rail, and the movable contact (3) can slide along the sliding rail; the switch (4) is connected with the coil; and the iron core (1) and the moving part (7) are soft iron parts or silicon steel parts. The book end of the utility model can automatically clamp books, prevent erect books from dumping, improve the efficiency of library management, and avoid the unnecessary damages on books.
Description
Technical field
The utility model relates to the book end technical field of structures of books vertical in a kind of fixedly bookshelf or the bookcase, is applicable to family, school, enterprise and books and reference materials store and manage unit.
Background technology
At present, the book end of selling on the market is formed by a pair of iron plate of falling the T-shape.During use, books are stood in the middle of two iron plates of falling the T-shape, reach with books uprightly place, the attractive in appearance and effect of saving the space.But because these two iron plates of falling the T-shape just mechanically are clipped in the two ends of books; external force does not support; more or when having the people to extract books out when folded books from the centre; make inverted T shape iron plate leave the origin-location through regular meeting; books are toppled over easily; not only not attractive in appearance, and easily books are lost.Especially sell, serve at public books and reference materials and the management place, often this thing happens as places such as library, reading rooms, needs the keeper often manually it to be held up, and increased keeper's workload, also is unfavorable for the management of books.
Summary of the invention
The purpose of this utility model is to solve the deficiency that above-mentioned prior art exists and a kind of book end that can clamp books automatically is provided, and prevents to erect toppling over of books, improving taking care of books efficient, and avoids books to suffer unnecessary damage.
The purpose of this utility model is achieved by the following technical solution.
Can clamp the book end of books automatically, comprise the fixture and the movable part that are separated from each other, fixture comprises iron core, around the coil of iron core outside, the other end is fixed on the slide rail and can be along movable contact, the switch that is connected with coil and the power supply of slide rail slip with the coil contact to be fixed on slide rail on the iron core, an end; Iron core and movable part are soft iron or silicon steel spare.
Movable part described in the utility model is structure of falling the T-shape or slab construction.Described power supply is dry cell or AC power.
When switch is placed open mode, coil produces magnetic field, and iron core is magnetized, and forms an electromagnet, movable part is produced an attraction, thereby books are clamped automatically.When need take out books from the centre, only need switch is placed closed condition, coil magnetic field is disappeared, iron core also loses magnetism, and the attraction of movable part is disappeared thereupon, just can like a cork books be taken out from the centre.Can once more switch be placed open mode afterwards, so just can continue to clamp books.In addition, the quantity of the books that can also clamp is as required regulated the contact position of movable contact and coil, thereby regulates the number of turn of the coil of place in circuit, thereby reaches the controlling magnetic field power, regulates the purpose to the attraction size of movable part.
Further set forth content of the present utility model below in conjunction with Figure of description.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, fixture that the utility model is separated from each other and movable part 7, fixture comprise iron core 1, around the coil 2 of iron core outside, the other end is fixed on the slide rail and can be along movable contact 3, the switch 4 that is connected with coil and the power supply 5 of slide rail slip with the coil contact to be fixed on slide rail 6 on the iron core, an end; Iron core 1 and movable part 7 use magnetization easily, and the soft iron or the silicon steel of demagnetization are made easily again.Movable part 7 can adopt various structures as required neatly, and as structure of falling the T-shape or slab construction, present embodiment is the structure of falling the T-shape.Power supply 5 can adopt dry cell, the AC power of also can pegging graft.
The course of work is as follows: when switch 4 is placed open mode, coil 2 produces magnetic field, iron core 1 is magnetized, form an electromagnet, movable part 7 is produced an attraction, thereby books are clamped automatically, when need take out books, only need switch 4 is placed closed condition, this moment, coil 2 magnetic fields disappeared, and iron core 1 also loses magnetism, attraction to movable part 7 disappears thereupon, just can like a cork books be taken out, can once more switch 4 be placed open mode afterwards, so just can continue to clamp books.In addition, the quantity of the books that can also clamp is as required regulated the contact position of movable contact 3 and coil 2, thereby regulates the number of turn of the coil 2 of place in circuit, thereby reaches the controlling magnetic field power, regulates the purpose to the attraction size of movable part 7.
Claims (3)
1. can clamp the book end of books automatically, comprise the fixture and the movable part (7) that are separated from each other, it is characterized in that, fixture comprises iron core (1), around the coil (2) of iron core outside, the other end is fixed on the slide rail and can be along movable contact (3), the switch (4) that is connected with coil and the power supply (5) of slide rail slip with the coil contact to be fixed on slide rail (6) on the iron core, an end; Iron core (1) and movable part (7) are soft iron or silicon steel spare.
