In order to overcome the defects of the prior art, the utility model aims to provide a book end with extension and retraction to solve the problems in the prior art.
A telescopic book end comprises a left backup plate, a telescopic rod, a movable baffle, a right backup plate, a middle layer plate, a bottom plate, a rod head, a short screw, a straight rod, an extension spring, a supporting block, a spring groove, a threaded hole, a long screw, an interlayer and a threaded head; the left backup plate is connected with the right backup plate through a telescopic rod; the middle layer plate is sleeved in the interlayer of the bottom plate and is connected with the right backup plate, and the middle layer plate can be pulled left and right; one side of the straight rod is provided with a rod head, and the other side of the straight rod is provided with a threaded head; the straight rod is sleeved in the extension spring, one side of the extension spring is in contact with the rod head, and the extension spring sleeved with the straight rod is placed in the spring groove of the bottom plate; one side of the straight rod with a threaded head passes through a round hole on the supporting block and is in threaded connection with a threaded hole on the right backup plate; the clamping groove on the movable baffle is clamped on the telescopic rod and can move left and right; the outer diameter of the extension spring is smaller than the inner diameter of the spring groove; the outer diameter of the rod head on the straight rod is larger than the outer diameter of the extension spring and smaller than the inner diameter of the spring groove; the outer diameter of the extension spring is larger than the diameter of the round hole on the supporting block; the straight rod is arranged below the middle layer plate; the bottom plate, the supporting block and the spring groove are integrated.
Furthermore, the quantity of telescopic link is 3.
Further, the number of straight rods is 3.
Further, the number of the extension springs is 3.
The beneficial effects of the utility model are that: the telescopic book end has simple structure and convenient installation; when the books are less and the length capacity of the bottom plate is not enough, the books can be blocked by the movable baffle plate, and the books are not easy to topple; when more books exceed the length capacity of the bottom plate, the length can be increased by using the telescopic book holder, and the book holder can freely stretch under the action of the telescopic spring to clamp the placed books; the books may also be sorted using a movable baffle. Meanwhile, the book clip can be moved together with the books, so that convenience is brought to use.

In the figure: 1. a left backup plate; 2. a telescopic rod; 3. a movable baffle; 4. a right backup plate; 5. a middle layer plate; 6. a base plate; 7. a club head; 8. a short screw; 9. a straight rod; 10. an extension spring; 11. a supporting block; 12. a spring slot; 13. a threaded hole; 14. a long screw; 15. an interlayer; 16. and (4) a thread head.
Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: a book end with extension; the novel telescopic rod comprises a left backup plate (1), a telescopic rod (2), a movable baffle (3), a right backup plate (4), a middle layer plate (5), a bottom plate (6), a rod head (7), a short screw (8), a straight rod (9), a tension spring (10), a supporting block (11), a spring groove (12), a threaded hole (13), a long screw (14), an interlayer (15) and a threaded head (16); firstly, the left backup plate (1) is connected with the bottom plate (6) through a long screw (14), and meanwhile, the left backup plate (1) is connected with the right backup plate (4) through an expansion link (2); the movable baffle (3) is clamped on the telescopic rod (2) to move left and right; the middle layer plate (5) is sleeved in the interlayer (15) in the bottom plate (6), and one side of the middle layer plate is connected with the right backup plate (4) through a short screw (8); the straight rod (9) is sleeved in the extension spring (10), the rod head (7) is in contact with one side of the extension spring (10), the extension spring (10) sleeved with the straight rod (9) is placed in the spring groove (12) in the bottom plate (6), and the threaded head (16) on the straight rod (9) penetrates through a round hole in the supporting block (11) in the bottom plate (6) and is in threaded connection with the threaded hole (13) in the right backup plate (4).
Furthermore, the number of the telescopic rods (2) is 3, and the telescopic rods are arranged between the left backup plate (1) and the right backup plate (4).
Furthermore, the number of the straight rods (9) and the number of the extension springs (10) are 3, and the straight rods and the extension springs are combined and installed in the spring grooves (12).
The utility model has the advantages that: when the right backup plate (4) is pulled by a hand, the middle layer plate (5) can be pulled out, the rod head (7) can be driven to compress the extension spring (10) at the same time, so that an extended space is formed in the book, and the right backup plate (4) returns to the original position under the action of the extension spring (10) after the hand is released. When the books are less and are not arranged in the length capacity of the bottom plate (6), the movable baffle (3) can be used for blocking the books, so that the books are prevented from falling down when the books are less; when the books exceed the length capacity of the bottom plate (6), the middle layer plate (5) can be pulled out by using the telescopic book holder to increase the length, the book holder can be automatically contracted under the action of the telescopic spring (10) and the straight rod (9) after the books are placed, and the books can be classified by using the movable baffle plate (3).
