Description

Height-adjustable hook

Technical Field

The utility model belongs to the technical field of the couple, especially, relate to a height-adjustable couple.

Background

The hook is used for hanging articles. After the traditional hook is hung on an object, the height of the hook is fixed, and the hook is not suitable for people with different heights.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the technical problem and providing a height-adjustable hook which can be suitable for people with different heights.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a height-adjustable couple, includes mobile jib, telescopic link, couple and lifting hook, the telescopic link cover is established in the mobile jib and with the scalable connection of mobile jib, the couple is fixed to be set up on the mobile jib, the lifting hook is fixed to be set up the telescopic link top, be equipped with a plurality of spacing draw-in grooves along length direction on the telescopic link outer wall, be equipped with the ball mounting groove on the mobile jib inner wall, install pressure spring and magnetic force ball in the ball mounting groove, the pressure spring will the magnetic force ball is impressed spacing draw-in groove, be in on the mobile jib the outside of magnetic force ball is equipped with magnetic induction coil, magnetic induction coil is connected with.

Preferably, the couple includes a set of couple at least, and every group couple includes two couples at least, and each couple of every group couple is followed mobile jib circumference evenly sets up, magnetic induction coil sets up in the couple.

Preferably, the main lever includes an inner sleeve, and the ball mounting groove, the pressing spring and the magnetic ball are provided on the inner sleeve.

After the technical scheme is adopted, the utility model has the advantages of as follows:

the utility model discloses a height-adjustable couple, when magnetic induction coil switched on, the magnetic force ball was attracted by magnetic induction coil and breaks away from spacing draw-in groove for mobile jib and telescopic link relative movement, the pressure spring was compressed this moment, and the mobile jib falls for the telescopic link because of gravity. When the main rod is lowered to the expected height, the magnetic induction coil is powered off, and the magnetic ball is ejected out under the action of the elastic force of the pressure spring. If the magnetic ball is aligned with the limiting clamping groove, the magnetic ball is directly clamped into the limiting clamping groove; if the magnetic ball is not aligned to the limiting clamping groove, the main rod continues to fall down, the magnetic ball rolls on the outer wall of the telescopic rod until the magnetic ball is clamped into the limiting clamping groove, and the main rod and the telescopic rod are relatively fixed. When resetting, only the lower end of the main rod is required to be supported and the main rod is jacked up to enable the telescopic rod to retract into the main rod. The utility model discloses a height-adjustable couple for the height-adjustable of couple, thereby be suitable for the people of high difference to use.

The present invention will be further explained with reference to the accompanying drawings:

fig. 1 is a schematic structural view of a height-adjustable hook of the present invention;

FIG. 2 is a front view of a height adjustable hook of the present invention;

FIG. 3 is a cross-sectional view taken at A in FIG. 2;

in the figure:

1-a main rod; 101-ball mounting grooves; 102-an inner sleeve; 2, a telescopic rod; 201-a limiting clamping groove; 3-hooking; 4-a magnetic induction coil; 5-a pressure spring; 6-magnetic ball bearing; 9-a hook.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-2, a height-adjustable couple, includes mobile jib 1, telescopic link 2, couple 3 and

lifting hook

9, 2 covers of telescopic link are established in the mobile jib 1 and with mobile jib 1 telescopic connection, couple 3 is fixed to be set up on the mobile jib 1, lifting hook 9 is fixed to be set up 2 tops of telescopic link.

As shown in fig. 1 to 3, a plurality of limiting clamping grooves 201 are formed in the telescopic rod 2 along the length direction of the telescopic rod 2, the main rod 1 includes an inner sleeve 102, the inner sleeve 102 is provided with a ball mounting groove 101, a pressure spring 5 and a magnetic ball 6 are mounted in the ball mounting groove 101, the magnetic ball 6 is pressed into the limiting clamping grooves 201 by the pressure spring 5, and the magnetic ball 6 is clamped in the limiting clamping grooves 201 to fix the main rod 1 and the telescopic rod 2. The magnetic induction coil 4 is arranged on the outer side of the magnetic ball 6 on the main rod 1, and the magnetic induction coil 4 is connected with a control circuit.

Preferably, couple 3 includes a set of couple at least, and every group couple includes two couples at least, and each couple of every group couple is followed mobile jib 1 circumference evenly sets up, magnetic induction coil 4 sets up in the couple to be located the hookup 3 and the hookup location department of mobile jib 1. In this embodiment, the upper end and the lower end of the main rod 1 are respectively and fixedly provided with two hooks 3, and the two hooks 3 are symmetrically arranged about the main rod 1. The hook angle of the hook 3 is upward.

When magnetic induction coil 4 circular telegram, magnetic force ball 6 is attracted by magnetic induction coil 4 and breaks away from spacing draw-in groove 201 for mobile jib 1 and telescopic link 2 relative movement, pressure spring 5 is compressed this moment, and mobile jib 1 falls for telescopic link 2 because of gravity. When the main rod 1 descends to a desired height, the magnetic induction coil 4 is powered off, and the magnetic ball 6 is ejected out under the action of the elastic force of the pressure spring 5. If the magnetic ball 6 is aligned with the limit slot 201, the magnetic ball 6 is directly clamped into the limit slot 201; if the magnetic ball 6 is not aligned to the limit slot 201, the main rod 1 continues to fall down at the moment, and the magnetic ball 6 rolls on the outer wall of the telescopic rod 2 until the magnetic ball 6 is clamped into the limit slot 201, so that the main rod 1 and the telescopic rod 2 are relatively fixed. When resetting, only the lower end of the main rod 1 needs to be supported and the main rod 1 is jacked up to enable the telescopic rod 2 to retract into the main rod 1.

To sum up, the utility model discloses a height-adjustable couple for the height-adjustable of couple, thereby be suitable for the people of high difference to use.

In addition to the preferred embodiments described above, other embodiments of the present invention are also possible, and those skilled in the art can make various changes and modifications according to the present invention without departing from the spirit of the present invention, which should fall within the scope of the present invention defined by the appended claims.
