Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] As shown in the figure, the present invention includes a casing, and the inner disk of the casing has a joint chain 4, a positioning screw 10 and a driving device. The head of joint chain 4 is provided with conducting live bell 1. The driving device includes a bull gear 12, a drive assembly and a motor 8, and the bull gear 12 meshes with the pinion 15 of the drive assembly. The driving assembly is connected with the motor 8 . The bull gear 12 is provided with a sleeve hole, and five triangular protruding citrons 14 are arranged on the hole wall of the sleeve hole. Before the joint chain 4 is lifted around the positioning screw rod 10, the guiding live bell 1 is screwed on the positioning screw rod 10. Five triangular grooves 2 are arranged on the leading live bell 1, and the grooves 2 of the leading live bell are fastened with the protruding c...

Abstract

The invention discloses a joint lifter. The joint lifter comprises a case, wherein a joint chain, a positioning screw and a driving device are arranged in the case; the head of the joint chain is provided with a guide moving bell; the driving device comprises a gear wheel, a driving component and a motor; the gear wheel is engaged with a pinion wheel of the driving component; a flange is arrangedon a bore wall of the gear wheel trepanned with bores; before the joint chain is lifted around the positioning screw, the guide moving bell is screwed on the positioning screw, and a groove of the guide moving bell is buckled with the flange of the gear wheel; after the joint chain is lifted around the positioning screw, the joint chain is deformed to form joint sections so as to form a joint lifting column provided with a groove; the top end of the joint lifting column is buckled with the guide moving bell; and the vertically adjacent joint sections are buckled with one another.

Description

technical field [0001] The invention relates to a device for lifting, in particular to a joint lifter. Background technique [0002] Existing drive lifting (telescopic) device is made up of straight line conduit or guide rail, and it can directionally lift (telescopic), but the distance of its lifting (telescopic) is limited by the length of conduit or guide rail, therefore, such as lifting (telescopic) When the distance is large, the volume of the driving lifting (telescopic) device will be very large, resulting in inconvenience in use, carrying and moving. Contents of the invention [0003] The purpose of the invention is to design a joint lifter. [0004] The present invention aims to solve the problem that the lifting (telescopic) distance of the existing drive lifting (telescopic) device is limited by the length of the conduit or guide rail. [0005] In order to achieve the above object, the technical scheme adopted in the present invention is: [0006] The present...
