specific Embodiment approach 1

[0007] Specific embodiment one: (referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4) the extravehicular spacesuit glove fingertip vacuum adsorption fixing device of the present embodiment consists of an adsorption cap 2, a connecting shaft 3, an airway joint 5, a first The air guide tube 7, the second air guide tube 11, the miniature vacuum pump 8 with the motor and the air valve 10 are composed. The adsorption cap 2 is connected to the fingertip sensor 6 of the exoskeleton manipulator 1 through the connecting shaft 3, and the first air guide tube 7 One end communicates with the adsorption cap 2 through the air guide tube joint 5, the other end of the first air guide tube 7 communicates with the air inlet of the air valve 10, and the air outlet of the air valve 10 is connected with the input end of the micro vacuum pump 8 with the motor through the second The air duct 11 communicates, and the inner surface of the adsorption cap 2 and the outer surface of the extravehicular space su...

specific Embodiment approach 2

[0008] Embodiment 2: (see FIG. 1 and FIG. 3 ) The contour shape of the inner surface of the adsorption cap 2 in this embodiment is consistent with the contour shape of the outer surface of the fingertip 4 of the extravehicular spacesuit glove. It is designed in this way to make the best adsorption effect. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0009] Specific embodiment three: (see Fig. 1 and Fig. 4) the outer wall of the top end of the adsorption cap 2 described in this embodiment is provided with a connection hole 2-1, and one end of the air guide tube connector 5 is plugged into the connection hole 2-1 Inside. Such a design makes it easy to install and maximizes the adsorption effect. Other components and connections are the same as those in the first embodiment.

Abstract

The invention provides a glove fingertip vacuum absorption fixing device of an extravehicular space suit, which relates to a vacuum absorption fixing device. The invention can solve the problems between the fingertip of an EVA glove which adopts rigid fixing device for connection and the fingertip of an exoskeleton mechanism that the fingertip is easy to break off, the clamping force is difficult to control and the expensive EVA glove is easy to be damaged. An adsorption cap (2) is connected with a fingertip sensor (6) of an exoskeleton manipulator (1) by a connection shaft (3), one end of a first air duct (7) is communicated with the absorption cap (2) by an air duct joint (5), the other end of the first air duct (7) is communicated with an air inlet of an air valve (10), an air outlet of the air valve (10) is communicated with the input end of a micro vacuum pump (8) with an electric motor by a second air duct (11). The invention realizes the flexible connection between the fingertip of the glove of the EVA space suit and the fingertip of the exoskeleton mechanism; the device never breaks off and has no damage to the glove of the expensive EVA space suit.

Description

technical field [0001] The invention relates to a vacuum adsorption fixing device, in particular to a vacuum adsorption fixing device installed on a fingertip of an outer space suit glove. Background technique [0002] When an external measuring device is used to measure the damping force of the fingers of the extravehicular space suit glove (hereinafter referred to as EVA glove), it is necessary to connect the fingertip of the EVA glove with the fingertip of the exoskeleton mechanism. EVA is a flexible joint device mainly made of silk fabrics, especially the fingertips of EVA gloves are made of rubber materials, and its shape is a circular arc surface. The fingertips of the exoskeleton manipulator will easily fall off when they are firmly connected to the fingertips of the exoskeleton manipulator, and the clamping force is not easy to control, and it is easy to damage the expensive EVA gloves. At present, there is no flexible connection device for connecting the fingertips...
