DETAILED DESCRIPTION

[0023] The first embodiment of the present application is:

[0024] See also Figure 1-Figure 3 ,in, Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model. Figure 2 It is a cross-sectional view of the front side of the first embodiment of the utility model. Figure 3 It is a cross-sectional view of the side of the first embodiment of the utility model.

[0025] The utility model provides a portable inertial navigation device including a base 101, an inertial navigation device body 102 and a portable component 103. The portable component 103 includes a connecting rod 104, a rotating part 105, a hand-held component 106, a limiting component 107, a connecting ear 109, a driving rod 110, a rotating bead 111, a mounting component 112, an adsorption component 113 and an anti-slip pattern 114. The above-mentioned solution solves the problem that it is inconvenient to carry the inertial navigation device alone, thereby causing inconvenience.

[0026] For this specific implementation, the inertial navigation device body 102 is fixedly connected to the base 101 and is located on one side of the base 101. The base 101 serves as a reference for installing the inertial navigation device body 102 parallel to the ground to ensure that the inertial navigation device body 102 is stably installed when working. The specific structure and use method of the inertial navigation device body 102 are recorded in the patent document with publication number CN215491748U, which is not within the protection scope of this application and will not be described in detail here.

[0027] The inertial navigation device body 102 has a groove 108, and the groove 108 is located on one side of the inertial navigation device body 102. The connecting rod 104 is fixedly connected to the inertial navigation device body 102 and is located on one side of the inertial navigation device body 102. The two rotating parts 105 are respectively arranged at both ends of the connecting rod 104. The handheld component 106 is arranged on one side of the rotating part 105. The stopper 107 is fixedly connected to the connecting rod 104 and is located on one side of the connecting rod 104. The grooves 108 are provided on both sides of the inertial navigation device body 102. The connecting rod 104 passes through the inertial navigation device body 102 and is located at the center of the groove 108. The limiting member 107 is located at the center of the connecting rod 104 as a limit for the rotating parts 105 at both ends. The rotating parts 105 are always located at the two end positions of the connecting rod 104 under the restrictions of the limiting member 107 and the inertial navigation device body 102. The hand-held parts 106 on both sides of the inertial navigation device body 101 can be rotated to break away from the restriction of the groove 108, thereby increasing the fulcrum points for hand-held use, thereby making it easier to carry the inertial navigation device body 102.

[0028] Secondly, the connecting ear 109 is rotatably connected to the connecting rod 104 and is located on one side of the connecting rod 104. The two driving rods 110 are respectively fixedly connected to the connecting ear 109 and are located on both sides of the connecting ear 109. A plurality of rotating beads 111 are arranged between the driving rod 110 and the connecting rod 104. The connecting ears 109 are respectively installed on both sides of the connecting rod 104 and can be rotated on the connecting rod 104. When it is necessary to lift the inertial navigation device body 102, the hand piece 106 is buckled out of the groove 108. When the hand piece 106 rotates, the driving rod 110 rotates in the inertial navigation device body 102 and the limiting member 107, thereby driving the rotating beads 111 to rotate quickly between the driving rod 110 and the connecting rod 104, making the whole process smoother and facilitating the quick removal of the hand piece 106 from the groove 108.

[0029] At the same time, the mounting member 112 is fixedly connected to the handheld member 106 and is located on one side of the handheld member 106. The adsorbent 113 is fixedly connected to the inertial navigation device body 102 and is located on one side of the inertial navigation device body 102. The adsorbent 113 adsorbs the mounting member 112. When it is not necessary to carry it by hand, the handheld member 106 is rotated to the inside of the groove 108. The adsorbent 113 adsorbs the mounting member 112 on the handheld member 106 and stabilizes it in the groove 108 without swinging, thereby reducing the occupied space. When needed, the handheld member 106 is pulled to separate the mounting member 112 from the adsorption of the adsorbent 113, and the handheld member 106 is rotated upward to increase the fulcrum, so as to facilitate carrying the inertial navigation device body 102.

[0030] In addition, the anti-slip pattern 114 is fixedly connected to the hand piece 106 and is located on one side of the hand piece 106 . The anti-slip pattern 114 is more convenient when lifting the inertial navigation device body 102 , and increases friction to facilitate better carrying of the inertial navigation device body 102 .

[0031] When using the utility model, the hand piece 106 is buckled out of the groove 108 and then rotated upward. The rotation of the hand piece 106 causes the mounting member 112 to be separated from the adsorption of the adsorption member 113 and exposed outside the groove 108. While rotating, the driving rod 110 rotates in the inertial navigation device body 102 and the limiting member 107, thereby driving the rotating bead 111 to rotate rapidly between the driving rod 110 and the connecting rod 104. The hand piece 106 is held upwardly perpendicular to the inertial navigation device body 102, and the inertial navigation device body 102 is lifted by holding the anti-slip groove 114, so that it is easy to carry it alone and more convenient to go to different places for work.

[0032] The second embodiment of the present application is:

[0033] Based on the first embodiment, please refer to Figure 4-Figure 5 ,in, Figure 4 It is a schematic diagram of the overall structure of the second embodiment of the utility model. Figure 5 It is an overall cross-sectional view of the second embodiment of the utility model. The portable inertial navigation device provided by the utility model further includes a mounting assembly 201 . The mounting assembly 201 includes a support rod 202 , a cylinder 203 and an extension rod 204 .

[0034] According to this specific embodiment, the support rod 202 is fixedly connected to the base 101 and is located on one side of the base 101. The cylinder 203 is fixedly connected to the support rod 202 and is located inside the support rod 202. The extension rod 204 is fixedly connected to the output end of the cylinder 203 and is slidably connected to the support rod 202 and is located on one side of the cylinder 203. The cylinder 203 is installed inside the support rod 202. When installing the inertial navigation unit body 102, it may be inconvenient to install due to the uneven ground. The extension rod 204 is driven to retract and retract through the output end of the cylinder 203, thereby adjusting the different heights of the four corners for easy flat placement.

[0035] When using the utility model, the hand piece 106 is buckled out of the groove 108 and then rotated upward. The rotation of the hand piece 106 causes the mounting member 112 to be separated from the adsorption of the adsorption member 113 and exposed outside the groove 108. While rotating, the driving rod 110 rotates in the inertial navigation device body 102 and the limiting member 107, thereby driving the rotating bead 111 to rotate rapidly between the driving rod 110 and the connecting rod 104. The hand piece 106 is vertically upward to the inertial navigation device body 102, and the inertial navigation device body 102 is lifted by holding the anti-slip groove 114 position, so that it is convenient to carry it alone and more convenient to go to different places for work. Then, according to the height of the ground on site, the cylinder 203 is started, and the extension rod 204 is driven by the cylinder 203 to be extended and retracted in the support rod 202, so that it can be placed stably on uneven ground.

Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
