DETAILED DESCRIPTION
[0020] Embodiment 1
[0021] See also Figure 1 , the utility model provides the following technical solutions:
[0022] Specifically, it refers to an electric jack which is easy to maintain, comprising a connecting shell 1, and a servo motor 2 and a supporting assembly are respectively arranged on the sides of the connecting shell 1.
[0023] Specifically, the support assembly includes an articulated base 301 and a support base 302, and the articulated base 301 and the support base 302 are arranged in a vertical mirror image. Two first articulated plates 303 are hinged on the articulated base 301, and two second articulated plates 304 are hinged on the lower side of the support base 302. The lower sides of the two second articulated plates 304 are respectively hinged to the upper sides of the two first articulated plates 303, and the second articulated plates 304 are rotatably connected to the inner side of the first articulated plates 303, and a screw 306 is provided between the two connecting blocks 305. One end of the screw 306 rotates to penetrate the connecting block 305 close to the connecting shell 1, and the other end is threadedly penetrated through the connecting block 305 on the other side.
[0024] When in use, by rotating one end of the screw rod 306 close to the connecting shell 1, the connecting block 305 on the other side is displaced on the screw rod 306 under the threaded transmission of the screw rod 306, thereby synchronously driving the first hinge plate 303 and the second hinge plate 304 to move. At the same time, the angle between the first hinge plate 303 and the second hinge plate 304 changes. When the hinge base 301 is placed on the ground, it can drive the support base 302 to move upward or downward.
[0025] Embodiment 2
[0026] See also Figure 2 Specifically, the connecting shell 1 includes a first shell 101 and a second shell 102. The servo motor 2 is fixedly installed on the side of the first shell 101 by bolts. The first shell 101 and the second shell 102 are combined to form the connecting shell 1. Two mounting tenons 103 are fixedly connected to the surface of the first shell 101 facing the second shell 102. The two mounting tenons 103 are respectively arranged on the upper and lower sides of the cavity of the first shell 101. The mounting tenons 103 are in the shape of a water drop. Two mounting tenons 104 are provided on the surface of the second shell 102 facing the first shell 101. The mounting tenons 104 are adapted to the mounting tenons 103 and extend out of the side of the second shell 102 facing away from the supporting assembly. When the first shell 101 and the second shell 102 are installed, it is only necessary to slide the installation tenon block 103 into the installation tenon groove 104. Since the installation tenon block 103 is in the shape of a teardrop, this avoids the first shell 101 and the second shell 102 from being separated when pulled horizontally. When the servo motor 2 needs to be repaired in the above manner, it is only necessary to remove the first shell 101 from the second shell 102, and then install another first shell 101 with a good servo motor 2 installed on the second shell 102. This operation method will not affect the normal use of the electric jack when repairing the servo motor 2, and the damaged servo motor 2 can be maintained separately, thereby ensuring the use effect of the electric jack.
[0027] Specifically, a first gear 107 is rotatably connected in the second shell 102, and a connecting block 305 close to one side of the connecting shell 1 is fixedly installed on the side of the second shell 102. One end of the screw 306 rotates and penetrates into the second shell 102 and is fixedly connected to the first gear 107. A second gear 108 is rotatably connected in the first shell 101. One end of the output shaft of the servo motor 2 rotates and penetrates into the first shell 101 and is fixedly connected to the second gear 108. One side of the second gear 108 extends out of the first shell 101 and is meshed with the first gear 107. In this way, when the electric jack needs to be used, the output shaft of the servo motor 2 is controlled to rotate, which can synchronously drive the second gear 108 to rotate. At the same time, the second gear 108 meshes and transmits the rotation of the first gear 107, so that the screw 306 rotates synchronously with the first gear 107.
[0028] Specifically, an extension groove 106 connected to the interior of the second shell 102 is provided on a side away from the supporting assembly, so that when the first shell 101 and the second shell 102 are installed, the second gear 108 extending out of one side of the first shell 101 can slide into the second shell 102 through the extension groove 106 and engage with the first gear 107. An extension plate 105 that matches the extension groove 106 is fixedly installed on one side of the first shell 101 close to the extension groove 106, and the extension groove 106 is blocked by the extension plate 105.
[0029] Embodiment 3
[0030] See also Figure 3-4 Specifically, a second docking block 110 is fixedly installed on the upper surface of the first shell 101, and a first docking block 109 is fixedly installed on the upper surface of the second shell 102. A slider 112 is fixedly connected to the side surface of the second docking block 110 facing the first docking block 109. The slider 112 is a right-angled trapezoid. A slide groove 111 adapted to the slider 112 is opened on the side surface of the first docking block 109 facing the second docking block 110, and the slide groove 111 extends out of the side of the first docking block 109 facing away from the supporting assembly. When the first shell 101 and the second shell 102 are docked, the slider 112 slides horizontally into the slide groove 111.
[0031] Specifically, a pin hole 113 is provided on the slider 112, and a pin shaft 114 is provided on the first docking block 109. The lower end of the pin shaft 114 slides through the slide groove 111, and the lower end of the pin shaft 114 is consistent with the pin hole 113. Therefore, when the lower end of the pin shaft 114 slides into the pin hole 113, the pin shaft 114 can form a restrictive effect on the slider 112 to prevent the slider 112 from separating from the slide groove 111, thereby completing the fixation between the first shell 101 and the second shell 102.
[0032] Specifically, a sliding cavity 115 is opened in the first docking block 109, and a section of the pin shaft 114 is arranged in the sliding cavity 115. The pin shaft 114 is located on the outer surface of the sliding cavity 115 and is fixedly sleeved with a limiting plate 116. A spring 117 is fixedly connected between the upper surface of the limiting plate 116 and the top wall of the sliding cavity 115. When the spring 117 is not squeezed, the spring 117 will exert a thrust on the limiting plate 116, so that the lower end of the pin shaft 114 extends into the sliding groove 111. In this way, the spring 117 exerts a limiting effect on the pin shaft 114, thereby avoiding the separation between the first shell 101 and the second shell 102 when the electric jack is in use, thereby ensuring the stability of the electric jack when in use.
[0033] The working principle of the electric jack provided by the utility model, which is easy to maintain, is as follows: when the first housing 101 and the second housing 102 are installed, it is only necessary to slide the installation tenon block 103 into the installation tenon groove 104, and at the same time, the second gear 108 extending out of the first housing 101 can slide into the second housing 102 through the extension groove 106 and mesh with the first gear 107;
[0034] When it is necessary to support an object, the output shaft of the servo motor 2 is controlled to rotate, which can synchronously drive the second gear 108 to rotate. At the same time, the second gear 108 meshes and transmits the first gear 107 to rotate, so that the screw 306 rotates synchronously with the first gear 107, and the connecting block 305 on the other side is displaced on the screw 306 under the threaded transmission of the screw 306, thereby synchronously driving the first hinge plate 303 and the second hinge plate 304 to displace. At the same time, the angle between the first hinge plate 303 and the second hinge plate 304 changes. When the hinge base 301 is placed on the ground, it can drive the support base 302 to move upward or downward.
