Detailed Description
Referring to fig. 1-4, the present invention provides the following technical solutions: the utility model provides a jack for domestic automobile maintenance, is including the base 1 that plays support and installation effect and be used for carrying out the jack-up structure 2 of jack-up to the automobile body, just jack-up structure 2 install in the top of base 1, the bottom of base 1 is equipped with and is used for removing the cylinder 4 of base 1, the inboard of jack-up structure 2 is equipped with carries out rotatory spanner 3 to the threaded rod when using.
In this embodiment: when the jack is needed to be used, firstly, the containing plate 13 in the sliding groove 12 slides outwards, at the moment, the external acting force of the roller 4 disappears, at the moment, the roller 4 pops outwards under the action of the reset spring 42, the bottom of the popped roller 4 is lower than the bottom of the base 1, a user can push the base 1 to adjust the position of the jack to the lower part of the vehicle body through the roller 4, after the jack moves to a proper position, at the moment, a worker takes the wrench 3 off, rotates the threaded rod in the jacking structure 2 through the wrench 3, adjusts the included angle between the supporting rods in the jacking structure 2 through the rotation of the threaded rod, in the process that the jacking structure 2 ascends, the acting force acting on the top of the base 1 gradually increases when the top of the jacking structure 2 contacts the bottom of the vehicle body, at the moment, the acting force on the top of the roller 4 synchronously increases, and the roller 4 contracts while being pressed, the roller 4, which is originally in direct contact with the ground, is in direct contact with the ground from the bottom of the base 1 by contraction and plays a supporting role.
The top of the roller 4 is provided with a mounting plate 41 for mounting the roller 4, and the roller 4 is rotatably connected to the inner walls of two sides of the mounting plate 41; wherein the rollers 4 are uniformly distributed below the mounting plate 41 along one side of the mounting plate 41, and the movement of the base 1 is completed through the connection of the mounting plate 41.
The top of the mounting plate 41 is fixedly connected with a return spring 42 which resets the top of the roller 4 after the external pressure is lost; after base 1 passes through the removal that cylinder 4 accomplished the position, in order to prevent that cylinder 4 from causing the problem of rocking in the course of the work of jack, this moment under reset spring 42's effect, when the top effort increase of base 1, reset spring 42 can drive cylinder 4 and contract to the inside of mounting groove 11, avoids the unstable problem that cylinder 4 caused at the jack use.
The bottom of the base 1 is fixedly connected with a mounting groove 11 for mounting the return spring 42, and the top end of the return spring 42 is fixedly connected to the inside of the mounting groove 11; wherein the mounting groove 11 is a moving space where the drum 4 is contracted inward and is used for mounting the return spring 42.
The bottom position of the roller 4 is positioned below the bottom position of the base 1; at this moment, the roller 4 can move the position of the base 1 through rolling, and abrasion to the bottom of the base 1 caused by direct dragging is avoided.
A fixing groove 21 for placing the wrench 3 is formed in an inner cavity of the supporting arm for supporting in the jacking structure 2, and the fixing groove 21 is an imitated groove at two ends of the wrench 3; need rotate the screw rod through spanner 3 when being used for when using, accomplish the adjustment to the height of jack-up structure 2, thereby carry out the jack-up work to the automobile body, and accomodate spanner 3 after finishing using in jack-up structure 2, can accomplish the work of accomodating spanner 3 on the one hand, avoid the condition that spanner 3 lost appearing in the use, on the other hand, can spanner 3 can play the dead effect of lock to the bracing piece in the jack-up structure 2 that bilateral symmetry set up in jack-up structure 2, improve the stability under unused state, thereby can improve the condition of not using
The bottom of the base 1 is symmetrically embedded with sliding chutes 12 playing a role in movement; wherein the sliding groove 12 is used for sliding and connecting the receiving plate 13.
The working principle and the using process of the utility model are as follows: when the jack is needed to be used, firstly, the containing plate 13 in the sliding groove 12 slides outwards, at the moment, the external acting force of the roller 4 disappears, at the moment, the roller 4 is outwards popped out under the action of the reset spring 42, the bottom of the popped roller 4 is lower than the bottom of the base 1, a user can push the base 1 to adjust the position of the jack to the lower part of the vehicle body through the roller 4, after the jack moves to a proper position, at the moment, a worker takes the wrench 3 off the fixed groove 21, rotates the threaded rod in the jacking structure 2 through the wrench 3, adjusts the included angle between the supporting rods in the jacking structure 2 through the rotation of the threaded rod, in the process that the jacking structure 2 rises, the acting force acting on the top of the base 1 gradually increases when the top of the jacking structure 2 contacts the bottom of the vehicle body, at the moment, the acting force on the top of the roller 4 synchronously increases, and the roller 4 contracts towards the inside of the mounting groove 11 while being pressed, at this moment, the roller 4 originally in direct contact with the ground is in direct contact with the ground from the bottom of the base 1 through contraction and plays a supporting role, the roller 4 positioned in the installation groove 11 can increase the friction force between the roller 4 and the ground under the reaction force of the return spring 42, the possibility of shaking of the roller 4 in the use process is reduced, after the use is finished, the jacking structure 2 is firstly descended downwards through the wrench 3, when the jacking structure 2 is descended to the lowest position, the wrench 3 can be placed between the support rods symmetrically arranged in the jacking structure 2 through the fixing groove 21, the support rods in the jacking structure 2 can be locked while the wrench 3 is stored, the jack is prevented from being deformed due to the influence of external shaking in the unused state, meanwhile, the storage plate 13 is slidably connected to the bottom of the base 1 through the sliding groove 12 by a user, accomodate cylinder 4 for cylinder 4 contracts to the inside of mounting groove 11 under unused state, avoids cylinder 4 to appear rocking the condition at the car in-process that traveles.
