Description

Placement joint of portable plug

Technical Field

The utility model relates to a jack, in particular to a placement joint of a portable plug.

Background

The jack adopts two operation methods when lifting the automobile:

As shown in fig. 5, for the new energy vehicle, an auxiliary plug 21 needs to be placed on the tray of the jack to lift, otherwise, the bottom of the new energy vehicle is damaged;

For a common fuel automobile, a special clamping groove is formed in the bottom of the automobile, and a jack can lift only by aligning with the clamping groove without adopting an auxiliary plug.

As shown in fig. 6, in order to place the auxiliary jack on the jack for convenient access and storage, holes are typically formed in the lifting arm and the wall panel of the jack, and the auxiliary jack may be placed in a corresponding hole site 30. However, the structure of the jack can be damaged by the mode, the bearing capacity of the jack is affected, the production process of the jack can be increased, and the production cost is increased.

Disclosure of utility model

The utility model aims to overcome the defects in the background technology and provide a convenient joint for placing a jack, which has the characteristics of simple structure, convenient operation and no damage to the jack structure.

The technical scheme of the utility model is as follows:

The utility model provides a place joint of portable top which characterized in that: the joint is provided with an axially extending central hole, the central hole comprises an upper hole, a middle hole and a lower hole, the inner diameter of the lower hole is larger than that of the upper hole, the inner diameter of the upper hole is larger than that of the middle hole, and the inner wall of the middle hole is provided with internal threads.

The inner diameter of the upper hole is matched with the outer diameter of the head of the auxiliary plug.

The inner diameter of the middle hole is matched with the outer diameter of a bolt for fixing the universal rear wheel.

The inner diameter of the lower hole is matched with the outer diameter of a nut for fixing the universal rear wheel.

The joint is made of metal.

The beneficial effects of the utility model are as follows:

The utility model is placed at the rear wheel frame of the jack, directly utilizes the existing structure of the jack, does not need to change the jack, does not damage the performance of the jack, is simple to install and is convenient for storing and taking auxiliary jacks.

The device comprises a connector 1, an upper hole 2, a middle hole 3, a lower hole 4, a wallboard 11, a front wheel 12, a rear wheel frame 13, a universal rear wheel 14, a press handle 15, a handle 16, a lifting arm 17, a tray 18, bolts 19, nuts 20, an auxiliary top 21, a base 22, a head 23 and a hole site 30.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 5, the conventional jack includes a wall plate 11, a front wheel 12, a rear wheel frame 13, a universal rear wheel 14, a press handle 15, a handle 16, a lifting arm 17, and a tray 18. The universal rear wheel is connected to the rear wheel frame by means of bolts 19 and secured by nuts 20 which extend a certain length out of the nuts so that several threads are exposed (the utility model uses the exposed threads for securing).

As shown in fig. 3, the auxiliary plug 21 includes a base 22 and a head 23.

As shown in fig. 2, a portable plug is provided with a fitting 1 having an axially extending central bore extending through both ends of the fitting. The central hole comprises an upper hole 2, a middle hole 3 and a lower hole 4 which are sequentially communicated from top to bottom. The joint is made of metal, or plastic or rubber.

The inner diameter of the lower hole is larger than that of the upper hole, and the inner diameter of the upper hole is larger than that of the middle hole. The inner diameter of the upper hole is matched with the outer diameter of the head part of the auxiliary plug, the inner diameter of the middle hole is matched with the outer diameter of a bolt for fixing the universal rear wheel, and the inner diameter of the lower hole is matched with the outer diameter of a nut for fixing the universal rear wheel. The inner wall of the middle hole is provided with an internal thread, and the middle hole can be engaged with the screw thread of the bolt.

The utility model is directly connected on a bolt of a universal rear wheel in a threaded manner, wherein a middle hole is in threaded engagement with the bolt, a lower hole surrounds a nut, and an upper hole is used for placing an auxiliary plug.

The auxiliary plug is not needed for lifting the fuel oil car, so the auxiliary plug is reversely placed on the utility model, and the head of the auxiliary plug is downwards inserted into the upper hole. When lifting new energy, the auxiliary plug is required to be used, the auxiliary plug is taken off from the novel energy lifting device and placed on the tray, and then the handle is operated to lift.

The jack is directly arranged on the existing jack, so that the jack is simple in structure, convenient to use, free of modification of the jack structure, capable of being directly matched with a sold jack, and convenient to take and store, and assists in taking and storing the jack; each jack may be provided with one or two placement joints.

Preferred embodiments of the present utility model are shown in the drawings. This utility model may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
