Description

Service creeper

Technical Field

The invention relates to the technical field of automobile maintenance, in particular to a lying plate for automobile maintenance.

Background

During auto repair, because chassis is lower, need the maintainer to bore into and inspect below chassis during maintenance, all adopt the mode of spreading a mat below the car to maintain traditionally, but this can let the maintainer can't freely remove below the ground, and it is inconvenient to go into and come out in addition, though also have dedicated service creeper on the existing market, but the too big inconvenient carrying of volume.

In order to solve the above problems, for example, the patent numbers are: 201721582441.2, 'a service creeper' includes first service creeper, first service creeper is hollow structure, the both sides inner wall of first service creeper all is equipped with the slide rail, and the slide rail has the second service creeper through pulley sliding connection, provides convenience for the maintainer to carry out maintenance work in the car bottom. This patent has realized the effect that removes in car bottom portable, but at the vehicle bottom, is difficult to the application of force and removes the service creeper, and especially hand because the restriction of vehicle chassis height can't make the service creeper remove through upset elbow application of force, and it is convenient not enough relatively to operate. Secondly, the lying plate provided with the wheels is difficult to control the starting and stopping processes, is easy to move autonomously, and cannot be accurately positioned at the position to be repaired, so that the final operation is inconvenient.

In order to solve the problems, the scheme is developed accordingly.

Detailed Description

The invention is explained in more detail below with reference to the figures and examples.

As shown in fig. 1-6: a service creeper for auto repair comprises a creeper 1, wherein four sides of the creeper 1 are connected with rollers 2 through rotating shafts. Be equipped with rack 3 on service creeper 1, rack 3 is equipped with two for supply the shank to place, and all can carry out the rotation of horizontal direction relatively service creeper 1. A first baffle 4 positioned on the inner side of the placing rack 3 and a second baffle 5 positioned on the outer side of the placing rack 3 are respectively arranged on the two placing racks 3. The two placing racks 3 are respectively and symmetrically arranged on two sides of the lying plate 1.

One leg of a maintenance worker is placed on the outer side of the first inner side baffle 4, and the other leg of the maintenance worker is placed on the inner side of the second outer side baffle 5, so that the two placing frames 3 can rotate inwards or outwards simultaneously by controlling the force application of the leg parts. Simultaneously two rack 3 symmetries set up, more are favorable to the even application of force of shank.

Be equipped with linkage member 6 between the rack 3, the below of service creeper 1 is equipped with drive component 7, and drive component 7 links to each other with linkage member 6, and at the rotation in-process of two racks 3, can drive linkage member 6 and cooperation drive component 7 for gyro wheel 2 moves about.

Wherein two rack 3 can carry out the horizontal rotation to inboard or outside simultaneously under aggregate unit's linkage, and its pivoted angle is 15-75 to use the axis of lying board 1 as the normal. Because the linkage device is arranged between the two placing frames 3, the two placing frames 3 cannot rotate by 0-90 degrees, wherein 15 degrees are the angle between the two placing frames 3 under the normal state, and 75 degrees are the maximum angle which can be reached under the driving of the leg movement, so that the end point angles (15 degrees, 75 degrees and 150 degrees) in the embodiment are about values and are not completely accurate values.

The linkage member 6 comprises a first connecting rod 61, a second connecting rod 62, a supporting seat 63 and a linkage block 64. One end of the first connecting rod 61 and one end of the second connecting rod 62 are hinged to the two placing frames 3 respectively, and the other ends of the first connecting rod and the second connecting rod are hinged to the supporting seat 63. The first connecting rod 61 and the second connecting rod 62 are horizontally arranged on the placing rack 3, and an included angle between the first connecting rod 61 and the second connecting rod 62 is always consistent with an included angle between the two placing racks 3. The bottom of the support base 63 is connected with a linkage block 64. The included angle range between the first connecting rod 61 and the second connecting rod 62 and the included angle range between the two placing racks 3 are both 30-150 degrees, and the included angle is twice of the 15-degree included angle and the 75-degree included angle.

The drive member 7 comprises a screw 72 with a copper bush 71, a first gear 73, a second gear 74. The first gear 73 is arranged on the rotating shaft of the connecting roller 2 at one side far away from the placing rack 3, and the second gear 74 is fixedly sleeved on the copper sleeve 71. The first gear 73 and the second gear 74 are meshed with each other. One end of the screw 72 is connected to the linkage block 64.

The connection of the screw 72 to the support block is not threaded.

The second gear 74 is fixedly connected with the copper sleeve 71, so that the copper sleeve 71 can drive the second gear 74 to rotate in the rotating process. The second gear 74 is meshed with the first gear 73, so that the first gear 73 is fixed in the horizontal direction, and the screw 72 moves back and forth in the horizontal direction to always drive the copper sleeve 71 to rotate in the horizontal direction and drive the roller 2 to rotate.

The bottom of lying plate 1 is provided with spacing seat 9 matched with second gear 74, and spacing seat 9 is used for transversely spacing second gear 74, prevents that second gear 74 from appearing the sideslip phenomenon in screw 72 horizontal migration in-process, and leads to breaking away from and unable meshing with first gear 73, influences lying plate 1's normal use. As shown in fig. 5, the limiting seat 9 is a rectangular body with a groove, wherein the groove faces one side of the second gear 74 and has a size matching with that of the second gear 74.

The use process comprises the following steps: the body is laid on the lying plate 1, one leg is placed on the outer side of the first inner side baffle 4, the other leg is placed on the inner side of the second outer side baffle 5, the two placing frames 3 are driven to rotate inwards by inward force application of the legs, the first transmission connecting rod 61 and the second transmission connecting rod 62 drive the supporting seat 63 to move to the side far away from the lying plate 1, the screw 72 is connected with the linkage block 64, the screw 72 also moves along with the screw, and the copper sleeve 71 and the first gear 73 are driven to rotate, so that the roller 2 rotates; otherwise, the leg is applied with force outwards to drive the two placing frames 3 to apply force outwards at the same time, so that the roller 2 rotates reversely.

In this embodiment, according to the setting, the size between the first gear 73 and the second gear 74 can be adjusted, so that the adjustment of the displacement length of the lying plate 1 in the horizontal direction can be realized, but because the back-and-forth movement of the lying plate 1 only depends on the legs to drive the placing rack 3 to rotate, and the angle at which the placing rack 3 can rotate is limited, the stroke of the lying plate 1 which can move is also limited, and only fine adjustment can be performed, but large displacement adjustment cannot be performed.

The lying plate 1 is provided with a soft cushion 8 for the head to lean against, so that the head can be conveniently leaned on in the long-time maintenance process, and the maintenance comfort of maintenance personnel is improved.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and the protection scope thereof must be determined by the scope of the claims.
