Description

Automatic mounting tool for TPMS (tire pressure monitor System) inflating valve

Technical Field

The utility model relates to a TPMS inflating valve automatic installation instrument belongs to mechanical technical field.

Background

The existing automobile tire valve is installed on a wheel hub and needs to penetrate through a valve installation hole on a wheel rim, and the valve is clamped in the valve installation hole and forms interference fit with the valve installation hole. The mounting mode of the automobile tire valve usually comprises a knocking type and a pulling type. The knocking type valve is characterized in that the valve is directly installed in place through enough impact force, the knocking type valve has the advantages of high installation speed and the defects of great damage to rubber at the bottom of the valve, rubber cracking is easy to occur, and the TPMS valve is easy to knock an electronic part.

The pull-in type is to pull the inflating valve in place through a mounting tool, the mode needs to unscrew a dustproof cap on the inflating valve, then screw in or clamp the mounting tool, then pull the inflating valve into a rim inflating valve mounting hole of an automobile, finally, unscrew the mounting tool and then screw in the dustproof cap, and the mounting of the inflating valve is completed. The tire inflating valve mounting tool needs to screw down and screw up the dustproof cap at the top of the inflating valve in the mounting process every time, is low in operation speed, influences mounting efficiency and is also insufficient.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned not enough, the utility model provides a TPMS inflating valve automatic installation instrument, the utility model discloses a technical scheme as follows:

an automatic mounting tool for a TPMS valve comprises a cylinder body, a piston arranged in the cylinder body, a cushion block connected to the lower end of the cylinder body, a taper outer sleeve arranged at the lower end of the cushion block through a cover plate, and an inner sleeve arranged in the taper outer sleeve, wherein the lower end of the inner sleeve is movably connected with a hook through a pin, and the upper end of the hook is provided with a reset rubber ring; the cylinder body is separated by a piston to form an upper air chamber and a lower air chamber, a passage for axial movement of a piston rod is arranged in the cushion block, and the upper end of the inner sleeve is connected with the piston rod.

As an improved scheme, a spring expansion device is further installed between the inner sleeve and the piston rod and comprises a lower expansion sleeve connected to the upper end of the inner sleeve, an upper expansion sleeve connected to the lower end of the piston rod and a spring sleeved on the lower expansion sleeve, and the upper end of the lower expansion sleeve is movably connected into the upper expansion sleeve through a connecting pin.

Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model discloses a cylinder block provides the pull-in force, hooks the clearance department between the mouth body of inflating valve and the air cap through the hook, utilizes the tapering overcoat to realize opening and shutting of hook, need not to revolve the degassing cap in the installation, is showing and is improving installation effectiveness, has still avoided the damage to inflating valve. And simultaneously the utility model discloses still be equipped with spring telescoping device, in the hook just leads to the taper outer covering fast when utilizing the resilience force of spring to make the piston begin to pull up, hook and rim contact when avoiding the pull up, scratch rim when preventing that the hook from opening and shutting. The utility model discloses a mounting tool both can install ordinary inflating valve and can install TPMS inflating valve, has not only improved the installation effectiveness, has still solved the fragile problem of inflating valve.

fig. 3 is a schematic view of the usage state of the present invention.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Example 1:

referring to fig. 1-3, an automatic mounting tool for a TPMS valve comprises a cylinder block 1, a piston 2 arranged in the cylinder block 1, a cushion block 3 connected to the lower end of the cylinder block 1, a taper outer sleeve 5 arranged at the lower end of the cushion block 3 through a cover plate 4, and an inner sleeve 6 arranged in the taper outer sleeve 5, wherein a hook 8 is movably connected to the lower end of the inner sleeve 6 through a pin 7, and a reset rubber ring 9 is arranged at the upper end of the hook 8; the cylinder block 1 is partitioned by a piston 2 to form an upper air chamber 10 and a lower air chamber 11, a channel for axial movement of a piston rod 12 is arranged in the cushion block 3, and the upper end of the inner sleeve 6 is connected with the piston rod 12.

When the installation tool is used, the hook hooks a gap between a valve body of the inflating valve and the air cap, the hook does not directly clamp the inflating valve body, then the lower air chamber is inflated to enable the piston to move upwards to drive the hook to be pulled upwards, the hook is closed and guided into the taper outer sleeve through the inner conical surface of the taper outer sleeve, the piston continues to move upwards to the position where the inflating valve is pulled, then the upper air chamber is inflated to enable the piston to move downwards to drive the hook to move downwards to release hooking of the air cap, the installation tool is withdrawn, and the inflating valve is installed completely.

Example 2:

referring to fig. 1-3, the installation tool of the present embodiment is different from embodiment 1 in that a spring expansion device is additionally disposed between the inner sleeve 6 and the piston rod 12, the spring expansion device includes a lower expansion sleeve 13 connected to the upper end of the inner sleeve 6, an upper expansion sleeve 14 connected to the lower end of the piston rod 12, and a spring 15 sleeved on the lower expansion sleeve 13, and the upper end of the lower expansion sleeve 13 is movably connected to the upper expansion sleeve 14 through a connecting pin 16.

The use mode of the installation tool of the embodiment is the same as that of the embodiment 1, and the installation tool has the advantages that when the piston starts to move upwards, the spring rebounds to reset and drives the hook to be quickly guided into the taper outer sleeve, the hook is not contacted with the rim when the piston is pulled upwards, and the rim can be prevented from being scratched when the hook is opened and closed.

The foregoing is a preferred embodiment of the present invention, and it should be noted that for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
