Description

Fast quick-detach seat

Technical field:

The utility model belongs to the auto parts and components field.

Background technology:

Folding or detouchable seat in the present self-propelled vehicle need be equipped with the seat lock that has with self-propelled vehicle floor latch functions by functional requirement.And the seat floor latch of matching at polytype self-propelled vehicle at present mostly is the latch hook formula, and requires to install on automotive floor panel the U-shaped hook that is projected on the floor level.At present this type of latch hook formula seat lock exists following weakness: 1. its structure relative complex of latch hook formula seat lock.2. the reliability of locking power and locking is relatively poor relatively.3. caused the closely cooperating property of seat locking relatively poor owing to protrude from the position deviation of the hook of U-shaped on the floor, then required the raising of the parts accuracy of manufacture that is associated for guaranteeing closely cooperating property, thus the raising that has brought cost.4. equally owing to protrude in the installation of the U-shaped hook of automotive floor panel, destroy the planeness of car bottom plate, influenced the in-use performance in its space.5. there is welded structure in latch hook formula seat lock, and production tolerance's precision is uncontrollable.

Summary of the invention:

In order to solve the shortcoming that existing seat lock exists, the utility model provides a kind of fast quick-detach seat of axis hole locking mode.

The utility model comprises the support beam of automotive seat lower end, support beam is connected with support on the seat lock, wherein the concrete structure of seat lock is: the mandrel spring is inserted in the anchor shaft in the core sleeve, anchor shaft is fixed by jam nut and support, mandrel passes jam nut and the release connecting panel is installed, and axle sleeve is enclosed within on the anchor shaft, and fixes by the stop collar that is riveted on the support, on anchor shaft, be with the anchor shaft spring, in the groove of anchor shaft, ball be installed; On the connecting panel on the support beam, hook is installed.

The utility model belongs to the parts that automobile is used, it is a kind of collapsible and safety chair seats of car with fast assembling-disassembling function, adopt the blocking device of shaft hole mode structure on the seat, have simple in structure, cost is low, the reliable fast assembling-disassembling of locking and characteristics such as safe and reliable, is specially adapted to high-mobility, multipurpose, wheeled vehicle, multi-functional vapour car is selected for use.

Automotive seat of the present utility model, structure comprise pedestal, backrest, recliner, reach seat fast assembling-disassembling safe locking device.Finish the turnover of seat by recliner, and seat dismounting blocking device is a function conveniently when being used for guaranteeing after the chair mounted the reliable and dismounting of locking.
