Description

201225881 VI. Description of the Invention: [Technical Field] The present invention relates to a pull-and-synchronization device for a side-traveling slide rail, and more particularly to a device mounted on both sides of a pull-out carrier and located at a pull-out carrier A pull-and-synchronization device that moves between the cabinets and moves the two sides of the pull-out carrier during the pulling process. [Prior Art] The slide rails generally used for the steel ball structure on the pull-out carrier can be divided into two types: the side walk type is disposed on the side sides of the pull-out bearing member, and the sitting type is disposed on the bottom sides of the pull-out bearing member. 'The two are similar in the structure of the rails covering each other, and there is a difference in the direction of the gap formed by the coating when the two are fixed in the cabinet. The slide rail has a plurality of rails that are sleeved with each other and are mutually slidable, and a plurality of steel balls that are rolled between the panels. The rails can be roughly divided into outer rails and inner rails due to the position of the sleeves. When the rails are pulled out and fully extended, the yaw caused by the gap between the inner and outer rail planes is the most serious, and the slipping steel balls The direction of the corresponding ends of the inner and outer sides is the most stable. That is, when the cabinet body is locked, the vertical direction of the side-traveling slide rails is the most stable in the vertical direction, so that the heavy-duty storage parts such as the storage tool and the folding tool holder can be carried. However, the left and right yaw is mainly from the gap between the inner and outer rail planes, and the rails that can be slipped by the double-side sliding can not enter and exit the cabinet synchronously on both sides, so that the pulling carrier after the load is left to the right. The left side enters the right side, and the two continuous actions are the shaking of the pulling carrier. And the yaw direction is the direction of the gap in which the rails are covered with each other. Therefore, the severe swaying of the 201225881 will cause the outer sleeve of the outer sleeve to be tapered and the rail will collapse. When the walking type slide rails are walking all the way, the left and right yaws are the most stable, mainly from the mutual cooperation between the two ends of the rails and the sliding steel balls, but the vertical direction of the load and the rails are mutually sheathed. The notch and the plane gap are in the same vertical direction. Therefore, when the load is pulled, the pull-out carrier is pulled out and fully collapsed. If the load exceeds the load, the mutually-arranged rails will collapse. The side-sliding slippery load t, the manufacturing cost is low, the market share is high, and the left yaw is severely ‘the pull-out carrier is pulled out of the cabinet rail. The walking type slide rail is not resistant to the load. The manufacturing cost is high. The market share is low, and it is not easy to be biased. When the pulling bearing member is pulled away from the body, the rail piece is hidden. Therefore, in order to solve the shortcomings of the market's high-occupancy side-sliding rails, the movable rails that are forcibly fixed on both sides of the pulling carrier must be synchronized into and out of the cabinet during the drawing stroke. The reason why the market share of the pull-out carrier is not high and the market share is high, which is derived from the low unit price. Therefore, when adding the functional structure of the maintenance device such as the gear and the external gear, it is necessary to consider the overall cost structure. The overall cost structure of the maintenance device includes the number of components, the number of components in the plant, the number of operations in the plant, the multi-stakes in the field, and the accuracy required for assembly. The conventional external maintenance device has the above-mentioned shortcomings, and under the premise of reducing the cost, it must also take into account the integrity of the function, and even in the conventional technology to reduce the cost, it is supported by the hook piece. Continuous toothing, 201225881 causes the continuous toothing to have an upper and lower elastic displacement space. When the wide pulling carrier is pulled out from the most intermediate position, the gear will travel heavily in one-way deflection to the continuous toothing' to produce continuous toothing. In the state with elastic displacement space, it is forced to pull off the gear, causing double-sided irregular jumping. In the patent case of the Chinese patent CN101221008A, in order to support the continuous tooth portion and the sleeve side slide rail, and then lock the (10) plate, the exercise can cover the side slide rail and generate - support the guide tooth The above-described technique not only increases the combined components and assembly process, but also increases the overall cost. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a pull-synchronization device that is simple in construction, easy to assemble, and low in manufacturing cost.
