Abstract

The utility model relates to a gate driving machine. A multiple section type displacement gear is arranged in a gear box and can axially move between a driving gear and a motor gear to control whether the motor gear is linked with the driving gear or not, and in addition, the gear box is provided with a rotary shaft which is pivoted with a shifting fork, so that the shifting fork is sheathed on the displacement gear. The axial movement of the displacement gear is controlled by a shifting rod connected with a wrench and arranged on the rotary shaft to determine whether the motor gear is moved with the driving gear or not, and the gate is opened by electricity or by hand smoothly and conveniently.

Description

Gate driving machine

The utility model relates to a kind of gate driver, You Zhiqi can be easily with the engaging tooth crop rotation displacement of gear-box and for the manpower person that can pass the gate effortlessly.

At present relatively large dwelling house or factory all generally adopt comparatively abundant track to pass the iron gate of formula, and the gate of therefore planting pattern is very heavy, so it is general all with the driving force of electronic gate driver as this kind of keying gate, yet each change-speed gearing of the motor gear warp in the gate driver of tradition and travelling gear all are fixedly to put form to mesh, be when can't open and close the gate with electric power, also the manpower promotion can be hindered waste time and energy because of travelling gear and other gears still remain on engagement when the power failure situation takes place.

Therefore, the main purpose of the utility model is to provide a kind of gate driver, in its gear-box, be provided with shifted gear that a speed change uses and be and can dead man control it and between motor gear and drive, move and make the motion or separate of being engaged with each other, electric power or manpower are driven all can accomplish simple and easy operation.

Other purposes of the utility model and function will cooperate following accompanying drawing further to illustrate; only the following stated person only is in order to explain the utility model preferred embodiment; not being that attempt is done any formal restriction to the utility model according to this, is to have any modification or change at the following relevant the utility model of being done of identical spirit all must be included in the category that the utility model is intended to protection with all.

Brief description:

Fig. 1 is the three-dimensional cutaway view of the utility model detailed structure;

Fig. 2 is the planar gesture figure of the shifted gear of the utility model when breaking away from travelling gear; And

Planar gesture figure when Fig. 3 is the shifted gear engaged transmission gear of the utility model.

At first as shown in Figure 1, the gate driver of the utility model mainly is to provide power to be gone out by the power transmission shaft transferring power of the concentric of travelling gear 4 after the gear-box speed change to open and close the gate by motor 2 again, because the mechanism at the driving gate after this power transmission shaft is known structure, so will not give unnecessary details; The principal character of the utility model lies in the shifted gear 3 that is provided with a two-section between motor gear 21 and the travelling gear 4, meshing with motor gear 21 for system of this shifted gear 3 than large diameter gear, than the path gear then is to supply and driving cog crop rotation engagement, and its centre bore is to be to be located at one so that can move axially with being slidingly matched; Be provided with rotatable rotating shaft 1 in gear-box in addition, the one end extends gear-box and is provided with dead man 11 outward, extend the interior rotating shaft appropriate location of gear-box and then extended an extension rod 12, and in the be pivoted fork 13 of a tool fork groove 131 of extension rod 12, make fork groove cover be sandwiched in shifted gear 3 sides, can make when mat is pulled dead man 11 extension rod 12 do swing and with seasonal fork 13 do shifted gear 3 axially displaced and can break away from travelling gear 4 or with its engagement (as Fig. 2, shown in 3), make when meeting with the power failure situation, as long as shifted gear 3 is pulled away with the engagement of travelling gear 4 and can not waste muscle power at all easily with manpower promotion gate, time.

By the above as can be known, the structure practicality of the utility model, have and promote the effect part, and do not have the product of same structure to be disclosed in elder generation, therefore fully met the regulation of utility model patent, now file an application in accordance with the law, please give patent for expecting.

The figure number part:

1 rotating shaft, 2 motors

11 dead mans, 21 motor gears

12 extension rods, 3 shifted gears

13 forks, 4 travelling gears

131 fork grooves

Claims

1, a kind of gate driver lies in and is provided with motor gear that is incorporated into motor and the travelling gear that is incorporated into power transmission shaft in the gear-box, it is characterized in that:

In between motor gear and travelling gear, be provided with the shifted gear that can move axially of a multisection type, its each section of mat can mesh with motor gear and travelling gear respectively after moving or break away from, be provided with a rotating shaft in gear-box in addition, this rotating shaft one end extends outer and is provided with dead man, be provided with an extension rod and extend interior appropriate location, and be pivoted with the fork of tool fork groove in extension rod, this fork groove cover is sandwiched between carrier wheel move and does clutch, make under the power failure situation and also can promote the gate easily with manpower.
