Description

Tray locking mechanism locked by deadlock

Technical Field

The utility model relates to an incubator structure field especially relates to an utilize deadlock to carry out tray locking mechanism who locks.

Background

Incubator tray installs in the incubator, and similar drawer can be taken out in the incubator for cooperation anchor clamps hold the laboratory ware, and current incubator tray commonly used is screwed or the hasp is fixed through the knob, when using, needs the unblock earlier, pulls out the tray again, and when locking, the tray needs to be pushed into earlier, locks again, and complex operation can not one step put in place, needs have twice operation flow.

Chinese patent publication No. CN216024934U, publication No. 2022, 3 months and 15 days, discloses an incubator tray locking mechanism, comprising: the tray is arranged on the bracket, the locking mechanism is used for locking and unlocking the tray and the bracket, and the locking mechanism is also used as a handle to pull out the tray; the locking mechanism is composed of: the tray comprises a main handle, a buckling plate, a handle fixing seat and a lock catch, wherein the handle fixing seat is fixedly arranged on the tray, the main handle is rotatably connected with the handle fixing seat, the buckling plate is fixedly arranged on the tray, an opening used for matching with the lock catch is formed in the buckling plate, and the rotation of the main handle is used for enabling the lock catch to be buckled with the buckling plate; an auxiliary handle used for limiting the rotation of the main handle is arranged in the main handle; when the tray is unlocked, the main handle and the auxiliary handle are held simultaneously, the main handle and the auxiliary handle are drawn close, at the moment, the buckle on the auxiliary handle is separated from the clamping groove in the handle fixing seat, at the moment, the main handle can rotate freely, and after the main handle rotates, the buckle is separated from the fastening plate.

Although the tray locking mechanism of the incubator is more convenient and fast in operation, the tray locking mechanism still has two separated operation flows, and the auxiliary handle of the tray locking mechanism is not flexible frequently, tests the hand force and the spring resetting capability of a user, and is unreliable in locking.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model relates to an utilize the deadlock to carry out tray locking mechanism who locks.

The utility model adopts the following technical scheme:

a tray locking mechanism locked by deadlock comprises a movable handle main body, a movable handle base, a movable handle bottom lock, a movable handle connecting rod and a movable handle pressing block, wherein the movable handle base is fixedly connected to a tray;

after the movable handle main body is vertically turned, the movable handle main body rotates to drive the movable handle connecting rod to turn, the movable handle connecting rod drives the movable handle pressing block to turn, and the movable handle pressing block is turned into a locking groove of the movable handle bottom lock to lock the movable handle bottom lock by utilizing the principle of a four-bar dead point mechanism;

after the movable handle main body is horizontally turned, the movable handle main body rotates to drive the movable handle connecting rod to turn, and the movable handle connecting rod drives the movable handle pressing block to turn, so that the movable handle pressing block turns out of a lock groove of the movable handle bottom lock to be unlocked.

Preferably, the movable handle main body is divided into a movable handle main body A and a movable handle main body B, two ends of the movable handle main body A are respectively and fixedly connected with the movable handle main body B, and the movable handle base and the movable handle connecting rod are respectively hinged to the movable handle main body B through pin shafts at two positions at intervals.

Preferably, the two sides of the movable handle base are fixedly connected with positioning seats, guide grooves are correspondingly formed in the movable handle bottom lock, and the positioning seats are matched with the guide grooves.

Preferably, the movable handle main body a and the movable handle main body B are integrally fixed and formed.

Preferably, the movable handle body a is a round bar.

The beneficial effects of the utility model are that: (1) The utility model designs a novel mode completely different from the traditional incubator tray locking mechanism, and the novel mode utilizes the four-bar dead point mechanism principle to lock, so that the problem of unreliable locking can be effectively solved; (2) The utility model discloses only realize locking and unblock through the process of a rotatory activity handle main part, the action is succinct effective, targets in place in one step.

Drawings

Fig. 1 is a front view of the present invention;

fig. 2 is a perspective view of the present invention;

fig. 3 is a schematic structural view of the dead lock state of the present invention;

in the figure: 1. the movable handle comprises a movable handle main body A,2, a movable handle main body B,3, a movable handle base, 4, a movable handle bottom lock, 5, a movable handle connecting rod, 6, a movable handle pressing block, 7, a positioning seat, 8 and a tray.

Detailed Description

The technical solution of the present invention is further described in detail by the following specific embodiments in combination with the accompanying drawings:

example (b): as shown in the attached figure 1, the tray locking mechanism locked by using deadlock comprises a movable handle main body, a movable handle base 3, a movable handle bottom lock 4, a movable handle connecting rod 5 and a movable handle pressing block 6, wherein the movable handle base is fixedly connected to a tray 8;

as shown in fig. 3, after the movable handle main body is vertically turned, the movable handle main body rotates to drive the movable handle connecting rod to turn, the movable handle connecting rod drives the movable handle pressing block to turn, so that the movable handle pressing block is turned into a lock groove of the movable handle bottom lock to lock the movable handle bottom lock by utilizing the principle of a four-bar dead point mechanism;

as shown in fig. 2, after the movable handle main body is horizontally turned, the movable handle main body rotates to drive the movable handle connecting rod to turn, and the movable handle connecting rod drives the movable handle pressing block to turn, so that the movable handle pressing block turns out of the lock groove of the movable handle bottom lock to unlock.

The movable handle main body is divided into a movable handle main body A1 and a movable handle main body B2, two ends of the movable handle main body A are respectively and fixedly connected with the movable handle main body B, and two positions at intervals on the movable handle main body B are respectively hinged with a movable handle base and a movable handle connecting rod through pin shafts. The movable handle main body A and the movable handle main body B are integrally fixed and formed. The movable handle main body A is a round rod.

The two sides of the movable handle base are fixedly connected with positioning seats 7, guide grooves are correspondingly arranged on the movable handle bottom lock, and the positioning seats are matched with the guide grooves.

When this utilize deadlock to carry out tray locking mechanism of locking uses, promote tray to the incubator in through activity handle main part, the positioning seat on the activity handle base corresponds the guide way that inserts on the activity handle end lock this moment, vertical upset activity handle main part, and activity handle main part rotates and drives the upset of activity handle connecting rod, and activity handle connecting rod drives the upset of activity handle briquetting, makes the activity handle briquetting overturn to the locked groove of activity handle end lock and utilizes four connecting rod dead point mechanism principle locking activity handle end lock.

During unlocking, the movable handle main body is horizontally overturned, the movable handle main body rotates to drive the movable handle connecting rod to overturn, and the movable handle connecting rod drives the movable handle pressing block to overturn, so that the movable handle pressing block is overturned out of a lock groove of the movable handle bottom lock to be unlocked.
