Description
Affiliated technical field
The utility model relates to a kind of injection machine safety door positioner.
Background technology
Traditional injection machine safety door leans against on the guide rail to be installed a projection and blocks wheel and retreat and locate; Wheel must be crossed from projection when opening the door, and needs big pulling force, uses inconveniently, and retreats automatically easily during the door vibrations and crosses projection, brings potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model provides the injection machine safety door positioner that a kind of switch door is easy and convenient, mistake is opened, security reliability is high automatically when eliminating the safety door vibrations.
The utility model solves the technical scheme that its technical problem adopts: a kind of injection machine safety door positioner, and it comprises hook, spring, handle push rod and limited block; Be provided with one around axle in the middle of the described hook, tail end is provided with a spring, and front end is provided with a downward hook corresponding with the shape of backstay, and the front portion is provided with a projection that links with the handle push rod; The upper end of described handle push rod is provided with one around axle, and its lower end is positioned at by the top of the anterior projection of described hook; Described limited block and described backstay are positioned at same horizontal level.
Described hook is by being installed on the safety door around axle in the middle of linking up with; The tail end of described spring one termination hook, the other end is installed on the safety door; Described handle push rod is installed on the safety door around axle by handle push rod upper end; Described limited block is fixed on the safety door; Described backstay is installed on the injection molding machine.
The beneficial effects of the utility model: injection machine safety door positioner utilization hook of the present utility model hooks the fixed object location under the spring force effect, and utilize the interlock of handle push rod to open hook and remove the location, not only switch is easy and convenient, and staff not during the fixed handle push rod of position vibrations can't overcome spring tension and open hook, eliminated safety door fully and opened automatically by mistake, safe possibility strengthens.
Below in conjunction with the drawings and specific embodiments the utility model is described.

The specific embodiment
As shown in Figure 1, a kind of injection machine safety door positioner, it comprises hook 1, spring 2, handle push rod 3, limited block 4 and backstay 5; Be provided with one around axle 11 in the middle of the described hook 1, tail end is connected with a spring 2, and front end is provided with the hook groove 51 corresponding downward hooks 12 with backstay 5, and the front portion is provided with a projection 13 that links with handle push rod 3; The upper end of described handle push rod 3 is provided with one around axle 31, and its lower end is positioned at by the top of described hook 1 anterior projection 13; Described limited block 4 is positioned at same horizontal level with described backstay 5.
Described hook 1 is by being installed on the injection machine safety door 6 around axle 11 in the middle of it; The tail end of described spring 2 one terminations hook 1, the other end is installed on the safety door 6; Described handle push rod 3 is installed on the safety door 6 around axle 31 by its upper end; Described limited block 4 is fixed on the safety door 6; Described backstay 5 is installed on the injection molding machine.
Operation principle: as shown in Figure 2, the utility model is in the motion intermediateness, when at closing time, holds handle push rod 3 right sides and draws, and the hook 12 of linking up with 1 front end moves to backstay 5 directions with safety door 6.As shown in Figure 3, during the location, hook 1 under spring 2 pulling force effects in the middle of it around axle 11, have clockwise revolving force, and hook backstay 5 hook groove 51, safety door can not arbitrarily be opened.As shown in Figure 4, when opening the door, hold handle push rod 3 Zolas, handle push rod 3 being rotated in a clockwise direction around axle 31 on it promotes hook 1 rotating around axle 11 inhours in the middle of it, thereby unclamps the backstay that hooks 5, and safety door can easily be opened.
