Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, a labor-saving cold storage door comprises a door body 1, a door lock 2, a handle 3 and a door frame 13, wherein a through slide way 10 is arranged inside the door lock 2, a slide rod 5 is movably sleeved inside the slide way 10, pistons are arranged at two ends of the slide rod 5, the slide rod 5 can move up and down inside the slide way 10, a latch is arranged on one side of the middle of the slide way 10, a clamping groove 14 is arranged on one side of the middle of the slide way 10, a gear 4 is fixedly sleeved on a rotating shaft of the handle 3 and is installed in the clamping groove 14, the gear 4 is meshed with the latch on one side of the slide rod 5, the gear 4 can rotate to drive the slide rod 5 to move upwards as long as the handle 3 is pressed, an upper sealing plate 11 is fixedly installed at the upper end of the slide way 10, and a sealed inner cavity i 6 is formed between the upper end of the slide rod 5 and the upper sealing plate 11. The inside of lock 2 is seted up with door frame 13 looks vertically sleeve 15, and sleeve 15 inboard is equipped with the pipeline and is linked together with the top of inner chamber I6, and the activity cup joints ejector pin 9 in sleeve 15, and ejector pin 9 can stretch out and draw back in sleeve 15, so long as slide bar 5 upwards moves, thereby the inside pressure of inner chamber I6 will pass through the pipeline and transmit to sleeve 15 inside and promote ejector pin 9 outwards ejecting, otherwise slide bar 5 downwards moves, and ejector pin 9 will inwards contract.

Wherein, the lower extreme fixed mounting of slide 10 has lower sealing plate 12, constitute sealed inner chamber II 7 between the lower extreme of slide bar 5 and the lower sealing plate 12, the slot 8 has been seted up to the door body 1 and door frame 13 contact part, the fixed joint in inside of slot 8 has hollow sealing strip, the sealing strip is close to the part of ejector pin 9 and is linked together with the bottom of inner chamber II 7, as long as the inside pressure of slide bar 5 upward movement inner chamber II 7 diminishes and forms the negative pressure, the sealing strip will shrink to the inside of slot 8, otherwise slide bar 5 downstream, the sealing strip will recover.

Wherein the handle 3 is extensible and the gear 4 can be rotated with a smaller force using the principle of leverage.

Wherein, the inner chamber I6 and the inner chamber II 7 and the inside of the sealing strip are filled with antifreeze, and the stability is good and the antifreeze can not be solidified.

Wherein, the contact surface of the sealing strip and the groove 8 is fixedly connected, and the sealing strip is contracted towards the inner direction of the groove 8.

The use method (working principle) of the invention is as follows:

firstly, a cold storage door is unlocked by a key, then a handle 3 is shifted downwards, a gear 4 rotates simultaneously when the handle 3 rotates, and the gear 4 is meshed with a sliding rod 5, so that the sliding rod 5 moves upwards, an inner cavity I6 is reduced, the internal pressure is increased, the pressure is transmitted to the inside of a sleeve 15 through a connecting pipe, a push rod 9 is pressed to outwards push against a door frame 13, the door is outwards pushed through reaction force, the door has inertia at the moment, and labor is saved during opening. The inner cavity II 7 is enlarged while the sliding rod 5 moves upwards, the internal pressure intensity is reduced, so that the anti-freezing liquid in the sealing strip flows to the inner cavity II 7, the volume of the sealing strip is reduced, the sealing strip is separated from the door frame 13 and is contracted into the groove 8, and a layer of protection is added to the sealing strip while the internal and external pressure intensities of the refrigeration house are balanced. When the handle 3 returns to the original point, the sliding rod 5 moves downwards, the internal pressure of the inner cavity I6 is reduced, the ejector rod 9 retracts into the door lock 2 at the moment, and the internal pressure of the inner cavity II 7 is increased, so that cooling liquid is filled in the sealing strip to expand the sealing strip.
