The side-by-side combination refrigerator provided by the embodiment of the invention comprises a turnover beam structure, wherein a trigger rod 3 of the turnover beam structure slides along the axial direction of a matching shaft 2 and then slightly rotates relative to the matching shaft 2, so that the lower end of the trigger rod 3 is matched with the lower end of the matching shaft 2, and a locking mechanism 4 is arranged between the lower end of the trigger rod 3 and the lower end of the matching shaft 2, so that the trigger rod 3 is locked relative to the matching shaft 2. Then, the turnover beam body 1 is rotatably connected with the matching shaft 2, the matching shaft 2 is fixedly connected with the door body, and the trigger rod 3 is arranged on the turnover beam body, so that when the trigger rod 3 is locked relative to the matching shaft 2, the turnover beam body 1 is locked relative to the door body. And because the locking mechanism 4 comprises a circumferential locking structure 41 and an axial locking structure 42, the circumferential locking structure 41 can prevent the trigger rod 3 and the matching shaft 2 from relatively rotating, and the axial locking structure 42 can prevent the trigger rod 3 and the matching shaft 2 from relatively displacing in the axial direction, when the locking mechanism 4 is in a locking state, the locking mechanism can prevent the turnover beam body 1 from rotating relative to the door body, and can also prevent the trigger rod 3 and the matching shaft 2 from relatively displacing in the axial direction. Compared with the prior art, the side-by-side combination refrigerator provided by the embodiment of the invention has the advantages that when the lower end of the trigger rod 3 is matched with the lower end of the matching shaft 2, even if a larger rotating torque force is applied to the side-by-side combination refrigerator, the contact surfaces of the trigger rod 3 and the matching shaft 2 generate a larger axial component force due to the draft angle, the lower end of the trigger rod 3 and the lower end of the matching shaft 2 are not separated, the locking function is not enabled to be invalid, and the locking effectiveness and reliability between the turnover beam 102 and the door body 101 are improved.
It should be noted that, the above-mentioned sliding of the trigger rod 3 along the axial direction of the mating shaft 2 means that the trigger rod 3 slides upwards or downwards along the axial direction of the mating shaft 2, and the sliding upwards or downwards is not specifically limited as long as the lower end of the trigger rod 3 can be mated with the lower end of the mating shaft 2, and the sliding upwards or downwards needs to be determined according to the specific structure of the lower end of the trigger rod 3 and the lower end of the mating shaft 2. The side by side refrigerator provided by this embodiment is to make the trigger rod 3 slide upwards along the axial direction of the matching shaft 2, so that the lower end of the trigger rod 3 is matched with the lower end of the matching shaft 2.
In order to realize that the triggering rod 3 is slidably connected to the turnover beam body 1 along the axial direction of the matching shaft 2, the embodiment provides a specific implementation manner, refer to fig. 7, specifically, the spring 5 is arranged on the turnover beam body 1 along the axial direction of the matching shaft 2, the turnover beam body 1 is provided with a first abutting part 51, the triggering rod 3 is provided with a second abutting part 52, the spring 5 is located between the first abutting part 51 and the second abutting part 52, therefore, the triggering rod 3 can slide up and down along the axial direction of the matching shaft 2 on the turnover beam body 1, the structure is simple and easy to implement, and the spring 5 is a common structure in life and has low price.
Further, referring to fig. 7, the side by side refrigerator according to the embodiment of the present invention further includes a trigger 6 for triggering the trigger rod 3 to slide up and down along the axial direction of the matching shaft 2, and the trigger 6 is connected to the upper end of the trigger rod 3. When the turnover beam structure 102 is installed on a refrigerator, a groove 7 is provided on a cabinet 100 of the refrigerator to be fitted with the trigger 6. When closing refrigerator door 101, trigger 6 gets into recess 7, and trigger 6 is extrudeed downwards by recess 7, drives trigger bar 3 and slides downwards, and the lower extreme of trigger bar 3 breaks away from with the lower extreme of cooperation axle 2 to make upset roof beam body 1 unblock for door body 101. Because the spring 5 is in a compressed state when the refrigerator door 101 is closed, when the refrigerator door 101 is opened, the trigger piece 6 is separated from the groove 7, the trigger rod 3 slides upwards under the action of the spring 5, and the lower end of the trigger rod 3 is matched with the lower end of the matching shaft 2, so that the turnover beam body 1 is locked relative to the door body 101. In particular, as shown in fig. 5, the trigger 6 may be provided as a slider 6.
In order to realize the function that the circumferential locking structure 41 can prevent the trigger rod 3 and the mating shaft 2 from rotating relatively and the function that the axial locking structure 42 can prevent the trigger rod 3 and the mating shaft 2 from displacing relatively in the axial direction, the embodiment provides a specific structure of the circumferential locking structure 41 and the axial locking structure 42:
referring to fig. 7 and 8, the lower end of the trigger rod 3 is provided with an annular stop cylinder 31, the annular stop cylinder 31 is located below the matching shaft 2 and is concentric with the matching shaft 2, and when the lower end of the trigger rod 3 is matched with the lower end of the matching shaft 2, the matching shaft 2 extends into the annular stop cylinder 31;
the circumferential locking structure 41 includes a first protrusion 411 and a first groove 412 that are fittingly disposed between an inner wall of the annular stopper tube 31 and an outer wall of the fitting shaft 2, the first groove 412 having a side wall 4121 extending in the axial direction of the fitting shaft 2;
the axial locking structure 42 includes a second projection 421 and a second groove 422 that are fittingly disposed between an inner wall of the annular stopper 31 and an outer wall of the fitting shaft 2, the second groove 422 having a side wall 4221 extending in the circumferential direction of the fitting shaft 2.
Referring to fig. 9 to 12, when the lower end of the trigger lever 3 is engaged with the lower end of the engagement shaft 2, the first protrusion 411 is engaged in the first groove 412, and since the first groove 412 has a sidewall 4121 extending in the axial direction of the engagement shaft 2, the first protrusion 411 is prevented from rotating around the circumferential direction of the engagement shaft 2, and thus the trigger lever 3 and the engagement shaft 2 are prevented from rotating relatively; when the lower end of the trigger rod 3 is engaged with the lower end of the engagement shaft 2, the second protrusion 421 is engaged in the second groove 422, and the second groove 422 has a sidewall 4221 extending along the circumferential direction of the engagement shaft 2, so that the first protrusion 411 can be prevented from moving along the axial direction of the engagement shaft 2, and the trigger rod 3 and the engagement shaft 2 can be prevented from axial relative displacement.
It should be noted that the first protrusion 411 may be disposed on any one of the inner wall of the annular stop cylinder 31 and the outer wall of the mating shaft 2, and the first groove 412 is disposed on the other one of the inner wall of the annular stop cylinder 31 and the outer wall of the mating shaft 2, that is, the first protrusion 411 is disposed on the inner wall of the annular stop cylinder 31 and the first groove 412 is disposed on the outer wall of the mating shaft 2, or the first protrusion 411 is disposed on the outer wall of the mating shaft 2 and the first groove 412 is disposed on the inner wall of the annular stop cylinder 31.
Specifically, the first protrusion 411 may be made of an elastic material, so that the first protrusion 411 may be clamped into the first groove 412 from the axial direction of the annular retaining tube 31, but because the first protrusion 411 is made of an elastic material, when the first protrusion 411 is clamped in the first groove 412, and the first protrusion 411 is subjected to a large rotation torque force around the circumferential direction of the mating shaft 2, the first protrusion 411 is easily elastically deformed, which easily causes the first protrusion 411 to be disengaged from the first groove 412, resulting in a failure of the locking function.
Further, in order to facilitate the first protrusion 411 to be caught in the first groove 412, the first groove 412 extends to the lower end surface of the mating shaft 2 in the axial direction of the mating shaft 2. This allows the first recess 412 to have an opening for the first protrusion 411 to enter, and when the first protrusion 411 is made of an inelastic material, the first protrusion 411 can enter the first recess 412 through the opening.
Referring to fig. 7, the second projection 421 is provided on a side wall of the first groove 412 extending in the axial direction of the fitting shaft 2, and the second groove 422 is provided on a side wall of the first projection 411 extending in the axial direction of the fitting shaft 2. This makes it possible to form the second protrusion 421 and the first groove 412 as an integral structure, and form the second groove 422 and the first protrusion 411 as an integral structure, so that the first protrusion 411, the first groove 412, the second protrusion 421 and the second groove 422 are relatively simple and convenient to manufacture.
Further, the first protrusions 411 and the first grooves 412 are each provided in plurality in one-to-one correspondence along the circumferential direction of the mating shaft 2. Therefore, the reliability and stability of circumferential locking between the trigger rod 3 and the matching shaft 2 are improved through the cooperation of the first protrusions 411 and the first grooves 412, and further the reliability and stability of circumferential locking between the turnover beam body 1 and the door body 101 are improved.
Further, the second protrusions 421 and the second grooves 422 are provided in a plurality in a one-to-one correspondence along the axial direction of the mating shaft 2. Therefore, the reliability and stability of axial locking between the trigger rod 3 and the matching shaft 2 are improved through the cooperation of the second protrusions 421 and the second grooves 422, and further the reliability and stability of axial locking between the turnover beam body 1 and the door body 101 are improved.
Preferably, as shown in fig. 8, the first protrusion 411 and the first groove 412 are fan-shaped structures. Therefore, when the inner wall of the annular stop cylinder 31 is provided with the first protrusion 411 and the outer wall of the matching shaft 2 is provided with the first groove 412, the inner hole section of the annular stop cylinder 31 and the cross section of the matching shaft 2 are circular, so that the first protrusion 411 and the first groove 412 are arranged to be fan-shaped structures, the first protrusion 411 and the first groove 412 are firmly clamped, and the first protrusion 411 and the first groove 412 are simple and convenient to manufacture. In practical applications, the arc length of the fan-shaped structure is generally set to be a quarter of a circle, but the embodiment of the present invention is not limited thereto.
Preferably, as shown in fig. 8, the second protrusions 421 and the second grooves 422 are both bar-shaped structures. Therefore, when the second protrusion 421 is disposed on the side wall of the first groove 412 extending along the axial direction of the mating shaft 2 and the second groove 422 is disposed on the side wall of the first protrusion 411 extending along the axial direction of the mating shaft 2, since the side walls of the first groove 412 and the first protrusion 411 extending along the axial direction of the mating shaft 2 are planes, the second protrusion 421 and the second groove 422 are both disposed in a bar structure, so that not only the second protrusion 421 and the second groove 422 are firmly engaged, but also the second protrusion 421 and the second groove 422 are simple and convenient to manufacture. In practical applications, the length of the strip-shaped structure is generally set to be equal to the width of the sidewall of the first groove 412 extending along the axial direction of the mating shaft 2, but the embodiment of the present invention is not limited thereto.
Further, referring to fig. 13, a positioning hole 21 is formed in the axis of the engaging shaft 2, and a positioning post 22 is formed on the annular cylinder 31 corresponding to the positioning hole.
