Referring to fig. 1 and 2, through a study of a related art supporting and sliding structure, a related art roller 5 and a supporting leg are separated and located at front and rear positions of a refrigerator 7, respectively. When the refrigerator 7 is moved, the two rollers 5 at the back of the refrigerator 7 roll on the ground 9, and the two adjusting feet 8 at the front slide on the ground 9. When the adjusting foot 8 slides on the ground 9, sliding friction is generated between the adjusting foot 8 and the ground 9, and the sliding friction can generate large friction force between the adjusting foot 8 and the ground 9, so that the ground 9 is easily scratched. In order to solve the problem that the ground 9 is scratched and the refrigerator 7 is moved, the following scheme is adopted for solving the problem.
As shown in fig. 3 to 5 and 12 to 14, the frame structure provided by the present embodiment includes a lower beam 6, a fixing assembly 1, a supporting member 2, a first height-adjusting structure and a second height-adjusting structure;
the bottom end of the fixed component 1 is movably provided with a roller 5;
the first height-adjusting structure is arranged on at least one of the top of the fixed assembly 1 and the lower beam 6, the fixed assembly 1 is movably connected with the lower beam 6 through the first height-adjusting structure, and the first height-adjusting structure is used for adjusting the distance between the fixed assembly 1 and the lower beam 6;
at least one of the supporting piece 2 and the fixing component 1 is provided with the second height-adjusting structure, the supporting piece 2 is movably connected with the fixing component 1 through the second height-adjusting structure, and the second height-adjusting structure is used for adjusting the distance between the supporting piece 2 and the lower beam 6;
in a part of the adjusting stroke of the second height-adjusting structure, the bottom end of the support member 2 is higher than or equal to the bottom end of the roller 5; in another part of the adjustment stroke of the second height-adjusting structure, the bottom end of the support member 2 is lower than the bottom end of the roller 5.
From the above, the frame structure includes the lower beam 6, the fixing component 1 and the supporting component 2, and the first height-adjusting structure and the second height-adjusting structure are matched with the fixing component 1 and the supporting component 2, so that the sliding function and the supporting function can be switched in the frame structure. When the function is switched to the sliding function, the refrigerator can move relative to the floor 9 through rolling friction, and when the function is switched to the supporting function, the refrigerator 7 can be stably supported and the height adjusting effect in a wide range can be achieved. Through the different states of sliding function and support function, alright with the pertinence remove refrigerator 7 and support the operation, improve the convenience that refrigerator 7 removed, avoid fish tail ground 9.
As shown in fig. 3 and 4 in combination with fig. 12-14, the top of the fixed component 1 is movably connected to the bottom of the lower beam 6 through the first height-adjusting structure, and the relative position between the fixed component 1 and the lower beam 6 can be adjusted by the first height-adjusting structure, so that the distance between the fixed component 1 and the lower beam 6 can be adjusted through the relative movement between the fixed component 1 and the lower beam 6. When the refrigerator 7 is placed on the floor 9, the distance between the fixing assembly 1 and the lower beam 6 can be converted into an adjustment of the height of the refrigerator 7.
Meanwhile, the supporting piece 2 can be movably connected with the fixed component 1 through the second height-adjusting structure, so that the supporting piece 2 and the fixed component 1 can move relatively through adjustment of the second height-adjusting structure, and the supporting piece 2 is close to or far away from the lower beam 6 through adjustment of the second height-adjusting structure. In the process that the supporting piece 2 is close to or far away from the lower beam 6, the sliding function and the supporting function of the frame structure can be switched, and the switching of the two functions can be divided into two states, specifically as follows:
in the first condition, i.e. during a part of the adjustment stroke of the second height-adjustment structure, the bottom end of the support 2 can be adjusted to be higher than or equal to the bottom end of the roller 5. As shown in fig. 12, the supporting member 2 is adjusted relative to the fixing assembly 1 by a second height-adjusting structure, when the bottom end of the supporting member 2 is adjusted to be higher than the bottom end of the roller 5, the supporting member 2 is higher than the roller 5 and is in a suspended state, and the roller 5 is lower than the supporting member 2 and is in a state of contacting with the ground 9. Alternatively, when the bottom end of the supporting member 2 is adjusted to be equal to the bottom end of the roller 5, the supporting member 2 and the roller 5 are simultaneously in contact with the ground 9. In this state, the sliding function is switched to the frame structure, and the roller 5 can contact the floor 9 and form rolling friction with the floor, thereby facilitating the movement of the refrigerator 7.
In a second condition, i.e. in another part of the adjustment travel of the second raising structure, the bottom end of the support 2 can be adjusted to be lower than the bottom end of the roller 5. As shown in fig. 13 and 14, when the bottom end of the supporting member 2 is adjusted to be lower than the bottom end of the roller 5, the supporting member 2 is lower than the roller 5 and in a state of contacting with the ground 9, and the roller 5 is higher than the supporting member 2 and in a suspended state, the supporting member 2 is adjusted relative to the fixing assembly 1 by the second height-adjusting structure. In this state, the support function is switched to the support function of the frame structure, and the support member 2 can be in contact with the floor 9 and in a support state with the floor, so that the refrigerator 7 can be placed more stably.
In the second state, as shown in fig. 14, the frame structure is switched to the state of the supporting function, and the fixing assembly 1 is adjusted by matching with the first height-adjusting structure, so that the fixing assembly 1 is close to or away from the lower beam 6, and the height of the refrigerator 7 can be adjusted. For example, the refrigerator 7 is normally placed on the floor 9, and when the fixing member 1 is close to the lower beam 6, the refrigerator 7 can be lowered, and when the fixing member 1 is far from the lower beam 6, the refrigerator 7 can be raised.
The first height-adjusting structure may adopt a mechanical structure including a first thread height-adjusting structure 3, a first rail height-adjusting structure, a first sliding rail height-adjusting structure, a first hydraulic height-adjusting structure or a first pneumatic height-adjusting structure. First screw thread height-adjusting structure 3 can be as shown in fig. 3 or fig. 4, and card rail height-adjusting structure can adopt draw-in groove and elasticity fastener looks slip joint complex structure, and slide rail height-adjusting structure can adopt slider and slide rail looks slip fit's structure, perhaps adopts the hydraulic pressure height-adjusting structure that hydraulic pressure technique constitutes and the atmospheric pressure height-adjusting structure that adopts atmospheric pressure technique to constitute, as long as can make fixed subassembly 1 for 7 rectilinear movement of refrigerator and adjust relative distance's relevant structure can. Those skilled in the art can select a suitable height adjustment structure in consideration of various aspects such as usage scenarios and costs, and details thereof are omitted here.
Similarly, the second height-adjusting structure may include a second thread height-adjusting structure 4, a second rail height-adjusting structure, a second hydraulic height-adjusting structure, or a second pneumatic height-adjusting structure. Specific types of structures can be found in the above description of the first height adjustment structure. Moreover, in the above-mentioned mechanical structures of the first height-adjusting structure and the second height-adjusting structure or equivalent mechanical structures, any combination may be selected and assembled, which is not described herein again.
Preferably, the first thread height-adjusting structure 3 comprises a first external thread located at the top of the fixing assembly 1 and a threaded hole located at the lower beam 6, and the first external thread is in threaded connection with the threaded hole.
The first thread height-adjusting structure 3 can movably connect the fixed component 1 and the lower beam 6 in a threaded connection mode so as to adjust the distance between the fixed component 1 and the lower beam 6 in a threaded screwing mode.
As shown in fig. 3 to 5, a first external thread is provided on the top of the fixing member 1, and a threaded hole is provided on the lower beam 6 to be engaged with the first external thread. So that the fixing component 1 can be screwed relatively to the thread hole on the lower beam 6 through the first external thread to adjust the distance between the first external thread and the thread hole. The first external thread and the threaded hole on the lower beam 6 together form the first thread heightening structure 3.
Similarly, a threaded hole may be formed in the top of the fixing assembly 1, and a threaded structure, such as a screw, may be disposed on the lower beam 6. So that the fixing component 1 can be screwed relatively to the thread through the thread hole and the thread structure on the lower beam 6 to adjust the distance between the two. In this case, the threaded bore is part of the first thread elevation 3 and, together with the thread on the lower beam 6, forms the first thread elevation 3.
Further, the top of the fixing component 1 is also provided with a limiting part 11; when the fixing component 1 is close to the lower beam 6, the limiting part 11 is abutted against the lower beam 6.
As shown in fig. 4, the stopper portion 11 is located at the top of the fixing member 1, and moves closer to the fixing member 1 with respect to the lower beam 6 and moves farther from the fixing member 1 with respect to the lower beam 6. In the process, when the fixing component 1 approaches the lower beam 6, the limiting part 11 can abut against the bottom of the lower beam 6, so that the top of the fixing component 1 and the lower beam 6 are in contact and support in advance through the limiting part 11, and a certain gap is formed between the top of the fixing component 1 and the lower beam 6. When the refrigerator 7 is placed on the ground 9, the fixing component 1 can stably support the preset refrigerator 7 by contacting the lower beam 6 through the limiting part 11; the space formed between the fixing member 1 and the lower beam 6 by the stopper portion 11 can make the operable space secured to the bottom of the refrigerator 7 larger.
Therefore, the fixing assembly 1 is in contact with the lower beam 6 through the limiting part 11 under the same operation space, and can be used for stably supporting the preset refrigerator 7, and the whole weight is not applied to the first heightening structure. For example, when the first height-adjusting structure adopts the first thread height-adjusting structure 3, the weight of the refrigerator 7 can be prevented from being applied to the associated thread structure of the first thread height-adjusting structure 3, so that the service life of the first height-adjusting structure and the stability of the placement of the refrigerator 7 are ensured.
Further, the cross section of the limiting part 11 includes a complete annular structure or a discontinuous annular structure, and the annular structure is sleeved on the periphery of the first thread height-adjusting structure 3.
As shown in fig. 3 to 7, the cross section of the limiting portion 11 is an annular structure. Spacing portion 11 of loop configuration can evenly form the support with the bottom of underbeam 6 in the circumference of fixed subassembly 1 and underbeam 6 hookup location, makes the even atress of fixed subassembly 1, improves the stability that refrigerator 7 put.
In particular, a complete ring structure or an interrupted ring structure may be used. The complete annular structure has the advantage of good stress effect, and the discontinuous annular structure has the advantage of material saving.
Preferably, the supporting member 2 is a cylinder 21, an inner thread is arranged on the inner wall of the cylinder 21, and a second outer thread matched with the fixing component 1 is arranged on the fixing component 1; the cylinder body 21 is sleeved on the peripheries of the fixed component 1 and the roller 5 and movably sleeved with the fixed component 1 through the internal thread and the second external thread; the internal thread and the second external thread constitute the second height-adjusting structure.
As shown in fig. 3 to 5, the cylinder 21 can be engaged with the second external thread of the external surface of the fixing member 1 through the internal thread of the internal wall thereof, so that the cylinder 21 can be operated by rotating relative to the fixing member 1 to adjust the distance between the cylinder and the lower beam 6.
Therefore, when the frame structure needs to be switched to the state of the sliding function, the supporting member 2 can be rotated relative to the fixing assembly 1, so that the supporting member 2 is close to the lower beam 6, and the roller 5 accommodated in the inner hole of the cylinder 21 is exposed, so that the roller 5 is lower than the supporting member 2. Similarly, when the frame structure needs to be switched to the state of the supporting function, the supporting member 2 can be rotated relative to the fixing component 1, so that the supporting member 2 is far away from the bottom of the preset refrigerator 7, and the roller 5 is accommodated into the inner hole of the cylinder 21, so that the roller 5 is higher than the supporting member 2. It should be noted that, the height explained at this time is relative to the direction in which the refrigerator 7 is placed in normal use, and the directions shown in fig. 12 to 14 may be referred to.
The shape structure of the outer wall of the cylinder 21 may include a cylindrical structure and a prismatic structure. Meanwhile, if the rotation operation of the cylinder 21 is facilitated, an anti-slip structure such as an anti-slip sleeve and anti-slip lines can be arranged on the outer wall of the cylinder 21. The anti-slip structure of the outer wall of the cylinder 21 and the shape structure of the outer wall of the cylinder 21 together form an external structure easy for rotation operation. The outer structure of the cylinder 21 is not limited herein.
Further, the bottom of the cylinder 21 extends inward in the radial direction from the inner wall to form a support portion 211 of the support 2. As shown in fig. 8, the supporting portion 211 is formed by protruding and extending from the inner wall of the bottom of the through hole and extending inward along the radial direction of the through hole, and the bottom end surface of the supporting portion 211 is formed to belong to the bottom end surface of the cylinder 21, or to be said to belong to a plane with the bottom end surface of the cylinder 21, thereby increasing the area of the bottom end surface of the cylinder 21, increasing the contact area when the bottom end surface of the cylinder 21 contacts the ground 9, and reducing the pressure on the ground 9.
It should be noted that, although the supporting portion 211 is formed at the bottom portion of the inner wall of the through hole and extends inward along the radial direction of the through hole, this is only a limitation to the structure thereof, and in terms of the connection manner, the supporting portion 211 and the cylinder 21 may be integrated or may be detachable.
Further, the supporting portion 211 includes a complete ring structure or an interrupted ring structure. As shown in fig. 9 to 11, the supporting portion 211 may extend inward uniformly along a circumference of the inner wall of the inner hole of the cylinder 21 to form a complete ring structure; or only a portion of the inner wall of the bore of the barrel 21 may extend inwardly to form an interrupted annular configuration. In fig. 9, it can be seen that the inner wall of the through hole extends uniformly inward around the circumference, and the support portion 211 forms a complete ring structure. As shown in fig. 10, it can be seen that portions of the inner wall of the through-hole extend inwardly and may form a discontinuous annular configuration. According to different requirements, the structure shown in fig. 9 can ensure good supporting effect. And other extension structures like fig. 10 or fig. 11 can reduce the consumption of the consumable on the basis of ensuring the supporting effect.
Further, the fixing assembly 1 comprises a fixing piece 12 and a connecting piece 13 which are connected with each other, wherein the fixing piece 12 is used for being movably connected with the supporting piece 2, and the connecting piece 13 is used for being movably connected with the lower beam 6; the connecting piece 13 is made of metal, and the fixing piece 12 is made of plastic.
As shown in fig. 6 and 7, the fixing assembly 1 may be constructed of two-part members of a fixing member 12 and a connecting member 13 connected to each other. When the fixing member 12 and the connecting member 13 are connected to each other to form the fixing assembly 1, the fixing member 12 may be used to be movably connected to the lower beam 6, and the connecting member 13 may be used to be movably connected to the supporting member 2 to switch the sliding function and the supporting function of the frame structure.
Therefore, different materials can be used for the fixing member 12 and the connecting member 13 based on the difference in the functions of the fixing member 12 and the connecting member 13. For example, the fixing member 12 may be made of metal, and is connected to the lower beam 6 more firmly; the connecting piece 13 can be made of plastic and other materials, so that the hardness is lower, the damage to the ground 9 can be avoided, and the cost is lower. The metal material of the fixing member 12 may be optional according to the requirement, and the plastic type of the connecting member 13 may also be optional according to the requirement, which is not limited herein.
Since the connecting member 13 is used for movably connecting with the lower beam 6, various first height-adjusting structures are arranged on at least one of the connecting member 13 and the lower beam 6. For example, when the first thread height-adjusting structure 3 is used between the fixing assembly 1 and the lower beam 6, a first external thread may be disposed on the outer surface of the connecting member 13, so as to be movably sleeved with a threaded hole preset on the lower beam 6, and so on for other types of first height-adjusting structures.
Since the fixing member 12 is used for being movably connected with the supporting member 2, each type of second height-adjusting structure is disposed on at least one of the supporting member 2 and the fixing member 12. For example, when the second thread height-adjusting structure 4 is used between the fixing member 1 and the supporting member 2, a second external thread may be provided on the outer surface of the fixing member 12 so as to be movably sleeved with the supporting member 2, and so on. Meanwhile, the stopper portion 11 may be provided on the fixing member 12.
The invention also provides refrigeration equipment comprising the frame structure. Since the specific structure, functional principle and technical effect of the frame structure are described in detail in the foregoing, and the refrigeration device includes a refrigerator 7, an ice chest, a freezer, etc., the foregoing is also described by taking the refrigerator 7 as an example, and thus, no further description is given here.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
