Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated cabins, and more specifically, to a door lock structure and a prefabricated cabin structure comprising the same. Background Art

[0002] In the current energy storage field, as an efficient and flexible energy storage solution, the internal layout and configuration of prefabricated cabins are particularly critical. In order to meet the growing demand for power storage, a large number of battery packs are arranged in the prefabricated cabins, which are closely arranged to form a huge energy storage system. However, this configuration also brings a problem that cannot be ignored - the weight of the prefabricated cabin increases sharply.

[0003] Taking a 20-foot prefabricated cabin as an example, after loading liquid cooling equipment and its complex piping system, electrical control cabinets, fire safety equipment and a large number of battery packs, its weight can easily reach 45 tons or even higher. Such weight not only increases the difficulty of transportation and installation, but also puts higher requirements on the structural strength of the prefabricated cabin.

[0004] However, the problem does not stop there. Due to the different distribution of gravity on the prefabricated cabin when it is empty and fully loaded, as well as the possible flatness of the ground at the installation site, these may cause slight deformation of the door frame of the prefabricated cabin. Although this deformation seems insignificant, it is enough to cause misalignment between the locking pin of the prefabricated cabin door and the support on the frame.

[0005] In the design of the prefabricated cabin door lock, the matching accuracy between the lock pin and the support is extremely high. The tolerance distance between them is very small. Once the door frame or door is slightly deformed, the two will not be able to fully match. In this case, even if the operator pushes hard, the door lock of the prefabricated cabin cannot be completely closed and locked.

[0006] This problem of door lock failure is very serious for prefabricated cabins. Once the door lock cannot be completely closed, the IP protection level of the prefabricated cabin will be invalidated, and external rain, dust and other harmful substances may invade the cabin. This will not only damage the equipment in the cabin, but also cause safety accidents and cause the energy storage system to fail to operate normally.

[0007] Therefore, how to effectively solve the problem of failure of prefabricated hatch door locks has become a technical problem that needs to be solved urgently. Utility Model Content

[0008] The main purpose of the utility model is to provide a door lock structure and a prefabricated cabin structure comprising the same, aiming to solve the problem that the door lock cannot be used normally due to misalignment between the door frame and the door.

[0009] In order to solve the above technical problems, on the one hand, a door lock structure is proposed, comprising: a lock pin assembly and a lock seat assembly, wherein:

[0010] The locking pin assembly comprises: a pin shaft, and a male end portion is disposed on the side of one end portion of the pin shaft;

[0011] The lock seat assembly comprises: a female end portion, on which is formed an escape groove for the male end portion on the pin shaft to be embedded after the pin shaft rotates in the closing direction, and the groove width of the escape groove in the axial direction of the pin shaft is greater than the width of the male end portion in the axial direction of the pin shaft;

[0012] When the pin shaft rotates to a maximum angle along the opening direction, the male end portion on the pin shaft slides in the avoidance groove and gradually escapes from the avoidance groove.

[0013] In the above technical solution, further, the female end portion includes: a female end plate and two connecting plates arranged on the female end plate, and the cavity enclosed by the female end plate and the two connecting plates forms the avoidance groove.

[0014] In any of the above technical solutions, further, the lock seat assembly also includes: a side plate;

[0015] Wherein, the female end portion is arranged on the side plate.

[0016] In any of the above technical solutions, further, the connecting plate is a triangular plate structure, and the hypotenuse end face of the connecting plate forms the port end face of the avoidance groove.

[0017] In any of the above technical solutions, further, the male end portion is a plate-like structure, and its end portion is an arc surface; the inner wall of the avoidance groove is an arc surface that matches the arc surface on the end portion of the male end portion.

[0018] In any of the above technical solutions, further, the locking pin assembly also includes:

[0019] Locking rod;

[0020] Wherein, the pin shaft is arranged on the locking rod, and the pin shaft and the locking rod are connected as a whole.

[0021] In any of the above technical solutions, further, a handle is provided on the locking rod.

[0022] In any of the above technical solutions, further, the end of the pin shaft has an auxiliary limiting portion arranged opposite to the male end; the lock seat assembly also includes: an auxiliary supporting portion;

[0023] Wherein, during the rotation of the pin shaft along the closing direction, the male end portion is gradually embedded in the avoidance groove, and the auxiliary limiting portion gradually approaches the auxiliary supporting portion until it abuts against the auxiliary supporting portion.

[0024] On the other hand, a prefabricated cabin structure is also provided, comprising: a box body, a door frame arranged on the box body, and at least one box door arranged on the door frame, wherein at least one of the above-mentioned door lock structures is also included;

[0025] Wherein, the female end portion is arranged on the door frame, and the locking rod is arranged on the box door.

[0026] In any of the above technical solutions, further, a sealing gap is provided between the box door and the door frame, and a sealing member is provided in the sealing gap;

[0027] The size of the sealing gap is A. When the male end portion is located in the avoidance groove, the sizes of the gaps between the male end portion and the avoidance groove in the axial direction of the pin shaft are B1 and B2 respectively, which are used to accommodate the offset distance when the door frame and the door are deformed, so as to prevent the lock pin assembly from being stuck by the lock seat assembly.

[0028] Among them, B1≤20A, B2≤20A.

[0029] Beneficial effect: Compared with the prior art, by setting the width of the avoidance groove larger than the width of the male end, it can be ensured that when the door frame and the box door are slightly deformed, the door lock structure can continue to be used to open or close the box door on the door frame.

[0030] An auxiliary limiting portion and an auxiliary supporting portion are provided. When the pin shaft rotates to make the male end portion gradually rotate into the avoidance groove, the auxiliary limiting portion on the pin shaft gradually approaches the auxiliary supporting portion and presses against the auxiliary supporting portion. The rotation of the pin shaft is limited by the auxiliary supporting portion, so that the pin shaft is firmly stuck in the female end portion and will not loosen. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The utility model provides a prefabricated cabin structure and a door lock structure used for the prefabricated cabin structure, so as to solve the problem that the existing door locks cannot be used.

[0049] The prefabricated cabin structure and door lock structure of the present application are described in detail through the following embodiments.

[0050] Embodiment 1:

[0051] like Figure 1 and Figure 2 As shown, in this embodiment, a prefabricated cabin structure is provided, including a box body 10, a door frame 20 arranged on the box body 10, and at least one box door 30 hinged on the door frame 20, wherein a door lock structure is also included, and the box door 30 is locked to the door frame 20 through the door lock structure.

[0052] A sealing gap is provided between the door frame 20 and the door 30, and then a sealing member is filled in the sealing gap, and the sealing member can be a rubber strip or other material. The design of the sealing gap allows the door frame 20 and the door 30 to fit tightly when closed, but will not cause difficulty in opening and closing or damage the sealing material due to over-tight fitting. The sealing member filled in the sealing gap, such as a rubber strip, can effectively fill the tiny gap between the door frame 20 and the door 30, thereby preventing the entry of external impurities such as rainwater and dust.

[0053] The width of the sealing gap is A, where the value range of A is 1.5-35 mm. A relatively reasonable sealing gap is set. After the seal is filled in the sealing gap, it can ensure both the convenience of installation and a good sealing effect.

[0054] Embodiment 2:

[0055] This embodiment is a further improvement made on the basis of the first embodiment.

[0056] like Figure 1-Figure 3 As shown, in this embodiment, a door lock structure for the above-mentioned prefabricated cabin structure is provided, through which not only the door 30 can be opened and closed conveniently, but also the door 30 and the door frame 20 can be ensured to continue to be used after relative misalignment occurs.

[0057] Specifically, the door lock structure includes: a lock pin assembly 100 and a lock base assembly 200. The lock pin assembly 100 and the lock base assembly 200 cooperate with each other to achieve the opening and closing of the box door 30.

[0058] The locking pin assembly 100 includes: a locking rod 110, which is arranged on the box door 30 in a vertical direction and can rotate in a directional manner; a pin shaft 120, which is arranged on the locking rod 110, and the pin shaft 120 is connected to the locking rod 110 as a whole, and a male end portion 130 is arranged on the side of one end of the pin shaft 120.

[0059] The lock seat assembly 200 includes: a female end portion 210, which is fixed on the door frame 20, and an avoidance groove 201 is formed on the female end portion 210 for the male end portion 130 on the pin shaft 120 to be embedded in after the pin shaft 120 rotates in the closing direction, and the groove width of the avoidance groove 201 in the axial direction of the pin shaft 120 is greater than the width of the male end portion 130 in the axial direction of the pin shaft 120.

[0060] When the pin shaft 120 rotates to a maximum angle along the opening direction, the male end portion 130 on the pin shaft 120 slides in the avoidance groove 201 and gradually escapes from the avoidance groove 201 .

[0061] By arranging the male end portion 130 on the pin shaft 120 and the avoidance groove 201 on the female end portion 210, the lock rod 110 is rotated, and the lock rod 110 drives the pin shaft 120 to rotate. When the male end portion 130 on the pin shaft 120 is embedded in the avoidance groove 201, the lock pin is locked on the female end portion 210, so that the box door 30, the lock rod 110, the pin shaft 120, the female end portion 210 and the door frame 20 are connected to each other to form an integrated structure, so that the box door 30 is closed on the door frame 20 and the box door 30 is locked;

[0062] When the lock rod 110 is rotated, the lock rod 110 drives the pin shaft 120 so that the male end portion 130 thereof is disengaged from the avoidance groove 201. At this time, the pin shaft 120 is disengaged from the female end portion 210, that is, the box door 30 and the door frame 20 are in an unlocked state, and the box body 10 can be opened by rotating the box door 30.

[0063] Furthermore, by setting the width of the avoidance groove 201 to be larger than the width of the male end 130 , it is ensured that when the door frame 20 and the door 30 are slightly deformed, the door lock structure can continue to be used to open or close the door 30 on the door frame 20 .

[0064] It should be noted that the lock rod 110 is also provided with a handle 111, through which an external force can be easily applied to the lock rod 110 to rotate it, thereby realizing unlocking and locking.

[0065] It should be noted that when the male end portion 130 is located in the avoidance groove 201, the dimensions of the gap between the male end portion 130 and the avoidance groove 201 in the axial direction of the pin shaft 120 are B1 and B2 respectively; B1 and B2 are used to accommodate the offset distance when the door frame 20 and the box door 30 are deformed, to prevent the lock pin assembly from being stuck by the lock seat assembly; wherein, B1≤20A, B2≤20A.

[0066] like Figure 3As shown, in the normal state, that is, the box door 30 and the door frame 20 are not deformed, and the locking rod 110 will not deflect upward or downward. Therefore, when the male end portion 130 enters the avoidance groove 201, the gaps between the male end portion 130 and the avoidance groove 201 in the axial direction of the pin shaft 120 are B1 and B2 respectively. Preferably, at this time, the male end portion 130 is located in the middle position of the avoidance groove 201, that is, B1 and B2 are the same. When the door 30 and the door frame 20 are deformed, the seal will be squeezed and the sealing gap 40 will become smaller. At this time, the locking rod 110 will move upward or downward. In any case, B1 and B2 will change. If B1 increases, B2 decreases, and if B1 decreases, B2 increases. In order to ensure that the amplitude of the up and down movement of the male end 130 in the avoidance groove 201 is greater than the amplitude of the up and down movement of the locking rod 110 after the door 30 and the door frame 20 are deformed, B1≤20A and B2≤20A are set. In practice, the maximum amplitude of the up and down movement of the locking rod 110 is about 0.66A. For this reason, B1 and B2 can be set to 0.66A.

[0067] Embodiment three:

[0068] This embodiment is a further improvement made on the basis of the second embodiment.

[0069] like Figure 4-Figure 6 As shown, in this embodiment, the lock base assembly 200 further includes: a side plate 220 for fixing on the door frame 20.

[0070] The female end portion 210 includes a female end plate 211 and two connecting plates 212 . The two connecting plates 212 are used to connect the female end plate 211 to the side plate 220 .

[0071] The cavity enclosed by the female end plate 211 , the two connecting plates 212 and the side plates 220 forms an avoidance groove 201 .

[0072] In order to facilitate the male end portion 130 to be embedded in the avoidance groove 201, the connecting plate 212 is set to a triangular plate structure, and the hypotenuse end surface of the connecting plate 212 forms the port end surface of the avoidance groove 201. The male end portion 130 is set to a plate-like structure, and the end is set to an arc surface, and the inner wall of the avoidance groove 201 is an arc surface that matches the arc surface on the end of the male end portion 130. After such a setting, when the locking rod 110 drives the pin shaft 120 to rotate, the surface where the end of the male end portion 130 contacts the inner wall of the avoidance groove 201 is smooth and will not be stuck, causing the pin shaft 120 to be unable to rotate.

[0073] Embodiment 4:

[0074] This embodiment is a further improvement made on the basis of the second and third embodiments.

[0075] like Figure 1 , Figure 2 , Figure 7-Figure 9 As shown, in this embodiment, the difference from the second and third embodiments is that an auxiliary limiting portion 140 is provided at the end of the pin shaft 120 and is disposed opposite to the male end portion 130; the lock seat assembly 200 further includes: an auxiliary supporting portion 230;

[0076] When the pin shaft 120 rotates in the closing direction, the male end portion 130 is gradually embedded in the avoidance groove 201 , and the auxiliary limiting portion 140 gradually approaches the auxiliary supporting portion 230 until it abuts against the auxiliary supporting portion 230 .

[0077] In order to further improve the limiting effect of the female end 210 on the pin shaft 120, an auxiliary limiting portion 140 and an auxiliary supporting portion 230 are provided. When the pin shaft 120 rotates to make the male end 130 gradually rotate into the avoidance groove 201, the auxiliary limiting portion 140 on the pin shaft 120 gradually approaches the auxiliary supporting portion 230 and presses against the auxiliary supporting portion 230. The rotation of the pin shaft 120 is limited by the auxiliary supporting portion 230, so that the pin shaft 120 is firmly stuck in the female end 210 and will not loosen.

[0078] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
