Description

Technical Field

[0001] The utility model belongs to the technical field of door lock structures, and particularly relates to a locking structure and a door body component. Background Art

[0002] In order to facilitate the transportation or maintenance of equipment inside the air-conditioning box, the air-conditioning box is usually provided with corresponding inspection doors or movable doors, and in order to ensure the airtightness and thermal insulation performance of the air-conditioning box, the door body is generally fixed to the frame or other structure by bolts directly passing through the insulation board.

[0003] However, in actual use, it was found that the locking structure of the door body still had the following problems:

[0004] 1) Since the fixing bolts completely penetrate the insulation inspection door, the insulation structure will be damaged, and there will be risks of air leakage and energy transfer, which will seriously affect the sealing and insulation of the air-conditioning box.

[0005] 2) For the bolt-fixed structure, there are problems such as difficulty in disassembly and assembly, and the large number of door lock structural parts affects the disassembly and assembly efficiency.

[0006] 3) The door locking structure fixed with bolts requires built-in threaded holes on the door body and door frame. In the actual processing process, the hole positions often deviate. Therefore, if the centers are inconsistent, the bolts cannot be installed smoothly. If forced installation is performed, the bolts are easily damaged, thus affecting the airtightness and thermal insulation of the door body. Utility Model Content

[0050] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0051] The most critical concept of the present invention is that when the door frame and the door body are closed, the locking member is moved toward the door frame to drive the lock tongue assembly and the door body to move toward the door frame at the same time, so that the door body can further fit with the door frame, thereby ensuring the airtightness of the door frame and the door body, avoiding heat exchange between internal and external gases and affecting the overall thermal insulation; and eliminating multiple bolt locking actions, thereby effectively improving the overall locking efficiency.

[0052] Please refer to Figure 1 to Figure 2 The locking structure provided by the utility model comprises a locking assembly 1 and a locking tongue assembly 2;

[0053] The locking assembly 1 includes a locking member 11 whose movable end can be close to or away from the locking tongue assembly 2;

[0054] The locking tongue assembly 2 includes a locking tongue body slidably connected thereto;

[0055] When the locking assembly 1 and the locking tongue assembly 2 are closed, the locking member 11 presses the locking tongue body toward the locking tongue assembly 2 .

[0056] From the above description, it can be seen that the beneficial effects of the utility model are: providing a locking structure, when the locking assembly 1 and the lock tongue assembly 2 are closed, the locking piece 11 is moved toward the lock tongue assembly 2 to drive the lock tongue assembly 2 to further fit the locking assembly 1; compared with the existing locking structure, different locking forms are achieved by changing the structure, that is, the existing door body can either only completely penetrate the door frame and the door body through bolts to achieve the fixing effect of the two, or directly use ordinary door locks to fix the door frame and the door body, but these two existing locking forms will bring corresponding poor thermal insulation performance and unsatisfactory airtightness problems, and the locking structure of the present scheme, after any door frame and door body are initially locked, can further make the door body fit the door frame through the locking assembly 1, thereby ensuring the airtightness of the door frame and the door body, avoiding heat exchange between internal and external gases and affecting the overall thermal insulation, and eliminating multiple bolt locking actions, thereby effectively improving the overall locking efficiency.

[0057] The utility model also provides a door body assembly, comprising a door frame, a door body and the above-mentioned locking structure;

[0058] The locking assembly 1 is arranged on the door frame;

[0059] The lock tongue assembly 2 is arranged on the door body;

[0060] When the door frame and the door body are closed, the locking member 11 presses the lock tongue body toward the door frame.

[0061] The door body assembly of this solution is preferably a swing door.

[0062] It can be seen from the above description that the locking structure of the present solution can be combined with any swing door, thereby effectively improving the overall airtightness and heat preservation performance of the swing door.

[0063] Furthermore, the locking structure also includes a threaded member 3;

[0064] The door frame is provided with at least two first blind holes;

[0065] The door body is provided with at least two second blind holes;

[0066] The locking assembly 1 is threadedly connected to the first blind hole via a threaded member 3;

[0067] The locking tongue assembly 2 is threadedly connected to the second blind hole via a screw member 3 .

[0068] From the above description, it can be seen that the design has made specific modifications to the connection method between the locking assembly 1 and the door frame, and the connection method between the lock tongue assembly 2 and the door body. Since the locking structure does not need to completely penetrate the door frame and the door body to ensure the airtightness after locking, the basic fixing requirements of the locking assembly 1 and the door frame, and the lock tongue assembly 2 and the door body can be achieved only through the first blind hole and the second blind hole; at the same time, the blind holes can also greatly ensure the completion of the door frame and the door body, avoiding damage to the door frame and the door body, thereby affecting the overall airtightness and thermal insulation.

[0069] Furthermore, the locking assembly 1 further includes a first fixing member 12;

[0070] The locking member 11 is connected to the door frame through the first fixing member 12;

[0071] In the thickness direction of the first fixing member 12, a groove-shaped structure 121 with one end open and the other end closed is provided;

[0072] One end of the groove structure 121 close to the door frame is an open end;

[0073] One end of the groove structure 121 away from the door frame is a closed end;

[0074] The locking member 11 can reciprocate along its own axis in the groove structure 121 , and the movable end of the locking member 11 is disposed toward the door frame.

[0075] Furthermore, the locking tongue assembly 2 further includes a second fixing member 21;

[0076] The bolt body is connected to the door body through a second fixing member 21;

[0077] The second fixing member 21 is provided with an oblong hole 211;

[0078] The bolt body is slidably connected to the second fixing member 21 through the oblong hole 211;

[0079] When the door frame and the door body are closed, the lock tongue body is disposed toward the bottom of the groove structure 121 , and the moving path of the lock tongue body and the moving path of the locking member 11 intersect in the groove structure 121 .

[0080] From the above description, it can be seen that the design further optimizes the structure of the locking assembly 1 and the lock tongue assembly 2. The oblong hole 211 enables the lock tongue body to be slidably connected to the second fixing member 21; and a groove structure 121 with one end open and the other end closed is provided on the first fixing member 12. After the lock tongue body moves to the specified position and is pressed against the lock tongue body by the locking member 11, the lock tongue body can be further driven by the locking member 11 to move toward the door frame along the length direction of the groove structure 121, thereby indirectly driving the door body to be further close to the door frame, thereby ensuring the overall air tightness and thermal insulation.

[0081] Furthermore, the bolt body includes a movable handle 22 and a lock head 23;

[0082] The lock head 23 is slidably connected to the oblong hole 211 through the movable handle 22;

[0083] When the door frame and the door body are closed, the lock head 23 is disposed toward the bottom of the groove structure 121 , and the moving path of the lock head 23 intersects with the moving path of the locking member 11 in the groove structure 121 .

[0084] Furthermore, the second fixing member 21 further includes a guide limiting groove 212;

[0085] The extending direction of the guide limiting groove 212 is parallel to the extending direction of the oblong hole 211;

[0086] Part of the structure of the lock head 23 is located in the guide limiting groove 212 , and the lock head 23 can reciprocate in the guide limiting groove 212 along the extension direction of the guide limiting groove 212 .

[0087] From the above description, it can be seen that the design has further optimized the composition structure of the lock tongue body and the second fixing member 21. By moving the handle 22 and the oblong hole 211, and the lock head 23 and the guide limit groove 212, the stability of the lock head 23 during the movement can be ensured, and the lock head 23 can be prevented from shaking or deviating, which may cause the subsequent locking member 11 to be unable to be smoothly pressed against the lock head 23.

[0088] Furthermore, sealing members are provided at the joints between the door frame and the door body;

[0089] When the door frame and the door body are closed, the door body is pressed against the door frame, and the sealing member on the door frame contacts the sealing member on the door body.

[0090] From the above description, it can be seen that even if the processing accuracy of the door frame and the door body is high, there will inevitably be a gap between the two. Therefore, a seal is set at the joint between the two, and in the subsequent process of the door body squeezing the door frame, elastic deformation can be generated between the seals, thereby filling the gap between the door frame and the door body, thereby ensuring the overall airtightness and avoiding heat exchange between the inside and the outside, which affects the thermal insulation.

[0091] Furthermore, the above-mentioned door assembly also includes a pressure detection member;

[0092] When the door frame and the door body are closed, the door body contacts the door frame through the pressure detection member.

[0093] From the above description, it can be seen that in the process of the locking assembly 1 gradually driving the door body to move toward the door frame, the pressure detection component will detect the pressure exerted on the door control in real time to avoid damage to the lock tongue assembly 2 or the door frame due to excessive pressure applied by the locking assembly 1.

[0094] Furthermore, the locking assembly 1 also includes a driving member;

[0095] The movable end of the driving member is connected to the locking member 11, and the driving member can drive the locking member 11 to move closer to or away from the door frame.

[0096] Furthermore, the locking structure also includes a switch member and a controller;

[0097] The switch member is arranged at the bottom of the groove of the groove structure 121, and the switch member is located on the moving path of the lock head 23;

[0098] The switch element, the driving element and the pressure detection element are all electrically connected to the controller.

[0099] From the above description, it can be seen that the design further optimizes the locking structure from the perspective of automation. When the lock head 23 hits the switch part on the bottom of the groove of the groove structure 121, the corresponding locking signal can be sent from the controller to the driving part; then the driving part drives the locking part 11 to move toward the lock head 23. When the locking part 11 hits the lock head 23, the door body can be driven to further fit the door frame; finally, after the pressure value of the door body squeezing the door frame reaches the set value, the stop signal is sent from the controller to the driving part through the pressure detection part, so as to realize the fully automatic locking of the door body, thereby effectively improving the overall locking efficiency.

[0100] The locking structure of the utility model can be used for the sealing and locking work of the inspection door or movable door of the heat preservation air conditioner box body, and can also be used for the sealing and locking work of the general swing door.
