Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 One embodiment provided by this utility model:

[0026] A door frame type sealing strip clamping mechanism includes a door frame body 100, a closed door body 110, and a connecting rotating arm 120 fixed to the outer wall of the closed door body 110. The outer end of the connecting rotating arm 120 is hinged to a hinge seat 121 via a pivot pin 122, and the hinge seat 121 is fixed to the outer wall of the door frame body 100. A sealing strip 130 is filled between the side of the closed door body 110 and the inner wall of the door frame body 100, and the sealing strip 130 is fixed to the outer wall of the side of the closed door body 110. Limiting rods 140 are installed on the opposite outer walls of the two sets of closed door bodies 110. Furthermore, the outer wall of the limiting rod 140 is fitted with an assembly sleeve 142, which is fixed to the outer wall of the closed door 110. The upper and lower ends of the outer wall of the door frame 100 are fitted with end sleeves 141 corresponding to the ends of the limiting rod 140. An elliptical locking block 150 is abutted in the middle of the limiting rod 140. A rotating rod 160 is fixed inside the elliptical locking block 150. Both ends of the rotating rod 160 are fitted with installation kits 161, which are mounted on the outer wall of the closed door 110. A pressure strip 170 is integrally provided in the middle of the rotating rod 160.

[0027] Furthermore, the enclosed door 110 consists of a door frame 111 and a door panel 112. Four sets of door frames 111 are welded together to form a frame, and the door panel 112 is welded to the inside of the door frame 111. The outer wall of the door frame 111 is fixed to the connecting arm 120 by rivets, and the door panel 112 is fixedly equipped with a viewing plate 113 at both the top and bottom. This design facilitates the assembly of the enclosed door 110 and subsequent observation of the internal situation.

[0028] Furthermore, a support column 171 corresponding to the pressure strip 170 is fixed in the center of the outer wall of the door frame body 100, and an insert strip 172 is integrally provided at the outer end of the support column 171. A slot 173 corresponding to the insert strip 172 is opened in the middle of the pressure strip 170, and the slot 173 is wider in the inner and narrower in the outer shape. A pressure tongue 174 is installed at the outer end of the insert strip 172 by rivets, and the pressure tongue 174 can be twisted. A grip sleeve 175 is sleeved at the bottom end of the pressure strip 170. This design facilitates the limiting and support of the pressure strip 170, making subsequent use more convenient.

[0029] Furthermore, a bearing is fitted between the inner wall of the mounting kit 161 and the outer wall of the rotating rod 160. Limiting rings 162 are provided on both sides of the mounting kit 161, and the limiting rings 162 are fixed to the outer wall of the rotating rod 160. This design facilitates the auxiliary rotation and limiting of the rotating rod 160, making subsequent use more convenient.

[0030] Furthermore, a pressing plate 144 is fixed to one end of the limiting rod 140 near the elliptical locking block 150, and a supporting slide plate 143 is provided below the pressing plate 144. The supporting slide plate 143 is sleeved on the outer wall of the limiting rod 140 and fixed to the outer wall of the closed door 110. A spring 145 is provided between the pressing plate 144 and the supporting slide plate 143, and the spring 145 is sleeved on the outer wall of the limiting rod 140. This design facilitates the auxiliary abutment and extension of the limiting rod 140, and facilitates the retraction of the limiting rod 140, making the opening operation more convenient.

[0031] Furthermore, an auxiliary pressure plate 146 is sleeved on the side surface of the limiting rod 140 near the assembly slide sleeve 142, and a second spring 147 is provided between the auxiliary pressure plate 146 and the assembly slide sleeve 142. The second spring 147 is sleeved on the outer wall of the limiting rod 140. This design facilitates the auxiliary popping of the limiting rod 140, making it easier for the limiting rod 140 to be pulled out from the end sleeve 141, making subsequent operations more convenient.

[0032] Working principle: During assembly and use, the connecting arm 120 facilitates the closure of the door 110 by pressing the sealing strip 130 against the interior of the door frame 100. Then, pressing down on the pressure plate 170 rotates the rotating rod 160, causing the elliptical locking block 150 to rotate. The long side of the elliptical locking block 150 then presses against the pressure plate 144, causing the limiting rod 140 to insert into the end sleeve 141, thus locking the door 110 and the door frame 100. Subsequently, the pressure plate 170 is engaged with the slot 173, the pressure tongue 174, and the insert 172. Twisting the pressure tongue 174 limits the pressure plate 170, thus assisting the support column 171 in limiting and blocking the pressure plate 170, facilitating the movement of the elliptical locking block 150 and the rotating rod. The stable support of 160 allows the limiting rod 140 and the end sleeve 141 to easily limit and block the space between the closed door 110 and the door frame body 100, facilitating tight closure and making subsequent use more convenient. When opening is needed later, the pressure tongue 174 is turned so that it is parallel to the insert strip 172, allowing the pressure plate strip 170 to be pulled upwards, thereby rotating the elliptical locking block 150 so that its short side faces the pressure plate 144. Under the elastic force of springs 145 and 147, the pressure plate 144 and auxiliary pressure plate 146 are moved, causing the limiting rod 140 to slide, allowing it to be pulled out from inside the end sleeve 141. This releases the limitation on the closed door 110, facilitating the opening of the closed door 110 via the connecting rotating arm 120, and facilitating subsequent operations. The operation ends here.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
