DETAILED DESCRIPTION

[0027] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the various embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments described in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] As Figure 1 and Figure 2 shown, this embodiment discloses a simple anti-theft door, which is used in cooperation with a door frame and has a good anti-theft function. The structure is arranged as a bottom frame 1, a top frame 2 and a middle frame 3 installed in sequence from bottom to top. Four vertical side frames 4 are arranged therebetween, thus forming an overall "day"-shaped frame. Then, two door panels 5 are fastened by bolts in the upper and lower spaces of the frame, and a heat-insulating foam 53 is clamped between the two door panels 5. Among them, the mechanisms of the bottom frame 1 and the top frame 2 are basically the same and are mirror images. Therefore, the main materials required are 2 bottom frames (or top frames), 1 middle frame, 4 side frames, four door panels 5 and two heat-insulating foams 53. The overall outer shapes of these several parts are regular rectangles, which are very convenient for stacking, storing and transporting. Moreover, during installation, the only tools required are a screwdriver or common power tools. These two are very commonly used at construction sites or when building temporary shelters. Compared with the doors used in existing temporary buildings, it is very convenient. And it has a relatively high safety factor and strong anti-theft ability.

[0029] In addition, two necessary ropes mentioned below are also required to be matched. The lock core mechanism 6 on the middle frame 3 can be transported separately or installed on the middle frame 3 for transportation together. When installing on the middle frame 3, the inner and outer handles can be removed first. In addition, in order to obtain a good user experience, the heat-insulating foam 53 used for heat insulation can be used in combination.

[0030] In addition, screw holes can be reserved on the side frame 4 for installing hinges so as to be installed on the door frame.

[0031] The structure of this device will be described in detail below.

[0032] As shown in the attached Figure 3 to the attached Figure 4 figures, a spring chamber with a downward opening is provided in the bottom frame 1. A lock rod mechanism 7 and a spring are movably arranged in the spring chamber. A baffle 71 is provided at the opening of the spring chamber. The spring pushes the lock rod of the lock rod mechanism 7 out of the baffle 71 and inserts it into the locking hole at the lower part of the door frame to lock the door.

[0033] A rope hole 11 is provided on the top surface of the bottom frame 1, which communicates with the spring chamber below. Another rope is matched and passes through this rope hole 11 and is connected to the internal lock rod mechanism 7. By pulling the rope, the lock rod of the lock rod mechanism 7 is pulled back into the spring chamber to achieve the unlocking function.

[0034] The outer edge of the baffle 71 is provided with threads and is installed at the opening of the spring chamber by a threaded connection method. Two pinholes 72 are provided on the baffle 71. The provided pinholes 72 can be used for inserting tweezers or other thin rod-shaped tools, so as to rotate the baffle 71 to remove it.

[0035] The end of the lock rod is rounded to form a smooth arc surface. The door frame is provided with matching inclined surfaces at the top and bottom. Guided by the inclined surfaces, the lock rod can smoothly retract when the door is closed, and then pop out and snap into the lock hole of the door frame after the door is closed. In order to better prevent theft, the door is generally set to open inwards, so that the inclined surface is located indoors.

[0036] As attached Figure 5 As shown, the function of the top frame 2 is exactly the same as that of the bottom frame 1, so the structure is also basically the same, the only difference is that the locking rod mechanism 7 in the spring compartment pops out the locking rod upward. Therefore, the structure of the top frame 2 is designed to be symmetrical with the bottom frame 1, and the spring compartment is located on the same vertical line, and its spring compartment opening is arranged upward.

[0037] As attached Figure 6 and attached Figure 7 As shown, the middle frame 3 is provided with a lock core bin located on the same vertical line as the spring bin, a lock core mechanism 6 is installed in the lock core bin, the lock core bin is provided with an opening toward the back of the door, and a cover plate 31 is bolted to the opening; rope holes 11 are provided above and below the lock core bin; the lock core mechanism 6 is rotatably connected to a winding wheel, and two groups of coils are wound on the winding wheel, and the two groups of coils are respectively connected to the pull ropes from the spring bins of the bottom frame 1 and the top frame, and the winding directions of the two pull ropes are opposite. The opposite winding directions enable the pull ropes in two different directions to be recovered or released at the same time when the winding wheel rotates.

[0038] After the lock core mechanism 6 is unlocked, it drives the winding wheel to rotate, thereby pulling and recovering the two pull ropes, so that the locking rod is retracted into the spring compartment to achieve unlocking; the lock core mechanism 6 is provided with an outer handle 62 on the front and an inner handle 61 on the back; the outer handle 62 is provided with a keyhole for inserting a key to unlock the lock core mechanism.

[0039] As attached Figure 3 To Attachment Figure 7 As shown, two symmetrically distributed inverted isosceles trapezoidal grooves 9 are provided on the facing surfaces of the bottom frame 1 and the middle frame 3, as well as on the facing surfaces of the top frame 2 and the middle frame 3; threaded holes 8 are provided on the back of the bottom frame 1, the middle frame 3 and the middle frame 3, and the threaded holes 8 pass through the first groove until they are connected to the second groove.

[0040] As attached Figure 8 As shown, the side frame 4 is provided with two symmetrical square grooves 41 opening inwardly; a threaded hole 8 is provided on the back of the side frame 4, and the threaded hole 8 passes through the first groove until it is connected to the second groove.

[0041] When assembling this device, first place the bottom frame 1 on a plane, then insert two door panels 5 into the trapezoidal grooves 9, and then install the side frames 4 on both sides, ensuring that the two sides of the door panel 5 are snapped into the two square grooves 41 of the side frame 4. Finally, install the middle frame 3 on top of the door panel 5. At this time, the lower half of the "day"-shaped door is built. By screwing bolts into each threaded hole 8, the assembly can be completed.

[0042] In this process, it is necessary to connect the pull rope and the lock core mechanism. Therefore, when installing the side frame 4, first pass the pull rope through the rope hole 11 of the side frame 4, connect the lower end to the lock rod mechanism 7, and when installing the middle frame 3 at the upper end, pass it into the lock core chamber and connect it to the coil on the winding wheel.

[0043] Next is to build the upper half: Insert two door panels 5 into the trapezoidal grooves 9 in the upper part of the middle frame 3, and then install the side frames 4 on both sides, ensuring that the two sides of the door panel 5 are snapped into the two square grooves 41 of the side frame 4. Finally, install the top frame 2 on top of the door panel 5. At this time, the upper half is built. By screwing bolts into each threaded hole 8, the assembly of the entire door can be completed.

[0044] The installation of the pull rope in the upper half is the same as that in the lower half.

[0045] The installation of the door panel 5 mainly relies on the connection and fixation of bolts. To ensure safety, the direction of the screw holes should be set to open holes on the back. In this way, there is no opening on the front of the door, and it is impossible to拆除进入 (the original text seems to be incomplete here, perhaps "拆除进入" should be "拆除并进入", but translated as is for now) from the front.

[0046] As shown in the attachment Fig. 9 The door panel 5 is arranged in the space surrounded by the isosceles trapezoidal groove 9 and the square groove 41, and through holes 52 are provided corresponding to the threaded holes 8 for bolts to pass through, so as to be firmly connected to the frame. Chamfers 51 are provided at the four corners of the door panel 5 to fit the waist edges of the trapezoidal groove 9.

[0047] Again as shown in the attachment Figure 3 To the attachment Figure 8 As shown, pin holes 10 are provided on the top surface of the bottom frame 1, the bottom surface of the top frame 2, and the upper and lower surfaces of the middle frame 3, and positioning pins are placed in the pin holes 10; the top surface of the side frame 4 is also provided with pin holes 10 corresponding to the above components for positioning during installation.

[0048] The heat-insulating foam 53 of this device is not a necessary item. Therefore, in an environment with not-so-severe climate, this component can be saved, further reducing costs. And the structural design of the double-layer door panel 5 already has good heat-insulating and sound-insulating functions.

[0049] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view. The scope of the present invention is defined by the appended claims, rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0050] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
