Description

Technical Field

[0001] The present invention relates to the technical field of door fittings, and in particular to a high-strength plastic protective device based on additive manufacturing. Background Art

[0002] Additive manufacturing technology is a technology that uses a gradual accumulation of materials to manufacture solid parts. Compared with traditional material removal-cutting processing technology, additive manufacturing technology does not require traditional tools and fixtures and multiple processing steps. It can quickly and accurately manufacture parts of any complex shape on a single device, thereby realizing the "free manufacturing" of parts, solving the forming of many complex structural parts, and greatly reducing the processing steps and shortening the processing cycle. Moreover, the more complex the product structure, the more significant the effect of its manufacturing speed. The protective device of this application refers to a gate structure enclosed in a designated area. In order to enhance the integrity and strength of the gate structure, this protective device is processed using additive manufacturing technology.

[0003] In the prior art, in order to improve the production efficiency of protective gates, the gate sizes are all standardized and uniformly produced as standard parts. However, in actual applications, the width of the space used to install the gates is not exactly the same. In this case, the standard parts produced cannot be installed in the space and can only be designed separately, wasting a lot of time and energy.

[0004] Chinese patent CN202467612U, published on October 3, 2012, discloses a gate railing assembly and a fixing member for the gate railing assembly. The gate railing assembly includes a gate railing and four fixing members, which are respectively fixed to the four corners of the gate railing. Each fixing member includes a fixing seat, a pivot rod and a fixing shaft. The fixing seat is fixed to the wall with a fixing plate, and a fixing rod receiving seat and a fixing ring are formed on the fixing plate. The fixing rod receiving seat is formed with a fixing plate. The door rail is fixed to a wall with four fixings, each of which has a longitudinal through-hole and a fixing ring aligned with the longitudinal through-hole. A ring is provided at one end of the pivot rod, which is positioned between the fixing rod receptacle and the fixing ring. The fixing shaft is positioned within the longitudinal through-hole and is elastically biased downward through the ring of the pivot rod and the fixing ring. In this way, the door rail can be fixed by fixing the four fixings to the wall surface. Pulling up the fixing shafts of two fixings on one side of the door rail allows the door rail to pivot, achieving both fixed and pivoting effects without the need for a telescopic lock on the door rail. However, this door rail assembly cannot be adjusted for installation width, making it unsuitable for installation in different spaces. Summary of the Invention

[0009] Furthermore, the connecting member includes a connecting cover for fixing one end of the horizontal bar and the horizontal column on the outside of the horizontal bar and the horizontal column, a connecting bottom shell for fixing one end of the horizontal bar and the horizontal column on the inside of the horizontal bar and the horizontal column, and a fixing member for fixing the connecting cover and the connecting bottom shell.

[0010] Furthermore, both ends of the connecting bottom shell are respectively provided with limiting grooves for limiting the two adjacent vertical bars and vertical columns, and the connecting cover is provided with accommodating grooves for accommodating the horizontal bars and horizontal columns.

[0011] Furthermore, the connection bottom shell is provided with a through hole, the connection cover is provided with a first threaded hole, and the fixing member is a screw with one end passing through the through hole and then being threadedly connected to the first threaded hole.

[0012] Furthermore, the other ends of the two horizontal columns are each connected to a fixing rod, and the fixing rod is provided with a protrusion at one end away from the end connected to the horizontal column. The second additive door frame is provided with a lock for fixing or loosening the two protrusions.

[0013] Furthermore, the fixing rod is provided with an external thread, the other end of the cross column is provided with a second threaded hole that matches the external thread, an adjusting nut is also provided in the middle of the fixing rod, and the protrusion is a circular protrusion.

[0014] Furthermore, the locking element includes a first locking buckle for fixing or releasing one of the protruding portions, and a second locking buckle for fixing or releasing the other of the protruding portions.

[0015] Furthermore, the first lock buckle is provided with a first slot with an open end for inserting one of the protrusions, and a button at the open end of the first slot for blocking or making way for the protrusion inserted in the first slot. The second lock buckle is provided with a second slot with an open end for inserting the other protrusion, and a knob at the open end of the second slot for blocking or making way for the protrusion inserted in the second slot. The first lock buckle is also provided with a reset spring with one end connected to the inner wall of the first lock buckle and the other end connected to the button.

[0016] The high-strength plastic protective device based on additive manufacturing of the present invention has the following advantages:

[0017] (1) When the protective device fixes one end of the first additive door fence and the second additive door fence together through a connecting piece, the connection length of the first additive door fence and the second additive door fence can be adjusted, so that the overall width of the first additive door frame, the first additive door fence, the second additive door fence and the second additive door frame is in an adjustable state, thereby allowing the first additive door frame and the second additive door frame to be installed in spaces of different widths, greatly enhancing the scope of application of the protective device;

[0018] (2) This protective device is achieved by sleeve-mounting the rotating rod at one end away from the end connected to the horizontal bar on the rotating shaft, so that the rotating rods at the other ends of the two horizontal bars are respectively rotatably connected to the rotating shafts in the two grooves, so that the ends of the two horizontal bars can rotate in the two grooves, thereby realizing the rotational connection between the first additive door fence and the first additive door frame;

[0019] (3) The connecting cover of the protective device is fixedly connected to one end of the horizontal bar and the horizontal column on the outside of the horizontal bar and the horizontal column, and the connecting bottom shell is fixedly connected to one end of the horizontal bar and the horizontal column on the inside of the horizontal bar and the horizontal column. The connecting cover and the connecting bottom shell are then fixedly connected together by the fixing piece, thereby realizing the fixed connection of the connecting piece to one end of the horizontal bar and the horizontal column;

[0020] (4) The two ends of the connecting bottom shell of the protective device are respectively provided with limiting grooves for limiting the two adjacent vertical bars and vertical columns, and the connecting cover is provided with a receiving groove for accommodating the horizontal bars and horizontal columns, so that when the connecting bottom shell and the connecting cover are connected to fix the horizontal bars and horizontal columns, the first and second augmented door bars are better limited, thereby enhancing the stability of the structure of the protective device;

[0021] (5) The protective device is provided with an external thread on the fixing rod, and a second threaded hole is provided at one end of the cross column where the fixing rod is connected. The fixing rod is screwed onto the cross column through the cooperation of the external thread and the second threaded hole, thereby achieving the connection between the cross column and the fixing rod. At the same time, by adjusting the screwing depth of the fixing rod in the second threaded hole, the overall width of the protective device can be further adjusted.

[0022] (6) The lock of the protective device includes a first lock buckle for fixing or releasing one protrusion, and a second lock buckle for fixing or releasing another protrusion. The two lock buckles are used to fix or release the second additive door fence at the same time. This can not only make the lock better in fixing the second additive door fence to the second additive door frame, but also prevent the second additive door fence from opening in the event of accidental contact, thereby increasing the safety of the protective device.

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] The embodiment of the present invention is a high-strength plastic protective device based on additive manufacturing, comprising a first additive door fence 1, a second additive door fence 2, a connector 3 for connecting one end of the first additive door fence 1 and one end of the second additive door fence 2, a first additive door frame 4 for rotatably connecting to the other end of the first additive door fence 1, and a second additive door frame 5 for fixing or loosening the other end of the second additive door fence 2; when the connector 3 connects the first additive door fence 1 and one end of the second additive door fence 2, the connection length of the first additive door fence 1 and the second additive door fence 2 can be adjusted. The specific effect is shown in FIG. Figure 1 .

[0038] In this application, the protective device is a two-piece gate, comprising a first additive gate 1 and a second additive gate 2. One end of the first additive gate 1 and the second additive gate 2 are fixedly connected by a connector 3, and the other end of the first additive gate 1 is rotatably connected to the first additive door frame 4. The second additive door frame 5 secures or releases the other end of the second additive gate 2. When the protective device is needed to partition a space, the second additive door frame 5 secures the other end of the second additive gate 2, thereby forming the first additive door frame 4, the first additive gate 1, the second additive gate 2, and the second additive door frame 5 into a single unit, which prevents people or pets outside the protective device from entering the area within the protective device, thereby providing protection. When the protective device needs to be opened to allow people or pets to pass through, the second additive door frame 5 releases the other end of the second additive door fence 2. Since the other end of the first additive door fence 1 is rotatably connected to the first additive door frame 4, the first additive door fence 1 and the second additive door fence 2 can be rotated inward or outward on the first additive door frame 4 to open. The inward and outward sides refer to the front and back in space. Rotating inward means rotating backward, and rotating outward means rotating forward.

[0039] In the present application, the first additive door fence 1, the second additive door fence 2, the first additive door frame 4 and the second additive door frame 5 are all made of plastic and are produced by additive manufacturing technology, so that the first additive door frame 4, the first additive door fence 1, the second additive door fence 2 and the second additive door frame 5 formed as a whole are stronger, thereby making the protective effect of the present protective device better.

[0040] In the prior art, in order to improve the efficiency of door rail production, door rails are all produced as standard parts with standardized uniform sizes. However, in actual application, the width of the space used to install the protective device is not exactly the same. At this time, the standard parts produced cannot be applied to the installation of spaces of different widths and can only be designed separately, wasting a lot of time and energy. In the present application, the first additive door fence 1 and the second additive door fence 2 are arranged alternately, and the connection length of the first additive door fence 1 and the second additive door fence 2 is the overlapping length of one end of the first additive door fence 1 and the second additive door fence 2. When the first additive door fence 1 and the second additive door fence 2 are fixedly connected at one end by the connecting member 3, the first additive door fence 1 and the second additive door fence 2 can be fixed at different lateral positions of the first additive door fence 1 and the second additive door fence 2, so that the overlapping length of one end of the first additive door fence 1 and the second additive door fence 2 is changed, that is, the total width of the first additive door fence 1 and the second additive door fence 2 after the fixed connection can be changed, so that the overall width of the first additive door frame 4, the first additive door fence 1, the second additive door fence 2 and the second additive door frame 5 is in an adjustable state, so that the first additive door frame 4 and the second additive door frame 5 can be installed in spaces of different widths, greatly enhancing the scope of application of this protective device.

[0041] In this embodiment, the first additive door fence 1 includes two horizontal bars 11 and a plurality of vertical bars 12 arranged vertically, and the ends of the plurality of vertical bars 12 are respectively connected to the two horizontal bars 11. The second additive door fence 2 includes two horizontal columns 21 arranged horizontally and a plurality of vertical columns 22 arranged vertically, and the ends of the plurality of vertical columns 22 are respectively connected to the two horizontal columns 21. The connecting members 3 are two connecting the two horizontal bars 11 and one end of the two horizontal columns 21. The specific effect is shown in FIG. Figure 1 、 Figure 3 and Figure 4 The first additive gate fence 1 includes two horizontal bars 11 and multiple vertical bars 12. The two horizontal bars 11 are arranged horizontally, and the multiple vertical bars 12 are arranged vertically. The two ends of the multiple vertical bars 12 are respectively connected to the two horizontal bars 11, thereby forming the first additive gate fence 1 into a network structure; the second additive gate fence 2 includes two horizontal columns 21 and multiple vertical columns 22. The two horizontal columns 21 are arranged horizontally, and the multiple vertical columns 22 are arranged vertically. The two ends of the multiple vertical columns 22 are respectively connected to the two horizontal columns 21, thereby forming the second additive gate fence 2 into a network structure.

[0042] In the present application, two connecting members 3 are provided, each used to connect one end of the two horizontal bars 11 and one end of the two horizontal posts 21, thereby fixing the first additive gate 1 and the second additive gate 2 together. Because the connecting members 3 can be connected at different axial positions of the horizontal bars 11 and the horizontal posts 21 when connecting the horizontal bars 11 and the horizontal posts 21, the connection length between the first additive gate 1 and the second additive gate 2 can be adjusted.

[0043] In this embodiment, two fixing blocks 41 are provided on the first additive door frame 4, and grooves 411 are provided on both fixing blocks 41. A rotating shaft 42 is provided on the two opposite inner walls of the groove 411. A rotating rod 13 is provided at the other end of each of the two horizontal bars 11. The end of the rotating rod 13 away from the connection with the horizontal bar 11 is provided with a sleeve 131 which is sleeved on the rotating shaft 42. The specific effect is shown in FIG. Figure 4 and Figure 5 By sleeve-mounting the sleeve 131 on the rotating rod 13 on the rotating shaft 42 , the rotating rod 13 is rotatably connected to the rotating shaft 42 in the two grooves 411 , so that the ends of the two horizontal bars 11 can rotate in the two grooves 411 , thereby realizing the rotatable connection between the first additive door fence 1 and the first additive door frame 4 .

[0044] After the first additive door fence 1 and the second additive door fence 2 are fixedly connected together by the connecting member 3, when the second additive door frame 5 fixes the other end of the second additive door fence 2, the first additive door fence 1 and the second additive door fence 2 are fixed together on the second additive door frame 5, so that the first additive door fence 1 and the second additive door fence 2 play a blocking role; when the second additive door frame 5 loosens the other end of the second additive door fence 2, the first additive door fence 1 and the second additive door fence 2 can be rotated inward or outward on the first additive door frame 4, so that the first additive door fence 1 and the second additive door fence 2 are opened.

[0045] In this embodiment, the connecting member 3 includes a connecting cover 31 for fixing one end of the horizontal bar 11 and the horizontal column 21 on the outside of the horizontal bar 11 and the horizontal column 21, a connecting bottom shell 32 for fixing one end of the horizontal bar 11 and the horizontal column 21 on the inside of the horizontal bar 11 and the horizontal column 21, and a fixing member 33 for fixing the connecting cover 31 and the connecting bottom shell 32. Figure 1 and Figure 6 The connecting member 3 includes a connecting cover 31 and a connecting bottom shell 32. The connecting cover 31 fixes one end of the horizontal bar 11 and the horizontal column 21 together on the outside of the horizontal bar 11 and the horizontal column 21. The connecting bottom shell 32 fixes one end of the horizontal bar 11 and the horizontal column 21 together on the inside of the horizontal bar 11 and the horizontal column 21. The connecting cover 31 and the connecting bottom shell 32 are then fixed together by the fixing member 33, thereby realizing the fixed connection of the connecting member 3 to one end of the horizontal bar 11 and the horizontal column 21.

[0046] Since the two horizontal bars 11 are arranged horizontally and the two ends of the multiple vertical bars 12 are respectively connected to the two horizontal columns 21, one horizontal bar 11 is located at the top of the multiple vertical bars 12, and the other horizontal bar 11 is located at the bottom of the multiple vertical bars 12. Similarly, one horizontal column 21 is located at the top of the multiple vertical columns 22, and the other horizontal column 21 is located at the bottom of the multiple vertical columns 22. Therefore, during the installation of this protective device, one horizontal bar 11 and the horizontal column 21 are in a high position, and the other horizontal bar 11 and the horizontal column 21 are in a low position.

[0047] In the present application, the outside of the horizontal bar 11 and the horizontal column 21 refers to the top of the horizontal bar 11 and the horizontal column 21 at the high position, and the bottom of the other horizontal bar 11 and the horizontal column 21 at the low position. The inside of the horizontal bar 11 and the horizontal column 21 refers to the bottom of the horizontal bar 11 and the horizontal column 21 at the high position, and the top of the other horizontal bar 11 and the horizontal column 21 at the low position. That is, the connecting cover 31 of a connecting member 3 is at the top of the horizontal bar 11 and the horizontal column 21 at the high position, and one end of the horizontal bar 11 and the horizontal column 21 is fixedly connected together. The connecting bottom shell 32 is at the bottom of the horizontal bar 11 and the horizontal column 21 at the high position, and one end of the horizontal bar 11 and the horizontal column 21 is fixedly connected together. The connecting cover 31 and the connecting bottom shell 32 are fixedly connected together by the fixing piece 33, thereby realizing the fixed connection of one connecting piece 3 to one horizontal bar 11 and one end of the horizontal column 21; the connecting cover 31 of the other connecting piece 3 is at the bottom of the other horizontal bar 11 and the horizontal column 21 in a low position, and the connecting bottom shell 32 is at the top of the horizontal bar 11 and the horizontal column 21 in a low position, and the connecting cover 31 and the connecting bottom shell 32 are fixedly connected together, and then the fixing piece 33 is used to fix the other connecting piece 3 to one end of the other horizontal bar 11 and the horizontal column 21.

[0048] In this embodiment, the two ends of the connecting bottom shell 32 are respectively provided with limiting grooves 321 for limiting the two adjacent vertical bars 12 and vertical columns 22, and the connecting cover 31 is provided with a receiving groove 311 for accommodating the horizontal bars 11 and the horizontal columns 21. Figure 7 、 Figure 8 and Figure 11 There are limit grooves 321 at both ends of the connecting bottom shell 32. When the connecting bottom shell 32 is clamped between the two adjacent vertical columns 12 and the two vertical columns 22 on the inner side of the horizontal column 11 and the horizontal column 21, one vertical column 12 and the vertical column 22 abut against the limit groove 321 at one end of the connecting bottom shell 32, and the other adjacent vertical column 12 and the vertical column 22 abut against the limit groove 321 at the other end of the connecting bottom shell 32, so that the connecting bottom shell 32 fixes the first additive door column 1 and the second additive door column 2; 1 is provided with a receiving groove 311. When the connecting cover 31 is inserted into the receiving groove 311 outside the horizontal bar 11 and the horizontal column 21, the connecting cover 31 wraps the two side surfaces of the horizontal bar 11 and the horizontal column 21, so that the connecting cover 31 fixes the horizontal bar 11 and the horizontal column 21. Finally, the connecting cover 31 and the connecting bottom shell 32 are fixedly connected by the fixing member 33, thereby realizing the fixed connection of the connecting member 3 to the first additive door fence 1 and the second additive door fence 2.

[0049] Since when the connecting bottom shell 32 is used to fix the first additive door fence 1 and the second additive door fence 2, a vertical bar 12 on the first additive door fence 1 and a vertical column 22 on the second additive door fence 2 are simultaneously inserted into the limiting groove 321 at one end of the connecting bottom shell 32, and another adjacent vertical bar 12 on the first additive door fence 1 and another adjacent vertical column 22 on the second additive door fence 2 are simultaneously inserted into the limiting groove 321 at the other end of the connecting bottom shell 32. Therefore, when the connecting member 3 is used to fix the first additive door fence 1 and the second additive door fence 2, a vertical bar 12 on the first additive door fence 1 and a vertical column 22 on the second additive door fence 2 overlap in the vertical direction, and another adjacent vertical bar 12 on the first additive door fence 1 and another adjacent vertical column 22 on the second additive door fence 2 overlap in the vertical direction.

[0050] Based on the structure of the connecting member 3, in this application, multiple vertical bars 12 are vertically and equidistantly arranged on the first additive door fence 1, and multiple vertical posts 22 are vertically and equidistantly arranged on the second additive door fence 2. The optimal configuration is that the distance between two adjacent vertical bars 12 is equal to the distance between two adjacent vertical posts 22. In this case, the minimum adjustable distance for the connection length between the first additive door fence 1 and the second additive door fence 2 is the distance between two adjacent vertical bars 12 or posts 22, and the adjustable unit length is also the distance between two adjacent vertical bars 12 or posts 22. Therefore, the smaller the distance between two adjacent vertical bars 12 or posts 22, the greater the adjustment range of the connection length between the first additive door fence 1 and the second additive door fence 2, and the wider the scope of application of the present protective device.

[0051] In this embodiment, a through hole 322 is provided on the connecting bottom shell 32, a first threaded hole 312 is provided on the connecting cover 31, and the fixing member 33 is a screw with one end passing through the through hole 322 and then screwed into the first threaded hole 312. Figure 6 、 Figure 7 and Figure 8 A through hole 322 is provided on the connection bottom shell 32, and a first threaded hole 312 is provided on the connection cover 31. One end of a screw passes through the through hole 322 and is screwed to the first threaded hole 312, thereby fixing the connection cover 31 and the connection bottom shell 32 together.

[0052] In the present application, the connecting bottom shell 32 and the connecting cover 31 are split structures. When the connection length of the first additive door fence 1 and the second additive door fence 2 needs to be adjusted, the overall width of the staggered first additive door fence 1 and the second additive door fence 2 is adjusted to the required width by first changing the overlapping length of one end of the first additive door fence 1 and the second additive door fence 2, and a vertical bar 12 on the first additive door fence 1 is to overlap with a vertical column 22 on the second additive door fence 2 in the vertical direction, and then the connecting bottom shell 3 is connected inside the horizontal bar 11 and the horizontal column 21. 2 is clamped between two adjacent vertical bars 12 and two adjacent vertical columns 22 that overlap with each other. The two adjacent vertical bars 12 and two adjacent vertical columns 22 are respectively abutted against the limiting grooves 321 at both ends of the connecting bottom shell 32. Then, the connecting cover 31 is inserted into the horizontal bar 11 and the horizontal column 21 at the corresponding positions outside the horizontal bar 11 and the horizontal column 21. Finally, one end of the screw passes through the through hole 322 and is screwed into the first threaded hole 312 to fix the connecting cover 31 and the connecting bottom shell 32 together, thereby completing the adjustment of the connection length of the first additive door fence 1 and the second additive door fence 2.

[0053] Therefore, when it is necessary to adjust the connection length of the first and second additive door barriers 1 and 2, the screws must first be unscrewed from the first threaded holes 312, the connection bottom shell 32 and the connection cover must be removed from the first and second additive door barriers 1 and 2, respectively, and then the overlap length of one end of the first and second additive door barriers 1 and 2 must be adjusted. In the present application, this method is used to securely connect the connection cover 31 and the connection bottom shell 32 because the screw connection facilitates the installation and removal of the connection cover 31 and the connection bottom shell 32 on the first and second additive door barriers 1 and 2, thereby making it easier to adjust the connection length of the first and second additive door barriers 1 and 2, and thus making the use of the protective device more convenient and quicker.

[0054] To further securely fasten the connection cover 31 to the connection base 32, a plurality of through holes 322 can be provided on the connection base 32, and a plurality of first threaded holes 312 can be correspondingly provided on the connection cover 31. Multiple screws can be inserted through one through hole 322 and then screwed into one of the first threaded holes 312. In this application, based on processing cost and stability requirements, two through holes 322 are provided on the connection base 32, and two first threaded holes 312 are provided on the connection cover 31. When the connection base 32 and the connection cover 31 are mounted on the horizontal rail 11 and the horizontal column 21, the optimal solution is to insert one end of the two screws through the through holes 322 on both sides of the horizontal rail 11 and the horizontal column 21, and then screwed into the first threaded holes 312.

[0055] In this embodiment, the other end of each of the two horizontal columns 21 is connected to a fixing rod 23, and the fixing rod 23 is provided with a protrusion 231 at the end away from the connection with the horizontal column 21. The second additive door frame 5 is provided with a lock for fixing or loosening the two protrusions 231. The specific effect is shown in FIG. Figure 2 and Figure 3 A lock is provided on the second additive door frame 5, which is used to fix the protrusion 231 of the fixing rod 23 away from the end connected to the cross column 21, thereby fixing the second additive door fence 2 to the second additive door frame 5, so that the protective device is in a closed state; when the lock releases the protrusion 231 of the fixing rod 23 away from the end connected to the cross column 21, the second additive door fence 2 is detached from the second additive door frame 5, so that the second additive door fence 2 and the first additive door fence 1 can be rotated inward or outward, thereby opening the protective device.

[0056] In this embodiment, the fixing rod 23 is provided with an external thread, and the other end of the cross column 21 is provided with a second threaded hole that matches the external thread. The middle of the fixing rod 23 is also provided with an adjusting nut 232, and the protrusion 231 is a circular protrusion. Figure 3 The fixing rod 23 is provided with an external thread, and the end of the crossbar 21 where it is connected to the fixing rod 23 is provided with a second threaded hole. The external thread and the second threaded hole cooperate to screw the fixing rod 23 onto the crossbar 21, thereby achieving the connection between the crossbar 21 and the fixing rod 23. This method of connecting the crossbar 21 and the fixing rod 23 is used because the overall width of the protective device can be further adjusted by adjusting the screwing depth of the fixing rod 23 in the second threaded hole.

[0057] As mentioned above, the connection length between the first and second additive gate barriers 1 and 2 is adjusted by the connector 3. The adjustable unit length is the distance between two adjacent vertical bars 12 or vertical columns 22. The smaller the distance between two adjacent vertical bars 12 or vertical columns 22, the wider the adjustment range of the connection length between the first and second additive gate barriers 1 and 2. If the vertical bars 12 of the first and second additive gate barriers 1 and 2 are arranged too closely together, the number of vertical bars 12 and vertical columns 22 will increase, thereby increasing the processing cost of the protective device. Therefore, when installing the protective device, first adjust the connection length between the first and second additive gate barriers 1 and 2 by the connector 3 so that the overall width of the protective device is close to the width of the installation space. Then, by adjusting the threaded depth of the fixing rod 23 in the second threaded hole, the overall width of the protective device can be adjusted within a small range so that the protective device can be installed just in the pre-set space.

[0058] An adjusting nut 232 is provided in the middle of the fixing rod 23 so that the screwing depth of the fixing rod 23 in the second threaded hole can be adjusted by turning the adjusting nut 232 with a wrench, thereby making the use of the protective device more convenient and labor-saving. Since the second additive door fence 2 is fixed or loosened on the second additive door frame 5 by the protrusion 231 of the fixing rod 23 away from the end connected to the crossbar 21 and cooperating with the lock on the second additive door frame 5, when adjusting the screwing depth of the fixing rod 23 in the second threaded hole, the fixing rod 23 needs to be rotated. In order to ensure that the protrusion 231 on the fixing rod 23 can cooperate with the lock on the second additive door frame 5 regardless of the position to which the fixing rod 23 is rotated, the protrusion 231 is set as a circular protrusion in the present application, so that the rotation of the fixing rod 23 does not affect the cooperation between the protrusion 231 and the lock on the second additive door frame 5.

[0059] In this embodiment, the lock includes a first lock 51 for fixing or releasing one protrusion 231, and a second lock 52 for fixing or releasing another protrusion 231. Figure 2 The lock includes a first lock buckle 51 and a second lock buckle 52. The first lock buckle 51 is used to fix or release a protrusion 231, and the second lock buckle 52 is used to fix or release another protrusion 231. When the second additive door fence 2 needs to be fixed on the second additive door frame 5, the first lock buckle 51 fixes one protrusion 231, and the second lock buckle 52 fixes the other protrusion 231, so that the lock has a better fixing effect on the second additive door fence 2 on the second additive door frame 5; when the second additive door fence 2 is to be opened on the second additive door frame 5, the first lock buckle 51 releases one protrusion 231, and the second lock buckle 52 releases the other protrusion 231, so that the second additive door fence 2 will not be opened if one of the lock buckles is accidentally touched, thereby increasing the safety of the protective device.

[0060] In this embodiment, the first lock buckle 51 is provided with a first slot 511 with an open end for inserting a protrusion 231, and a button 512 at the open end of the first slot 511 for blocking or making way for the protrusion 231 inserted in the first slot 511. The second lock buckle 52 is provided with a second slot 521 with an open end for inserting another protrusion 231, and a knob 522 at the open end of the second slot 521 for blocking or making way for the protrusion 231 inserted in the second slot 521. The first lock buckle 51 is also provided with a return spring with one end connected to the inner wall of the first lock buckle 51 and the other end connected to the button 512. For specific effects, see Figure 9 and Figure 10 The first lock buckle 51 is provided with a first slot 511 and a button 512. One end of the first slot 511 is open, and a protrusion 231 is inserted into the first slot 511 from the open end of the first slot 511. The button 512 blocks or makes way for the protrusion 231 inserted into the first slot 511 at the open end of the first slot 511.

[0061] When the button 512 is released and blocks the open end of the first slot 511, the protrusion 231 cannot be withdrawn from the first slot 511, thereby securing the protrusion 231 with the first lock 51. When the button 512 is pressed and clears the open end of the first slot 511, the protrusion 231 can be withdrawn from the open end of the first slot 511, thereby releasing the protrusion 231 with the first lock 51. A return spring is also provided in the first lock 51. One end of the return spring is connected to the inner wall of the first lock 51 and the other end is connected to the button 512. When the button 512 is pressed on the first lock 51, the return spring is compressed. When the button 512 is released, the button 512 automatically pops up under the elastic force of the return spring, making the protective device more convenient to use.

[0062] The second lock buckle 52 is provided with a second slot 521 and a knob 522. The second slot 521 is open at one end, and the other protrusion 231 is inserted into the second slot 521 from the open end of the second slot 521. The knob 522 blocks or makes way for the other protrusion 231 inserted into the second slot 521 at the open end of the second slot 521. It is foreseeable that the knob 522 is provided with a blocking portion. When the knob 522 is rotated on the second lock buckle 52 by a certain angle, the blocking portion of the knob 522 blocks the open end of the second slot 521, preventing the protrusion 231 from being withdrawn from the second slot 521, thereby allowing the second lock buckle 52 to secure the protrusion 231. When the knob 522 is rotated on the second lock buckle 52 by another angle, the blocking portion of the knob 522 makes way for the open end of the second slot 521, allowing the protrusion 231 to be withdrawn from the open end of the second slot 521, thereby allowing the second lock buckle 52 to release the protrusion 231.

[0063] In this application, the steps for opening the protective device are: first, unscrew the knob 522 from the open end of the second slot 521, then press the button 512, and finally, pull the two protrusions 231 out of the first slot 511 and the second slot 521 respectively. The steps for closing the protective device are: first, press the button 512, so that the two protrusions 231 are inserted into the first slot 511 and the second slot 521 respectively, then release the button 512, and finally, rotate the knob 522 until it blocks the open end of the second slot 521.

[0064] The reason why the first lock catch 51 and the second lock catch 52 respectively use a button 512 and a knob 522 to fix or release the two protrusions 231 in the present application is to make the use of the present protective device more convenient. If both the first lock catch 51 and the second lock catch 52 use buttons 512 to fix or release the two protrusions 231, when opening the present protective device, two buttons 512 must be pressed simultaneously with two hands, which makes it impossible for one person to open the present protective device alone, making it difficult to operate the present protective device. If both the first lock catch 51 and the second lock catch 52 use knobs 522 to fix or release the two protrusions 231, when closing the present protective device, after the two protrusions 231 are respectively inserted into the first slot 511 and the second slot 521, it is very likely that the knob 522 will be forgotten to be turned to a position that blocks the open ends of the first slot 511 and the second slot 521, resulting in both lock catches being unable to effectively fix the protrusions.

[0065] It is worth noting that, according to the directions in which the first slot 511 and the second slot 521 are respectively arranged on the first lock buckle 51 and the second lock buckle 52, there are four ways to open the protective device: the first way is that the first slot 511 and the second slot 521 are respectively arranged vertically on the first lock buckle 51 and the second lock buckle 52, with the opening ends facing upwards. In this case, the protective device is opened by lifting the second additive door fence 2 upwards, so that the two protrusions 231 are respectively pulled out from the opening ends of the first slot 511 and the second slot 521, and then the first additive door fence is opened. 1 and the second additive door fence 2 are rotated inward or outward to open the protective device. Since the first additive door fence 1 and the second additive door fence 2 are fixed by the connecting piece 3, when the second additive door fence 2 is lifted upward, the first additive door fence 1 is also lifted upward along with the second additive door fence 2. At this time, the length of the rotating shaft 42 is set to be greater than the depth of the sleeve 131, so that the sleeve 131 can not only rotate along the rotating shaft 42, but also move axially on the rotating shaft 42, so that the first additive door fence 1 and the second additive door fence 2 can be lifted upward.

[0066] The second type is that the first slot 511 and the second slot 521 are respectively vertically arranged on the first lock buckle 51 and the second lock buckle 52, with the open ends facing downward. At this time, the protective device is opened by pressing the second additive door fence 2 downward to pull the two protrusions 231 out of the open ends of the first slot 511 and the second slot 521 respectively, and then rotating the first additive door fence 1 and the second additive door fence 2 inward or outward to open the protective device. At this time, the length of the rotating shaft 42 must also be set to be greater than the depth of the sleeve 131.

[0067] The third method involves the first slot 511 and the second slot 521 being positioned horizontally on the first latch 51 and the second latch 52, respectively, with their openings facing outward. In this case, the protective device is opened by rotating the second additive door 2 outward. The fourth method involves the first slot 511 and the second slot 521 being positioned horizontally on the first latch 51 and the second latch 52, respectively, with their openings facing inward. In this case, the protective device is opened by rotating the second additive door 2 inward. In this application, the first method of opening the protective device is preferred, but in actual use, the user can select from among these methods based on their usage habits.
