[0029] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:
[0030] like Figure 1 and Figure 2As shown, a two-way door opening oven mechanism 10 of an embodiment includes a housing 100, a sliding door 200, a handle 300, a latch 400 and an inner push door assembly 500, wherein the sliding door 200 is rotatably connected to the housing 100, the handle 300 is mounted on the outer side of the sliding door 200, the latch 400 is mounted on the housing 100, and the latch 400 is pivotally connected to the handle 300 so that the latch 400 is opened when the handle 300 is rotated.
[0031] Furthermore, the inner push door assembly 500 includes a push rod 510 and an elastic member 520, the push rod 510 includes a first clamping column 511, a first connecting column 512 and a second clamping column 513, the two ends of the first connecting column 512 are respectively fixedly connected to the first clamping column 511 and the second clamping column 513, the sliding door 200 is provided with an avoidance hole 210, a portion of the first connecting column 512 is located in the avoidance hole 210, the diameters of the first clamping column 511 and the second clamping column 513 are larger than the diameter of the avoidance hole 210, so that the first clamping column 511 and the second clamping column 513 are respectively located on both sides of the avoidance hole 210, thereby making the push rod 510 clamped to the sliding door 200. The elastic member 520 is sleeved on the first connecting column 512, and the elastic member 520 is elastically located between the inner side of the sliding door 200 and the first clamping column 511, and the second clamping column 513 is arranged opposite to the handle 300 so that the second clamping column 513 abuts against the handle 300 after moving.
[0032] In this embodiment, the handle 300 is installed on the outside of the sliding door 200, the bolt 400 is installed on the outside of the box body 100, and the handle 300 is pivotally connected to the bolt 400. When the handle 300 is rotated, the bolt 400 is opened, and then the sliding door 200 is opened. The diameters of the first clamping column 511 and the second clamping column 513 are larger than the diameter of the avoidance hole 210. The first connecting column 512 is located in the avoidance hole 210. The two ends of the first connecting column 512 are respectively connected to the first clamping column 511 and the second clamping column 513. The clamping column 513 is fixedly connected so that both ends of the first connection column 512 are clamped to the sliding door 200. When the staff is in the box 100, by pushing the first clamping column 511, the first clamping column 511 drives the first connection column 512 to move in the avoidance hole 210, so that the second clamping column 513 moves toward the handle 300, and when the second clamping column 513 abuts against the handle 300, the handle 300 is driven to rotate, thereby opening the latch 400 and further opening the sliding door 200. Further, the elastic member 520 is elastically connected between the first clamping column 511 and the sliding door 200. When the first clamping column 511 is pushed, the elastic member 520 is in a compressed state, and when the staff releases the first clamping column 511, the elastic member 520 stretches to reset the first clamping column 511.
[0033] In the above-mentioned two-way door opening oven mechanism 10, the sliding door 200 is rotatably connected with the box body 100, and the handle 300 is pivotally connected with the door latch 400, so that the handle 300 opens the door latch 400 and then opens the sliding door 200 when it rotates. Further, the inner push door assembly 500 is arranged on the inner side of the sliding door 200, and the diameters of the first clamping column 511 and the second clamping column 513 are larger than the diameter of the avoidance hole 210, so that the push rod 510 is clamped on the sliding door 200, and the elastic member 520 is sleeved on the first connecting column 512, and the elastic member 520 is elastically connected between the sliding door 200 and the first clamping column 511. When the staff is in the oven, the second clamping column 513 is abutted against the handle 300 by pushing the first clamping column 511, so that the handle 300 is rotated to open the door latch 400. After the staff stops pushing the first clamping column 511, the elastic member 520 resets the first clamping column 511. Specifically, the inner push door assembly 500 allows the staff to open the sliding door 200 in the oven, thereby improving the safety performance, and the inner push door assembly 500 has a relatively simple structure.
[0034] In one embodiment, the diameter of the first clamping column 511 is equal to the diameter of the second clamping column 513. In this embodiment, the diameter of the first clamping column 511 is equal to the diameter of the second clamping column 513, and the diameter of the first clamping column 511 and the diameter of the second clamping column 513 need to be larger than the diameter of the avoidance hole 210, so that the first connecting column 512 is located in the avoidance hole 210, and the first connecting column 512 is clamped to the sliding door 200. Further, in other embodiments, the diameter of the first clamping column 511 and the diameter of the second clamping column 513 may not be equal, but it is necessary to ensure that the diameter of the first clamping column 511 and the diameter of the second clamping column 513 are both larger than the diameter of the avoidance hole 210.
[0035] In one embodiment, the diameters of the first clamping column 511, the elastic member 520, the avoidance hole 210 and the first connecting column 512 decrease in sequence. In this embodiment, the diameter of the first clamping column 511 is equal to the diameter of the second clamping column 513, the first connecting column 512 is located in the avoidance hole 210, and the elastic member 520 is sleeved on the first connecting column 512, and the elastic member 520 is elastically connected between the first clamping column 511 and the sliding door 200, that is, it is necessary to ensure that the diameter of the elastic member 520 is greater than the diameter of the avoidance hole 210, so that the first connecting column 512 can move in the avoidance hole 210, and the first connecting column 512 is clamped to the sliding door 200 through the first clamping column 511 and the second clamping column 513.
[0036] In one embodiment, the first clamping column 511, the first connecting column 512 and the second clamping column 513 are an integrally formed structure. In this embodiment, the first clamping column 511, the first connecting column 512 and the second clamping column 513 are an integrally stamped structure, which makes the structure strength and compactness of the three higher.
[0037] In one embodiment, the elastic member 520 is provided with a sleeve hole, and the first connecting column 512 is located in the sleeve hole. It can be understood that the first connecting column 512 is located in the sleeve hole, so that the elastic member 520 is sleeved on the first connecting column 512, and the elastic member 520 is elastically connected between the first clamping column 511 and the sliding door 200.
[0038] In one embodiment, the length of the first connecting column 512 is greater than the length of the elastic member 520. It can be understood that when the first clamping column 511 is pushed, the first connecting column 512 moves in the avoidance hole 210 to drive the second clamping column 513 to move toward the handle 300, and the length of the first connecting column 512 is greater than the length of the elastic member 520, so that the elastic member 520 is compressed between the first clamping column 511 and the inner side of the sliding door 200, and when the force of the first clamping column 511 is canceled, the elastic member 520 stretches and resets the first clamping column 511.
[0039] In one embodiment, the elastic member 520 is a spring, so that the elastic member 520 is elastically connected between the first clamping column 511 and the sliding door 200. Of course, in other embodiments, the elastic member 520 can also be an elastic structure such as silicone or rubber.
[0040] like Figure 1 As shown, in one embodiment, an alarm button 110 is provided in the box 100. It can be understood that the alarm button 110 is electrically connected to the alarm outside the box 100, and when the staff is mistakenly locked in the box 100, the alarm button 110 is pressed to make the alarm sound.
[0041] like Figure 2 As shown, in one embodiment, the handle 300 includes a handle body 310 and a connection seat 320, the handle body 310 is rotatably connected to the connection seat 320, and the handle body 320 is pivotally connected to the door latch 400. It can be understood that the handle body 310 is rotatably connected to the connection seat 320, and when the second clamping column 513 abuts against the handle body 310, the handle body 310 rotates outward, that is, with the connection seat 320 as the rotation fulcrum, the handle body 310 is disengaged from the door latch 400, so that the handle body 310 is no longer pivotally connected to the door latch 400, and then the sliding door 200 is opened.
[0042] In another embodiment, reference Figure 2 The latch 400 includes a latch seat and a pivot roller. The latch seat is provided with a pivot slot. The pivot roller is disposed in the pivot slot. The pivot roller is rotatably connected to the latch seat. The end of the handle body 310 is movably disposed between the pivot roller and the bottom of the pivot slot. It can be understood that the handle body 310 is located in the pivot slot and abuts against the pivot roller. At this time, the sliding door is in a closed state, that is, the sliding door cannot be opened. When the handle body 310 is rotated by an external force, the pivot roller rotates relative to the latch seat, so that the handle body 310 leaves the pivot slot and no longer abuts against the pivot roller. At this time, the sliding door is in an open state, that is, the sliding door can be opened.
[0043] The present application also provides an industrial oven, comprising the two-way door opening oven mechanism 10 described in any one of the above embodiments.
[0044] Compared with the prior art, the present invention has at least the following advantages:
[0045] In the above-mentioned two-way door opening oven mechanism 10, the sliding door 200 is rotatably connected with the box body 100, and the handle 300 is pivotally connected with the door latch 400, so that the handle 300 opens the door latch 400 and then opens the sliding door 200 when it rotates. Further, the inner push door assembly 500 is arranged on the inner side of the sliding door 200, and the diameters of the first clamping column 511 and the second clamping column 513 are larger than the diameter of the avoidance hole 210, so that the push rod 510 is clamped on the sliding door 200, and the elastic member 520 is sleeved on the first connecting column 512, and the elastic member 520 is elastically connected between the sliding door 200 and the first clamping column 511. When the staff is in the oven, the second clamping column 513 is abutted against the handle 300 by pushing the first clamping column 511, so that the handle 300 is rotated to open the door latch 400. After the staff stops pushing the first clamping column 511, the elastic member 520 resets the first clamping column 511. Specifically, the inner push door assembly 500 allows the staff to open the sliding door 200 in the oven, thereby improving the safety performance, and the inner push door assembly 500 has a relatively simple structure.
[0046] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
