Therefore, in the process of assembling the face frame 30 from top to bottom, the face frame 30, the screen frame 20 and the chassis 10 are pre-positioned by the pre-positioning structure 40, the face frame 30 is pre-positioned and guided by the pre-positioning structure 40, so that the face frame 30 can move downwards to an assembling position according to a preset route, and when the face frame 30 moves to the assembling position, the face frame 30 and the chassis 10 are fixed by the fixing structure 50, so that the face frame 30 is assembled in place. The technical scheme of the utility model can reduce the assembly difficulty of the face frame 30, so that the face frame 30 can be quickly assembled in place.
Referring to fig. 5 and 10, in one embodiment, the mounting surface 31 is provided with a downwardly extending insertion buckle 32, the bottom side of the frame 20 is provided with a first insertion hole 21 corresponding to the insertion buckle 32, the chassis 10 is provided with a second insertion hole 11 corresponding to and communicating with the first insertion hole 21, and the insertion buckle 32 sequentially penetrates through the first insertion hole 21 and the second insertion hole 11 from top to bottom to form the pre-positioning structure 40. Specifically, in the process of assembling the face frame 30 from top to bottom, the inserting buckle 32 on the assembling face 31 is firstly inserted into the first inserting hole 21 on the net frame 20, and along with the further downward movement of the face frame 30, the inserting buckle 32 is inserted into the second inserting hole 11 of the chassis 10, and through the inserting and matching of the inserting buckle 32 and the first inserting hole 21 and the second inserting hole 11, the movement of the face frame 30 in the front-back and left-right directions can be limited, and meanwhile, the movement of the face frame 30 in the up-down direction can be guided, so that the face frame 30 can continuously move downward to the assembling position along the preset track.
Referring to fig. 4 and 5, in one embodiment, the inserting buckle 32 includes a connecting section 321 extending from the assembling surface 31 toward the net frame 20, and an inserting section 322 extending downward from a side of the connecting section 321 close to the net frame 20, a position-limiting surface 3221 and a guiding surface 3222 are disposed on a side of the inserting section 322 close to the assembling surface 31, the position-limiting surface 3221 extends vertically downward, the guiding surface 3222 extends obliquely from a lower side of the position-limiting surface 3221 toward a side far away from the assembling surface 31, and a guiding mating surface 211 mating with the guiding surface 3222 and a position-limiting mating surface 212 mating with the position-limiting surface 3221 are disposed on an inner wall surface of the first inserting hole 21 downward from top.
Specifically, the guide surface 3222 and the guide engagement surface 211 may be configured as a plane or an arc surface extending obliquely in the vertical direction, and the position-limiting surface 3221 and the position-limiting engagement surface 212 may be configured as a plane or an arc surface extending in the vertical direction. When the face frame 30 is assembled from top to bottom, the guiding surface 3222 of the inserting section 322 first contacts with the guiding matching surface 211 on the upper periphery of the first inserting hole 21, under the guiding action of the guiding surface 3222 and the guiding matching surface 211, the inserting section 322 of the inserting buckle 32 can smoothly slide into the first inserting hole 21, and after the inserting buckle 32 is inserted in place, the limiting surface 3221 on the inserting section 322 is in limit-contact with the limiting matching surface 212 on the inner peripheral wall of the first inserting hole 21, so that the movement of the inserting buckle 32 in the front-back direction can be limited, and the outward movement dislocation of the face frame 30 is prevented. In order to ensure a good limiting effect, optionally, the length of the limiting part between the insert buckle 32 and the first insertion hole 21 is 2mm to 3 mm. In addition, the second insertion hole 11 on the chassis 10 can be designed as a through hole with a slightly larger size to avoid the downward movement of the insertion buckle 32 and avoid the jamming of the movement of the insertion buckle 32.
On the basis of the above embodiment, the insertion buckle 32, the first insertion hole 21 and the second insertion hole 11 are respectively provided in plurality at intervals in the left-right direction, and the insertion buckle 32, the first insertion hole 21 and the second insertion hole 11 are provided in a one-to-one correspondence manner. Through the one-to-one inserting and matching of the plurality of inserting buckles 32, the first inserting holes 21 and the second inserting holes 11, a better limiting effect can be achieved. Wherein, the number of the insert buckle 32, the first insert hole 21 and the second insert hole 11 can be set according to the length dimension of the housing assembly 100 in the left-right direction. For example, in the present embodiment, as shown in fig. 13 to 15, four insertion holes 32 are provided at intervals in the left-right direction on the mounting surface 31 of the surface frame 30, four first insertion holes 21 are provided at intervals in the left-right direction on the bottom side of the net frame 20, and four second insertion holes 11 are provided at intervals in the left-right direction on the surface of the chassis 10 opposite to the bottom side of the net frame 20. Further, the plurality of inserting buttons 32 are substantially uniformly arranged along the left-right direction, that is, the distance between any two adjacent inserting buttons 32 is the same or close, and correspondingly, the plurality of first inserting holes 21 and the plurality of second inserting holes 11 are substantially uniformly arranged along the left-right direction respectively.
In one embodiment, at least one of the first insertion holes 21 is a limiting insertion hole 21a, a single-side gap between the limiting insertion hole 21a and the corresponding eye-splice 32 in the left-right direction is 0.3mm to 1mm, and a single-side gap between the other first insertion holes 21 except the limiting insertion hole 21a and the corresponding eye-splice 32 in the left-right direction is 3mm to 6 mm. Specifically, the one-sided gap between the limiting insertion hole 21a and the corresponding insertion buckle 32 in the left-right direction is relatively small, for example, 0.3mm, 0.5mm, or 1mm, and the function is to position the face frame 30 and the screen frame 20 in the left-right direction after the face frame 30 is assembled, so that the rear side surface of the face frame 30 does not move left and right. The single-side gap between the first insertion hole 21 except the limiting insertion hole 21a and the corresponding insertion buckle 32 in the left-right direction is relatively large, for example, 3mm, 5mm, or 6mm, and the single-side gap is used for preventing the face frame 30 from being cracked due to collision when falling. For example, as shown in fig. 14, in the present embodiment, four first insertion holes 21 are provided at intervals in the left-right direction at the bottom side of the screen frame 20, wherein one of the two first insertion holes 21 located in the middle is a limiting insertion hole 21 a.
Since the side of the face frame 30 where the mounting face 31 is provided (as shown in fig. 15, the rear side wall of the face frame 30) is provided with an opening in the middle without support, the rear side wall of the face frame 30 is weak in overall strength, and in order to improve the structural strength of the rear side wall of the face frame 30, in one embodiment, the mounting face 31 is provided with flanges 33 extending in the left-right direction, and both ends of the flanges 33 extend to corners of the left and right sides of the face frame 30. Can strengthen the structural strength of face frame 30 rear side wall through setting up turn-ups 33 to the both ends of turn-ups 33 extend to the corner of face frame 30 lateral wall, can increase the intensity of face frame 30 rear side corner. It can be understood that, when the flange 33 is designed, the assembling section of the flange 33 and the net frame 20 is relatively narrower than other sections, so that the face frame 30 can be prevented from being supported and deformed too much by the net frame 20 in the assembling process, and the face frame 30 can be elastically retracted to a natural assembling state when being assembled to the bottom end of the net frame 20. Optionally, each insert buckle 32 extends downwards from the turned edge 33, and a plurality of insert buckles 32 are connected in series through the turned edge 33, so that the structural strength of the insert buckles 32 can be increased.
In addition, one side of the net frame 20 close to the assembling surface 31 is used for installing the filter screen, in order to ensure that the filter screen can move, the outer side surface of the net frame 20 is generally provided with a notch 22, and the notch 22 of the net frame 20 is easily touched by the existing surface frame 30 in the downward sliding assembling process, so that the assembling of the surface frame 30 is blocked. In order to ensure the smooth assembly of the face frame 30, as shown in fig. 14 and 15, in one embodiment, a notch 22 is formed on one side of the net frame 20 close to the assembly face 31, and the flange 33 is provided with a guide rib 34 corresponding to the notch 22, so that when the face frame 30 is assembled in a sliding manner along the net frame 20, the guide rib 34 can slide through the notch 22 to guide the movement of the face frame 30. The assembly of the face frame 30 can be guided by arranging the guide ribs 34, and in the downward sliding assembly process of the face frame 30, when the face frame 30 moves to the position of the notch 22, the guide ribs 34 can slide through the notch 22, so that the face frame 30 normally slides downward to be assembled with the bottom net frame 20 and the bottom plate 10, and the smooth assembly of the face frame 30 is ensured. In addition, the guide rib 34 extends downward from the bottom side of the flange 33, and the guide rib 34 may cooperate with the flange 33 to reinforce the structural strength of the face frame 30. For example, as shown in fig. 14 and 15, the screen frame 20 has notches 22 on left, middle and right sides near the mounting surface 31, and correspondingly, the flanges 33 have guide ribs 34 on left, middle and right sides. The guide ribs 34 on the left and right sides cooperate with the flanges 33 to enhance the structural strength of the corner of the rear side of the face frame 30.
Referring to fig. 8, fig. 11 and fig. 12, on the basis of the above embodiment, the assembling surface 31 is provided with a fixing hole 35, one side of the chassis 10 close to the assembling surface 31 is provided with a fixing buckle 12, and the fixing buckle 12 is clamped with the fixing hole 35 to form the fixing structure 50. Specifically, in the process of assembling the face frame 30 in a downward sliding manner, the inserting buckles 32 on the assembling face 31 are inserted into the first inserting holes 21 and the second inserting holes 11 to limit and guide the face frame 30, and as the face frame 30 continues to move downward to the assembling position, the fixing buckles 12 are in clamping fit with the fixing holes 35 to fix the face frame 30 with the chassis 10. Through the cooperation of the fixing buckle 12 and the fixing hole 35, the face frame 30 can be limited in the vertical direction, and the chassis 10 is prevented from protruding out of the face frame 30 after the whole machine is assembled.
Further, referring to fig. 5 and 12, the fixing buckle 12 has a guiding surface 121 extending obliquely from top to bottom toward the assembling surface 31, and the guiding surface 121 is used for guiding and matching with the bottom side of the surface frame 30. When the face frame 30 is assembled by sliding from top to bottom, the bottom side of the face frame 30 can slide downward along the guide surface 121, and the fixing hole 35 on the face frame 30 can be smoothly clamped with the fixing buckle 12 on the chassis 10 in place under the guiding action of the guide surface 121. Even if the fixing buckle 12 and the fixing hole 35 are not clamped in place, the operator only needs to apply downward pressing force (as shown by downward arrows on two sides of the top of the panel frame 30 in fig. 1), so that the fixing buckle 12 can smoothly slide into the fixing hole 35 without extending hands to the pressing buckle position of the machine chassis 10, and the assembly convenience and the assembly efficiency can be improved.
Referring to fig. 6 and 7, since the fixing hole 35 is disposed near the lower edge of the face frame 30, in order to improve the structural strength of the fixing hole 35, a flange 36 is further disposed on the periphery of the fixing hole 35.
In addition, in order to ensure the assembling reliability of the face frame 30, in the above embodiment, the fixing structures 50 are provided in two sets, two sets of the fixing structures 50 are respectively provided near the left and right sides of the face frame 30, and at least two sets of the pre-positioning structures 40 are arranged between the two sets of the fixing structures 50 at intervals in the left-right direction. For example, in one embodiment, two sets of fixing structures 50 are disposed near the left and right sides of the face frame 30 to ensure that the face frame 30 and the chassis 10 can be fixedly connected at the left and right sides, and four sets of pre-positioning structures 40 are disposed between the two sets of fixing structures 50 at intervals along the left and right direction.
Further, the distance between the fixing structure 50 and the side wall of the adjacent face frame 30 is 20mm to 25mm, and the two fixing structures 50 are disposed close to the left and right side walls of the face frame 30, respectively, as much as possible, so that the strength of the fixing structures 50 can be increased. The distance between the fixing structure 50 and the adjacent pre-positioning structure 40 in the left-right direction is 50-70 mm. The distance between the fixing structure 50 and the adjacent pre-positioning structure 40 in the left-right direction is small, the fixing structure and the adjacent pre-positioning structure 40 can interact with each other, and when the face frame 30 falls off in the transportation process, the pre-positioning structure 40 is prevented from loosening.
Referring to fig. 1 to 15, in an embodiment, the inserting buckle 32 cooperates with the first inserting hole 21 and the second inserting hole 11 to form a pre-positioning structure 40, and the fixing buckle 12 cooperates with the fixing hole 35 to form a fixing structure 50. For example, as shown in fig. 15, the rear side of the face frame 30 is provided with fixing holes 35 near the left and right side walls, respectively, and the distance between each fixing hole 35 and the adjacent side wall of the face frame 30 is 20mm to 25 mm. When the face frame 30 slides to the position where the fixing hole 35 is matched with the fixing buckle 12, because the fixing hole 35 is close to the side wall of the face frame 30, the fixing hole 35 has enough strength, the fixing hole 35 can be clamped with the fixing buckle 12 of the chassis 10, if the clamping cannot be in place, the fixing hole 35 of the face frame 30 can be clamped with the fixing buckle 12 of the chassis 10 only by pressing the position perpendicular to the fixing hole 35 at the top of the face frame 30 with a hand, and the machine chassis 10 does not need to be stretched by the hand to press the buckling position. Four inserting buckles 32 are further arranged between the two fixing holes 35 on the face frame 30, and the four inserting buckles 32 are arranged at intervals along the left-right direction. The distance between the outermost eye-splice 32 and the adjacent fixing hole 35 is small, and may be 50mm to 70 mm. When the machine falls off during transportation, the fixing buckle 12 can limit the inserting buckle 32 from falling off the outer side of the net frame 20 and the chassis 10, and the buckle position is prevented from being released. After the positions of the two outer side buckles 32 are determined, the middle buckles 32 are uniformly distributed. According to the technical scheme, the buckling positions on the face frame 30, the screen frame 20 and the chassis 10 are reasonably arranged, so that the inserting buckle 32 on the face frame 30 can be firstly led into the preset first inserting hole 21 and the preset second inserting hole 11 to form the pre-positioning structure 40, and then the fixing hole 35 on the face frame 30 is clamped and fixed with the fixing buckle 12 on the chassis 10 to form the fixing structure 50, so that the assembling operation of the face frame 30 is simple and convenient, and the assembling efficiency of the face frame 30 can be effectively improved.
