Description

TECHNICAL FIELD

[0001] The utility model relates to air conditioner technical field, specifically, a wall -hanging type air conditioner indoor unit and air conditioner. BACKGROUND

[0002] In the wall -hanging type air conditioner indoor unit, the electric control box is usually arranged at the end of the internal space of the wall -hanging type air conditioner indoor unit, for example left end or right end. But by using such setting, the overall length of the wall -hanging type air conditioner indoor unit increases, on one hand, it will lead to the material increase of the base, the middle frame and the panel of air conditioner, and promote the cost of air conditioner, on the other hand, it will also lead to the difficulty of air conditioner in indoor space and its position.

[0003] Therefore, the electric control box of part of the existing wall -hanging type air conditioner indoor unit is arranged in front of the wind wheel motor, that is, close to the side of the main indoor space. However, since the heat exchanger body of the indoor heat exchanger is connected with the refrigerant pipe, the rear wall of the electric control box is close to the refrigerant pipe, and if the air conditioner falls, the electric control box has the risk of colliding with the refrigerant pipe, thereby causing the damage of the refrigerant pipe. Especially in the drop test of the air conditioner, the collision of the electric control box with the refrigerant pipe will cause the damage of the refrigerant pipe, which is difficult to pass the drop test. SUMMARY

[0004] The first aspect of the utility model aims to provide a wall -hanging type air conditioner indoor unit to solve the technical problem of the collision of the existing electric control box with the refrigerant pipe.

[0005] The wall -hanging type air conditioner indoor unit provided by the first aspect of the utility model comprises a base, an electric control box and an indoor heat exchanger mounted on the base, the indoor heat exchanger comprises a heat exchanger body and a refrigerant pipe connected to the end of the heat exchanger body, and the heat exchanger body comprises a heat exchanger front folding part; the electric control box is located in front of the refrigerant pipe, the electric control box comprises a box body and an abutting part arranged on the box body, the abutting part is located at the upper part of the box body, and the abutting part is configured to only abut against the heat exchanger front folding part.

[0006] The wall -hanging type air conditioner indoor unit of the utility model has the following beneficial effects:

[0007] The abutting part is arranged on the box body of the electric control box, and the abutting part is configured to abut against the heat exchanger front folding part of the heat exchanger body, so that when the wall -hanging type air conditioner indoor unit falls, especially in the drop test, if the electric control box moves backward relative to the heat exchanger body, the abutting part can abut against the heat exchanger body to prevent the further movement of the electric control box relative to the heat exchanger body, so as to prevent the electric control box from colliding with the refrigerant pipe and causing the defect of the refrigerant pipe.

[0008] In an optional technical solution, the side wall of the box body facing the heat exchanger body is a first side wall, and the abutting portion protrudes from the outer side of the first side wall and has a first cavity structure inside the abutting portion and opening towards the inside of the box body.

[0009] The abutting portion is arranged on the side wall of the box body facing the heat exchanger body, which is advantageous to shorten the distance between the position where the abutting portion contacts the heat exchanger body and the box body, improve the rigidity of the abutting portion, prevent the abutting portion from being broken when colliding with the heat exchanger body, and prevent the box body from directly colliding with the refrigerant pipe. Moreover, the abutting portion is arranged to have a first cavity structure inside the abutting portion and opening towards the inside of the box body, which can form a complete ring with the peripheral wall surrounding the first cavity to bear the impact load, and the plate body is arranged at a position far from the box body to support the ring-shaped peripheral wall, further improving the rigidity of the abutting portion.

[0010] In an optional technical solution, the length direction of the abutting portion is parallel to the front fold of the heat exchanger.

[0020] By forming the first positioning surface and the second positioning surface on the opposite surfaces of the first connecting block of the motor gland, and matching the first positioning portion and / or the second positioning portion on the box body, during installation of the second connecting block of the electric control box on the first connecting block, the first positioning portion and the first positioning surface are matched first, and / or the second positioning portion and the second positioning surface are matched, then the second connecting block is continuously moved downward, the positioning precision between the first connecting block and the second connecting block is obviously improved, and the first connecting block and the second connecting block are inserted by means of concave-convex matching, so that the insertion process becomes very smooth, and the assembly efficiency is improved.

[0021] In an optional technical solution, the opposite surfaces of the first positioning portion and the second positioning portion are both provided with guide portions; the distance between the opposite guide portions gradually decreases from the free end of the first positioning portion to the root of the first positioning portion.

[0022] In this way, during installation of the electric control box on the motor gland, the first connecting block can be directly opposite the front side surface of the first connecting block by using the region with a larger width between the first positioning portion and the second positioning portion, and then gradually transition to the region with a smaller width, so that the second connecting block and the first connecting block can be matched in the horizontal direction by means of concave-convex matching, and the installation efficiency is improved.

[0047] Embodiment one:

[0048] Figure 1 A structure schematic view of the wall-mounted air conditioner indoor unit provided by the present application embodiment one is provided. Figure 2 A structure schematic view of the wall-mounted air conditioner indoor unit provided by the present application embodiment one is provided. Figure 3 A left view of the wall-mounted air conditioner indoor unit provided by the present application embodiment one is provided, in which the heat exchanger has a single-row heat exchanger inner tube. Figure 4 A left view of the wall-mounted air conditioner indoor unit provided by the present application embodiment one is provided, in which the heat exchanger has a double-row heat exchanger inner tube. Figure 5 A structure schematic view of the electric control box in the wall-mounted air conditioner indoor unit provided by the present application embodiment one is provided. Figure 6 A structure schematic view of the electric control box in the wall-mounted air conditioner indoor unit provided by the present application embodiment one is provided. Figures 1-6 As shown in the figure, the wall-mounted air conditioner indoor unit provided by the present application embodiment one comprises a base 410, an electric control box 100 and an indoor heat exchanger 300 mounted on the base 410, the indoor heat exchanger 300 comprises a heat exchanger body 320 and a refrigerant pipe 310 connected to the end of the heat exchanger body 320, the heat exchanger body 320 comprises a heat exchanger front folding part 332; the electric control box 100 is located in front of the refrigerant pipe 310, the electric control box 100 comprises a box body 130 and an abutting part 120 arranged on the box body 130, the abutting part 120 is located at the upper part of the box body 130, and the abutting part 120 is configured to abut against the heat exchanger front folding part 332.

[0049] The abutting portion 120 is arranged on the box body 130 of the electric control box 100 and configured to abut against the front folded portion 332 of the heat exchanger body 320. When the indoor unit of the wall-mounted air conditioner falls, especially when the drop test is performed, if the electric control box 100 moves backward relative to the heat exchanger body 320, the abutting portion 120 can abut against the heat exchanger body 320 to prevent the electric control box 100 from moving further relative to the heat exchanger body 320, thereby preventing the electric control box 100 from colliding with the refrigerant pipe 310 and causing defects of the refrigerant pipe 310.

[0050] In the embodiment, the indoor unit of the wall-mounted air conditioner includes a base 410. When the indoor unit of the wall-mounted air conditioner is installed indoors, a wall hanging plate (not shown) needs to be fixed on the wall, for example, nailed on the wall, and then the main unit of the indoor unit of the wall-mounted air conditioner is hung on the wall hanging plate. The base 410 is a part of the indoor unit of the wall-mounted air conditioner for being installed on the wall hanging plate. The indoor heat exchanger 300 is installed on the base 410. The electric control box 100 is located in front of the refrigerant pipe 310.

[0051] In the embodiment, the refrigerant pipe 310 includes a U-shaped pipe 311 and a refrigerant branch pipe 312. The U-shaped pipe 311 is used to connect different regions of the indoor heat exchanger 300 to reverse the flow of refrigerant in the heat exchanger body 320 of the indoor heat exchanger 300. The refrigerant branch pipe 312 is used to connect the refrigerant connection pipe 313 and different regions of the indoor heat exchanger 300. The refrigerant connection pipe 313 is connected to the outdoor unit of the air conditioner. The refrigerant branch pipe 312 is used to distribute the refrigerant flowing from the outdoor unit of the air conditioner to different regions of the indoor heat exchanger 300 or to collect the refrigerant from different regions of the indoor heat exchanger 300 to the refrigerant connection pipe 313.

[0052] In the embodiment, the heat exchanger body 320 can include a heat exchanger side wall plate 321, a heat exchanger inner pipe 322, and radiating fins (not shown). The heat exchanger inner pipe 322 is used to connect the U-shaped pipe 311 and the refrigerant branch pipe 312. The heat exchanger side wall plate 321 is arranged at the end of the heat exchanger inner pipe 322. The radiating fins are connected to the heat exchanger inner pipe 322 and arranged along the length direction of the heat exchanger inner pipe 322 to increase the contact area with the flowing air and improve the heat exchange capacity. The radiating fins are arranged parallel to the heat exchanger side wall plate 321. If the abutting portion 120 abuts against or even collides with the heat exchanger body 320 when the indoor unit of the wall-mounted air conditioner falls, the abutting portion 120 will contact the heat exchanger side wall plate 321 and the radiating fins at most. The heat exchanger side wall plate 321 and the radiating fins will be deformed. The refrigerant pipe 310 will not be directly impacted and will not cause cracks on the refrigerant pipe 310. Therefore, the normal operation of the indoor unit of the wall-mounted air conditioner will not be substantially affected, thereby ensuring that the drop test is passed.

[0053] The heat exchanger body 320 can be divided into a heat exchanger rear fold 331, a heat exchanger front fold 332 and a heat exchanger lower fold 333 along the circumference of the cross-flow fan wheel 420 of the wall-mounted air conditioner indoor unit, wherein the heat exchanger rear fold 331 is located above the rear of the cross-flow fan wheel 420, the heat exchanger front fold 332 is located above the front of the cross-flow fan wheel 420, and the heat exchanger lower fold 333 is located approximately in front of the cross-flow fan wheel 420. Figure 3 and Figure 4 That is, for the two cases of the heat exchanger body 320 having a single-row heat exchanger inner tube 322 and a double-row heat exchanger inner tube 322, it can be seen from the comparison of the two cases that if the heat exchanger body 320 with the single-row heat exchanger inner tube 322 is changed to the heat exchanger body 320 with the double-row heat exchanger inner tube 322, the front surface of the heat exchanger lower fold 333 will move forward. Figure 4 The heat exchanger inner tube 322 represented by the thicker line in FIG. 4 is a schematic of the position of the inner tube that is added to the single-row heat exchanger inner tube 322 to form the double-row heat exchanger inner tube 322. Moreover, since the abutting portion 120 is provided to prevent the rear wall of the electric control box 100 from colliding with the refrigerant pipe 310 when the wall-mounted air conditioner indoor unit falls, the distance between the abutting portion 120 and the heat exchanger body 320 in the normal state is smaller than the distance between the rear wall of the electric control box 100 and the refrigerant pipe 310, so that the collision between the rear wall of the electric control box 100 and the refrigerant pipe 310 occurs before the collision between the abutting portion 120 and the heat exchanger body 320. Therefore, the distance between the abutting portion 120 and the heat exchanger body 320 cannot be too large, and if the abutting portion 120 is provided in front of the heat exchanger lower fold 333, it is difficult to simultaneously satisfy the two cases of the single-row heat exchanger inner tube 322 and the double-row heat exchanger inner tube 322.

[0054] In the present embodiment, only the abutting portion 120 on the upper portion of the electric control box 100 abuts against the heat exchanger front fold 332, and no abutting portion 120 is provided in front of the heat exchanger lower fold 333 to abut thereagainst, so that the heat exchanger body 320 with the single-row heat exchanger inner tube 322 or the double-row heat exchanger inner tube 322 can be accommodated, and the adaptability of the electric control box 100 is improved. Since the heat exchanger front fold 332 and the heat exchanger rear fold 331 are in a substantially inverted V shape and are far apart from the cross-flow fan wheel 420, if the single-row heat exchanger inner tube is changed to the double-row heat exchanger inner tube 322, the lower surfaces of the two can be closer to the cross-flow fan wheel 420 without the upper surfaces of the two being obviously offset outward. Therefore, the provision of the abutting portion 120 on the upper portion of the electric control box 100 to abut against the heat exchanger body 320 when the wall-mounted air conditioner indoor unit falls does not result in the inability to accommodate the heat exchanger body 320 with the double-row heat exchanger inner tube 322.

[0055] In the embodiment, the box body 130 of the electric control box 100 includes a box cover 131 and a box seat 132. The abutting portion 120 is arranged on the box seat 132. It should be noted that, in the present application, the abutting portion 120 is configured to abut against the heat exchanger body 320, which means that when a drop occurs and the impact is large, the abutting portion 120 can abut against the heat exchanger body 320, and when the wall-mounted air conditioner indoor unit is in normal transportation, storage and use, no drop occurs, and the abutting portion 120 can have a gap with the heat exchanger body 320.

[0056] In addition, the electric control box 100 is also provided with a connecting lug plate 141 connected to the bottom of the front surface of the box body 130, and the connecting lug plate 141 is connected to the box body 130 through a connecting rib plate 142 to improve the connecting rigidity of the connecting lug plate 141. A through hole or notch is arranged on the connecting lug plate 141 to pass through a male threaded connecting piece such as a screw or a bolt, and the male threaded connecting piece is threadedly connected with a threaded hole column arranged on the base 410. By arranging the connecting lug plate 141 on the bottom of the box body 130 and connecting the connecting lug plate 141 with the threaded hole column on the base 410 through the male threaded connecting piece, since the electric control box 100 itself has rigidity, when the bottom of the electric control box 100 is fixed, the backward movement range of the electric control box 100 relative to the indoor heat exchanger 300 can also be reduced, so that the impact of the electric control box 100 on the heat exchanger body 320 can also be reduced.

[0057] Figure 7 A top view of the electric control box in the wall-mounted air conditioner indoor unit according to Embodiment One of the present application is shown in Figure 1 and Figures 2-7 As shown in the drawings, optionally, the side wall of the box body 130 facing the heat exchanger body 320 is a first side wall 110, the abutting portion 120 protrudes outward from the first side wall 110, and the abutting portion 120 has a first cavity structure with an opening inside the abutting portion 120 facing the inside of the box body 130.

[0058] Arranging the abutting portion 120 on the side wall of the box body 130 facing the heat exchanger body 320 is beneficial to shorten the distance between the position where the abutting portion 120 contacts the heat exchanger body 320 and the box body 130, and is beneficial to improve the rigidity of the abutting portion 120, so as to prevent the abutting portion 120 from being broken and the box body 130 from directly impacting the refrigerant pipe 310 when the abutting portion 120 collides with the heat exchanger body 320. Moreover, arranging the abutting portion 120 to have the first cavity structure with an opening inside the abutting portion 120 facing the inside of the box body 130 can form a complete ring shape with the peripheral wall surrounding the first cavity to bear the impact load, and a plate body is arranged at a position far away from the box body 130 on the peripheral wall to support the ring-shaped peripheral wall, so as to further improve the rigidity of the abutting portion 120.

[0059] In this embodiment, the electric control box 100 is arranged at the right end of the wall-mounted air conditioner indoor unit, and therefore the heat exchanger body 320 is located at the left side of the electric control box 100, that is, the side wall of the box body 130 facing the heat exchanger body 320 is the left side wall of the box body 130. That is, the first side wall 110 is the left side wall of the box body 130. Therefore, the abutting portion 120 is arranged at the left side of the box body 130.

[0060] Of course, in another implementation, the abutting portion 120 can also be arranged at the outer side of the front wall of the box body 130. For example, the abutting portion 120 can first extend forward from the outer side of the front wall of the box body 130, and then extend toward the heat exchanger body 320, so as to contact the heat exchanger body 320 when the wall-mounted air conditioner indoor unit falls, thereby preventing the refrigerant pipe 310 from being impacted.

[0061] As shown in Figure 1 , Figure 3 and Figure 4 , optionally, the length direction of the abutting portion 120 is parallel to the heat exchanger front fold portion 332.

[0062] In this way, the contact length of the abutting portion 120 and the heat exchanger front fold portion 332 can be increased, and the contact area is further increased, so as to share the impact load to a larger area, so as to prevent the abutting portion 120 from being broken and the rear wall of the electric control box 100 from directly impacting the refrigerant pipe 310 during the impact process.

[0063] As shown in Figures 3-7 , optionally, the electric control box 100 further comprises a supporting portion 150, which protrudes from the lower part of the first side wall 110 to the same height as the abutting portion 120.

[0064] By arranging the supporting portion 150 at the lower part of the first side wall 110, a plurality of supporting positions can be formed outside the first side wall 110. During the assembly of the electric control box 100, the side of the electric control box 100 can be placed on the table, and the parts inside the electric control box 100 can be assembled into the electric control box 100 from top to bottom. By arranging the supporting portion 150 to protrude from the lower part of the first side wall 110 to the same height as the abutting portion 120, the first side wall 110 can be kept horizontal when the electric control box 100 is placed on the table, and the electric control box 100 can be kept in a vertical state, thereby improving the stability of the electric control box 100 during assembly.

[0065] As shown in Figure 5 and Figure 6 , optionally, the inside of the supporting portion 150 has an opening, forming a second cavity structure facing away from the box body 130.

[0066] In this way, the mold depth for manufacturing this part of the electric control box 100 can be reduced, the production cost can be reduced, and the processing quality can be improved.

[0067] The support portion 150 can only have a circumferentially closed annular peripheral wall, and the cross section of the annular peripheral wall can be a parallelogram or a quadrangle close to a parallelogram. Since the support portion 150 is arranged on the left wall of the electric control box 100, the opening direction of the second cavity structure is leftward. The blocking portion of the second cavity structure is the first side wall 110.

[0068] Since the support portion 150 is only used to enable the box seat 132 of the electric control box 100 to be placed on the corresponding assembly table top with the opening upward, in this state, the force of the box body 130 on the support portion 150 is mainly downward pressure, and there is no excessive load in other directions. Therefore, the support portion 150 does not need to bear too much force, and therefore, the blocking portion of the second cavity can be arranged on the first side wall 110, and the first side wall 110 is used to block an opening of the second cavity structure. Therefore, the mold for manufacturing the box seat 132 does not need to be deepened beyond the first side wall 110 here, so the depth of the mold can be reduced. The support portion 150 can be formed by the mold outside the first side wall 110.

[0069] Figure 8 A left view of the electric control box in the wall-mounted air conditioner indoor unit provided in Embodiment One of the present application is shown in Figure 3 , Figure 4 and Figure 8 It is shown that the support portion 150 is optionally located below the extension line area of the abutting portion 120.

[0070] In this way, the abutting portion 120 and the support portion 150 form a triangular support area, which can provide a larger support area during assembly of the electric control box 100, and when the center of gravity of the electric control box 100 falls in the support area, the electric control box 100 can be kept stable.

[0071] Since the length direction of the abutting portion 120 is consistent with the front folded portion 332 of the heat exchanger, the triangle with the abutting portion 120 as one side and the support portion 150 as the diagonal of the side is an obtuse triangle.

[0072] Figure 9 A structure schematic view of the wall-mounted air conditioner indoor unit provided in Embodiment One of the present application is shown from another direction; Figure 10 A partial schematic view of the electric control box and the motor gland in the wall-mounted air conditioner indoor unit provided in Embodiment One of the present application is shown; Figure 11 A partial schematic view of the electric control box and the motor gland in the wall-mounted air conditioner indoor unit provided in Embodiment One of the present application is shown from another direction; as Figure 5 and Figures 7-11As shown, the wall-mounted air conditioner indoor unit comprises a motor gland 200 mounted on the base 410, the motor gland 200 has a first connecting block 210, the electric control box 100 has a second connecting block 160, the first connecting block 210 and the second connecting block 160 are connected by means of concave-convex matching; the left side surface of the first connecting block 210 is provided with a first positioning surface, and the right side surface of the first connecting block 210 is provided with a second positioning surface;

[0073] The box body 130 is provided with a first positioning portion 170 and a second positioning portion 180, and the first positioning portion 170 and the second positioning portion 180 are oppositely arranged; the first positioning portion 170 cooperates with the first positioning surface, and / or the second positioning portion 180 cooperates with the second positioning surface.

[0074] By forming the first positioning surface and the second positioning surface on the opposite surfaces of the first connecting block 210 of the motor gland 200, and cooperating with the first positioning portion 170 and / or the second positioning portion 180 on the box body 130, in the process of installing the second connecting block 160 of the electric control box 100 on the first connecting block 210, the first positioning portion 170 can be first cooperated with the first positioning surface and / or the second positioning portion 180 can be cooperated with the second positioning surface, and then the second connecting block 160 is continuously moved downward, the positioning precision between the first connecting block 210 and the second connecting block 160 is obviously improved, and the insertion of the first connecting block 210 and the second connecting block 160 by means of concave-convex matching makes the insertion process very smooth, and the assembly efficiency is improved.

[0075] In the embodiment, the first positioning portion 170 cooperates with the first positioning surface, and the second positioning portion 180 cooperates with the second positioning surface. Of course, in another implementation mode, only the first positioning portion 170 can cooperate with the first positioning surface, or only the second positioning portion 180 can cooperate with the second positioning surface. The first connecting block 210 and the second connecting block 160 can also be matched in the left-right direction.

[0076] In the embodiment, the first connecting block 210 has a recess structure, and the second connecting block 160 has a protruding structure, and the protruding structure of the second connecting block 160 is inserted into the recess structure of the first connecting block 210. Of course, in another implementation mode, the protruding structure can be arranged on the first connecting block 210, and the recess structure can be arranged on the second connecting block 160.

[0077] The second connecting block 160 comprises an insertion protrusion 161 which is arranged obliquely relative to the rear side wall of the box body 130 and gradually moves away from the rear side wall in a downward direction. The top of the first connecting block 210 is provided with a receiving cavity 213 for accommodating and matching the insertion protrusion 161, and the side of the receiving cavity 213 which is away from the rear side wall of the electric control box 100 is provided with a first notch 214 for allowing the insertion protrusion 161 to pass through.

[0078] The insertion protrusion 161 and the rear side wall of the electric control box 100 are further provided with a top connecting portion 162 and a first supporting rib plate 163. The top of the insertion protrusion 161 is connected to the rear side wall of the electric control box 100 through the top connecting portion 162, and the front lower surface of the insertion protrusion 161 is connected to the rear side wall of the electric control box 100 through the first supporting rib plate 163. Of course, the first supporting rib plate 163 can also be connected to the top connecting portion 162. The side of the receiving cavity 213 which is close to the rear side wall of the electric control box 100 is provided with a second notch 215 for allowing the first supporting rib plate 163 to be inserted.

[0079] As shown in Figure 5 , Figure 7 and Figures 9-11 Optionally, the opposite surfaces of the first positioning portion 170 and the second positioning portion 180 are provided with guide portions 173, and the distance between the opposite guide portions 173 gradually decreases from the free end of the first positioning portion 170 to the root of the first positioning portion 170.

[0080] In this way, during the installation of the electric control box 100 on the motor gland 200, the first positioning portion 170 and the second positioning portion 180 can be first aligned with the front side of the first connecting block 210 by using the region with a larger width, and then gradually transition to the region with a smaller width, so that the second connecting block 160 can be matched with the concave-convex of the first connecting block 210 in the horizontal direction, thereby improving the installation efficiency.

[0081] Specifically, in the embodiment, the first positioning portion 170 and the second positioning portion 180 not only include the matching plate 171 matched with the first positioning surface and the second positioning surface, but also include the second supporting rib plate 172 arranged on the other side of the matching plate 171. In the embodiment, the first positioning portion 170 is matched with the first positioning surface, and the second positioning portion 180 is also matched with the second positioning surface. Therefore, after the electric control box 100 is installed on the base 410 and the motor gland 200, in addition to the concave-convex structure on the top of the first connecting block 210 matched with the second connecting block 160, the first positioning portion 170 and the second positioning portion 180 also form the limiting relationship in the left and right directions with the middle and lower part of the first connecting block 210, so as to prevent the rear part of the electric control box 100 from shaking left and right relative to the first connecting block 210. The second supporting rib plate 172 can improve the rigidity of the first positioning portion 170 and the second positioning portion 180, and strengthen the fixing effect of the rear part of the electric control box 100 in the left and right directions.

[0082] As shown in Figure 10 and Figure 11 , optionally, the left side surface of the first connecting block 210 is provided with the first positioning plate 211, and the first positioning plate 211 forms the first positioning surface; the right side surface of the second connecting block 160 is provided with the second positioning plate 212, and the second positioning plate 212 forms the second positioning surface.

[0083] In this way, a larger area can be formed on the left and right side surfaces of the first connecting block 210 matched with the first positioning portion 170 and the second positioning portion 180, so that the first positioning portion 170 and the second positioning portion 180 can clamp the left and right side surfaces of the first connecting block 210, and the stability of positioning is improved.

[0084] Since the first connecting block 210 has no positioning structure on the front part of the opposite area of the first positioning plate 211 and the second positioning plate 212, although the glue reduction needs to be set on the first connecting block 210 to make the thickness of each part consistent as much as possible, the reduced part can be arranged on the opposite area of the first positioning plate 211 and the second positioning plate 212, so that the front part of the left and right side surfaces of the first connecting block 210 forms the plate structure of the first positioning plate 211 and the second positioning plate 212, so as to be matched with the first positioning portion 170 and the second positioning portion 180.
