Description

Technical Field

[0001] This utility model belongs to the field of automatic assembly equipment, specifically relating to an automatic assembly equipment for steel pipes and pallets. Background Technology

[0002] In existing pallet assembly production, the assembly of steel pipes and pallets largely relies on manual operation. Workers must manually move the steel pipes one by one to the assembly holes on the side wall of the pallet, and then use tools to insert and fix them. This method has obvious drawbacks: on the one hand, manual operation is labor-intensive and inefficient, making it difficult to meet the needs of mass production; on the other hand, problems such as inaccurate alignment and insertion angle deviation are prone to occur when manually inserting steel pipes, resulting in unstable assembly quality and even damage to the pallet or steel pipes.

[0003] While some existing automated equipment can automatically feed steel pipes, it cannot adapt to pallets of different specifications (such as pallets with different assembly hole heights) and lacks effective guidance and avoidance mechanisms. During the insertion of steel pipes, excessive constraint force can easily cause jamming or equipment interference, which greatly affects assembly efficiency and quality. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an automated assembly device for steel pipes and pallets that features a simple structure, smooth assembly process, and improved assembly efficiency and quality.

[0005] The objective of this utility model can be achieved by addressing the following technical problem: providing an automatic assembly device for steel pipes and pallets, comprising a frame and a feeding mechanism, a transferring mechanism, a limiting mechanism, an adjusting mechanism, and a guiding mechanism mounted on the frame, wherein:

[0006] The feeding mechanism has a feeding channel, through which several steel pipes to be assembled can slide to their outlet end.

[0007] The limiting mechanism includes a limiting block and at least one clamping cylinder. The adjusting mechanism includes an adjusting plate, which, together with the limiting block, forms a material placement cavity. Multiple steel pipes to be assembled are stacked sequentially within the material placement cavity. The side wall of the tray has an assembly hole. The adjusting plate can drive the limiting block to move synchronously in the vertical direction, so that the side opening of the material placement cavity is aligned with the assembly hole. The clamping cylinder is mounted on the limiting block and is used to confine the steel pipes to be assembled within the material placement cavity.

[0008] The material transfer mechanism includes a pusher block, which is slidably disposed in the material placement cavity. The pusher block is used to push the steel pipe located in the material placement cavity into the assembly hole.

[0009] The guiding mechanism includes a fixed guide wheel group and a movable guide wheel group. The fixed guide wheel group and the movable guide wheel group can be movably abutted against the outer circumference of the steel pipe to guide the steel pipe into the assembly hole. The movable guide wheel group can move away from the fixed guide wheel group in a direction that is at an angle to the horizontal direction to release the constraint force of the movable guide wheel group on the steel pipe when it is inserted into the assembly.

[0010] In the aforementioned automatic assembly equipment for steel pipes and pallets, both the fixed guide wheel group and the movable guide wheel group include an L-shaped mounting plate, a horizontal rolling element, and a longitudinal rolling element. The horizontal rolling element and the longitudinal rolling element are respectively movably mounted on the two side walls of the L-shaped mounting plate and respectively movably abut against the two adjacent outer walls of the steel pipe.

[0012] An inclined bracket, on which a mounting base is provided;

[0013] A telescopic cylinder is fixed on the mounting base. The output end of the telescopic cylinder is connected to a support plate. The support plate is detachably connected to the L-shaped mounting plate in the movable guide wheel assembly.

[0014] The slide rail is mounted on the inclined support, and the slider is connected to the support plate and is movably engaged with the slide rail.

[0015] In the aforementioned automated assembly equipment for steel pipes and pallets, the adjusting mechanism includes:

[0016] A support frame, on which a screw rod support is mounted;

[0017] A lead screw and a movable block, wherein the lead screw is vertically connected to the lead screw support, and the movable block is connected to the adjusting plate and movably connected to the lead screw, so as to drive the adjusting plate to reciprocate along the axis of the lead screw;

[0018] An adjustment handle is installed at the top of the lead screw, and the adjustment handle is used to drive the lead screw to rotate.

[0019] In the above-mentioned automatic assembly equipment for steel pipes and pallets, the limiting mechanism further includes limiting posts and anti-detachment posts distributed on both sides of the top opening of the material placement cavity. The limiting posts are installed on the top wall of the adjusting plate, and the anti-detachment posts are installed on the top wall of the limiting block, and a guide slope is formed on the anti-detachment posts.

[0020] In the aforementioned automatic assembly equipment for steel pipes and pallets, there are at least two clamping cylinders, which are arranged on the limiting block with a height difference.

[0021] In the aforementioned automated assembly equipment for steel pipes and pallets, the material transfer mechanism further includes:

[0022] A fixed frame is installed at the end of the adjusting plate, and a drive motor is detachably connected to the fixed frame;

[0023] The system includes a transmission rod and a sliding block. A fixed seat is provided on the adjusting plate. The transmission rod is movably connected to the fixed seat along the length direction of the adjusting plate. The sliding block is movably connected to the transmission rod, and the sliding block is connected to the pusher block through a moving plate.

[0024] The guide rail is mounted on the adjusting plate and is arranged parallel to the axis of the transmission rod. The guide block is connected to the moving plate and is movably engaged with the guide rail.

[0025] In the aforementioned automated assembly equipment for steel pipes and pallets, the material transfer mechanism further includes:

[0026] The material transfer plate and the material transfer motor are detachably connected to the material transfer plate, and the output shaft of the material transfer motor passes through the material transfer plate and is connected to a drive gear. A rack is provided on the frame, and the drive gear is movably meshed with the rack.

[0027] The guide rail and the guide block are arranged parallel to the rack and the guide block is connected to the transfer plate and is movably engaged with the guide rail.

[0028] In the aforementioned automatic assembly equipment for steel pipes and pallets, the feeding mechanism further includes a pusher with a blanking sheet metal and a protective cover, and the feeding channel is formed on the blanking sheet metal.

[0029] In the aforementioned automatic assembly equipment for steel pipes and pallets, a support base is also installed on the adjusting plate, and a support rod is movably connected to the transfer plate on the support base.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] (1) The present invention provides an automatic assembly equipment for steel pipes and pallets. By adjusting the mechanism, the limiting block moves synchronously, so that the side opening of the material placement cavity is precisely aligned with the pallet assembly hole, which solves the problem of matching different specifications of pallets or assembly positions. In addition, the pusher block pushes the steel pipe into the assembly hole, realizing automatic assembly and improving production efficiency. Finally, the steel pipe insertion process is guided by the cooperation of the fixed guide wheel group and the moving guide wheel group, and the constraint force is released by the moving guide wheel group during insertion, which effectively avoids the phenomenon of jamming caused by excessive constraint force during the steel pipe insertion process, ensuring the assembly quality and smoothness of assembly. The overall structure is simple, the degree of automation is high, the manual labor intensity is significantly reduced, and the assembly efficiency and accuracy are improved.

[0032] (2) By relying on the limiting posts and anti-detachment posts on both sides of the top opening of the material storage cavity, the stacked steel pipes can be effectively prevented from falling out of the top opening, ensuring the safety of the feeding and assembly process. With the guide slope design on the anti-detachment post, the steel pipes can smoothly enter the material storage cavity, avoiding jamming or damage caused by sharp corners, and further improving the stability and reliability of the equipment operation.

[0033] (3) The movable connection between the support rod and the support seat provides additional support for the adjustment plate, ensuring the stability and load-bearing capacity of the adjustment plate after height adjustment, effectively preventing the adjustment plate from deforming or vibrating due to uneven force, ensuring the smoothness and accuracy of the pushing action, and further improving the assembly quality.

[0046] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0047] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0048] like Figures 1 to 5 As shown, this utility model discloses an automatic assembly equipment for steel pipe 11 and pallet 10, including a frame 2 and a feeding mechanism 3, a transferring mechanism 4, a limiting mechanism 5, an adjusting mechanism 6 and a guiding mechanism 7 mounted on the frame 2.

[0049] The feeding mechanism 3 has a feeding channel 300a, through which several steel pipes 11 to be assembled can slide to their outlet end. The limiting mechanism 5 includes a limiting block 50 and at least one clamping cylinder 51. The adjusting mechanism 6 includes an adjusting plate 60, which, together with the limiting block 50, forms a material placement cavity 500. Several steel pipes 11 to be assembled are stacked and placed in the material placement cavity 500. The side wall of the tray 10 has an assembly hole 100. The adjusting plate 60 can drive the limiting block 50 to move synchronously in the vertical direction, so that the side opening of the material placement cavity 500 is aligned with the assembly hole 100. The clamping cylinder 51 is mounted on the limiting block 50. The material transfer mechanism 4 includes a pusher block 40, which is slidably disposed in the material placement cavity 500. The pusher block 40 is used to push the steel pipe 11 located in the material placement cavity 500 into the assembly hole 100. The guide mechanism 7 includes a fixed guide wheel assembly 70 and a movable guide wheel assembly 71. The fixed guide wheel assembly 70 and the movable guide wheel assembly 71 can respectively movably abut against the outer circumference of the steel pipe 11 to guide the steel pipe 11 into the assembly hole 100. The movable guide wheel assembly 71 can move away from the fixed guide wheel assembly 70 in a direction that is at an angle to the horizontal direction to release the constraint force of the movable guide wheel assembly 71 on the steel pipe 11 when it is inserted into the assembly.

[0050] like Figure 1 As shown, the pallet 10 to be assembled can be transferred to the assembly line via a conveyor chain. Figure 1 The position shown is used to restrict the tray 10 by moving the clamping frame downwards via a clamping cylinder. Figure 1At the position shown (the structure and working principle of the conveyor chain and clamping frame are the same as those in the prior art, and will not be described in detail here), it is worth noting that at this time, the assembly hole 100 on the tray 10 is parallel to the moving direction of the pusher block 40 (collinear or parallel). At the same time, several steel pipes 11 to be assembled slide sequentially to the outlet end of the feeding channel 300a. It should be noted that a baffle plate driven by a hydraulic cylinder / pneumatic cylinder (not shown in the figure) can be set at the outlet end of the feeding channel 300a. The baffle plate temporarily stores several steel pipes 11 to be assembled in the feeding channel 300a. When the material transfer mechanism 4 drives the adjustment mechanism 6, the limiting mechanism 5, and the guiding mechanism 7 to move towards the upward feeding mechanism 3 simultaneously, the material placement cavity 500 formed by the adjustment plate 60 and the limiting block 50 (L-shaped structure design) can receive several steel pipes to be assembled. The steel pipe 11 (i.e., the baffle plate) retracts to below the feeding mechanism 3 under the drive of the telescopic cylinder 75. While ensuring that the baffle plate does not interfere with the limit block 50 and the adjusting plate 60, the top opening of the material placement cavity 500 is moved to the outlet end of the feeding channel 300a. Since the width of the material placement cavity 500 is the same as the width of the steel pipe 11, multiple steel pipes 11 sliding out from the feeding channel 300a are stacked within the material placement cavity 500. As the material transfer mechanism 4 moves again, the side opening of the material placement cavity 500 is aligned with the mounting hole 100 on the tray 10. During the alignment process, this solution can drive the adjusting plate 60 and the limiting block 50 to rise or fall synchronously through the adjusting mechanism 6, so that the side opening of the material placement cavity 500 is precisely aligned with the assembly hole 100 of the pallet 10, solving the adaptation problem of different specifications of pallets 10 or assembly positions; after the clamping cylinder 51 uniformly limits the other steel pipes 11 in the material placement cavity 500 except for the bottom steel pipe 11, the pusher block 40 can slowly enter the material placement cavity 500, pushing the bottom steel pipe 11 to move towards the side opening, so that the steel pipe 11 is aligned with the assembly hole 100 of the pallet 10. During the movement, the fixed guide wheel assembly 70 and the movable guide wheel assembly 71 are movably abutted against the outer circumference of the steel pipe 11, thereby guiding and limiting the steel pipe 11 to ensure its smooth and accurate insertion into the assembly hole 100. As a portion (which could be half, one-third, or one-quarter of the length of the steel pipe 11, adjusted according to actual needs, meaning that the steel pipe 11 will not be significantly affected by assembly fluctuations during the subsequent continuous pushing of the pusher block 40) is inserted into the assembly hole 100, the movable guide wheel assembly 71 moves along a direction at an angle to the horizontal direction (i.e., Figure 5The moving guide wheel 71 (as shown on the left, diagonally upward) moves away from the fixed guide wheel assembly 70. This action gradually releases the constraint force of the moving guide wheel assembly 71 on the steel pipe 11 during insertion, and also avoids frictional damage to the steel pipe 11 during the movement of the moving guide wheel assembly 71. Finally, with the unilateral auxiliary guidance of the fixed guide wheel, it ensures the smoothness and efficiency of the subsequent insertion and assembly of the steel pipe 11 (i.e., the remaining uninserted part of the steel pipe 11). It can be seen that this equipment not only achieves efficient and precise assembly of the steel pipe 11 and the tray 10, but also solves the problems of low precision, poor efficiency, and easy jamming in the traditional assembly process through innovative adjustment and guiding mechanisms. While reducing the intensity of manual labor, it greatly improves the assembly efficiency and precision.

[0051] Both the fixed guide wheel assembly 70 and the movable guide wheel assembly 71 include an L-shaped mounting plate 720, a horizontal rolling element 721 and a longitudinal rolling element 722. The horizontal rolling element 721 and the longitudinal rolling element 722 are respectively movably mounted on the two side walls of the L-shaped mounting plate 720 and respectively movably abut against the two adjacent outer walls of the steel pipe 11.

[0052] like Figure 2 , Figure 3 as well as Figure 5 As shown, since the steel pipe 11 to be assembled in this scheme has a square structure, the vertical sidewall layout of the L-shaped mounting plate 720 allows the rolling elements to simultaneously abut against two adjacent outer walls (such as the top and side surfaces) of the steel pipe 11, forming a stable right-angle positioning. This ensures that the axis of the steel pipe 11 is completely aligned with the center line of the assembly hole 100. In other words, the horizontal rolling elements 721 and the longitudinal rolling elements 722 on both sides of the L-shaped mounting plate 720 can stably guide and limit the steel pipe 11 from both horizontal and vertical directions. This structural design makes the contact between the guide wheel assembly and the steel pipe 11 more stable, effectively preventing the steel pipe 11 from shaking or deflecting during the guidance process. This further improves the accuracy and smoothness of the steel pipe 11 being inserted into the assembly hole 100, and reduces frictional resistance and component wear during the assembly process. Preferably, the horizontal rolling elements 721 and the longitudinal rolling elements 722 in this embodiment can be replaced by bearings or rollers or other structures.

[0053] The guiding mechanism 7 also includes: an inclined bracket 73 on which a mounting base 74 is mounted; a telescopic cylinder 75 fixed on the mounting base 74, the output end of the telescopic cylinder 75 being connected to a bearing plate 76, the bearing plate 76 being detachably connected to an L-shaped mounting plate 720 in the movable guide wheel assembly 71; a slide rail 77 and a slider 78, the slide rail 77 being mounted on the inclined bracket 73, the slider 78 being connected to the bearing plate 76 and being movably engaged with the slide rail 77.

[0054] Furthermore, such as Figure 5As shown, in this embodiment, the telescopic cylinder 75 drives the bearing plate 76 to move along the length of the slide rail 77, thereby precisely controlling the moving guide wheel assembly 71 to move closer to or away from the fixed guide wheel assembly 70. This achieves effective constraint and timely release of the adjacent side walls of the steel pipe 11. During this process, since the upper surface of the inclined bracket 73 is inclined, the guiding cooperation between the slide rail 77 and the slider 78 ensures both the smoothness and accuracy of the movement of the bearing plate 76, and also ensures that the entire moving guide wheel assembly 71 moves along the length of the slide rail 77. Figure 5 The tilting direction of the upper left avoids the longitudinal rolling element 722 in the moving guide wheel group 71 from sliding friction or positional interference with the outer wall of the steel pipe 11 during the moving away process. Therefore, the setting of the tilting bracket 73 provides a stable installation base for the entire guide mechanism 7, making the operation of the guide mechanism 7 more reliable and responsive, and able to adapt to the cycle requirements of the automated production line.

[0055] The adjusting mechanism 6 includes: a support frame 61 on which a lead screw support 62 is disposed; a lead screw 63 and a movable block 64, wherein the lead screw 63 is vertically connected to the lead screw support 62, and the movable block 64 is connected to the adjusting plate 60 and is movably connected to the lead screw 63 to drive the adjusting plate 60 to reciprocate along the axis of the lead screw 63; and an adjusting handle 65 installed at the top of the lead screw 63, which is used to drive the lead screw 63 to rotate.

[0056] For steel pipes 11 of different specifications, the positions of the assembly holes 100 in the tray 10 will inevitably change synchronously. Therefore, before assembling the steel pipe 11, this solution rotates the adjusting handle 65 to drive the lead screw 63 to rotate, which in turn drives the movable block 64 and the connected adjusting plate 60 to move linearly back and forth along the axis of the lead screw 63. This achieves precise adjustment of the height of the material placement cavity 500, ensuring the smoothness and accuracy of the subsequent insertion of the steel pipe 11 into the assembly hole 100. The threaded transmission between the lead screw 63 and the movable block 64 (equivalent to the nut structure of the lead screw 63) has the advantages of high transmission accuracy and good self-locking, which can ensure the stability of the position after adjustment and ensure that the material placement cavity 500 is precisely aligned with the assembly holes 100 of different heights in the tray 10, improving the versatility and ease of adjustment of the equipment.

[0057] The adjusting plate 60 is also equipped with a support base 601, and the support base 601 is provided with a support rod 602 that can be movably connected to the transfer plate 47.

[0058] Furthermore, such as Figure 2As shown, in this embodiment, the transfer plate 47 is provided with additional support through the movable connection (preferably a threaded connection) between the support rod 602 and the support base 601. Specifically, after the height adjustment of the adjustment plate 60 is completed by the adjustment handle 65, it can be threadedly connected to the support base 601 through the support rod 602 (the thread length of the support rod 602 is sufficient to adapt to the adjustment plate 60 at different height positions). This method enhances the stability and load-bearing capacity of the transfer plate 47 during movement, effectively prevents the transfer plate 47 from deforming or vibrating due to uneven force, ensures the smoothness and accuracy of the pushing action, and further improves the assembly quality.

[0059] The limiting mechanism 5 also includes limiting posts 52 and anti-detachment posts 53 distributed on both sides of the top opening of the material feeding cavity 500. The limiting posts 52 are installed on the top wall of the adjusting plate 60, and the anti-detachment posts 53 are installed on the top wall of the limiting block 50, and a guide slope 530 is formed on the anti-detachment posts 53.

[0060] Furthermore, such as Figure 4 As shown, when the material transfer mechanism 4 moves the material placement cavity 500 to the opening end of the feeding channel 300a, multiple steel pipes 11 can slide sequentially from the feeding channel 300a into the material placement cavity 500. During this process, the guide slope 530 on the anti-detachment column 53 provides a guiding function for the steel pipes 11 as they fall, facilitating their smooth entry into the material placement cavity 500 and avoiding jamming or damage caused by sharp edges, further improving the stability and reliability of the equipment operation. In addition, the coordinated action of the anti-detachment column 53 effectively prevents the stacked steel pipes 11 from detaching from the top opening, ensuring the safety of the feeding and assembly process. It should be noted that if the steel pipe 11 gets stuck due to sharp edges when entering the material placement cavity 500, the detection sensor (not shown in the figure) on the adjustment plate 60 can send this signal to the equipment's control system for an alarm reminder.

[0061] Since multiple steel pipes 11 (e.g., 4 steel pipes 11) need to be assembled on one side of the tray 10, the number of steel pipes 11 in the material placement cavity 500 needs to correspond to this number. After completing the receiving operation of multiple steel pipes 11, the multiple steel pipes 11 are assembled into the corresponding assembly holes 100 of the tray 10 in one go. Preferably, in this embodiment, there are at least two clamping cylinders 51, which are set on the limiting block 50 with a height difference. It is worth noting that the installation position of the clamping cylinder 51 is always higher than the steel pipe 11 at the lowest end of the material placement cavity 500. By relying on the two clamping cylinders 51 with a height difference, they can apply their respective clamping forces to the steel pipes 11 at different heights in the material placement cavity 500 (except for the bottom steel pipe 11 in the material placement cavity 500), ensuring a more stable limiting effect on the steel pipes 11. After the clamping cylinders 51 uniformly limit the other steel pipes 11 in the material placement cavity 500 except for the bottom steel pipe 11, the pusher block 40 can slowly enter the material placement cavity 500 and push the bottom steel pipe 11 to move to the side opening. At the same time, with the coordinated cooperation of the moving guide wheel group 71 and the fixed guide wheel group 70, the smoothness and stability of the steel pipe 11 when inserted into the assembly hole 100 are improved.

[0062] The material transfer mechanism 4 also includes: a fixed frame 41, installed at the end of the adjusting plate 60, with a drive motor 42 detachably connected to the fixed frame 41; a transmission rod 43 and a sliding block 44, with a fixed seat 600 provided on the adjusting plate 60, the transmission rod 43 being movably connected to the fixed seat 600 along the length direction of the adjusting plate 60; the sliding block 44 being movably connected to the transmission rod 43, and the sliding block 44 being connected to the pusher block 40 through a moving plate 440; a guide rail 45 and a guide block 46, the guide rail 45 being installed on the adjusting plate 60 and arranged parallel to the axis of the transmission rod 43, the guide block 46 being connected to the moving plate 440 and movably engaged with the guide rail 45.

[0063] like Figure 2 and Figure 3 As shown, during the assembly of steel pipe 11, drive motor 42 drives transmission rod 43 to rotate via output shaft. Since sliding block 44 and transmission rod 43 form a helical transmission pair (similar to the structure and working principle of ball screw), and sliding block 44 is restricted by guide block 46 and guide rail 45 and cannot rotate with transmission rod 43, under the rotation of transmission rod 43, sliding block 44 will move linearly back and forth along the axis of transmission rod 43, thereby realizing the movement of push block 40 through moving plate 440. When push block 40 moves into material placement cavity 500, it will push a steel pipe 11 located at the lowest end of material placement cavity 500 into the space between moving guide wheel group 71 and fixed guide wheel group 70. With the cooperation of the two, it provides guidance and limit function for steel pipe 11 to be inserted into assembly hole 100, ensuring the straightness and accuracy of steel pipe 11 movement trajectory.

[0064] The material transfer mechanism 4 also includes: a material transfer plate 47 and a material transfer motor 48. Both the support frame 61 and the material transfer motor 48 are detachably connected to the material transfer plate 47. The output shaft of the material transfer motor 48 passes through the material transfer plate 47 and is connected to a drive gear 480. A rack 20 is provided on the frame 2, and the drive gear 480 is movably meshed with the rack 20. A guide rail 490 and a guide block 491 are provided. The guide rail 490 is arranged parallel to the rack 20. The guide block 491 is connected to the material transfer plate 47 and is movably engaged with the guide rail 490.

[0065] like Figure 2 As shown, in this embodiment, the transfer motor 48 drives the gear 480 to mesh with the rack 20, thereby driving the transfer plate 47 and all its components (such as the adjusting plate 60, the limiting block 50, the fixed guide wheel group 70, the moving guide wheel group 71, etc.) to move linearly back and forth, realizing the movement of the material placement cavity 500 formed by the adjusting plate 60 and the limiting block 50 to the opening of the feeding channel 300a. During this process, the cooperation of the guide rail 490 and the guide block 491 further ensures the smoothness of the movement, making the way the material placement cavity 500 receives the steel pipe 11 more flexible and reliable, and improving the adaptability and assembly efficiency of the equipment.

[0066] The feeding mechanism 3 also includes a pusher 30 with a blanking sheet metal 300 and a protective cover 301, and a feeding channel 300a is formed on the blanking sheet metal 300. For example... Figure 2 As shown, the installation of the blanking sheet metal 300 and the protective cover 301 not only forms a stable material feeding channel 300a, but also provides good protection for the internal structure of the pusher 30, preventing dust and debris from entering and affecting the operation of the equipment, while improving the overall safety and aesthetics of the equipment. It should be noted that the pusher 30 in this solution is existing technology in the machinery industry, and its structure and working principle will not be described in detail.

[0067] It should be noted that in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly defined. The terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two elements or the interaction between two elements, unless otherwise explicitly defined.
