Description

Technical Field

[0001] The present invention relates to the technical field of towel rack assembly equipment, in particular to an assembly device for a sealed connection structure and an assembly method for a towel rack. Background Art

[0002] With the improvement of economic level, people's pursuit of quality of life is getting higher and higher. Bathroom towel racks and radiators have become popular in the north as indispensable products for decoration and home furnishing. Now the southern market is gradually rising. At present, a towel rack with a splicing structure connection method has appeared on the market. When this towel rack is assembled, an interference fit method is adopted to achieve a sealed connection between the core and the vertical and horizontal tubes of the towel rack. Compared with the traditional welding method, the production speed is faster and the production cost is relatively low.

[0003] However, the production process of this type of spliced ​​towel rack lacks corresponding assembly equipment. At present, when splicing the towel rack, it is necessary to manually splice multiple sets of vertical tubes and core bodies. After the splicing is completed, the vertical tubes and horizontal tubes connected to the core bodies still need to be spliced. Such reciprocating work is likely to cause manual fatigue, thereby reducing assembly efficiency. Moreover, because it is a manual splicing installation, the splicing force will be greater or less during the installation process, which can easily cause unstable splicing and ultimately lead to uneven product quality. Summary of the Invention

[0004] The object of the present invention is to provide an assembly device for a sealed connection structure and an assembly method for a towel rack, so as to solve the problems raised in the above background technology.

[0010] The assembly equipment of the sealing connection structure as described above: the driving component includes a trigger structure, the trigger structure includes a transverse plate slidably arranged in the chassis, the transverse plate is provided with an interlocking groove body, the interlocking groove body is slidably provided with a protrusion, and the protrusion is fixedly connected to the telescopic end of the first cylinder fixedly installed in the chassis.

[0011] The assembly equipment of the sealing connection structure as described above: the engaging groove body includes a clearance groove and a positioning groove provided on the transverse plate, and the clearance groove and the positioning groove are connected via a trigger groove.

[0012] The assembly equipment of the sealing connection structure as described above: an abutment plate is fixedly provided on the transverse plate, and an upper moving rod and a lower moving rod are respectively fixedly provided on the transverse plate and the abutment plate facing the side of the longitudinal member, and the upper moving rod and the lower moving rod are both provided with sliding members connected to the chassis, and a second tooth plate is slidably provided on the end of the upper moving rod away from the transverse plate, and a first tooth plate is fixedly provided on the end of the lower moving rod away from the abutment plate.

[0013] The assembly equipment of the sealing connection structure as described above: a trigger member is provided on the second tooth plate, and the trigger member includes a trigger rod fixedly provided on the second tooth plate, and the trigger rod cooperates with the adjustment assembly to force the second tooth plate to move further toward the transverse plate.

[0014] The assembly equipment of the sealing connection structure as described above: the adjustment component includes a guide plate fixedly arranged on the chassis, a composite groove body is opened on the guide plate, and the composite groove body includes a horizontal groove, a vertical groove, an inclined groove, a stabilizing groove and a reset groove, and the vertical groove, the inclined groove, the stabilizing groove and the reset groove are surrounded by a group of mounting blocks, and a deflection member is provided at the connection between the vertical groove and the inclined groove.

[0015] In the assembly device of the sealing connection structure as described above, the deflecting member includes a deflecting plate rotatably mounted on the mounting block, and the deflecting plate is elastically connected to the mounting block via a spring sheet.

[0016] The assembly device of the sealed connection structure as described above: the lifting assembly includes guide rods fixedly provided on the chassis, the guide rods being symmetrically provided in two groups along the width direction of the chassis, the upper plate and the lower plate being slidably provided on the guide rods, and a first spring slidably connected to the guide rods being provided between the upper plate and the lower plate;

[0017] It also includes a second cylinder fixedly disposed in the chassis, the lower plate being slidably disposed on the telescopic rod of the second cylinder, and the upper plate being fixedly connected to the end of the telescopic rod of the second cylinder;

[0018] Also proposed is an assembly device for a sealed connection structure and an assembly method for a towel rack. The assembly device using the sealed connection structure described above includes the following steps:

[0019] Step 1: In the initial state, the upper plate is away from the lower plate, and the two sets of clamping assemblies are in the open state. After the vertical pipe is placed in the plug-in block, the first cylinder is activated, driving the transverse plate and the abutment plate to pull the first tooth plate and the second tooth plate toward the transverse plate to close the clamping assembly, so that the clamping assembly on the lower plate clamps the vertical pipe;

[0020] Step 2: The second cylinder is actuated to pull the upper plate down. At this time, the position of the lower plate remains fixed. During this process, the second tooth plate, in cooperation with the trigger and the adjustment component, forces the clamping component on the upper plate to further close, thereby clamping the core body. As the upper plate descends, the clamping component drives the core body to be inserted into the vertical pipe, so that the two are sealed. Then the clamping component on the upper plate opens to clamp the vertical pipe.

[0021] Step 3: After the clamping assembly on the upper plate clamps the vertical pipe, the second cylinder pushes the upper plate up. At this time, the lower plate moves synchronously with the upper plate. Then, the two sets of clamping assemblies can drive the vertical pipe and the core to connect with the horizontal pipe installed on the chassis.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In the present invention, by setting up an assembly device and utilizing the cooperation among the driving assembly, the clamping assembly, the lifting assembly and the adjusting assembly, the fixed connection between the core body and the vertical pipe and the horizontal pipe can be completed;

[0024] The clamping assembly is provided with two groups, and the two groups of clamping assemblies are respectively arranged on the upper plate and the lower plate. When the driving assembly is actuated, the two groups of clamping assemblies are actuated synchronously, and can drive the clamping plates on the upper plate and the lower plate to close synchronously. Then, the clamping plate on the lower plate can stably clamp the vertical pipe inserted into the chassis, thereby preventing the vertical pipe from being displaced during the subsequent splicing process;

[0025] When the lifting assembly drives the upper plate to rise, the two sets of clamping assemblies work together to stably drive the vertical pipe connected with the core body to be connected with the horizontal pipe installed on the chassis.

[0026] The above-mentioned mechanical matching process has a faster production speed than the traditional manual splicing and assembly method, and the splicing strength between the core body and the vertical tube and between the core body and the horizontal tube is always the same, so the quality of the final splicing and assembly products will also be relatively consistent.

[0038] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0039] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0040] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0041] See also Figures 1-10 In an embodiment of the present invention, an assembly device for a sealed connection structure includes:

[0042] A lower plate 15 and an upper plate 16 are slidably provided on the chassis 4, and a clamping assembly is provided on each of the lower plate 15 and the upper plate 16;

[0043] For details, please refer to Figure 1 、 Figure 2 、 Figure 4A plug-in block 5 is fixedly provided on the placement table of the above-mentioned chassis 4. The plug-in block 5 is arranged in a "concave" shape, and a guide surface 501 is symmetrically provided on the front end of the plug-in block 5. When connecting the vertical pipe 1 and the chassis 4, due to the guiding effect of the guide surface 501, the vertical pipe 1 and the plug-in block 5 can be quickly connected. In particular, a non-slip silicone pad or sponge pad is provided on the contact surface between the plug-in block 5 and the vertical pipe 1. When plugging in, the deformation of the non-slip silicone pad or sponge pad can clamp and fix the vertical pipe 1, so that the vertical pipe 1 can be fixedly installed on the chassis 4, so that the subsequent clamping component can plug the core 2 into the vertical pipe 1.

[0044] A longitudinal member 9 is fixedly mounted on both the upper plate 16 and the lower plate 15. The clamping assembly is mounted on the longitudinal member 9 and includes a clamping plate 10 rotatably mounted on the longitudinal member 9. The clamping plates 10 are symmetrically arranged in two groups along the length direction of the longitudinal member 9, and a gear 11 is coaxially fixedly mounted on each group of the clamping plates 10.

[0045] Preferably, see Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 The inner wall of the clamping plate 10 is provided with a silicone pad, which has high elasticity and softness and can form a certain pressure on the contact surface, thereby increasing the friction and preventing the subsequent clamping plate 10 from slipping when clamping the core 2 or the vertical pipe 1.

[0046] The chassis 4 is also provided with a driving component and an adjusting component. When the driving component is actuated, it can force the two sets of clamping components to actuate synchronously, so that the clamping components on the lower plate 15 clamp the vertical pipe 1 placed on the chassis 4.

[0047] The chassis 4 further includes a lifting assembly, which is capable of driving the lower plate 15 and the upper plate 16 to move up and down relative to the chassis 4. During the descent of the upper plate 16, the adjusting assembly cooperates with the clamping assembly on the upper plate 16 to drive the clamping assembly on the upper plate 16 to further close, thereby clamping the core 2 and driving the core 2 to be sealed and connected to the vertical pipe 1, and then driving the clamping assembly to recover, thereby clamping the vertical pipe 1.

[0048] Preferably, see Figure 1 、 Figure 2 、 Figure 4The chassis 4 is provided with an insertion hole 102, which is used to insert the horizontal tube 3, and the inner wall of the insertion hole 102 is provided with a silicone sleeve, which can increase the friction between the horizontal tube 3 and the insertion hole 102, so that the horizontal tube 3 can be stably installed on the chassis 4, so that the vertical tube 1 and the core 2 can be connected to the horizontal tube 3 later.

[0049] For details, please refer to Figure 3 , multiple groups of docking joints 301 are equidistantly arranged on the above-mentioned horizontal tube 3, the core body 2 has a process groove, and the material is made of hard metal material, which can be carbon steel, stainless steel or other hard alloy materials, and an inner hole 101 is provided on the vertical tube 1, and an interference fit is adopted between the core body 2 and the vertical tube 1. In the process of the core body 2 squeezing the inner hole 101, the excess material squeezed out of the inner hole 101 will be squeezed into the process groove of the core body 2, forming a firm sealing connection, and then the special-shaped sealing ring 12 is sequentially inserted into the core body 2. The inner wall of the special-shaped sealing ring 12 adopts an open design, and the inner wall is hollow. When the processing length of the vertical tube 1 deviates, the sealing compression amount can be flexibly adjusted to effectively ensure the reinforced sealing effect. Multiple groups of vertical tubes 1 are connected to the horizontal tube 3, and finally a towel rack is obtained;

[0050] The above-mentioned towel rack adopts a structure and connection method that completely eliminates the welding process, making the entire towel rack production process faster and more convenient, and the front section of the core body 2 is processed with an inclination, which is used to facilitate the connection between the core body 2 and the vertical pipe 1; however, there is currently a lack of assembly equipment for towel racks composed of this special connection structure on the market. When assembling a towel rack using this connection structure, it is necessary to manually splice multiple groups of vertical pipes 1 and core bodies 2. After the splicing is completed, it is still necessary to splice the vertical pipe 1 connected to the core body 2 with the horizontal pipe 3. Such reciprocating work is likely to cause manual fatigue, thereby reducing assembly efficiency. Moreover, because it is a manual splicing installation, the splicing force will be greater or less during the installation process, which is likely to cause unstable splicing, and ultimately lead to uneven product quality.

[0051] In the present invention, the assembly equipment can assemble the vertical tube 1, the core body 2 and the horizontal tube 3 by mechanical cooperation instead of manual splicing through the mutual cooperation between the driving component, the adjustment component and the clamping component. During the mechanical cooperation process, the splicing force between the vertical tube 1, the core body 2 and the horizontal tube 3 is always the same, so that the quality of the final product is basically consistent, and its production efficiency will be relatively increased compared to manual splicing.

[0052] The drive assembly includes a trigger structure, which includes a transverse plate 17 slidably disposed within the chassis 4. The transverse plate 17 has an engaging groove, and a protrusion 1301 is slidably disposed within the engaging groove. The protrusion 1301 is fixedly connected to the telescopic end of the first cylinder 13 fixedly mounted within the chassis 4.

[0053] The engaging groove body includes a clearance groove 1701 and a positioning groove 1703 provided on the transverse plate 17 , and the clearance groove 1701 and the positioning groove 1703 are connected by a trigger groove 1702 ;

[0054] Preferably, Figure 6 、 Figure 7 As shown, in the initial state, the above-mentioned protrusion 1301 is located at the end of the stroke of the positioning groove 1703 away from the trigger groove 1702. At this time, if the position state of the telescopic end of the first cylinder 13 remains unchanged, due to the connection relationship between the positioning groove 1703 and the protrusion 1301, the position of the transverse plate 17 will be relatively fixed, thereby avoiding the transverse displacement of the transverse plate 17 due to accidental touch during the subsequent installation process (see the description below for details).

[0055] The abutment plate 20 is fixedly provided on the transverse moving plate 17, and an upper moving rod 2302 and a lower moving rod 2301 are respectively fixedly provided on the side of the transverse moving plate 17 and the abutment plate 20 facing the longitudinal member 9, and the upper moving rod 2302 and the lower moving rod 2301 are both provided with a sliding member 22 connected to the chassis 4, and the upper moving rod 2302 is slidably provided with a second toothed plate 1902 at one end away from the transverse moving plate 17, and the lower moving rod 2301 is fixedly provided with a first toothed plate 1901 at one end away from the abutment plate 20, and the first toothed plate 1901 and the second toothed plate 1902 are respectively meshed with the gears 11 provided on the lower plate 15 and the upper plate 16. When the first toothed plate 1901 and the second toothed plate 1902 slide relative to the longitudinal member 9, the gear 11 is actuated, which can drive the two sets of clamping plates 10 to perform a clamping or releasing action;

[0056] Preferably, see Figure 7 、 Figure 8 、 Figure 9 , a second spring 21 is slidably provided on the above-mentioned lower moving rod 2301 , one end of the second spring 21 abuts against a sliding member 22 slidably provided on the lower moving rod 2301 , and the other end abuts against the first tooth plate 1901 ;

[0057] Similarly, a second spring 21 is also slidably provided on the upper rod 2302 . One end of the second spring 21 abuts against a sliding member 22 slidably provided on the upper rod 2302 , and the other end abuts against the second tooth plate 1902 .

[0058] In detail, in the initial state, the second spring 21 is in a compressed state. The second spring 21 in the compressed state can push the first tooth plate 1901 and the sliding member 22 and the second tooth plate 1902 and the sliding member 22 away from each other, so that the clamping plate 10 is in an open state (such as Figure 7 、 Figure 8As shown, when the vertical pipe 1 is connected to the plug block 5, due to the connection between the protruding post 1301 and the positioning groove 1703, even if the vertical pipe 1 contacts the first tooth plate 1901 during the installation process, the first tooth plate 1901 will not be forced to move, thereby reducing the number of unnecessary deformations of the second spring 21, thereby improving the service life of the entire device;

[0059] After the vertical pipe 1 is installed, the first cylinder 13 is started. Then, the telescopic rod of the first cylinder 13 drives the protruding post 1301 to slide in the positioning groove 1703 until the protruding post 1301 contacts the triggering groove 1702. The telescopic rod that continues to move can force the protruding post 1301 to contact and squeeze the groove wall of the triggering groove 1702, and then drive the transverse plate 17 to drive the abutting plate 20 to move in the direction away from the plug-in block 5. At this time, the upward rod 2302 and the downward rod 2301 fixed on the transverse plate 17 and the abutting plate 20 can pull the second The tooth plate 1902 and the first tooth plate 1901 approach the sliding member 22. During this process, the first tooth plate 1901 and the second tooth plate 1902 respectively enter into a meshing transmission state with the gears 11 provided on the lower plate 15 and the upper plate 16, so that the two sets of clamping plates 10 on the lower plate 15 and the upper plate 16 are synchronously closed. After the protruding column 1301 is separated from the triggering groove 1702, the clamping plates 10 on the lower plate 15 are closed to the maximum extent, which can just stably clamp the vertical pipe 1, thereby preventing the vertical pipe 1 from shifting during the subsequent splicing process.

[0060] Then, the first cylinder 13 continues to move, pushing the protruding post 1301 to slide along the giving way groove 1701 until the protruding post 1301 moves to the end of the stroke where the giving way groove 1701 is away from the triggering groove 1702, and the first cylinder 13 stops moving. At this time, the cooperation between the giving way groove 1701 and the protruding post 1301 can also prevent the first tooth plate 1901 from being displaced due to accidental touch, so that the two sets of clamping plates 10 are always kept in a closed state to stably clamp the vertical pipe 1.

[0061] For further information, see Figure 9 The second tooth plate 1902 is provided with a trigger member, and the trigger member includes a trigger rod 24 fixedly provided on the second tooth plate 1902. The trigger rod 24 cooperates with the adjustment assembly to force the second tooth plate 1902 to move further toward the transverse plate 17;

[0062] The adjustment assembly includes a guide plate 8 fixedly mounted on the chassis 4. The guide plate 8 is provided with a composite slot body, which includes a horizontal slot 801, a vertical slot 802, an oblique slot 803, a stabilizing slot 804, and a reset slot 805. The vertical slot 802, the oblique slot 803, the stabilizing slot 804, and the reset slot 805 are surrounded by a group of mounting blocks 806. A deflecting member is provided at the connection between the vertical slot 802 and the oblique slot 803.

[0063] The deflecting member includes a deflecting plate 18 rotatably mounted on the mounting block 806 , and the deflecting plate 18 is elastically connected to the mounting block 806 via a spring 25 ;

[0064] Preferably, see Figure 10 The vertical groove 802, the inclined groove 803, the stabilizing groove 804 and the reset groove 805 are surrounded by a "right-angled trapezoidal" structure. In particular, the length of the horizontal groove 801 is equal to the lateral movement distance of the lateral movement plate 17;

[0065] Specifically, the end of the upward movement rod 2302 away from the transverse movement plate 17 is inserted into the second tooth plate 1902. In the initial state, the compressed second spring 21 can push the second tooth plate 1902 away from the transverse movement plate 17. At this time, the trigger rod 24 is located at the end of the horizontal slot 801 away from the vertical slot 802. The deflection plate 18 is driven by the spring 25 to remain parallel to the wall of the inclined slot 803.

[0066] In combination with the above, when the first cylinder 13 is actuated and the trigger groove 1702 cooperates with the protruding post 1301 to force the transverse plate 17 to move laterally, the second toothed plate 1902 can pull the trigger rod 24 to slide along the horizontal groove 801 until the protruding post 1301 separates from the trigger groove 1702, and the trigger rod 24 moves to engage with the vertical groove 802. When the first cylinder 13 stops actuating, the lifting assembly is actuated to pull the upper plate 16 down in the vertical direction of the chassis 4. During the descending process, the trigger rod 24 slides along the vertical groove 802, and the transverse plate 17 moves downward relative to the protruding post 1301, and the protruding post 1301 slides in the clearance groove 1701.

[0067] During this process, the clamping assembly on the upper plate 16 slowly approaches the core body 2 placed on the vertical tube 1 (because the front section of the core body 2 is processed with an inclination, the core body 2 can be stably placed in the inner hole 101 provided on the vertical tube 1). As the upper plate 16 continues to descend, the trigger rod 24 will gradually contact the deflection plate 18. Then the upper plate 16 continues to descend, causing the deflection plate 18 and the inclined groove 803 to contact and squeeze the trigger rod 24, which can force the trigger rod 24 to drive the second tooth plate 1902 to move in the direction away from the longitudinal member 9, so that the second spring 21 is further squeezed, and at the same time, the two groups of clamping plates 10 on the upper plate 16 are further closed. Until the trigger rod 24 moves to engage with the stabilizing groove 804, the clamping plates 10 on the upper plate 16 are closed to the maximum extent and can clamp the core body 2.

[0068] When the upper plate 16 is lowered further, the trigger rod 24 slides in the stable groove 804. At this time, the clamping plate 10 on the upper plate 16 maintains the clamping state and drives the core body 2 to move toward the vertical tube 1 until the trigger rod 24 moves to engage with the reset groove 805, and the core body 2 and the vertical tube 1 are sealed. Then, the second spring 21 releases its elastic potential energy, which can quickly push the trigger rod 24 to move along the reset groove 805 to engage with the vertical groove 802. During this process, the second tooth plate 1902 can move a certain distance toward the plug-in block 5, so that the two groups of clamping plates 10 on the upper plate 16 are opened to the same degree of closing as the two groups of clamping plates 10 on the lower plate 15. At this time, the upper plate 16 that continues to descend can drive the clamping plates 10 to clamp the vertical tube 1. After the trigger rod 24 moves to the end of the stroke of the vertical groove 802 away from the horizontal groove 801, the clamping components on the upper plate 16 and the lower plate 15 can complete the stable clamping of the vertical tube 1.

[0069] Then, the lifting assembly can drive the upper plate 16 and the lower plate 15 to rise. During this process, the trigger rod 24 moves along the vertical groove 802. The upper plate 16 and the lower plate 15 can, with the cooperation of the clamping assembly, drive the vertical pipe 1 connected to the core 2 to move toward the horizontal pipe 3 installed on the chassis 4, thereby connecting the core 2 with the horizontal pipe 3.

[0070] For further information, see Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 The lifting assembly includes a guide rod 6 fixedly provided on the chassis 4, and two groups of guide rods 6 are symmetrically provided along the width direction of the chassis 4. The upper plate 16 and the lower plate 15 are slidably provided on the guide rod 6, and a first spring 7 slidably connected to the guide rod 6 is provided between the upper plate 16 and the lower plate 15;

[0071] It also includes a second cylinder 14 fixedly disposed in the chassis 4, the lower plate 15 is slidably disposed on the telescopic rod of the second cylinder 14, and the upper plate 16 is fixedly connected to the end of the telescopic rod of the second cylinder 14;

[0072] Preferably, see Figure 6 In the initial state, the telescopic rod of the second cylinder 14 protrudes from the telescopic cylinder. In the initial state, the first spring 7 is in a compressed state. The first spring 7 in the compressed state pushes the lower plate 15 to fit into the baffle 601 formed on the guide rod 6, and moves the upper plate 16 away from the lower plate 15. The first cylinder 13 and the second cylinder 14 are communicatively connected by a sensing device provided in the chassis 4 (not shown in the figure). In particular, the lower plate 15 slides on the telescopic rod, and a damping sleeve is provided between the lower plate 15 and the telescopic rod.

[0073] In combination with the above, when the movement of the first cylinder 13 stops, the second cylinder 14 is actuated to drive the upper plate 16 to descend until the clamping assembly on the upper plate 16 and the clamping assembly on the lower plate 15 cooperate to stably clamp the vertical pipe 1, and the elastic potential energy stored in the first spring 7 reaches a maximum. When it is necessary to further explain, the friction between the damping sleeve and the lower plate 15 is large, which can overcome the maximum elastic potential energy stored in the first spring 7. When the upper plate 16 is subsequently driven to rise by the second cylinder 14, the lower plate 15 can rise synchronously with the upper plate 16, and under the cooperation of the two sets of clamping assemblies, the rising upper plate 16 and the lower plate 15 can drive the vertical pipe 1 connected to the core 2 to be connected with the horizontal pipe 3;

[0074] After the core body 2 is connected to the transverse tube 3, the trigger rod 24 contacts the horizontal groove 801, the protruding column 1301 is combined with the triggering groove 1702, and then the first cylinder 13 retracts. With the cooperation of the triggering groove 1702 and the protruding column 1301, the transverse plate 17 forces the first tooth plate 1901 and the second tooth plate 1902 to move toward the plug-in block 5, thereby forcing the clamping plate 10 to open and loosen the vertical tube 1. Then, after moving the horizontal tube 3 and the vertical tube 1, the next group of vertical tubes 1 and the core body 2 can be connected to the transverse tube 3. When the above-mentioned assembly equipment is used to assemble the towel rack, whether in the connection process between the core body 2 and the vertical tube 1 or the core body 2 and the transverse tube 3, the force used for splicing is always the same, so the final product quality of the towel rack will be relatively consistent.

[0075] Also proposed is an assembly device for a sealed connection structure and an assembly method for a towel rack. The assembly device using the sealed connection structure described above includes the following steps:

[0076] Step 1: In the initial state, the upper plate 16 is away from the lower plate 15, and the two sets of clamping assemblies are in the open state. After the vertical pipe 1 is placed in the plug-in block 5, the first cylinder 13 is activated, driving the transverse plate 17 and the abutment plate 20 to pull the first tooth plate 1901 and the second tooth plate 1902 toward the transverse plate 17 to close the clamping assembly, so that the clamping assembly on the lower plate 15 clamps the vertical pipe 1;

[0077] Step 2: The second cylinder 14 is actuated to pull the upper plate 16 downward. At this time, the position of the lower plate 15 remains fixed. During this process, the second toothed plate 1902, in cooperation with the trigger member and the adjustment assembly, forces the clamping assembly on the upper plate 16 to further close, thereby clamping the core 2. As the upper plate 16 descends, the clamping assembly drives the core 2 to be inserted into the vertical pipe 1, so that the two are sealed. Subsequently, the clamping assembly on the upper plate 16 opens to clamp the vertical pipe 1.

[0078] Step 3: After the clamping assembly on the upper plate 16 clamps the vertical pipe 1, the second cylinder 14 pushes the upper plate 16 upward. At this time, the lower plate 15 moves synchronously with the upper plate 16. Then, the two sets of clamping assemblies can drive the vertical pipe 1 and the core 2 to connect with the horizontal pipe 3 installed on the chassis 4.

[0079] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0080] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
