Technical Field

[0001] This application belongs to the field of test structure technology, specifically relating to a pagoda-shaped faucet test device. Background Technology

For ease of installation, the pagoda-shaped water nozzle is fixed to the side wall of the mounting pipe, and the pagoda-shaped water nozzle and the mounting pipe are integrally formed. The mounting pipe is installed on the coolant distribution pipe.

[0003] During the mass production of pagoda-shaped faucets, it is necessary to randomly inspect a portion of the faucets and conduct radial load tests and axial tensile tests on them to check whether they meet the requirements.

[0004] In the existing technology, there are two sets of radial test fixtures and axial test fixtures, and the fixtures need to be replaced in order to meet the requirements of radial and axial tests. Utility Model Content

[0005] This application provides a pagoda-shaped faucet testing device, which aims to solve the problem in the prior art that the fixture needs to be changed to complete radial and axial tests.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A testing device for pagoda-shaped faucets is provided, comprising:

[0008] A workbench, wherein the workbench is provided with a lifting drive mechanism, the lifting drive mechanism having a lifting end;

[0009] A column, the bottom end of which is connected to the workbench; the outer peripheral wall of the column has a crossbar;

[0010] Two clamping blocks each have a semi-circular groove for clamping the pagoda-shaped water nozzle, and the two clamping blocks are fixed by a fixing structure; each clamping block has an insertion hole, the axis of which is perpendicular to the axis of the semi-circular groove and intersects with the axis; the lifting end has a through hole that can be aligned with the insertion hole and can be fixed by a pin.

[0011] When the installation pipe is inserted into the column, the pagoda faucet is in a horizontal position, and the clamping block provides radial load to the pagoda faucet under the pressure of the lifting end; when the installation pipe is inserted into the crossbar, the pagoda faucet is in a vertical position, and the lifting end is fixed to the clamping block by a pin to provide axial tension to the pagoda faucet.

[0012] In one possible implementation, both clamping blocks have sockets that are aligned with each other.

[0013] The lifting end is connected to two baffles, each of which has a through hole aligned with the insertion hole; when the through holes on the two baffles are aligned with the insertion hole on the clamping block, the clamping block is located between the two baffles, and the two baffles and the clamping block are connected by a pin.

[0014] In one possible implementation, one of the clamping blocks has a through hole and the other clamping block has a threaded hole; the fixing structure includes a fixing bolt, the threaded end of which passes through the through hole on the clamping block and engages with the other clamping block to fix the two clamping blocks.

[0015] In one possible implementation, the clamping block has two sets of threaded holes, which are located on both sides of the pagoda-shaped water tap.

[0016] In one possible implementation, the semi-circular groove has a straight section and a tapered section, and the connection between the straight section and the tapered section is transitioned by an arc surface;

[0017] The free end of the pagoda-shaped water nozzle is a conical structure, and the diameter of the large end of the conical structure is larger than the diameter of the pagoda-shaped water nozzle; the conical section of the semi-arc groove has the same taper as the conical structure, and the arc surface can contact the large end of the conical structure to axially limit the pagoda-shaped water nozzle.

[0018] In one possible implementation, the crossbar on the column is replaced with a U-shaped plate, which has through holes on opposite sides for mounting pipes to pass through.

[0019] The bottom plate of the U-shaped plate is connected to the bottom end of the column, and the top end of the column is located below the through hole of the U-shaped plate.

[0020] In one possible implementation, the base plate of the U-shaped plate is fixed on the workbench, and the column is slidably engaged with the base plate of the U-shaped plate so that the top of the column slides below the through hole of the U-shaped plate.

[0021] The workbench has a receiving cavity for inserting the column, and the bottom plate of the U-shaped plate has a through hole for the column to pass through; when the column slides upward to its maximum position, the column and the bottom plate of the U-shaped plate are fixed together by a connecting structure.

[0022] In one possible implementation, the connection structure includes a plurality of connecting rods, and the outer peripheral wall of the column has connecting holes corresponding to the connecting rods one by one;

[0023] When one end of the connecting rod is inserted into the connecting hole, the other end of the connecting rod is located on the bottom plate of the U-shaped plate to support the column.

[0024] In one possible implementation, the through holes on both sides of the U-shaped plate are strip-shaped holes, so that the two ends of the mounting tube are respectively located in the through holes on both sides of the U-shaped plate.

[0025] In one possible implementation, the lifting drive mechanism includes:

[0026] A support frame is connected to the workbench; the top of the support frame has a bent portion, which is located directly above the column;

[0027] A hydraulic cylinder is connected to the bent portion.

[0028] When conducting a radial load test on a pagoda-shaped faucet, two clamping blocks are used to hold the faucet, and the positions of the two clamping blocks are fixed by a fixing structure. The mounting pipe is then placed on the column, and the faucet is placed horizontally. The lifting end of the lifting drive mechanism presses down on the clamping blocks to provide a radial load to the faucet, thus completing the radial test of the faucet.

[0029] When conducting an axial load test on a pagoda-shaped faucet, two clamping blocks are used to hold another pagoda-shaped faucet, and the positions of the two clamping blocks are fixed by a fixing structure. Then, the mounting tube is placed on the crossbar, and the pagoda-shaped faucet is rotated to a vertical position. The lifting end moves downward to a position aligned with the insertion hole, and then the clamping blocks and the lifting end are fixed together by inserting a pin into the through hole and insertion hole of the lifting end. The upward movement of the lifting end provides tension to the clamping blocks, thereby providing an axial load to the pagoda-shaped faucet, and finally completing the axial test of the pagoda-shaped faucet.

[0030] The present application provides a pagoda-shaped faucet testing device. Compared with the prior art, the above-mentioned settings of the present application eliminate the need to change the fixture when performing axial and radial tests on the pagoda-shaped faucet, thus saving the time of changing the fixture and improving efficiency.

[0043] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0044] Please refer to the following: Figures 1 to 11This application describes a pagoda-shaped faucet testing device. The device includes a workbench 1, a column 2, and two clamping blocks 3. The workbench 1 is equipped with a lifting drive mechanism 4, which has a lifting end. The bottom end of the column 2 is connected to the workbench 1. The outer peripheral wall of the column 2 has a crossbar 21. Each of the two clamping blocks 3 has a semi-circular groove 31 for clamping the pagoda-shaped faucet, and the two clamping blocks 3 are fixed by a fixing structure. Each clamping block 3 has an insertion hole 32, the axis of which is aligned with the semi-circular groove 31. The axes are perpendicular and intersecting; the lifting end has a through hole that can be aligned with the insertion hole 32 and can be fixed by the pin 33; when the mounting pipe 5 is inserted into the column 2, the pagoda water nozzle 6 is in a horizontal state, and the clamping block 3 provides radial load to the pagoda water nozzle 6 under the pressure of the lifting end; when the mounting pipe 5 is inserted into the crossbar 21, the pagoda water nozzle 6 is in a vertical state, and the lifting end is fixed to the clamping block 3 by the pin 33 to provide axial tension to the pagoda water nozzle 6.

[0045] The present application provides a testing device for a pagoda-shaped water tap 6. Compared with the prior art, the above-mentioned setting of the present application eliminates the need to change the fixture when performing axial and radial tests on the pagoda-shaped water tap 6, thus saving the time of changing the fixture and improving efficiency.

[0046] Since the axis of the through hole on the clamping block 3 is perpendicular to the axis of the semi-arc groove 31, and the axis of the through hole on the clamping block 3 intersects with the axis of the semi-arc groove 31, when an upward pulling force is applied to the clamping block 3, the direction of the pulling force can be along the axis of the pagoda water nozzle 6.

[0047] It should be noted that when applying radial load to the pagoda-shaped water nozzle 6, 600N is first applied to the clamping block 3 and held for 10 seconds; then the pressure is gradually increased until the pagoda-shaped water nozzle 6 breaks. When applying axial load to the pagoda-shaped water nozzle 6, 200N is first applied to the clamping block 3 and held for 10 seconds; then the pressure is gradually increased until it breaks. Since this is a destructive test, one pagoda-shaped water nozzle 6 is used for each of the radial and axial load tests; that is, the same pagoda-shaped water nozzle 6 will not be tested twice. The testing device in this application does not require changing the clamps, but the pagoda-shaped water nozzle 6 needs to be replaced when switching between radial and axial tests.

[0048] In some embodiments, such as Figures 1 to 11As shown, both clamping blocks 3 have insertion holes 32, and the insertion holes 32 are aligned with each other; two baffles 7 are connected to the lifting end, and both baffles 7 have through holes aligned with the insertion holes 32; when the through holes on the two baffles 7 are aligned with the insertion holes 32 on the clamping blocks 3, the clamping blocks 3 are located between the two baffles 7, and the two baffles 7 are connected to the clamping blocks 3 by a pin 33. A pressure plate 71 is fixedly connected between the two baffles 7, and the pressure plate 71 can apply a clamping force to the clamping blocks when the pagoda faucet 6 is subjected to a radial test.

[0049] When conducting a radial load test on the pagoda faucet 6, after the mounting pipe 5 is fitted onto the column 2, the pagoda faucet 6 is in a horizontal state. At this time, one of the baffles 7 can contact the clamping block 3 after moving downward. As the baffle 7 continues to move downward, it can provide a radial load to the clamping block 3, thereby providing a radial load to the pagoda faucet 6.

[0050] When conducting an axial test on the pagoda-shaped water nozzle 6, the mounting sleeve is fitted onto the crossbar 21, and the pagoda-shaped water nozzle 6 is rotated to a vertically upward position. When the baffle 7 moves downward to align with the insertion hole 32 of the clamping block 3, the clamping block 3 is located between the two baffles 7. At this time, the pin 33 passes through the through hole on the baffle 7 and the insertion hole 32 on the clamping block 3. During the upward movement of the baffle 7, it can provide an upward pulling force to the clamping block 3, thereby providing an upward pulling force to the pagoda-shaped water nozzle 6.

[0051] In some embodiments, such as Figures 1 to 11 As shown, one of the clamping blocks 3 has a through hole, and the other clamping block 3 has a threaded hole; the fixing structure includes a fixing bolt 34, the threaded end of the fixing bolt 34 passes through the through hole on the clamping block 3 and is threadedly engaged with the other clamping block 3 to fix the two clamping blocks 3; the clamping blocks 3 have two sets of threaded holes, which are located on both sides of the pagoda faucet 6.

[0052] When clamping the pagoda water nozzle 6 with the two clamping blocks 3, first loosen the fixing bolt 34 so that the distance between the semi-circular grooves 31 on the two clamping blocks 3 is greater than the diameter of the pagoda water nozzle 6, and then insert the pagoda water nozzle 6 between the two semi-circular grooves 31; by tightening the fixing bolt 34, the two clamping blocks 3 can clamp the pagoda water nozzle 6.

[0053] To improve connection stability, each set can have two threaded holes, that is, a total of four threaded holes are set. The two clamping blocks 3 are connected by four fixing bolts 34, which can fix the pagoda water nozzle 6 between the two clamping blocks 3.

[0054] In some embodiments, such as Figures 1 to 11As shown, the semi-circular groove 31 has a straight section 311 and a conical section 312, and the connection between the straight section 311 and the conical section 312 is transitioned by an arc surface 313; wherein, the free end of the pagoda water nozzle 6 is a conical structure 61, and the diameter of the large end of the conical structure 61 is larger than the diameter of the pagoda water nozzle 6; the conical section 312 of the semi-circular groove 31 has the same taper as the conical structure 61, and the arc surface 313 can contact the large end of the conical structure 61 to axially limit the pagoda water nozzle 6.

[0055] After placing the conical structure 61 of the pagoda-shaped water nozzle 6 into the two semi-circular grooves 31, the positions of the two clamping blocks 3 are fixed by the fixing bolts 34. At this time, the large end of the conical structure 61 is located at the arc surface 313, which can play an axial limiting role on the large end of the conical structure 61 and reduce the situation where the pagoda-shaped water nozzle 6 separates from the clamping blocks 3.

[0056] It should be noted that since the diameter of the arc surface 313 is larger than the diameter of the straight section 311, the arc surface 313 can play an axial limiting role on the large end of the conical structure 61.

[0057] In some embodiments, such as Figures 1 to 11 As shown, the crossbar 21 on the column 2 is replaced by a U-shaped plate 22. The U-shaped plate 22 has through holes on both sides for the installation tube 5 to pass through. The bottom plate of the U-shaped plate 22 is connected to the bottom end of the column 2, and the top end of the column 2 is located below the through holes of the U-shaped plate 22. The through holes on both sides of the U-shaped plate 22 are strip holes 221, so that the two ends of the installation tube 5 are located in the through holes on both sides of the U-shaped plate 22.

[0058] It should be noted that when using the U-shaped plate 22, two baffles 7 are connected to the lifting end of the lifting drive mechanism 4, and a clearance space is formed between the two baffles 7; when conducting axial tests on the pagoda water nozzle 6, interference between the lifting end and the top of the column 2 can be avoided.

[0059] The column 2 and the U-shaped plate 22 can be either slidably connected or fixedly connected. When the column 2 and the U-shaped plate 22 are fixedly connected, the through hole on the U-shaped plate 22 is located above the top of the column 2 to ensure that the mounting tube 5 can be inserted and mated with the U-shaped plate 22.

[0060] When the U-shaped plate 22 and the column 2 are slidably connected, the bottom plate of the U-shaped plate 22 is fixed on the workbench 1, and the column 2 and the bottom plate of the U-shaped plate 22 are slidably engaged so that the top of the column 2 slides below the through hole of the U-shaped plate 22; wherein, the workbench 1 has a receiving cavity for inserting the column 2, and the bottom plate of the U-shaped plate 22 has a through hole for the column 2 to pass through; when the column 2 slides upward to the maximum position, the column 2 and the bottom plate of the U-shaped plate 22 are fixed by a connecting structure; the receiving cavity is located at the bottom of the workbench 1, and the receiving cavity is composed of several L-shaped rods 11, the top of the L-shaped rods 11 is fixed to the bottom of the workbench 1, and the receiving cavity is formed between the several L-shaped rods 11 and the bottom of the workbench 1.

[0061] By setting a receiving cavity on the workbench 1, when it is necessary to conduct an axial test on the pagoda faucet 6, the connecting structure is separated from the column 2. The column 2 slides into the receiving cavity under the action of gravity, so that the top of the column 2 is located below the strip hole 221. At this time, the mounting tube 5 can be placed between the two sides of the U-shaped plate 22, and the two ends of the mounting tube 5 are respectively inserted and matched with the two sides of the U-shaped plate 22.

[0062] In some embodiments, such as Figures 1 to 11 As shown, the connecting structure includes several connecting rods 23, and the outer peripheral wall of the column 2 has connecting holes 24 corresponding to the connecting rods 23 one by one; wherein, when one end of the connecting rod 23 is inserted into the connecting hole 24, the other end of the connecting rod 23 is located on the bottom plate of the U-shaped plate 22 to support the column 2.

[0063] By setting several connecting holes 24 on the side wall of the column 2, when the pagoda faucet 6 is tested radially, the column 2 is slid upward from the accommodating cavity to the maximum position, and the connecting rod 23 is inserted into the connecting hole 24 to support the column 2; the pagoda faucet 6 can be tested radially by inserting the installation tube 5 into the column 2.

[0064] In some embodiments, such as Figures 1 to 11 As shown, the lifting drive mechanism 4 includes a support frame 41 and a hydraulic cylinder 42; the support frame 41 is connected to the worktable 1; the top of the support frame 41 has a bent portion 411, which is located directly above the column 2; the hydraulic cylinder 42 is connected to the bent portion 411.

[0065] The support frame 41 can be a portal frame. The hydraulic cylinder 42 is fixed on the bending part 411. The piston rod of the hydraulic cylinder 42 passes through the bending part 411, and a horizontal plate 43 is fixedly provided at the end of the piston rod of the hydraulic cylinder 42. Two baffles 7 are fixedly provided at the bottom of the horizontal plate 43.

[0066] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
