Description

Technical Field

[0001] This utility model relates to the field of ground spring testing technology, and in particular to a ground spring testing assembly. Background Technology

[0002] A floor spring is a hydraulic door closer suitable for two-way doors. It has good elasticity and durability, and can withstand long-term external forces without deformation or damage, maintaining the stability and safety of the building structure.

[0003] Durability testing of floor springs can evaluate their performance during repeated loading and unloading processes, especially their fatigue life after prolonged use. This is crucial for ensuring the reliability and safety of floor springs in actual working environments. If a floor spring suddenly breaks during operation, it may lead to serious accidents. Durability testing can help predict and prevent such situations from occurring. Durability testing helps to identify design or manufacturing defects in advance, improve product performance, reduce maintenance costs, and enhance user experience.

[0004] Since the function of a floor spring is bidirectional, most existing floor spring test assemblies can only drive the test door frame on the floor spring to open in one direction during testing, resulting in low test reliability. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a ground spring test assembly that can perform a bidirectional oscillation durability test on the ground spring, thereby improving the reliability of the test.

[0006] To solve the above-mentioned technical problems, this utility model provides a floor spring testing assembly, including a frame, a test gate frame, a swing device, and a detection device. The frame is provided with a clamping mechanism for holding the floor spring. The lower side of the test gate frame has a test hole for connecting to the floor spring. The upper side of the test gate frame has a rotating rod for rotatably connecting to the frame and coaxially arranged with the test hole. A driving component is provided in the middle of the upper side of the test gate frame. The swing device includes a swing motor and a swing arm horizontally installed at the output end of the swing motor for swaying the driving component back and forth. The rotation axis of the swing arm is located directly in front of the rotating rod. The detection device includes a controller installed on the frame and two first photoelectric switches installed on the frame at left and right intervals for detecting the outside of the swing arm. The swing motor and the first photoelectric switches are both communicatively connected to the controller.

[0007] As an improvement to the above scheme, the distance between the rotating rod and the driving component is a, the distance between the rotating rod and the rotation axis of the pendulum is b, the distance between the rotating rod and the outside of the test door frame is c, and the distance between the rotation axis of the pendulum and the outer end of the pendulum is d. Then ba < d < ca.

[0008] As an improvement to the above solution, the driving component is a roller rotatably connected to the upper center of the test door frame. The rotation axis of the roller is perpendicular to the horizontal plane, and the outer diameter of the roller is greater than the thickness of the test door frame.

[0009] As an improvement to the above solution, the swing rod is a round rod with a hemispherical outer end.

[0010] As an improvement to the above solution, the output end of the swing motor is provided with a through hole that is horizontally slidably connected to the swing arm, and the output end of the swing motor is provided with a threaded through hole that communicates with the through hole. The axis of the threaded through hole is perpendicular to the axis of the through hole, and the threaded through hole is threadedly connected with a locking bolt for abutting against the swing arm.

[0011] As an improvement to the above solution, the frame is provided with two elongated through holes extending forward and backward. The two first photoelectric switches pass through the elongated through holes one to one, and the first photoelectric switches are threadedly connected to locking nuts at the upper and lower ends of the frame that abut against each other.

[0012] As an improvement to the above solution, the detection device further includes a second photoelectric switch mounted on the frame and positioned directly in front of the pivot axis of the swing arm, used for detecting the outer side of the upper side of the test gate frame. The second photoelectric switch is communicatively connected to the controller.

[0013] As an improvement to the above solution, the floor spring testing assembly of this utility model also includes a digital display instrument mounted on the frame and connected to the controller.

[0014] As an improvement to the above solution, the clamping mechanism includes two sets of positioning plates spaced apart on the left and right, and the positioning plates are threadedly connected with positioning bolts for abutting against the left or right side of the floor spring.

[0015] Implementing this utility model has the following beneficial effects:

[0016] The floor spring testing assembly of this utility model, through the cooperation of a frame, a test gate frame, a swing device, and a detection device, can drive the test gate frame connected to the floor spring to swing back and forth in both directions and count, thereby realizing a durability test of the floor spring by bidirectional swing and improving the reliability of the test.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to facilitate a clearer understanding of the technical concept claimed by the present invention. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit the present invention.

[0031] like Figures 1 to 8As shown in the figure, a floor spring testing assembly in this embodiment of the present invention includes a frame 100, a test door frame 200, a swing device 300, and a testing device. The frame 100 is provided with a clamping mechanism 110 for clamping the floor spring. The test door frame 200 has a test hole 210 for connecting with the floor spring inside its lower side. The test door frame 200 has a rotating rod 220 on its upper side for rotatably connecting with the frame 100 and coaxially arranged with the test hole 210. In fact, the frame 100 is provided with a connecting round hole, and the test door frame 200 is rotatably connected to the connecting round hole through the rotating rod 220, and can also move up and down relative to the frame 100 to facilitate lifting the test door frame 200 and provide operating space for the installation of the floor spring; the clamping mechanism 110, the clamping mechanism can be a cylinder or a manual clamp with a positioning seat and other components. When the floor spring to be tested is placed in the corresponding position on the frame 100, the clamping mechanism 110 is operated to clamp the floor spring to be tested, and then the test door frame 200 is lowered and the top axis of the floor spring is connected to the test hole 210 on the lower side of the door frame, so that the test door frame 200 can swing back and forth relative to the frame 100 and be driven to reset under the action of the floor spring, so as to conduct a durability test on the floor spring.

[0032] The test door frame 200 has a driving component 230 located at the upper center. The swing device 300 includes a swing motor 310 and a swing rod 320 horizontally mounted at the output end of the swing motor 310 for swaying the driving component 230 back and forth. The rotation axis of the swing rod 320 is located directly in front of the rotating rod 220. In fact, as Figure 6 and Figure 7 As shown, the swing motor 310 drives the swing rod 320 to rotate clockwise. The swing rod 320 swings until it contacts the driving member 230, and drives the test door frame 200 to swing clockwise. As the test door frame 200 continues to swing, the distance between the driving member 230 and the conveying end of the swing motor 310 increases until the swing rod 320 separates from the driving member 230. Under the action of the floor spring, the test door frame 200 swings back counterclockwise to reset, thereby realizing the clockwise outward swing and counterclockwise reset of the test door frame 200. Similarly, when the swing motor 310 drives the swing rod 320 to rotate counterclockwise, it can also realize the counterclockwise outward swing and clockwise reset of the test door frame 200, preparing for the durability test of the bidirectional outward swing and reset of the floor spring.

[0033] The testing device includes a controller 410 mounted on a frame 100 and two first photoelectric switches 420 mounted on the frame 100 at left and right intervals for detecting the outside of the swing arm 320. The swing motor 310 and the first photoelectric switches 420 are both communicatively connected to the controller 410. In practice, the controller 410 can be a programmable controller 410 with an operation panel, capable of reading data from the first photoelectric switches 420 and controlling the swing motor 310 according to a set program to achieve the working control and counting functions of the floor spring durability test. The swing motor 310 drives the swing arm 320 to rotate clockwise until the first photoelectric switch 420 on the left detects the swing arm 320. The controller 410 then controls the swing motor 310 to rotate in the opposite direction according to the set program until the first photoelectric switch 420 on the right detects the swing arm 320. The controller 410 then controls the swing motor 310 to rotate in the opposite direction again according to the set program, thus automatically conducting the floor spring durability test. After the test is completed, the number of back-and-forth swings of the floor spring can be obtained by reading data from the controller 410.

[0034] The floor spring testing assembly of this utility model, through the cooperation of the frame 100, the test gate frame 200, the swing device 300 and the detection device, can drive the test gate frame 200 connected to the floor spring to swing back and forth in both directions and count, so as to realize the durability test of the floor spring by bidirectional swing and improve the reliability of the test.

[0035] Preferably, the distance between the rotating rod 220 and the driving member 230 is a, the distance between the rotating rod 220 and the rotation axis of the swing rod 320 is b, the distance between the rotating rod 220 and the outer side of the test door frame 200 is c, and the distance between the rotation axis of the swing rod 320 and the outer end of the swing rod 320 is d, then ba < d < ca. Figure 6 As shown, d > ba, ensuring that there is a part between the rotation axis of the swing rod 320 and the outer end of the swing rod 320 that can be released from the drive member 230 during the swinging process, so as to drive the test door frame 200 to swing back and forth; d < ca, then it can be ensured that the test door frame 200 has a suitable swing amplitude during the back and forth swinging process, ensuring that the floor spring swings back and forth at a suitable amplitude, and the outer end of the swing rod 320 does not extend beyond the outside of the test door frame 200.

[0036] Specifically, the driving component 230 is preferably a roller rotatably connected to the upper center of the test door frame 200. The rotation axis of the roller is perpendicular to the horizontal plane, and the outer diameter of the roller is larger than the thickness of the test door frame 200. In fact, when the swing arm 320 contacts the driving component 230 and drives the test door frame 200 to swing, the roller contacts the swing arm 320 and rolls relative to it during the swing, reducing the wear of the swing arm 320 and the driving component 230 and extending their service life. More specifically, the swing arm 320 is preferably a round rod with a hemispherical outer end. When the swing arm 320 and the driving component 230 are about to separate, the hemispherical surface replaces the flat surface to contact the roller, avoiding scratching the roller.

[0037] It should be noted that, as Figure 7 and Figure 8 As shown, the output end of the swing motor 310 preferably has a through hole 311 that is horizontally slidably connected to the swing rod 320. The output end of the swing motor 310 has a threaded through hole 312 that communicates with the through hole 311. The axis of the threaded through hole 312 is perpendicular to the axis of the through hole 311. The threaded through hole 312 is threadedly connected to a locking bolt 313 for abutting against the swing rod 320. Loosening the locking bolt 313 allows the swing rod 320 to slide back and forth relative to the through hole 311 until the swing rod 320 slides to the desired position. Tightening the locking bolt 313 locks the relative position of the swing rod 320 and the through hole 311. By cooperating with the swing rod 320, the through hole 311, and the locking bolt 313, the distance between the rotation axis of the swing rod 320 and the outer end of the swing rod 320 can be adjusted, and the position where the swing rod 320 is separated from the drive component 230 can be changed, thereby adjusting the swing amplitude and angle of the test door frame 200 and further improving the reliability of the floor spring durability test.

[0038] Specifically, the frame 100 preferably has two elongated through holes 120 extending forward and backward. Two first photoelectric switches 420 pass through each of the elongated through holes 120, and each first photoelectric switch 420 is threadedly connected to locking nuts 421 at the upper and lower ends of the frame 100 of the elongated through hole 120. In practice, when the forward and backward position of the first photoelectric switch 420 needs to be adjusted, the two locking nuts 421 are loosened, allowing the first photoelectric switch 420 to move forward and backward along the elongated through hole 120 as needed. Then, the two locking nuts 421 are tightened until they abut against the upper and lower ends of the frame 100 of the elongated through hole 120 to lock the forward and backward position of the first photoelectric switch 420. If the swing amplitude of the test door frame 200 decreases, the position of the first photoelectric switch 420 is adjusted forward accordingly, allowing the first photoelectric switch 420 to detect the swing arm 320 more quickly, shortening the waiting time for the swing arm 320 to swing back and contact the drive component 230, and improving the efficiency of the floor spring durability test.

[0039] Specifically, the detection device preferably includes a second photoelectric switch 430 mounted on the frame 100 and positioned directly in front of the pivot point of the swing arm 320's rotating rod 220, used to detect the upper exterior of the test door frame 200. The second photoelectric switch 430 is communicatively connected to the controller 410. In practice, when the swing arm 320 separates from the drive member 230, the test door frame 200 rebounds to its initial position under the action of the floor spring. After the second photoelectric switch 430 detects the upper exterior of the test door frame 200, the swing motor 310 of the controller 410 continues to operate, preventing the swing arm 320 from contacting the drive member 230 again before the test door frame 200 returns to its initial position, thus preventing interference with the floor spring's reset effect.

[0040] More specifically, the floor spring testing assembly of this utility model preferably includes a digital display 440 mounted on the frame 100 and connected to the controller 410. The digital display 440 can read and display the number of times the floor spring swings back and forth as obtained from the test in the controller 410, so that the operator can intuitively obtain the current test data of the floor spring test.

[0041] Specifically, the clamping mechanism 110 preferably includes two sets of positioning plates 111 spaced apart to the left and right, each positioning plate 111 being threadedly connected to a positioning bolt 112 for abutting against the left or right side of the floor spring. In practice, placing the floor spring between the two positioning plates 111 and then rotating the positioning bolt 112 to fix the position of the floor spring prevents it from shifting during the test; furthermore, it allows adjustment of the floor spring's position, ensuring the assembly connection accuracy between the floor spring's top axis and the test hole 210 of the test frame 200.

[0042] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
