[0001] The utility model relates to the technical field of door control accessories, in particular to a floor spring auxiliary inspection device. Background Art

[0002] A floor spring is a hydraulic door closer provided with a top shaft. The top shaft is a fitting for connecting a door frame and a door leaf at the upper part, and is composed of a bolt-adjustable plug-type shaft fixed on the door leaf and a shaft sleeve fixed on the door leaf.

[0003] Actually, the body of the floor spring is filled with oil, and the floor spring uses oil pressure to control the speed of the spring's resilience. At the same time, the floor spring is also provided with a speed regulating valve, which mainly controls the closing speed of the door by changing the flow rate of the oil in the body of the floor spring to ensure that the door can be closed smoothly and safely during the closing process.

[0004] After the floor spring is filled with oil, it is necessary to check its resilience performance. It is necessary to install the floor spring on the door leaf, and then open the door leaf to check the resilience performance of the floor spring by observation and measurement. However, due to the repeated lifting of the door leaf and the positioning of the floor spring during the installation and disassembly process of the floor spring and the door leaf, the labor intensity of manual installation and disassembly is relatively high, taking up more time and resulting in low inspection efficiency. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a floor spring auxiliary inspection device, which has lower labor intensity for installing and disassembling the floor spring, takes up less time, and improves inspection efficiency.

[0008] As an improvement of the above solution, the clamping mechanism includes a fixed plate fixed on the workbench, a movable plate arranged opposite to the fixed plate, and a clamping cylinder installed on the workbench for driving the movable plate to move towards the fixed plate.

[0009] As an improvement to the above-mentioned solution, the fixed plate is provided with a long through hole extending horizontally perpendicular to the moving direction of the movable plate, and the clamping cylinder also includes an adjusting bolt and an adjusting nut. A plurality of the adjusting bolts pass through the long through hole and are arranged at intervals, and each of the adjusting bolts is threadedly connected to two adjusting nuts for clamping the fixed plate.

[0010] As an improvement of the above solution, the jacking mechanism includes a jacking horizontal plate spanning above the fixed plate and the movable plate and a jacking cylinder for driving the jacking horizontal plate to move up and down.

[0011] As an improvement to the above solution, a guide groove is provided on the upper side of the lifting horizontal plate.

[0027] The following combines the attached drawings and specific embodiments to further describe the present invention, so as to more clearly understand the technical idea required to be protected by the present invention. Just for clarification, the upper, lower, left, right, front, back, inside, outside and other orientation terms that appear or will appear in the text of the present invention are only based on the attached drawings of the present invention, and they do not specifically limit the present invention.

[0028] As Figures 1 to 5 shown, a ground spring auxiliary inspection device in an embodiment of the present invention includes a workbench 100, a door frame 200, a clamping mechanism 300 installed on the workbench 100 for clamping the ground spring, and a lifting mechanism 400 for lifting the door frame 200. In fact, the clamping mechanism 300 can be a cylinder or a manual clamp in cooperation with components such as a positioning plate. After the ground spring is placed at the required position on the workbench 100, the clamping mechanism 300 acts to clamp the ground spring to fix the relative position between the ground spring and the workbench 100; the lifting mechanism 400 can be components such as a cylinder or a hydraulic cylinder that can lift the door frame 200.

[0029] The door frame 200 is provided with a rotating column 210. At the upper end of the rotating column 210, there is a connecting cylinder 211 that is slidably and rotatably connected to the workbench 100 in the up and down direction. The floor spring is provided with a ceiling shaft 500. At the lower end of the rotating column 210, there is a connecting groove 212 for the ceiling shaft 500 to extend into so that the door frame 200 rotates synchronously with the ceiling shaft 500. After installation, the door frame 200 can rotate around the axis of the rotating column 210; actually, the rotation axis line of the connecting cylinder 211 is the rotation axis line of the rotating column 210; the cross-sections of the ceiling shaft 500 and the connecting groove 212 can be polygons that match each other; when the door frame 200 moves downward, the ceiling shaft 500 can extend into the connecting groove 212. If the door frame 200 rotates, under the mutual cooperation of the connecting groove 212 and the ceiling shaft 500, the door frame 200 drives the ceiling shaft 500 to rotate relative to the floor spring; when the door frame 200 moves upward, the connecting groove 212 can separate from the ceiling shaft 500, which is convenient for the installation and disassembly of the floor spring.

[0030] The specific working principle of the floor spring auxiliary inspection device according to the embodiment of the present invention is as follows: Initially, the output end of the lifting mechanism 400 is in the upper position and lifts the door frame 200; the floor spring is placed at the corresponding position on the workbench 100 (the rotation axis line of the ceiling shaft 500 coincides with the rotation axis line of the connecting cylinder 211), and the clamping mechanism 300 acts to fix the position of the floor spring on the workbench 100, realizing the positioning of the floor spring; the output end of the lifting mechanism 400 moves downward and resets, and the door frame 200 moves downward, so that the ceiling shaft 500 extends into the connecting groove 212, and the output end of the lifting mechanism 400 leaves the door frame 200; at this time, the door frame 200 can be toggled to rotate, and under the action of the floor spring, the door frame 200 resets, which can assist the operator in observing and inspecting; after the inspection is completed, the output end of the lifting mechanism 400 is in the upper position and lifts the door frame 200, and the connecting groove 212 separates from the ceiling shaft 500 to separate the door frame 200 from the floor spring; the clamping mechanism 300 releases the clamping of the floor spring, and the floor spring is taken away.

[0031] The floor spring auxiliary inspection device according to the embodiment of the present invention can fix the relative position of the floor spring and the workbench 100 through the mutual cooperation of the workbench 100, the door frame 200, the clamping mechanism 300, the lifting mechanism 400, the rotating column 210, the connecting cylinder 211, the ceiling shaft 500 and the connecting groove 212. There is no need for manual repeated lifting of the door frame 200, the labor intensity of installing and disassembling the floor spring is lower, it takes less time, and the inspection efficiency is improved.

[0032] Specifically, the workbench 100 is preferably provided with support columns 110. A connecting plate 111 is provided at the upper end of the support columns 110. The connecting plate 111 is provided with a connecting round hole 112 that matches the connecting cylinder 211. The clamping mechanism 300 is arranged below the connecting round hole 112 so that after the floor spring is fixed on the workbench 100, the ceiling shaft 500 is located below the connecting cylinder 211. In fact, the connecting cylinder 211 is a long strip-shaped cylinder that matches the connecting round hole 112. Therefore, the connecting cylinder 211 can rotate and slide up and down relative to the connecting round hole 112, realizing the up-and-down sliding connection and rotational connection between the connecting cylinder 211 and the workbench 100.

[0033] Furthermore, the clamping mechanism 300 preferably includes a fixing plate 310 fixed on the workbench 100, a movable plate 320 arranged opposite to the fixing plate 310, and a clamping cylinder 330 installed on the workbench 100 for driving the movable plate 320 to move towards the fixing plate 310. When it is necessary to clamp the floor spring, place the floor spring on the workbench 100 between the fixing plate 310 and the movable plate 320, and make one side of the floor spring abut against the fixing plate 310 to realize the positioning of the floor spring. Then the clamping cylinder 330 acts to drive the movable plate 320 to move towards the fixing plate 310, clamping the floor spring from both sides of the floor spring to fix the floor spring on the workbench 100.

[0034] Even further, the fixing plate 310 is preferably provided with a long strip through hole 311 extending horizontally along a direction perpendicular to the moving direction of the movable plate 320. The clamping cylinder 330 further includes an adjusting bolt 340 and an adjusting nut 350. A plurality of the adjusting bolts 340 pass through the long strip through hole 311 and are arranged at intervals. Each of the adjusting bolts 340 is threadedly connected with two adjusting nuts 350 for clamping the fixing plate 310. In fact, Figure 5 the figure shows the case of three adjusting bolts 340, and the number of adjusting bolts 340 can be increased or decreased according to the situation in actual use. After the two adjusting nuts 350 on the adjusting bolt 340 clamp the fixing plate 310, the position of the adjusting bolt 340 is fixed. The ends of the plurality of adjusting bolts 340 can contact the floor spring on one side instead of the fixing plate 310, and can be applicable to floor springs with a curved surface on one side of the edge contour. In addition, by changing the relative position between the adjusting bolt 340 and the fixing plate 310, the position of the ceiling shaft 500 after the floor spring is clamped can also be adjusted, so as to be applicable to floor springs with different external dimensions within a certain range, expanding the applicable range of the floor spring auxiliary inspection device of the embodiment of the present invention.

[0035] Specifically, the lifting mechanism 400 preferably includes a lifting plate 410 spanning above the fixed plate 310 and the movable plate 320, and a lifting cylinder 420 for driving the lifting plate 410 to move up and down. The lifting cylinder 420 drives the lifting plate 410 to move up and down, thereby lifting or lowering the door frame 200.

[0036] Furthermore, the upper side of the lifting plate 410 is preferably provided with a guide groove 411. This guide groove 411 extends horizontally, perpendicular to the direction of movement of the movable plate 320, and has a cross-section that is an isosceles trapezoid with a larger upper base than the lower base. In practice, guided by the guide groove 411, the door frame 200 contacts the bottom of the guide groove 411, ensuring stability when the door frame 200 is lifted by the lifting plate 410. Furthermore, the guide groove 411 is preferably provided with a cushioning pad 412 to reduce rigid impact between the door frame 200 and the guide groove 411, thereby extending the service life of the door frame 200 and the lifting plate 410.

[0037] Furthermore, the workbench 100 is preferably provided with a circular plate 120 on the side of the lifting mechanism 400 facing away from the support column 110, and a universal ball 220 is provided on the underside of the door frame 200 for contacting the upper side of the circular plate 120. In practice, the contact between the universal ball 220 and the circular plate 120 provides an additional support point for the rotation of the door frame 200, thereby ensuring smoother rotation of the door frame 200 relative to the workbench 100.
