Description

Technical Field

[0001] The utility model belongs to the field of test hammers, and in particular relates to a flat plate support anti-seismic force test hammer. Background Art

[0002] The plate bearing seismic force test hammer is a tool used to test the seismic performance of the plate bearing under earthquake or other vibration conditions. It generally consists of a weight (such as an iron block) and a handle. The use of the plate bearing seismic force test hammer is as follows: 1. Place the plate bearing on the test bench or on the ground to ensure that it is stable.

[0003] 2. Holding the handle, place the heavy part of the test hammer close to the flat support.

[0004] 3. Move the handle quickly so that the weight hits the flat plate support.

[0005] 4. Observe the seismic performance of the plate support, if there is any damage or displacement.

[0006] 5. Based on the test results, evaluate the seismic resistance of the plate bearing and make necessary improvements or adjustments. The plate bearing seismic force test hammer is a simple and practical tool that can evaluate the seismic performance of the plate bearing by simulating earthquake conditions to ensure its safety and reliability in actual use.

[0007] However, the length of the test hammer is fixed, which is not suitable for testing different supports. The hammer head of the test hammer is hard and is easy to damage the support during the test. Therefore, it needs to be improved. Summary of the invention

[0008] The utility model aims to provide a flat support anti-seismic force testing hammer, which solves the problems of the existing testing hammer having a fixed length and the support being easily damaged during testing.

[0009] In order to achieve the above-mentioned purpose, the utility model provides a flat plate support seismic force testing hammer, including a hammer handle and a hammer head. The outer side of the hammer handle is fixedly connected with an anti-slip sleeve, the right end of the hammer handle is rotatably connected with a rotating disk, the middle part of the right end of the hammer handle is connected with a screw rod through a bearing, the screw rod is fixedly connected to the rotating disk, and protective mechanisms are arranged at both ends of the hammer head.

[0010] The principle of the utility model is that when in use, the support is fixed on the ground, and the operator uses a test hammer cabinet to hammer the support. The outer side of the hammer head is wrapped with a rubber sleeve, which prevents the hammer head from damaging the support. The rubber sleeve is fixed by a fixing block, and the tension spring pulls the fixing ring toward the hammer head through tension. The sliding rod slides into the hammer head to fix the fixing block, thereby avoiding the problem that the hammer head easily damages the support. A rotating disk is provided at the right end of the test hammer, which drives the screw to rotate, and the screw controls the movement of the extension rod. The extension rod controls the length of the test hammer, thereby avoiding the length of the test hammer being fixed and testing with different supports is not used.

[0011] The beneficial effect of the utility model is that a rotating disk is arranged at the right end of the test hammer, the rotating disk drives the screw to rotate, the screw controls the movement of the extension rod, and the extension rod controls the length of the test hammer, thereby avoiding the need to fix the length of the test hammer and not using tests with different supports.

[0012] A rubber sleeve is wrapped around the outside of the hammer head to prevent the hammer head from damaging the support. The rubber sleeve is fixed by a fixing block. The tension spring pulls the fixing ring toward the hammer head through tension. The sliding rod slides into the hammer head to fix the fixing block, thereby avoiding the problem that the hammer head easily damages the support.

[0013] Furthermore, the protection mechanism includes a rubber sleeve, a fixing block, a slide rod, a fixing ring, and a tension spring. The outer side of the hammer head contacts the rubber sleeve, the end of the rubber sleeve close to the extension rod is fixedly connected to the fixing block, the outer side of the slide rod is fixedly connected to the fixing ring, and the outer side of the slide rod is provided with a tension spring. The protection mechanism is provided to prevent the hammer head from damaging the support.

[0014] Furthermore, the outer side of the screw rod is connected with an extension rod through a thread, and the left end of the extension rod is fixedly connected with a hammer head. Through the setting of the extension rod, the extension rod controls the length of the test hammer.

[0015] Further, the number of the rubber sleeves is two, and the two rubber sleeves are symmetrically distributed on the hammer head. Through the arrangement of the rubber sleeves, the rubber sleeves wrap the hammer head.

[0016] Furthermore, the number of the slide bars is multiple, and the multiple slide bars are symmetrically distributed on the hammer head. Through the setting of the slide bars, the slide bars limit the fixed block.

[0017] Furthermore, a slide bar is slidably connected inside the fixing block, and the slide bar is slidably connected to the hammer head. Through the setting of the fixing block, the fixing block fixes the rubber sleeve.

[0018] Furthermore, one end of the tension spring is fixedly connected to the fixing block, and the other end of the tension spring is fixedly connected to a fixing ring. Through the setting of the fixing ring, the fixing ring controls the position of the slide bar. BRIEF DESCRIPTION OF THE DRAWINGS
