Description

Technical Field

[0001] This utility model relates to the field of rebound hammer technology, specifically to a rebound hammer for supervision purposes. Background Technology

[0002] The basic principle of a rebound hammer is to use a spring to drive a hammer. The hammer strikes a spring rod that is in perpendicular contact with the concrete surface with constant kinetic energy, causing local concrete deformation and absorbing some energy. The other part of the energy is converted into the rebound kinetic energy of the hammer. When all the rebound kinetic energy is converted into potential energy, the hammer rebounds to its maximum distance. The instrument displays the maximum rebound distance of the hammer as the rebound value (the ratio of the maximum rebound distance to the initial length of the spring).

[0003] Existing rebound hammers are prone to slipping from the hand and being damaged due to their smooth surface and large gripping parts. Therefore, a rebound hammer for supervision purposes is proposed.

[0004] A rebound hammer for construction supervision, disclosed in publication number CN217901454U, aims to solve the problem of improper operation by personnel during impact measurements. Its key technical features include: an instrument body with an impact rod slidably connected to its front end; a sleeve fitted onto the outer periphery of the instrument body; and the sleeve applying a force to the instrument body during its sliding stroke away from the impact rod, hindering its sliding towards the rod. This invention can prevent improper operation by personnel during impact measurements, thereby ensuring the accuracy of the rebound hammer data.

[0005] While the aforementioned patent can prevent improper operation by operators during impact measurement, thus ensuring the accuracy of the rebound hammer data, the device lacks a sealing structure in the detection probe section. The detection probe is the core of the rebound hammer, responsible for contacting the concrete surface and collecting rebound information. Therefore, it needs to be sealed to prevent external dust and moisture from entering the equipment and affecting its service life.

[0006] Therefore, it is necessary to invent a rebound hammer for supervision to solve the above problems. Utility Model Content

[0007] The technical problem to be solved by this utility model is as follows: to provide a supervision rebound hammer with high practicality, simple operation and simple structure, which solves the problem mentioned in the background art that the rebound hammer is easy to slip from the hand during use due to its smooth surface and large gripping part, causing damage to the rebound hammer.

[0008] The objective of this utility model can be achieved through the following technical solutions:

[0009] A rebound hammer for supervision includes a rebound hammer body, a probe connection port installed at the end of the rebound hammer body, a sealing mechanism installed inside the probe connection port, and a protective mechanism fixedly connected to the back of the rebound hammer body. The sealing mechanism includes an O-ring installed inside the probe connection port, and a support spring installed inside the O-ring. The protective mechanism includes an elastic rope fixedly connected to the back of the rebound hammer body, and an elastic wristband fixedly connected to one side of the elastic rope.

[0010] As a further embodiment of this utility model: a protective pad is fixedly connected to the surface of the rebounder body, and a cavity is opened inside the protective pad. A heating mechanism is fixedly connected inside the cavity, which helps to improve the user's comfort when working in winter.

[0011] As a further embodiment of this utility model: the heating mechanism includes a heating mesh fixedly connected inside the cavity, one side of the heating mesh is electrically connected to a storage battery via a power line, and the other side of the heating mesh is electrically connected to a temperature controller via a power line, so that the storage battery can provide continuous power.

[0012] As a further embodiment of this utility model: a PLC control box is fixedly connected to the surface of the protective pad, and a lighting lamp is installed on one side of the PLC control box to improve visibility during nighttime operations.

[0013] As a further embodiment of this utility model: both the battery and the temperature controller are mounted on the surface of the PLC control box, one side of the battery is electrically connected to one side of the lighting lamp via a power line, and the temperature controller facilitates the control of the heating grid temperature.

[0014] As a further embodiment of this utility model: a detection probe is slidably connected inside the probe connection port, and the detection probe is slidably connected to the inner wall of the O-ring seal. The O-ring seal facilitates the prevention of external dust and moisture from entering the equipment.

[0015] As a further embodiment of this utility model: a handle is fixedly connected to one edge of the surface of the rebound device body, and a number of anti-slip hemispheres are installed on the surface of the handle, which facilitates the gripping force of the hand.

[0016] The beneficial effects of this utility model are:

[0017] 1. By setting up a protective mechanism, when using the equipment, the main body of the rebounder is taken out of the box, and the elastic wristband at the end of the elastic rope on the back of the rebounder is put on the user's wrist. Then, the user holds the handle to operate, thus achieving the effect of protecting the main body of the rebounder. Compared with the traditional rebounder, which is inconvenient for users to handle and is easy to slip off the hand during use, shortening the service life of the rebounder.

[0018] 2. Due to the sealing mechanism, during use, especially in rainy or snowy weather, external moisture and dust can easily enter the equipment through the gaps between the detection probe and the probe connection port. Therefore, an O-ring is installed inside the probe connection port, and a support spring is also installed inside the O-ring. The support spring provides additional support force, allowing the O-ring to fit tightly against the detection probe surface, improving the sealing performance of the O-ring, and effectively preventing external dust and moisture from damaging the inside of the equipment.

Then, the user holds the handle 10 to perform the operation, thus achieving the effect of protecting the rebounder body 1. Compared with the traditional rebounder body 1, which is inconvenient for users to handle and is prone to slipping off the hand during use, shortening the service life of the rebounder body 1, the sealing mechanism 3 includes an O-ring 301 installed inside the probe connection port 2, and a support spring 302 is installed inside the O-ring 301. The protective mechanism 4 includes an elastic rope 401 fixedly connected to the back of the rebounder body 1, and an elastic wristband 402 fixedly connected to one side of the elastic rope 401.

[0027] like Figure 3 As shown, a protective pad 5 is fixedly connected to the surface of the rebounder body 1. A cavity is opened inside the protective pad 5. A heating mechanism 6 is fixedly connected inside the cavity. The heating mechanism 6 helps to improve the user's comfort when working in winter.

[0028] like Figure 3 As shown, the heating mechanism 6 includes a heating grid 601 fixedly connected inside the cavity.

[0033] The model of the rebound hammer body 1 is ZBL-S280; the above parameters and models can be selected according to the actual situation.

[0034] The working principle of this utility model is as follows: When using the equipment, take the rebounder body 1 out of the box, put the elastic wristband 402 at the end of the elastic rope 401 on the back of the rebounder body 1 on the user's wrist, and then hold the handle 10 to perform the operation.

[0035] When in use, especially in rainy or snowy weather, external moisture and dust can easily enter the device through the gap between the detection probe 9 and the probe connection port 2. Therefore, an O-ring 301 is installed inside the probe connection port 2, and a support spring 302 is also provided inside the O-ring 301. The support spring 302 can provide additional support force so that the O-ring 301 can fit tightly against the surface of the detection probe 9.
