Description
A portable rebar detector Technical Field
[0001] This application relates to the field of building inspection technology, and in particular to a portable rebar detector. Background Technology
[0002] In today's construction industry, rebar detectors have become an indispensable tool for building quality inspection. They can quickly and accurately measure the position and spacing of rebars, providing important data for assessing the stability and safety of building structures.
[0003] Existing rebar detectors consist of a main unit, a probe, and a connecting cable; as a key component for data transmission, the reliability and ease of use of the connecting cable are crucial for improving the overall performance of the equipment.
[0004] In traditional rebar detectors, the connecting wires often become tangled during storage. This not only affects the cleanliness of the equipment but may also damage the lifespan of the connecting wires and even affect the ease of use in the future. Therefore, a rebar detector that reduces the tangling of the connecting wires is needed. Summary of the Invention
[0005] To reduce the likelihood of the connecting wires becoming tangled during storage, this application provides a portable rebar detector.
[0006] The portable rebar detector provided in this application adopts the following technical solution:
[0007] A portable rebar detector includes a main unit, a probe, and a connecting wire. One end of the connecting wire is connected to the main unit, and the other end of the connecting wire is detachably connected to the probe. A winding column is provided on the outer wall of the main unit, and the connecting wire is wound around the outer wall of the winding column. A positioning element is installed on the winding column, which is used to connect the end of the connecting wire away from the main unit to the winding column.
[0008] By adopting the above technical solution, when it is necessary to store the rebar detector, the connecting wire can be separated from the probe first, and then the connecting wire can be neatly wound around the winding column on the outer wall of the main unit. Finally, the end of the connecting wire is firmly fixed to the winding column using positioning components, thereby effectively preventing the connecting wire from becoming loose or unraveling on its own, ensuring that the connecting wire is neatly arranged, reducing tangling and knotting, and improving the cleanliness of the equipment and the convenience of future use.
[0009] Optionally, the positioning element is configured as an elastic tube, the sidewall of which is connected to the sidewall of the winding column; the inner diameter of the elastic tube is adapted to the outer diameter of the connecting line, and the elastic tube has a clearance opening for the connecting line to be inserted.
[0010] By adopting the above technical solution, the end of the connecting wire can be smoothly inserted into the interior of the elastic tube through the clearance opening on the elastic tube. Due to the elasticity of the elastic tube itself, the clearance opening can be easily opened during the insertion process, thus facilitating the entry and fixation of the connecting wire end into the elastic tube.
[0011] This design not only simplifies the operation process, but also effectively avoids the problem of loose and tangled ends of the connecting wires when not in use, improving the overall neatness and portability of the device.
[0012] Optionally, one end of the winding column is provided with a rotating shaft, the extension direction of the rotating shaft is perpendicular to the extension direction of the winding column, the main unit is provided with an extension part, the rotating shaft is rotatably connected to the extension part, and the main unit is provided with a fixing component for fixing the winding column to the main unit.
[0013] By adopting the above technical solution, the rotating shaft allows the winding column to rotate relative to the main unit. During use, the rotating shaft can be adjusted to be perpendicular to the side wall of the main unit, facilitating smooth winding of the connecting wire onto the winding column by the operator. After winding is complete, the winding column can be further rotated so that the direction of the rotating shaft is parallel to the side wall of the main unit. This reduces the space occupied by the entire device and prevents the exposed rotating shaft from being damaged by accidental impacts, thus improving the portability and durability of the equipment.
[0014] Optionally, the fixing component includes a rubber layer that wraps around the outer peripheral wall of the rotating shaft.
[0015] By adopting the above technical solution, the rubber layer wrapped around the outer peripheral wall of the rotating shaft can effectively increase the friction between the rotating shaft and the extension, thereby preventing the winding column from rotating freely when not subjected to external force and ensuring the stability of the winding state of the connecting wire.
[0016] Optionally, the fixing component includes a gear and a pull rod. A toothed groove is provided on one side of the extension, and a pull groove communicating with the toothed groove is provided at one end of the rotating shaft. The pull rod is movably installed in the pull groove and exposed to the outside. A guide block is provided on the outer wall of the pull rod, and a guide groove is provided on the inner wall of the pull groove for the guide block to slide. The gear is installed on the pull rod and is used to engage with the toothed groove.
[0017] By adopting the above technical solution, the cooperation between the gear and the pull rod enables the fixing and unlocking of the winding column. Specifically, when the pull rod is pulled, the guide block slides in the guide groove, causing the gear to disengage from the tooth groove, thereby releasing the restriction on the winding column and allowing the winding column to rotate freely to complete the winding or unwinding of the connecting wire.
[0018] Optionally, a first spring is provided on the pull rod and the inner wall of the groove, and the elastic force of the first spring is used to drive the gear to be inserted into the groove under normal conditions.
[0019] By adopting the above technical solution, the first spring can stably insert the gear into the tooth groove under normal conditions, thereby fixing the winding column to the main unit and preventing the winding column from rotating unexpectedly when not in operation.
[0020] Optionally, the host is equipped with a positioning block, the probe is provided with a dovetail block, and the positioning block has a dovetail groove for the dovetail block to be inserted.
[0021] By adopting the above technical solution, the cooperation between the dovetail block and the dovetail groove can realize the connection between the probe and the host, thereby avoiding probe loss and facilitating quick installation and removal of the probe.
[0022] Optionally, the inner wall of the dovetail groove is provided with a first fixing groove, and a fixing rod is movably installed in the first fixing groove; one end of the fixing rod is provided with a hemispherical head, and the dovetail block is provided with a second fixing groove for the hemispherical head to be inserted; a second spring is provided between the fixing rod and the first fixing groove, and the elastic force of the second spring is used to drive the hemispherical head to be inserted into the second fixing groove in the normal state.
[0023] By adopting the above technical solution, a first fixing groove is opened on the inner wall of the dovetail groove, and a fixing rod is movably installed there. One end of the fixing rod is provided with a hemispherical head that cooperates with the second fixing groove on the dovetail block. The elastic force of the second spring allows the hemispherical head to be inserted into the second fixing groove under normal conditions. This structural design not only enables rapid positioning and stable connection between the probe and the main unit, but also effectively avoids the probe from becoming loose or falling off during use.
[0024] Meanwhile, when disassembly is required, simply pulling the probe will allow the hemispherical head to overcome the elastic force of the second spring and retract into the first fixing groove, making the operation simple and reliable.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. When it is necessary to store the rebar detector, the connecting wire can be separated from the probe first, and then the connecting wire can be wound neatly around the winding column on the outer wall of the main unit; finally, the end of the connecting wire can be firmly fixed to the winding column using the positioning piece, thereby effectively preventing the connecting wire from loosening or unfolding on its own, ensuring that the connecting wire is neatly arranged, reducing the occurrence of tangling and knotting, improving the cleanliness of the equipment and the convenience of the next use;
[0027] 2. By rotating the winding column, the rotating shaft can be adjusted to be perpendicular to the side wall of the main unit during use, making it easy for the operator to smoothly wind the connecting wire onto the winding column. After winding, the winding column can be further rotated so that the direction of the rotating shaft is parallel to the side wall of the main unit. This reduces the space occupied by the entire device and avoids damage caused by accidental collisions due to the exposed rotating shaft, thus improving the portability and durability of the equipment.

[0035] The present application will be further described in detail below with reference to Figures 1-6.
[0036] Example 1:
[0037] This application discloses a portable rebar detector.
[0038] Referring to Figure 1, a portable rebar detector includes a main unit 1, a probe 2, and a connecting cable 3. One end of the connecting cable 3 is connected to the upper surface of the main unit 1, and the other end of the connecting cable 3 is detachably connected to the probe 2. A winding post 4 is provided on the outer wall of the main unit 1, and the connecting cable 3 can be wound around the outer wall of the winding post 4. In addition, a positioning element 5 is installed on the winding post 4, which is used to connect the end of the connecting cable 3 away from the main unit 1 to the winding post 4, thereby preventing the connecting cable 3 from becoming loose.
[0039] The winding column 4 is made of plastic tube and its surface is polished to reduce friction. One end of the winding column 4 is provided with a rotating shaft 41, and the extension direction of the rotating shaft 41 is perpendicular to the extension direction of the winding column 4. An extension 11 is provided on one side of the main unit 1, and the two ends of the rotating shaft 41 are rotatably connected to the extension 11. The main unit 1 is provided with a fixing component 6 for fixing the winding column 4 to the main unit 1.
[0040] Referring to Figure 2, in this embodiment, the fixing component 6 includes a rubber layer 61, which wraps around the outer peripheral wall of the rotating shaft 41. The cooperation between the rotating shaft 41 and the extension 11 allows the winding column 4 to rotate flexibly, making it convenient for the user to adjust the winding angle as needed. The addition of the rubber layer 61 increases the friction between the rotating shaft 41 and the extension 11, preventing the winding column 4 from rotating arbitrarily when not in operation.
[0041] The positioning component 5 is set as an elastic tube, and the side wall of the elastic tube is attached to the winding column 4 with glue. The inner diameter of the elastic tube is the same as the outer diameter of the connecting wire 3, and the elastic tube has a relief opening 51 for the connecting wire 3 to be inserted. The width of the relief opening 51 is smaller than the diameter of the connecting wire 3. The elasticity of the elastic tube itself can facilitate the insertion of the connecting wire 3 into the relief opening 51, and the width of the relief opening 51 can reduce the possibility of the connecting wire 3 coming off.
[0042] The implementation principle of Embodiment 1 of this application is as follows:
[0043] When storing the rebar detector, the connecting wire 3 can be separated from the probe 2 first; then the winding column 4 can be rotated to facilitate the operator to smoothly wind the connecting wire 3 onto the winding column 4; after winding, the end of the connecting wire 3 is firmly fixed to the winding column 4 using an elastic tube, thereby effectively preventing the connecting wire 3 from loosening or unfolding on its own; ensuring that the connecting wire 3 is neatly arranged, reducing the occurrence of tangling and knotting, improving the cleanliness of the equipment and the convenience of the next use.
[0044] Finally, rotate the winding column 4 so that the direction of the rotating shaft 41 is parallel to the side wall of the main unit 1. This reduces the space occupied by the entire device and prevents the rotating shaft 41 from being exposed and damaged by accidental collisions, thus improving the portability and durability of the device.
[0045] Example 2:
[0046] This application discloses a portable rebar detector.
[0047] Referring to Figures 3 and 4, the difference between Embodiment 2 and Embodiment 1 of this application is that: the fixing component 6 includes a gear 63 and a pull rod 62, a toothed groove 12 is provided on one side of the extension 11, a groove 42 communicating with the toothed groove 12 is provided at one end of the rotating shaft 41, the pull rod 62 is slidably installed in the groove 42, and one end of the pull rod 62 passes through the toothed groove 12 and is exposed to the outside; a guide block 64 is integrally formed on the outer wall of the pull rod 62, and a guide groove 43 is provided on the inner wall of the groove 42 for the guide block 64 to slide. The cooperation between the guide block 64 and the guide groove 43 can prevent the pull rod 62 and the gear 63 from rotating freely.
[0048] The gear 63 has a mounting hole, which is fitted onto the outer wall of the pull rod 62. The inner diameter of the mounting hole is fixed to the outer wall of the pull rod 62. The gear 63 is used to engage with the tooth groove 12. When the pull rod 62 is pulled, the guide block 64 slides in the guide groove 43, causing the gear 63 to disengage from the tooth groove 12, thereby releasing the restriction on the winding column 4 and allowing the winding column 4 to rotate freely to complete the winding or unwinding of the connecting line 3.
[0049] In this embodiment, a first spring 65 is provided between the pull rod 62 and the inner wall of the groove 42. The elastic force of the first spring 65 is used to drive the gear 63 to be inserted into the tooth groove 12 under normal conditions, so as to prevent the winding column 4 from rotating unexpectedly when not in operation.
[0050] Example 3:
[0051] This application discloses a portable rebar detector.
[0052] Referring to Figure 5, the difference between Embodiment 3 and Embodiment 1 is that: a positioning block 13 is provided on one side of the host 1, and the positioning block 13 has a dovetail groove 14; a dovetail block 21 is provided on one side of the probe 2, and the dovetail block 21 is used to insert and cooperate with the dovetail groove 14 so as to connect the host 1 and the probe 2.
[0053] Referring to Figure 6, a first fixing groove 15 is provided on the inner wall of the dovetail groove 14, and a fixing rod 16 is movably installed in the first fixing groove 15; a hemispherical head 17 is integrally formed on the side of the fixing rod 16 away from the first fixing groove 15, and a second fixing groove 22 is provided on the dovetail block 21 for the hemispherical head 17 to be inserted into; and a second spring 18 is provided between the fixing rod 16 and the first fixing groove 15, and the elastic force of the second spring 18 is used to drive the hemispherical head 17 to be inserted into the second fixing groove 22 in the normal state.
[0054] The implementation principle of Embodiment 3 of this application is as follows:
[0055] A first fixing groove 15 is formed on the inner wall of the dovetail groove 14, and a fixing rod 16 is movably installed thereon. One end of the fixing rod 16 is provided with a hemispherical head 17, which cooperates with the second fixing groove 22 on the dovetail block 21. The elastic force of the second spring 18 is used to make the hemispherical head 17 inserted into the second fixing groove 22 in the normal state. This structural design not only enables the probe 2 to be quickly positioned and stably connected to the host 1, but also effectively avoids the probe 2 from becoming loose or falling off during use.
[0056] Meanwhile, when disassembly is required, simply pull the probe 2 to allow the hemispherical head 17 to overcome the elastic force of the second spring 18 and retract into the first fixing groove 15, making the operation simple and reliable.
[0057] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
