Description

Technical Field

[0001] This utility model relates to the field of construction equipment for building materials, and in particular to a switch protection structure for a rebar bending machine. Background Technology

[0002] Currently, steel bar bending machines are often used when processing steel bars on construction sites. The principle is that a horizontal working disc rotates on a vertical axis, and the steel bar is placed in a predetermined position on the working disc. The support pin is fixed on the machine tool, and the center pin and bending pin are mounted on the working disc. When the disc rotates, the steel bar can be bent.

[0003] Rebar bending machines typically use foot switches to control their operation. For ease of operation, they are designed to be portable, with operators often placing the foot switch near their bodies for convenient foot operation. However, because the foot switch is exposed, if materials such as rebar on the workbench fall and touch it during processing, or if an operator accidentally steps on the switch, it can trigger the rebar bending machine to move, posing a significant safety hazard to unprepared operators. Furthermore, the dust and sand present at construction sites can accumulate over time, potentially causing these particles to penetrate the switch, affecting contact conductivity, shortening its lifespan, or even causing it to malfunction.

[0004] Some related technologies also offer solutions, such as installing a cover on the foot switch. The cover can shield the foot switch and prevent accidental activation of the foot switch in the event of an accident where objects such as steel bars fall from above it.

[0005] There are still some shortcomings in the above-mentioned technologies. For example, operators may accidentally step on or touch the foot switch because they cannot see the situation inside the enclosure. Operators may also subconsciously or inadvertently step on the foot switch because they keep their feet on it for a long time. Utility Model Content

[0006] The purpose of this utility model is to provide a switch protection structure for a rebar bending machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a switch protection structure for a rebar bending machine, comprising a base plate, a foot switch disposed on the base plate, and a protective cover disposed on the base plate. The protective cover covers the periphery of the foot switch and has an opening on one side of the protective cover to accommodate a foot extending into the protective cover. A first limiting block is provided on the side of the base plate near the tip of the foot switch, and the first limiting block is rotatably connected to the protective cover. A support portion is provided on the side of the base plate near the foot switch, which allows a foot to be placed on it, and the side of the support portion can limit the side of the foot.

[0008] By adopting the above technical solution, the protective cover is configured with an opening for accommodating a foot, and the side of the protective cover away from the opening is rotatably connected to a first limiting block on the base plate. This ensures that the foot can only be inserted into the protective cover from one side opening to operate the foot switch. The support allows operators to rest their feet briefly on the support when operating the equipment for extended periods but with infrequent operation. When not operating the equipment, the feet can be placed on the support, and the foot switch can be operated only when needed. This effectively reduces operator fatigue and prevents accidents caused by operators unconsciously or unintentionally stepping on the foot switch while keeping their feet on it for extended periods. The side of the support also limits the movement of the foot, preventing accidental stepping. Furthermore, installing the foot switch inside the protective cover prevents materials such as steel bars on the workbench from falling and touching the foot switch, thus improving equipment safety.

[0009] Preferably, at least two foot switches are provided, and the support portion is provided between adjacent foot switches.

[0010] By adopting the above technical solution, adjacent foot switches are separated, enabling operators to quickly find the correct foot position when they need to step on the foot switch, improving production efficiency and preventing misoperation. It can also effectively prevent workers from accidentally stepping on or touching the foot switch because they cannot see the situation inside the enclosure.

[0011] Preferably, the top surface of the support is provided with an inclined surface, which is inclined downward in a direction away from the protective cover.

[0012] By adopting the above technical solution, the top surface of the support is set to slope downwards in the direction away from the protective cover, which is convenient for the operator's feet to place. The slope of the slope is adapted to the angle between the operator's heel and the ground or base plate when the heel touches the ground, so as to make the staff more comfortable when resting and relaxing.

[0013] Preferably, the top surface of the protective cover is inclined.

[0014] By adopting the above technical solution, the inclined top surface of the protective cover will cause materials such as steel bars to roll down the slope to the ground when they fall from the workbench, preventing the materials from rolling to the other side and hitting the operators.

[0015] Preferably, a buffer reset component is provided between the protective cover and the limiting block, and a buffer space is reserved between the bottom side of the protective cover and the top surface of the base plate. When the protective cover is compressed, the protective cover can rotate to buffer and release the force.

[0016] By adopting the above technical solution, when objects such as steel bars fall onto the protective cover, the protective cover presses down and causes the upper abutment part of the buffer reset component to contract. The buffer reset component can generate a certain degree of flexible deformation to provide a buffering effect. The protective cover continues to press down until the bottom surface contacts the base plate, and the subsequent impact force is borne by the protective cover and the base plate.

[0017] Preferably, the protective cover is rotatably connected to both sides of the first limiting block via a connector. The protective cover is symmetrically provided with two second limiting blocks located above the position of the connector. The buffer reset member is sleeved on the outer surface of the connector. The buffer reset member has an upper abutment portion that contacts the bottom surface of the second limiting block and a lower abutment portion that contacts the outer surface of the base plate.

[0018] By adopting the above technical solution, the upper abutment part of the buffer reset component provides support for the protective cover, thereby preventing the protective cover from falling down and reducing the limiting space. At the same time, after objects such as steel bars roll down the slope of the protective cover to the ground, the buffer reset component rebounds, and the upper and lower abutment parts work together to drive the protective cover back to its correct position. Meanwhile, the setting of the abutment part of the buffer reset component separates the inner facade of the protective cover from the outer facade of the base plate into a limiting space of a suitable size, which makes it convenient for the operator to put their feet into the protective cover to operate the foot switch. After a heavy object falls, it can also drive the protective cover to quickly and automatically return to its correct position without the need for manual operation, effectively improving work efficiency.

[0019] Preferably, the protective cover is rotatably connected to the top surface of the side with the movable opening of the protective cover via a rotating component.

[0020] By adopting the above technical solution, when the foot switch is in use, the protective cover is flipped back and placed on the top surface of the protective cover, which does not affect the operator's ability to insert their foot into the receiving cavity to operate the foot switch. When the foot switch is not in use, the protective cover is flipped forward and placed in front of the movable opening on one side of the protective cover, which can effectively prevent dust and sand from entering the switch, improve the service life of the foot switch and prevent the foot switch from malfunctioning.

[0021] Preferably, the base plate is provided with a buffer plate extending outward from the toe of the foot, and the buffer plate is in the shape of an inverted U, with one side fixedly connected to the base plate and the other side located on the top surface of the protective cover.

[0022] By adopting the above technical solution, the buffer plate is placed on top of the protective cover. When materials such as steel bars fall from the workbench, they will first come into contact with the buffer plate, and then the impact force will be dispersed by the buffer plate before falling onto the protective cover. This avoids the protective cover directly colliding with the materials, effectively improving the service life of the protective device. It can also further improve the safety of the equipment when facing some relatively heavy materials falling.

[0023] Preferably, the buffer plate is made of an elastic material.

[0024] By adopting the above technical solution, the buffer plate made of elastic material can play a good buffering role. When materials such as steel bars fall from the workbench, the impact force will be dispersed by the flexible deformation generated by the buffer plate.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The protective cover is designed with an opening for accommodating a foot, and the side of the cover away from the opening is rotatably connected to a first limiting block on the base plate. This ensures that the foot can only be inserted into the cover from one side to operate the foot switch. The support separates the two foot switches, effectively preventing workers from accidentally stepping on or activating the foot switches because they cannot see inside the cover. Furthermore, installing the foot switches inside the protective cover effectively prevents materials such as steel bars on the workbench from falling and activating the foot switches, thus improving equipment safety.

[0027] 2. Setting the height of the support to be higher than the height of the foot switch on the base plate allows operators to rest their feet on the support briefly during breaks in operating the equipment for extended periods but with infrequent operation. When not operating the equipment, the feet can be placed on the support, and the foot switch can be pressed only when operation is required. This reduces operator fatigue and effectively prevents accidents caused by operators unconsciously or unintentionally stepping on the foot switch while keeping their feet on it for extended periods.

[0028] 3. An elastic buffer plate is extended from the base plate and positioned above the protective cover. When materials such as steel bars fall from the workbench, they will first come into contact with the buffer plate. The impact force is then dispersed by the flexible deformation of the buffer plate before falling onto the protective cover. Unlike the hard-on-hard contact between the protective cover and the materials, the elastic buffer plate can play a good cushioning role, effectively extending the service life of the protective device. It can also further improve the safety of the equipment when facing the fall of some heavy materials. Attached Figure Description

Detailed Implementation

[0038] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0039] like Figure 1 As shown, in some related technologies, a protective cover 3 is used to protect the foot switch 2. The cover can shield the foot switch 2. In the event of an accident, if objects such as steel bars fall from above the foot switch 2, the protective cover 3 can block the falling objects to prevent accidental activation of the foot switch 2. The protective cover 3 consists of a baffle at the top and multiple side plates below the baffle to provide support. The foot switch 2 is placed in the space enclosed by the baffle and the side plates. One of the side plates has a slot as the inlet for the foot switch.

[0040] Please see Figures 2-3 This application discloses a switch protection structure for a rebar bending machine, including a base plate 1, a foot switch 2 disposed on the base plate 1, and a protective cover 3 disposed on the base plate 1. The protective cover 3 covers the periphery of the foot switch 2, and has an opening 31 on one side of the protective cover 3 to accommodate a foot extending into the protective cover 3. The base plate 1 has a first limiting block 11 on the side near the tip of the foot switch 2, and the first limiting block 11 is rotatably connected to the protective cover 3. The base plate 1 has a support portion 12 on the side near the foot switch 2, which allows a foot to be placed on it, and the side of the support portion 12 can limit the side of the foot.

[0041] Example 1

[0042] Please see Figure 2 and Figure 3 The protective cover 3 is configured with a movable opening 31 for accommodating a foot to enter the protective cover 3. The side of the protective cover 3 away from the movable opening 31 is rotatably connected to the first limiting block 11 on the base plate 1, so that the foot can only be inserted into the protective cover 3 through one side opening to operate the foot switch 2. The support part 12 is provided so that the operator can place their feet on the support part 12 for a short rest and relaxation when the operator needs to operate the equipment for a long time but not frequently, and can place their feet on the support part 12 when not operating the equipment. The foot switch 2 is pressed only when foot work is required, which effectively reduces operator fatigue and prevents accidents caused by operators unconsciously or unintentionally stepping on the foot switch 2 while keeping their feet on it for a long time. At the same time, the side of the support part 12 can limit the side of the foot to prevent the operator from accidentally stepping on the foot switch 2. In addition, the foot switch 2 is installed inside the protective cover 3 to prevent materials such as steel bars on the workbench from falling and touching the foot switch 2, thus improving the safety of the equipment.

[0043] Please see Figure 2 and Figure 7 In this embodiment, at least two foot switches 2 are provided, and the support part 12 is placed between adjacent foot switches 2. This can separate adjacent foot switches 2, so that when the operator needs to step on the foot switch 2, he / she can quickly find the correct stepping position, improve production efficiency, prevent misoperation, and also effectively avoid the operator from accidentally stepping on or touching the foot switch 2 because he / she cannot see the situation inside the cover.

[0044] Please see Figure 2 and Figure 7 In this embodiment, the top surface of the support 12 is provided with an inclined surface 121. The inclined surface 121 is inclined downward in the direction away from the protective cover 3. Setting the top surface of the support 12 to be inclined downward in the direction away from the protective cover 3 makes it easier for the operator's feet to be placed. The slope of the inclined surface 121 is adapted to the angle between the operator's heel and the ground or the base plate 1 when the heel touches the ground, so as to make it more comfortable for the staff to rest and relax.

[0045] Please see Figure 2 and Figure 3 In this embodiment, the top surface of the protective cover 3 is inclined. The inclined top surface of the protective cover 3 causes materials such as steel bars to roll down the slope to the ground when they fall from the workbench, preventing the materials from rolling to the other side and hitting the operator.

[0046] Please see Figure 2 , Figure 7 and Figure 8In this embodiment, a buffer reset member 4 is provided between the protective cover 3 and the first limiting block 11. A buffer space is reserved between the bottom side of the protective cover 3 and the top surface of the base plate 1. When the protective cover 3 is pressed, the protective cover 3 can rotate to buffer and release the force. When objects such as steel bars fall on the protective cover 3, the protective cover 3 presses down and causes the upper abutment part 41 of the buffer reset member 4 to contract. The buffer reset member 4 can produce a certain degree of flexible deformation to provide a buffering effect. The protective cover 3 continues to press down until the bottom surface contacts the base plate 1. The subsequent impact force is borne by the protective cover 3 and the base plate 1.

[0047] Please see Figure 2 , Figure 6 and Figure 7 In this embodiment, the protective cover 3 is rotatably connected to both sides of the first limiting block 11 via the connector 5. The protective cover 3 is symmetrically provided with two second limiting blocks 32 located above the connector 5. A buffer reset member 4 is sleeved on the outer surface of the connector 5. The buffer reset member 4 has an upper abutment portion 41 that contacts the bottom surface of the second limiting block 32 and a lower abutment portion 42 that contacts the outer surface of the base plate 1. The upper abutment portion 41 of the buffer reset member 4 provides support for the protective cover 3, thereby preventing the protective cover 3 from falling down and reducing the limiting space. Simultaneously, it prevents objects such as reinforcing bars from falling down. After the protective cover 3 rolls down the slope to the ground, the buffer reset component 4 rebounds, and the upper abutment part 41 and the lower abutment part 42 work together to drive the protective cover 3 back to its original position. At the same time, the setting of the abutment part of the buffer reset component 4 separates the inner surface of the protective cover 3 and the outer surface of the base plate 1 into a suitable limiting space, which makes it easy for the operator to put his foot into the protective cover 3 to operate the foot switch 2. After a heavy object falls, it can also drive the protective cover 3 to quickly and automatically return to its original position without the need for manual operation of the protective cover 3 to return to its original position, which effectively improves work efficiency. The buffer reset component 4 is set as a torsion spring.

[0048] The implementation principle of Embodiment 1 is as follows: The protective cover 3 is configured with an opening 31 for accommodating a foot to enter the protective cover 3, and the side of the protective cover 3 away from the opening 31 is rotatably connected to the first limiting block 11 on the base plate 1, so that the foot can only be inserted into the protective cover 3 from one side opening to operate the foot switch 2. The support part 12 allows the operator to place their feet on the support part 12 for a short rest and relaxation when the operator needs to operate the equipment for a long time but not frequently. When not operating the equipment, the foot can be placed on the support part 12. The foot switch 2 is pressed on the support 12 only when the foot is needed for operation, which effectively relieves operator fatigue and can also prevent accidents caused by the operator subconsciously or unintentionally stepping on the foot switch due to prolonged foot placement. At the same time, the side of the support 12 can limit the side of the foot to prevent the operator from accidentally stepping on the foot switch 2. In addition, the foot switch 2 is installed inside the protective cover 3 to prevent materials such as steel bars on the workbench from falling and touching the foot switch 2, thus improving the safety of the equipment.

[0049] Example 2

[0050] Please see Figure 4 The difference between this embodiment and the first embodiment is that the protective cover 7 is rotatably connected to the top surface of the protective cover 3 on one side with the movable opening 31 via the rotating member 6.

[0051] Please see Figure 4 In this embodiment, when the foot switch is in use, the protective cover is flipped back and placed on the top surface of the protective cover, which does not affect the operator's foot from reaching into the receiving cavity to operate the foot switch. When the foot switch is not in use, the protective cover is flipped forward and placed on the front of the movable opening of the protective cover, which can effectively prevent dust and sand from entering the switch, improve the service life of the foot switch and prevent the foot switch from malfunctioning. The rotating part 6 is set as a connecting rod.

[0052] The implementation principle of Embodiment 2 is as follows: When the foot switch 2 is in use, the protective cover 7 is flipped backward and placed on the top surface of the protective cover 3, which does not affect the operator's foot from being inserted into the receiving cavity to operate the foot switch 2. When the foot switch 2 is not in use, the protective cover 7 is flipped forward and placed in front of the movable opening 31 on one side of the protective cover 3, which can effectively prevent dust and sand from entering the inside of the switch, improve the service life of the foot switch 2 and prevent the foot switch 2 from malfunctioning.

[0053] Example 3

[0054] Please see Figure 5 and Figure 6 The difference between this embodiment and the first embodiment is that a buffer plate 8 is provided on the base plate 1 extending outward from the toe of the foot.

[0055] Please see Figure 5 and Figure 6 In this embodiment, a buffer plate 8 is provided on the base plate 1 extending outward from the toes. The buffer plate 8 is in the shape of an inverted U, with one side fixedly connected to the base plate 1 and the other side located on the top surface of the protective cover 3. When the buffer plate 8 is placed on the protective cover 3, materials such as steel bars will first come into contact with the buffer plate 8 when they fall from the workbench. The impact force will then be dispersed by the buffer plate 8 before falling onto the protective cover 3, avoiding direct hard contact between the protective cover 3 and the materials. This effectively improves the service life of the protective device and further enhances the safety of the equipment when facing heavy materials falling.

[0056] In this embodiment, the buffer plate 8 is made of elastic material. The buffer plate 8 made of elastic material can play a good buffering role. When materials such as steel bars fall from the workbench, the impact force is dispersed by the flexible deformation generated by the buffer plate 8.

[0057] The implementation principle of Embodiment 3 is as follows: A buffer plate 8 made of elastic material is provided on the base plate 1 extending outward from the toe. The buffer plate 8 is in the shape of an inverted U. One side of the plate is fixedly connected to the base plate 1, and the other side is located on the top surface of the protective cover 3. When the buffer plate 8 is placed on the protective cover 3, the materials such as steel bars will first come into contact with the buffer plate 8 when they fall from the workbench. Then, the impact force is dispersed by the buffer plate 8 before falling onto the protective cover 3, avoiding direct hard contact between the protective cover 3 and the materials. This effectively improves the service life of the protective device and further enhances the safety of the equipment when facing the fall of some relatively heavy materials.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
