Description

Technical Field

[0001] This utility model belongs to the technical field of rebar caulking guns, specifically relating to a composite adhesive syringe structure for concrete rebar installation. Background Technology

[0002] The rebar caulking gun is a special tool used in construction engineering for injecting rebar adhesive (chemical anchoring agent). It is mainly used for injecting adhesive when rebar is inserted into concrete structures. In concrete rebar installation, the injection accuracy and efficiency of the composite adhesive directly affect the quality of rebar installation.

[0003] Existing manual or pneumatic rebar caulking guns cannot accurately control the injection pressure and speed, which can easily lead to flow interruption or over-injection. Furthermore, the lack of radial limit on the push rod causes deviation in the movement trajectory, resulting in uneven material output and reducing the working efficiency and quality of the rebar caulking gun. Utility Model Content

[0004] The purpose of this utility model is to provide a composite adhesive injector structure for concrete rebar installation, which aims to solve the problems of existing rebar caulking guns where manual or pneumatic drive cannot accurately control the injection pressure and speed, easily leading to flow interruption or over-injection, and the lack of radial limit on the push rod causing deviation in the movement trajectory and uneven material output, thus reducing the working efficiency and quality of the rebar caulking gun.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A composite adhesive injector structure for concrete rebar installation includes:

[0007] case;

[0008] A handle is fixedly connected to the lower end of the housing, and a switch is fixedly connected to one side of the handle. A mounting bracket is rotatably connected to the upper end of the housing via a rotating shaft.

[0009] Two sliding rods, one end of each sliding rod movably penetrates the inner surface of the housing, one end of each sliding rod is fixedly connected to a pressing plate, and a support base is fixedly connected to the circumferential surface of each sliding rod;

[0010] A fixing block, which is fixedly connected to the other end of two sliding rods, and the upper end of each fixing block is rotatably connected to two connecting plates via a rotating shaft; and

[0011] A sliding mechanism is provided, which is disposed in the mounting frame and connected to two connecting plates to drive the two connecting plates to slide.

[0012] As a preferred embodiment of this utility model, the sliding mechanism includes:

[0013] The motor is fixedly connected to the inner wall of one side of the mounting frame. The outer surface of the motor is provided with a protective shell. The output end of the motor is fixedly connected to a lead screw. One end of the lead screw is rotatably connected to the inner wall of the other side of the mounting frame. A nut is threaded onto the circumferential surface of the lead screw.

[0014] A connecting component, which is disposed within a mounting bracket to connect two connecting plates.

[0015] As a preferred embodiment of this utility model, the connecting component includes:

[0016] Two limiting rods are fixedly connected to the inner surface of the mounting bracket. Limiting blocks are slidably connected to the circumferential surfaces of the two limiting rods. The adjacent ends of the two limiting blocks and the two sides of the nut are fixedly connected respectively. The upper ends of the two limiting blocks and the lower ends of the two connecting plates are fixedly connected respectively.

[0017] As a preferred embodiment of this utility model, the upper end of the housing has two snap-fit ​​grooves, and the lower end of the mounting bracket is fixedly connected to two snap-fit ​​blocks, with the outer surfaces of the two snap-fit ​​blocks and the inner surfaces of the two snap-fit ​​grooves being slidably connected respectively.

[0018] As a preferred embodiment of this utility model, the lower end of the mounting bracket has two sliding grooves, the inner surfaces of the two sliding grooves are slidably connected to sliding blocks, the lower ends of the two sliding blocks are fixedly connected to fixed seats, and the lower ends of the fixed seats are fixedly connected to two limiting shells.

[0019] In a preferred embodiment of this utility model, a placement seat is fixedly connected to the inner surface of the housing, and two protective pads are provided on the inner surface of the placement seat.

[0020] As a preferred embodiment of this utility model, the inner surface of the housing is threadedly connected to a mounting base, one side of the mounting base is fixedly connected to a conical seat, and the outer surface of the conical seat is threadedly connected to a conical shell.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. In this solution, a trigger switch starts the motor to drive the lead screw to rotate. The rotation of the lead screw drives the threaded nut to move horizontally along the axis of the lead screw. The movement of the nut simultaneously pushes the limit blocks fixed on both sides. The limit blocks slide along the surface of the limit rod to ensure that the movement trajectory is not deviated. When the two limit blocks slide to the left, they drive the two connecting plates to slide, thereby driving the fixed block and the two fixed sliding rods to slide, which in turn pushes the two extrusion plates forward, squeezing the adhesive container in the placement seat. This forces the adhesive to be injected into the rebar hole through the injection nozzle installed inside the conical seat. The rebar glue gun is driven and controlled by a motor to achieve stepless adjustment of the injection speed, solving the problem of uneven manual operation, strengthening the limiting force of the push rod, eliminating injection deviation, ensuring a constant output, and improving the working efficiency and quality of the rebar glue gun.

[0023] 2. In this solution, the placement seat is fixed to the inner surface of the housing to hold the adhesive container. At the same time, two protective pads are set on the inner surface of the placement seat to buffer the vibration of the container and prevent it from shifting during operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figure 1-4 The present invention provides the following technical solution:

[0033] A composite adhesive injector structure for concrete rebar installation includes:

[0034] Casing 1;

[0035] Handle 2 is fixedly connected to the lower end of housing 1. A switch 3 is fixedly connected to one side of handle 2. A mounting bracket 4 is rotatably connected to the upper end of housing 1 via a rotating shaft.

[0036] Two sliding rods 23, one end of each sliding rod 23 movably penetrates the inner surface of the housing 1, one end of each sliding rod 23 is fixedly connected to a pressing plate 22, and a support base 14 is fixedly connected to the circumferential surface of each sliding rod 23.

[0037] Fixed block 13 is fixedly connected to the other end of two sliding rods 23. The upper end of each fixed block 13 is rotatably connected to two connecting plates 12 via a rotating shaft.

[0038] A sliding mechanism is installed inside the mounting frame 4 and connected to the two connecting plates 12 to drive the two connecting plates 12 to slide.

[0039] In a specific embodiment of this utility model, the housing 1 serves as the main support structure, bearing all other components and providing internal space to accommodate the adhesive and transmission parts. The handle 2 is fixed to the lower end of the housing 1 for the operator to grip and stably operate the syringe. The switch 3 is fixed to one side of the handle 2 and is used to control the start and stop of the motor 24, triggering the injection operation. The mounting bracket 4 is rotatably connected to the upper end of the housing 1 via a rotating shaft, supporting the sliding mechanism and allowing its angle adjustment relative to the housing 1. One end of each of the two sliding rods 23 extends through the inner surface of the housing 1, transmitting external driving force to the interior. The support seat 14 on their circumferential surface reinforces the sliding rods 23 within the housing. The motion stability within the housing 1 is achieved by fixing two extrusion plates 22 and two sliding rods 23, which penetrate one end of the housing 1, directly contacting and pushing the adhesive to achieve the injection function. Two support seats 14 are fixed to the circumferential surface of the sliding rods 23, limiting the radial offset of the sliding rods 23 and ensuring linear motion accuracy. A fixing block 13 connects the other ends of the two sliding rods 23, integrating their motion trajectories and ensuring synchronized movement. Two connecting plates 12 are rotatably connected to the upper end of the fixing block 13 via a rotating shaft, converting the linear motion of the sliding mechanism into the pushing and pulling force of the fixing block 13. The motor 24 is fixed to the inner wall of one side of the mounting bracket 4. The motor 24 is provided with rotational power output, while the protective shell 5 covers the outer surface of the motor 24 to prevent external impact damage and isolate operating noise. One end of the lead screw 6 is connected to the output end of the motor 24, and the other end is rotatably connected to the inner wall of the mounting bracket 4, converting the rotational motion of the motor 24 into linear transmission. Simultaneously, the nut 8 is threaded onto the circumferential surface of the lead screw 6, converting the rotational motion of the lead screw 6 into its own linear displacement. It is fixed to the inner surface of the mounting bracket 4 by two limiting rods 7, providing a sliding track for the limiting block 9 and restricting its rotational freedom. The two limiting blocks 9 slide on the surfaces of the two limiting rods 7, with their near ends fixedly connected to both sides of the nut 8, thus controlling the rotational motion of the lead screw 6. The linear motion of the mother 8 is transmitted to the connecting plate 12, thereby controlling the left and right sliding of the two connecting plates 12, completing the position adjustment of the two sliding rods 23, and thus squeezing the inside of the adhesive. The rebar glue gun is driven and controlled by the motor 24 to achieve stepless adjustment of the injection speed, solving the problem of uneven manual operation, strengthening the limiting force of the push rod, eliminating injection deviation and ensuring constant output, thus improving the working efficiency and quality of the rebar glue gun. It should be noted that the specific model of motor 24 used shall be selected by relevant personnel skilled in the art, and the above-mentioned motor 24 and other related information are all existing technologies, which will not be elaborated in this solution.

At the same time, the protective shell 5 covers the outer surface of the motor 24 to prevent external impact from damaging the motor 24 and to isolate operating noise. One end of the lead screw 6 is connected to the output end of the motor 24, and the other end is rotatably connected to the inner wall of the mounting bracket 4, converting the rotational motion of the motor 24 into a linear transmission base. Meanwhile, the nut 8 is threaded to the circumferential surface of the lead screw 6, converting the rotational motion of the lead screw 6 into its own linear displacement. It is fixed to the inner surface of the mounting bracket 4 by two limiting rods 7, providing a sliding track for the limiting block 9 and restricting its rotational freedom. At the same time, the two limiting blocks 9 slide on the surfaces of the two limiting rods 7, and their near ends are fixedly connected to both sides of the nut 8, transmitting the linear motion of the nut 8 to the connecting plate 12, thereby controlling the left and right sliding of the two connecting plates 12, completing the position adjustment of the two sliding rods 23, and thus squeezing the inside of the adhesive.

[0048] In this embodiment: two snap-fit ​​slots 15 are opened on the upper end of the housing 1, which cooperate with the snap-fit ​​block 16 to realize the quick positioning and installation of the mounting bracket 4. At the same time, the two snap-fit ​​blocks 16 are fixed to the lower end of the mounting bracket 4, and by sliding into the snap-fit ​​slots 15, the mounting bracket 4 is securely connected to the housing 1.

[0049] Please refer to the details.

[0050] In this embodiment: two sliding grooves 25 are formed at the lower end of the mounting frame 4 to accommodate the sliding block 26 and guide its directional sliding. The two sliding blocks 26 are slidably connected in the sliding grooves 25, dynamically connecting the fixed seat 10 and the mounting frame 4, allowing for fine adjustment of the injection angle. The two fixed seats 10 are fixed at the lower end of the sliding block 26, supporting the limiting shell 11 and transmitting the motion force.

[0051] Please refer to the details. Figure 3 The inner surface of the housing 1 is fixedly connected to a placement seat 20, and the inner surface of the placement seat 20 is provided with two protective pads 21.

[0052] In this embodiment: the placement seat 20 is fixed to the inner surface of the housing 1 to hold the adhesive container, and two protective pads 21 are provided on the inner surface of the placement seat 20 to buffer the vibration of the container and prevent it from shifting during operation.

[0055] The working principle and usage process of this utility model are as follows: First, the container containing the composite adhesive is placed in the placement seat 20 inside the housing 1. The container is fixed and buffered by the protective pad 21. The mounting bracket 4 is fixed to the housing 1 by slidingly engaging the snap-fit ​​block 16 with the snap-fit ​​groove 15 at the upper end of the housing 1. The operator holds the handle 2 and triggers the switch 3 to start the motor 24 to drive the lead screw 6 to rotate. The rotation of the lead screw 6 drives the threaded nut 8 to move horizontally along the axis of the lead screw 6. The movement of the nut 8 simultaneously pushes the limit blocks 9 fixedly connected on both sides. The limit blocks 9 slide along the surface of the limit rod 7 to ensure that the movement trajectory is not deviated. While the two limit blocks 9 slide to the left, they drive the two connecting plates 12 to slide, thereby driving the fixed block 13 and the two fixed sliding rods 23 to slide, which in turn pushes the two extrusion plates 22 forward, squeezing the adhesive container in the placement seat 20 and forcing the adhesive to be injected into the rebar hole through the injection nozzle installed inside the conical seat 18.
