Description

Technical Field

[0001] The present application relates to the field of rivet guns, and more particularly to a trigger mechanism for a rivet gun. Background Art

[0002] A rivet gun, also known as a blind rivet gun, is a tool mainly used for blind riveting. Rivet guns are widely applicable in the manufacturing of automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, decoration, mechanical and electrical, and light industrial products. Based on different driving methods, rivet guns can generally be divided into pneumatic rivet guns, electric rivet guns, and manual rivet guns. Among them, pneumatic rivet guns with high working efficiency are widely used in factories.

[0003] Generally, a pneumatic rivet gun includes a housing, a grasping unit, a pneumatic unit, and a recycling unit. The pneumatic unit is driven to drive the grasping unit to grasp the nail rod and drive the nail rod to move to break the nail rod to complete blind riveting. Then, the pneumatic unit will also cause the recycling unit to recycle the broken nail rod at the same time.

[0004] A common type of recycling unit includes a recycling channel formed inside the housing and a collection cylinder provided at the end of the housing. The recycling channel is connected to the housing. The broken nail rod will enter the recycling channel under the action of the gas of the pneumatic unit and then enter the collection cylinder to be collected. Of course, sometimes the broken nail rod may also temporarily stay in the recycling channel.

[0005] Currently, in order to facilitate the cleaning of the nail rods in the collection cylinder, the collection cylinder and the housing are usually detachably connected. After the collection cylinder is removed, if the worker does not pay attention to the installation state of the collection cylinder and continues to use the pneumatic rivet gun to perform nail rod blind riveting or accidentally starts the rivet gun, the gas will drive the broken nail rod or the nail rod that may stay in the recycling channel to rush out from the end of the housing, which may cause harm to the user.

[0006] Therefore, how to make the rivet gun inoperable after the collection cylinder is removed to ensure the safety of the user is an urgent problem to be solved. Utility Model Content

[0007] In order to ensure that the rivet gun cannot work after the collection cylinder is removed, the present application provides a trigger mechanism for a rivet gun.

[0008] A trigger mechanism for a rivet gun provided by the present application adopts the following technical solution:

[0009] A trigger mechanism for a rivet gun includes a housing, and the housing is detachably connected with a collection cylinder; the housing is further installed with a control module, the control module is used to be connected with the rivet gun, and the control module is configured to be able to control the start / stop of the rivet gun in response to the installation / dismantling of the collection cylinder.

[0010] By adopting the above technical solution, when the collection cylinder is installed, the control module can control the rivet gun to start, and when the collection cylinder is removed, the control module can control the rivet gun to stop working; the present application can ensure that the rivet gun cannot work after the collection cylinder is removed, thereby ensuring the safety of the user.

[0011] In a specific feasible implementation, the control module is configured to be physically pressable; when the collection cylinder is not removed, the control module is pressed by the collection cylinder, and the control module controls the rivet gun to work; when the collection cylinder is removed, the collection cylinder releases the pressing on the control module, and the control module controls the rivet gun to stop working.

[0012] By adopting the above technical solution, when the collection cylinder is installed, the collection cylinder physically presses the control module, and at this time the control module controls the rivet gun to work; while when the collection cylinder is removed, the control module is not physically pressed, and the control module will control the rivet gun to stop working.

[0013] In a specific feasible implementation, the control module includes a module body and a force-receiving member for being pressed by the collection cylinder. The module body is installed in the housing, the force-receiving member is installed on the module body, and the force-receiving member is configured to be able to move reciprocally; a pressing member is provided on the outer wall of the force-receiving member, and an elastic member is provided between the pressing member and the module body. One end of the elastic member is connected to the pressing member, and the other end of the elastic member is connected to the module body. The force-receiving member is configured to be able to move under the action of the elastic member after the collection cylinder is removed, so as to control the rivet gun to stop working.

[0014] By adopting the above technical solution, when the collection cylinder presses the force-receiving member, the elastic member is in a compressed state; after the collection cylinder is removed, the force-receiving member will move under the elastic force of the elastic member, and at this time the rivet gun stops working.

[0015] In a specific feasible implementation, the elastic member is a spring.

[0016] By adopting the above technical solution, the spring has good elastic deformation ability.

[0017] In a specific feasible implementation, the connection between the collection cylinder and the housing is a threaded connection.

[0018] By adopting the above technical solution, the collection cylinder can be rotated to be removed or installed.

[0019] In a specific feasible implementation, a limiting member is further provided on the outer wall of the collection cylinder, and the limiting member is configured to be able to abut against the housing to limit the distance that the collection cylinder is screwed into the housing.

[0020] By adopting the above technical solution, the limiting member can prevent the collection cylinder from being screwed too deep into the housing, which may cause the pressed force-receiving member to move out of position.

[0021] In a specific feasible implementation, the outer wall of the collection cylinder has concave patterns.

[0022] By adopting the above technical solution, it is convenient for the user to grasp the collection cylinder for rotation.

[0023] In a specific feasible implementation, the end of the collection cylinder away from the housing has a chamfer.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. When the collection cylinder is installed, the control module can control the rivet gun to start, and when the collection cylinder is removed, the control module can control the rivet gun to stop working; the present application can ensure that the rivet gun cannot work after the collection cylinder is removed, thus ensuring the safety of the user.

[0026] 2. When the collection cylinder presses the force-receiving member, the elastic member is in a compressed state; after the collection cylinder is removed, the force-receiving member will move under the elastic force of the elastic member, and at this time the rivet gun stops working.

[0027] 3. The limiting member can prevent the collection cylinder from being screwed too deep into the housing, which may cause the pressed force-receiving member to move out of position, and the concave patterns can facilitate the user to grasp the collection cylinder for rotation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following further describes the present application in detail with reference to the drawings.

[0033] An embodiment of the present application discloses a rivet gun trigger mechanism, which is used to ensure that the rivet gun cannot work after the collection cylinder 2 is removed to guarantee the safety of the user.

[0034] Refer to Figure 1 and Figure 2 For the pull - rivet gun trigger mechanism, it includes a housing 1. The housing 1 is detachably connected to a collection cylinder 2. Specifically, the connection between the housing 1 and the collection cylinder 2 is a threaded connection. The housing 1 is also equipped with a control module 3. The control module 3 is used to connect to the pull - rivet gun. The control module 3 can respond to the installation / detachment of the collection cylinder 2 to control the start / stop of the pull - rivet gun. Specifically, the control module 3 can be physically pressed. When the collection cylinder 2 is not detached, the control module 3 is pressed by the collection cylinder 2, and the control module 3 will control the pull - rivet gun to work. When the collection cylinder 2 is detached, the collection cylinder 2 releases the pressure on the control module 3, and the control module 3 will control the pull - rivet gun to stop working. The control module 3 controls the start / stop of the pull - rivet gun generally by controlling the on / off of the air passage in the pneumatic unit. The specific control method is prior art and will not be elaborated here.

[0035] After the collection cylinder 2 is installed, the control module 3 controls the pull - rivet gun to start. At this time, the gas will drive the nail rod to move into the collection cylinder 2. After the collection cylinder 2 is detached, the control module 3 controls the pull - rivet gun to stop working.

[0036] Refer to Figure 2 and Figure 3 The control module 3 includes a module body 31 and a force - receiving member 32 for being pressed by the collection cylinder 2. The module body 31 is installed in the housing 1, the force - receiving member 32 is installed on the module body 31. The module body 31 has an installation hole 311, and the force - receiving member 32 is installed in the installation hole 311. The force - receiving member 32 can move reciprocally left and right. There is a pressing member 321 on the outer wall of the force - receiving member 32. There is an elastic member 33 between the pressing member 321 and the module body 31. One end of the elastic member 33 is connected to the pressing member 321, and the other end of the elastic member 33 is connected to the module body 31. The elastic member 33 is a spring. When the collection cylinder 2 is installed on the housing 1, the spring is in a compressed state. The force - receiving member 32 can move left under the action of the spring after the collection cylinder 2 is detached to control the pull - rivet gun to stop working. The specific circuit structure inside the control module 3 body is prior art and will not be elaborated here.

[0037] Refer to Figure 2 and Figure 3 To prevent the collection cylinder 2 from being screwed into the housing 1 too deeply, which may cause the pressed force - receiving member 32 to move out of position and damage the structure of the module body 31, a limiting member 21 is also provided on the outer wall of the collection cylinder 2. The limiting member 21 is a limiting ring in this embodiment. The limiting member 21 can move right to abut against the housing 1 to limit the distance that the collection cylinder 2 is screwed into the housing 1.

[0038] Refer to Figure 1 and Figure 2, in order to facilitate the user to grasp the collection cylinder 2 for rotation, the outer wall of the collection cylinder 2 has concave patterns 22; in order to ensure the operation safety of the user for the collection cylinder 2, one end of the collection cylinder 2 away from the housing 1 has a chamfer 23.

[0039] The implementation principle of a trigger mechanism of a rivet gun according to an embodiment of the present application is as follows: rotate the collection cylinder 2 to detach the collection cylinder 2. At this time, the collection cylinder 2 releases the pressing on the force-receiving member 32, the spring extends, the force-receiving member 32 moves leftward, and the control module 3 controls the rivet gun to stop working.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
