Description

Technical Field

[0001] The utility model relates to the field of riveting power tools, and particularly relates to a riveting nozzle for a rivet gun and a rivet gun. Background Art

[0002] At present, the riveting nozzle hole of the riveting power tool gun head on the market is only used as a nail inlet hole for a rivet to pass through freely. Whether before or after riveting, the broken tail pin is not restricted by the riveting nozzle. Before riveting, if the gun head of the rivet gun is downward, the rivet will fall off in a free state after being inserted into the riveting nozzle, and the user needs to hold it all the time to prevent the rivet from falling off. Such a riveting nozzle is not suitable for use at high altitudes or in some special occasions. After the rivet is riveted, the tail pin also falls forward or backward freely with the state of the gun body, which is not conducive to the collection of waste tail pins. At present, there is a kind of riveting power tool that adds a structure in the riveting nozzle that can clamp the tail of the rivet to prevent it from falling off after inserting the nail; however, when the nail tail breaks, the tail pin will still be clamped at the position of the riveting nozzle, and the broken tail pin needs to be manually pulled out or inserted into the riveting nozzle to smoothly insert the next rivet; this brings great trouble to the riveting work and greatly affects the riveting efficiency. Summary of the Invention

[0003] Therefore, it is necessary to provide a riveting nozzle for a rivet gun and a rivet gun that can clamp the rivet before riveting to prevent it from falling off; after riveting, it can prevent the rivet from falling off from the front end of the rivet gun and is convenient for collecting the tail pin.

[0004] To achieve the above object, the inventor provides a riveting nozzle for a rivet gun, including: a riveting nozzle body, a pin is provided on the side wall of the riveting nozzle body, one end of the pin extends into the nail inlet hole of the riveting nozzle body, and a reset member is provided at the other end of the pin.

[0005] As a preferred structure of the utility model, one end of the pin located in the nail inlet hole of the riveting nozzle body, the side away from the nail inlet end is a vertical surface, or a first inclined surface that inclines towards the rear end of the nail inlet hole and extends.

[0007] As a preferred structure of the utility model, the reset member is provided on the periphery of the riveting nozzle body, and the reset member is elastically connected to the other end of the pin.

[0008] As a preferred structure of the utility model, the reset member is an O-ring, the other end of the pin extends out of the riveting nozzle body, and the O-ring is sleeved on the end of the pin extending out of the riveting nozzle body.

[0009] As a preferred structure of the present utility model, a clamping groove is provided at the end of the pin located at one end of the outer side wall of the riveting nozzle body, and the O-ring is sleeved in the clamping groove.

[0010] As a preferred structure of the present utility model, there are two pins, and the two pins are symmetrically arranged on the side wall of the riveting nozzle body.

[0011] To achieve the above object, the inventor also provides a rivet gun, which includes a transmission mechanism, a riveting assembly, a clamping jaw and a clamping jaw sleeve, and further includes: the riveting nozzle for the rivet gun described in any one of the above invention contents, the transmission mechanism is in transmission connection with the riveting assembly, the riveting assembly is in transmission connection with the clamping jaw sleeve, the clamping jaw sleeve is sleeved on the periphery of the clamping jaw, and the riveting nozzle body is arranged at the front end of the clamping jaw.

[0015] Different from the prior art, the beneficial effects achieved by the above technical solution are as follows: By setting a special riveting nozzle structure, that is, a pin is arranged on the side wall of the riveting nozzle body, and through the self-resetting pin structure, when inserting a rivet through the riveting hole of the riveting nozzle, the pin can clamp the rivet, so that there is no need to hold the rivet by hand before riveting, nor to worry about the rivet falling out, which effectively facilitates the riveting operation of the rivet gun, especially suitable for use in high-altitude and some special occasions. In addition, after the rivet is broken during riveting, the tail pin is blocked by the pin of the riveting nozzle and stays in the conduit. During continuous riveting operations, the newly generated tail pin knocks on the end of the previous tail pin by borrowing the rivet-breaking force, so that the previous tail pin is impacted into the nail collection barrel, and thus it can cycle repeatedly to produce the effect of always automatically collecting nails.

[0024] To describe in detail the technical content, structural features, achieved objectives and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and with reference to the accompanying drawings.

[0025] As Figure 1 and Figure 2 shown, this embodiment provides a riveting nozzle for a rivet gun, including: a riveting nozzle body 1, a pin 102 is provided on the side wall of the riveting nozzle body 1, one end of the pin 102 extends into the nail feeding hole of the riveting nozzle body 1, and a reset member is provided at the other end of the pin. In this embodiment, by setting a special pin 102 structure on the riveting nozzle body, when inserting a rivet, the pin 102 moves outward along the installation direction of the pin under the push of the rivet. Until the rivet is inserted to the position, the pin tightens the rivet under the action of the reset member, thus avoiding the situation of the rivet falling off after inserting the rivet; during the riveting process, the claw grabs the tail pin of the rivet and moves backward, and breaks the rivet, and continues to move backward until the tail pin passes through the pin and moves to the rear end of the pin. At this time, after the breaking action is completed, the tail pin moves forward. During the movement, the tail pin will first contact the pin and be blocked by the pin. At this time, the tail pin will not be able to pass through the block of the pin and will be intercepted. During this process, the tail pin will not be pushed out of the pin. After the rivet gun runs and resets continuously, the claw will release the tail pin, and the tail pin will be blocked by the riveting nozzle structure and stay in the conduit; repeating this process, the tail pin will be impacted by the impact force generated by the fracture of the next riveted tail pin and enter the rear nail collection barrel, completing the collection of the tail pin.

[0026] As Figure 2 and Figure 4As shown, in this embodiment, one end of the pin located in the nail feeding hole 101 of the riveting nozzle body 1 has a vertical surface 103 on the side away from the nail feeding end, or a first inclined surface that extends obliquely towards the rear end of the nail feeding hole. By setting the vertical surface or the outwardly extending first inclined surface, it can effectively prevent the tail pin from being ejected from the pin after the needle breaks, thus causing obstruction to subsequent pin insertion. In addition, in this embodiment, one end of the pin located in the nail feeding hole of the riveting nozzle body has a second inclined surface 104 that is inclined inwards near the nail feeding end; the setting of the second inclined surface 104 effectively facilitates the insertion of the rivet. When inserting the rivet, the end of the rivet abuts against the second inclined surface 104. Under the combined action of the pushing force and the second inclined surface, the pin retracts along the installation direction, and the rivet can be smoothly inserted in place.

[0027] As Figure 3 and Figure 4 shown, the resetting member is arranged on the peripheral side of the riveting nozzle body, and the resetting member is elastically connected to the other end of the pin. In the embodiment, the resetting member is an O-ring 106. The other end of the pin extends out of the riveting nozzle body, and the O-ring 106 is sleeved on the end of the pin extending out of the riveting nozzle body 1; and in this embodiment, a clamping groove 105 is provided at the end of the pin located at one end of the outer side wall of the riveting nozzle body, and the O-ring 106 is fixed to the end of the pin by being sleeved in the clamping groove 105; when inserting the rivet, the pin 102 retracts, and the O-ring 106 expands outwards; after the riveting is completed, under the action of the O-ring 106, the pin 102 resets to block the nail feeding hole of the riveting nozzle body. Of course, in different embodiments, the resetting member can also be an elastic ring, a wire ring, a reset spring, etc., which can enable the pin to reset after retracting.

[0028] In the above embodiment, two pins 102 are provided, and the two pins are symmetrically arranged on the side wall of the riveting nozzle body; the setting of the two pins can achieve the purpose of saving space while clamping the rivet and blocking the nail feeding hole.

[0029] As Figure 5 and Figure 6As shown, this embodiment further provides a rivet gun, including a transmission mechanism 201, a rivet assembly 202, a clamp 203 and a clamp sleeve 204, and also includes: a rivet gun rivet nozzle as described in any one of the above embodiments, the transmission mechanism 201 is connected to the rivet assembly 202, the rivet assembly 202 is connected to the clamp sleeve 204, the clamp sleeve 204 is sleeved on the side of the clamp, and the rivet nozzle body 1 is arranged at the front end of the clamp 203. The rivet nozzle body 1 of this embodiment is arranged at the front end of the clamp 203, so that after the rivet is inserted, the pin clamps the rivet to prevent the rivet from falling, and the rivet passing through the nail hole 101 can be grabbed by the clamp, and under the action of the transmission mechanism 201, the rivet assembly 202 and the clamp sleeve 204, the clamp 203 grabs the rivet to realize the rivet operation, and the tail pin after the broken nail is blocked in the channel by the pin. In this embodiment, the rivet assembly 202 includes a lead screw nut and a lead screw that are transmission-connected to the transmission mechanism. The lead screw nut is sleeved on the lead screw. The front end of the lead screw can be directly connected to the rear end of the clamping jaw sleeve, or a connecting rod can be provided to connect the lead screw to the clamping jaw sleeve. When the transmission mechanism is working, the lead screw nut is driven to rotate, thereby driving the lead screw to move backward. During the movement, the clamping jaw sleeve is pulled backward, thereby forcing the claws of the clamping jaw to gradually close and bite the rivet to achieve the riveting operation. After the riveting is completed, the driving mechanism rotates, and the lead screw is rotated through the transmission mechanism, driving the clamping jaw sleeve to reset. The clamping jaw is reset again under the action of the reset spring to prepare for the next riveting operation.

[0030] like Figure 5 and Figure 6 As shown, in order to avoid fixing the rivet mouth body, the present embodiment further includes a sleeve 205, which is sleeved on the outside of the clamping jaw sleeve 204. The sleeve 205 can be fixedly connected to the outer shell of the rivet gun, and the rivet mouth body and the sleeve are movably and detachably connected. Specifically, interference fit, clamp, thread and other connection methods can be adopted. In the present embodiment, it is a threaded connection.

[0031] In this embodiment, the pin 102 can be arranged on the side wall of the rivet mouth body outside the front end of the sleeve; or, by providing an inwardly sunken step 206 on the front end surface of the sleeve, the pin is arranged on the side wall of the rivet mouth body inside the sunken step.

[0032] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described herein, or equivalent structural or equivalent process transformations made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the scope of patent protection of the utility model.
