Description

Technical Field

[0001] The present application belongs to the field of rivets, and in particular to a shock-resistant and anti-loosening rivet. Background Art

[0002] Rivets are a type of rivet used for single-sided riveting, but they must be riveted with a special rivet gun. During riveting, the rivet core is pulled by a special rivet gun to expand the rivet body and play a riveting role. This type of rivet is particularly suitable for riveting occasions where it is inconvenient to use ordinary rivets, so it is widely used in construction, automobiles, ships, aircraft, machinery, electrical appliances, furniture and other products.

[0003] The existing announcement number is CN213270626U, which discloses a high-strength closed locking rivet, including a rivet threaded rod, on which a through hole, an extension rod and a threaded sleeve are provided. The through hole is located on the left side of the inside of the rivet threaded rod, the extension rod is embedded in the left end of the rivet threaded rod, the threaded sleeve is connected to the outer surface of the right end of the rivet threaded rod through a thread, the through hole is connected to the limiting hole through a limiting pin, the right end of the threaded sleeve is provided with a baffle, the left end of the extension rod is provided with a tightening joint, and the tightening joint is provided with a cross groove and a regular hexagonal groove.

[0004] Although the above rivets increase the range of use of the locking rivets, the rivets are easily loosened by vibration after installation, which affects the locking effect of the rivets on the parts. Utility Model Content

[0005] The purpose of the present application is to provide a shock-resistant and anti-loosening rivet in response to the above-mentioned technical problems, which can prevent the rivet from loosening when it is vibrated, thereby making the rivet have a better fastening effect on parts.

[0006] The present application provides a shock-resistant and anti-loosening rivet, comprising a rivet core and:

[0007] A nail cap, which is connected and installed on the nail core;

[0008] A rivet body, wherein the rivet body is mounted on one side of the rivet cap;

[0009] A rivet sleeve, which is connected and mounted on the rivet body, and is composed of two folded parts;

[0010] A traction head, the traction head is welded on the nail sleeve;

[0011] A reinforcement component, the reinforcement component is mounted on the mandrel traction head;

[0012] Wherein, the reinforcement component includes a support block, a spherical protrusion, and a locking groove. The support block is installed on the traction head, the spherical protrusion is installed on the traction head, the other end of the spherical protrusion is connected to the nail core, and the locking groove is arranged on the rivet body.

[0013] During use, the user inserts the rivet body into the part until the part abuts against one side of the nail cap, and the nail cap provides a limit for the rivet body to prevent the rivet body from slipping off the part. The rivet gun sleeve is then connected to the outside of the nail core, and the rivet gun acts on the nail core to pull the nail core. The pulled nail core drives the pulling head to pull the nail sleeve until the two folded parts on the nail sleeve fit together and extend to limit and fix the side of the part where the nail cap is not provided. When the two baffle plates on the nail sleeve fit together and extend to complete the fixation of one side of the part, the support block and the spherical protrusion on the pulling head are also pulled and driven to be stuck in the locking groove, which can prevent the rivet from being loosened and detached from the part due to vibration, thereby making the rivet have a better fastening effect on the part.

[0014] Furthermore, the reinforcement component also includes:

[0015] Inverted teeth, the inverted teeth are mounted on the support block;

[0016] A top block is mounted on the locking groove.

[0017] The reinforcement component also includes inverted teeth and a top block. The inverted teeth are installed on the support block, and the top block is installed on the locking groove. When the support block is pulled and moved, the inverted teeth will also be pulled and moved. When the support block stops moving, several inverted teeth have been against several top blocks. The inverted teeth and the top block make it more difficult for the rivet to loosen from the part, so that the rivet has a better fastening effect on the part.

[0018] Furthermore, the rivet body comprises:

[0019] A sleeve, the sleeve being mounted on the nail cap;

[0020] A telescopic rod, wherein the telescopic rod is inserted into the sleeve;

[0021] A limiting hole, wherein the limiting hole is arranged on the telescopic rod;

[0022] A through hole, wherein the through hole is arranged on the sleeve;

[0023] A limit pin passes through the through hole and is inserted into the limit hole.

[0024] The length of the rivet body can be adjusted according to the depth of the mounting hole of the part. A plurality of limit holes are provided, and the length of the rivet body can be adjusted by extending and retracting the telescopic rod in the sleeve. When the position adjustment of the sleeve and the telescopic rod is completed and they match the mounting hole of the part, the limit pin is inserted into the through hole on the sleeve and then plugged into the limit hole corresponding to the through hole to complete the position locking of the telescopic rod and the sleeve, so that the rivet can adapt to more mounting holes of parts with different depths, making the rivet more applicable.

[0025] Furthermore, the nail cap includes:

[0026] A sealing ring, wherein the sealing ring is mounted on the nail cap;

[0027] A sponge block is installed on the sealing ring.

[0028] The nail cap includes a sealing ring and a sponge block, the sealing ring is installed on the nail cap, and the sponge block is installed on the sealing ring. The sponge block can absorb water between the rivet and the part to prevent the rivet and the part from being in a wet state, which may cause the rivet to corrode and rust and cause thread slippage. The sealing ring can prevent water from entering the part and the rivet from the nail cap, making the rivet less likely to corrode and rust.

[0029] Furthermore, the nail cap further comprises:

[0030] A rubber pad body, wherein the rubber pad body is installed on the sponge block;

[0031] A plurality of through holes are provided, and the through holes are arranged on the rubber pad body.

[0032] The nail cap also includes a rubber pad and a through hole, the rubber pad is installed on the sponge block, and the through hole is set on the rubber pad. Water between the part and the rivet can be absorbed by the sponge block through the through hole. The rubber pad can provide elastic buffering for the rivet to prevent the rivet from being impacted or vibrated when installed on the part and bumping into the part to cause damage.

[0033] Furthermore, the rubber pad is provided with anti-slip grooves.

[0034] By providing anti-skid patterns on the rubber pad, the anti-skid patterns can enhance the friction between the rubber pad and the parts, making it less likely for the rivet to be displaced or loosened when fixed on the parts, thereby improving the stability of the rivet fixed on the parts.

[0035] The beneficial effects of this application are:

[0036] 1. When the two shielding plates on the nail sleeve are extended to fit each other to fix one side of the part, the support block and the spherical protrusion on the traction head are also driven and inserted into the locking groove to prevent the rivet from being loosened and separated from the part due to vibration, so that the fastening effect of the rivet on the part is better;

[0037] 2. When the support block stops moving, several inverted teeth have been against several top blocks. The inverted teeth and top blocks make it more difficult for the rivet to loosen from the part, so that the rivet has a better fastening effect on the part;

[0038] 3. Insert the limit pin into the through hole on the sleeve and then plug it into the limit hole corresponding to the through hole to complete the position locking of the telescopic rod and the sleeve, so that the rivet can adapt to more parts installation holes of different depths, making the rivet more applicable.
