Description

Technical Field

[0001] This utility model relates to the field of bolt technology, and in particular to a bolt and a heat treatment device for bolts. Background Technology

[0002] A bolt is a common fastener consisting of a cylindrical metal rod with helical threads and a nut. The bolt and nut engage to fasten two or more parts together.

[0003] In existing bolt applications, a washer is first wound around the bolt, then the bottom end of the bolt passes through the object being fixed, and then the nut is threaded onto the bottom end of the bolt. The user then rotates the bolt, which, in conjunction with the nut, tightens the object. As the bolt rotates and tightens, the washer and nut first contact the upper and lower end faces of the object being fixed. Using the first and second anti-loosening spikes, the friction between the nut / wasp and the object being fixed is increased. As the bolt continues to penetrate deeper, the slidable limiting block inside the second cavity contacts the limiting groove on the inner side of the washer. Because one side of the limiting block is designed to be inclined, when the bolt rotates clockwise, it is squeezed by the limiting groove and retracts into the second cavity, without affecting the rotation of the bolt, thus allowing the bolt body to be tightened. However, while existing bolts use the limiting block to fix the washer, this device does not mention a reset structure for the limiting block. If relying solely on gravity or material elasticity, the limiting block may not be able to spring into the limiting groove in time during vibration, and the anti-loosening mechanism may be "lagging" or ineffective.

[0004] Therefore, it is necessary to provide a new type of bolt and a heat treatment device for bolts to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a bolt and a heat treatment device for bolts.

[0006] This utility model provides a bolt including a stud and a nut. A fixing block is fixedly connected to the top of the stud, and a washer is threadedly connected to the outer surface of the stud. A pushing block is slidably connected to the inner wall of a groove on one side wall of the fixing block. Two connecting brackets are slidably connected to both sides of one end of the pushing block. The two connecting brackets are slidably connected to the inner wall of the groove on the fixing block, and a fixing strip is fixedly connected to the end of each connecting bracket away from the pushing block. Two compression springs are fixedly connected to one end of the fixing strip. The ends of the two compression springs away from the fixing strip are fixedly connected to the inner wall of the groove on one side of the fixing block. A locking plate is fixedly connected to the end of the fixing strip away from the compression springs. The nut is threadedly connected to the outer surface of the stud.

[0007] Preferably, the top of the gasket is fixedly connected to two limiting frames.

[0008] Preferably, a limiting strip is slidably connected to the inner wall of the groove on the pushing block, and the limiting strip is fixedly connected to one side wall of the fixing block.

[0009] Preferably, the end of the gasket away from the fixing block is provided with a plurality of first anti-loosening spikes.

[0010] Preferably, the nut is provided with a plurality of second anti-loosening spikes at both the upper and lower ends.

[0011] The second aspect of this utility model provides a heat treatment device for bolts, including the bolts, a housing and several trays. A switch door is hinged to one side wall of the housing, and a handle is fixedly connected to one end of the switch door. Several trays are slidably connected to the inner wall of the housing, and the bolts are disposed on the top of the trays.

[0012] Compared with related technologies, the bolt and bolt heat treatment equipment provided by this utility model have the following beneficial effects:

[0013] This utility model provides a bolt in which a washer is first wrapped around the outer surface of the stud. Then, when the washer moves to the bottom of the stud, a push block is pressed. The push block drives the fixing block and the locking block through the connecting frame, and compresses the compression spring until the washer moves to the inner wall of the groove on the fixing block. At this point, the push block is released. Since the squeezing force generated by the push block is no longer present, the washer will move towards the limiting frame under the elastic force of the compression spring, thereby fixing the limiting frame. This device reduces the probability that the limiting block may not be able to spring into the limiting groove in time during vibration, and the anti-loosening mechanism may be "lagging" or fail.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 ,in, Figure 1 A schematic diagram of the structure of a bolt provided by this utility model; Figure 2 This is a cross-sectional structural diagram provided by the present invention; Figure 3 A schematic diagram of the structure of the gasket and the push block provided by this utility model; Figure 4 A schematic diagram of the structure of the push block and the fixing strip provided by this utility model; Figure 5 This is a schematic diagram of the structure of a heat treatment device for bolts provided by this utility model.

[0022] In the specific implementation process, such as Figures 1 to 5 As shown, a fixing block 3 is fixedly connected to the top of the stud 1, and a washer 4 is threadedly connected to the outer surface of the stud 1. A push block 5 is slidably connected to the inner wall of the groove opened on one side wall of the fixing block 3. Two connecting brackets 6 are slidably connected to both sides of one end of the push block 5. The two connecting brackets 6 are slidably connected to the inner wall of the groove opened on the fixing block 3. A fixing strip 7 is fixedly connected to the end of the two connecting brackets 6 away from the push block 5. Two compression springs 8 are fixedly connected to one end of the fixing strip 7. The ends of the two compression springs 8 away from the fixing strip 7 are fixedly connected to the inner wall of the groove opened on one side of the fixing block 3. A locking plate 9 is fixedly connected to the end of the fixing strip 7 away from the compression springs 8. The nut 2 is threadedly connected to the outer surface of the stud 1. Two limiting frames 10 are fixedly connected to the top of the washer 4. A limiting strip 11 is slidably connected to the inner wall of the groove opened on the push block 5. The limiting strip 11 is fixedly connected to one side wall of the fixing block 3. Several first anti-loosening spikes 12 are provided at the end of the washer 4 away from the fixing block 3. Several second anti-loosening spikes 13 are provided at both the upper and lower ends of the nut 2.

[0023] In use, the washer 4 is first wrapped around the outer surface of the stud 1. Then, when the washer 4 moves to the bottom of the stud 1, the push block 5 is pressed. The push block 5 will drive the fixing block 3 and the locking block to move through the connecting bracket 6 and compress the compression spring 8 until the washer 4 moves to the inner wall of the groove opened on the fixing block 3. At this time, the push block 5 is released. Since the squeezing force generated by the push block 5 is lost, it will move towards the limit frame 10 under the elastic force of the compression spring 8, thereby fixing the limit frame 10.

[0024] The second aspect of this utility model provides a heat treatment device for bolts, including bolts, a housing 14 and several trays 15. A switch door 16 is hinged to one side wall of the housing 14, and a handle 17 is fixedly connected to one end of the switch door 16. Several trays 15 are slidably connected to the inner wall of the housing 14, and bolts are set on the top of the trays 15.

[0025] The working principle of this utility model is as follows: In use, the washer 4 is first wrapped around the outer surface of the stud 1. Then, when the washer 4 moves to the bottom of the stud 1, the push block 5 is pressed. The push block 5 will drive the fixed block 3 and the locking block to move through the connecting frame 6 and compress the compression spring 8 until the washer 4 moves to the inner wall of the groove opened on the fixed block 3. At this time, the push block 5 is released. Since the squeezing force generated by the push block 5 is lost, it will move towards the limit frame 10 under the elastic force of the compression spring 8, thereby fixing the limit frame 10.
