[0017] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] The first embodiment of the present application is:

[0019] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the fastener mold of the first embodiment of the utility model. Figure 2 It is a structural schematic diagram of a buffer component of the first embodiment of the utility model.

[0020] The fastener mold of the utility model includes a base 101, a tensile machine body 102, a column 103, a top plate 104, a sleeve 105, a protective cover 106, a connecting block 107, a screw 108, a drive motor 109, a fixing seat 110, a damper 111, a buffer plate 112, and a buffer spring 113, which solves the problem that after the fastener breaks, fragments will splash, and the prior art does not have a protective device, which easily causes injuries to workers. It is understandable that the above solution can also be used to improve safety.

[0021] In this embodiment, the base 101 is a rectangular body, which plays a role of stable support. The tensile machine body 102 is a prior art, which is installed on the top surface of the base 101 and is used to perform a breaking test on the fasteners. The protective component is installed on the base 101, thereby solving the problem that after the fasteners break, fragments will fly, and the prior art does not have a protective device, which can easily cause injuries to workers.

[0022] The column 103 is fixedly connected to the base 101 and is located on a side of the base 101 close to the tensile machine body 102. The top plate 104 is fixedly connected to the column 103 and is located at an end of the column 103 away from the base 101. The sliding sleeve 105 is sleeved on the outside of the column 103 and is slidably connected to the column 103. The protective cover 106 is fixedly connected to the sliding sleeve 105 and is covered on the outside of the tensile machine body 102. The buffer member is installed on the protective cover 106. The driving member drives the protective cover 106 to move. The column 103 is a smooth cylinder, four in number, which are vertically arranged at the four corners of the base 101 respectively. The sliding sleeve 105 has a matching with the column 103. Through hole, the sliding sleeve 105 is installed on the column 103 through the through hole, and can slide on the column 103 to guide the movement of the protective cover 106. The protective cover 106 is a hollow rectangular cover, which can cover the outside of the tensile machine body 102 during testing. The buffer components are four groups, which are respectively arranged on the inner walls of the protective cover 106, which can buffer the flying debris. The driving component is used to drive the protective cover 106 to rise and fall. By setting the protective cover 106, the flying debris can be blocked and the kinetic potential energy of the debris is reduced, thereby ensuring the safety of the staff, and solving the problem that the fragments will fly after the fastener breaks, and the prior art does not have a protective device, which is easy to cause injuries to the staff.

[0023] Secondly, the connecting block 107 is fixedly connected to the protective cover 106 and is located on a side of the protective cover 106 close to the sliding sleeve 105; the screw 108 is rotatably connected to the top plate 104 and is threadedly connected to the connecting block 107; the driving motor 109 is installed on the top plate 104, and the output shaft of the driving motor 109 is fixedly connected to the screw 108, and the connecting block 107 is fixed to the outside of the protective cover 106 by bolts, and a mounting hole is provided on the top plate 104, and the screw 108 passes through the mounting hole and is connected to the top plate 104 through a bearing, and the connecting block 107 has a threaded through hole, and the screw 108 passes through the threaded through hole and is threadedly connected to the connecting block 107, and the driving motor 109 is fixed to the top plate 104 by bolts, and is used to drive the screw 108 to rotate, and the screw 108 is driven to rotate by the driving motor 109, thereby driving the protective cover 106 to rise and fall.

[0024] At the same time, the fixed seat 110 is fixedly connected to the base 101 and is rotatably connected to the screw 108. A bearing is provided inside the fixed seat 110. The bottom end of the screw 108 extends into the fixed seat 110 and is fixedly connected to the inner ring of the bearing. Through the fixed seat 110, the screw 108 is stably supported.

[0025] In addition, the damper 111 is fixed on the inner wall of the protective cover 106; the buffer plate 112 is fixedly connected to the end of the damper 111; the buffer spring 113 is sleeved on the outside of the damper 111 and is located between the protective cover 106 and the buffer plate 112. The buffer plate 112 is used to directly contact the fragments. The damper 111 can absorb the impact force generated when the fragments hit the buffer plate 112. The buffer spring 113 plays a role of elastic support. Through the cooperation of the damper 111 and the buffer spring 113, the movement potential energy of the fragments is reduced.

[0026] In this embodiment, when in use, the fastener is first clamped onto the tensile machine body 102, and then the drive motor 109 is controlled to move. The drive motor 109 drives the screw 108 to rotate, thereby driving the protective cover 106 to move downward until it is closed with the base 101. After that, the tensile machine body 102 can be started to perform a breaking test on the fastener. During the process, the fragments generated when the fastener is broken will be confined in the protective cover 106, and the impact force of the fragments will be absorbed by the damper 111 and the buffer spring 113. By setting the protective cover 106, the flying fragments can be blocked and the kinetic potential energy of the fragments can be reduced, thereby ensuring the safety of the staff, and solving the problem that the fragments will fly after the fastener breaks, and the prior art does not have a protective device, which can easily cause injuries to the staff.

[0027] The second embodiment of the present application is:

[0028] See also Figure 3 , Figure 3 2 is a schematic diagram of the overall structure of a fastener mold according to a second embodiment of the present utility model. Based on the first embodiment, the fastener mold of this embodiment further includes a support spring 201 and a clamping block 202 .

[0029] In this embodiment, the driving member further includes a supporting spring 201 and a clamping block 202. The above solution can reduce the impact force and vibration when the protective cover 106 is closed.

[0030] Among them, the support spring 201 is sleeved on the outside of the column 103 and is located at the bottom end of the column 103; the block 202 is slidably connected with the column 103 and is located at the end of the support spring 201. The number of the support springs 201 is four, which are respectively sleeved on the tops of the four columns 103. The blocks 202 are four groups, and one group has two. The two blocks 202 are respectively located at the upper and lower ends of the support spring 201. The blocks 202 have a groove matching the outer diameter of the support spring 201. The support spring 201 can be limited by the groove to prevent the support spring 201 from shifting. Through the support spring 201, the impact force and vibration of the protective cover 106 when it is closed can be reduced.

[0031] In this embodiment, when the protective cover 106 closes downward, it collides with the base 101. Through the support spring 201, the protective cover 106 is subjected to a certain elastic damping during the descent process, thereby slowing down the descent speed and reducing sudden impact and vibration.

[0032] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
