[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0030] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indications will also change accordingly.

[0031] In this application, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] In addition, in this application, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" can explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement.

[0033] The strength of bolts is generally detected by a tensile testing machine, which usually includes a machine body and a clamping assembly. The clamping assembly is usually divided into an upper fixing part and a lower fixing part. The upper fixing part and the lower fixing part are respectively fixed to both ends of the bolt. When in use, the lower fixing part remains stationary, and the upper fixing part slides on the machine body in the vertical direction. The upper fixing part and the lower fixing part cooperate to stretch the bolt until it breaks, so as to realize the detection of the bolt performance.

[0034] In the related art, by providing a protective cover between the upper fixing part and the lower fixing part, the protective cover can intercept some of the flying specimens, thereby reducing the possibility of specimens flying out and causing harm to experimental personnel. And the protective cover is set as a telescopic structure, so that the protective cover can completely cover between the upper fixing part and the lower fixing part, thereby reducing the possibility of some specimens flying out from the gap between the protective cover and the machine body, and further ensuring the safety of the operator. However, in actual use, the protective cover always occupies a large usage area, has a relatively single function, and cannot collect debris, having certain limitations.

[0035] To solve the problems in the related art to a certain extent, the embodiment of this application provides a bolt strength detection device. When in use, only need to manually push the telescopic mechanism 13 to make the telescopic mechanism 13 extend or retract, and then fix the heights of both ends of the telescopic mechanism 13 by inserting the clamping block 22 into the hole body 24. Subsequently, the flying debris falls into the drawer 30 after contacting the inner side of the telescopic mechanism 13, which is more convenient and fast, improving the convenience of the device.

[0036] The present application will be described below in conjunction with the accompanying drawings and with reference to specific embodiments:

[0037] In conjunction with Figures 1 - 5 , an embodiment of the present application provides a bolt strength detection device, including: a tensile testing machine 10, on which a chute 11 is provided, a slider 12 is slidably connected in the chute 11, a telescopic mechanism 13 is provided on the slider 12, a fixed block 14 is fixedly connected to one side of the telescopic mechanism 13, frame bodies 20 are fixedly connected to both the telescopic mechanism 13 and the side of the fixed block 14, a round-headed rod 21 is slidably connected in the frame body 20, a clamping block 22 is fixedly connected to one end of the round-headed rod 21, a spring 23 is sleeved outside the round-headed rod 21, both ends of the spring 23 are fixedly connected to the clamping block 22 and the frame body 20 respectively, a hole 24 is provided on the side of the tensile testing machine 10, and the spring 23 is inserted into the hole 24, and a drawer 30 is slidably connected in the telescopic mechanism 13.

[0038] When in use, after placing the tensile testing machine 10 at a specified position, fix the bolt to be detected (the model of the tensile testing machine 10 is JHY-5000, and the fixing of the bolt and subsequent detection are all prior arts, so no more details will be given), then pull outwards the round-headed rod 21 on the frame body 20 on the side of the fixed block 14, so that the corresponding clamping block 22 slides out of the hole 24, then manually push the telescopic mechanism 13, so that the telescopic mechanism 13 drives the slider 12 to slide up and down in the chute 11 to realize the adjustment of the height of the telescopic mechanism 13. Then, after pulling outwards the round-headed rod 21 on the side of the telescopic mechanism 13, when the corresponding clamping block 22 slides out of the hole 24, pull the telescopic mechanism 13 to make the telescopic mechanism 13 automatically extend or contract to cover the detection area and play a role of covering and protecting. After that, through the resilience of the spring 23, push the clamping block 22 to insert into the hole 24 at the specified position to complete the fixation of the height and the elongation distance of the telescopic mechanism 13, and then normal detection can be carried out. During the detection process, when splashing occurs, after the debris contacts the inner side of the telescopic mechanism 13, the debris falls into the drawer 30 to realize the collection of the debris.

[0039] Specifically, the telescopic mechanism 13 is composed of a plurality of plate bodies with a C-shaped cross-section, and a slider and a chute are provided between adjacent two plate bodies, as Figure 3 and Figure 4 are the front view and the rear view of the telescopic mechanism 13.

[0040] Specifically, a sponge is adhesively bonded to the inner side of the telescopic mechanism 13. When debris splashes, it contacts the sponge to reduce the rebound, so that the debris can fall into the drawer 30.

[0041] In some embodiments, the chute 11 penetrates through the top of the tensile testing machine 10, so that when the slider 12 slides out from the top end of the chute 11, disassembly is realized, and vice versa for installation.

[0042] In some embodiments, the frame body 20, the round head rod 21, the clamping block 22, the spring 23 and the hole body 24 form a group, and multiple groups are arranged on the telescopic mechanism 13, so that multiple clamping blocks 22 are inserted into multiple hole bodies 24 at the same time, improving the fixing effect.

[0043] In some embodiments, a fixing seat 31 is fixedly connected to the bottom of the telescopic mechanism 13, a baffle 32 is slidably connected in the fixing seat 31, and the baffle 32 is in close contact with the telescopic mechanism 13.

[0044] When the drawer 30 needs to be cleaned, push the baffle 32 to make the baffle 32 slide in the fixing seat 31 until the baffle 32 is separated from the drawer 30, and then directly pull the drawer 30 to make the drawer 30 slide out of the telescopic mechanism 13, and then recycle the debris in the drawer 30.

[0045] In some embodiments, a plate body 50 is fixedly connected to the outside of the clamping block 22, the plate body 50 penetrates through the frame body 20, a rod body one 51 is fixedly connected to the side surface of the fixing block 14, the rod body one 51 penetrates through the frame body 20, a rod body two 52 is fixedly connected to one end of the plate body 50, a rod body three 53 is slidably connected in the fixing seat 31, one end of the rod body three 53 penetrates through the baffle 32, and the other end is in close contact with the rod body two 52.

[0046] After pulling the round head rod 21, the round head rod 21 drives the clamping block 22 and the plate body 50 to slide on the frame body 20. The rod body one 51 restricts the plate body 50 to only slide horizontally. While the plate body 50 slides, it drives the rod body two 52 to slide away from the rod body three 53. After canceling the limit on the rod body three 53, it is convenient to push the rod body three 53 and the baffle 32. On the contrary, when the clamping block 22 is inserted into the hole body 24, the rod body two 52 pushes the rod body three 53, so that the rod body three 53 clamps the baffle 32 with the fixing seat 31, and the baffle 32 has a good limiting effect on the drawer 30.

[0047] In some embodiments, a limiting ring is fixedly connected to the outside of the rod body three 53. During use, the limiting ring has a good limiting effect on the baffle 32.

[0048] In some embodiments, a housing 40 is fixedly connected to the outside of the fixing block 14, and the housing 40 covers the rod body two 52 and the plate body 50, playing a role of covering and protecting.

[0049] In some embodiments, the hole body 24 is a countersunk hole, which is convenient for the clamping block 22 to be inserted into the hole body 24.

[0050] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "examples", "specific examples", "some examples", etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine the different embodiments or examples described in this specification.

[0051] In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.
