Description

Technical Field

[0001] This utility model belongs to the field of bolt technology, and in particular relates to a bolt that prevents blockage. Background Technology

[0002] Pins are mainly used to lock or fix the position of two objects. A pin usually consists of a bolt and a fixing part. The movable bar on the bolt can be inserted into the fixing part to lock or fix it. The structural design of the pin will vary depending on the application. When pins are used outdoors or in harsh environments, small particles such as dust, dirt, and debris may enter the bolt or fixing part of the pin. As small particles accumulate, the movable bar on the bolt may not be able to be properly inserted into the fixing part or may be difficult to pull out of the fixing part. This requires operators to clean and maintain the pin frequently, which is very inconvenient to use. Therefore, it is necessary to improve the pin for this application. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned technical problems by providing an anti-clogging pin. This pin separates the interior of the plug housing and the fixing housing from the outside, preventing the accumulation of tiny particles inside the plug housing and the fixing housing, thus ensuring the long-term stable use of the pin without the need for frequent cleaning and maintenance by operators.

[0004] In view of this, the present invention provides an anti-clogging latch, comprising:

[0005] The bolt housing has a movable groove that extends through one end of the bolt housing, and a push groove that connects to the movable groove is provided on the bolt housing.

[0006] The movable strip is slidably disposed in the movable groove along the first direction. One end of the movable strip can extend out of the movable groove. The movable strip is provided with a push block that can pass through the push groove. The movable strip can always block the push groove during the sliding process.

[0007] A fixed housing is provided on one side of the movable bar in the first direction, and the fixed housing is provided with a slot for the end of the movable bar to be inserted.

[0008] A baffle is movably installed in the fixed housing. The baffle can block and allow the slot opening to pass through.

[0009] In this technical solution, the bolt housing and the fixed housing are respectively installed on two objects at appropriate positions. When the operator applies force to the push block, the movable strip can be pushed back and forth in the first direction. During the process of the movable strip being inserted into the slot, the baffle can open the slot opening, allowing the end of the movable strip to be inserted into the slot to lock the two objects. After the movable strip is removed from the slot, the baffle can block the slot opening, isolating the inside of the fixed housing from the outside world and preventing the accumulation of small particles in the slot. The movable strip always blocks the push groove during the sliding process, isolating the inside of the bolt housing from the outside world and preventing the accumulation of small particles in the movable groove, thus ensuring the long-term stable use of the pin.

[0010] In the above technical solution, the fixed housing is further provided with a mounting groove with a connecting slot, one end of the baffle is rotatably mounted on the side wall of the mounting groove, and a torsional elastic element is provided between the baffle and the side wall of the mounting groove.

[0011] In the above technical solution, the mounting groove penetrates the outer wall of the fixed housing, the baffle can pass through the mounting groove, and the fixed housing is provided with a detachable first cover plate, which can block the opening of the mounting groove.

[0012] In the above technical solution, mounting holes are provided on both opposite side walls of the fixed housing, and shaft portions are provided on both sides of the connecting end of the baffle. One end of the connector passes through the mounting hole and connects to the shaft portion.

[0013] In the above technical solution, a guide groove adapted to the width of the shaft is provided on the side wall of the mounting groove, and the mounting hole communicates with the guide groove.

[0014] In the above technical solution, both the push groove and the movable groove penetrate the side wall of the bolt housing away from the fixed housing. The bolt housing is provided with a detachable second cover plate, which includes a first sealing part and a second sealing part. The first sealing part can block the opening of the movable groove, and the second sealing part can block the opening of the push groove.

[0015] In the above technical solution, the second sealing part is further made of an elastic material.

[0016] Furthermore, in the above technical solution, both the bolt housing and the fixing housing are provided with mounting parts.

[0017] The beneficial effects of this utility model are:

[0018] 1. By installing the movable strip in a relatively sealed manner within the bolt housing, external microparticles are prevented from entering the movable groove, ensuring that the movable strip can slide stably relative to the bolt housing. By setting a movable baffle to block and conduct the slot, the slot opening is blocked when the slot is not engaged with the movable strip, preventing microparticles from accumulating in the slot. This avoids the pin being blocked by microparticles and ensures the long-term stable use of the pin.

[0019] 2. By designing the baffle so that one end is rotatably connected in the fixed housing, and setting a torsional elastic element to drive the baffle to reset, after the movable bar moves in the first direction and contacts the baffle, the movable bar continues to move in the first direction to squeeze the baffle and open the slot. During this process, the torsional elastic element is squeezed, and the movable bar can be smoothly inserted into the slot. After the movable bar exits the slot, the elastic force of the torsional elastic element can reset the baffle and re-block the slot opening. This achieves automatic blocking and opening of the slot opening, which is convenient to use.

[0020] 3. By setting an installation groove in the fixed housing and setting a removable first cover plate to block the groove opening, the pin can be used stably while the baffle can be easily installed and removed.

[0021] 4. By designing the push groove and the movable groove to penetrate the side wall of the bolt housing away from the fixed housing, and by setting a removable second cover plate to block the openings of the movable groove and the push groove, the stability of the bolt can be ensured while the movable strip can be easily disassembled and assembled.

[0034] Example 1

[0035] like Figures 1-4 As shown, this embodiment provides an anti-clogging pin, including: a pin housing 1, a movable strip 2, a fixed housing 4, and a baffle 5;

[0036] Please see Figure 3and Figure 4 The bolt housing 1 is provided with a movable groove 101, which passes through one end of the bolt housing 1. The bolt housing 1 is provided with a push groove 102 that communicates with the movable groove 101.

[0037] Please see Figure 3 and Figure 4 The movable strip 2 is slidably disposed in the movable groove 101 along the first direction X. One end of the movable strip 2 can extend out of the movable groove 101. The side wall of the movable strip 2 is in contact with the side wall of the movable groove 101, or there is only a small gap between them. Tiny particles cannot pass through the gap and enter the movable groove 101. The movable strip 2 is provided with a push block 3 that can pass through the push groove 102. By applying force to the push block 3, the movable strip 2 can be driven to slide back and forth in the movable groove 101 along the first direction X.

[0038] Please see Figure 3 The push block 3 is positioned near the middle of the movable bar 2. When one end of the movable bar 2 is inserted into the slot 401, the other end of the movable bar 2 will not be exposed in the push groove 102, so that the movable bar 2 can always block the push groove 102 during the sliding process.

[0039] Please see Figure 4 The fixed housing 4 is located on one side of the movable bar 2 in the first direction X, and the fixed housing 4 is provided with a slot 401 for the end of the movable bar 2 to be inserted.

[0040] The baffle 5 is movably mounted in the fixed housing 4. Please refer to [link / reference]. Figure 1 After the movable bar 2 exits the slot 401, the baffle 5 can block the slot opening of the slot 401. Please refer to [link / reference]. Figure 2 During the process of inserting the movable strip 2 into the slot 401, the baffle 5 can conduct the slot opening of the slot 401; in this embodiment, the baffle 5 can be slidably set in the fixed housing 4 or rotated in the fixed housing 4. Generally, the baffle 5 is driven to move manually. The setting method that can block and conduct the slot opening of the slot 401 in the prior art can be used as the setting method of the baffle 5 in this embodiment.

[0041] In this embodiment, both the bolt housing 1 and the fixed housing 4 are provided with mounting parts 9, which can be used to mount the bolt housing 1 or the fixed housing 4 onto an object.

[0042] In this embodiment, the bolt housing 1 and the fixed housing 4 are respectively installed on two objects at appropriate positions. When the operator applies force to the push block 3, the movable bar 2 can be pushed back and forth in the first direction X. During the process of the movable bar 2 being inserted into the slot 401, the baffle 5 can open the slot 401, so that the end of the movable bar 2 can be inserted into the slot 401 to lock the two objects. After the movable bar 2 is removed from the slot 401, the baffle 5 can block the slot 401, separating the inside of the fixed housing 4 from the outside, and preventing small particles from accumulating in the slot 401. During the sliding process, the movable bar 2 always blocks the push groove 102, separating the inside of the bolt housing 1 from the outside, preventing small particles from accumulating in the movable groove 101, and ensuring the long-term stable use of the bolt.

[0043] Example 2

[0044] Based on Embodiment 1, this embodiment also discloses an installation method of the baffle 5 in the fixed housing 4;

[0045] Please see Figure 3 The fixed housing 4 is provided with a mounting groove 402 that connects to the slot 401. One end of the baffle 5 is rotatably mounted on the side wall of the mounting groove 402. A torsional elastic element (not shown in the figure) is provided between the baffle 5 and the side wall of the mounting groove 402.

[0046] In this embodiment, the torsional elastic element can be a torsion spring;

[0047] In this embodiment, after the end of the movable strip 2 is inserted into the slot 401, the movable end of the baffle 5 is blocked by the movable strip 2. At this time, the torsional elastic element is in a compressed state. During the process of the movable strip 2 exiting the slot 401, after the movable strip 2 separates from the baffle 5, the torsional elastic element resets and drives the movable end of the baffle 5 to swing toward the opening of the slot 401. For the setting of the swing endpoint of the baffle 5, please refer to [link to relevant documentation]. Figure 3 A groove is provided on the side wall of the slot 401 away from the connecting end of the baffle 5, so that a structure is provided at the slot 401 to block the movable end of the baffle 5. When the movable end of the baffle 5 contacts the side wall of the groove, the baffle 5 cannot continue to swing. At this time, the baffle 5 completely blocks the slot 401.

[0048] When it is necessary to insert the movable bar 2 into the slot 401, the movable bar 2 moves in the first direction X and comes into contact with the baffle 5. At this time, the movable bar 2 continues to move in the first direction X to squeeze the baffle 5 and push the movable end of the baffle 5 into the slot 401. During this process, the torsional elastic element is squeezed, and the slot 401 is gradually opened, so the movable bar 2 can be smoothly inserted into the slot 401.

[0062] When installing the baffle 5, the shaft portions 501 on both sides of the baffle 5 are pushed into the mounting groove 402 along the two guide grooves 404. When the shaft portions 501 are pushed to the end of the guide groove 404, the mounting hole 403 is aligned with the threaded hole on the shaft portion 501, which reduces the difficulty of installing and positioning the baffle 5.

[0063] Example 6

[0064] Based on Embodiment 1, this embodiment also discloses an installation method of the movable strip 2 in the bolt housing 1;

[0065] In this embodiment, please refer to Figure 6 and Figure 7 Both the push groove 102 and the movable groove 101 penetrate the side wall of the bolt housing 1 away from the fixed housing 4. The bolt housing 1 is provided with a detachable second cover plate, which includes a first sealing part 7 and a second sealing part 8. The first sealing part 7 can block the opening of the movable groove 101, and the second sealing part 8 can block the opening of the push groove 102.

[0066] Specifically, the first sealing part 7 and the second sealing part 8 can be integrally formed or fixedly connected separately.

Then, the movable strip 2 is pushed along the first direction X by the push block 3. Then, the second cover plate is installed on the bolt housing 1. At this time, the first sealing part 7 blocks the groove opening of the movable groove 101 away from the fixed housing 4, and the second sealing part 8 blocks the groove opening of the push groove 102 away from the fixed housing 4, thereby isolating the movable groove 101 from the outside.

[0068] Example 7

[0069] Based on Example 6, this embodiment further specifies the material of the second sealing part 8;

[0070] In this embodiment, the second sealing part 8 is made of elastic material. Since the push block 3 needs to move back and forth in the first direction X during the use of the pin, the operator may cause the push block 3 to contact or collide with the second sealing part 8 when the movable bar 2 is withdrawing from the slot 401. If the second sealing part 8 is made of rigid material, it may affect the stable connection between the second cover plate and the bolt housing 1. Over time, it will affect the isolation effect between the movable slot 101 and the outside world. However, the second sealing part 8 is made of elastic material, which can buffer the force generated by the contact when the push block 3 contacts or collides with the second sealing part 8, and extend the service life of the second cover plate.
