Abstract
Description
Technical Field
[0001] This utility model relates to the field of equipment compartment cover technology, specifically to an embedded rotary unlocking external handle device. Background Technology
[0002] The equipment compartment cover of a trailer is an indispensable part of the trailer design. It is mainly used to protect the internal equipment of the trailer (such as toolboxes, batteries, hydraulic systems, etc.) from the influence of the external environment (such as rain, dust, vibration, etc.).
[0003] The external handle on the equipment hatch is a key component that allows users to directly interact with the hatch, and its design directly affects the ease of operation, safety, and overall user experience. Most external handles on the equipment hatches of traditional trailers use simple pull rings or hook-like structures, which are simple in structure and easy to operate. However, most of these external handles lack an effective locking mechanism, which can easily cause the equipment hatch to open accidentally due to external force or vibration during driving, posing a safety hazard. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an embedded rotary unlocking external handle device, which solves the problem that the external handle on the cover of existing equipment is easily opened by external force.
[0005] An embedded rotary unlocking device with an external pry handle includes:
[0006] A base, comprising a mounting groove and an outer mounting edge circumferentially fixed thereon along the opening of the mounting groove;
[0007] The limiting assembly includes an operating member rotatably mounted between the inner and outer sides of a mounting groove, a limiting member slidably disposed between the inner and outer sides of one side of the mounting groove, and a transmission member disposed between the operating member and the limiting member; and
[0008] A locking assembly includes a lock body fixedly mounted between the inner and outer sides of a mounting groove via a fixing seat, and a locking member rotatably disposed within the mounting groove. The power output end of the lock body is connected to the locking member, and the locking member is used to abut against the rotation of a limiting member to restrict the limiting state of the limiting member.
[0009] The rotating operating component drives the limiting component to slide between the inner and outer sides of the mounting groove via the transmission component.
[0010] Compared with the prior art, this utility model has the following advantages: In use, the mounting groove is embedded into the equipment compartment cover and fixed by the assembly outer edge. When the equipment compartment cover is closed, the rotating operating component drives the limiting component to move into the mounting groove through the transmission component. Then the equipment compartment cover is closed. Subsequently, the operating component is rotated in the opposite direction to reset the limiting component and engage with the compartment body to limit the equipment compartment cover. At the same time, the lock body is turned by the key, which drives the locking component to rotate and resist the limiting component to ensure that the limiting component cannot slide in the mounting groove. This ensures the stability of the equipment compartment cover and prevents the equipment compartment cover from being opened accidentally due to external force or vibration during driving. Moreover, the entire embedded rotary unlocking handle device has a simple structure and is easy to operate.
[0011] Preferably, the transmission components are arranged in two sets facing each other between the operating component and the limiting component. Each transmission component includes a meshing sector gear and several assembly teeth. The sector gear is connected to the operating component, and the several assembly teeth are arranged linearly at intervals on the limiting component.
[0012] Preferably, the limiting member includes a slider that is slidably disposed at the bottom of the mounting groove and a limiting block that slides through one side of the mounting groove. The limiting block is fixedly connected to the slider. Each set of assembly teeth is arranged linearly at intervals on the slider. The locking member is used to resist the rotation of the slider.
[0013] Preferably, the operating component includes a handle body that is rotatably mounted between the inner and outer sides of the mounting groove via a rotating shaft. Each end of the rotating shaft is fitted with a torsion spring, and each torsion spring is elastically connected between the handle body and the inner wall of the mounting groove.
[0014] Preferably, the slider has an arc-shaped groove on the side away from the limiting block, and the locking member includes a locking rod with one end fixedly connected to the power output end of the lock body, and the other end of the locking rod is used to rotate and abut against the inner wall of the arc-shaped groove.
[0015] Preferably, a fixing plate is fixedly installed between the fixing base and the inner wall of the mounting groove. The fixing plate has a rotating hole. The handle body is located above the fixing plate. Each sector gear freely passes through the rotating hole and meshes with a number of corresponding assembly teeth.
[0016] Preferably, the handle body includes an operating section and a connecting section fixedly connected thereto. The rotating shaft is fixedly and through-connected to the connecting section. The thickness of the connecting section is greater than the thickness of the operating section. The connecting section is used to rotate and abut against the fixed plate.
[0017] Preferably, two limiting plates are fixedly installed at the bottom of the mounting groove, and the two limiting plates are used to limit the rotation range of the locking rod.
[0018] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0027] To make the technical means, creative features, achieved objectives and functions of this utility model clearer and easier to understand, the utility model will be further described below with reference to the accompanying drawings and specific embodiments:
[0028] like Figure 1-2As shown, an embodiment of this utility model provides an embedded rotary unlocking handle device, comprising: a base, which includes a mounting groove 1 and an assembly outer edge 11 fixedly mounted thereon along the circumferential opening of the mounting groove 1; a limiting assembly, which includes an operating member rotatably mounted between the inner and outer sides of the mounting groove 1, a limiting member slidably passing through the inner and outer sides of one side of the mounting groove 1, and a transmission member disposed between the operating member and the limiting member; and a locking assembly, which includes a lock body 5 fixedly mounted between the inner and outer sides of the mounting groove 1 via a fixing seat 4 and a locking member rotatably disposed within the mounting groove 1, wherein the power output end of the lock body 5 is connected to the locking member, and the locking member is used to rotate against the limiting member to limit the limiting state of the limiting member; the rotating operating member drives the limiting member to slide between the inner and outer sides of the mounting groove 1 via the transmission member.
[0029] The mounting groove 1 is embedded into the equipment compartment cover 7 and fixed by the assembly outer edge 11. When the equipment compartment cover 7 is closed, the rotating operating component drives the limiting component to move into the mounting groove 1 through the transmission component. Then the equipment compartment cover 7 is closed. Subsequently, the operating component is rotated in the opposite direction to reset the limiting component and engage with the compartment body 8 to limit the equipment compartment cover 7. At the same time, the lock body 5 is turned by the key, which drives the locking component to rotate and resist the limiting component to ensure that the limiting component cannot slide in the mounting groove 1. This ensures the stability of the limiting of the equipment compartment cover 7 and prevents the equipment compartment cover 7 from being opened accidentally due to external force or bumps and vibrations during driving. Moreover, the entire embedded rotary unlocking handle device has a simple structure and is easy to operate.
[0030] Preferably, the outer edge 11 of the assembly is provided with a plurality of connecting holes 12 along its circumference to facilitate fixing the mounting groove 1.
[0031] like Figure 2 as well as Figure 4-5 As shown, according to another embodiment of the present invention, the embedded rotary unlocking external handle device further optimizes its transmission components, limiting components, operating components, and locking components. The transmission components are arranged in two sets facing each other between the operating component and the limiting component. Each transmission component includes a sector gear 21 that meshes with each other and a plurality of assembly teeth 31. The sector gear 21 is connected to the operating component, and the plurality of assembly teeth 31 are arranged linearly at intervals on the limiting component. Rotating the operating component drives the limiting component to slide through the transmission of the sector gear 21 and the plurality of assembly teeth 31.
[0032] The limiting component includes a slider 3 slidably disposed at the bottom of the mounting groove 1 and a limiting block 32 slidably passing through one side of the mounting groove 1. The limiting block 32 is fixedly connected to the slider 3. Each plurality of assembly teeth 31 are arranged linearly at intervals on the slider 3. The locking component is used to resist the rotation of the slider 3. The sliding of the slider 3 drives the limiting block 32 to move between the inner and outer sides of the mounting groove 1.
[0033] The operating component includes a handle body 2 rotatably mounted between the inner and outer sides of the mounting groove 1 via a rotating shaft 22. Each end of the rotating shaft 22 is fitted with a torsion spring 23, and each torsion spring 23 is elastically connected between the handle body 2 and the inner wall of the mounting groove 1. When the handle body 2 rotates, it will cause the two torsion springs 23 to deform elastically. After the handle body 2 is released, the handle body 2 can quickly return to its original position under the action of the elastic force of the two torsion springs 23.
[0034] The slider 3 has an arc-shaped groove 33 on the side away from the limiting block 32. The locking component includes a locking rod 6 with one end fixedly connected to the power output end of the lock body 5. The other end of the locking rod 6 is used to rotate and abut against the inner wall of the arc-shaped groove 33. By abutting against the inner wall of the arc-shaped groove 33, the slider 3 can be limited, ensuring the stability of the limiting block 32 in limiting the equipment compartment cover 7.
[0035] like Figure 2 As shown, according to another embodiment of the present utility model, the embedded rotary unlocking external handle device preferably has a fixing plate 13 fixedly installed between the fixing base 4 and the inner wall of the mounting groove 1. The fixing plate 13 has a rotating hole 14. The handle body 2 is located above the fixing plate 13. Each sector gear 21 freely passes through the rotating hole 14 and meshes with a corresponding number of assembly teeth 31.
[0036] Furthermore, the handle body 2 includes an operating section and a connecting section fixedly connected thereto. The rotating shaft 22 is fixedly and through the connecting section. The thickness of the connecting section is greater than the thickness of the operating section. The connecting section is used to rotate and abut against the fixed plate 13. Since the thickness of the connecting section is greater than the thickness of the operating section, and the connecting section abuts against the fixed plate 13, sufficient operating space can be ensured between the operating section and the fixed plate 13.
[0037] like Figure 2-3 As shown, according to another embodiment of the present invention, the embedded rotary unlocking external handle device preferably has two limiting plates 15 fixedly installed at the bottom of the mounting groove 1. The two limiting plates 15 are used to limit the rotation range of the locking rod 6, ensuring that the locking rod 6 can disengage from the arc-shaped groove 33 due to excessive rotation.
[0038] The working principle of this utility model is as follows: When using this utility model, the mounting groove 1 is embedded into the equipment compartment cover 7 and fixed by several connecting holes 12 on the outer edge 11. When closing the equipment compartment cover 7, the handle body 2 is rotated, which drives the two torsion springs 23 to deform elastically. Then, through the transmission of each sector gear 21 and the corresponding several assembly teeth 31, the slider 3 and the limiting block 32 are driven to move into the mounting groove 1. Then, the equipment compartment cover 7 is closed by rotating. After the equipment compartment cover 7 has moved into place, the handle body 2 is released. Under the elastic force of the two torsion springs 23, the handle body 2 is driven to return to its original position. Through the transmission of the sector gear 21 and the several assembly teeth 31, the slider 3 and the limiting block 32 are driven to move out of the mounting groove 1. The limiting block 32 is engaged with the compartment body 8 to limit and fix the equipment compartment cover 7. Then, the lock body 5 is turned by the key, which drives the locking rod 6 to rotate and abut against the inner wall of the arc groove 33 to lock the position of the slider 3, thereby ensuring the stability of the limiting block 32 in limiting the equipment compartment cover 7.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
