Description

Technical Field

[0001] This application relates to the field of special vehicle-mounted extended shelters, and more particularly to a clamping handle with a tensioning function. Background Technology

[0002] After the top panel of a flip-up, pull-out expandable cabin unfolds upwards, it must be locked to the side panels to prevent it from tumbling down. A sealing strip between the top and side panels creates a top seal, and the clamping handle is a crucial component ensuring the seal at the connection between the top and side panels. Traditional clamping handles simply limit the top panel's position by turning it, preventing it from falling. This single-function handle cannot guarantee the sealing performance between the top and side panels and is unsuitable for use in flip-up, pull-out expandable cabins. Utility Model Content

[0003] The main purpose of this application is to provide a clamping handle with a tensioning function, which aims to solve the problem that existing clamping handles cannot guarantee the sealing performance between the expansion top plate and the expansion side plate.

[0004] To achieve the above objectives, this application provides a clamping handle with a tensioning function, comprising: a first base, on which a second limiting plate is vertically connected via a first limiting plate, the first limiting plate and the second limiting plate forming a lock on the first base; a second base, with the second limiting plate facing away from the second base; a handle rotatably connected to the surface of the second base, one end of the handle being connected to a locking tongue, the handle rotating around the second base, and locking by engaging the locking tongue within the lock.

[0005] Optionally, a positioning groove is provided on the inner surface of the second limiting plate, and a protrusion adapted to the positioning groove is provided on the surface of the lock tongue, the protrusion being located within the positioning groove; the sum of the thickness of the protrusion and the thickness of the lock tongue is less than the distance between the second limiting plate and the second base.

[0006] Optionally, a groove is provided on the handle, and a first through hole is provided at the bottom of the groove. The size of the first through hole is smaller than the size of the groove. A rotating connector is provided in the groove, and one end of the rotating connector passes through the first through hole and is rotatably connected to the second base.

[0007] Optionally, the latch includes a first connecting plate, one end of which is connected to a handle, and the other end is vertically connected to a second connecting plate, the first connecting plate and the second connecting plate forming a hook structure; in the locked state, the second connecting plate is located inside the lock.

[0008] Optionally, a wedge surface is formed on the second limiting plate, and the locking tongue enters the lock along the wedge surface.

[0009] Optionally, a through hole is provided at the other end of the handle.

[0010] Compared with the prior art, the beneficial effects of this application are as follows: The clamping handle with tensioning function of this utility model forms a lock on the first base through the first and second limiting plates. The locking tongue limits the height of the lock and exerts tension force to lock and seal the extended top plate and extended side plate. The handle rotates around the second base, causing the locking tongue to move closer to or away from the lock, which is convenient for operation. After the extended compartment is closed, the space where the clamping handle is installed is relatively small, and the thickness of the handle is small, which can meet the usage requirements of such a small space as the extended compartment.

[0012] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0014] An embodiment of this utility model provides a clamping handle with a tensioning function, such as... Figure 1-2As shown, it includes a first base 1 and a second base 2. The surface of the first base 1 is vertically connected to a second limiting plate 4 via a first limiting plate 3. The first limiting plate 3 and the second limiting plate 4 form a lock on the first base 1. The second limiting plate 4 faces away from the second base 2. A handle 5 is rotatably connected to the surface of the second base 2. One end of the handle 5 is connected to a locking tongue 6. The handle 5 rotates around the second base 2 and is locked by engaging with the locking tongue 6 in the lock.

[0015] In this embodiment, as Figure 3-4 As shown, in use, the second base 2 is fixed to the mounting seat on the extended top plate and the first base 1 on the extended side plate. By rotating the handle 5, the locking tongue 6 moves towards the lock and engages in the lock, thus locking; the locking tongue 6 moves in the opposite direction, away from the lock, thus unlocking. The first limiting plate 3 and the second limiting plate 4 form the lock on the first base 1. The locking tongue 6 limits the height of the lock and provides tension, thus locking and sealing the extended top plate and the extended side plate. The handle 5 rotates around the second base 2, causing the locking tongue 6 to move closer to or away from the lock, facilitating operation. After the extended compartment is retracted, the space for the clamping handle in this embodiment is relatively small, and the thickness of the handle 5 is small, which meets the usage requirements of such a small space in the extended compartment.

[0016] Furthermore, such as Figure 5-6 As shown, a positioning groove 7 is formed on the inner surface of the second limiting plate 4, and a protrusion 8 adapted to the positioning groove 7 is provided on the surface of the latch 6. The protrusion 8 is located in the positioning groove 7. The sum of the thickness of the protrusion 8 and the thickness of the latch 6 is less than the distance between the second limiting plate 4 and the second base 2. A wedge surface is formed on the second limiting plate 4, and the latch 6 enters the lock along the wedge surface.

[0017] In this embodiment, the sum of the thicknesses of the protrusion 8 and the locking tongue 6 is less than the distance between the second limiting plate 4 and the second base 2. This distance difference should not be too large, as long as it ensures that the protrusion 8 can enter between the second limiting plate 4 and the second base 2. This distance difference and the wedge surface on the second limiting plate 4 can both ensure that the locking tongue 6 enters between the second limiting plate 4 and the second base 2, preventing the second base 2 and the first base 1 from being non-coplanar and causing a jamming phenomenon. The protrusion 8 cooperates with the positioning groove 7 to limit the locking tongue 6 and prevent the locking tongue 6 from sliding out after locking.

[0018] Furthermore, the handle 5 has a groove 9, and a first through hole 10 is formed at the bottom of the groove 9. The size of the first through hole 10 is smaller than the size of the groove 9. A rotating connector is provided in the groove 9, and one end of the rotating connector passes through the first through hole 10 and is rotatably connected to the second base 2. For example, the rotating connector can be a hot-riveted rivet, which improves the connection strength while ensuring rotation.

[0019] Specifically, the locking tongue 6 includes a first connecting plate 61, one end of which is connected to the handle 5, and the other end is vertically connected to a second connecting plate 62. The first connecting plate 61 and the second connecting plate 62 form a hook structure. In the locked state, the second connecting plate 62 is located inside the lock. The hook structure formed by the first connecting plate 61 and the second connecting plate 62 not only limits the position of the extended top plate, but also creates a tension force between the second connecting plate 62 and the second limiting plate 4, tightening the extended top plate and the extended side plate to ensure sealing.

[0020] The other end of the handle 5 has a second through hole 11. In addition to rotating the handle 5 by hand, the second through hole 11 can also be operated by inserting other tools into the hole.

[0021] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
