[0026] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0027] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0028] As described in the background technology, in the field of aerospace, a locking strip refers to a device used for the rapid locking and disassembly of various boards and modules, and has high thermal conductivity, anti-vibration capability, and high reliability. The utility model with publication number CN206196210U applied by the applicant in 2016 discloses a pull-out aviation chassis locking strip that can complete rapid locking and disassembly, but the locking strip is independent. When installing the chassis, two or more locking strips may be required. These locking strips are also controlled separately and cannot be linked, which makes the installation or removal of the locking strip complicated.

[0029] Based on the above reasons, Figure 1-Figure 6 As shown, this embodiment provides a connecting rod locking strip, including a connecting rod body 100, the connecting rod body 100 includes a connecting rod 101, and at least two locking bodies 200 arranged in parallel are installed on the connecting rod 101;

[0030] The locking body 200 includes a mounting shaft 205, a locking portion 203 and a pushing portion. The locking portion 203 and the pushing portion are mounted on the mounting shaft 205. The locking portion 203 and the pushing portion cooperate with each other through an inclined surface. The locking portion 203 can slide out of the mounting shaft 205 as a whole. Among the pushing portions, at least one portion including the inclined surface can slide along the axis of the mounting shaft.

[0031] The connecting rod 101 is provided with the same number of connecting parts 102 as the locking body, and each connecting part 102 is connected to the installation shaft 205 of the locking body 200 through a connecting shaft 201;

[0032] One end of the connecting shaft 201 is rotatably connected to the connecting portion 102 via a pin shaft 300, and the other end is connected to the mounting shaft 205;

[0033] The connecting part 102 has a protrusion that acts on the movement of the pushing part. The protrusion pushes the pushing part to move under the rotation of the connecting part. An elastic component 204 that drives the pushing part to reset is installed on the connecting shaft. The elastic component can be a spring.

[0034] The above-mentioned technical features, through the design of the connecting rod, can realize one action to drive multiple locking bodies to move simultaneously, and complete the unlocking or locking of multiple locking bodies through one operation, which is convenient to operate; and it is driven in the form of an eccentric protrusion. When the connecting rod is moved, the connecting rod drives the protrusion to rotate, and the joint action of the protrusion and the elastic component drives the pushing part to move, and the pushing part then drives the locking strip to move, thereby completing the locking or unlocking.

[0035] In order to facilitate the staff to move the connecting rod, in one embodiment, the connecting rod body 101 has a handle 103 .

[0036] In order to better achieve the inclined surface fit between the pushing portion and the locking portion, in one embodiment, as Figure 4-Figure 6 As shown, the pushing part includes a first push block 202 and a second push block 209, both of which are matched with the locking part by inclined surfaces, the first push block 202 is slidably mounted on the mounting shaft 205 and is located at one end close to the connecting rod 101, and the second push block 209 is mounted on the mounting shaft 205 and away from the connecting rod 101; in order to improve the locking and prevent loosening, an elastic member 207 acting on the second push block 209 and mounted on the mounting shaft 205 is provided on the outer side of the second push block 209. In order to better push the pushing part, a cushion block 400 is installed on the connecting shaft 201, and the cushion block 400 is located between the convex portion and the first push block 202.

[0037] In order to improve the pushing effect, in one embodiment, the inclined surface connecting the first pushing block and the locking portion is symmetrically arranged with the inclined surface connecting the second pushing block and the locking portion.

[0038] In order to improve the protection effect, in one embodiment, Figure 6As shown, a cover 208 mounted on the mounting shaft 205 is provided on the periphery of the elastic member 207. The cover 208 is mounted on the end of the mounting shaft 205 through a bolt 206, and the elastic member 207 is mounted on the bolt 206, one end of the elastic member 207 acts on the end face of the bolt, and the other end acts on the second push block; the elastic member is a spring or a spring sheet or a spring sheet group formed by a plurality of spring sheets.

[0039] like Figure 7 As shown, when the utility model is in use, the two locking bodies 200 are respectively installed on both sides of the template, and the staff moves the handle of the connecting rod. When the connecting rod is moved, the connecting part rotates, and the convex part of the connecting part acts on the first push block through the cushion block. The first push block drives the locking part to slide outward of the installation shaft as a whole or be retracted under the action of the elastic component, thereby achieving locking or unlocking.

[0040] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
