[0036] 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.

[0037] 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.

[0038] As described in the background technology, the utility model with publication number CN206196210U applied by the applicant in 2016 discloses a pull-out type aviation chassis locking strip, which can complete quick locking and disassembly, but is locked and unlocked by a pull-out rod. When the pull-out rod is pulled, since the pull-out rod needs to be rotated, there are space requirements, which is not suitable for scenes with small space and has limited usage conditions.

[0039] Based on this problem, this embodiment provides a push-type locking strip, such as Figure 1-Figure 5 As shown, the locking strip includes a locking body, which includes a mounting shaft 6, a locking portion 5 and a pushing portion. The locking portion 5 and the pushing portion are mounted on the mounting shaft 6. The locking portion and the pushing portion are matched through an inclined surface. The locking portion can slide out of the mounting shaft 6 as a whole. Among the pushing portions, at least one portion including the inclined surface can slide along the axis of the mounting shaft.

[0040] The push-type locking strip also includes a push-locking head that drives the pushing portion to drive the locking portion to slide on the mounting shaft 6 in a push-rebound manner;

[0041] The push-lock head includes a slide bar 9, a shell 2, a slide slot push rod 12 and a thrust rod 3, so that one end of the slide bar is fixedly connected to the mounting shaft 6, the shell 2 is fixedly connected to the other end of the slide bar 9, and the slide slot push rod 12 is slidably mounted on the shell 2;

[0042] The thrust rod 3 is slidably mounted on the slide bar 9, one end of which acts on the pushing portion, and the other end of the thrust rod cooperates with the housing 2 using a stepped slope 23;

[0043] An elastic component 11 (optionally, the elastic component is a spring) is installed between the pushing portion and the installation shaft 6 .

[0044] The above technical features can achieve locking and unlocking by pressing and rebounding. The operation space is small and it can be used as long as the locking strip can be installed. There is no need to rely on knob locking. The locking strip can be locked or unlocked without tools. While ensuring the locking force, it is also very convenient for maintenance personnel to disassemble and assemble.

[0045] When in use, the push rod and the pushing part are driven to move by pressing the slide groove top rod, and the pushing part then pushes the locking part as a whole to slide outward from the installation shaft through the inclined surface, and under the action of the elastic component, the thrust rod cooperates with the high inclined surface of the step inclined surface, thereby achieving locking; when the slide groove top rod is pressed again, the slide groove top rod pushes the thrust rod again, and the thrust rod rotates under the joint action of the inclined surface of the step inclined surface and the elastic component, thereby cooperating with the low inclined surface, and the locking part retreats, thereby achieving unlocking.

[0046] In order to achieve press rebound, for example, with the cooperation of the elastic component, Fig.12 As shown, the thrust rod 3 is provided with a guide portion 32 and a plurality of thrust teeth 31, the end surface of the thrust tooth is an inclined surface adapted to the stepped inclined surface 23; the guide portion 32 is inserted into the slide slot top rod 12, and a plurality of guide convex teeth (such as Fig.15 as shown).

[0047] In order to better realize the step-bevel fit between the thrust rod and the housing, for example, Figure 9-11 As shown, the end surface of the housing 2 close to the sliding rod is provided with a plurality of stepped inclined surfaces 23 , and a sliding groove 22 is provided between each group of stepped inclined surfaces 23 .

[0048] In order to facilitate the staff to press the chute top rod, in one embodiment, the end of the chute top rod 12 passes through the housing 2, and a button 1 is fixedly connected to the end of the chute top rod 12. The staff drives the chute top rod by pressing the button.

[0049] In order to better push the locking part, in one embodiment, as Figure 1-Figure 5 As shown, the pushing portion includes a first pushing block 4 and a second pushing block 7, both of which use inclined surfaces to cooperate with the locking portion 5, the first pushing block 4 is slidably mounted on the mounting shaft 6 and is located at one end close to the slide bar 9, the second pushing block 7 is mounted on the mounting shaft 6 and away from the slide bar 9, and an elastic member 82 is provided on the outer side of the second pushing block 7, which acts on the second pushing block 7 and is mounted on the mounting shaft 6. 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. The elastic member 82 can achieve anti-loosening.

[0050] In order to improve the locking effect and the protective effect, in one embodiment, a cover body 8 installed on the mounting shaft 6 is provided on the periphery of the elastic member 82. The cover body is installed on the end of the mounting shaft 6 through a bolt 81, and the elastic member is installed on the bolt 81. One end of the elastic member 82 acts on the end face of the bolt, and the other end acts on the second push block 7 or the isomorphic cover body 8 to transmit the action on the second push block 7; the elastic member is a spring or a spring sheet or a spring sheet group formed by several spring sheets.

[0051] The utility model has a reasonable design, a simple structure, and is easy to use. Locking and unlocking are achieved by pressing and rebounding. The operation space is small and it can be used as long as the locking strip can be installed. There is no need to rely on knob locking. The locking strip can be locked or unlocked without tools. While ensuring the locking force, it is also very convenient for maintenance personnel to disassemble and assemble.

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.
