Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of floor spring, specifically is a floor spring cover fixing structure. BACKGROUND

[0002] Floor spring is a kind of hydraulic door closer, just the device of compressing spring is worm gear instead of gear rack.Because worm gear can rotate in both directions, so floor spring can be used for the door of two-way opening, and door closer can only be used for the door of one-way opening.

[0003] After the existing floor spring is out of market, because cover and machine body are connected by thread, in the process of transportation and use, cover will gradually slide out along thread in reverse direction due to reasons such as vibration, to cause the problems of product defect, short service life and cumbersome maintenance in later period. UTILITY MODEL CONTENT

[0004] In view of the deficiency of prior art, the utility model provides a floor spring cover fixing structure, solves the problems of product defect, short service life and cumbersome maintenance in later period due to the fact that cover and machine body are connected by thread, in the process of transportation and use, cover will gradually slide out along thread in reverse direction due to reasons such as vibration.

[0005] To realize the above purpose, the utility model is realized by the following technical scheme: a floor spring cover fixing structure, including machine body, the top of machine body is equipped with cover by thread, and the edge of cover is equipped with arc concave position, and the surface of machine body is equipped with screw by thread through screw hole, and screw is located in arc concave position and is fastened.

[0006] Preferably, the surface of the cover is symmetrically provided with a groove.

[0007] The utility model provides a floor spring cover fixing structure.Compared with the prior art, it has the following advantages:

[0008] The floor spring cover fixing structure has at least one arc concave position on one side of the cover, a screw is designed beside the arc concave position, and a part of the screw cap presses the arc concave position of the cover, achieving positioning design so that the cover will not loosen.

[0012] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0013] Please refer to Figs. 1-2 The utility model provides a technical scheme: a ground spring cover fixing structure, including body 1, the top of body 1 is equipped with cover 2 by screwing, and the edge of cover 2 is equipped with arc concave position 4, and the surface of body 1 is equipped with screw 3 by screw hole 5, and screw 3 is located in arc concave position 4 and is fastened, the screw cap of screw 3 presses the arc concave position 4 of cover 2, is set by limiting, and cover 2 will not back off.

[0014] Further, the surface of cover 2 is symmetrically equipped with a groove, wherein the cover 2 is installed on the body 1 by inserting the tweezers into the groove and rotating the cover 2, and the position of the arc concave position 4 will be aligned with the screw hole 5.

[0015] When working or using, the cover 2 is installed on the body 1 by inserting the tweezers into the groove and rotating the cover 2, and the position of the arc concave position 4 will be aligned with the screw hole 5, then the screw 3 is fixedly installed in the screw hole 5, and the screw cap of the screw 3 presses the arc concave position 4 of the cover 2, and the cover 2 will not back off by limiting.

[0016] Meanwhile, the contents not described in detail in the specification all belong to the prior art known by those skilled in the art.

[0017] It should be noted that, in this document, relative terms such as first and second, and the like, are used to differentiate one entity or action from another, but do not necessarily require or imply that any such actual relationship or order exists between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without more limitations, the statement "comprises... means" does not exclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the stated elements.

[0018] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
