Abstract
The utility model provides a connecting structure for an inner casing and an outer casing of an ignition gun, which relates to ignition guns, and solves the technical problem of low assembly efficiency of an inner casing and an outer casing of an existing ignition gun. The connecting structure of an inner casing and an outer casing of an ignition gun comprises the inner casing and the outer casing sleeved outside the inner casing, and is characterized in that a barb is disposed on one side of the bottom of the inner casing, a hook of the barb faces outwards, and a projection positioned on the barb is formed on the inner wall of the lower portion of the outer casing. The inner casing is connected with the outer casing in a fastening manner, the outer casing can be sleeved into and released from the inner casing conveniently and simply, assembly efficiency is improved, the outer casing can be rapidly replaced at any time so as to meet requirements of some consumers on rapidly replacing outer casings in different colors, component damage caused by forceful separating the inner casing from the outer casing is effectively avoided by the aid of a detaching hole, and the service life of the ignition gun is prolonged.
Description
Technical field
The utility model relates to burning torch, the syndeton of especially a kind of burning torch inner casing and shell.
Background technology
Present a kind of burning torch, its rifle shell is that shell and inner casing fit form, inner casing is fixedlyed connected by screw with shell, installation and removal all comparatively bother, not only efficiency of assembling is low, and in the face of some consumer the time, also can't satisfy the demand that they change the different colours shell fast.
Summary of the invention
The purpose of this utility model is that a kind of shell syndeton of burning torch inner casing and shell fast, easily of changing is provided in order to solve above-mentioned the deficiencies in the prior art.
In order to achieve the above object, a kind of burning torch inner casing that the utility model is designed and the syndeton of shell, comprise inner casing and be enclosed within the outer shell of inner casing, a side that it is characterized in that described inner shell bottom is provided with a barb, the hook portion of this barb forms a protuberance that is positioned on the described barb outwardly on the inwall of described outer casing underpart.When outside when trying hard to recommend shell and being inserted in inner casing, protuberance pushes barb and makes barb generation elastic deformation, utilizes resetting of barb that itself and protuberance are interlocked subsequently; In the time of shell and inner casing will being broken away from, firmly shell is extracted and got final product.Shell is inserted in and to break away from inner casing convenient and simple, has improved efficiency of assembling, and can change shell at any time, apace, satisfies the demand that some consumer changes the different colours shell fast.
Improve and replenish as the further of said structure, the utility model also comprises any combination of following additional technical feature or these features:
The bottom of described shell has the removal hole that is positioned under the described barb, pass removal hole by instrument, withstand barb, make barb generation deformation, can reduce shell break away from inner casing required firmly, the parts damages that bring in the time of also can avoiding inner casing and shell to break away from firmly.
The lateral surface of the hook portion of described barb is an inclined-plane, and protuberance slips into along the inclined-plane, and it is more light, laborsaving that inner casing is inserted in shell.
Form many convex tendons on the lateral wall of described outer casing underpart, increase the coefficient of friction at convex tendon position, firmly convenient.
One side of described inner shell bottom forms unfilled corner, and the unfilled corner place is provided with a barb that is connected as a single entity with inner casing, space availability ratio height.
Inner casing of the present utility model is connected by buckle-type with shell, shell is inserted in and to break away from inner casing convenient and simple, improved efficiency of assembling, and can change shell at any time, apace, satisfy the demand that some consumer changes the different colours shell fast, the parts damages that bring when utilizing removal hole effectively to avoid inner casing and shell to break away from firmly increase the service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the broken section enlarged drawing of Fig. 1;
Fig. 3 is a blast structural representation of the present utility model.
Among the figure: 1-inner casing, 2-shell, 3-protuberance, 4-barb, 5-removal hole, 6-convex tendon.
The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of burning torch inner casing that present embodiment is described and the syndeton of shell, comprise inner casing 1 and the shell 2 that is enclosed within outside the inner casing 1, one side of described inner casing 1 bottom forms unfilled corner, the unfilled corner place is provided with a barb 4 that is connected as a single entity with inner casing 1, and the material of barb 4 is the rubber-like plastics.Barb 4 has with inner casing 1 unfilled corner place sidewall is convenient to the space that deformation take place barb 4, and the hook portion of this barb 4 forms a protuberance 3 that is used with described barb 4 outwardly on the inwall of described shell 2 bottoms.The bottom of described shell 2 has the removal hole 5 that is positioned under the described barb 4, and the lateral surface of the hook portion of described barb 4 is an inclined-plane.Form two annular convex ribs 6 on the lateral wall of described shell 2 bottoms, also can be many.
