Description
Technical Field
The utility model relates to a draw bar structure for reflow soldering installs on reflow soldering's upper cover and fuselage, and mainly used supports reflow soldering's upper cover.
Background
During the operation of reflow soldering, the upper cover of the reflow soldering needs to be opened frequently due to the requirements of maintenance and cleaning. However, the upper cover of reflow soldering is generally very heavy, and after the upper cover is opened, the upper cover is often held by one person, which is very inconvenient and brings great inconvenience to production and maintenance.
On the other hand, the opened reflow soldering upper cover is heavy, the temperature inside the reflow soldering is high, and if the reflow soldering upper cover is suddenly closed, certain potential safety hazards exist.
Disclosure of Invention
The utility model aims to solve the technical problem that a pull rod structure for reflow soldering that structural design is reasonable, the support is firm, installation convenient to use is provided.
The utility model provides a technical scheme that above-mentioned technical problem adopted is this a pull rod structure for reflow soldering, its structural feature is: the pull rod comprises a pull rod body, an inner retainer ring, an outer retainer ring and a fixing pin, wherein one end of the pull rod body is provided with an upper cover connecting rod, the upper cover connecting rod penetrates through a hole formed in an upper cover, the upper cover connecting rod is fixed with the upper cover through the inner retainer ring and the outer retainer ring, and the upper cover connecting rod can rotate in the hole of the upper cover; one end of the pull rod body is provided with a fixing pin, a fixing pin groove is formed in the inner side of the reflow soldering machine body, and the fixing pin is arranged in the fixing pin groove.
Further, the edge contact department of fixed pin and fixed pin groove be provided with the packing ring.
Further, the edge contact department of fixed pin and fixed pin groove be provided with the gyro wheel.
Further, fixed round pin groove on be provided with spacing hole, spacing hole matches each other with the diameter and the shape of fixed pin.
Furthermore, the number of the limiting holes is 1-5.
Compared with the prior art, the utility model have following advantage and effect: because the pull rod with two bent ends is arranged. The upper cover can be effectively supported in the opening process. The upper cover is prevented from falling suddenly and is not required to be manually held. And particularly the angle at which the upper cover is opened, can be controlled in cooperation with a fixing pin groove in which the upper cover can slide. Furthermore, the upper cover can be fixed at an opened position by matching with the arrangement of the limiting hole, so that the support is firmer and more stable.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is the schematic view of the local structure of the reflow soldering upper cover when the reflow soldering upper cover is opened after the pull rod of the utility model is installed.
Fig. 3 is a schematic view of the perspective structure of the reflow soldering upper cover of the utility model when the reflow soldering upper cover is closed after the pull rod is installed.
Description of reference numerals: the pull rod comprises a pull rod body 1, an inner retainer ring 2, an outer retainer ring 3, a gasket 4, an upper cover connecting rod 5, a fixing pin 6, a fixing pin groove 7, a reflow soldering machine body 8, a limiting pin 9 and a limiting hole 10.
Detailed Description
The present invention will be described in further detail with reference to the following examples, which are illustrative of the present invention and are not intended to limit the present invention.
Example 1:
as shown in fig. 1 to 3, the present embodiment describes a tie bar structure for reflow soldering, the main body of the tie bar structure for reflow soldering is a tie bar body 1, the tie bar body 1 is a rod-shaped structure with two bent ends, and the length of the tie bar body is matched with the size of a reflow soldering upper cover. Its one end is buckled 90 degrees and is formed upper cover connecting rod 5, and upper cover connecting rod 5 passes the hole of covering on the reflow soldering, by interior retaining ring 2, outer retaining ring 3 common fixed position, the position of upper cover connecting rod 5 is restricted jointly to interior retaining ring 2 and outer retaining ring 3, but upper cover connecting rod 5 can be in the hole free rotation of covering on the reflow soldering.
The other end of the pull rod body 1 is also bent by 90 degrees, a longitudinal fixing pin 6 is formed at the tail end, the fixing pin 6 is installed in a fixing pin groove 7 on a reflow soldering machine body 8, a gasket 4 is sleeved at the contact position of the pull rod body 1 and the fixing pin groove 7, and the gasket 4 is fixed by a limiting pin 9.
The pull rod body 1 can slide along the fixed pin slot 7, so that the reflow soldering upper cover is driven to be opened at different angles. In the fixed pin slot 7, a plurality of limiting holes 10 are further arranged, and the limiting holes 10 can be clamped into different limiting holes 10 according to requirements so as to fix the opening angle of the upper cover.
The washer 4 in this embodiment is to ensure the free sliding of the fixing pin 6 in the fixing pin slot 7, and may be replaced by a roller.
Generally speaking, the pull rod body 1 is the Z style of calligraphy, and the one end of upper cover connecting rod 5 is the L type, and the one end of fixed pin 6 is T type structure, and L type one end is fixed and is covered on, and T type structure is in the activity of reflow soldering fuselage 8's fixed keyway 7.
In addition, it should be noted that the specific embodiments described in the present specification may differ in the shape of the components, the names of the components, and the like. All equivalent or simple changes made according to the structure, characteristics and principle of the utility model are included in the protection scope of the utility model. Various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
