Abstract

(57) [Summary] [Purpose] To easily attach sheet metal or molded products to a board at predetermined intervals using spacers, and to easily remove them. [Structure] By screwing the screw rod 4 into the through-screw hole 2 formed in the center of the spacer body 1, the elastic locking claw 3 formed integrally at one end of the spacer body 1 resists elasticity. The spacer body 1 is configured to be expanded and deformed so that the screws 4 screw the substrate 5 and the spacer body 1, and the locking claws 3 lock and fix the sheet metal or molded product 7 and the spacer body 1 at the same time. do.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This device can be used to fix sheet metal or molded products to a substrate at predetermined intervals. This relates to the spacer used.

0002

[Conventional technology]

FIG. 5 is a sectional view showing how this type of conventional spacer is used. , 11 is a spacer body, and on both ends of this spacer body 11 there are approximately umbrella-shaped finger holes. The locking claws 12 and 13, which can be deformed to reduce their diameter against elasticity by applying an external force, are It is integrally formed. 15 is a substrate, 17 is a sheet metal or a molded product, and these include It has a smaller diameter than the spacer body 11 and is large enough to allow the reduced diameter locking claws 12 and 13 to pass through. Holes 16 and 18 are formed.

0003 Next, the operation of the spacer having the above configuration will be explained. First, one of the locking claws 12 is slightly bent and deformed into the hole 16 of the board 15 with the fingers. At the same time, manually insert the other locking claw 13 into the hole 18 of the sheet metal or molded product 17. Insert it by bending it slightly with your finger. In this way, both the locking claws 12 and 13 are in the hole. 16, 18, the deflection of these locking claws 12, 13 returns and the spacer book The substrate 15 and the sheet metal or molded product 17 are fixed between the spacer body 11 and the spacer body 1. The substrate 15 and the sheet metal or molded product 17 are fixed at an interval corresponding to the thickness of 1. to hold.

0004

[Problem that the idea aims to solve]

Since the conventional spacer is configured as described above, the spacer near the hole 16 on the substrate 15 If other parts or heat sinks are crowded together, or if the back of the sheet metal or molded product 17 Parts, etc. are provided so as to surround the hole 18 on the side, so that it is difficult for fingers to enter. In this case, there was a problem in that it was very difficult to remove the spacer.

[0005] This idea was made to solve the above problems, and it is easy to operate. This allows the spacer body to be fixed to the board and the locking claws to lock the sheet metal or molded product. The spacer body and sheet metal can be removed from the board at the same time. Or provide a spacer that allows molded products to be removed extremely easily. The purpose is to

[0006]

[Means to solve the problem]

The spacer according to this invention has one end of the spacer body with a through screw hole in the center. This spacer has an integrally formed elastic locking claw that can be expanded and deformed against elasticity. The above elastic locking pawl is expanded and deformed by inserting a headed screw into the through-screw hole in the body. It is characterized by being configured to allow

[0007]

[Effect]

According to this invention, the screw rod is screwed into the through screw hole in the center of the spacer body. Attach sheet metal or molded parts to the board at predetermined intervals by It can be easily installed or removed.

[0008]

【Example】

An embodiment of this invention will be described below based on the drawings. FIG. 1 is a perspective view showing a spacer according to an embodiment of this invention. , 1 is a spacer body made of plastic molding, and the center of this spacer body 1 has a A tapered through screw hole is formed. 3 is one end of the spacer body 1 It is an elastic locking claw that is integrally formed in the It is molded into a pa shape. 4 is a screw rod that can be screwed into the through-screw hole 2; A head portion 4a having a large diameter is formed. 5 is a substrate with a hole 6, 7 is a substrate with a hole 8. It is a sheet metal or molded product.

[0009] Next, the operation of the above configuration will be explained. First, as shown in FIG. Insert it into the hole 8 of the sheet metal or molded product 7 as shown by arrow b until it locks. Koto The locking pawl 3 is smaller than the hole 8 of the sheet metal or molded product 7, and has a tapered shape. Therefore, the locking pawl 3 can be easily inserted into the hole 8. Next, S With the back side of the hole 6 of the board 5 in contact with one side of the pacer body 1, press the front side of the board 5. Insert the screw rod 4 through the hole 6, and insert the screw rod 4 into the through hole of the spacer body 1. Insert the screw into 2. As a result, as shown in Fig. 3, the locking pawl 3 is expanded and deformed against elasticity. is engaged with the hole 8 of the sheet metal or molded product 7, and the screw rod 4 engages the substrate 5. is screwed to the spacer main body 1, and the board 5 and the sheet metal or molded product 7 are held between a predetermined distance. fixed at a distance.

0010 Also, from the above fixed state, screw the threaded rod 4 in the direction of arrow a as shown in FIG. When it is returned, the screws between the board 5 and the spacer body 1 are removed, and the locking claws 3 become elastic. It returns to its original shape due to its elastic restoring force and can be easily removed from the hole 8 of the sheet metal 7. Thereby, the fixation between the substrate 5 and the sheet metal or the molded product 7 is released.

[0011]

[Effect of the idea]

As described above, according to this invention, the screw rod can be removed from one end of the spacer body. By removing it, the locking fixation by the locking claw on the other end of the spacer body can be released. The removal work, which conventionally required two steps, can now be done in one simple step. It also allows for a larger work space, making removal work easier. can be significantly improved. Moreover, there is no need to elastically deform the locking claw with your fingers, so it can be used even in narrow spaces. This has the effect that removal can be easily performed.
